摘要： A rotator control device includes drivers to drive rotators for sheet conveyance, respectively; and a processor including a selector to select, from the rotators, a pair of a first rotator subjected to rotation speed adjustment and a second rotator adjacent to the first rotator, and an acquisition unit to acquire a torque-related value representing a driving torque value of a driver to drive the second rotator or a value proportional thereto. The processor further includes a speed adjuster to adjust a rotation speed of the first rotator to approximate a variation in the torque-related value to zero. The selector selects a subsequent pair after adjustment of the rotation speed, designates the first rotator of the preceding pair as the second rotator of the subsequent pair, and selects, as the first rotator, a rotator adjacent to the first rotator of the preceding pair, opposite the second rotator of the preceding pair.

摘要： A rotating member control device that controls a first rotating member and a second rotating member to convey a sheet includes a processor configured to execute a program to implement processes of controlling the first rotating member and the second rotating member to come into contact or be separated from each other and acquiring a value that corresponds to or is proportional to a driving torque of a first driving unit that rotationally drives the first rotating member. The processor acquires the value upon separation when the first rotating member and the second rotating member are separated from each other and upon conveyance when the sheet is held between and conveyed by the first rotating member and the second rotating member. The processor further sets a rotational speed of the second rotating member such that the value acquired upon separation and the value acquired upon conveyance become equal.

摘要： A pump includes an impeller for sucking and discharging liquid, a pump case having a suction port and a discharge port through which the liquid is sucked and discharged, and a partition cooperating with the pump case to form a pump chamber in which the impeller is rotatably received. The pump is further includes a rotor having a magnet for rotatingly driving the impeller and a stator having claw-shaped magnetic poles for applying a rotational driving force to the rotor, the rotor and the stator constituting a claw pole type motor that serves as a driving power source of the pump. At least the stator is entirely coated with a molded resin.
