PROBLEM TO BE SOLVED: To provide a cargo handling vehicle intrusion alarm system which can be hardly affected by "stains", "chips" or the like.SOLUTION: A cargo handling vehicle intrusion alarm system determines whether or not a forklift 1 has intruded into a second area A2 from a first area A1 by using a change in a magnetic field where a first magnetic field generation member M1 and a second magnetic field generation member M2 are generated. Therefore, compared to an "alarm system described in a patent document 1 which discriminates a colored area and determines intrusion with a color discrimination sensor", the cargo handling vehicle intrusion alarm system can be hardly affected by "stains", "chips" or the like.SELECTED DRAWING: Figure 1

    【課題】 「汚れ」や「欠け」等の影響を受け難い荷役作業車侵入警報システムを提供する。【解決手段】 第1磁界発生部材M1及び第2磁界発生部M2が発生した磁界の変化を利用して、フォークリフト1が第1領域A1から第2領域(A2)に侵入した否かの判定をする。したがって、「着色領域をカラー判別センサで判別して侵入判定をする特許文献1に記載の警報システム」に比べて、「汚れ」や「欠け」等の影響を受け難い荷役作業車侵入警報システムを得ることが可能となる。【選択図】 図1
