摘要

PROBLEM TO BE SOLVED: To prevent the generation of exclusive large moment load by simplifying the application state of force for a deck of a printer having a common impression cylinder. SOLUTION: A deck for a printer with a common impression cylinder 42 is provided with a plate roll 48 and an annex roll 49 for moving linearly one unit of linear rails 54 and 55 disposed in parallel at an interval. The plate roll 48 and the annex roll 49 are moved respectively along the linear rails 54 and 55 by rotatable ball screws 78 and 88. The axial centers of the ball screws 78 and 88 cross substantially the axial centers of the plate roll 48 and the annex roll 49.
