SOLUTION: With the device, auxiliary rollers 5 which face the outer peripheral surfaceses 4a of plural conveying rollers 4 arranged on opposie sides in a double line in a horizontal plane, and which rotate at angle α outward deviated from the conveying direction 12, following the rotation of the conveying rollers 4, are provided. Thus, two, parallel sides of a printed-wiring board 1 are held between the auxiliary rollers 5 and the conveying rollers 4 by the dead loads of the auxiliary rollers 5, and the printed wiring board 1 is conveyed while it is tensed outward by the diagonal, following rotation of the auxiliary rollers 5. |
