Claims

[Scope of utility model registration request]

The cassette housing has an opening on the front side, and the planar shape is ＼゛ 3 shape, and the left and right ends are rotated in the vertical direction to the left and right side walls of the cassette housing via a pair of first fulcrum pins. A front cover is configured to be movably pivoted to open and close the opening, and a second fulcrum pin is provided at the upper end of the front cover and is arranged behind the first fulcrum pin at one end of the front cover. It consists of a lock lever pivotally supported on one side wall of the cassette casing so as to be rotatable in the front and back direction, and a spring that biases the lock lever to rotate forward. The lock claw of the lock lever is engaged from below with a protrusion provided near the rear of the first fulcrum pin inside one end of the front cover, thereby locking the front cover in the closed state. In the tape cassette configured as shown in FIG. When the front cover is rotated from the open state to the closed position and the protrusion comes into contact with the lock claw from below, A tape cassette characterized in that a guide surface is provided on at least one of the lock pawl and the protrusion to allow the lock pawl to rotate rearward and escape.
