Abstract
A printing plate mounting apparatus is disclosed, which comprises a de-mounting and a mounting lever provided on an end of a lock shaft provided in a printing cylinder and printing plate replacement drive means including air cylinders or the like. With the printing cylinder held at a predetermined position, the drive means pushes each lever to rotate the lock shaft. In this way, the rotational driving of the lock shaft and coupling and de-coupling of the driving are effected collectively. A printing plate replacement apparatus is also disclosed, which comprises roller drive means including a roller and a cylinder or the like. When mounting a printing plate, the roller is urged against the printing cylinder via the printing plate. Otherwise, the roller is retreated by the roller drive means.
