PURPOSE:To simplify a position adjusting mechanism and secure the correct supply of plate information by storing a function part to control a plate in a plate cylinder and providing a system to receive and send control signals to and from the function part by light-electricity converters placed at the external parts corresponding to the shaft ends of the plate cylinder. CONSTITUTION:Driving signals of a position adjusting mechanism for a plate cylinder and signals of plate information are supplied by a programmable computer 20 and fed and fed back through the first light-electricity converter 21 on the side of a frame 1 and the second light-electricity converter 22 incorporated in the end of a retaining shaft 2b of a plate cylinder 2. An input and output device 23 which sends and receives signals to and from the second light- electricity converter 21 is provided inside the plate cylinder 2 and a control system which inputs controller signals of the plate position adjusting mechanism therefrom. A driving motor is provided in the plate cylinder 2 itself to adjust the position of an outer sleeve and an internal space is used for storing the driving mechanism. |
