Title:
DISC DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/083539
Kind Code:
A1
Abstract:
It is possible to suppress contact between disc holding means and a disc by using a simple configuration. A clamper (3) is arranged on the disc device and holds the disc during rotation of the disc. That is, the clamper (3) rotates together with the disc. Moreover, when the disc device is arranged so that the center axis (Zc) of the clamper (3) orthogonally intersects the action direction (G) of the gravity and the clamper (3) does not hold a disc, the inner surface of a support hole (2h) of the clamper holder (2s) is engaged with an external circumference of the clamper (3) so as to support the clamper (3). On the inner surface of the support hole (2h), two disc holding means (CA, CB) are arranged at the portion above the lowermost points (3L) of the clamper (3) with respect to the action direction (G) of the gravity. The clamper (3) is supported on the clamper holder (2s) by the disc holding means support unit (CA, CB).
