Abstract

In a printer having a platen, a print head disposed opposite to the platen, and a ribbon mask fixedly provided on the print head and having a masking plate provided with an aperture to expose only the front end of the print head to the platen, an ink ribbon is extended through a space between the platen and the print head, and the masking plate is disposed between the platen and the ink ribbon to shield a recording sheet wound round the platen from the ink ribbon. The aperture of the masking plate has inclined edges inclined to a direction perpendicular to the direction of movement of the print head so as to intersect a platen center obliquely. In case the side edge of a floating portion of the recording sheet is caught in the aperture of the masking plate while the print head is moved, the side edge slides along the inclined edge to escape from the aperture, so that the side edge is not caught in the aperture of the masking plate.
