A paper sheet handling apparatus includes: a first stopper that is in contact with a first partition at a lower limit position of the first partition; and a pressing portion that is fixed to a second partition and raises and lowers the first partition integrally with the second partition using a frictional force generated by pressing a guide. The second partition descends integrally with the first partition, and after the first partition comes into contact with the first stopper, the second partition descends independently of the first partition against the frictional force to a position where the pressing portion faces the recessed portion that cancels the frictional force. The second partition, when ascending from the position where the pressing portion faces the recessed portion to a position where the pressing portion no longer faces the recessed portion, ascends integrally with the first partition due to the frictional force.
