Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball game machine, and more particularly, to a bullet ball game machine that can realize game control that meets the user's preference without hindrance.
[0002]
[Prior art]
A ball and ball game machine such as a pachinko machine has a symbol starting means provided on the game board, a symbol display means for stopping a plurality of special symbols after a predetermined time fluctuation, a big winning means for driving the opening and closing plate, etc. It is prepared for. When the symbol starting means detects the game ball, the gaming machine enters a winning state (starting winning state), and the symbol display means starts the changing operation of the special symbol. In addition, the big hit determination means functions to perform, for example, a lottery process for extracting a lottery random value and comparing the extracted lottery random value RND with the big hit winning value Hit.
[0003]
In this lottery process, if the random number for lottery RND and the jackpot winning value Hit match, the special symbols are aligned in the stopped state after the change, and then the open / close plate is repeatedly opened and a large number of prize balls are paid out. A promising jackpot game is started. Note that the special symbol changing operation is performed regardless of the result of the lottery process. For example, the two special symbols are aligned first, and then the last one special symbol is changed for a predetermined time while being careful. Reach action is produced.
[0004]
As such a gaming machine, for example, an invention according to Japanese Patent No. 2966072 has been proposed. In this invention, when a new winning state occurs during a variable action including a reach action, the winning state is held up to the maximum number of holds (= 4), but the winning state exceeding this number does not contribute to the lottery operation. I am doing so. That is, when a new winning state is generated, only when the value of the start winning counter is less than 4, the success / failure data (R0 to R0 in FIG. 9A) is assigned to the predetermined address specified by the area number (1 to 4). R2) is stored.
[0005]
On the other hand, when reading the validity data stored in this way, the oldest pending data (R0 in FIG. 9A) among the unprocessed validity data is processed, and other data is subjected to a shift operation. Thus, the storage position is sequentially moved (see FIG. 9B).
[0006]
[Problems to be solved by the invention]
However, such conventional pachinko machines have problems to be further improved. First of all, with conventional pachinko machines, the problem is that the maximum number of holds is fixedly limited, and even though it is in a state of winning at the corner, there are about 15 prize balls over the fourth. If it only contributes to the ball payout, there is a risk that the player may be whitened. In other words, if there are actually start winning states one after another, the possibility of allocating a jackpot state should be given as much as possible.
[0007]
However, if the countermeasure is simply to increase the maximum number of reservations, the memory area is consumed correspondingly to the increase in the maximum number of reservations, which may hinder other game control operations. More specifically, the pachinko machine has only a minimum RAM area (for example, 256 bytes or 512 bytes) for the purpose of preventing damage caused by unauthorized modification. If the number is simply increased, the original work area and stack area cannot be taken sufficiently, and novel and advanced game control that meets the user's preference cannot be realized.
[0008]
The present invention has been made in view of such a problem, and it does not consume a RAM area even when the maximum number of reservations is increased, and can achieve game control that meets user preferences without hindrance. It is an object to provide a gaming machine.
[0009]
[Means for Solving the Problems]
  In order to solve the above problems, the present invention provides a variable display device that can change a display state and that can derive and display a plurality of types of display results, and the variable display device on the condition that a game ball is detected. Start means for variable time display operation, and predetermined information related to the game ball detected by the start meansHave a storage area that can store more than one bytePending storagePartAnd the reserved memoryPartHolding memory digesting means for performing variable display operation based on predetermined information for the number of held balls stored in the memory, and the variable display after the variable display operationapparatusIs advantageous to the player when a predetermined display result is derived and displayed.Big hit stateA predetermined game state generating means for generatingJackpotFor lottery processing to determine in advance whether or not to generate a gaming stateRandom lot value RND to be used, and the remaining bit length m of less than 1 byte ₁ 8 × 1 + m with ₁ First information of bit length and,Other random number ZU related to the lottery process, and the remaining bit length m of less than 1 byte ₂ 8 × 0 + m with ₂ It consists of second information of bit length,Of the first variable and the second variable that are updated in response to the write operation to the holding storage unit, the upper limit value of the holding ball number is managed by the first variable HORYU that specifies the holding ball number. Until the number of balls reaches the upper limit, the first information and the second information are stored in the storage area specified by the second variable NUM that cyclically instructs from the first address to the last address of the reserved storage unit. Combined 2-byte length is stored continuously.
