Abstract
PURPOSE:To prevent the tape from slacking between the capstan and reel stand, by interlocking the idler means to the displacement of the pinch roller. CONSTITUTION:When the operating member of constant speed drive is operated, the pinch roller arm 44 is turned by taking the shaft 40 as the center, and the magnetic head goes forward in interlocking with it. In this case, the gear arm 54 having the projection 54a in contact with the coupling shaft 88 implanted to the arm 44 is turned with the activated force of the tensile spring 100 and the constant speed drive gear gears with the reel stand gear 66. When the pinch roller arm 44 slightly turns from the moment of this gearing, the pinch roller 36 is pressed to the capstan 24 and the tape 132 is moved with a constant speed. At a constant speed, the coupling shaft 88 engaged with the projection 54a is released. At the stop operation, after the pinchroller 36 is detached from the capstan 24, and the constant speed drive gear 50 is detached from the reel stand 66.
