Claims

[Scope of Claim for Utility Model Registration] In a thermal printing device that prints by pressing a printing head onto thermal coloring paper to generate color under heat, a thermal coloring agent coated on the base paper of the thermal coloring paper is installed in the printing head. A heat-sensitive coloring agent removing device is provided at the front in the direction of movement of the heat-generating element array installed in the print head, and the heat-sensitive coloring agent removing device is formed so that more of the coloring agent is scraped off at the contact center of the heat-generating element array and less at the upper and lower portions thereof. type printing device.
