Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To facilitate the traveling speed control covering the range from low speed to high speed when the high speed traveling of FF(fast-feeding)/REW (rewinding), etc., is executed, and also to execute the stable low speed traveling. SOLUTION: In the case the device is provided with a reel motor FG control part 2 and a tape speed control part 3, when the FF/REW is performed, the low speed traveling control is executed at first by the control of the reel motor FG control part 2 so that the reel motor 1 is rotated at a prescribed rotating period. Next, the acceleration is started and the high speed running control is executed by the control of the tape speed control part 3 so that the tape speed becomes a prescribed speed. When the tape comes close to the tape end, the speed reduction is started, and by control of the reel motor FG control part 2, the low speed traveling control is executed again, and the tape is stopped after that.
