特徴とするプリンタの紙送り装置。 A head gap adjustment lever for adjusting the gap between the platen and the printing head according to the thickness of the paper; and a lever for pressing at least one pressure roller against the platen with a preset pressing force, and for releasing this pressing force. The pressure roller moves toward the platen to increase the pressing force of the pressure roller when the gap is small, and increases the pressure of the pressure roller when the gap is large. a power transmission mechanism that moves the pressure roller away from the platen in order to maintain or reduce the pressure at a preset value; A paper feeding device for a printer, characterized in that the paper can be brought into smooth pressure contact with the paper and the paper can be transferred with appropriate frictional force.
