Description

  The present invention relates to a ball game machine that plays a game by launching a game ball on a game area of a game board surface, and more particularly, to a configuration of a communication circuit of a control board mounted on the ball game machine.

  In recent ball game machines, the game control board (also referred to as the main control board), which controls the progress of games with the main purpose of countering fraud, is equipped with a security function that checks for illegal modifications to the ROM. A configuration of a one-way communication circuit capable of transmitting only to the various control boards is employed. The reason for adopting this one-way communication circuit configuration is to prevent unauthorized modification such as outputting an illegal signal from other various control boards to the game control board. These measures have further improved the soundness of the ball game machine.

  In such a gaming machine, an invention has been made to reduce the processing burden on the game control board and prevent fraud. For example, in Patent Document 1, a command according to game content is transmitted from the main board 14 that controls the progress of the game to the command processing board 50 so that bidirectional communication is not possible (paragraph 0018). The invention which outputs to the symbol display board | substrate 30, the electrical decoration control board | substrate 28, and the speaker 7 is disclosed.

  In Patent Document 2, a command corresponding to the game content is transmitted from the main board 14 that controls the progress of the game to the symbol display board 30, and the illumination control board 28 and the speaker 7 are transmitted based on the command received by the symbol display board 30. An invention to output is disclosed. Thus, the main board 14 and the command processing board 50 or the symbol display board 30 that receives the command are configured so as not to be able to perform bidirectional communication (paragraph 0023), thereby preventing illegal acts.

In Patent Document 3, a command signal transmitted from the main control board 1 is configured to be able to be transmitted to the plurality of sub control boards 2, 3, 4 via the command signal transmission relay board 5.

That is, in order to perform an illegal act from the symbol control board to the main control board, it is necessary to perform wiring that can be transmitted from the symbol control board to the main control board. However, it has been difficult to find fraudulent acts caused by such unauthorized wiring.

  In Patent Document 3, a command signal transmitted from the main control board 1 is sent to the lamp control board 2, the voice control board 3, and the symbol control board 4, which are a plurality of sub control boards, via the command signal transmission relay board 5. Each is configured to be able to transmit individually, but there is no description of one-way communication from the main control board 1 to the relay board 5, the input / output circuit 8 is bidirectional, and the sub-control board for both communication from the game control board (main control board).

In this connection, since the circuit configuration is such that data is transmitted only from the game control board 30 to the image control board 33, the fraudulent acts are difficult to perform, and the fraudulent acts are easily found. That is, in order to perform an illegal act from the image control board 33 to the game control board 30, it is necessary to perform an illegal action on the double one-way communication circuit, and the first relay board 37a is equipped with a CPU. This is because it is easy to detect a fraudulent act directly from the first relay board 37a.

  That is, in order to perform an illegal act on the game control board 30 from the image control board 33, it is necessary to perform wiring that can be transmitted from the image control board 33 to the game control board 30. However, since the game control board 30 and the image control board 33 are connected via the first relay board 37a, the image control board 33 and the game control board 30 are connected without passing through the first relay board 37a. Wiring can be considered to be due to fraud. Conventionally, even a one-way communication circuit has not been routed through the first relay board 37a, so that it has not been easy to find wiring due to fraud. On the other hand, it is conceivable to play an illegal game against the game control board 30 by wiring from the first relay board 37a due to an illegal act. However, since the first relay board 37a is configured as a board on which the CPU is not mounted, unauthorized modification can be easily found.

Demonstrate. That is, in order to perform an illegal act from the frame lamp control board 35 (or the launch control board 49) to the prize ball control board 31, it is necessary to perform an illegal action on the double one-way communication circuit. This is because the second relay board 37b is a board on which the CPU is not mounted, and a direct fraud from the second relay board 37b is easily detected.

  Furthermore, the image control board 33 and the sound / lighting control board 34 are two-way communication, and the image display control is performed while the configuration is made to prevent fraud by providing two sets of two one-way communication circuits. Can be perfectly synchronized with the illumination control, and has an effect of precisely matching the image control with the illumination control and / or the sound effect control.

  Data from the winning ball control board 31 is transmitted to the launch control board 49 via the second relay board 37b and the frame lamp control board 35, or is sent to the frame lamp control board 35 via the launch control board 49. It is possible to precisely correspond sound / electricity control related to launch control and image display.

By configuring, space saving of the internal structure of the ball game machine can be achieved.

  According to the invention of claim 4, as in the invention of claim 1, as shown in FIG. 3, no CPU is mounted between the image control board 233 or the launch control board 249 and the game control board 230. The relay board 237 is interposed, and in the connection before and after the relay board 237, the circuit configuration is such that data is transmitted only from the game control board 230 to the image control board 233 or the launch control board 249. Exerts the effect of being easy. That is, in order to perform an illegal act on the game control board 230 from the image control board 233 or the launch control board 249, it is necessary to perform an illegal action on the double one-way communication circuit. This is because it is easy to detect a fraudulent act directly from the relay board 237 because it is a board without a CPU.

  According to the invention of claim 5, in addition to having the same effect as the invention of claim 4, as shown in FIG. 4, in the bullet ball game machine according to claim 3, from the launch control board 249 to the sound / electric decoration control board. Since the one-way communication circuit for transmitting data to 234 is provided, an abnormality or the like of the launch control board 249 can be notified by the sound / lighting control board 234 or the image control board 333.

  According to the invention of claim 6, as in the invention of claim 1, as shown in FIG. 5, a CPU is interposed between the image control board 333 and the game control board 330 (or the sound / lighting control board 334). A relay board 337 that is not mounted is interposed, and in the connection before and after the relay board 337, the circuit configuration is such that data is transmitted only from the game control board 330 to the image control board 333 (or sound / lighting control board 334). It is difficult to perform and exhibits the effect that it is easy to find fraud. That is, in order to perform an illegal act on the game control board 330 from the image control board 333 (or sound / lighting control board 334), it is necessary to perform an illegal action on the double one-way communication circuit. Further, since the relay board 337 is a board on which the CPU is not mounted, a direct fraud from the relay board 337 is easily detected.

  In addition, since the sound / lighting control board 334 or the image control board 333 detects the operation state of the effect switch 338, it is possible to prevent an illegal act from the effect switch 338.

