Magnetic tape cassette having automatic brake
First Claim
1. A magnetic tape cassette comprising:
- a hollow casing formed with an access opening therein;
tape transport means including a pair of reel hubs rotatably mounted within said casing in spaced-apart relation to each other for supporting a magnetic tape wound thereon, said tape transport means defining a tape run adjacent to said opening;
lid means;
mounting means mounting said lid means movably on said casing between a closed position wherein said lid means covers said opening, thereby affording protection to said tape, and an open position wherein said lid means uncovers said opening, thereby exposing said tape for cooperation with recording-reproducing apparatus; and
unitary brake means elongated in a direction parallel to said tape run and mounted within said casing movably between a braking position wherein said brake means locks said hubs against rotation and a releasing position wherein said brake means releases said hubs for rotation;
said lid means being engageable with said brake means and in moving from said closed position to said open position effecting linear movement of said brake means from said braking position to said releasing position and in moving from said open position to said closed position effecting linear movement of said brake means from said releasing position to said braking position.

Abstract
A magnetic tape cassette comprises a hollow casing formed with an access opening therein, tape guide columns, and a pair of reel hubs rotatably mounted within the casing in spaced-apart relation to each other for supporting a magnetic tape wound thereon and defining a tape run adjacent to the opening. A lid is mounted pivotally on the casing between a closed position wherein it covers the opening, thereby affording protection to the tape, and an open position wherein it uncovers the opening, thereby exposing the tape for cooperation with recording-reproducing apparatus. A brake member is mounted within the casing movably between a braking position wherein it locks the hubs against rotation and a releasing position wherein it releases the hubs for rotation. The lid is engageable with the brake member and in pivoting from the closed position to the open position effects movement of the brake member from the braking position to the releasing position and in moving from the open position to the closed position effects movement of the brake member from the releasing position to the braking position.
