Capstan drive type magnetic recording tape drive apparatus

A capstan drive type magnetic recording tape apparatus comprising:

• a chassis:
• a pair of reels on which is wound a magnetic recording tape;
• a first reel shaft rotatably mounted on said chassis for engagement with and rotation with one of said pair of reels;
• a second reel shaft rotatably mounted on said chassis for engagement with and rotation with the other of said pair of reels;
• a first slipping member rotatably mounted on said first reel shaft;
• a second slipping member rotatably mounted on said second reel shaft;
• a driving force transmitting means coupled to a drive means for selectively transmitting a driving force provided by said drive means to either said first slipping member or said second slipping member to cause said recording tape to travel in one or the other directions;
• a swinging member swingably mounted to said chassis for prohibiting rotation of said first slipping member by engaging said first slipping member when said magnetic recording tape is traveling in one direction and for prohibiting rotation of said second slipping member by engaging said second slipping member when said magnetic recording tape is traveling in the other direction;
• a first connecting means interposed between said first reel shaft and said first slipping member for rotatably connecting said first reel shaft with said first slipping member so as to transmit said driving force from said first slipping member to said first reel shaft, and for controlling the rotation of said first reel shaft relative to said first slipping member according to the difference between the rotational torque produced on said first reel shaft and the rotational torque produced on said first slipping member;
• and
• a second connecting means interposed between said second reel shaft and said second slipping member for rotatably connecting said second reel shaft and said second slipping member so as to transmit said driving force from said second slipping member to said second reel shaft, and for controlling the rotation of said second reel shaft relative to said second slipping member according to the difference between the rotational torque produced on said second reel shaft and the rotational torque produced on said second slipping
