摘要：
A band detection sensor includes LEDs configured to radiate detection light onto one side of a web, photodiodes configured to receive the detection light reflected by the web and output a detection signal corresponding to the detection light, and a discrimination section configured to discriminate bands on the web on the basis of the detection signal from the photodiodes, wherein the discrimination section includes a rise discriminating criterion indicating a rate of rise of the detection signal and generates a band signal indicative of the presence of a band when change of the detection signal fulfills the rise discriminating criterion.
