Fluid motors eliminate the electrical wiring problems and often have comparatively longer life cycles, but they too have had drawbacks associated therewith. Even with so-called frictionless diaphragm-type fluid motors, the actuator rods thereof are engaged by bearings, seals and wipers that still hinder free linear movement of the rods. Also, to reduce friction, the rods are made of hardened steel as opposed to less expensive materials.

Field of the Invention
The present invention relates to a heat transfer image-receiving sheet. More particularly, the present invention relates to a heat transfer image-receiving sheet which is highly releasable from a heat transfer sheet without being thermally fused therewith when an image is formed and on which a deeply-dyed image can be formed.

Heretofore, a variety of heat transfer printing methods have been known. One of them is a method in which a sublimable dye is thermally transferred from a heat transfer sheet in which the sublimable dye is supported as a recording agent on a substrate sheet such as a polyester film to an image-receiving sheet capable of being dyed with the sublimable dye, prepared, for example, by providing a dye-receiving layer on paper or a plastic film, thereby producing various full-colored images on the image-receiving sheet.
In the above printing method, the thermal head of a printer is employed as a heat application means, and a large number of dots in three or four colors, the amount of heat applied thereto being properly controlled, are transferred to the image-receiving sheet in an extremely short heat application time. A full-colored original image can thus be successfully reproduced by the multicolored dots on the image-receiving sheet.
The above-obtained image is very sharp and excellent in transparency because a dye is used as the recording agent. The printing method of this type can thus produce an image excellent in the reproduction of half-tones and also in gradation, comparable to an image obtainable by conventional offset printing or gravure printing. Moreover, the quality of the image is as high as that of a full-colored photograph.

Even with so - called frictionless diaphragm - character fluid motors, the actuator rods thereof are engaged by carriage, seals and windshield wiper that still hinder complimentary linear movement of the rods. Also, to abridge friction, the rods are made of hardened sword as opposed to less expensive material. These fluid motors may require pressurization of both side of the diaphragm as well, thereby creating a need to seal all access opening in the motor and further hindering the motion transfer. 1.
