ABSTRACT:
A film cassette supporting spring for permitting the insertion of a film cassette having a first configuration into a film chamber where the spring supports the film cassette in position for the exposure of a film unit contained therein, and for preventing a film cassette of a second configuration from being so positioned. The supporting spring includes a film cassette engaging section located in the path of travel of a film cassette as it is being loaded into the film chamber. A resilient arm is coupled to the engaging section and is adapted to be engaged and deflected by a film cassette, having the first configuration, through a distance sufficient to move the engaging section out of the path of the incoming film cassette.
