  • a tray 4 For supporting the disk when the spindle 2 is not in engagement with the disk, there is provided a tray 4 having an opening 5 allowing the passage of the spindle 2 and of the optical signals of the optical system 3.
  • the tray 4 is of the drawer type, that is the tray 4 is slidable between an open position outside a housing of the device allowing loading and unloading of a disk, and a closed position in which the disk is positioned with its hub substantially in alignment with the spindle 2.
  • a loader mechanism In order to bring the spindle 2 in engagement with the hub of the disk, there is provided a loader mechanism causing a relative movement between the spindle 2 and the tray 4, mainly in a direction perpendicular to the plane of the tray 4 and disk supported thereon.

  • the disk drive 1-3 is locked in its engaged/disengaged position, while the disk drive 1-3 is adjusted when the pins 17, 18 run through the intermediate part 23 of the curves 12, 13 as the control slide 9 is moved.
  • the curves 12, 13 in the sets 10, 11 are offset with respect to each other, both in the sliding direction of the control slide 9 and in the direction of movement of the disk drive 1-3.

It is noted that in specification and claims, the use of the expressions "a” or “an” does not exclude a plurality thereof, whereas the expression “comprising” does no exclude additional elements or steps. Any reference signs in the claims shall not be construed as limiting the scope thereof. A single processor or unit may fulfil the functions of several elements in the appended claims. In the presently preferred embodiments, the disk is an optical data disk. However, it should be understood that the invention can also be used for all kinds of other disks e.g.
  • the curves in each set may have different shapes, depending on the required movement of the disk drive and take-over of the pin operation.
  • a curve adjacent to an end of the control part may also be open towards this end such that a cooperating pin may leave the respective curve at this end as soon as the other pin-curve engagement in the set has taken over the control.
  • the curve will be open at its inclined portion and may have a "parallel" portion on one end only.

Abstract

Un dispositif de chargement pour unité de lecteur de disque comprend un lecteur de disque, un plateau pour porter un disque et un système de réglage pour déplacer le lecteur de disque vers et depuis le plateau et mettre ainsi le lecteur de disque en contact et hors contact du disque placé sur le plateau. Le système de réglage comprend des éléments en courbe et des broches en contact avec les éléments en courbe. Les broches et les éléments en courbe se situent respectivement sur le lecteur de disque et sur une unité de commande. Le système de réglage comprend un ensemble d'au moins deux éléments en courbe/contre-éléments coopérants, de sorte que les éléments en courbe soient ouverts sur au moins une extrémité et coopèrent avec les broches qui sont décalées dans la direction de déplacement du lecteur de disque vers et depuis le plateau. Ainsi, la broche individuelle vient en contact fonctionnel avec l'élément en courbe coopérant associé sur la moitié du déplacement relatif, la broche suivante étant en contact fonctionnel avec l'élément en courbe coopérant associé sur une autre partie du déplacement relatif. Ceci permet de réduire la hauteur des éléments en courbe, et par conséquent, celle du système de réglage.
