。As mentioned above, is the present invention a cassette positioning ball? Free rotation of a pair of reels inside the cassette corresponding to the positioning holes to be inserted? A brake member for blocking is provided in the cassette. Since the positioning ball of the cassette is used so that it is activated via the positioning ball to prevent and release the rotation of the reel only when the cassette is attached to the playing condition, the overall structure can be simplified, and the cassette can be used to prevent the cassette from being in a bad playing condition. You can keep the brake on the reel until you install it! ! t+VTR reel shaft brake function 10
By using 0% of the tape, it prevents the tape from loosening, completely preventing various problems caused by the tape, and also prevents the brake tf@ from being accidentally released with the fingertips when handling the cassette.
