ABSTRACT:
The disc reproducing apparatus of the invention comprises low- and high-speed belt drive mechanism for playback and forward/backward operations. The latter comprises speed change means which in response to the operation of a feed-forward or a feed-backward button reduces its speed to a medium speed level suitable for searching a desired portion of the record grooves. A carriage on which a pickup arm with a needle is mounted includes a means for selectively seizing the low- and high-speed belts so as to be driven at the low or high speed relative to the turntable. A loop-and-finger arrangement is included to serve as a means for moving the pickup needle between upper and lower positions at a variable speed in response to the selective operation of the belt catch means. A manual control lever is provided to release the belt catch means to allow the carriage to be manually moved to the original position while at the same time to raise the needle to the upper position when the power supply is cut off during playback operations.
