[0001] 1. Field of the Invention

[0002] The present invention relates to a portable terminal device, and a displaying method for the portable terminal device. More particularly, the present invention relates to a wireless portable terminal device having a folding structure that permits a first housing and a second housing to turn on a hinge, and a displaying method and a program for the wireless portable terminal device.

[0003] 2. Description of the Related Art

[0004] In recent years, portable telephone terminals and wireless portable terminals have had a mail message transmitting/receiving feature and a browser. In order to make the most of the features, more and more terminals have rapidly come to include a large-color screen display device. A folding terminal has become a mainstream of terminals having a large-screen display device mounted therein.

[0005] FIGS. 1A and 1B show the appearance of a wireless portable terminal having a folding structure. FIG. 1A shows the appearance with the folding terminal left open, FIG. 1B shows the appearance with the folding terminal closed. Referring to FIG. 1A, the folding wireless portable terminal has the folding structure permitting a body 1 that is a first housing and a cover 2 that is a second housing to turn on a hinge 3. With the hinge 3 as an axis, the terminal can be folded or unfolded in directions of arrows in FIG. 1A. An antenna 4 transmits or receives a radio wave. The body 1 includes an operator panel 5 that is an input means which the user of the terminal maneuvers. The cover 2 includes a first display device 6 that is a main display means of the terminal.

[0006] When the folding wireless portable terminal is folded, the display device 6 is opposed to the body 1 and located internally of the terminal. The user of the terminal cannot therefore check the contents of a presentation displayed on the display screen of the display device 6. A terminal having a second display device mounted on the outer surface of the folded terminal has made its debut so as to help the user of the terminal check necessary minimal information with the terminal folded.

[0007] Referring to FIG. 1B, the folding wireless portable terminal has a second display device 7 mounted as an auxiliary display means on a surface opposite to the surface of the cover 2 on which the first display device 6 is mounted. With the folding terminal closed, the second display device 7 has the ability to help the user check necessary minimal information alone. Moreover, with the folding terminal left open, the presenting action of the second display device 7 is generally disabled for the reason that the user has difficulty in checking the contents of a presentation displayed on the second display device 7 or for the purpose of extending the service life of a battery even slightly.

[0008] The necessary minimal information to be displayed on the second display device 7 includes a remaining battery capacity, a presentation of whether the present place is inside or outside a communication-enabled zone, and a mail message termination presentation “New Mail Terminated” signifying that a mail message has been terminated. If the terminal is a portable telephone terminal, a voice termination presentation “Call Terminated” indicating that voice has been terminated is also included.

[0009] However, when the wireless portable terminal having the folding structure has received a mail message, if “New Mail Terminated” is displayed on the second display device 7, the user cannot find the contents of the received mail message. In order to check the contents of the newly received mail message, the user has to perform a maneuver of opening the terminal, and a maneuver of designating the received mail message to thus display the contents of the mail message on the first display device 6. This is labor-intensive. There is a possibility that the contents of the mail message read by performing the maneuvers may not be the contents of the mail message the user wants to check immediately.

[0010] The present invention is devised in view of the above-described problems. An aspect of the present invention is to provide a portable terminal device, and a displaying method and a program for the terminal device which enables the user to check the contents of received data, which the user wants to read, without the necessity of performing a special maneuver with the terminal closed.

On the other hand, the second display displays the message information when the second information set matches the sender information, and a message showing the arrival of the data when the second information set does not match the sender information. The data may be an electronic mail message.

[0016] And then, a portable terminal device of the present invention comprises a memory that stores a first information set, a timer that counts to a predetermined time, an outputting circuit that outputs a signal when the timer counts up to the predetermined time, a connector that connects to a predetermined server in response to the signal, a receiver that receives data including a second information set from the predetermined server, a display that displays received message included in the data, a detector that detects whether the portable terminal device is closed, a comparator that compares the first information set with the second information set and a controller that controls whether the second information set is displayed on the display on the basis of the results of the detector and the comparator. The display is provided at a position visible to the user with the portable terminal device closed. The controller controls the display to display the received message when the portable terminal device is closed. The controller controls the display to display the received message when the first information set matches the second information set. On the other hand, the controller controls the display to display additional information showing the arrival of the data when the first information set does not match the second information set. The second information set is title name of the data, the data may be an HTML file, and the predetermined server may be an information distribution server.

