A straight narrow groove is formed in each of the turn storage jig a and the orienter jig c. Then, two gauges g to be fitted into these linear narrow grooves are prepared. IC turn storage 300
When the vertical axis of the orienter 114 and the vertical axis of the orienter 114 are aligned and positioned therebetween, the linear narrow groove of the turn storage jig a and the linear narrow groove of the orienter jig c are aligned, and When the gauge g is fitted, it is confirmed that there is no step between the two gauges g, and the vertical axis of the IC turn storage 300 and the vertical axis of the orienter 114 are accurately aligned.

However, while the IC turn storage 300 has a degree of freedom in the horizontal direction, the orienter 114
Since it has a degree of freedom in a direction orthogonal to the drive direction of the turn storage 300 and rotates in this direction, accurate confirmation could not be made based on the above-described confirmation. For example, even if it can be confirmed that there is no step between the two gauges g, it is simply confirmed that there is no step only at the tip of the two gauges g. It cannot be said that it could be confirmed.

The present invention provides a jig for adjusting the position of a test handler of an IC tester which has solved the above-mentioned problems.
