Description of the Preferred Embodiments
Next, an electronic device such as a wireless selective call receiver of the present invention will be described with reference to the attached drawings.
First, the wireless selective call receiver according to the first embodiment of the present invention will be described.
FIG. 1 is a block diagram illustrating the structure of the wireless selective call receiver according to the first embodiment of the present invention. Referring to FIG. 1, the wireless selective call receiver is composed of an antenna (ANT) 1, a wireless section 2, a control section 3, an ID-ROM 4, an informing section 5, a LCD driver 6, a LCD 7 with a display screen, a RAM 8, a ROM 9, an operation section including a switch (SW) 10 as an operation element, and a detecting section 11 including a timer (not shown).
In the wireless selective call receiver in the first embodiment, a radio signal from a paging system is received by the antenna (ANT) 1 and is sent to the wireless section 2. The wireless section 2 demodulates the wireless signal into base-band data. The demodulated data is sent to the control section 3.
The control section 3 compares, in a normal mode, a self selection call number which is stored in the ID-ROM 4 and a selection call number which is contained in the received demodulated data. When these numbers are coincident with each other, the control section 3 controls the informing section 5 to inform it. When a message is contained in the received data, the control section 3 stores the message in the RAM 8 as a message memory. Also, the control section 3 drives the LCD driver 6 such that the message is displayed on the display screen of the LCD 7. A program which defines the operation of the whole of wireless selective call receiver with the display section is stored in the ROM 9.
The operation section of the wireless selective call receiver with the display section is equipped with the switch 10 as an operation element. The switch 10 is used for both the confirmation of the message which has been received and the selection of a menu. The detecting section 11 is inserted between the control section 3 and the switch 10. The detecting section 11 always monitors a time interval of a pushing or depressing of the switch 10, i.e., a pushing continued time interval, and the number of times of the pushing of the switch 10. The detecting section 11 outputs a mode change signal to the control section 3 when a pushing of the switch 10 is detected for a time interval longer than a predetermined time interval, e.g., one second in this example, or a double click within the predetermined time interval. In response to such a pushing operation, the control section 3 changes the mode from the normal mode to a menu selection mode in response to the mode change signal. Additionally, the control section 3 drives the LCD driver 6 such that the LCD 7 displays a menu.
Additionally, the detecting section 11 outputs an item designation signal to the control section 3 when a pushing of the switch 10 is detected in the menu selection mode while a menu is displayed. The control section 3 selects and sets one of items of the menu in response to the item designation signal.
For example, the confirmation of the message in the normal mode is performed in response to the pushing operation of the switch 10. In other words, the pushing operation time interval of the switch 10 is measured by the timer (not shown) of the detecting section 11. If the pushing operation time interval is equal to or less than 1 second, the detecting section 11 sends to the control section 3 a signal instructing control section 3 to display the message. In the wireless selective call receiver, since it is important to confirm the received message, a single push of the switch 10 within one second is used to set the action for the message confirmation.
On the other hand, pushing the switch 10 for a time interval longer than one second is allocated to the menu selection. Alternatively, twice pushing of the switch 10 within one second (this is referred to as a double-click) may be allocated to this menu selection. Hereinafter, it is supposed that the pushing operation of the switch 10 for a time interval longer than one second is allocated to the menu selection for simplification. It should be noted that one of the pushing operations of this switch 10 which is easy to operate for a user should be stored previously in the ID-ROM 4. When it is detected that the switch 11 has been pushed for a time interval longer than one second, the detecting section 11 sends a mode change signal to the control section 3 indicating that the mode is changed from the normal mode to the menu selection mode.
Next, the operation of the wireless selective call receiver will be described.
FIG. 2 is a schematic diagram of the state change in response to the operation of the switch 10 in case of the selection of a menu in the first embodiment.
Referring to FIG. 2, in the procedure (1), when the switch 10 is operated for a time interval longer than one second (or a double-click operation), the control section 3 changes the mode of the wireless selective call receiver from a clock display mode as a normal mode to a menu selection mode. The control section 3 sends information of menu setting screens one after another to the LCD driver 6 with a predetermined time interval, and each menu setting screen is displayed one after another on the LCD 7. That is, each menu setting screen is automatically scrolled one item by one item. At this time, the control section 3 notifies such a detecting section 11, that the menu setting screens are being automatically scrolled.
In the procedure (2), when the switch 10 is pushed in the above state, the detecting section 11 informs the pushing operation of the switch 10 to the control section 3 regardless of the time interval of the pushing operation of the switch 10. That is, the detecting section 11 outputs an item designation signal to the control section 3. In response to the item designation signal, the control section 3 selects one of items of the menu which are being automatically displayed during the scroll, and sets the selected item.
In the last procedure (3), the control section 3 determines one of the items of the selected menu based on the pushing operation of the switch 10 when a desired function setting screen is displayed while the items of the selected menu are automatically scrolled.
If the selected item in the procedure (2) corresponds to a submenu, the submenu is also displayed while items of the submenu are being automatically scrolled.
