ISOLATION OF DISTURBANCE IN BELT PHOTOSENSITIVE BODY OF COLOR PRESS

摘要

PURPOSE: To isolate the disturbance of impact and high-frequency force generated by the fact that a recording medium is delivered in the transfer nip of a transfer part by a belt photoreceptor module for a color printing machine. CONSTITUTION: A belt photoreceptor 12 arranged around plural rollers set by leaving an interval is included in the belt type photoreceptor module 10. The transfer part 14 is arranged by being adjacent to the photoreceptor 12 part. Besides, the tension rollers 22 and 24 are arranged on both sides of the transfer part 14 by being adjacent to the photoreceptor 12. The respective tension rollers are linked around a proper shaft so that the photoreceptor 12 can be delivered to the next roller by the angle of about 90 deg. with respect to the shaft without generating lateral force. The respective tension rollers are set so that they can be moved along different lines and tension levels mutually different from the other is generated inside. The tension level generated by the tension roller is not substantially changed. Therefore, the disturbance of the impact and high-frequency force is reduced.
