  The memory 44 described above stores first correspondence data in which different operation contents are associated with each first input key 14 included in the plurality of first input keys 14. The memory 44 has the same operation contents associated with the first input keys 14 included in the plurality of first input keys 14 that are adjacent to each other in the housing 2. The second correspondence data is stored.

  The first correspondence data associates the first input key 14 (position information of the first input key 14 shown in FIG. 4A) with the character assigned to each of the plurality of first input keys 14. The key assignment table (see FIG. 4B). The first correspondence data of the present invention is not limited to the key assignment table shown in FIG. 4B, and may be another key assignment table.

  The second correspondence data is a key assignment table in which the same numbers, symbols, and functions are associated with the first input keys 14 adjacent to each other among the plurality of first input keys 14 (FIG. 5A). FIG. 6 (a)).

  The key assignment table shown in FIG. 5A includes position information (X1, Y1) (first input key 14 on which the letter “Q” shown in FIG. 4A is printed) and position information (X1, Y2). (First input key 14 printed with character “W” shown in FIG. 4A) and position information (X1, Y3) (first input printed with character “E” shown in FIG. 4A) A number “1” is assigned to each of the keys 14). Here, numbers and symbols are assigned to the first input keys 14 as shown in FIG. The key assignment table shown in FIG. 5A is used when the telephone function is used.

Further, the key assignment table shown in FIG. 6A includes position information (X1, Y1) (first input key 14 on which the character “Q” shown in FIG. 4A is printed) and position information (X1, Y1). Y2) (first input key 14 printed with the letter “W” shown in FIG. 4A) and position information (X1, Y3) (first printed with the letter “E” shown in FIG. 4A) The function of moving the cursor (a graphic indicating the current input position on the display unit 21) in the upper left direction is assigned to each of the 1 input key 14). Here, functions are assigned to the first input keys 14 as shown in FIG. The key assignment table shown in FIG. 6A is used when a browser application is used.
The second correspondence data of the present invention is not limited to the key assignment table shown in FIGS. 5A and 6A, and may be another key assignment table.

  The control unit 45 selects one of the first correspondence data and the second correspondence data stored in the memory 44 according to a predetermined condition, and based on the selected first correspondence data or second correspondence data. When the operation on the first input key 14 is detected by the operation detection unit 16, the operation content is executed.

  That is, when the control unit 45 selects the first correspondence data (the key assignment table shown in FIG. 4B) according to a predetermined condition, for example, the first row and the first column shown in FIG. When an operation of the first input key 14 (the first input key 14 with “Q” printed on the front surface) is detected by the operation detection unit 16, the operation is performed by referring to the memory 44. The character “Q” corresponding to the position information (X1, Y1) of the key 14 is read, the character “Q” is input to the editor application, and the editor application in which the character “Q” is input is displayed on the display unit 21.

  Further, when the control unit 45 selects the second correspondence data (the key assignment table shown in FIG. 5A) according to a predetermined condition, for example, the first row and the first column shown in FIG. When the operation of the first input key 14 is detected, by referring to the memory 44, the number “1” corresponding to the position information (X1, Y1) of the operated first input key 14 is read, and the number “1” is displayed on the display unit 21. Further, when a telephone call key is operated in a state where a plurality of numbers are displayed on the display unit 21, the control unit 45 makes a telephone call using the numbers displayed on the display unit 21 as telephone numbers.

  Further, when the control unit 45 selects the second correspondence data (the key assignment table shown in FIG. 6A) according to a predetermined condition, for example, the first row and the first column shown in FIG. When the operation of the first input key 14 is detected, the function corresponding to the position information (X1, Y1) of the operated first input key 14 (function to move the cursor to the upper left) is referred to the memory 44. ).

  When any one of the plurality of second correspondence data (the key assignment table shown in FIG. 5A and the key assignment table shown in FIG. 6A) is selected, the second correspondence data is activated. What is necessary is just to select according to the application, function, etc. which are carried out. That is, the control unit 45 may select the key assignment table shown in FIG. 5 (a) when the telephone function is used, and the key assignment table shown in FIG. 6 (a) when the browser application is activated. Just choose.

  By the way, when the second correspondence data is selected by the control unit 45, when a plurality of first input keys 14 to which the same operation content is assigned are pressed by a single operation by the user, the first input is performed. The operation content for each key 14 is executed. For example, when the user wants to display the number “1” on the display unit 21, a plurality of first input keys 14 (position information (X1, Y1)) to which the number “1” is assigned by a single operation by the user. When the position information (X1, Y2) first input key 14) is pressed, the display unit 21 displays the number “11”. For this reason, when selecting the second correspondence data, the control unit 45 can receive the operation of the first input key 14 to which the same operation content is assigned within a predetermined period only once. It is possible to prevent an operation content not intended by the user of the telephone 1 from being executed. For example, even when a plurality of first input keys to which the number “1” is assigned are pressed within a predetermined period, the number “1” is displayed on the display unit 21.

  As described above, the mobile phone 1 is assigned the same operation content to the adjacent first input key 14 when the second corresponding data is selected according to a predetermined condition. Therefore, since the mobile phone 1 executes the operation content when any of the first input keys 14 to which the same operation content is assigned is operated, the operability of the first input key 14 is improved, It is possible to suppress erroneous operations.

  In addition, the control unit 45 selects either one of the first correspondence data and the second correspondence data stored in the memory 44 according to the operation on the instruction operation unit 12 detected by the operation detection unit 16, and Based on the selected first correspondence data or second correspondence data, the operation content is executed when an operation on the first input key 14 is detected by the operation detection unit 16.

