摘要:
PROBLEM TO BE SOLVED: To provide an optical resolution switching method by which the failure of an image caused at the gap of a lens fixing position is prevented from occurring.
SOLUTION: A CCD 9 is arranged at the back part of a first low-resolution lens 1 as an initial set position. After the focus of the lens 1 and a read position by the CCD 9 are adjusted, a CCD holder 5 is carried by a driving part 6 through a ball screw 7. Then, the holder 5 is stopped at a position set on the back optical axis of a second high-resolution lens 2 selected by the CCD 9 fitted to the holder 5. Therefore when the optical axes of the CCD 9 and the lens 2 in the X and the Y directions are not aligned, the optical axes are adjusted by rotating a second lens holder 4 in the X and the Y directions by turning adjustment screws 11 arranged at the left and the right sides of the lens 2. Then, the lens 2 and the holder 4 are fixed.

要解决的问题:提供一种防止在透镜固定位置的间隙引起的图像的故障的光学分辨率切换方法。 解决方案:CCD9设置在第一低分辨率透镜1的后部,作为初始设定位置。 在透镜1的焦点和CCD 9的读取位置被调节之后,CCD保持器5通过滚珠丝杠7由驱动部分6承载。然后,保持器5停在设置在背面光学 由安装在保持器5上的CCD 9选择的第二高分辨率透镜2的轴线。因此,当CCD 9和透镜2在X和Y方向上的光轴未对准时,光轴被调整为 通过转动布置在透镜2的左侧和右侧的调节螺钉11,在X和Y方向上旋转第二透镜架4.然后,透镜2和保持器4被固定。