FIGS. 3A and 3B are diagrams illustrating a specific example of the menu selection in the first embodiment.
Referring to FIG. 3A, in the first embodiment, the clock displaying state of the screen A is displayed on the LCD 7 in a normal mode. The normal mode is set when there is no pushing operation of the switch 10 and when the wireless selective call receiver is in a time interval other than a time interval immediately after a message is received.
In case of selection of a menu, the user pushes the switch 10 for a time interval longer than one second (as described above, there may be a case that the switch 10 is double clicked). At that time, an alarm setting screen of the screen B is displayed for one second as a first item of a first menu. Then, the display screen is automatically changed to a timer setting screen of the screen C as a second item of the first menu. This display screen is also displayed for one second. After that, an alert setting screen of the screen D is automatically displayed as a third item of the first menu. As mentioned above, in the menu selection mode, the screens corresponding to the first to third items of the first menu are automatically scrolled, as long as there is not any item designation signal generated based on the pushing operation of the switch 10.
When the switch 10 is pushed in the state in which the last alert setting screen of the screen D is displayed as shown in FIG. 3A, the alert setting menu is selected. Referring to FIG. 3B, the screens from the screen E to the screen J corresponding to items of the selected alert setting menu are shown to describe a method of setting the details of the alert setting menu.
The item "Sound On" is shown in the screen E and the item "Sound Off" is shown in the screen F. The item "Sound On" means that the informing operation is carried out by use of sounding a speaker. On the other hand, the item "Sound Off" means that the informing operation is carried out by use of vibration of a vibrator due to vibration of a motor.
When the alert setting screen is displayed as the last screen D of FIG. 3A, and the switch 10 is pushed the alert setting is selected. At that time, the item "Sound On" of the screen E and the item "Sound Off" of the screen F are automatically and alternately displayed with the time interval of one second. In this case, if the switch 10 is pushed in the state in which the item "Sound On" of the screen E is displayed, the content of the alert setting is determined to be the item "Sound On".
Next, an item "Beep" of a screen G and an item "Musical" of the screen H are automatically and alternately displayed with the time interval of one second. The item "Beep" means that the speaker sounds. The item "Musical" means that the speaker sounds a simple melody. When the switch 10 is pushed in the state in which the item "Beep" of the screen G is displayed, a content of the alert setting is determined to be the item "Beep".
Then, an item "Single" of the screen I and an item "Dual" of the screen J are automatically and alternately displayed with the time interval of one second. The item "Single" means that the speaker sounds with a single frequency. The item "Dual" means that the speaker sounds alternately with two different frequencies. When the switch 10 is pushed in the state in which the item "Single" of the screen I is displayed, the item "Single" is selected as a content of the alert setting.
After this, the control returns to the waiting state (clock display) by the pushing operation of the switch 10.
Overall, the items "Sound On", "Beep" and "Single" are selected by the pushing operation of the single switch only 10, so that the contents of the alert setting menu as one of the menus can be determined.
Next, the wireless selective call receiver according to the second embodiment of the present invention will be described. The structure of the wireless selective call receiver according to the second embodiment is same as that of the first embodiment. Therefore, the description will be omitted.
In the first embodiment, the whole screen portion of the display screen is used for the selection of a menu or selection of an item of the menu. However, in the wireless selective call receiver in the second embodiment, an upper half area of the display screen of the LCD 7 is used for selection of a menu or selection of an item of the menu, as shown in FIG. 4. When the first item of a menu is displayed in the upper half area of a display screen, the following second item is displayed in the lower half of the display screen. After one second, the second item is displayed in the upper half area of the display screen and the third item is displayed in the lower half area of the display screen. Thus, the screens corresponding to the items of the menu are automatically scrolled with one second interval. In this embodiment, since the next item can be confirmed, there is more conveniences for the user.
Also, a plurality of items of a menu are displayed on a display screen and the plurality of items may be sequentially highlighted with a predetermined time interval to distinguish the active state, instead of the automatic scroll. When the switch is pushed as described above in the state in which one of the items is highlighted, the item may be selected.
As described above, according to the wireless selective call receiver with the display unit of the present invention, the pushing operation of the switch is performed for a time interval longer than a predetermined time interval for the selection of one of items of a menu. Alternatively, a twice pushing operation of the switch within a predetermined time interval, i.e., a double click is performed for the selection of the item of the menu. During the selection of the item of the menu, the items of the menu are automatically scrolled with a predetermined time interval. Thus, a desired one of the items of the menu can be selected or set in response to the pushing operation of the switch in the state in which the desired item of the menu is displayed. Thus, the menu setting operation is improved.
Also, the present invention has one of the features in that the wireless selective call receiver with the display unit can be provided to give the user convenient menu selection, using only a single switch. Therefore, the wireless selective call receiver of the present invention can be implemented with hardware this is small in volume. Also, the wireless selective call receiver with the display unit can be manufactured to have a small size and complex functions so as to match to the needs in the market. Further, the wireless selective call receiver with the display unit can be manufactured with a low cost because the number of electric parts associated with the switch can be reduced.
