ンシヨンアーム移動機構。[Claims for Utility Model Registration] It has a tension servo mechanism that swings the tension arm as the tape tension changes and controls the braking force of the supply reel stand to keep the tape tension constant. , in the tension arm moving mechanism in which the tension arm is forcibly moved in the direction of loosening the magnetic tape in the reverse mode to eliminate the braking force on the supply side reel stand, the mode transition from the play mode to the reverse mode. During the transition period, the magnetic tape meshes with an idler gear connected to the supply reel stand to forcibly rotate the supply reel stand in the tape winding direction while resisting the braking force of the tension servo mechanism. a winding mechanism; a rotatable tension lever linked to the magnetic tape winding mechanism and rotated according to the amount of rotation of the supply reel base; A tension arm moving mechanism for a magnetic recording/reproducing device, comprising a locking part provided on the tension arm to be pushed by a tension lever.
