Abstract
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.
