PROBLEM TO BE SOLVED: To provide a fall-off component detector for a game machine manufacturing line that can detect whether a component has fallen off a constitutive member.SOLUTION: A falling object receptor 22 opened upward is disposed below a carrying conveyor. A moving member 24 is disposed in a freely reciprocating manner inside the falling object receptor 22. The falling object receptor 22 is provided with first detecting switches 28 for detecting that the moving member 24 is located in a first detection position, and second detecting switches 30 for detecting that the moving member 24 is located in a second detection position. A control means stores a set time required for the moving member 24 to move between the first detection position and the second detection position. The moving member 24 located in the first detection position is moved toward the second detection position, and when the second detecting switches 30 do not detect the second detection position in spite of the lapse of the set time, the presence of a fall-off component is determined. |
