摘要： PROBLEM TO BE SOLVED: To suggest a structure in which a eccentricity and variation in balance are prevented by fixing a polygon mirror and a rotor boss by the inner pressure of a spring in a polygon mirror scanner motor used for a laser scanning of a laser beam printer or a laser beam copy machine. SOLUTION: The deviation of the rotating axes of the rotor boss 2 and the mirror 3 is prevented by the expanding effect of fixing the mirror 3 by uniformly expanding the outer diameter of the rotor boss 2. Further, a gap does not exist because the rotor boss 2 is made tightly contact with the inner diameter of the mirror 3, and the variation in imbalance is reduced even when an impulsive force is applied.

摘要： PROBLEM TO BE SOLVED: To suggest a structure in which stress is effectively absorbed at a fitting part at which a polygon mirror and a rotor boss are thermally inserted and fixed in a polygon mirror scanner motor used for a laser scanning in a laser beam printer or a laser beam copying machine. SOLUTION: A fitting margin is provided between the rotor boss 2 and a mirror 3, and the mirror 3 is expanded by heating and thermally inserted onto the rotor boss 2 and fixed. In this case, stress is generated at the fitting part 4 due to the fitting margin, and the fitting part 4 is easily elastically deformed with an annular groove 2a provided on the rotor boss 2 and an annular groove 3b provided on the mirror. Thus, an influence of the stress of the fitting part 4 to strain of the whole mirror is prevented, the strain of a mirror face 3a which affects laser scanning accuracy is effectively reduced. The windage loss and noise of a rotating motor at a high speed are reduced by making the annular groove 3b unexposed to the outside of the motor. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提出在多面反射镜和转子凸台被热插入并固定在用于激光扫描的激光扫描仪的多面镜扫描器电机的配合部分处有效地吸收应力的结构光束打印机或激光束复印机。解决方案：在转子凸台2和反射镜3之间设置安装边缘，并且反射镜3通过加热膨胀并热插入到转子凸台2上并固定。在这种情况下，由于配合余量，在配合部4产生应力，并且嵌合部4容易地与设置在转子凸台2上的环状槽2a和设置在反射镜上的环状槽3b弹性变形。因此，防止了装配部4的应力对整个反射镜的应变的影响，有效地降低了影响激光扫描精度的镜面3a的应变。通过使环形槽3b未暴露于电动机的外部，高速旋转电动机的风阻损失和噪声降低。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To solve the problem of a polygon mirror scanner motor that the coaxiality of a rotating shaft and a polygon mirror is deteriorated when the rotating shaft and a rotor boss on which the polygon mirror is fixed have an interference-fitted structure because the inner diameter of the polygon mirror is inevitably made larger when the variance of the expansion of the rotator boss is large. SOLUTION: A groove 2a is provided on the rotor boss 2 at the fitted part of the rotating shaft 1 and the rotor boss 2 so that the rotor boss is not brought into contact with the rotating shaft 1 even after fitted. The fitted part 2b of the polygon mirror is formed on the extended line of the groove 2a in a radial direction, thus the stress which the rotator boss 2 receives from the rotating shaft 1 is not directly transmitted and the deformation of the fitted part 2b of the polygon mirror is suppressed.

摘要翻译：解决的问题：为了解决当旋转轴和固定有多面镜的转子凸台之间的旋转轴和多面镜的同轴度降低的多面镜扫描器电动机的问题，由于当转子凸台的膨胀变化大时，多角镜的内径不可避免地会变大，因此，解决方案：即使在安装之后，转子凸台2在旋转轴1和转子凸台2的配合部分处设置有凹槽2a，使得转子凸台也不与旋转轴1接触。多面镜的嵌合部2b沿径向方向形成在槽2a的延长线上，因此转子凸台2从旋转轴1接收的应力不会直接传递，并且嵌合部2b的变形多边形镜被抑制。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that the inertia of a rotor boss influences the responsiveness at a high speed rotating range of 30,000 min -1 or higher, being compatible with a variety of polygon mirrors while providing the standardization of polygon mirror scanner motors. SOLUTION: A circular peripheral groove 3a formed on the bottom face of the polygon mirror 3 and a plurality of projected parts 4a formed on a virtual circle which is coaxial with the circular peripheral groove 3a and has a same diameter as that of the circular peripheral groove 3a on the upper face of a rotor frame 4 are faced and engaged to each other, the polygon mirror 3 is fixed to the rotor part by using a pressing spring 5 and a C-ring 6, thus a rotor boss is dispensed with and components are commonly used regardless the inner diameter dimension of the polygon mirror 3. Further, the inertia of the rotor boss is reduced and the high speed responsiveness of the motor is improved. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a polygon mirror scanner motor employed in a digital copier, a laser beam printer, or the like, and used for deflection scanning of laser beam in which positional stability is ensured in the axial direction without worsening the motor characteristics, and reliability of a bearing is enhanced while reducing noise and thickness.
SOLUTION: Since a thrust magnet 17 subjected to unipolar magnetization in the axial direction is arranged on the backside of a thrust cover 16 on the outside of a bearing, magnetic attraction takes place between the thrust magnet 17 and a rotating shaft 13 made of a magnetic material to ensure stability in the axial direction, and thereby a polygon mirror scanner motor produces stabilized rotational operation even for vibration/impact. High reliability is attained because a magnetized thrust magnet 17 is fixed to the backside of the thrust cover 16 after the bearing is assembled, and thereby no dust such as magnetic powder intrude into the bearing.

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
