<p><P>PROBLEM TO BE SOLVED: To provide a bar-shaped workpiece imaging apparatus capable of shortening measurement time and managing a bar-shaped workpiece with high precision, and a bar-shaped workpiece tip end concentric determination apparatus. <P>SOLUTION: A bar-shaped workpiece imaging apparatus includes a lens barrel 13 having beam splitters 42 and 43, spectrally separates an image light beam from an object lens 41 into three optical paths P1 to P3 and enlarges the image light beams P1 to P3 of the optical paths to capture the light beams with cameras 14, 15, and 16. By sliding the center positions of the optical axes of the beam splitters 42 and 43, the camera 14 connected to the lens barrel 13 is allowed to capture a tip-end processing part 21, the camera 15 is allowed to capture one part of the profiles of a main unit straight part 23, and the camera 16 is allowed to capture the another part of the profiles of the main unit straight part 23. By analyzing the image signals of these cameras 14, 15, and 16, the quality of a bar-shaped workpiece 10 is determined according to whether the position of the axis center of the tip-end processing part 21 is identical with the axis center of the main unit straight part 23. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
