<P>PROBLEM TO BE SOLVED: To provide a mobile electronics containing a case, an electronic unit housed in the case, and a conductive input/output terminal installed so as to move toward the case and accessible from exterior of the case, for achieving electrical protection of both the electronic unit and its external interface. <P>SOLUTION: In this mobile electronics, input/output terminals A, B are electrically-connected with the electronic units 72, 74 via transmission lines I/OA, I/OB to transmit electronic signal. Each of the input/output terminals A, B has a 1st or a 2nd position being decoupled/coupled from the electronic units 72, 74, respectively. The mobile electronics includes transmission gates TGA, TGB inserted on the transmission lines I/OA, I/OB, containing transmission state or non-transmission state which enables coupling or decoupling of the input/output terminals A, B with the electronic units 72, 74, respectively. Additionally, electrostatic protection elements TVSA, TVSB are inserted between the input/output terminals A, B and the transmission gates TGA, TGB. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