  According to the first to sixth aspects of the present invention, the image control board 33 and the sound / lighting control board 34 have a circuit configuration capable of bidirectional communication, can improve communication reliability, and display contents. Consistency with sound effects and electrical decoration can be further enhanced.

Processing executed by an 8-bit one-chip microcomputer (hereinafter simply referred to as “microcomputer”) in the game control board 30 of the pachinko machine 10 having the circuit configuration described above will be described according to the flowchart shown in FIG.
The flowchart shown in FIG. 10 represents a main process executed by the microcomputer of the game control board 30 and is a process periodically executed by a hardware interrupt about every 2 ms. In the first embodiment, each process from step S100 to S200 is a process that is executed only once in the interrupt process, and is referred to as “main process”. As long as time is allowed within the remaining time after executing this main process. The processing of steps S210 and S220 that are repeatedly executed is referred to as “residual processing”.

When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (step S100). This determination process is performed by determining whether or not the value of a predetermined area of the RAM as a memory is a predetermined value. When the process executed by the microcomputer shifts to this process, the normal process is executed. This is to determine whether or not If it is not normal, microcomputer runaway due to noise or the like may be considered when power is turned on, but microcomputer runaway may be considered to be almost impossible due to recent technological improvements, and is usually at power on. When the power is turned on, the value in the predetermined area of the RAM is different from the predetermined value.
When it is determined that the memory is not normal, each initial value is written to the memory work area, such as writing a predetermined value in the predetermined area of the memory, and using a special symbol and a normal symbol as an initial symbol, that is, initial setting is performed ( In step S110), the process proceeds to a residual process.

If an affirmative determination is made, initial random number update processing is first executed (step S120). As shown in FIG. 11, this process is an increment process that increments the value of the initial random number by 1 each time this process is executed. The process increments the initial random number value by 1 before the process is executed. When the random number value is “249”, which is the maximum value, the initial value is returned to “0” in the next process, and 250 integers from “0” to “249” are repeatedly generated in ascending order.
The success / failure random number update process (step S130) subsequent to step S120 is an increment process that increments by one each time the process is executed, similar to the initial random number update process, but as shown in FIG. 12, the maximum value is “249”. In the next processing, the initial random number at that time is set to the initial value (hereinafter referred to as “update initial value”), and the process of incrementing by +1 for each interrupt is continued to be “1” less than the update initial value. When the value (hereinafter referred to as “update maximum value”) is reached, the initial random number at that time is used as the initial value, and 250 integer values from “0” to “249” are repeatedly created. .

  That is, +1 is added for each interrupt processing, and setting the elements constituting the random number to an integer value from “0” to “249” is not different from the initial random number. In this interrupt processing, the update initial value at that time is set as the initial value, and +1 is added for each interrupt until the update maximum value is reached, and the next update initial value is set as the initial value. As a result, the success / failure random numbers are 250 integer values from “0” to “249” as elements constituting the random numbers, and are incremented by +1 for each interrupt process. Since it is changed to a value determined by the initial random number, the value of the random number can be made unpredictable. In addition, the constituent elements of the random number determined by the update initial value and the update maximum value are not different from the 250 integer values of “0” to “249” that are the same as the conventional pass / fail random numbers, and thus the elements constituting the random number The appearance rate is made uniform.

The jackpot symbol random number update process (step S140) is configured as a counter that repeatedly creates 15 integers “0” to “14”, and is incremented by 1 every time this process is exceeded and is an initial value “0”. Return to. Each of the 15 random numbers “0” to “14” is “000”, “111”, “222”, “333”, “444”, “555”, “ 666 ”,“ 777 ”,“ 888 ”,“ 999 ”, [AAA],“ BBB ”,“ CCC ”,“ DDD ”,“ EEE ”, respectively.
The off symbol random number update process (step S150) is composed of a random symbol for the left symbol, a random number for the middle symbol, and a random number for the right symbol, and is used as a miss symbol when it is not a big hit. The left symbol random number is configured as a counter that repeatedly generates 15 integers “0” to “14”, and is incremented by 1 every time this process is exceeded, and returns to the initial value “0”. The middle symbol random number is configured as a counter that repeatedly creates 15 integers “0” to “14”. When the left symbol random number returns to “0”, the process is incremented by 1 and exceeds the maximum value. Return to "0". The right design random number is configured as a counter that repeatedly creates 15 integers from “0” to “14”. When the medium design random number returns to “0”, it is set to 1 every time this process is exceeded and exceeds the maximum value. Return to "0".
The normal symbol random number update process (step S160) is configured as a counter that repeatedly generates seven integers “0” to “6”, and is incremented by 1 in this process and becomes the initial value “0” when the maximum value is exceeded. Return.

The initial random number, the success / failure random number, the big hit symbol random number, the off symbol random number, and the normal symbol random number are respectively updated by each of the random number update processing (steps S120 to S160) described above. The input processing of each switch connected to the game control board 30 is executed. In the first embodiment, the full switch 43, the replenishment switch 44, the first type start port switch 36a, the V switch 40a, the count switch 40b, the normal symbol operation switches 38a and 39a, and the other winning port switch 48, etc. A process for checking the operating status is executed.
When there is an input to the first type start port switch 36a by this input process, it is the time when a game ball wins the ordinary electric accessory 36 as the start port, and the value of the success / failure random number at the time of this interrupt process is extracted. The result is compared with an appropriateness determination value.

