To prevent the diversion of a board related to an electronic apparatus.

Recessed disconnecting portions 38A and 38B for breaking the connection of a conductive portion 36 are formed on a strobe board 30. Projected connecting portions 28A and 28B corresponding to the disconnecting portions 38A and 38B on the strobe board 30 are formed on a cabinet 24. The surfaces of the connecting portions 28A and 28B are plated with metal, and a conductive pattern 42 is formed which is electrically connected by fitting the connecting portions 28A and 28B into the disconnecting portions 38A and 38B to bring the connecting portions 28A and 28B into contact with the conductive portion 36. If the board 30 is singly used or if the board is assembled into a connected member without the connecting portions 28A and 28B, a conductive pattern to be electrically connected is not formed. Therefore, a strobe lighting device 18 is not actuated. In other words, to form the conductive pattern 42 to be electrically connected, it is required to assembled the board 30 into the cabinet 24. Thus, the diversion of the board 30 is prevented.
