An optical disk device for correctly positioning on a turntable, an optical disk composed of two optical disks glued together, regardless of how poorly they are attached together. The device includes the turntable, on which the optical disk is placed, a disk holding part onto which a mounting hole of the optical disk is fitted, and a clamping member, which is provided on part of the circumferential surface in the disk holding part, is free to move in the radial direction of the disk holding part, and is impelled radially outward. The clamping member is formed in a mountain shape by two sloping faces and a sloping faces meet. The tip is beveled to a shape such that the tip makes a surface contact with the optical disk when the optical disk is mounted on the turntable.
La présente invention concerne un dispositif à disque optique permettant de positionner correctement sur un plateau de chargement un disque optique composé de deux disques optiques collés ensemble, même s'ils sont peu collés l'un à l'autre. Ce dispositif comprend le plateau, sur lequel est placé le disque optique, une partie support de disque contenant un trou de montage de disque optique, et un élément de fixation situé sur une partie de la surface périphérique de la partie support; cet élément de fixation qui est libre de se déplacer radialement est amené radialement vers l'extérieur. En outre, l'élément de fixation est conçu sous forme de montagne composée de deux versants et d'une surface de contact. Le sommet est biseauté de manière à former un contact de surface avec le disque optique lorsque ce dernier est placé sur le plateau de chargement.
