PURPOSE:To attain smooth and sure magnetic running, by absorbing a magnetic tape contained in a tape driving section with air absorbing means, and providing a device with back tension. CONSTITUTION:A reel 1, a capstan 4, pinch rollers 5, 6 and a tape guide constituting the driving system of a magnetic tape 2 is provided on a square tape driving base 21, the base plate 21 is arranged on the same plane as a pin 16 and this plane is formed into a tapered plane higher upward in this paper. The tape driving base plate 21 is arranged at the right side of the tapered plane and the magnetic tape 2 is carried on the pin 16 being higher position than the plate 21. |
