Disk device

A disk device having a first turntable which supports a first disk, stored in a cartridge and having a top side and a bottom side, the first turntable transmitting a rotational force to the bottom side of the first disk, a second turntable which can be loaded onto and separated from the first turntable, which supports a second disk not stored in a cartridge and which transmits a rotational force to the second disk and, a spindle motor which rotates the first turntable, said disk device comprising:

• a retaining arm retaining the second turntable;
• a first shaft supporting the retaining arm to reciprocate vertically so that the second turntable is loaded onto or separated from the first turntable;
• a second shaft supporting the retaining arm to rotate and refuge in a planar direction;
• and
• an arm depressor depressing the retaining arm and refuging at least a section of the second turntable to a position below said bottom side of said first disk, after the retaining arm has been rotated in a planar direction and the second turntable has been refuged to a position which does not impede the first turntable.

A disk device having a first turntable which supports a first disk stored in a cartridge and which transmits a rotational force to the first disk, a second turntable which can be loaded onto and separated from the first turntable, which supports a second disk not stored in a cartridge and which transmits a rotational force to the second disk and, a spindle motor which rotates the first turntable, said disk device comprising:

• a retaining arm retaining the second turntable;
• a first shaft supporting the retaining arm to reciprocate vertically so that the second turntable is loaded onto or separated from the first turntable;
• a second shaft supporting the retaining arm to rotate and refuge in a planar direction;
• a clamp arm which retains a clamp, the clamp pressuring and holding said second disk on the second turntable;
• a third support shaft which is formed on an end of the clamp arm at a position which approximately corresponds to the second shaft of the retaining arm;
• and
• engaging sections provided on the retaining arm and the clamp arm, the engaging sections mutually engaging when the retaining arm is raised.

A disk device which loads and ejects a case-stored recording medium disk stored in a disk case and a non-case-stored recording medium disk not stored in a case and used as a single disk, the disks loaded onto and ejected from a turntable not at the same time, the disk device playing either the case-stored recording medium disk or the non-case-stored recording medium disk, said disk device comprising:

• a drive plate which displaces in a linear direction when a case-stored recording medium disk loading mechanism draws the case-stored recording medium disk to a fixed position in the device and loads the disk onto a turntable;
• a case-stored recording medium disk loading mechanism which draws a case-stored recording medium disk to a fixed position in the device and loads the disk onto a turntable due to the displacement of the drive plate;
• a non-case-stored recording medium disk loading mechanism which loads a non-case-stored recording medium disk, taken up to a fixed position in the device, onto a turntable and which supports a non-case-stored recording medium disk clamp and a non-case-stored recording medium disk adapter respectively to displace vertically and rotate;
• a cam mechanism which layers the non-case-stored recording medium disk clamp and the non-case-stored recording medium disk adapter together due to linear displacement of the drive plate;
• a depth displacement mechanism which, together with the displacement of the drive plate, displaces the non-case-stored recording medium disk clamp and the non-case-stored recording medium disk adapter layered together by the cam mechanism, in a direction into the device so as not to impede loading of a case-stored recording medium disk onto a turntable;
• and
• a refuge mechanism which displaces and refuges the non-case-stored recording medium disk clamp and the non-case-stored recording medium disk adapter, which are displaced into the device by the depth displacement mechanism, in a direction lower than the case-stored recording medium disk loaded onto a turntable.
