A tape cassette loading mechanism for receiving a hinged cassette containing a tape supply reel and for automatically opening the cassette and advancing the supply reel into an operative position. The mechanism is used with tape transport apparatus of the type having supply and take-up reels driven by surface engagement with a capstan. A pair of pivot arms engage opposite halves of the cassette and pivot apart to open the cassette. A motor-driven lead nut mechanism rotatively drives a control arm to move the pivot arms and thereby open the cassette, and to simultaneously advance the supply reel along an arcuate path into the operative position in engagement with the capstan. The pivot arms simultaneously move the cassette in a lateral direction to match the lateral component of the advancing movement of the supply reel, thereby preventing the opened cassette from physically interfering with the advancing reel. |
