摘要： An optical scanning unit includes a rotatable multi-faceted mirror having a plurality of faces reflecting light flux emitted from a light source to scan a scanning area in a main scanning direction. A width of the light flux striking the rotatable multi-faceted mirror is smaller than a length of a face of the rotatable multi-faceted mirror. The entire of light flux striking the rotatable multi-faceted mirror is reflected at a first face when the light flux reflected by the rotatable multi-faceted mirror is directed to the center portion of the scanning area. A part of the light flux striking the rotatable multi-faceted mirror is reflected at the first face while the remaining of the light flux is reflected at a second face when the light flux reflected by the rotatable multi-faceted mirror is directed to a least one of the two end portions of the scanning area.

At least one surface of the scanning lens has multiple refracting surfaces arranged side by side in the sub-scanning direction, and each of the refracting surfaces has a positive refracting power in the sub-scanning direction, and vertices of the refracting surfaces are shifted in the sub-scanning direction from intersections of the light beams with the refracting surfaces toward the center of the scanning lens.

摘要： Synchronization detecting units detect synchronization signals by receiving the light beam deflected to one side of a light source on one side of an optical deflector and receiving the light beam deflected to an opposite side of an optical axis of a scanning optical system from the light source on the other side of the optical deflector. Photodetectors that detect the synchronization signals are arranged on the opposite side of an optical axis of a scanning optical system from the light sources and on a side closer to the scanning optical system that detects the synchronization signals by receiving the light beam deflected to the light source.

摘要： A display device includes a screen to form an intermediate image with light; a concave mirror, and a first mirror disposed between the screen and the concave mirror. The first mirror includes a first reflective area to reflect the light emitted from the screen to the concave mirror; a second reflective area to reflect the light emitted from the concave mirror to an area where a virtual image is formed; and a common reflective area in which the first reflective area and the second reflective area at least partly overlap on each other.
