、装置全体が複雑かつ高価になってしまう欠点がある。(Problems to be Solved by the Invention) In the above-mentioned conventional technology, the presence, amount, size, etc. of the fluorescent light emitting material is detected by irradiating the fluorescent light emitting material with ultraviolet rays to cause it to emit light, and detecting the amount of light emitted. Therefore, it is necessary to distinguish between fluorescent light emission and disturbance light. Therefore, when visually inspecting, it is necessary to work in an environment such as a dark room where there is no influence of ambient light to some extent, which inevitably results in expensive equipment. In addition, workers must continue to look at weak light due to the negative effects of dark rooms, etc., which is unfavorable from an environmental and sanitary perspective, and since it is difficult to work on the machine, inspection must be performed in a separate process. In addition, when detecting using a light receiving element or camera, the detection device and object to be detected are housed in a light-shielding box to completely block external light, and the light source is equipped with a light source to remove visible light components. Since it is necessary to provide a filter, etc., there is a drawback that the device becomes large and expensive. Furthermore, rather than completely removing ambient light, it is possible to reduce the effect of ambient light to some extent by installing a filter on the light-receiving element side or making improvements to the circuit, but in this case, the effect of ambient light is weak to begin with. This method has the disadvantage that the entire device becomes complicated and expensive because the fluorescence emission must be detected by further weakening it.

ば硫化亜鉛カドミウム等を使用してもかまわない。The ultraviolet absorber detection device has been described above based on one example, but for example, by combining a commercially available photoelectric switch or rotary encoder with the ultraviolet absorber detection device, it is possible to detect the amount of glue in a can making machine or a bookbinding machine. You can also
It is also possible to use a dispenser or the like as a gluing device and control the amount of gluing based on the signal from the ultraviolet absorber detector. In addition, when detecting objects that are coated, attached, or printed on something that transmits ultraviolet rays, such as a transparent film,
By detecting the amount of transmitted ultraviolet rays, it is also possible to detect the presence or absence or size of the ultraviolet absorber. In addition, 2-(3'-5'-alkyl-
2-hydroxyphenyl)benzotriazole or 2.2°-dihydroxy-4-methoxybenzophenone may be used, or a commercially available fluorescent material such as zinc cadmium sulfide may be used.
