Abstract

PURPOSE:To constitute a galvanomirror in which power supply to a movable part is not needed and to attain the speed-up of an optical memory device by using a permanent magnet in the movable part. CONSTITUTION:A neutral holding permanent magnet 201 and holding magnetic poles 202 and 203 are provided as the neutral holding means of the movable part. By moving the neutral holding permanent magnet and the holding magnetic poles left and right, adjustment can be easily executed as compared with the adjustment at the time of assembling and by controlling a current which is made to flow in a coil 204, the rotational angle of the movable part can be controlled. Thus, the galvanomirror which has a structure that the power supply to the movable part is not needed can be obtained and there is no fear that the disconnection, etc., of a feeder occurs at the time of acting at high speed. And it can be evaded that the coil is deformed by generating heat to be brought into contact with a magnetic circuit.
