A paper sheet handling apparatus (banknote handling apparatus 100) includes: a housing 12; a transport path forming member 711 disposed inside the housing and configured to form a transport path that transports paper sheets while sandwiching each paper sheet in a direction of the thickness of the paper sheet; and a handing unit (non-bundling stacker module 54) disposed at a predetermined position inside the housing. When jamming of paper sheets occurs in the middle of the transport path, the transport path forming member is displaced so as to open the transport path, in a state where the inside of the housing is opened by an opening and closing unit being opened. The handling unit disposed adjacent to the transport path is movable from the predetermined position so as to form a space that allows the transport path forming member to be displaced.
