PURPOSE:To discriminate the presence or absence or quantity or size of a UV absorber or phosphor by irradiating a material to be detected with light and detecting the quantity of the light which is not absorbed by the UV absorber or phosphor. CONSTITUTION:A UV detector is set to a gathering machine and glue 30 previously added with the UV absorber is put into a glue coater. An operator turns on a power supply switch 16 provided to a device body 10 to start the UV detector at the time of operating the gathering machine. The glue 30 is coated by the glue coater on continuous paper 21A delivered from a roll. The light KL which is emitted from a UV source 1 and is reflected by the paper surface or the glue 30 is detected. The result of the detection is inputted via an analog signal amplifier 3 to the device body 10 and is processed by an A/D conversion part 11, a computer 12 for control and an alarm device 13. A lamp 18 of an operation part 14 is lighted to indicate that the gluing condition is good. Defective gluing of the paper 21A is detected 2 and alarmed 15 when such defect arises.
