The deflecting unit projects over the device casing (32) and has an additional window (53). A detection unit for light reflected from a reference mark is connected to an evaluation and control unit, which control a tilt device (37), to tilt the rotation axis of the deflection device. Automatically-controlled positioning units (40) are provided, to adjust the axial position of deflecting unit according to the position of the reflection from the reference mark.",
