发明名称 Sheet sensor for sheet printer with hollow cylindrical drum
摘要 The sheet sensor has a light barrier (9-11) with a light beam which is directed from inside the drum (3,4) towards a light opening in the drum in at least one angular position of the drum. The light beam is directed outwards from a point inside the drum transversely with respect to the axis of the drum. A light source or a light deflection system is arranged at this point and the deflection system receives light from outside the drum along a path parallel to the drum axis.
