<P>PROBLEM TO BE SOLVED: To provide a lighting structure that imposes fewer touch sensor restrictions in an input key having a push button and a touch sensor. <P>SOLUTION: The input key includes a circuit board 2 mounted with a key switch 3, a flexible printed circuit board 7 with a touch sensor pattern disposed over the circuit board 2, a light guide sheet 11 disposed in close contact with the flexible printed circuit board 7, and a key top sheet 14 disposed in close contact with the light guide sheet 11, in this order from below (side apart from user). Lighting in which a light emitting diode 9 supplies light to the light guide sheet 11 can reduce restrictions imposed on the flexible printed circuit board 7. <P>COPYRIGHT: (C)2010,JPO&INPIT |
