There is a problem that it takes time and effort to peel off the adhesive sheet 17 on which the display characters, which are separate parts attached to the display unit 12, are printed, and the adhesive part sticks to the peeling part after the peeling, which is very dirty.

[0006] When used again on the wall, there is a problem that the adhesive sheet 17 on which the display characters, which are separate parts to be attached to the display unit 12, are printed is not peeled off. In other words, there was a problem that it was not possible to alternately use the mobile phone in a stationary state or on a wall.

Therefore, according to the present invention, even if the main body is turned upside down, the display characters on the display section are displayed in the forward direction,
Eyes that used in wall-mounted is to provide an arrangement that can be alternately
