ABSTRACT:
A film cassette sensing and retaining unit for film handling apparatus. The unit is responsive to completed insertion of a cassette into the film handling apparatus to mechanically latch the cassette in position and to electrically condition and actuate the film handling apparatus. Upon termination of operation of the film handling apparatus, the unit is effective to unlatch and eject the cassette and thereby deactuate the film handling apparatus. A disabling mechanism is provided to prevent premature unlatching and ejection of the cassette in a particular circumstance.
