<p>A reel braking mechanism for a magnetic tape recording and reproduction apparatus, which comprises first and second reel support bases (3L, 3R) adapted to support first and second reels (5L, 5R) rotatably, and is fixed so that the mechanism can be regulated with the first and second reel support bases (3L, 3R) synchronously along the respective paths between at least two positions, i.e. a first cassette position corresponding to a distance between the hubs of standard cassettes and a second cassette position corresponding to a distance between the hubs of compact cassettes. This reel braking mechanism is characterized in that it comprises braking levers (7L, 7R) supported pivotably on the reel support bases (3L, 3R), having first and second arms (7a, 7b) which are engageable with opposed reels, and movable between an engagement position in which the first arm (7a) engages and stops the opposed reel and a non-engagement position in which the first arm (7a) is disengaged from the opposed reel; and pressing members (10L, 10R, 10a, 11L, 11R; 10L, 10R, 10a, 11L, 11R, 24L, 24R; 10L, 10R, 11L, 11R, 30L, 30R) adapted to press the second arms (7b) irrespective of the positions of the reels so as to cause the braking levers (7L, 7R) to be moved to the engagement positions, thereby frictionally engaging the first arms (7a) with the opposed reels. <IMAGE></p> |