[0017] A method for controlling display of messages in a folding portable terminal device of the present invention comprises storing a first information set, receiving data including a second information set, detecting whether the terminal device is closed, comparing the first information set with the second information set, displaying received message, included in the data, on first display provided at a position visible to the user with the terminal device closed, both if the terminal device is closed and if the first information set matches the second information set. The method further comprises displaying additional information showing the arrival of the data on second display provided at a position invisible to the user with the terminal device closed, if the terminal device is opened. The second information set is at least one of title and sender name of the data. The data may be an electronic mail message.

[0018] Moreover, a method for controlling display of messages in a folding portable terminal device of the present invention comprises storing a first information set, counting a predetermined time, outputting a signal when the predetermined time is counted up, connecting a predetermined server in response to the signal, receiving data including a second information set from the predetermined server, detecting whether the terminal device is closed, comparing the first information set with the second information set and displaying received message included in the data on first display provided at a position visible to the user with the terminal device closed, both if the terminal device is closed and if the first information set matches the second information set. The method further comprises displaying additional information showing the arrival of the data on second display provided at a position invisible to the user with the terminal device closed, if the terminal device is opened. The second information set is title name of the data. The data may be an HTML file, and the predetermined server may be an information distribution.

[0019] A program for instructing a computer to implement a displaying method for a folding portable terminal device of the present invention comprises storing a first information set, receiving data including a second information set, detecting whether the terminal device is closed, comparing the first information set with the second information set, displaying received message, included in the data, on first display provided at a position visible to the user with the terminal device closed, both if the terminal device is closed and if the first information set matches the second information set.

[0020] Further, a program for instructing a computer to implement a displaying method for a folding portable terminal device of the present invention comprises storing a first information set, counting a predetermined time, outputting a signal when the predetermined time is counted up, connecting a predetermined server in response to the signal, receiving data including a second information set from the predetermined server, detecting whether the terminal device is closed, comparing the first information set with the second information set and displaying received message included in the data on first display provided at a position visible to the user with the terminal device closed, both if the terminal device is closed and if the first information set matches the second information set.

[0021] According to the present invention, therefore, the user can check the contents of received data he/she wants to read with the terminal device closed without the necessity of performing a special maneuver. This is because as long as data received by the portable terminal device having the folding structure is information (designated information) the user wants to check, the received data is displayed on the display device located at a position making the display device visible to the user even with the folding terminal device closed. According to the present invention, moreover, the shortening of the service life of a battery loaded in the terminal device can be minimized. This is because only when received data is information the user wants to check, the received data is displayed on the display device. In other words, every time the terminal device receives data, the received data is screened so that only information the user desires can be displayed on the display device. Compared with when all received data items are displayed but not screened, the power consumption required for the displaying can be suppressed.

[0031] Hereinafter, each embodiment of the present invention will be described in detail with reference to the drawings.

[0032] FIG. 2 is a block diagram showing the configuration of a portable terminal device in accordance with the first embodiment of the present invention. Incidentally, the appearance of the portable terminal device in accordance with the first embodiment of the present invention is shown in FIG. 1A and FIG. 1B, and has already been described. The reiteration of the appearance will be omitted.

[0033] Referring to FIG. 2, the portable terminal device having a folding structure in accordance with the first embodiment of the present invention includes an antenna 101, a wireless device 102, a control unit 103, a first driver 104, a first display device 105, a second driver 106, a second display device 107, a memory 108, a mail processing unit 109, a designated character string storage device 110, a comparing means 111, an open/close detecting unit 112, a notifying means 113, and an operator panel 114.

[0034] The antenna 101 transmits or receives a radio wave and is comparable to the antenna 4 shown in FIG. 1A and FIG. 1B. The wireless device 102 modulates transmission data or demodulates received data. The wireless device 102 amplifies and demodulates data the antenna 101 has received over a wireless network, and transfers the resultant data as demodulated signal to the control unit 103. Moreover, the wireless device 102 modulates data sent from the control unit 103 as transmission data, and transfers the transmission data to the antenna 101.

[0035] When a mail message is received (terminated), the control unit 103 cuts out mail data from a digital signal that results from demodulation performed by the wireless device 102, and stores the mail data in the memory 108. The sampled mail data contains a mail header and a mail text defined by, for example, the Request for Comments (RFC) 822.

