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: 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 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.
