Title: Electronic equipment
Inventor: SHINOHARA ISATO
IPC: H01H13/712
Filed: 1986-02-20
Abstract: PURPOSE:To execute the assembling of a key input part by only integrating a frame into an equipment, by adopting a structure on which a conductive layer is formed, for the lower face of an inner key formed integrally with the frame of the electronic equipment. CONSTITUTION:In a state that a key input is not executed, a key top 2d holds a neutral state by the elasticity of an arm 2e, and the inner key top 2d is in a state that the conductive material 2f of its lower face is separated from a key pattern 4a. In this state, when a key input is executed by selecting a key symbol 1c, a surface layer sheet 1 is bent, and the inner key top 2d is pushed, therefore, the arm 2e is brought to an elastic deformation, and the key top 2d descends. Accordingly, the conductive material 2f contacts the key pattern 4a, and the key input is executed. The displacement quantity of the key top 2d is determined by adjusting the thickness, length or width of the arm 2e.
