PROBLEM TO BE SOLVED: To secure a wide belt carrier face by providing a curve guide device which travels a fan-shaped conveyer belt having an edge guide member into a fan shape with a plurality of rollers which are vertically raised/lowered and freely rotated and whose outer circumferential edge are fitted into a groove in the edge guide member of the belt. SOLUTION: In a device which travelingly guides a conveyer belt 1 into a fan shape by holding the edge guide member between upper and rear sides, 2 by a curved guide device 14, the edge guide member 2 having a groove 20 in its top is attached to the whole circumference in the top face of the outer circumferential part 13 of the conveyer belt 1 and this edge guide member 2 is so provided as to bring its bottom face in contact with the surface of the conveyer belt 1. The curved guide device 14 is so attached to a frame 5 arranged along the outer circumference 13 as to rotate presser rollers 4 whose outer circumferential edges 21 can be fitted to the groove 20 and approach to/separate from the groove 20. The presser roller 4 is so supported as to freely raise/lower in the direction (x) perpendicular to the frame 5 and the rear face attaching the edge guide member 2 is supported by a support roller 6.
