Claims

[Scope of utility model registration request]

A center core is located approximately in the center of a flat space surrounded by an upper half and a lower half, and is chucked by a rotational drive shaft of a magnetic recording/reproducing device, and a transmission mechanism is connected to this center core via a timing belt. , a supply reel and a take-up reel arranged on both sides of the transmission mechanism so that rotational force is transmitted through the transmission mechanism, and a magnetic tape pulled out from the supply reel into the flat space. The transmission mechanism includes a first gear coupled to the timing belt, and a second gear meshed with the first gear. a gear; a third gear coaxial with the second gear and connected via a clutch; a fixed rack plate meshing with the third gear at a position remote from the first gear; It is comprised of a oscillation plate that supports the second and third gears so as to be able to swing relative to the spindle of the first gear, and when the center core rotates forward or reverse, the oscillation plate swings. The tape cassette is characterized in that the second gear rotates the take-up reel or the supply reel by the rotation of the tape cassette.
