  In the present embodiment, a plurality of general winning holes 226 are arranged on the game board 200. When a predetermined ball detection sensor (not shown) detects a ball entering the general winning holes 226 (in the general winning holes 226). In the case of winning), the payout device 152 shown in FIG. 2 is driven, and a predetermined number (for example, 10) of balls are discharged as prize balls to the upper plate 126 shown in FIG. The player can freely take out the balls discharged to the upper plate 126. With these configurations, the player can pay out the winning balls to the player based on winning. The ball that has entered the general winning opening 226 is guided to the back side of the pachinko machine 100 and then discharged to the amusement island side. In this embodiment, a ball to be paid out to a player as a consideration for winning may be referred to as a “prize ball”, and a ball lent to a player may be referred to as a “lending ball”. They are called “balls (game balls)”.

  The normal start port 228 is configured by a device called a gate or a through chucker for determining whether or not a ball has passed a predetermined area of the game area 124. In this embodiment, the left side of the game board 200 is used. One is arranged. Unlike the ball that has entered the general winning opening 226, the ball that has passed through the usual starting port 228 is not discharged to the amusement island side. When a predetermined ball detection sensor detects that a ball has passed through the general map starting port 228, the pachinko machine 100 starts a general map variable game by the general map display device 210.

  In the present embodiment, only one first special figure starting port 230 is disposed at the center of the game board 200. The first special figure starting port 230 is a first starting region where the size of the entrance through which the game ball enters does not change. When a predetermined ball detection sensor detects a ball entering the first special figure starting port 230, the payout device 152 shown in FIG. 2 is driven, and a predetermined number (for example, three) of balls is used as a prize ball. At the same time, the special figure changing game is started by the first special figure display device 212. The ball that has entered the first special figure starting port 230 is guided to the back side of the pachinko machine 100 and then discharged to the amusement island side. The first special figure starting port 230 is one of the starting regions and corresponds to an example of a fixed starting region in which the size of the first special diagram starting port 230 does not change.

  In the present embodiment, only one second special figure start port 232 is disposed below the general view start port 228. That is, the second special figure starting port 232 is provided on the right side of the game board 200.

A combination of the pair of blade members 2321 and the second special figure starting port 232 is provided. It corresponds to variable starting means, and is generally called an electric tulip (electric chew). The pair of blade members 2321 are members that change the difficulty level of winning a prize to the second special figure starting port 232. That is, when the pair of blade members 2321 is closed, it is impossible to enter the second special figure starting port 232, and the mode in which the pair of blade members 2321 is closed is an open / close mode in which winning is difficult. On the other hand, when the universal figure change game is won and the universal figure display device 210 stops and displays the symbol, the pair of blade members 2321 are opened and closed at a predetermined time interval and a predetermined number of times, and the second special figure starting port 232 is opened. The ball can be entered (easy winning state), and the open state in which the pair of blade members 2321 are open is an easy winning state. In other words, the second special figure starting port 232 has either a small size (corresponding to the first size) or a large size (corresponding to the second size) of the entrance (game ball entrance). A variable starting area in which the ease of entering a game ball, which changes from one size to the other, is equivalent to an example of a second starting area. The size of the large size is larger than the size of the entrance of the first special figure starting port 230. In a state where the pair of blade members 2321 are opened, out of the game balls that have entered the game area 124, the second special feature that is the variable start area is more than the game balls that enter the first special figure start opening 230 that is the fixed start area. There are more game balls entering the starting port 232 in the figure. On the other hand, the size of the small size is smaller than the size of the entrance of the first special figure starting port 230 or smaller than the size of the entrance of the first special diagram starting port 230. When a predetermined ball detection sensor detects a ball entering the second special figure starting port 232, the payout device 152 is driven and a predetermined number (for example, four) of balls is discharged to the upper plate 126 as prize balls. At the same time, the special figure variation game by the second special figure display device 214 is started. The ball that has entered the second special figure starting port 232 is guided to the back side of the pachinko machine 100 and then discharged to the amusement island side.

  In the present embodiment, only one variable winning port 234 is disposed below the center of the game board 200. The variable prize opening 234 includes a variable prize opening and a door member 2341 that can be opened and closed by a solenoid. The variable winning opening may be referred to as a big winning opening, and the variable winning opening 234 may be referred to as an attacker. The door member 2341 changes its state from any one of a predetermined closed state and an open state in which a game ball can easily enter the variable winning opening more than the closed state. Both the closed state and the open state are stationary states, and the closed state is a predetermined first stationary state. The closed state at the variable winning opening 234 of this embodiment is that the door member 2341 is on the player side of the game board 200. It is in a stationary state that matches the surface. On the other hand, the open state is a predetermined second stationary state, and the open state in the variable winning opening 234 of the present embodiment is rotated to the player side until the door member 2341 is substantially perpendicular to the game board 200. It is stationary. The variable winning opening 234 is kept closed until a jackpot game to be described later is started, and when the jackpot game is started, the state change is repeated between the open state and the closed state. Note that the closed state may be a state where the game ball is slightly opened to the extent that it is substantially impossible to enter, in addition to a completely closed state. Further, the variable winning opening is not limited to the one shown in FIG. 3 as long as it becomes a winning of the game ball by passing or entering the game ball. When the special figure variable game is won and the first special figure display device 212 or the second special figure display device 214 stops and displays the big hit symbol, the door member 2341 opens and closes at a predetermined time interval and a predetermined number of times. When a predetermined ball detection sensor detects a ball entering the variable winning opening 234, the payout device 152 is driven to discharge a predetermined number (for example, 15 balls) of balls to the upper plate 126 as prize balls. The ball that entered the variable winning opening 234 is guided to the back side of the pachinko machine 100 and then discharged to the amusement island side.

  Further, a plurality of disc-shaped hitting direction changing members 236 called a windmill and a plurality of game nails 238 are arranged in the vicinity of these winning openings and start openings, and at the bottom of the inner rail 204, An out port 240 is provided for guiding a ball that has not won a prize or starting port to the back side of the pachinko machine 100 and then discharging it to the game island side.

<Control unit>
Next, the circuit configuration of the control unit of the pachinko machine 100 will be described in detail with reference to FIG. This figure shows a circuit block diagram of the control unit.

  The control unit of the pachinko machine 100 can be roughly classified into a main control unit 300 that controls the central part of the game and a command signal (hereinafter simply referred to as “command”) transmitted by the main control unit 300. A first sub-control unit 400 that controls the second sub-control unit 500 that controls various devices based on a command transmitted from the first sub-control unit 400, and a command transmitted by the main control unit 300 A payout control unit 600 that mainly performs control related to payout of game balls, a launch control unit 630 that controls the launch of game balls, and a power management unit 660 that controls the power supplied to the pachinko machine 100. Yes. In the present embodiment, the main control unit 300, the first sub control unit 400, and the second sub control unit 500 are composed of different circuit boards, but these three control units (300, 400, 500) are: The first sub-control unit 400 and the second sub-control unit 500 may be composed of one common circuit board different from the circuit board of the main control unit 300. It may be a thing. Therefore, each of the main control unit 300, the first sub control unit 400, and the second sub control unit 500 can be regarded as a predetermined control means, or one of these three control units (300, 400, 500) combined. One can be regarded as a predetermined control means, or one combined with the first sub control unit 400 and the second sub control unit 500 can be regarded as a predetermined control means.

<Main control unit>
First, the main control unit 300 of the pachinko machine 100 will be described.

  The main control unit 300 includes a basic circuit 302 that controls the entire main control unit 300. The basic circuit 302 includes a CPU 304 (corresponding to an example of a game control unit and an abnormality handling unit of the present invention), and ROM 306 for storing control programs and various data, RAM 308 for temporarily storing data (corresponding to an example of the storage means of the present invention), I / O 310 for controlling input / output of various devices, A timer circuit 311 for performing real-time interruption, time measurement, and the like, a counter circuit 312 for measuring time and frequency, and a reset control circuit 314 for controlling system reset and user reset described later (abnormality detection of the present invention) And a crystal oscillator 316a are mounted. Note that other storage devices may be used for the ROM 306 and the RAM 308. In addition, various data representing predetermined information and the like are stored in the ROM 306 for each address, and when referred to as a table in the following description, a condition for determining which address in the ROM 306 is designated is displayed in a table format. May refer to a summary. The same applies to the first sub-control unit 400 and the second sub-control unit 500 described later. The CPU 304 of the basic circuit 302 operates by inputting a clock signal of a predetermined period output from the crystal oscillator 316b as a system clock.

  Further, the basic circuit 302 includes a main body opening sensor 1041, a front frame door sensor 1061, a door sensor with ball storage tray 1082, and a lower tray that detects that the lower tray 128 shown in FIG. Receives signals output from various sensors 320 including a full tank detection sensor and a ball detection sensor provided inside each start opening, winning opening, and variable winning opening, and compares the result of amplification and reference voltage with a random number. A sensor circuit 322 for outputting to the generation circuit 318 and the basic circuit 302, a drive circuit 324 for controlling display of the first special figure display device 212 and the second special figure display device 214, A drive circuit 326 for performing display control, and various status display units 328 (for example, a general map hold lamp 216, a first special figure hold lamp 218, a second special figure hold lamp 220, a high accuracy A drive circuit 330 for performing display control of the lamp 222, etc.), connects the drive circuit 334 for controlling the solenoids 332 for opening and closing the like second Laid view start hole 232 and the variable winning opening 234.

  The random number generation circuit 318 generates a random number used in the basic circuit 302. Random number generation in the random number generation circuit 318 can be broadly divided into two types of methods: counter mode and random number mode. In the counter mode, a numerical value that is counted up (down) at a predetermined time interval is acquired, and the numerical value is derived as a random number. There are two more methods in the random number mode. The first method in the random number mode performs an operation using a predetermined function (for example, a modulus function) using a seed of random numbers, and derives the operation result as a random number. In the second method, a numerical value is read from a random number table in which numerical values in the range of 0 to 65535 are randomly arranged, and the read numerical value is derived as a random number. The random number generation circuit 318 acquires an irregular value using white noise superimposed on signals input from the various sensors 320 to the sensor circuit 322. The random number generation circuit 318 uses the acquired value as an initial value of a counter that counts up (down) in the counter mode, uses it as a seed of random numbers, or determines a read start position of the random number table. Further, the present embodiment is configured such that the range of the generated random numbers can be changed by changing the maximum value of the generated random numbers. This will be described later.

  When the ball detection sensor among the various sensors 320 detects that a ball has won the first special figure starting port 230, the sensor circuit 322 generates a signal indicating that the ball has been detected, as a random number generation circuit 318. Output to. The random number generation circuit 318 that has received this signal latches the value at that timing of the random number generation circuit corresponding to the first special figure starting port 230, and the latched value is incorporated in the random number generation circuit 318. It is stored in a random number storage register corresponding to the starting port 230 in FIG. Similarly, when the random number generation circuit 318 receives a signal indicating that the ball has won the second special figure start port 232, the value at the timing of the random number generation circuit corresponding to the second special figure start port 232 is the same. And the latched value is stored in a random number storage register corresponding to the second special figure starting port 232 incorporated in the random number generation circuit 318. Further, when the random number generation circuit 318 receives a signal indicating that the ball has won the universal start port 228, the random number generation circuit 318 latches the value at the timing of the random number generation circuit corresponding to the general start port 228, The latched value is stored in a random number storage register corresponding to the normal start port 228 built in the random number generation circuit 318.

  In addition, as the ball detection sensor referred to in this specification, specifically, a predetermined prize opening such as a general prize opening 226, a first special figure starting opening 230, a second special figure starting opening 232, a variable winning opening 234 or the like is won.

The game information of the machine 100 (for example, information indicating the control state) is output.

  In addition, the main control unit 300 is provided with a voltage monitoring circuit 338 that monitors the voltage value of the power source supplied from the power management unit 660 to the main control unit 300. The voltage monitoring circuit 338 is a voltage value of the power source. Is less than a predetermined value (9v in this embodiment), a low voltage signal indicating that the voltage has decreased is output to the basic circuit 302. The low voltage signal is an electric system abnormality signal indicating that there is an abnormality in the electric system for operating the CPU 304 of the main control unit 300, and the voltage monitoring circuit 338 corresponds to an example of an electric system abnormality signal output unit.

  In addition, the main control unit 300 is provided with a start signal output circuit (reset signal output circuit) 340 that outputs a start signal (reset signal) when the power is turned on. When an activation signal is input, game control is started (main control section main processing described later is started). The CPU 304 of the main control unit 300 corresponds to an example of game control means.

  The main control unit 300 includes an output interface for transmitting a command to the first sub-control unit 400 and an output interface for transmitting a command to the payout control unit 600. With this configuration, the first control unit 300 Communication with the sub-control unit 400 and the payout control unit 600 is enabled. Information communication between the main control unit 300 and the first sub-control unit 400 and the payout control unit 600 is one-way communication. The main control unit 300 sends commands and the like to the first sub-control unit 400 and the payout control unit 600. The first sub control unit 400 and the payout control unit 600 are configured such that signals such as commands cannot be transmitted to the main control unit 300.

<Sub control unit>
Next, the first sub control unit 400 of the pachinko machine 100 will be described. The first sub-control unit 400 includes a basic circuit 402 that controls the entire first sub-control unit 400 mainly based on commands transmitted from the main control unit 300. The basic circuit 402 includes a CPU 404 and A RAM 408 for temporarily storing data, an I / O 410 for controlling input / output of various devices, and a counter timer 412 for measuring time, the number of times, and the like are mounted. The CPU 404 of the basic circuit 402 operates by inputting a clock signal of a predetermined period output from the crystal oscillator 414 as a system clock. The basic circuit 402 is connected to a ROM 406 for storing control programs and various effects data. The ROM 406 may store the control program and various effect data in separate ROMs.

  The basic circuit 402 includes a sound source IC 416 for controlling the speaker 120 (and amplifier), a drive circuit 420 for controlling various lamps 418, and a drive for performing drive control of the effect movable body 224.

  Furthermore, a second sub-control unit 500 for controlling the decorative symbol display device (liquid crystal display device) 208 and the shielding device 246 is connected to the first sub-control unit 400.

  The sub-control unit that combines the first sub-control unit 400 and the second sub-control unit 500 receives a command signal from the main control unit 300 that is a game control unit, and based on the received command signal, the decorative symbol display device The effect means such as 208 is controlled.

<Discharge control unit, launch control unit, power supply management unit>
Next, the payout control unit 600, the launch control unit 630, and the power management unit 660 of the pachinko machine 100 will be described.

  The payout control unit 600 controls the payout motor 602 of the payout device 152 shown in FIG. 2 mainly based on a signal such as a command transmitted from the main control unit 300, and awards based on a control signal output from the payout sensor 604. While detecting whether or not the payout of the ball or the rental ball has been completed, communication with a card unit 608 provided separately from the pachinko machine 100 is performed via the interface unit 606.

  The launch control unit 630 outputs a control signal output from the payout control unit 600 to permit or stop the launch, or a launch intensity output circuit provided in the ball launch handle 134 to operate the ball launch handle 134 by the player. Based on the control signal instructing the launch intensity according to the amount, the launcher 146 and the launcher motor 632 driving the launcher 148 shown in FIG. The device 634 is controlled.

  The power management unit 660 converts the AC power supplied from the outside to the pachinko machine 100 into a direct current, converts it to a predetermined voltage, and supplies the predetermined voltage to the payout control unit 600 and the second sub-control unit 500. The main control unit 300, the first sub control unit 400, and the launch control unit 630 are supplied with a predetermined voltage from the payout control unit 600. The power management unit 660 also stores a power storage circuit (for example, a power supply circuit) for supplying power to a predetermined component (for example, the RAM 308 of the main control unit 300) for a predetermined period (for example, 10 days) even after the external power supply is cut off. , Capacitor). In the present embodiment, a predetermined voltage is supplied from the power management unit 660 to the payout control unit 600 and the second sub control unit 500, and the main control unit 300, the first sub control unit 400, and the launch control unit are supplied from the payout control unit 600. Although a predetermined voltage is supplied to 630, the predetermined voltage may be supplied to each control unit and each device through another power supply path.

<Type of design>
Next, the first special symbol display device 212, the second special symbol display device 214, the decorative symbol display device 208, and the normal symbol display device 210 of the pachinko machine 100 are stopped and displayed using FIGS. The types of special maps and general maps to be described will be described.

  Fig.5 (a) shows an example of the stop symbol aspect (1st symbol aspect) of a special figure. The special figure 1 variable game is started on the condition that the first start port sensor, which is a ball detection sensor, detects that a ball has entered the first special figure start port 230, and the second special figure start port 232 has a ball. The special figure 2 variable game is started on the condition that the second start port sensor which is a ball detection sensor detects that the ball has entered. When the special figure 1 variable game is started, the first special symbol display device 212 repeats the lighting of all the seven segments and the lighting of the central one segment “variable display of special figure 1” (special figure). (Floating game). When the special figure 2 variable game is started, the second special symbol display device 214 repeats the lighting of all the seven segments and the lighting of the central one segment “variable display of special figure 2” ( (Special map variable game). Then, when the variation time determined before the start of the fluctuation of the special figure 1 elapses, the first special symbol display device 212 stops and displays the stop symbol form of the special figure 1, and the fluctuation time determined before the start of the fluctuation of the special figure 2 When elapses, the second special symbol display device 214 stops and displays the stop symbol form of the special symbol 2. Hereinafter, a series of displays from the start of the “variable display of the special figure 1 or 2” to the stop display of the special symbol form of the special figure 1 or 2 may be referred to as a special figure fluctuation display. This special figure variation display may be continuously performed a plurality of times.

  FIG. 5A shows ten types of special drawings from “special drawing A” to “special drawing J” as stop symbol forms in the symbol variation display. In FIG. 5A, the white portions in the figure indicate the segment locations where the light is turned off, and the black portions indicate the location where the segments are turned on.

  In the present embodiment, six types of jackpot symbols ("Special Figure A" to "Special Figure F") are prepared as the stop pattern modes of special figures. “Special Figure A” is a 15 round (R) special jackpot symbol, and “Special Figure C” is a 2R special jackpot symbol, which is called sudden change. When these symbols (special drawings A and C) are stopped and displayed, the control state thereafter becomes a special figure high probability normal figure high probability state. “Special Figure B” is a 15R jackpot symbol, and “Special Figure D” is a 2R jackpot symbol, which is called a sudden reduction. When the special figure B or the special figure D is stopped and displayed, the control state becomes a special figure low probability normal figure high probability state. “Special figure E” is a 2R jackpot symbol called hidden probability change, and “Special figure F” is a 2R jackpot symbol suddenly called normal. When the special figure E is stopped and displayed, the control state thereafter becomes a special figure high probability normal figure low probability state. When the special figure F is stopped and displayed, the control state thereafter becomes the special figure low probability normal figure low probability state.

  The round here means the number of chances that a predetermined amount of game value (predetermined number of balls) can be obtained. In the present embodiment, the number of operations of the variable prize opening 234 shown in FIG. 3 is represented, and the 15th round is defined as one or more opening / closing operations of the variable prize opening 234 (one operation). This means that this operation continues 15 times. That is, one operation corresponds to an example of a specific change in which the open / close state changes from the first open / close state (here, the closed state) to the second open / close state (here, the open state). During the big hit game, the specific change is performed a plurality of constant times (15 times in the case of 15 rounds). Each round has a predetermined round end condition (for example, the entry of a game ball of a predetermined number of balls (for example, 10 balls), acquisition of a predetermined amount of game value (predetermined number of balls), elapse of a predetermined time from the start of the round, etc. 1 or more) is completed. In the pachinko machine 100 according to the present embodiment, as will be described later, the determination as to whether or not the big hit in the special figure variable game is made by lottery of hardware random numbers, and the decision as to whether or not it is a special big hit is made by lottery of software random numbers. The difference between the big hit and the special big hit or the short time big hit is the difference in the probability of winning the big hit (special big hit or short time big hit) or low (big hit) in the next special figure variation game. Hereinafter, a state having a high probability of winning the jackpot is referred to as a special figure high probability state, and a state having a low probability is referred to as a special figure low probability state. In this embodiment, during the big hit game, the special figure shifts to a low probability state, and if the special figure A, special figure C, and special figure E are won, the special figure will be displayed until the next big hit after the big hit game ends. A high probability state is maintained. On the other hand, when the special figure B, special figure D, and special figure F are won, the special figure low probability state remains even after the big hit game ends. The special figure low probability state corresponds to an example of a first probability control state. In addition, a special figure high probability state after the jackpot game ends may be referred to as a special figure probability change, and a state where the probability of winning a big jackpot after the jackpot game ends (a special figure high probability state) is a player. Is an example of a second stochastic control state. This special figure high probability state may be referred to as a probability variation state. In the present specification, the term “control state” will be used to describe the state inside the gaming machine (pachinko machine 100). The term “control state” includes the concept of a so-called gaming state. The transition of the probability control state is performed by the main control unit 300, and the main control unit 300 corresponds to an example of a probability control state transition unit.

