Abstract
Disclosed are a scanner and an image forming apparatus employing the same. The scanner may produce bidirectional scanning of light by oscillating a deflecting mirror about a first axis substantially parallel to the mirror surface, and may compensate for skewing of the scan lines by rotating the mirror about a second axis that is substantially perpendicular to the first axis so as to allow the light to be scanned at an angle.
Claims25
A scanner, comprising:
- a mirror;
- a rotational body spaced apart from and surrounding the mirror;
- a first bar connecting the mirror and the rotational body;
- and
- a driving unit configured to rotate the rotational body around an axis perpendicular to the mirror.
2 more elements
An image forming apparatus, comprising:
- a light source configured to produce a light beam;
- a scanner configured to receive the light beam from the light source and to deflect the received light beam across a scanning line;
- a photosensitive medium having a photosensitive surface upon which the light beam deflected by the scanner is incident to thereby form on the photosensitive surface an electrostatic latent image;
- a developing unit arranged adjacent the photosensitive member, the developing unit configured to apply developing agent to the photosensitive surface so as to develop the electrostatic latent image into a visible image;
- and
- a transfer unit configured to transfer the visible image onto a printing medium,
- wherein the scanner comprises:
- a mirror having a reflective surface;
- a rotational body spaced apart from and surrounding the mirror, the rotational body being configured to rotate about a rotational axis substantially perpendicular to the reflective surface of the mirror;
- a first bar connecting the mirror to the rotational body such that the mirror rotates together with the rotational body about the rotational axis;
- and
- a driving unit configured to drive the rotational body to rotate about the rotational axis.
9 more elements
A light scanning apparatus, comprising:
- a light source configured to generate light;
- and
- a mirror having a reflective surface upon which the light generated by the light source is incident, the mirror being configured to oscillate about a first axis substantially parallel to the reflective surface, the mirror being further configured to be rotatable about a second axis substantially perpendicular to the first axis.
