Abstract: The invention relates to a transporting device for flat objects, for instance printed circuit boards, comprising two endless carriers which are guided by two parallel extending guides, wherein the carriers are each provided with supports extending substantially horizontally in the direction toward the other carrier, wherein at least a part of the total number of supports is provided with at least one clamp fixing in substantially vertical direction flat objects resting on the supports. Preferably, the clamp is adapted to also exert a horizontal force on flat objects resting on the supports. This results in the flat objects also being fixed in the horizontal direction so that they cannot become detached in this direction either.
