Abstract
Apparatus for interfacing a battery powered photographic camera with a battery containing film cassette is disclosed. When the cassette is interfaced with the camera, electrical contacts in the camera engage the terminals of the cassette battery through access ports in the cassette housing. These access ports are provided with removable battery terminal masks to prevent accidental completion of an electrical circuit. The camera is equipped with enclosure means for receiving the cassette and with means associated therewith for removing the battery terminal masks so as to expose the terminals which can then engage the camera contacts for completion of an electrical circuit.
