Abstract: In the present invention, the pressure between the paper feed roller and the trailing roller can be changed while preventing possibility of human misoperation and without requiring exclusive motors. The paper support pressure between a paper feed roller and a trailing roller for clamping and conveying paper is changed by a friction switching mechanism. The drive force of a paper feed motor 60 for driving the paper feed roller is transmitted to said friction switching mechanism via a clutch mechanism C1.

When the ribbon driving motor 38 drives in reverse (anti-clockwise direction), an interlinked fan-shaped gear 94 rotates clockwise, a connecting bar 95 is displaced causing a cam 97b to also be displaced resulting in a pinion 63b and gear 72 to be engaged and interfitted with the clutch mechanism C1.

The drive station repeatedly advances receiver paper back and forth through the printing station in conjunction with the advance of successive thermal transfer donor dye colors on a carrier web through the printing station to successively print the different color separations. The platen drum in the printing station is coupled to a platen drag force mechanism for imparting reverse torque to the torque imparted by the drive station to impart a degree of tension to the receiver paper as it passes through the printing station that exceeds stick/slip variations in movement of the receiver paper therethrough by the sublimation of the dyes from the donor dye carrier web to the receiver paper in the creation of the image thereon. The platen drag force may be effected by overdriving a motor or generator or drag brake coupled to the platen drum.
