Claims

[Claims for Utility Model Registration] A reel brake that applies braking force by contacting a reel stand of a magnetic recording/reproducing device is biased by a spring in the direction of contacting the reel stand, and slides when the magnetic tape is in a high-speed running mode. In the reel stand braking device, the reel brake is moved away from the reel stand by a sliding slide, the reel stand braking device comprising: a cam gear that is rotated by a motor to form various modes; and a cam gear that rotates from a first rotation position to a second rotation position. a rotating member that slides the slide by;
a spring for rotationally biasing the rotating member to a first rotating position; a locking/disengaging member provided on the rotating member; a cam lever that engages with the engaging and disengaging member during the drive mode and rotates the rotating member to a second rotation position; A reel stand braking device comprising: a tripping member that displaces the engaging/disengaging member by rotation of a shaft to separate it from the cam lever.
