PROBLEM TO BE SOLVED: To easily and surely wash porous and non-porous printing bodies by installing at least three sets of upper and lower washing rollers disposed at a U-shaped machine body, immersing these upper and lower washing rollers into a washing liquid and repetitively moving a printing body sheet inscribed with a printing surface back and forth between the upper and lower washing rollers. SOLUTION: A motor 2 is disposed in the upper part of the U-shaped machine body 1 and the opposite surfaces of the U-shaped machine body 1 are provided with, for example, three sets on the upper and lower washing rollers 3 horizontally in juxtaposition at specified intervals. The upper and lower washing rollers 3 are constituted by perpendicularly installing the respective upper and lower washing rollers 4, 5 in juxtaposition, meshing the rollers with each other by means of gears 6, rotating the rollers via a chain 9 by means of the motor 2 and bringing the rollers into pressurized contact with each other by means of repulsive members. The entire part of the upper and lower washing rollers 3 is immersed into the washing liquid in a water tank 14. A printing body 17 subjected to printing surface processing is inserted between the upper and lower washing rollers 3 from one receiving plate 18 and is subjected to rubbing and washing by reciprocating motion. The printing body 17 is thereafter discharged from the upper and lower washing rollers 3 and is received by another receiving plate 18.
