    • A disc centering device includes a base plate, a chuck which is installed on the base plate, a hub unit which is detachably engaged to the chuck and receives discs to be stacked, disc pushers which are slidably provided outside the hub unit and include corresponding pressure members which center the discs by pushing circumferences of the discs, and a driving unit which slides the disc pushers simultaneously. Accordingly, as the accuracy of centering the discs is improved, discs with data recorded thereon having a uniform quality can be obtained. Additionally, vibration of a rotation body can be minimized due to the simple configuration the disc centering device. Therefore, in view of the simplified maintenance and repair of the disc centering device, the productivity and manufacturability of HDDs can be improved.
    • 盘对中装置包括基板,安装在基板上的卡盘,可拆卸地接合到卡盘并容纳待堆叠的盘的轮毂单元,可滑动地设置在轮毂单元外部的盘推动器,并且包括相应的压力 通过推动盘的周向使碟片居中的构件,以及同时滑动盘推动器的驱动单元。 因此,随着盘的定心精度的提高,可以获得其上记录有数据的盘具有均匀的质量。 此外,由于盘定心装置的简单配置,旋转体的振动可以最小化。 因此,考虑到盘定心装置的简化维护和修理,可以提高HDD的生产率和可制造性。

    • A substrate inspecting apparatus to inspect a substrate printed on by a print head to determine whether a printing operation is being accurately performed includes a camera unit to photograph the substrate before the substrate is printed on and to photograph the substrate after the substrate is printed on, and a control part to compare a first image of the substrate before the substrate is printed on with a second image of the substrate after the substrate is printed on through the camera unit and to determine whether the printing operation is being accurately performed on the substrate. Thus, the substrate inspecting apparatus is capable of precisely inspecting the substrate during the printing operation and reducing processing time.
    • 一种基板检查装置,用于检查由打印头印刷的基板以确定是否正在准确地执行打印操作包括在印刷基板之前拍摄基板的相机单元,并且在印刷基板之后对基板进行拍摄, 以及控制部件,用于在将基板印刷之后的基板的第一图像与基板的第二图像之间进行比较,并且确定在基板上是否正确地执行打印操作。 因此,基板检查装置能够在打印操作期间精确地检查基板并减少处理时间。

    • A disc centering device includes a base plate, a chuck which is installed on the base plate, a hub unit which is detachably engaged to the chuck and receives discs and spacers to be stacked, disc pushers which are slidably provided outside the hub unit and include corresponding pressure members which center the discs by pushing circumferences of the discs, a driving unit which slides the disc pushers, and biasing units which are slidably provided outside the hub unit and push circumferences of the spacers. Accordingly, by performing a spacer biasing along with a disc centering, the accuracy of a centering is increased, thereby providing the discs having data recorded thereon with a uniform quality. Additionally, vibration of a rotation body can be minimized due to the simple configuration of the disc centering device. Furthermore, the productivity and manufacturability of HDDs are improved in view of the simplified maintenance and repair of the same.
    • 盘定心装置包括基板,安装在基板上的卡盘,可拆卸地接合到卡盘并容纳待堆叠的盘和间隔件的轮毂单元,可滑动地设置在轮毂单元外部的盘推动器,并且包括 相应的压力部件,其通过推动圆盘的圆周使圆盘对中,驱动单元,其使盘推动器滑动;以及偏压单元,其可滑动地设置在轮毂单元外部并推动间隔件的周向。 因此,通过与盘定心一起执行间隔件偏压,可以提高定中心的精度,从而提供具有以其均匀质量记录在其上的数据的盘。 此外,由于盘定心装置的简单配置,旋转体的振动可以最小化。 此外,为了简化维护和修理,HDD的生产率和可制造性得到改善。
