Abstract: In order to efficiently acquire an optical characteristic from partial areas on the paper sheet, a paper sheet recognition apparatus (1) that recognizes a paper sheet by using an optical spectrum acquired from the paper sheet on a transport path (60) includes, a light source unit (31) including light sources arranged corresponding to the partial areas on the paper sheet, a reading unit (32) having a light receiving surface to receive reflected lights from the partial areas, a sensor unit (34) that acquires an optical spectrum from light received by the light receiving surface, a memory (80) that stores an optical spectrum measurement condition for acquiring an optical spectrum from a predetermined partial area on the paper sheet. The optical spectrum measurement condition includes information for identifying at least one light source corresponding to the predetermined partial area among the light sources of the light source unit (31), information for identifying a timing for turning on the identified light source, and information for identifying a timing for turning off the light source turned on at the timing for turning on; and a light-source control unit (72) that controls the light source unit (31) based on the optical spectrum measurement condition.
