[0104] In the font retrieval system according to the present embodiment, retrieval keys are determined for each retrieval item. The retrieval key(s) is(are) entered, to find a font(s) conforming to the entered retrieval key(s).

[0105] The retrieval items include partial image retrieval, font name retrieval, kind (of text) retrieval, use (of text) retrieval, automatic management retrieval, and favorite retrieval.

[0106] The partial image retrieval is for designating an image representing a portion (a part) (a partial image) constituting a character to find a font (a sub-font) from the designated partial image. In the partial image retrieval, “Fude-oroshi”, “Tome”, “Hidari-harai”, “Migi-harai”, “Hidari-hane” and “Migi-hane” are set as the retrieval items, i.e., as the portions (parts of) (partial image of) the character (especially, a Chinese character=Kanji).

[0107] A user selects one or a plurality of desired retrieval item(s) out of the portions (partial images) “Fude-oroshi”, “Tome”, “Hidari-harai”, “Migi-harai”, “Hidari-hane” and “Migi-hane”. The portions (partial images) “Fude-oroshi”, “Tome”, “Hidari-harai”, “Migi-harai”, “Hidari-hane” and “Migi-hane” respectively represent the ways of writing the portions constituting the character (Chinese character), as shown in FIGS. 43 to 46.

[0108] As shown in FIG. 6, a plurality of portions having different shapes which are respectively represented by a plurality of fonts (a plurality kinds of sub-fonts) are set as retrieval keys for each of the retrieval items, i.e., “Fude-oroshi”, “Tome”, “Hidari-harai”, “Migi-harai”, “Hidari-hane” and “Migi-hane”. For example, Fude-oroshi 1, Fude-oroshi 2, Fude-oroshi 3, Fude-oroshi 4 and so on are set as retrieval keys for the retrieval item “Fude-oroshi”, Tome 1, Tome 2, Tome 3, Tome 4 and so on are set as retrieval keys for the retrieval item “Tome”. The user designates one or a plurality of the retrieval keys.

[0109] As to the font name retrieval, various main font names such as “Mincho”, “Kaisho”, “Kyokasho”, “Gyosho”, “Gothic”, “Maru-gothic”, “Comic” and “Hop” are set as retrieval keys. The user designates one of the retrieval keys.

[0110] As to the kind-of-text retrieval (kind retrieval), a kind of the sentence or text which is entered by the user is used as a retrieval key. The kinds for the sentence include “Article”, “Report”, “Letter”, “Advertisement or Leaflet”, “Magazine”, “Manual”, etc. The user designates one of the retrieval keys.

[0111] As to the use-of-text retrieval (use retrieval), uses for the sentence clause or phrase or text in one document are used as retrieval keys. The uses for the sentence (text) in one document, for example, “Title”, “Text”, “Emphasis”, “Note”, “Headline”, “Subhead”, “Comment” and “Itemization” are designated as retrieval keys.

[0112] The kind (of text) retrieval and the user (of text) retrieval are altogether referred as a text retrieval.

[0113] The automatic management retrieval includes retrieval based on the number of times of use, retrieval based on the number of entered characters, and retrieval based on the number of links.

[0114] The retrieval based on the number of times of use is for retrieving a font on the basis of the number of times of use of the font (sub-font). Examples include descending order retrieval for retrieving fonts in descending order of the numbers of times of use of the fonts and ascending order retrieval for retrieving fonts in ascending order of the numbers of times of use of the fonts. The descending order and the ascending order are kinds of the retrieval keys. The retrieval based on the number of entered characters is for retrieving, for each type of font (sub-font), the font on the basis of the number of characters entered with the font. The retrieval based on the number of links is for retrieving a font on the basis of the number of retrieval keys linked to the font (the number of retrieval keys related to the font). The descending order and the ascending order are used as the retrieval keys in the retrieval based on the number of entered characters and in the retrieval based on the number of links.

[0115] The favorite retrieval is for previously registering user's favorite fonts and retrieving a font on the basis of the registration.

