PROBLEM TO BE SOLVED: To reduce the size of a color measuring device.SOLUTION: A color measuring device time-divides an emission of a different wavelength from an LED 120 (light source) and irradiates a tongue TG (color measurement object) with the time-divided emission, and detects the intensity of light reflected on the color measurement object with a photodetector 118.SELECTED DRAWING: Figure 2【課題】測色装置の小型化を図る。【解決手段】LED120(光源)から異なる波長の出射を時間分割して舌TG(測色対象)に照射し、測色対象で反射された反射光の光量を光検出器118で検出する。【選択図】図2
