<p>PURPOSE:To automatically eliminate the slackness of a magnetic tape when it occurs in the tape inside only by loading a tape cassette by providing a cassette detecting switch and a motor switch for tape slackness elimination. CONSTITUTION:When the slackness occurs on the tape in the cassette at the time of loading the tape cassette 5, a tape driving motor is connected to a power source via the cassette detecting switch 6 and the motor switch 8 for tape slackness elimination, and the torque of the tape driving motor 9 is transmitted to a reel receiver 2a on one side via a rotation transmission means 25 for tape slackness elimination, and a reel receiver 2b on the other side is prohibited to rotate with a brake means 16. When the elimination of the slackness of the tape is detected with a tape slackness elimination detecting means 37, a rotation transmission path by the rotation transmission means 25 for tape slackness elimination is cut off, and also, a brake by the brake means 16 is released, and also, the motor switch 8 for tape slackness elimination is switched, then, the tape driving motor 9 is cut off from the power source, then, it is stopped.</p> |
