Abstract:
1. A vacuum processing apparatus for performing predetermined processing in a vacuum processing chamber on an elongated sheet base material transported through the vacuum processing chamber, the vacuum processing chamber comprising a single processing unit and an auxiliary vacuum chamber disposed in continuation with the vacuum processing chamber and having therein at least one of a feed roller and a take-up roller, the vacuum processing apparatus comprising: a pair of first roller units disposed on opposite sides across the processing unit in the vacuum processing chamber, the processing unit being located between the pair of first roller units, each of the first roller units having an axis and a plurality of rollers disposed along the axis and, each of the rollers being at an equal distance from adjacent rollers along the axis, the plurality of rollers of the first roller units being positionally shifted from one another in an axial direction in such a staggered manner as to allow the sheet base material to be helically wound around each of the rollers; and shifting means for shifting part of the sheet base material by a predetermined width toward the processing unit while a back surface of the sheet base material faces the processing unit, provided that a front surface is defined to be one surface of the sheet base material that faces the processing unit when traveling from each of the rollers on one side of the first roller unit to the other side of each of the rollers on the other side thereof.
