ABSTRACT:
In accordance with an illustrative embodiment of the present invention, a video tape cassette changer is disclosed that is intended for use with a video cassette tape player having a cassette receiving portion that includes a cassette raising and lowering mechanism for lowering a received cassette into a play position and raising a rejected cassette out of the play position. The changer includes a chute, which is positioned near the player receiving portion and may receive a stack of video tape cassettes for playing, and a support arrangement for supporting the stack of cassettes and for releasing the lowest cassette in the stack. A cassette insertion/extraction mechanism is positioned near the player receiving portion and the supporting arrangement for accepting a released cassette for insertion in the receiving portion and for accepting a raised cassette for extraction from the receiving portion and ejection from the changer. The support arrangement and the insertion/extraction mechanism are synchronized with the player receiving portion to control the changer so that a cassette for playing is inserted in the receiving portion after ejection of a rejected cassette from the changer.
