PURPOSE:To provide sure transport of printed circuit boards by using a reference hole in each printed circuit board, by furnishing a guide pin to fit in this hole and a push bracket to push the trailing edge of the circuit board being exhausted, and thereby transporting printed circuit boards well separated. CONSTITUTION:When a printed circuit board 4 sent by a belt on a rail 8 is stopped upon being located by a stopper 23, rails 8, 9 of a circuit board feed device 101 and an exhaust device 102 are sunk through the action of a cylinder. Then a guide pin 24 is sunk by a vertical operating cylinders 27 to set it in a reference hole 4a in the printed circuit board 4, and at the same time the above- mentioned stopper 23 is released. A lever pin 6 is sunk at the same time interlocked with the rail 9. Then the circuit board 4 is transported to the position of lever pin 6 in the positioner part 100 by the above-mentioned guide pin 24 through the action of cylinder 26, and at the same time a push bracket 25 exhausts a circuit board 5 to the rail 9, and thereafter the cylinders 27, 26 shall make return action. |
