Abstract
A dot-matrix impact printer includes a print head in a housing for printing a recording sheet fed around a platen. The recording sheet is pressed against the platen by a sheet presser roller. A roller cover or a flap is disclosed as a sound insulating wall closely to the sheet presser roller and has an edge held against the housing. The space above the print head is closed by the housing, the platen, the sheet presser roller, and the platen, so that the impact noise produced when the printer is in operation will not leak out of the housing, while at the same time the recording sheet fed around the platen is not blocked by the closure mechanism.