[0036] Moreover, the control unit 103 controls the presentations of the first display device 105 and second display device 107 via the first driver 104 and second driver 106. Furthermore, when a mail message is terminated, the control unit 103 controls the notifying means 113 to notify the user of the terminal of the fact that a mail message has been received. The notifying means 113 is realized with a vibrator, a light-emitting diode (LED), or a loudspeaker.

[0037] The operator panel 114 is an input means the user uses to determine various settings for the terminal. The control unit 103 processes a signal entered by maneuvering the operator panel 114 and then detected. Incidentally, the operator panel 114 is comparable to the operator panel 5 shown in FIG. 1A.

[0038] The first display device 105 serves as a main display means of the terminal, and is realized with, for example, a color liquid crystal display. Incidentally, the first display device 105 is comparable to the first display device 6 shown in FIG. 1A. With the folding terminal closed, the first display device 105 is opposed to the first housing (body 1) and located internally of the terminal. The user cannot therefore watch the first display device 105.

[0039] The second display device 107 serves as an auxiliary display means for the terminal, and is realized with, for example, a black-and-white liquid crystal display. Incidentally, the second display device 107 is comparable to the second display device 7 shown in FIG. 1B. The second display device 107 is mounted on the surface of the second housing (cover 2) opposite to the surface on which the first display device 105 is mounted. Therefore, the user can watch the second display device 107 with the folding terminal closed.

[0040] The second display device 107 presents information when the terminal is detected to be closed at the open/close detecting unit 112. With the terminal left open, the second display device 107 is controlled to have the presentation thereof disabled for the reason that the user has difficulty in discerning the contents of a presentation or for the purpose of extending the service life of a battery.

[0041] The memory 108 is a memory means in which a received mail message is stored. The mail processing unit 109 analyzes header information of newly received mail data that is cut out by the control unit 103. The mail processing unit 109 then cuts out a character string representing the title of a received mail message specified in the header information and a character string representing the originator (mail address) of the received mail message. Incidentally, the character string representing the title of the received mail message and the character string representing the originator thereof constitute the data in the first predetermined division of the received data.

[0042] The designated character string storage device 110 is a holding means that holds a first character string representing the title of a received mail message and a second character string representing the originator of the received mail message. The user enters the first and second character strings in advance by maneuvering the operator panel 114. Namely, the first and second character strings are used to judge whether a received mail message is information the user wants to check.

[0043] The comparing means 111 compares the character string representing the title of the received mail message, which is sampled by the mail processing unit 109, with the first character string stored in the designated character string storage device 110. The result of the comparison, whether the character strings agree or disagree with each other, is transferred to the control unit 103. Moreover, the comparing means 111 compares the character string representing the originator of the received mail message, which is sampled by the mail processing unit 109, with the second character string stored in the designated character string storage device 110. The result of the comparison, whether the character strings agree or disagree with each other, is transferred to the control unit 103.

[0044] The open/close detecting unit 112 detects whether the folding terminal is closed or open, and transfers the result of the detection to the control unit 103.

[0045] FIG. 3 shows an example of the structure of the designated character string storage device 110 shown in FIG. 2. Referring to FIG. 3, the designated character string storage device 110 has N (where N denotes a positive integer) pairs of a title designation area and an originator designation area. Data to be recorded in the title designation area is the first character string which the user enters in advance by maneuvering the operator panel 114. Moreover, data to be recorded in the originator designation area is the second character string the user enters in advance by maneuvering the operator panel 114.

[0046] Up to N pairs of character strings can be recorded in the N pairs of the title designation area and originator designation area in the designated character string storage device 110. Assume that whether the contents of a received mail message is displayed on the second display device 107 is judged by comparing only a character string representing the title of a received mail message with a stored one. In this case, the first character string alone is recorded in the title designation area, and data indicating the absence of a character string is recorded in the originator designation area paired with the title designation area. An example of this pair is provided as the pair of the title designation area 2 and originator designation area 2 shown in FIG. 3.

[0047] Similarly, when only a character string representing the originator of a received mail message is compared with a stored one, the second character string is recorded in the originator designation area, and data indicating the absence of a character string is recorded in the title designation area paired with the originator designation area. Using the operator panel 114, the user enters a character string equivalent to the character string representing the title of a mail message whose contents the user wants to be displayed on the second display device 107. The user also enters a character string equivalent to the character string representing the originator of the mail message. The entered character strings are then processed by the control unit 103 and stored in the designated character string storage device 110.

