Claims

[Claims for Utility Model Registration] A platen and a carrier shaft arranged parallel to a frame, a carrier movably supported by the carrier shaft, and a printing head mounted on the carrier so as to face the platen. , an eccentric member rotatably fitted into the frame and fitted eccentrically to the carrier shaft, and the position relative to the platen is changed by rotating the eccentric member to eccentrically move the carrier shaft. The printer is configured to adjust the gap between the platen and the printing head by adjusting the gap between the platen and the print head, further comprising a biasing means for biasing the carrier shaft in a predetermined direction different from the axial direction of the carrier shaft. printer.
