A conveyor apparatus includes a pusher piece 19 fixed to a conveying rod 18 adapted to reciprocate along a board conveyance path, and a switching mechanism adapted to switch the pushing piece, by turning the conveying rod a predetermined angle, between an engaged position where the pusher piece 19 engages with a rear end face of a board 7 and a retracted position where the pusher piece 19 does not interfere with the board 7. The switching mechanism includes a guide member 23 provided with a guide hole 24 adapted to guide a guide rod 22. The guide hole 24 is made up of first and second guide holes 25 and 26 configured to extend in parallel to each other in a conveyance direction and slanted coupling guide holes 27, 27 adapted to couple ends of the first and second guide holes 25 and 26. When the conveying rod 18 reciprocates, the guide rod 22 makes a round of the closed-loop guide hole 24. When the guide rod 22 is guided by the first guide hole 25, the pusher piece 19 is positioned at the engaged position. When the guide rod 22 moves from the first guide hole 25 to the second guide hole 26, the conveying rod 18 axially rotates a predetermined angle, thereby positioning the pusher piece 19 at the retracted position. |
