ABSTRACT:
A film rewind button and a door release button are located on the body of a camera. The rewind button is manually movable from an original position to a rewind position to initiate automatic rewinding of an exposed filmstrip back into a light-tight cartridge in the camera. The release button is manually movable from a latch position for securing a rear door of the camera closed to a release position for releasing the door to permit it to be opened in order to remove the cartridge from the camera. As a safeguard against the door being mistakenly opened before rewinding of an exposed filmstrip is initiated, there is provided protective means for preventing the release button from being manually moved from its latch position to its release position unless the rewind button is first manually moved from its release position to its rewind position.
