Abstract
PURPOSE: To enable the moving part to follow fine change and to reduce the effect by external magnetic field, by constituting the unit so that the distance between the mirror and the rotary fulcrum can be reduced without using permanent magnet for the moving part.
CONSTITUTION: The unit consists of the base plate 1, permanent magnet 2, york 3, plate 29 and moving part 4, and the permanent magnet 2 is magnetized with the direction in contact with the york 3. The moving part 4 consists of the mirror substrate 22, mirror 6 fixed on it, core 12 fixed on opposite surface with the mirror fixed surface, latch 11 fixed to one end of the core 12, and coil 7 wound around the mirror plate. The coil 7 is located in the magnetic field formed between the york 3 and the plate 29 and the latch 11 is latched to the base plate 1. When current flows to the coil 7, the moving part revolves to the arrow, but when no current is present, the moving part 4 restores to the original position by the elasticity of the core 12.
