Description

The present invention relates to a gaming machine.

Conventionally, as a gaming machine, a slot machine (rotary cylinder type gaming machine) equipped with a plurality of reels in which a plurality of symbols are arranged on an outer peripheral surface, a pachinko gaming machine, and the like are known. This type of gaming machine imparts a certain game value to a game medium such as a medal or a pachinko ball, and plays a game for acquiring such a game medium. Further, some gaming machines have a plurality of stages of setting values having different advantages for the player (see, for example, Patent Document 1). In this type of gaming machine, generally, the higher the set value, the easier it is for the player to acquire the gaming medium. Therefore, the player wants to play a game with a gaming machine having a high setting value rather than a gaming machine having a low setting value. However, such a set value is basically set by the store side (hall side) having the gaming machine, and the player cannot change the set value.

Japanese Unexamined Patent Publication No. 2008-61737

By the way, as described above, there is also a person who tries to perform a so-called goto act of changing a set value that cannot be changed by a normal player by an illegal means. Therefore, it is important for gaming machines to take measures against such goto acts.

On the other hand, in a gaming machine, the storage capacity of a storage means (memory) for storing a program is severely limited due to a rule regarding the gaming machine or the like. For this reason, if the amount of code of the program for preventing / suppressing the goto action becomes large, the capacity of the storage means is consumed in large quantities for the program, and there is a problem that the capacity becomes tight. rice field.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine capable of preventing / suppressing fraudulent activities with a small amount of processing.

In order to solve the above problems, the gaming machine of the present invention
It is equipped with a setting change means for controlling a setting change mode in which the setting value related to the advantage for the player can be changed.
A gaming machine that enters the setting change mode when the power is turned on while the setting key switch is ON, and can change the setting value until the start switch is operated in the setting change mode.
The setting changing means is
The setting change mode is provided on condition that after the start switch is operated in the setting change mode, it is detected that the setting key switch is in the ON state, and then it is detected that the setting key switch is in the OFF state. To finish,
After the start switch is operated in the setting change mode and before detecting that the setting key switch is in the OFF state, if the setting key switch is not detected in the ON state, the setting change mode is terminated. Don't let me
Even when the setting key switch is in the OFF state in the setting change mode, it is possible to execute the process of changing the set value and the process of fixing the set value based on the operation for the start switch.

As a kind of goto action, when the power of the gaming machine is turned on, the gaming machine is made to recognize that the setting key switch is in the ON state by an illegal means, thereby shifting the gaming machine to the setting change mode. Here, in the conventional gaming machine, it is necessary that the setting key switch is in the ON state as a condition for shifting to the setting change mode, but the setting key switch is a condition for ending the setting change mode. Was not required to be in the ON state. For this reason, in the above-mentioned goto action, it is sufficient to set the setting key switch to be in the ON state only for a moment when the power is turned on, and then the setting change mode is performed without performing the operation related to the setting key switch. It was possible to finish it. The gaming machine of the present invention detects that the setting key switch is in the ON state after the start switch is operated in the setting change mode, and then detects that the setting key switch is in the OFF state. By ending the change mode, the ON state of the setting key switch is requested even when the setting change mode is ended. As a result, the operation related to the setting key switch is required even at the end of the setting change mode, so that it is possible to make the goto action difficult.

According to the gaming machine of the present invention, fraudulent activity can be prevented / suppressed with a small amount of processing.

For these input signals transmitted through the input ports 201 to 203, the edge or level of the input signal is detected by the CPU 200 (main IC 300), and predetermined processing is performed according to the detected edge or level.

