The function of the main control unit 20 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs. The main control unit 20 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 28.

  The table storage unit 24 stores the types of image information displayed in the area A of the touch screen 12 (hereinafter referred to as “display mode”) and operation buttons corresponding to the display mode displayed in the area B of the touch screen 12. Stores the table. FIG. 3 shows an example of the table. In FIG. 3, for example, when the display mode displayed in the area A is “normal mode”, the operation buttons displayed in the area B are “clear / memo”, “mail”, “Web”, “call”, “ "End story", "Quick". When the type of image information other than the display mode shown in FIG. 3 is displayed in the area A, the main control unit 20 displays an operation button corresponding to the “normal mode” in the area B of the touch screen 12.

  FIG. 4 shows a display example on the touch screen 12. The image information display area at the top of the touch screen 12 is referred to as area A, and the operation button display area at the bottom is referred to as area B. The main control unit 20 determines the display mode from the image information displayed in the area A of the touch screen 12, and the operation button pattern corresponding to the display mode is stored in the table storage unit 24 as shown in FIG.

As shown in FIG. 4A, the area B of the touch screen 12 has a relationship between the display space of the area B and the ease of pressing the buttons. In addition, not all the operation buttons corresponding to the display mode are displayed, for example, only three buttons are displayed.

  Therefore, the main control unit 20 first displays the three operation buttons surrounded by the “initial display” frame shown in FIG. The other selectable operation buttons are not displayed in the area B and are hidden and cannot be seen, and are displayed by the user scrolling the area B left and right as shown in FIGS. Is done. For example, every time the user scrolls once from right to left, for example, three operation buttons are displayed in the order shown in FIG. For example, when the display mode is “standby mode”, it is assumed that the operation buttons currently displayed in the area B are “address book”, “menu”, and “app” that are initially displayed, and the user moves the area B from the right. When scrolling once to the left, the operation buttons “Clear / Memo”, “Mail”, and “Web” that are right next to “App” in the order of operation buttons shown in FIG. Is displayed. When the user further scrolls the area B once from the right to the left, operation buttons for “call”, “end call”, and “quick” are displayed.

  In addition, a part of the operation buttons are displayed on the left or right of the area B as shown in a of FIG. 4B so that the user can know that other operation buttons exist and can be scrolled. May be. Further, when the user continues to scroll the area B in either the left or right direction, the operation button display in the area B may be a repeated continuous display that can be displayed repeatedly by returning to the “initial display” operation button. Assuming that the buttons are displayed in a line as shown in FIG. 3, when the operation button in "Initial display" is displayed, it cannot be scrolled from left to right because it is at the left end, and the operation button at the right end is displayed. Sometimes it may be a single line display that scrolling from right to left is not possible.

  FIG. 5 shows a display example of the touch screen 12 corresponding to the table of FIG. When the image information display in the area A is the standby screen ((A) in FIG. 5), the display mode is “standby mode” in FIG. 3, and therefore the operation button “address book” for initial display in the standby mode is displayed in the area B. , “Menu”, “App” are displayed. When the area B is scrolled left and right, other operation buttons corresponding to the “standby mode” are displayed in order.

  When the “address book” button in the area B is pressed when the image information is displayed in FIG. 5A, the area A transitions to the address book display ((B) in FIG. 5). Since the corresponding display mode at this time is “transmission mode” in FIG. 3, the operation buttons “clear / memo”, “transmission”, and “end call” of the initial display in the transmission mode are displayed in the area B. When the area B is scrolled left and right, other operation buttons corresponding to the “call mode” are displayed in order.

  When the “transmission” button in the area B is pressed when the image information is displayed in FIG. 5B, the area A becomes a transmission image display (FIG. 5C). Since the type of the image information in the area A at this time does not correspond to the display mode shown in FIG. 3, the operation button corresponding to the “normal mode” is displayed in the area B.

When a certain image is displayed in the area A of the touch screen 12 in the mobile phone 1, the main control unit 20 determines a display mode from the image information (step S11). Next, the main control unit 20 refers to the table shown in FIG. 3 stored in the table storage unit 24 and calls an operation button pattern corresponding to the display mode displayed in the area A (step S13). Next, the main control unit 20 displays three operation buttons “initial display” shown in FIG. 3 in the region B of the touch screen 12 among the operation buttons called in step S13 (step S15). When there are four or more operation button patterns corresponding to the display mode displayed in step S11 (“Yes” in step S17), the main control unit 20 selects another operation button that has been called by a scroll operation in the region B. Display in area B (step S19).

  The operation buttons displayed in the area B can be input from the operation key 15 by opening the mobile phone. However, when it is troublesome to open and operate the mobile phone for a few operations, Even in the closed state, an operation button having the same function as the operation key 15 is displayed on the touch screen 12, and a touch operation is possible.

  As shown in FIG. 7, the operation buttons displayed in the area B are stored in the table storage unit 24 in the form of function buttons and numeric buttons, and are switched and displayed not only in the horizontal scroll but also in the vertical scroll. You may be made to do. In FIG. 7A, function buttons are assigned to the first row, number buttons are assigned to the second row, and the user selects a function by scrolling left and right in the first row and then displays the second row by scrolling up and down. can do. In FIG. 7B, the function button and the numeric button are switched by scrolling up and down, and the function button and the numeric button are switched by scrolling left and right. For example, the user can scroll left and right in a row of desired function buttons to display and select numeric buttons. FIG. 7C shows three operation buttons “Clear / Memo”, “Mail”, “Web” in the first row, and three operation buttons “Address”, “OK”, “App” in the second row. Number buttons and “Clear / Memo”, “Dial”, “End” operation buttons are assigned to the third row, and the user can select by scrolling up and down. From FIG. 7, it is possible to further select operation buttons by scrolling not only to the left and right but also to the top and bottom.

  Next, the operation when there is an incoming call in the mobile phone 1 of the present embodiment will be described with reference to FIG.

  The mobile phone 1 is in a standby state, and the touch operation is effective on the entire screen of the touch screen 12 (step S101). When the communication control unit 26 receives an incoming call (“Yes” in step S103), the touch screen control unit 22 locks the touch operation for the area A of the touch screen 12 and enables only the scroll operation for the area B (step S105). ). At the same time, the main control unit 20 displays an arrow button, which is an initial display of the operation buttons corresponding to the “incoming mode” in FIG. 3, in the area B (step S106).

  Next, when the user performs a scroll operation on the area B in the direction of the arrow of the arrow button (“Yes” in step S107), the touch screen control unit 22 detects the scroll operation in the area B and moves the entire touch screen 12 over. The lock is released and the touch operation is enabled (step S109). The main control unit 20 displays “clear / memo”, “call”, and “end call” operation buttons in the area B.

  As a result, when the mobile phone is placed in a bag or the like and an incoming call is received, the touch screen in the area A is locked and only the scroll operation in the area B is enabled. Even if the display is erroneously pressed, no response operation is performed, and malfunction can be prevented.
