PROBLEM TO BE SOLVED: To provide a measuring device capable of suppressing power consumption in determination processing for determining whether or not there is a measurement object at a measurement position.SOLUTION: A measuring device includes: a spectral sensor including a light source for emitting a light to a measurement position, spectral means for dispersing a reflection light from an object at a measurement position or a transmission light that has transmitted the object at the measurement position according to wavelengths and light reception means that includes a plurality of pixels and receives the light dispersed by the spectral means, each of the plurality of pixels receiving a light including a predetermined wavelength； and control means for executing determination processing for controlling the spectral sensor and determining whether or not there is a measurement object at the measurement position, and measurement processing for, when it is determined that there is a measurement object at the measurement position in the determination processing, controlling the spectral sensor and measuring the measurement object. The control means causes emission intensity of the light source in the determination processing to be lower than the emission intensity of the light source in the measurement processing.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】測定位置に測定対象物があるかを判定する判定処理での消費電力を抑えることができる測定装置を提供する。【解決手段】測定装置は、測定位置に向けて光を射出する光源と、測定位置にある物体からの反射光、又は、測定位置にある物体を透過した透過光を波長に応じて分光する分光手段と、複数の画素を有し、分光手段が分光した光を受光する受光手段であって、複数の画素は、それぞれ所定の波長を含む光を受光する受光手段と、を含む分光センサと、分光センサを制御して測定位置に測定対象物があるかを判定する判定処理と、判定処理において測定位置に測定対象物があると判定すると、分光センサを制御して測定対象物を測定する測定処理と、を行う制御手段と、を備えており、制御手段は、判定処理における光源の発光強度を測定処理における光源の発光強度より低くする。【選択図】図１
