JIG FOR MEASURING SIZE OF WORK PIECE

摘要

A jig (20) provided in a device for measuring the sizes of a work piece (10) on the basis of images obtained by capturing the images of the work piece (10) using a camera (K). The jig (20) is equipped with a chuck mechanism (50) for retaining the work piece (10), a first rotation driving mechanism (80) which rotates the chuck mechanism (50) around a predetermined first rotary shaft (A), a first base (30) which retains the first rotation driving mechanism (80), a second rotation driving mechanism (40) which rotates the first base (30) around a second rotary shaft (B) orthogonal to the first rotary shaft (A), and a second base (21) which retains the second rotation driving mechanism (40). In the first base (30), an opening through which the work piece (10) retained by the chuck mechanism (50) can be seen from the rear side of the first base (30) is formed in an area surrounding the first rotary shaft (A).+
