PROBLEM TO BE SOLVED: To provide an erecting equal magnification lens array unit that prevents specific crosstalk of an erecting equal magnification lens array and suppresses occurrence of flare noise to improve optical performance, and an image reading device using the erecting equal magnification lens array unit.SOLUTION: An erecting equal magnification lens array unit laminates, in an incident direction of light 6 from an object surface A side to an imaging surface B, a first lens array 1 where a plurality of first lenses 11 are arranged in a direction perpendicular to the optical axis of the first lenses 11, and a second lens array 2 where a plurality of second lenses 21 whose optical axis is coincidence with the optical axis of each of the first lenses 11 are arranged, in this order. The first lens array 1 and the second lens array 2 are opposite to each other so as to form an erecting equal magnification optical system with the first lenses 1 and the second lenses 2 whose optical axes are overlapped with each other. On the object surface A side of the first lens array 1, a view angle adjustment film 5 is provided. |
