摘要： A CPU determines that a motor is undergoing a forward rotation when a time difference between a detection timing of a light beam deflected by a rotating polygonal mirror and an output timing of a detection signal from a magnetic detector element falls within a predetermined range, and that the motor is undergoing a reverse rotation when the time difference does not fall within the predetermined range. With this configuration, a detection circuit for detecting voltage induced in three phases is unnecessary, and therefore the cost can be reduced. Furthermore, there is no need to detect voltage induced in each of the three phases. As it suffices to simply detect the time difference, the amount of time required to detect a rotation direction can be reduced.

摘要翻译： 当由旋转多面镜偏转的光束的检测定时与来自磁检测器元件的检测信号的输出定时之间的时间差落在预定范围内时，CPU确定电机正在正转，并且 当时间差不落在预定范围内时，马达正在进行反向旋转。 利用这种结构，不需要用于检测三相感应电压的检测电路，因此可以降低成本。 此外，不需要检测在三相中的每一个中感应的电压。 只要简单地检测时间差即可，可以减少检测旋转方向所需的时间。

摘要： A developing unit includes a developer storage unit, a developer bearing member, an agitation member, a flexible member, and a magnet member. The developer storage unit stores a developer. The developer bearing member develops an electrostatic latent image formed on an image bearing member with the developer. The agitation member agitates the developer in the developer storage unit. The flexible member, disposed in the developer storage unit, is distorted by pressure applied by the agitation member via the developer. The magnet member, disposed on the flexible member, is displaced in response to the flexible member being distorted.

摘要： A radio transmission apparatus performs peak suppression processing in the two stages of pre-peak suppression processing and post-peak suppression processing. The gain adjustment processing of transmission power is performed in the two stages of coarse gain adjustment processing, prior to the pre-peak suppression processing, and fine gain adjustment processing prior to the post-peak suppression processing. The fine gain adjustment processing has a smaller adjustment step width than the coarse gain adjustment processing, and can adjust the transmission power in response to a small variation of the transmission power. In the pre-peak suppression processing, a peak suppression value corresponding to the gain set by the coarse gain adjustment processing is set on the basis of each value being preset in a table for each transmission power value. In the post-peak suppression processing, the peak suppression value corresponding to the gain modified by the fine gain adjustment processing is obtained by calculation.
