A POSITIONING CONTROL METHOD OF A CONTACT IMAGE SENSOR HAVING A LIGHT RECEIVING ARRAY-SUBSTRATE, A PRODUCING METHOD OF THE CONTACT IMAGE SENSOR, AND THE CONTACT IMAGE SENSOR

摘要

A positioning control method of a contact image sensor with a light receiving array substrate, a method for manufacturing the contact image sensor, and the contact image sensor thereby are provided to control an electric signal on-line by adjusting the light receiving array substrate. A reference part with a uniform distribution of luminosity is loaded on an upper portion of a slit opening portion(23). A light is irradiated onto the reference part by using a light source. The light reflected from the reference part is received through the slit opening portion by using a light receiving element array. A sensor output is detected, wherein the sensor output is obtained by performing a photoelectric transformation on the light of the light receiving element array. Then, the position of the light receiving element array is properly adjusted to maximize the sensor output.
