Magnetic recording and reproducing apparatus

Abstract

Abstract A MAGNETIC RECORDING AND REPRODUCING APPARATUS WHEREIN A PINCH ROLLER MOUNTED ON A PINCH ROLLER ARM IS DISPOSED INTO OR OUT OF ROTATIONAL CONTACT WITH A CAPSTAN FOR TRANSPORTING A MAGNETIC TAPE UNWOUND FROM A REEL MOUNTED ON A REEL SHAFT, WITH SAID MAGNETIC TAPE BEING HELD BETWEEN SAID PINCH ROLLER AND SAID CAPSTAN, WHEREIN WHEN A PLUNGER IS ENERGIZED, SAID PINCH ROLLER IS BROUGHT INTO ROTATIONAL CONTACT WITH SAID CAPSTAN BY MEANS OF A SPRING INTERPOSED DIRECTLY OR INDIRECTLY BETWEEN AN OPERATING LEVER OF SAID PLUNGER AND SAID PINCH ROLLER ARM, WITH SAID MAGNETIC TAPE BEING HELD BETWEEN SAID PINCH ROLLER AND SAID CAPSTAN, WHEREIN AN IDLER WHICH IS ADAPTED TO BE DISPOSED IN AN OUT OF CONTACT WITH A DRIVING SOURCE IS BROUGHT INTO ROTATIONAL CONTACT WITH A REEL SHAFT WHEEL PROVIDED ON THE REEL SHAFT OR THE SHAFT IS CONNECTED TO THE DRIVING SOURCE THROUGH SAID IDLER AND ROTARY FRICTIONAL ENGAGEMENT MEANS, AND SAID IDLER AND SAID ROTARY FRICTIONAL ENGAGEMENT MEANS ARE UTILIZED AS MEANS FOR IMPARTING A BACK TENSION TO THE MAGNETIC TAPE AND MEANS FOR BRAKING SAID REEL SHAFT, AND WHEREIN THE IN-CONTACT OR OUT-OF-CONTACT RELATIONSHIP BETWEEN SAID PINCH ROLLER AND SAID CAPSTAN IS SECURED BY A LOCKING MECHANISM ASSOCIATED WITH THE OPERATING LEVER OF THE PLUNGER.
