Abstract: An overhead image reading apparatus 1 includes: an image-capturing unit 22 that captures an image of a medium S to be read from above when the medium S to be read is placed on a placement surface 2; a light source 21 that irradiates the medium S to be read with light when the image-capturing unit 22 captures the image of the medium S to be read; and a light blocking portion 25 that blocks light above an upper-end position of light emitted from the light source 21. As a result, the user 100 can be prevented from seeing light from the light source 21 with his/her eyes and from being dazzled with an unpleasant feeling by light from the light source 21 during reading on the medium S to be read.

Abstract: A scanning apparatus comprises a transparent housing, a driving means arranged within the transparent housing, and an image sensor arranged within the transparent housing and driven by the driving means. The upper surface and the lower surface of the transparent housing are marked to define a transparent upper window and a transparent lower window. The image sensor comprises a contact image sensor and a supporting box for housing the contact image sensor. The small article to be scanned is facedown placed on the transparent upper window of the scanning apparatus when the scanning apparatus is in erect arrangement. The large article to be scanned is faced up placed and the user can align the scanning region through the transparent upper window and lower window. Therefore, the inventive scanning apparatus is applicable to scan article of both large and small size, and the transparent upper window and lower window facilitate the alignment of scanner for user for entire scanning or partial scanning of an article.
