<p>PURPOSE:To use a tension post as the tension detecting mechanism of a tape control and to execute the tension control with a good performance even to the cassette with a different size by providing a tape guide at the position connected to the line to link the tension post and the tape guiding pin of a small cassette or at the near position. CONSTITUTION:Two cassettes 1 and 2 with the different position of tape guiding pins 6 and 7 can be used, the driving force of a winding reel stand 4 is controlled based upon the signal to come out from the device to detect the rotating quantity of a rotating arm 22 due to the tension of the tape loaded to a tension post 20, and a tape guide 21 is provided at the position connected to the line to link a smaller tape guiding pin 7 of the cassettes 1 and 2 from the tension post 20 or at the near position. Thus, the winding angle of the tension post 20 comes to be approximately constant regardless of the size of the cassettes 1 and 2.</p> |
