<P>PROBLEM TO BE SOLVED: To provide a spring mechanism which can be fitted even at a space-limited place while characteristics intended by a designer are maintained. <P>SOLUTION: A keyboard frame 200 is fixed to a shelf plate 201 with screws 202 and 203. The keyboard frame 200 has a guide 204 erected to restrict horizontal movement of a key 300 when the key is pressed and is mounted with a stopper 205 for restricting its vertical movement. The key 300 and keyboard frame 200 are freely turnably fitted through a V-shaped leaf spring 400. At specified positions on an inside opposite surface of an opening part of the V-shaped leaf spring 400, cylindrical boss parts 401 and 402 are arranged. The boss parts 401 and 402 have screw through holes toward an outside surface of the opening part of the V-shaped leaf spring. Screws 403 and 404 are engaged with the screw holes formed in the boss parts 401 and 402, thereby the keyboard 300 and keyboard frame 200 are freely turnably attached through the V-shaped leaf spring 400. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
