摘要

Product chute comprises a transparent plate (2) with a sliding surface and a rear side, and at least one light barrier arrangement with an emitter (30) and a receiver (31). A mechanically stable, extensively non-transparent support plate (4) attached to the rear side of the plate contains at least one light-permeable region in the region of the optical axis (32) of the light barrier arrangement. Preferred Features: The light-permeable region is a bore, preferably a fiber optical light guide. The transparent plate and the support plate are removably fixed together, e.g. with adhesive or double-sided adhesive tape.
