Abstract

PROBLEM TO BE SOLVED: To provide a game machine capable of surely changing setting in a setting change state when control is regularly executed to the setting change state while preventing control to the setting change state by a fraudulent act.SOLUTION: In an operation state in which a setting change operation is performed using a power switch or a setting key switch to be operable when a front surface door is in an open state, the open/closed state of the front surface door is determined (Sa27b). When it is determined that the front surface door is in the open state (YES in Sa27b), a RAM is cleared, control is executed to the setting change state, and thereafter, the setting change state is maintained until a predetermined setting end condition is established regardless of the open/closed state of the front surface door. To the contrary, when it is determined that the front surface door is in a closed state, the RAM is not cleared and control is not executed to the setting change state (NO in Sa27b).

Description

  The present invention relates to gaming machines such as pachinko machines and slot machines. Specifically, the present invention relates to a gaming machine that can change the degree of advantage for a player.

  Conventionally, as an example of such a gaming machine, various devices including a variable display device and a control circuit for controlling these devices are incorporated in the main body, and the front surface of the main body can be opened and closed by a front door. And, by opening the front door and operating a specific operation means built in the main body, it is controlled to the setting change state, and in the setting change state, one of the setting values from a plurality of types of setting values is set. There was something that could be selected and set. The set value determines the probability (winning probability) of allowing the occurrence of a winning (big hit, medium win, small win, bonus, small combination, re-playing combination, etc.). For this reason, the key for opening the front door is held and owned only by a specific store clerk of the game hall, and the setting change can be performed only by a specific store clerk (game room manager) of the game hall. It is configured not to be able to.

  On the other hand, the player's advantage depends on the set value. As a result, the player has performed an illegal act of changing the setting by controlling the setting change state. For example, by opening a hole in the front door or inserting a tool through the gap between the front door and the main unit, operating a specific operating unit or shorting a circuit built in the main unit, There was an act of changing the setting illegally by making it the same as when it was operated.

  As a gaming machine for preventing such illegal acts, a door detection sensor capable of detecting the front door in the closed state is provided, and setting change for changing the setting when the front door is in the closed state in the setting change state There are those that invalidate the signal (for example, see Patent Document 1) and those that report an abnormality (for example, see Patent Document 2).

JP 2004-135844 A JP 2006-61510 A

  However, in the gaming machines described in Patent Documents 1 and 2, even if the front door is in the closed state, it can be controlled to the setting change state. For this reason, even if the front door is in the closed state, there is a possibility that the setting is changed illegally. For example, in the gaming machine described in Patent Document 1, by an action that does not invalidate the setting change signal, and in the gaming machine described in Patent Document 2, by an action that continues the setting change of what is reported to be abnormal In any case, there is a possibility that the setting is changed illegally even though the front door is closed.

  Further, even if the setting change is performed under the control of the setting change state by the game hall administrator, for example, the front door is opened by touching the door detection sensor, for example. When it is determined to be in the closed state, the setting change cannot be performed after that, and there is a possibility that a trouble of newly re-controlling to the setting change state may occur.

  The present invention has been conceived in view of such circumstances, and its purpose is to prevent the setting from being changed to the setting change state by fraud, and to perform the setting when the setting change state is properly controlled. It is an object of the present invention to provide a gaming machine that can reliably change settings in a changed state.

Specific examples of means for solving the problems and their effects

(1) A gaming machine (slot machine, pachinko machine, etc.) capable of changing an advantage (for example, a set value) for a player,
Data storage means (main control section 41) for storing data for controlling the progress of the game in a predetermined storage area (storage area of the RAM of the main control section 41) so as to be readable and writable;
An opening / closing body (front door 1b, body frame 914) provided to be openable and closable;
Operating means (power switch 39, setting key switch 37) that can be operated when the opening and closing body is in an open state;
Open / closed state detecting means for detecting the open / closed state of the open / close body (door open detection switch 25, body frame open detection switch 925);
When the signal for specifying the state of the operation means is in a predetermined state (when the power switch 39 is turned from OFF to ON (when the power switch is turned on), the open / close state detection means) When the open / close state of the open / close body based on the detection result is an open state, it is controlled to a setting change state in which the advantage can be changed by selecting any one of a plurality of setting values ( (Transition to Sa28), when it is in the closed state, it is not controlled to the setting change state (transition to Sa27d) state control means (Sa27b, Sa27d, Sa28, Sa29, FIG. 7 etc.)
When the signal for specifying the state of the operating means is in the predetermined state, the opening / closing state of the opening / closing body based on the detection result of the opening / closing state detecting means is stored in the storage area when the opening / closing state is the open state. Data initialization means (Sa27e in FIG. 6), and data initialization means (Sa27b, Sa27e in FIG. 6) that does not initialize the data stored in the storage area when in the closed state,
After the state control means has controlled to the setting change state, a predetermined setting end condition is satisfied regardless of the detection result of the open / close state detection means in the setting change state (YES in Sc11 of FIG. 7). The setting change state is maintained until (see FIG. 7).

  According to such a configuration, when the open / close state of the opening / closing body when the signal for specifying the state of the operation means is in the predetermined state is the closed state, the setting change state is not controlled, and the data is also initial. It is not converted. In other words, if the opening / closing body is not in an open state, the operating means cannot be operated and cannot be in a predetermined state. When there is a possibility that it has been performed, the setting change state is not controlled, and the data is not initialized. Accordingly, it is possible to reliably prevent the setting change from being performed in the setting change state and the data being initialized due to an illegal act.

  Further, when the signal for specifying the state of the operating means is in a predetermined state when the opening / closing body is in the open state, the setting change state is controlled, and then the setting change state is maintained until the setting end condition is satisfied. Is done. For this reason, after the operation is properly performed rather than cheating, and the setting change state is controlled, the opening / closing body is not touched in the middle of the setting change by touching the opening / closing state detection means. Even in the closed state, the setting change state can be maintained and the setting can be changed reliably.

  Note that the gaming machine may be any gaming machine that can change the advantage to the player, and a game that can change the display state of the variable display device can be started by setting the number of bets for one game. The display state of the variable display device is changed when a slot machine (see the embodiment), a game medium (for example, a pachinko ball) driven into a predetermined game area (game board) passes through a predetermined start area (start port) A pachinko machine that can be used (see Modifications (6) and (7)) may be used.

  In addition, the advantage may be a value related to the degree of advantage for the player, and it is allowed to derive a specific display result (bonus, small combination, re-playing combination, big hit, medium hit, small hit, etc.) It may be a value that determines the probability that it is determined that the derivation of the specific display result is permitted by the pre-determining means that determines whether or not to perform, the probability that information advantageous to the player is notified, the player It may be a value that determines the probability of shifting to a notification state in which information advantageous to the user is notified. In addition, a probability that can be controlled in an advantageous state (bonus, assist time (AT), replay time (RT), jackpot, probability fluctuation state, etc.) advantageous to the player may be defined (modified example) (See (8)).

  Further, the state control means and the data initialization means may each determine the open state of the opening / closing body when a signal for specifying the state of the operation means reaches a predetermined state. It may be determined whether or not a signal for specifying the state of the operation means is in a predetermined state when in the closed state.

  The operation means may be one operation means for detecting one operation, and includes an operation means for detecting the first operation and an operation means for detecting a second operation different from the first operation. A plurality of types of operation means may be included. The state of the operating means refers to the state of the operating portion of the operating means (such as the setting key switch state), and the predetermined state refers to a signal when the state of the operating means is a predetermined state. State (such as when the signal from the setting key switch is ON).

  When the front door (front door 1b) provided so that opening and closing is possible and the operation means can be operated by opening the front door, it can be said that the front door is the opening and closing body ( Slot machine). On the other hand, when the gaming machine main body is provided so as to be rotatable with respect to the outer frame, and the gaming machine main body is rotated to be in an open state, the operation means can be operated. It can be said that the gaming machine body is the opening / closing body (see pachinko machine). In other words, the opening / closing body may be a member that makes the operation means operable by opening it.

  (2) In the gaming machine of (1), when the signal for specifying the state of the operation means is the predetermined state, the open / close state of the opening / closing body based on the detection result of the open / close state detection means is closed If not, notifying means for informing information corresponding to the fact that the data stored in the storage area cannot be initialized (corresponding error code is displayed on the gaming auxiliary display 12, Sa27c in FIG. 6, indicating that RAM cannot be cleared) A notification executed by the sub-control unit 91 when an error command is received.

  According to such a configuration, when it is attempted to initialize data by an illegal act, it is notified that the data cannot be initialized, so that the illegal act can be suppressed.

(3) In the gaming machine of (1) or (2), the operation means is provided on one side (the left side surface of the housing 1a in FIG. 2),
The open / closed state detection means is provided on a different side from the operation means (the right side surface of the housing 1a in FIG. 2) (see FIG. 2).

  According to such a configuration, since the operating means and the open / closed state detecting means are provided on different sides, it is difficult to perform an illegal act on both the operating means and the open / closed state detecting means. Can be increased.

  (4) In the gaming machine according to any one of (1) to (3), when the signal for specifying the state of the operation means is the predetermined state, the opening / closing based on a detection result of the opening / closing state detection means Disabling means (Sa27d, Sa27d ′, Se22a to Se22c, Se35b) for disabling the progress of the game when the body is in the closed state is provided.

  According to such a configuration, when an illegal act is performed, the subsequent progress of the game is disabled. For this reason, it is easily specified by the game hall manager or other players that the illegal act has been performed. As a result, fraud can be suppressed by increasing the risk of performing fraud.

(5) In the gaming machine according to any one of (1) to (4), when the signal for specifying the state of the operation means is the predetermined state, the opening / closing based on a detection result of the opening / closing state detection means Immobilization means (Sa27d, Sa27d ′, Se22a to Se22c, Se35b) for immobilizing the progress of the game when the open / closed state of the body is a closed state;
When the progress of the game is disabled by the disabling device, the signal for specifying the state of the operating device is different from the predetermined state, so that the disabling operation cannot be canceled. Activating release means (Sa27c ′ in FIG. 14).

  According to such a configuration, the immobilization cannot be easily released for a person who has performed an illegal act, but a signal for specifying the state of the operating means by opening the opening / closing body is predetermined. If it is a person who can be in a state different from the state (for example, a game hall manager), the immobilization can be canceled easily and quickly.

(6) In the gaming machine according to any one of (1) to (5), when the signal for specifying the state of the operation means is in the predetermined state, the opening / closing based on a detection result of the opening / closing state detection means Immobilization means (Sa27d, Sa27d ′, Se22a to Se22c, Se35b) for immobilizing the progress of the game when the open / closed state of the body is a closed state;
When the progress of the game is disabled by the disabling device, the disabling device cancels the disabling device by controlling to the setting change state (Sc14 in FIG. 7). , Sc15).

  According to such a configuration, the immobilization cannot be easily released for a person who has performed an illegal act, but a signal for specifying the state of the operating means by opening the opening / closing body is predetermined. If it is a person who can be in a state different from the state (for example, a game hall manager), the immobilization can be canceled easily and quickly.

(7) In the gaming machine according to any one of (1) to (6), when the signal for specifying the state of the operation means is the predetermined state, the opening / closing based on a detection result of the opening / closing state detection means Provided with disabling means (Sa27d, Sa27d ′, Se22a to Se22c, Se35b) for disabling the progress of the game when the open / closed state of the body is a closed state;
The disabling means disables the progress of the game by disabling a specific game operating means among the game operating means for detecting an operation for advancing the game (see Se35b in FIG. 10). ).

  According to such a configuration, since the specific game operation means is invalidated regardless of the progress state of the game before being disabled, the processing for disabling it can be facilitated.

(8) In the gaming machine according to any one of (1) to (7), when the signal for specifying the state of the operation means is the predetermined state, the opening / closing based on a detection result of the opening / closing state detection means Provided with disabling means (Sa27d, Sa27d ′, Se22a to Se22c, Se35b) for disabling the progress of the game when the open / closed state of the body is a closed state;
Even when the progress of the game is disabled by the disabling means, the same game as when the disabling is not performed until the timing at which the game progresses by operating the specific game operation means Is controlled (Se22b, Se33 in FIG. 10).

  According to such a configuration, it is not necessary to perform special control for disabling until a specific game operation means is operated, and an increase in processing load can be prevented.

