Cropmark detection device and cutting device equipped with it

摘要

PROBLEM TO BE SOLVED: To improve detection accuracy while suppressing an increase in cost of a cropmark detection device. SOLUTION: A light emitting device 57 that irradiates light toward a media 5, a receiver 58 that receives the reflected light from the media 5, and a receiver 58 receives a large amount of light within a range of a predetermined power supply voltage or less. It includes an output circuit 22 configured to output a high voltage, and a detection circuit 28 that determines whether or not the output voltage of the output circuit 22 is below the threshold value and detects the crop mark 8 when the output voltage is below the threshold value. ..
