The tablet type 6 of the conventional type has a structure in which the screen 4 is extremely enlarged, and is a device in which the screen function is given the highest priority over portability.

  A conventional smartphone 1 is mainly provided with a screen 4 with a touch panel, a speaker 3, a microphone 5, a camera 2 and the like on the surface of the housing, and a control circuit unit (not shown), a radio circuit, a battery, and the like mounted therein. The tablet 6 is characterized by a large screen 4 and can operate a large screen with a touch panel, and can convey a large amount of information simultaneously to not only individuals but also a large number of people by its images and sounds. Some telephones are equipped with a communication device such as a loudspeaker system because they are difficult to use.

  However, since the smartphone 1 has many diverse users and places importance on portability, there is a limit to the enlargement of the screen. Especially, the elderly are inferior in visual acuity and the movement of the fingertip is dull. It is difficult to operate the touch panel on the screen. To compensate for this, a large tablet type 6 device of A4 size or B5 size is used. In order to introduce a lot of information instead of a catalog, the salesmen who carry around and carry out sales activities are more burdensome than the former.

  For this reason, the screen size is insufficient for a smartphone, and the portability is insufficient for a tablet type, resulting in a lack of consideration for the user.
