The illumination device includes: a light guide having an end face for taking in light, a diffuse reflecting surface for diffusely reflecting the light taken in from the end face, and a light exit surface for emitting the light that is diffusely reflected at the diffuse reflecting surface towards an irradiation surface. The illumination device further include a reflector having a diffuse reflecting surface that reflects light from the light source toward the one end face of the light guide. The light guide has, at the one end, a flange portion that abuts the reflector, the light source is mounted to a circuit board, and the reflector is held between the flange portion of the light guide and circuit board so as to maintain a predetermined gap between the light source and light guide.

Abstract: PURPOSE:To increase the number of steps of operation without increasing the number of permanent magnets by arranging the permanent magnets so that when two adjacent permanent magnets are positioned opposite a 1st electromagnetic coil group, a 3rd permanent magnet adjacent to the permanent magnets is positioned between 2nd electromagnetic coil groups adjacent to the 1st electromagnetic coil group. CONSTITUTION:The permanent magnets 22 are so arrayed that adjacent permanent magnets are opposite in polarity. When rotating right-angled components 101a and 101b of an electromagnetic coil 32A face a permanent magnet 22, another permanent magnet 22 is positioned right in the middle between rotating right-angled components 101a and 101b of an electromagnetic coil group 32B. Here, when the permanent magnets 22 rotate by a half as large as the 30 deg. array angle of the permanent magnets 22, i.e. 15 deg., the electromagnetic coil groups A and B are only replaced and exactly the same stable relation is obtained again. The number of steps which is double as large as before can be obtained with an input signal consisting of a half number of pulses by this constitution.
