Claims

[Scope of Claim for Utility Model Registration] A magnetic tape suspended between a supply reel and a take-up reel is wound around a drum equipped with a magnetic head, and the magnetic tape is mounted on the tip of a swingably supported tension arm. The tension pole is urged by a spring to contact the magnetic tape, and a brake band connected to the tension arm is wrapped around the supply reel, and this brake band tightens the supply reel by the swing of the tension arm. In a tape tension adjustment device for adjusting the tension of a magnetic tape, a gear is fixed to the tension arm, and a transformer arm to which a gear meshing with the gear is fixed is swingably supported. A tape tension adjustment device, characterized in that the brake band is connected to an arm.
