BRAKE MECHANISM FOR REEL TURNTABLE OF MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PURPOSE:To make it possible to easily and rapidly load and unload a magnetic tape without damaging this magnetic tape. CONSTITUTION:This brake mechanism is provided with a pendulum gear 20 which oscillates and drives one reel turntable by meshing therewith between a feed reel turntable 4 freely rotatably supported on a moving chassis 2B and a takeup reel turntable. A brake lever 30 which applies the brake to the take-up reel turntable side at the time of loading the magnetic tape around a rotary head drum provided at a stationary chassis 2A is freely rotatably and slidably supported with respect to the moving chassis 2B. This brake lever 30 is provided with a rack part 30d which meshes and parts with and from the tooth part 45c of a limiter gear 45 of the feed reel turntable 4. A stopper arm 33 which holds the meshing state of the rack part 30d of the brake lever 30 and the tooth part 40c of the feed reel turntable 4 are freely rotatably supported on the moving chassis 2B.
