A CPU provides a fluorescent light detecting head with an irradiation instruction, in response to which the fluorescent light detecting head irradiates an ultraviolet ray for detection on an ultraviolet curing resin material to be examined. The CPU then acquires from the fluorescent light detecting head an intensity of a fluorescent light emitted from a photo polymerization initiator included in the ultraviolet curing resin material when receiving the ultraviolet ray for detection. The CPU retrieves a predetermined number of past data of the intensity of the fluorescent light from a storage unit and performs a (moving) average calculation processing to calculate the intensity of the fluorescent light at the current time. The CPU performs an estimation processing of a state of the ultraviolet curing resin material based on the calculated intensity of the fluorescent light.

Method for estimating state of ultraviolet curing resin material

A photoelectric sensor includes: a light projecting section projecting detection medium light to a detection object region; and a light receiving section receiving reflecting light or transmitted light from the detection object region, the sections being in a single piece or in separate pieces. The light projecting section includes: a light source generating the detection medium light; and a light projecting lens for collimating or collecting the detection medium light from the light source to form a beam spot or a light collecting point in the detection object region. The light projecting section further includes: a deflection angle adjusting unit capable of finely adjusting an optical axis deflection angle of the detection medium light projected to the detection object region from the light projecting section.
