ABSTRACT:
The present invention relates to a pickup carriage feeding apparatus of a disc player, comprising a driving motor, a pair of opposite racks connected to each other which are formed in parallel on the lower surface of the pickup carriage, a pair of driving gears mounted between the racks and respectively meshed with each of the racks, and a belt pulley in a coaxial connection with one of the gears for transmitting a driving force of the driving motor. Accordingly, the reliability of the disc player is enhanced since the feeding operation of the pickup carriage can be smoothly and stably attained with no moment or backlash.
