Abstract
Official abstract text for this publication.
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.
