ELECTRONIC CONTROL SYSTEM FOR MULTIPLE CASSETTE RECORD AND/OR PLAYBACK APPARATUS ABSTRACT OF THE DISCLOSURE An electronic control system for controlling the sequential operations in a multiple cassette record and/or playback apparatus of the type having a supply of tape cassettes, a motor-driven conveyor for conveying individual cassettes from the supply to a record/playback station and thence to an output store, the record/playback station having a motor- driven deck for loading and unloading a cassette, and the output store having a motor-driven elevator for loading a recorded cassette into the output store. Monitors are provided for monitoring the operation of each of the motor- driven conveyor, deck and elevator to sense when a cassette has been conveyed to the record/playback station, when a cassette has been loaded onto the deck and when a cassette has been loaded into the output store. Logic circuitry is responsive to the monitors for energizing motor-drive circuitry in accordance with a predetermined sequential cycle of operation. Malfunction detection apparatus is provided to detect if a sequential cycle is not completed within a pre- determined time and to prevent the initiation of a subsequent sequential cycle in the event of a malfunction. -1-
