摘要： A rotation number detector according to an embodiment is a rotation number detector that detects the number of rotations of a magnet attached to a rotating body by using a power generation unit. The power generation unit includes N (N is a natural number equal to or larger than 1) power generation elements, each including a magnetic wire in which magnetization reversal occurs due to a large Barkhausen effect and a pickup coil that is wound around the magnetic wire. The magnetic wire is longer than a wound portion of the pickup coil in an extension direction of the magnetic wire of the power generation elements. The magnetic wire is set above a rotation center of the magnet.

摘要： An encoder includes a first multiple rotation counter that generates first multiple rotation data using a rotation signal indicating one rotation of a rotational shaft of a motor, a second multiple rotation counter that generates second multiple rotation data using the rotation signal, a first cumulative-number calculation unit that calculates first accumulated multiple rotation data using an angle signal indicating a rotational angle of the rotational shaft, a second cumulative-number calculation unit that calculates second accumulated multiple rotation data using the angle signal, and a first comparative diagnosis unit that diagnoses whether the encoder has a fault by performing a comparison to determine whether the first multiple rotation data, the second multiple rotation data, the first accumulated multiple rotation data, and the second accumulated multiple rotation data are a same value.

摘要： An image forming apparatus which is capable of reducing first print output time and preventing slack of an intermediate transfer belt in a monochrome mode. Surfaces of photosensitive drums are electrically charged and exposed to light, thereby allowing electrostatic latent images to be formed thereon. Developers are attached to the electrostatic latent images to form visible images transferred to the intermediate transfer belt. Among the photosensitive drums, a photosensitive drum used in the monochrome mode and the intermediate transfer belt are rotatably driven by a first rotatably driving unit, and photosensitive drums other than the photosensitive drum used in the monochrome mode are driven by a second rotatably driving unit. In the monochrome mode, the rotational speed of the second rotatably driving unit is controlled so as to be equal to or less than that of the first rotatably driving unit without adjusting rotation phases of the photosensitive drums.
摘要翻译：一种能够在单色模式下减少第一打印输出时间并防止中间转印带松弛的图像形成装置。感光鼓的表面被带电并暴露于光，从而允许在其上形成静电潜像。显影剂附着到静电潜像上以形成转移到中间转印带的可见图像。在感光鼓中，以单色模式使用的感光鼓和中间转印带由第一可旋转驱动单元旋转驱动，并且除了在单色模式中使用的感光鼓之外的感光鼓由第二可旋转驱动单元驱动。在单色模式中，第二可旋转驱动单元的旋转速度被控制为等于或小于第一可旋转驱动单元的旋转速度，而不调节感光鼓的旋转相位。
