Abstract

<P>PROBLEM TO BE SOLVED: To provide a control device of a game machine, capable of relieving a load for controlling variation displays through a main control board. <P>SOLUTION: The variation displays of the whole patterns 3a1-3c3 are started when each of variation pattern indicating commands 31 is sent from the main board to a display control board. In the duration of a high-speed variation, a stop pattern indicating command 32 is sent to each of display regions 3a1-3c3 in turn. A pattern in the high-speed variation is changed by the display board for adjusting itself to the stop pattern indicated by the command 32. After the variation displays continue on the variation patterns indicated by the command 31, the whole patterns are settled at once by a pattern stop command 33 being sent from the main board at the timing of the finish of the variation displays to finish a series of the variation displays. Thereby, the main board is not required for sending any command to the display board at each point in which the variation display turns, reducing the load for controlling the variation displays. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a control device for a gaming machine typified by a pachinko machine and the like, and more particularly to a control device for a gaming machine that can reduce the control burden of variable display by a main control board.

  The main control board that controls pachinko machine games includes a payout control board that controls the payout of prize balls and rental balls, a sound effect control board that controls the output of sound effects, and display controls such as symbol variation display. A display control board to be performed is connected. Among these boards, the control of the display control board is performed by a control command transmitted from the main control board to the display control board. This control command is subdivided so that the same variable part can be controlled by the same control command.

  When a display device that displays a variable pattern is composed of three lines, an upper stage, a middle stage, and a lower stage, and the variable display is performed while scrolling horizontally from right to left for each of the three lines, for example, FIG. As shown in FIG. 16, control commands (1) to (10) are transmitted from the main control board to the display control board, and a series of symbol variation display is performed.

  First, in accordance with the control command (1), the variable display of symbols is started for all three rows of the upper, middle and lower rows. Next, symbol replacement is performed for the upper symbol by the control command (2), for the middle symbol by the control command (3), and for the lower symbol by the control command (4). The control display (5) decelerates the display of all three lines that have been changed at high speed, and the control command (6) repeatedly changes the display in the upper and lower rows back and forth. The middle fluctuation display is the medium speed fluctuation. Furthermore, the control display (7) causes the change display in the middle stage to become low speed change again, and then the control display command (8) stops the change display in the upper stage, and the control command (9) displays the change display in the lower stage. It is stopped and the change display in the middle stage is stopped by the control command (10). As a result, all three rows of variable display are stopped, and a series of variable displays are terminated.

  Since the control command for controlling the variation display is transmitted from the main control board to the display control board at each point where the state of the variation display changes, most control of the variation display is performed by the main control board. It will be. For this reason, the control burden on the main control board becomes large, which interferes with other controls executed on the main control board, or a program for the main control board with limited capacity for control of variable display. There has been a problem in that it is difficult to develop the program of the main control board by increasing the capacity and the data capacity.

  The present invention has been made in order to solve the above-described problems, and reduces the control burden of variable display by the main control board and reduces the program capacity and data capacity mounted on the main control board to perform main control. An object of the present invention is to provide a control device for a gaming machine that can facilitate the development of a board program.

In order to achieve this object, a control device for a gaming machine according to claim 1 includes a display device for displaying symbols, a main control board for controlling a game, and a control command transmitted from the main control board. And a control board for display that causes the display device to display a variation of the symbol, and the control command transmitted from the main control substrate is a variation pattern designation that designates a series of variation patterns of the variation display. The command and at least a stop symbol designation command for designating a stop symbol to be stopped and displayed on the display device at the end of the variable display.
According to the control device for a gaming machine according to claim 1, a series of variation patterns of variation display performed on the display device is designated by the variation pattern designation command of the control command transmitted from the main control board, and The stop symbol to be stopped and displayed on the display device at the end of the variable display is specified by the stop symbol specifying command of the control command transmitted from the main control board. Based on the designation by these control commands, the display control board performs variable display of symbols.

According to the gaming machine control device of the present invention, a series of variation patterns can be designated at once by a variation pattern designation command, so that a control command is issued from the main control board for each point at which the variation display state changes. There is no need to send. Therefore, the control load of the variable display by the main control board can be reduced, and the program development of the main control board can be reduced by reducing the program capacity and data capacity mounted on the main control board for the control of the variable display. There is an effect that it can be made easy.
In addition, by changing the control of the fluctuation display on the side of the board (for example, the sub board or the display control board) that receives the fluctuation pattern designation command and controls the fluctuation display corresponding to the fluctuation pattern designation command, The contents (pattern) of the variable display can be changed while the control of the main control board is left as it is. Therefore, it is possible to cause the display device to perform different variable displays simply by replacing the sub-board connected to the main control board and the display control board while sharing the main control board (program thereof). is there.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this embodiment, a pachinko machine that is a kind of a ball game machine, in particular, a first type pachinko game machine will be described as an example of the game machine. Note that it is naturally possible to use the present invention for the third kind pachinko gaming machine and other gaming machines.

  FIG. 1 is a front view of a game board of the pachinko machine P according to the first embodiment. Around the game board 1, there are provided a plurality of winning holes 2 through which 5 to 15 balls are paid out when a hit ball is won. In the center of the game board 1, a liquid crystal (LCD) display 3 for displaying symbols as a plurality of types of identification information is provided. The display screen of the LCD display 3 is divided into three in the horizontal direction. In each of the three divided display areas, the symbols are displayed in a variable manner while scrolling from right to left in the horizontal direction.