A motor 34 b is connected, and these electric components are driven based on the control of the main control unit 41 mounted on the game control board 40.

  The game control board 40 includes a main control unit 41, a random number generation circuit 42, a sampling circuit 43, a switch detection circuit 44, a motor drive circuit 45, a solenoid drive circuit 46, an LED drive circuit 47, a power interruption detection circuit 48, and a reset circuit 49. Is installed.

  The main control unit 41 is constituted by a one-chip microcomputer having a main CPU, ROM, RAM, and I / O port, and executes a control program stored in the ROM to execute processing related to the progress of the game. In addition to controlling the game, each part of the control circuit mounted on the game control board 40 is controlled directly or indirectly.

  The random number generation circuit 42 includes a counter that counts up and updates a value every time a predetermined number of pulses are generated, and generates a random number within a predetermined range. The sampling circuit 43 acquires (latches) the numerical value counted by the random number generation circuit 42. In the random number generation circuit 42, 0 to 65535 is defined as a range of numerical values to be counted.

  The main control unit 41 sends an instruction to the sampling circuit 43 to acquire the numerical value indicated by the random number generation circuit 42 as a random number (hereinafter, this function is referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are processed by software instead of using the random numbers extracted by the hardware random number function as they are. The main control unit 41 also has a function of updating a numerical value of a specific register by the above-described timer interrupt process (main) and acquiring the updated numerical value as a random number (hereinafter, this function is a software random number function). Called).

  The switch detection circuit 44 takes in detection signals input from switches connected directly to the game control board 40 or via the power supply board 101 and transmits them to the main control unit 41. The motor drive circuit 45 transmits the motor drive signal output from the main control unit 41 to the reel motors 32L, 32C, and 32R. The solenoid drive circuit 46 transmits the solenoid drive signal output from the main control unit 41 to the flow path switching solenoid 30. The LED drive circuit transmits the LED drive signal output from the main control unit 41 to various displays and LEDs connected to the game control board 40.

  The power interruption detection circuit 48 monitors the power supply voltage supplied to the slot machine 1 and outputs a voltage drop signal indicating that to the main control unit 41 when a voltage drop is detected. The reset circuit 49 gives a reset signal to the main control unit 41 in a state where the power supply is unstable, such as when the power is turned on or when the power is turned off.

  The main control unit 41 receives the detection state of various switches connected to the game control board 40 from the input port. Then, the main control unit 41 executes basic processing that shifts in stages according to the detection states of various switches input from these input ports.

  Further, the main control unit 41 can execute an interrupt process by interrupting the basic process when an interrupt occurs. In the present embodiment, the external maskable interrupt terminal XINT is connected to the power interruption detection circuit 48 described above, and the main control unit 41 will be described later according to the input of the voltage drop signal output from the power interruption detection circuit 48. Execute the power interruption interrupt processing (main). Further, the main control unit 41 executes a timer interrupt process (main), which will be described later, every time a time-out occurs in the timer circuit, that is, every fixed time interval (about 0.56 ms in this embodiment).

  The main control unit 41 is set to prohibit other interrupts during the execution of the interrupt process, and when a plurality of interrupts occur at the same time, the main control unit 41 prioritizes according to a predetermined order. An interrupt to be executed is set. In this embodiment, the interruption interrupt process (main) has a higher priority than the timer interruption process (main), and when these interruptions occur simultaneously, the interruption interruption process (main) Is executed with priority.

  If another interrupt factor occurs during the execution of the interrupt process and the interrupt factor continues even after the interrupt process ends, a new interrupt occurs at that point. It will be. For example, if a voltage drop signal is input during execution of the timer interrupt process (main), the power interruption interrupt process (main) is not executed at that time, but the timer interrupt process being executed When the input of the voltage drop signal is continued when (main) is completed, the power interruption interrupt process (main) is executed at that time.

  The main control unit 41 repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 changes as a basic process, and changes the detection state of the various switches. Execute a process that moves in stages. In addition, the main control unit 41 executes a power interruption interrupt process (main) in response to the input of the voltage drop signal output from the power interruption detection circuit 48, and at a constant time interval (in the present embodiment, about 0. 0). Timer interrupt processing (main) is executed every 56 ms).

  Note that the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repetition of the process depending on the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The main control unit 41 transmits various commands to the effect control board 90. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. Command transmission from the game control board 40 to the effect control board 90 is performed by serial communication. The game control board 40 and the effect control board 90 are not limited to being directly connected, and may be configured to be connected via a relay board, for example.

  The effect control board 90 is connected to effect devices such as a liquid crystal display 51 (see FIG. 1), an effect LED 52, speakers 53 and 54, and the reel LED 55 described above, which are arranged on the front door 1b of the slot machine 1. These effect devices are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  In the present embodiment, the sub-control unit 91 mounted on the effect control board 90 performs output control of effect devices such as the liquid crystal display 51, effect effect LEDs 52, speakers 53 and 54, and reel LEDs 55. However, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board separately from the sub control part 91, and the sub control part 91 is based on a command from the main control part 41. The output pattern of the effect device may be determined, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output The output control of the effect device is performed by both of the control units.

  Moreover, in this Embodiment, although the liquid crystal display 51, the effect effect LED52, the speakers 53 and 54, and the reel LED55 are illustrated as an effect device, an effect device is not restricted to these, For example, it drives mechanically. A display device or a mechanically driven item may be applied as the rendering device.

  The effect control board 90 is composed of a microcomputer having a sub CPU 91a, ROM 91b, RAM 91c, I / O port 91d, etc., and a liquid crystal display connected to the sub control unit 91 for effect control and the effect control board 90. Display control circuit 92 for performing display control of device 51, LED drive circuit 93 for controlling drive of effect LED 52 and reel LED 55, sound output circuit 94 for controlling sound output from speakers 53, 54, when power is turned on or when power is turned off A reset circuit 95 that sometimes gives a reset signal to the sub CPU 91a, a clock device 97 that outputs time information including date information and time information, and a power supply voltage supplied to the slot machine 1 are monitored, and when a voltage drop is detected, A power interruption detection circuit 9 for outputting a voltage drop signal indicating that to the sub-control unit 91 The sub-control unit 91 receives commands transmitted from the main control unit and performs various controls for performing effects, and directly controls each part of the control circuit mounted on the effect control board 90. To control automatically or indirectly.

  Similar to the main control unit 41, the sub control unit 91 has an interrupt function, generates an interrupt when receiving a command from the main control unit 41, and acquires a command transmitted from the main control unit 41. Execute command reception interrupt processing to be stored in the buffer. Further, the sub control unit 91 executes an interrupt process (sub), which will be described later, by generating an interrupt every time the number of input system clocks reaches a certain number, that is, every certain interval. Also, one of the interrupt terminals of the sub control unit 91 is connected to the power interruption detection circuit 98, and the sub control unit 91 is turned on in response to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute interrupt processing (sub).

  Also, unlike the main control unit 41, the sub control unit 91 interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the reception of the command. The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time. Command reception interrupt processing is also prohibited during the execution of power interruption interrupt processing (sub), but if an interrupt that triggers power interruption interrupt processing (sub) occurs at the same time, command reception Prioritize interrupt processing.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the set value, the front door 1b is opened, and the power switch 39 and the setting key switch 37 of the power box 100 provided in the housing 1a are operated to turn on the power of the slot machine 1. In such a case, the slot machine 1 needs to be turned on after the setting key switch 37 is turned on. The set value selected and set according to the operation is stored in the RAM of the main control unit 41. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM of the main control unit 41 is displayed on the setting value display 24 as a display value, and the setting value by the operation of the reset / setting switch 38 is displayed. Transitions to a setting change state where a change operation is possible. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned off, the determined display value (setting value) is stored in the RAM of the main control unit 41, and the state shifts to a state in which the game can proceed. Since the power switch 39 is temporarily turned off, and the setting key switch 37 is turned on to perform the operation of turning on the power switch 39, the operation is shifted to the setting change state. .

  In the present embodiment, since the setting change operation can be performed by opening the front door 1b, it can be said that the front door 1b is an opening / closing body. Moreover, it can be said that the door open detection switch 25 for detecting the open state of the front door 1b is an open / closed state detecting means.

  In order to check the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. In this situation, when the setting key switch 37 is turned on, the setting value read out from the RAM of the main control unit 41 is displayed on the setting value display 24, so that the setting value can be confirmed. Transition. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main control unit 41 detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a RAM stack of the main control unit 41 (to be described later), and one of the bits in the RAM of the main control unit 41 is destructive diagnosis data (this embodiment) Then, for example, 5AH), that is, the specific data other than 0 is stored, and the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM of the main control unit 41 becomes 0 Then, the process of storing in the RAM of the main control unit 41 is performed. The RAM parity is a value calculated as an exclusive OR of the values stored in each bit of the corresponding area (all areas in the present embodiment) of the RAM of the main control unit 41. For this reason, if the RAM parity based on the data stored in all areas of the RAM of the main control unit 41 is 0, the RAM parity adjustment data is 0, and is stored in all areas of the RAM of the main control unit 41. If the RAM parity based on the data is 1, the RAM parity adjustment data is 1.

  The main control unit 41 calculates the RAM parity based on the data stored in all areas of the RAM of the main control unit 41 at the time of activation, confirms the value of the destructive diagnosis data, and the RAM parity is The processing state of the main control unit 41 is restored to the state before the power interruption based on the data stored in the RAM of the main control unit 41 on the condition that the value of the data for destructive diagnosis is also correct. If the RAM parity is not 0 (in the case of 1) or the value of the destructive diagnosis data is incorrect, it is determined that the RAM is abnormal, the RAM abnormal error code is set in the register, and the RAM abnormal error state is controlled. The progress of the game is disabled. Unlike the normal error state, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In the present embodiment, all the data stored in the RAM of the main control unit 41 is held by the backup power source even in the event of a power failure, and the main control unit 41 is connected to the main control unit 41 when the power is turned on. When it is determined that the data in the RAM is normal, the configuration is such that the control state before power interruption is restored based on the stored data in the RAM of the main control unit 41, but is stored in the RAM of the main control unit 41. A configuration may be adopted in which only data necessary for returning to the control state at the time of a power failure is backed up, and the control state before power interruption is restored based on the backed-up data at power-on.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore all the states of the input ports to the state before power interruption.

  Further, when the sub control unit 91 detects the voltage drop signal from the power interruption detection circuit 98, the sub control unit 91 executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0, and stored in the RAM 91c.

  Then, the sub-control unit 91 calculates the RAM parity based on the data stored in all the areas of the RAM 91c at the time of activation, and sets the data stored in the RAM 91c on the condition that the RAM parity is 0. Based on this, the processing state of the sub-control unit 91 is restored to the state before the power interruption, but when the RAM parity is not 0 (in the case of 1), it is determined that the RAM is abnormal and the RAM 91c is initialized. . In this case, unlike the main control unit 41, only the RAM 91c is initialized, and the performance is not disabled.

  In the present embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub-control unit 91 determines that the data in the RAM 91c is normal when the power is turned on. In this case, the control state is restored to the control state before the power interruption based on the data stored in the RAM 91c, but only the data necessary for the return of the control state in the event of a power failure is backed up among the data stored in the RAM 91c. It is good also as a structure which returns to the control state before power interruption based on the data backed up at the time of injection | throwing-in.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is only necessary to restore the state of the input port, and it is not necessary to restore the state of the input port or the progress in the case where the production is interrupted in the middle to the state before the power interruption.

  Next, initialization of the RAM mounted on the main control unit 41 will be described. The RAM storage area of the main control unit 41 is divided into important work, general work, special work, set value work, unsaved work, unused area, and stack area.

  The important work is a work in which data which is inconvenient if it is initialized at the end of the BB, such as various display devices, LED display data, I / O input / output data, and game time counter. The general work is a work that stores data that can be initialized at the end of the BB, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the BB.

  The special work is a work that stores data to be initialized only before the start of setting, such as data for transmitting a command to the effect control board 90 and various software random numbers. The set value work is a work that stores a set value used when a lottery is performed in the internal lottery process. The non-saved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM of the main control unit 41 is destroyed at the time of activation.

