PURPOSE:To enable the positioning of a printed circuit board regardless of the board thickness of the printed circuit board in the case of conveying the printed circuit board by endless belts. CONSTITUTION:A printed circuit board 1 is conveyed by endless belts 2A, 2B stretched over plural pulleys 3A, 3B. A group of rollers 5 guide the endless belts 2A, 2B in the form of moving the printed circuit board 1 horizontally. When the end part of the printed circuit board 1 is stopped coming in contact with a stopper 8, a push-up means 5 pushes up the printed circuit board 1, and the pushed-up printed circuit board 1 is held in the horizontal state by holding plates 6A, 6B. Positioning pins 7 then enter the positioning holes 1A of the printed circuit board 1 to position the printed circuit board 1. |
