Claims

[Scope of Claim for Utility Model Registration] A paper detection means is disposed on a paper feed system path near a plate cylinder around which a plate-making base paper is wound, and printing paper is sent by a feed roller of the paper feed system. contacting the lever of the paper detection means, and the operation of the paper detection means causes a press roller provided below the plate cylinder to be pressed against the plate cylinder, thereby printing on the printing paper. A base of the paper detection means is rotatably attached to a drive shaft that drives the feed roller, and a tip of the lever whose base is fixed to the base is positioned on the path of the paper feeding system. A switch is disposed at a position facing the lever to operate a mechanism for pressing the press roller in the direction of the plate cylinder, and the printing paper passing on the path comes into contact with the tip of the lever. A paper detecting means for a rotary copying machine, characterized in that the lever closes the switch.
