Claims

[Claims for Utility Model Registration] A tape cassette having a locking member for stopping reel rotation that engages and disconnects from a tape reel on which magnetic tape is wound is attached, and the tape is moved from the supply reel side to the take-up reel side. Magnetic recording while running,
In a magnetic recording and reproducing apparatus that performs reproduction, a swinging motion for displacing a locking member provided in the tape cassette for stopping rotation of the reel between a first position in which it locks to the tape reel and a second position in which it is separated from the tape reel. When the member and the tape cassette are installed in the device,
a release member disposed in the cassette at a position facing the swinging member; and after the tape cassette is installed, the release member is operated so that the swinging member displaces the locking member to a second position. What is claimed is: 1. A magnetic recording and reproducing device comprising: a displacement means for causing the displacement;
