Abstract
A Patrone and a camera using the Patrone. The Patrone comprises a film wind spool arranged in a cylindrical body, of which upper and lower ends are light-tightly sealed. The body stores film so that the film can move freely in or out of the body in such a manner that the film can rotate freely, and is wound about said spool in roll form. Locking members are arranged in the cylindrical body and can be displaced freely relative to the spool. Ends of the locking members normally project outwardly from the cylindrical body. Locked members are arranged opposed to said locking members and are formed substantially as parts of one of the cylindrical body or spool. An elastic member normally urges each of the locked members toward engagement with an associated locking member. A camera includes an unlocking member which presses the locking members of the Patrone to displace them against the force of the elastic member when the Patrone is mounted in a camera thereby disengaging the locking members from the locked members and enabling the spool to rotate freely.
