An engageable locking lever prevents the gear from being rotated until disengaged by movement of the cover in one of the opposite directions in which a movable gear rack having a set of engagement teeth engages the unlocked film winding gear and rotates the film winding gear when the cover is moved in one of the opposite directions to wind film into a film cartridge.
