Abstract
An original sheet circulation apparatus of a copying machine comprising an original sheet circulation route formed by two guide plates, which is capable of circulating one original sheet in repetition when multiple copies are made from one original, so as to connect an original sheet inlet portion and an original sheet outlet portion of the copying machine. When a desired number of copies are made from each original sheet, each original is held in the original sheet circulation route by a stopper member or stacked on an original sheet stacking portion disposed on the original sheet circulation route by a sheet transportation change-over means. The original sheet circulation apparatus is detachable from the copying machine.
