ABSTRACT:
Disclosed is a preferably transparent removably mounted cover plate for covering the top opening or printing point area in a printer, e.g. a needle printer, which serves to reduce noise and to prevent the introduction of foreign substances and dust. Of particular advantage is the inclusion on the cover plate of paper guide elements, a switch actuating cam which acts on a switch to shut off the machine when the cover plate is removed or swung out, and a paper tear-off edge.
