Abstract

PURPOSE:To obtain a device permitting a general user to exchange the photoreceptor easily without causing positional deviation, by providing a copying photoreceptor holding means in a cam plate coaxially supported on a drum, and detachably fitting the photorecptor. CONSTITUTION:When a master exchange button is depressed, a drum 18 and a cam plate 19 stop at the master exchange position. Then, the master M is held with a receiving plate 23. Along with the rotation of the drum 18, a mater holding plate 26 rides over the circumference of the drum 18 to press the master M against the circumference of the drum 18. Thus, the master M is, because the cam plate 19 does not rotate, tightly contacted with the circumference of the drum 18 due to rotation of the drum 18 and by means of master holding plate 26 and others. The master is a photoreceptor in electrostatic printing and an original paper for printing in offset printing. In this constitution, a general user can exchange the master easily without causing positional deviation.
