Description

  The present invention relates to a gaming machine such as a ball game machine or a revolving game machine.

  Conventionally, pachinko machines are configured to control a special game (big hit) when a winning ball is won at the start opening provided on the game board and when a big hit lottery is won. Has been. In such special games, the big prize opening provided on the game board is opened to facilitate the winning of the game ball, and the prize ball corresponding to the game ball won in the big prize opening is paid out to the player. It is like that.

  In such a gaming machine, a program for performing a lottery lottery process or the like is illegally altered, or a legitimate electronic component (such as a ROM or a one-chip microcomputer on which a ROM is mounted) is changed to an illegal electronic component. There is a rampant act of deliberately paying out game balls by exchanging them.

  For this reason, conventionally, a game for determining the legitimacy of a one-chip microcomputer by adding unique information (ID code) to a one-chip microcomputer (amuse chip) equipped with a CPU, ROM and RAM for controlling the game. A machine is known (see Patent Document 1).

  Specifically, when the gaming machine receives a management information request from the ball lending machine, it outputs the ID code of the one-chip microcomputer to the ball lending machine. The ball lending machine is configured to determine the validity of the one-chip microcomputer of the gaming machine based on the ID code of the one-chip microcomputer acquired from the gaming machine. In addition, when the power is turned on, the checksums of so-called programs are compared, and when the validity is determined, the game control process is repeatedly performed.

JP 2010-57979 A

  Here, in a gaming machine having a so-called backup function, a checksum (inspection value) is generated from the data stored in the RAM when the power is turned off and when the power is turned on. It is widely known that when the checksums match, the state is restored to the power-off state, and when the checksums do not match, the data stored in the RAM as an error is erased.

Then, as described in Patent Document 1, in a gaming machine that outputs information such as unique information, the output data to be output, the timing of the output data, or the output state (transmission counter) are managed while being managed by the RAM. When outputting data sequentially, if the power is cut off while outputting the output data, a checksum is not generated when the power is turned off, or a checksum is not generated based on the latest RAM when the power is turned off. As a result, there is a problem that the checksum is not generated effectively when the power is turned off.
For this reason, when the power is turned on (when the power is restored), the checksums at the time of power-off and at the time of power-on do not match, and the backup function does not operate effectively.

  In particular, when outputting game machine specific information to a ball lending machine, the problem is that the output completion period of the specific information currently takes about 2 seconds, the output completion period is long, and the backup function does not operate effectively. There were more occurrences.

  An object of the present invention is to provide a gaming machine capable of effectively operating a backup function in a gaming machine that outputs information such as unique information.

The first invention is provided with storage means (main RAM 110c) capable of writing and reading information, and capable of storing the written information even when the power is cut off, while reading and writing information about the game in the storage means In a gaming machine that advances the game,

As a result of comparison between the information comparison means (main CPU 110a for comparing the checksums in step S5) and the inspection information comparison means, the first When the inspection information and the second inspection information do not correspond to each other, the information erase unit for erasing the information written in the storage unit (the main CPU 110a for clearing the RAM in step S9) is compared with the inspection information comparison unit. As a result, when the first examination information and the second examination information correspond to each other, a game return means for holding the information written in the storage means and returning the game (the RAM setting process is performed in step S8). Main CPU 110a) to perform, and output related information for outputting specific information (chip external information) for output to a specific device (information management device 200) is generated, and the generated output related information is stored in the storage unit Output-related information generation means (main CPU 110a that performs serial transmission counter update processing in step S65), Based on the output-related information by the force-related information generation means written in said storage means comprises a, a specific information output means (main CPU110a and output circuit 113a) for outputting the identification information to the specific device,
The first inspection information generation unit and the second inspection information generation unit generate the inspection information based on information written in the storage unit, excluding the output related information. .

  The second invention further comprises unique information storage means (first unique number register 116) for storing unique information unique to the gaming machine as the specific information, wherein the specific information output means is stored in the unique information storage means. The stored unique information is output as serial data having a plurality of bit data to the specific device, and the output related information generation means manages the output state for outputting the serial data. Is generated.

The launch member 4c directly connected to the solenoid 4a for rotation rotates. By rotating the launch member 4 c, the game ball 99 stored at the end of the downward slope of the launch rail 42 is launched by the launch member 4 c, and the game ball is launched into the game area 6.

  When the game ball fired as described above rises between the rails 5a and 5b from the launch rail 42 and exceeds the ball return prevention piece 5c, the game ball reaches the game area 6 and then falls in the game area 6. At this time, the game ball falls unpredictably by a plurality of nails and windmills provided in the game area 6.

  The game area 6 is provided with a plurality of general winning awards 12. Each of these general winning ports 12 is provided with a general winning port detecting switch 12a. When the general winning port detecting switch 12a detects a winning of a game ball, a predetermined winning ball (for example, ten game balls) is provided. To be paid out.

  Further, in the area below the center of the game area 6, there are a first start port 14 and a second start port 15 that constitute a start area into which game balls can enter, and a second large area in which game balls can enter. A winning opening 17 is provided.

  The second starting port 15 has a pair of movable pieces 15b, a first mode in which the pair of movable pieces 15b is maintained in a closed state, and a second state in which the pair of movable pieces 15b are in an open state. The movable control is performed. When the second starting port 15 is controlled in the first mode, the winning member of the second large winning port 17 located immediately above the second starting port 15 becomes an obstacle, and the game ball Is impossible to accept. On the other hand, when the second start port 15 is controlled to the second mode, the pair of movable pieces 15b function as a tray, and it is easy to win a game ball to the second start port 15. That is, when the second start port 15 is in the first mode, there is no game ball winning opportunity, and when it is in the second mode, the game ball winning opportunity is increased.

  Here, the first start port 14 is provided with a first start port detection switch 14a for detecting the entrance of a game ball, and the second start port 15 is provided with a second start port detection switch for detecting the entrance of a game ball. 15a is provided.

Also, when the first start port detection switch 14a or the second start port detection switch 15a detects the entry of a game ball, a predetermined prize ball (for example, three game balls) is paid out.

  In addition, the second grand prize winning port 17 is configured by an opening formed in the game board 2. Below the second grand prize opening 17, there is a second big prize opening / closing door 17b that can protrude from the game board surface side to the glass plate 52 side. It is controlled to move between an open state protruding to the side and a closed state buried in the game board surface. When the second grand prize opening opening / closing door 17b protrudes from the game board surface, it functions as a tray for guiding the game ball into the second big prize opening 17, and the game ball can enter the second big prize opening 17. Become. The second big prize opening 17 is provided with a second big prize opening detection switch 17a. When the second big prize opening detection switch 17a detects the entry of a game ball, a predetermined prize ball (for example, 15 game balls) are paid out.

Furthermore, in the area on the right side of the game area 6, there are provided a normal symbol gate 13 constituting a normal area through which game balls can pass and a first grand prize opening 16 through which game balls can enter.
For this reason, if the operation ball 3 is not a game ball which has been greatly rotated and launched with a strong force, the normal design gate 13 and the first big winning opening 16 are configured so that the game ball does not pass or win. Yes. In particular, even if the short game state, which will be described later, is entered, if the game ball flows down to the left side of the game area 6, the game ball will not normally pass through the symbol gate 13, so that it is at the second start port 15. The pair of movable pieces 15b are not opened, and it is difficult for a game ball to win the second starting port 15.

  The normal symbol gate 13 is provided with a gate detection switch 13a for detecting the passage of the game ball. When the gate detection switch 13a detects the passage of the game ball, the normal symbol determination random number value is acquired, which will be described later. “Normal lottery” is performed.

  The first grand prize opening 16 is normally kept closed by the first big prize opening opening / closing door 16b, and it is impossible to enter a game ball. In contrast, when a special game, which will be described later, is started, the first grand prize opening opening / closing door 16b is opened, and the first big prize opening opening / closing door 16b puts the game ball in the first big winning opening 16; It functions as a receiving tray that guides the game ball and can enter the first grand prize opening 16. The first grand prize opening 16 is provided with a first big prize opening detection switch 16a. When the first big prize opening detection switch 16a detects the entry of a game ball, a predetermined prize ball (for example, 15 Game balls).

  Further, in the lowermost area of the game area 6 and the lowermost area of the game area 6, the general winning opening 12, the first starting opening 14, the second starting opening 15, the first major winning opening 16, and the second large winning opening. An out port 11 is provided for discharging game balls that have not entered any of the winning ports 17.

In addition, a decoration member 7 that affects the flow of the game ball is provided in the center of the game area 6. A liquid crystal display device (LCD) 31 is provided at a substantially central portion of the decorative member 7, and an effect driving device 33 in the form of a belt is provided above the liquid crystal display device 31.
In this embodiment, the liquid crystal display device 31 is used as a liquid crystal display. However, a plasma display may be used, a projector, a reel made of an annular structure, a so-called 7-segment LED, a dot matrix, or the like. A display device or the like may be used.

