ABSTRACT:
A cartridge changing apparatus according to the present invention includes a plurality of holders, each holding a cartridge with a disc inserted therein, a pair of base carriers each having a gripping portion for gripping a pin fixed to one of the plurality of holders and each engaged with one of a pair of screw shafts so as to be able to move back and forth as the screw shafts are rotated, and a pair of slide carriers which are combined with the base carriers and can be moved on the screw shafts together with the base carriers, respectively. Cartridges are replaced by the back and forth movement of the pair of the carriers. Consequently, it is possible to simplify the carrier construction, eliminate the necessity of providing a plurality of gripping functions for one set of the carriers, thereby leading to reduction of required parts and further, make the carriers move vertically without interfering with anything at a position in which unloading is completed, thereby leading to reduction of operating time.
