<p>PURPOSE:To secure the tape lead-out action through the tape winding substance at the side where the tape is easily led out by providing the motors independently to drive the reels of the supply side and the take-up side each and then giving nearly the same take-up torque to each motor in the mode of tape lead-out action. CONSTITUTION:Almost the equal voltage is applied to a pair of reel motors 6 and 7, and thus reel disk assemblies 9 and 11 are turned in nearly the same torque and in the cunterclockwise direction, i.e., in the tape take-up direction. Thus tape 66 is taken out of the cassette in the state under which the back tension affecting tape 66 is minimized automatically. The tape lead-out speed out of the cassette is nearly constant at each time point in the course of the tape lead-out action. As a result, the excessive back tension is never applied to tape 66 being led out, thus ensuring the steady tape lead-out action.</p> |
