PROBLEM TO BE SOLVED: To provide a game machine, even when electromagnetic wave is applied to the game machine by a fraud or the like, preventing malfunction of a main control circuit and protecting respective types of circuits and of devices in a main board.SOLUTION: The game machine according to the present invention comprises main control means, optical repeating means, and first optical transmission means. The optical repeating means includes: a light-receiving device section that receives an optical signal corresponding to prescribed data transmitted from the main control means via the first optical transmission means and converts the optical signal into an electric signal; a light-emitting device section that converts the electric signal converted by the light-receiving device section into an optical signal and transmits the optical signal via second optical transmission means to the outside; a data wiring section that electrically connects the light-receiving device section and the light-emitting device section and transmits the electric signal converted by the light-receiving device section to the light-emitting device section; and a frame section on which the light-receiving device section, the light-emitting device section, and the data wiring section are integrally mounted.SELECTED DRAWING: Figure 13 |
