A camera for use with a film cartridge having a spool rotatable in a film winding direction to wind an exposed filmstrip into the cartridge and a light lock movable to be closed after the exposed filmstrip has been wound into the cartridge, comprising a film winder rotatable in engagement with the spool in the film winding direction to rotate the spool in the same direction, and a closing actuator rotatable in engagement with the light lock to close the light lock and including a film sensor for sensing the presence and absence of the exposed filmstrip to determine whether the exposed filmstrip has been wound into the cartridge, is characterized in that the film winder and the closing actuator are mutually coupled when the film sensor senses the presence of the exposed filmstrip, to prevent the film sensor substantially from applying any pressure against the exposed filmstrip, and when the film sensor senses the absence of the exposed filmstrip, to rotate the closing actuator to close the light lock when the film winder is rotated in the film winding direction.
