Abstract
A brake driving apparatus of a tape recorder includes a reel braking part for driving brakes with a force transferred from a capstan motor to stop the rotation of reels, and a reel releasing part for releasing the brake of the reels by being slidably driven and down with a force transmitted from a loading motor.
Claims27
A brake driving apparatus of a tape recorder, said apparatus comprising:
- reel braking means for braking reel tables with a force transferred from capstan motor means, said capstan motor means for transporting a tape by driving said reel tables, said reel braking means comprising:
- an arm having a slot and being rotated on a fixed axis by a driving force transmitted from said capstan motor means,
- brakes for engaging said reel tables and being rotated on stationary axes, said brakes being biased by a spring, and
- a pin connecting said brakes to each other and for being mounted into and dismounted from said slot of said arm;
- and
- reel releasing means for releasing said brakes to enable rotation of said reel tables, said reel releasing means being slidably driven by a loading motor.