[0010]
In the present invention, at least one byte in the storage area stores a plurality of different types of storage information, and typically a plurality of storage information is stored in combination with each other. Therefore, according to the present invention, a limited RAM area can be used effectively, and the maximum number of reservations can be increased without consuming much RAM area. If the writing means and the reading means that use the storage area cyclically are provided, the processing time does not increase correspondingly even if the start winning state is continuously generated. There is no risk of machine malfunction.
[0012]
The method of using the RAM area is not particularly limited, but the entire usable RAM area is divided into a stack area and a work area that are fixedly secured based on a game machine program, and other remaining areas. It is preferable to secure the area as a storage area (holding area A2) up to the limit position of the remaining area while partitioning. Here, the stack area is an area having a data structure of LIFO (Last-In First-Out), and is used when saving registers in interrupt processing or branching to a subroutine (including interrupt processing routine). This means the area used to store the return address. The work area means an area reserved for temporarily storing calculation results during execution of the control program including variable values and flag values.
[0013]
In general, in a gaming machine, the size of a usable RAM area W0 is limitedly determined by a public institution from the viewpoint of making illegal modification of the gaming machine difficult. On the other hand, the size W1 of the work area is fixedly determined according to the game machine program, and the size W2 of the stack area is also limited to the game machine program by limiting the nesting depth of interrupt processing. Accordingly, it is fixedly determined. For this reason, in the gaming machine according to claim 7, the size of the remaining area is determined as W0-W1-W2, and by using this remaining area to the full, Even when the winning state is entered, it is possible to hold the winning state as much as possible.
[0014]

An upper plate 8 for storing game balls for launch is mounted on the front plate 7, and a lower plate 9 for storing game balls overflowing or extracted from the upper plate 8 and launching means 10 at the lower part of the front frame 4. And a firing handle 11 are provided.
[0017]
The launching means 10 includes a launching handle 11 that can be rotated, and a launching motor that launches a game ball with a striking rod 12 (FIG. 4) with a striking force corresponding to the rotational angle of the launching handle 11. On the right side of the upper plate 8, there is provided an operation panel 13 for a ball lending operation for the card-type ball lending machine 1, and on this operation panel 13, a card remaining amount display portion 13a for displaying the remaining amount of the card with a three-digit number. And a ball lending switch 13b for instructing lending of game balls for a predetermined amount, and a return switch 13c for instructing to return the card at the end of the game.
[0018]
As shown in FIG. 3, the game board 5 is provided with a guide rail 15 made of a metal outer rail and an inner rail in a substantially annular shape, and a color liquid crystal is provided in the game area 5 a inside the guide rail 15. A display 16, a symbol start opening (design start means / winning means) 17 having a detection switch, an open / close type winning means (large winning means) 18, a plurality of normal winning means 19 (in addition to the upper normal winning means 19, an open / close type winning prize) Six normal winning means 19) and two gates 20 (passage openings) are arranged at predetermined positions on the left and right sides of the means 18, respectively.
[0019]
The liquid crystal display 16 functions as first symbol display means 22 that displays a special symbol in a variable manner and displays a background image, moving images of various characters, and the like. The first symbol display means 22 displays background images and characters in an animated manner, and has three (left, middle, and right) symbol display portions 22a to 22c arranged in the left-right direction. On the condition that the ball wins, the display symbols of the symbol display portions 22a to 22c are variably displayed (scrolled) for a predetermined time, and based on the lottery result corresponding to the winning timing of the game ball at the symbol start port 17. The special symbol is stopped with the determined pattern.
