PROBLEM TO BE SOLVED: To provide an elevator car position detector in which arrangement of a set of combination of a bracket and a shield plate is sufficient even in a case of installing it in a plurality of hoistways having different installation conditions.SOLUTION: The elevator car position detector includes: a shield plate 6 mounted to a bracket 4; and a photoelectric position detector 5. The shield plate 6 includes: a fitting part 10 which has an upper and lower symmetrical shape and is fitted to the bracket 4; a door zone part 11 which determines a door zone region for permitting door opening to be detected by a first detection element 7 of the photoelectric position detector 5; a lower side releveling zone part 12 which determines a lower side permission region to be detected by a second detection element 8; and an upper side releveling zone part 13 which determines an upper side permission region to be detected by a third detection element 9. The second detection element 8 is disposed at a position by a predetermined distance below a virtual horizontal line passing through a center of the first detection element 7, while the third detection element 9 is disposed at a position by the same predetermined distance above the virtual horizontal line.
【課題】設置条件の異なる複数の昇降路内における設置を考慮した場合でも、ブラケットと遮蔽板の組み合わせを1組設ければ済むエレベータ乗かご位置検出装置の提供。【解決手段】本発明は、ブラケット4に取り付けられた遮蔽板6と光電式位置検出器5とを備えている。遮蔽板6は上下対称形状から成り、ブラケット4に取り付けられる取り付け部10と、光電式位置検出器5の第1検出素子7によって検出されるドア開を許容させるドアゾーン領域を決めるドアゾーン部11と、第2検出素子8によって検出される下側許容領域を決める下側リレベリングゾーン部12と、第3検出素子9によって検出される上側許容領域を決める上側リレベリングゾーン部13とを含んでいる。第1検出素子7の中心を通る仮想水平線に対して所定距離下方の位置に第2検出素子8を設け、仮想水平線に対して前述の所定距離と同じ距離上方の位置に第3検出素子9を設けてある。【選択図】図2
