| 摘要 | PURPOSE:To decrease remarkably the number of parts, and to simplify the assembling process, by inserting an elastic metallic thin plate into a frame of an electronic apparatus made of an insulating high polymer and forming a key inputting movable contact on this thin plate. CONSTITUTION:For instance, in case when a thermoplastic material such as ABS resin, styrol resin, etc. is used for a material of a frame 2, a metallic thin plate 1 is inserted molded by injection molding. Also, the uppermost part of a dome part 1a is on the almost same face as the upper face of the frame 2, the side of a recessed part 1b forms an exposed face, too, the upper and lower faces of a connecting part 1c are also exposed, and a key inputting movable contact is contituted. These connecting parts 1c are cut and separated after insert molding, and electric conduction between key blocks and between outside frames is cut off. Also, a surface sheet 4 consists of transparent polyvinyl chloride, etc. having moderate flexibility, and is loaded on a printed substrate 3 together with a resistance, a capacitor, etc. | ||||||
