Abstract
A cassette includes a slack limiter which engages tape extending from reels within the cassette and prevents the tape from unwinding from the reels and developing slack or looseness. In one embodiment, the slack limiter is formed from a thin, flexible, resilient strip of material which includes a mounting portion formed by folding the strip to produce a compression member extending at an acute angle to the slack limiter. In a second embodiment, the slack limiter includes two oppositely extending strips and a mounting portion formed by two folds and an interconnecting compression member. In either embodiment, the mounting portion of the slack limiter is retained in the housing by a receptacle which compressively engages and bows the compression member.
