Abstract:
A first lens array unit includes a first lens array plate and a second lens array plate in which a plurality of lenses are provided in the main scanning direction, and a first light shielding member piece and a second light shielding member piece provided with a plurality of through holes corresponding to the lenses. The first lens array plate, the second lens array plate, the first light shielding member piece, and the second light shielding member piece are formed as one piece. The lens array is built by bending joints joining the lens array plates and the light shielding member pieces such that the lens is located to directly face the corresponding through hole.