The liquid crystal display device 31 displays an image during standby when no game is being performed, or displays an image according to the progress of the game. Among them, three effect symbols 36 for informing the jackpot lottery result, which will be described later, are displayed, and a combination of specific effect symbols 36 (for example, 777) is stopped and displayed as a jackpot lottery result. A big hit is announced.
More specifically, when a game ball enters the first start port 14 or the second start port 15, the three effect symbols 36 are scroll-displayed, and the scroll is stopped after a predetermined time, The effect design 36 is stopped and displayed. Further, by displaying various images, characters, and the like during the variation display of the effect symbol 36, a high expectation that the player may win a big hit is given to the player.

  The effect driving device 33 gives a player a sense of expectation according to the operation mode. The effect driving device 33 performs, for example, an operation in which the belt moves downward or a rotating member at the center of the belt rotates. Various operational feelings are given to the player depending on the operation mode of the effect driving device 33.

  Furthermore, in addition to the above-described various production devices, the audio output device 32 outputs BGM (background music), SE (sound effects), etc., and produces productions using sound. The illumination direction and the emission color are changed to produce an effect by illumination.

  The effect button 35 is effective only when, for example, a message for operating the effect button 35 is displayed on the liquid crystal display device 31. The effect button 35 is provided with an effect button detection switch 35a. When the effect button detection switch 35a detects the player's operation, a further effect is executed according to this operation.

  In the lower right of the game area 6, a first special symbol display device 20, a second special symbol display device 21, a normal symbol display device 22, a first special symbol hold indicator 23, a second special symbol hold indicator 24, a normal A symbol hold indicator 25 is provided.

  The first special symbol display device 20 is for notifying a lottery result obtained when a game ball enters the first start port 14, and is composed of 7-segment LEDs. That is, a plurality of special symbols corresponding to the jackpot lottery result are provided, and the lottery result is notified to the player by displaying the special symbol corresponding to the jackpot lottery result on the first special symbol display device 20. I am doing so. For example, “7” is displayed when the jackpot is won, and “−” is displayed when the player wins. “7” and “−” displayed in this way are special symbols, but these special symbols are not displayed immediately, but are displayed in a stopped state after being displayed for a predetermined time. .

  Here, the “successful lottery” means that when a game ball enters the first starting port 14 or the second starting port 15, a special symbol determining random number value is acquired, and the acquired special symbol determining random value is acquired. Is a random number value corresponding to “big hit” or a random number value corresponding to “small hit”. The jackpot lottery result is not immediately notified to the player, and the first special symbol display device 20 displays a variation such as blinking of the special symbol, and when the predetermined variation time has passed, the jackpot lottery result The special symbol corresponding to is stopped and displayed so that the player is notified of the lottery result. The second special symbol display device 21 is for notifying a lottery result of a jackpot that is performed when a game ball enters the second start port 15, and the display mode is the above-described first display mode. This is the same as the special symbol display mode in the special symbol display device 20.

  Further, in this embodiment, “big hit” means that a right to win a big hit game is obtained in a big win lottery performed on condition that a game ball has entered the first start port 14 or the second start port 15 Say what you did. In the “hit game”, a round game in which the first big prize opening 16 or the second big prize opening 17 is opened is performed 15 times in total. A predetermined time is set for the maximum opening time of the first grand prize port 16 or the second grand prize port 17 in each round game, and during this time, the first grand prize port 16 or the second grand prize port 17 is set. When a predetermined number of game balls (for example, nine) enter, one round game is completed. In other words, the “big hit game” is a game in which a game ball can enter the first grand prize winning opening 16 or the second big winning prize opening 17 and the player can acquire a winning ball according to the winning prize.

  The normal symbol display device 22 is for notifying the lottery result of the normal symbol that is performed when the game ball passes through the normal symbol gate 13. As will be described in detail later, when the winning symbol is won by the normal symbol lottery, the normal symbol display device 22 is turned on, and then the second start port 15 is controlled to the second mode for a predetermined time.

  Here, “normal symbol lottery” means that when a game ball passes through the normal symbol gate 13, the normal symbol determination random number value is acquired, and the acquired normal symbol determination random value corresponds to “winning”. This is a process for determining whether or not a random value. The lottery result of the normal symbol is not always notified immediately after the game ball passes through the normal symbol gate 13, but the normal symbol display device 22 displays a variation such as blinking of the normal symbol. When the fluctuation time elapses, the normal symbol corresponding to the lottery result of the normal symbol is stopped and displayed so that the player is notified of the lottery result.

Furthermore, if a game ball enters the first start port 14 or the second start port 15 during special symbol fluctuation display or a special game to be described later, and if a big win lottery cannot be performed immediately, a certain condition The right to win a jackpot will be withheld. More specifically, the random number value for special symbol determination acquired when the game ball enters the first start port 14 is stored as the first hold, and when the game ball enters the second start port 15 The acquired special symbol determination random number value is stored as the second hold.
For both of these holds, the upper limit hold number is set to 4, and the hold number is displayed on the first special symbol hold indicator 23 and the second special symbol hold indicator 24, respectively. When there is one first hold, the LED on the left side of the first special symbol hold indicator 23 lights up, and when there are two first holds, two LEDs on the first special symbol hold indicator 23 Lights up. In addition, when there are three first holds, the LED on the left side of the first special symbol hold indicator 23 blinks and the right LED is lit, and when there are four first holds, the first special symbol hold. Two LEDs on the display 23 blink. The second special symbol hold indicator 24 also displays the number of second hold on hold in the same manner as described above.
The upper limit reserved number of normal symbols is also set to four, and the reserved number of normal symbols is displayed in the same manner as the first special symbol hold indicator 23 and the second special symbol hold indicator 24. Displayed on the instrument 25.

(One-chip microcomputer configuration)
Next, the configuration of the one-chip microcomputer 110m and the like provided on the main control board 110 will be described using the block diagram of the main control board 110 in FIG.

  The one-chip microcomputer 110m includes an input port 111, output ports 112a to 112c, a first unique number register 116, a random number generation unit 117, and a hardware ID output unit 119 in addition to the main CPU 110a, the main ROM 110b, and the main RAM 110c. Yes.

The main control board 110 on which the one-chip microcomputer 110m is mounted includes at least output circuits 113a and 113b and connection terminals 118a to 118e. The main control board 110 is provided with various electronic elements in addition to the output circuit and the connection terminals, but illustration thereof is omitted.
Since the main CPU 110a, the main ROM 110b, and the main RAM 110c have been described above, other configurations will be described.

The input port 111 of the one-chip microcomputer 110m inputs a signal from the first connection terminal 118a.
Here, the first connection terminal 118a includes the general winning opening detecting switch 12a, the gate detecting switch 13a, the first starting opening detecting switch 14a, the second starting opening detecting switch 15a, the first large winning opening detecting switch 16a, and the second. It is connected to the big prize opening detection switch 17a. Therefore, various signals from various devices are input to the one-chip microcomputer 110m through the input port 111.

  Note that the connection terminals 118a to 118e in the embodiment do not indicate a one-pin connector, but are described by grouping a plurality of pins distinguished according to signal types.

The first output port 112a outputs a signal to the second connection terminal 118b.
Here, the second connection terminal 118b includes the start port opening / closing solenoid 15c, the first large winning port opening / closing solenoid 16c, the second large winning port opening / closing solenoid 17c, the first special symbol display device 20, and the second special symbol display device 21. The normal symbol display device 22, the first special symbol hold indicator 23, the second special symbol hold indicator 24, and the normal symbol hold indicator 25 are connected. Therefore, various signals from the one-chip microcomputer 110m are output to various devices by the first output port 112a.

  The second output port 112b of the one-chip microcomputer 110m outputs external information serial data, an enable signal, a clock signal, and a latch signal (hereinafter referred to as “external information related signal” as appropriate) to the output circuit 113a.

Here, “external information serial data” is composed of 8-bit serial data, and each bit indicates the content of the information.
For example, the 0th bit of the external information serial data means ON / OFF of the symbol determination signal, the 1st bit of the external information serial data means ON / OFF of 1 signal of jackpot, and 2 of the external information serial data The bit means ON / OFF of two jackpot signals, and the third bit of external information serial data means serial data of chip external information (see FIG. 20B). The “serial data of the chip external information” will be described in detail with reference to FIG.

Then, the output circuit 113a of the main control board 110 inputs an external information related signal from the second output port 112b, and outputs a signal corresponding to each information of the external information serial data based on the input external information related signal. 3 to the connection terminal 118c.
Specifically, the output circuit 113b receives external information serial data triggered by the input of the input enable signal, clock signal, and latch signal, analyzes the number of bits of the external information serial data, and analyzes A signal corresponding to each bit number information is output to each pin of the third connection terminal 118c. For example, if the first bit of the external information serial data is “1 (ON)”, a signal is output to the first pin of the third connection terminal 118c, and the second bit of the external information serial data is “1 (ON)”. ", A signal is output to the second pin of the third connection terminal 118c.

The third connection terminal 118c is connected to a game information output terminal plate 30 that outputs external information (symbol confirmation signal, jackpot signal, chip external information).
Therefore, external information is output to the game information output terminal board 30 by the second output port 112b and the output circuit 113a. The game information output terminal board 30 can be connected to the information management device 200 and can also be connected to a hall facility device (not shown) of the game store. External information can be entered.

