Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a circuit board device which is reduced in power consumption and, in addition, on which maintenance work and inspection work can be performed efficiently. SOLUTION: A mechanical switch is provided in the light emission control circuit of a circuit board and, as long as the mechanical switch is driven, the light emission from a luminous body is inhibited. In addition, the mechanical switch is driven as long as a lid body is positioned to cover the opening of a substrate housing body.
