The invention is to provide a photoelectric sensor fixing mechanism which does not require determining the relative positions of the rack and the conveying conducting member, and occupies little space compared to the anterior photoelectric sensor fixing mechanism. The photoelectric sensor fixing mechanism possesses the following: a photoelectric sensor (300) which possesses a sensing portion (302) which detects an object according to the light flux change in the detection zone; and a fixing pin (500) which fixes the photoelectric sensor (300) on the object. The photoelectric sensor (300) possesses a clamping portion (402) clamping with the fixing pin (500), is arranged at the opposite side (OS) of the detection zone of the object, and the sensing portion (302) is inserted in the sensor hole (203) on the object. The front end portion of the fixing pin (500) passes from the opposite side (OS) of the detection zone side (DS) through the object, and the fixing pin is clamped with the clamping portion (402) of the photoelectric sensor (300). |
