摘要： A sheet feeding tray includes a frame member, and freely upwardly swingable plural bottom plates arranged on the frame member side by side perpendicular to a sheet feeding direction. The bottom plates cooperatively support a stack of envelope recording mediums. A lifting device having plural curvature sections is provided. The plural curvature sections are respectively arranged below the bottom plates to scuff and lift the lower surface of the plural bottom plates at a section downstream of the sheet feeding direction. The plural curvature sections each include a different outline in accordance with a difference of a decreasing amount of a thickness of the stack during sheet feeding. The different outlines enable the topmost surface of the stack to be almost horizontal.
摘要翻译：供纸托盘包括框架构件，并且在垂直于片材进给方向并排设置在框架构件上的可自由向上摆动的多个底板。底板协同支撑一叠信封记录介质。提供具有多个曲率部的提升装置。多个弯曲部分分别布置在底板的下方，以在片材进给方向下游的部分进行擦拭并提起多个底板的下表面。多个曲率部分根据片材进给期间堆叠厚度的减少量的差异而包括不同的轮廓。不同的轮廓使堆叠的最上面几乎是水平的。

摘要： An aperture apparatus includes a substrate having a lens opening, a first aperture sector having a first aperture opening, a second aperture sector having a second aperture opening, and a drive pin that is engaged in cam openings respectively formed in the first aperture sector and in the second aperture sector and that swings the first aperture sector and the second aperture sector. The first aperture sector and the second aperture sector are located in receding positions from the lens opening, when the drive pin is in an initial position. The cam openings include a swing region and a non-swing region, the swing region guiding a corresponding sector to the lens opening as the drive pin moves from the initial position, the non-swing region retaining the other sector in the receding position, when one of the first aperture sector and the second aperture sector is guided to the lens opening.
摘要翻译：孔设备包括具有透镜开口的基板，具有第一开口开口的第一开口扇区，具有第二孔开口的第二开口扇区和与分别形成在第一开口扇区中的凸轮开口接合的驱动销，第二光圈扇区，并使第一光圈扇区和第二光圈扇区摆动。当驱动销处于初始位置时，第一光圈扇区和第二光圈扇区位于透镜开口的后退位置。凸轮开口包括摆动区域和非摆动区域，当驱动销从初始位置移动时，摆动区域将相应扇区引导到透镜开口，非挥发区域将另一个扇区保持在后退位置，当将第一光圈扇区和第二光圈扇区中的一个引导到透镜开口。

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。

摘要： A sector drive mechanism includes an electromagnetic actuator including a rotor having four polarities, a C-shaped stator, and a current control portion that controls current applied to a first coil and a second coil, the C-shaped stator including a first magnetic pole magnetically excited by the first coil, a second magnetic pole magnetically excited by the second coil, and a third magnetic pole magnetically excited by the first coil and the second coil, and sectors that are connected to the electromagnetic actuator to open and close a shutter opening provided in a substrate. The first coil and the second coil are driven to close the shutter opening with a fewer number of pulses applied from the current control portion than the number of the pulses to open the shutter opening.