  Below the LCD display 3, a symbol operating port (first type starting port) 4 is provided. When the hit ball passes through the symbol operating port 4, the above-described variation display of the LCD display 3 is started. Below the symbol operating port 4, a specific winning port (large winning port) 5 is provided. The specific winning opening 5 is a big hit when the display result after the fluctuation of the LCD display 3 coincides with one of the predetermined symbol combinations, so that the hitting ball is easy to win for a predetermined time (for example, 30 It is a winning opening that is opened (until the second elapses or 10 hitting balls are won). A V zone 5a is provided in the specific winning opening 5, and when the hit ball passes through the V zone 5a while the specific winning opening 5 is opened, a continuation right is established and the specific winning opening 5 is closed. Thereafter, the specific winning opening 5 is opened again for a predetermined time (or until a predetermined number of hit balls win the specific winning opening 5). The opening / closing operation of the specific winning opening 5 can be repeated up to 16 times (16 rounds), and the state in which the opening / closing operation can be performed is a state in which a predetermined game value is given (special game state). is there.

  FIG. 2 is a block diagram showing an electrical configuration of the pachinko machine P. As shown in FIG. On the main control board C of the pachinko machine P, an MPU 11 that is an arithmetic unit, a ROM 12 that stores various control programs executed by the MPU 11 and fixed value data, and various types of data are temporarily stored. A RAM 13 as a memory is mounted. The programs of the flowcharts shown in FIGS. 7 and 8 are stored in the ROM 12 as a part of the control program.

  The RAM 13 includes a transmission buffer 13a and a command counter 13b. The transmission buffer 13 a is a buffer for storing a control command transmitted from the main control board C to the display control board D for controlling the variable display of the LCD display 3. Since the control command is composed of 2 bytes, the transmission buffer 13a is also composed of 2 bytes. The control command set (written) in the transmission buffer 13a is transmitted to the display control board D byte by byte by the timer interrupt process.

  FIG. 3 is a diagram showing a state in which the display screen of the LCD display 3 is divided into nine display areas. As described above, the variable display of the present embodiment is performed while scrolling in the horizontal direction in the direction of arrow A in each of the three display areas 3a, 3b, 3c divided into three in the horizontal direction. Three display areas 3a, 3b, 3c divided into three in the horizontal direction are further divided into three display areas 3a1,..., 3c3 in the vertical direction, and the nine display areas 3a1,. , 3c3, nine symbol numbers 32a of "symbol 1 to symbol 9" are attached as shown in FIG.

  The command counter 13b shown in FIG. 2 is a counter for indicating the display areas 3a1 to 3c3 of the LCD display 3 designated by the stop symbol designation command 32 (see FIG. 5) which is a kind of control command. "1" in the range of "". When the value of the command counter 13b is within the range of “1-9”, the display areas 3a1 to 3c3 of the symbol number 32a (see FIG. 5) corresponding to the value of the command counter 13b are designated. When the value of the command counter 13b is “10”, no display area is designated.

  As shown in FIG. 2, the MPU 11, ROM 12, and RAM 13 are connected to each other via a bus line 14, and the bus line 14 is also connected to an input / output port 15. The input / output port 15 is connected to the display control board D and other input / output devices 16. The main control board C sends various commands to the display control board D and other input / output devices 16 via the input / output port 15 to control these devices. The main control board C and the display control board D are connected via two buffers (inverter gates) 17 and 28 having fixed inputs and outputs. Therefore, transmission / reception of a control command between the main control board C and the display control board D is performed only in one direction from the main control board C to the display control board D, and the display control board D performs main control. A control command or the like cannot be transmitted to the substrate C.

  The display control board D includes an MPU 21, a program ROM 22, a work RAM 23, a video RAM 24, a character ROM 25, an image controller 26, an input port 29, and an output port 27. The output of the inverter gate 28 is connected to the input of the input port 29, and the output of the input port 29 is connected to a bus line connecting the MPU 21, the program ROM 22, and the work RAM 23. An image controller 26 is connected to the input of the output port 27, and the LCD display 3 is connected to the output of the output port 27.

  The MPU 21 of the display control board D is for controlling the (variation) display of the LCD display 3 based on the control command transmitted from the main control board C. The program ROM 22 is executed by the MPU 21. Various control programs to be executed are stored. The programs of the flowcharts shown in FIGS. 9 and 10 are stored in the program ROM 22 as part of the control program. The work RAM 23 is a memory that stores work data and flags used when the MPU 21 executes various programs. The work RAM 23 includes a reception buffer 23a, a command reception flag 23b, and nine stop symbols 1 to 9 memories 23c to 23k. I have.

  The reception buffer 23a is a buffer for receiving a control command transmitted from the main control board C. Since the control command is composed of 2 bytes, the reception buffer 23a is also composed of 2 bytes. The command reception flag 23b is a flag that is turned on when a new control command is stored in the reception buffer 23a. When the command reception flag 23b is turned on, the control command stored in the reception buffer 23a is read out, and the fluctuation display of the LCD display 3 is controlled based on the read out control command. The command reception flag 23b once turned on is turned off when a control command is read from the reception buffer 23a.

  The stop symbol 1-9 memories 23c-23k are memories for storing a stop symbol code 32b (see FIG. 5) transmitted by a stop symbol designation command 32 which is a kind of control command. A total of nine stop symbols 1 to 9 memories 23c to 23k are provided corresponding to the nine display areas 3a1 to 3c3 (see FIG. 3). The symbols that are displayed in a variable manner are calculated by the MPU 21 in consideration of the pattern of the variable display so that the variation display ends with the symbols stored in the stop symbols 1 to 9 memories 23c to 23k. Replaced inside. The details of the stop symbol 1-9 memories 23c-23k will be described later.

