Abstract

Provided are a sheet recognition unit and a sheet recognition method capable of simultaneously acquiring visible range data and infrared range data without using a filter configuration that is difficult to manufacture. A sheet recognition unit includes a light source capable of emitting light having a specific wavelength to a sheet to be recognized, a light receiving unit that receives light coming from the sheet to be recognized, based on the light from the light source and outputs a light detection signal, and a recognition unit that recognizes the sheet to be recognized, using the light detection signal output from the light receiving unit. The light receiving unit includes a first light receiving element including a color filter that transmits blue light and infrared light, a second light receiving element including a color filter that transmits green light and infrared light, a third light receiving element including a color filter that transmits red light and infrared light, and a fourth light receiving element including a color filter that transmits only one of blue light, green light, red light, or infrared light.
