Claims

[Scope of utility model registration request]

In an image input device that uses a straight tube fluorescent lamp as a light source, the light reflected from the document is focused on an image sensor using a lens, and a white level follower circuit follows the white level to determine the reading standard. An image input device equipped with a filter on the optical axis whose central portion has approximately half the light transmittance.
