<p><P>PROBLEM TO BE SOLVED: To provide a keyboard with which the cracking arising in a key can be prevented by attaching weights hereto. <P>SOLUTION: Attaching holes 11a and 11b are formed to a key body 11 of the key 10 constituting the keyboard from its one side toward the other side and the weights 12 for adjusting weights are attached into the attaching holes 11a and 11b. The weights 12 are constituted of a high specific gravity resin composed of a mixture of powdery tungsten and a resin material and is made elastically deformable. The weights 12 are shrunk in a prescribed direction and are inserted into the attaching holes 11a and 11b in the state of making the direction where the weights 12 are restored and elongated by elasticity complying with a longitudinal direction. The weights 12 are fixed to the attaching holes 11a and 11b by bringing projecting parts 12a and 12b tending to be restored and elongated by the weights 12 into pressurized contact with the peripheral surfaces of the attaching holes 11a and 11b. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
