摘要： A lens drive device capable of preventing a lens holder from inclining with respect to the optical axis direction of a lens is provided. A first gear (13), a second gear (14), a protrusion (20a), and a coil spring (6) are coaxially supported by a shaft (5), which is a fixed shaft. The rotational motion is transmitted to a two-stage gear (12) by rotating a rotor (11a) of a step motor (11) clockwise or counterclockwise. The rotational motion of the two-stage gear (12) is in turn transmitted to the first gear (13) and the second gear (14). When the first gear (13) and the second gear (14) rotate, the degree of engagement between an internally threaded portion (131a) of the first gear (13) and an externally threaded portion (141a) of the second gear (14) increases, and the second gear (14) moves upward. As the second gear (14) moves upward, a lens holder (20), urged upward by the elastic force of the coil spring (6), moves upward along the optical axis of a lens (21).

摘要： A step motor includes a rotor having four magnetic poles, a first magnetic pole magnetically excited by a first coil, a second magnetic pole magnetically excited by a second coil, and a third magnetic pole magnetically excited by the first coil and the second coil. A gap between the third magnetic pole and the rotor is smaller than that between the first magnetic pole and the rotor and that between the second magnetic pole and the rotor. In the step motor, it is possible to intensify the influence, on the rotor having four poles, of the magnetic fields created from three magnetic poles. Accordingly, this can weaken the magnetic fields set up from the first magnetic pole and the second magnetic pole, which tend to intensify the influence on the rotor, enabling the torque smaller at the time of the rotation start of the rotor.
摘要翻译：步进电动机包括具有四个磁极的转子，由第一线圈磁激励的第一磁极，由第二线圈磁激励的第二磁极和由第一线圈和第二线圈磁激励的第三磁极。第三磁极和转子之间的间隙小于第一磁极和转子之间的间隙以及第二磁极和转子之间的间隙。在步进电动机中，可以加强对由三个磁极产生的磁场的具有四个极的转子的影响。因此，这可以削弱从第一磁极和第二磁极设置的磁场，这倾向于加强对转子的影响，使得转子旋转时的转矩变小。