[0116] FIG. 7 illustrates an example of a font link table (font link data) stored in the HD of the client computer 1. An unique font ID (Identification) number N is assigned to each font (sub-font). Stored in the font link table in correlation with the font ID number N are the font name, the install location where the font data is stored, the file name of the font data, the number of times of use of the font, the number of characters entered with the font, the number of the retrieval keys (number of links) and the retrieval keys (which may be represented by a retrieval key numbers described later) linked to (associated with) the font. With regard to the font data stored in the HD of the client computer 1, the install location is represented by a path (file name), and with regard to the font data stored in the HD of the server 30, the install location is represented by a URL (Uniform Resource Locator).

[0117] FIG. 8 illustrates an example of a font link table (font link data) stored in the HD of the server 30. The items included in the table are the same as those shown in FIG. 7.

[0118] FIG. 9 illustrates an example of a retrieval key link table (retrieval key link data) stored in the HD of the client computer 1. FIG. 10 shows an example of a retrieval key link table stored in the HD of the server 30.

[0119] The retrieval key link table is used for finding a font or fonts (sub-font(s)) using the above mentioned retrieval keys (exclusive of the descending order and the ascending order) and relates the retrieval key to the fonts (sub-fonts) associated with (linked to) the retrieval key. A unique retrieval key (ID) number M is assigned to the retrieval key. Stored in the retrieval key link table, in correspondence with the retrieval key number M, are the retrieval key (name) and the sub-font names (which may be represented by the font ID number) (linked fonts) linked to the retrieval key.

[0176] (3) Font Retrieval

[0177] FIGS. 18 and 19 are flow charts showing the procedure for font retrieval processing. The font retrieval processing is for retrieving fonts concerning font data stored in the hard disk for the client computer 1.

[0178] Prior to the font retrieval, at least one retrieval key 25 with respect to at least one retrieval item has been set using the above-mentioned font selection window. The font retrieval is a processing for finding a sub-font (or sub-fonts) each of which is linked to all the set retrieval keys or key. In order to perform the font retrieval processing, at least one of (or both of) the font link table (FIG. 7) and the retrieval key kink table (FIG. 9) is used.

[0179] The previous result of retrieval (area A92) is cleared prior to the font retrieval processing (step 41). An internal font number (counter) N₁for designating the font ID number N is reset-(step 42). The internal font number N₁is incremented (step 43). The sub-font name FN having a font ID number N equal to the incremented internal font number N₁is read out of the font link table in the hard disk for the client computer 1 (step 44).

[0180] An internal retrieval key number M₁designating the retrieval key number M is reset (step 45). The internal retrieval key number M₁is incremented (step 46). A retrieval key KM having a retrieval key number M equal to the incremented internal retrieval key number M₁is read out from the retrieval key link table (step 47).

[0181] It is judged whether or not the retrieval key KM read out has been set (step 48).

[0182] When the retrieval key KM has been set (YES at step 48), it is judged on the basis of the font link table whether the retrieval key KM and the N₁-th font name FN are linked to each other (step 49). If they are linked (YES at step 49), it is checked whether the N₁-th font name FN read out is linked to all set retrieval keys, incrementing the internal retrieval key number M₁(step 51, steps 46-50).

[0183] If the N₁-th font name FN read out is linked to all the set retrieval keys, a font represented by the N₁-th font name FN coincides (matches) with all of the retrieval keys set by the user. The N₁-th font name FN is added to (displayed on) the result of retrieval (the retrieval result area A92) (step 52).

[0184] If the N₁-th font name FN read out is not linked to one of all the set retrieval keys (NO at step 50), the font represented by the N₁-th font name FN does not coincide with all of the retrieval keys set by the user. Therefore, the N₁-th font name FN is not added to the results of retrieval, and the subsequent font data is read out by incrementing the internal font number N₁(No at step 53, and steps 43 and 44).

[0185] When check as to whether all the font data stored in the font link table in the hard disk are linked to the set retrieval keys is terminated (YES at step 53), an automatic management key A (a retrieval key set in the automatic management area A87) is read out (step 54). When the automatic management key A has been set (YES at step 55), the results of retrieval (sub-font names) are sorted on the basis of the set automatic management key A (in the set order of descending order or ascending order) (step 56). The sorted results of retrieval are displayed in the retrieval result display area A92 (step 57). If the automatic management key A has not been set, the results of retrieval (a list of the sub-font names) are displayed in the retrieval result display area A92 without being sorted (step 57).

