  • Patent number: 8111274
    Abstract: A thermal printer has a thermal head pivotally mounted on a main body frame to pivot toward and away from a platen roller. The platen roller has shaft bearings at opposite ends thereof that are removably inserted in two spaced-apart opposed slots formed in the main body frame to rotatably support the platen roller. First springs bias a pivotal lock arm to a locked position to prevent removal of the shaft bearings from the slots, and second springs bias the thermal head toward the platen roller. Manual pivotal movement of the lock arm to an unlocked position permits removal of the shaft bearings from the shaft. The biasing directions of the first and second springs are parallel, which reduces the stroke distance of the first springs resulting in size reduction of the thermal printer.
