ープカセット。The cassette casing consists of an upper and lower halves with an opening on the front, and the planar shape is an S-shaped three-shape, and the left and right ends of the cassette casing are connected to the left and right sides of the cassette casing through a pair of first fulcrum pins. a front cover configured to be rotatably supported in the vertical direction on both side walls so as to be able to open and close the opening; A lock lever is pivotally connected to one side wall of the cassette casing via a second fulcrum pin so as to be rotatable in the front and back direction, and a lock lever is wrapped around the outer periphery of the first fulcrum pin to move the lock lever forward. The lock lever is locked by a projection integrally provided at a position near the rear of the first fulcrum pin inside one end of the front lid when the front lid is closed. In the tape cassette configured to lock the front lid in the closed state by engaging the claws from below, the first fulcrum pin and the second fulcrum pin are connected to the side wall of the upper half at an intermediate position S. A horizontal portion and an L-shaped protrusion having a vertical portion at the lower front end of the horizontal portion are integrally provided, and the vertical portion of the L-shaped protrusion has a taper diagonally upward and outward from the side wall of the upper half to the horizontal portion. When the lock lever is rotated forward from the locking position of the front cover, the upper end of the lock lever is placed above the second fulcrum pin, and the rear end of the horizontal part of the shaped protrusion The lock lever is brought into contact with the lower side surface to restrict the forward rotation of the lock lever, and during assembly, the rear end of the torsion coil spring wound around the outer circumference of the first fulcrum pin is pressed against the above-mentioned shaped protrusion. A tape cassette characterized in that the tape cassette is configured to be guided by the tapered surface of the tape cassette and temporarily fixed by being twisted onto the horizontal part of the L-shaped protrusion.
