Abstract
A device for detecting edges of sheet-shaped print materials (), especially of transparencies, that are moved along a transport path through a sheet-processing machine has a beam transmitter () and a beam receiver (), whereby beam transmitter () and beam receiver () are mounted on different sides of the transport path in such a way that the beam path forms an acute angle to the surface of the sheet-shaped print material (). Electronics () evaluate the beam received at the beam receiver (), whereby the beam receiver () is at a lesser distance to the transport path in comparison to the beam transmitter ().
