ABSTRACT:
In an impact type printing apparatus, leak of impact noise to outside can be reduced by (1) arranging the print head, platen and sheet exhaust port almost in a line and (2) setting the shape of guide ribs provided at the internal surface of cover having the aperture so that the envelope of guide ribs which has come closest to the platen at the center and periphery thereof of the sheet and is gradually separated from the platen at both ends of the sheet. Moreover, the optimum exhaust port can be selected depending on the type and thickness of sheet by rotation of cover or providing the slide mechanism.
