Patent ID: 7227978

Claim:
An image input device comprising: a transparent cylinder supported so as to be freely rotatable around a rotational axis thereof; a one-dimensional image pickup element disposed in the cylinder; and an optical system which is disposed in the cylinder and which forms an image of a subject coming into contact with an outer peripheral surface of the cylinder on the one-dimensional image pickup element; wherein the one-dimensional image pickup element includes a photoreceptive portion comprising photoelectric conversion elements arranged in a line on a silicon substrate, and the silicon substrate is mounted on a back surface of a film substrate having a surface facing the optical system so that the photoreceptive portion receives light emitted from the optical system; and wherein bonding pads for inputting/outputting electrical signals are mounted on a surface of the silicon substrate on which the photoreceptive portion is provided, bumps serving as terminals of wires are provided on the back surface of the film substrate, and the bonding pads and the bumps are joined to one another to fix the one-dimensional image pickup element to the film substrate.
