摘要
A reel drive system has a transmitting path for high speed magnetic tape feed, and a second transmitting path for constantspeed mangnetic tape feed. The first path includes a drive pulley for driving a pair of magnetic tape reels through an oscillating idler. The idler is supported on a support shaft located on a bisector perpendicular to the center of the pair of magnetic tape reels. It directly transmits the rotation of a reversible motor to the drive pully. The second path transmits the rotation of the reversible motor through a slip mechanism to obtain a predetermined output torque.
