Abstract
A key top assembly integrated with a film, wherein: a plurality of key tops can be placed inside one frame; and a resin film 13 which connects the body of a circumferential outer key top 1 to the body of a core key top 2 placed inside the body of the above-mentioned outer key top is formed into a bent shape at a position lower than the lower ends of the areas where the resin film is bonded to the bodies of the key tops, or the interior portion of the base of the body of the outer key top is cut out with the result that that the interior portion of the base is formed at a position higher than that of the exterior portion of the base; and whereby: the clearance between the key tops is rendered small; no key top interlocks with any adjacent key top; and a good appearance is presented.
Claims11
A key top assembly integrated with a film, wherein:
- a key top body made from a resin is integrated with a resin film, the resin film is formed by being bent to the same shape as that of an upper surface of the key top body, the resin film linking bottom ends of side surfaces of at least two adjacent key top bodies, a core key top of said two key top bodies is placed inside a circumferential outer key top of said two key top bodies, and the resin film which connects the body of said circumferential outer key top to the body of said core key top is formed into a bent shape at a position lower than lower ends of areas where said resin film is bonded to the bodies of said two key tops.
A key top assembly integrated with a film, wherein a key top body made from a resin is integrated with a resin film, the key top body has a push stud by which the resin film is pierced, the resin film linking bottom ends of side surfaces of at least two adjacent key top bodies, a core key top is placed inside a circumferential outer key top, and the resin film which connects the body of said circumferential outer key top to the body of said core key top is formed into a bent shape at a position lower than lower ends of areas where said resin film is bonded to the bodies of the said two key tops.
A key assemble comprising:
- a switch substrate;
- first and second key bodies separated by a gap and movable toward and away from said switch substrate, each key body having a display surface and a substrate surface, said display surface being substantially diametrically opposite said substrate surface of a respective said key body;
- a resin film connecting said first and second key bodies, said resin film having a U-shaped section in a gap area between said first and second key bodies, said U-shaped section being arranged between said switch substrate and said substrate surface of said key bodies, said U-shaped section also being spaced from said substrate surfaces and said switch substrate.