  The video RAM 24 is a memory in which display data to be displayed on the LCD display 3 is stored. By rewriting the contents of the video RAM 24, the display contents of the LCD display 3 are changed. That is, the variable display of symbols in the display areas 3a1 to 3c3 is performed by rewriting the contents of the video RAM 24. The character ROM 25 is a memory for storing character data such as symbols displayed on the LCD display 3. The image controller 26 adjusts the timing of each of the MPU 21, the video RAM 24, and the output port 27, intervenes in reading and writing data, and displays the display data stored in the video RAM 24 at a predetermined timing with reference to the character ROM 25. This is displayed on the display 3.

  Next, a control command transmitted from the main control board C to the display control board D for controlling the variable display will be described with reference to FIGS. The control command includes three types of commands: a variation pattern designation command 31, a stop symbol designation command 32, and a symbol stop command 33. Since the control command is composed of 2 bytes, the most significant bit is set in the 1st byte command code to distinguish the 1st byte from the 2nd byte command code. The most significant bit of the code is reset.

  FIG. 4 is a diagram showing the command code of the variation pattern designation command 31 and the command contents. The fluctuation pattern designation command 31 is a command for starting a fluctuation display and designating a series of fluctuation patterns from the start to the end of the fluctuation display. The command code of the first byte is C0H or C1H, and a total of 56 types of variation patterns are prepared.

  Note that the control of the variation display designated by the variation pattern designation command 31 is performed by the display control board D that has received the variation pattern designation command 31, so that the content of the control program of the display control board D is changed. Thus, the contents of the fluctuation display for the fluctuation pattern designation command 31 of the same code can be changed. That is, the contents of the variable display can be changed by changing the control program of the display control board D without changing the control program of the main control board C.

  FIG. 5A is a diagram showing the correspondence between the command code of the stop symbol designation command 32 and the symbol number 32a designated by the command code. As described above, each display area 3a1 to 3c3 shown in FIG. 3 is associated with each symbol number 32a. FIG. 5B is a diagram showing the correspondence between 20 types of symbol codes 32b and symbol names 32c.

  The stop symbol designation command 32 is a command for designating symbols to be stopped and displayed in the display areas 3a1 to 3c3 of the LCD display 3 at the end of the variation display of the variation pattern designated by the variation pattern designation command 31. . The stop symbol designation command 32 is transmitted from the main control board C to the display control board D for each of the nine display areas 3a1 to 3c3 of the LCD display 3 after the fluctuation pattern designation command 31 is transmitted and the fluctuation display is started. Sent to.

  This stop symbol designating command 32 is composed of 2 bytes, like the variation pattern designating command 31. In the first byte of the stop symbol designation command 32, a command code for designating the display areas 3a1 to 3c3 of symbols 1 to 9 is set. As shown in FIG. 5A, if the command code of the first byte of the stop symbol designation command 32 is “90H”, the display area 3a1 of symbol 1 is displayed. If “A0H”, the display area 3b1 of symbol 2 is displayed. ..., “B2H” designates the display area 3c3 of the symbol 9 respectively. In the second byte of the stop symbol designation command 32, the symbol code 32b of the symbol to be stopped and displayed in the display areas 3a1 to 3c3 of symbols 1 to 9 designated by the command code of the first byte is set. That is, as shown in FIG. 5B, “10H” is displayed when the symbol to be stopped is “octopus”, “11H” is displayed when “Harisenbon” is displayed,. In the case of (2), “23H” is set as the second byte code of the stop symbol designation command 32.

  When receiving the stop symbol designation command 32, the display control board D considers the variation pattern being executed, and ends the variation display with the symbol of the symbol code 32b designated by the stop symbol designation command 32. Replace the changing design. Since the symbol replacement is performed only when the fluctuation display is fluctuating at high speed, the player is not aware that the symbol replacement has been performed.

  As shown in FIG. 5B, a different symbol code 32b is assigned to each symbol. In particular, the symbol names 32c “shark (1)” and “shark (2)” are displayed on the LCD display 3 as exactly the same symbol, but as shown in FIG. ”And“ 23H ”are assigned different symbol codes 32b. Similarly, the symbol names 32c “shellfish (1)” to “shellfish (10)” are also displayed on the LCD display 3 as the same symbols, but as shown in FIG. 5B, “19H” to “22H”. The different symbol code 32b is given.

  Further, the variable display is divided into three display areas 3a, 3b, and 3c of the upper, middle, and lower stages of the LCD display 3 (see FIG. 3). This is done while scrolling horizontally on each stage. The arrangement (arrangement order) of symbols displayed on the virtual symbol reel is fixed. Therefore, even if a symbol is displayed as the same symbol on the LCD display 3, it is displayed before and after the symbol based on the symbol code 32b of the symbol by assigning the symbol symbol 32b which is different as described above. It is possible to calculate the symbol to be displayed.

  Accordingly, for each of the nine display areas 3a1 to 3c3, even if a part of the stop symbol designation command 32 transmitted from the main control board C to the display control board D is missing, each stage (upper / middle stage) In the lower part, if one or more stop symbol designation commands 32 can be normally received, the symbol code 32b of the missing stop symbol designation command 32 can be calculated. That is, by assigning different symbol codes 32b to all symbols and fixing the virtual symbol reel arrangement, a part of the stop symbol designation command 32 transmitted from the main control board C to the display control board D is partly displayed. Even if there is an omission, the symbol code 32b of the missing stop designating command 32 can be calculated, and normal variation display (and stop display at the end of variation display) can be performed.

  FIG. 6 is a diagram showing the command code of the symbol stop command 33 and the contents of the command. The symbol stop command 33 is a command for stopping and displaying (determining) a symbol that is variably displayed in the display areas 3a1 to 3c3 of the designated symbol number 32a. When the display control board D receives the symbol stop command 33, the stop symbols already specified by the stop symbol specifying command 32 are stopped and displayed in the display areas 3a1 to 3c3 specified by the symbol stop command 33. The symbols 3a1 to 3c3 are fixed. That is, the variable display of the display areas 3a1 to 3c3 designated by the symbol stop command 33 is finished. When the symbols of all nine display areas 3a1 to 3c3 are determined by the symbol stop command 33, the series of variation display started by the variation pattern designation command 31 is completed.