  The unused area is an unused area in the RAM storage area of the main control unit 41, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main control unit 41 is stored, and the unused stack area is one of a plurality of initialization conditions to be described later, like the unused area. However, if it is established, it will be initialized, but the in-use stack area is not initialized because the program continues.

  The main control unit 41 stores the data for controlling the game in the storage area of the RAM so that it can be read and written as the game progresses in the slot machine.

  In the present embodiment, the main control unit 41 is activated when the setting key switch 37 is ON, when a RAM error occurs, when the BB ends, or when the setting key switch 37 is OFF. When the RAM data of 41 is not destroyed, when four initialization conditions at the end of one game are satisfied, four types of initializations with different areas initialized according to each initialization condition are performed. Do.

  Initialization 1 is a state in which the setting key switch 37 is in an ON state at the time of start-up, and is an initialization performed before the transition to the setting change state or an initialization performed when a RAM abnormality error occurs. In the storage area of the RAM of the main control unit 41, all areas (including the unused area and the unused stack area) except the used stack area are initialized.

  The information initialized in the initialization 1 includes, for example, information backed up at the time of power interruption (information for specifying the set number of bets, information for specifying BB winning). As a result, when initialization 1 is performed, even if the bet number is set before the power interruption, the bet number is not returned to the set state, and the BB is won before the power interruption. Even if it does, it will not return to the BB winning situation. Thereby, it is possible to prevent the game state before the setting change state from being taken over after entering the setting change state, and to ensure the fairness of the game.

  Initialization 2 is initialization performed at the end of the BB. In initialization 2, the general work, the unused area, and the unused stack area in the RAM storage area of the main control unit 41 are initialized. Initialization 3 is initialization performed when the setting key switch 37 is in an OFF state at the time of startup and the RAM data of the main control unit 41 is not destroyed. Unused areas and unused stack areas are initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the RAM storage area of the main control unit 41 are initialized.

  In this embodiment, the initialization 1 is performed before the setting change state is transferred. However, the initialization 1 is performed at the end of the setting change state, or both before the setting change state and at the end of the setting change state. May be. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the initialization of the set value work is not performed in the initialization at the end of the setting change state.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, as will be described later, there are a regular bonus (hereinafter referred to as RB), a big bonus (hereinafter referred to as BB), and a normal gaming state as gaming states. 2 is defined as the prescribed number, and 3 is defined as the prescribed number of bets in the normal gaming state. For this reason, if the gaming state is RB or BB, the game can be started if 2 is set as the bet number, and if the bet number is set to 3 in the normal gaming state, the game is started. It becomes possible to make it. In this embodiment, all the pay lines L1 to L5 are activated when a specified number of bets according to the gaming state are set, and as RBs and BBs, All winning lines L1 to L5 are activated when 2 is determined, and all winning lines L1 to L5 are activated when 3 is set as the number of bets in the normal gaming state. Become.

  In the slot machine 1 of the present embodiment, when all the reels 2L, 2C, and 2R are stopped, the winning line that is activated (in this embodiment, all the winning lines are always activated, In the following description, an activated winning line is simply referred to as a winning line). The combination may be a combination of the same symbols or a combination including different symbols.

  The types of winning combinations are determined according to the gaming state, but can be broadly divided into small roles with payout of medals and re-starts that allow the next game to be started without the need to set bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order to win each winning combination determined according to the gaming state, it is necessary to win an internal lottery to be described later and set a winning flag for the winning combination in the RAM of the main control unit 41.

  Of the winning flags for each of these roles, the winning flags for the small role and the replaying role are valid only in the game in which the flag is set, and are invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  As shown in FIG. 5, the slot machine 1 has a big bonus (hereinafter referred to as BB as a big bonus) and a regular bonus (hereinafter referred to as RB as a regular bonus) as a special role. Cherry, Bell are replayed as a re-playing role.

  Cherry is awarded when the symbol “white cherry” is derived on any of the winning lines for the right reel in any gaming state, and one medal is paid out in any gaming state. If the symbol “white cherry” stops at the upper or lower stage of the right reel, the combination of cherries will be aligned on the two winning lines of the winning lines L2, L5 or the winning lines L3, L4. Since winning a cherry on the winning line, two medals will be paid out.

  A watermelon is awarded when a combination of "Watermelon-Watermelon-Watermelon" or "Watermelon-Watermelon-BAR" is available on any of the winning lines in any game state, and 15 medals at RB and BB Are paid out, and in the normal gaming state, 12 medals are paid out. A bell is awarded when a combination of “bell-bell-bell” is aligned on any of the winning lines in any gaming state, 15 medals are paid out in RB and BB, and 10 in the normal gaming state. A medal is paid out.

  Replay is a combination of “Replay-Replay-Replay”, “BAR-Replay-Replay”, or “Black 7-Replay-Replay” in any of the winning lines in the normal gaming state. Wins when you have the right. When the replay wins, no medals are paid out, but the next game can be started without setting the number of wagers again, so that three medals corresponding to the number of wagers that are not required to be set in the next game are paid out. Is essentially the same.

  RB is won when the combination of “net 7-net 7-black 7” is aligned on any of the winning lines in the normal gaming state, and the gaming state shifts to RB. The RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of the small role, particularly the bell, and when the 12 games are digested after the RB starts, or an 8-game winning ( When the type of a combination is allowed), it ends either whichever comes first.

  BB is a combination of “black 7-black 7-black 7”, “net 7-net 7-net 7” or “white 7-white 7-white 7” in any of the winning lines in the normal gaming state. When the combination is complete, a prize is awarded.

  When BB wins, the gaming state shifts to BB and shifts to RB at the same time. When RB ends, if BB has not ended, it shifts to RB again and is controlled repeatedly until BB ends. The That is, during BB, it is always controlled to RB. The BB ends when the total number of medals paid out to the player in the BB exceeds 465. At the end of the BB, the RB is also ended regardless of whether or not the RB end condition is satisfied.

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random value for internal lottery (an integer from 0 to 65535) is acquired when the start switch 7 is detected. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, numerical data stored in the lottery work, and determination of each combination determined according to the gaming state, the number of bets and the set value This is done according to the number of values.

  In the present embodiment, as shown in FIG. 5, the role that is the subject of the internal lottery differs depending on whether the gaming state is the normal gaming state, RB, or BB. Further, when the gaming state is the normal gaming state, the role to be subject to the internal lottery varies depending on whether or not the special role is being carried over.

  When the gaming state is the normal gaming state and any special combination is not carried over, BB, RB, replay, watermelon, cherry, and bell are sequentially read out as the target combination of the internal lottery.

  When the gaming state is the normal gaming state and any special combination is carried over, replay, watermelon, cherry, and bell are sequentially read out as the target combinations for the internal lottery.

  When the gaming state is RB (including the inside of the BB), watermelon, cherry, and bell are sequentially read out as the subject combination of the internal lottery.

  In the present embodiment, an example is described in which three types of symbol combinations corresponding to BB, three types of symbol combinations corresponding to replay, and two types of symbol combinations corresponding to watermelon are defined. Then, each symbol combination is read out as a target combination. For example, for BB, a combination of “black 7-black 7-black 7”, a combination of “net 7-net 7-net 7”, and a combination of “white 7-white 7-white 7” are subject to internal lottery. Are read in order. Replays and watermelons are also sequentially read out as target combinations for each symbol combination. The number of determination values used in the internal lottery is determined for each symbol combination corresponding to the set values 1 to 6. That is, the winning rate is determined for each symbol combination corresponding to the set values 1 to 6. For this reason, in the internal lottery, the derivation (generation) of the symbol combination is permitted according to the winning rate determined for each symbol combination corresponding to the set value.

  In the internal lottery, the number of judgment values determined according to the internal lottery target, the current game state, and the set value are sequentially added to the internal lottery random value (the value of the lottery work) and added. When the result of overflows, it is determined that the winning combination is won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  When a winning combination is determined, a winning flag corresponding to the winning combination is set in the internal winning flag storing work assigned to the RAM of the main control unit 41. The internal winning flag storage work consists of a storage area of 2 bytes, of which the upper byte is assigned as the special role storing work for which the special role winning flag is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination or winning combination is won, only the general winning combination work is cleared.

Next, stop control of the reels 2L, 2C, 2R will be described.
The main control unit 41 generates a table index and a table that are stored in the ROM of the main control unit 41 when the rotation of the reel starts and when the reel is stopped and the reel that is still rotating still remains. Referring to the data, a stop control table is created for each rotating reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even if the winning status of the combination is different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address And to be able to identify the stop control table. Even when the stop status of the reels and the stop position of the stopped reels are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames by timing at which the stop operation is performed. In the present embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. Then, 21 areas (frames) divided every 16 steps (the number of steps that one symbol moves) are defined for one reel, and these areas are areas 0 to 20 from the reel reference position. A number is assigned.

  On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number has a stop reference position (in this embodiment, a perspective window). 3 when the operation of the stop switches 8L, 8C, 8R is detected at the timing (the timing in which the number of steps from the reel reference position is included in the range of the number of steps). This is a table in which the number of frames is set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the obtained table creation data, and the address of the stop control table for the unreacted reel corresponding to the stop reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main control unit 41 effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel is described. To explain, when any operation corresponding to the rotating reel is detected effectively among the stop switches 8L, 8C, 8R, the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. The number of sliding symbols corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames.

  Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. Thus, the region corresponding to the region number that is the stop position ahead of the number of sliding frames from the region corresponding to the region number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the fluoroscopic window 3 The lower symbol area).

  In the table index of the present embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). That is, the table creation data corresponding to one internal winning state in one gaming state and the stop control table corresponding to the reel stop status (and the stop position of the stopped reel) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

  Further, in the present embodiment, a value of 0 to 4 is determined as the number of sliding frames, and it is possible to stop the reel by drawing a maximum of 4 frames after detecting a stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In the present embodiment, when any of the winning combinations is won, the winning combination is drawn to the maximum in the range of 4 frames on the winning line, and the winning combination is drawn not to be aligned on the winning line. Create a stop control table with the number of sliding symbols and perform reel stop control. If none of the roles are won, stop control with the number of sliding symbols that do not match any of the roles A table is created and reel stop control is performed. As a result, when a stop operation is performed, if the winning combination can be stopped on the winning line within the drawing range of a maximum of 4 frames, the control is performed so that the winning combination is stopped. If the winning combination is not drawn, it will be controlled so that it can be stopped in a drawing range of up to 4 frames.

  When a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the winning small role is the maximum in the range of 4 frames on the winning line. The number of sliding frames is fixed so that it can be drawn to the limit, and for the stop operation position where the selected small role cannot be drawn in the range of up to 4 frames in the winning line, the winning special role is in the range of 4 frames in the winning line A stop control table in which the number of sliding frames is determined so as to be pulled in as much as possible is created, and the reel stop control is performed.

  As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, the control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, Control is performed to align and stop them, and a winning combination that has not been won will be controlled to be stopped within the 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn. When a special combination and a small combination can be withdrawn at the same time, only the small combination is withdrawn and the small combination is not aligned on the winning line at the same time as the special combination.

  In this embodiment, when a special role is elected while the special role has been carried over from before the previous game, or when a special role and a small role are won simultaneously, the special role and the small role are won simultaneously. In such cases, the selected special role has priority over the selected special role, and only when the small role cannot be withdrawn, the special role is controlled on the winning line. If both are elected at the same time, priority is given to the control of aligning the special role on the winning line over the small role, and the control of aligning the small role on the winning line may be performed only when the special role cannot be drawn. .

  If a special player and a replaying player are elected at the same time, such as when a replaying player is elected while the special role has been carried over from before the previous game, the winning line will be displayed when the stop operation is performed. In addition, the control is performed so that the symbols of the re-gamer are aligned and stopped within a maximum of 4 frames. In this case, the symbols constituting the re-gamer or the symbols constituting the re-gamer elected at the same time are arranged within 5 symbols for each of the reels 2L, 2C and 2R, that is, at intervals of 4 frames or less. Since it can always be stopped at any position within the 4-frame pull-in range, if the special combination and the re-playing combination are elected at the same time, the timing of the operation of the stop switches 8L, 8C, 8R by the player Without fail, the re-playing role will always be won. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win. In the case where the special role and the replaying role can be withdrawn at the same time, only the replaying role is drawn in, and the special role is not arranged on the winning line at the same time as the replaying role.

