Abstract
A thermal printer having a reciprocable carriage on which a thermal head is carried. The printer further includes a toothed rack and a driving plate both of which are rotatably held to a shaft. The rack acts to rotate the thermal head toward and away from a recording sheet. The driving plate has a protrusion for rotating the rack in one direction. A pin protruding from the driving plate on opposite side to the rack is fitted in a grooved cam, which serves to rotate the driving plate. A tension spring is mounted between the rack and the driving plate to cause the protrusion of the driving plate to angularly bias the rack in one direction so that the force of the tension spring urges the head toward the recording sheet.