[0186] FIGS. 20 to 25 illustrate an example of the font selection window displayed on the display screen of the display device 14 in the client computer 1.

[0187] Referring to the drawings, how a font is retrieved will be specifically described.

[0188] First, a retrieval key shall be set such that a kind of a text to be entered (or having been entered) is set to “Advertisement, Leaflet”, and the sentence or text to be entered (or having been entered) is used for a use “Emphasis” (FIG. 20). It goes without saying that these retrieval keys are set by pulling down the kind retrieval setting area A83 and the use retrieval setting area A84, as described above.

[0189] The retrieval area A104 is clicked by the user, so that font retrieval processing is performed. A font name or font names which are linked to all the set retrieval keys are found, referring to the font link table or the retrieved key link table (the processing from the step 41 shown in FIG. 18 to the step 53 shown in FIG. 19). Here, no retrieval key is set in the automatic management area A87, so that the results of retrieval are displayed in the retrieval result area A92 without being sorted (the processing at steps 54, 55 and 57 shown in FIG. 19) (see FIG. 21).

[0190] Characters represented by a font corresponding to a font name displayed in the uppermost part of the retrieval result area A92 is displayed in the selected font preview area A62 (the kinds of displayed characters are predetermined). In the example shown in FIG. 21, “Kaisho 3” is displayed as a font name in the uppermost part of the retrieval result area A92, so that characters represented by the font “Kaisho 3” are displayed in the selected font preview area A62.

[0191] Furthermore, partial images represented by a desired font (or fonts) are respectively set in the “Hidari-harai” area A73 and the “Migi-harai” area A74 in the partial image retrieval area A70 in order to narrow the results of retrieval down (see FIG. 22). The partial image represented by a desired font is also set by designating a partial image in the partial image list window A110 appearing by clicking each of the “CHANGE” buttons corresponding to the “Hidari-harai” area A73 and the “Migi-harai” area A74, as described above (FIG. 13).

[0192] When the retrieval area A104 is clicked again by the user, font retrieval processing is performed again, adding the newly set partial image retrieval keys. The results of retrieval are displayed in the retrieval result area A92. Characters represented by a font of a font name displayed in the uppermost part of the retrieval result area A92 is displayed in the selected font preview area A62 (see FIG. 23). In the example shown in FIG. 23, “Maru-gothic 3” is displayed as a font name in the uppermost part of the retrieval result area A92, so that characters represented by the font “Maru-gothic 3” is displayed in the selected font preview area A62.

[0193] In order to rearrange the results of retrieval in ascending order of the numbers of entered characters in the past, the number of entered characters and the ascending order shall be respectively set in the automatic management area A87 and the sort area A88 in the automatic management information area A86 (see FIG. 24).

[0194] When the retrieval area A104 is clicked by the user, the font names are rearranged in ascending order of the numbers of characters entered with fonts represented by the font names, and are displayed in the retrieval result area A92 (see FIG. 25). In the example shown in FIG. 25, the font for which the number of entered characters in the past is smallest is “Comic 2”, so that characters represented by the font “Comic 2” is displayed in the selected font preview area A62.

[0195] FIGS. 26ato 26cillustrate a part of the font selection window.

[0196] In the present embodiment, preview characters displayed in the selected font preview area A62 can be also changed.

[0197] As shown in FIG. 26a, when the preview character area A90 is pulled down by the user, a pull-down list is displayed. Desired preview characters are is selected by the user on the pull-down list displayed as shown in FIG. 26b. Here, “0123456789” is selected as the preview characters. As shown in FIG. 26c, the selected preview characters are displayed with a font found by the retrieval in the selected font preview area A62.

[0198] FIGS. 27ato 27cillustrate a part of the font selection window.

[0199] In the present embodiment, preview characters displayed in the selected font preview area A62 can be changed into characters desired by the user.

