  • Exposure Or Original Feeding In Electrophotography (AREA)

Abstract

PURPOSE:To obviate the formation of latent images at the time other than original exposure on a drum and enable drum surface charges to be removed at the exposure of a blank by opening and closing the shutter in synchronization to the reciprocatively moving means of the original images. CONSTITUTION:This is provided with a light source 6 which is provided along the revolving shaft direction of a drum 1a, a shutter 6 which is provided between the light source 6 and the region where the original images are exposed on the drum 1a, a reciprocatively moving means 20 which operates so as to slit-exposes the original images on the drum, a pulley 18 which is changed over of its revolving directions in synchronization to the reciprocatively moving directions of the means 20 and an oscillating plate 22 which is so mounted to the pulley 18 as to open and close the shutter 16 according to the turning direction changes of te pulley 18, wherein when the original images are not exposed on the drum 1a the shutter is held in the open position to radiate light from the light source 6 onto the drum 1a so that the potentials of the drum 1a are maintained at a non-developing potential.
