    • A disc player and changer mechanism adapted for use in a jukebox comprises a disc carrier which has a clamping arm movably mounted thereto, a translating tower and a drive system operable to move the carrier and/or the translating tower. The clamping arm includes a first disc engaging portion at one end thereof, which is positioned substantially opposite to a second disc engaging portion of the disc carrier. The disc carrier is slidably mounted on the translating tower and the clamping arm is movable as the disc carrier is moved on the translating tower such that the first disc engaging portion moves to contact an edge of a disc while the second disc engaging portion correspondingly contacts the edge of the disc substantially diametrically opposite of the first disc engaging portion. The disc is thus positively secured between the first and second disc engaging portions and may be transported from its initial position to a disc playing mechanism in a conventional manner. Preferably, the translating tower includes a magnetic hub assembly which is mechanically operable to engage a magnetic hub with the disc as the disc is positioned substantially adjacent to the player mechanism. The magnetic hub assembly is pivotally attached to the translating tower and operable by a stationary extension contacting a portion of the magnetic hub assembly as the translating tower approaches the disc player mechanism.
    • 适用于自动点播机的盘片播放器和变换器机构包括具有可移动地安装在其上的夹持臂的平台托架和可移动托架和/或平移塔的驱动系统的盘托架。 夹持臂包括在其一端处的第一盘接合部分,其位于与盘片托架的第二盘啮合部分基本相对的位置。 盘式托架可滑动地安装在平移塔上,并且当托架在平移塔上移动时,夹持臂可移动,使得第一盘接合部分移动以接触盘的边缘,而第二盘啮合部分相应地接触 所述盘的边缘基本上与所述第一盘接合部分直径相对。 因此,盘被牢固地固定在第一和第二盘接合部分之间,并且可以以常规方式从其初始位置传送到盘播放机构。 优选地,平移塔包括磁性轮毂组件,当磁盘基本上邻近玩家机构定位时,磁性轮毂组件可机械地操作以将磁性毂与盘接合。 磁性轮毂组件枢转地附接到平移塔,并且当平移塔接近盘片播放器机构时,通过接触磁性轮毂组件的一部分的固定延伸部可操作。
