Abstract

PURPOSE:To eliminate the need of an electromagnetic clutch for switching a motor and to reduce the cost of a device by applying each turning force of a continuously rotating motor and a stepping motor directly to a rectilinealy sliding driving portion. CONSTITUTION:At time of a low-speed feed such as normal reproduction, a pulse current of a fixed period is supplied to a stepping motor 24, so that a feed screw 15 is rotated by the motor 24 through gears 15, 16 to feed a pick-up 1 at a low speed. At this time a d.c. motor 21 is not load because of a low-speed feed. At time of a high-speed feed such as rejection, a driving current is supplied to the d.c. motor 21, whereby the feed screw 15 is fed at a high speed. At this time, the stepping morot 24 is load, which causes no problem because static cogging of the stepping motor 24 is eliminated.
