を特徴とするバルブの開閉位置検出装置。 An operating shaft that rotates in conjunction with the opening/closing operation of the valve, a detection plate that has at least one slit and moves in conjunction with the rotation of the operating shaft, and a light emitting end and a light receiving end with the detection plate in between. two sets of optical fiber photoelectric detection devices having an end portion and arranged such that an optical axis formed between the light emitting end portion and the light receiving end portion is perpendicular to the surface of the detection plate. , when the bulb is in the open position, light passing through the optical axis formed between the light emitting end and the light receiving end of one optical fiber type photoelectric detection device passes through the slit, and the light passes through the optical axis formed between the light emitting end and the light receiving end of one optical fiber type photoelectric detection device When the light passing through the optical axis formed between the light-emitting end and the light-receiving end of the photoelectric detection device is blocked by the detection plate, and the bulb is in the closed position, the light emission of one optical fiber type photoelectric detection device Light passing through an optical axis formed between the end and the light-receiving end is blocked by the detection plate, and light is formed between the light-emitting end and the light-receiving end of the other optical fiber type photoelectric detection device. A valve opening/closing position detecting device, characterized in that light passing through the shaft passes through the slit.