  In the present embodiment, the main control unit 41 rotates the reels for which the stop operation has not yet been detected until the operation of the stop switches 8L, 8C, 8R is detected after the rotation of the reels 2L, 2C, 2R is started. And the control to stop the display result on the corresponding reel is performed on the condition that the operation of the stop switches 8L, 8C, 8R is detected. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the operation of the stop switches 8L, 8C, and 8R is detected by continuing the rotation of the reels that have not been operated.

  In the present embodiment, the control of stopping the display result on the corresponding reel is performed on the condition that the operation of the stop switches 8L, 8C, and 8R is detected, but the rotation of the reel is started. Then, when a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. It may be. In this case, since the reels are stopped without the player's operation, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  Next, a command that the main control unit 41 transmits to the effect control board 90 will be described.

  In the present embodiment, the main control unit 41 makes a BET command, a credit command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command, A plurality of types of commands including a game state command, a standby command, a stop command, an error command, a return command, a setting start command, a confirmation start command, and a confirmation end command are transmitted.

  These commands consist of 1-byte type data indicating the command type and 1-byte extension data indicating the command content, and the sub-control unit 91 can determine the command type from the type data.

  The BET command is a command that can specify the number of inserted medals, that is, the number of medals used to set the bet number, and is a state from the end of the game (after setting change) to the start of the game. Sent when a medal is inserted or the bet number is set by operating the single BET switch 5 or the MAXBET switch 6 in a state where is not set. Further, since the BET command is transmitted when the betting number setting operation is performed, it is possible to specify that the betting number setting operation has been performed by receiving the BET command.

  The credit command is a command that can specify the number of medals stored as credits, and is a state from the end of the game (after setting change) to the start of the game, and in a state where a predetermined number of bets is set, Sent when a medal is inserted and credits are added.

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag that has been established, and is transmitted when the start switch 7 is operated to start the game. Further, since the internal winning command is transmitted when the start switch 7 is operated, it is possible to specify that the start switch 7 has been operated by receiving the internal winning command.

  The reel rotation start command is a command for notifying the start of reel rotation, and is transmitted when rotation of the reels 2L, 2C, and 2R is started.

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. And is transmitted every time stop control is performed in accordance with the stop operation of each reel. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. .

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out when winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals is started by paying out a prize or credit (including medals used for setting the number of bets). The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The gaming state command is a command that can specify the gaming state of the next game, and is transmitted when the setting change state ends and when the game ends.

  The standby command is a command indicating a transition to the standby state, and after one game is over, a credit (which was used for setting the bet number) is set when the transition to the standby state is made after a predetermined time without setting the bet number. (Including medals) is sent out after the medal payout is completed and the payout end command is sent.

  The stop command is a command indicating the occurrence or release of the stop state, and after the end of the BB, the stop command indicating the occurrence of the stop state is transmitted when the ending effect waiting time has elapsed, and the reset operation is performed. When the stop state is released, a stop command indicating the release of the stop state is transmitted.

  An error command is a command that indicates the occurrence or cancellation of an error condition and the type of error condition. When an error is determined and controlled to an error condition, an error command indicating the occurrence and type of the error condition is sent and reset. When the error state is canceled after the operation is performed, an error command indicating the cancellation of the error state is transmitted.

  The return command is a command indicating that the main control unit 41 has returned to the control state before the power interruption, and is transmitted when the main control unit 41 returns to the control state before the power interruption.

  The setting start command is a command indicating the start of the setting change state, and is transmitted when shifting to the setting change state. Further, since the control state of the main control unit 41 is initialized with the transition to the setting change state, it can be specified that the control state of the main control unit 41 has been initialized by the setting start command.

  The confirmation start command is a command indicating the start of the setting confirmation state, and is transmitted when shifting to the setting confirmation state. The confirmation end command is a command indicating the end of the setting confirmation state, and is transmitted when the setting confirmation state ends.

  Among these commands, a setting start command, an error command indicating a RAM error or a random number circuit error, and a return command are generated at a stage before an interrupt is permitted in the startup process and assigned to a special work in the RAM of the main control unit 41. The specified command transmission buffer is stored and transmitted immediately.

  Commands other than a setting start command, an error command indicating a RAM abnormality or a random circuit error, and a return command are generated according to the progress of the game in the game process, and are provided as special commands provided in a special work in the RAM of the main control unit 41. The data is temporarily stored in the transmission buffer and transmitted in the command transmission process executed in the timer interrupt process (main).

  Next, various control contents executed by the main control unit 41 in the present embodiment will be described below with reference to FIGS.

  When a reset factor occurs, the main control unit 41 performs a startup process (main) shown in the flowchart of FIG. As a reset factor, a system reset that occurs when a low level signal is input to the external system reset terminal for a certain period at power-on, a time-out signal of a watchdog timer (WDT), There is a user reset such as the occurrence of prohibition of travel outside designated area (IAT). For this reason, the activation process (main) is a process that is performed when the main control unit 41 is activated when the power is turned on and when the main control unit 41 is activated due to a malfunction.

  In the startup process (main), first, the CPU of the main control unit 41 executes the security check process based on the security check program read from the ROM (Sa1). At this time, the main control unit 41 is in the security mode, and the game control user program stored in the ROM of the main control unit 41 is not yet executed.

  After completing the security check process of Sa1, the main control unit 41 initializes the built-in device, peripheral IC, interrupt mode, stack pointer, and the like (Sa2), and then initializes the value of a predetermined register (Sa3). By register initialization, an interrupt table address to be referred to when an interrupt occurs, a reference address for referring to the RAM storage area of the main control unit 41, and the like are set. These values are fixed values and are always initialized at startup.

  Next, access to the RAM of the main control unit 41 is permitted (Sa4), and RAM parities of all storage areas (including unused areas and unused stack areas) of the RAM of the main control part 41 are calculated (Sa5). Then, the status of the stop switch 36 and the automatic checkout switch 29 is acquired, and the enable / disable of the stop function and the automatic checkout function is set in a specific register of the main control unit 41 (Sa6).

  Next, it is determined whether or not the RAM parity calculated in step Sa5 is 0 (Sa7). If the power interruption interrupt process (main) is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in step Sa7, the RAM is stored in the RAM of the main control unit 41. In this case, it is determined whether or not the setting key switch 37 is ON (Sa31). If the setting key switch 37 is ON, the random number initial setting stored in the program management area is read. After executing the random number circuit setting process (Sa25), the random number circuit abnormality inspection process for inspecting the presence or absence of an operation abnormality in the random number generation circuit 42 is performed (Sa26).

  After the random number circuit abnormality inspection process in the step of Sa26, it is determined whether or not the random number generation circuit 42 is abnormal, that is, whether or not the random number circuit is abnormal (Sa27a). Whether or not the random number circuit is abnormal is determined by whether or not an error code indicating a random number circuit abnormality is set. If it is determined in step Sa27a that the random number is abnormal, an error command indicating a random circuit error is set in the specific command transmission buffer and transmitted to the sub-control unit 91 (Sa22). (Sa23), the process proceeds to error processing, that is, a RAM abnormal error state.

  If it is determined in step Sa27a that the random number is not abnormal, it is determined whether or not the front door 1b is open based on the detection signal from the door open detection switch (Sa27b).

  When it is determined in step Sa27b that the front door 1b is not open, that is, when it is determined that the front door 1b is in the closed state (closed state), the setting key switch is in the ON state but the RAM is initialized (initialization 1). ) An error command indicating that RAM cannot be cleared is set in the normal command transmission buffer and transmitted to the sub-control unit 91 (Sa27c). An error command indicating that RAM cannot be cleared may be set in the special command transmission buffer.

  Further, a setting door closed state flag indicating that the setting key switch is ON but the front door 1b is not open is set (Sa27d), and the process proceeds to Sa16. When the door closing state flag at the time of setting is set, as will be described later, the progress of the game control is stopped and disabled at a predetermined timing.

  Thus, in Sa27b, when the power switch 39 is turned from OFF to ON (when the power is turned on), a detection signal for specifying that the setting key switch 37 is ON is output (hereinafter, specified) When the open / closed state of the front door 1b at the time of the operation state is determined and it is determined that the front door 1b is not in the open state, it is regarded as an illegal act and the RAM is not cleared (initialization 1). And it is not controlled to the setting change state.

  Further, as described in FIG. 2, the door opening detection switch 25 and the power supply box 100 on which the setting key switch 37, the reset / setting switch 38, and the power switch 39 for performing the setting change operation are respectively provided. Since it is provided on different side surfaces in the housing 1a, the difficulty of performing an illegal act on both the door opening detection switch 25 and the power supply box 100 is increased.

  Furthermore, an illegal act may be considered in which the same detection signal as that in the open state is output by the door open detection switch 25 while the front door 1b is closed with respect to the housing 1a. However, as described above, a reflective optical sensor is used as the door opening detection switch 25. For this reason, in order to perform the above fraudulent act, for example, it is difficult to remove the reflecting member. Further, since it can be visually recognized whether or not the reflecting member has been removed, it is possible to easily grasp that an illegal act has been performed. Therefore, it is possible to prevent an illegal act such that the door open detection switch 25 outputs the same detection signal as in the open state while the front door 1b is closed with respect to the housing 1a.

  On the other hand, when it is determined in step Sa27b that the front door 1b is in the open state, initialization 1 (initializing all storage areas except the used stack area among the RAM storage areas of the main control unit 41). After executing so-called RAM clear (Sa27e), a setting start command is set in the specific command transmission buffer and transmitted to the sub-control unit 91 (Sa28). Next, the interruption is permitted (Sa29), and the setting change processing, that is, the setting change state is entered. The setting change process continues until the setting key switch 37 is turned off regardless of the open / closed state of the front door 1b. That is, once the process is shifted to the setting change process, the setting change process is maintained regardless of the open / closed state of the front door 1b until the setting key switch 37 is turned OFF and the setting end condition is satisfied. For this reason, after the power switch 39 and the setting key switch 37 are properly operated and not set in an unauthorized manner and controlled to the setting change state, the door opening detection switch is touched by mistake during the setting change. For example, even if it is erroneously detected that the front door 1b is in the closed state, the setting change state can be maintained and the setting can be changed reliably.

  If the setting key switch 37 is OFF in the step of Sa31, an error code indicating RAM abnormality is set in the register (Sa32), an error command indicating RAM abnormality is set in the specific command transmission buffer, and the sub-control unit 91 is set. In response to the transmission (Sa33), the interrupt is permitted (Sa34), and the process proceeds to an error process, that is, a RAM abnormal error state.

  If the RAM parity is 0 in step Sa7, it is further determined whether or not the destructive diagnosis data is normal (Sa8). If power interruption interrupt processing (main) is performed normally, the data for destruction diagnosis should have been set. If the data for destruction diagnosis is not normal in step Sa8 (data for destruction diagnosis is power interruption) Since the RAM data of the main control unit 41 is not normal also in the case other than 5A (H) stored at the time), if the setting key switch 37 is ON when the process proceeds to step Sa31, the random number circuit setting is performed. The process (Sa25) and the random number circuit abnormality inspection process (Sa26) are sequentially performed. If the random number circuit is abnormal, the interrupt is permitted (Sa23) after the error command indicating the random number circuit abnormality is transmitted (Sa22), and an error occurs. Transition to processing.

  On the other hand, if the random number circuit is not abnormal, the process proceeds to Sa27b, and when it is determined that the front door 1b is in an open state, after executing initialization 1 (Sa27e), a setting start command is sent to the sub-control unit 91. After the transmission setting (Sa28), the interrupt is permitted (Sa29) and the process proceeds to the setting change process. On the other hand, when it is determined that the front door 1b is not open, an error command indicating that the RAM cannot be cleared is issued. Transmission is set (Sa27c), a setting door closed state flag indicating that the front door 1b is not in an open state is set (Sa27d), and the process proceeds to Sa16. If the setting key switch 37 is OFF in step Sa31, an error code indicating a RAM abnormality is set (Sa32), an error command indicating a RAM abnormality is transmitted (S33), and then an interrupt is permitted (Sa34). ), Go to error handling.

