加圧装置。[Claims for Utility Model Registration] (1) 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 specified pressure necessary during printing operation on the card. A printing head pressurizing device for a card printer that urges the card includes a mounting plate 23 that is arranged parallel to the card conveyance path and has a rotation shaft 24 at one end, and a mounting plate 23 that is arranged above the mounting plate. a lever plate 25, one end of which is rotatably supported by the rotation shaft of the mounting plate, and the other end of which is pivotally supported on both sides of the thermal printing head to move the thermal printing head toward the platen; A movable member disposed above the lever plate, one end of which is rotatably supported by the rotation shaft of the mounting plate, and the other end of which is formed with a convex portion that selectively abuts the upper surface of the mounting plate. 26 is inserted between the movable member and the mounting plate, and urges the movable member in the direction of the mounting plate with the prescribed pressure while the convex portion is in contact with the upper surface of the mounting plate. The pressure spring members 27a, 27b and the plunger 28b are attached to the movable member so that the moving direction of the plunger 28b is in the direction of the thermal printing head, and the plunger is moved back and held in response to the printing start signal, and is held in the printing end signal. A solenoid 28 whose lever holding state is released, a substantially central portion of which is pivoted to the movable member, an upper end of which is pivoted to the tip of the plunger, and a lower end of which engages the lever plate in response to the retreating movement of the plunger. a rotating lever 29 that urges the thermal printing head downward to move the thermal printing head toward the platen; and a rotating lever 29 that is wound around the plunger and moves the plunger forward during the holding state release period to rotate the rotating lever. and a plunger spring 31 which urges a protrusion formed on the lever plate upward at the lower end of the rotary lever to separate the thermal printing head from the platen. Print head pressure device. (2) The solenoid is composed of a latching solenoid in which a permanent magnet 32 is incorporated, and the lever plate is biased upward by the biasing force of the plunger spring during the holding state release period. 2. The printing head pressurizing device for a card printer according to claim 1, wherein the printing head pressurizing device for a card printer attracts and holds a protruding portion of the printing head.
