When the film moves to the lower side of the print head 9, the servo motor 10 starts to run through the regulation of the single-chip microcomputer 2. The servo motor 10 drives the winding roller 8 to rotate. Because the carbon ribbon of the carbon ribbon roll 7 is usually in contact with the lower side of the print head 9 and then wound around the outside of the winding roller 8, the winding roller 8 can drive the carbon ribbon to move during the rotation.

During the operation of the self-service film automatic printer, the external device transmits the CT image data to be printed to the single-chip computer 2 through the data interface 17.

[0037] The working principle of a self-service film automatic printer provided by the present invention is as follows: during the operation of the self-service film automatic printer, the external device transmits the CT image data to be printed to the single chip microcomputer 2 through the data interface 17, and the single chip microcomputer 2 transmits the received data to the print head 9, and then the user puts the film into the inside of the conveying slot 3, and then the user presses down the trapezoidal block 57, and the trapezoidal block 57 moves downward along the inner wall of the fixed plate 54 through the baffle, and the reset spring 56 extends. When the trapezoidal block 57 coincides with the avoidance groove, the torsion force generated by the rotation of the torsion spring 59 is transmitted through the mounting rod 5 2 drives the guide box 53 to rotate forward and reset, thereby unfolding the guide box 53. Then, through the control of the single chip computer 2, the conveying motor 12 starts to run, and the conveying motor 12 drives the conveying roller 11 to rotate.

When the carbon ribbon with the toner coating moves to the lower side of the print head 9, the print head 9 starts to run through the regulation of the single chip microcomputer 2. The print head 9 heats the toner coating on the carbon ribbon and transfers it to the film, thereby realizing the printing work on the film. The printed film will move to the inside of the guide box 53. Finally, the user can take out the printed film. During the movement of the film, the adjustment motor 16 starts to run through the regulation of the single chip microcomputer 2. The output shaft of the adjustment motor 16 drives the screw 15 to rotate. The screw 15 drives the adjustment plate 13 through the threaded connection during the rotation. Move backward, the adjustment plate 13 drives the transmission plate 46 to rotate backward with the vertical rod 45 as the center through the push rod 14. During the rotation of the transmission plate 46, the adjustment rod 47 slides inside the adjustment groove and rotates relative to the adjustment groove, so that the adjustment rod 47 drives the connecting plate 42 to move, and the spring 48 extends. The connecting plate 42 and the vertical plate 43 drive the limit plate 44 to move toward the end close to the center of the body 1. Finally, the limit plate 44 contacts the left and right ends of the film, thereby limiting and guiding the film to prevent the film from being displaced during the movement and affecting the final printing effect.
