    • A disk playback apparatus with a centering mechanism for positioning a small or a large disk which comprises a support frame, a clamper arm swingably mounted on a rear portion of the support frame, and a centering mechanism for guiding large and a small diameter disks from a front side of the playback apparatus to a position between the support frame and the clamper arm when the disk is inserted into the playback apparatus. The centering mechanism has a pair of centering arms for contacting with a circumferential edge of the disk for positioning the disk in place, a centering lever provided in the clamper arm and connected to the pair of centering arms for simultaneously opening/closing the pair of centering arms, and lock arms each rotatably mounted on the associated centering arm for locking the centering arm independently, the lock arms allowing the pair of centering arms to be swingable when both the lock arms are released. This playback apparatus can center both the small and large size disks at a clamp position.

    • A disk changer stably maintains a tray with a selected disk loaded thereon even if a physical impact or vibration is loaded from outside therein while the tray is being drawn out, the disk is being reproduced, or the tray is being retained. The disk changer has a retaining device which retains therein a plurality of trays each for loading a disk thereon at corresponding retaining positions parallel to each other in a horizontal state and also draws each tray out from the retaining position in the substantially horizontal direction, a guide member provided at a position corresponding to the retaining position, a tray moving mechanism engaging with a tray selected from the plurality of trays, causing the selected tray to engage with the guide member, and drawing out the selected tray partially or entirely from the retaining device in the substantially horizontal direction to move the tray to a position corresponding to the selected tray, a driving device which drives a disk on the selected tray drawn out to the drawing-out position, having a tray loading section for loading thereon the selected tray, and the guide member engages with the selected tray when the selected tray is drawn out by the tray moving mechanism, and elastically maintains the selected tray on a plane substantially identical to that of the corresponding retaining position collaborating with the retaining device and/or the tray loading section.
    • 即使在托盘被拉出,盘被再生或托盘被保持的情况下,即使从外部加载物理冲击或振动,盘式更换器稳定地保持其中装载有选定盘的托盘。 换盘器具有保持装置,该保持装置在其中保持有多个托盘,每个托盘用于在水平状态下以相互平行的相应保持位置装载盘,并且还在大致水平的方向上将每个托盘从保持位置拉出;导向件 设置在与所述保持位置对应的位置处的托盘移动机构,与从所述多个托盘中选择的托盘啮合,使所述托盘与所述引导构件接合,并且将所述托盘部分地或全部地从所述保持装置拉出 在基本上水平的方向上将托盘移动到与所选择的托盘相对应的位置,驱动装置将驱动装置从驱动装置驱动所选择的托盘拉出到拉出位置的盘,具有用于在其上装载所选托盘的托盘装载部分, 并且当所选择的托盘被托盘移动机构拉出时,引导构件与所选择的托盘接合,并且ela 将所选择的托盘牢固地保持在与保持装置和/或托盘装载部分协作的相应保持位置的平面上基本相同的平面上。
