## Abstract

A thin-plate supporting container provided with supporting rib portions, each of which consists of multi-stage ribs, for supporting thin plates respectively on multiple stages at regular intervals. The ribs are provided in parallel on each of opposing side walls of the container casing in such a way that the supporting rib portions cooperate to hold the thin plates. An open end of the thin-plate supporting container serves as an inlet/outlet port, through which the thin plates are loaded and unloaded from the container. Each of the supporting rib portions is composed of an inlet portion adjacent the inlet/outlet-port and a support portion interior thereof. Further, the opening between opposed side surfaces of adjacent ribs is set to be sufficiently large that the thin plate can be easily loaded and unloaded. The rib plate support portion is formed in such a manner that the angle of inclination of its upper side surface, on which the thin plate rests, is smaller than an angle of inclination of the upper side surface of the rib inlet portion so that the thin plate can be supported accurately in a horizontal position and so that the upper surface of the rib support portion provides point-contact or line-contact with an end portion of the thin plate.

## Claims

### Claim 1

A thin-plate supporting container comprising:
a casing having first and second opposed side walls, an open end serving as an inlet/outlet port, through which thin plates are load and unloaded from the container, and a rear end; and
first and second pluralities of spaced parallel ribs extending along interior surfaces of said first and second opposed side walls, respectively, the ribs of said first plurality being aligned with corresponding ribs of said second plurality, along a line perpendicular to said opposed side walls, to define plural stages for holding the thin plates, each of said ribs including a plate support portion and a raised portion which together define an upper surface for each rib with a step separating said plate support portion from said raised portion and forming a shoulder for abutting the edge of a thin-plate for holding the thin-plate resting on said plate support portion in a fixed position within the container.

### Claim 2 (depends on 1)

A container according to claim 1 wherein said shoulder is curved in an arc to mate with a circular thin plate.

### Claim 3 (depends on 1)

A container according to claim 1 wherein each rib has said raised portion located between said open end and said plate support portion, with said shoulder transverse the width of the rib to prevent the thin-plate from shifting toward said open end.
