PROBLEM TO BE SOLVED: To provide a speed variable conveyer device capable of safely transporting a conveyed object in a short time when a getting on/off part runs at a low speed and an intermediate part runs at a high speed. SOLUTION: The speed variable belt conveyer device has a plurality of conveying belts arranged longitudinally in series. The speed variable belt conveyer device comprises a conveying belt group where the plurality of conveying belts are arranged in parallel with a predetermined interval in the width direction of the belt and a plurality of rotating shafts for winding the conveying belt group. The rotating shafts have alternately axially arranged driving roller parts and driven roller parts, one end of each conveying belt in the longitudinal direction of the conveying belt group is wound on the driving roller part of the rotating shaft, and the other end is wound on the driven roller part of the other rotating shaft. By rotating each rotating shaft, each belt group runs at the same speed or a different speed. COPYRIGHT: (C)2004,JPO
