Reel drive system of magnetic recording and reproducing apparatus

摘要

A magnetic recording and reproducing apparatus including a reel drive system having a first transmitting path for high-speed magnetic tape feed, and a second transmitting path for constant-speed magnetic tape feed. The first transmitting path includes a drive pulley for driving a pair of magnetic tape reels through oscillating idler means which is supported on a support shaft located on a bisector perpendicular to the center of the pair of magnetic tape reels to directly transmit the rotation of a reversible motor to the drive pulley. The second transmitting path transmits the rotation of the reversible motor through a slip mechanism to obtain a predetermined output torque. One of the two transmitting path is selected for each operation mode as switching of the operation modes is effected.
