A light detection sensorcomprises a light sourcefor radiating light to a detection object T and a light receivercomprising a plurality of detectors for detecting intensity of light from the detection object T. The plurality of detectors comprises at least, a first detectorfor detecting intensity of light of a first wavelength band, and a second detectorfor detecting intensity of light of a second wavelength band different from the first wavelength band. Sensitivity of the first detectorto the light of the first wavelength band is lower than sensitivity of the second detectorto the light of the second wavelength band. A light receiving area of the first detectoris larger than a light receiving area of the second detector

Light detection sensor, light detection device, and paper sheets processing device

A light detection sensor includes a light source that irradiates a detection target with light, a rod lens that collects emitted light from the detection target, a first light receiving element that detects the emitted light that has passed through the rod lens, and a second light receiving element that detects the emitted light that has passed through the rod lens, at a position different from a position at which the first light receiving element detects the light.

Light detection sensor, light detection device, sheet processing device, and light detection method

An aim is to reduce the size of an optical sensor which detects radiated light such as phosphorescence radiated from a detection target excited by exciting light, and to increase a radiated light receiving surface of the optical sensor. An optical sensor is configured to be provided with: a light source which irradiates excitation light; a light detector which detects radiation light emitted from a detection target excited by the excitation light; and a single light guide unit which guides the excitation light to the detection target and guides the radiation light to the light detector.

Optical sensor, light detection apparatus, sheet processing apparatus, light detection method, and phosphorescence detection apparatus

A paper sheet recognition apparatus () that recognizes a paper sheet based on an optical spectrum acquired from the paper sheet includes, a light source unit () including light sources arranged corresponding to partial areas on the paper sheet, a reading unit () having a light receiving surface to receive reflected lights from the partial areas, a sensor unit () that acquires an optical spectrum of light received by the light receiving surface, a memory () that stores an optical spectrum measurement condition, and a light-source control unit () that controls the light source unit () based on the optical spectrum measurement condition. The optical spectrum measurement condition includes information for identifying at least one light source corresponding to the predetermined partial area, information for identifying a timing for turning on the identified light source, and information for identifying a timing for turning off the light source.

Paper sheet recognition apparatus and paper sheet recognition method

A paper sheet recognition apparatus that recognizes a paper sheet based on optical characteristics of the paper sheet is proposed. The paper sheet recognition apparatus includes at least one light source that emits a light toward the paper sheet; a light-guiding member that receives any of reflected lights reflected from plural regions on the paper sheet and transmitted lights that have passed through plural regions on the paper sheet because of emission of the light on the paper sheet from the light source, condenses the received lights, and outputs the condensed light from a light outputting section; an optical processing unit that generates spectral distribution from the condensed light output from the light outputting section of the light-guiding member; and a recognition processing unit that recognizes the paper sheet based on a feature of the spectral distribution generated by the optical processing unit.