  The display control board D considers the contents of the variation pattern designation command 31 and the stop symbol designation command 32, and the display areas 3a1 to 3c3 corresponding to the symbols designated by the stop symbol designation command 32 at the timing of the variation display end. As shown in the above, symbols are replaced in advance during high-speed fluctuation of the fluctuation display. In addition, the main control board C controls to transmit the symbol stop command 33 to the display control board D at the timing when the fluctuation pattern of the fluctuation display designated by the fluctuation pattern designation command 31 ends. Therefore, the symbol stop display (decision) by the symbol stop command 33 is performed smoothly without giving the player a sense of incongruity.

  Note that, as a result of the transmission timing of the symbol stop command 33 from the main control board C being delayed, the symbol stop command 33 is received by the display control board D even though the variation pattern designated by the variation pattern designation command 31 is completed. If not, the display control board D continues the display in which the stop symbol designated by the stop symbol designation command 32 is moved back and forth within the corresponding display areas 3a1 to 3c3, so-called left and right display. To do. When the symbol stop command 33 is received from the main control board C, the stop symbol specified by the stop symbol specifying command 32 is stopped and displayed at the center of the corresponding display areas 3a1 to 3c3, and the symbols of the display areas 3a1 to 3c3 are displayed. Confirm (stop display).

  On the other hand, as a result of accelerating the transmission timing of the symbol stop command 33 from the main control board C, the display control board D performs the symbol stop command even though it is before the end of the variation pattern designated by the variation pattern designation command 31. When 33 is received, the display control board D stops the stop symbol already designated by the stop symbol designation command 32 in the center of the corresponding display areas 3a1 to 3c3 even before the end of the variation pattern. Display, and confirm the symbols of the display areas 3a1 to 3c3 (stop display).

  In the symbol stop command 33, nine types of commands for individually stopping and displaying (determining) the symbols of the nine display areas 3a1 to 3c3 and all nine symbols of the display areas 3a1 to 3c3 are stopped and displayed (determined) at a time. There are one type of command and three types of commands that individually stop and display (determine) the symbols of the three display areas 3a, 3b, and 3c divided into the upper, middle, and lower levels for each level. Thirteen types of commands are prepared. Of these, the symbol stop command 33 ((1) “80H, 0BH”, (2) for stopping and displaying (determining) three symbols at a time for each of the upper, middle, and lower levels as scroll units. If "80H, 0CH", (3) "80H, 0DH") is used, scrolling of the virtual symbol reel displayed on the display of the LCD display 3 by the control is performed in the same manner as actual symbol reel scrolling. And the interest of the player can be further improved.

  Next, each process executed by the pachinko machine P configured as described above will be described with reference to the flowcharts of FIGS. FIG. 7 is a flowchart of reset interrupt processing executed every 4 ms in the main control board C of the pachinko machine P. The main control of the pachinko machine P is executed by this reset interrupt process.

  In the reset interrupt process, first, a stack pointer is set (S1), and a pattern written in a predetermined area of the RAM 13 is checked (S2). If the predetermined pattern is written in the predetermined area as a result of the check, the RAM 13 is normal and normal (S2: normal), and the process proceeds to S3. On the other hand, if the predetermined pattern is not written in the predetermined area as a result of the check in S2, it is the reset interrupt process executed first after the power is turned on, or there is an abnormality in the RAM 13 (S2: abnormal) In this case, the process proceeds to S21, and once the contents of the RAM 13 are cleared, an initial value is written into the RAM 13 (S21), and the next reset interrupt process is awaited. Note that the initial value written in the RAM 13 in the process of S21 includes a predetermined pattern checked in the process of S2.

  In the process of S3, a timer interrupt is set (S3). Examples of the timer interrupt set here include a timer interrupt that generates a strobe signal for transmitting a control command for controlling the fluctuation display of the LCD display 3 to the display control board D. After setting the timer interrupt, each interrupt is permitted (S4). After the permission of the interrupt, the output data updated in the previous reset interrupt process by the special symbol variation process (S15), the display data creation process (S17), the ramp / information processing (S18), etc. A port output process for outputting to the port is executed (S5).

  Further, a random number update process (S6) for updating the value of the random number counter for determining the jackpot is performed by “+1”, and a storage timer subtraction process is executed (S7). The storage timer subtraction process shortens the time for symbol variation display when there are a predetermined number or more of reserve balls for jackpot determination and the symbol display is being varied on the LCD display 3.

  In the switch reading process (S8), the value of each switch is read, and the ball that has been driven into the game area 1 enters the winning port 2 and the big winning port 5 (including the V zone 5a) and passes through the symbol operating port 4. Further, it is a process for detecting a winning ball or a rental ball. The count abnormality monitoring process (S9) is a process for monitoring whether there is an abnormality in the switch data read by the switch reading process of S8. For example, even though the big winning opening 5 is opened and a hit ball is detected by the V count switch that detects the passing of the hit ball through the V zone 5a, the winning in the big winning openings 5 other than the V zone 5a is detected 10 If a single shot cannot be detected by the count switch, some abnormality has occurred in the 10 count switch, for example, by removing the 10 count switch. Further, when a single prize ball is not paid out even though the motor for paying out a prize ball is driven, some abnormality has occurred in the prize ball payout device. As described above, in the count abnormality monitoring process (S9), the presence / absence of the abnormality as described above is monitored based on the switch data read by the switch reading process (S8).

