Claims

[Claims for Utility Model Registration] (1) A printer main body 3 having a platen 7, a head mounting plate 1 having a thermal head 4, and applying pressure to the head mounting plate 1 so as to press the thermal head 4 against the platen 7. The printer is provided with at least an elastic member mounting plate 2 having an elastic member 5, and the head is mounted so that the head mounting plate 1 is located on the side of the printer main body 3 and the elastic member mounting plate 2 is located on the head mounting plate 1. This is a thermal printer in which a mounting plate 1 and an elastic member mounting plate 2 are rotatably mounted on a shaft 8 of a printer main body 3 at rear bearing portions 9 and 10, wherein the rear bearing portion 9 of the head mounting plate 1 is rotatably mounted on a shaft 8 of a printer body 3. 8 has an elongated hole that engages, the elongated hole is formed with its longitudinal axis directed in the vertical direction, and the elongated hole is formed so that the desired contact between the resistive portion of the head 4 and the platen 7 is achieved. A thermal printer characterized in that the horizontal position of the head mounting plate 1 is defined, and the rear part of the head mounting plate 1 is movable up and down. (2) The elongated hole is formed in a shape where the printer main body 3 side is opened, and the elastic member mounting plate 2 can be removed from the shaft 8 by opening it. 1
Thermal printer described in section. (3) The thermal printer according to claim 1, wherein the head mounting plate 1 and the elastic member mounting plate 2 are held at their distal ends by removable fasteners.