  In addition, if the special drawings A to D are won, all of them shift to a state with electric support (electric support) (hereinafter referred to as an electric support state) after the big hit game ends. The electric support state is a predetermined state in which the player's advantage is higher than the non-electric support state by shortening the time from the end of the big hit in the special figure variable game to the start of the next big hit. Say. This power support state is one of the control states prepared in the pachinko machine 100, and may be referred to as a time-short state. That is, the electric support state (time-short state) is started on condition that the big hit game ends. Strictly speaking, the “electric support state” is a state related to a general plan, and the “short-time state” is a state related to a special figure or a state related to a general figure and a special figure. The RAM 308 of the main control unit 300 is also provided with a time reduction flag. When the time reduction flag is set to ON, it is in the electric support state and is usually in a high probability state. In the normal figure high probability state, compared to the normal figure low probability state, it becomes easier to win the common figure variable game (general figure certain change). For example, the winning probability of the usual figure floating game is 1/101 in the usual figure low probability state (non-electric support state), but increases to 99/101 in the usual figure high probability state (electric support state). In addition, in the electric support state, the fluctuation time of the general figure change game is shorter than that in the non-electric support state (the general figure change short). For example, in the non-electric support state, the fluctuation time of the usual game of 10 seconds is reduced to 1.2 seconds in the electric support state. Further, in the electric support state, compared to the non-electric support state, the opening time in one opening of the pair of blade members 2321 of the second special figure starting port 232 tends to be long (electric chew releasing period extension). For example, in the non-electric support state, the electric chew release period of 0.3 seconds is extended to 1.7 seconds in the electric support state. Furthermore, the pair of blade members 2321 are more likely to open in the electric support state than in the non-electric support state (increase the number of times the electric chew is released). For example, a pair of blade members 2321 that can be opened only once in the non-electric support state per opening to the normal start port 228 is opened three times in the electric support state (for example, 3 to open for 1.7 seconds) Repeatedly, the closing time between opening is 1.6 seconds). The probability of entering the second special figure starting port 232 increases due to the extension of the electric chew release period and the increase in the number of electric chew release times. Note that the hourly flag is set to off during the big hit game. Therefore, the non-electric support state is maintained during the big hit game. This is because, if the power is supported during the big hit game, a predetermined number of game balls are placed in the second special figure starting port 232 until the predetermined number of game balls are entered during the big hit game. In order to solve this, there is a problem that the number of game balls that can be entered during a big hit and the number of game balls that can be acquired increases, resulting in an increase in gambling. In the present embodiment, in the electric support state (short-time state), all of the normal figure change, the universal figure change, the electric chew release period extension, and the electric chew release frequency increase are performed. If any one is performed, a player's advantage will be in a high state and it may be in an electric support state (time-short state). Alternatively, if either one of the extension of the electric chew release period or the increase in the number of electric chew release is performed, the electric support state (short-time state) may be set. . In the non-electric support state, the game ball is less likely to enter the second special figure starting port 232 than in the electric support state. As described above, in the second special figure starting port 232, the size of the entrance into which the game ball enters changes from one of the small size and the large size to the other size. The entrance of the second special figure starting port 232 is larger in the electric support state over a longer period than in the non-electric support state. In the present embodiment, when special figure A and special figure C are stopped and displayed, the electric support state (ordinary figure high probability state) is maintained until the next big hit game is started after the subsequent big hit game is completed. When the special figure B and the special figure D are stopped and displayed, the electric support state is maintained while the special figure variable game is performed 100 times after the subsequent big hit game is finished, and the non-electric support state is displayed at the 101st time. Transition to (ordinary low probability state). On the other hand, when a big hit without special support (special figure E, special figure F) is won, it does not shift to the electric support state after the big hit game ends. In the non-electric support state, the entrance of the second special figure starting port 232 is kept small. On the other hand, as described above, in the electric support state, the entrance of the second special figure starting port 232 is large, and the entry rate of game balls is increased. That is, in the non-electric support state, the game ball enters the second special figure start port 232 that is the variable start area at the first approach rate, whereas in the electric support state, the game ball starts the second special figure start. It enters the mouth 232 at a second approach rate that is higher than the first approach rate. Therefore, the non-electric support state corresponds to an example of the first approach rate control state, and the electric support state corresponds to an example of the second approach rate control state.

  Furthermore, in this embodiment, two types of stop symbols are prepared as small hit symbols in addition to the big hit symbol. The special figure G shown in FIG. 5 (a) is the first small hit symbol, and the special figure H is the second small hit symbol. In the small hit game, the door member 2341 of the variable prize opening 234 is operated a predetermined number of times (for example, 15 times), and the door member 2341 maintains the open state for a maximum of 1.5 seconds per operation. In opening the door member 2341 at the small hit, for example, when a game ball enters a predetermined number of balls (for example, 10 balls) in the first opening, or a predetermined amount of game value (a predetermined number of balls) is acquired. As a result, the second and subsequent releases are not performed. During the small hit game, it shifts to the special figure low probability normal figure low probability state. The small hit is a role in which the control state does not change before and after the small hit game, and after the small hit game is finished, the control state returns to the control state before the start of the small hit game.

  In the big hit game and the small hit game, the door member 2341 of the variable winning opening 234 is opened or closed one or more times, and the player's advantage is relatively high.

  In this embodiment, two types of lost symbols are also prepared. The special figure I shown in FIG. 5 (a) is the first lost symbol, and the special figure J is the second lost symbol. When the lose symbol is stopped and displayed, the door member 2341 of the variable winning opening 234 is not opened and closed, and the player's advantage is relatively low. In addition, a losing symbol other than “special symbol I” and “special symbol J” (for example, a third losing symbol or the like) may be prepared. In this embodiment, the losing symbol includes a plurality of types of symbols. It is a waste.

  As described above, in the pachinko machine 100 according to the present embodiment, the hit control state (the big hit control state and the small hit control state) of the second advantage that the player's advantage is high, and the second advantage. A loss control state having a first advantage with a low advantage is prepared, and the pachinko machine 100 is in one of a hit control state (second control state) and a loss control state (first control state). Take control state. The transition of the control state is also performed by the CPU 304 of the main control unit 300, and the CPU 304 of the main control unit 300 corresponds to an example of a control state transition unit. In the small hit control state, although the door member 2341 of the variable prize opening 234 opens and closes, it is almost impossible to expect a ball to enter the variable prize opening 234. It can also be regarded as a control state (first control state).

  In the pachinko machine 100 according to the present embodiment, symbols other than “special symbol A” are prepared as the jackpot symbol 1, and the same applies to other symbols such as the jackpot symbol 2.

  The first special figure display device 212 and the second special figure display device 214 are notifying means for informing the determination result (lottery result), and the pattern mode ( This corresponds to an example of the symbol display means for displaying the symbol variation until the special symbols A to J) are stopped and displayed.

  FIG. 5B shows an example of a decorative design. There are 10 types of decoration patterns of the present embodiment: “Decoration 1” to “Decoration 10”. The first start port sensor detects that a ball has won the first special figure start port 230 or the second special view start port 232, that is, the ball has entered the first special view start port 230; or On the condition that the second start port sensor detects that a ball has entered the second special symbol start port 232, the left symbol display area 208a, the middle symbol display area 208b, and the right symbol display of the decorative symbol display device 208 are displayed. Displayed in the order of “decoration 1” → “decoration 2” → “decoration 3” →... “Decoration 9” → “decoration 10” → “decoration 1” →... “Decoration display of decorative pattern” is performed. That is, the decorative symbol display device 208 variably displays the decorative symbols separately from the first special symbol display device 212 and the second special symbol display device 214. And the stop symbol aspect (2nd symbol aspect) which is a combination of a decoration symbol is stopped and displayed. When notifying “Special Figure A”, which is a 15R special jackpot, or “Special Figure C”, which is a 2R special jackpot, three “odd” decorative symbols are arranged in the symbol display areas 208a to 208c. The combination 2 ”(for example,“ decoration 3—decoration 3—decoration 3 ”,“ decoration 5—decoration 5—decoration 5 ”, etc.) is stopped and displayed. When notifying “Special Figure B” which is a 15R jackpot, “decoration pattern combination 1” (for example, “decoration 2-decoration 2—decoration 2” in which three same-numbered ornamental patterns are arranged in the symbol display areas 208a to 208c. “Decoration 2”, “decoration 4—decoration 4—decoration 4”, etc.) are stopped and displayed. In the case of notifying “special drawing E” that is a hidden probability change, “special drawing F” that is suddenly normal, “special drawing G” and “special drawing H” that are small hits, the symbol display area 208a. ˜208c, “decoration pattern combination 3” such as “decoration 1—decoration 2—decoration 3” is stopped and displayed, and “special drawing C” that is suddenly probable or “special drawing D” that is suddenly short is reported. In this case, “decorative symbol combination 4” such as “decoration 1-decoration 3—decoration 5” is stopped and displayed in the symbol display areas 208a to 208c. Further, when notifying “special drawing I” and “special drawing J” that are lost, decorative symbols other than “decorative symbol combination 1” to “decorative symbol combination 4” are displayed in the symbol display areas 208a to 208c. The combination (for example, loose eye) is stopped and displayed. Hereinafter, in the decorative symbol display device 208, a series of displays from the start of this “decorative symbol variable display” until the stop symbol mode of the decorative symbol (for example, “decorative symbol combination 2”) is stopped are displayed. Sometimes referred to as symbol variation display.

  In addition, the stop symbol mode (see FIG. 5A) of the special symbol 1 and the special symbol 2 and the stop of one decorative symbol displayed in each of the left and right symbol display areas 208a to 208c of the decorative symbol display device 208. The decorative pattern (see FIG. 10B) is larger in the design (see FIG. 10B).

  FIG.5 (c) shows an example of the usual stop symbol mode (2nd symbol mode). In the present embodiment, there are two types of stoppage display modes for ordinary maps: “general diagram A” which is a winning symbol and “general diagram B” which is a lost symbol. Based on the fact that the gate sensor, which is a sphere detection sensor, detects that the sphere has passed through the general start port 228, the general display display device 210 illuminates all seven segments and the central one segment. Repeat the lighting and perform “variable display of ordinary figure” (ordinary figure fluctuation game). Then, after the fluctuation time has elapsed, one of the symbols “general symbol A” which is a winning symbol and “general symbol B” which is a lost symbol is stopped and displayed. Also in FIG. 5C, the white portions in the drawing indicate the locations of the segments that are turned off, and the black portions indicate the locations of the segments that are turned on.

  Hereinafter, a series of displays from the start of the “variable display of the normal diagram” to the stop display of the stop symbol pattern of the normal diagram may be referred to as a normal diagram of variable display. The universal symbol display device 210 corresponds to an example of auxiliary symbol notification means.

<Example of basic circuit configuration of main controller>
Next, a configuration example of the basic circuit 302 of the main control unit 300 will be described with reference to FIG. This figure is a diagram showing a configuration example of the basic circuit 302 shown in FIG.

  6 includes a CPU 304, a ROM (built-in ROM) 306, a RAM (built-in RAM) 308, an external bus control circuit 3101, a parallel input port 3102, an address decoding circuit 3103, a timer circuit 311, a counter circuit 312, In addition to the reset control circuit 314, an interrupt control circuit 3100, a clock circuit 3200, and a random number generation circuit 318 are provided, all of which are connected to each other via an internal bus 3300.

  Note that the external bus control circuit 3101, parallel input port 3102, and address decode circuit 3103 correspond to the I / O 310 in FIG. 4.

  Hereinafter, details of each of the above-described units will be described.

  First, the CPU 304, the ROM 306, and the RAM 308 are as described with reference to FIG.

  The external bus control circuit 3101 includes an IO request terminal (XIORQ terminal), a memory request terminal (XMREQ terminal), a read signal terminal (XRD terminal), a write signal terminal (XWR terminal), a 16-bit width address output terminal (A0 terminal to A15 terminal) and data input / output terminals (D0 terminal to D7 terminal) which are input / output terminals having an 8-bit width. In this embodiment, the data input / output terminals (D0 terminal to D7 terminal) are used for data output to the drive circuits 324, 326, 330, and 334 shown in FIG. 4 and data input from the peripheral control circuits. It has been. The data input / output destinations of the data input / output terminals (D0 terminal to D7 terminal) are the address signal output from the address output terminals (A0 terminal to A15 terminal) and the chip select signal output from the address decode circuit 3103. Use to switch.

  The parallel input port 3102 has four input terminals (P0 terminal to P3 terminal). These input terminals (P0 terminal to P3 terminal) are connected to the sensor circuit 322 shown in FIG. 4 and are used to input signals from the sensor circuit 322. In this embodiment, a signal from a sphere detection sensor that detects a ball entering the first special figure start port 230 is input to the P0 terminal, and a ball detection sensor that detects a ball entering the second special figure start port 232 is used. Is input to the P1 terminal, and a signal from a ball detection sensor that detects a ball entering the normal start port 228 is input to the P2 terminal. The signal from the sensor circuit 322 is output to the random number generation circuit 318 as a latch signal for causing the CPU 304 to acquire a random number generated by the random number generation circuit 318. This operation will be described later.

  The address decoding circuit 3103 has 14 output terminals (XCS0 terminal to XCS13 terminal). The output terminals (XCS0 terminal to XCS13 terminal) are connected to a peripheral control circuit outside the basic circuit 302, and data output from the data input / output terminals (D0 terminal to D7 terminal) of the external bus control circuit 3101. Is used to output a chip select signal or the like for switching the transmission destination.

  The timer circuit 311 is used for time measurement. The timer circuit 311 outputs a timeout signal to the counter circuit 312 when the set measurement time has passed. On the other hand, the counter circuit 312 is used for measuring the number of rises (or falls) of various signals. In addition to the system clock of the basic circuit 302, the signal measured by this counter circuit also measures a timeout signal from the timer circuit, a memory read / write signal, a memory request signal, an external input / output signal, an interrupt response signal, and the like. can do.

  The reset control circuit 314 has two terminals, a system reset input terminal (XSRST terminal) and a reset output terminal (XRSTO terminal). This system reset input terminal (XSRST terminal) is connected to the voltage monitoring circuit 338. When a system reset signal (for example, L level signal) is input from the system reset input terminal (XSRST terminal), the reset control circuit 314 outputs the system reset signal to the internal circuit of the basic circuit 302. At the same time, a reset signal (for example, a rising signal from L level to H level) is output from the reset output terminal (XRSTO terminal) to the peripheral control circuit outside the basic circuit 302. In this case, the basic circuit 302 executes a process called system reset and initializes each circuit. An example in which this system reset is executed is when the power is turned on. This system reset will be described later.

  Further, the reset control circuit 314 includes a watch dog timer (WDT) 3141 (corresponding to an example of the return instruction means of the present invention), and a designated area outside travel prohibition circuit 3142. When the WDT 3141 times out or when the CPU 304 refers to an address outside the predetermined range (running outside the designated area), the reset control circuit 314 sends a system reset signal to the circuit inside the basic circuit 302 and One of the user reset signals is output. Whether to output the system reset signal or the user reset signal depends on the setting of the program management area (details will be described later) in the ROM 306. A reset signal is output from a reset output terminal (XRSTO terminal) to the peripheral control circuit outside the basic circuit 302.

  The basic circuit 302 can execute either the above-described system reset or processing called user reset depending on the setting. In the user reset, each circuit is initialized as necessary. This user reset will be described later.

  The traveling outside the designated area means that the program is operating unexpectedly. In this case, the CPU 304 operates with a code that should not be handled as a program. Such a situation may be caused by some sort of fraud other than a so-called runaway state due to a program mistake. In this case, normal operation can be restored by any one of the system reset and user reset processes described above. In addition, when the WDT 3141 times out, there are a runaway state due to a program error, a case where the CPU 304 cannot perform the originally designed operation due to a voltage drop, and the like. Also in this case, the normal operation can be restored by any one of the above-described system and user reset processes.

  The interrupt control circuit 3100 generates an interrupt in order to appropriately execute a process according to a change in external input or internal state. This interrupt process includes, for example, a process executed when an external input (signal from a sensor) is received. In this embodiment, even when the random number generation circuit 318 receives a latch signal for acquiring a random number, it can execute interrupt processing (generate an interrupt). The interrupt control circuit 3100 includes an internal information register 3101. The internal information register 3101 includes an abnormality in the cycle of the external clock (count clock) that determines the random number update cycle by the random number generation circuit 318, and update of the random number. In addition, information on the reset factor of the user reset that occurred immediately before is stored. The internal information register 3101 corresponds to an example of an abnormality detection information holding unit.

  The clock circuit 3200 is an external clock (24 MHz in this example) input from the crystal oscillator 316b shown in FIG. 4 (hereinafter sometimes referred to as a system crystal oscillator 316b) via an external clock input terminal (EX terminal). Is divided by a predetermined frequency division ratio (1/2 in this example), and the divided system clock (12 MHz clock in this example) is supplied to each circuit in the basic circuit 302. . The system clock is output to a peripheral control circuit outside the basic circuit 302 via a system clock output terminal (CLKO terminal).

  The random number generation circuit 318 uses the clock signal (count clock) for updating the random number and holds the updated random number in the random number register when the random number latch signal is received. In the present embodiment, the external clock signal input from the crystal oscillator 316a via the external clock input terminal (RCK terminal) is divided by a predetermined frequency division ratio (1/2 in this example) and is used as this count clock. Although it is used, a clock signal in the basic circuit 302 can also be used. In this case, the crystal oscillator 316a is unnecessary. The value held in the random number register can be read and used as a random number. Note that when a random number is read from the random number register, an allowable state in which the random number register is allowed to latch the next random number can be set. Details of the random number generation circuit 318 will be described later.

<Memory map and I / O map>
Next, an example of a memory map and an I / O map of the basic circuit 302 illustrated in FIG. 6 will be described with reference to FIG. The figure shows an example of a memory map and an I / O map of the basic circuit 302.

  FIG. 7A shows an example of a memory map in the basic circuit 302 shown in FIG. This memory map shows an address space from 0000H to FFFFH. Among these, the ROM 306 is allocated to the space from 0000H to 2FFFH, the RAM 308 is allocated to the space from F000H to F3FFH, and the internal circuit included in each circuit in the basic circuit 302 is allocated to the space from FE00H to FEBFFH. Registers are allocated. By causing the CPU 304 to execute an instruction to access these addresses, it is possible to execute access to the corresponding hardware. The space from 0000H to 2FBFH (12224 bytes) is used to store program code and program data used by this program. The space from 2FC0H to 2FFFH (64 bytes) is used as a program management area. The space used. In the program management area, various settings used when operating the basic circuit 302 (random number generation circuit operation settings, WDT 3141 operation settings, etc.) and various identification information (product code, manufacturer code, ID number, etc.) are stored. Stored.

  FIG. 7B shows an example of the I / O map in the basic circuit 302 shown in FIG. This I / O map shows an input / output space from 00H to FFH. FIG. 7B shows an example in which built-in registers are allocated in the space from 00H to BFH. In this case, by making the CPU 304 execute input / output instructions for these addresses, input / output can be performed for the built-in registers. In the basic circuit 302 shown in FIG. 6, it is selected whether the internal register is assigned on the memory map as shown in FIG. 7A or on the I / O map as shown in FIG. 7B. Can be done. In other words, any method can be selected depending on the design policy. In the present embodiment, the method of FIG. 7A is adopted.

<Reset processing>
Next, the flow of system reset will be described with reference to FIG. This figure shows the flow of system reset.

  As described above, when the system reset signal is input from the XSRST terminal of the reset control circuit 314, a process called system reset is executed.

  First, the system reset signal is an L level signal for a predetermined time (for example, four cycles of the system clock). When this signal is input to the XSRST terminal, a system reset is started. FIG. 8 shows that the input signal of the XSRST terminal rises to the H level immediately after passing the L level for a predetermined time. Here, the description will be continued assuming that the system reset signal is immediately before the H level.

  When the system reset signal is input to the reset control circuit 314, the system reset signal is transmitted from the reset control circuit 314 to the circuit in the basic circuit 302. As a result, all internal circuits including the CPU 304 are initialized, shift to the security mode, and then shift to the user mode. The operation mode shown in FIG. 8 shows that the system shifts to the security mode after the system reset signal and then shifts to the user mode. At this time, an L level signal is output from the XRSTO terminal of the reset control circuit 314.

  Here, the user mode is a mode in which the CPU 304 executes processing according to a program stored in the ROM 306. More specifically, an instruction is read from address 0000H of the memory map and processing is started. On the other hand, the security mode is a mode before shifting to the user mode, and is a mode in which a security check process for operating the CPU 304 normally in accordance with a program stored in the ROM 306 is performed in the user mode.

  In the security check process, the ROM 306 check, the built-in register check, and the like are executed. If there is an abnormality here, the operation of the CPU 304 is stopped.

  Following this security check process, a fixed extension process and a random extension process are executed. The fixed extension process is a process of extending the security mode by a set fixed time. The random extension process is a process of extending the security mode by a random time within a set time range. These fixed time and random time can be set in the program management area described above.

  When the fixed extension process is completed, an H level signal is output from the XRTSO terminal. FIG. 8 shows that the signal at the XRSTO terminal rises from the L level to the H level at the end of the fixed extension process. With this signal, the state of the peripheral circuit of the microprocessor 3000 is initialized.

  When the random extension process is completed following the fixed extension process, the security mode is shifted to the user mode, and a game control program (specifically, a main control unit main process described later) is executed.

  Here, the effect of the above configuration will be described.

  The game machine is controlled using random numbers generated by the random number generation circuit 318. However, since this random number is generated by a random number table or a predetermined calculation, even if it is seemingly random, it has regularity. In order to eliminate such regularity, it is conceivable to use an element having no regularity such as the number of winnings, but such an element cannot be used when a game is not progressing immediately after the power is turned on. Further, when an element having no regularity such as noise is used, it cannot be used if the noise is at a level that cannot be detected. For this reason, the state after the power is turned on or immediately after the system reset is a period in which regularity becomes more prominent, and is likely to be an unauthorized target.

  When the system reset is executed in the basic circuit 302, it is unclear what signals are being transmitted / received in the internal circuit. However, transmission / reception of signals to / from a circuit connected outside the basic circuit 302 can be measured. Further, a reset signal is transmitted to a circuit outside the basic circuit 302 at the time of system reset. If the game control program is started simultaneously with the output of the reset signal to the external circuit, it is analyzed what signals are being exchanged immediately after the system reset, and fraud is performed based on the regularity. There is a risk of being. Further, even if it is not simultaneously with the output of the reset signal, the same fraud may be performed if the period until the game control program is started is a fixed period.

  In the system reset described above, a reset signal is output from the XRSTO terminal to an external circuit, but thereafter, the period until the start of the user mode is randomly changed by random extension processing. With this configuration, the above fraud can be prevented.

  Note that the system reset can also be executed when the WDT 3141 times out due to the setting or when the vehicle travels outside the designated area. In this embodiment, it is set so that a user reset is executed instead of a system reset.

  Next, a processing flow when reset is executed will be described with reference to FIG. This figure is a flowchart showing the flow of reset. This flowchart is a process executed in each circuit of the basic circuit 302 when a system reset signal is input to the reset control circuit 314, when the WDT 3141 times out, or when traveling outside the designated area is detected. .

  In the first step SH01, it is determined whether or not the reset operation to be executed is a system reset operation. There are two reset operations executed by the basic circuit 302: a system reset operation (see FIG. 8) and a user reset operation. Here, when the system reset operation is executed, the process proceeds to step SH03. When executing a reset operation that is not a system reset operation, that is, a user reset operation, the process proceeds to step SH11.

  In step SH03, a first internal circuit initialization process is executed. This first internal circuit initialization process is performed by the CPU 304 core and built-in registers (timer circuit 311, counter circuit 312, parallel input port 3102, RAM 308 access protect register, interrupt control circuit 3100, and random number generation circuit 318). Initialize the value. When the first internal circuit initialization process is completed, the process proceeds to step SH05.

  In step SH05, a security check process is executed. In this security check process, it is recalculated whether the authentication code (stored in the program management area of the ROM 306) calculated based on the user program is correct. If the authentication code is correct, the process proceeds to step SH07. If not, the operation of the CPU 304 is stopped.

