Image forming apparatus for cancelling non-uniform rotation of a rotating member |
摘要 |
An image forming apparatus having: a rotating member adapted to support an image; a first drive source configured to generate a drive force; a transmission mechanism configured to transmit the generated drive force toward the rotating member, the mechanism including an upstream gear and a downstream gear configured to receive the drive force therefrom; a sensor configured to output a signal indicating a rotational status of the rotating member; a control circuit configured to generate a control signal appropriate for non-uniform rotation of the rotating member, on the basis of the signal outputted by the sensor; and an actuator configured to cause a rotation axis of the first drive source or the transmission mechanism to pivot, in accordance with the control signal, thereby changing a force with which the upstream gear pushes the downstream gear into rotation such that the non-uniform rotation is cancelled out. |

1. An image forming apparatus comprising:
a rotating member adapted to support an image; a first drive source configured to generate a drive force; a transmission mechanism configured to transmit the drive force generated by the first drive source toward the rotating member, the mechanism including an upstream gear and a downstream gear configured to receive the drive force from the upstream gear; a sensor configured to output a signal indicating a rotational status of the rotating member; a control circuit configured to generate a control signal appropriate for non-uniform rotation of the rotating member, on the basis of the signal outputted by the sensor; and an actuator configured to cause a rotation axis of the first drive source or the transmission mechanism to pivot, in accordance with the control signal generated by the control circuit, thereby changing a force with which the upstream gear pushes the downstream gear into rotation such that the non-uniform rotation of the rotating member is cancelled out. |
