Abstract
An optical system unit includes a light source to project a light onto a document, a plurality of reflecting mirrors to receive the light reflected from the document and forming a plurality of optical paths, a lens to form an image by focusing the light reflected from the reflecting mirrors at a focusing position thereof, and a reading unit disposed at the focusing position of the lens, wherein at least seven optical paths are formed between the document and the lens by the plurality of reflecting mirrors, and a first reflecting mirror that receives the light from the document along a first optical path is disposed lower than the other reflecting mirrors.

An image reading apparatus, comprising:
- a document tray mounted to a main body of the apparatus to position a document thereon;
- and
- an optical system unit having a light source, a plurality of reflecting mirrors, a lens, and a reading unit in communication with one another to read an image from the document,
- wherein at least seven optical paths are formed between the document and the lens by the plurality of reflecting mirrors, and a first reflecting mirror receives the light along a first optical path, which is perpendicular to the document and is disposed lower than the other reflecting mirrors.
1 more element
An image forming apparatus, comprising:
- a frame having a window on which a document is positioned;
- a light source disposed adjacent to the window to emit light toward the document;
- a mirror arrangement having a plurality of mirrors to fold a light beam reflected by the document such that the light beam is reflected by a selected one of the mirrors at least two times;
- and
- a reading unit disposed adjacent to the mirror arrangement to read the folded light beam.
2 more elements
An image forming apparatus, comprising:
- a frame having an input portion on which a document is positioned and an output portion;
- a light source disposed adjacent to the input portion to emit light to the document such that a light beam is reflected from the document into the input portion of the frame along an input axis;
- and
- a plurality of reflectors arranged about the input axis of the light beam to fold the light beam and to reflect the light beam toward the output portion along an output axis that is perpendicular to the input axis.
1 more element
An image reading apparatus, comprising:
- a frame having an entrance portion to receive a light beam containing image information along an entrance axis and an exit portion through which the light beam is output along an exit axis;
- and
- a first reflector disposed in the frame at an end of the entrance axis that is opposite to the entrance portion of the frame;
- at least one second reflector disposed on a first side of the entrance axis;
- at least one third reflector disposed on a second side of the entrance axis to reflect the light beam received from the first reflector to and from the at least one second reflector and to the exit portion of the frame;
- and
- a reading unit disposed at the exit portion to read the light beam received from the at least one third reflector.
4 more elements