The pachinko machine 10 according to the first embodiment is configured as a probability variation machine, and the success / failure determination value is “1” at the normal probability, and “1”, “3”, “5”, “7”, “ 9 ”. As described above, the appearance rate of each of the 250 integer values “0” to “249” constituting the random number is uniform, and is extracted at the timing when the game ball wins the ordinary electric accessory 36 as the starting port. The value of the random number is a randomly extracted value because the winning timing cannot be adjusted in minute time units as compared with 2 ms which is the minute time of the hard interrupt, and the wrong number functions as a complete random number. Accordingly, the probability that the extracted value of the random number of hit / fail matches the hit / fail judgment value and is a big hit is 1/250 at the normal probability and 1/50 (= 5/250) at the high probability. In the first embodiment, the probability of generating the jackpot is shifted from the low probability state to the high probability state. In the first embodiment, the value of the jackpot symbol random number in the interrupt processing when the jackpot occurs is “1”, “3”, “ 5 ”,“ 7 ”,“ 9 ”,“ 11 ”, and“ 13 ”(hereinafter referred to as“ high-probability random value ”), with a high probability of 7/15 when a jackpot occurs. Transition. If the value of the jackpot symbol random number when the jackpot is generated again during the high probability is high, the higher probability state continues. That is, every time the high probability state is entered, there is a possibility that the high probability continues with a probability of 7/15.
When the success / failure determination process (step S180) ends, an image output process (step S190) is subsequently executed. This image output process will be described in detail later.

  In each subsequent output process (step S200), the game control board 30 responds to various solenoids such as the prize ball control board 31, the image control board 33, the big prize opening solenoid 40c, and the launch control board 49 according to the progress of the game. Each output process is executed. That is, when it is detected by each input process (step S170) that there is a winning game ball at each winning opening on the surface of the game board 22, the prize ball control board 31 is awarded to pay out the gaming ball as a winning ball. When the pachinko machine 10 has an abnormality in the process of outputting the ball data, a process of outputting an error signal to the image control board 33 to notify that there is an error, and a big hit process when a big hit occurs, Execute.

  The remaining process subsequent to the above-described process is composed of an outlier symbol random number update process (step S210) and an initial random number update process (step S220), which are exactly the same as the above-described steps S150 and S120, respectively. These two processes form an infinite loop and are repeatedly executed as long as time is allowed until the next interrupt is executed. The time required to execute this processing from steps S100 to S200 described above differs for each interrupt depending on whether or not to execute the jackpot processing, the difference in the display mode of special symbols, and the like. As a result, the number of times the remaining process is executed is different for each interrupt, and the interrupted process shown in FIG. 10 is performed once, and the values of the design random numbers and the initial random numbers that are updated (added) are not uniform. . Thereby, there is no possibility that the initial random number and the out-of-sequence random number are synchronized with the random number. In the first embodiment, since the update of the random number is changed according to the value of the initial random number, there is no possibility of synchronization. The normal symbol random number update process (step S160) described above may also be executed in the remaining process.

By executing the processes described above, the pachinko machine 10 performs the following operations.
In accordance with the amount of rotation of the launch handle 24 operated by the player, a launch ball 49 is launched onto the game board 22 by the launch motor 49a, and the launched game ball is awarded to the ordinary electric accessory 36 as the first type starting port. Then, it is detected by the first type start port switch 36a, and operates to display the special symbols on the screen of the LCD 32a on the screen of the LCD 32a after being variably displayed for a predetermined time. When the special symbol displayed statically displays a predetermined specific symbol, for example, the same three-digit symbol such as “777”, the game content advantageous to the player is provided as a big hit state. Whether or not the big hit state is reached depends on whether or not the value of the random number that is extracted when the game ball is detected by the first type start port switch 36a provided in the ordinary electric accessory 36 is a predetermined value. It is determined.

When the big hit state is reached, the grand prize opening 40 is opened for about 30 seconds or until 10 seconds when the game is won by the count switch 40b, whichever comes first. When the V switch 40a detects that the game ball has passed through the special area, the special winning opening 40 is once closed and then opened again, and this opening operation is repeated up to 16 times. Normally, 15 game balls are paid out as a prize ball for one game ball winning, so when one big hit state occurs, about 2400 (= 15 × 10 × 16) A game ball can be obtained as a prize ball. This prize ball discharge operation is executed by the prize ball control board 31 and the launch control board 49. The V solenoid 40d that opens and closes the special area of the special winning opening 40 closes the special area when one game ball passes through the special area.
The normal electric accessory 36 wins the game ball even in a normal state, but when the value of the normal symbol random number extracted at the timing when the game ball passes through the normal symbol operation gate 38 or 39 is a predetermined value, The entrance is enlarged and winning becomes easier. The time for the entrance of the ordinary electric accessory 36 to expand is 0.3 seconds in the normal state, and 1.5 seconds at the high probability described above. Also, the normal symbol change time from when the game ball passes through the normal symbol operation gate 38 or 39 until it fluctuates and stops is 20 seconds in the normal state, and 5 seconds to 6 seconds at high probability. . Thereby, at the time of high probability, the number of times of deriving the determination result as to whether or not to enlarge the entrance of the ordinary electric accessory 36 by the ordinary symbol can be made larger than that in the normal state.

Here, the above-described image output process (step S190) will be described in detail with reference to FIG. The command code shown in FIG. 14 is a code transmitted from the game control board 30 to the image control board 33 via the first relay board 37a.
As shown in FIG. 14, the transmission command codes of the game control board 30 and the image control board 33 of the first embodiment are 1. 1. When power is turned on 2. Demonstration waiting for customers. 3. During design fluctuation. 4. At the start of jackpot During the big hit, 6. 6. At the end of jackpot It can be roughly divided into 7 types when operation is abnormal.

1. When the power is turned on, the command when the power is turned on is a command code transmitted from the game control board 30 to the image control board 33 when the pachinko machine 10 is turned on, and includes 2 bytes of an operation number of 10H and an identification number of 01H. It consists of instructions. When the image control board 33 receives this command, a demonstration screen at power-on is displayed on the screen of the LCD 32a according to the control program written in the ROM.

2. Customer Waiting Demo The customer waiting demo command is a command that is sent after the power-on demo screen is completed or when it is determined that the player has not played a game for a predetermined time (usually about 3 minutes). Yes, it consists of a 2-byte instruction with an operation number of 20H and an identification number of 01H. When the image control board 33 receives this command, a demo screen waiting for the customer is displayed on the screen of the LCD 32a according to the control program written in the ROM. For example, all the special symbol variation patterns that are variably displayed on the special symbol display areas 50a to 50c shown in FIG. 13 are sequentially displayed. Further, the on-hold storage display portions 51a to 51d are sequentially turned on and displayed. At this time, a background image and a character corresponding to each variation pattern are displayed on the background screen 52. This waiting-for-customer demonstration screen displays all the variation patterns in order until the player operates the firing handle 24, and then repeatedly displays them. Note that a player executes a game for a predetermined time when there is no winning for a predetermined time in any or all of the winning holes, or a switch is provided in the out port 41 of the game board 22 and this switch is not turned on for a predetermined time. It is preferable to adopt a configuration in which it is determined that there is not.

