<p>PURPOSE:To prevent the occurrence of the slackness of a magnetic tape at the time of the switching of an operation mode by providing a torque member which is driven by a reel stand of a supply side and stores energizing force to rotate the reel stand to a reverse direction. CONSTITUTION:A first and a second torque storage members 40, 41 are pivoted respectively to pins 35, 36 studded on a chassis 1, and are provided with gears to always engage with the gear parts 22b, 23b of the reel stand 22 or 23 turned into a feed side of the magnetic tape 6, and stores the energizing force to rotate the reel stand 22 or 23 to the reverse direction, and at the time of the switching of the mode, the reel stand 22 or 23 turned into a winding side is driven to a winding direction by this stored energizing force so as to wind the magnetic tape 6. Thus, the occurrence of the slackness can be prevented.</p> |
