A bill ejector of an automatic teller machine is provided to accurately control the operation state and range of respective components by adjusting the rotation angle and direction of a cam rotation assembly. A storage(110) stores paper media. A stack unit(130) stacks the paper media and includes a stack support, which is moved up and down along a predetermined path, and a guide protrusion, which is formed at a side portion of the stack support mount. A bill ejecting unit(170) supplies the stack of the paper media from the stack unit to customers. A first transfer unit(120) transfers the paper media from the storage to the stack unit. A second transfer unit transfers the paper media from the stack unit to the bill ejecting unit. A stack transfer unit includes an elevation driver and a cam rotation assembly. A guide rail is apart from the rotation center by a distance, which is varied according to the rotation angle of the cam rotation assembly. The guide protrusion is coupled with the guide rail and moved up and down, so that the stack support mount is lifted. |
