Claims (1)

[Scope of utility model registration request] A paper feed mechanism configured such that two sets of paper feed rollers each having a cylindrical surface made of an elastic material with a high coefficient of friction are each driven synchronously by a drive motor controlled by a recording paper feed control signal. and a recording flat part made of an elastic body with a smooth surface, located between the two sets of paper feed rollers, and furthermore, the surface of the recording flat part is in contact with the cylinders of the two sets of paper feed rollers. A platen mechanism section includes a flat platen located within a plane, an adjustment mechanism for adjusting the attitude of the flat platen, and heating resistors arranged one-dimensionally on a smooth ceramic substrate. It includes a rectangular thermal head and an adjustment mechanism for adjusting the posture of the thermal head, and presses the surface of the heating resistor of the thermal head with an optimal pressure against the surface of the recording paper on the recording plane part of the flat platen. A pressure mechanism for the transfer and a belt-shaped transfer ink film coated in a plurality of colors are maintained between the thermal head and the recording paper, and the transfer ink film that is in close contact with the heating resistor of the thermal head and the recording paper is maintained between the thermal head and the recording paper. The ink film is peeled off on a guide shaft that is perpendicular to the recording paper feed direction and parallel to two sets of paper feed roller shafts and the recording plane part of the flat platen. A carriage mechanism driven by a control motor, a removable cassette equipped with a reel wound with the transfer ink film, a sensor that identifies the color of the transfer ink film, and the reel and the carriage mechanism A one-way rotation mechanism that is located in approximately symmetrical positions and drives the transfer ink film in one direction according to the input control signal and the sensor output signal, and a pressure mechanism provided in the carriage mechanism that rotates the recording paper during recording. A thermal transfer printer comprising a return mechanism capable of applying pressure to the surface and separating the carriage mechanism from the surface of the recording paper when the carriage mechanism returns, wherein the reel support mechanism on which the transfer ink film is wound is A cylindrical catch with a notch on the support surface side supported by the cassette, a cylindrical reel support part with a variable outer diameter including an outer diameter that matches the inner diameter of the transfer ink film reel, and a cylindrical diameter contraction. The distal end of the cylindrical catch seat has a tension adjustment arm extending from the circumference of the notch relief section, and has an L-shaped micrometer equipped with a tension coil spring at one end and a guide roller at the other end. A thermal transfer printer characterized by a tension adjustment arm and a rotatable guide roller.
