摘要： A document scanning apparatus for scanning a document is provided. The document scanning apparatus includes an image sensor unit which irradiates an incident light towards the document and generates image data by sensing a reflected light reflected from the document, a supporting unit which supports the image sensor unit, a movement unit which moves the image sensor unit between a scanning position and a calibration position, a housing which houses the image sensor unit, the supporting unit, and the movement unit, a transparent plate which transmits the incident light and the reflected light, a calibration sheet which is attached to a surface of the transparent plate, which is exposed to outside and is positioned in an area including the calibration position, and a housing cover which is coupled to the housing and seals inside of the housing.

摘要： An image scanning device, an image forming apparatus including the image scanning device, and a method of controlling image quality in the image scanning device are provided. The image scanning device includes a document board on which documents to be scanned are placed, a scanning unit which is installed on a lower portion of the document board to be linearly reciprocated, and comprises a scanner including a light guide for irradiating light to the documents, and light emitting devices that are separated from both ends of the light guide and irradiate light, and an image sensor for receiving the light emitted from the scanning unit, wherein, loss of the light emitted from the light emitting devices is compensated for by increasing intensity of electric current supplied to the light emitting devices as a distance between the light emitting devices and the light guide increases.