  The instruction operation unit 12 may be, for example, a switch or button for selecting one of the first correspondence data and the second correspondence data. In this case, the operation detection unit 16 detects switch switching or button pressing as the operation of the instruction operation unit 12. The control unit 45 selects the first correspondence data and the second correspondence data based on the switch switching or button press detected by the operation detection unit 16. For example, the control unit 45 selects the first corresponding data when the button is not pressed, and selects the second corresponding data when the button is pressed.

  Therefore, the mobile phone 1 selects one of the first corresponding data and the second corresponding data stored in the memory 44 in accordance with the operation on the instruction operation unit 12 detected by the operation detection unit 16. Assignment of characters, numbers, and the like to the first input key 14 can be switched according to the user's intention.

  Further, when the temperature detection unit 47 detects a temperature equal to or lower than a predetermined temperature, the control unit 45 selects the second correspondence data stored in the memory 44, and based on the selected second correspondence data, The operation content may be executed when an operation on the first input key 14 is detected by the operation detection unit 16.

  The predetermined temperature is, for example, a temperature of about 5 ° C. If it becomes 5 degrees C or less temperature, the user of the mobile telephone 1 may wear a glove. Alternatively, it may be impossible to operate as if the hand is gripping. When the first input key 14 is operated while wearing gloves, the possibility that the plurality of adjacent first input keys 14 are pressed almost simultaneously in one operation is increased. When the hand is gripping, the first input key 14 adjacent to the first input key 14 intended to be operated may be operated. In this case, when the first corresponding data is selected, the plurality of first input keys 14 are pressed by one operation, or the first input key 14 adjacent to the first input key 14 intended to be operated is pressed. If it does, for example, a plurality of characters may be displayed on the display unit 21 or an unintended character may be displayed, and the user may feel uncomfortable. For this reason, if the temperature detected by the temperature detection unit 47 is equal to or lower than the predetermined temperature, the control unit 45 selects the second correspondence data, and the same number or the like is assigned in one operation. Even when the first input key 14 is pressed and the first input key 14 is operated while wearing a glove or a hand bite, for example, one character is displayed on the display unit 21. The user can input a desired character. The predetermined temperature is not limited to the above example (5 ° C.), and may be another temperature.

  Therefore, the mobile phone 1 selects the second correspondence data stored in the memory 44 when the temperature detection unit 47 detects a temperature equal to or lower than the predetermined temperature, and thus the user of the mobile phone 1 does not intend. Execution of the operation content can be suppressed.

Note that a number corresponding to the second correspondence data may be printed on the first input key by using a paint whose character is displayed (raised) when the temperature is equal to or lower than a predetermined temperature.
Thus, when the first correspondence data is selected (when the temperature detection unit 47 does not detect a temperature equal to or lower than the predetermined temperature), characters are displayed on the surface of the first input key 14, while the second correspondence data is displayed. When data is selected (when the temperature detection unit 47 detects a temperature equal to or lower than a predetermined temperature), letters and numbers are displayed on the surface of the first input key 14. Here, when characters and numbers are displayed on the surface of the first input key 14, the characters and the numbers may be displayed in different colors.

FIG. 7 is an external perspective view of the mobile phone 1 to which the case member 2d is attached.

  The case member 2d is provided with a second input key 17 corresponding to the first input key 14 corresponding to the second correspondence data and assigned with the same operation content. When any one of the plurality of second input keys 17 is pressed, one or more first input keys 14 among the first input keys 14 corresponding to the pressed second input keys 17 are pressed. Is done. For example, when the upper left second input key 17a among the plural (at least one) second input keys 17 shown in FIG. 7 is pressed, the second input key 17a is arranged below the pressed second input key 17a. Among the first input keys 14 (in the case shown in FIG. 4A, the position information (X1, Y1), the position information (X1, Y2), and the position information (X1, Y3) first input keys 14)) Any one of the first input keys 14 is pressed by the second input key 17a.

  Therefore, when the case member 2d is attached to the housing 2, the cellular phone 1 operates the second input key 17 to move the first input key 14 corresponding to the operated second input key 17 to the mobile phone 1. Can be pressed.

  When the case member 2d is attached to the housing 2, the control unit 45 selects the second correspondence data stored in the memory 44, and the first input key based on the selected second correspondence data. The operation content is executed when the operation detection unit 16 detects an operation on 14.

  FIG. 8 is a cross-sectional view of the case member 2d. In the case shown in FIG. 8A, the case member 2d is provided with a projection 2f at the end of the back surface thereof. When the case member 2d is attached to the mobile phone 1, the protrusion 2f arranged on the case member 2d is a switch (instruction operation unit 12: not shown in FIG. 8A) arranged on the mobile phone 1. ). In this case, the control unit 45 detects that the switch has been pressed by the operation detection unit 16, and selects the second correspondence data.

  Further, in the case shown in FIG. 8B, the case member 2d is provided with a protrusion 2f on the back surface thereof. When the case member 2d is attached to the cellular phone 1, the protrusion 2f disposed on the case member 2d is not shown in the first input key (FIG. 8B) as the instruction operation unit 12 of the cellular phone 1. Z)). In this case, a function for executing the operation content is not assigned to the first input key pressed by the protrusion 2f, but a function for selecting the second correspondence data is assigned. And the control part 45 detects that the 1st input key as the instruction | indication operation part 12 was pressed down by the operation detection part 16, and selects 2nd corresponding | compatible data.

  Accordingly, since the cellular phone 1 selects the second correspondence data when the case member 2d is attached to the housing 2, the mobile phone 1 assigns characters, numbers, and the like to the first input key 14 according to the attachment of the case member 2d. Can be switched.

FIG. 9 is a rear external perspective view of the mobile phone 1 when the case member 2d also serves as the battery lid 2c.
