PURPOSE:To separate the uppermost printing original plate from an original plate below it completely by lifting one end side of a printing original plate by a suction rubber and rotating a support bar from one end side of the reverse surface of the original plate to the other end side. CONSTITUTION:This is the device which manufactures a printing plate from a printing original plate 52 provided with a photosensitive layer by an electrophotographic method and provided with a device which supplies original plates 52 stacked in a cassette 61 separately, sheet by sheet. Here, this supply device is provided with suction rubber 62 and the support bar 108 which is fitted to the rotary solenoid 109 of a cassette base 102 and rotatable by 90 deg.. Then the rubber 62 sucks and lifts the left-end side of the uppermost original plate 52 and then the bar 108 moves from the reverse surface of the left-end side to the right side, thereby separating the upper original plate 52 completely from the lower original plate. Then the original plate 52 is drawn in between rollers 63 and 64 and sent to an electrostatic charging device. |
