Claims

[Scope of utility model registration request]

The planar shape is that a pair of fulcrum pins are integrally provided inside the left and right ends of the front lid in a three-letter shape, and the front lid is configured in upper and lower halves by the pair of fulcrum pins, and has an opening in the front. The front cover is rotatably attached to a provided cassette casing, and configured to be able to open and close the front opening of the cassette casing by rotating the front cover, and the front cover is connected to the outer periphery of at least one of the fulcrum pins. In a tape cassette configured such that its front cover is biased to close by a torsion coil spring provided inside one end, the side wall of the upper half of the cassette housing is provided with an L-shaped spring catch. A stop part is integrally provided between the spring stop part and the side wall of the upper half, and three
A spring locking groove is provided that is open toward the front and has a predetermined length in the front-rear direction, and the rear end of the torsion coil spring extends rearward in a horizontal direction and is inserted into the spring locking groove from above. A tape cassette characterized in that the tape cassette is configured to be locked in parallel with the side wall of the upper half.