  Further, the third output port 112c of the one-chip microcomputer 110m outputs an effect control command to the output circuit 113b.

Then, the output circuit 113b of the main control board 110 inputs an effect control command from the third output port 112c, and outputs the input effect control command to the fourth connection terminal 118d.
Here, the fourth connection terminal 118d is connected to the effect control board 120. Therefore, the effect control command from the one-chip microcomputer 110m is output to the effect control board 120 by the third output port 112c and the output circuit 113b.

The first unique number register 116 is unique information data given at the time of manufacturing the one-chip microcomputer 110m, and is a register that stores a 4-byte first unique number that is different for each one-chip microcomputer 110m.
The first unique number register 116 is connected to the main CPU 110a via the internal bus of the one-chip microcomputer 110m. That is, the first unique number can be said to be a unique number of the one-chip microcomputer 110m that can be read from the user program.

  The random number generation unit 117 is a circuit that randomly generates a random value of 0 to 65535 (16 bits). The random number generation unit 117 is configured so that the random number values of 0 to 65535 are randomly updated in a cycle of 1 minute.

The hardware ID output unit 119 is a circuit for connecting an inspection device (not shown) to the fifth connection terminal 118e of the main control board 110 to determine the validity of the one-chip microcomputer 110m.
Here, the fifth connection terminal 118e on the main control board 110 to which the inspection device is connected and the input / output port 119c on the one-chip microcomputer 110m (hardware ID output unit 119) are the internal parts on the main control board 110. Connected via bus. Therefore, data is exchanged between the inspection device and the hardware ID output unit 119 via the input / output port 119c and the fifth connection terminal 118e.
The hardware ID output unit 119 includes a second unique number storage unit 119a and a collation circuit 119b.

The second unique number storage unit 119a is unique information data attached at the time of manufacturing the one-chip microcomputer 110m, and is a storage unit that stores a second unique number of 8 bytes that is different for each one-chip microcomputer 110m. Here, the first unique number and the second unique number are different numbers.
Unlike the first unique number register 116, the second unique number storage unit 119a is not connected to the main CPU 110a. That is, unlike the first unique number, the second unique number can be said to be a unique number of the one-chip microcomputer 110m that cannot be read from the user program.

When the verification circuit 119b inputs a read signal from an inspection device (not shown) via the input / output port 119c and the fifth connection terminal 118e, the verification circuit 119b inputs the second unique number.
Then, the inputted second unique number and the second unique number stored in the second unique number storage unit 119a are compared, and if they match, it is determined that the one-chip microcomputer 110m is valid, If they do not match, it is determined that the one-chip microcomputer 110m is illegal.
As a result, if it is determined that it is a legitimate one-chip microcomputer 110m, a legitimate signal is output to the inspection device, and if it is determined that it is an illegal one-chip microcomputer 110m, an illegal signal is output to the inspection device. .
Note that the second unique number output from the inspection device (not shown) to the verification circuit 119b is encrypted, and after combining the second unique number encrypted by the verification circuit 119b, the one-chip microcomputer 110m It is desirable to determine the legitimacy of

  Thus, the first unique number for determining fraud on the so-called software and the second unique number for judging fraud on the so-called hardware are different from the first unique number. Therefore, in order to create an illegal one-chip microcomputer 110m, not only the program ROM is altered, but also the main control board must be altered, and both software and hardware must be altered. Therefore, it is possible to make it more difficult to create a counterfeited one-chip microcomputer 110m and to further prevent illegal acts.

Further, in addition to the information management apparatus 200 being able to determine the validity of the one-chip microcomputer 110m based on the first unique number, the validity of the one-chip microcomputer 110m is also judged based on the second unique number even if an inspection device is used. be able to.
As a result, when the fraud determination information from the first unique information is notified, the validity of the one-chip microcomputer 110m can be confirmed again with reference to the second unique information. Can be prevented.

(Configuration of external information for chip output to information management device)
Next, the configuration of the chip external information output to the information management apparatus 200 will be described with reference to FIG. FIG. 7A is a diagram showing a configuration of serial data of chip external information, FIG. 7B is a diagram showing an output configuration of chip external information, and FIG. It is a figure which shows the communication specification of external information for business.

  As shown in FIG. 7A, the chip external information to be output to the information management device 200 includes a 3-byte “maker name” indicating the name of the manufacturer of the gaming machine 1 and a 32-byte name indicating the model name of the gaming machine 1. The “model name” and the 4-byte “first unique number” that is the unique number of the one-chip microcomputer 110m mounted in the gaming machine 1 are configured in this order. That is, in this embodiment, the chip external information is composed of 39 bytes of serial data of the chip external information, and is transmitted in the order of “maker name”, “model name”, and “first unique number” from the first byte. Will be.

The 32-byte “model name” and the 3-byte “maker name” are ASCII data having a 3-byte structure, and the information management apparatus 200 having input the “model name” and the “maker name” has a predetermined value. The “model name” and “manufacturer name” can be directly displayed on the display device.
Also, the information of “model name” and “maker name” is stored in advance in a predetermined storage area of the main ROM 110b, unlike the information of “first unique number”.

As shown in FIG. 7B, the second output port 112b adds a start bit immediately before the first bit (BIT0) of the 1-byte chip external information and adds the last bit of the 1-byte chip external information. A parity bit for error determination is added immediately after (BIT7), a stop bit is added at the end, and external information for chips is sequentially output. Therefore, the chip external information output to the information management apparatus 200 is output by asynchronous serial communication.
Further, when outputting 1-byte chip external information, 3 bits of a start bit, a parity bit, and a stop bit are added, and a total of 11 bits of information are output.

  In the present invention, a unit of information amount in which 3 bits of a start bit, a parity bit, and a stop bit are added to 1-byte external information for a chip is referred to as “one frame”. That is, the 39-byte chip external information can be said to be 39-frame chip external information.

A communication specification of serial data of external information for a chip output from the one-chip microcomputer 110m will be described with reference to FIG.
The baud rate (communication speed) of serial data of the chip external information is set to a low baud rate of 200 bps. Therefore, the 1-bit output completion time is 5 ms. Then, the output completion time for one frame is 55 ms (= 5 ms × 11 bits), and the output completion time for one chip external information (39 frames) is 2145 ms (= 55 ms × 39 frames). That is, the output completion time of the chip external information takes about 2 seconds.

Here, the reason why the baud rate of the serial data of the chip external information is set to a slow baud rate of 200 bps is as follows.
The game information output terminal plate 30 has a transmission element for inputting serial data of chip external information output from the gaming machine 1 to the information management apparatus 200 while the information management apparatus 200 and the gaming machine 1 are insulated. 30a (a photo coupler, a relay, a photo moss, etc.) is provided. For this reason, the communication speed of data between the information management device 200 and the gaming machine 1 must be determined in consideration of the specification of the transfer element 30a (minimum time for data ON and OFF), and depends on the specification of the transfer element 30a. Therefore, the data communication speed between the information management device 200 and the gaming machine 1 must be reduced.
For this reason, in order to eliminate data loss at the transfer element 30a and to cope with various product changes of the transfer element 30a (in order to increase versatility), the communication speed (baud rate) is an extremely low communication speed of 200 bps. Is set.

  Next, details of various tables stored in the main ROM 110b will be described with reference to FIGS.

(Big hit judgment table)
FIG. 8A-1 and FIG. 8A-2 are diagrams showing a jackpot determination table used for the “hit lottery”. FIG. 8A-1 is a jackpot determination table referred to in the first special symbol display device 20, and FIG. 8A-2 is a jackpot determination table referred to in the second special symbol display device 21. is there. In the table of FIG. 8A-1 and FIG. 8A-2, although the winning probability of the small hit is different, the jackpot probability is the same.

Specifically, the big hit determination table is used to determine whether “big hit”, “small hit”, or “losing” based on the current probability gaming state and the acquired random number for determining a special symbol.
For example, according to the jackpot determination table for the first special symbol display device shown in FIG. 8 (a-1), in the low probability gaming state, two special symbol determination disturbances “7” and “8”. The number is determined to be a big hit. On the other hand, in the high probability gaming state, 20 special symbol determination random numbers “7” to “26” are determined to be big hits.
Further, according to the jackpot determination table for the first special symbol display device shown in FIG. 8 (a-1), the random number value for the special symbol determination is obtained in the low probability gaming state or the high probability gaming state. In the case of four special symbol determination random numbers “50”, “100”, “150”, and “200”, it is determined as “small hit”. If the random number is other than the above, it is determined as “lost”.
Therefore, since the random number range of the special symbol determination random number value is 0 to 598, the probability of being determined to be a big hit in the low probability gaming state is 1 / 299.5, and in the high probability gaming state, the big hit The probability to be determined is 10 times up to 1 / 29.9. In the first special symbol display device, the probability of being determined to be a small hit is 1159.75 regardless of whether the game state is a low probability game state or a high probability game state.

