Abstract
A device for reading flat material having an endless perforated belt, guided over two rollers, one of which is driven. Material is brought from a feeder to an inlet arranged on both sides of the rollers and the belt transports the material to an outlet. The material is retained against the belt by vacuum. The device is adjustable relative to the feeder and, in one position, the entrance to the inlet is at the level of the feeder and, in the other position, the entrance to the inlet is at the level of the feeder. At least one reading device is provided, for reading the markings from the material being transported on the belt.On adjustment from the one position to the other, a reversal in the direction of rotation of the driven roller occurs and the reading device faces that side of the belt, the entrance to the inlet of which is at the level of the feeder.
