<P>PROBLEM TO BE SOLVED: To simplify a structure, to reduce manufacturing cost and also to reduce an installation space, without increasing the number of components. <P>SOLUTION: An impression cylinder gear 5a is engaged with an offset cylinder gear 6a to keep the offset cylinder gear 6a engaged with a plate cylinder gear 7a. An offset cylinder 6 is supported rotatably by a frame through the medium of an eccentric bearing 14, and throwing-in and throwing-off of an impression cylinder 5 and a plate cylinder 7 are performed by a cylinder attaching-detaching device 12 which rotates the eccentric bearing 14. The cylinder attaching-detaching device 12 is operated to make the offset cylinder gear 6a roll around the impression cylinder gear 5a with the rotation of the impression cylinder gear 5a regulated, so that the plate cylinder 7 is set at a fixed position. <P>COPYRIGHT: (C)2009,JPO&INPIT |
