A stack unit of a recycle box is provided to stably receive and eject bills by adjusting the inner stack space according to the kind of bills, which are deposited in an ATM(Automatic Teller Machine). A stack body(110) has an open front surface and contains bills therein. The stack body is installed in a case unit of a recycle box. A liftable push plate(120) is installed in the stack body. Bills are stacked on the push plate. A plate driver includes a driving shaft, a roller bearing(20), a pinion gear(30), a support shaft, a support bearing(50), and a driving motor(60). The driving shaft is elongated toward a guide groove, which is formed to be normal to an inner wall of the stack body. The roller bearing is coupled with both ends of the driving shaft and slid along the guide groove. The pinion gear is engaged with a rack gear, which is formed to be normal to the inner wall of the stack body. The support shaft is protruded toward the guide groove from both sides of the push plate and implemented at the upper or lower portion of the driving shaft. The support bearing is coupled with both sides of the support shaft and slid along the guide groove. The driving motor is attached to the bottom of the push plate and delivers a rotational force to the driving shaft.
