Abstract

PURPOSE:To let desired light deflection to be effected highly accurately with a simple and small construction by balancing the rotating torque produced by a print disc and magnetic fields and the torque of a control spring produced thereby. CONSTITUTION:When a signal current is supplied between electrodes 22, 23 via amplifier 28, rotating torque is generated in the portion of the conductive pieces 9 provided radially to a print disc 4 and a scanning mirror 3 is rotated by way of a hollow shaft 1 to which the disc 4 is held by fixed. This rotation stops at the point when the rotating torque produced in the print disc 4 coincides with the torsional torque produced in a control spring 26 by the rotation of the hollow shaft 1. Hence, if AC or signal current of square wave or saw tooth wave is supplied between the electrodes 22, 23, the print disc 4 turns continuously in both directions within the range of the specified angle and the light beam scanning by the scanning mirror 3 is accomplished.
