Ribbon protector including electro-conductive elements and platen gap adjustment device incorporating the same
 A ribbon protector is used for protecting paper from contamination by an ink ribbon in a printer, where the protector is inserted between paper located between a platen and a printing head. The printing head facing the platen performs spacing movement for printing. Two connected plate-like elements are provided with through openings for passage of the pin of the printing head. Mutually engageable electroconductive elements are provided on the inner walls of the two plate-like elements, at least in the area where they are compressed by the tip of the printing head, and spacers which are made from resilient materials are located between the two plate-like elements.
