A printed-board conveying apparatus including a first belt conveyor including first stationary and movable guide rails and two first belts which are circulated while being guided by the two first guide rails, respectively, and which support opposite end portions of a first printed board, respectively, and cooperate with each other to convey the first printed board, and a second belt conveyor which is arranged in parallel with the first belt conveyor and which includes second stationary and movable guide rails and two second belts which are circulated while being guided by the two second guide rails, respectively, and which support opposite end portions of a second printed board, respectively, and cooperate with each other to convey the second printed board. The first and second stationary and movable guide rails extend parallel to one another such that the first and second stationary guide rails are provided outside the first and second movable guide rails, respectively. Each of the first and second movable guide rails is movable toward, and away from, a corresponding one of the first and second stationary guide rails, so as to change a width of a corresponding one of the first and second belt conveyors. One of the two movable guide rails is movable, over a middle position between the two stationary guide rails, toward one of the two stationary guide rails that does not correspond to the one movable guide rail, so as to increase a width of one of the two belt conveyors that corresponds to the one movable guide rail.