In the gaming machine of the present embodiment, the CPU 200 (main IC 300) handles all input signals with negative logic. That is, in the above-mentioned OFF state of each input signal, the voltage level of each input signal is High (for example, 5V), and in the above-mentioned ON state of each input signal, the voltage level of each input signal is Low (for example, 5V). , 0V). Then, the CPU 200 has an edge detection process for detecting the switching of the voltage level of each input signal (change point of the input signal: edge) and a level detection for detecting the voltage level of each input signal (state of the input signal itself: level). Do the processing. In this way, edge detection is performed by treating all the input signals input to the CPU 200 (main IC 300), specifically, the input signal to be the target of edge detection and / and the input signal to be the target of level detection with negative logic. It is possible to reduce the amount of code in the program for processing related to processing and processing related to level detection.
In the edge detection process, the switching from High to Low (falling edge) of the input signal is basically detected, but the switching from Low to High (rising edge) may be detected, and the falling edge may be detected. It may be possible to detect both the edge and the rising edge. Further, some or all of the input signals may be processed by positive logic. Further, in the following, the edge of switching from the OFF state to the ON state (basically, the falling edge from High to Low of the input signal) is also referred to as an ON edge. Further, the edge of switching from the ON state to the OFF state (basically, the rising edge from Low to High of the input signal) is also referred to as an OFF edge.

In the gaming machine of the present embodiment, the signal input to the first input port 201 is subjected to the edge detection process, and the signal input to the second input port 202 is not subjected to the edge detection process. In other words, the input signal that is the target of edge detection is input to the first input port 201, but the input signal that is the target of level detection and the input signal that is the target of edge detection are input to the second input port 202. Of these, only the input signal that is the target of level detection is input, and the input signal that is the target of edge detection is not input.

The edge detecting means 400 (main IC 300) performs periodic processing (timer interrupt) at regular intervals (for example, 1.49 ms) from the time when the operation of each button or the detection by the sensor is enabled to the time when the detection by the sensor is disabled. ), And the detection of the current state of the first input port image or the second input port image, that is, the operation state of each button indicated by each input signal input to the first input port 201 or the second input port 202, and each. It detects whether the detection state by the sensor is the OFF state or the ON state. Hereinafter, the detection is referred to as periodic processing. Then, in the periodic processing, the edge detecting means 400 detects the OFF state at the n-1th (previous) periodic processing timing (referred to as the first periodic processing timing), and the nth (nth) after the first periodic processing timing (referred to as the first periodic processing timing). When the ON state is detected at the periodic processing timing (referred to as the second periodic processing timing) of this time), the ON edge of the input signal is detected based on the change from the OFF state to the ON state. For example, in the edge detection means 400 (main IC 300), when the input signal of the first periodic processing timing is in the OFF state and the input signal of the second periodic processing timing is in the ON state, the change from the OFF state to the ON state. The ON edge is detected based on.

Next, the setting change process performed by the setting change means 101 that controls the setting change mode will be described with reference to the flowchart shown in FIG. In the setting change process, the power is turned on and the slot machine X is set in a state where the setting key is inserted into the setting key switch 25 and the setting key is turned 90 degrees clockwise from the initial position (the second state described above). This is the process performed when starting in the change mode. Further, the setting change process refers to the processes of steps S7 to S20 among the processes shown in FIG. Further, whether or not to perform the setting change processing (whether or not to shift to the setting change mode) is determined by the power-on processing means 110 when the power is turned on.
The A register and the C register appearing in the following description are internal registers of the CPU 200.

First, when the power is turned on, the power-on processing means 110 acquires the information of the input signal input to the second input port 202 (step S1). Next, the power-on processing means 110 determines whether or not the input signal of the second input port 202 is valid (step S2). Specifically, the power-on processing means 110 reads the input signal input to the second input port 202 twice, and when the signal read the first time and the signal read the second time match, the first (2) It is determined that the input signal of the input port 202 is valid, and when the signal read for the first time and the signal read for the second time do not match, it is determined that the input signal of the second input port 202 is not valid. Further, the power-on processing means 110 repeats the processing of step S1 and the processing of step S2 until it is determined that the signal of the second input port 202 is valid.

