Abstract
A storage for photographic material with a base (20, 120, 220) rotatable around an axis (30), with an input arrangement (16, 116) positioned at an outer circumference of the base, with a removal arrangement (18, 118) positioned at the axis (30, 130) of the base (20, 120, 220), whereby two photographic material belts are wound/unwound, and, in particular, one close to the axis (30, 130) and one close to the outer circumference of the base (20, 120), whereby a loop (42) between the belts leads to a photographic material exchange from the outer belt to the inner belt, whereby the winding direction is preferably reversed, whereby, the base (20, 120) is divided into two sections (12, 14; 112, 114; 212, 214), whereby the one section (14; 114; 214) surrounds the other section (12; 112; 212).
