Title (EN) DISC DEVICE
(FR) DISPOSITIF A DISQUE
(JA) ディスク装置
Abstract: front page image
(EN)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).
(FR)L’invention concerne un dispositif à disque permettant de supprimer, par une configuration simple, le contact entre un moyen de maintien de disque et un disque. Un élément bloquant (3) monté sur le dispositif à disque maintient le disque durant sa rotation. Autrement dit, l’élément bloquant (3) est entraîné en rotation avec le disque. Lorsque l’axe central (Zc) de l’élément bloquant (3) coupe orthogonalement la direction (G) de la pesanteur et que l’élément bloquant (3) ne maintient pas le disque, la surface intérieure d’un trou de soutien (2h) du support (2s) de l’élément bloquant vient au contact d’une circonférence externe de l’élément bloquant (3) de manière à soutenir celui-ci. Sur la surface intérieure du trou de soutien (2h), deux moyens (CA, CB) de maintien de disque sont montés au-dessus de la partie inférieure (3L) de l’élément bloquant (3) par rapport à la direction (G) de la pesanteur. L’élément bloquant (3) est soutenu sur son support (2s) par le module de soutien des moyens (CA, CB) de maintien de disque.
(JA) 簡単な構成で、ディスク保持手段とディスクとの接触を抑制することを目的とする。このために、クランパ3は、ディスク装置に備えられるとともに、ディスクの回転時においてはディスクを保持して、ディスクとともに回転する。また、クランパ3の中心軸Zcと重力の作用方向Gが直交するようにディスク装置が設置されると、クランパ3がディスクを保持していない場合には、クランパホルダ2sの支持孔2hの内面がクランパ3の外周部と係合して、クランパ3を支持する。支持孔2hの内面には、重力の作用方向Gに対するクランパ3の最下点3Lよりも上の部分に、2個のディスク保持手段支持部CA、CBが設けられる。クランパ3は、このディスク保持手段支持部CA、CBでクランパホルダ2sに支持される。
