Abstract
A shifting device for fixing and conveying a tape comprises a first head having a first surface to contact with a top of the tape, and a second head having a second surface to contact with a bottom of the tape. The first surface has a plurality of first strip-shaped projections thereon, and the second surface has a plurality of second strip-shaped projections thereon, such that the top surface of first striped-shaped projection is parallel to the first surface and the top surface of the second strip-shaped projection is parallel to the second surface. When the first head and the second head come into contact with the tape, the first strip-shaped projection is perpendicular to the second strip-shaped projection such that pressed regions of the tape which are pressed by both the first head and the second head are distributed in an array.
