Abstract
PURPOSE:To eliminate the scattering of toner sticking on nearby the edge of a blade from scattering around and to prevent the generation of an abnormal image and stain in equipment by putting a solenoid which drives the blade in gradual rising and falling operation through an electric or mechanical operation delay means. CONSTITUTION:A capacitor 5 is connected between the base of a transistor (TR) 6 and the ground and the base current of the TR 6 is increased gradually in response to a solenoid input signal (i), so a driving current supplied to a solenoid 4 increases gradually and the driving force of the solenoid 4 rises gradually as well. Namely, the solenoid output I rises gradually while requiring a prescribed time (t) because of the capacitor 5. When the solenoid output reaches a prescribed value, the output P of the main motor of a copying machine turns on and a photosensitive body 2 begins to rotate. Consequently, when the blade I contacts the photosensitive body 2, the solenoid is driven gradually, so a mechanical shock due to the contacting is suppressed extremely small and the scattering of the toner is suppressed.
