PROBLEM TO BE SOLVED: To improve the inspection accuracy for screws while reducing the fear of increase in inspection time or costs of an inspection device.SOLUTION: A screw inspection device includes: a carrying mechanism 5 which carries a screw B along a carrying path 53 through an inspection position P; a camera which captures an image of an imaging range 61 including the inspection position P; mirrors M1, M2, M3 and M4 distributed on both sides across the carrying path 53 in the imaging range 61, disposed so as to surround the inspection position P, and respectively having reflection surfaces for reflecting images B1, B2, B3, and B4 of a side surface of the screw B positioned at the inspection position P so as to be captured by the camera; and an inspecting portion which determines the quality of the screw B on the basis of the images captured by the camera.SELECTED DRAWING: Figure 4 |