  In the symbol counter update process (S10), a counter update process for determining a symbol to be stopped and displayed as a result of the variable display performed on the LCD display 3 is performed. In the symbol check process (S11), based on the counter value updated in the symbol counter update process (S10), the jackpot symbol, the off symbol, and the reach symbol used in the special symbol variation process (S15). Etc. are determined.

  If no error has occurred in the processing from S3 to S11 (S12: normal), the normal symbol variation processing (S13) displays the variation of the 7-segment LED (not shown) and the result of the variation display. When a hit occurs, a hit process for opening a normal electric accessory (not shown) for a predetermined time is executed. After that, the state flag is checked (S14), and if the symbol change is started or displayed on the LCD display 3 (S14: symbol changing), the ball hits the symbol operating port 4 by the special symbol changing process (S15). Based on the value of the random number counter read at the passing timing, it is determined whether or not the game is a big hit, and a symbol variation process is executed on the LCD display 3. On the other hand, if the result of checking the status flag is a big hit (S14: big hit), a big hit process (S16) such as opening the big prize opening 5 is executed. Further, as a result of checking the status flag, if the symbol is not changing or big hit (S14: Other), the processing of S15 and S16 is skipped and the process proceeds to the display data creation processing of S17. If an error is confirmed in the process of S12 (S12: error), each process of S13 to S16 is skipped and the process proceeds to a display data creation process of S17.

  In the display data creation process (S17), demo data displayed on the LCD display 3, display data of the 7 segment LED, and the like are created in addition to the symbol variation display. In the lamp / information processing (S18), the lamp of the holding ball is displayed. Various lamp data including data are created. In the sound effect process (S19), sound effect data corresponding to the game situation is created. These display data and sound effect data are output to each device by the port output process (S5) and the timer interrupt process described above.

  After the sound effect process (S19) ends, the symbol counter update process (S20), which is the same process as S10, is repeatedly executed for the remaining time until the next reset interrupt process occurs. Since the execution time of each process of S1-S19 changes according to the state of a game, the remaining time until the next reset interruption process generate | occur | produces is not a fixed time. Therefore, by repeatedly executing the symbol counter update process (S20) using the remaining time, the stop symbol can be changed at random.

  FIG. 8 is a flowchart showing a command setting process executed in the special symbol variation process (S15) of the reset interrupt process in FIG. In this command setting process, a variation pattern designation command 31, a stop symbol designation command 32, and a symbol stop command 33, which are control commands for controlling variation display on the LCD display 3, are transmitted from the main control board C to the display control board D. This is a process for writing (setting) the commands 31 to 33 to the transmission buffer 13a.

  In the command setting process, first, the state of variation display is checked by the state check flag (S31). As a result of the check, if variation display is started (S31: variation start), the variation pattern designation command 31 is written to the transmission buffer 13a (S32), the value of the command counter 13b is set to “1” (S33), and this processing is performed. finish. As described above, the variation pattern designation command 31 written to the transmission buffer 13a is transmitted to the display control board D byte by byte by the timer interrupt process set in the process of S3.

  In the process of S31, as a result of checking the state flag, if the symbol variation is being displayed (S31: during variation display), it is checked whether the value of the command counter 13b is equal to or less than “9” (S34). If the value of the command counter 13b is equal to or less than “9” (S34: Yes), the first byte of the stop symbol designation command 32 corresponding to the value of the command counter 13b is written to the upper byte of the transmission buffer 13a (S35). Based on the correspondence shown in FIG. 5A, for example, if the value of the command counter 13b is “1”, “90H” is obtained, and if the value of the command counter 13b is “2”, “A0H” is obtained. If the value of the command counter 13b is “9”, “B2H” is written to the upper byte of the transmission buffer 13a.

  Further, the symbol code 32b of the stop symbol corresponding to the value of the command counter 13b is written to the lower byte of the transmission buffer 13a (S36). For example, if the value of the command counter 13b is “1”, the symbol code 32b of the symbol that is stopped and displayed in the display area of the symbol 1 (3a1), and if the value of the command counter 13b is “2”, the symbol 2 (3b1) ) The symbol code 32b of the symbol that is stopped and displayed in the display area of..., And if the value of the command counter 13b is “9”, the symbol code 32b of the symbol that is stopped and displayed in the display area of symbol 9 (3c3) Are written to the lower byte of the transmission buffer 13a based on the correspondence shown in FIG. Here, when the symbol “octopus” is designated as the stop symbol, the symbol code 32b of “10H” is designated, and when the symbol “Harisenbon” is designated, the symbol code 32b of “11H” is ... When the symbol “shark (2)” is designated, the symbol code 32b “23H” is designated.

  After the 2-byte stop symbol designation command 32 is written to the transmission buffer 13a by the processing of S35 and S36, the value of the command counter 13b is incremented by “1” (S37), and this processing is terminated. The stop symbol designation command 32 written to the transmission buffer 13a is transmitted byte by byte to the display control board D by the timer interruption process set in the process of S3, as in the case of the variation pattern designation command 31. Is done.

  On the other hand, if the value of the command counter 13b is “10” or more (S34: No), this means that the stop symbol designation command 32 has been transmitted for all nine display areas 3a1 to 3c3. Therefore, in such a case, each process of S35 to S37 is skipped, and this process is terminated.

  In the processing of S31, if the status flag is checked and the timing of the end of the variable display is reached (S31: end of the variable display), the symbol stop that stops and displays (determines) all symbols in the nine display areas 3a1 to 3c3 at a time. The command 33 (80H, 0AH) is written to the transmission buffer 13a (S38), and this process is terminated. The symbol stop command 33 written to the transmission buffer 13a is transmitted to the display control board D byte by byte by the timer interrupt process set in the process of S3, as in the case of the variation pattern designation command 31. By transmitting the symbol stop command 33 to the display control board D, a series of variation display started by the variation pattern designation command 31 is completed.

