In a gaming machine, even if there is a non-mounting area where no electronic component is mounted on a board, the game machine can operate stably. In a test circuit arrangement region 701, a capacitor 722 is mounted and a test IC is not mounted. The test connector placement region 702 does not mount a test connector. Thereby, the input signal circuit arrangement area 703 mounts the input signal IC 724 and the capacitor 725, and the input signal connector arrangement area 704 mounts the input signal connector 723. Thereby, the capacitor 725 functions as a bypass capacitor of the input signal IC 724 and reduces noise accompanying the operation of the input signal IC 724. The capacitor 722 does not function as a bypass capacitor of the test IC, but a function as a noise reduction component of the circuit pattern 711 is expected. [Selection] Figure 87 |
