ABSTRACT:
A camera capable of communicating with an external device, such as an adjustment device for performing camera testing, checking and adjustment operations. The camera includes a cartridge compartment having a wall member to accommodate a film cartridge, the wall member including a recessed portion, e.g., a hole or concavity, in the inner wall surface of the cartridge compartment to accommodate communication contact points which electrically connect the external device to the camera. A control unit which controls camera operations receives signals from the external device via the communication contact points and performs a predetermined camera operation based upon the received signals. The cartridge compartment also includes film sensitivity contact points, the film sensitivity contact points including a standard potential film sensitivity contact point which is also used to connect the adjustment device. The adjustment device can also start the power supply of the camera in accordance with electrical signals from the adjustment device which control an electrical power feed device, such that an operator does not have to operate camera mechanisms while performing testing, checking and adjustment operations.
