Abstract: It is an object of the present invention to provide an optical multi-beam scanning device and an image forming apparatus which adopt a horizontal synchronization sensor and can suppress displacement in a horizontal scanning direction even when latent images are written on a surface to be scanned by a plurality off light beams tilting with respect to the surface to be scanned. In the optical multi-beam scanning device of the present invention, when the light beams are assumed to reach the surface to be scanned with the light beams not being folded, the horizontal synchronization sensor is tilted so as to output a horizontal synchronized signal when the light beams come to the same position on the surface to be scanned in the horizontal scanning direction. In another method, the horizontal synchronization sensor is not tilted, and the similar function is executed by setting a boundary position between a shielding portion and a non-shielding portion of a light shielding member provided on an upper stream side.

Abstract: A device for deflecting a light beam in response to an audio input signal includes a hub member, a mirror flexibly attached to the hub member, a magnet connected to the mirror, an electromagnetic coil, and a low pass filter. The electromagnetic coil is positioned adjacent the magnet for producing an electromagnetic field in relation to a received audio input signal when energized, thereby urging the magnet and the mirror to oscillate with respect to the hub member in relation to the audio input signal. The low pass filter filters out audio input signal frequencies that would cause the mirror and the magnet to naturally resonate. The mirror may be attached at an offset angle that causes a light beam striking the mirror to be deflected angularly away from an axis of rotation passing through the hub member.

Abstract: In a reflecting-mirror supporting mechanism, elastic rotation about the lateral X axis is made possible by providing first spring elements 2 and second spring elements 3 in a bipod 1. In addition, elastic rotation about the lateral Y axis is made possible by a spring member 6, and elastically translational displacement along the axial Z axis is made possible by a parallel-spring member 9. The two legs of the bipod 1 are arranged with their upper ends getting close to each other with a predetermined distance at a tilt with respect to the axial Z axis. Variations in moment load generated in the reflecting mirror can be suppressed by making the intersecting point of the center axes of the two legs of the bipod 1 agree with the position of the center of gravity of the reflecting mirror.
