A container changing system able to prevent deterioration in the working rate of substrate processing apparatuses and deterioration in the amount of production of semiconductor devices. A second mounting portion is arranged between a carrier of a container conveying unit and a first mounting portion of a substrate processing apparatus with respect to a lifting direction of a container. The second mounting portion is configured to freely advance and withdraw to/from a lifting path of the container. A container lifting unit is arranged between the carrier and the second mounting portion with respect to the lifting direction. In the container lifting unit, a base portion is configured to freely advance and withdraw to/from the lifting path, a second holder is provided below the base portion and can hold the container, and a second lifter is arranged between the base portion and the second holder and configured to lift up/down the second holder between the base portion and the first mounting portion when the second holder is located opposed to the first mounting portion. |