  If it is determined in step Sa8 that the destruction diagnosis data is normal, the RAM data of the main control unit 41 is normal, so the destruction diagnosis data is cleared (Sa9), and the RAM of the main control unit 41 is cleared. After initializing 3 to initialize the non-saved work, the unused area and the unused stack area (Sa10), it is determined whether the setting key switch 37 is ON (Sa11), and the setting key switch 37 is turned ON. If so, the random number circuit setting process (Sa25) and the random number circuit abnormality inspection process (Sa26) are sequentially performed. If the random number circuit is abnormal, the interrupt is permitted after the transmission of the error command indicating the random number circuit abnormality (Sa22). (Sa23), and the process proceeds to error processing. On the other hand, if the random number circuit is not abnormal, the process proceeds to Sa27b, and when it is determined that the front door 1b is in an open state, after executing initialization 1 (Sa27e), a setting start command is sent to the sub-control unit 91. After the transmission setting (Sa28), the interrupt is permitted (Sa29) and the process proceeds to the setting change process. On the other hand, when it is determined that the front door 1b is not open, an error command indicating that the RAM cannot be cleared is issued. Transmission is set (Sa27c), a setting door closed state flag indicating that the front door 1b is not in an open state is set (Sa27d), and the process proceeds to Sa16.

  If the setting key switch 37 is OFF in the step of Sa11, the same random number circuit setting process (Sa13) as the step of Sa25 and the same random number circuit abnormality inspection process (Sa14) as the step of Sa26 are executed, and whether or not the random number circuit is abnormal. Is determined (Sa15).

  If it is determined in step Sa15 that the random number circuit is abnormal, an error command indicating the random number circuit abnormality is set in the specific command transmission buffer, and transmitted to the sub-control unit 91 (Sa22). Permitted (Sa23), the process proceeds to error processing, that is, a RAM abnormal error state.

  If it is determined in step Sa15 that there is no abnormality in the random number circuit, each register is restored to the state before power interruption, that is, the state stored in the stack (Sa16), and the return command is stored in the specific command transmission buffer. It is set and transmitted to the sub-control unit 91 (Sa17). Then, it is determined whether or not the random number value is latched based on the value of the random number latch flag register (Sa18). If the random number value is not latched, the process proceeds to step Sa20, and if the random number value is latched, Numeric data stored in a predetermined random value register is read (Sa19), and the process proceeds to step Sa20. When numerical data is read from the random value register in step Sa19, the random number latch flag register is cleared, and new numerical data is accepted. In the step of Sa19, although the numerical data is read, the read numerical data is not used, but is read as a dummy so that new numerical data can be taken in according to the operation of the start switch 7. is there.

  In step Sa20, the return command is set in the specific command transmission buffer, transmitted to the sub-control unit 91, and then interrupts are permitted (Sa21). Return to.

  In the error processing described above, an error code is displayed on the game auxiliary display 12 and it is determined whether or not the error code is an error code indicating a RAM abnormality error or a random number circuit abnormality, and a RAM abnormality error or a random circuit abnormality is indicated. If it is an error code, the process proceeds to a loop process that does not perform any process. On the other hand, if it is determined that the error code is not an error code indicating a RAM abnormality error or an error code indicating a random number circuit error, an error state occurs. An error command indicating the type is set in the normal command transmission buffer and transmitted to the sub-control unit 91.

  Next, it is determined whether or not the operation of the reset / setting switch 38 is detected. If the operation of the reset / setting switch 38 is not detected, it is further determined whether or not the operation of the reset switch 23 is detected. If the operation of the reset switch 23 is not detected, the process returns to step Sb5. That is, the game waits in a state where the progress of the game is impossible until the operation of the reset / setting switch 38 or the reset switch 23 is detected.

  When the operation of the reset / setting switch 38 is detected or when the operation of the reset switch 23 is detected, the error code stored in the register is cleared and the display state of the game auxiliary display 12 is changed. In step Sb1, the display state saved in the stack is restored, an error command indicating that the error state is released is set in the normal command transmission buffer, and the process returns to the original processing. The error command is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  As described above, in the error processing, if the error processing is not due to the RAM abnormality or the random number circuit abnormality, the reset / setting switch 38 or the reset switch 23 is operated to return to the original processing even when the error state is canceled. However, in the case of error processing due to RAM abnormality or random number circuit abnormality, even if the reset / setting switch 38 or the reset switch 23 is operated, the error state is canceled and the original state is not restored.

  Further, in the error processing, in response to the setting door closing state flag or the confirmation time door closing state flag to be described later being set, a corresponding error code is displayed on the game auxiliary display 12 and set. It is notified that an abnormality has occurred such that the front door 1b is not in an open state despite the key switch 37 being turned on.

  FIG. 7 is a flowchart showing the control content of the setting change process executed by the main control unit 41.

  In the setting change process, first, the setting value stored in the RAM setting value work of the main control unit 41 is read out, and the read value is set as a display value (Sc1), and the display value can be set within a range (1-6). ) It is determined whether or not it is outside (Sc2). If the display value is within the settable range, the process proceeds to step Sc4. If the display value is outside the settable range, the display value is corrected to 1 and Sc4 is set. Go to the step.

  In the step of Sc4, after the display value is displayed on the setting value display 24, the operation waits for detection of the operation of the reset / setting switch 38 and the start switch 7 (Sc5, Sc6). In the step of Sc5, the reset / setting switch When 38 on is detected, the rising edge indicating the rising of the operation switch is cleared (Sc7), the display value is incremented by 1 (Sc8), and the process returns to the step Sc2. The rising edge is edge data indicating that the corresponding operation switch is changed from OFF to ON when the corresponding operation switch is changed from OFF to ON. Thus, for example, the rising edge of the start switch 7 refers to edge data indicating that the start switch 7 has changed from OFF to ON. On the other hand, the falling edge is edge data indicating that the corresponding operation switch has changed from ON to OFF when the corresponding operation switch has changed from ON to OFF.

  When the start switch 7 is detected to be on in the step of Sc6, the rising edge is cleared (Sc9), the value displayed on the set value display 24 is updated to 0 (Sc10), and the setting key Wait until the switch 37 is turned off (Sc11).

  If it is determined in step Sc11 that the setting key switch 37 is OFF, the display value is stored in the set value work (Sc12), a game state command is generated, and set in the command transmission buffer (Sc13). The gaming state command set in the step of Sc13 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  In the step of Sc14, it is determined whether or not a setting door closed state flag or a disabling flag for disabling the game is set. When it is determined in the step of Sc14 that the flag is not set, the process directly proceeds to game processing. On the other hand, when it is determined in the step of Sc14 that the flag is set, the set flag is cleared (Sc15), and the process proceeds to the game process. As a result, once the set door closing state flag or the disablement flag is set, the flag is not cleared until the setting change state is entered, so that the game can be disabled.

  FIG. 8 is a flowchart showing the control contents of the game process executed by the main control unit 41.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), and a game end process (Sd6) are sequentially executed. When the end-time process ends, the process returns to the BET process again.

  In the BET process in the step of Sd1, the process waits in a state where a bet number can be set, and a process for starting a game when a specified number of bets is set according to the gaming state and the start switch 7 is operated is executed. .

  In the internal lottery process in the step Sd2, a process is performed for determining whether or not the above winning combination is permitted based on the numerical data latched simultaneously with the start of the game by the detection of the start switch 7 in the step Sd1. In the internal lottery process, a winning flag is set in the RAM of the main control unit 41 based on each lottery result.

  In the reel rotation process in the step of Sd3, the process of rotating each reel 2L, 2C, 2R and the operation of the corresponding reel 2L, 2C, 2R in response to the operation of the stop switch 8L, 8C, 8R detected by the player are detected. A process for stopping the rotation is executed.

  In the winning determination process in the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  In the payout process in step Sd5, when it is determined in step Sd4 that a winning has occurred, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd6, a process of setting a gaming state in preparation for the next game is executed.

  In the game process, a command is generated according to the progress control of the game and set in the normal command transmission buffer, so that the command set for the sub-control unit 91 in the subsequent timer interrupt process (main) Is to be sent.

  9 to 11 are flowcharts showing the control contents of the BET process executed by the main control unit 41 in step Sd1.

  In the BET process, first, the value of the BET counter in which the value of the betting number is stored in the RAM of the main control unit 41 is cleared (Se1), and a prescribed number corresponding to the gaming state (in this embodiment, regardless of the gaming state). 3) is set in the RAM of the main control unit 41 (Se2), and the game is a replay game based on whether or not the replay game flag indicating that the game is a replay game is set in the RAM of the main control unit 41. Whether or not (Se3).

  If it is determined in step Se3 that the game is a replay game, a BET command indicating that 3 bets have been added is set in the normal command transmission buffer (Se4), and the value of the BET counter is set to 1. Addition (Se5), with reference to the prescribed number of bets set in the RAM of the main control unit 41, whether or not the value of the BET counter is the prescribed number, that is, the number of bets serving as a game start condition is set. If the value of the BET counter is not the specified number, the process returns to the step of Se5. If the value of the BET counter is the specified number, the insertion prohibition flag indicating that the medal cannot be inserted is controlled by the main control. Set in the RAM of the unit 41 (Se7), and proceed to the step of Se12. The BET command set in step Se4 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  If it is determined in the step Se3 that the game is not a replay game, the setting before waiting for input is performed (Se8), and the process proceeds to the step Se9. In the setting before waiting for insertion, the insertion disable flag set in the RAM of the main control unit 41 is cleared, and a medal can be inserted.

  In the step of Se9, it is determined whether or not the value of the BET counter is a specified number, that is, whether or not the number of bets serving as a game start condition is set. Proceeding to the step, if the value of the BET counter is a specified number, it is further determined whether or not any of the switches has been turned OFF (Se10). In the step of Se10, it is determined whether or not any of the switches has been turned off based on whether or not a falling edge indicating the falling of any of the switches is set. Further, since the falling edge is set only when any switch is turned off and all the switches are turned off, in the step of Se10, it is determined whether any switch is turned off or not. In addition, it is also determined whether or not other switches are OFF.

  If it is determined in step Se10 that none of the switches have changed to OFF, or if any switch has changed to OFF but is still ON, the process proceeds to step Se14. If any of the switches changes to OFF and it is determined that all the switches are OFF, the falling edge is cleared (Se11) and the process proceeds to Se12.

  In the step of Se12, it is determined whether or not numerical data is latched based on the value of the random number latch flag register, that is, whether or not numerical data is taken into the random value register, and if the numerical data is not latched. Proceeding to the step of Se14, if the numerical data is latched, the numerical data is read from the random value register (Se13), and the process proceeds to the step of Se14. Note that when the numerical data is read from the random number value register in the step of Se13, the random number latch flag register is cleared, and the acquisition of new numerical data is permitted. In the step of Se13, although the numerical data is read, the read numerical data is not used, but is read as a dummy so that new numerical data can be taken in according to the operation of the start switch 7. is there. For this reason, although the number of bets serving as a game start condition is set, the switches other than the start switch 7 are operated, and the start switch 7 is in the state where the operation of the start switch 7 is invalidated. Even if numerical data is latched because it has been operated and new numerical data is not imported, all switches are turned off and latched when the start switch 7 is activated. The numerical data that has been read is read as a dummy, and the numerical data can be newly latched at the timing when the start switch 7 is operated thereafter.

  In step Se14, it is determined whether or not an error code is set in the register, that is, whether or not an error is detected. If an error code is set, the process proceeds to the error processing described above.

  If no error code is set in the step of Se14, it is determined whether or not a medal can be inserted based on whether or not the insertion prohibition flag is set in the RAM of the main control unit 41 (Se15). When it is determined in step Se15 that the medal can be inserted, the flow path switching solenoid 30 is turned on, and the medal can be inserted using the medal flow path as a path on the hopper tank side. (Se16), the process proceeds to step Se18, and if it is determined that the medal cannot be inserted, the flow path switching solenoid 30 is set to the off state, and the medal flow path is the path on the medal payout exit 9 side. As a result, the insertion of a new medal is prohibited (Se17), and the process proceeds to Step Se18.

  In step Se18, it is determined whether or not the setting key switch 37 is on. If the setting key switch 37 is on, the front door 1b is open based on the detection signal from the door opening detection switch. Whether or not (Se18a).

