摘要：
The present invention relates to a ribbon feed mechanism for use in a heat transfer printer. The ribbon feed mechanism includes first, second, and third ribbon feed components (53, 55, 54) fitted on a shaft (60), a friction plate (56) mounted between the first and second ribbon feed components (53, 55), a spring (57) mounted between the second and third ribbon feed components (55, 54), a cylinder which is in contact with the third ribbon feed component (54) at one end thereof, and a ribbon feed presser (65) for pressing the other end of the cylinder (66) toward the third ribbon feed component (54). The rotational torque is always kept constant, and therefore no unmatching of colors occurs when the mechanism is applied to a printer.
