Abstract

PURPOSE:To execute a tension control smoothly without being influenced by a running speed of a tape, by converting the ratio of frequencies corresponding to rotary angle speeds of a capstan and a reel, to voltage, also providing a hysteresis characteristic, and controlling the tension. CONSTITUTION:Disks 8, 11 to which magnets 9, 12 have been installed are provided on a capstan 2 and a reel 3, frequencies f1, f2 being in proportion to rotary angle speeds are generated, a digital signal being in proportion to f1/f2 is outputted through a counter 19, a CPU20, a memory 21, etc., it is converted to voltage, and reverse driving voltage is applied stepwise to a motor 6 in accordance with decrease of the wound diameter of the reel, by which tension is controlled. In this case, a circle E part where reverse driving voltage is varied suddenly is made to have hysteresis characteristic, so that voltage does not return to its original value unless a variation of the wound width of a tape becomes a prescribed extent or more, after the reverse driving voltage has been varied once, and a variation of tension due to vibration is prevented. In this way, tension is controlled smoothly without being influenced by a speed of a tape.
