Claims

[Claims for Utility Model Registration] A platen 21 and a thermal print head 22 are arranged opposite to each other across a card conveyance path, and the thermal print head is applied to the platen with a prescribed pressure necessary for printing only during the printing operation on the card. In the print head pressurizing device for a card printer, which is energized by a lever member 27 rotatably supported on a moving shaft, the other end of which is pivotally supported on both sides of the thermal printing head, for moving the thermal printing head toward the platen;
A pressurizing spring member 26 that urges the thermal print head toward the platen with the specified pressure and a plunger 28a are fixed to the mounting frame so that the moving direction thereof is parallel to the thermal print head, and when a print end signal is received. A solenoid 28 is attached to the tip of the plunger in a direction perpendicular to the direction of movement of the plunger, and a solenoid 28 is attached to the tip of the plunger in a direction perpendicular to the direction of movement of the plunger, and the solenoid 28 is attached to the tip of the plunger in a direction perpendicular to the direction of movement of the plunger. As a result, the tip of the shaft rod 2 comes into contact with the lever member and urges the lever member from above to separate the thermal printing head from the platen.
9, inclined guide windows 30a and 30b are provided on the outer peripheral surface of the plunger and rotate the shaft rod in a direction in which the lever member is urged upward as the plunger moves backward. A printing head pressurizing device for a card printer, which is equipped with a guide tube 30 that has a guide tube 30.
