<p>PURPOSE:To enable the recording and reproducing of an image and voice by the reverse by making the structure of a tape running system about symmetric with respect to a cylinder drum and controlling a tape tension according to the tape running direction. CONSTITUTION:Two sets of tape guide means consisting of pinch rollers 10, 25 and tape guides 15, 60, 30, 61 with a drum 4 and capstan shaft 3 as the center are arranged about symmetrically in the vicinity of the cylinder drum 4 inclined in the prescribed direction by holding a rotary magnetic head and the capstan shaft 3. A pinch roller selecting plate 51 is made rotatable with the shaft 52 as the center and the regulating pin 57 fixed to the selective lever 55 selectively abuts the pinch roller to the capstan shaft 3 in a tape loading state. The tension pins 58, 59 interposed on a tape passage is interlocked with the selection of the pinch roller and by shifting to the mode to make the both at fixed position and to the mode to control the tape tension by releasing the fixture of one part side only the recording and reproducing of the reversal can be performed.</p> |
