Abstract

A thermal transfer machine comprising a freely rotatable belt attachment roller onto which an endless belt can be removably attached with the surface to be imprinted facing outwardly, a freely rotatable thermal roller placed so as to be movable toward and away from said belt attachment roller, a pair of support arms placed parallel to each other across an open space so that said thermal roller is positioned between them, and a marking paper support which has securing fixtures for stretching the marking paper across the space between the support arms and which is capable of moving in a reciprocating motion in the front-to-back direction of the thermal roller. With said thermal roller pressed against the belt on said belt attachment roller by a pressing apparatus, the marking paper support is moved at the same speed as the peripheral velocity of the thermal roller in the direction of the tangent of the thermal roller occurring at the contact surface between the thermal roller and the belt by the drive apparatus which turns the thermal roller.
