PROBLEM TO BE SOLVED: To reduce the number of components by integrating a key with a light guide body and to improve the degree of freedom of a light emitting range of a multidirectional operation key and its circumference. SOLUTION: This key light guide mechanism comprises: two or more contact mechanisms 3 installed on a board 2; the key 1 formed of a transparent or translucent material for multidirectionally selecting, pressing and operating the plurality of contact mechanisms 3; an operation panel 4 with an opening formed corresponding to the key 1; and an illuminant 5 mounted on the board 2 for illuminating the key 1. For the key 1, the light guide body for guiding light emitted from the illuminant 5 to the key 1 is formed in an integrated structure. The operation panel 4 may be formed of a transparent or translucent member, and a part or all of the surface of the key 1 may be formed of a shading member. Thereby the number of components is reduced and the degree of freedom of an illumination range of the key 1 and its circumference is improved. COPYRIGHT: (C)2005,JPO&NCIPI
