Description

  According to the present invention, two casings can be overlapped with the display unit provided on one of them being exposed to the outside, and characters can be input while the two casings are overlapped. The present invention relates to a stackable portable terminal device.

  2. Description of the Related Art Conventionally, there has been a mobile terminal device that can display a character on a display unit such as a mobile phone by providing a display unit such as an LCD (liquid crystal display) and an operation unit (for example, Patent Literature). 1).

  Although not shown, the portable terminal device as described in Patent Document 1 has a numeric keypad for inputting numbers “1” to “9” and “0” in its operation unit. In addition to these numbers, a plurality of characters such as kana characters and alphabets are assigned to each key of the numeric keypad.

  The user can input a character to be displayed on the display unit by pressing the key a predetermined number of times in correspondence with the order of the plurality of characters assigned to each key. It has become.

  In recent years, since the types and structures of the mobile terminal devices are diversified according to the functions and applications, the numeric keypad is separated from the method of inputting characters using the numeric keypad as described in Patent Document 1. A method of inputting characters that does not use a character has also been devised. For example, as shown in FIG. 11, there is a PDA (Personal Digital Assistant) 2 that can input characters without using a numeric keypad.

  The PDA 2 does not include a numeric keypad, but includes a display unit 4 for displaying characters and the like, a jog dial 6 used for character input operations, a mode key 8, and a menu key 10. The jog dial 6 is rotated as indicated by an arrow a in the figure to select any item from a menu (not shown) displayed on the display unit 4 and pushed in as indicated by an arrow b in the figure. As a result, both operations for confirming the selected item can be performed.

  When characters are input to the display unit 4 of the PDA 2, the menu key 10 is first depressed to display a menu (not shown) on the display unit 4, and then the jog dial 6 is operated to operate the menu (not shown). A character input screen 12 as shown in FIG. 12 is displayed on the display unit 4 by selecting and confirming a character input item in FIG.

  The character input screen 12 includes an edit frame 12a, a key input frame 12b, and a conversion candidate frame 12c, and any one of these is displayed as a thick line frame as an operation target. ing. When it is desired to change the operation target displayed in the bold frame, by pressing the mode key 8, the editing frame 12a, the key input frame 12b, and the conversion candidate frame 12c are mutually connected. , Can be switched to any other in turn.

  Then, after the user sets the key input frame 12b as the operation target, the user selects and confirms the character to be input from the list of the Japanese syllabary in the key input frame 12b by operating the jog dial 6. Then, the character is displayed on the edit frame 12a. In selecting and confirming such characters, the task of selecting and confirming the line to which the character to be input belongs from the list of the Japanese syllabary and selecting and confirming the character to be input from this line. It is performed in two stages of work.

  In addition, when a character that has been converted into Kanji characters is displayed in the conversion candidate frame 12c corresponding to the character input by such an operation, the operation target is changed to the conversion candidate frame 12c by the operation of the mode key 8. The character that is appropriately converted is selected and confirmed by operating the jog dial 6 from the plurality of characters displayed in the conversion candidate frame 12c, and the character is displayed on the editing frame 12a. ing. By enabling such operations, the PDA 2 can input characters without using the numeric keypad.

  On the other hand, as a mobile terminal device different from the PDA 2, there is a stacked mobile phone 20 as shown in FIG. 13. The stackable mobile phone 20 includes a first casing 24 having a display unit 22 and a second casing 28 having a main operation unit 26. The first casing 24 and the second casing 28 are The second casing 28 is connected to each other by a connecting portion 32 around an axis perpendicular to the main operating surface 30 on which the main operating portion 26 is disposed.

  In the opened state in which the first case 24 and the second case 28 are opened at approximately 180 ° as shown in FIG. 13, the superposition type mobile phone 20 inputs characters by operating the numeric keypad 26a and the like of the main operation unit 26. Can be done.

  Although not shown in the drawings, the lap-type mobile phone 20 rotates the first housing 24 clockwise from the open state so that the first housing 24 covers the main operation unit 26. 28 can be closed on top of 28. In this closed state, the display surface 22a of the display unit 22 can be exposed to the outside, but it becomes impossible to input characters by operating the numeric keypad 26a of the main operation unit 26.

Therefore, if a sub-operation unit corresponding to the jog dial 6, mode key 8 and menu key 10 of the PDA 2 as shown in FIG. You will be able to enter.
