PURPOSE:To adjust the height of a printed circuit board held between upper and lower guide rails by adjusting the height of the upper guide rails of a printed circuit board positioning device by air cylinders. CONSTITUTION:Upper guide rail parts 11 and 11 are moved to an upper first position by air cylinders 41 and 41, and a backup plate 25 is placed below the printed circuit board 10. The upper guide rail parts 11 and 11 are moved air cylinders 41 and 41 from the first position to the second position below the first position, and the board 10 is positioned. The first position can be changed by adjusting the strokes of the air cylinder 41 and 41. Therefore the rail 131 of the printed circuit board positioning part 104 can be moved to the height of the rail part 111 of the printed circuit board loading part 105 and the rail parts 121 of the printed circuit board unloading part 106. |
