ABSTRACT:
A tape tension control apparatus is applied to a tape winding apparatus for winding a magnetic tape into a tape cassette. In this apparatus, a tampered slot is formed on the back of a vacuum chamber, and the change of the tape position when the magnetic tape is wound into the tape cassette is detected as a change of pressure resulting from a change of the effective width of the slit. Therefore, a constant tape tension can be maintained during the winding process.