(Winning judgment table)
FIG. 8B is a diagram showing a hit determination table used for “ordinary symbol lottery”.
Specifically, the winning determination table determines whether it is “winning” or “lost” based on the presence / absence of the short-time gaming state and the acquired random number for normal symbol determination.
For example, according to the hit determination table shown in FIG. 8B, it is determined that one specific normal symbol random number for determination “0” is a win when in the non-time-saving gaming state. On the other hand, when in the short-time gaming state, it is determined that 65535 specific random symbols for determining normal symbols from “0” to “65534” are hit. If the random number is other than the above, it is determined as “lost”.
Accordingly, since the random number range of the normal symbol determination random number value is 0 to 65535, the probability of being determined to be hit in the non-short-time gaming state is 1/65536, and the probability of being determined to be winning in the time-short gaming state is 65535/65536 = 1 / 1.00002.

(Design determination table)
FIG. 9 is a diagram showing a symbol determination table for determining a special symbol stop symbol.
FIG. 9A is a symbol determination table that is referred to in order to determine a stop symbol at the time of a big hit, and FIG. 9B is a symbol that is referred to in order to determine a stop symbol at the time of a big hit. FIG. 9C is a symbol determination table that is referred to in order to determine the symbol to be stopped when lost.

Specifically, according to the symbol determination table shown in FIG. 9, the type of special symbol display device (the type of the start opening in which the game ball has won) and the game ball at the first start port 14 or the second start port 15 The special symbol type (stop symbol data) is determined based on the jackpot symbol random number value or the small bonus symbol random number value acquired when the ball is entered.
For example, the first special symbol display device refers to the symbol determination table shown in FIG. 9A in the case of a jackpot, and if the acquired jackpot symbol random value is “55”, the stop symbol data is “03”. ”(Special symbol 3 (first positive variation jackpot 3)) is determined. Further, in the first special symbol display device, the symbol determination table shown in FIG. 9B is referred to at the time of small hitting, and if the acquired random number value for small hitting symbol is “50”, as the stopped symbol data “08” (special symbol B (small hit B)) is determined. In case of loss, “00” (special symbol 0 (lost)) is determined as stop symbol data without referring to any random number value.

  Then, at the time of starting the change of the special symbol, an effect designating command is generated as special symbol information based on the determined special symbol type (stop symbol data). Here, the effect designating command is composed of 2-byte data, and 1-byte MODE data for identifying the control command classification and 1-byte DATA indicating the contents of the control command to be executed. It consists of data. The same applies to a variation pattern designation command described later.

  As will be described later, since the game state after the jackpot game and the type of jackpot game are determined by the type of special symbol (stop symbol data), the type of special symbol is the game state after the jackpot game ends. It can be said that the type of jackpot game is determined.

(Description of gaming state)
Next, the gaming state when the game progresses will be described. In this embodiment, there are “low probability gaming state” and “high probability gaming state” as the states related to the jackpot lottery, and “non-short-time gaming state” is the state relating to the pair of movable pieces 15b that the second starting port 15 has. And “short-time gaming state”. The state relating to the jackpot lottery (low probability gaming state, high probability gaming state) and the state relating to the pair of movable pieces 15b (non-short-time gaming state, short-time gaming state) can be associated with each other and are independent. You can also. In other words,
(1) “Low probability gaming state” and “Time saving gaming state”
(2) “Low probability gaming state” and “non-temporary gaming state”
(3) “High probability gaming state” and “short time gaming state”
(4) It is possible to provide a “high probability gaming state” and a “non-temporary gaming state”.
Note that the gaming state when the game is started, that is, the initial gaming state of the gaming machine 1 is a “low probability gaming state” and is set to a “non-short-time gaming state”. Is referred to as a “normal gaming state”.

In the present embodiment, the “low probability gaming state” means that in the jackpot lottery performed on the condition that a game ball has entered the first starting port 14 or the second starting port 15, the winning probability of the jackpot is 1 / The game state set to 299.5. On the other hand, the “high probability gaming state” means a gaming state in which the jackpot winning probability is set to 1 / 29.95. Therefore, in the “high probability gaming state”, it is easier to win a jackpot than in the “low probability gaming state”. Note that a high-probability game flag, which will be described later, is set in this high-probability game state, and the high-probability game flag is off in the low-probability game state.
Further, the low probability gaming state is changed to the high probability gaming state after the jackpot game described later is finished.

  In the present embodiment, the “non-short game state” means that, in the normal symbol lottery performed on the condition that the game ball has passed through the normal symbol gate 13, the variation time of the normal symbol corresponding to the lottery result is 29 seconds. And a game state in which the opening control time of the second start port 15 is set to be as short as 0.2 seconds. That is, when the game ball passes through the normal symbol gate 13, the normal symbol is drawn, and the normal symbol display device 22 displays the fluctuation of the normal symbol, but the normal symbol is displayed 29 seconds after the fluctuation display is started. Stop display later. If the lottery result is a win, the second start port 15 is controlled to the second mode for about 0.2 seconds after the normal symbol stop display.

On the other hand, the “short-time gaming state” means that the normal symbol variation time corresponding to the lottery result is 3 seconds in the normal symbol lottery performed on condition that the game ball has passed through the normal symbol gate 13. , A game that is set shorter than the “non-short game state”, and the opening control time of the second start port 15 when winning in the win is 3.5 seconds, which is set longer than the “non-short game state” State. Further, in the “non-short game state”, the probability of winning in the normal symbol lottery is set to 1/65536, and in the “short time game state”, the probability of winning in the normal symbol lottery is set to 65535/65536. Is set. At this time, the short-time game flag, which will be described later, is set in the short-time game state, and the short-time game flag is off in the non-short-time game state.
Therefore, in the “short-time gaming state”, the second starting port 15 is more easily controlled to the second mode as long as the game ball passes through the normal symbol gate 13 than in the “non-short-time gaming state”. Thereby, in the “short-time gaming state”, the player can advance the game without consuming the game ball.
In addition, since the normal symbol gate 13 is provided in the area on the right side of the game area 6, when in the “short-time game state”, the operation handle 3 is greatly rotated, and the game ball is launched with a strong launch strength. Is configured to do.
Note that the probability of winning in the normal symbol lottery may be set so that it does not change in any of the “non-short-time gaming state” and the “time-short gaming state”.

  Next, the progress of the game in the gaming machine 1 will be described using a flowchart.

(Main processing of main control board)
The main process of the main control board 110 will be described with reference to FIG.

  When power is supplied from the power supply board 170, a system reset occurs in the main CPU 110a, and the main CPU 110a performs the following main processing.

In step S1, the main CPU 110a performs a process of waiting for 2000 ms after the security check of the main CPU 110a.
As described above, the reason for waiting for 2 seconds or more is to wait until the rise time (1.5 seconds) from the power-on of the liquid crystal display device 31.

  In step S2, the main CPU 110a performs initialization processing such as protection control of the main RAM 110c, serial communication port initialization, hard random number activation, watchdog timer initialization, and emission signal setting.

  In step S3, the main CPU 110a determines whether or not the RAM erase switch provided on the back of the gaming machine 1 (not shown) is turned on. If the RAM erase switch is determined to be turned on, the main CPU 110a clears the data in the main RAM 110c. The process moves to step S9. On the other hand, if the RAM erase switch is not determined to be on, the process proceeds to step S4.

In step S4, the main CPU 110a creates a checksum of the main RAM 110c when the power is turned on.
Here, in generating the checksum, as shown in FIG. 12, the checksum is not generated based on the data stored in all the use areas of the main RAM 110c, but is related to the external information for the chip. A checksum is generated excluding data.
Specifically, a checksum is generated based on data stored in a use area of the main RAM 110c excluding chip information enable data, chip information serial transmission counter 1, and chip information serial transmission counter 2 described later. The same applies to the case where a checksum is generated in step S41 described later.

  In step S5, the main CPU 110a compares the checksum of the main RAM 110c generated when the power is turned on with the checksum of the main RAM 110c generated when the power is turned off. If they match, it is determined to be normal, and the process proceeds to step S6. If they do not match, it is determined to be an error, and the process proceeds to step S9.

  In step S6, the main CPU 110a sets a power recovery preparation command indicating that the backup function has been activated effectively and power supply recovery preparation is being performed in the effect transmission data storage area of the main RAM 110c, and issues a power recovery preparation command. Output to the production control board 120.

In step S7, the main CPU 110a performs chip external information output processing in order to output chip external information.
The chip external information output processing will be described in detail with reference to FIG.

  In step S8, the main CPU 110a sets an initial value in the work area of the main RAM 110c that requires an initial value at the time of power failure and power recovery, and performs a RAM setting process when backup is valid.

  In step S9, the main CPU 110a clears the use area of the main RAM 110c in order to clear the state when the power is shut off.

  In step S10, the main CPU 110a sets a RAM clear acceptance designation command indicating that the backup function is not activated and data in the main RAM 110c is cleared in the effect transmission data storage area of the main RAM 110c, and the RAM clear acceptance designation command. Is output to the effect control board 120.

  Here, the presentation control board 120 that has received the “power recovery preparation command” and the “RAM clear acceptance designation command” can perform a predetermined notification to the liquid crystal display device 31 and the like, so that the one-chip microcomputer 110m (main CPU 110a) It is possible to quickly determine that it is activated. In particular, since the information is differentiated between the “power recovery preparation command” and the “RAM clear acceptance designation command”, the power is turned on to the gaming machine 1 and the backup function is activated effectively, or the backup function is activated effectively. Even if it is not, it can be quickly determined.