[0200] As shown in FIG. 27a, a character display window of the preview character area A90 is clicked by the user. Consequently, there arises a state where a preview character can be entered. Characters displayed in the preview character area A90 is erased, to enter characters desired by the user from the keyboard 7. As shown in FIG. 27b, the entered characters are displayed in the preview character area A90. By pressing a line feed key in the keyboard 7 or clicking an area other than the preview character area A90 using the mouse 8, the entered characters become effective. As shown in FIG. 27c, the entered characters are displayed in the selected font preview area A62.

[0201] FIGS. 28 to 31 illustrate an example of the font selection window.

[0202] In the present embodiment, characters represented by two different fonts can be simultaneously displayed in the font selection window, i.e., in the temporary font preview area A61 and the selected font preview area A62.

[0203] As described above, the characters represented by the font found by the font retrieval is displayed in the selected font preview area A62 (see FIG. 28). Characters represented by a font displayed in the uppermost part of the retrieval result area A92 by the font retrieval, for example, the font “Kaisho 3” in the example shown in FIG. 28 has been displayed in the selected font preview area A62. In a state where “Kaisho 3” in the retrieval result area A92 is selected, when the temporary setting area A103 is clicked by the user, “Kaisho 3” is set as a temporary font.

[0204] The selected font “Kaisho 3” is displayed in the temporary font display area A91, and the characters represented by the font “Kaisho 3” is displayed in the temporary font preview area A61 (see FIG. 29).

[0205] A font to be compared with the font of the characters displayed in the temporary font preview area A61 is then selected by the user. Here, the font “Gothic 5” and the font “Kaisho 3” shall be compared with each other.

[0206] The font “Gothic 5” is selected by the user out of the font names displayed in the retrieval result area A92 (see FIG. 30). Characters represented by the font “Gothic 5” newly selected is displayed in the selected font preview area A62.

[0207] It is possible to directly compare the characters represented by the font “Kaisho 3” displayed in the temporary font preview area A61 and the characters represented by the font “Gothic 5” displayed in the selected font preview area A62 with each other.

[0208] When the user judges that the font “Kaisho 3” displayed in the temporary font preview area A61 is used by comparing the characters represented by the font “Kaisho 3” displayed in the temporary font preview area A61 and the characters represented by the font “Gothic 5” displayed in the selected font preview area A62 with each other, the temporary font area A91 is clicked by the user. Consequently, the font displayed in the temporary font area A91 is brought into a selected state (see FIG. 31). Thereafter, the OK area A106 is clicked by the user, so that “Kaisho 3”, displayed in the temporary font preview area A61 is selected as a font to be used.

[0209] FIGS. 32aand 32billustrate a part of the font selection window.

[0210] Although in the above-mentioned example, the results of retrieval displayed in the retrieval result area A92 are expressed by font names, the results of retrieval displayed in the retrieval result area A92 can be also changed into and expressed by characters represented by retrieved fonts.

[0211] When the font name display designation button A93 in the font selection window is selected, a list of font names representing retrieved fonts is displayed in the retrieval result area A92 (FIG. 32a). When the preview designation button A94 in the font selection window is selected, a list of characters represented by the retrieved fonts is displayed in the retrieval result area A92 (FIG. 32b). It is possible to find at a glance how the retrieved fonts are.

[0212] FIGS. 33ato 33cillustrate an example of a single character font list display window appearing on the display screen of the display device 14 in the client computer 1.

[0213] When the list display area A102 in the font selection window is clicked by the user, a single character font list display window A120, as shown in FIG. 33a, appears on the display screen of the display device 14.

[0214] A list of all fonts representing a single character is displayed in the single character font list display window A120 on the basis of all font data stored in the hard disk.

[0215] The single character font list display window A120 includes a character entry window A121, a change area A122, and a cancel area A123.

[0216] When the single character displayed in the single character font list display window A120 is changed, the character entry window A121 is clicked by the user, as shown in FIG. 33b. After the character displayed in the character entry window A121 is erased, a desired character is entered from the keyboard 7.

[0217] When the change area A122 is clicked by the user after the desired character is entered in the character entry window A121, a list of the fonts representing the entered single character is displayed on the basis of the font data stored in the hard disk (FIG. 33c).

