Claims

[Scope of utility model registration request]

In a magnetic tape cassette that incorporates a pair of flangeless type hubs loaded with magnetic tape and has an opening that allows the magnetic tape to be pulled out to the front of the cassette, the magnetic tape is pivoted near the front of the cassette on the left and right outer walls of the cassette. a first guard panel shaped like a horizontal cross section, which is capable of opening the cassette up and down and is biased in the closing direction to close the front side of the opening; a lid portion and a slide body that close the lower side of the opening; a plate-shaped second guard panel that is biased toward the front of the cassette and slides in the front-back direction of the cassette along the inner surface of the bottom of the cassette; a storage recess that slidably accommodates the second guard panel; and a pair of reel shafts. The cassette case is provided with an insertion hole and has holes formed through the outer wall and the inner wall parallel to the outer wall, respectively, which constitute the tape outlet at both left and right ends of the opening. The optical signal path of the optical sensor is connected to the hole,
A magnetic tape cassette, characterized in that the magnetic tape cassette is configured to pass through the central hollow portion of the tape outlet and the opening.
