送り機構。[Claims for Utility Model Registration] In a thermal recording device configured such that thermal paper is placed on a platen that rotates around a platen shaft, and a thermal head is used to record on the thermal paper, a thermal head is provided at both ends of the platen shaft. It has a structure in which it is slidably assembled with the platen shaft through a "loose fit" and the outer peripheral portion contacts the lower part of the thermal head to raise or lower the thermal head according to the rotational direction of the platen shaft. a pair of cams,
The platen shaft is fitted between the pair of cams, and the platen is slidably assembled to each other in a "loose fit"; a one-way clutch configured to connect the platen shaft and the platen when the platen shaft rotates, and connect the platen shaft and the cam when the platen shaft rotates in the reverse direction; The platen is rotated in accordance with the rotation of the platen shaft, and the cam is rotated by friction to lower the thermal head, and when the platen shaft is reversed, the platen is stopped from rotating, and the rotation of the cam causes the thermal head to move down. A paper feeding mechanism for a thermal recording device characterized by raising the thermal head.
