Abstract
A multi-beam scanning apparatus includes at least two optical sources, a beam deflector having a deflection disc with a plurality of sectors for diffracting and transmitting incident beams, and a driving source for rotating the deflection disc, for deflecting and projecting beams emitted from the optical sources. A beam corrector installed along a light path, for correcting the beams deflected by the beam deflector.
Claims6
A multi-beam scanning apparatus comprising:
- at least two optical sources which emit beams of light;
- a beam deflector including a deflection disc having a plurality of sectors which diffract and transmit incident beams, and a driving source which rotates the deflection disc, for deflecting and projecting the beams emitted from the optical sources;
- and
- a beam corrector, installed along a light path, for correcting the beams deflected by the beam deflector,
- wherein at least one of the optical sources is installed so that a beam emitted from the one optical source is incident on a first sector of the deflection disc, and at least another optical source is installed so that a beam emitted from the other optical source is incident upon a second sector symmetrical to said first sector, and
- wherein the apparatus comprises at least two deflection discs, and the optical sources are disposed so that the emitted beams are incident intersectingly upon adjacent sectors of the deflection discs.

A multi-beam scanning apparatus comprising:
- at least two optical sources which emit beams of light;
- at least two deflection discs each including a plurality of sectors which diffract and transmit incident beams, and a driving source which rotates a corresponding one of the deflection discs, for deflecting and projecting the beams emitted from the optical sources;
- and
- beam correctors for correcting the beams deflected by the deflection discs, wherein the optical sources are disposed so that the emitted beams are incident intersectingly upon adjacent sectors of the deflection discs.