[0218] It is possible to confirm at a glance all the fonts stored in the hard disk.

[0219] FIG. 34aillustrates a part of the font selection window, and FIGS. 34bto 35dillustrate an example of a favorite edit window appearing in the font selection window.

[0220] In the present embodiment, it is possible to register a font desired by the user as a favorite font. When the favorite font is added or deleted, the favorite edit window is displayed on the display screen of the display device 14.

[0221] Referring to FIG. 34a, a desired font name is selected out of the results of retrieval whose list is displayed in the retrieval result area A92 in the font selection window. Thereafter, when the favorite addition area A101 is clicked by the user, the favorite edit window appears, as shown in FIG. 34b, on the display screen of the display device 14.

[0222] The favorite edit window includes a favorite list area A131 where a list of user's favorite fonts is displayed (the fonts are displayed in the order of descending priorities of favorites from the top), a selected font area (a font name selected by the user is displayed) A132, an addition area A133, areas A134 and A135 clicked by the user when the priorities of favorites are changed, a delete area A136, an OK area A137, and a cancel area A138.

[0223] When the addition area A133 is clicked by the user, the selected font displayed in the selected font area A132 is added as a favorite font, and is displayed in the uppermost part of the favorite list display area A131 (FIG. 34c). In an example shown in FIG. 34c, “Mincho 3” is selected as the selected font, so that “Mincho 3” is displayed in the uppermost part of the favorite list display area A131.

[0224] When the priorities of favorites displayed in the favorite list display area A131 are changed, the font whose priority is to be changed is selected by the user (FIG. 34d). When the priority is raised, the upward area A134 is clicked by the user, so that the priority is set to a desired priority (see FIG. 35a). When the priority is lowered, the downward area A135 is clicked by the user.

[0225] When there is a font to be deleted from the favorite list display area A131, the font to be deleted is selected out of the fonts displayed in the favorite list display area A131, and the delete area A136 is clicked by the user (see FIG. 35b).

[0226] If the contents of the edited favorite are acceptable, the OK area A137 is clicked by the user (FIG. 35c). When the contents of the edited favorite are cancelled, the cancel area A138 is clicked by the user (FIG. 35d).

[0227] (4) Font Link Processing

[0228] FIG. 36 is a flow chart showing the procedure for processing for linking a retrieval key and font.

[0229] When the retrieval key and the font are linked to each other, the font F to be linked to the retrieval key is selected and read out of the hard disk for the client computer 1 (step 91).

[0230] An internal retrieval key number M₁is reset (step 92). The internal retrieval key number M₁is then incremented (step 93).

[0231] A retrieval key KM having a retrieval key number M equal to the internal retrieval key number M₁is read out (step 94). It is judged whether or not the retrieval key KM read out and selected font F are linked to each other (step 95). If they are not linked to each other (NO at step 95), it is judged whether or not the font F is linked to a retrieval key KM having a retrieval key number M equal to the subsequent internal retrieval key number M₁, incrementing the internal retrieval key number M₁(step 100, step 93, 94, 95). When both are linked to each other, it is judged whether or not the retrieval key KM and the font F have already been linked to each other (step 96).

[0232] If they have already been linked to each other (YES at step 97), they need not be newly linked to each other. Therefore, it is judged whether or not the font F is linked to the retrieval key KM having the retrieval key number M equal to the subsequent internal retrieval key number M₁, incrementing the internal retrieval key number M₁(step 100, step 93, 94, 95). If they have not linked to each other yet (NO at step 97), the retrieval key KM and the font data F are newly linked to each other (step 98). Specifically, a retrieval key is added to the corresponding font in the font link table (see FIGS. 7 and 8). Further, the number of links to the font data is incremented (step 99). The font is added to the corresponding to the retrieval key in the retrieval key link table (FIGS. 9 and 10).

[0233] The processing from the step 93 to the step 99 is repeated until likes to all the retrieval keys are terminated (step 100).

[0234] FIGS. 37 to 46 illustrate an example of the font selection window.

[0235] Referring to FIGS. 37 to 46, description is made of a link between font and a retrieval key.

