<P>PROBLEM TO BE SOLVED: To provide a push button device for voice communication apparatus which not only can reduce the number of components without reducing the number of switches that can be turned on/off but can also be made with a simple structure. <P>SOLUTION: A push button 10, which is constituted by one rectangular frame-shaped panel member molded from elastic synthetic resin, is provided with supporting ribs 17, 17... arranged on respective sides. The push button 10 is attached to a front face of a front case 2 with the four positions serving as a fulcrum. Further, operation projections 15, 15... are respectively provided at the four corners on a rear face of the push button 10 such that they protrude rearward. Operation windows 22, 22... through which the operation projections 15, 15... can be inserted are opened on the front case 2. When one of the four corners of the push button 10 is pushed, the corner is bent and pushed in so that the operation projection 15 provided at the corner enters a body case via the operation window 22 to thereby turn on/off a corresponding switch 11 on a circuit board 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