[0020]
A normal winning means 19 and a second symbol display means 23 are provided immediately above the liquid crystal display 16. The second symbol display means 23 has a normal symbol display unit for displaying one normal symbol. When a game ball that has passed through the gate 20 is detected, the display symbol of the normal symbol display unit fluctuates for a predetermined time, A stop symbol determined by a random number for lottery drawn at the time the game ball passes through the gate 20 is displayed and stopped. The symbol starting port 17 is provided with an electric tulip having a pair of left and right opening and closing claws 17a that can be opened and closed. When the normal symbols after the variation of the second symbol display means 23 are aligned, the opening and closing claws are arranged. 17a is opened for a predetermined time.
[0021]
The open / close-type winning means 18 includes an opening / closing plate 18a that can be opened forward. When a special symbol such as “777” is aligned after the first symbol display means 22 is changed, a special game called “big hit” is started. 18a is opened to the front side. There is a specific area 18b inside the openable winning means 18, and when the winning ball passes through the specific area 18b, the special game is continued.
[0022]
After the opening / closing plate 18a of the open / close winning means 18 is opened, when a predetermined time elapses, or when a predetermined number (for example, 10) of gaming balls wins and the opening / closing plate 18a is closed, the gaming ball is in the specific area 18b. If it has not passed, the special game ends. However, if it passes through the specific area 18b, the special game is continued up to, for example, 15 times, and is controlled in a state advantageous to the player.
[0023]
As shown in FIG. 4, on the back side of the front frame 4, a back mechanism plate 30 that presses the game board 5 from the back side is detachably mounted. The back mechanism plate 30 has an opening 30a formed on the top side thereof. A prize ball tank 33 and a tank rail 34 extending from the prize ball tank 33 are provided. Dispensing means 35 connected to the tank rail 34 is provided on the side of the back mechanism plate 30. A passage unit 36 connected to 35 is provided. The game balls paid out from the payout means 35 are paid out to the upper plate 8 from the upper plate discharge port 8a (FIG. 1) via the passage unit 36.
[0024]
The opening 30a of the back mechanism plate 30 is fitted with a back cover 37 mounted on the back side of the game board 5 and a winning ball discharge basket (not shown) for discharging the winning game balls to the winning means 17-19. Are combined. A main control board 39 is disposed inside a case 38 attached to the back cover 37, and a symbol control board 40 is disposed on the front side thereof (FIG. 2). Below the main control board 39, a lamp control board 42 is provided in a case 41a attached to the back cover 37, and a sound control board 43 is provided in a case 41b adjacent to the case 41a.
[0025]
A power supply board 45 and a payout control board 46 are provided inside the case 44 mounted on the back mechanism plate 30 below the cases 41a and 41b. As shown in FIG. 4, a power switch 80 and an initialization switch 85 are arranged on the power board 45. Cases 44 are notched at portions corresponding to these switches 80 and 85, and each of the switches 80 and 85 can be operated simultaneously with a finger.
[0026]
A launch control board 48 is provided inside the case 47 attached to the rear side of the launch means 10. These control boards 39 to 40, 42 to 43, 45 to 46, and 48 are independent boards, and the control boards 39, 40, 42, 43, and 46 excluding the power supply board 45 and the launch control board 48 have one chip. A computer circuit including a microcomputer is mounted, and the main control board 39 and the other control boards 40, 42, 43, 46 are electrically connected via a connector with a plurality of signal lines.
[0027]
The main control board 39 and the other control boards 40, 42, 43, 46 are electrically connected via a connector with a plurality of signal lines, and each control board 40, 42, 43, 46 is connected from the main control board 39. In addition, various control commands for executing a predetermined game operation can be transmitted by one-way communication. By adopting one-way communication of control commands, it is possible to reliably prevent fraud, to significantly reduce the control load on the main control board 39, and to simplify transmission control.
