Abstract
PURPOSE:To prevent the occurrence of frame-form unexposed portions at the end parts and both side parts of photosensitive paper through simple operation of thurning a knob by the simple constitution of providing end exposure lamps and shield plates as well as side exposure lamps and shield plates. CONSTITUTION:When at the time of setting the magnification of the copying apparatus a shield plate 23 is set at an optimum angle by turning a dial knob 29 if necessary, then the side exposure lamps 31 and shield plates 41 are moved to suitable positions by the movement of a wire 36. When photosenstive paper 19 is fed by operation of a print button, the side exposure lamps 31 go on to expose both side parts of the photosensitive paper 19. Upon stopping of the photosensitive paper 19 in the exposure position, the side exposure lamps 31 are put out and the image exposure by the exposure light souce 10 and the exposure by the exposure lamps 22 are accomplished.
