LIGHT-SHIELDING MEMBER, READING APPARATUS, AND IMAGE FORMING APPARATUS
A light-shielding member includes: plural light-shielding portions that extend in one direction and in which plural cylindrical through-holes which extend in an intersection direction intersecting the one direction and through which light passes are formed, the plural light-shielding portions being arranged in the one direction so that end portions of adjacent light-shielding portions overlap with each other in the intersection direction; and a fixing material that fixes the plural light-shielding portions to a housing in which an opening portion which opens in the intersection direction is formed so that the opening portion and the through-hole face each other in the intersection direction.
1 . A light-shielding member comprising:
a plurality of light-shielding portions that extend in one direction and in which a plurality of cylindrical through-holes which extend in an intersection direction intersecting the one direction and through which light passes are formed, the plurality of light-shielding portions being arranged in the one direction so that end portions of adjacent light-shielding portions overlap with each other in the intersection direction; and
a fixing material that fixes the plurality of light-shielding portions to a housing in which an opening portion which opens in the intersection direction is formed so that the opening portion and the through-hole face each other in the intersection direction.
2 . The light-shielding member according to claim 1 ,
wherein the end portions of the adjacent light-shielding portions have portions which overlap with each other in the intersection direction over an entire area in another intersection direction intersecting the one direction and the intersection direction.
3 . The light-shielding member according to claim 2 ,
wherein a first projection projecting in the one direction is formed at one side portion in the intersection direction at one end of the light-shielding portion in the one direction, and a second projection projecting in the one direction is formed at the other side portion in the intersection direction at the other end of the light-shielding portion in the one direction, and
the first projection of one light-shielding portion and the second projection of another light-shielding portion adjacent to the one light-shielding portion overlap with each other in the intersection direction.
4 . The light-shielding member according to claim 3 ,
wherein an intersection surface facing the intersection direction is formed on the second projection side of the first projection and on the first projection side of the second projection.
5 . The light-shielding member according to claim 2 ,
wherein a pair of first projections projecting in the one direction are formed at both side portions in the intersection direction at one end of the light-shielding portion in the one direction, and a second projection projecting in the one direction is formed at a central side portion in the intersection direction at the other end of the light-shielding portion in the one direction, and
the first projection of one light-shielding portion and the second projection of another light-shielding portion adjacent to the one light-shielding portion overlap with each other in the intersection direction.
6 . The light-shielding member according to claim 5 ,
wherein an intersection surface facing the intersection direction is formed on the first projection side of the second projection.
7 . A reading apparatus comprising:
the light-shielding member according to claim 1 ;
an optical member in which a plurality of lenses to which light passing through the through-hole of the light-shielding member is incident are formed; and
a substrate that includes an element which receives the light passing through the lens of the optical member.
8 . An image forming apparatus comprising:
the reading apparatus according to claim 7 ; and
a transfer apparatus that transfers an image read by the reading apparatus to a recording medium.