[0236] In order to display a font in the retrieval result area A92, the number of links and the ascending order are respectively set in the automatic management area A87 and the sort area A88 in the automatic management information area A86 (FIG. 37).

[0237] When the retrieval setting area A104 is clicked by the user, font names representing all the fonts stored in the hard disk for the client computer 1 are displayed in the retrieval result area A92 in ascending order of the numbers of links (see FIG. 38).

[0238] The name of a font to be linked is then selected from the font names displayed in the retrieval result area A92. Here, “Mincho 3” shall be linked. The font “Mincho 3” is selected by the user (see FIG. 39).

[0239] In order to establish a link, the registered mode setting button A96 is clicked, to enter a registration mode (FIG. 40).

[0240] A retrieval key to be linked to the font “Mincho 3” is then set. The font retrieval area A80 is pulled down, so that “Mincho” is set as a retrieval key to be linked to the font “Mincho 3” (FIG. 41). Further, “Report” and “Text” are set as retrieval keys to be linked to the font “Mincho 3” (FIG. 42). It goes without saying that the retrieval keys, that is, “Report” and “Text” are also selected, after pull-down lists are respectively displayed by pulling down the kind retrieval setting area A83 and the use retrieval setting area A84, from the displayed pull-down lists.

[0241] A desired partial image is then set as partial image retrieval (FIG. 43).

[0242] When all the retrieval keys have been set, the registration command setting area A105 is clicked by the user, so that the link to the font “Mincho 3” is terminated (FIG. 44).

[0243] Furthermore, when the retrieval key is linked, the retrieval key is set. For example, when a link to the font “Mincho 3” is established using kind and use of a text, that is, “Article” and “Itemization” as retrieval keys, “Article” and “Itemization” are set in the areas A83 and A84 (FIG. 45). When the registration command setting area A105 is clicked by the user, the retrieval keys “Article” and “Itemization” are linked to the font “Mincho 3” (FIG. 46).

[0244] (5) Font Retrieval in Client Computer and Server

[0245] Although the above-mentioned font retrieval is performed with respect to the font stored in the hard disk for the client computer 1, it is also possible to take font stored in the hard disk for the server 30 as an object of font retrieval by setting a destination (a client or server) of font retrieval.

[0246] FIG. 47 illustrates an example of the font selection window. FIGS. 48ato 49cillustrate a part of the font selection window.

[0247] The font selection window shown in FIG. 47 includes a font retrieval destination setting area A130. The font retrieval destination setting area A130 includes a font retrieval destination area A131 and a file name setting area A132.

[0248] The font retrieval destination setting area A130 is utilized by the user when a destination of retrieval of font is set. It is possible to determine using the font retrieval destination area A131 whether the font stored in the hard disk for the client computer 1 is taken as an object of retrieval or the hard disk for the server 30 which can communicate with the client computer 1 is taken as an object of retrieval. Further, it is possible to set a file name to be an object of retrieval using the file name setting area A132.

[0249] The destination of font retrieval is set using the font retrieval destination area A131 in the following manner.

[0250] The font retrieval destination setting area A130 is pulled down. Consequently, a pull-down list appears (FIG. 48a). A name representing a desired destination of retrieval is selected from the pull-down list (here, an URL name is selected; FIG. 48b). When the selection is terminated, the selected name is displayed in a display window of the font retrieval destination area A131 (FIG. 48c).

[0251] It is possible to also set a desired destination of retrieval that does not exist in the pull-down list by entry from the user. The display window of the font retrieval destination area A131 is clicked by the user (FIG. 48d). Consequently, a text is allowed to be entered using the keyboard 7. A desired name (a path name, etc.) is entered by the user (FIGS. 48eand 48f).

[0252] The file name setting area A132 is pulled down by the user. Consequently, a pull-down list appears (FIG. 49a). A desired file name is selected from the pull-down list by the user, so that a file name at a destination of retrieval of font is set (FIGS. 49band 49c). Font is retrieved in a file having the set file name.

