1. A substrate conveying container opening/closing device for bringing a periphery of a lid openably closing a front surface of a substrate conveying container into contact with a periphery of a first opening formed at a first surface side of a wall, and for removing the lid through a second opening
1. A substrate conveying container opening/closing device for bringing a periphery of a lid openably closing a front surface of a substrate conveying container into contact with a periphery of a first opening formed at a first surface side of a wall, and for removing the lid through a second opening formed to be inclined upward with respect to a vertical plane and formed on a substrate transfer area which is at a second surface side of the wall, the device comprising: an elevator carriage installed at the substrate transfer area, and configured to be moved up and down by an elevator mechanism;a cover member configured to open and close the second opening, to be supported by the elevator carriage, and to be provided with a peripheral edge portion making contact with a periphery of the second opening to close the second opening;a seal member configured to seal a gap between the cover member and the periphery of the second opening;a lid detaching/attaching mechanism installed at the cover member, and configured to detach and attach the lid of the substrate conveying container while the second opening is closed by the cover member;a guide unit installed at the elevator carriage, and configured to guide the cover member upward and to restrain a position of the cover member, in order for the cover member to advance from a retracting position toward the wall with respect to the elevator carriage;a guideway installed at the wall to extend in a direction perpendicular to a seal surface of the periphery of the second opening; anda rotating body installed at the cover member, and configured to be rotatable about a laterally-extending axis and parallel to an opening surface of the second opening, and configured to make contact with the guideway from above and to roll downward along the guideway as the elevator carriage is moved downward,wherein the cover member is configured to lie in a retracting position when the elevator carriage is in an upper position, configured to advance from the retracting position by a rolling movement of the rotating body and the guiding action of the guide unit as the elevator carriage is moved downward, and configured to close the second opening in a posture opposing the second opening. 2. The device of claim 1, wherein the elevator carriage has a first support surface formed along a direction perpendicular to an advancing/retracting direction of the cover member with respect to the elevator carriage, and wherein the cover member has a second support surface formed to face the first support surface, and includes a biasing mechanism installed between the first support surface and the second support surface opposing each other to bias the cover member away from the wall and toward the substrate transfer area. 3. The device of claim 2, further comprising: a stopper mechanism composed of an elastic body, and installed between the first support surface and the second support surface opposing each other to restrain a collision between the elevator carriage and the cover member. 4. A substrate conveying container opening/closing device for bringing a periphery of a lid openably closing a front surface of a substrate conveying container into contact with a periphery of a first opening formed at a first surface side of a wall, and for removing the lid through a second opening formed to be inclined downward with respect to a vertical plane and formed on a substrate transfer area which is at a second surface side of the wall, the device comprising: an elevator carriage installed at the substrate transfer area, and configured to be moved up and down by an elevator mechanism;a cover member configured to open and close the second opening, to be supported by the elevator carriage, and to be provided with a peripheral edge portion making contact with a periphery of the second opening to close the second opening;a seal member configured to seal a gap between the cover member and the periphery of the second opening;a lid detaching/attaching mechanism installed at the cover member, and configured to detach and attach the lid of the substrate conveying container while the second opening is closed by the cover member;a guide unit installed at the elevator carriage, and configured to guide the cover member downward, and to restrain a position of the cover member, in order for the cover member to advance from a retracting position toward the wall with respect to the elevator carriage;a guideway installed at the wall to extend in a direction perpendicular to a seal surface of the periphery of the second opening;a rotating body installed at the cover member, configured to be rotatable about a laterally-extending axis and parallel to an opening surface of the second opening, and configured to make contact with the guideway from below and to roll upward along the guideway as the elevator carriage is moved upward; andthe cover member configured to lie in a retracting position by a bias force of a biasing mechanism when the elevator carriage is in a lower position, configured to advance from the retracting position against the bias force of the biasing mechanism by a rolling movement of the rotating body and the guiding action of the guide unit as the elevator carriage is moved upward, and configured to close the second opening in a posture opposing the second opening,wherein the biasing mechanism biases the cover member toward the substrate transfer area with respect to the elevator carriage. 5. A lid opening/closing device for opening and closing, from a second surface side of an opening communicating a first surface side and the second surface side of a wall, a lid of a substrate transfer container installed at the first surface side or a lid hermetically closing the opening from the second surface side, the device comprising: a moving carriage installed at the second surface side of the wall, and configured to be moved by a moving mechanism between a first side and a second side of a shaft extending parallel along the wall;a seal surface formed in a periphery of the opening at the second surface side, and configured to be inclined toward the first side of the shaft with respect to a direction perpendicular to the wall;a cover member configured to open and close the opening, to be supported by the moving carriage, and to be provided with a peripheral edge portion making contact with the seal surface at the second surface side to close the opening;a seal member configured to seal a gap between the cover member and the seal surface;a lid detaching/attaching mechanism installed at the cover member, and configured to detach and attach the lid while the opening is closed by the cover member;a guide unit installed at the moving carriage, and configured to guide the cover member along a direction between a direction perpendicular to the wall and a direction toward the first side, and to restrain a position of the cover member, in order for the cover member to advance from a retracting position toward the wall with respect to the moving carriage;a guideway installed at the wall to extend in a direction perpendicular to the seal surface;a rotating body installed at the cover member, configured to be rotatable about an axis intersecting the shaft and parallel to the seal surface, and configured to make contact with the guideway and to roll along the guideway as the moving carriage is moved toward the first side; andthe cover member configured to lie in a retracting position when the moving carriage is in the first side position, to advance from the retracting position by a rolling movement of the rotating body and the guiding action of the guide unit as the moving carriage is moved toward the first side, and to close the opening in a posture opposing the seal surface,wherein a biasing mechanism biases the cover member toward the substrate transfer area with respect to the elevator carriage. 6. A semiconductor manufacturing apparatus, comprising: a support table configured to place a substrate conveying container;a processing unit configured to perform processing with respect to a substrate;a substrate transfer mechanism configured to deliver the substrate between the substrate conveying container placed on the support table and the processing unit; andthe opening/closing device of claim 1 configured to open and close a lid of the substrate conveying container placed on the support table or a lid installed between the processing unit and the substrate transfer mechanism. 7.
