摘要： PROBLEM TO BE SOLVED: To provide a structure which effectively absorbs stress caused in the fitted part of a polygon mirror and a rotor boss which are shrink-fitted in a polygon mirror scanner motor used for a laser scanning of such a copy machine as a laser beam printer or a laser beam copy machine. SOLUTION: The rotor boss 2 and the mirror 3 both have a fitting interference, the mirror 3 is heated to be expanded and inserted into the rotor boss 2 to be shrink fitted. In this case, stress is generated in the fitted part 4 due to the fitting interference, but the fitting part 4 is easily elastically deformed by providing flutes 3c at the central hole part of the polygon mirror. Thus, the influence of the stress at the fitted part 4 to the strain of the whole mirror is prevented and the strain of a mirror face 3a which affects laser scanning accuracy is effectively reduced. Further, the strain of the whole mirror is more effectively suppressed by providing the flutes 3c to be located at the edge part 3b between mirror faces. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供一种结构，其有效地吸收在用于这种复印机的激光扫描的多面镜扫描器电机中收缩配合的多面镜和转子凸台的嵌合部分引起的应力作为激光束打印机或激光束复印机。解决方案：转子凸台2和反射镜3均具有配合干扰，反射镜3被加热膨胀并插入转子凸台2以进行收缩装配。在这种情况下，由于配合干扰，嵌合部4产生应力，而是通过在多面镜的中心孔部分设置槽纹3c来容易弹性变形。因此，防止了装配部分4处的应力对整个反射镜的应变的影响，并且有效地降低了影响激光扫描精度的镜面3a的应变。此外，通过将凹槽3c设置在镜面之间的边缘部3b处，可以更有效地抑制整个反射镜的应变。版权所有（C）2006，JPO＆NCIPI
