ことを特徴とする画像入力装置。[Claim for Utility Model Registration] Light from a light source is slit-exposed across the width of the document, and the light reflected on the surface of the document is incident on an image sensor via an imaging lens to optically image the contents of the document. In an image input device for reading images, a shading correction means constituted by a comb-like member having a large number of legs is connected between the light source and the image sensor so that the light from the light source is incident on the image sensor with a uniform amount of light. An image input device characterized in that the image input device is disposed on an optical path between the two.
