Claims

[Scope of utility model registration request]

The front cover 7 that closes the front side of the main body case 1 is attached to the pivot 11.
It has a torsion coil spring 12 which is pivotally mounted around the front cover so as to be able to open and close, and which rotationally biases the front cover 7 to the closed position. The tip end 12d of the extending arm 12b is supported by a spring receiver 21 provided on the main body case 1 side, and the other extending arm 12C is supported by a spring receiver 20 provided on the front lid 7 side. A tape cartridge in which a tip end 12d of one of the extending arms 12b is bent in the same direction as the direction of the load applied to the coil spring 12 when the front cover 7 is rotated to open.
