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 are 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 is placed in the flat space. a plurality of tape guides for returning the supply reel or the take-up reel to the take-up reel after circulating along the center core; A tape cassette, characterized in that, when the center core is stationary, the center core is arranged to slightly mesh with a gear that transmits rotational force to the supply reel and the take-up reel.
