摘要： An elastic bearing member provided with a circular cross-section aperture through the center thereof suspends a cylindrical stylus shoe within the circular aperture. A star-shaped tapered recess is formed within the surface of the bearing member to the side opposite that of the stylus tip and extends inwardly approximately one-half the thickness of the elastic bearing. A wire coupled at one end to a fixed support rearwardly of the elastic bearing has the other end fixed to the shoe periphery at the point where the upper star point base merges with the circular aperture receiving the shoe to limit axial shifting of the stylus.

摘要： A tape recorder utilizing a tape cassette is disclosed which eliminates the tape slack between supply reel and take-up reel. When the tape cassette is placed in the play position, the supply reel is first rotated in the backward direction to remove the tape slack. Then the take-up reel is started to rotate by the stretched tape. A detecting device is provided to detect the rotation of the take-up reel in the backward direction. The detecting device triggers a control device which in turn switches the rotation of the take-up reel and permits pinch roller to engage with capstan to transfer the tape in the forward direction for ordinary performance.
