Abstract: A capstan motor for a magnetic recording and reproducing apparatus includes a stator having a coil disposed on outer peripheral direction thereof, and a rotor having a magnet to correspond to coil and rotated by an electromagnetic interaction between the coil and the magnet. A capstan shaft is rotated integrally with the rotor, is fixed on the rotor and installed so that one side of the capstan shaft is cohered with a pinch roller taking a tape therebetween to drive the tape with the pinch roller. The magnet has a predetermined shape and is provided to apply magnetic force of the magnet eccentrically for an electromagnetic force generated on the coil so that a predetermined thrust can be applied to the capstan shaft toward one direction between upper and lower directions of the shaft direction.

Abstract: A structure for pressing a cassette in a magnetic record and playback machine which includes a cassette holder having guide posts containing fixing slots on both lateral sides of the cassette holder, a driving arm having concave slots in which the guide posts are inserted, and an elastic supporting member surrounding the upper side and both lateral sides of the cassette holder. The upper part of the elastic supporting member has one or more folds which extend downward and both ends of the elastic supporting member are placed in the fixing slots of the guide posts, and both ends of the elastic supporting member are inserted into the concave slots of the driving arm along with the guide posts.