[0048] Next, the actions of the portable terminal device in accordance with the first embodiment of the present invention will be described in conjunction with the drawings. FIG. 4 is a flowchart describing actions to be performed when the portable terminal device shown in FIG. 2 has received a mail message.

[0049] Referring to FIG. 4, the portable terminal device in accordance with the first embodiment of the present invention receives a mail message (S401). The control unit 103 cuts out mail data and stores the newly received mail in the memory 108 (S402). Thereafter, the control unit 103 judges from the result of detection provided by the open/close detecting unit 112 whether the terminal device is closed or open (S403).

[0050] If the terminal device is closed (the judgment of S403 is made in the affirmative), the mail processing unit 109 analyzes the header information of the received mail message sent from the control unit 103. The mail processing unit 109 then cuts out the title of the received mail message and the originator's address thereof, and transfers the character strings to the control unit 103 (S404). The control unit 103 initializes a parameter n to 1 so as to count the number of times by repetitive processing is performed (S405). Thereafter, the control unit 103 judges whether a character string is recorded in the title designation area 1 or originator designation area 1 in the designated character string storage device 110 (S406).

[0051] If a character string is recorded in the title designation area 1 or originator designation area 1 (the judgment of S406 is made in the affirmative), it is judged whether a character string is recorded in the title designation area 1 (S407). If a character string is recorded in the title designation area 1 (the judgment of S407 is made in the affirmative), the character string representing the title of the received mail message is compared with the recorded character string (S408). If the character string representing the title of the received mail message agrees with the first character string in the title designation area 1 (the judgment of S408 is made in the affirmative), it is judged whether a character string is recorded in the originator designation area 1 (S409).

[0052] If a character string is recorded in the originator designation area 1 (the judgment of S409 is made in the affirmative), the character string representing the originator of the received mail message is compared with the second character string in the originator designation area 1 (S410). If the character string representing the originator of the received mail message agrees with the second character string in the originator designation area (the judgment of S410 is made in the affirmative), it is judged that both the title and originator's address of the received mail message agree with the stored ones. The contents of the received mail message are displayed on the second display device 107. Moreover, the notifying means 113 notifies the user of the fact that the mail message has been terminated (S411).

[0053] The contents of a received mail message to be displayed on the second display device 107 are represented by the data in the second predetermined division of the received mail message. The data in the second predetermined division of the received mail message is, for example, data containing at least the text of the received mail message. Otherwise, the data in the second predetermined division of the received mail message may be data containing not only the text of the received mail message but also the character string representing the title thereof, the character string representing the originator thereof, and the reception time thereof.

[0054] Although the contents of a received mail message are displayed on the second display device 107 at S411, the ability of the second display device 107 to present information may be limited in terms of the number of characters. In this case, the contents of a received mail message may be displayed while being automatically scrolled laterally or automatically scrolled page by page under the control of the control unit 103.

[0055] If it is judged at S407 that the first character string is not recorded in the title designation area 1 (the judgment of S407 is made in the negative), control is passed to S410. If it is judged at S410 that the character string representing the originator of the received mail message agrees with the second character string in the originator designation area 1 (the judgment of S410 is made in the affirmative), the contents of the received mail message are displayed on the second display device 107 as mentioned above. Moreover, the notifying means 113 notifies the user of the fact that the mail message has been terminated (S411).

[0056] Moreover, after it is judged at S408 that the character string representing the title of the received mail message agrees with the first character string in the title designation area 1 (the judgment of S408 is made in the affirmative), if it is judged at S409 that no data is recorded in the originator designation area 1 (the judgment of S409 is made in the negative), control is passed to S411.

[0057] In short, in the portable terminal device according to the first embodiment of the present invention, if one of the first character string and second character string is recorded in the pair of a title designation area and an originator designation area, it is judged whether a character string that is contained in the data in the first predetermined division of a received mail message and that should be compared with one of the first and second character strings agrees with the one of the first and second character strings. Namely, if the one of the first and second character strings is the first character string, the character string representing the title of the received mail message is the character string that should be compared with the one of the first and second character strings. In contrast, if the one of the first and second character strings is the second character string, the character string representing the originator of the received mail message is the character string that should be compared with the one of the first and second character strings. If the character strings agree with each other, the contents of the received mail message are displayed on the second display device 107.

