<P>PROBLEM TO BE SOLVED: To provide a hinge means in which a hinge section provided in a base of a panel plate is given a margin and the panel is supported through the hinge section, and the front side faces of the overlapped panel plates are therefore arranged flush with each other. <P>SOLUTION: A plurality of stacked panel plates are placed in a single-action key part of a control panel and a hinge hole 19a of the hinge section 19 corresponding to a pivotal support shaft 16 with respect to the panel plates 10 to 12 provided turnably with respect to the pivotal support shaft 16 is structured to have a greater margin at its lower part with respect to the pivotal support shaft 16. The hinge hole 19a is constituted to have a greater margin at its upper and lower parts corresponding to the overlapped position with respect to the other panel plates, so that a gap is formed in the overlapped panel faces in accordance with the position of the stacked panel plates to accurately obtain sensing information of key switches. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