3. The symbol changing command is a command transmitted when the special symbol changes. As shown in FIG. 14, (1) basic variation pattern code, (2) left stationary symbol designation code, and (3) middle stationary symbol designation. 4 types of command codes (hereinafter, these four command codes may be collectively referred to as “image display commands”).

(1) Basic variation pattern code The basic variation pattern code is configured as a total of nine types of two-byte instructions, one byte instruction of 30H as the operation number and nine types of one-byte instructions of 01H to 09H as the identification numbers. . These nine types of 1-byte instructions will be described in detail later.
(2) Left stationary symbol designation code The left stationary symbol designation code is an instruction code consisting of an operation number of 31H and 15 types of identification numbers of 01H to 0FH. When the identification number is 01H, the left stationary symbol designation code is “0”. "1" for 02H, "2" for 03H, "3" for 04H, "4" for 05H, "5" for 06H, "6" for 07H, “7” for 08H, “8” for 09H, “9” for 0AH, “A” for 0BH, “B” for 0CH, “C” for 0DH, 0EH In the case of “D”, the character “E” is displayed in the special symbol display area 50a as a special symbol.

(3) Medium stationary symbol designation code The middle stationary symbol designation code is an instruction code consisting of 32H operation number and 15 types of identification numbers 01H to 0FH. The identification number is the identification number of the left stationary symbol designation code. The characters having the same meaning are designated as special symbols in the special symbol display area 50b.
(4) Right stationary symbol designation code The right stationary symbol designation code is an instruction code composed of an operation number of 33H and 15 types of identification numbers of 01H to 0FH. The identification number is an identification number of the left stationary symbol designation code. The characters having the same meaning are displayed in the special symbol display area 50c as special symbols.
This variable time code, left, middle and right stationary design designation codes are command codes transmitted almost every 2 bytes when a game ball launched on the game board 22 wins the ordinary electric accessory 36 as a starting port. The contents are determined as follows.

  As described above, when the game ball wins the ordinary electric accessory 36, the value of the success / failure random number, the value of the jackpot symbol random number, the value of the off symbol random number, and the value of the ordinary symbol random number are extracted. The extracted success / failure random value is compared with the success / failure determination value “1” at the normal probability, and the success / failure determination values “1”, “3”, “5”, “7”, “9”, and “11” at the high probability. If it matches, a big hit will be generated, otherwise it will be missed. When a big hit occurs, the extracted big hit symbol random number value is incremented by 1 and this value is used as the identification number of the left, middle and right stationary symbol designation codes. That is, the identification numbers of the left, middle and right stationary symbol designation codes are the same. If they do not match and are out of place, left, middle, and right stationary symbols are specified by adding 1 to each of the random values for the left symbol, random value for middle symbol, and random value for right symbol of the extracted random symbol The code identification number. At this time, if the three identification numbers coincide with each other by chance, the value of the identification number of the right stationary symbol designation code is changed by a value “1”.

4). Big hit start The big hit start demo command code says that a big hit occurred after the left, middle and right special symbols displayed in the special symbol display areas 50a to 50c display the same symbol until the big hit operation starts. This command is used to display an image that appeals to the player, and is composed of an operation number of 40H and an identification number of 01H. When this command code is received by the image control board 33, characters such as “big hit” are displayed on the screen of the LCD 32a, and an image that the character is pleased with is displayed. Processing to output the illumination is performed.

5. Big hit Medium hit big hit commands are classified into five commands: pre-open code, open code, 10-count winning code, V pass code, and round display code.
(1) The pre-opening code is composed of an operation number of 50H and an identification number of 01H, and when the image control board 33 inputs this command code, an image that informs the player that the special winning opening 40 will be opened is displayed on the background screen. The process displayed on 52 is executed.
(2) The opening code is composed of an operation number of 50H and an identification number of 02H. When the image control board 33 inputs this command code, an image that informs the player that the special winning opening 40 is being opened is displayed. Execute the process to be displayed.
(3) The 10-count winning code is composed of an operation number of 50H and an identification number of 03H, and the game control board 30 detects that a game ball has entered the big winning opening 40 by the count switch 40b or the V switch 40a. This instruction code is transmitted every time. When the image control board 33 inputs this instruction code, the value is incremented every time it is input, and the value is displayed on the background screen 52. Thereby, on the screen, the number from zero to ten is displayed every time a game ball wins the big winning opening 40.

(4) The V pass code is composed of an operation number of 50H and an identification number of 04H. When the game control board 30 detects that the game ball has passed through a special area in the big prize opening 40, this command is issued. Send the code. When the image control board 33 inputs this command code, the character “V” is displayed large on the screen to inform the player that the special winning opening 40 is closed and then opened again.
(5) The round display code is composed of an operation number of 50H and an identification number of 05H, and the game control board 30 transmits this instruction code every time the special winning opening 40 is opened again after the opening operation is completed. When the image control board 33 inputs this instruction code, the value is incremented every time it is input, and the value is displayed on the background screen 52. As a result, the player is notified of the number of times the special winning opening 40 is opened.

6). Jackpot End The jackpot end command consists of a jackpot end demo command code and a high probability transition command code.
The jackpot end demo command code indicates that the game ball does not pass through the special area when the jackpot operation ends, that is, when the big winning opening 40 ends the opening operation 16 times, or even if it does not continue until 16 times. The instruction code is transmitted when the operation is performed, and is composed of an operation number of 60H and an identification number of 01H. When the image control board 33 inputs this command code, a message is displayed informing the player that the big hit has ended.
The high probability transition command code is composed of an operation number of 61H and identification numbers of 01H to 02H. When the identification number is 01H, the transition is made to the high probability state after the end of the jackpot, and when the identification number is 02H, the transition is not made to the high probability state. The high probability transition command code may be transmitted from the game control board 30 to the image control board 33, or may be determined by the image control board 33 from the value of the image display command described above.

