1. A substrate storing container, comprising:
a container main body having a tubular wall portion having an opening circumferential portion provided at one end portion and the other end portion being closed, the opening circumferential portion having a container main body opening portion formed therein, the wall portion having an inner face forming a substrate storing space capable of storing a plurality of substrates and communicating with the container main body opening portion;
a lid body removably attached to the container main body opening portion and capable of closing the container main body opening portion;
a lid body side substrate support portion disposed on a part of the lid body that faces the substrate storing space and capable of supporting edge portions of the plurality of substrates when the container main body opening portion is closed by the lid body; and
a back side substrate support portion disposed so as to form a pair with the lid body side substrate support portion in the substrate storing space, capable of supporting edge portions of the plurality of substrates, and supporting the plurality of substrates in a state in which the plurality of substrates are arranged in parallel, in cooperation with the lid body side substrate support portion when the container main body opening portion is closed by the lid body,
wherein the back side substrate support portion comprises a first abutting portion having a first abutting face capable of abutting with an end edge of a front side of one of the plurality of substrates and a second abutting portion having a second abutting face capable of abutting with an end edge of a back side of the one of the plurality of substrates, the second abutting face being connected to the first abutting face,
wherein the plurality of substrates slide on a plurality of the second abutting faces when a state in which the container main body opening portion is not closed by the lid body is changed to a state in which the container main body opening portion is closed by the lid body and when the state in which the container main body opening portion is closed by the lid body is changed to the state in which the container main body opening portion is not closed by the lid body,
wherein when the state in which the container main body opening portion is closed by the lid body is changed to the state in which the container main body opening portion is not closed by the lid body, the end edges of all of the plurality of substrates are caused to automatically slide on the plurality of the second abutting faces so that all of the plurality of substrates move to, and become placed on, lower abutting faces connected to the plurality of the second abutting faces, thereby allowing the plurality of substrates to be automatically removed by a substrate transfer machine,
wherein the back side substrate support portion comprises an alloy resin consisting of a polycarbonate resin and a polybutylene terephthalate resin, and a mass of the polybutylene terephthalate resin is greater than that of the polycarbonate resin, and
wherein a material constituting the back side substrate support portion comprises the polybutylene terephthalate resin in an amount of 51% by mass or more with respect to a mass of the alloy resin.
