Specifically, for example, a user who mainly uses English may attach a hologram sheet on which key information images corresponding to input information groups such as alphanumeric characters and English-specific symbols are recorded. Can be entered. At this time, when the function registration of the input information group corresponding to the new hologram sheet has not been completed, by changing the setting of the input information group to the mobile phone 1, etc. The input information group corresponding to the key information image may be associated with the input information group on the mobile phone 1 side. Similarly, if the user mainly performs e-mail transmission, a hologram sheet on which key information images corresponding to input information groups such as pre-registered pictograms, handwritten characters, illustrations, ringtone switching, etc., may be attached, This makes it possible to input a transmission mail in a short time. Furthermore, even when the user wants to change various function information, the user can change the settings of the mobile phone 1 by attaching a hologram sheet corresponding to the changed function information and changing the settings of the mobile phone 1. The state can always be kept highly functional.
[0031]
According to the present embodiment, the notch 13a (see FIG. 1) is provided in the input display body 10 (at least the hologram sheet 13) in the portion corresponding to the outer edge of each input key 5 (the edge in the three directions). Therefore, the operability can be improved by easily following the vertical movement of each input key 5.
