[Prior Art]

 Conventionally, an integrated circuit memory device called an IC card is mounted to increase the memory capacity of an electronic device. Such integrated circuit memory devices are roughly classified into a two-piece connector type and a one-piece connector type, depending on the method of connecting to an electronic device. The two-piece type has a structure in which the integrated circuit memory device has a built-in connector, so that the connection with the electronic device is reliable, but the thickness is larger than that of the one-piece type. The one-piece type is thinner than the two-piece type because the connection terminal is used as the printed wiring of the board, but the card body has a structure in which the aluminum panel is bonded to the resin case, so the thickness is at least about 2 mm. Will be needed. In addition, both of them have an outer shape of 54 mm x 85.6 mm, which is the same as a credit card. An electronic device housing such a large integrated circuit memory device is a display unit such as a liquid crystal display panel and a key. On the bottom surface side of the device main body in which the input section is stored, the integrated circuit memory device storage section is provided at a position aligned with the display section and the flat section.
