    摘要: A vacuum pump includes a casing having an inlet port and an outlet port, a stator portion provided inside the casing and a rotor portion having a shaft rotatably supported inside the casing and a rotor disposed on the shaft and provided with a gas transfer mechanism that transfers a gas from the inlet port to the outlet port. The rotor portion is arranged with a predetermined clearance between the rotor portion and the stator portion. A motor rotates the shaft. Vibration detection disposed in the stator portion detects vibrations by converting vibration amplitude to an electric signal. Contact detection judges an occurrence of contact between the stator portion and the rotor portion when, in the vibration detected by the vibration detection, an amplitude in frequency of a specific vibration caused by contact between the stator portion and the rotor portion exceeds a predetermined threshold value.

    摘要: A sheet feeding device includes a sheet carrying unit, an attraction separation device electrostatically attracting and separating an uppermost sheet from a sheet stack and including multiple rollers, an endless dielectric belt stretched over the multiple rollers, and an elastic member provided inside a loop of the belt to cause the endless dielectric belt to contact the uppermost sheet, a sheet conveying device, and a lifting and lowering device. The lifting and lowering device lifts the sheet stack to a lift position at which the uppermost sheet contacts with the attraction separation device, and the attraction separation device stands by for a predetermined time to attract the uppermost sheet and starts to convey the uppermost sheet after the predetermined time elapses in a state in which the sheet stack remains at the lift position.

    摘要: An image forming apparatus includes an image forming device, a sheet feeding unit, a belt pressing member, and a moving unit. The sheet feeding unit includes an endless, dielectric belt to contact and attract the uppermost sheet to a surface thereof and feed in a sheet feeding direction, and an electric potential pattern forming unit to form an electric potential pattern on a surface of the dielectric belt. The moving unit moves the belt pressing member between a sheet attracting position and a sheet feeding position. The dielectric belt attracts the uppermost sheet at the sheet attracting position, the moving unit moves the belt pressing member to the sheet feeding position, and an entire flat portion of the dielectric belt feeds the uppermost sheet in the sheet feeding direction while carrying the uppermost sheet thereon as the dielectric belt rotates.
