Claims

[Scope of utility model registration request]

A center core is arranged approximately in the center of a flat space surrounded by an upper half and a lower half, and is tracked by a tracking table of a magnetic recording/reproducing device, and a center core is connected to the center core via a timing belt. a transmission mechanism; a supply reel and a take-up reel disposed 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 to the flat a plurality of tape guides for returning the tape to the take-up reel after circulating along the space, and a plurality of tape guides arranged in the center core in a vertical direction so as to engage with the first recess of the chucking table. a first drive pin that is movably biased; and a second recess into which a second drive pin that is movably biased in the vertical direction enters the tracking table;
A tape cassette characterized in that the inner wall of the second recess is a smooth surface.
