    摘要: A thermal ink-transfer printer for printing a color image on a paper wound along a platen roller in the manner where a thermal head is pressed against the paper and an ink film interposed therebetween so that ink on the ink film is melted by the thermal head. The printer comprises clamp mechanisms having supporting rings and clamp levers for holding an end of the paper against a holding member, clutch mechanisms having clutch rings and clutch levers for fixing the clamp mechanisms and platen roller in a start positioning mode and a printing mode, and a controlling element for coupling the clutch mechanisms with the platen roller in a paper feeding mode and a paper ejecting mode. As the clamp mechanisms hold the supplied end of the paper and the platen roller and the clamp mechanisms have their rotation individually controlled, it is possible to prevent color off-registration in color printing.
