  • Compact sound record playing apparatus
    Patent number: 5247511
    Abstract: A casing of a sound record playing apparatus includes of an upper body (1B) and a lower body (1A), and a vibration plate (16) is formed by reducing a thickness of a part of the upper body. An inner surface of the vibration plate is in abutment with a pickup (13) to amplify the vibrations of the pickup. Thus, a conical speaker which has been used conventionary can be eliminated, and the thickness of the recording disk reproducing apparatus is reduced. Expansion member (6) includes cam surfaces (71b, 72b) which force the grooved recording disk (2) away from the pickup (13) when the expansion member (6) is rotated conversely.

  • Compact record player having downwardly extending notched rib and multiple selection levers
    Patent number: 5164927
    Abstract: A disk record sound reproducing apparatus includes a turntable having a cylindrical rib formed on the lower surface thereof and protruding downwardly therefrom. A plurality of selection levers, equal in number to a number of modulated grooves of a disk record, are pivotably disposed below the turntable, the levers being arranged radially with respect to the center of the turntable. Each selection lever has a drawn-down arm and a holding arm which are respectively engageable with a part of the turntable and the lower edge of the rib. When one of the selection levers is turned, the turntable is lowered by the draw-down arm which presses down the part of the turntable, and at the same time, the holding arm rides over the lower edge of the rib and enters the inside of the rib. Thus, the turntable together with the record disk is maintained at its lowered position, and the application of stylus force to the disk record is released.
