A paper sheet insertion apparatus (for example, depositing and dispensing unit 20) includes an imaging unit (for example, camera 60) that takes an image of an interior of the paper sheet handling machine 10 to obtain image data and a control unit (for example, depositing and dispensing unit control unit 72) that is provided inside the machine body of the paper sheet handling machine 10 and outputs information on foreign material other than the paper sheet and information on a constituent member of the paper sheet insertion apparatus, based on the image data obtained by the imaging unit.
