摘要：
An image reading apparatus includes a light source for irradiating a document sheet with light, a row of red light receiving elements arranged in a primary scanning direction for detecting a red component of the light reflected on the document sheet, a row of green light receiving elements arranged in the primary scanning direction for detecting a green component of the reflected light, and a row of blue light receiving elements arranged in the primary scanning direction for detecting a blue component of the reflected light. The row of red light receiving elements, the row of green light receiving elements and the row of blue light receiving elements are displaced from each other in a secondary scanning direction which is perpendicular to the primary scanning direction.
