Abstract

PURPOSE: To prevent the capstan of a tape recorder from vibrating by applying the capstan with a thrust-directional load by letting magnetic force operate on a flywheel formed together with the capstan in a body.
CONSTITUTION: Magnetic circuit 5 which applies capstan 1 with a load in the direction of bearing plate 4 is formed with magnets 6 anchored under flywheel 3 and iron plates 8 anchored on the top surface of the above-mentioned bearing plate 4 by forming magnetic gap (t) between iron plates and yokes 7 anchored on the external circumferences of corresponding magnets 6. As a result, since magnetic flux from magnet 6 constitutes magnetic circuit 5 in the direction of yokes 7, iron plates 8 and magnets 6, its magnetic force applies capstan 1 with a thrust-directional load to activate bearing plate 8. Capstan 1 is therefore prevented from vibrating in the thrust direction.
