To provide an article inspection device with which it is possible to guarantee required accuracy of measurement while reliably preventing degradation of yield due to two-piece loading.SOLUTION: An article inspection device comprises: a measurement device 20 for measuring a weight of an article W on a measurement conveyor 22 and determining a state of article quality on the basis of the measured value; a carry-in condition setting unit 31 for setting a condition for an interval Lb that is permissible for the article W being carried in to the measurement conveyor 22; a carry-in interval adjustment conveyor 26 provided upstream of the measurement conveyor 22; and a rear end detection sensor 28 for detecting a rear end of the article W when the article W is carried in from the conveyor 26 to the measurement conveyor 22; an article detection sensor 27 for detecting the tip of the article W being carried in to the carry-in interval adjustment conveyor 26; and a carry-in interval control unit 35 for controlling the speed of the carry-in interval adjustment conveyor 26 from a timing when a rear end of a preceding article W is detected by the rear end detection sensor 28 so that the article W detected by the article detection sensor 27 is carried into an inspection area L1 satisfying the set carry-in interval Lb.SELECTED DRAWING: Figure 1 【課題】２個乗りによる歩留りの悪化を確実に防止しつつ所要の計量精度を担保することができる物品検査装置を提供する。【解決手段】物品Ｗの質量を計量コンベア２２上で計測し、その計測値を基に物品品質状態を判定する計量装置２０と、計量コンベア２２に搬入される物品Ｗの許容できる間隔Ｌｂの条件を設定する搬入条件設定部３１と、計量コンベア２２の上流側に設けられる搬入間隔調整コンベア２６と、そのコンベア２６から計量コンベア２２に物品Ｗが搬入されたときその後端を検知する後端検知センサ２８と、搬入間隔調整コンベア２６に搬入する物品Ｗの先端を検知する物品検知センサ２７と、物品検知センサ２７で検知した物品Ｗが、設定された搬入間隔Ｌｂを満たして検査領域Ｌ１内に搬入するように、後端検知センサ２８で先行物品Ｗの後端を検知したタイミングから搬入間隔調整コンベア２６の速度を制御する搬入間隔制御部３５と、を備えている。【選択図】図１