  Note that the symbol stop display (decision) by the symbol stop command 33 does not necessarily require all nine symbols to be confirmed at one time. For example, nine symbols can be confirmed separately or scrolling can be performed. The symbol may be determined for each unit, ie, the upper symbol, the middle symbol, and the lower symbol. In the former case, as shown in FIG. 6, a symbol stop command 33 of “80H, 01H” to “80H, 09H” is used, and in the latter case, symbols of “80H, 0BH” to “80H, 0DH” are used. A stop command 33 is used.

  FIG. 9 is a flowchart of command reception processing executed in the reception interrupt processing of the display control board D. This command reception process is executed when a control command is transmitted from the main control board C to the display control board D. First, the control command transmitted from the main control board C and received by the display control board D is written into the reception buffer 23a (S41), and the command reception flag 23b is turned on (S42), and a new control command is received. This process ends after indicating that it is stored in the reception buffer 23a.

  FIG. 10 is a flowchart of the variable display process executed in the main process of the display control board D. In the fluctuation display process, the fluctuation display is controlled based on the control command received from the main control board C.

  First, it is confirmed whether or not the command reception flag 23b is turned on (S51). If the command reception flag 23b is turned on (S51: Yes), after turning it off (S52), the type of control command is confirmed based on the data stored in the upper byte of the reception buffer 23a (S53). If the upper byte of the control command stored in the reception buffer 23 a is “C0H” or “C1H”, the control command is the variation pattern designation command 31. Therefore, in such a case (S53: variation pattern designation command), variation display corresponding to the variation pattern designation command 31 is started on the LCD display 3 (S54).

  On the other hand, in the process of S53, if the upper byte of the control command stored in the reception buffer 23a is any one of “90H to 92H”, “A0H to A2H”, or “B0H to B2H”, the control command is This is a stop symbol designation command 32. Therefore, in such a case (S53: stop symbol designation command), the symbol code 32b which is the second byte command of the stop symbol designation command 32 is written to the corresponding stop symbol 1-9 memories 23c-23k (S55). As shown in FIGS. 5A and 5B, for example, if the stop symbol designation command 32 stored in the reception buffer 23a is “90H, 14H”, the stop symbol 1 memory 23c corresponding to “90H” The symbol code 32b of “14H (shrimp symbol)” is written. If the stop symbol designation command 32 stored in the reception buffer 23a is “B2H, 21H”, the symbol code 32b of “21H (shell symbol)” is stored in the stop symbol 9 memory 23k corresponding to “B2H”. Written.

  Thereafter, the symbol code stored in the stop symbols 1 to 9 memories 23c to 23k in consideration of the variation pattern and the progress status of the variation pattern, the symbol being varied at high speed on the LCD display 3 The changing symbol is replaced so that the changing display ends with the symbol 32b (S56). For example, when “14H” is stored in the stop symbol 1 memory 23c, the symbol in the display area 3a1 of symbol 1 ends with the symbol “shrimp” that is the symbol code 32b of “14H”. Is replaced. Further, when “21H” is stored in the stop symbol 9 memory 23k, the symbol in the display area 3c3 of the symbol 9 ends with the symbol “shell” which is the symbol code 32b of “21H”. Is replaced.

  In the process of S53, if the upper byte of the control command stored in the reception buffer 23a is “80H”, the control command is the symbol stop command 33. Therefore, in such a case (S53: symbol stop command), the symbols of the display areas 3a1 to 3c3 of the symbol number 32a designated by the symbol stop command 33 are determined (S57), and correspond to the display areas 3a1 to 3c3. Stop displaying symbols. For example, if the symbol stop command 33 of “80H, 0AH” is stored in the reception buffer 23a, the symbols of all nine display areas 3a1 to 3c3 are determined at a time and stopped. If the symbol stop command 33 of “80H, 0CH” is stored in the reception buffer 23a, the three symbols 2, 5, and 8 displayed in the middle display area 3b are determined at a time and stopped.

  When the command reception flag 23b is turned off in the process of S51 (S51: No), or after executing the processes of S54, S56, and S57, the processes according to the state of the variable display are executed (S58). Thereafter, the variation display process is terminated.

  Next, with reference to the timing charts of FIGS. 11 and 12, the timing of the variable display based on the above description will be described. First, with reference to FIG. 11, the timing when all nine symbols are stopped and displayed (determined) at once will be described. When the variation pattern designation command 31 is transmitted from the main control board C to the display control board D, the variation display is started for all the symbols from symbol 1 (3a1) to symbol 9 (3c3). Following this variation pattern designation command 31, a stop symbol designation command 32 is sequentially transmitted to the nine display areas 3a1 to 3c3 during the high-speed variation. When the stop symbol designation command 32 is received by the display control board D, symbols are replaced during high-speed fluctuation in accordance with the stop symbol designated by the stop symbol designation command 32.

  Thereafter, the variation display designated by the variation pattern designation command 31 continues the variation display by the display control substrate D, and all nine symbols are transferred from the main control substrate C to the display control substrate D at the timing of the variation display end. The symbol stop command 33 (80H, 0AH (see FIG. 6)) for stopping and displaying (determining) at a time is transmitted. When the symbol stop command 33 is received by the display control board D, a series of variation display started by the variation pattern designation command 31 is completed. After the end of the variable display, the display of the stop symbol designated by the stop symbol designation command 32 stopped and displayed in each of the display areas 3a1 to 3c3 is switched to another display as a predetermined time elapses.

  Next, with reference to the timing chart of FIG. 12, the timing when nine symbols are stopped and displayed (determined) by three symbols in the order of upper, lower, and middle will be described. Until the stop symbol designation command 32 is transmitted, it is performed in the same manner as the timing in FIG. 11, and symbols are replaced during high-speed fluctuation.

