It is carried by being picked up and down by the conveying roller 2 to apply a pressing force to the printed wiring board material A. d In contrast, the conveying rollers 2 'of the conveying mechanism 1 are each formed into a straight cylindrical shape. Due to the printed wiring board material A being conveyed by these a'b, c, and d ', for example, after passing through the front end portion, the outer peripheral surface of the conveying roller 2 that is driven by rotation, many closely abutting and winding accidents occur. It is indicated by a solid line as shown in the figure. Although it shows an example of being wound around the outer peripheral surface of the lower conveying roller 2, as shown by a dotted line, it is often wound around the outer peripheral surface of the upper conveying roller 2. As such, when printing wiring When the base sheet A is wound around the conveying roller 2, its smooth conveyance is impeded and uncertainty will occur, resulting in manufacturing defects. That is, 1 due to winding, not only the printed wiring base sheet A will be bent and folded. , Or drop, or damage, and surface treatment such as chemical solution treatment or cleaning treatment can not be performed as required. The occurrence of such a situation is that, as described above, for a printed wiring board that has been miniaturized, the circuit has become denser, miniaturized, and highly precise, lowering its reliability has not only become a fatal defect, but the R yield has also deteriorated. And productivity issues.