7). When abnormal operation The abnormal operation command is an instruction command transmitted when an abnormality occurs in the pachinko machine 10, and in this embodiment, from the E1 error code of 70H01H, the E2 error code of 70H02H, and the E3 error code of 70H03H It is configured. In the present embodiment, the E1 error code is output when a ten-count abnormal error is detected and no game ball is detected when the special winning opening 40 is opened, and the E2 error code is full when the lower plate 23 is full. 43 is output when the switch is turned on, and the E3 error code is output when the supply switch 44 is turned on. The error message displayed by sending these abnormal time commands is deleted by the error release code of 70H04H that is sent when the abnormality is released.

Next, a process for variably displaying special symbols on the screen of the LCD 32a using the above-described command code will be described with reference to FIGS.
Here, first, the process of determining (selecting) the basic variation pattern will be described with reference to FIGS. 15 and 16.
The microcomputer of the game control board 30 reads the determination result in step S180 of the main routine (step S300 in FIG. 15), reads the presence / absence of reach (step S310), reads the presence / absence of time reduction (step S320), and displays a stationary symbol. Read (step S330).
The presence / absence of reach is determined by whether or not the left stationary symbol and the middle stationary symbol match even when an out symbol is displayed. When the random number extracted using the reach random number is a predetermined value, the reach is determined. It is good also as a structure which determines whether display is performed.
Time reduction means shortening the fluctuation time of the left, middle, and right special symbols that are variably displayed in the special symbol display areas 50a to 50c in the above-described high probability state as compared with the normal state. As described above, when the probability is high, the opening time of the entrance of the ordinary electric accessory 36 is extended, and the number of determination results of the ordinary symbol is further increased. As a result, when the probability is high, the number of winnings in the ordinary electric accessory 36 is increased, and the variation time of the special symbol is also shortened. It is possible to increase the derivation of the determination result of the hit special symbol.

By executing the processing of steps S300 to S330, when the determination result, the presence / absence of reach, the presence / absence of time reduction, and each stationary symbol are read, in the subsequent processing, the basic variation pattern is determined according to the read data. (Step S340), the process returns.
As shown in FIG. 16, when the process moves to the process of step S340 (STP1), the basic variation pattern is first divided into a big hit (STP2) or missed (STP3) depending on the result of the determination. In the case of detachment, it is further distributed to reach (STP4) or not reach (STP5).
When the jackpot (STP2), out-going (STP3) reach (STP4) or no reach (STP5) is sorted, each is sorted according to whether or not there is a short time (STP6 to STP11).

The jackpot (STP2) with short time (STP6) is further distributed according to whether the symbol is the specific symbol which is the high probability symbol (STP12 to STP13). Similarly, the jackpot (STP2) timelessness (STP7) is further sorted according to whether the symbol is the specific symbol that is the high probability symbol (STP14 to STP15).
Out of reach (STP3) with reach (STP4) and no shortage (STP9) are further divided into two (STP16 to STP17) depending on whether or not they are the symbols before and after the jackpot symbol. Here, the symbols before and after the jackpot mean that the right still symbol is close to the left and middle stationary symbols.

  STP12 is assigned the basic pattern 1 (STP18), STP13 is the basic pattern 2 (STP19), STP14 is the basic pattern 3 (STP20), STP15 is the basic pattern 4 (STP21), and STP8 is the basic pattern 5 that has been distributed by the above distribution process. (STP22) and STP16 correspond to the basic pattern 6 (STP23), STP17 corresponds to the basic pattern 7 (STP24), STP10 corresponds to the basic pattern 8 (STP25), and STP11 corresponds to the basic pattern 9 (STP26).

When the image display command including the basic variation pattern is transmitted from the game control board 30 to the image control board 33 via the first relay board 37a, the image control board 33 displays the “display pattern selection routine” shown in FIG. Execute.
When the CPU 33a of the image control board 33 determines that an image display command is transmitted from the game control board 30 (step S400), it reads the basic variation pattern and each stationary symbol from the command code (steps S410 to S420). The display pattern is sorted from the data (step S430), and the process returns to return. If no image display command is transmitted from the game control board 30 in step S400, the process returns. FIG. 18 is a schematic diagram showing a configuration in which each of the nine basic patterns of the basic variation pattern is distributed to two or more display patterns.

FIG. 19 specifically shows a configuration in which the basic variation patterns 1 to 9 including nine basic patterns are distributed to two or more display patterns. Each of the basic patterns 1 to 9 has a display pattern, and the variation time of the stop symbol (here, the right symbol) that stops last is set to be common (identical) within the same variation pattern. This same time is 10 seconds for variation pattern 1, 7 seconds for basic pattern 2, 30 seconds for basic pattern 3, 25 seconds for basic pattern 4, 8 seconds for basic pattern 5, 20 seconds for basic pattern 6, and basic pattern 7 Is 28 seconds, the basic pattern 8 is 7 seconds, and the basic pattern 9 is 15 seconds. These fluctuation times can be changed as appropriate. These fluctuation times can be changed as appropriate. In this embodiment, at the start of symbol variation, the left, middle, and right symbols start to vary simultaneously, and the symbols stop in the order of left, middle, and right. That is, the time from when the right symbol starts to change until the right symbol stops changing is one symbol change time.
The basic pattern 1 is when a special symbol of jackpot, ie, “111”, “333”, “555”, “777”, “999”, “BBB” or “DDD” is displayed and there is a short time It is. In this basic pattern 1, the time for the variable display on each special symbol display area 50a to 50c is the same as that on each display area when the static symbol of each special symbol determined according to the static symbol designation code is "1". After the change is started, the scroll change display is performed for 4 seconds on the display area 50a and the display is stopped at the symbol "1", the scroll change display is displayed on the display area 50b for 6 seconds and the display is stopped at the display "1". On 50c, it scrolls and displays for 10 seconds and stops at the symbol “1”.