  At the timing of the end of the variable display, a symbol stop command 33 is first transmitted from the main control board C to the display control board D to stop and display (determine) the symbols displayed in the upper display area 3a (80H, 0BH). (See FIG. 6)). When the symbol stop command 33 is received by the display control board D, the symbols 1, 4, and 7 in the upper stage are stopped and displayed (see FIG. 3). Next, a symbol stop command 33 for stopping (determining) the symbols displayed in the lower display area 3c is transmitted (80H, 0DH (see FIG. 6)), and the lower symbols 3, 6, and 9 are stopped and displayed. Confirm (see FIG. 3). Further, a symbol stop command 33 for stopping (determining) the symbols displayed in the middle display area 3b is transmitted (80H, 0CH (see FIG. 6)), and the symbols 2, 5, and 8 in the middle are stopped and confirmed. (See FIG. 3). With the above three symbol stop commands 33, a series of variation display started by the variation pattern designation command 31 is completed.

  In this way, the virtual symbol reel displayed on the display by the control is expressed like an actual symbol reel by stopping and displaying the symbols in the order of the upper, lower and middle in accordance with the scroll direction of the symbol. Can do. When the symbol scroll direction is the vertical direction, the symbol stop display (determination) is performed, for example, in the order of left, right, and middle.

  As described above, according to the pachinko machine P of the present embodiment, since a series of variation patterns can be designated at once by the variation pattern designation command 31, the main control is performed for each point at which the variation display state changes. There is no need to transmit a control command from the substrate C. Therefore, the control load of the variable display by the main control board C can be reduced, and the program capacity and data capacity mounted on the main control board C for the control of the variable display can be reduced, so that the main control board C Program development can be facilitated.

  Further, if the control of the variation display corresponding to the variation pattern designation command 31 is changed on the display control board D side, the variation pattern can be changed without changing the program of the main control board C. Therefore, different variable displays can be performed on the LCD display 3 by simply replacing the display control board D while making the main control board C common.

  Next, a second embodiment will be described with reference to FIGS. In the second embodiment, the “variation start command 30” is newly added to the control command, the variation display is started by the variation start command 30, and the variation pattern designation command 31 designates only the variation pattern of the variation display. It is configured to do. The variation start command 30 of the present embodiment is composed of “D0H, 01H”. Since the other parts are the same as those of the first embodiment, the same reference numerals are given to the same parts as those of the first embodiment, and the description thereof is omitted.

  FIG. 13 is a flowchart showing the command setting process of the second embodiment executed in the special symbol variation process (S15) of the reset interrupt process in FIG. In this command setting process, a variation start command 30, a variation pattern designation command 31, a stop symbol designation command 32, and a symbol stop command 33, which are control commands for controlling variation display on the LCD display 3, are displayed from the main control board C. This is a process for writing (setting) each of the commands 30 to 33 to the transmission buffer 13a for transmission to the control board D.

  In the command setting process, first, the state of the variable display is checked by the state check flag (S81). As a result of the check, if the fluctuation display is started (S81: fluctuation start), the fluctuation start command 30 is written in the transmission buffer 13a (S82), the value of the command counter 13b is set to "1" (S83), and this process is terminated. To do. The change start command 30 written to the transmission buffer 13a is transmitted to the display control board D byte by byte by the timer interrupt process set in the process of S3 of FIG.

  In the process of S81, as a result of checking the state flag, if the symbol variation is being displayed (S81: during variation display), it is checked whether or not the value of the command counter 13b is “9” or less (S84). If the value of the command counter 13b is equal to or smaller than “9” (S84: Yes), the first byte of the stop symbol designation command 32 corresponding to the value of the command counter 13b is written to the upper byte of the transmission buffer 13a (S85). The symbol code 32b of the stop symbol corresponding to the value of the command counter 13b is written to the lower byte of the transmission buffer 13a (S86), and the stop symbol designation command 32 to be transmitted to the display control board D is set. Thereafter, "1" is added to the value of the command counter 13b (S87), and this process is terminated.

  On the other hand, if the value of the command counter 13b is “10” (S84: No, S88: Yes), the transmission of the stop symbol designation command 32 is completed for all nine display areas 3a1 to 3c3. A variation pattern designation command 31 for designating a pattern is written to the transmission buffer 13a (S89), and this process is terminated. The stop symbol designation command 32 and the variation pattern designation command 31 written to the transmission buffer 13a are displayed one byte at a time by the timer interrupt processing set in the processing of S3, as in the case of the variation start command 30. To D. If the value of the command counter 13b is equal to or greater than “11” (S84: No, S88: No), the transmission of the stop symbol designation command 32 and the variation pattern designation command 31 has already been completed. It waits for the transmission of the control command until the final symbol determination timing (stop display timing) arrives.

  In the process of S81, as a result of checking the state flag, if it is the fixed timing of the upper three symbols 1, 4, 7 (3a) (S81: upper symbol fixed), the three symbols 1, 4, 7 are once The symbol stop command 33 (80H, 0BH) to stop display (confirm) is written to the transmission buffer 13a (S90), and this processing is terminated. Also, if the lower three symbols 3, 6 and 9 (3c) are determined (S81: lower symbol determined), the symbol stop command for stopping and displaying (determining) the three symbols 3, 6, and 9 at a time. 33 (80H, 0DH) is written to the transmission buffer 13a (S91), and this process is terminated. Furthermore, if it is the fixed timing of the three symbols 2, 5, 8 (3b) in the middle stage (S81: middle symbol confirmed), the symbol stop command for stopping and displaying (determining) the three symbols 2, 5, 8 at a time. 33 (80H, 0CH) is written to the transmission buffer 13a (S92), and this process is terminated.

