A banknote storage apparatus for easily removing banknotes stored therein includes a push bar, placed in an input port into which a banknote is inputted in a perpendicular direction, for providing stroke-operating toward a target storage part into which the banknote is determined to be stored; a driving motor for driving the stroke operation of the push bar; a pair of push plates for applying a pressure toward the input port in order to hold the banknotes perpendicularly stored according to the stroke operation of the push bar; and a detecting part for detecting an opening status of the door so that the driving motor is controlled to make the push bar move into a removing position for either one of the storage parts when detecting the opening status of the door.
