PROBLEM TO BE SOLVED: To provide a safety device capable of more surely preventing an operator from falling from a control platform of a picking lift.SOLUTION: A safety device 10 of the invention comprises: a belt 11 on which a fringe pattern formed of two colors whose brightness is different each other, is provided; a camera 14 directed to the operator who mounts on a predetermined position of a control platform; a pattern storage part 16 for storing a comparison pattern corresponding to the fringe pattern of the belt 11; and an attachment determination part 15 for comparing a binarized image formed by binarization of an original image acquired by the camera 14, and the comparison pattern stored in the pattern storage part 16, and determining that the belt 11 is attached to the operator when there is a pattern approximate to the comparison pattern in the binarized image, and determining that the belt 11 is not attached to the operator when there is no pattern approximate to the comparison patten in the binarized image.

    【課題】ピッキングリフトの運転台から作業者が転落するのをより確実に防止することができる安全装置を提供する。【解決手段】本発明に係る安全装置10は、輝度が異なる2色による縞模様が付されたベルト11と、運転台の所定位置に搭乗した作業者に向けられたカメラ14と、ベルト11の縞模様に対応する比較パターンを格納したパターン格納部16と、カメラ14により得られた元画像を二値化してなる二値化画像とパターン格納部16に格納された比較パターンとを比較し、二値化画像中に比較パターンに近似したパターンがあれば作業者がベルト11を装着しているとの判定をする一方、二値化画像中に比較パターンに近似したパターンがなければ作業者がベルト11を装着していないとの判定をする装着判定部15とを備えている。【選択図】図2
