Claim Text:
1. A check processing device comprising: an imaging element that reads the surface of a check exposed to reading light and outputs scanning information; a first light source that emits a first light with a different wavelength than ultraviolet light as the reading light; a second light source that emits an ultraviolet second light as the reading light; and a controller that controls driving the imaging element, first light source, and second light source, and includes a scanning information corrector that uses a first correction value to correct the scanning information accumulated while the second light is emitted in a first operating mode for reading the surface of the check by sequentially emitting the first light and then the second light, and uses a second correction value to correct the scanning information accumulated while the second light is emitted in a second operating mode for reading the surface of the check by emitting only the second light; wherein the first correction value is set based on a reference value previously set for the second light and an average of scanning information accumulated by the imaging element while the second light is emitted when the first light and then the second light are sequentially emitted within a specific time to the surface of a reference member and the surface of the reference member is imaged, and wherein the second correction value is set based on the reference value previously set for the second light, and an average of scanning information accumulated by the imaging element when the surface of the reference member is imaged by exposing the reference member to only the second light.
