Abstract
Provided is a light scanning apparatus, including a light source, a light source controller to control an on/off operation of the light source, a light deflector deflecting light emitted from the light source, an image formation optical system to direct light deflected by the light deflector on a scan area of a to-be-scanned surface, a synchronous signal detector to receive the light emitted from the light source and to detect a synchronous signal for light scanning, and a light path changer changing a path of light emitted from the light source and incident upon the light deflector.
Claims11
A light scanning apparatus comprising:
- a light source that emits light in a first direction;
- a light source controller to control an on/off operation of the light source;
- a light deflector deflecting light emitted from the light source;
- an image formation optical system to direct light deflected by the light deflector on a scan area of a to-be-scanned surface;
- a synchronous signal detector receiving the light emitted from the light source and to detect a synchronous signal for light scanning;
- and
- a light path changer to change a path of light emitted from the light source and incident upon the light deflector, the light path changer comprising a first reflection mirror that reflects the light emitted from the light source and a second reflection mirror that re-reflects the light reflected by the first reflection mirror so that the re-reflected light advances toward the light deflector in a second direction, wherein the first and second directions are not parallel to one another.
A light scanning apparatus comprising:
- a light source;
- a light source controller to control an on/off operation of the light source;
- a light deflector for deflecting light emitted from the light source;
- an image formation optical system to direct light deflected by the light deflector on a scan area of a to-be-scanned surface;
- a synchronous signal detector receiving the light emitted from the light source and detecting a synchronous signal for light scanning;
- a first reflection mirror reflecting the light emitted from the light source;
- and
- a second reflection mirror re-reflecting the light reflected by the first reflection mirror so that the re-reflected light advances toward the light deflector, wherein a rectilinear line which extends in a direction of the light emitted from the light source is not parallel to a rectilinear line extending in a direction of the light incident upon the light deflector.
