ABSTRACT:
A sheet film magazine for a film changer has a conveyor for conveying individual film sheets from a film stack to an exposure or receptacle portion of the film changer. The conveyor comprises at least one conveyor wheel which is attached to a shaft that is parallel to the plane of the film sheets and which is driven with a drive mechanism in the conveying direction of the film sheets. The conveyor also has a spacing mechanism for spacing between a film sheet and the conveyor wheel such that the conveyor wheel, when conveying a film sheet from the sheet film magazine to the exposure or receptacle portion, presses against the surface of the film sheet, and is removed from this surface after the end of the film conveying. In order to enable a high film conveying frequency with a conveyor of this type in a simple way, following the end of a film conveying, the conveyor wheel is separated from the surface of the film sheet with the assistance of a separating mechanism.