When the stationary symbol of each special symbol is “D”, the variation starts simultaneously on each display area, then scrolls and changes for four seconds on the display region 50a, stops at the symbol “D”, and the display region 50b Above, the scroll change display is performed for 7 seconds and the symbol “D” is stopped. On the display area 50c, the scroll change is displayed for 10 seconds and the symbol “D” is stopped.
When the stationary symbol of each special symbol is “3”, the variation starts simultaneously on each display area, and then the scroll variation is displayed on the display region 50a for 5 seconds, the symbol “3” is stationary, and the display region 50b is displayed. On the top, the scroll change display is performed for 7 seconds and the symbol “3” is stopped. On the display area 50c, the scroll change is displayed for 10 seconds and the symbol “3” is stopped.

When the special symbol's stationary symbol is “7”, it starts to fluctuate on each display area at the same time, then changes in all rotations, that is, the scroll fluctuating display with the same three-digit symbol, and “7” is simultaneously displayed after 10 seconds. Stand still with the design.
That is, in the basic pattern 1, the variation start time and the variation time on the display region 50c are made the same, but the variation times on the display regions 50a and 50b are different depending on seven types of three-digit identical specific symbols. Is set. Thereby, the basic variation pattern 1 distributes the display pattern into seven types by seven types of static symbols.

  Basic pattern 2 is a jackpot non-specific symbol, that is, “000”, “222”, “444”, “666”, “888”, “AAA”, “CCC” or “EEE”. And there is a case where time is short. In this basic pattern 1, the time for the variable display on the special symbol display areas 50a to 50c is simultaneously changed on each display area when the static symbol of each special symbol determined according to the static symbol designation code is “0”. After the change is started, the scroll change display is performed for 4 seconds on the display area 50a and the display is stopped with the symbol “0”, the scroll display is changed for 5 seconds on the display area 50b, and the display area 50 is stopped. On 50c, it scrolls and displays for 7 seconds and stops at the symbol “0”.

When the stationary symbol of each special symbol is “E”, the variation starts simultaneously on each display area, then scrolls and changes for four seconds on the display region 50a, and stops at the symbol “E”. Above, the scroll change display is performed for 6 seconds and the symbol “E” is stopped. On the display area 50c, the scroll change is displayed for 7 seconds and the symbol “E” is stopped.
When the stationary symbol of each special symbol is “2”, the variation starts simultaneously on each display area, and then the scroll variation is displayed on the display region 50a for 5 seconds, the symbol “2” is stationary, and the display region 50b is displayed. On the top, the scroll change display is performed for 6 seconds and the symbol “2” is stopped. On the display area 50c, the scroll change is displayed for seven seconds and the symbol “2” is stopped.

When the stationary symbol of each special symbol is “8”, after the fluctuation starts simultaneously on each display area, the whole rotation variation, that is, the scroll variation is displayed with the same symbol of 3 digits, and “8” is simultaneously displayed after 7 seconds. Stand still with the design.
That is, in the basic pattern 2, the change time on the display areas 50a and 50b is made the same with the start time of change and the change time on the display area 50c by the eight types of non-specific symbols of the same three digits. It is set to be different. Thereby, the basic variation pattern 2 distributes the display patterns into 8 types by 8 types of static symbols.

  By the same processing as the basic patterns 1 and 2, the basic patterns 3 to 9 also have the same change start time and the change time on the display area 50c, but the difference between the still symbols and the display patterns 50a and 50b. Two or more display patterns can be distributed so as to vary the variation time.

The CPU 33a of the image control board 33 distributes the basic variation pattern transmitted from the game control board 30 to the display pattern, determines the display pattern, and the CPU 33b and the sound / lighting control board 34 determine the determined display pattern. To send to. The sound / lighting control board 34 stores sound data and lighting data corresponding to the received display pattern, and the sound / lighting control board 34 determines the contents of the received display pattern, and performs sound effects and electronic lighting. Sound effects and electrical decoration are output controlled at the timing when decoration should be output. This output control is sequentially executed as necessary by the sound effect control board 34 in accordance with the received display pattern.
The CPU 33b executes image control corresponding to the display pattern received from the CPU 33a. The CPU 33b displays the image according to the transmitted display pattern on the LCD 32a in a variable manner, and statically displays the static symbol instructed after the change time has elapsed. The display is confirmed at the timing when the stationary confirmation signal is received.

As described above, the CPU 33a may be configured to sequentially transmit control signals to the sound / lighting control board 34 according to the display pattern, instead of being configured to transmit the display pattern to the sound / lighting control board 34. .
That is, the sound / lighting control board 34 stores sound data and lighting data corresponding to the control signals sequentially transmitted from the image control board 33, and the CPU 33a transmits the selected display pattern to the CPU 33b. At a timing at which the content of the selected display pattern is judged and sound effects and electrical decorations are to be output, a control signal corresponding to the sound effects and electrical decorations is transmitted to the sound and electrical control board 34. The transmission of the control signal to the sound / lighting control board 34 is sequentially executed as necessary during the symbol variation time period. When the sound / electrical decoration control board 34 receives the transmitted control signal, the sound / electrical decoration control board 34 controls the output of the sound effect and the electric decoration corresponding to the control signal. The CPU 33b executes image control in accordance with the received display pattern type. For example, according to the content of the determined display pattern, the CPU 33a instructs to output a sound effect when the left stop symbol, middle stop symbol and right stop symbol are stopped, or outputs a sound effect when the character appears. It is possible to give instructions. The same applies to the illumination.

The sound / lighting control board 34 is mainly composed of a driving element such as a transistor. Upon receiving a command from the image control board 33, the speaker 46, the lamps 60 such as a jackpot lamp and an error lamp, and the LED 61 are turned on. Display. That is, as shown in FIG. 20, the sound / lighting control board 34 stores sound data and lighting data corresponding to each display pattern, and the sound / lighting control board 34 receives the display pattern received from the CPU 33a. Sound effects and lighting control according to the sound data and lighting data corresponding to the type are performed.
On the other hand, a control signal is output from the sound / lighting control board 34 to the image control board 33.

