<P>PROBLEM TO BE SOLVED: To enable an operation body, which is a key top, to be always lifted/lowered in a stable posture, in a pressing-type input device arranged on a keyboard device, etc. <P>SOLUTION: A guide member 5 which moves in a Y-direction and an operation body 6 which is lifted/lowered are arranged, and a switch mechanism is pushed by the operation body 6. A first inclined pressing part 77b, a second inclined pressing part 73b and inclined controlling parts 72b are formed on the operation body 6. A rising angle θ2 of the first inclined pressing part 77b is greater than a rising angle θ1 of the inclined controlling parts 72b. The operation body 6 and the guide member 5 which are biased in the lifting direction are abutted with each other at abutting points (a) and (b) so that the looseness between the operation body 6 and the guide member 5 is prevented. When the operation body 6 is pushed, the guide member 5 is pushed in a Y2-direction by the first inclined pressing part 77b and the second inclined pressing part 73b so that the operation body 6 is pulled in a Z2-direction by the inclined controlling parts 72b provided at a plurality of positions. Consequently, the operation body 6 is stably lowered in a horizontal posture. <P>COPYRIGHT: (C)2012,JPO&INPIT |
