Abstract

PURPOSE:To provide an etching device in which there are provided a pair of guide plates for reversing a master, a tank of etching liquid, a liquid suction roller, and a pair of squeezing rollers etc., and an etching liquid is not coated on a back surface of a master paper. CONSTITUTION:A master paper fed by the front feeder rollers 1 and 2 is guided by a guide plate 5 and fed to the rear rollers 3 and 4. During this operation, when the guide plates 6 and 7 are moved up by solenoids, the master paper is reversed by the guide plate 6 with its front surface being directed down, then fed between the sliding contact surfaces of the liquid suction roller 10 and the pressing roller 11 arranged in the etching liquid tank 9, and some etching liquid 8 is coated on a surface of the master paper. Then, the paper is squeezed by the squeezing rollers 12, 13, passed through the guide plate 14, feeder rollers 15, 16 and reversed by the guide plate 7 and turned back to the front feeder rollers. Further, when the paper is transported to the rear feeder rollers 3 and 4, the guide plate 6 is moved down and discharged out of the system.