[0253] FIGS. 50 and 51 are flow charts showing the procedure for processing in a case where font retrieval is also performed with respect to the font stored in the hard disk for the server 30 in addition to the font stored in the hard disk for the client computer 1.

[0254] A retrieval destination key K is first read out by the user (step 61). If the retrieval destination key K is not entered from the user (YES at step 62), font retrieval based on the font data stored in the hard disk for the server 30 is not performed. Therefore, the font retrieval is performed in the client computer 1 in the procedure for processing shown in FIGS. 18 and 19, as described above (step 64). The result of retrieval obtained by the font retrieval is read out (step 65), and is displayed in the retrieval result display area A92 in the font selection window (step 72).

[0255] When the retrieval destination key K is entered from the user, it is judged whether it is a file path (step 63) or a URL (step 66).

[0256] If the retrieval destination key K is the file path, this indicates that file retrieval based on the font stored in the hard disk for the client computer 1 is performed, so that the font retrieval is performed in the client computer 1 (step 64). If the retrieval destination key K is the URL, this indicates that font retrieval based on the font stored in the hard disk for the server 30 is performed, so that data representing the retrieval key set in the font selection window is transmitted from the client computer 1 to the server 30 (step 67).

[0257] When data representing the retrieval key transmitted from the client computer 1 is received in the server 30 (step 81), font retrieval processing is performed on the basis of the font stored in the hard disk for the server 30 on the basis of the received retrieval key (step 82). The font retrieval processing in the server 30 is also performed in the same manner as the font retrieval processing in the client computer 1 shown in FIGS. 18 and 19.

[0258] When the font retrieval processing is terminated in the server 30, data representing the result of retrieval is transmitted from the server 30 to the client computer 1 (steps 83 and 84).

[0259] On the other hand, also in the client computer 1, the font retrieval is performed on the basis of the retrieval conditions set in the font selection window (step 68). The result obtained by the retrieval is read out (step 69).

[0260] Both a font obtained as a result of the font retrieval in the client computer 1 and a font obtained and received as a result of the font retrieval in the server 30 (step 70) are obtained as the results of retrieval (step 71). The results of retrieval are displayed in the retrieval result area A92 in the font selection window displayed in the display device 14 in the client computer 1 (step 72). It is possible to also retrieve the font stored in the server 30 which can communicate with the client computer 1.

[0261] For example, a font name “FJ-Comic” (=the result of client retrieval Sc) shall be obtained as a result of the font retrieval in the client computer 1, and font names “FJ-Mincho, FJ-Gothic, FJ-Comic” (=the results of server retrieval Ss) shall be obtained as a result of the font retrieval in the server 30. As the results of retrieval, “FJ-Mincho, FJ-Gothic, FJ-Comic” (=the results of retrieval Sc U Ss) are displayed.

[0262] (6) Sequential Font Conversion

[0263] FIG. 52 illustrates a text which is being entered using the keyboard 7 in the client computer 1 and operations at that time.

[0264] In the present embodiment, the font of a part of the text which is being entered can be changed into a font different from the font of the text which is being entered.

[0265] In the first step during entry of the text shown in FIG. 52, “” is entered, and a font is set to “Mincho” in the text entered in the first step.

[0266] In the second step, “” is entered (an underlined part indicates an undetermined state). In the second step, a Kanji conversion key in the keyboard 7 is pressed, so that the text part in the undetermined state is converted into Kanji (or Katakana).

[0267] In the third step, the Kanji conversion key in the keyboard 7 is pressed again, so that Kanji (or Katakana) in the text part in the undetermined state is determined. In the third step, Kanji is determined as “” in the text part in the undetermined state.

[0268] In the fourth step, a font conversion key in the keyboard 7 is pressed, so that the font of the text part in the undetermined state is converted. As the font conversion key is pressed, the font of the text part in the undetermined state is converted and displayed.

[0269] In the fifth step, when a font determination key in the keyboard 7 is pressed, the font of the text part in the undetermined state is determined. Therefore, Kanji conversion and font conversion are terminated, so that an underline indicating the undetermined state disappears, as shown in the sixth step.

[0270] The font which changes every time the font conversion key is pressed will conform to the order of favorites, as described above.

[0271] Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
