PROBLEM TO BE SOLVED: To provide a film-integrated keytop, which can prevent distortion from occurring at the time of visual identification, and the external appearance quality of which can be improved, and furthermore productivity of which can be improved because of the easiness of forming a decoration layer or the like on the back of a translucent resin keytop. SOLUTION: In a film-integrated keytop 11, a translucent resin film 14 is coated and formed on the front surface side of a translucent resin keytop 12 constructing a push button switch. On the rear of the periphery surface of the translucent resin keytop 12, a projecting part 15 projecting outward all over the periphery is formed. On the back surface 15a of the projection part 15, a gate trace part 17 is formed by a resin injection gate for the translucent resin keytop 12 being molded by an injection molding method, and a vent trace part 18 is formed by air vent. Furthermore, the back surface of the translucent resin keytop 12 is flat and projects backward from the back surface 14a of the translucent resin film 14. COPYRIGHT: (C)2004,JPO |
