Abstract:
Light-shielding layers (11a, 11b) are adhered to the lower surface of a glass plate (4), spaced apart from each other and defining a slit having a width of L. An array (5) of rod lenses is located below the glass plate (4), such that the optical axes of the lenses pass through the slit. The lower surface of the glass plate (4) is generally covered, and exposed via the slit only. Hence, the leakage of lights reflected from points near a reading position (P) into each photoelectric conversion element (7) is minimized, whereby the element (7) outputs a pixel signal faithfully representing that part of the image which is located at the reading position (P).
Abstract:
An image sensor has a supporting member for integrally supporting a reading system including illuminating means for illuminating an original document, a photoelectrically converting means and imaging means for imaging light reflected by the surface of the original document onto the photoelectrically converting means, and has a member disposed on the side surface of the supporting member. The image sensor has two or more substantially independent spaces formed in the supporting member. The illuminating means, the imaging means and the photoelectrically converting means are accommodated in one of the spaces.
