Abstract
A plurality of magazines each of which contains a plurality of film sheets of a type different from those contained in the other magazines are accommodated in movable trays. These movable trays are disposed within an elevator in such a manner as to be movable with respect to the elevator from a retracted position to a film unloading position. Each of the movable trays has a hook. When the elevator is moved to a desired position, an insert member such as a rod enters the hook located at that position so as to move the tray to the film unloading position at which the film sheet is taken out of the magazine.
