<p>PURPOSE:To prevent noise band without affecting the running and to operate with a simple driving mechanism, by operating a shifted pole and a tilted post at a tape departure side of a head drum and a guide post at a tape approach side respectively at high speed reproduction. CONSTITUTION:A review slide 15 is pulled right, a tilted post 9c of a review post arm gives a required inclination to a tape 1, the shift pole 2 pushes up a lower ridge of a tape 1 upward to shift a tape running path, and the guide post 12c of a review guide arm 12 presses down the tape 1 downward slightly to give a suitable tension in the review mode. The tape 1 is wound on the tilted guide pole 5 with this tension, and wound on the head drum 4 and passes through the tilted guide pole 3 and is pushed upward with the pole 2. The height of running of the tape 1 is regulated to the same height as the normal reproduction so that the pushing-up does not exert effect on the running of the tape 1.</p> |
