    • A disc loading mechanism for a optical disc drive,. The loading mechanism includes a chassis, loader tray, a linear gear bar, lifter, motor, gear train, and a sub-chassis. The pivoting sub-chassis, which supports an optical reader, rotates around a fixed axis and has 1-degree of freedom. The loader tray is slidably attached to the chassis such that it can move from a fully out-position, the position where a disc would be loaded, to a fully in-position, the position where the optical reader would engage the disc. The linear gear bar has a long rigid body with gear teeth along the length of its body. It is slidably attached to the loader tray and performs multiple functions including facilitating the movement of the loader tray, the lifting of the sub-chassis, and the timing of the loading mechanism.
    • 一种用于光盘驱动器的盘装载机构。 装载机构包括底盘,装载机托盘,线性齿条,升降机,马达,齿轮系和副底盘。 支撑光学读取器的枢转副底盘围绕固定轴线旋转并具有1度自由度。 装载机托盘可滑动地附接到底盘,使得其可以从完全向外的位置,即将被装载盘的位置移动到光学读取器将与盘接合的位置的完全就位。 线性齿条具有长的刚体,沿其主体的长度具有齿轮齿。 它可滑动地连接到装载机托盘,并且执行多种功能,包括促进装载机托盘的移动,副底架的提升以及装载机构的定时。
