A bill processing apparatus capable of inexpensively performing an authenticity judgment of a bill and a paper sheet on which a bar code is printed is provided. The bill processing apparatus has light emitting parts (80a, 81b) for irradiating an identification object passing through a traveling route with light; a light receiving part (81a) receiving light from the identification object that is irradiated by the light emitting parts (80a, 81b); a determining part (232) determining whether the identification object is a bill or a paper sheet on which a bar code is printed based on the light received by the light receiving part (81a); and a light emission control part controlling the light emission of the light emitting parts (80a, 81b). The light emission control part changes the lighting interval according to the object determined by the determining part (232).
