Abstract: There is a problem that the contact-type image sensor, for adoption in an image input/output apparatus to input/output the image of a large-sized document, such as A0 or A1 size, is weak in lengthwise rigidity and readily deflected at its lengthwise center by its own weight. Accordingly, by attaching a deformation rectifier to the image sensor in a lengthwise direction thereof, the contact type image sensor is reinforced in lengthwise rigidity. The deformation rectifier reinforces the rigidity of the contact type image sensor, thereby preventing the contact type image sensor from deflecting vertically relative to its lengthwise direction and keeping constant the focal length between the surface of the document to be read and the sensor IC.

The peak hold circuit holds the peak value of the first voltage signal. The comparator outputs a pulse on the basis of the first and second voltage signals. The threshold current setting circuit draws out a threshold current.

Abstract: Light-shielding layers are adhered to the lower surface of a glass plate, spaced apart from each other and defining a slit having a width of L. An array of rod lenses is located below the glass plate, such that the optical axes of the lenses pass through the slit. The lower surface of the glass plate is generally covered, and exposed via the slit only. Hence, the leakage of lights reflected from points near a reading position into each photoelectric conversion element is minimized, whereby the element outputs a pixel signal faithfully representing that part of the image which is located at the reading position.
