<p>PURPOSE:To prevent the occurrence of tape damages by absorbing an increase of a clutch torque with an added rotary clutch even if the sliding speed of a clutch in a reel stand structure and preventing an increase of a torque for winding a tape. CONSTITUTION:At a high speed regenerating mode, a adder rotary structure 10 is moved to the arrow direction. When a rotary gear 11 is engaged with a reel stand gear 5, the rotary gear 11 rotates through a frictional clutch coupling plate 14, connecting with a clutch plate 15 under pressure. At the high speed regenerating mode, a clutch torque increases with the increase of the sliding speed between a clutch gear 2 and the reel stand 5. In addition, the fricted torque increases with the increase of the sliding speed between a rotary gear 11 and a frictional plate 15 in an added rotary structure 10 engaged with a reel stand structure 9. Consequently, the increase of the clutch torque of the reel stand structure 9 is absorbed by a clutch of an added rotary structure 10 to prevent the occurrence of tape damages.</p> |
