とを備えたことを特徴とする不正給紙検出装置。A light-emitting element and a light-receiving element are provided near the front of a feeder board of a sheet-fed printing machine to detect whether the improper feeding of sheets is large or small, and the improper feeding is detected based on the detection power of the light-receiving element. When the paper condition is large, a side extraction signal is sent in synchronization with the operation of the printing press, and when the improper paper feeding condition is small, the sheet is ejected in a special condition in synchronization with the operation of the printing press. A control circuit for transmitting a control signal to detect unauthorized paper feeding.
