Abstract

PURPOSE: To make it easy and secure to separate a transfer material during transcription and transcribing-material conveyance, by curling only its tip by using a couple of rollers.
CONSTITUTION: In front of the place where transfer paper enters transferring part A, curling method 3 is provided which consists of upper roller 8 made of an elastic body and lower roller 9. Solenoid 10 is fixed on the upper roller 8. As the transfer paper enters transferring part A, a prescribed detection signal puts solenoid 10 into operation to turn elastic roller 8 in pressure contact with roller 9, thereby curling the paper. Solenoid 10 is turned off a fixed time later and then while no pressure is applied, rollers are turned. Consequently, only the tip of the paper is curled and the transferred paper is separated from drum 1 easily and securely at charge removal part B by the weight and elasticity of the paper.
