Claim Text:
1. An image sensor module comprising: a lens array in which a plurality of lenses are arranged in row form so that optical axes become parallel to one another; a first light blocking member which is arranged on one end side of the lens array, and in which a plurality of first through holes which allow light to pass through is provided in row form in the same direction as a main scanning direction that is the arrangement direction of the lenses; a second light blocking member which is arranged on the other end side of the lens array, and in which a plurality of second through holes which allow light to pass through is provided in row form in the same direction as the main scanning direction that is the arrangement direction of the lenses; and a linear-type image sensor which receives light emitted from the lenses of the lens array via the second through holes of the second light blocking member, wherein each of the first through holes and the second through holes include inner wall surfaces that intersect the main scanning direction having a plurality of first reflection surfaces and second reflection surfaces in a serrated shape, wherein the first reflection surfaces are parallel to the main scanning direction, and wherein the second reflection surfaces are disposed at an angle relative to the main scanning direction and relative to a sub-scanning direction that is orthogonal to the main scanning direction.
