PURPOSE:To obtain a plate cylinder support device in which a drum can be easily released from positioning and pulled out by a simple operation, that a plate cylinder device is locked is not detected unless it is completely locked to a frame, and there is no possibility of erroneous detection caused by a vibration during printing or other factors. CONSTITUTION:A plate cylinder device 80 is detachably loaded on a frame. A locking pin 72 is fixed to the frame. An arm 73, a stopper 74, and an unlocking lever 75 are each rotatably mounted on the plate cylinder device 80. When the plate cylinder device 80 is loaded on the frame, the arm 73 abuts against the locking pin 72 and rotates about locking pin 72. Then, the upper part of the arm 73 is fastened to the stopper 74. The plate cylinder device 80 is locked to the frame. By rotating the unlocking lever 75 in this state, the stopper 74 is moved to an unfastening position. Then, the fastened state of the arm 73 by the stopper 74 is released, the arm 73 is rotated, and the locked state of the plate cylinder device 80 to the frame is released. |
