PURPOSE:To improve the reproducibility of positioning by elevatably providing a correcting block with a correcting arm making correction from four directions, back-and-forth and left-and-right, of a stopper on a positioning block with the stopper. CONSTITUTION:A frame 26 is conveyed by a conveyor belt 20. After the frame 26 is stopped by a protrudable stopper 22, a positioning block 23 is position- corrected by a position correcting block 24. Since the position correcting block 24 is provided with back-and-forth correcting arms 25 facing the stopper and left-and-right correcting arms 27 so that their facing distance can be changed respectively, the frame 26 can be positioned correctly from four directions. |
