Abstract: The present invention provides a plate material carry-out device that can efficiently carry out a plurality of product plate materials cut from a raw plate material by a plate material processing machine, to a plate material carry-out section located outside the plate material processing machine. The plate material carry-out device includes tracks 11, 12 installed above and between a plate material processing machine 1 and a plate material carry-out section 3, a portable tray member 15 that is able to house a plurality of product plate materials W2, and two traveling members 13, 14 each having a holding member 20 capable of selectively holding the product plate materials W2 and the tray member 15; the traveling members 13, 14 are travelable along the track independently from each other. One of the traveling members, that is, the traveling member 13, causes the holding member 20 to hold the tray member 15 so that the tray member 15 stands by at a predetermined product reception position P2.