  According to the first embodiment described in detail above, in the connection between the image control board 33 and the game control board 30, the one-way communication circuit that does not transmit data from the first relay board 37a to the game control board 30 is provided. Since a one-way communication circuit that does not transmit data from the image control board 33 to the first relay board 37a is provided for the connection between the control board 33 and the first relay board 37a, a game is not provided in the connection before and after the first relay board 37a. Since the circuit configuration is such that data is transmitted only from the control board 30 to the image control board 33, the fraudulent acts are difficult to perform and the fraudulent acts are easily discovered. That is, in order to perform an illegal act from the image control board 33 to the game control board 30, it is necessary to perform an illegal action on the double one-way communication circuit, and the first relay board 37a is equipped with a CPU. This is because a fraudulent act directly from the first relay board 37a is likely to be detected because it is a non-performing board.

  Further, in connection between the prize ball control board 31 and the frame lamp control board 35, a one-way communication circuit that does not transmit data from the second relay board 37b to the prize ball control board 31 is provided. Since the one-way communication circuit that does not transmit data from the frame lamp control board 35 to the second relay board 37b is provided for connection with the second relay board 37b, the winning ball control board 31 is used for connection before and after the second relay board 37b. Since the circuit configuration transmits data only to the frame lamp control board 35, the fraudulent act is difficult to perform, and the fraudulent act is easily found. In other words, in order to perform an illegal act from the frame lamp control board 35 to the winning ball control board 31, it is necessary to perform an illegal action on the double one-way communication circuit, and the second relay board 37b has a CPU. This is because a fraudulent act directly from the second relay board 37b is likely to be detected because the board is not mounted.

  The frame lamp control board 35 controls the lamp of the launch control board 49 and is connected to the prize ball control board 30 via the second relay board 37b, so that the payout detected by the prize ball control board 30 is detected. Notification of an abnormality or the like can be notified by the frame lamp control board 35.

  In addition, the launch control board 49 and the frame lamp control board 35 are bi-directionally communicated while being configured to prevent fraud by the double one-way communication circuit, and the frame lamp control and the launch control are completely synchronized. The frame lamp control and the launch control are closely associated with each other.

In addition, data can be bidirectionally communicated from the image control board 33 to the sound / lighting control board 34. When the image control board 33 receives data on the fluctuation pattern from the game control board 30, the fluctuation time of the received fluctuation pattern is received. Select one display pattern from a number of display patterns with the same variable display contents, and display a special symbol according to the selected display pattern. To do. Further, the image control board 33 transmits a control signal to the selected display pattern or to the sound / lighting control board 34, and the sound / lighting control board 34 has a sound effect according to the received display pattern or according to the control signal. And the output control of lighting is performed. Thereby, the display content of the image control board 33 can be matched with the sound effect and the electrical decoration of the sound / electrical decoration control board 34 without increasing the processing load of the game control board 30.
Further, if the image control board 33 is configured to transmit data indicating the type of display pattern to the sound / lighting control board 34, it is necessary to sequentially transmit signals in order to achieve consistency with sound effects. Disappear.

  The image control board 33 includes two CPUs 33a and 33b. The CPU 33a selects one display pattern from the received variation patterns, transmits the selected display pattern to the CPU 33b, and transmits the selected display pattern or control signal. Transmitted to the sound / lighting control board 34, the CPU 33b performs variable display according to the selected display pattern. As a result, the CPU 33b only needs to perform the process of executing the variable display according to the display pattern. Further, the CPU 33a selects the display pattern and transmits the selected display pattern or control signal to the sound / lighting control board 34 and the CPU 33b. Since it is only necessary to perform the process of transmitting data to, it is possible to distribute the processes by providing two CPUs.

  Since the image control board 33 simply selects the display pattern and transmits data indicating the type of the selected display pattern to the sound / lighting control board 34 and the CPU 33b, the processing load can be reduced.

  Since the communication between the image control board 33 and the sound / lighting control board 34 is bidirectional, the reliability of the communication can be improved, and the consistency between the display contents, the sound effect, and the lighting is further improved. Can do. Although the image control board 33 and the sound / lighting control board 34 are bidirectionally communicated with each other, the image control board 33, the sound / lighting control board 34, and the image / control board 33 are one-way communications that are transmitted only from the game control board 30. An illegal signal cannot be transmitted from the illumination control board 34 to the game control board 30. Therefore, it is effective for display contents, sound effects, consistency of electrical decorations, and fraud prevention. Furthermore, certainty can be given to the delivery of signals.

  Since the game control board 30 and the prize ball control board 31 are two-way communication, the payout of the prize ball has only to be executed by the prize ball control board 31 or the game control board 30, and the wiring can be simplified. Data such as the number of unpaid winning balls can be shared, and unpaid prize balls can be paid out after recovery from the power failure even if the power failure countermeasure is executed only by the game control board 30. This eliminates the need for power failure countermeasures on the prize ball control board 31 side. Here, since the two-way communication is used, unauthorized modification of the prize ball control board 31 becomes a problem. However, since the prize ball control board 31 is a board related to game performance, it often has a security function. If security functions are installed on both the game control board 30 and the prize ball control board 31, the fear of unauthorized modification is reduced, and furthermore, both boards are enclosed in so-called “caulking boxes” so that further countermeasures against fraud can be taken. I can plan.

  Since the sound / electrical decoration control board 34 and the game control board 30 cannot be directly communicated with each other, the sound / electrical decoration control board 34 can transmit commands and data via the image control board 33, and Since the game control board 30 and the image control board 33 are configured as one-way communication that is transmitted only from the game control board 30 via the first relay board 37a, the wiring to the game control board 30 is reduced, This has the effect of making it impossible to output an illegal signal to the game control board 30 from the image control board 33 or the sound / lighting control board 34.

  The game control board 30 stores and holds the game progress status and unpaid prize balls even in the event of a power failure. After the power failure is restored, the game control board 30 continues the game before the power failure and pays out the unpaid prize balls according to the stored data. Since the ball control board 31 is instructed, the game control board 30 stores and holds the game progress status and unpaid prize balls, so that the prize ball control board 31 does not need to take measures against power failure and further reduces the number of parts. It is possible to simplify the wiring and the ball game machine.

