Disclosed is a photographic capturing device for the capturing of photographic image information from photographic media with a light source, with a stage for the photographic medium to preset a reference position for the projection of the photographic medium by way of a projection optics onto a detection element which detects the light originating from the light source and modulated by the photographic medium according to the image information, whereby a sample carrier with a sample is provided for the control of the focus of the projected image, and a positioning mechanism which removably places the sample carrier at the reference position for projecting the sample onto the detection element by way of the projection optics.

A storage for strip material is provided with an inlet for the strip material into the internal space of the housing and an outlet from the internal space of the housing. Inside the housing, holding means are provided which accumulate the strip material above the holding means where the weight of the strip material is less than a threshold value, and which release the strip material downward if the weight of the strip material exceeds the threshold value.

Storage for strip material

In a production line for photographic copies the individual sheets leaving the copy portion of the production line are distributed over a plurality of output conveyors and transported in accordance to a predetermined distribution pattern through a subsequent wet treatment and drying station. For facilitating subsequent collection of copies by order, a separation mark in the form of a deviation from the predetermined distribution pattern is inserted between separate orders on said output conveyors. The separation marks may be detected after the wet treatment station by a light barrier sensing device or the like, and used for controlling automatic sorting devices to collect copies by order.
