を特徴とするサーマルプリンタのヘッド焼損防止機構。a rubber roller for transporting a print medium, a presser spring, a rotatable thermal head that is biased by the presser spring so that the print unit presses the rubber roller, and prints that are supplied to the comb roller and the thermal head. a paper guide for guiding a medium; a reflective photointerrupter for detecting the presence of a printing medium provided on the back side of the paper guide facing a hole provided in the paper guide; A direction in which the thermal head is retracted from the gorilla when the thermal head is urged in the same direction as the thermal head by a pressing spring and is positioned from the first position to a second position against the urging force of the pressing spring. In a thermal printer equipped with a lever that rotates the paper guide 1
A pair of swinging arms are provided on the four sides of the
First and second holding members are attached to sandwich the printing medium on the paper guide from the front and back, and the lever and the arm are connected, so that when the lever is in the first position, the printing medium is held in the When the lever is positioned close to the paper guide by the first holding member and the lever is in the second position, the reflective photointerrupter is moved from the paper guide by the second holding member to the print medium. A head burnout prevention mechanism for a thermal printer, characterized in that a connecting member is provided for interlocking the arm with the lever so that the arm can be retracted by a distance that does not detect the head burnout.