  The symbol stop command 33 written to the transmission buffer 13a is transmitted byte by byte to the display control board D by the timer interrupt process set in the process of S3, as in the case of the change start command 30. By transmitting the third symbol stop command 33 to the display control board D, a series of variation display started by the variation start command 30 is completed. The symbol stop display (determined) by the symbol stop command 33 is to stop display (determine) all nine symbols at once, or to stop display (determine) each of the nine symbols separately. Also good.

  FIG. 14 is a flowchart of the variable display process of the second embodiment executed in the main process of the display control board D. In the fluctuation display process, the fluctuation display is controlled based on the control command received from the main control board C.

  In the process of S53, if the upper byte of the control command stored in the reception buffer 23a is “D0H”, the control command is the change start command 30. Therefore, in such a case (S53: Change start command), change display is started on the LCD display 3 (S94).

  In the process of S53, if the upper byte of the control command stored in the reception buffer 23a is any one of “90H to 92H”, “A0H to A2H” or “B0H to B2H”, the control command is a stop symbol. This is a designation command 32. Therefore, in such a case (S53: stop symbol designation command), the symbol code 32b which is the second byte command of the stop symbol designation command 32 is written into the corresponding stop symbol 1-9 memories 23c-23k (S95).

  In the process of S53, if the upper byte of the control command stored in the reception buffer 23a is “C0H” or “C1H”, the control command is the variation pattern designation command 31. Therefore, in such a case (S53: Fluctuation pattern designation command), the fluctuation display of the fluctuation pattern designated by the fluctuation pattern designation command 31 is written to each stop symbol 1-9 memory 23c-23k by the stop symbol designation command 32. The symbol that is changing at high speed is replaced so as to end with the symbol of the symbol code 32b (S96).

  In the process of S53, if the upper byte of the control command stored in the reception buffer 23a is “80H”, the control command is the symbol stop command 33. Therefore, in such a case (S53: symbol stop command), the symbols of the display areas 3a1 to 3c3 of the symbol number 32a designated by the symbol stop command 33 are determined (S97) and correspond to the display areas 3a1 to 3c3. Stop displaying symbols. When the symbols of all the display areas 3a1 to 3c3 are fixed, the variation display process is finished.

  Next, with reference to the timing chart of FIG. 15, the timing of the variable display of the second embodiment based on the above description will be described. When the change start command 30 is transmitted from the main control board C to the display control board D, the change display is started for all the symbols from symbol 1 (3a1) to symbol 9 (3c3). Subsequent to the variation start command 30, a stop symbol designation command 32 is sequentially transmitted to the nine display areas 3a1 to 3c3. Further, following the stop symbol designation command 32, a variation pattern designation command 31 is transmitted. When the variation pattern designation command 31 is received by the display control board D, the variation display of the variation pattern designated by the variation pattern designation command 31 ends with the stop symbol designated by the stop symbol designation command 32. The symbol is replaced during high-speed fluctuation. After the symbol replacement, the display control board D performs a variable display based on the variation pattern designated by the variation pattern designation command 31.

  At the timing of the end of the variable display, a symbol stop command 33 is first transmitted from the main control board C to the display control board D to stop and display (determine) the symbols displayed in the upper display area 3a (80H, 0BH (see FIG. 6)). When the symbol stop command 33 is received by the display control board D, the symbols 1, 4 and 7 in the upper stage are fixed and are stopped and displayed (see FIG. 3). Next, a symbol stop command 33 for stopping and displaying (determining) the symbols displayed in the lower display area 3c is transmitted (80H, 0DH (see FIG. 6)), and the lower symbols 3, 6, and 9 are determined. The display is stopped (see FIG. 3). Further, a symbol stop command 33 for stopping and displaying (determining) the symbols displayed in the middle display area 3b is transmitted (80H, 0CH (see FIG. 6)), and the middle symbols 2, 5, and 8 are confirmed and stopped. Is displayed (see FIG. 3).

  With the above three symbol stop commands 33, a series of variation display started by the variation start command 30 ends. After the end of the variable display, the display of the stop symbol designated by the stop symbol designation command 32 stopped and displayed in each of the display areas 3a1 to 3c3 is switched to another display as a predetermined time elapses.

  As described above, in the second embodiment, after the fluctuation display is started by the fluctuation start command 30, the stop symbol designation command 32 and the variation pattern designation command 31 are transmitted in this order, and finally the symbol stop command 33 is transmitted. The change display is terminated. Therefore, since the display control board D can receive the stop symbol designation command 32 before receiving the variation pattern designation command 31, it is possible to replace symbols according to the variation pattern with good timing.

  Note that the variation pattern designation command 31 and the stop symbol designation command 32 only have to be transmitted to the display control board D during the high-speed variation of the symbol, and the transmission order is not necessarily a problem. Therefore, for example, the variation pattern designation command 31 and the stop symbol designation command 32 are transmitted in this order, or after several stop symbol designation commands 32 are transmitted, the variation pattern designation command 31 is transmitted, and then the remaining The stop symbol designation command 32 may be transmitted.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in each of the above-described embodiments, the control command of the present invention is directly transmitted from the main control board C to the display control board D that controls the variable display. However, instead of this, a control command is once transmitted from the main control board C to a sub board other than the display control board D, and a control command is sent from the sub board to the display control board D. Control the fluctuation display, or expand the control command in detail for each point where the fluctuation display changes by the sub board, and send the developed command from the sub board to the display control board D to change the display. The display may be controlled. In addition, if it is the latter structure, the control burden of the variable display in the main control board C and the display control board D can be reduced.

  The control command of the present invention was used for controlling the fluctuation display of the LCD display 3, but by using such a control command or its command system, a sound effect board for generating a sound effect and various lamps You may make it control the lamp board | substrate which blinks.
