Thermal transfer apparatus

Abstract

Abstract PURPOSE:To prevent the generation of wrinkles and density irregularity in copy paper by uniformizing pressure contact force by preliminarily supposing the bending deformation of a platen roller and forming the surface shape of a thermal head so as to follow this bending by a control mechanism. CONSTITUTION:In a mechanism for controlling the surface shape of a thermal head 1 when thermal transfer is performed by the pressure contact of the thermal head 1 with a platen roller 3, a plurality of adjusting rivets 10 functioning as the control mechanism so as to tightly bring the surface shape of the thermal head into contact with the peripheral surface of the platen roller 3 bent and deformed into a bow shape under pressure are mounted.