  In step SH07, a fixed extension process is executed. In this fixed extension process, the security mode is extended for a preset fixed time (for example, set using 0 to 2 bits of the security time setting in the program management area of the ROM 306). For example, when n is the time set in the program management area and the system clock is SCLK, the time is extended by 3n × 2 ^ 24 / SCLK seconds. A reset signal is output from the XRSTO terminal when this extended time has elapsed. Thereafter, the process proceeds to step SH09.

  In step SH09, a random extension process is executed. In this random extension process, the security mode is extended by a random time selected in advance (for example, setting using 3 to 4 bits of security time setting in the management area). For example, when the short mode is set, the time is extended from 0 to Sμ seconds, when the middle mode is set, 0 to Mμ seconds, and when the long mode is set, the time is extended from 0 to Lμ seconds ( S <M <L). When this process ends, the process shifts to the user mode, and the CPU 304 starts the process from address 0000H in the memory map. In the present embodiment, the main process of the main control unit 300 is started.

  On the other hand, in step SH11 which proceeds when executing the user reset operation in step SH01, the second internal circuit initialization process is executed. In the second internal circuit initialization process, the values of the core of the CPU 304 and the built-in registers (timer circuit 311, counter circuit 312, parallel input port 3102, RAM 308 access protect register, interrupt control circuit 3100) are initialized. However, the value of the register that controls the random number generation circuit 318 is maintained in the state before the reset. When the second internal circuit initialization process is completed, the process shifts to the user mode, and the CPU 304 starts the process from address 0000H in the memory map. In the present embodiment, the main process of the main control unit 300 is started.

<Random number generation circuit>
Next, details of the random number generation circuit 318 of the basic circuit 302 shown in FIG. 6 will be described with reference to FIG. This figure is an internal block diagram of the random number generation circuit 318 shown in FIG.

  The random number generation circuit 318 includes four random number generation channels CH1 to CH4 that generate different random numbers. Since the internal configuration of each channel circuit is the same, FIG. 10 shows one random number generation channel CH1, and the remaining random number generation channels CH2 to CH4 are simplified in illustration. In the following description, the random number generation circuit 318 will be described focusing on the random number generation channel CH1.

  The random number generation circuit 318 includes an initial setting register 3181, a frequency monitoring circuit 3182, a random number updating circuit 3183, a random number monitoring circuit 3184, a noise filter 3185, a soft latch register 3186, a latch selection register 3187, and a random number register 3188. And a random number latch flag register 3189 and a random number interrupt control register 3180. The frequency monitoring circuit 3182 and the random number monitoring circuit 3184 correspond to an example of update abnormality detection means of the present invention.

  The initial setting register 3181 stores clock selection information for determining which of the external clock signal from the RCK terminal and the system clock (internal clock signal) to use in the random number update circuit 3183 in the program management area. Set based on information. The external clock signal and the system clock (internal clock signal) from the RCK terminal are input to a multiplexer provided in front of the random number update circuit 3183. The initial setting register 3181 inputs the update clock selection signal to the multiplexer according to the clock selection information, so that the clock signal selected by the update clock selection signal is input to the random number update circuit 3183. When an external clock signal is selected, a clock signal divided by a predetermined frequency division ratio (in this example, 1/2) is input to the random number update circuit 3183. Note that the frequency-divided clock signal cannot be used when the frequency is not lower than that of the internal clock. In the present embodiment, the description will be continued assuming that the external clock signal is selected.

  The frequency monitoring circuit 3182 monitors the period of the internal clock signal and the external clock signal, and outputs information indicating that the clock signal is abnormal to the internal information register 3101 when the period is not constant.

  The random number update circuit 3183 receives the clock signal selected by the initial setting register 3181 and updates the random number according to the cycle of the clock signal. The updated random number value is output to the random number monitoring circuit 3184 and the random number register 3188, respectively. Details of the random number update circuit 3183 will be described later with reference to FIGS.

  Based on the input from the random number update circuit 3183, the random number monitoring circuit 3184 monitors whether or not the random number has been updated normally. If there is an abnormality in updating the random number, information indicating that there is an abnormality in updating the random number is output to the internal information register 3101.

  In the above description, the frequency monitoring circuit 3182 and the random number monitoring circuit 3184 are provided inside the random number generation circuit 318, but may be provided outside the random number generation circuit 318. In the above description, the frequency monitoring circuit 3182 and the random number monitoring circuit 3184 are provided separately from the random number update circuit 3183. However, these circuits may be provided inside the random number update circuit 3183.

  Input from the P0 terminal to P3 terminal is input to the noise filter 3185 as a latch signal via the parallel input port 3102. In FIG. 10, the P3 terminal and the circuit connected to the P3 terminal are not shown. As described above, a signal from a ball detection sensor that detects a ball entering the first special figure starting port 230 is input to the P0 terminal, and a ball entering the second special figure starting port 232 is input to the P1 terminal. A signal from a sphere detection sensor to be detected is input, and a signal from a sphere detection sensor that detects a ball entering the normal start port 228 is input to the P2 terminal. Further, the clock signal selected by the initial setting register 3181 is input to the noise filter 3185. Using this clock signal, the noise generated at the inputs from the P0 to P3 terminals is removed, and then the latch signal is detected. When this latch signal is detected, a hard latch signal is output to a multiplexer provided in front of the random number register 3188. Details of the noise removal will be described later with reference to FIG.

  Information indicating that a random number is latched from the random number register 3188 is appropriately set in the soft latch register 3186 according to an instruction from the CPU 304. This information is output as a soft latch signal to a multiplexer provided in front of the random number register 3188.

  The latch selection register 3187 has information indicating which of the hard latch signal and the soft latch signal is output from the multiplexer provided in front of the random number register 3188, that is, which latch signal is input to the random number register 3188. These are set as appropriate according to instructions from the CPU 304. By setting this information, a random number can be obtained by appropriately using a hard latch signal and a soft latch signal.

  Three signals are input to the random number register 3188. The first signal is a signal representing a random number output from the random number update circuit 3183. The second signal is a random number latch signal (a signal set by the latch selection register 3187 out of the hard latch signal and the soft latch signal) output from the multiplexer provided in front. The third signal is a read signal indicating random number reading.

  A signal indicating the random number updated by the random number update circuit 3183 is always input to the random number register 3188. Here, when a random number latch signal is input, a random number at this input timing is latched (held) in the random number register 3188. At this time, a set signal indicating that the random number is latched is output from the random number register 3188 to the random number latch flag register 3189. At this time, the CPU 304 can acquire the latched random number. Note that when a random number is acquired by the CPU 304, a read signal is input to the random number register 3188. When a new random number latch signal is input by this signal, an allowable state is entered in which the random number is allowed to be latched. In other words, once the random number is latched, it becomes an unacceptable state in which the random number cannot be newly latched until the read signal is inputted. Note that since the latched random number is held even when a read signal is input, the CPU 304 can acquire the latched random number any number of times at the same latched timing. With this configuration, the influence of chattering in the sensor circuit that outputs the random number latch signal can be suppressed. A clear signal indicating that the read signal has been input is output to the random number latch flag register 3189. Also, as shown in FIG. 10, since there are a plurality of random number registers 3188, random numbers generated from the same random number update circuit can be acquired at various timings.

  The random number latch flag register 3189 stores information indicating whether or not a random number is latched in the random number register 3188.

  In the random number interrupt control register 3180, information indicating whether or not an interrupt is to be generated in the interrupt control circuit when a random number is held in the random number register 3188 is set. This information can be set for each random number register 3188. For example, when the random number of the random number generation channel CH1 is latched by entering the first special figure starting port 230, an interrupt is generated, and by entering the second special figure starting port 232, the random number generating channel CH2 is set. If a random number is latched, it can be set such that no interrupt is generated.

  In the present embodiment, using the random number generation circuit 318 described above, random numbers are acquired at the timing when the ball enters each of the general map start port 282, the first special figure start port 230, and the second special diagram start port 232. Note that the program can be executed so that the CPU 304 can acquire a random number at an arbitrary timing. Further, independent random numbers can be acquired using different random number generation channels, and the maximum value of the random number generation range can be set for each channel.

  In the present embodiment, the example in which the random number generation range can be changed for each individual channel and a predetermined maximum value (for example, 65535) is applied when the range is not set has been described. For example, when changing the random number generation range, the configuration may be required to set the random number generation range for all channels.

  In addition, the random number acquired at the timing of entering the general figure starting port 282 is used as a general figure winning random number described later. In addition, the random number acquired at the timing of entering the first special figure starting port 230 is counted up (down) by processing (for example, a circuit different from the random number generation circuit (for example, the basic circuit 302 or the counter circuit 312)). The value is added (subtracted) to the random number, etc.) and used as a special figure 1 winning random number described later. Furthermore, the random number acquired at the timing of entering the second special figure starting port 232 is processed and used as a special figure 2 winning random number described later.

  The random number processing is not limited to the random number acquired at the timing of entering the first special figure starting port 230 and the second special figure starting port 232, but other triggers (for example, entering the normal figure starting port 282). You may perform with respect to the random number acquired by the timing of balling etc.). Furthermore, when the maximum value of the random number generation range described above is set, processing corresponding to the set maximum value (for example, a process of adding a value not exceeding the maximum value to the random number) may be performed.

  In addition, although it is not always necessary to perform random number processing, it is effective to prevent random numbers from being processed. For example, when the CPU 304 monitors whether or not the processed random number has been updated, it cannot be accurately determined whether or not the random number update in the random number generation circuit 318 is normally performed. Thus, when processing random numbers, monitoring of update of random numbers by the random number monitoring circuit 3184 described above works more effectively.

  Next, the operation of the noise filter 3185 will be described with reference to FIG. This figure is a diagram showing an example of processing by the noise filter 3185 shown in FIG.

  As described above, the noise filter 3185 receives inputs from the P0 to P3 terminals as latch signals via the parallel input port 3102 and receives the clock signal selected by the initial setting register 3181. For example, as shown in FIG. 11, the noise filter 3185 receives the input signal from the P0 terminal to the P3 terminal until the down edge of the clock signal (the falling signal from the H level to the L level) is continuously input four times. If H is at the H level, a hardware latch signal is output. If a hardware latch signal is simply output based on only the rising and falling edges of the signal, the hardware latch signal is output even when noise occurs. For this reason, the hardware latch signal is not output due to noise by detecting the sensor signal for a certain period using the clock signal as described above.

  In the above description, the example in which the hard latch signal is output by the input from the P0 terminal to the P3 terminal has been described. However, for example, there is a method of acquiring the random number after the CPU 304 once receives the input from the P0 terminal to the P3 terminal. . In this case, the random number is latched not by the hard latch signal but by the soft latch signal output from the soft latch register 3186. In this case, the CPU 304 executes processing similar to the processing by the noise filter. That is, it is determined whether or not the input from the P0 terminal to the P3 terminal has continued for a predetermined period, and when this is satisfied, it is determined that the input from the P0 terminal to the P3 terminal has been correctly performed. Thereafter, the soft latch register 3186 is set so as to output a soft latch signal.

  Next, details of the random number update circuit 3183 shown in FIG. 10 will be described with reference to FIG. This figure shows the details of the random number update circuit 3183 shown in FIG.

  The random number update circuit 3183 shown in FIG. 12A includes a counter circuit 3183a, a start value selection circuit 3183b, and a maximum value setting register 3183c. 10 shows that either the external clock signal or the internal clock signal is input to the random number update circuit 3183 as an update clock signal for updating the random number, the random number shown in FIG. Maximum value data is further input to the update circuit 3183 from the CPU 304.

  A random number (random number data) is output from the counter circuit 3183a. The initial value of this random number is set in the start value selection circuit 3183b. The initial value is set to any one of a fixed value (for example, 0), a value based on the ID number of the basic circuit 302 stored in the program management area, and a value lottery within the random number generation range. Is done.

  The counter circuit 3183a is provided with a counter in which 1 is added for each clock of the update clock signal, and a value obtained by adding the initial value of the random number input from the start value selection circuit 3183b to the value of this counter is provided. Output as a random number.

  The maximum value of the random number output from the counter circuit 3183a is set in the maximum value setting register 3183c. Note that the maximum value of the random number is set in the maximum value setting register 3183c in accordance with an instruction from the CPU 304. FIG. 12B shows a 16-bit register in which this maximum value is set. The initial value when there is no instruction for setting the maximum value from the CPU 304 is FFFFH (65535). Instead of the maximum value setting register 3183c, for example, an area for setting a maximum value may be provided in the program management area of the ROM 306, and the set maximum value may be referred to.

  When the output random number exceeds the maximum value, the counter circuit 3183a subtracts a value obtained by adding 1 to the maximum value, and then outputs this value as a random number. For example, in the case where the maximum value is 65535, if the value obtained by adding the initial value and the counter value is updated in the order of 65534, 65535, 65536, and 65537, the output random number is 65534, 65535, 0 (655536). (65535 + 1)), 1 (65537- (65535 + 1)). That is, when the maximum value is exceeded, the output random number returns to zero.

  When the value of the counter provided in the counter circuit 3183a reaches the maximum value set in the maximum value register 3183c, the counter value is cleared to 0, and the counter circuit 3183a to the start value selection circuit 3183b. A signal (circular signal) indicating that the output of the random number has been completed is output. In the start value selection circuit 3183b that has received this round signal, the initial value of the random number is updated. When the initial value updated at this time exceeds the maximum value of the random number set in the maximum value setting register 3183c, for example, a fixed value can be used, or it can be set after multiplying the current maximum value of the random number once. By using a value divided by the maximum value (65535) of the random number generation range, a value that does not exceed the maximum random number value (a value within the random number generation range) is reset as an initial value. Of course, a value within the random number generation range may be set as an initial value by using this resetting method from the beginning.

  In the present embodiment, the maximum value set in the maximum value setting register 3183c is automatically updated when the output from the counter circuit 3183a completes a cycle, but for example, when an update command from the CPU 304 is received. It may be updated.

  Here, the range of the above random number generation will be described with reference to FIGS. FIG. 13 is a diagram illustrating a range of random numbers output when the maximum value of the random number generation range is not set (default state). FIG. 14 is a diagram illustrating a range of random numbers output when a maximum value different from that in FIG. 13 is set.

  First, FIG. 13A describes the situation in the nth cycle (immediately after the (n-1) th round signal is output). FIG. 13A shows a random number generation range of 0 to 65535. Further, the initial value of the output random number is shown as the start value (X).

  A random number is updated and output from the random number update circuit 3183 for each clock of the update clock. More specifically, the start value (X) is output first, and then the random numbers updated in the order of X + 1 and X + 2 are output every clock thereafter. When the value of the random number reaches 65535, which is the maximum value of the random number generation range, the random number output next is returned to 0 by the above-described processing. Thereafter, the random numbers updated in the order of 1, 2 are output, and when the X-1 is output, this random number generation range is completed. At this time, the counter value of the counter circuit 3183a in the random number update circuit 3183 is the same as the maximum value. The start value selection circuit 3183b outputs a signal (round signal) indicating that the random number output has rounded.

  Subsequently, when one clock is input, the output of the random number update circuit 3183 enters the (n + 1) period (immediately after the nth round signal is output). The situation at the (n + 1) th cycle will be described with reference to FIG. First, the counter value of the counter circuit 3183a in the random number update circuit 3183 is cleared to zero. In the start value selection circuit 3183b, a new initial value is set. FIG. 13B shows the new initial value as the start value (X ′). A random number is output in the same flow as the flow described above based on the new initial value and the counter value of the counter circuit 3183a.

  Next, in FIG. 14A, the situation of the nth cycle (immediately after the (n-1) th round signal is output) when the maximum value smaller than the maximum value of the random number generation range shown in FIG. 13 is set. Will be described. FIG. 14A shows a random number generation range that is narrower than the random number generation range shown in FIG. 13A due to the set maximum value from 0 to 65535. Note that the range of random numbers that are not output is indicated by a left-down hatching. Further, the initial value of the output random number is shown as the start value (Y).

  Similar to the situation described with reference to FIG. 13, the random number update circuit 3183 first outputs the start value (Y), and then outputs random numbers updated in the order of Y + 1 and Y + 2 every clock. . When the value of the random number reaches the set maximum value, the random number output next is returned to 0 by the above-described processing. That is, random numbers in the range indicated by the left-down hatching are not output. Thereafter, the random numbers updated in the order of 1, 2 are output, and when the Y-1 is output, this random number generation range is completed. At this time, the counter value of the counter circuit 3183a in the random number update circuit 3183 is the same as the set maximum value. The start value selection circuit 3183b outputs a signal (round signal) indicating that the random number output has rounded.

  Subsequently, when one clock is input, the output of the random number update circuit 3183 enters the (n + 1) period (immediately after the nth round signal is output). The situation in the (n + 1) th cycle will be described with reference to FIG. As in the case described with reference to FIG. 13B, the counter value of the counter circuit 3183a in the random number update circuit 3183 is cleared to zero. In the start value selection circuit 3183b, a new initial value is set. FIG. 14B shows the new initial value as the start value (Y ′). A random number is output in the same flow as the flow described above based on the new initial value and the counter value of the counter circuit 3183a.

  In addition to appropriately setting the maximum value of the random number generation channel as described above, for example, the maximum random number value is 65535 in one random number generation channel, but the maximum random number value is 255 in another random number generation channel. For example, the random number generation range may be different for each channel. In this case, the channel may be selected according to the required random number generation range. In this case, the capacity of the maximum value setting register can be reduced and the processing load for setting the maximum value can be reduced. Furthermore, even if a plurality of maximum values that can be set in advance are set and an appropriate maximum value is selected and set from these, it is possible to reduce the capacity of the maximum value setting register and to reduce the processing load for setting the maximum value. Can be reduced.

  The random number output from the random number update circuit 3183 has been described above. Hereinafter, a modification of the random number update circuit 3183 will be described with reference to FIG. The figure shows a range in which random numbers can be acquired in a random number generation range in which a maximum value and a minimum value are set.

  Although the example of changing the maximum value of the random number generation range has been described in the examples of FIGS. 12 to 14, for example, a minimum value may be set. Further, a register for setting not only the maximum value but also the minimum value may be prepared, and as shown in FIG. 15A, the minimum value and the maximum value may be set to set the random number generation range. In addition, as shown in FIG. 15B, a plurality of random number generation ranges may be set. That is, any configuration can be used as long as the range of the output random number can be set. Further, in the above description, the example in which the output random number increases by 1 has been described for easy understanding, but other random number update methods may be used.

  Hereinafter, random numbers used in the game machine of this embodiment and main derivation sources will be described with reference to FIG. FIG. 2 is a table showing random number derivation sources used in the game machine of this embodiment. Each random number shown in this figure is used in a flowchart described later.

  First, the special figure 1 winning random numbers, the special figure 2 winning random numbers, and the universal figure winning random numbers are based on random numbers generated by the random number generation channels CH1 to CH4 of the random number generation circuit 318. This value is appropriately processed as necessary and used as these random numbers.

  The big hit special figure random number, the small hit special figure random number, and the lost special figure random number are generated in a main control unit timer interrupt process to be described later. That is, these random numbers are so-called software random numbers. Note that the initial value generating random numbers used when generating these random numbers are generated by the main control unit main process and the main control unit timer interrupt process.

  For the special figure fluctuation time determination random number and the normal figure fluctuation time determination random number, the value of the counter circuit 312 is used as a random number. In the count circuit 312 of this embodiment, in addition to the system clock of the basic circuit 302, a timeout signal from the timer circuit, a memory read / write signal, a memory request signal, an external input / output signal, and the like can be used as counter targets. . Therefore, by combining these, a value having no regularity is derived and used for the above random number.

  The production random number is generated by the main control unit main process and the main control unit timer interrupt process.

  Next, details of the internal information register 3101 provided in the interrupt control circuit 3100 shown in FIG. 6 will be described with reference to FIG. This figure shows a part of the internal information register 3101 provided in the interrupt control circuit 3100 shown in FIG.

  As described above, the internal information register 3101 has an abnormality in the period of the external clock (count clock) that determines the random number update period in the random number generation circuit 318, an abnormality in the generated random number, and the user reset that occurred immediately before. Stores reset cause information. FIG. 17A shows a range in which information indicating abnormality of the random number generation circuit 318 is stored in the internal information register 3101. This range is composed of 8 bits, and FIG. 17B shows a table showing what information each bit represents. The CPU 304 confirms the contents of the internal information register 3101 each time a timer interrupt described later is executed (step S235a in FIG. 28). This content is used to determine whether or not to perform processing such as stopping the progress of a game when an abnormality occurs. For example, the present embodiment is configured such that the winning acceptance process is not executed when an abnormality is detected by the random number generation circuit 318 (see step S235c in FIG. 28 and FIG. 30). In addition, the ball may not be launched, the payout may not be performed, or the variation timer may not be subtracted. In particular, when there is an abnormality in random number update, there is a possibility that a large current is flowing through the random number update circuit 3183 (latch-up state). Good.

  Bit number 0 is a bit indicating an abnormality of the external clock (update clock) of the random number generation circuit 318. 0 indicates no abnormality and 1 indicates an abnormality.

  Bit numbers 1 to 4 are bits indicating an abnormality of the random number generated by the random number generation circuit 318 for each channel, where 0 indicates no abnormality and 1 indicates an abnormality.

  Bit numbers 5 to 7 are not used (fixed to 0).

  When the value of the internal information register 3101 is 1, when read from the CPU 304, it is set (cleared) to 0. Since the internal information register is read by the CPU 304 at a time, when the value held in the internal information register 3101 is set to 0 (cleared), the value read after reading the value of the internal information register 3101 to the CPU 304 Can be discarded.

  Further, as described above, when either system reset or user reset processing is executed, the internal information register is set (cleared) to 0 as in the case of reading from the CPU 304. It will be.

  As described above, how the abnormality of the random number generation circuit 318 is stored has been described. Information indicating the reset factor is also stored in the internal information register 3101 as in this example. In the above description, the abnormality of the random number generation channel is represented for each channel by the bit numbers 1 to 4, but it may be represented by one bit whether an abnormality has occurred in any channel. (It may be common to all channels). In this embodiment, the internal information register 3101 is provided in the interrupt control circuit 3100, but may be provided in another circuit.

  Next, an example of abnormality detection in the frequency monitoring circuit 3182 shown in FIG. 10 will be described with reference to FIG. The figure shows an example of abnormality detection in the frequency monitoring circuit 3182. FIG. 18 shows, from the top, normal operation, abnormal operation example 1 (abnormal time 1), and abnormal operation example 2 (abnormal time 2), respectively. In these examples, in addition to the internal clock of the basic circuit 302 and the external clock (RCK) input to the random number generation circuit 318, the ratio of the cycle of the internal clock to one cycle of the external clock is shown.

  In this detection operation, the ratio of the period between the external clock and the internal clock is monitored, and a case where this ratio changes is detected as an abnormality.

