Abstract
An exposure device effects a slit exposure to a photosensitive sheet material moving over an exposure station, and includes two pairs of conveyor rollers disposed on opposite sides of the exposure station. The two pairs of conveyor rollers first convey a photosensitive sheet material forward, passing over the exposure station until one of the two pairs of conveyor rollers holds the trailing end of the photosensitive sheet flat therebetween. Prior to making an exposure, the two pairs of conveyor rollers are rotated in a reverse direction to move the photosensitive sheet back. After the trailing end of the photosensitive sheet is grabbed by the other of the two pairs of conveyor rollers, a shutter is actuated to effect an exposure to the photosensitive sheet with a slit line exposure light while the photosensitive sheet is being moved back, trailing end first.
