Claims (1)
れた光結合装置本体と、該本体に回転自在に支持
され被検出物体の機械的接触により横軸周りに前
記通過路を通過して検出位置および非検出位置間
を回動する可動切片とを備え、被検出物体の有無
を可動切片の回動により間接的に検出する光結合
装置において、前記可動切片に、可動切片を非検
出位置方向に付勢する復帰用板ばねが一体成形さ
れたことを特徴とする光結合装置。 An optical coupling device body in which a light-emitting part and a light-receiving part are arranged facing each other with a passageway in between, and an object to be detected that is rotatably supported by the body and passes through the passageway around a horizontal axis and is detected by mechanical contact. In an optical coupling device, the optical coupling device includes a movable section that rotates between a position and a non-detection position, and indirectly detects the presence or absence of an object to be detected by rotating the movable section. What is claimed is: 1. An optical coupling device characterized in that a return leaf spring that biases the body is integrally molded.
