PROBLEM TO BE SOLVED: To provide a registering device for enabling registering at the same speed as a printing speed by a general-purpose camera having low throughput.SOLUTION: The registering device includes an imaging camera 6, an absolute encoder 5 disposed on a slab axis of a plurality of plate cylinders 4 to detect the position of the slab axis, an image processing trigger pulse generation part 7 for outputting an imaging trigger pulse to the imaging camera 6, an image processing part 8 for acquiring an image picked up by the imaging camera 6 and calculating the existence/absence of a register mark and a distance from a reference point of a window of the register mark, a phase deviation amount operation part 9 for operating the position deviation amount of each of a plurality of plate cylinders 1, 2, 3, 4, and a plate cylinder unit position control mechanism 10 for receiving the position deviation amount operated by the phase deviation amount operation part 9 to correct the position of each of the plurality of plate cylinders 1, 2, 3, 4. The image processing trigger pulse generation part 7 shifts the resolution of the absolute encoder 5 by one at a time to generate an imaging trigger pulse each time the absolute encoder 5 performs one rotation.SELECTED DRAWING: Figure 1 |
