Image reading device comprising a lens array including first lens bodies and second lens bodies, a light receiver and light blocking plates that are between the light receiver and second lens bodies, the thickness of the light blocking plates equal to or greater than the second lens bodies thickness

Abstract

An image reading device () includes a lens array (), a light receiver (), and at least one light blocking member. The lens array () includes first lens bodies arranged in a line in a main scanning direction with predetermined spacing therebetween to converge light from a reading target. The light receiver () receives light converged by each first lens body. The at least one light blocking member is disposed between the light receiver () and an end of the lens array () proximate to the reading target at at least one position corresponding to the predetermined spacing in the main scanning direction. The at least one light blocking member blocks light from the reading target propagating between the first lens bodies, and each of the at least one light blocking member separates optical paths of light converged by ones of the first lens bodies adjacent to each other.
