The card casing 3 is centered on the hinge 12 and faces the panel 5 of the main casing 2 as shown in FIG. In the folded state, the surface only functions as a cover, but since the transmitter 13 is built in, the card casing 3 is opened around the hinge portion 12 as shown in FIG. A telephone call is made through a through hole 14 formed in the speaker 13 portion.

  According to the cellular phone device described in the above-described conventional configuration, the cellular phone device can be compact when carried and can be easily carried, but the card casing 3 is opened via the hinge 12 as shown in FIG. Since it is used in a state, it has poor stability, is easily damaged, and the portable information terminal device is placed on the ear, so that there is a problem that the display unit cannot be seen and the operation unit cannot be operated.

  In addition, there is a problem in that the main body casing 2 and the card casing 3 are increased in size during a call and the size is increased.

  Furthermore, since various methods have been proposed for conventional mobile phone devices, it is often impossible to use them at all when a terminal for a certain mobile phone device is taken outside a predetermined area. However, there is a problem that the user's own data such as a personal phone number cannot be used at all.

  The present invention solves the above-mentioned problems. The purpose of the present invention is to be able to memorize the phone number and view the LCD information while putting the body on the ear in the state of use such as a call or communication. At the same time, only necessary operation keys are arranged on the card so that it is easy to use and a compact one can be obtained during a call.
