Abstract: In an exemplary photographic exposure installation, supply magazines for image sheets of varying format are provided with a transport path for transporting the image sheets between rollers bearing in a resilient fashion against both sides of the image sheets. The rollers disposed on different sides of the transport plane are axially offset relative to one another by at least one roller-width, the track gauges of the rollers are adapted in pairs to the distance between the lateral borders of each format to be transported, and the rollers associated with the smaller formats are smaller in their diameter as well as being arranged more closely to the center of the transport path than the rollers associated with the larger format.

Abstract: An X-ray examination apparatus having a magazine for unpacked and unexposed X-ray film material, a transport device for transporting the film from the magazine to an exposure station and back to a collector magazine, the transport device having a housing which is sealed with the various magazines so as to be impermeable to light characterized by a system for regulating the humidity of the air in the housing of the transport device and including a blower having a discharge connection with the housing. Preferably, the system for controlling the humidity is adjusted so that the relative humidity of the air in the transport device is adjusted to a desired value for the particular characteristics of the film being utilized in the apparatus and the blower is adjustable so that it maintains an over-pressure within the housing to prevent leakage of atmospheric air into the housing.
