Disclosed is a bill recycle machine, in which a separation part for separating bills from each other and a push plate are installed at the same level as a bill receiving space, and an elevation plate is removed, so that a simple structure and small volume thereof can be achieve. The bill recycle machine includes: a front plate forming a wall surface of a front side of a bill receiving space formed at a lower part of a shutter, the front plate rotating about a hinge shaft of an upper part of the front plate; a push plate forming a first bill receiving space between the push plate and the front plate; a stack plate installed at an opposite side of the first bill receiving space, based on the push plate, so as to support bills stacked through a stack wheel; a transfer plate forming a second bill receiving space between the transfer plate and the stack plate; and a pickup roller installed at a position allowing the pickup roller to make contact with bills stacked in the first bill receiving space when the push plate moves frontward.