  In step S11, the main CPU 110a performs chip external information output processing in order to output chip external information, as in step S7. This chip external information output processing will also be described in detail with reference to FIG.

  In step S12, the main CPU 110a sets an initial value in a work area of the main RAM 110c that requires an initial value at the time of initialization, and performs setting processing of the main RAM 110c when backup is not valid.

  In step S13, the main CPU 110a performs initial setting of devices around the CPU. Specifically, an interrupt (CTC) to be used is set, and an initial setting for setting an interrupt timer (4 ms) of a CTC (Counter Timer Circuit) to be used is performed.

  In step S20, the main CPU 110a performs an effect random number update process for updating the reach determination random value and the special figure variation random value for determining the variation mode (variation time) of the special symbol.

  In step S30, the main CPU 110a updates the initial random number value for special symbol determination, the initial random number value for big hit symbol, the initial random number value for small bonus symbol, and the initial random number value for normal symbol determination.

  In step S31, the main CPU 110a determines whether or not the power cutoff flag is ON. If it is determined that the power cut-off flag is ON, the process proceeds to step S40 to prepare for power interruption, and if it is determined that the power cut-off flag is not ON, the process returns to step S20.

  Here, when the power supply board 170 detects a power failure (voltage drop), the power supply board 170 outputs a power interruption detection signal to the main control board 110. Then, the main CPU 110a that has input the power interruption detection signal sets the power interruption flag to ON. Thus, the “power cutoff flag” is turned ON when the power supply board 170 detects a power failure (voltage drop).

Then, unless the power is cut off, in normal games, the processes of Step S20 and Step S30 are repeated until a predetermined interrupt process is performed.
Such a process of repeatedly performing the processes of step S20 and step S30 corresponds to a normal game loop process.

  In step S40, the main CPU 110a saves various data used in the main RAM 110c.

  In step S41, the main CPU 110a creates a checksum of the main RAM 110c when the power is shut off. Here, as in step S4, as shown in FIG. 12, a checksum is generated except for data related to the chip external information.

  In step S42, the main CPU 110a prohibits access to the main RAM 110c and protects the contents of the main RAM 110c. Then, an infinite loop is performed to prepare for power down.

Here, as shown in FIG. 12, the reason for generating the checksum except for the data related to the chip external information is to generate the checksum including the data related to the chip external information. When the power supply is cut off during the output of the chip external information, the checksum at the time of the power cut-off is not generated (steps S66 to S67), a checksum error occurs during the power restoration, and the backup function Because it will not work effectively.
In particular, as described in FIG. 7C, the output time of the chip external information takes 2145 ms (about 2 seconds), the output completion period is long, and the backup function does not operate effectively. It was because I was doing.
According to the present embodiment, since the checksum is generated excluding data related to the chip external information, the backup function can be effectively operated.

(External information output processing for main control board chip)
The chip external information output processing of the main control board 110 will be described with reference to FIG.

  In step S50, the main CPU 110a performs serial transmission data initialization processing for initializing the chip information enable data, chip information serial transmission counter 1, and chip information serial transmission counter 2 stored in the main RAM 110c.

Here, “chip information enable data” is data for outputting enable data indicating that the output of the chip external information is valid.
"Chip information serial transmission counter 1" and "Chip information serial transmission counter 2" are data indicating the output state of serial data (39 bytes) of external information for chips. "Chip information serial transmission counter 1" is 1 The number of bits in a byte is indicated, and “chip information serial transmission counter 2” indicates the number of bytes in 39 bytes.

In step S51, the main CPU 110a sets time measurement data for waiting for 6.5 seconds or more in order to output the chip external information after waiting for 6.5 seconds or more.
As described above, the reason for waiting for 6.5 seconds or more is that the rise time (7.5 seconds) from the power-on of the information management apparatus 200 is exceeded, and the external information for chips is stored in steps S60 to S63 described later. Output is performed. That is, since processing for waiting for 2 seconds has already been performed in the above step S1, a further waiting for 6.5 seconds or more in this step S51 will be described later when a total of 8.5 seconds or more has elapsed. In steps S60 to S63, external information for chips is output.

In step S52, the main CPU 110a outputs the initial value data corresponding to the chip external information and not specific to the gaming machine before outputting the chip external information specific to the gaming machine to the information management apparatus 200. Perform data initialization processing.
In this output data initial setting process, 8-bit external information serial data in which initial value data is set is set as output data.

  In step S53, the main CPU 110a performs serial data output processing for outputting the value of each bit of the 8-bit external information serial data to the second output port 112b in order from the least significant bit.

  In step S54, the main CPU 110a performs a clock signal output process for outputting a clock signal to the second output port 112b.

  In step S55, when the output of the 8-bit external information serial data is completed, the main CPU 110a performs a latch signal output process for outputting a latch signal to the second output port 112b.

In step S56, the main CPU 110a continuously outputs an enable signal to “chip information enable data” in the main RAM 110c in order to continuously output an enable signal indicating that the output of the chip external information is valid. Enable data initial setting processing for setting data to be performed is performed.
Thereafter, as long as the power is turned on, the enable signal is continuously output to the second output port 112b.

  In step S57, the main CPU 110a determines whether or not the power cutoff flag is ON. If it is determined that the power shutdown flag is ON, the process proceeds to step S67 to prepare for power interruption during information output. If it is determined that the power shutdown flag is not ON, the process proceeds to step S58.

  In step S58, the main CPU 110a updates the timing data set in step S51 and performs timing processing.

In step S59, the main CPU 110a refers to the timing data and determines whether 6500 ms has elapsed. If it is determined that 6500 ms has elapsed, the process proceeds to step S60 in order to output the chip external information unique to the gaming machine to the information management apparatus 200. If it is determined that 6500 ms has not elapsed, the process returns to step S52. .
As described above, until 6500 ms elapses, the standby processing is performed in which steps S52 to S58 are looped and the initial value data is continuously output.

In step S60, the main CPU 110a generates chip external information to generate chip external information unique to the gaming machine.
This external information generation for the chip reads the data of “first unique number” from the first unique number register 116, and also stores the data of “model name” from the model name storage area of the main ROM 110 b and the manufacturer name storage area of the main ROM 110 b. The “maker name” data is read out and 39-byte chip external information as shown in FIG. 7A is generated.
Then, 8-bit external information serial data is generated from the generated 39-byte chip external information bit data. For example, if the 0th bit of the first byte of the chip external information is “1”, serial data in which the third bit of the external information serial data is “1” is generated (see FIG. 20B).

  In steps S61 to S63, the main CPU 110a performs serial data output processing, clock signal output processing, and latch signal output processing in the same manner as in steps S53 to S55.

  In step S64, the main CPU 110a determines whether or not the power cutoff flag is ON. If it is determined that the power shutdown flag is ON, the process proceeds to step S67 to prepare for power interruption during information output. If it is determined that the power shutdown flag is not ON, the process proceeds to step S65.

In step S65, the main CPU 110a adds 1 to the “chip information serial transmission counter 1” in the main RAM 110c and updates it, assuming that output of one bit of the chip external information has been completed.
Then, the updated chip information serial transmission counter 1 is referred to. If the chip information serial transmission counter 1 is “11” (if 11 bits have been output), the “chip information serial transmission counter 2” in the main RAM 110c is set. 1 is added and updated, and “chip information serial transmission counter 1” is set to 0.

In step S66, the main CPU 110a determines whether or not the output of all bit data of the 39-byte chip external information has been completed. If it is determined that the output of all bit data of the 39-byte chip external information is not completed, the process returns to step S60, and if it is determined that the output of all bit data of the 39-byte chip external information is completed. Then, the chip external information output process is terminated.
Specifically, the chip information serial transmission counter 2 is referred to, and if the chip information serial transmission counter 2 is “39” (if 39 bytes are output), “0” is set to the chip information serial transmission counter 2. Then, the chip external information output process is terminated.

  In step S67, the main CPU 110a saves various data used in the main RAM 110c.

  In step S68, the main CPU 110a prohibits access to the main RAM 110c and protects the contents of the main RAM 110c. Then, an infinite loop is performed to prepare for power down.

(Timer interrupt processing of main control board)
The timer interrupt process of the main control board 110 will be described using FIG.

  A clock pulse is generated every predetermined period (4 milliseconds) by the CTC set in step S13, and a timer interrupt process described below is executed.

  First, in step S100, the main CPU 110a saves the information stored in the register of the main CPU 110a to the stack area.

  In step S110, the main CPU 110a updates the special symbol time counter, updates the special game timer counter such as the opening time of the special electric accessory, updates the normal symbol time counter, and updates the normal power release time counter. A time control process for updating various timer counters is performed. Specifically, a process of subtracting 1 from a special symbol time counter, a special game timer counter, a normal symbol time counter, and a general electricity open time counter is performed.

In step S120, the main CPU 110a performs a random number update process for the special symbol determination random number value, the big hit symbol random number value, the small hit symbol random number value, and the normal symbol determination random number value.
Specifically, each random number value and random number counter are updated by adding +1. When the added random number counter exceeds the maximum value in the random number range (when the random number counter makes one round), the random number counter is returned to 0, and each random number value is newly updated from the initial random number value at that time. .

