发明名称 Folientastatur und Verfahren zu deren Herstellung
摘要 Disclosed is a film key sheet 20 with a key top 22 protruding from a resin film 9 which allows a further reduction in thickness and provides a sufficient degree of clarity in visually recognizing a display portion 23a thereof, and a method for manufacturing such a film key sheet 20. The film key sheet 20 has a film removal hole 9e piercing through the resin film 9, with a hole edge portion 9f raised from the surface of the resin film 9 being secured to the side surface 22a of the key top. Thus, no resin film exists on the upper and bottom surfaces 22d, 22e of the key top 22, so that it is possible to achieve a further reduction in thickness independently of the foldability of the resin film 9 and drawing accuracy and to provide clarity in visual recognition of a display portion 23a at the bottom 22e of the key top. <IMAGE>
