PURPOSE:To enable the printing of many print sizes without paper masks by holding print paper on an exposure table by the suction force of a suction fan. CONSTITUTION:When a suction fan 4 is started, the air before a vertical guide plate 1 is sucked backward of the plate 1 through small holes 2 for ventilation. Opening/closing guide plates 5, 6 are held closed prior to exposure, and print paper is supplied to the guide passage 11 of the exposure table. The print paper is sucked to the plate 1 by the fan 4 when said paper is conveyed. The paper is conveyed up to the exposure position. A forward turning disc 35 turns clockwise to open the plates 5, 6 fully. The paper in this stage is sucked and held to the plate 1 by the suction force of the fan 4. The paper is exposed in this state, and after the exposure, the disc 35 turns counterclockwise to close the plates 5, 6, thereby restoring the state of the figure. |