  In step S130, as in step S30, the main CPU 110a updates the initial random number value for special symbol determination, the initial random number value for big hit symbol, the initial random number value for small hit symbol, and the initial random number value for normal symbol determination. Perform numerical value update processing.

In step S200, the main CPU 110a performs input control processing.
In this process, the main CPU 110a includes a general winning opening detection switch 12a, a first large winning opening detection switch 16a, a second large winning opening detection switch 17a, a first starting opening detection switch 14a, a second starting opening detection switch 15a, a gate. An input process for determining whether or not there is an input to each switch of the detection switch 13a is performed.

  Specifically, various detection signals from the general winning opening detecting switch 12a, the first big winning opening detecting switch 16a, the second large winning opening detecting switch 17a, the first starting opening detecting switch 14a, and the second starting opening detecting switch 15a. Is inputted, predetermined data is added to the prize ball counter used for the prize ball provided for each prize opening and updated.

  Furthermore, when a detection signal is input from the first start port detection switch 14a, if the data set in the first special symbol hold number (U1) storage area is less than 4, the first special symbol hold number ( U1) Add 1 to the storage area to obtain special symbol determination random number value, jackpot symbol random number value, small hit symbol random number value, reach determination random value, and special symbol variation random value The random number value is stored in a predetermined storage unit (0th storage unit to 4th storage unit) in the first special symbol random value storage area.

  Similarly, when a detection signal is input from the second start port detection switch 15a, if the data set in the second special symbol hold number (U2) storage area is less than 4, the second special symbol hold number (U2) 1 is added to the storage area, and a special symbol determination random number value, a big hit symbol random number value, a small hit symbol random number value, a reach determination random number value, and a special symbol variation random value are acquired. Various random numbers are stored in a predetermined storage unit (0th storage unit to 4th storage unit) in the second special symbol random number value storage area.

  When a detection signal is input from the gate detection switch 13a, if the data set in the normal symbol hold number (G) storage area is less than 4, the normal symbol hold number (G) storage area is set to 1. It adds, acquires the random number value for normal symbol determination, and memorize | stores the acquired random number value for normal symbol determination in the predetermined memory | storage part (0th memory | storage part-4th memory | storage part) in a normal symbol holding | maintenance storage area.

  Further, when a detection signal is input from the first grand prize opening detection switch 16a or the second big prize opening detection switch 17a, the number of game balls won in the first big prize opening 16 or the second big prize opening 17 is counted. 1 is added to the number of entries (C) storage area for the big winning opening to update.

  In step S300, the main CPU 110a performs a special drawing special electric control process for controlling the jackpot lottery, the special electric accessory, and the gaming state. Details will be described later with reference to FIG.

In step S400, the main CPU 110a performs a normal / normal power control process for controlling the normal symbol lottery and the normal electric accessory.
Specifically, it is first determined whether or not one or more data is set in the normal symbol hold count (G) storage area, and one or more data must be set in the normal symbol hold count (G) storage area. If this is the case, the current ordinary power transmission control process is terminated.
If 1 or more data is set in the normal symbol holding number (G) storage area, after subtracting 1 from the value stored in the normal symbol holding number (G) storage area, the data is in the normal symbol holding storage area. The normal symbol determination random numbers stored in the first storage unit to the fourth storage unit are shifted to the previous storage unit. At this time, the normal symbol determination random number value already written in the 0th storage unit is overwritten and erased.
Then, referring to the hit determination table shown in FIG. 8B, whether or not the normal symbol determination random number value stored in the 0th storage unit of the normal symbol hold storage area is a random value corresponding to “win”. Processing to determine is performed. Thereafter, the normal symbol display device 22 displays the fluctuation of the normal symbol. When the fluctuation time of the normal symbol elapses, the normal symbol corresponding to the result of the normal symbol lottery is stopped and displayed. If the random number for normal symbol determination referred to is “winning”, the start opening / closing solenoid 15c is driven to control the second start opening 15 to the second mode for a predetermined opening time.
Here, in the non-short-time gaming state, the variation time of the normal symbol is set to 29 seconds, and if it is “winning”, the second start port 15 is controlled to the second mode for 0.2 seconds. On the other hand, in the short-time gaming state, the normal symbol variation time is set to 0.2 seconds, and if it is “winning”, the second start port 15 is controlled to the second mode for 3.5 seconds. .

In step S500, the main CPU 110a performs a payout control process.
In this payout control process, the main CPU 110a refers to each prize ball counter, generates payout number designation commands corresponding to various winning ports, and transmits the generated payout number designation commands to the payout control board 130. To do.

  In step S600, the main CPU 110a performs external information data relating to game contents, start opening / closing solenoid data, first big prize opening / closing solenoid data, second big prize opening / closing solenoid data, special symbol display device data, and normal symbol display device data. Then, data creation processing of the memory number designation command is performed. Details will be described later with reference to FIGS. 16 and 17.

In step S700, the main CPU 110a performs output control processing. In this process, port output processing is performed for outputting signals of the external information data, the start opening / closing solenoid data, the first big prize opening / closing solenoid data, and the second big prize opening / closing solenoid data created in S600.
Further, the special symbol display device data and the normal symbol display device data created in S600 are used to turn on the LEDs of the first special symbol display device 20, the second special symbol display device 21 and the normal symbol display device 22. Display device output processing is performed. Further, command transmission processing for transmitting the command set in the effect transmission data storage area of the main RAM 110c to the effect control board 120 is also performed. Details will be described later with reference to FIG.

  In step S800, the main CPU 110a restores the information saved in step S100 to the register of the main CPU 110a.

(Special figure special electric control processing of main control board)
The special figure special power control processing of the main control board 110 will be described with reference to FIG.

First, in step S301, the value of the special figure special electricity processing data is loaded, the branch address is referred to from the special figure special electric treatment data loaded in step S302, and if the special figure special electric treatment data = 0, the special symbol memory determination process (step The process proceeds to S310). If the special symbol special power processing data = 1, the process proceeds to the special symbol variation processing (step S320). If the special symbol special power processing data = 2, the special symbol stop processing (step S330) is performed. If special figure special electric processing data = 3, the process moves to jackpot game processing (step S340), and if special figure special electric processing data = 4, the process moves to big hit game end processing (step S350). If special electric processing data = 5, the processing is shifted to the small hit game processing (step S360).
Since this “special drawing special electricity processing data” is set as needed in each subroutine of the special figure special electricity control processing as will be described later, the subroutine necessary for the game is appropriately processed. .

  In the special symbol memory determination process in step S310, the main CPU 110a performs a jackpot determination process, a special symbol determination process for determining a special symbol to be stopped and displayed, a variation time determination process for determining a variation time of the special symbol, and the like. Here, the specific content of the special symbol memory determination process will be described with reference to FIG.

(Special symbol memory judgment processing of the main control board)
FIG. 15 is a diagram illustrating a special symbol memory determination process of the main control board 110.

First, in step S311, the main CPU 110a determines whether one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area.
If one or more data is not set in any storage area of the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the special figure special electricity processing data = 0. The special symbol variation process of this time is terminated while holding.
On the other hand, if one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the process proceeds to step S312.

In step S312, the main CPU 110a performs a jackpot determination process.
Specifically, when one or more data is set in the second special symbol hold count (U2) storage area, 1 is calculated from the value stored in the second special symbol hold count (U2) storage area. After subtraction, various random numbers stored in the first to fourth storage units in the second special symbol random number storage area are shifted to the previous storage unit. At this time, various random values already written in the 0th storage unit are overwritten and deleted. Then, with reference to the jackpot determination table shown in FIG. 8 (a-2), the random number for special symbol determination stored in the 0th storage unit of the second special symbol random number storage area corresponds to “big hit”. It is determined whether it is a numerical value or a random value corresponding to “small hit”.
In addition, when one or more data is not set in the second special symbol hold number (U2) storage area and one or more data is set in the first special symbol hold number (U1) storage area, Various random numbers stored in the first to fourth storage units in the first special symbol random number storage area after subtracting 1 from the value stored in the first special symbol hold number (U1) storage area Is shifted to the previous storage unit. Also at this time, various random numbers already written in the 0th storage unit are overwritten and deleted. Then, with reference to the jackpot determination table shown in FIG. 8 (a-1), the random number value for special symbol determination stored in the 0th storage unit of the first special symbol random number storage area corresponds to “big hit”. It is determined whether it is a numerical value or a random value corresponding to “small hit”.
In the present embodiment, the random number value stored in the second special symbol random value storage area is shifted (digested) with priority over the first special symbol random value storage area. However, the first special symbol storage area or the second special symbol storage area may be shifted in the order of winning in the starting opening, and the first special symbol storage area is given priority over the second special symbol storage area. You may let them.

