A camera comprising a housing, a lens, a cassette mounted in the housing adjacent the lens, a rotary shutter mounted for rotation between the lens and cassette and an aperture plate mounted between the rotary shutter and cassette. A motor is connected by a pulley belt to the periphery of the rotary shutter to rotate the shutter. The shutter carries a cam which cooperates with a film advance mechanism mounted on the plate. The film advance mechanism includes a pin slidably mounted in a block, the pin riding in and out of slots in the film as the block is reciprocated by the cam to advance the film. A similar pin is slidably mounted on a block adjustably mounted on the plate to move in and out of the slots in the film, the pin being connected to a movable contact in a control circuit for the film. The rotary shutter also carries a friction wheel which engages a drive disc, the drive disc being connectable to the take-up reel in the cassette to take up the film as it is advanced through the camera.