Next, the power-on processing means 110 determines whether or not the setting change condition is satisfied (step S3). Here, the "setting change condition" is a condition for starting the setting change process and a condition for shifting to the setting change mode. Further, "the setting change condition is satisfied" means a state in which the setting key switch 25 is in the ON state (second state) and the door open / close switch 74 is in the ON state (front door 12 is in the open state). Further, "the setting change condition is not satisfied" means a state in which the setting key switch 25 is in the OFF state (first state) or the door open / close switch 74 is in the OFF state (front door 12 is in the closed state).
The establishment / non-establishment of the setting change condition may be determined including conditions other than the state of the setting key switch 25 and the state of the door open / close switch 74, and the state of the setting key switch 25 or the state of the door open / close switch 74 may be determined. The judgment may be made without including it in the condition.

If the setting change condition is not satisfied (NO in step S3), the gaming machine is turned off based on the power-on processing means 110, various initial settings, and backup information stored when the power is cut off (power cutoff). The state is restored to the state before the power failure by performing the state restoration process. In the gaming machine of the present embodiment, at the time of power failure, the setting value data before the power failure and the step of the setting change process before the power failure are processed in the predetermined area (backup area) of the RAM 205 to be backed up. Information indicating whether or not the above has been performed is stored as backup information. Then, when the power is restored from the power failure, the state restoration process is performed based on the backup information.
In the gaming machine of the present embodiment, even if a power failure occurs, the process related to the power failure is not started until the processes of steps S1 to S6 are completed. Therefore, even if a power failure occurs during the processing of steps S1 to S6, it is stored as the backup information that the processing of step S6 has been performed, and when the state recovery processing is performed, the processing from the processing of step S7 is performed. Is to be started. Further, when a power failure occurs during the processing of steps S7 to S20, the processing related to the power failure is started immediately after the processing of each step being executed is completed. Then, when a power failure occurs during the processing of steps S7 to S20, the backup information stores that the processing of the step that was being executed at the time of the power failure was performed, and when the state recovery processing is performed, the next step is performed. The process is started from the process.

When the setting change condition is satisfied (YES in step S3), the power-on processing means 110 resets the information stored in the RAM 205 that is preset to be reset when the setting is changed. (Step S4).

Next, the power-on processing means 110 sets a command indicating the start of the setting change process in the register (step S5). The command is for notifying the sub-control board 72 of the start of the setting change process. Next, the power-on processing means 110 performs subcommand set preprocessing for setting the command set in the register in the RAM 205 (step S6). Then, the command set in the RAM 205 is sent to the sub-control board 72 at a predetermined timing.

Next, the setting changing means 101 starts the setting changing process. During the setting change process, the slot machine X is in the setting change mode.

The setting changing means 101 first performs an edge check process for acquiring the edge information of the input signal (step S7). Here, the input signal to be acquired for edge information includes at least a "setting change switch signal" indicating the operation state of the setting change switch 26 and a "start lever signal" indicating the operation state of the start lever 53. .. The setting change means 101 has ON edge information of the "setting change switch signal" indicating whether or not the setting change switch 26 has been pressed, and ON edge information of the "start lever signal" indicating whether or not the start lever 53 has been pressed. And are set in the C register. In other words, the setting change means 101 indicates whether or not the previous state (n-1st state) of the "setting change switch signal" is the OFF state and the current state (nth state) is the ON state. Information and information indicating whether or not the previous state (n-1st state) of the "start lever signal" is the OFF state and the current state (nth state) is the ON state are set in the C register. do.

Next, the setting changing means 101 acquires the current setting value data stored in the RAM 205 and sets it in the A register (step S8). Here, the setting value data is basically set to any integer value of "0" to "5", and each integer value corresponds to each of setting 1 to setting 6. .. Further, the set value data acquired in step S8 can be said to be data indicating the set value before the power failure.

Next, the setting change means 101 determines whether or not the setting change switch 26 is pressed (step S9). Specifically, it is determined whether or not the setting change switch 26 is pressed based on the ON edge information about the "setting change switch signal" acquired in step S7. More specifically, when the ON edge information of the "setting change switch signal" indicates that the previous state was the OFF state and the current state is the ON state, it is determined that the setting change switch 26 has been pressed. In other cases, it is determined that the setting change switch 26 is not pressed.