In step S313, the main CPU 110a performs a special symbol determination process for determining the type of special symbol to be stopped and displayed.
In this special symbol determination process, when it is determined as “big hit” in the jackpot determination process (step S312), the first special symbol random value storage area is referred to with reference to the symbol determination table shown in FIG. The jackpot symbol (special symbol 1 to special symbol 6) is determined based on the random number value for the jackpot symbol stored in the 0th storage unit. Further, when it is determined as “small hit” in the big hit determination process (step S312), the 0th memory of the first special symbol random value storage area is referred to with reference to the symbol determination table shown in FIG. 9B. The small hit symbol (special symbol A, special symbol B) is determined based on the random number value for the small bonus symbol stored in the section. If it is determined that the game has been “lost” in the big hit determination process (step S312), the lost symbol (special symbol 0) is determined with reference to the symbol determination table shown in FIG. 9C.
Then, stop symbol data corresponding to the determined special symbol is stored in the stop symbol data storage area.

In step S314, the main CPU 110a performs special symbol variation time determination processing.
Specifically, the variation pattern of the special symbol is determined based on the reach determination random number value and the special diagram variation random value stored in the 0th storage unit of the first special symbol random value storage area. Thereafter, the variation time of the special symbol corresponding to the determined variation pattern of the special symbol is determined. Then, a process of setting a counter corresponding to the determined variation time of the special symbol in the special symbol time counter is performed.

In step S315, the main CPU 110a sets, in a predetermined processing area, variation display data for causing the first special symbol display device 20 or the second special symbol display device 21 to perform special symbol variation display (LED blinking). . As a result, when the variable display data is set in the predetermined processing area, the LED lighting / extinguishing data is appropriately created in step S600, and the created data is output in step S700. Variation display of the special symbol display device 20 or the second special symbol display device 21 is performed.
Further, the main CPU 110a, when the special symbol variation display is started, the special symbol variation pattern designation command (the first special symbol variation pattern designation command) corresponding to the variation pattern of the special symbol determined in step S314. Alternatively, the second special symbol variation pattern designation command) is set in the effect transmission data storage area of the main RAM 110c.

  In step S316, the main CPU 110a sets the special symbol special electricity processing data = 0 to the special symbol special electric treatment data = 1, prepares to move to the special symbol variation processing subroutine, and ends the special symbol memory determination processing.

Again, the description of the special figure special electric control process shown in FIG. 14 will be returned.
In the special symbol variation process of step S320, the main CPU 110a performs a process of determining whether or not the special symbol variation time has elapsed.
Specifically, it is determined whether or not the variation time of the special symbol determined in step S314 has elapsed (special symbol time counter = 0), and if it is determined that the variation time of the special symbol has not elapsed The special symbol variation process is terminated while the special symbol special electricity processing data = 1 is held. Note that the special symbol variation time counter set in step S314 is subtracted in step S110.
If it is determined that the variation time of the special symbol has elapsed, the special symbol determined in step S313 is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21. Thereby, the special symbol is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21, and the player is notified of the jackpot determination result.
Also, when the number of time reduction (J)> 0, 1 is subtracted from the time reduction (J) counter and updated. When the number of time reduction (J) = 0, the time reduction game flag is cleared and the number of high probability games (X )> 0 is updated by subtracting 1 from the high probability game number (X) counter, and if the high probability game number (X) = 0, the high probability game flag is cleared.
Finally, the special symbol special power processing data = 1 is set to the special symbol special power processing data = 2, preparation is made to move to a special symbol stop processing subroutine, and the special symbol variation processing is terminated.

In the special symbol stop process in step S330, the main CPU 110a performs a process of determining whether the special symbol that is stopped and displayed is a “big hit symbol”, a “small bonus symbol”, or a “losing symbol”. Do.
If it is determined that the game is a jackpot symbol, the data stored in the gaming state storage area is referred to and data (00H to 03H) indicating the current gaming state is set in the gaming state buffer. Thereafter, the data (high probability game flag and short time game flag), high probability game number (X) counter, and short time number (J) counter stored in the high probability game flag storage area and the short time game flag storage area are cleared. . Further, the special figure special power processing data = 2 is set to the special figure special electric processing data = 3, preparation is made to move to the jackpot game processing subroutine, and the special symbol stop processing is ended.
In addition, when it is determined that the small winning symbol, the data stored in the game state storage area is not cleared, and the special figure special electric processing data = 2 to the special figure special electric treatment data = 5 is set. The special symbol stop process is completed by making preparations for transferring to a winning game process subroutine.
On the other hand, if it is determined that the symbol is a lost symbol, the special symbol special electric processing data = 2 is set to special special electric symbol processing data = 0, and the special symbol memory determination processing subroutine is prepared for the special symbol stop processing. finish.

In the jackpot game process of step S340, the main CPU 110a determines which jackpot of the long hit or short hit is executed, and performs a process of controlling the determined jackpot.
Specifically, the jackpot release mode is determined based on the type of jackpot symbol (stop symbol data) determined in step S313.
Next, in order to execute the determined jackpot opening mode, an opening time corresponding to the type of jackpot is set in the special game timer counter, and the first big winning opening opening / closing solenoid 16c (or the second big winning opening opening / closing solenoid) is set. 17c) is output to open the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b). At this time, 1 is added to the round game count (R) storage area.
When a predetermined number of game balls enter during the opening or when the opening time of the big prize opening has elapsed (the number of the big prize opening (C) = 9 or the special game timer counter = 0), The output of the drive data of the big prize opening / closing solenoid 16c (or the second big prize opening / closing solenoid 17c) is stopped, and the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b) is closed. Thereby, one round game is completed. This round game control is repeated 15 times.
When the 15 round games are completed (round game count (R) = 15), the data stored in the round game count (R) storage area and the number of winning prize entrance (C) storage areas are cleared, The special figure special electric processing data = 3 is set to the special figure special electric treatment data = 4, preparation is made to move to the big hit game end processing subroutine, and the big hit game processing is ended.

In the big hit game ending process in step S350, the main CPU 110a determines either the high probability game state or the low probability game state, and the game state of either the short-time game state or the non-short-time game state. Perform the decision process.
Specifically, based on the data stored in the game state buffer and the type of jackpot symbol (stop symbol data) determined in step S313, the setting of the high probability game flag, the number of high probability games (X) , Time-short game flag, time-short number of times (J).
For example, if the special symbols 1 to 3 and 5 corresponding to the probability variation jackpot, the high probability game flag is set in the high probability game flag storage area, and the high probability game number (X) counter is set to 10,000 times. Further, if the special symbols 1 to 3 and 5 corresponding to the probability variation jackpot are set, the time-short game flag is set in the time-short game flag storage area, and the time-short-time (J) counter is set to 10,000 times. On the other hand, if the special symbols 4 and 6 correspond to the normal jackpot, the high probability game flag is not set and the high probability game number (X) counter is set to zero. Further, if the special symbol 4 or 6 corresponding to the normal jackpot, the short time game flag is set, and the short time number (J) counter is also set to 100 times.
After that, the special symbol special power processing data = 4 is set to the special symbol special power processing data = 0, and preparation for moving to the special symbol memory determination processing subroutine is made, and the big hit game end processing is ended.

In the small hit game processing in step S360, the main CPU 110a determines the small hit release mode based on the type of small hit symbol (stop symbol data) determined in step S313.
Next, in order to execute the determined small hit opening mode, the small hit opening time is set in the special game timer counter, and the driving data of the second big winning opening / closing solenoid 17c is output to output the second big winning prize. The mouth opening / closing door 17b is opened. At this time, 1 is added to the number-of-releases (K) storage area.
When the small winning opening time elapses (special game timer counter = 0), the drive data output of the second big prize opening / closing solenoid 17c is stopped and the second big prize opening / closing door 17b is closed. The opening / closing control of the second big prize opening opening / closing door 17b is repeated 15 times.
Then, the opening / closing control of the second grand prize opening / closing door 17b is performed 15 times, or a predetermined number of game balls enter the second big prize opening 17 (the number of times of opening (K) = 15 or the grand prize opening entrance) Number (C) = 9), in order to end the small hit game, the output of the drive data of the second large winning opening / closing solenoid 17c is stopped, the number of times of opening (K) storage area and the number of winning winning holes (C) Clear the data stored in the storage area, set special figure special electricity processing data = 5 to special figure special electricity treatment data = 0, and prepare to move to a special symbol memory judgment processing subroutine. The winning game process is terminated.

(2) A process for creating signal data to be output to the special symbol hold indicator 24 or the normal symbol hold indicator 25 is performed.

  In step S620, the main CPU 110a performs external information generation processing for generating external information related to game content. Details will be described with reference to FIG.

(External information generation processing)
The external information generation process will be described with reference to FIG.

In step S620-1, the main CPU 110a loads the data stored in the special figure special electricity processing data storage area, and determines whether or not special figure special electric treatment data = 2. That is, it is determined whether the special symbol stop process is in progress.
If special figure special power processing data = 2, the process proceeds to step S620-2, and if special figure special power processing data = 2, the process proceeds to step S620-3.

  In step S620-2, the main CPU 110a performs a symbol determination signal generation process. Specifically, 8-bit external information serial data including a symbol determination signal (1-bit data) indicating the number of times the special symbol fluctuates is generated. For example, serial data in which the 0th bit of the external information serial data is “1” is generated (see FIG. 20B).

