| PURPOSE:To obtain a key input part having an excellent characteristics, by inserting an elastic metallic thin plate on which plural key inputting movable contacts are formed, into a frame of an electronic apparatus made of an insulating high polymer. CONSTITUTION:A metallic thin plate 1 is formed by etching, pressing, etc., from a metallic material abounding in elasticity, such as phosphor bronze, stainless steel, etc. Plural semi-spherical dome parts 1a are formed toward the upper direction, on a key input part of this thin plate 1, and a recessed part 1b which projects downward on the contrary is formed in the center part of the dome part 1a, namely, the top part, respectively. This recessed part 1b constitutes a contact part of a key movable contact. On the other hand, as for a frame 2, when ABS resin, styrol resin, etc. are used as its material, the thin plate 1 is insert molded by injection molding. In this way, it is possible to obtain a key input part which decreases the number of parts, is assembled easily and is excellent in its operability. | ||||||

| 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. | ||||||

| Disclosed is keypad circuitry operable to detect a pressed key while reducing electromagnetic interference (EMI). The keypad circuitry is operable to reduce EMI in two ways: a) reducing the voltage swing occurring at the row circuitry and column circuitry of the keypad, and b) reducing the number of signal transitions by restricting the signal transitions to occurring at the column and row corresponding to a pressed key. By limiting signal transitions to occurring only at the row and column corresponding to a pressed key, fewer signal transitions occur, and thus, less EMI is produced. Additionally, reduced voltage swings at the row circuitry and column circuitry results in reduced EMI. | ||||||
