    • A focus adjusting device (50) for an image sensor (1) is provided for ensuring precise focusing of the image sensor. The focus adjusting device includes a contact element (51) in direct contact with the bottom of a scanner cover plate, a focus varying element (53) engaging with the contact element, and a focus fine adjusting element (55) movably mounted on a housing of the image sensor. The focus varying element and the contact element are driven to correspondingly move vertically together with the vertical movement of the focus fine adjusting element, whereby the distance between an upper surface of the housing and the bottom of the cover plate is thus changed for precise focusing.
    • 提供了一种用于图像传感器(1)的聚焦调节装置(50),用于确保图像传感器的精确聚焦。 焦点调节装置包括与扫描器盖板的底部直接接触的接触元件(51),与接触元件接合的聚焦改变元件(53)和可移动地安装在壳体上的聚焦微调元件(55) 的图像传感器。 驱动焦点变化元件和接触元件以随着焦点微调元件的垂直运动而垂直地移动,由此改变壳体的上表面与盖板的底部之间的距离,以进行精确的聚焦。
