It is preferable that these settings can be arbitrarily set by the user by creating items in a menu list displayed by operating the menu button 42. The same applies when a digital image is sent by operating the return button 32. In the present embodiment, two digital images are displayed on the substantially half of the liquid crystal panel 12, but the number of digital images to be displayed is not limited to this, and may be one or two or more.

  As described above, when the touch panel sheet 72 is pressed while a plurality of digital images are displayed on the liquid crystal panel 12 (hereinafter referred to as a normal display mode) and one specific digital image is selected, the selected digital image is displayed. As shown in FIG. 7, the screen shifts to an enlarged display mode for displaying the entire screen size of the contracted position and the expanded position.

  In this enlarged display mode, the screen size is determined according to the detection result of the limit switch 78, the digital image to be displayed is compared with the screen size, and the displayed digital image is rotated in the direction in which it is maximized. To the full screen size. For example, in FIG. 7A, a rectangular digital image P9 is displayed over the entire screen size corresponding to the contracted position. When the movable portion 18 is moved from this state to the extended position, the digital image P9 cannot be enlarged any more even if the digital image P9 remains in the same orientation, although the screen size is expanded. Therefore, by rotating the digital image P9 by 90 ° as shown in FIG. 7B, the digital image P9 can be further enlarged and displayed with the expansion of the screen size. By rotating the digital image in this way, each screen size can be used effectively. Note that pressing the enlarged digital image returns the display mode from the enlarged display mode to the normal display mode. Further, when the touch panel sheet 72 is pressed as described above, it is preferable to notify the user that the touch panel sheet 72 has been pressed by, for example, generating an operation sound from the speaker 40.
