Claims

[Scope of Claim for Utility Model Registration] Plate cylinders that are provided in each of a plurality of printing units and can be rotated and stopped in conjunction with each other, and a plate selected from a desired plate cylinder and at a stopping position where it is easy to install the printing plate. An operating switch that commands the cylinders to stop, a single sensor that detects the rotational position of the plate cylinders, and a power supply that rotates each plate cylinder at a slow and constant speed when the desired plate cylinders are aligned. A driving motor, a stopping means that is started when the motor is de-energized and stops the rotation of each plate cylinder, and a stop that makes it easy to install the printing plate when the rotational position of the plate cylinder is detected by a sensor when the motor is energized. a time setting means for pre-measuring the differential time for each printing plate until it reaches a position, setting the measured differential time, and selecting the differential time according to a command from an operating switch; A timer is activated in response to a command and a detection signal of the rotational position of the plate cylinder from a sensor and measures the time, and a timer is activated to measure the time. control means for de-energizing the motor and activating the stopping means when the differential time set in the time setting means matches the time measured by the timer. Characteristic sheet-fed printing press.
