PROBLEM TO BE SOLVED: To provide a base material conveyor width changing method and a base material conveyor capable of at least one of an accurate change and an inexpensive change in a conveyor width. SOLUTION: A printed wiring board 24 is carried by a feeder 164 while being guided by a fixed guide rail 110 and a movable guide rail 112. Reference marks 220 and 222 are respectively arranged on the guide rails 110 and 112. When changing the conveyor width, the movable guide rail 112 is moved by an interval changing device 214, and is made to follow while imaging the reference mark 222 by a CCD camera for imaging the reference mark of the printed wiring board 24. The CCD camera is moved to a target position in a state of approaching the target position to image the reference mark 222, and is stopped by detecting the arrival of the movable guide rail 112 at the target position. The CCD camera may be moved to the target position before the movable guide rail 112 from the beginning. The CCD camera may be made to follow the movable guide rail 112.
