Abstract
A storage device for receiving and giving off a photographic band material. The storage device can be used for the buffering of photographic material and/or as indication or control element, and includes an inlet and an outlet for the photographic material band. A weight member pushes onto the photographic band material between the inlet and the outlet for the tensioning thereof, the height of which is changed during changing of the stored band length by interaction between the band tension and its inherent weight. A change in height of the weight member is coupled with a rotation of a driven member of a direction dependent coupling, the drive member of which is rotated in a free wheeling direction. A detector detects a locking condition of the direction dependent coupling, which occurs during free fall of the weight member, and a controller controls the transport of the band based on the detection.
