In a printer that prints by moving the print head in space opposite the platen, the ink ribbon is interposed between the paper set between the platen and the print head to prevent ribbon contamination. The ribbon protector has a structure in which two plate-like members of the same shape are stacked together, each having a window portion through which the pin of the print head can pop out, and at least one of the two plate-like members A ribbon protector, characterized in that conductive members are disposed facing each other on the inner walls of the press-contact range of the tip, and a spacer made of an elastic member is interposed between the two plate-like members. 2. The ribbon protector according to claim 1, which is a registered utility model, characterized in that, as spacers, rubber protrusions of a constant height are dotted on the inner wall of one or both of the two plate-like members.
