Abstract
PURPOSE: To drive a feed motor intermittently in case of regenerative feed and drive it continuously at a constant speed in case of quick-feed or quick-return by using rotary pulses corresponding to the rotation of a turntable and pulses corresponding to the rotation of the feed motor to drive it.
CONSTITUTION: The pick-up is moved against the disk correspondingly to the rotation of feed motor in case of regenerative feed, quick-feed or quick-return. Rotary pulses SB are generated by turntable rotation checker 56 in responce to the rotation of turntable and moreover pulse signals SA are generated in responce to the rotation of feed motor 3 in every rotation angle. In case of the regenerative feed, intermittent drive signals are generated for driving the feed motor intermittently in response to rotary pulses SB and pulses SA. In case of the quick-feed and quick- return, constant drive signals are generated from the feed motor control signal circuit in responce to pulse signals SA.
