Abstract:
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.

PROBLEM TO BE SOLVED: To provide an image reading device which eliminates the need for additional components for coupling and transparency of components and couples a fixing member to a support member assuming that high accuracy positioning adjustment is conducted when the fixing member fixed to a substrate member is coupled to the support member supporting an optical system.SOLUTION: An imaging reading device 600 includes: LEDs 2a, 2b; a lens 55; a substrate member 53 having a photoelectric conversion element 71; a fixing member 15 having a bending protrusion part 15X1 protruding in a direction perpendicular to a sub-scanning direction Z of the lens 55 and fixed to the substrate member 53; an optical holding member 56 supporting the lens 55; and a UV adhesive Q joining the fixing member 15 to the optical holding member 56. An adhesive application part 60 of the UV adhesive Q adhering the fixing member 15 and the optical holding member 56 is disposed so as to protrude in a state that the adhesive application part 60 has a gap K1 between itself and the bending protrusion part 15X1 and a peripheral part 56R and is not in contact with those parts. The UV adhesive Q is applied to the gap K.
Abstract:
An optical component structure includes an elongate optical component, a support member to which the optical component is fixed, and an adhesive for bonding the optical component to the support member. The optical component is provided with a contacting portion and a bonding portion different in position from the contacting portion. The contacting portion is brought into direct contact with the support member in a direction perpendicular to the longitudinal direction of the optical component. The adhesive is applied to the bonding portion, but not to the contacting portion. Examples of the optical component include a linear light source unit and a lens unit used in an image sensor module.
