The edges include convex portions and convex portions for connecting the sensor substrates. Farthest tips of the sensor chips are positioned inside of farthest edges of the convex portions and inside of farthest edges of the convex portions in the longitudinal direction.
This image sensor unit has: catoptric light guide bodies (16) for irradiating a banknote (S) with light from catoptric light sources (15) via catoptric light exit faces (16b); a transmitted light guide body (23) for irradiating the banknote (S) with light from a transmitted light source (24) via a transmitted light exit face (23b); a rod lens array (18) for forming an image of the light reflected off the banknote (S) and/or the light that has transmitted through the banknote (S); light-receiving elements (19) for receiving the light collected by the rod lens array (18); and a frame (13) that has a housing section (17) capable of housing the catoptric light guide bodies (16). Light-shielding sections (25), which protrude from the catoptric light exit faces (16b) of the catoptric light guide bodies (16) toward the optical axis (Z) side of the rod lens array (18), are formed on portions of the housing section (17). The light-shielding sections (25) have positioning reference faces (26) for the catoptric light guide bodies (16). The impact of stray light can be reduced, so the accuracy of a read image is improved.
An image sensor unit includes: a light source including a light-emitting surface that emits light; a substantially rod-shaped light guide including a light emitter that linearizes the light from the light source and irradiates a sheet; an image sensor that receives light from the sheet and converts the light into an electric signal; a light condenser focusing the light from the sheet onto the image sensor; a circuit board on which the light source and the image sensor are mounted; and a frame accommodating the light guide, the light condenser and the circuit board. The light condenser and the light emitter of the light guide are disposed substantially parallel to each other. The center line of the light-emitting surface of the light source is disposed nearer the optical axis of the light condenser than the center line of the light emitter.
An image sensor unit includes: a light source including a light emitting element on a light emitting surface; a light guide that causes light from the light source to be incident on a light incident surface facing to the light emitting surface, ejects the light from a light ejecting surface and illuminates a document; a rod lens array that images reflected light from the document; a sensor substrate on which a photoelectric conversion element is mounted, the photoelectric conversion element converting the reflected light imaged by the rod lens array into an electric signal; and a frame that supports the light source, the light guide, the rod lens array and the sensor substrate, wherein positioning sections are provided on an opposite side of the light emitting surface of the light source and at a part of the frame which is disposed at the opposite side of the light emitting surface.

In a so‑called sky shot, in which reading is performed with a platen cover (32) open, a white reference value generated from a white reference element (40) is compared with the output signal of the read image. During the process of reading an original (34), an additional reading operation for each scan line will be performed with the light source unit in an image sensor unit (33) turned off only if a value that is greater than or equal to the white reference value is present in the output signal of the read image.

The imaging element (5) connects cut sections of a plurality of rod lens arrays (5) each of which has at least one end section in the longitudinal direction cut, so that a prescribed readout width can be obtained. The frame (8) has a holding section (13) for holding the rod lens array (5), and the holding section (13) has wide widths for the cut section of the rod lens array (5) and/or the bottom surface (13B) where the connecting section is positioned.
Photoelectric conversion elements (2k) are fixed on a circuit board (1) by a thermosetting first adhesive agent (3k) and a thermosetting second adhesive agent (4k). The photoelectric conversion elements (2k) in the regions on which the first adhesive agent (3k) is provided have a dimension of W1 in an array direction. The photoelectric conversion elements (2k) in the regions on which the second adhesive agent (4k) is provided have a dimension of W2 in the array direction. The dimension of the photoelectric conversion elements (2k) in the array direction (longitudinal direction) is W. Among the values of W, W1, and W2, the relationship W > W1 + W2 is satisfied. Accordingly, the relationship W > W1 is also satisfied.

In a substrate (1), a recessed portion (4k) located under the central portion of a photoelectric conversion element (2k) exists. The photoelectric conversion element (2k) is laid across the edge of the recessed portion (4k). An adhesive (3k) is applied into the recessed portion (4k), and the photoelectric conversion element (2k) is bonded to the circuit substrate (1) by the adhesive (3k).
There is a possibility that an optical line from a manuscript to an image sensor array and an optical axis of a rod lens array do not correspond to each other in a conventional image sensor unit. The inner wall of a lens housing chamber (14) forms a reference surface (23) for adhering and fixing itself to a second side plate (25a) of a rod lens array (9).
