<P>PROBLEM TO BE SOLVED: To make wiring to an electric component easy with less interference with other components without impairing an outward appearance. <P>SOLUTION: A through hole 1b is formed, penetrating a key 1 from the top surface 1c to the reverse surface 1d, at a part which is not viewed in playing operation behind a panel surface 5, and a bundle fastening part 12 is fixed to a rear upper part 1ca. A bundle 9 has its one end 9a connected to a connector 25 of a light emission unit 20 bonded and fixed to an upper part 1aa of a droop part 1a of the key 1 and the other end 9b connected to a connector 14 on an electronic circuit board 15 provided behind the key 1. The bundle 9 passes under the key 1 to penetrate the through hole 1b and is led out to above the key 1 and then led to the connector 14 by being fixed halfway to the bundle fastening part 12, so that the light emission unit 20 and electronic circuit board 15 are electrically connected. <P>COPYRIGHT: (C)2004,JPO |
