Kind Code:
A1
Abstract:
The invention addresses the problem of providing a pushbutton switch which can give a clear operation feeling to a person who performs a push operation, and in which the sharpness, accuracy, and brightness of an image output from a display can be increased as compared with those in the related art. A button 11 accepts a pressing operation. Lenses 15a to 15d focus and project an image output from a display D on a diffuser plate 12 on the top surface of the button 11. A holding member 14 holds the lenses 15a to 15d. Further, the holding member 14 is configured of a combination of a spacer 41 having a rib 411 fitted to a rib receiver 152c of the lens arranged on the top surface side among the lenses 15a to 15d, a spacer 42 having a rib receiver 151b fitted to a part of the lens arranged on the external display side, and an aperture film 43 sandwiched between the spacer 41 and the spacer 42. As a result, the above problem is resolved.
