GAME MACHINE

To provide a game machine capable of calling predetermined processing without being aware of an interrupt control state when it is called.SOLUTION: A game machine includes arithmetic processing means for performing arithmetic processing for controlling game operation and arithmetic processing for performing processing other than games. When executing predetermined processing, the arithmetic processing means can save an interrupt control state indicating whether a game state is an interrupt prohibition state or an interrupt permission state. The interrupt control state is set to the interrupt prohibition state with an interrupt prohibition instruction and is set to the interrupt permission state with an interrupt permission instruction. The interrupt prohibition state and the interrupt permission state are managed by a first value and a second value respectively that can identify whether the game state is the interrupt prohibition state or the interrupt permission state, and the first value and the second value are set to the same value by the interrupt prohibition instruction and the interrupt permission instruction. The interrupt prohibition instruction is executed after the interrupt control state is saved. The first value is saved after executing the interrupt prohibition instruction.SELECTED DRAWING: Figure 121 【課題】呼び出された際の割込み制御状態を意識することなく、所定処理を呼び出すことができる遊技機を提供する。【解決手段】遊技の動作を制御するための演算処理と、遊技以外の処理を行うための演算処理を行う演算処理手段とを備える。演算処理手段は、所定処理を実行する際に、割込み禁止状態か割込み許可状態かを示す割込み制御状態を退避可能であり、割込み制御状態は、割込み禁止命令で割込み禁止状態、割込み許可命令で割込み許可状態に設定され、それぞれ、割込み禁止状態か割込み許可状態かを識別可能な第１の値、第２の値で管理され、第１の値、及び第２の値は、割込み禁止命令、及び割込み許可命令によって同じ値に設定され、割込み制御状態を退避した後で、割込み禁止命令を実行するように構成され、割込み禁止命令を実行した後で、第１の値を退避する。【選択図】図１２１