  In the normal example shown in FIG. 18A, a state where the internal clock has 2.5 cycles continues during one cycle of the external clock. That is, since the ratio of the period between the external clock and the internal clock does not change, information indicating abnormality is not output.

  Next, in an operation example 1 at the time of abnormality shown in FIG. 18B (abnormal time 1), a state in which the internal clock has 4.5 cycles in one cycle of the external clock is shown. When the state shown in FIG. 18A changes to the state shown in FIG. 18B, information indicating an abnormality is output at this point.

  Next, at the beginning of the operation example 2 (abnormal time 2) at the time of abnormality shown in FIG. If the state shown in FIG. 18A is changed to the first state shown in FIG. 18C, information indicating abnormality is output at this point. Further, FIG. 18C shows a state in which the internal clock has 0.5 cycles during one external clock cycle, and a state in which the internal clock has 2.5 cycles in one external clock cycle. ing. Information indicating abnormality is output even when the ratio of the period changes.

  In the above example, when one of the external clock and the internal clock becomes abnormal, information indicating abnormality is output. That is, even when the internal clock is used as a random number update clock, an abnormality can be detected. If the ratio between the external clock and the internal clock is the same, no information indicating abnormality is output even if both frequencies are changed. In this case, for example, information indicating the frequency of the external clock or the internal clock can be stored in the program management area, and the abnormality of the external clock or the internal clock can be detected using this information. The method for detecting an abnormality of the update clock is not limited to the above-described method, and other methods may be adopted as long as the abnormality of the update clock cycle can be detected.

  Subsequently, an example of abnormality detection in the random number monitoring circuit 3184 illustrated in FIG. 10 will be described with reference to FIG. This figure is a diagram showing an example of detecting an abnormality in the random number monitoring circuit 3184. In this detection example, the random numbers before and after the update are compared every time the random number is updated, and it is checked whether or not the same random number is generated. If the same random number is generated, information indicating abnormality is output. In the example of FIG. 19A, since the same random number is not generated before and after the update, information indicating abnormality is not output. On the other hand, in the example of FIG. 19B, the same random number is generated in the middle of the update (the random number 4 is generated twice), and at this point (when the second 4 is output) Will output information indicating anomalies. In the above example, the check is performed every time the random number is updated. However, the check may be performed every predetermined cycle longer than the random number update cycle.

  As described above, in the random number generation circuit 318, information indicating abnormality is output from the frequency monitoring circuit 3182 and the random number monitoring circuit 3184 to the internal information register 3101. Further, the value of the internal information register 3101 is read by the CPU 304 at every timer interruption.

  By monitoring the abnormality of the random number generation circuit 318 using both the frequency monitoring circuit 3182 and the random number monitoring circuit 3184 as described above, there is an abnormality in the update clock frequency, but there is no abnormality in updating the random number ( An abnormal state that cannot be detected only by the random number monitoring circuit 3184) and an abnormal state in which the frequency of the update clock is normal but there is an abnormality in updating the random number can be accurately grasped. Control can be stabilized.

  In conventional game machines, fraud may be made by targeting the random numbers used in the lottery so that it is easy to derive the lottery results advantageous to the player, making it difficult to ensure the fairness of the game. ing. However, according to the gaming table of the present embodiment, since the random number generation 318 described above can grasp the abnormality of the random number used in the lottery, it can be dealt with. Can be secured.

  Note that the frequency monitoring circuit 3182 and the random number monitoring circuit 3184 continuously monitor regardless of the information stored in the internal information register 3101.

  Here, the value of the internal information register 3101 is a cycle in which the random number generated by the random number generation circuit 318 makes a round (a period required to output all the values in the random number generation range once, hereinafter, a random cycle) 20), the problem in the case of a configuration that is held and then cleared will be described with reference to FIG. This figure is a comparison of the cycle of the random number and the timer interrupt cycle. At the top of FIG. 20, a random number round cycle t1 longer than the timer interrupt cycle t4 shown at the bottom is shown. Further, in the second and third from the top in FIG. 20, random number round cycles t2 and t3 shorter than the timer interrupt cycle t4 are shown, respectively.

  As described above, the contents of the internal information register 3101 are confirmed for each timer interrupt. For example, when the random number round cycle is longer than the timer interrupt cycle t4 as in the random round cycle t1 shown in FIG. 20, this value can be read before the value held in the internal register 3101 is cleared. However, in this embodiment, since the maximum value of the random number generation range can be set, there may occur a situation where the random number cycle period is shortened accordingly. For example, when the random number round cycle is shorter than the timer interrupt cycle t4 as in the random round cycles t2 and t3 shown in FIG. 20, this value may be cleared before reading the value held in the internal register 3101. That is, the CPU 304 may not be able to acquire information indicating abnormality.

  In this embodiment, once the value of the internal information register 3101 is set, the value is held until this value is read. That is, this value is maintained regardless of whether it has returned to normal. Further, when the CPU 304 reads this value, the value of the read portion is cleared. For this reason, even if the round cycle of the random number has changed as described above, information indicating abnormality can be acquired from the internal information register 3101. If the abnormality continues after the value indicating abnormality is read, the value indicating abnormality is set again.

<Main control unit main processing>
Next, a main control unit main process executed by the CPU 304 of the main control unit 300 shown in FIG. 4 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit.

  This main control unit main process corresponds to the above-described process in the user mode, and is a process executed regardless of whether a system reset is applied or a user reset is applied. The RAM 308 of the main control unit 300 shown in FIG. 4 has a special jackpot special random number counter, a small bonus special figure 1 random counter, a lost special figure 1 random number counter, and a counter for these counters for the special figure 2. Is provided. In addition, the RAM 308 stores the number of holds in FIG. 1, the special figure 1 winning random number, the big hit special figure 1 random number, the small hit special figure 1 random number, the lost special figure 1 random number, the special figure 1 success / failure determination result, The determination result of FIG. 1, the special figure 1 variation time, and the reservation number, random number, and result for the special figure 2 are stored. In addition, the RAM 308 has separate storage units that are divided into the maximum number of areas (four in this example) that can hold the start of the determination (lottery), separately for the special figure 1 and the special figure 2. Yes. As shown below, the reserved storage unit of Special Figure 1 determines Special Figure 1 winning random numbers, Special Bonus Figure 1 random numbers, Special Bonus Figure 1 random numbers, Loss Special Figure 1 random numbers, and Special Figure 1 variation time determination. One set of five random numbers for use is stored as a set in the winning order (holding order) for each area.

  As described above, the main control unit 300 shown in FIG. 4 includes the start signal output circuit (reset signal output circuit) 340 that outputs the start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input performs reset start by a reset interrupt, and executes main control unit main processing shown in FIG. 6 in accordance with a control program stored in advance in the ROM 306.

  In step S101, initial setting 1 is performed. In this initial setting 1, the stack initial value is set to the stack pointer (SP) of the CPU 304 (temporary setting), the interrupt mask is set, the I / O 310 is initialized, various variables stored in the RAM 308 are initialized, and the like. .

  In step S103, whether or not the low voltage signal is ON, that is, the voltage value of the power supply that the voltage monitoring circuit 338 supplies to the main control unit 300 via the second sub control unit 500 by the power supply control unit 660. Is less than a predetermined value (9v in this embodiment), it is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. When the low voltage signal is on (when the CPU 304 detects that the power is cut off), this step S103 is repeatedly executed, and when the low voltage signal is off (when the CPU 304 has not detected the power supply is cut off). Then, the process proceeds to step S105. Even if the predetermined value (9 V) is not yet reached immediately after the power is turned on, step S103 is repeatedly executed until the supply voltage becomes equal to or higher than the predetermined value.

  In step S105, initial setting 2 is performed.

  FIG. 22 is a flowchart showing a flow of initial setting 2 in the main process of the main control unit.

  First, in step S1051, setting processing relating to the counter circuit 312 such as processing for setting a maximum value and a numerical value for determining an update source in the counter circuit 312 is performed. Note that setting processing related to the timer circuit 311 is also performed, such as processing for setting a numerical value for determining a cycle for executing a main control unit timer interrupt processing, which will be described later, to the timer circuit 311 at regular intervals. In step S1052, a process of outputting a clear signal from the output port to the first sub control unit 400 is performed, and the process proceeds to step S1053. In step S1053, a random number generation circuit initial setting process is performed, and in step S1054, a setting for permitting writing to the RAM 308 is performed, and the initial setting 2 is completed.

  FIG. 23 is a flowchart showing the flow of the random number generation circuit initial setting process in step S1053.

  This random number generation circuit initial setting process is an initial setting process of the random number generation circuit 318 shown in FIG. 10 performed in the above-described user mode. First, a range of random numbers (random number generation range) is set (step S1053a), and the process proceeds to step S1053b. As described above, in the random number generation circuit 318 shown in FIG. 10, the maximum width of the random number to be generated is 0 to 65535, and this maximum width becomes the default of the random number generation range. Here, FIGS. 12 to 15 are used. As described in detail, the random number generation range can be set to a range different from the default. Since the main process of the main control unit shown in FIG. 21 is a process that is executed every time reset (system reset or user reset) is performed, the setting of the random number generation range is also performed every time reset is performed. By doing in this way, the problem by abnormality of the random number update range mentioned later using FIG. 32, FIG. 33 can be prevented.

  In step S1053b, the random number register 3188 shown in FIG. 10 is read, and the read random number is discarded, and the process proceeds to step S1053c. By this processing, every time the random number generation range is reset, the random number register 3188 enters an allowable state that allows the random number to be latched. In this permissible state, even if a random number that may be abnormal remains in the random number register, it is possible to immediately update the random number, thereby preventing the use of a random number that may be abnormal.

  In the present embodiment, the random number generation circuit 318 generates a random number that is the basis of the special figure winning random number and the universal winning random number, but the output channel differs depending on the control state. That is, the random number that is the basis of the special figure winning random number is output from the channel CH1 during non-probability fluctuation (special figure low probability state), and is output from the channel CH2 during probability fluctuation (special figure high probability state). . Further, the normal winning random number is output from the channel CH3 in the normal low probability state (during non-electric support) and is output from the channel CH4 in the normal high probability state (during electric support). Note that the random number generation circuit 318 may generate the special figure winning random number itself, or may generate a random number that is the basis of the special figure winning random number. Further, the normal winning random number itself may be generated, or the random number that is the basis of the normal winning random number may be generated. In step S1053c, it is determined whether or not step S1053a and step S1053b have been executed for all four channels. If all channels have not been completed, the process returns to step S1053a for each unfinished channel. Process. Note that the setting of the random number generation range may be executed only for the channel used according to the state, or may be executed only for the channel for which the random number generation range is set. On the other hand, if all the channels have been completed, this random number generation circuit initial setting process is completed.

  In the present embodiment, when the random number generation circuit initial setting process described above is performed, the random number generation circuit 318 starts updating the random number. When a user reset is applied, the random number is updated, and the random number is generated in the new random number generation range without delay based on the update of the random number generation range in that state. In addition, when a user reset is applied, a process for stopping the update of the random number may be performed once, and a process for restarting the update of the random number may be performed after setting the random number generation range. In addition, the timer interrupt of the main control unit is prohibited at this point, and the random number generation circuit initial setting processing is performed before the timer interrupt is permitted, so even if a new random number is latched, it is used for various lotteries. The lottery process can be stabilized.

  The random number generation circuit 318 may not perform the random number generation circuit initial setting process when receiving an instruction from the CPU 304 to execute the random number generation circuit initial setting process. That is, regardless of whether or not the random number generation circuit 318 performs the random number update, the CPU 304 may be instructed to execute the random number generation circuit initial setting process. With this configuration, the analysis result of the user program and the operation of the random number generation circuit 318 do not match, making it difficult to analyze the operation of the basic circuit 302 and preventing fraud. Therefore, the operation of the basic circuit 302 is not unstable due to fraud, and the game control can be stabilized. If the operation of the basic circuit 302 is analyzed by fraud, there is a possibility that an operation advantageous to the player may be performed. However, with the above configuration, such fraud can be prevented, so that game control is stable. Can be achieved.

  Furthermore, regardless of whether or not the random number generation circuit 318 performs the random number update, if the CPU 304 is instructed to execute the random number generation circuit initial setting process, the process when the user reset is performed may be unified. it can. That is, even if the state becomes unstable after the user reset, it is not necessary to perform the branch process, so that the game control can be stabilized.

  In addition, although the above-mentioned content described the case where a user reset was applied, the same effect can be acquired also when a system reset is applied.

  In step S107 in the main process of the main control unit shown in FIG. 21, it is determined whether or not to return to the state before power interruption (before power interruption). When the basic circuit 302 is initialized, the process proceeds to the RWM clear process (step S115).

  Specifically, first, a RAM clear signal transmitted when a store clerk or the like of a game store operates the RAM clear switch 180 provided on the power supply board 182 shown in FIG. 2 (indicating that there has been an operation). If the RAM clear signal is ON (RAM clear is necessary), the process goes to step S113 to set the basic circuit 302 to the initial state. move on. On the other hand, when the RAM clear signal is OFF (when the RAM clear is not necessary), the power status information stored in the power status storage area provided in the RAM 308 is read, and the power status information is information indicating suspend. It is determined whether or not. If the power status information is not information indicating suspend, the process proceeds to step S113 to set the basic circuit 302 to an initial state. If the power status information is information indicating suspend, a predetermined area of the RAM 308 is set. A checksum is calculated by adding all 1-byte data stored in (for example, all areas) to a 1-byte register whose initial value is 0. The result of the calculated checksum is It is determined whether or not the value matches the value set in the RAM 308 (whether or not the checksum result is normal). If the checksum result is a specific value (if the checksum result is normal), the process proceeds to step S109 to return to the state before the power interruption, and the checksum result is other than the specific value. In the case (when the result of the checksum is abnormal), the process proceeds to step S113 in order to set the pachinko machine 100 to the initial state. Similarly, when the power status information indicates information other than “suspend”, the process proceeds to step S113.

  In step S109, data write-back processing is performed. In this data write-back process, the value of the stack pointer stored in the stack pointer save area provided in the RAM 308 at the time of power interruption is read and reset to the stack pointer (this setting). In addition, the value of each register stored in the register save area provided in the RAM 308 at the time of power interruption is read out and reset in each register, and then the interrupt permission is set. Thereafter, as a result of the CPU 304 executing the control program based on the reset stack pointer and registers, the pachinko machine 100 returns to the state when the power is turned off. That is, the processing is resumed from the instruction next to the instruction executed immediately before branching to the timer interrupt process (described later) immediately before the power interruption. A RAM 308 mounted on the basic circuit 302 in the main control unit 300 shown in FIG. 4 is provided with a transmission information storage area. In step S109, a power recovery command is set in the transmission information storage area. This power recovery command is a command indicating that the power has been restored to the state at the time of power-off, and is transmitted to the first sub-control unit 400 in step S231 in the timer interrupt process of the main control unit 300, which will be described later.

  In step S111, processing for starting WDT 3141 is performed. Here, activation permission of WDT 3141, setting of an initial value, and the like are performed. In the present embodiment, a numerical value corresponding to 32.8 ms is set as an initial value in WDT 3141.

  In step S113, RWM clear processing is performed. In this RWM clear process, all storage areas in the RAM 308 are initialized. In addition, setting of timer interrupt permission of the main control unit, setting of the stack initial value to the stack pointer (this setting), etc. are also performed. Further, here, a normal return command is set in the transmission information storage area provided in the RAM 308 of the main control unit 300. This normal return command is a command indicating that the RWM clear process (step S113) of the main control unit 300 has been performed. Like the power recovery command, in step S231 in the timer interrupt process of the main control unit 300, 1 is transmitted to the sub-control unit 400.

  In step S115, similarly to step S111, processing for starting WDT 3141 is performed.

  In step S117, basic random number initial value update processing is performed. Here, the basic random number corresponds to a big hit special figure random number, a small hit special figure random number, and a lost special figure random number, which are software random numbers. Note that each random number includes a random number for special figure 1 and a random number for special figure 2, but in the following description, unless otherwise noted, both will be described as a special figure without distinction. In this basic random number initial value updating process, the initial value generating random number counter for generating the initial values of the big hit special figure random number counter, the small hit special figure random number counter, and the lost special figure random number counter is updated. Each counter is provided in the RAM 308. The initial value generation random number counter is also updated in step S204 described later.

  In step S119, effect random number update processing is performed. The effect random number here is also a software random number, and this effect random number is a random number from which the effect is determined. In the present embodiment, when the lottery is executed to determine whether or not to perform a prefetch notice described later. It corresponds to the random number used. In this effect random number update process, the effect random number counter provided in the RAM 308 is updated. The effect random number counter is also updated in step S211 described later.

  The main control unit 300 repeatedly executes the processes of step S117 and step S119 except during a timer interrupt process that starts every predetermined period.

<Main control unit timer interrupt processing>
Next, a main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of the main control unit timer interrupt process.

  The main control unit 300 shown in FIG. 4 includes a timer circuit 311 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 4 ms), and the main control is triggered by this timer interrupt signal. The part timer interrupt process is started at a predetermined cycle.

  In step S201, a timer interrupt start process is performed. In this timer interrupt start process, a process of temporarily saving each register value of the CPU 304 to the stack area is performed.

  In step S203, the WDT 3141 is periodically changed to prevent the WDT 3141 interrupt from occurring when the count value of the WDT 3141 exceeds the initial setting value (32.8 ms in the present embodiment) (so as not to detect a processing abnormality). In the embodiment, the restart is performed once every about 4 ms, which is the period of the main control unit timer interrupt.

  In step S205, input port state update processing is performed. In this input port state update process, the detection signals of various sensors 320 shown in FIG. 4 including various ball detection sensors are input via the input port of the I / O 310 to monitor the presence or absence of the detection signals, and various kinds of data are stored in the RAM 308. The data is stored in a signal state storage area provided for each sensor 320. If the detection signal of the sphere detection sensor is described as an example, information on the presence / absence of the detection signal of each sphere detection sensor detected in the timer interruption process (about 4 ms before) is stored in the RAM 308 for each sphere detection sensor This information is read out from the previous detection signal storage area partitioned and stored in the RAM 308 in the previous detection signal storage area partitioned for each sphere detection sensor, and the previous timer interrupt processing (about 2 ms before) ) Is read from the current detection signal storage area provided for each sphere detection sensor in the RAM 308, and this information is read out from the previous detection signal storage area described above. To remember. Further, the detection signal of each sphere detection sensor detected this time is stored in the above-described current detection signal storage area.

  Further, in step S205, the information on the presence or absence of the detection signal of each sphere detection sensor stored in each storage area of the above-mentioned detection signal storage area, the previous detection signal storage area, and the current detection signal storage area is compared. It is determined whether or not the information on the presence or absence of detection signals for the past three times in the ball detection sensor matches the winning determination pattern information. This main control unit timer interrupt process that is repeatedly started at a very short interval of about 2 ms while one game ball passes one ball detection sensor is started several times. For this reason, every time the main control unit timer interrupt process is activated, in step S205 described above, a detection signal indicating that the same game ball has passed the same ball detection sensor is confirmed. As a result, a detection signal indicating that the same game ball has passed the same ball detection sensor is stored in each of the detection signal storage area, the previous detection signal storage area, and the current detection signal storage area. That is, when the game ball starts to pass through the ball detection sensor, there is no detection signal before, a previous detection signal, and a current detection signal. In the present embodiment, in consideration of erroneous detection of the sphere detection sensor and noise, it is determined that there is a prize when the detection signal is stored twice continuously after no detection signal. The ROM 306 of the main control unit 300 shown in FIG. 4 stores winning determination pattern information (in this embodiment, information indicating that there is no previous detection signal, that there is a previous detection signal, and that there is a current detection signal). In this step S205, information on the presence or absence of detection signals for the past three times in each sphere detection sensor is predetermined winning determination pattern information (in this embodiment, no previous detection signal, previous detection signal, current detection signal present). In the case of the general winning port 226, the variable winning port 234, the first special figure starting port 230, and the second special figure starting port 232, or the ordinary drawing starting port 228. Is determined to have passed. In other words, it is determined that there has been a winning at these winning ports 234, 230 and the starting ports 230, 232, 228. For example, when the information on the presence / absence of the detection signals for the past three matches with the above-described winning determination pattern information in the general winning opening sensor for detecting the winning at the general winning opening 226, there is a winning at the general winning opening 226. If the information on the presence / absence of detection signals for the past three times does not match the above-described winning determination pattern information, the subsequent general winnings are performed. The process branches to the subsequent process without performing the process associated with winning the prize to the mouth 226. Note that the ROM 306 of the main control unit 300 stores winning determination clear pattern information (in this embodiment, information indicating that there is a detection signal before the previous time, no previous detection signal, and no current detection signal). After it is determined that there has been a single win, it is not determined that there has been a win until the information on the presence or absence of detection signals for the past three times matches the winning determination clear pattern information in each ball detection sensor, and the winning determination is cleared. If it matches the pattern information, it is next determined whether or not it matches the winning determination pattern information.

  In step S207 and step S209, basic random number initial value update processing and basic random number update processing are performed. In these basic random number initial value update processing and basic random number update processing, the value of the initial value generation random number counter performed in step S117 is updated, and then the jackpot special figure random number used in the main control unit 300, The random number counter for generating the special figure random number for small hits and the special figure random number for lose is updated. For example, if the possible numerical range for the big hit special figure random number is 0 to 100, the value is acquired from the random number counter storage area for generating the big hit special figure random number provided in the RAM 308, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. If it is determined that the random number counter has made one round as a result of adding 1 to the acquired value, the value of the initial value generating random number counter corresponding to each random number counter is acquired and stored in the storage area of the random number counter. set. For example, a value is acquired from a random counter for generating a special jackpot random number for big hit that fluctuates in a numerical range of 0 to 100, and a result obtained by adding 1 to the acquired value is stored in a predetermined initial value storage area provided in the RAM 308. If the value is equal to the previously set initial value (for example, 7), the value is acquired as the initial value from the initial value generating random number counter corresponding to the random number counter for generating special jackpot random numbers, The initial value set this time is stored in the above-described initial value storage area in order to determine that the special counter random number counter for generating a big hit special round has been made next round. Keep it. In the present embodiment, the counter for acquiring the random number related to the special figure 1 and the counter for acquiring the random number related to the special figure 2 are separately provided, but the same counter may be used.

  In step S211, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random number used by the main control unit 300 is updated, as in step S119.

  In step S213, timer update processing is performed. In this timer update processing, the normal symbol display symbol update timer for timing the time for the symbol to be changed / stopped on the normal symbol display device 210, and the time for the symbol to be changed / stopped to be displayed on the first special symbol display device 212 are timed. Special symbol 1 display symbol update timer for performing, special symbol 2 display symbol update timer for measuring the time for the symbol to be changed and stopped on the second special symbol display device 214, a predetermined winning effect time, a predetermined opening time Various timers including a timer for measuring a predetermined closing time, a predetermined end effect period, and the like are updated.

