ABSTRACT:
A carriage has a support shaft for supporting a plurality of film rolls and can be closed by a light shield cover to place the film rolls in a light-shielded state. A film roll storage mechanism is disposed in a dark room and has a shank for receiving the film rolls from the carriage. The film roll storage mechanism can transfer the film rolls one at a time from the shank onto a film unwinding shaft. A positioning mechanism positions the support shaft and the shank coaxially with each other and locks the carriage with respect to the film roll storage mechanism.
