Claims

[Scope of Utility Model Registration Claim] A rotating member that is pressed against an information medium on which image information to be input is recorded and rotates in response to a relative displacement speed with the information medium, and an opening formed in a case from a light source. an image reading means for generating an image data signal from reflected light including the image information, which is irradiated with light toward the information medium through the aperture, and is incident through the aperture; and a rotation detector for detecting rotation of the rotating member. An image information input device comprising: a rotating member storage recess formed in the case to define the rotating member from an internal space of the case.