When it is determined that the setting change switch 26 is pressed (YES in step S9), the setting change means 101 adds "1" to the current set value data set in the A register (increment of the set value data). To update the set value data (step S10). On the other hand, when it is determined that the setting change switch 26 is not pressed (NO in step S9), the process proceeds to step S11 without updating the set value data.

Next, the setting changing means 101 determines whether or not the set value data set in the A register is within a predetermined range (step S11). Specifically, it is determined whether or not the set value data is within the range of "0" to "5". When the set value data is outside the range of "0" to "5" (NO in step S11), the setting changing means 101 sets the set value data to the specific value "0" within the predetermined range (step S12). ). That is, when the set value data becomes "6" as a result of the increment update in step S10, the set value data is updated to "0" in step S12. Therefore, in the setting change process, the setting value is set 1 (setting value data "0") → setting 2 (setting value data "1") → setting 3 (setting value data "1") based on the pressing operation of the setting change switch 26. 2 ”) → Setting 4 (setting value data“ 3 ”) → Setting 5 (setting value data“ 4 ”) → Setting 6 (setting value data“ 5 ”) → Setting 1 → ... It has become.
The set value data may be a value other than "0" to "6" due to an error or the like, but even if such a value is obtained, the normal value is set to "0" by the processing of steps S11 and S12. It is supposed to go back.

Next, the setting changing means 101 performs a process of returning the set value data set in the A register to the RAM 205 (step S13). By this process, the set value is actually updated. Then, when this process is performed, the set value displayed on the first main display 90 is also updated.

Next, the setting change means 101 determines whether or not the setting change switch 26 is pressed (step S14). Specifically, it is determined whether or not the setting change switch 26 is pressed based on the ON edge information about the "setting change switch signal" acquired in step S7. When it is determined that the setting change switch 26 is pressed (YES in step S14), the setting change means 101 determines whether or not the setting change switch 26 is still pressed (step S15). Then, the setting change means 101 repeats the process of step S15 until it is determined that the setting change switch 26 is not currently pressed. When it is determined that the setting change switch 26 is not currently pressed (NO in step S15), the setting change means 101 performs a process of stopping the setting change process for a predetermined period. Specifically, a value corresponding to the predetermined period is set in the setting change switch pressing interval timer (step S16), wait processing is performed based on the value set in this timer (step S17), and the setting change processing is performed. Stop for a specified period. By performing the processes of steps S14 to S17 in this way, it is possible to prevent adverse effects due to chattering associated with the pressing operation of the setting change switch 26. It should be noted that the processing of steps S14 to S17 may not be performed.

Next, the setting changing means 101 determines whether or not the start lever 53 has been pressed (step S18). Specifically, it is determined whether or not the start lever 53 is pressed based on the ON edge information about the "start lever signal" acquired in step S7. More specifically, when the ON edge information of the "start lever signal" indicates that the previous state is the OFF state and the current state is the ON state, it is determined that the start lever 53 has been pressed, and that is the case. In other cases, it is determined that the start lever 53 is not pressed. If it is determined that the start lever 53 has not been pressed (NO in step S18), the process returns to step S7, and the processes of steps S7 to S18 are repeated until it is determined that the start lever 53 has been pressed. On the other hand, when it is determined that the start lever 53 has been pressed (YES in step S18), the setting changing means 101 determines the set value and proceeds to the process of step S19. That is, in the gaming machine of the present embodiment, the operation for the start lever 53 during the setting change processing (during the setting change mode) is an operation for fixing the set value.
In the first main display 90, the operator indicates that the set value is not fixed during the process of steps S7 to S18 during the setting change process, that is, in a state where the set value can be changed. The set value is displayed in a discriminable manner, and after the process of step S19, that is, in a state where the set value cannot be changed, the set value can be discriminated by the operator that the set value has been determined. Is displayed.

