Thermal transfer type printing apparatus

Abstract

Abstract PURPOSE:To improve printing quality by preventing the generation of wrinkles to transfer paper without altering the constitution of a printing apparatus to a large extent, by additionally providing a guide bar provided with a specific spiral groove in the vicinity of a platen roller. CONSTITUTION:Recording paper 3 and transfer paper 4 are run between a platen roller 11 and a thermal head 2 and a head 2 is selectively heated to transfer the ink of the transfer paper 4 to the recording paper 3. In the above mentioned thermal transfer type printing apparatus, a guide bar 5 having shallow spiral grooves 5', 5' each provided to each oblique half of the axis thereof in a mutually opposed direction is arranged in the vicinity of the inlet side of the transfer paper 4 to the plate roller 1 so as to be made revolvable around the axial core thereof. When stress of a width direction (a C-direction) for generating wrinkles is added to the transfer sheet 4, the guide bar 5 is revolved to select the spiral groove 5' which is, in turn, contacted with the transfer paper 4 to eliminate the above mentioned stress and wrinkle generation is prevented.