  In step S215, winning prize counter update processing is performed. In this winning opening counter update process, when winning holes 234, 230 and starting holes 230, 232, 228 are won, the RAM 308 stores the winning ball number storage area provided for each winning hole or for each starting hole. The value is read out, 1 is added, and the original prize ball number storage area is set.

  In step S217, a winning acceptance process is performed. In this winning acceptance process, if there is a winning at the first special figure starting port 230 and the number of special figure 1 variable games on hold is less than a predetermined number (4 in this embodiment), a predetermined Get startup information. That is, if the number of holdings is less than the predetermined number, a hardware random number that is the basis of the special figure 1 winning random number is obtained from the random number generation circuit 318 shown in FIG. 4 and processed to obtain the special figure 1 winning random number. . This point will be described in more detail later. Also, the big hit special figure 1 random number, the small hit special figure 1 random number, and the lost special figure 1 random number are acquired from a random number counter storage area provided in the RAM 308. Special jackpot special figure 1 random numbers, small hit special figure 1 random numbers, and lost special figure 1 random numbers are values obtained by processing software random numbers derived from software random number counters provided in the RAM 308 (software random number value + R register value). Value + 1). Further, the special figure 1 variation time determination random number is acquired from the counter circuit 312 shown in FIG. The combination of the random number generation circuit 318, the counter circuit 312 and the software random number counter provided in the RAM 308 and the main control unit 300 that performs random number processing shown in FIG. 4 generates and derives start information. This corresponds to an example of information deriving means (first starting information deriving means, second starting information deriving means). If attention is paid to the generation of hardware random numbers, the random number generation circuit 318 or the counter circuit 312 shown in FIG. 4 generates start information, and start information generation means (first start information generation means, second start information generation means, Corresponds to an example of the starting information generating means). The various random numbers (starting information) acquired here are stored as a set of starting information in a vacant area corresponding to the winning order (holding order) of the holding storage unit of FIG. . The reserved storage unit of FIG. 1 stores the start information acquired when a game ball enters the first special figure start port 230 (first start area) up to a predetermined first upper limit number (here, four). This corresponds to the first start information storage means that can be stored. At this time, various random numbers (starting information) may be temporarily stored in a temporary area provided in the RAM 308, and the value stored in the temporary area may be stored in the holding storage unit of FIG. 1 may be used as the first start-up information storage unit, or the reserved storage unit and the temporary area in FIG. 1 may be used as the first start-up information storage unit. Further, the CPU 304 of the main control unit 300 adds 1 to the value of the number of holdings in FIG. 1 stored in the RAM 308, and the number of holdings in FIG. Therefore, the CPU 304 of the main control unit 300 corresponds to an example of a holding unit. As for special figure 2, each random number which is start information is acquired as in special figure 1, and the obtained random number is similarly stored as a set of start information in the holding storage unit of special figure 2 provided in RAM 308. Further, 1 is added to the value of the number of holdings in FIG. 2 stored in the RAM 308. The reserved storage unit of the special figure 2 stores the start information acquired when the game ball enters the second special figure start port 232 (second start area) up to a predetermined second upper limit number (here, four). This corresponds to a possible second starting information storage means. At this time, various random numbers (starting information) may be temporarily stored in a temporary area provided in the RAM 308, and the value stored in the temporary area may be stored in the holding storage unit of FIG. The starting information storage means may be used, or the holding storage unit and the temporary area of FIG. 2 may be used as the second starting information storage means.

  In addition, when it is detected that a ball has passed through the general figure starting port 228 and the number of pending custom figure variable games is less than a predetermined number (4 in this embodiment), the timing is as follows. 4 is obtained from the random number generation circuit 318 shown in FIG. 4, and is stored in a random number storage area different from that for the special figure provided in the RAM 308. The point that the normal winning random number is acquired from the random number generation circuit 318 will also be described later.

  In this winning acceptance process, a predetermined ball detection sensor detects a winning (winning) at the first special figure starting port 230, the second special figure starting port 232, the ordinary drawing starting port 228, or the variable winning port 234. In such a case, the transmission information to be transmitted to the first sub-control unit 400 includes the winnings of the first special figure starting port 230, the second special figure starting port 232, the general drawing starting port 228, and the variable winning port 234. ) Is set to receive winning information.

  Whether the start information of the special figure or the start information of the usual figure, if the number of holdings is equal to or greater than the predetermined number, the start information is not acquired and the process proceeds to step S219.

  In step S219, a payout request number transmission process is performed. The output schedule information and the payout request information output to the payout control unit 600 shown in FIG. 4 are composed of 1 byte, strobe information (indicating that data is set when ON), bit 6 Power-on information (if turned on, indicates that this is the first command transmission after power-on), bits 4-5 indicate the current processing type for encryption (0-3), and bits 0-3 indicate encryption The number of payout requests after processing is shown.

  In step S221, a normal state update process is performed. This normal state update process performs one of a plurality of processes corresponding to the normal state. For example, in the normal state update process in the middle of the normal symbol display (the above-described general symbol display symbol update timer value is 1 or more), the 7-segment LED constituting the normal symbol display device 210 is repeatedly turned on and off. Turns off drive control. By performing this control, the normal symbol display device 210 performs a usual fluctuation display (ordinary figure fluctuation game).

  Also, in the normal state update process at the timing when the normal symbol change display time has elapsed (the timing at which the value of the general symbol display symbol update timer has changed from 1 to 0), if the hit flag is on, the hit symbol is displayed. The normal symbol display device 210 is controlled so that the 7-segment LED constituting the normal symbol display device 210 is turned on / off, and when the hit flag is off, the normal symbol display device 210 is configured to display the lost symbol display mode. 7 segment LED on / off drive control is performed. Further, the RAM 308 of the main control unit 300 is provided with a setting area for performing various settings in various processes, not limited to the normal state update process. Here, the above-described lighting / extinguishing drive control is performed, and the setting area is set to indicate that the normal stop display is being performed. By performing this control, the normal symbol display device 210 determines the symbol of either one of the winning symbols (the common symbol A shown in FIG. 5C) or the lost symbol (the universal symbol B shown in FIG. 5C). Display. Thereafter, information indicating the stop period is set in a storage area of a normal stop time management timer provided in the RAM 308 in order to maintain the display for a predetermined stop display period (for example, 500 msec). With this setting, the symbol that has been confirmed and displayed is stopped and displayed for a predetermined period, and the player is notified of the result of the normal game.

  Further, if the result of the usual figure variable game is a hit, the usual figure hit flag is turned on as will be described later. When the usual figure hit flag is on, in the usual figure state update process at the timing when the predetermined stop display period ends (when the usual figure stop time management timer value changes from 1 to 0), The normal operation is set in the setting region, and the blade member 2321 is opened to the solenoid (332) for opening and closing the blade member 2321 of the second special figure starting port 232 for a predetermined opening period (for example, 2 seconds). And a signal indicating the open period is set in the storage area of the blade open time management timer provided in the RAM 308. The CPU 304 of the main control unit 300 that performs the opening control of the pair of blade members 2321 in this way corresponds to an example of a variable start region control unit that performs variable start region control. On the other hand, if it is in the non-electric support state, in the setting region of the RAM 308, the normal operation is not set, and no signal is given to the solenoid (332) for opening and closing the blade member 2321 of the second special figure start port 232. Is not output. By doing so, the blade member 2321 remains closed. Note that a signal for maintaining the blade member 2321 in the closed state may be output without fail.

  In the case of the electric support state, in the process starting at the timing when the predetermined opening period ends (the timing when the value of the blade opening time management timer is changed from 1 to 0), the predetermined closing period (for example, 0.1 second), a signal for holding the blade member 2321 in a closed state is output to the solenoid (332) for opening and closing the blade member 2321, and the valve is closed in the storage area of the blade closing time management timer provided in the RAM 308. Set information indicating the period.

  In the case of the electric support state, in the normal state update process that starts at the timing when the predetermined closing period ends (the timing when the value of the blade closing time management timer changes from 1 to 0), In the setting area, set “Normal” inactive. Further, if the result of the usual figure variable game is lost, the usual figure lose flag is turned on as will be described later. When the usual figure loss flag is on, even in the usual figure state update process at the timing when the above-described predetermined stop display period ends (when the value of the usual figure stop time management timer is changed from 1 to 0), In the setting area of the RAM 308, normal operation inactive is set. In the general state update process in the case where the general map is not operating, nothing is done and the process proceeds to the next step S223.

  Subsequently, in the step S223, a general drawing related lottery process is executed.

  FIG. 25A is a flowchart showing the flow of the general drawing related lottery process.

  In the general drawing related lottery process shown in FIG. 25A, first, it is determined whether or not there is general drawing hold information (step S2231). Here, the general map hold information refers to the number of hold of the general map. In other words, here, it is determined whether or not the number of pending variable games is one or more. In addition, even if it does not have the usual number of reservations as data, for example, a random number corresponding to the reservation (a normal winning random number) may be recognized as the general reservation information. If there is no general map hold information, this general drawing related lottery process is terminated, and if there is general map hold information, the process proceeds to step S2232. In step S2232, it is determined whether or not the usual figure variable game is being performed. If it has been performed, the usual figure related lottery process is terminated, and if not, the process proceeds to step S2233. In step S2233, it is determined whether or not the opening / closing control of the second special figure starting port 232 is being performed (whether or not the normal map is operating). If it is not normally operated, the process proceeds to step S2234.

  In step S2234, a random number lottery based on the regular winning random number stored in the random number storage area is performed.

  FIG. 25B is a diagram showing a general drawing lottery table. This table is stored in the ROM 306 of the main control unit 300.

  The CPU 304 of the main control unit 300 takes out the normal winning random number from the random number storage area of the RAM 308, refers to the short time flag, and if the short time flag is on, it is in a high probability state (during electric support) Subtracting the high-probability common-plan winning data from the common-lot winning random number, if a carry occurs (if the value of the general-plan winning data is larger than the normal winning random number), it is determined to be a general winning and a carry occurs. If you don't, you will lose your usual figure. That is, the normal winning random number range is 0-9. In the normal high probability state, the normal winning random number is output from the channel CH4 of the random number generation circuit 318 shown in FIG. In this channel CH4, a random number generation range of 0 to 9 is set in the setting of the random number generation range (step S1053a) in the random number generation circuit initial setting process shown in FIG. The range that can be taken is 0-9. Therefore, the probability of winning the normal drawing in the normal high probability state is 1/1. On the other hand, if the time flag is off, it is in the low probability state (non-powered support), so the winning symbol in the low probability state is the same as the data in the high probability state from the acquired random number. If the data is pulled and a carry occurs (when the value of the win-winning data is larger than the normal-winning random number), the win-winning is determined. If no carry occurs, the win-win is lost. That is, even in the normal figure low probability state, the normal figure winning random number range is 0-9. In the normal low probability state, the normal winning random number is output from the channel CH3 of the random number generation circuit 318 shown in FIG. For this channel CH3, a random number generation range of 0 to 999 is set in the setting of the random number generation range (step S1053a), and the range that can be taken by the normal winning random number in the normal low probability state is 0 to 999. Therefore, the probability of winning the normal figure in the normal figure low probability state becomes 1/100.

  In this embodiment, by limiting the range (random number generation range) that the normal winning random numbers can take from the default 0 to 65535 to 0 to 999, the big hit probability can be reduced to 1/100. In addition, the common figure winning data can be set to the same value in the common figure high probability state and the common figure low probability state. Determining the probability without limiting the random number generation range may lead to an increase in development man-hours and may cause erroneous probability design. In particular, the complexity becomes more noticeable when lottery is performed a plurality of times based on one opportunity. Therefore, limiting the random number generation range can reduce the development man-hours and stabilize the lottery process. In addition, it can be said that sharing the common figure winning data in the common figure high probability state and the common figure low probability state can reduce the development man-hours and stabilize the lottery process.

  When the regular drawing lottery is won, the hit flag provided in the RAM 308 is set to ON. In case of losing (unfair), the winning flag is set to OFF. Regardless of the result of the general drawing lottery, a random number for determining the normal variation time is acquired from the counter circuit 312 shown in FIG. One time for variably displaying the normal map on the figure display device 210 is selected, and this variable display time is stored as a normal map variable display time in the normal time variable time storage area provided in the RAM 308. Note that the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 308. Each time step S2234 is executed, the number of pending custom figure variable games is stored. The value obtained by subtracting 1 from is re-stored in the usual figure number-of-holds storage area. In addition, acquisition of the random number for determining the normal figure change time from the counter circuit 312 may be performed at the time of winning a prize in the general figure start port 228.

  In step S2235, the normal winning lottery used in the previous general drawing lottery is deleted from the random number storage area described above, and this general drawing related lottery process ends.

  Subsequently, special figure prefetching processing (step S225) is executed. In this prefetching process, first, the special figure 1 winning random number in the special memory 1 of FIG. 1 provided in the RAM 308 is prefetched, or the special figure 2 winning random number in the special memory 2 of FIG. 2 is prefetched. Note that prefetching here means that the start information is read first before the validity determination (final lottery), but in the subsequent prefetching processing, the word “prefetching” is referred to as the result of the predetermined (correction determination (final lottery)). ) May be used to mean read. In this step S225, a pre-judgment table having the same contents as the contents of the special figure lottery table shown in FIG. 27 (a) used in the special figure related process (step S229) described later is used, based on the pre-read special figure winning random number. Pre-determination is performed. In the special figure related process, the special figure lottery table is used again to determine whether or not the special figure variable game is successful, and the determination result here is only the result of the preliminary determination. In the pre-judgment determination, a result of “big hit” or a result other than “big hit” is derived, and in the case of a result of “big hit”, the big hit in the reserved storage unit of FIG. The special figure 1 random number is prefetched, or the big hit special figure 2 random number in the reserved storage unit of the special figure 2 is prefetched. Subsequently, using the pre-determination table having the same content as the content of the stop symbol lottery table shown in FIG. 27 (b) used in the special symbol related process in step S229, the special symbol stop symbol based on the prefetched special bonus random number Make a prior judgment. In the special symbol related process, the special symbol stop symbol lottery table is used again, and the special symbol stop symbol lottery is performed again, and the determination result here is a preliminary determination result. In this way, when the stop symbol of the special figure is determined in advance, a lottery to determine whether or not to perform the prefetch notice is performed. This pre-reading notice indicates that the result of the success / failure determination performed in the special drawing-related lottery process before the special figure-related lottery process (step S229) is executed, that is, before the determination of success / failure is performed. 15R big hit (15R special big hit or 15R big hit). The pre-reading notice here is a fake pre-reading notice that gives a false notice as if it was a big hit of 15R even if the pre-determined result of the stop symbol is not a big hit of 15R (Special Figure A or Special Figure B) Is also included. In other words, the pre-reading notice indicates that there is a possibility that the result of the success / failure determination will be a 15R jackpot, an advance notification that suggests to the player, or an advance notice that the player expects that the result of the success / failure determination will be a 15R jackpot. It can be said that it is information. An effect random number (for example, a possible range is 0 to 99) is acquired from an effect random number counter provided in the RAM 308 at the timing of performing the pre-reading notice execution availability lottery, and the execution availability lottery is performed based on the acquired effect random number. In addition, the prior determination result of the stop symbol may be transmitted to the first sub-control unit 400, and the first sub-control unit 400 may perform this execution availability lottery.

  Next, the special figure state update process (step S227) for each of the special figure 1 and the special figure 2 is performed. First, the special figure state update process for the special figure 2 is performed, and then the special figure state for the special figure 1 is performed. Perform figure state update processing. In the special figure 2 state update process, one of the following eight processes is performed according to the state of the special figure 2. For example, in the special figure 2 state update process in the middle of the special figure 2 fluctuation display (the value of the above-mentioned special figure 2 display symbol update timer is 1 or more), the 7-segment LED constituting the second special symbol display device 214 is turned on. Performs lighting / extinguishing drive control that repeatedly turns off. By performing this control, the second special symbol display device 214 performs the variable display of the special figure 2 (special figure 2 variable game).

  In addition, predetermined transmission information indicating that the general command rotation start setting transmission process is executed in the command setting transmission process (step S231) is additionally stored in the transmission information storage area, and the process ends.

  In addition, the RAM 308 of the main control unit 300 includes 15R big hit flag, 2R big hit flag, first small hit flag, second small hit flag, first lose flag, second lose flag, probability change flag, and hourly flag. Is prepared. In the special figure 2 state update process starting at the timing when the special figure 2 variable display time has passed (the timing when the value of the special figure 2 display symbol update timer is changed from 1 to 0), the special figure in the special figure related lottery process to be described later Based on the determination result (stop pattern mode of the special figure), the 7 segment LED constituting the second special figure display device 214 is controlled to be turned on / off, and the special figure 2 stop display is being displayed in the setting area of the RAM 308. Set to represent. By performing this control, the second special symbol display device 214 has a 15R special jackpot symbol (special symbol A), a 15R jackpot symbol (special symbol B), a 2R special jackpot symbol (special symbol C), and a sudden time shortening symbol (special symbol). Figure D), hidden probability variation (special E), suddenly normal (special F), first small hit (special G), second small (special H), first loss (special) One of the symbols (Fig. I) and the second lost symbol (special symbol J) is confirmed and displayed. After that, information indicating the stop period is set in the storage area of the special figure 2 stop time management timer provided in the RAM 308 in order to maintain the display for a predetermined stop display period (for example, 500 milliseconds). With this setting, the specially displayed special figure 2 is stopped and displayed for a predetermined period, and the result of the special figure 2 variable game is notified to the player. Further, when a value is set in the electric support number storage unit provided in the RAM 308, if the value is 1 or more, 1 is subtracted from the shortest number of times, and the subtraction result becomes 1 to 0. In this case, if the special figure probability is not changing, the time reduction flag is turned off. Further, the hourly flag is turned off during the big hit game or the small hit game. That is, the CPU 304 of the main control unit 300 shifts to the non-electric support state (first entry rate control state) when the big hit gaming state and the small hit gaming state (second control state).

  In addition, a predetermined transmission information indicating that a general command rotation stop setting transmission process is executed in a command setting transmission process (step S231), which will be described later, is additionally stored in the above-described transmission information storage area, and a pattern for stopping the variable display is displayed. Special figure 2 identification information indicating that it is special figure 2 is additionally stored in the RAM 308 as information to be included in command data, which will be described later, and the processing is terminated.

  If the result of the special figure 2 variable game is a big hit, the big hit flag is turned on. When the jackpot flag is on, in the special figure 2 state update process at the timing when the predetermined stop display period ends (the timing when the special figure 2 stop time management timer value changes from 1 to 0), the RAM 308 In the setting area, the special figure 2 is in operation and waits for a predetermined winning effect period (for example, 3 seconds), that is, a period during which an image for notifying the player that the big win by the decorative symbol display device 208 is started is displayed. Therefore, information indicating the winning effect period is set in the storage area of the special figure 2 standby time management timer provided in the RAM 308. Further, 5H is additionally stored as transmission information (command type) in the transmission information storage area described above in order to execute the general command winning effect setting transmission process in the command setting transmission process (step S231).

  Further, in the special figure 2 state update process that starts at the timing when the predetermined winning effect period ends (the timing when the value of the special figure 2 standby time management timer changes from 1 to 0), a predetermined release period (for example, 29 seconds) Alternatively, the door member 2341 is opened to the solenoid (332) for opening and closing the door member 2341 of the variable prize opening 234 until a winning of a predetermined number of balls (for example, 10 balls) is detected at the variable prize opening 234. In addition to outputting a signal to be held at the same time, information indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 308. Further, 7H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize opening release setting transmission process in the command setting transmission process (step S231).

  In the special figure 2 state update process that starts at the timing when the predetermined opening period ends (the timing when the door opening time management timer value changes from 1 to 0), the predetermined closing period (for example, 1.5 seconds) A signal for holding the door member 2341 in a closed state is output to the solenoid (332) for opening and closing the door member 2341 of the variable prize opening 234, and a closing period is stored in the storage area of the door closing time management timer provided in the RAM 308. Set the information indicating. In addition, predetermined transmission information indicating that the special winning opening closing setting transmission process is executed in the command setting transmission process (step S231) is additionally stored in the transmission information storage area.

  In addition, in the special figure 2 state update process that starts at the timing when the door member opening / closing control is repeated a predetermined number of times (15 rounds or 2 rounds in this embodiment) and finished, a predetermined end effect period (for example, 3 seconds) In other words, the effect standby period is stored in the storage area of the effect standby time management timer provided in the RAM 308 in order to set to wait for a period during which an image for informing the player that the big hit by the decorative symbol display device 208 is to be ended is displayed. Set the information indicating.

  As described above, the CPU 304 of the main control unit 300 corresponds to an example of variable winning control means for performing change control of the open / closed state of the door member 2341 of the variable winning opening 234 during the big hit gaming state. The ROM 306 of the main control unit 300 stores an opening / closing pattern of the door member 2341 of the variable prize opening 234, and the CPU 304 of the main control unit 300 responds to the determination of whether or not the special figure variable game is successful from the ROM 306. Get the open / close pattern.

  Further, the CPU 304 of the main control unit 300 sets the probability variation flag and the time reduction flag provided in the RAM 308 to be on simultaneously with the end of the big hit game, based on the stop symbol form represented by the special figure determination result. That is, the CPU 304 of the main control unit 300 sets both the probability variation flag and the time reduction flag to ON when the special figure determination result is “special figure A” or “special figure C” in the special figure lottery process described later. . When the special figure determination result is “special figure E”, only the probability variation flag is set to ON among the probability variation flag and the time reduction flag. Furthermore, when the special figure determination result is “special figure B” or “special figure D”, only the short time flag is set to ON among the probability variation flag and the short time flag, and the electric support number storage unit provided in the RAM 308 is set. Set power support 100 times. When the probability variation flag is set to ON, it is in a special figure high probability state (during probability fluctuation), and is a state in which the probability of winning a big hit after the big hit game is high (a special figure high probability state). On the other hand, if the probability variation flag is not set to ON (set to OFF), it is a special figure low probability state. Therefore, the setting state of the probability variation flag affects the result of the determination of success / failure (special drawing lottery). In addition, when the time reduction flag is set to ON, it is in an electric support state, the electric chew is easy to open (for example, easy to hit), the opening time based on one hit is long, and the number of times of opening based on one hit is large. The variable starting area control is performed so as to be advantageous to the player. On the contrary, if the time reduction flag is set to OFF, it is in a non-electric support state, and the variable start area control is performed so as to be disadvantageous to the player. Therefore, the setting state of the time reduction flag also affects the variable start area control. Therefore, information indicating the setting state of the probability variation flag and / or the time reduction flag corresponds to an example of game control information, and the CPU 304 of the main control unit 300 corresponds to an example of game control information determination means.

