ABSTRACT:
A brake mechanism in a magnetic tape recording and reproducing machine in which a magnetic tape is transported from one reel to the other reel comprising brake drums corresponding to two reels, brake shoes, means for securing the brake shoes and means for pressing the brake shoes to respective brake drums. Two micro-switches are provided for detecting the displacement of the respective means for securing the brake shoes in the direction of the rotation of the respective brake drums caused by the friction between the brake shoes and the brake drums in the operation of the brake mechanism.
The two micro-switches are used for controlling a circuit giving D.C. current to stator windings of two electric motors for driving respective reels so that the rotors of both motors may be subjected to electromagnetical braking. The two micro-switches are also used for prohibiting the machine from starting until the tape transportation is perfectly stopped after operation of the brake mechanism.
