The switch mechanism 20 has a membrane switch sheet 22 mounted on the supporting plate, holding a contact part at a position corresponding to the key top. Each link member has a sliding part 46 sliding movement freely engaging with the supporting plate, and the membrane switch sheet has through-holes 56 at an area where the sliding part of each link member engages with the supporting plate. The sliding parts of the link member are put on the supporting plate through the through-holes on the membrane switch sheet. <P>COPYRIGHT: (C)2006,JPO&NCIPI
62	Key switch	JP2002230440	2002-08-07	JP2004071406A	2004-03-04	ITO HIDEKI
PROBLEM TO BE SOLVED: To provide a key switch allowing a key top to be vertically moved in a horizontal form even if two levers combined in a pantograph-like form are not used. SOLUTION: This key switch 1 is equipped with: an elastic member 6 for elastically biasing the key top 5 upward; a board 2 capable of holding the elastic member 6; and a switch circuit having fixed contacts 2c, 2c switchable along with the vertical movement of the key top 5, and a moving contact 6b. First and second link members 3 and 4 are disposed adjacently to each other at a predetermined angle so that two pairs of plate materials 3c and 3d, and 4c and 4d are formed into a foldable hinge-like form by using intersecting points 3b and 4b as fulcrums, respectively. The folding angle α of the two pairs of the plate materials 3c and 3d, and 4c and 4d are varied by gearing with the telescopic motion of the elastic member 6 caused by the vertical movement of the key top 5.

80	Method For Manufacturing Thin Keypad Assembly And Such Assembly	US11673640	2007-02-12	US20080191904A1	2008-08-14	Kai-Jie Tsao
A method for manufacturing a thin keypad with no seams on a panel surface and such assembly includes the following steps. Inks of different colors are printed onto the surface of a rigid substrate so as to shape panel forms and light-transmitting numerals, letters, symbols, a navigation-key pattern, a dialing pattern and an ending pattern. The panel surface is formed with a plurality of grooves after machining and cutting. Then, inks of different colors are printed onto the surface of a soft substrate so as to form a lining sheet of a light-shielding layer and a reflective layer corresponding to patterns of the panel. The thus-formed panel and lining sheet are disposed into a mold. Rubber is filled in the mold and, after pressing, bound with the bottom of the lining sheet to form a light-guiding layer. At the same time, the light-shielding layer, the reflective layer and the rubber are extruded on the panel surface, so that no seams exist between the keys of the panel surface. Finally, laser is radiated to dot on the light-guiding layer to form thereon light-guiding micro structures having a light-condensing effect.
