GAME MACHINE

To provide a game machine or the like capable of determining whether communication between a dedicated unit and a game point control unit is normal by efficiently performing communication between a main control unit, and the dedicated unit and the game point control unit.SOLUTION: In a main control unit 100, a credit control unit 165 recognizes one of a state of one game token, a state of two game tokens, a state of three to 14,999 game tokens, a state of 15,000 to 16,368 game tokens, and a state of 16,369 game tokens or more. The credit control unit 165 monitors a state of an inter-machine device 300, determines whether an I/F signal common power supply is subjected to VL abnormality (unit communication abnormality), and sets a VL abnormality flag of a bit 2 to 1 and transmits the same to the main control unit 100 along with a VL return wait flag when determining that it is subjected to the VL abnormality. The VL return wait is a flag showing that VLON is not detected at all after power is turned on, and a VL error is not determined if VLON is not detected at all even in the case of the VL abnormality.SELECTED DRAWING: Figure 116 【課題】主制御部と、専用ユニットと遊技点制御部との通信を効率よく行って、専用ユニットと遊技点制御部との通信が正常か否かを判断可能な遊技機等を提供することにある。【解決手段】主制御部１００は、クレジット制御部１６５が遊技メダル数１枚の状態、遊技メダル数２枚の状態、遊技メダル数３枚～１４９９９枚の状態、遊技メダル数１５０００枚～１６３６８枚の状態、遊技メダル数１６３６９枚以上の状態の何れかを認識する。クレジット制御部１６５は、サンド装置３００の状態を監視して、Ｉ／Ｆ信号共用電源のＶＬ異常（ユニット通信異常）か否かを判定しており、異常と判定すると、ビット２のＶＬ異常フラグを１にセットして、ＶＬ復帰待ちフラグと共に主制御部１００へ送信する。ＶＬ復帰待ちは、電源投入後一度もＶＬＯＮを検知していないことを示すフラグであり、ＶＬ異常であっても、一度もＶＬＯＮを検知していなければ、ＶＬエラーとしない。【選択図】図１１６
