<p>PURPOSE:To facilitate correcting work for an image part in a state where printing ink is not perfectly wiped out, to perform it in a short time, and to prevent image erasing ability from being deteriorated by providing a means for changing image eraser inside a means for storing the image eraser on a printing plate with pressure. CONSTITUTION:The main body 16 of an erasing tool is made cylindrical, and its inside is formed in an eraser chamber 13, then the eraser is held by a porous material. A pen point holder 12 and a pen point 11 are attached to the front end of the main body 16. Furthermore, the rear end of the main body 16 is constituted of a female screw part 14 formed on the inside wall of the main body 16 and a cap 15 whose tip is formed like a male screw. The cap 15 is constituted so that it can move up and down in the axial direction of the main body 16 along the female screw part 14 when it is turned. Therefore, when the cap 15 is rotated to be screwed in the main body 16, the volume of the inside of the main body 16 and the eraser chamber 13 is reduced and the eraser held in the chamber 13 is pressured, so that the amount of the eraser supplied to the pen point 11 becomes large.</p> |
