Abstract
Abstract A card-like electronic apparatus comprises a core member an electronic assembly, an upper cover, and a lower cover. The core member includes a frame having an accommodation section for accommodating the electronic assembly, and a thick portion protruding from the frame. The electronic assembly is arranged in the accommodation section and includes a printed circuit board having a plurality of stational key contacts, an IC chip, an electronically-driven display unit, and a thin flat battery. The upper cover is arranged on one surface of said electronic assembly and includes a pressure-deformable sheet having movable key contacts aligned with said stational key contacts, key indicia aligned with the movable key contacts, and a display window aligned with the display unit. The lower cover includes a supporting plate, arranged over another surface of said electronic assembly, having a cutaway portion in which said thick portion is fitted, and which has high rigidity. An embossment is formed in such a way that each of the upper cover, the thick portion of the core member, and the lower cover has one surface recessed and other surface protruding. A magnetic stripe portion is provided on the lower cover.
