摘要： To eject a transfer tray while no disc is played, the transfer tray is moved to an ejected position with a rotary table rotated through an angle corresponding to 1/10 revolution, so that even the rearmost disc holding portion on the rotary table sufficiently projects or is exposed out of a body of the device. This permits simultaneous disc replacement for the disc holding portions. To eject the transfer tray during playing of a disc, the transfer tray is moved to the ejected position without the rotary table being rotated, so that the rearmost disc holding portion on the rotary table does not sufficiently project out of the body of the device, permitting disc replacement only for the other disc holding portions than the rearmost disc holding portion.
摘要翻译：要在没有播放光盘的情况下弹出传输托盘，传送托盘将移动到弹出位置，旋转台旋转一个与+ E，1/10 + EE旋转相对应的角度，以便即使最后面的光盘保持部分旋转台足够地突出或暴露在设备的主体之外。这允许光盘保持部分的同时盘更换。为了在播放光盘期间弹出传送托盘，传送托盘移动到弹出位置，而旋转台不旋转，使得旋转台上的最后盘保持部分不能充分伸出设备的主体，仅允许对最后盘片保持部分的其它盘保持部分的盘更换。

摘要： A disc playback device capable of continuously playing back a plurality of discs such as Compact Discs includes a main body, a tray movable relative to the main body for being received in and drawn out of the main body, a rotary table mounted rotatably on the tray, and a plurality of disc holding sections formed about a rotation axis of the rotary table. A turntable, a disc clamper and a reproducing head are provided in the main body separately from the tray. A recess is formed in the radial direction of the rotary table in each disc holding section and opens outwardly at the outer periphery of the rotary table. A disc mounting mechanism is provided for setting a disc held in the disc holding section on the turntable and clamping it by the disc clamper. The tray is formed with an opening communicating with the recess of the disc holding section in a disc playback position. The tray can be drawn out of the main body by keeping clear of the turntable and the reproducing head through the recess of the disc holding section and the opening of the tray while the disc is being played back. The disc holding sections hold discs in an inclined position in the circumferential direction of the rotary table and presence or absence of discs is detected by a reproducing head when the rotary table is rotated. While the tray is moved in and out of the main body, a pickup servo gain is increased to stabilize playback of a disc while the tray is being moved.
摘要翻译：能够连续地回放诸如光盘的多个盘的光盘播放装置包括主体，相对于主体可移动的托盘，用于容纳在主体中并从主体中拉出;旋转台，可旋转地安装在托盘上以及围绕旋转台的旋转轴线形成的多个盘保持部。转盘，盘夹持器和再现头与托盘分开设置在主体中。在每个盘保持部分中在旋转台的径向方向上形成凹部，并且在旋转台的外周向外敞开。提供了一种盘安装机构，用于将保持在盘保持部分中的盘设置在转盘上并由盘夹持器夹持。托盘形成有在光盘播放位置与盘保持部的凹部连通的开口。当盘被回放时，托盘可以通过盘片保持部分的凹部和托盘的开口保持远离转盘和再现头部而被拉出主体。盘保持部在旋转台的圆周方向上保持在倾斜位置的盘，并且当旋转台旋转时由再现头检测到盘的存在或不存在。当托盘移入和移出主体时，增加拾取器伺服增益，以在托盘移动期间稳定盘的回放。

摘要： A disc player, for playing various information carrier discs, which includes, a single turntable for supporting an information carrier disc, a single drive motor for rotating the turntable, and a reproducing head device for reading signals recorded on the disc. The drive motor has a motor body and a rotation shaft, and is attached at its rotation shaft directly to the turntable with its motor body spaced apart from the turntable. Therefore, a clearance is formed between the motor body and the turntable. The reproducing head device is radially transferrable relative to the turntable. When the reproducing head device is transferred to its innermost position where it reads the signals recorded on the inner periphery of the information area of the disc, it is positioned in the clearance without butting against either the motor body or the turntable.
摘要翻译：用于播放各种信息载体盘的光盘播放器，其包括用于支持信息载体盘的单个转盘，用于旋转转盘的单个驱动马达，以及用于读取记录在盘上的信号的再现头装置。驱动电动机具有电动机主体和旋转轴，并且其旋转轴直接连接到转盘，其电动机体与转台间隔开。因此，在电动机主体和转盘之间形成间隙。再现头装置可相对于转盘径向转移。当再现头装置被转移到其最内部位置时，其读取记录在盘的信息区域的内周上的信号，它被定位在间隙中，而不是对着电动机主体或转台。
