Abstract
A camera of this invention is provided with: a housing cover for covering an opening of a patrone housing chamber, a lever movable between a position to lock the housing cover and a position to unlock the housing cover, a movable roller for deciding whether a film is drawn out of a patrone loaded in the patrone housing chamber, a lock lever for allowing the lever to move to the position to unlock the housing cover when it is decided that the film is not drawn out and preventing the lever from moving to the position to unlock said housing cover when it is decided that the film is drawn out, a mount plate for moving to a position to drive a spool shaft of the patrone in correlation to the loading of the patrone and for holding a position between the spool shaft drive position and the opening of the patrone housing chamber when the patrone is not loaded, and an eject lever having a notch for engaging the mount plate in the spool shaft drive position and a bent portion for disengaging the mount plate from the notch in correlation to the movement of the lever to the unlock position. Such structure of the camera prohibits the housing cover from being unlocked when the film is drawn out of the loaded patrone.
