。[Claims for Utility Model Registration] (1) A brake release pin that is supported so as to be able to move up and down between a raised position and a lowered position, and a brake release pin that stops the magnetic tape in the raised position when switched to the magnetic tape running mode. The cassette is equipped with a control means for controlling the drive to the lowered position when the mode is switched, and the cassette to be loaded has a flange part with unevenness on the outer circumferential surface integrally molded on the shaft part, and a magnetic tape is wound around the shaft part. a pair of reels, a pair of brake levers that stop rotation of the reels when engaged with the unevenness, a through hole into which the brake release pin is inserted, and the brake release pin is pressed at a raised position; In a magnetic recording and reproducing device comprising a brake release lever that releases engagement of the pair of brake levers, each of the pair of brake levers includes a first brake lever that restricts rotation of the reel in one direction, and a second brake lever that restricts rotation of the reel in one direction. A brake mechanism characterized by comprising a second brake lever that restricts rotation in the direction. (2) A pair of the brake release pin and the brake release lever are provided corresponding to each of the pair of brake levers, and the control means includes:
The brake mechanism according to claim 1, wherein the brake mechanism is configured to drive and control each of the pair of brake release pins independently.