  If it is determined in step Se18a that the front door 1b is not open, that is, if it is determined that the front door 1b is in the closed state (closed state), the setting key switch is ON but the front door 1b is not open Since it can be considered that there has been a state of inconvenience or fraudulent behavior, a door closing state flag at the time of confirmation indicating that it is not possible to shift to the setting confirmation process described later is set (Se18b), and the setting value cannot be transferred to the setting confirmation process Is set in the normal command transmission buffer, transmitted to the sub-control unit 91 (Se18c), and the process proceeds to Sa22. When the confirmation door closed state flag is set, a corresponding error code is displayed on the game auxiliary display 12 in the error processing described above. When the operation of the reset / setting switch 38 or the operation of the reset switch 23 is detected, the door closing state flag at the time of confirmation is cleared and the error code display is ended.

  On the other hand, when it is determined in step Se18a that the front door 1b is in the open state, that is, it is determined that the front door 1b is in the open state (open state), it is determined whether or not the value of the BET counter is 0 (Se19). ). In order to shift to the setting confirmation process, it is a condition that YES is determined in Se18 and YES is determined in Se19. For this reason, you may make it perform the determination process of Se18a, after determining with YES in Se18 and determining with YES in Se19.

  If the value of the BET counter is 0 in the step of Se19, the confirmation start command is set in the normal command transmission buffer (Se20), and the setting confirmation process (Se21), that is, the setting confirmation state is entered. The confirmation start command set in step Se20 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main). Moreover, after the setting confirmation process in the step of Se21 is completed, the process returns to the step of Se9.

  In the setting confirmation process, first, the display value of the payout display 13 is saved, the setting value currently set is acquired from the setting value work of the RAM 41c, and the acquired setting value is displayed on the payout display 13. Thereafter, the control waits until the setting key switch 37 is turned off. When the setting key switch 37 is turned off, the display value of the payout display 13 previously saved is restored, and then a confirmation end command is sent to the normal command transmission buffer. To complete the setting confirmation process. The set confirmation end command is transmitted to the sub CPU 91a in the subsequent timer interrupt process (main).

  If the setting key switch 37 is not on in step Se18, or if the value of the BET counter is not 0 in step Se19, the process proceeds to step Se22a to determine whether the door closing state flag is set. judge. When it is determined that the door closing state flag at the time of setting is set, the process proceeds to step Se22b, and it is determined whether or not a currently valid specific operation has been detected. The detection of the specific operation currently effective means detection of the inserted medal sensor 31, detection of the single BET switch 5, detection of the MAXBET switch 6, detection of the settlement switch 10, and the like.

  It should be noted that the specific operation is effectively detected until the operation to the start switch 7 described later is detected even when the set door closed state flag is set, and the corresponding processing is performed. (For example, processing when it is determined YES in each of Se22d, Se39, Se47, and Se56).

  When it is determined in Se22b that a currently valid specific operation has been detected, the process proceeds to step Se22c, and the disabling flag for disabling operation by stopping the progress of the game by disabling the operation of the start switch 7 Set. On the other hand, when it is determined at Se22a that the set door closing state flag is not set, when it is determined at Se22b that a currently valid specific operation is not detected, and when the disabling flag is set at Se22c , Go to the step of Se22d.

  In Se22d, it is determined whether or not the inserted medal sensor 31 has detected the passage of the inserted medal, that is, the presence or absence of the inserted medal flag indicating that the passage of the inserted medal has been detected. If the passage of the inserted medal is not detected in the step of Se22d, the process proceeds to the step of Se33, and if the passage of the inserted medal is detected, the inserted medal flag is cleared (Se23) and is inserted into the RAM of the main control unit 41. It is determined whether or not a medal can be inserted based on whether or not a disabling flag is set (Se24). If the medal cannot be inserted, the process proceeds to Step Se33.

  If the medal can be inserted in step Se24, the prescribed number of bets set in the RAM of the main control unit 41 is referred to and it is determined whether or not the value of the BET counter is the prescribed number (Se20). ) If the value of the BET counter is not a specified number, a BET command indicating that the bet number is incremented by 1 is set in the normal command transmission buffer (Se26), and the value of the BET counter is incremented by 1 (Se27) It is determined whether or not the value of the BET counter is a specified number, that is, whether or not the number of bets serving as a game start condition has been set (Se28). If the value of the BET counter is not the specified number, the process returns to Step Se9. . The BET command set in step Se <b> 26 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  Further, if the value of the BET counter is the specified number in the step of Se28, that is, if the betting number as the game start condition is set, the process returns to the step of Se12 and the betting number as the game start condition is set. If the numerical data is latched before being performed, the numerical data is read in step Sa13, and new numerical data can be taken in. For this reason, since the number of bets serving as a game start condition is not set and the start switch 7 is operated in a state where the operation of the start switch 7 is invalidated, the numerical data is latched, and the new numerical data Even when the take-in is prohibited, a predetermined number of bets are set as a game start condition, and the numerical data latched when the operation of the start switch 7 is validated is read as a dummy. The numerical data can be newly latched at the timing when the start switch 7 is operated thereafter.

  If the value of the BET counter is a specified number in the step of Se25, a credit command indicating the current credit counter value is set in the normal command transmission buffer (Se29), and the credit value is stored in the RAM of the main control unit 41. 1 is added to the value of the credit counter (Se30), and it is determined whether or not the value of the credit counter is the upper limit value 50 (Se31). If the value of the credit counter is not 50, the process proceeds to Step Se9. Returning, if the value of the credit counter is 50, the insertion impossible flag is set in the RAM of the main control unit 41 (Se32), and the process returns to the step of Se9. The credit command set in the step of Se29 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  In step Se33, it is determined whether or not an operation of the start switch 7 is detected, that is, whether or not a rising edge indicating a rising edge of the start switch 7 is set. Further, the rising edge is set only when any switch is turned on and all the switches are turned off. Therefore, in the step of Se33, in addition to whether any switch is turned on. Whether or not the other switch is OFF is also determined.

  If it is determined that the operation of the start switch 7 is not detected in the step of Se33, or if another switch for which the start switch 7 is operated is also operated, the process proceeds to the step of Se39, where the start switch 7 If the operation is effectively detected, the rising edge is cleared (Se34), the specified number of bets set in the RAM of the main control unit 41 is referred, and the value of the BET counter is the specified number. That is, it is determined whether or not the number of bets serving as a game start condition is set (Se35a).

  If the value of the BET counter is not the specified number in the step of Se35a, the process returns to the step of Se9, and if the value of the BET counter is the specified number, the process proceeds to the step of Se35b. In Se35b, it is determined whether or not the disabling flag is set. Normally, the setting change operation cannot be performed unless the front door 1b is opened. When it is determined in Se35b that the disabling flag is set, the front door 1b is displayed when the setting change operation is performed. Is in an abnormal state as if it was in a closed state, and therefore the process proceeds to a loop process in which no process is performed. Thereby, the game is disabled until the setting change state is entered. For this reason, it is easily specified by the game hall manager or other players that the illegal act has been performed. As a result, fraud can be suppressed by increasing the risk of performing fraud.

  Further, regardless of the progress status of the game immediately before being disabled, the operation of the start switch 7 when the disable flag is set is invalidated, and therefore disabled when the start switch 7 is operated. The process of determining whether or not the flag is set is performed, and the process proceeds to the loop process when the disablement flag is set, so that the progress of the game thereafter can be disabled.

  When the game is disabled, for example, when the power is turned on again without turning the setting key switch to the ON state, the process proceeds to the loop process as described in Sa21 and the subsequent steps in FIG. For this reason, the immobilization cannot be canceled. On the other hand, when the game is disabled, for example, when the front door 1b is opened and the setting key switch is turned on and the power is turned on again, as described in and after Sa29 in FIG. The process is shifted to the setting change process of FIG. 7, and the immobilization flag is deleted in Sc15, so that the immobilization can be canceled. As described above, the immobilization of the game is canceled by properly shifting to the setting change state. Therefore, a person who has performed a fraudulent act cannot easily release the disabled state of the game, but a person who can operate the setting key switch with the front door 1b opened (for example, a game management) If it is a person), the immobilization can be canceled easily and quickly.

  On the other hand, when it is determined in Se35b that the disabling flag is not set, the process proceeds to step Se36, and the value of the random number storage work is set as a random value for internal lottery in the lottery work (Se36) and cannot be inserted. The flag is set in the RAM of the main control unit 41, the flow path switching solenoid 30 is turned off, and the insertion of a new medal is prohibited using the medal flow path as a path on the medal payout exit 9 side (Se37). Setting at the start is performed (Se38). Then, after the step of Se38, the BET process is terminated and the process returns to the flowchart of FIG.

  In the step of Se39, it is determined whether or not the operation of the single BET switch 5 is detected, that is, whether or not the rising edge indicating the rising of the single BET switch 5 is set. If the operation of the single BET switch 5 is not detected in the step of Se39, the process proceeds to the step of Se47, and if the operation of the single BET switch 5 is detected, the rising edge is cleared (Se40), and the main controller 41 Referring to the prescribed number of bets set in the RAM, it is determined whether or not the value of the BET counter is the prescribed number (Se41). If the value of the BET counter is a specified number in the step of Se41, the process returns to the step of Se9. If the value of the BET counter is not the specified number, it is determined whether or not the value of the credit counter is 0 (Se42). If the counter value is 0, the process returns to step Se9. If the value of the credit counter is not 0 in the step of Se42, a BET command indicating that 1 is added to the bet number is set in the normal command transmission buffer (Se43), and 1 is subtracted from the value of the credit counter (Se44). Then, the value of the BET counter is incremented by 1 (Se45), and it is determined whether or not the value of the BET counter is a specified number, that is, whether or not the number of bets serving as a game start condition is set (Se46). If the value of the counter is not a specified number, the process returns to step Se9. The BET command set in the step of Se43 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  Further, if the value of the BET counter is the prescribed number in the step of Se46, that is, if the betting number that is the game start condition is set, the process returns to the step of Se12 and the betting number that is the game start condition is set. If the numerical data is latched before being performed, the numerical data is read in step Sa13, and new numerical data can be taken in. For this reason, since the number of bets serving as a game start condition is not set and the start switch 7 is operated in a state where the operation of the start switch 7 is invalidated, the numerical data is latched, and the new numerical data Even when the take-in is prohibited, a predetermined number of bets are set as a game start condition, and the numerical data latched when the operation of the start switch 7 is validated is read as a dummy. The numerical data can be newly latched at the timing when the start switch 7 is operated thereafter.

  In the step of Se47, it is determined whether or not the operation of the MAXBET switch 6 is detected, that is, whether or not the rising edge indicating the rising of the MAXBET switch 6 is set. If the operation of the MAXBET switch 6 is not detected in the step of Se47, the process proceeds to the step of Se61. If the operation of the MAXBET switch 6 is detected, the rising edge is cleared (Se48) and the RAM of the main control unit 41 is stored. With reference to the set number of bets, it is determined whether or not the value of the BET counter is a specified number (Se49). If the value of the BET counter is the specified number in the step of Se49, the process proceeds to the step of Se53, and if the value of the BET counter is not the specified number, it is determined whether or not the value of the credit counter is 0 (Se50), If the value of the credit counter is 0, the process proceeds to step Se53. If the value of the credit counter is not 0 in the step of Se50, 1 is subtracted from the value of the credit counter (Se51), 1 is added to the value of the BET counter (Se52), and the process returns to the step of Se49. In the step of Se53, it is determined whether or not the BET counter has been added. If the BET counter has not been added, the process returns to the step of Se9, and if the BET counter has been added, the bet number is added by the added number. The BET command indicating that it has been set is set in the normal command transmission buffer (Se54), and the process proceeds to Se55. The BET command set in step Se54 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main).

  In the step of Se55, it is determined whether or not the value of the BET counter is a specified number, that is, whether or not the bet number as a game start condition is set. If the value of the BET counter is not the specified number, the step of Se9 Return to. Further, if the value of the BET counter is the prescribed number in the step of Se55, that is, if the betting number as the game start condition is set, the process returns to the step of Se12 and the betting number as the game start condition is set. If the numerical data is latched before being performed, the numerical data is read in step Sa13, and new numerical data can be taken in. For this reason, since the number of bets serving as a game start condition is not set and the start switch 7 is operated in a state where the operation of the start switch 7 is invalidated, the numerical data is latched, and the new numerical data Even when the take-in is prohibited, a predetermined number of bets are set as a game start condition, and the numerical data latched when the operation of the start switch 7 is validated is read as a dummy. The numerical data can be newly latched at the timing when the start switch 7 is operated thereafter.

