PURPOSE:To simplify a structure of a working floor and reduce a burden of an operator moving between the respective working floors by a method wherein printing means are stacked in a plurality of stages, the working floors are provided to the printing means, and working floor lifting means for lifting/ lowering the working floors are provided. CONSTITUTION:Printing means P stacked in four stages are provided on a lower standard floor F1 through an upper standard floor F2. On the lower standard floor F1, working floors 1 extending in parallel to the axis of a plate cylinder PC are provided on the both outer sides of the printing means P. Working floor lifting means 2 are provided for supportingly lifting/lowering the working floors 1 from under the working floors 1. If the operator is to operate the printing means P of an intermediate stage which is hard to operate on the working floor 1 positioned to be level with the standard floor, the operator stands on the working floor 1 and actuates the working floor lifting means 2. The working floor 1 is stopped when being moved up to a predetermined or appropriate position. Then, at this position, the operator operates the printing means P in a stable posture. |
