<p>PURPOSE:To prevent a body from touching an input/output terminal part exposed on the surface of a main card system directly by forming a fold in the main card system so that the terminals are covered by the main card system when the system is folded. CONSTITUTION:A main card system has a fold 1a running vertically in almost the center in the lateral width direction of the system, and an input/output terminal part 2 of a circuit is incorporated in the system 1 at one side of the fold 1a, while terminals 4a to 4d of protecting elements 3a to 3d are arranged at a symmetrical position with the fold 1a. When the main card system 1 is bent in two parts at the fold 1a, the terminals 4a to 4d of the protecting elements 3a to 3d become connected to each terminal of the input/output terminal part 2. The main card system 1, when folded, has the protecting elements 3a to 3d connected to each terminal Vcc, RST, CLK, I/O or the input/output terminal part 2 through protecting terminals 4a to 4d. Consequently, the protecting elements 3d, 3a are connected to an input terminal 12 and a power supply terminal 13, for example. Therefore, the input/output terminal part 2 exposed on the surface of the main card system 1 is shielded from outside by the main card system 1, so that a direct contact with a body is prevented.</p> |
