ABSTRACT:
A disc loading structure capable of automatically and positively loading a disc in a disc apparatus with a simple structure irrespective of the size of the disc and carrying out a substantial decrease in power consumption in use and manufacturing costs. A mechanical sensor link is pivotally arranged so as to be pivotally moved due to engagement with a disc and a lock member is pivotally arranged and selectively engaged with the sensor link so as to be pivotally movable in association with the pivotal movement thereof. The lock member selectively serves to lock a stopper arm at a small-diameter disc position depending upon the position of the sensor link pivotally moved. Also, the structure includes a large-diameter disc regulator for holding the stopper arm at a large-diameter disc position.
