Abstract
It is made possible to locate arbitrarily a light guiding device and a light emitting means. A notch (11) having a triangular cross-section is formed on a bottom (inner) side of a light guiding device (10) formed so as to have a rectangular cross-section. Furthermore, a light emitting source (12) is provided under the notch (11) of this light guiding device (10). The light emitting source (12) is mounted on a circuit board (13), and controlled according to the state of control or setting in, for example, the electronic appliance. When the light ray from the light emitting source (12) is irradiated toward the notch (11), the emitted light ray is reflected by a reflective face (14) formed by the notch (11) so as to be a plane and a front face (15) of the light guiding device (10) becomes luminous. In addition, the irradiated light ray is partially transmitted through the reflective face (14), and a top face (16) of the light guiding device (10) also becomes luminous. As a result, the two outer faces (15) and (16) become luminous.