Next, the setting changing means 101 determines whether or not the setting key switch 25 is in the OFF state (step S19). Then, the setting changing means 101 repeats the process of step S19 until it is determined that the setting key switch 25 is not in the OFF state. Further, when the setting changing means 101 determines that the setting key switch 25 is not in the OFF state, the process proceeds to the process of step S20. In other words, the setting changing means 101 repeats the process of step S19 until the ON state of the setting key switch 25 is detected, and when the ON state of the setting key switch 25 is detected, the process proceeds to the process of step S20.

Next, the setting changing means 101 determines whether or not the setting key switch 25 is in the ON state (step S20). Then, the setting changing means 101 repeats the process of step S20 until it is determined that the setting key switch 25 is not in the ON state. Further, when the setting changing means 101 determines that the setting key switch 25 is not in the ON state, the setting changing means ends the setting changing process. In other words, the setting changing means 101 repeats the process of step S20 until the OFF state of the setting key switch 25 is detected, and when the OFF state of the setting key switch 25 is detected, the setting change process ends. Then, the slot machine X shifts from the setting change mode to the game mode or the like.

Information indicating whether the setting key switch 25 (“setting key switch signal”) used in steps S19 and S20 is in the ON state or the OFF state is acquired at predetermined intervals by a timer interrupt as described above. Further, in the gaming machine of the present embodiment, the setting changing means 101 is not based on the edge information indicating that the setting key switch 25 has changed from the ON state to the OFF state (setting key switch 25 (“setting key switch signal””). Although it is possible to terminate the setting change process (without performing edge detection for)), the setting change process may be terminated based on the edge information.

Next, a case where a power failure occurs during the setting change process will be described. The timing of the power failure is (1) before the set value is confirmed (between steps S7 and S18, that is, until it is determined that the start lever 53 is pressed in step S18), and (2) after the set value is confirmed, the setting key. 3 in the loop of the process of detecting the ON state of the switch 25 (process of step S19), (3) in the loop of the process of detecting the OFF state of the setting key switch 25 after confirming the set value (process of step S20). A pattern is possible. Further, as the states related to the setting change condition, (a) the setting key switch 25 is in the ON state and the front door 12 is in the open state (setting change condition is satisfied), and (b) the setting key switch 25 is in the ON state and the front door 12 is in the closed state. (C) The setting change condition is not satisfied. (C) The setting key switch 25 is in the OFF state (the setting change condition is not satisfied (regardless of the state of the front door 12)). Each of these patterns will be described below.

<(1) When a power failure occurs before the set value is confirmed>
First, a case where a power failure occurs before the set value is fixed and the power failure is restored will be described. After recovering from the power failure, the power-on processing means 110 performs the processing of steps S1 to S3.

Then, when the state related to the setting change condition at the time of returning from the power failure is "(a) setting key switch ON, front door open", the setting change condition is satisfied (YES in step S3), so that the setting change means 101 Perform the setting change process in order from the beginning. In other words, the setting changing means 101 will restart the setting changing process from the beginning. However, in the gaming machine of the present embodiment, the set value data stored in the RAM 205 is the target of backup at the time of power failure. Therefore, if a power failure occurs after the processing of step S13, immediately after the power failure is restored. The set value of is not the set value at the start of the setting change process before the power failure, but the set value after being updated in the process of step S13 in the setting change process before the power failure.
If a power failure occurs during the setting change process, the update of the set value data may not be reflected. Further, if a power failure occurs after the set value is confirmed during the setting change process (after YES in step S18), the update of the set value data may be reflected. That is, if a power failure occurs during the setting change process, the setting value at the start of the setting change process after the power failure may be restored may be the setting value at the start of the setting change process before the power failure. The setting value may be set after being updated in the setting change process before the power failure, or may be the setting value confirmed in the setting change process before the power failure.

