Abstract

PURPOSE:To prevent stain of printing paper caused by side printing by constituting the width of a hammer to be narrower than a pitch of a projected screw formed on the outer-peripheral surface of a cylindrical platen. CONSTITUTION:The projected screw 6a is formed on the outer periphery of the platen 6 and a separating member 6b for preventing a recording medium 33 from contacting with the projected screw is fixed between the respective pitches of the projected screw 6a. The separating member 6b is formed of an elastic material such as rubber and sponge, spring metal or plastic or the like and the outside diameter of the member is slightly larger than that of the projected screw 6a. Since the recording medium 33 is pressed against the projected screw 6a while the separating member 6b is pushed aside by a hammer head 27 having a width narrower than the interval of the projected screw 6a in the axial direction, the separating member can not be pushed aside other than the part thereof pushed directly by the hammer head and thereby unexpected sticking of ink to the recording medium is prevented.
