1. A conveying system which conveys a workpiece via an opening of a wall disposed between a set area and a machining area, the conveying system comprising:
a base;
a guide member provided on the base;
a first moving element in which a movement between the set area and the machining area is guided by the guide member;
a second moving element which has a workpiece mounted thereon, and is disposed on the first moving element;
a support mechanism which supports the second moving element with respect to the first moving element, and has a spring disposed between the first moving element and the second moving element and which supports a weight of at least a part of the second moving element; and
a fixing mechanism which fixes the second moving element to the base in the machining area, and has a first mode in which the spring is elastically deformed by applying a predetermined force in addition to the weight of the second moving element and the base and the second moving element are mechanically engaged with each other, and a second mode in which the predetermined force on the spring is released and a mechanical engagement between the base and the second moving element is released.
