    • A disc chucking apparatus for seating a disc on a turntable in the rotatable state and a disc player having such a disc chucking apparatus is provided. The disc chucking apparatus includes a chuck bracket having a clamper for clamping a disc to a turntable; and a lifting/lowering unit for lifting or lowering the chuck bracket to move the disc to a clamping position where the disc is seated on the turntable in the rotatable state or to a clamping standby position where the disc is separated from the turntable. The lifting/lowering unit includes: a first protrusion part formed at one of first and second ends of the chuck bracket; and a first slider having a first guide slot part formed to be opposite to the first protrusion part so that the first guide slot part receives and guides the first protrusion part to lift or lower the chuck bracket, wherein the first slider is mounted to be capable of reciprocating in the disc loading direction and selectively connected to a power transmission unit, which transmits power from a driving motor, depending on its moving position, thereby being reciprocated. According to the present invention, because the chuck bracket for fixing a clamper for clamping a disc is directly driven by the first slider which is selectively connected to a power transmission unit and reciprocated without intervention of a separate power transmission member such as a subordinate chassis, power transmission to the chuck bracket is smooth and the operation of the chuck can be smoothly executed.
    • 提供一种用于将盘安装在可旋转状态的转盘上的盘夹持装置和具有这种盘夹持装置的盘播放器。 盘式夹紧装置包括具有用于将盘夹持到转盘的夹持器的卡盘托架; 以及用于提升或降低卡盘托架以将盘移动到盘在可旋转状态下位于转盘上的夹紧位置或盘与转盘分离的夹紧待机位置的提升/降低单元。 提升/降低单元包括:形成在卡盘托架的第一和第二端中的一个上的第一突出部分; 以及第一滑块,具有形成为与所述第一突出部相对的第一引导槽部,使得所述第一引导槽部接收并引导所述第一突起部以提升或降低所述卡盘托架,其中所述第一滑块被安装成能够 在盘装载方向上往复运动并选择性地连接到动力传递单元,该动力传递单元根据其移动位置从驱动马达传递动力,从而往复运动。 根据本发明,由于用于固定用于夹持盘的夹持器的卡盘托架由第一滑块直接驱动,第一滑块选择性地连接到动力传递单元并且在不介入诸如下属底盘的单独的动力传递构件的情况下往复运动, 卡盘支架的动力传动平稳,卡盘的操作可以顺利执行。
