Abstract

A disclosed image scanning device illuminates a document with a light source, focuses light reflected from the document on an image sensor to obtain one-dimensional images of the document, and obtains a two-dimensional image of the document from the one-dimensional images. The device includes an illumination lens for dividing a light beam emitted from the light source into multiple light beams and a combining unit for combining the multiple light beams on the document. A disclosed image scanning method includes the steps of illuminating a document with a light source; focusing light reflected from the document on an image sensor to obtain one-dimensional images of the document; and obtaining a two-dimensional image of the document from the one-dimensional images. In this method, a light beam from the light source is divided into multiple light beams and the multiple light beams are combined on the document. A disclosed image forming apparatus includes the image scanning device.
