Abstract
Tape drive apparatus having a drive roller 1 and pinch roller 2 including a idler roller 3 around which tape 4 passes. The pinch roller 2 which is rotatable about two normal axes (A2 and A4), is resiliently urged against the drive roller 1 and the idler roller 3, the two rollers being spaced apart from each other. This apparatus is particularly useful for magnetic tape cassettes, the pinch roller 2 being formed as either part of the cassette or as part of a tape recorder/player for using a cassette.
