摘要：
A ribbon mask for use with a impact dot matrix printer is provided. The ribbon mask comprises a head confronting surface and a pair of opposed side plates each positioned on an opposite side of the head confronting surface. An obtuse angle is formed between said head confronting surface each of the opposed side plates. A pair of fitting tabs are also provided. Each fitting tab is positioned on one of the pair of opposed side plates. An acute angle is formed between each of the fitting tabs and a plane parallel to a plane in which the head confronting surface lies. As a result of this construction, when the ribbon mask comes in contact with a sheet of a recording medium, the ribbon mask is deformed so that a portion of the head confronting surface comes into contact with an end of a recording head, which in turn prevents the ribbon mask from interfering with the sheet of the recording medium.
