ABSTRACT:
A blocking device in a foldable camera blocks the shutter release button to prevent an undesired exposure whenever the camera is folded and throughout each film transport cycle. The device is moved into blocking relationship with the release button in response to movement of a camera cover member to its closed position and in response to initiation of the transport cycle. The device is then moved out of said blocking relationship upon movement of the cover member from its closed position and upon completion of said cycle. The device includes a pivotable member bearing a blocking element and two sensing elements. One sensing element is actuable by closure of the cover member; the other sensing element is actuable by movement of a timing cam that rotates one revolution in synchronism with the transport cycle. The blocking element moves into the path of the release button whenever either sensing element is actuated. The device is especially useful in a foldable processing camera, wherein the film transport may be motorized.
