Abstract
A tape cassette in which fixed guide pins (9), (10) are disposed at positions in which a wrapping angle at which a magnetic tape is wound around the fixed guide pins (9), (10) when the magnetic tape is transported is reduced that is the position at which the tape wrapping angle does not exceed 40.degree. wherein, a frictional force generated between the fixed guide pins (9), (10) and the magnetic tape (3) when the magnetic tape (3) is transported is reduced as compared with a conventional tape cassette, whereby a load on a motor for transporting the magnetic tape (3) is reduced, resulting in a life of a battery being extended.