If the state related to the setting change condition at the time of power failure recovery is "(a) setting key switch ON, front door closed", the setting change condition is not satisfied (NO in step S3), and the process proceeds to the state recovery process. .. In the state recovery process, the power-on processing means 110 returns the slot machine X to the state before the power failure based on the backup information stored in the backup area at the time of power failure. Since the backup information includes information indicating to which step of the setting change processing the processing has been performed, the slot machine X returns to the state before the power failure during the setting change. That is, when the device recovers from the power failure, the setting changing means 101 shifts to the state immediately before the power failure and performs the continuation of the process performed immediately before the power failure. Specifically, for example, when the setting changing means 101 has performed the process up to step S7 before the power failure, the process is performed from step S8 after the power failure is restored, and the process is performed up to step S8 before the power failure. In that case, the process is performed from step S9 after the power failure is restored, and if the process is performed up to step S9 before the power failure, the process is performed from step S10 or step S11 after the power failure is restored.

Further, when the state related to the setting change condition at the time of recovery from power failure is "(c) setting key switch OFF", the same as in (1) (a).

<(2) When a power failure occurs during the loop of the process for detecting the ON state of the setting key switch 25 after the set value is confirmed>
Next, a case where a power failure occurs during the loop of the process of detecting the ON state of the setting key switch 25 after the setting value is confirmed and the setting value is recovered from the power failure will be described. After recovering from the power failure, the power-on processing means 110 performs the processing of steps S1 to S3.

Then, when the state related to the setting change condition at the time of returning from the power failure is "(a) setting key switch ON, front door open", the setting change condition is satisfied (YES in step S3), so that the setting change means 101 Perform the setting change process in order from the beginning. That is, in this case, it is the same as in (1) and (a). Further, in this case, the set value determined before the power failure can be changed again based on the pressing operation of the setting change switch 26.

If the state related to the setting change condition at the time of power failure recovery is "(a) setting key switch ON, front door closed", the setting change condition is not satisfied (NO in step S3), and the process proceeds to the state recovery process. .. Then, after the state return process, the setting changing means 101 shifts to the state immediately before the power failure, and performs the continuation of the process performed immediately before the power failure. Specifically, the setting changing means 101 performs the process of step S19 after returning from the power failure, and determines whether or not the setting key switch 25 is in the OFF state. Here, since the setting key switch 25 is in the ON state, the setting changing means 101 proceeds to the process of step S20 and waits for the setting key switch 25 to be in the OFF state.

If the state related to the setting change condition at the time of power failure recovery is "(c) Setting key switch OFF", the setting change condition is not satisfied (NO in step S3), and the process proceeds to the state recovery process. Then, after the state return process, the setting changing means 101 shifts to the state immediately before the power failure, and performs the continuation of the process performed immediately before the power failure. Specifically, the setting changing means 101 performs the process of step S19 after returning from the power failure, and determines whether or not the setting key switch 25 is in the OFF state. Here, since the setting key switch 25 is in the OFF state, the setting changing means 101 repeats the process of step S19 until the setting key switch 25 is in the ON state.

<(3) When a power failure occurs during the loop of the process for detecting the OFF state of the setting key switch 25 after the set value is confirmed>
Next, a case where a power failure occurs during the loop of the process of detecting the OFF state of the setting key switch 25 after the setting value is confirmed and the setting value is recovered from the power failure will be described. After recovering from the power failure, the power-on processing means 110 performs the processing of steps S1 to S3.

Then, when the state related to the setting change condition at the time of returning from the power failure is "(a) setting key switch ON, front door open", the setting change condition is satisfied (YES in step S3), so that the setting change means 101 Perform the setting change process in order from the beginning. That is, in this case, it is the same as in (1) and (a). Further, in this case, the set value determined before the power failure can be changed again based on the pressing operation of the setting change switch 26.

If the state related to the setting change condition at the time of power failure recovery is "(a) setting key switch ON, front door closed", the setting change condition is not satisfied (NO in step S3), and the process proceeds to the state recovery process. .. Then, after the state return process, the setting changing means 101 shifts to the state immediately before the power failure, and performs the continuation of the process performed immediately before the power failure. Specifically, the setting changing means 101 performs the process of step S20 after returning from the power failure, and determines whether or not the setting key switch 25 is in the ON state. Here, since the setting key switch 25 is in the ON state, the setting changing means 101 repeats the process of step S20 until the setting key switch 25 is in the OFF state.