In the same basic pattern, the fluctuations on the display areas 50a and 50b are made while keeping the same fluctuation time from the start of the fluctuation of the special symbols on the special symbol display areas 50a to 50c until all the special symbols are stationary. The time can be assigned to two or more display patterns having different fluctuation times corresponding to the stationary symbols. As a result, while reducing the number of basic variation patterns created on the game control board 30 and reducing the processing load, the number of display patterns on which the special symbol varies on the screen of the LCD 32a is increased, and various special symbol display modes are provided. It has an extremely excellent effect that it can be changed in various ways.
Also, display patterns belonging to the same basic pattern have the same time from the start of special symbol change until the special symbol is confirmed, so when checking the performance of the machine with the concept of special symbol change time, the number of basic change patterns This has the effect of shortening the test time. The CPU 33a of the image control board 33 selects a display pattern from one of the basic patterns 1 to 9, and outputs data indicating the selected display pattern to the sound / lighting control board 34, or the sound / lighting according to the display pattern. Since the control board 34 is instructed to output sound effects, the display and sound effects can be matched.

Next, specific example 2 will be described with reference to FIGS.
In the second specific example, the “display pattern selection routine” shown in FIG. 21 is used instead of the “display pattern selection routine” shown in FIG. 17 used in the first embodiment, and the chart of FIG. 22 is used instead of the chart of FIG. The other configurations are substantially the same as those of the first embodiment.
In specific example 2, when the image display command is transmitted from the game control board 30 (step S500), the CPU 33a reads the basic variation pattern (step S510), and then extracts the value of the distribution random number FRND ( In step S520), display patterns are sorted from the extracted random number values (step S530), and the process returns to return. If no image display command is transmitted from the game control board 30 in step S500, the process returns. The distributed random number FRND is incremented by 1 every minute time, and when it reaches the maximum value “99”, it is configured as a counter that returns to “0” next time and repeatedly creates 100 integers from “0” to “99”. The value is extracted when the processing executed by the microcomputer of the image control board 33 shifts to this processing. The timing at which the image display command is transmitted from the game control board 30 is a timing that cannot be predicted in relation to the timing at which the game ball wins the ordinary electric accessory 36. Therefore, the distribution random number FRND that is a counter literally functions as a random number.

When the value of the sorting random number FRND is extracted, the CPU 33a selects a display pattern according to the chart shown in FIG. The CPU 33b displays an image on the LCD 32a in accordance with the selected display pattern.
If the display patterns shown in FIG. 22 belong to the same basic pattern, the change time from the start of change until all special symbols are determined is the same, but the change display on the display areas 50a and 50c is different. This distribution is performed according to the value of the extracted distribution random number FRND. At this time, if the value of the extracted sorting random number FRND is a predetermined value, a jackpot notice is made. The jackpot notice is a notice in advance that the jackpot symbol is displayed before the special symbol is confirmed with the same three digits. This jackpot notice is executed with a certain probability even if it is off. It is also possible to configure the reach notice to be executed based on the value of the random number FRND. The reach notice means that a notice in advance is reached that the symbol in the display area 50b is in a reach state before it is fixed and fixed. This reach notice is also performed with a certain probability even when the reach is not actually reached.

  As in the first embodiment, the sound / lighting control board 34 performs sound effects and lighting control according to the sound data and the lighting data corresponding to the type of display pattern received from the CPU 33a. At this time, if there is jackpot notice data, the data is transmitted from the CPU 33a, so it is possible to output sound by sound data corresponding to the jackpot notice. In addition, a similar sound can be output for the reach notice. The same applies to the illumination output.

  In the second specific example, the display pattern is distributed according to the value of the random number FRND. Thereby, in addition to the same effects as those of the first embodiment, the consistency between the image display and the sound output for the jackpot notice or the reach notice is enhanced. In addition, the display pattern is not fixed by the static symbol, and the display pattern can be made different even if the display modes of the three static symbols are the same. Further, it has an effect that the image control board 33 can instruct and execute the jackpot notice and the reach notice according to the value of the random number FRND.

  Next, a pachinko machine according to Embodiment 2 will be described with reference to FIG. In the first embodiment, the first relay board 37a and the second relay board 37b are provided (see FIG. 9). In the second embodiment, the first relay boards 137a and 137b are combined into one relay board 137. In addition to the effects similar to those of the first embodiment, the internal structure of the ball game machine can be saved. The frame lamp control board 35 and the launch control board 49 are configured as one board (launch control board 149), and the frame lamp control board 35 is not shown. The lighting control on the main body frame side may be performed by the sound / lighting control board 34 that performs the lighting control on the game board surface.

  Next, a pachinko machine according to Embodiment 3 will be described with reference to FIG. In the third embodiment, as in the second embodiment, the game control board 230 and the image control board 233 are connected by a double one-way communication circuit via the relay board 237, and the launch control board 249 The game control board 230 is connected via the relay board 237, and includes a one-way communication circuit that does not transmit data from the launch control board 249 to the relay board 237 for connection between the launch control board 249 and the relay board 237. Further, a one-way communication circuit for transmitting data from the launch control board 249 to the sound / lighting control board 234 is provided. The prize ball control board 231 and the relay board 237 are not connected. In addition to the effects of the first and second embodiments, the sound control panel 234 or the image control board 333 can notify the abnormality of the launch control board 249 and the like. In addition, illegal acts on the game control board 230 can be prevented via the launch control board. Other configurations are the same as those of the second embodiment. In FIG. 24, the corresponding part numbers are assumed to be in the 200s, and the description uses the first and second embodiments, and the other common elements are also described and illustrated by the first and second embodiments.

  In the third embodiment, the game control board 230 and the image control board 233 are connected via the relay board 237. However, instead of the image control board 233, the sound / lighting control board 234 is used. May be connected.

  Next, a pachinko machine according to Embodiment 4 will be described with reference to FIG. In the fourth embodiment, the launch control board 349 is directly connected to the relay board 337, the sound / lighting control board 334, and the image control board 333 as shown in the figure. It has not been. Further, an effect switch 338 for changing an image displayed on the LCD 332a is provided, and the image control board 333 is configured to detect an operation state by the effect switch 338. Since the image control board 333 and the sound / lighting control board 334 are configured to communicate with each other, the sound / lighting control board 334 can also detect the operation state of the effect switch 338. According to the fourth embodiment, since the sound / lighting control board 334 or the image control board 333 detects the operation state of the effect switch 338, it is possible to prevent an illegal act from the effect switch 338 in advance. be able to.
