<p>PURPOSE:To position a moving stand in the same position even when the stand is moved from any position side by moving either an intermediate stopper or an intermedi ate stopper abutting part, which constitute a moving stand positioning mechanism, in the moving direction of the moving stand and absorbing the deviation of the posi tion. CONSTITUTION:When moving stands 3 and 4 are moved from an L position side and one side part of an intermediate stopper abutting part 18 is abutted to one side part of an intermediate stopper 17 or when the moving stands 3 and 4 are moved from an S position side and the other side part of the intermediate stopper abutting part 18 is abutted on the other side of the intermediate stopper 17, both or either the inter mediate stopper abutting part 18 or the intermediate stopper 17 is moved and one side part of the intermediate stopper abutting part 18 and one side part of the interme diate stopper 17 is positioned in the same position as the abutted surface between the other side part of the intermediate stopper abutting surface 18 and the other side part of the intermediate stopper 17. Thus, even when the moving stands 3 and 4 are moved from either the L side or S side, the moving stands can be positioned and fixed in the completely same position.</p> |
