摘要： A manufacturing method for key tops includes the steps of molding a light-shielding film on a to-be-peeled shield by a plane printing, effecting colored printing to provide a readout part at a predetermined position on it in the state of a plane sheet prior to the 3-D molding, then sucking a printed light-shield film sheet on a metal mold with an evacuation system, adsorbing said light-shield film sheet onto the wall face in the metal mold. A push mold may be used with a suction system so as to be positioned in the female mold. Materials such as silicone are put into this metal mold for one-piece molding. A laser processing is effected on the surface of a key top prepared in a 3-D shape to form a desired pattern. By making the light-shield printing and pattern printing in the state of a plane sheet prior to the 3-D molding and effecting only a pattern processing by laser cut in the state of a stereographic shape, a laborious coating has been omitted which also results in improved accuracy of printing and at the same time a reduced number of steps.

摘要： A key pad has resin key tops on a key sheet. The resin key tops have in their side surfaces clearance portions of a configuration in conformity with an outer configuration of interference members at least an upper portions of which are situated in displacement regions at bottom surface edges of the resin key tops allowing their displacement when they are depressed.