If the state related to the setting change condition at the time of power failure recovery is "(c) Setting key switch OFF", the setting change condition is not satisfied (NO in step S3), and the process proceeds to the state recovery process. Then, after the state return process, the setting changing means 101 shifts to the state immediately before the power failure, and performs the continuation of the process performed immediately before the power failure. Specifically, the setting changing means 101 performs the process of step S20 after returning from the power failure, and determines whether or not the setting key switch 25 is in the ON state. Here, since the setting key switch 25 is in the OFF state, the loop of step S20 is exited. Then, the setting change process is completed, and the slot machine X shifts from the setting change mode to the game mode.

As described above, the gaming machine of the present embodiment includes the setting changing means 101 for controlling the setting changing mode capable of changing the setting value depending on the advantage for the player, and the power is turned on with the setting key switch 25 turned on. When this is done, the setting change mode is set, and the set value can be changed until the start switch 53 is operated in the setting change mode. In the setting change means 101, the start switch 53 is operated in the setting change mode. After that, when it is detected that the setting key switch 25 is in the ON state and then it is detected that the setting key switch 25 is in the OFF state, the setting change mode is terminated. Therefore, the ON state of the setting key switch 25 is required not only to start the setting change mode (setting change process) but also to end the setting change mode (setting change process). Therefore, since the operation related to the setting key switch 25 is required even at the end of the setting change mode, it is possible to make the goto action difficult and prevent / suppress the goto action.

Further, the gaming machine of the present embodiment includes a setting changing means 101 that executes a setting changing process for changing a setting value that is advantageous to the player when the power is turned on in a state where the setting changing condition is satisfied. If a power failure occurs during the setting change process, or if the setting change condition is satisfied when the power is turned on again, the setting change means 101 executes the process from the beginning of the setting change process and then powers the power again. If the setting change condition is not satisfied when is turned on, the state immediately before the power failure during the setting change processing is restored. Therefore, when a power failure occurs during the setting change process, the gaming machine starts up in the setting change mode regardless of whether or not the setting change condition is satisfied when the power failure is restored. Therefore, when a person who tries to perform a goto act starts the setting change process on the gaming machine, the setting change process cannot be completed only by turning off and turning on the power of the gaming machine. .. Therefore, it is possible to prevent / suppress the act of goto. Further, when the setting change condition is satisfied, the setting change process is performed from the beginning, so that the store clerk or the like can smoothly change the setting. On the other hand, if the setting change condition is not satisfied, the state immediately before the power failure is restored, which eliminates the need for the store clerk to perform the setting change work from the beginning and reduces the work load. be able to.

Further, in the gaming machine of the present embodiment, the setting changing means 101 performs a process of changing the set value based on an operation on the setting change switch 26 even when the setting key switch 25 is in the OFF state in the setting change mode. , The process of fixing the set value based on the operation on the start switch 53 can be executed. Specifically, in the case where the setting key switch 25 is changed from the ON state to the OFF state before the set value is confirmed (before YES is obtained in the process of step S18) during the setting change process (during the setting change mode). Even if there is, the processes of steps S7 to S18 are continued, and it is possible to change the set value based on the operation for the setting change switch 26 and to confirm the set value based on the operation for the start switch 53. It has become. Further, even if a power failure occurs before the setting value is confirmed during the setting change process and the setting key switch 25 is in the OFF state and the power is restored, the operation for the setting change switch 26 can be performed. It is possible to change the set value based on the setting value and to determine the set value based on the operation for the start switch 53. As described above, in the gaming machine of the present embodiment, when the setting change mode is first started or when the setting change mode is ended, the setting key switch 25 needs to be turned on, but the set value is changed. The ON state of the setting key switch 25 is not required when performing the operation of performing the operation or the operation of confirming the set value. Therefore, it is possible to improve the operability related to the change of the set value. Further, in the gaming machine of the present embodiment, when a power failure occurs during the setting change mode, the ON state of the setting key switch 25 is not required even when the setting change mode is restarted.
