Transfer mechanism for information carriers

Abstract

A disc support and transfer mechanism for a disc changer including a magazine for supporting a plurality of discs in generally parallel vertical storage planes, and a disc transfer mechanism for transferring a selected disc from the magazine along a vertical transfer plane aligned with its vertical storage plane, the disc transfer mechanism including a longitudinally movable transfer bar extending over the magazine, the magazine and the frame being mounted for relative movement to position the transfer bar in an initial position above the selected disc resting in the magazine. First and second arms extend vertically down from the bar, the first arm being fixed to the transfer bar and the second arm being pivotably mounted to the transfer bar. The arms are located so that neither arm initially engages the disc. Upon movement of the transfer bar the first and second arms engage and roll the selected disc back and forth along a transfer plane to and from its storage plane; a first cam and a second cam pivot the second arm into and out of engagement with the selected disc responsive to movement of the transfer bar.
