ABSTRACT:
The object of the present invention is to utilize a reinforcing plate formed out of a metal or a hard resin introduced into a key unit in order to overcome the weak point that conventional rubber keypads are too soft and lack shape stability, as a design element of equipment including a key unit into which the plate is incorporated.For example, a part of metal reinforcing plate4is positively exposed to a position which can be seen from the outside of key unit1, and various decorations are applied to the exposed part7so as to allow it to function as a decorated component. As a location where the reinforcing plate is exposed, there can be cited a part between each key on the key face or an annular part which encircles a plurality of key clusters. A mode may be considered in which the part of the exposed reinforcing plate4surrounds each individual key top2like a key frame, so as to substitute a key frame which has been conventionally realized by the equipment casing. The shape of the exposed part of the reinforcing plate4is arbitrary. For example, letters, symbols, or the like may be formed.
