These are fast-forwarding levers that can be rotated independently of each other around the rotation center of the levers, and both are connected by a relatively weak spring 30 so that they can rotate together. One end of the fast-forwarding lever 19a is configured to abut and engage with an engaging pin 7 provided on the L-shaped lever 5, and the other fast-forwarding lever 19b abuts and engages with a protrusion 20a provided on the fast-forwarding lever 20.

Apply a relatively weak rotational force in the counterclockwise direction.
この回動力はバンドアーム５の係合ピン１７を
通じて、バンドブレーキ３に比較的弱い引つ張り

A rotatable band arm, a rotatable tension arm having a tension post implanted at one end, one end of which is engaged and fixed to the band arm, and the other end of which is engaged and fixed to the tension arm. a band brake that applies a braking force to the reel stand; a first spring that elastically biases the tension arm to rotate in a first direction in which the braking force of the band brake increases; and a first spring that is coaxial with the tension arm. a lever that is rotatably provided in the tension arm and has an abutting portion that abuts one end of the tension arm; and the abutting portion of the lever abuts the one end of the tension arm so that the tension arm a second spring that applies an elastic force to the lever so that it can rotate in a second direction opposite to the first direction; and a direction that pushes the band arm at one end during recording and playback to increase the braking force by the band brake. At the same time, the band arm is rotated, and the lever is rotated against the second spring by pushing the lever at the other end, thereby separating the abutment part and the tension arm, and causing the first spring to move. A normal feed intervening lever that urges the tension arm in a first direction, a fast feed intervening lever that can come into contact with the band arm at one end, and a braking force by the band brake that applies the braking force of the band arm to the band arm via the fast feed intervening lever during fast forwarding. A third spring is provided to bias the rotation in the increasing direction, and at the time of rapid forwarding,
A stopper is provided for regulating the amount by which the lever is rotated by a second spring when the engagement between the normal feed intervening lever and the lever is disengaged, and the rotation of the tension arm in the first direction is restricted. A back tension device characterized by comprising:
