Abstract

PURPOSE: To simplify the constitution without using a multistage variable speed mechanism and expensive pulse motor, by intermittently or continuously supplying a motor with driving power for the motor, driving the conveyance mechanism of a reproducing element, corresponding to a conveyance speed.
CONSTITUTION: The movement drive system for a reproducing element is so constituted that DC motor M is supplied with a high voltage to flow much electric armature current and large torque is generated in consequence to provide stable rotation. Then, the ratio of a DC-power supply period to a cut-off period is varied by varying the pulse width of output pulses from monostable multivibrator MM. Consequently, the conveyance time of a video disk can be fixed to a desired value within the range of 30W360sec and the speed ratio of the minimum to the maximum is set 7,000W8,000 without using a mechanical variable speed mechanism and expensive pulse motor, thereby realizing needed fast-traversing operation as well.
