PROBLEM TO BE SOLVED: To achieve both compaction of the size in the sub-scanning direction and up-sizing of the coating area of a sealing material and a white reference.SOLUTION: Image sensor units 1 are used by facing them each other so that both sides of a paper S to be read can be read, and each of them includes: a light source module 17 for irradiating light toward the paper S; a condenser 15 for condensing the light from the paper S; an image sensor 161 for detecting the light condensed by the condenser 15; a frame 11 for housing the light source module 17, the condenser 15. and the image sensor 161; and a cover member 12 covering the frame 11. The cover member 12 is bonded to the frame 11 by an adhesive material 2, and at least a portion of the adhesive material 2 is provided to be located on the optical axis Lof the condenser 15 in the other opposite image sensor unit 1. |
