An object of the present invention is to provide a more compact processing apparatus than previously available. Provided is a processing apparatus for unfurling or folding a processing subject (T), including a pair of retaining devices (310A, 310B) capable of retaining the processing subject (T), a carrying device (402) capable of carrying the processing subject (T) such that a part of the processing subject (T) hangs down therefrom while the processing subject (T) is retained by at least one of the pair of retaining devices (310A, 310B), and a control device that controls movement of the retaining devices (310A, 310B) and the carrying device (402), wherein the control device rotates the carrying device (402) in a condition where the retained processing subject (T) hangs down from the carrying device (402).
