PROBLEM TO BE SOLVED: To suppress erroneous detection or detection omission about an increase or decrease in a detection object due to not only disturbance light made incident to light reception means but also a factor other than the disturbance light.SOLUTION: An object detection device configured to, on the basis of an illumination time received light amount y (x, ta) received by light reception means when a light source emits light source light, detect a detection object within the illumination range of the light source light executes detection processing for, by using an illumination time change amount ey (x, ta) indicating the time change of the illumination time received light amount and a non-illumination time change amount ed (x, tb) indicating the time change of a non-illumination time received light amount received by the light reception means when the light source does not emit the light source light, determining whether or not predetermined conditions S4, S5, S8, S9 for detecting an increase or decrease in the detection object within the illumination range are satisfied (S11).SELECTED DRAWING: Figure 15

    【課題】受光手段に入射する外乱光だけでなく、外乱光以外の要因による検出対象物の増加や減少についての誤検出や検出漏れをも抑制することを課題とする。【解決手段】光源が光源光を照射している時に受光手段により受光される照明時受光量y(x,ta)に基づいて該光源光の照明範囲内における検出対象物を検出する物体検出装置において、前記照明時受光量の時間変化を示す照明時変化量ey(x,ta)と、前記光源が光源光を照射していない間に前記受光手段により受光される非照明時受光量の時間変化を示す非照明時変化量ed(x,tb)とを用いて、前記照明範囲内における検出対象物が増加した又は減少したことを検出するための所定の条件S4,S5,S8,S9を満たすか否かを判断する検出処理を実行する(S11)。【選択図】図15
