    Abstract: An image scanner is provided which is capable of preventing decrease in image contrast and improving the reading accuracy and quality of color images to a greater extent. An image scanner includes a unit case having an opening formed on one end surface thereof; light-source lamps and light-source lenses which are disposed in the inner portion of the opening of the unit case in such a manner as to face the opening; holding plates which are disposed in the inner portion of the opening of the unit case and which have formed therein slits for extending the terminals of the light-source lamps to the inside of the unit case; and CCD sensors, disposed at the end portion of the inside of the unit case on the side opposite to the opening, for reading an image of the original document by receiving, via a lens unit, light which is radiated onto a given original document placed near the opening from the light-source lamps via the light-source lenses and reflected from this original document.

    Abstract: An image sensor (100) comprises a lens (4), a sensor (6) and a first casing (1). The lens (4) is configured to focus light irradiated toward an object to be read (30) from a direction tilted relative to the X-Z plane, and reflected by the object to be read (30). The sensor (6) is configured to receive the light focused by the lens (4). The first casing (1) is configured to contain or retain the lens (4) and the sensor (6) and to have, in a surface (1j) extending along a main scanning direction, a tilted portion having a length in a sub-scanning direction that decreases toward the object to be read (30).