  Furthermore, 6H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command end effect setting transmission process in the command setting transmission process (step S231).

  Also, in the special figure 2 state update process that starts at the timing when the predetermined end production period ends (when the production standby time management timer value changes from 1 to 0), the special figure 2 is not activated in the setting area of the RAM 308. Set medium. Furthermore, if the result of the special figure 2 variable game is a loss, the loss flag is turned on. When the lost flag is on, even in the special figure 2 state update process at the timing when the predetermined stop display period described above ends (the timing when the special figure 2 stop time management timer value changes from 1 to 0), In the setting area of the RAM 308, special figure 2 inactive is set. In the special figure 2 state update process when the special figure 2 is not in operation, nothing is done and the process proceeds to the next process.

  When the special figure 2 state update process is completed, the special figure 1 state update process is performed. In the special figure 1 state update process, each process described in the special figure 2 state update process is performed according to the state of the special figure 1. Each process performed in the special figure 1 state update process is the same as the process in which “special figure 2” in the contents described in the special figure 2 state update process is replaced with “special figure 1”. Omitted. The order of the special figure 2 state update process and the special figure 1 state update process may be reversed.

  When the special figure state update process in step S227 is completed, a special figure related lottery process for each of special figure 1 and special figure 2 is performed. The CPU 304 of the main control unit 300 that executes the special figure related lottery process corresponds to an example of the determination unit. The main control unit 300 first performs the process for the special figure 2 (the special drawing 2 related lottery process), and then performs the process for the special figure 1 (the special figure 1 related lottery process). As described above, the main control unit 300 performs the special figure 2 related lottery process before the special figure 1 related lottery process, so that the game ball enters the first special figure start port 230 at the same timing. The start information is acquired and the start information is acquired based on the fact that the game ball has entered the second special figure start port 232, the special condition 2 variable game start conditions, and the special figure 1 variable game start. Even if the conditions are satisfied at the same time, or if both the special figure 2 variable game start condition and the special figure 1 variable game start condition are satisfied, the special figure 2 variable game is changing first. Figure 1 Floating game does not start to fluctuate. That is, the pachinko machine 100 according to the present embodiment performs special figure 2 priority fluctuation, and the lottery based on the winning at the second special figure start port 232 (determination of special figure 2) is determined as the first special figure start. This is prioritized over a lottery based on winning a prize in the mouth 230 (a determination of success / failure in FIG. 1). In other words, in the pachinko machine 100 of the present embodiment, when a game ball enters the first special start area, the random numbers are stored in the first random number storage area up to the maximum number of reservations, and the game is stored in the second special start area. When a ball wins, a random number is stored in both the first random number storage area and the first random number storage area, and the winning random number storage area that stores random numbers up to the maximum number of reservations in the second random number storage area In this case, the random number is stored in the second random number storage area regardless of the time when the random number is stored in the first random number storage area and the time when the random number is stored in the second random number storage area. If the random number is determined based on the random number, and the random number is not stored in the first random number storage area and the random number is stored in the second random number storage area, the second random number Based on random numbers stored in the storage area If the random number is not stored in the second random number storage area and the random number is stored in the first random number storage area, it is stored in the first random number storage area. In this case, a determination unit is provided for determining whether or not the image is correct based on the random number. In addition, the main control unit 300 notifies the result of the jackpot determination of the special figure variable game by the first special figure display device 212 or the second special figure display device 214, and wins a prize to the second special figure start port 232. Based on the determination result, the start information of FIG. 1 is used as the start information in which the determination result is not performed. In the state where only the start information of the special figure 1 of the start information of the special figure 2 remains, and the start information of the special figure 2 is newly stored, the newly stored start of the special figure 2 The notification of the result of the determination based on the information is performed prior to the notification of the result of the determination based on the startup information of FIG. Further, the start information acquisition means for acquiring start information, when start information is stored in both of the first start information storage means and the second start information storage means, the second start information When starting information is acquired from the storage means and the starting information is stored in one of the first starting information storing means and the second starting information storing means, the starting information is stored. The starting information is obtained from the information storage means. Note that the special figure 2 related lottery process may be performed first after the special figure 2 state update process, then the special figure 1 state update process may be performed, and then the special figure 1 related lottery process may be performed.

  FIG. 26 is a flowchart showing the flow of the special drawing related lottery process. In the special figure-related lottery process shown in FIG. 26, special figure 1 and special figure 2 are shown without being distinguished, but first, the process from step S2291 to step S2296 is performed on special figure 2, and thereafter, special figure 1 is processed. The process from step S2291 to step S2296 is performed. Here, it demonstrates without distinguishing special figure 2 and special figure 1. FIG.

  In the special figure-related lottery process shown in FIG. 26, first, it is determined whether or not there is special figure holding information (step S2291). Here, special figure hold information refers to the number of special figure hold. That is, here, it is determined whether or not the number of special figure variable games that are on hold is one or more. For example, a random number corresponding to a hold (a special figure winning random number) may be recognized as the special figure hold information without having the number of special figure hold as data. If there is no special figure hold information, the special figure related lottery process is terminated, and if there is special figure hold information, the process proceeds to step S2292. In step S 2292, it is determined whether or not the special figure display device (212, 214) is in the special figure variation display or in the stop display. The related lottery process ends, and if none of the displays is in progress, the process proceeds to step S2293. In step S2293, it is determined whether or not the special figure is in operation. If the special figure is in operation, the special figure-related lottery process ends. If the special figure is inactive, the process proceeds to step S2294.

  In step S2294, special drawing lottery processing is performed. Here, first, a special set of random numbers (special figure winning random number, big hit special figure random number, small hit special figure random number, Take out the special figure random number for losing and the random number for determining the special figure fluctuation time), and transfer the starting information (set of random numbers) still stored in the reserved storage part from the currently stored area to the next area . That is, if the starting information stored in the past is taken out from the reserved storage unit of the special figure and the starting information is stored in the reserved storage unit of the special figure, the Nth oldest starting information is stored in the reserved storage unit of the special figure 2 Is set as the (N-1) oldest starting information. Also, 1 is subtracted from the pending number stored in the RAM 308. One set of random numbers (special figure winning random number, big hit special figure random number, small hit special figure random number, lose special figure random number, and special figure variable time determination random number) are taken out from the special figure holding storage unit of the RAM 308. The CPU 304 of the main control unit 300 that performs processing corresponds to an example of the start information acquisition unit.

  FIG. 27A shows a special drawing lottery table. This table is stored in the ROM 306 of the main control unit 300.

  When the CPU 304 of the main control unit 300 retrieves the start information from the holding storage unit of the RAM 308, the CPU 304 refers to the probability variation flag. If the probability variation flag is ON, the probability variation is in progress (the special figure high probability state). If the special figure jackpot winning data with probability fluctuation is subtracted from the figure winning random number and carry occurs (if the value of the special figure winning data is larger than the special figure winning random number), the special figure jackpot is won and the carry occurs If not, the special figure jackpot will not be selected. That is, the special figure big hit winning random number range is 0 to 124. During the probability variation, the random number that is the basis of the special figure winning random number is output from the channel CH2 of the random number generation circuit 318 shown in FIG. In this channel CH2, a random number generation range of 0 to 4999 is set in the setting of the random number generation range (step S1053a) in the random number generation circuit initial setting process shown in FIG. The range obtained is 0-4999. Therefore, the winning probability of the special figure jackpot during the probability change is 1/40. On the other hand, if the probability variation flag is off, it means that non-probability fluctuation is in progress (special figure low probability state). On the other hand, if a carry occurs (when the value of the special figure winning data is larger than the special figure winning random number), the special figure big hit is won, and if no carry occurs, the special figure big hit is not selected. That is, the special figure big hit winning random number range is 0 to 124 even during non-probability fluctuation. During non-probability fluctuation, the random number that is the basis of the special figure winning random number is output from the channel CH1 of the random number generation circuit 318 shown in FIG. In this channel CH1, a random number generation range of 0 to 49999 is set in the setting of the random number generation range (step S1053a), and the range that can be taken by the special figure winning random number during non-probability variation is 0 to 49999. Therefore, the winning probability of the special figure jackpot during non-probability fluctuation is 1/400.

  In the present embodiment, by limiting the range (random number generation range) that the special figure winning random number can take from the default 0 to 65535 to 0 to 49999, the jackpot probability can be reduced to 1/400. Further, the special figure big hit winning data can be set to the same value during the probability fluctuation and the non-probability fluctuation. Determining the probability without limiting the random number generation range may lead to an increase in development man-hours and may cause erroneous probability design. In particular, the complexity becomes more noticeable when lottery is performed a plurality of times based on one opportunity. Therefore, limiting the random number generation range can reduce the development man-hours and stabilize the lottery process. In addition, it can be said that sharing the special figure big hit winning data during the probability fluctuation and the non-probability fluctuation can reduce the development man-hours and stabilize the lottery process.

  In FIG. 27A, only the special figure big hit lottery table is shown, but a predetermined value is prepared as the winning data for the special figure small hit. The CPU 304 of the main control unit 300 subtracts the special figure big hit winning data from the acquired special figure winning random number, and when no carry occurs (when the value of the special figure winning data is smaller than the special figure winning random number), This time, if the special figure small win winning data is subtracted from the value obtained by subtracting the special figure big hit winning data, and a carry occurs here (if the special figure small winning data is larger than the special figure winning random number) If you win a small figure and no carry occurs, you will lose. It is also possible to separately provide lost winning data. In this way, the special chart “big hit”, “small hit”, and “losing” are determined, and the determination result is obtained as the special figure determination result. The number of special figure variable games that are held is stored in the special figure variable number storage area provided in the RAM 308, and the number of special figure variable games that are held each time step S2294 is executed. The value obtained by subtracting 1 from is re-stored in this special figure holding number storage area.

  Next, in the special figure related lottery process shown in FIG. 26, a special figure stop symbol is drawn using software random numbers based on the special figure success / failure determination result (step S2295).

  FIG. 27B is a diagram showing a stop symbol lottery table. This table is also stored in the ROM 306 of the main control unit 300. In the stop symbol lottery table, symbol winning data corresponding to the stop symbol mode of the special symbol (see FIG. 5A) is defined for each success / failure determination result. In FIG. 5B, the winning probability is also shown.

  When the determination result is a big hit, the CPU 304 of the main control unit 300 determines a special jackpot random number for a big hit out of one set of random numbers previously acquired from the reserved storage unit of the RAM 308 (a possible numerical range is 0 to 0). 99) from special figure A, special figure B, ... special figure F, the symbol winning data corresponding to each stop symbol is gradually subtracted, and the stop symbol when a carry occurs is used as the special symbol determination result. . If the result of the determination is a small hit, a special hit random number for a small hit (a numerical range that can be taken is 0 to 99) out of one set of random numbers previously acquired from the reserved storage unit of the RAM 308. If the symbol winning data of Fig. G is drawn and a carry occurs, "Special Illustration G" is won, and if no carry occurs, the special drawing H is further subtracted from the value obtained by subtracting the symbol winning data of Special Illustration G. The symbol winning data is drawn, and since a carry occurs here, “Special Figure H” is won. Note that before drawing the symbol winning data of the special figure H, it may be determined that the “special figure H” has been won. In this way, when the determination result is a small hit, “special figure G” or “special figure H” is determined as the special figure determination result. Further, if the determination result is a loss, a special figure random number for loss (a possible numerical range is 0 to 99) out of one set of random numbers previously acquired from the storage unit of the RAM 308 will be special figure I. If a carry occurs, the special symbol I will be selected, and if no carry occurs, the special symbol J will be further subtracted from the value obtained by subtracting the special symbol I symbol winning data. The winning data is drawn, and here a carry occurs, so “Special Figure J” is won. Here, it may be determined that “Special Figure J” has been won before drawing the symbol winning data of Special Figure J. In this way, when the determination result is lost, “Special Figure I” or “Special Figure J” is determined as the special figure determination result. Note that the first sub-control unit 400 determines a stop symbol pattern that is a combination of decorative symbols according to the special symbol determination result determined here.

  Further, a special figure variation time determination random number (possible numerical range is 0 to 255) of the random numbers for one set previously acquired from the reserved storage unit of the RAM 308 is acquired, and the acquired special figure variation time determination random number is acquired. Is used to select one time (special figure fluctuation time) during which the special figure is variably displayed on the special figure display device (212, 214) from among a plurality of fluctuation times based on the special figure determination result. In addition, in the 1st sub control part 400, the production | presentation aspect of the decoration symbol display apparatus 208 according to the special figure change time determined here is determined.

  In step S2296, the one set of random numbers previously acquired from the reserved storage unit of the RAM 308 is erased, and this special drawing related lottery process ends.

  In step S231 performed following the special figure related lottery process in step S229, a command setting transmission process is performed, and various commands are transmitted to the first sub-control unit 400. Note that the output schedule information transmitted to the first sub-control unit 400 is composed of 16 bits in the present embodiment, bit 15 is strobe information (indicating that data is set when ON), bit 11 -14 are command types (in this embodiment, basic command, symbol variation start command, symbol variation stop command, winning effect start command, end effect start command, per round number designation command, power recovery command, RAM clear command, special figure. Bits 0 to 10 are constituted by command data (predetermined information corresponding to the command type).

  Specifically, the strobe information is turned on and off in the command transmission process described above. If the command type is a symbol variation start command, the command data includes information indicating the special symbol stop symbol, information indicating the control state (information indicating the setting state of the time reduction flag and the probability variation flag), and the special symbol variation time. In the case of a symbol variation stop command, information indicating a special symbol stop symbol (result of determining a special symbol), information indicating a control state, and the like, a winning effect start command and an end effect start are included.

  In the general command rotation start setting transmission process described above, information representing the special figure stop symbol (special figure determination result), information representing the control state, and information representing the special figure variation time stored in the RAM 308 as command data. The information indicating the number of the first special figure variable game or the second special figure variable game that is on hold is set.

  In the general command rotation stop setting transmission process described above, information indicating the special figure stop symbol (special figure determination result), information indicating the control state, and the like stored in the RAM 308 is set in the command data.

  In the above-described general command winning effect start setting transmission process, the command data includes the effect control information and the control state that are stored in the RAM 308 and are output to the decorative symbol display device 208, various lamps 418, and the speaker 120 during the winning effect period. Information indicating the number of the first special figure variable game or the second special figure variable game that is held is set. The first sub control unit 400 that has received the winning effect start command transmits a winning effect control command to the second sub control unit 500 based on the winning effect start command. The second sub-control unit 500 that has received the winning effect control command causes the decorative symbol display device 208 to display an image for notifying the player that the big hit game is started for a predetermined opening effect period (for example, 3 seconds), The jackpot game starts.

  In the above-described general command end effect start setting transmission process, the command data includes the effect control information and the control state stored in the RAM 308 and output to the decorative symbol display device 208, various lamps 418, and the speaker 120 during the effect standby period. Information indicating the number of the first special figure variable game or the second special figure variable game that is held is set. The first sub control unit 400 that has received the end effect start command transmits an end effect control command to the second sub control unit 500 based on the end effect start command. Receiving the end effect control command, the second sub-control unit 500 causes the decorative symbol display device 208 to display an image for informing the player that the big hit is to be ended for a predetermined end effect period (for example, 3 seconds). finish.

  In the general command big prize opening release transmission process described above, information indicating the number of winning rounds stored in the RAM 308, the current number of rounds, information indicating the control state, etc. is set in the command data. In the above-described general command big prize opening closing setting transmission process, the command data, the current round number stored in the RAM 308, information indicating the control state, the first special figure variation game or the second special figure variation held. Information indicating the number of games is set.

  In step S231, a general command special figure hold increase process is also performed. In this general command special figure hold increase processing, special figure identification information (information showing special figure 1 or special figure 2) stored in the transmission information storage area of the RAM 308 in the command data of the special figure hold increase command, the control state And information on the special figure 1 or the special figure 2 determined in advance.

  Furthermore, in this step S231, general command usual figure hold increase processing is also performed. In this general command usual figure hold increase process, information indicating a control state is set in the command data of the general figure hold increase command. In addition, the main control unit 300 also transmits to the first sub-control unit 400 a general map change start command indicating that the normal map display has started (or is) as a general command-related command. In addition, the main control unit 300 to the first sub control unit 400 start (do) the common figure change stop command indicating that the change display of the normal figure has stopped (do) or the pair of blade members 2321. An electric chew opening start command indicating that, or an electric chew closing command indicating that the pair of blade members 2321 are closed (to do) may be transmitted.

  In the first sub-control unit 400, it is possible to determine the production control according to the change of the game control in the main control unit 300 by the command type included in the received output schedule information, and it is included in the output schedule information. Based on the information of the command data, the contents of effect control can be determined. In addition, the first sub-control unit 400 acquires the number of remaining rounds until all the rounds are completed based on the number of rounds included in the command and the current number of rounds.

  In this command setting transmission process, a command is also transmitted to the payout control unit 600 shown in FIG. The output schedule information and the payout request information output to the payout control unit 600 are composed of 1 byte, strobe information (indicating that data is set when turned on) in bit 7, and power-on information in bit 6. (In the case of ON, it indicates that this is the first command transmission after power-on), the current processing type (0-3) for encryption in bits 4-5, and the encrypted processing in bits 0-3 The number of payout requests is indicated.

  Next, in the main control unit timer interrupt process shown in FIG. 24, an external output signal setting process (step S233) is performed. In this external output signal setting process, the game information stored in the RAM 308 is output to the information input circuit 350 separate from the pachinko machine 100 via the information output circuit 336.

  In step S235, device monitoring processing is performed.

  FIG. 28 is a flowchart showing the flow of device monitoring processing.

  First, in step S235a, information in the internal information register 3101 is acquired. Since step S235a is executed for each timer interrupt, the information in the internal information register 3101 is acquired for each timer interrupt.

  In step S235b, it is determined whether there is an abnormality in the random number generation circuit 318 based on the information acquired in step S235a. Here, the abnormality of the random number generation circuit refers to both abnormality of the frequency monitoring circuit 3182 and abnormality of the random number monitoring circuit 3184. If it is determined that there is an abnormality, the process proceeds to step S235c. If it is not determined that there is an abnormality, the process proceeds to step S235e.

  In step S235c, the random number generation circuit abnormality flag is set to ON. This flag is stored in the RAM 308. More specifically, there are a flag indicating abnormality of the frequency monitoring circuit 3182 and a flag indicating abnormality of the random number monitoring circuit 3184. Hereinafter, these flags may be collectively referred to as a random number generation circuit abnormality flag.

  In subsequent step S235d, preparation for transmission of a random number generation circuit abnormality flag setting command is executed, and the process proceeds to step S235e. The random number generation circuit abnormality flag setting command is a command including information that can identify whether the frequency monitoring circuit 3182 is abnormal or the random number monitoring circuit 3184 is abnormal.

  In step S235e, other device monitoring processing is executed. For example, by reading the signal states of various sensors stored in the signal state storage area in step 205 described above, the presence or absence of a glass frame opening error or the bottom pan full error is monitored, and the glass frame open error or bottom pan full error is monitored. Device information indicating whether or not there is a glass frame open error or a lower pan full error is set in the transmission information to be transmitted to the first sub-control unit 400. Also, the various solenoids 332 shown in FIG. 4 are driven to control the opening / closing of the second special figure starting port 232 and the variable winning port 234, and the normal symbol display device 210, the first symbol is displayed via the driving circuits 324, 326, 330. Display data to be output to the first special figure display device 212, the second special figure display device 214, the various status display units 328, and the like is set in the output port of the I / O 310. Further, the output schedule information set in the payout request number transmission process (step S219) is output to the first sub-control unit 400 via the output port of the I / O 310. When these processes are finished, the device monitoring process in step S235 is finished.

  In the subsequent step S237, it is determined whether or not the low voltage signal is on in order to determine whether or not a power interruption (power interruption) has been detected. Then, when the low voltage signal is off (when the power supply cutoff is not detected), the process proceeds to step S239, and when the low voltage signal is on (when the power supply cutoff is detected), the process proceeds to step S241.

  In step S239, a timer interrupt end process is performed. In this timer interrupt termination process, the value of each register temporarily saved in step S201 is set in each original register, interrupt permission is set, etc., and then the main control unit main process shown in FIG. Return.

  On the other hand, in step S241, a power interruption process for returning to the power interruption state upon power recovery is performed.

  FIG. 29 is a flowchart showing a flow of power interruption processing in the main control unit.

  In this power interruption process, first, the stack pointer is saved as a return data in a predetermined area of the RAM 308 (step S2431), and then the power status stored in the power status storage area provided in the RAM 308 is updated to information indicating suspend. (Step S2432). Subsequently, a checksum is calculated by adding all the 1-byte data stored in a predetermined area (for example, all areas) of the RAM 308 to a 1-byte register whose initial value is 0, and the calculated checksum Is set in the RAM 308 (step S2433). Finally, access to the RAM 308 is set to be prohibited (step S2433), the power interruption process is terminated, and the pachinko machine 100 is eventually disconnected. When the voltage is restored before the voltage is completely reduced, the reset operation (system) is reset by the reset control circuit 314 when the WDT 3141 provided in the reset control circuit 314 shown in FIG. Reset or user reset).

  Next, a process of acquiring the special winning random number and the normal winning random number in the winning acceptance process (step S217) shown in FIG. 24 will be described.

  FIG. 30 is a diagram showing a flow of processing for obtaining a special winning random number and a normal winning random number in the winning acceptance process in step S217.

  In step S217a, it is determined whether or not the random number generation circuit abnormality flag is set to ON. This flag is a flag set in step S235c of FIG. 28. When there is an abnormality in the frequency of the random number update clock, or when the random number updated by the random number update circuit 3183 shown in FIG. 10 is updated normally. If not, the corresponding flag is set to ON. If this flag is set to ON, the winning acceptance process is terminated. If there is no abnormality, the process proceeds to step S217b.

  In step S217b, there is a special signal of FIG. 1 indicating that the first special figure starting port 230 has won, and the number of special figure variable games held is less than a predetermined number (4 in this embodiment). If the result is negative, the process proceeds to step S217f. If the result is positive, the process proceeds to step S217c. In step S217c, the probability variation flag prepared in the RAM 308 is referred to and it is determined whether or not the probability is changing (special figure high probability state). If the probability variation flag is set to OFF, it means that non-probability variation is in progress (special figure low probability state), and step S217d is executed. In step S217d, a random number is acquired from the random number register of channel CH1 of the random number generation circuit 318. In the present embodiment, a similar signal is sent to the CPU separately from the incoming signal that triggers random number latching, and the CPU responds to a signal in a predetermined channel (here, CH1) based on the reception of the signal. Get the latched random number from the random number register. The CPU 304 adds the value of the R register to the obtained random number, and further obtains a value obtained by adding 1 as the special figure 1 winning random number, and proceeds to step S217f. The CPU 304 recognizes the random number generation range set in step S1053a shown in FIG. 23, and performs addition processing based on the random number generation range. That is, when the added value exceeds the maximum value of the random number generation range, the remaining value is added to the minimum value of the random number generation range.

