摘要： A drive transmission device, which is included in an image forming apparatus, includes a drive transmission body to which a drive force is applied from a driving source, and a rotary shaft having a press-in portion mounted on one end thereof in the axial direction. The press-in portion has multiple planes disposed parallel to an axial direction and configured to receive the drive transmission body. The multiple planes include upstream and downstream side planes disposed downstream from the upstream side plane in a press-in direction of the drive transmission body. The upstream and downstream side planes are aligned along the press-in direction of the drive transmission body and have respective distances different from each other from an axial center of the rotary shaft. A distance from the downstream side plane to the axial center is greater than a distance from the upstream side plane to the axial center.

摘要： A drive unit, which can be included in an image forming apparatus with peripherals disposed thereto and use a control method therefore, includes an inner rotor brushless DC motor, a driver, a rotation detector, and a controller. The driver supplies power to drive the brushless DC motor. The rotation detector detects an amount and direction of rotations of an output shaft. The controller controls the rotations of the brushless DC motor and obtains a target drive signal of the brushless DC motor externally and a detection signal from the rotation detector and outputs a signal to the driver. The controller controls a speed of rotation of the brushless DC motor by varying the signal output to the driver based on the target drive signal and the detection signal.

摘要： A clutch mechanism comprises a planetary gear unit including input transmission, output transmission, and transmission stopping members. Torque entering the input transmission member is outputted downstream of the planetary gear unit by the output transmission member when the transmission stopping member is fixed and is not outputted downstream when the transmission stopping member is unfixed and entering a rotatable state. A rotation prohibiting target has an engaging target and is integral with the transmission stopping member. A rotation prohibiting member has a supporting shaft, a swingable portion at its one end and an engaging portion at its other end to engage the engaging target to enable the transmission stopping member to exert the stopping function. The engaging portion disengages the engaging target to bring the transmission stopping member into an unfixed state. A damper unit absorbs vibration caused in the rotation prohibiting member during a switching operation.
