To surely detect a residual bill or foreign object in a bill input reception port.

An ATM 10 is provided with bill detection sensors 30, 40 for detecting a residual bill 34 as well as a hand camera 19 capable of imaging the inside of a bill input reception port 13. If the bill detection sensors 30, 40 cannot detect the residual bill 34, based on the image data imaged by the hand camera 19, a camera image processing unit 20b recognizes the presence or absence of the bill 34 or a foreign object, based on the result of which, a determination unit 20a determines whether the bill 34 or foreign object is present or not. Therefore, the residual bill 34 can be surely detected. Furthermore, if a hand sensor 41 for detecting the hand of a user cannot detect the insertion of hand, based on the image data imaged by the hand camera 19, the insertion of hand can be surely detected.