  On the other hand, if the probability variation flag is set to ON, the probability is changing, and step S217e is executed. In this step S217e, a random number is acquired from the random number register of the channel CH2 of the random number generation circuit 318, and as in step S217d, the CPU 304 adds the value of the R register to the acquired random number, and further adds a value obtained by adding 1. 1 is obtained as a winning random number, and the process proceeds to step S217f.

  In step S217f, there is a special signal of FIG. 2 indicating that the second special figure starting port 232 has been won, and the number of special figure variable games held is less than a predetermined number (4 in this embodiment). If the result is negative, the process proceeds to step S217j. If the result is positive, the process proceeds to step S217g. Also in step S217g, as in step S217c, the probability variation flag prepared in the RAM 308 is referred to, and if the probability variation flag is set to OFF (if non-probability variation is in progress), the random number of channel CH1 of the random number generation circuit 318 The random number is acquired from the register, and similarly to step S217d, the CPU 304 adds the value of the R register to the acquired random number, and further obtains a value obtained by adding 1 as a special figure 2 winning random number (step S217h), The process proceeds to step S217j. On the other hand, if the probability variation flag is set to ON (if the probability is changing), the random number is acquired from the random number register of the channel CH2 of the random number generation circuit 318, and similarly to step S217d, the CPU 304 acquires the random number The value of the R register is added to the value, and a value obtained by adding 1 is obtained as the special figure 2 winning random number (step S217i), and the process proceeds to step S217j.

In step S217j, whether there is a general-purpose entrance signal indicating that a win has been made at the general-purpose start opening 228, and whether the number of general-purpose variable games that are on hold is less than a predetermined number (2 in this embodiment). If the answer is negative, the winning acceptance process ends. If the answer is affirmative, the process proceeds to step S217k. In step S217k, the time reduction flag prepared in the RAM 308 is referred to. If the time reduction flag is set to OFF, it is a normal low probability state (non-electric support), and step S217l is executed. In step S217l, a random number is acquired as a normal winning random number from the random number register of channel CH3 of the random number generation circuit 318, and this winning acceptance process ends. On the other hand, if the time reduction flag is set to ON, it is a normal high probability state (during electric support), and step S217m is executed. In step S217m, a random number is acquired as a regular winning random number from the random number register of channel CH4 of the random number generation circuit 318, and the winning acceptance process is completed.
<Processing of First Sub-Control Unit 400>
The process of the first sub control unit 400 will be described with reference to FIG. FIG. 5A is a flowchart of main processing executed by the CPU 404 of the first sub control unit 400.

  First, in step S301 in FIG. 9A, various initial settings are performed. When the power is turned on, the initial setting in step S301 is executed. In this initial setting, initial setting of the I / O port 410 shown in FIG. 4, initialization processing of a storage area in the RAM 408, and the like are performed.

  In step S303, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10, and when the timer variable becomes 10 or more, the process proceeds to step S305.

  In step S305, 0 is substituted into the timer variable.

  In step S307, command processing is performed. The CPU 404 of the first sub control unit 400 determines whether a command has been received from the main control unit 300. In this command processing, power recovery sub-side flag setting processing and the like are performed, and details will be described later.

  In step S309, effect control processing is performed. For example, when there is a new command in S307, processing such as reading the effect data corresponding to this command from the ROM 406 is performed, and when the effect data needs to be updated, the effect data is updated.

  In step S311, when the pressing of the chance button 136 shown in FIG. 1 is detected, the effect data updated in step S309 is changed to effect data corresponding to the pressing of the chance button 136.

  In step S313, if there is a command to the sound source IC 416 in the effect data read in S309, this command is output to the sound source IC 416.

  In step S315, if there is a command to the drive circuit 420 for the various lamps 418 in the effect data read in S309, this command is output to the drive circuit 420.

  In step S317, if there is a command to the drive circuit 422 of the effect movable body 224 in the effect data read out in S309, this command is output to the drive circuit 422.

  In step S319, when there is a control command to be transmitted to the second sub-control unit 500 in the effect data read in S309, the control command is set to be output, and the process returns to S303.

  Next, the command reception interrupt process of the first sub control unit 400 will be described with reference to FIG. FIG. 31B is a flowchart of the command reception interrupt process of the first sub control unit 400. This command reception interrupt process is a process executed when the first sub-control unit 400 detects a strobe signal output from the main control unit 300. In step S331 of the command reception interrupt process, the command output from the main control unit 300 is stored as an unprocessed command in the command storage area provided in the RAM 408, and the command reception interrupt process is terminated.

  Next, the first sub control unit timer interrupt process executed by the CPU 404 of the first sub control unit 400 will be described with reference to FIG. FIG. 31C is a flowchart of the timer interrupt process of the first sub control unit 400. The first sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and the timer interrupt process is performed by using the timer interrupt as a trigger. Execute in the cycle.

  In step S341 of the first sub control unit timer interrupt process, 1 is added to the value of the timer variable storage area of the RAM 408 described in step S303 in the first sub control unit main process shown in FIG. Is stored in the timer variable storage area. Therefore, in step S303, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

In step S343 of the first sub-control unit timer interrupt process, the control command is transmitted to the second sub-control unit 500 set in step S319, the production random number is updated, and the like. finish.
<Processing of Second Sub-Control Unit 500>
The second sub control unit 500 executes control of the decorative symbol display device 208 based on the control command transmitted from the first sub control unit 400. The second sub-control unit 500 is connected to an image control unit that displays an image on the decorative symbol display device 208. This image control unit has a VRAM (video RAM) and a GPU (graphics processing unit). The GPU reads the picture information and the like stored in the ROM of the second sub-control unit 500 based on the signal from the CPU of the second sub-control unit 500, and uses the display area (work area) of the VRAM to display the display image. The generated image is displayed on the decorative symbol display device 208.

  More specifically, the CPU of the second sub control unit 500 first issues an image data transfer instruction. Here, first, the designation of the drawing areas of the display area A and the display area B of the VRAM is swapped. As a result, an image of one frame stored in the display area not designated as the drawing area is displayed on the decorative design display device 208. Next, the CPU sets ROM coordinates (ROM transfer source address), VRAM coordinates (VRAM transfer destination address) and the like in the GPU attribute register based on the position information table and the like, and then images from the ROM to the VRAM. Set an instruction to start data transfer. The GPU transfers the image data from the ROM to the VRAM based on the instruction set in the attribute register. Thereafter, the GPU outputs a transfer end interrupt signal to the CPU.

  Next, it is determined whether or not a transfer end interrupt signal is input from the GPU. If a transfer end interrupt signal is input, parameters are set based on the production scenario configuration table and attribute data. Here, in order to form a display image in the display area A or B of the VRAM based on the image data transferred to the VRAM, the CPU stores information on the image data constituting the display image (VRAM coordinate axes, image size, VRAM coordinates). (Arrangement coordinates, etc.) The GPU sets parameters according to the attribute based on the instruction stored in the attribute register. On the other hand, when the transfer end interrupt signal from the GPU has not been input, it waits for the transfer end interrupt signal to be input.

  Subsequently, a drawing instruction is performed. In this drawing instruction, the CPU instructs the GPU to start drawing an image. The GPU starts drawing an image in the frame buffer in accordance with an instruction from the CPU.

  When a drawing instruction is performed, it is determined whether or not a generation end interrupt signal from the GPU based on the end of image drawing has been input. If the generation end interrupt signal is not input, the generation end interrupt signal is input. When a generation end interrupt signal is input, the scene display counter that is set in a predetermined area of the RAM and counts how many scene images have been generated is incremented (+1) to finish the process. To do.

  Further, the second sub control unit 500 also executes control of the shielding device 246 based on the control command transmitted from the first sub control unit 400.

  Here, based on the content described above, the operation when the voltage supply to the game machine is reduced will be described.

  For example, when the power is turned off due to a power failure or the like in a big hit state, when the game table is returned to the initial state by turning on the power again, the player becomes extremely disadvantageous. In order to prevent such a situation from occurring, a power interruption process (step S241 in FIG. 24) for holding the state of the game machine with the electric power stored in the capacitor is executed. This power interruption process is executed not only when the power is turned off, but also when the supply voltage temporarily decreases due to factors such as static electricity. Hereinafter, an operation when the power is turned off (hereinafter referred to as “power off”) and an operation when the supply voltage is temporarily reduced (hereinafter referred to as “momentary interruption”) will be described with reference to FIG. FIG. 4A is a diagram showing an operation when the power is off, and FIG. 4B is a diagram showing an operation when there is an instantaneous interruption.

  When the power is turned off, the voltage is not supplied (power interruption occurs), but the voltage does not immediately become 0, but the supply voltage gradually drops due to the electric power stored in the capacitor. When the supply voltage is effective up to a predetermined voltage (9 V in this embodiment), a low voltage signal is transmitted from the voltage monitoring circuit 338 to the CPU 304. By receiving this signal, it is determined that a power interruption has occurred in step S237 of the main control unit timer interrupt process, and the power interruption process in step S241 is executed. FIG. 32A shows that the normal process is executed until the supply voltage drops to 9V after the power interruption occurs, and the process at the time of power interruption is started when the supply voltage becomes 9V. Has been. By this power interruption process, data indicating the state of the game machine is stored in the RAM 308. In the present embodiment, a capacitor is provided that can sufficiently secure the time required for the execution of the power interruption process (main control section power interruption time delay). After that, when the process at the time of power interruption is completed, the apparatus is in a standby state. Thereafter, when the supply of power is not resumed, the voltage drops to 0 and the operation of the game machine stops.

  On the other hand, even in the case of a momentary interruption, a low voltage signal is transmitted from the voltage monitoring circuit 338 to the CPU 304, so that the power interruption process is executed, and then the apparatus enters a standby state. FIG. 32B shows that the power interruption process is started due to a temporary voltage drop. Here, even if the voltage recovers to the operating voltage, the standby state continues. If this standby state continues, WDT 3141 of reset control circuit 314 of main control unit 300 is not restarted (step S203 in FIG. 24 is not executed), and WDT 3141 times out. As a result, the reset control circuit 314 outputs a reset signal (either a system reset signal or a user reset signal). After that, when the main control unit main process shown in FIG. 21 is resumed, the return process (step S109 to step S111) including the data write-back process in step S109 is executed based on the data stored in the power interruption process. . FIG. 32B shows that a reset signal due to timeout of WDT 3141 has been transmitted, so that the process shifts from a standby state to a return process (reset process). By this return processing, the state of the gaming table is restored to the state before the processing at the time of power interruption. Here, if the data stored in the power interruption process is defective, it is determined that the state before the power interruption process cannot be restored, and the contents of the RAM 308 are cleared (step S113 in FIG. 21). ).

  Next, the effect of setting a random number generation range by the random number generation circuit 318 of the present embodiment will be described, and then problems will be described.

  As described above, the random number generation circuit 318 included in the gaming machine of the present embodiment can set a random number generation range that is the basis of the lottery result. Using this function, the game state can be easily set.

  First, the case where the random number generation range is 0 to 65535 will be described. For example, when these random numbers correspond to either winning or losing, an attempt is made to design the winning probability to be 1/400 (0.25%). There are 65536 random numbers to be generated, but when 1/400 of 65536 is calculated, it is 163.84, which is not an integer. If 164 random numbers close to this number are made to correspond, the winning probability is not exactly 1/400.

  Here, it is assumed that the random number generation range is set to 0-49999. Similarly to the above case, in order to make the winning probability 1/400 (0.25%), it is only necessary to match 1/400 of the generated random numbers 50000, that is, 125 values. . For example, the winning probability can be reduced to 1/400 by associating a value of 0 to 124 among 50000 random numbers and associating other values of 125 to 49999 with a loss. That is, the random number generation range (for example, 0 to 49999) and the random number range (for example, 0 to 124) corresponding to the winning can be set so that the winning probability is as designed (for example, 1/400).

  As described above, a desired winning probability can be set by appropriately setting the random number generation range. For example, it is possible to exclude the random number generation range corresponding to the jackpot and leave the random number generation range corresponding to the jackpot, or to prevent generation of random numbers corresponding to half of the random number generation range corresponding to the jackpot. It is. In particular, if a random number generation range as described with reference to FIG. 15 can be set, it becomes easier to design a gaming machine than when only the maximum value is set. For this reason, it can be said that setting the random number generation range is useful in the design of a game machine.

  Next, a method for changing the winning probability by changing the random number generation range will be described. For example, it is assumed that the maximum value of the random number generation range is changed from 49999 to 249 from the state in which the values from 0 to 124 are associated with each other in the random number generation range of 0 to 49999. In this case, the value from 0 to 124 corresponds to the win, the value from 125 to 249 corresponds to the loss, and the winning probability is ½. That is, the winning probability can be easily changed by changing only the random number generation range while fixing the value corresponding to the winning or losing. In the above description, in order to make it easier to understand, the example in which the hit range is biased has been described, but the hit range may not be biased.

  As a method for determining whether it is a hit or a loss based on the generated random number, a method that prepares a table that defines these correspondences and uses this table can be considered. However, if the winning probability is to be changed by this method, it is necessary to prepare a table corresponding to the winning probability and execute a process for selectively using these according to the state of the game. In the above-described method, only one table in which values corresponding to winning or losing are determined is required, so that the memory capacity burden can be reduced. As a matter of course, the process of switching the table is unnecessary.

  In this embodiment, a plurality of random number generation channels having different random number generation ranges are prepared, and the winning probability during the game is changed by using these channels properly. However, the random number generation range is appropriately changed for one channel. The winning probability may be changed by using a configuration to do so.

  In this embodiment, random numbers may be processed and used for lottery. In this case, a corresponding table may be prepared in consideration of processing.

  Here, the problem when the random number generation range is changed unintentionally will be described with reference to FIG. The figure shows the problem of the random number generation range.

  For example, it is assumed that the above-described instantaneous interruption occurs due to factors such as static electricity, and then a return process (user reset) is performed. In this case, the internal register of the random number generation circuit 318 is maintained as it is before the return process. However, information in the internal register may be rewritten due to a change in voltage. If the random number generation range is changed unintentionally, the winning probability will change.

  For example, in the non-stochastic fluctuation state, as shown in the upper part of FIG. 33 (a), a random number generation range of 0 to 49999 is set, and 0 to 124 (range indicated by left-down hatching) is hit. Is a random number corresponding to. It is assumed that a factor such as static electricity is generated in this state, and the random number generation range becomes 0 to 250. In this case, since the winning probability is reduced from 1/400 to 1/2, the store side is seriously damaged.

  Further, in the probability variation state, as shown in the upper part of FIG. 33 (b), a random number generation range of 0 to 4999 is set, and among these, 0 to 124 (range indicated by left-downward hatching) is a hit. Assume that the corresponding random number. It is assumed that a factor such as static electricity is generated in this state and the random number generation range becomes 0 to 59999. In this case, the winning probability is reduced from 1/40 to 1/480, which is extremely disadvantageous for the player.

  As explained in the above example, if lottery processing is performed using a method that limits the numerical range in which random numbers are generated to an arbitrary numerical range, the lottery processing will not be performed if the numerical range restricted due to some abnormality changes. There arises a problem that it leads to stabilization.

  In order to prevent such a situation, in the gaming machine of this embodiment, in step S1053a in FIG. 23, a process for resetting the random number generation range to a state immediately before the cause of the return process is executed. By re-setting the random number generation range in this way, the above problem can be prevented from occurring. That is, it is possible to prevent the lottery process from becoming unstable while performing the lottery process using a method of limiting the numerical value range in which the random numbers are generated to an arbitrary numerical value range.

  In this embodiment, since the random number generation range is set when the game machine is started, the state immediately before the cause of the return process is the same as the initial state. For example, the random number generation range is set during the game. In the case of a changeable configuration, a process for returning to the previous state may be executed.

  In addition, as in this embodiment, the random number generation range is reset for a channel for which the random number generation range is set, and the random number generation range is set for a channel for which the random number generation range is not set. In the case of a configuration that is not corrected, there are channels that are initialized and channels that are not initialized. In this case, since it is not known whether the channel is initialized from the outside of the basic circuit 302, there is an effect of preventing fraud.

  Furthermore, in the gaming machine of this embodiment, the random number register 3188 is allowed to be latched in step S1053b of FIG. In this way, when there is an abnormality in the random number latched in the random number register 3188, the frequency with which this random number is used can be lowered. At this time, the content of the random number latch flag register 3189 is rewritten with information indicating that the random number register 3188 is in a state in which the random number can be latched. In this embodiment, the random number register 3188 and the random number generation range are set simultaneously by the user program (see FIG. 22). It may be. In the gaming machine of this embodiment, even if the random number register 3188 enters the permissible state, the random number remains until a new random number is latched, but if possible, the value of the random number register 3188 is set to a predetermined value. You may make it set (for example, set to 0). In this case, it is possible not to use random numbers that may be abnormal.

  The above-described resetting is performed after the user reset by the WDT 3141 is performed and then the drive voltage is determined (step S103 in FIG. 20) (step S1053 in FIG. 21). The time required for this determination processing is the voltage supply condition. Because it depends on, it is not constant. For this reason, it is possible to give randomness to the timing at which random numbers reflecting the resetting start to be output, which is effective in preventing fraud. Note that the same effect can be obtained in the above-described configuration in which the maximum random number is updated when an update command is received from the CPU 304.

  In the above description, an example of a problem caused by a change in voltage and a countermeasure for the problem has been described. However, for example, a value in the start value selection circuit 3183b of the random number generation circuit 318 may be rewritten. is there. In this case, a value that should not be generated may be output from the random number update circuit 3183. Also for such a problem, as in the example of the random number generation range described above, by executing a process of resetting the value in the start value selection circuit 3183b to the state immediately before the cause of the return process occurs, It is possible to prevent the above problems from occurring. In addition, the value in the start value selection circuit 3183b may be reset separately according to the random number generation range. That is, it is possible to prevent an abnormal operation from occurring due to a voltage change by executing a process of appropriately resetting a value that can be set by the random number generation circuit 318 as necessary.

  In addition to the change in voltage, for example, when an unexpected operation occurs due to traveling outside the specified area, the above-described problem may occur. In particular, when traveling outside the designated area, there is a high possibility that the same situation will be reproduced due to a program mistake or the like, and there is a risk that fraud will be easier than when the voltage changes. Therefore, in this embodiment, even when traveling outside the designated area occurs, resetting is performed by step S1053a and step S1053b in FIG.

  Here, based on the above description, a supplementary description will be given of the start timing (step S111, step S115) of WDT 3141 in the main process of the main control unit in FIG.

  In normal WDT, counting up is performed independently of program execution. With this configuration, even if there is some problem in the execution of the program, the reset operation (user reset in the present embodiment) can be executed without being affected by this. For this reason, WDT needs to be activated (reactivated) at the time of initial setting. However, there may be a problem depending on the start timing. This problem will be described by taking as an example a case where WDT is started immediately after the initial setting 1 in step S101 in FIG.

  It is assumed that the main process of the main control unit is started in a state where data for restoration is stored in the RAM 308 by the user reset. First, initial setting 1 is executed in step S101, and then WDT is activated. Next, standby processing in step S103 is executed until a sufficient drive voltage is secured.

  For example, when the above-described user reset is executed due to instability of the supply voltage, the execution time of this standby process may become long. If the standby process takes a long time, the WDT may time out during the subsequent execution of step S107 or step S109, and the user reset may be executed again. In this case, since the main control unit main process is executed again from the beginning, the processing time until the return data stored in the RAM 308 is returned to the register becomes long.

  Further, for example, in step S109, when the process of returning the data of the RAM 308 to the register and erasing the data of the RAM 308 is executed, the user reset is executed in a state where a part of the data of the RAM 308 is erased. There is also a possibility. In this case, even if the main control unit main process is executed again from the beginning, the restoration data in the RAM 308 is incomplete, and it is not determined that restoration is possible in step S107. Even if it is determined in step S107 that recovery is possible, the data write-back processing in step S109 cannot completely return to the state before the user reset.

  In order to avoid such a problem, the present embodiment is configured to start the WDT 3141 after the determination of the drive voltage and before the main control unit timer interrupt process is permitted (steps S111 and S115). ). The above configuration is an example, and WDT 3141 is activated so that WDT 3141 does not time out after main control unit main processing is started after user reset and before main control unit timer interrupt processing is permitted. It is preferable to do. In addition, after the user reset is performed, the main control unit starts the progress of the game (in this embodiment, steps S117 to S119 of the main control unit main process are started, and the main control unit timer interrupt process is started). WDT 3141 is preferably activated so that WDT 3141 does not time out before In particular, the process for returning the game after the user reset (the process for enabling the progress of the game) includes a standby process for executing the initial setting process of the liquid crystal image display device (decorated symbol display device). In such a case, the above problem is more likely to occur, so that the WDT 3141 is activated more effectively at the timing described above. Furthermore, even if the WDT 3141 is activated in the first process of the main control unit timer interrupt process, the above problem can be avoided. In the above description, the case where the user reset is executed is described as an example, but the same applies to the case where the system reset is executed.

  Here, a modified example of the random number update circuit 3183 described with reference to FIG. 12 will be described with reference to FIG. This figure shows a modification of the random number update circuit 3183 described in FIG.

  A random number update circuit 3183n shown in FIG. 34A is obtained by adding a random number sequence change circuit 3183d to the random number update circuit 3183 described in FIG.

  The random number sequence change circuit 3183d is provided with a plurality of random number tables in advance. FIG. 34 (b) shows a plurality of random number sequences in which an array of 65536 random numbers is predetermined. When using these plurality of random number sequences, it is possible to set whether to use the same random number sequence continuously or to change to another random number sequence when one random number sequence is made a round. Furthermore, when changing to another random number sequence, it is possible to set whether to change automatically even if there is no instruction, or whether to instruct a change each time. Note that when a round signal is received from the counter circuit 3183a, it is determined that one round of the random number sequence has been made.

  When the random number sequence to be used in the random number sequence changing circuit 3183d is determined, a value is extracted from this random number sequence according to the count value output from the counter circuit 3183a. This extracted value is output as a random number. For example, in FIG. 34B, when it is decided to use the random number sequence B, when a count value “5” is input, “9806” is output as a random number (the thick frame in FIG. 34B). (See the part indicated by).

