The figures show an embodiment of the present invention, in which Fig. 1 is a time chart showing the time relationship of solenoid drive pulses, Figs. 2, 3, and 4 are front views showing an example of the head retraction mechanism. They are a side view and a perspective view of essential parts. In the figure, 1 is a thermal head, 2 is a platen, 3 is a pressure spring, 4 is a first solenoid, 5 is a plunger, 6 is a second solenoid, 7 is a spring, 8 is a latch lever, 9 is a latch mechanism base, and 50 is a plunger. It's a groove.

励磁させることを特徴としたサーマルプリンタ。 A thermal head is movably supported so that it can be positioned in two positions, a printing position in contact with the platen and a non-printing position away from the platen, and a latch mechanism is provided between the base and the thermal head to move the thermal head to the printing position. a first solenoid which is rotatably attached to the latch mechanism base and which is rotatably attached to the latch mechanism base and which is connected to the thermal head and which moves the thermal head to a non-printing position via a plunger having a groove at the rear; a latch lever that engages with a groove of the plunger to prevent movement of the plunger when the head is in a non-printing position; a spring that biases the latch lever in a direction to engage the groove; and a spring that urges the latch lever to move away from the groove. a second solenoid for moving the thermal head in the printing position, and the first solenoid and the second solenoid are energized almost simultaneously when the thermal head is returned to the printing position.
