<p>PURPOSE:To perform stable drive force, by specifying the construction of drive wheel, driven wheel and idler. CONSTITUTION:The pulleys 20, 21 at the capstans 11, 12 being drive wheel, and the pulleys 28, 29 at reel stands 16, 17 being driven wheel are constituted with rubber pulley having elasticity, and the two idlers 23, 24 linking the drive and driven wheels are taken as gear. Thus, the idlers 23 and 24 are pressed to the pinch roller 13 or 14 and the capstan 11 or 12 with the turning of the idler hold plate 30, and the drive force of the capstan 18 or 19 is delivered to the reel stand 16 or 17. When the magnetic tape 15 is wound forward or reverse, vibration and noise are absorbed with the ruber of pulleys 20, 21, 28, 29 to achieve the objective.</p> |
