  • Patent number: 6801481
    Abstract: A connecting member connects a pair of holder plates toward the end of the holder plates at the recessed end in the direction in which the disk is inserted. By forming the holding member holding disks using three pieces, there is less deformation causes by high temperatures compared to integrally formed units. Also, since this connecting member only serves to connect the pair of holder plates, a thin rod-shaped connecting bar can be used. This allows the clearance between the disks held toward the back of the device and the rear panel to be minimized, thus contributing to a reduced depth dimension for the device.

  • Patent number: 6771782
    Abstract: The impact of disturbances on the amplifier parts for the L and R channels is reduced by attaching the cases for the L and R channels, spaced apart, to the case for the power supply. Only the relatively massive power supply is directly supported on a supporting surface. Independent support on the supporting surface of the signal processing parts of the L and R channel is omitted.

  • Patent number: 6295268
    Abstract: A cam member, having a cam groove on its outer surface, is slidably mounted on a rotating shaft to allow for movement of disk holders between a playback position and a stored position. In one embodiment, the cam groove is continuous about the cam member, making two complete rotations around the cam member. When a first disk holder is at the playback position, the cam groove engages the second disk holder at the stored position. When the second disk holder is selected to be played, rotation of the cam member causes the first disk holder to move to a stored position on an opposite end of the cam member while the second disk holder is in the playback position. The overall height required for such a disk holding device is constant, providing for a multiple disk playback device with minimal height requirements.
