Claims

[Scope of utility model registration request]

A paper feeding mechanism unit configured such that two sets of paper feeding rollers each having a cylindrical surface made of an elastic body with a high coefficient of friction are each driven synchronously by a drive motor controlled by a recording paper feeding control signal. and a recording plane part made of an elastic body with a smooth surface, located between the two sets of paper feed rollers, and in a plane where the surface of the recording plane part is in contact with the cylinders of the two sets of paper feed rollers. a flat platen located at the
a platen mechanism section comprising an adjustment mechanism for adjusting the attitude of the planar platen; a rectangular thermal head in which heating resistors are arranged one-dimensionally on a smooth ceramic substrate; and the thermal head. a pressure mechanism for pressing the surface of the heating resistor of the thermal head with an optimum pressure against the surface of the recording paper on the recording plane portion of the flat platen; A transfer ink film coated in a plurality of colors is maintained between the thermal head and the recording paper, and the distance between the heating resistor of the thermal head and the position at which the transfer ink film that is in close contact with the recording paper is peeled is set. A carriage that is equipped with a peeling mechanism that is always maintained constant and is driven by a control motor on a guide shaft that is perpendicular to the recording paper feeding direction and parallel to two sets of paper feeding roller shafts and the recording plane part of a flat platen. a mechanism section, a removable cutter equipped with a reel wound with the transfer ink film, and a seven-meter sensor for identifying the color of the transfer ink film;
a one-way rotation mechanism section that is located at substantially symmetrical positions via the reel and the carriage mechanism section and drives the transfer ink film in one direction according to an input control signal and the sensor output signal; In the thermal transfer printer, the carriage mechanism is configured to include a pressure mechanism that can apply pressure to the surface of the recording paper during recording, and a return mechanism that can separate the carriage mechanism from the surface of the recording paper when the carriage mechanism returns. A set of cylindrical surfaces provided in the mechanism section are made of an elastic body with a high coefficient of friction, and the carriage mechanism section is brought to the recording start position by a transfer ink film holding roller that pinches the transfer ink film and can only rotate in one direction. A thermal transfer printer characterized in that it is equipped with a transfer ink film feeding mechanism that pulls out the transfer ink film and installs a new transfer ink film so that it comes into contact with the recording paper when returning.
