1. An operation unit comprising:
a touch panel that senses a press; a button plate disposed above the touch panel, and having a plurality of push buttons, each of which protrudes on a side opposite to a side where the touch panel is disposed; a light guide plate disposed between the touch panel and the button plate; and a light emission pattern disposed on a surface of the light guide plate that forms an image by emitted light, wherein the button plate is provided along a surface of the touch panel and comprises:
a base section comprising apertures at respective positions where the plurality of push buttons are formed,top surface sections, each of which constitutes corresponding one of the plurality of push buttons and serving as an operation surface,bending deformable sections, each of which connects, in a freely elastically deformable manner, a peripheral section of corresponding one of the top surface sections and an edge of corresponding one of the apertures formed in the base section, andprojections disposed on back sides of the top surface sections, wherein one or more of the projections come into contact with the surface of the touch panel at the time when any one of the top surface sections is pushed down toward the touch panel and corresponding one of the bending deformable sections is subjected to bending deformation, wherein the one or more of the projections corresponds to the one top surface section pushed down, wherein the light guide plate comprises apertures at respective positions corresponding to the plurality of push buttons, and wherein the apertures of the light guide plate are formed so as to allow passage of the projections provided to the plurality of push buttons. |
