IMAGING APPARATUS INCLUDING OPTICAL SCANNING DEVICE WITH DEFLECTING MIRROR MODULE, AND METHOD OF DEFLECTING WITH THE MIRROR MODULE

摘要

A module configured to deflect light in an image forming apparatus. A torsion bar supports a mirror and defines a rotational axis of the mirror. A controller is configured to apply electronic pulses to at least one driving device to oscillate the mirror in the module around the rotational axis at a scanning frequency different than a resonance frequency of the mirror.
