Abstract Topic Continuing, lawn stocks of the artificial lawn which is produced in the band-likeBe able to detect the uneven defect of height securely, furthermore, production kosuThe lawn stocks survey instrument of the inexpensive artificial lawn of to is offered. Solutions The surface of artificial lawn L over the total width raThe cylindrical illuminant which is irradiated to in condition (1), reflected light of line conditionAbsorbing light, photoelectricity it converts the many photosensor which the cylindrical illuminant (1)Paralleling, the line sensor which is arrayed into rectilinear condition (2), thatTo control output timing, at the same time video trust from each photosensorThe driver which converts the number to the respective digital signal (3),On the basis of the digital signal the artificial lawn (L) the reflection which crosses the total widthThe reflected light intensity levelling means which calculate the average of the light intensity (4), averageWhen value is above upper limit or below the lower limit value height of lawn stocksThe uneven defective decision means which output the decision signal of uneven defectThe alarm means which give out alarm (5), according to the decision signal (6)It has.