  In the step of Se56, it is determined whether or not the operation of the settlement switch 10 has been detected, that is, whether or not a rising edge indicating the rising of the settlement switch 10 has been set. If the operation of the settlement switch 10 is not detected in the step of Se56, the process returns to the step of Se9, and if the operation of the settlement switch 10 is detected, the rising edge is cleared (Se57) and stored in the RAM of the main control unit 41. Based on whether or not the replay game flag is set, it is determined whether or not the game is a replay game (Se58). If the game is a replay game, the process returns to step Se9. If the game is not a replay game in the step of Se58, it is determined whether or not the value of the BET counter is 0 (Se59). If the value of the BET counter is 0, the process proceeds to the step of Se61 and the value of the BET counter is 0. Otherwise, a bet amount settlement flag indicating that the already set bet amount is to be settled is set in the RAM of the main control unit 41 (Se60), and the process proceeds to Step Se61. In step Se61, the hopper motor 34 is driven to pay out medals corresponding to the value stored in the credit counter or BET counter, that is, medals stored as credits or medals used for setting the number of bets. Checkout processing is performed in which the return control is performed. Then, after the settlement process in the step of Se61, the input impossible flag set in the RAM of the main control unit 41 is cleared (Se62), and the process returns to the step of Se9.

  Next, the control of the effect performed by the sub-control unit 91 based on the command transmitted from the main control unit 41 to the effect control board 90 will be described.

  When the sub control unit 91 receives a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  In the timer interrupt process (sub), the sub-control unit 91 determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub-control unit 91 is the earliest. The control pattern table stored in the ROM 91b is referred to based on the command received in the stage, and the liquid crystal display 51, effect effect LED 52, speakers 53, 54, reel LED 55, etc. are controlled based on the control contents registered in the control pattern table. Output control of various production devices is performed.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. Control patterns of these effect devices are registered, and when the sub-control unit 91 receives a command, the sub-control unit 91 stores the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. Among these, the control pattern corresponding to the type of the received command is referred to, and the output control of the rendering device is performed based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub-control unit 91 receives a new command during the execution of an effect triggered by the reception of a certain command, the sub-control unit 91 stops the effect based on the control pattern being executed, and sets the newly received command. An effect based on the corresponding control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is received unless the received new command is not a command that triggers a new production. An effect based on the command is executed.

  In particular, in the present embodiment, when the betting number setting operation is performed during the execution of the effect, that is, when the sub-control unit 91 receives a BET command indicating that the betting number has been set, The production is to be canceled. For this reason, if the player wants to proceed to the next game rather than seeing the production to the end, the production is canceled and the next game can be started. There is no. Further, when a credit or betting amount adjustment operation is performed during the performance, that is, after the sub-control unit 91 receives a game state command indicating the end of the game, it receives an internal winning command indicating the start of the game. When the payout start command is received before, the effect being executed is stopped. Credits and bets are settled when the game is finished. In such a case, the production is continued unnecessarily even though there is an intention to finish the game by ending the performance being executed. It is designed not to be overwhelmed.

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. The selection rate of the effect pattern is registered in the effect table stored in the ROM 91b, and when the sub control unit 91 receives the internal winning command, the sub control unit 91 stores the effect pattern in the effect table according to the result of the internal lottery indicated by the internal winning command. With reference to the registered selection rate, one of the effect patterns is selected from a plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game. Even if the same command is received, a different control pattern is selected depending on the effect pattern selected when the internal winning command is received. As a result, different effects may be performed depending on the effect pattern.

  In addition, when receiving an error command from the main control unit 41, the sub control unit 91 performs notification processing according to the type of error specified from the error command. For example, when an error command indicating that the RAM cannot be cleared is received, the front door 1b is not in the open state even though the power switch 39 is turned on from OFF and the setting key switch 37 is turned on to enter the specific operation state. Notifying that the setting is not changed and the RAM is not cleared (in the liquid crystal display 51, a message such as “setting change and RAM cannot be cleared!” Is displayed, and the first abnormal sound is generated from the speakers 53 and 54). Is done. Further, when an error command indicating that confirmation is impossible is received, the front key 1b is not in an open state even though the setting key switch 37 is turned on and the specific operation state is entered, and it is not possible to proceed to setting confirmation processing (liquid crystal display In the device 51, a message such as “Setting confirmation impossible!” Is displayed, and a second abnormal sound is generated from the speakers 53 and 54.

  In the present embodiment, the main control unit 41 sends a setting start command to the sub-control unit 91 when the front door 1b is opened and the state setting key switch 37 is activated as shown in FIG. This is transmitted to notify the start of the setting change state and shift to a setting change state in which the setting value can be changed. In the setting change state, the set value can be arbitrarily selected until the start switch 7 is operated. However, when the start switch 7 is operated, the set value selected at that time is fixed. After that, the setting confirmation state in which the setting value cannot be changed is entered. In this state, the setting key switch 37 is turned off to end the setting changing state, and a game state command is transmitted to the sub-control unit 91 to change the setting. Notify the end of the state.

  On the other hand, the sub control unit 91 is notified of the start of the setting change state by the setting start command, thereby clearing the game history data, setting the game history data that can be viewed by the player, and viewing the setting change history. In other words, the management mode is controlled so that the management information on the sub-control unit 91 side managed by the game store can be accessed. Then, the manager mode is ended when the end of the setting change state is notified by the game state command. When the administrator mode is controlled, a predetermined administrator mode screen is displayed on the liquid crystal display 51. In this administrator mode screen, for example, game history data can be cleared or viewed by the player. The game history data can be set and the setting change history can be browsed.

  Even if the set value is confirmed in the setting change state, no notification is given from the main control unit 41 to the sub-control unit 91, and the sub-control unit 91 is configured after the set value is confirmed on the main control unit 41 side. However, until the end of the setting change state is notified by the game state command, it is continuously controlled to the administrator mode, and the power is turned on again after the setting value is confirmed in the setting changing state. As a result, the management information can be accessed without reverting to the state before the set value is determined.

  Further, the main control unit 41 confirms when the setting key switch 37 is turned on after the game is over and the bet amount is not set as shown in FIG. 13 with the front door 1b opened. A start command is transmitted to the sub-control unit 91 to notify the start of the setting confirmation state and shift to a setting confirmation state in which the setting value can be confirmed. The setting confirmation state ends when the setting key switch 37 is turned off, and the confirmation confirmation command is transmitted to the sub-control unit 91 to notify the end of the setting confirmation state.

  Then, even when the start of the setting confirmation state is notified by the confirmation start command, the sub control unit 91 uses the management information on the sub control unit 91 side managed by the amusement store as in the case of receiving the setting start command. Control the administrator mode to be accessible. The administrator mode ends when the end of the setting confirmation state is notified by the confirmation end command.

  The setting key switch 37 is a switch that can be turned ON / OFF by inserting and rotating the key, but the normal key is possessed by the store clerk and can be arbitrarily set by the player. 37 cannot be operated. That is, only when the setting key switch 37 that cannot be arbitrarily operated by the player is operated, the manager mode is controlled so that the management information on the sub-control unit 91 side managed by the game store can be accessed.

  As described above, in this embodiment, not only when the main control unit 41 is controlled to the setting change state but also when the main control unit 41 is controlled to the setting confirmation state, the administrator mode is controlled. The management information can be accessed without shifting to the changed state. In particular, even if the setting change state is not entered unless the power is turned on again as in this embodiment, it is not necessary to turn off the power just to access the management information. Furthermore, even when the RAM 41c is initialized with the transition to the setting change state as in the present embodiment, it is possible to access the management information while maintaining the stored data in the RAM 41c.

  In this embodiment, when a setting start command or a confirmation start command is received from the main CPU 91a, control is performed in the administrator mode as it is. However, after the setting start command or the confirmation start command is received, For example, the configuration may be such that the administrator mode is controlled only when a certain operation is performed, for example, the MAXBET switch 6 is operated for a certain period of time or more. It is possible to prevent the administrator mode from being controlled even though there is no need to access the.

  As described above, when the main control unit 41 is controlled to the setting change state or the setting confirmation state, the administrator mode screen is displayed. By operating, for example, the stop switches 8L, 8C, 8R on the screen. It is possible to clear game history data, set game history data that can be viewed by the player, and view setting change history.

  In the present embodiment, even if the game history data is cleared, the setting change history data is not cleared. For example, even if the setting change is made illegally, the evidence is surely left. The setting change history data may be cleared together with the clearing of the game history data, or the game history data and the setting change history data may be cleared by separate operations. Good.

  In the present embodiment, a setting change history as an example of management information is stored, and the setting change history can be confirmed in the game shop setting mode. For example, the front door of the slot machine 1 is opened. History (opening time and opening frequency information based on opening of front door) and error occurrence history (error occurrence time, type of error, number of errors), etc. are stored, and in the administrator mode these front doors You may be able to check the release history and error occurrence history.

Next, main effects obtained by the embodiment described above will be described.
(1) In Sa27b of FIG. 6 in the above-described embodiment, when the power switch 39 is turned from OFF to ON (when the power is turned on), a detection signal for specifying that the setting key switch 37 is ON is output. When the open / closed state of the front door 1b at the time of the specific operation state is determined and it is determined that the front door 1b is not in the open state, it is regarded as an illegal act and the RAM is not cleared (initialization 1), and It is not controlled by the setting change state. That is, if the front door 1b is not in an open state, the power switch 39 and the setting key switch 37 cannot be operated and cannot enter a specific operation state. When there is a possibility that an illegal act has been performed without being in the open state, the RAM is not cleared and the setting change state is not controlled. Accordingly, it is possible to reliably prevent the setting change by being controlled to the setting change state by an unauthorized act, and further prevent the RAM from being cleared by an unauthorized act.

  Control to the setting change process is continued until the setting key switch 37 is turned off regardless of the open / closed state of the front door 1b. That is, once the process is shifted to the setting change process, the setting change process is maintained regardless of the open / closed state of the front door 1b until the setting key switch 37 is turned OFF and the setting end condition is satisfied. For this reason, after the power switch 39 and the setting key switch 37 are properly operated and not set in an unauthorized manner and controlled to the setting change state, the door opening detection switch is touched by mistake during the setting change. For example, even if it is erroneously detected that the front door 1b is in the closed state, the setting change state can be maintained and the setting can be changed reliably. For this reason, there is no need for the game hall manager to be bothered by having to turn off the power again to change the setting from the beginning due to an erroneous operation.

  Further, during the BET processing in the above-described embodiment, the open / close state of the front door 1b when the setting key switch 37 enters the operation state in which the detection signal for specifying ON is output in Se18a of FIG. Is determined and it is determined that the front door 1b is not in the open state, it is regarded as an illegal act, and the setting confirmation state is not controlled. In other words, the setting key switch 37 cannot be operated unless the front door 1b is normally open. However, when the setting key switch 37 is turned on, the front door 1b is not open and fraudulent behavior occurs. When there is a possibility that it has been performed, the setting confirmation state is not controlled. Accordingly, it is possible to reliably prevent the setting value from being specified by being controlled to the setting confirmation state by an illegal act.

  Control to the setting confirmation processing is continued until the setting key switch 37 is turned off regardless of the open / closed state of the front door 1b. In other words, the setting confirmation process is maintained regardless of the open / closed state of the front door 1b until the setting key switch 37 is turned OFF after the transition to the setting confirmation process. For this reason, after the setting key switch 37 is properly operated and not set in the setting confirmation state instead of an unauthorized act, the front of the door may be accidentally touched on the door opening detection switch during the setting confirmation. Even if it is erroneously detected that the door 1b is in the closed state, the setting confirmation state can be maintained and the setting confirmation can be reliably performed. For this reason, for example, after the setting key switch 37 is turned off, the amusement hall manager is not caused to be bothered by having the setting key switch 37 turned on again to be in a setting confirmation state. .