[0058] If it is judged at S406 that a character string is recorded in neither the title designation area 1 nor the originator designation area 1 (the judgment of S406 is made in the negative), or if it is judged at S408 or S410 that the result of comparison signifies disagreement, it is judged whether n=N (where N denotes the number of pairs of character strings that can be stored in the designated character string storage device 110) is met (S412). If n=N is not met (the judgement of S412 is made in the negative), n is incremented by one, or n is updated to n+1 (S413). Control is then passed to the sequence of S406 to S410. In other words, the sequence of S406 to S410 is performed sequentially on the N pairs of character strings stored in the designated character string storage device 110 until the judgement of S409 is made in the negative or the judgment of S410 is made in the affirmative.

[0059] If it is judged at S412 that n=N is met (the judgement of S412 is made in the affirmative), it is judged that the title or originator of a received mail message disagrees with the data stored in the designated character string storage device 110. In this case, the contents of the received mail message are not displayed on the second display device 107. Instead, “New Mail Terminated” signifying that a mail message has been received is displayed and the fact that a mail message has been terminated is notified (S414).

[0060] If it is judged at S403 that the terminal is left open (the judgment of S403 is made in the negative), “New Mail Terminated” is displayed on the first display device 105. The notifying means 113 notifies the user of the fact that the mail message has been received (S415). At this time, nothing is displayed on the second display device 107.

[0061] As mentioned above, in the portable terminal device according to the first embodiment of the present invention, the character string representing the title of a received mail message and the character string representing the originator thereof are compared with the first character string and second character string that are entered in advance by the user. If the character strings agree with the first and second character strings respectively, the contents of the received mail message are displayed on the second display device 107. Consequently, the user can effectively check information he/she wants to check with the terminal device closed without the necessity of performing any special maneuver.

[0062] According to the first embodiment of the present invention, the portable terminal device selects information, which the user wants to read, and displays it. Compared with when the contents of all mail messages received are displayed, power consumption required for the displaying can be suppressed. Eventually, the shortening of the service life of a battery can be minimized.

[0063] Next, a portable terminal device in accordance with the second embodiment of the present invention will be described in conjunction with the drawings. FIG. 5 is a block diagram showing the configuration of the portable terminal device in accordance with the second embodiment of the present invention. The same reference numerals are assigned to components identical to those shown in FIG. 2. Incidentally, the portable terminal device in accordance with the second embodiment of the present invention has the appearance shown in FIG. 1A and FIG. 1B. Since the appearance has already been described, reiteration is omitted.

[0064] In the portable terminal device according to the first embodiment of the present invention, a received mail message designated or selected using the title of the received mail message and the originator's address thereof is displayed on the second display device 107. In contrast, in the portable terminal device according to the second embodiment of the present invention, a character string enclosed with tags TITLE and /TITLE (hereinafter generically title tags) contained in data created based on the Hypertext Markup Language (HTML) received by the terminal device is checked in order to judge whether a character string, which is enclosed with tags BODY and /BODY (hereinafter generically body tags) and contained in the HTML data, should be displayed as the contents of the HTML data on the second display means.

[0065] Referring to FIG. 5, the portable terminal device having a folding structure in accordance with the second embodiment of the present invention includes an antenna 101, a wireless device 102, a control unit 503, a first driver 104, a first display device 105, a second driver 106, a second display device 107, a memory 108, an HTML information analyzing unit 509, a designated character string storage device 510, a comparing means 511, an open/close detecting unit 112, a notifying means 113, an operator panel 114, and a timer means 515.

[0066] The control unit 503 has an information acquisition program 503-1. The control unit 503 runs the information acquisition program 503-1 to download an HTML file over a wireless network, and stores the film in the memory 108. Moreover, the control unit 503 controls the presentations of the first display device 105 and second display device 107 using the first driver 104 and second driver 106. Furthermore, when the control unit 503 acquires an HTML file, the control unit 503 controls the notifying means 113 to notify the user of the terminal of the fact that acquisition of the HTML file is completed.

[0067] According to the information acquisition program 503-1, an HTML file stored in a predetermined information distribution server is downloaded. Specifically, every time the timer means 515 gives a notification, the terminal is connected to the information distribution server, which provides an information distribution service for the terminal, over a wireless network in order to download an HTML file from the information distribution server. The information distribution server is located with a Uniform Resource Locator (URL) written in advance in the program.

