Abstract
Provided are a scanning module and an image reading apparatus having the same. An alignment unit that can align positions of an image sensor and its tilt angles with regard to five degrees of freedom when a coupling position of an alignment member to a frame and a coupling position of a base plate to the alignment member are controlled, is provided, the image sensor can be aligned regardless of whether or not the production of the scanning module is completed, an alignment process is facilitated, and a manufacturing cost is reduce.
Claims20
A scanning module comprising:
- a frame in which a light source, a mirror and a focusing lens are disposed to form an optical path to read a document;
- a base plate to which an image sensor is attached, the image sensor receiving light focused by the focusing lens;
- an alignment member disposed between the focusing lens and the base plate;
- and
- an alignment unit to align positions and tilt angles of the image sensor with regard to five degrees of freedom by controlling a coupling position of the alignment member with respect to the frame and a coupling position of the base plate with respect to the alignment member.
An image reading apparatus comprising a scanning unit reading a document using a scanning module, the scanning module comprising:
- a frame in which a light source, a mirror and a focusing lens are disposed to form an optical path to read a document;
- a base plate to which an image sensor is attached, the image sensor receiving light focused by the focusing lens;
- an alignment member disposed between the focusing lens and the base plate;
- and
- an alignment unit to align positions and tilt angles of the image sensor with regard to five degrees of freedom by controlling a coupling position of the alignment member with respect to the frame and a coupling position of the base plate with respect to the alignment member.
A scanning module comprising:
- a light emitting body to emit light toward a document and to form an optical path along which the light propagates after being reflected from the document;
- a base plate to which an image sensor receiving the reflected light is attached;
- an alignment member disposed along the optical path upstream from the base plate;
- and
- an alignment unit to align positions and tilt angles of the image sensor with regard to five degrees of freedom by adjusting a position of the alignment member with respect to the frame and by adjusting a position of the base plate with respect to the alignment member.
An image forming apparatus to scan images from a document and/or to form images on the document, including a scanning module comprising:
- a light emitting body to emit light toward a document and to form an optical path along which the light propagates after being reflected from the document;
- a base plate to which an image sensor receiving the reflected light is attached;
- an alignment member disposed along the optical path upstream from the base plate;
- and
- an alignment unit to align positions and tilt angles of the image sensor with regard to five degrees of freedom by adjusting a position of the alignment member with respect to the frame and by adjusting a position of the base plate with respect to the alignment member.
