Abstract

PURPOSE:To simplify the construction, by providing a pair of tape tension detection mechanism at the upper and lower sides of the stream of tape run to the capstan and respectively controlling a pair of reel motor running speed based on the detection of the detection mechanism. CONSTITUTION:A pair of tape reels 2, 3 a pair of reel motors 6, 7 turning and driving the reels 2, 3, and capstan 9 on which the tape 1 run between the reels 2 and 3 is wound with a given winding angle, are provided. Further, the capstan motor 10 driving the capatan 9 with an arbitrary speed, a pair of tape tension detecting mechanisms 13, 14 located at the upper and lower sides of run of tape 1 to the capstan 9, and the rotating speed of a pair of reel motors based on the detection of the detecting mechanisms 13, 14, are respectively controlled with the reel motor control circuit so that the tape tension between the upper and lower stream sides of the tape 1 to the capstan 9 can almost be kept constant.
