<P>PROBLEM TO BE SOLVED: To provide a light guide body for an indicator which can cause a wide range of a light emitting surface to emit light uniformly and enables an operator to recognize the light emission state when viewing the light emitting surface from a diagonal direction, a button switch, a recorder and a liquid jetting device. <P>SOLUTION: The light guide body is equipped with the light emitting surface 49 disposed adjacently to a light emitter 47 and a light guide section 51 for guiding the light emitted by the light emitter 47 to the light emitting surface. A light diffusion material 57 is diffused only in the prescribed thickness portion of the light guide section from the light emitting surface. The light guide section 51 is provided with a refractive optical means, such as a convex lens 65, which refracts the light emitted by the light emitter 47 so as to spread the light over the entire area of the light emitting surface 49. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
