Claims

[Scope of utility model registration request]

a paper feeding mechanism section 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 driven in synchronization by drive motors each controlled by a recording paper feeding control signal; , including a recording plane 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 plane part is located in a plane that contacts the cylinders of the two sets of paper feed rollers. a platen mechanism section composed of a planar platen and 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; an adjustment mechanism for adjusting the attitude of the thermal head, and a pressure mechanism for applying optimum pressure to the surface of the heating resistor of the thermal head to the surface of the recording paper on the recording plane portion of the flat platen; , a position where a band-shaped transfer ink film coated in a plurality of colors is 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 peeled off. It is equipped with a peeling mechanism that always maintains a constant distance from A driven carriage mechanism, a removable cassette with a reel wound with the transfer ink film, a sensor that identifies the color of the transfer ink film, and a substantially symmetrical cassette that is connected to the reel and the carriage mechanism. A one-way rotation mechanism is located at a position 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 is configured to apply pressure to the surface of the recording paper during recording. and a return mechanism section that can separate the carriage mechanism section from the surface of the recording paper upon return, the thermal transfer printer being capable of pressurizing the thermal head against the surface of the recording paper. The mechanism for releasing the recording paper from the surface of the recording paper at the time of return consists of a rotating shaft having a pair of two planes with slopes at both ends at the center of the axis and an R-shaped ridge of the two planes, and a rotating shaft at both ends of the rotating shaft. Equipped with a rotatable support bearing link,
Moreover, one end is provided with a convex cam having grooves or notches equally divided on the outer edge of the cylinder, and the groove or notch of the convex cam is provided at one end with a semicircular diameter slightly larger than the outer diameter of the convex cam. The thermal transfer device is characterized in that it is equipped with a thermal head pressurization return mechanism consisting of a claw having a protrusion that can be inserted into the head, and an arm that is rotatably attached to a disk provided at the other end of the drive motor. formula printer.