  Here, an example of processing when the maximum value is set in the maximum value setting register 3183c will be described.

  In FIG. 14, the example in which the range of values output from the count circuit 3183a is changed according to the maximum value set in the maximum value setting register 3183c has been described. In FIG. 14, the value output from the count circuit 3183a is used as a random number as it is. Here, the value output from the count circuit 3183a is used as a count value instead of a random number, and is input to the random number sequence change circuit 3183d.

  For example, when the maximum value is set to 9999, a count value of 0 to 9999 is output from the count circuit 3183a. Here, the random number sequence change circuit 3183d acquires the maximum value data from the maximum value setting register 3183c, and executes a process of deleting a value exceeding the maximum value from the values of the random number sequence and filling the empty portion. By this process, a random number sequence in which values 0 to 9999 are randomly arranged is prepared. When a value corresponding to the count value is output as a random number using this random number sequence, a random number having a random number generation range of 0 to 9999 can be output. Note that the above method is an example. For example, when a value corresponding to a count value is referred to from a random number sequence and the maximum value is exceeded, subsequent values are sequentially referred to, and the referenced value indicates the maximum value. Other methods may be used, such as outputting a value that does not exceed the value.

  Here, an example of detecting an abnormality in the random number monitoring circuit 3184 when the random number update circuit 3183n is used will be described. In this case, the count value output from the counter circuit 3183a is compared before and after one random number update, and it is checked whether or not the same count value is output. If the same count value is output, information indicating abnormality is output. The check timing may be every predetermined cycle longer than the random number update cycle. The random number monitoring circuit 3184 may monitor the random number output from the random number sequence changing circuit 3183d. However, as described above, the monitoring accuracy is improved by monitoring the count value output from the counter circuit 3138a. At the same time, the monitoring burden can be reduced.

  Further, as described in the random number generation circuit 318 shown in FIG. 10, a random number monitoring circuit 3183n may be provided outside the random number generation circuit 318, and a random number monitoring circuit 3184 is provided inside the random number update circuit 3183n. May be.

<Pattern arrangement>
A plurality of types (eight types in this embodiment) of symbols shown on the right side of the figure are arranged on each reel 110 ′ to 112 ′ by a predetermined number of frames (21 frames of numbers 0 to 20 in this embodiment). Yes. Also, numbers 0 to 20 shown at the left end of the figure are numbers indicating the arrangement positions of symbols on the reels 110 ′ to 112 ′. For example, in this embodiment, the number 1 frame on the left reel 110 ′ has a “replay” symbol, the number 0 frame on the middle reel 111 ′ has a “bell” symbol, and the number 2 frame on the right reel 112 ′. Each has a "watermelon" symbol.

<Type of winning prize>
Next, the types of winning combinations of the slot machine 100 ′ will be described with reference to FIG. This figure shows the types of winning combinations (including actuating combinations), symbol combinations corresponding to each winning combination, and the operation or payout of each winning combination.

  Of the winning combinations in the present embodiment, the big bonuses (BB1, BB2) and the regular bonus (RB) are used as a combination for shifting to the bonus game, and the replay (replay) is a replay without newly inserting a medal. Each winning combination is sometimes distinguished from a winning combination and sometimes called an “acting combination”. However, in the “winning combination” in this embodiment, a big bonus, a regular bonus, and a replay that are operating combinations are included. included. In addition, the “winning” in the present embodiment includes a case where a symbol combination of an actuator not accompanied by a medal payout (without a medal payout) is displayed on the active line, for example, a big bonus, a regular Includes bonuses and replay wins.

  The winning combination of the slot machine 100 'includes a big bonus (BB1, BB2), a regular bonus (RB), a small combination (cherry, watermelon, bell), and replay (replay). Needless to say, the type of winning combination is not limited to this and can be arbitrarily adopted.

  “Big Bonus (BB1, BB2)” (hereinafter sometimes simply referred to as “BB”) is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning a prize. . As for the corresponding symbol combinations, BB1 is “BB1-BB1-BB1” and BB2 is “BB2-BB2-BB2”. Further, flag carryover is performed for BB1 and BB2. That is, when BB1 and BB2 are won internally, a flag indicating this is raised (stored in a predetermined area of the RAM 308 ′ of the main control unit 300 ′), but even if BB1 and BB2 are not won in the game. The flag indicating the internal winning is maintained until winning, the BB1 and BB2 are still in the internal winning even after the next game, and the symbol combination corresponding to BB1 "BB1-BB1-BB1", the symbol combination corresponding to BB2 "BB2-BB2-BB2" is in a state where all the prizes are won.

  The “regular bonus (RB)” is a special combination (operating combination) in which a regular bonus game (RB game) is started by winning. The corresponding symbol combination is “RB-RB-RB”. Note that the RB carries over the flag as well as the above-mentioned BB. However, in the big bonus game (BB game) (details will be described later), the regular bonus game (RB game) is won internally and the combination of symbols is displayed on the winning line. In addition, the regular bonus game is started after the start of the big bonus game, and when the regular bonus game is finished once, the regular bonus game is automatically started so that the next regular bonus game is immediately started. It is good.

  “Short (cherry, watermelon, bell)” (hereinafter, simply referred to as “cherry”, “watermelon”, “bell”) is a winning combination in which a predetermined number of medals are paid out by winning. The symbol combinations are “cherry-ANY-ANY” for cherry, “watermelon-watermelon-watermelon” for watermelon, and “bell-bell-bell” for bell. The corresponding payout number is as shown in FIG. In the case of “cherry-ANY-ANY”, the symbol of the left reel 110 may be “cherry”, and the symbol of the middle reel 111 ′ and the right reel 112 ′ may be any symbol.

  “Replay” is a winning combination (operating combination) in which a game can be performed without inserting a medal (game medium) in the next game by winning, and no medal is paid out. The corresponding symbol combination is “replay-replay-replay” for replay.

<Type of gaming state>
Next, the types of gaming state of the slot machine 100 ′ will be described. The gaming state is information for identifying the type of lottery data selected in a lottery or the like. In the present embodiment, the gaming state of the slot machine 100 ′ is roughly divided into a normal game, a BB game, an RB game, and an internal winning game of a big bonus (BB) and a regular bonus (RB). However, the internal winning game may be a division included in the normal game.

<Normal game>
The winning combinations that are internally won for normal games include a big bonus (BB), regular bonus (RB), replay (replay), and small roles (cherry, watermelon, bell).

  “Big Bonus (BB)” is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning. “Regular Bonus (RB)” is a special combination (operating combination) that starts a regular bonus game (RB game) upon winning. The “replay” (replay) is a winning combination (operating combination) in which a game can be performed without a medal being inserted in the next game by winning, and no medal is paid out. The “small role” is a winning combination in which a predetermined number of medals are paid out by winning. In addition, the internal winning probability of each combination is obtained from the lottery data prepared for the normal game, the numerical data corresponding to the range of the lottery data associated with each combination is the random number range acquired at the time of the internal lottery. It is obtained by a value divided by numerical data (for example, 65535). The lottery data prepared for the normal game is divided into several numerical ranges in advance, and each combination and lose is associated with each numerical range. It is determined whether the random number obtained as a result of executing the internal lottery is a value corresponding to the lottery data corresponding to which combination, and the internal lottery combination is determined. This lottery data is provided with settings 1 to 6 in which the winning probabilities of at least one combination are different, and a game shop clerk can arbitrarily select and set any set value.

  In the normal game, the internal lottery result is almost lost (big bonus (BB), regular bonus (RB), replay (replay) and small role won), or any stop display result A setting is made so that the stop display result of the losing that does not correspond to the symbol combination of the combination is generally derived, and the total number of medals to be acquired is less than the total number of inserted medals. Therefore, it is a gaming state that is disadvantageous for the player. However, when a predetermined condition is satisfied (for example, when a specific symbol combination is displayed), it is a gaming state that may be changed to increase the probability of internal winning of replaying. In this case, Consumption of medals used for games is suppressed, and a predetermined number of medals are paid out by winning a small role, resulting in a gaming state where the total number of medals earned exceeds the total number of medals inserted, which is beneficial to the player May become a gaming state.

<BB game>
The BB game is set to be in a gaming state that is beneficial to the player. That is, the BB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the BB game is started by winning a big bonus (BB), and an RB game (described later) can be continuously executed repeatedly, and a predetermined number (for example, during the game) The process ends when more than 465 medals are obtained. However, the BB game only needs to be able to execute the RB game a plurality of times. For example, when a combination (for example, replay-replay-replay) is set for starting the RB game, and this combination is won internally, or The RB game may be set to start when winning. Furthermore, in the BB game, when the BB general game excluding the RB game during the BB game is executed a predetermined number of times (for example, 30 times), or the number of the RB games executed during the BB game is a predetermined number of times. It may be made to end when it reaches (for example, three times).

<RB game>
The RB game is set so as to be in a gaming state that is beneficial to the player. That is, the RB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the RB game is started by winning a regular bonus (RB), and a predetermined role is set to a variation that increases the probability of internal winning (for example, “setting 1” or “normal game”). The internal winning probability 1/15 of “small role 1” is increased to an internal winning probability 1 / 1.2, which is a predetermined value), and a predetermined number (for example, 8 times) It ends when there is a prize. In the RB game, when a predetermined number of times (at least 2 times) is won (for example, 8 times), or when the number of RB games executed during the RB game reaches a predetermined number of times (for example, (8 times). Since the BB game described above can execute the RB game a plurality of times, when a single RB game is performed, the number of medals less than the total number of medals obtained in the BB game is acquired and terminated. Become.

<Big winning (BB) and regular bonus (RB) internal winning games>
The winning combination that is internally won for the internal winning game of the big bonus (BB) and the regular bonus (RB) includes a replay and a small role. The big bonus (BB) and the regular bonus (RB) are not won internally, and are game states in which a symbol combination corresponding to the big bonus (BB) or the regular bonus (RB) can be won.

  However, the probability of the internal winning of the replay may be changed from the next game that has been internally won to the big bonus (BB) and the regular bonus (RB), for example, the probability of increasing the internal winning probability of the replay is changed. Until the symbol combination corresponding to the big bonus (BB) and regular bonus (RB) wins, the total number of medals to be acquired is almost the same as the total number of inserted medals, and is compared with the normal game. The gaming state may be beneficial to the player. It should be noted that BB game and RB game are both game states that are beneficial to the player, and may be generally referred to as bonus games or special games.

<Main control unit main processing>
Next, main control unit main processing executed by the CPU 304 ′ of the main control unit 300 ′ will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit. This main control unit main process corresponds to the process in the above-described user mode (see FIGS. 8 and 9), and is a process executed regardless of whether a system reset is applied or a user reset is applied.

  As described above, the main control unit 300 ′ is provided with the start signal output circuit (reset signal output circuit) 338 ′ that outputs a start signal (reset signal) when the power is turned on. The CPU 304 ′ of the basic circuit 302 ′ to which the activation signal has been input performs a reset control interrupt start and executes main control unit main processing shown in FIG. 39 in accordance with a control program stored in advance in the ROM 306 ′.

  When the power is turned on, first, various initial setting processes are performed in step S101 '. In this initial setting, a stack initial value is set in the stack pointer (SP) of the CPU 304 ′, an interrupt is disabled, an I / O 310 ′ is initially set, various variables stored in the RAM 308 are initially set, and a reset control circuit 314 is set. The operation permission to the WDT 3141 provided in 'and setting of initial values are performed. This initial setting process will be described later with reference to FIG.

  In step S103 ', medal insertion / start operation acceptance processing is executed. Here, it is checked whether or not a medal has been inserted, and the winning line display lamp 120 'is turned on in response to the insertion of a medal. Note that when a re-win is won in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that it is not necessary for the player to insert medals. Further, it is checked whether or not the start lever 135 'has been operated. If there is an operation of the start lever 135', the process proceeds to step S105 '.

  In step S105 ', the number of inserted medals is determined, and an effective winning line is determined.

  In step S107 ', the random number generated by the random number generation circuit 316' is acquired.

  In step S109 ', the winning combination lottery table stored in the ROM 306' is read according to the current gaming state, and an internal lottery is performed using this and the random number acquired in step S107 '. As a result of the internal lottery, when any winning combination (including an operating combination) is won internally, the flag of the winning combination is turned ON.

  In step S111 ', reel stop data is selected based on the internal lottery result.

  In step S113 ', rotation of all reels 110' to 112 'is started.

  In step S115 ′, the stop buttons 137 ′ to 139 ′ can be received. When any one of the stop buttons is pressed, one of the reels 110 ′ to 112 ′ corresponding to the pressed stop button is selected in step S111 ′. Is stopped based on the reel stop control data selected in. When all the reels 110 'to 112' are stopped, the process proceeds to step S117 '.

  In step S117 ', a winning determination is performed. Here, it is determined that the winning combination is won when a picture combination corresponding to some winning combination is displayed on the activated winning line 114 ′. For example, if “bell-bell-bell” is aligned on the activated winning line, it is determined that the player has won the bell.

  In step S119 ', if any winning combination with a payout has been won, the number of medals corresponding to the winning combination is paid out according to the number of winning lines.

  In step S121 ', game state control processing is performed. In the game state control process, a process related to transition of each game state of normal game, BB game, RB game, and internal winning game is performed, and the game state is shifted when those start conditions and end conditions are satisfied. Thus, one game is completed. Thereafter, returning to step S103 'and repeating the above-described processing, the game proceeds.

<Main control unit 300 'timer interrupt processing>
Next, the main control unit timer interrupt process executed by the CPU 304 ′ of the main control unit 300 ′ will be described with reference to FIG. This figure is a flowchart showing the flow of the main control unit timer interrupt process.

  The main control unit 300 ′ includes a timer circuit 311 ′ that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 2 ms), and the main control unit timer is triggered by this timer interrupt signal. Interrupt processing is started at a predetermined cycle.

  In step S201 ', a timer interrupt start process is performed. In this timer interrupt start process, a process of temporarily saving each register value of the CPU 304 ′ to the stack area is performed.

  In step S203 ′, the count value of the WDT 3141 of the reset control circuit 314 ′ exceeds the initial setting value (32.8 ms in the present embodiment) so that no WDT interrupt occurs (so as not to detect a processing abnormality) The WDT 3141 is periodically restarted (in this embodiment, about once every 2 ms, which is the main control unit timer interrupt period).

  In step S205 ', input port state update processing is performed. In this input port state update process, the detection signals of the sensor circuits 320 ′ of the various sensors 318 ′ are input via the input ports of the I / O 310 ′ to monitor the presence or absence of the detection signals, and the various sensors 318 ′ are stored in the RAM 308 ′. Each signal is stored in a signal state storage area provided separately. Here, the random number is read from the random number register 3188. Hereinafter, this reason will be described.

  In the random number generation circuit 316 ', when the start lever 135' is operated, the random number is latched regardless of whether or not the random number is used. Since this value is held until it is read out, for example, the value latched when the start lever 135 'is operated during the rotation of the reel may be used for the next game lottery. As a result, for example, although the game is newly started, the game progresses according to the already determined lottery result, and there is no room for the player who newly started the game to intervene. Problems arise. For this reason, by reading the value of the random number register 3188 at every timer interruption, a random number can be acquired by operating the start lever 135 at the start of the game. For example, the random number may be acquired by operating the start lever 135 at the start of the game by reading the value of the random number register 3188 when a medal is inserted. Alternatively, a random number may be acquired using a software latch by accepting an operation of the start lever 135 at the start of the game.

  Subsequent to step S205 ', in step S207', various game processes are performed. Specifically, an interrupt status is acquired (various interrupt statuses are acquired based on signals from various sensors 318 ′), and processing according to this status is performed (for example, the acquired stop buttons 137 ′ to 139 ′). Based on the interrupt status, stop button reception processing is performed).

  In step S209 ', timer update processing is performed. Various timers are updated for each time unit.

  In step S211 ', command setting transmission processing is performed, and various commands are transmitted to the first sub-control unit 400'. Note that the output schedule information transmitted to the first sub-control unit 400 ′ is composed of 16 bits in this embodiment, and bit 15 is strobe information (indicating that data is set when ON), bit 11 to 14 are command types (in this embodiment, basic command, start lever reception command, effect command accompanying effect lottery processing, rotation start command accompanying the start of rotation of reels 110 'to 112', stop buttons 137 'to 139 ) Stop button acceptance command associated with acceptance of operation, stop position information command associated with stop processing of reels 110 'to 112', payout number command and payout end command associated with medal payout processing, command indicating gaming state, etc.), bit 0 to 10 are composed of command data (predetermined information corresponding to the command type).

  In the first sub-control unit 400 ′, it is possible to determine the production control according to the change of the game control in the main control unit 300 ′ by the command type included in the received output schedule information, and it is included in the output schedule information. The contents of the effect control can be determined based on the command data information.

  In step S213 ', an external output signal setting process is performed. In this external output signal setting process, game information stored in the RAM 308 'is output to an information input circuit 652' separate from the slot machine 100 'via the information output circuit 334'.

  In step S215 ', device monitoring processing is performed. Here, the same processing as the device monitoring processing in the gaming machine of the first embodiment is performed. Specifically, first, the information in the internal information register 3101 is referred to as described with reference to FIG. 28, and if there is information indicating abnormality, the random number generation circuit abnormality flag (in the above-described error flag) provided in the RAM 308 ′. Type) is set on. When this flag is set to ON, the slot machine 100 ′ executes an error process for stopping the progress of the game by the player's operation at a predetermined timing (for example, a state where a medal insertion can be accepted). (For example, even if an operation for advancing the game is detected in step S205 ′, the corresponding process is not executed). Thereafter, in step S205 ′, the signal states of the various sensors 318 ′ stored in the signal state storage area are read, and the presence / absence of errors relating to the medal insertion abnormality and the medal payout abnormality is monitored. If an error is detected (not shown) ) The error flag is set to ON and error processing is executed. Further, according to the current gaming state, the medal selector 170 '(medal blocker in which the solenoid provided in the medal selector 170' operates), various lamps 338 ', and various 7 segment (SEG) indicators are set.

  Note that the progress of the game is allowed from the state in which the error release switch is operated and the error process is being executed (for example, the corresponding process is executed when an operation to advance the game is detected in step S205 ′). When executing the return process for returning to the state, the information in the internal information register 3101 described above is acquired and the process for discarding the acquired information is executed, so that the random number generation circuit is executed when the return process is executed. Even if 316 ′ is normal, it is possible to prevent the error processing from being executed again.

  In step S217 ', it is monitored whether or not the low voltage signal is on. If the low voltage signal is on (when the power supply is detected to be cut off), the process proceeds to step S221 ′. If the low voltage signal is off (if the power supply is not cut off), the process proceeds to step S219 ′. move on.

  In step S219 ', various processes for ending the timer interrupt end process are performed. In this timer interrupt end process, the value of each register temporarily saved in step S201 'is set in each original register. Thereafter, the process returns to the main control unit main process shown in FIG.

  On the other hand, in step S221 ′, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is saved as a return data in a predetermined area of the RAM 308 ′, and power-off such as initialization of an input / output port is performed. Then, the process returns to the main process of the main control unit shown in FIG.

  Next, details of the initial setting process in step S101 of FIG. 39 will be described with reference to FIG. This figure is a flowchart of the initial setting process in step S101 of FIG.

  First, initial setting 1 is performed in step S1001 'executed first. In this initial setting 1, setting of a stack initial value (temporary setting) to the stack pointer (SP) of the CPU 304 ′, setting of an interrupt mask, initial setting of the I / O 310 ′, and initial setting of various variables stored in the RAM 308 ′. Etc.

  In step S1003 ′, whether or not the low voltage signal is ON, that is, the voltage monitoring circuit 330 ′ has a voltage value of the power source supplied to the main control unit 300 less than a predetermined value (9v in this embodiment). If it is, it is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. Then, when the low voltage signal is on (when the CPU 304 ′ detects that the power supply is cut off), this step S1003 ′ is repeatedly executed, and when the low voltage signal is off (the CPU 304 ′ detects that the power supply is cut off). If not, the process proceeds to step S1005 ′. Even if the predetermined value (9 V) is not yet reached immediately after the power is turned on, step S1003 'is repeatedly executed until the supply voltage becomes equal to or higher than the predetermined value.

  In step S1005 ', initial setting 2 is performed. The details of this process are the same as the contents described with reference to FIG.

  In step S1007 ', it is determined whether or not the setting key switch is on. Here, the setting key switch is a switch for setting a player's advantage (for example, six advantages from 1 to 6) in the slot machine 100 '. If this switch is on, the process proceeds to step S1017 '; otherwise, the process proceeds to step S1009'.

  In step S1009 ', it is determined whether or not the data stored in the RAM 308' is abnormal. The data determined here is data saved in the RAM 308 ′ due to the power-off of the slot machine 100 ′ or the above-described instantaneous interruption (see step S <b> 221 ′ in FIG. 40). That is, it is determined in this step S1009 'whether or not the data is surely saved in the RAM 308'. The details of this process are the same as the contents described in step S107 in FIG. If there is an abnormality in the data, the process proceeds to step S1021 '. If there is no abnormality, the process proceeds to step S1011'.

  In step S1011 ', it is determined whether forced RWM clear is in an ON state. Specifically, when the power is turned on and a RWM clear button (not shown) is pressed long (for example, pressed for 5 seconds or more), the forced RWM clear is turned on. If the forced RWM clear is in the ON state, the process proceeds to step S1019 '. If the forced RWM clear is in the OFF state, the process proceeds to step S1013'.

  In step S1013 ', data stored in the RAM 308' is written back to the register of the CPU 304, and a process of returning the register state to the state immediately before the power interruption process is executed. The details of this process are the same as the contents described in step S109 in FIG. After this process, the process proceeds to step S1015 '.

  In step S1015 ', processing for starting WDT 3141 is performed. Here, activation permission of WDT 3141, setting of an initial value, and the like are performed. In the present embodiment, a numerical value corresponding to 32.8 ms is set as an initial value in WDT 3141. Thereafter, the initial setting process is terminated.

  In step S <b> 1007 ′, in step S <b> 1017 ′ that proceeds when the setting key switch is on, a setting value change process is executed according to the state of the setting key. Thereafter, the process proceeds to step S1019 '.

  In step S1019 ', an RWM clear process is performed. The details of this process are the same as the contents described in step S109 in FIG. After this process, the process proceeds to step S1015 '.

  In step S1021 ', which proceeds when it is determined in step S1009' that the data in the RAM 308 'is abnormal, RWM error processing is performed. In this RWM error processing, after making preparations for clearing the storage areas of all the RAMs (RWM) 308 excluding the used stack area, the process shifts to an infinite loop state. In this state, the game can be started by operating the setting key switch after the power is turned on again.
