<p>PURPOSE: To correct the positional discrepancy of each glass substrate, which is mounted on each shelf of a cessette, all at once for alignment and to place the glass substrate, within a prescribed range, on an inspection table. CONSTITUTION: Two, for example, sets of freely turnable rollers 61a, 61b, which are installed in both sides of a cassette 2, are turned by a turning mechanism 62, so that the rollers 61a, 61b are brought in contact with both sides of glass board 1. The glass baord 1 is elevated by an ascending/descending mechanism 63, so that both ends of each glass board 1, which are attached to each shelf 23, are raised and at the same time pushed/pressed in the horizontal direction, during which time the glass board 1 is aligned in the lateral direction. After this, the rollers 61a, 61b are turned, so that the rollers 61a, 61b are apart from the both sides of the glass substrate 1. Then, the glass board 1 is descended to be mounted again on the shelf 23.</p> |
