ABSTRACT:
A braking apparatus for the cover of a chamber in a recording and/or reproducing apparatus includes a stationary plate, a shaft connected to the plate and extending in a direction perpendicular therefrom, an actuating disc arranged on the shaft for rotation in a clockwise and a counterclockwise direction, a damping disc rotatably arranged on the shaft between the plate and the actuating disc, means for urging the discs simultaneously toward the plate and a silicone grease provided between the plate and the damping disc. The grease contacts both the plate and the damping disc. The braking apparatus further includes means for uniting the discs and providing simultaneous unidirectional damped rotation by the discs only when the actuating disc is rotated in the counterclockwise direction.