[0068] At regular intervals of a time specified in the information acquisition program 503-1 of the control unit 503, the timer means 515 notifies the control unit 503 of the fact that the timer means has counted up a time. A character string the user has entered by maneuvering the operator panel 114 is stored in the designated character string storage device 510.

[0069] The HTML information analyzing unit 509 cuts out a title character string from an HTML file acquired according to the information acquisition program 503-1. The comparing means 511 compares the title character string cut out by the HTML information analyzing unit 509 with a character string stored in the designated character string storage device 510. The comparing means 511 then transfers the result of the comparison (agreement or disagreement) to the control unit 503.

[0070] The other components, that is, antenna 101, wireless device 102, first driver 104, first display device 105, second driver 106, second display device 107, memory 108, open/close detecting unit 112, notifying means 113, and operator panel 114 are identical to those shown in FIG. 2. The description of the components will therefore be omitted.

[0071] FIG. 6 shows an example of the structure of the designated character string storage device 510 shown in FIG. 5. Referring to FIG. 6, a character string written by the right-hand side of title designation area n (where n denotes 1 to N that is a positive integer) expresses stored data. Data to be recorded in the title designation area is a character string the user enters in advance by maneuvering the operator panel 114, and is equivalent to a title character string. Up to N character strings can be stored in the designated character string storage device 110. If no character string is recorded in a certain title designation area, information indicating the absence of a character string is recorded.

[0072] The user uses the operator panel 114 to enter a character string equivalent to a title character string of an HTML file whose contents the user wants to be displayed on the second display device 107 when the terminal device downloads the HTML file. The character string is processed by the control unit 503 and then stored in the designated character string storage device 510.

[0073] Next, the actions of the portable terminal device in accordance with the second embodiment of the present invention will be described in conjunction with the drawings. FIG. 7 is a flowchart describing the actions of the portable terminal device shown in FIG. 5.

[0074] Referring to FIG. 7, the timer means 515 notifies the control unit 503 of the fact that the timer means has counted up a predefined time (S701). The information acquisition program 503-1 is then activated (S702). The information distribution server is accessed while being located with the URL specified in advance in the information acquisition program 503-1 (S703). An HTML file stored in the information distribution server is then downloaded and stored in the memory 108 (S704).

[0075] The control unit 503 judges from the result of detection provided by the open/close detecting unit 112 whether the terminal is closed or open (S705). If the terminal is closed (the judgment of S705 is made in the affirmative), the HTML information analyzing unit 509 analyzes the acquired HTML file and cuts out a title character string enclosed with title tags (S706).

[0076] The control unit 503 receives the cut out title character string from the HTML information analyzing unit 509. The comparing means 511 then compares the title character string of the downloaded HTML file successively with the character strings recorded in the title designation areas 1 to N in the designated character string storage device 510 (S707).

[0077] If the title character string agrees with any character string recorded in a certain title designation area (the judgment of S707 is made in the affirmative), at least the character string enclosed with the body tags and contained in the HTML file is displayed on the second display device 107 as the contents of the HTML file (S708). At S708, in addition to the character string enclosed with the body tags and contained in the HTML file, the title character string may be displayed on the second display device 107.

[0078] Concurrently with the display of the character string on the second display device 107, the notifying means 113 gives a download completion notifying sound which signifies that the HTML file has been downloaded (S709).

[0079] If it is judged at S705 that the terminal is open, a presentation signifying that the HTML file has been downloaded is displayed on the first display device 105. In addition, the notifying means 113 gives the download completion notifying sound (S711).

[0080] If it is judged at S707 that a character string agreeing with the title character string is not stored in the designated character string storage device 510, a presentation signifying that the HTML file has been downloaded is displayed on the second display device 107 because the terminal is closed. Moreover, the notifying means 113 gives the download completion notifying sound (S710).

[0081] As mentioned above, in the portable terminal device according to the second embodiment of the present invention, even when not only mail message data but also an HTML file is acquired automatically with the folding terminal closed, only designated information the user wants to read can be displayed on the second display device 107. At this time, the user need not perform a special maneuver of opening the terminal so that the acquire HTML file can be displayed.

[0082] Obviously, numerous additional modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
