Abstract
PURPOSE: To make a movable part light and make a minuter rotation possible by arranging a coil part in the magnetic field formed between a yoke and a plate and regulating the rotation limit of the movable part by a pair of screws and a mirror substrate.
CONSTITUTION: When stopping part 11 is inserted into hole 31 of base stand 1, movable part 4 is stopped by compressing the tip of screw 13 in hole 9 of base stand 1 to stopping part 11 at the position where screws 14 and 17 are brought into contact with V-shaped long groove 27 and conical concave part 26 respectively. Screw 14 is connected to base stand 1 by a screw, and the position can be adjusted by rotating the screw. Then, coil part 7 is arranged in the magnetic field between yoke and plate 29 which is formed by the magnetic path passing through permanent magnet part 2, yoke 3 and plate 29, and movable part 4 is rotated in the arrow direction by the electromagnetic force of coil part 7. As a result, the movable part can be made light and can follow a minute change.
