ンタの紙送り機構。In a thermal printer in which a platen that presses against a printing section of a thermal head and rotates in the forward and backward directions transports paper between the platen and the thermal head in the forward and reverse directions, on both sides of the printing section, the A pair of rollers movable in a direction perpendicular to the axis of the platen along the surface of the thermal head are disposed so as to be able to press against the platen through the paper, and the rollers are moved evenly in a direction close to each other. A paper feeding mechanism for a thermal printer, characterized in that a paper feeding mechanism for a thermal printer is provided, the paper feeding mechanism being provided with a biasing means that biases the paper so that the paper is brought into pressure contact with the platen.
