Claims

[Scope of utility model registration request]

A thermal head having a heating element that selectively generates heat in accordance with image information is movably supported, and this thermal head is brought into pressure contact with a back roller, and a recording paper and an ink donor film are placed between the thermal head and the back roller. The ink from the ink donor film is transferred to the recording paper to record an image by causing the heating element of the thermal head to generate heat according to the image information, and the moving speed of the recording paper is detected by the detection means. In a transfer type thermal recording device that controls the image recording speed,
A transfer type thermal recording apparatus, characterized in that the thermal head is supported movably in a direction perpendicular to a straight line connecting the detection means and an image recording section of the thermal head.
