ABSTRACT:
An image position adjusting device for controlling an imaging area in a longitudinal direction of a printing sheet. This position control is made by rotating one of the impression and blanket cylinders with respect to the other. A first intermediate gear is mounted on a shaft extending between the side frames of the printing machine, and a second intermediate gear is engaged with the first intermediate gear and a stationary gear of one of the impression and blanket cylinders. The second intermediate gear is swingable while meshingly moving along the first intermediate gear for rotating the gear of the impression or blanket cylinder. During movement of the second intermediate gear, it is always held between the first intermediate gear and the stationary gear.
