<p>PURPOSE:To eliminate the wasteful feed of a tape by driving two tapes for answering and receiving by independent pinch rollers. CONSTITUTION:Tapes T-1 and T-2 are driven by independent pinch rollers 5 and 6. To drive T-1 firstly, only pinch roller 5 is pushed against capstan 4 while pinch roller 6 is free from capstan 4. To drive T-2, pinch roller 6 is pushed against capstan 6 to drive only T-2 and pinch roller 5 is released from pressure contact with capstan 4. In this case, it is preferable that support fittings 17 and 18 for pinch rollers are supported by the same shaft 19.</p> |