  (2) In the above-described embodiment, when it is determined NO in Sa27b of FIG. 6, an error command indicating that RAM cannot be cleared is transmitted in Sa27c, and the sub-control unit 91 is notified that RAM cannot be cleared. At the same time, the set door closed state flag is set in Sa27d, and the corresponding error code is displayed on the game auxiliary display 12. Further, when it is determined YES in Se18 in FIG. 9 and NO is determined in Se18a, an error command indicating that confirmation is not possible is transmitted in Se18c, and it is notified that the set value cannot be confirmed on the sub-control unit 91 side. At the same time, the door closing state flag is set at Se18b and the corresponding error code is displayed on the game auxiliary display 12. In this way, since it is possible to notify that an abnormality has occurred, fraudulent acts can be suppressed.

  (3) According to the above-described embodiment, as described in FIG. 2, the door opening detection switch 25, the setting key switch 37 for performing the setting change operation, the reset / setting switch 38, and the power switch 39 are provided. Since the mounted power supply boxes 100 are respectively provided on different side surfaces in the housing 1a, the difficulty of performing fraud on both the door opening detection switch 25 and the power supply box 100 is increased. It has been.

  (4) In the embodiment described above, if YES is determined in Sa11 or Sa31 in FIG. 6 and NO is determined in Sa27b, the progress of the subsequent game is disabled. For this reason, it is easily specified by the game hall manager or other players that the illegal act has been performed. As a result, fraud can be suppressed by increasing the risk of performing fraud.

  (5) When disabled in the above-described embodiment, as indicated by Sc14 and Sc15 in FIG. 7, it is essential to control the setting change state by shifting to the setting change process. For this reason, the immobilization cannot be easily canceled for a person who has performed an illegal act, whereas the disablement can be easily and quickly canceled by a game hall manager.

  (6) In the above-described embodiment, as indicated by Se22b, Se22c, Se33, and Se35b in FIG. 10, the disable flag is set regardless of the progress of the game immediately before being disabled. Since the operation of the start switch 7 is invalidated, the process for determining whether or not the disable flag is set when the start switch 7 is operated is performed, and the disable disable flag is set. Sometimes, by shifting to the loop process, the progress of the game thereafter can be disabled. For this reason, it is possible to facilitate the processing for disabling and prevent the processing burden from increasing because there is no need to perform special control for disabling. Further, until the start switch 7 is operated, it is not necessary to perform special control for disabling operation, and an increase in processing load can be prevented.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  (1) In the above-described embodiment, even if an error indicating that confirmation cannot be made when it is determined in Se18a of FIG. 9 that the front door 1b is not open, the progress of the game is not disabled, and An example has been described in which the reset / setting switch 38 or the reset switch 23 is released when it is detected. However, the present invention is not limited to this, and when it is determined in Se18a of FIG. 9 that the front door 1b is not in an open state and an error indicating that the confirmation is impossible occurs, the progress of the game is disabled and the setting change process is executed. Accordingly, the error indicating that the confirmation is impossible and the immobilization may be canceled. Thereby, fraudulent acts can be more effectively suppressed.

  (2) In the above-described embodiment, the information for disabling the progress of the game (for example, the setting door closed state flag and the disabling disabling flag) has been described with respect to the example cleared in Sc15 in FIG. However, the present invention is not limited to this as long as it is performed in accordance with the control of the setting change process. For example, it may be cleared by performing initialization 1 of Sa27e in FIG.

  (3) In the above-described embodiment, once the process proceeds to the setting check process, the setting check process is maintained regardless of the open / closed state of the front door 1b until the setting key switch 37 is turned off. However, the present invention is not limited to this, and the setting confirmation process may be terminated when, for example, the front door 1b is closed according to the open / closed state of the front door 1b.

  (4) In the above-described embodiment, when the setting change operation is performed, if the front door 1b is in a closed state and is disabled, the normal operation (open the front door 1b, turn off the power) The example in which the immobilization is canceled when the setting key switch 37 is turned on and the power is turned on to shift to the setting change state has been described. However, the opportunity to cancel the immobilization is not limited to this, and may be a predetermined operation.

  FIG. 14 is a flowchart showing the control content of the startup process (main) in the first modification. Below, only a different part from FIG. 6 is demonstrated. Referring to FIG. 14, when it is determined in Sa27b that front door 1b is not in the open state, that is, in the closed state, an error command indicating that the RAM cannot be cleared is set in the normal command transmission buffer, and sub-control unit 91 is set. (Sa27c ') and the determination process of Sa27d' is repeated until the setting key switch is turned off.

  When it is determined in Sa27d ′ that the setting key switch is in the OFF state, a cancel command indicating that the error has been canceled is set in the normal command transmission buffer and transmitted to the sub-control unit 91 (Sa27e ′). To Sa16. That is, after it is determined in Sa27b that the front door 1b is in the closed state, the game is disabled as long as the setting key switch 37 is in the ON state, and the setting key switch 37 is in the OFF state. Deactivation is released. This makes it impossible for a person who has committed fraud to easily release the disabled game, whereas a person who can operate the setting key switch with the front door 1b open (for example, a game hall If it is an administrator), the immobilization can be canceled easily and quickly.

  (5) In the above-described embodiment, the example in which the game is disabled according to the determination result of Sa27b in FIG. 6 has been described. However, the processing of Sa27b only needs to be performed between when the power is turned on and when the setting change state or initialization 1 is executed, whichever is earlier.

  (6) In the above embodiment, as an example of a gaming machine, a game can be started and a display state can be changed by setting a bet number using medals and credits for one game. A slot machine has been described in which one game is completed when a display result is derived to a variable display device, and a winning can be generated according to the display result of the variable display device.

  However, the gaming machine that embodies the present invention is not limited to such a slot machine, and may be any gaming machine that can change the advantage to the player. As a gaming machine, for example, a game medium (for example, a pachinko ball) is driven into a predetermined game area, and the game medium that has been driven passes (wins) through a start area (for example, a start port) provided in the game area. The display state of the variable display device can be changed, and when the display result of the variable display device becomes a specific display result (for example, a combination of jackpot symbols), a specific game state (big hit state) that is advantageous to the player It may be a pachinko machine that is controlled. In this case, changing the degree of advantage means setting any one of a plurality of types of setting values determined so that the probability of being controlled to a specific gaming state (so-called jackpot) is different. In addition, the variable display condition is established when the variable passes through the start area and a random number is read out. In accordance with the probability specified from the above, it is determined whether or not the specific display result is derived using the random number.

  Here, the configuration corresponding to the “opening / closing body” and “opening / closing state detecting means” when the present invention is applied to a pachinko machine will be described with reference to FIGS. As shown in FIGS. 15 to 18, the pachinko machine includes an outer frame 912 and a main body frame 914. The outer frame 912 is formed in a substantially rectangular shape and is fixed to a so-called island or the like in a game hall. The main body frame 914 is pivotally supported on one side by the outer frame 912, and as shown in FIG. 15, the other side is close to the outer frame 912 (closed state), and as shown in FIGS. The other side is rotatable between an open position (open state) separated from the outer frame 912.

  On the front side of the main body frame 914, a glass door 916, a game ball tray 918, and an operation handle 920 for firing the game ball are provided. The glass door 916 is pivotally supported by the main body frame 914 on one side and closed on the other side close to the main body frame 914 as shown in FIG. 15, and on the other side as shown in FIG. Is freely rotatable between an open position (open state) separated from the main body frame 914.

  Behind the glass door 916, a game board 922 for forming a game area 924 for driving a pachinko ball is arranged, and the game board 922 can be visually recognized through the glass door 916. On the game board 922, a variable display for deriving a display result by variably displaying a plurality of symbols in accordance with winning at a so-called role, starting port, winning port, attacker, out port, game nail, windmill, starting port. A device is provided.

  Also, on the back side of the main body frame 914, a game ball tank for receiving game balls, a payout device for paying out game balls stored in the game ball tank to a tray, various control boards for controlling games and effects, protection A cover, a power supply base case 901 that houses the power supply base, and a main body frame open detection switch 925 for detecting the open state of the main body frame 914 are provided.

  On the front surface of the power supply base case 901, a power switch 939 and a setting switch 938 that are operated when the power is turned ON / OFF are provided. When changing the setting, for example, the main body frame 914 is opened, and the power switch 939 is turned on while the setting switch 938 is being pressed, so that the setting change state in the above-described embodiment is the same. Controlled by the state. In the setting change state, each time the setting switch 938 is pressed, the setting value is updated by one (when the setting switch 938 is further operated, the setting value is returned to setting 1), and a predetermined setting end operation (for example, setting switch 938) The current setting value is set by, for example, pressing 938 for 5 seconds or more, and the setting change state ends. Since the power switch 939 is temporarily turned off and the power switch 939 is turned on while pressing the setting switch 938, the operation is shifted to the setting change state. Therefore, the operations are collectively referred to as a setting change operation.

  As described above, the main body frame 914 which is a gaming machine main body is rotatably attached to the outer frame 912, and the setting change operation can be performed by opening the main body frame 914. . In such a case, it can be said that the main body frame 914 is an opening / closing body. Further, it can be said that the main body frame open detection switch 925 for detecting the open state of the main body frame 914 is an open / closed state detecting means.

  In the pachinko machine shown in FIGS. 15 to 18, for example, a power switch and a setting switch are provided so that the setting change operation can be performed by opening the glass door 916 as shown in FIG. If a glass door open detection switch for detecting the open state of the glass door 916 is provided, it can be said that the glass door 916 is an opening / closing body. Moreover, it can be said that the glass door open detection switch for detecting the open state of the glass door 916 is an open / closed state detection means.

  (7) In the above embodiment, a slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and a game used in a pachinko gaming machine. It may be a so-called parrot that uses a ball (pachinko ball) to set a bet number, or a fully credit type slot machine that sets a bet number using only credits.

  Further, in addition to the medal insertion mechanism such as the flow path switching solenoid 30 and the insertion medal sensor 31, a ball take-in device that takes in game balls, and a take-in ball that detects game balls taken in by the ball take-in device In addition to a medal payout mechanism, such as a hopper motor 34b and a payout sensor 34c, a ball payout device for paying out game balls, a payout ball detection switch for detecting game balls payed out by the ball payout device It is possible to set the number of bets using both medals and game balls and play a game, and the present invention may be applied to a slot machine in which medals and game balls are paid out when a winning occurs.

  (8) In the above-described embodiment, the example has been described in which the setting value for setting the advantage is a value that specifies the probability (winning rate) that it is determined that the winning is permitted. However, the set value may be any value that varies the degree of advantage for the player. For example, an assist time (AT) for executing a navigation effect in which information corresponding to the winning situation is notified or executing the navigation effect is provided. In the slot machine that is controlled to the above, a value that specifies the probability of executing the navigation effect or the probability of controlling to the AT may be used. Further, in a slot machine that is controlled to a replay time (RT) in which the winning probability of a re-gamer is improved by a specific symbol combination, a value that specifies the probability of controlling to the RT may be used. As described above, the winning rates may be the same as long as the player's advantage differs depending on the set value.

  Further, when applied to a pachinko machine, the setting value for setting the advantage may be a value that specifies the probability of winning a big hit. In addition, in pachinko machines with multiple types of hits with different degrees of advantage for players (big hits, medium hits, and small hits), the set value is a value that specifies the probability of winning for each hit type. It may be a value that specifies the total probability of winning for any one. In a pachinko machine that controls to a probability variation state in which the probability of winning a big hit is improved, the set value may be a value that specifies the probability of controlling to the probability variation state.

  (9) In the above-described embodiment, when the power is turned on, it is determined whether or not the setting key switch 37 is in the ON state. When the setting key switch 37 is in the ON state, the front door 1b is based on the door opening detection switch 25. An example has been described in which it is determined whether or not it is in the open state, and if it is in the closed state, it is disabled without shifting to the setting change state. However, the timing for determining whether or not the front door 1b is in the open state is not limited to this. For example, the timing until it is determined whether or not the setting key switch 37 is in the ON state after the power is turned on. It may be. Specifically, it is determined whether or not the front door 1b is in an open state before the processing of Sa11 and Sa31 in FIG. 6 is performed, and when the front door 1b is in an open state, the process proceeds to Sa11 and Sa31. It may be possible to configure such that when the front door 1b is in the closed state, it is not controlled to the setting change state by not shifting to the processing of Sa11 or Sa31. This also makes it possible to prevent the RAM from being cleared and not controlled to the setting change state when a setting change operation is performed due to an illegal act.

  (10) It should be understood that the embodiment disclosed this time is illustrative in all respects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
