Abstract
PURPOSE:To achieve the miniaturization of the device and perform good exposure by letting a flash light source of exposure emit light at every scanning of the original of a fixed quantity. CONSTITUTION:When the original moves for a fixed quantity together with contact glass 3, it stops. When this stop is detected with a position detector 6, a flash lamp 1 keeps lighting up until it is detected by a photo detector or the like that the specified quantity of light is reached by way of a flash trigger circuit 7 and a flash lighting circuit 8. By the similar reiteration, image exposure is accmplished evenly at large quantity of light irrespective of scanning speed. This constitution makes possible the simple and small size constitution of the exposure device and lets good exposure be accomplished.
