PROBLEM TO BE SOLVED: To drive cylinders and each functional group technically without labor by driving by a single motor without using a shaft, a gear device, a coupler, and a gear. SOLUTION: A printing unit is equipped with two printing mechanisms 3, 4 composed of plate cylinders 1.1, 1.2 and rubber cylinders 2.1, 2.2. The plate cylinders and the rubber cylinders 1.1, 1.2, 2.1, 2.2 are born by journals in side walls 5, 6, respectively. Gears 8-11 are attached to a journal born on the side wall 6 respectively, The cylinders 1.1, 1.2, 2.1, 2.2 are driven/coupled with adjoining cylinders and driven respectively by these gears. In this way, the four cylinders are all driven by a motor 7. Namely, all cylinders are driven/coupled with the plate cylinder 1.1 through the gears 8-11 to be driven by the motor 7. |
