ABSTRACT:
A thin-plate supporting container provided with supporting rib portions, each of which consists of multi-stage rib pieces, for supporting thin plates respectively on multiple stages at regular intervals. The supporting rib portions are provided on each of side walls of a casing of the container in parallel in such a way that each of the supporting rib portions provided on one of the side walls and a corresponding one of the supporting rib portions provided on the other of the side walls face each other and sandwich the thin plate. An opening portion of the thin-plate supporting container is an inlet/outlet port, through which the thin plate is loaded or unloaded from the container. Each of the supporting rib portions is composed of an inlet portion placed at the inlet/outlet-port-side thereof and a matching portion placed at an inner part thereof. Further, the opening between opposed side surfaces of each of the rib pieces placed at the inlet portions is set as being large so that the thin plate can be easily loaded and unloaded. The rib piece placed at the matching portion of each of the supporting rib portions is formed in such a manner that an angle of inclination of an upper side surface, on which the thin plate is put, of the rib piece placed at the matching portion thereof is smaller than an angle of inclination of an upper side surface of the rib piece placed at the inlet portion thereof so that the thin plate can be supported accurately in a horizontal position when the thin plate is put thereon and that the upper side surface of the rib piece placed at the matching portion thereof can come into point-contact or line-contact with an end portion of the thin plate.
