ABSTRACT:
An arrangement for determining two or more superimposed film sheets, particularly X-ray film sheets, in a transport after their withdrawal from the film sheet stack, has a light barrier with a light source at one side of the transport path and a photoreceiver at the other side thereof, and an evaluating circuit connected with the photoreceiver for producing a signal corresponding to the presence of two or more sheets and including a computer supplied with a value of the density of a first or test sheet introduced into the light barrier between the light source and the photoreceiver, so that the supplied value serves as a reference signal for measuring the next film sheet.
