いることを特徴とする光結合装置。 The light-emitting element is molded with a translucent thermosetting resin to form a light-emitting-side translucent resin body, while the light-receiving element is molded with a translucent thermosetting resin to form a light-receiving-side translucent resin body. The light-transmitting resin body on the light-emitting side and the light-transmitting resin body on the light-receiving side are arranged opposite to each other across the passage of the object to be detected, excluding the light-emitting surface of the light-emitting-side transparent resin body and the light-receiving surface of the light-receiving side transparent resin body. The main body of the device is formed by molding with a light-shielding thermoplastic resin, and the device main body is provided with a bearing that supports a movable section that rotates around a horizontal axis in the passageway. Optical coupling device.