In step S620-3, the main CPU 110a loads the data stored in the special figure special electricity processing data storage area, and determines whether or not special figure special electric treatment data = 3. That is, it is determined whether or not the jackpot game process is in progress.
If special figure special power processing data = 3, the process proceeds to step S620-4. If special special figure special power processing data = 3, the external information generation process is terminated.

  In step S620-4, the main CPU 110a performs a jackpot signal generation process. Specifically, referring to the stop symbol data storage area, based on the stop symbol data (type of jackpot), an 8-bit external including jackpot signals 1 and 2 (1 bit data) indicating the type of jackpot Generate information serial data. For example, serial data in which the first bit or the second bit of the external information serial data is “1” is generated (see FIG. 20B).

Process to output to.

In step S720, the main CPU 110a performs a second port output process.
In the second port output process, the value of each bit of the 8-bit external information serial data generated in step S620-2 or step S620-4 is output to the second output port 112b in order from the least significant bit, and the clock The signal and the latch signal are also output to the second output port 112b.

In step S730, the main CPU 110a performs command output processing.
In the command output process, in order to transmit the command to the effect control board 120, the command set in the effect transmission data storage area of the main RAM 110c is output to the third output port 112c.

  Next, the outline of the effect control board 120 will be briefly described.

  When the effect control board 120 receives a command transmitted from the main control board 110, a command reception interrupt process of the effect control board 120 occurs, and the received command is stored in the reception buffer.

  Then, the sub CPU in the effect control board 120 analyzes the received command and generates various commands corresponding to each command in the timer interrupt process of the effect control board 120 performed every 2 ms. Thereafter, the generated various commands are transmitted to the image control board 150 and the lamp control board 140.

  For example, when the sub CPU in the effect control board 120 receives the variation pattern designation command from the main control board 110, the sub CPU analyzes the content of the received variation pattern designation command, and the liquid crystal display device 31, the audio output device 32, the effect drive. A command for causing the device 33 and the effect lighting device 34 to execute a predetermined effect is generated, and the command is transmitted to the image control board 150 and the lamp control board 140.

  Next, the outline of the lamp control board 140 and the image control board 150 will be briefly described.

  In the lamp control board 140, upon receiving the production command from the production control board 120, the production drive device operation program is read based on the received production command, and the production drive device 33 is operated and controlled. The effect lighting device control program is read based on the received effect command, and the effect lighting device 34 is controlled.

  In the image control board 150, when the production command is received from the production control board 120, the audio CPU reads out the audio output device control program from the audio ROM based on the received production command, and the audio in the audio output device 32 is read. And the host CPU 150a reads the animation control program from the image ROM and controls the image display on the liquid crystal display device 31.

  Next, processing executed by the management CPU 200a in the information management apparatus 200 will be described.

(Main processing of the information management apparatus 200)
The main process of the information management apparatus 200 will be described with reference to FIG.

  In step S1000, the management CPU 200a performs an initialization process. In this process, the management CPU 200a reads the main process program from the management ROM 200b and initializes and sets a flag stored in the management RAM 200c in response to power-on. If this process ends, the process moves to a step S1001.

In step S1001, the management CPU 200a performs a connection confirmation process with the information control device 300, the information collection server 400, and the like provided in each game store.
In the present embodiment, it takes about 6.5 seconds from the time the power is turned on to the information management apparatus 200 to the completion of the processes in steps S1000 and S1001.

In step S1100, the management CPU 200a performs a gaming machine connection confirmation process.
In this connection confirmation process, a connection confirmation with the payout control board 130 of the gaming machine 1 is performed, and a confirmation process such as whether the payout is ready is performed.

In step S1200, the management CPU 200a performs a ball lending control process.
In this ball lending control process, when a ball lending signal based on the ball lending switch 135 is input from the payout control board 130 of the gaming machine 1, the monetary information of the money information medium (IC card or the like) accepted by the information management device 200 is confirmed. After that, a payout permission signal permitting the game machine 1 to pay out a specified number of game balls is output to the payout control board 130. At this time, the money information of the money information medium (IC card or the like) is also updated.

In step S1300, the management CPU 200a performs a card return control process.
In this card return control process, when a return signal based on the return switch 136 is input from the payout control board 130 of the gaming machine 1, control is performed to return a monetary information medium (IC card or the like) accepted by the information management device 200. .

In step S1400, the management CPU 200a performs external information input analysis processing.
In this external information input analysis process, when external information for chips is input from the game information output terminal board 30 of the gaming machine 1, it is determined whether the one-chip microcomputer 110m is illegal based on the input external information for chips, The chip external information is transmitted to the information collection server 400 via the Internet.
Thereafter, the processes in steps S1100 to 1400 are repeated.

Based on the above, game control processing performed by the one-chip microcomputer 110m and signal output to the second output port 112b will be described together with reference to FIG.
FIG. 20A is a diagram showing the relationship between the game control process and the signal to the output port, and FIG. 20B shows the configuration of the external information serial data output to the second output port 112b. FIG.
The “game control process” referred to here indicates an overall process performed by the one-chip microcomputer 110m shown in FIGS.

(Game control processing and signal to output port)
First, when the gaming machine 1 is powered on, the one-chip microcomputer 110m (main CPU 110a) performs a standby process of waiting for 2000 ms after performing a security check (see step S1).

  Thereafter, after lapse of 2000 ms, initialization processing (see step S2) and output control command (power restoration preparation command / RAM clear acceptance designation command) output processing (see steps S6 and S10) are performed.

  Here, since the rise time from the power-on of the liquid crystal display device 31 of the present embodiment is about 1500 ms, after the liquid crystal display device 31 is started up, the production control command (power restoration preparation command / RAM clear acceptance designation command) ) Is output.

  Since the rise time from the power-on of the information management apparatus 200 of this embodiment is about 7500 ms, the initial value data of the chip external information is passed after 2000 ms to wait for the information management apparatus 200 to start up. Is output for 6500 ms (see steps S7 and S11).

  When 6500 ms elapses, the chip external information (including the unique number of the gaming machine 1) is output. As a result, after the information management apparatus 200 is started up, the external chip information unique to the gaming machine 1 can be output to the information management apparatus 200.

  Thus, even when the rise time of the information management device 200 is longer than that of the liquid crystal display device 31, the production control command is first output to the liquid crystal display device 31 and the information management device 200 waits for the rise. Since the chip external information unique to the gaming machine 1 is output to the information management device 200, a signal can be output quickly without waiting for all devices to rise. In particular, since an effect control command is first output to the liquid crystal display device 31, a store clerk or the like of the game store can recognize that the one-chip microcomputer 110m of the gaming machine 1 is officially activated.

  Here, as shown in FIG. 20B, in the external information serial data output to the second output port 112b, the 0th bit indicates the “symbol determination signal” and the 1st bit indicates “the jackpot signal 1”. The second bit indicates “big hit signal 2”, the third bit indicates “external information signal”, and the fourth to seventh bits are configured as blank data. The fourth to seventh bits may be configured to indicate predetermined information.

  When waiting for 6500 ms, “1” as the initial value data of the chip external information, the clock signal, the latch signal, and the enable signal are continuously output. That is, the external information serial data whose third bit is “1”, the clock signal, the latch signal, and the enable signal are continuously output (see steps S52 to S56).

Thereafter, when 6500 ms elapses, the external information for the chip unique to the gaming machine 1 is output to the information management apparatus 200. That is, 39-byte chip external information is output while the third bit of the external information serial data is set to “1” or “0”.
It takes 2145 ms to complete the output of the 39-byte chip external information as shown in FIG. 7 because the baud rate is 200 bps.

  When the output of 39-byte chip external information is completed, the normal game loop process (see steps S20 and S30) is started. When a timer interrupt occurs, the timer interrupt process (see FIG. 13) is executed. When the interrupt process ends, the normal game loop process is executed again.

  As described above, after the game machine 1 is powered on, after executing the normal game loop process and the timer interrupt process, the chip external information is not output, so that the chip external information for preventing fraud is output. However, the load of the game control processing of the one-chip microcomputer 110m (main CPU 110a) can be reduced.

  In the present embodiment, the information management apparatus 200 is configured to perform ball lending control that allows a specified number of game balls to be paid out to the gaming machine 1, but without performing ball lending control, A configuration that only collects and manages information related to the gaming machine 1 may be used.

  In the present embodiment, the chip external information to be output to the information management apparatus 200 is configured to be output by serial communication, but may be configured to be output by parallel communication.

  In the present embodiment, the configuration of the external information for chips is composed of three pieces of information of “model name”, “manufacturer name”, and “first unique number” as shown in FIG. 7A. , It may be composed of information of only the “first unique number”.

  Furthermore, in the present embodiment, the external information for chips is composed of three pieces of information of “model name”, “manufacturer name”, and “first unique number” as shown in FIG. 7A. However, you may comprise including the information regarding other game content. For example, it may be composed of four types of information: “model name”, “manufacturer name”, “first unique number”, and “gaming state” indicating the gaming state of the gaming machine.

  Moreover, according to this embodiment, although the game machine used for a pachinko game machine was demonstrated, you may use for a swing type game machine (slot machine), a jigball game machine, and an arrangement ball game machine.
