Abstract

Provided is a structural body, formed in a plate-like shape and positioned with respect to an assembly jig including a positioning pin and supporting a first surface of the structural body, including a positioning hole formed through an end portion, a positioning protrusion being inserted into the positioning hole; and a pair of first position detection areas formed on a second surface of the end portion through which the positioning hole is formed. The positioning hole is formed apart from an axis line connecting the pair of first position detection areas.

First claim

The invention claimed is:

1. A structural body formed in a plate-like shape and an elongated shape having a short side direction and a long side direction and positioned with respect to a positioning device, the positioning device including a pair of positioning protrusions and supporting a first surface of the structural body, the structural body comprising:
a pair of positioning holes formed through both end portion in the long side direction, the pair of positioning protrusions being inserted into the pair of positioning holes;
a pair of first position detection areas formed on a second surface of a first end portion through which a first hole of the pair of positioning holes is formed; and
a pair of second position detection areas formed on the second surface of a second end portion through which a second hole of the pair of positioning holes is formed,
wherein the first hole of the pair of positioning holes is formed apart from an axis line connecting the pair of first position detection areas,
the second hole of the pair of positioning holes is formed apart from an axis line connecting the pair of second position detection areas,
a pair of protruding sections protruding outwardly in the long side direction are formed at the both end portions, the length of the pair of protruding sections in the short side direction being shorter than the length of the structural body in the short side direction,
the first hole of the pair of positioning holes and the pair of first position detection areas are formed at a first section of the protruding sections,
the second hole of the pair of positioning holes and the pair of second position detection areas are formed at a second section of the protruding sections,
the second surface of the first section of the pair of protruding sections includes a first region processed to increase a difference in luminance from the pair of first position detection areas, the first region being a region where the pair of first positioning detection areas are not formed and being subjected to a surface treatment in order to reduce specularity of surface reflecting external light, and
the second surface of the second section of the pair of protruding sections includes a second region processed to increase a difference in luminance from the pair of second position detection areas, the second region being a region where the pair of second positioning detection areas are not formed and being subjected to a surface treatment in order to reduce specularity of surface reflecting external light.

2. The structural body according to claim 1 , wherein the pair of first position detection areas are through-holes each penetrating the first surface and the second surface.