[0028]
The one-chip microcomputer used in this embodiment is composed of a CPU, ROM, RAM, and other ICs equivalent to Z80 (Zilog), but the one-chip microcomputer mounted on the main control board 39 includes A ROM storing a control program to be described later and a RAM having a storage capacity of 256 bytes are incorporated. The 256-byte RAM area is all reserved as a reserved area for winning balls (256-W1-W2 = W3 bytes), in addition to a W1-byte work area and a W2-byte stack area. The winning ball holding area is divided into a holding area A1 for normal hits with a length of 8 bytes and a holding area A2 for big hits with a length of W3-8 bytes.
[0029]
The holding area A1 for normal hit is an area that is used when a game ball passes the gate 20 while the normal symbol is changing or the electric tulip is opening, and the holding area A1 is 8 bytes long. Thus, it is possible to store up to four 2-byte long hit random numbers RG acquired when passing through the gate.
[0030]
On the other hand, the big hit holding area A2 is an area that is used when a special symbol is fluctuating or when a game ball passes the symbol starting port 17 during the big hitting operation, and is acquired when winning the symbol starting port 17 The jackpot random value BIG and the special symbol data ZU to be aligned when winning the jackpot lottery are compressed and stored in a 2-byte length. In this embodiment, the big hit random number BIG is a value within a numerical range of 0 to 03BCH (= 956), and the special symbol data ZU is set to a value within a numerical range of 0 to 0BH (= 11). ing.
[0031]
Therefore, among 16-bit data, special symbol data ZU is assigned to the most significant 4 bits, and the remaining 12 bits are assigned to the random number RND for jackpot, and a total of 16-bit data (2 bytes) is stored in the reserved area A2 for jackpot They are stored in order. In this embodiment, since the data stored at one time is 2 bytes long, the upper limit of the number of reserved big winning balls is [(256-W1-W2-8) / 2]. It is possible to greatly increase the number of winning holds for jackpots. Note that [] is a Gaussian symbol for calculating an integer value by rounding down the decimal point, but the following description will be made assuming that [(256−W1−W2−8) / 2] = MAX.
[0032]
FIG. 5 illustrates the reserved area A2 together with a part of the work area, and the storage capacity of the reserved area A2 is a total of MAX × 2 bytes from TOP + 0 to TOP + (2 × MAX−1). . The reserved area A2 has a ring buffer structure, and 2 bytes of data are written after the TOP + 2 × NUM address, while 2 bytes from the TOP + 2 × (NUM-HORYU) or TOP + 2 × (NUM-HORYU + MAX) address. Data is read out.
[0033]
Hereinafter, the control program stored in the ROM of the one-chip microcomputer will be generally described. When the power switch 80 is turned on while pressing the initialization switch 85 with the front frame 4 of the pachinko machine 2 opened forward at the start of business, the DC voltage + Vcc is applied to each of the control boards 39 to 40, 42. To 43, 46. As a result, the CPU mounted on the control boards 39, 40, 42, 43, and 46 is reset in power, the game control is started on the main control board 39, and the other control boards 40, 42, 43, and 46 are also started. The control operation is started.
[0034]
The game control operation on the main control board 39 is normally realized by a timer interrupt that occurs every predetermined time (2 milliseconds). 6 to 8 are extracted from the interrupt processing program resulting from the timer interrupt, the part related to the holding operation of the winning ball (start winning ball). In the interrupt processing program, first, update processing of the big hit counter BIG and the normal hit counter RG is performed (S1). Although the specific content of the update process is not particularly limited, it is simple to circulate a numerical string within a predetermined numerical range by increment (+1) processing.
[0035]
Next, switch related processing for reading information from various switches including the winning detection sensor of the symbol start port 17 is executed (S2). FIG. 7 shows the contents in detail. In the switch-related process, the switch signal input process is first executed, and information on the game board 5 including whether the game ball has passed through the gate 20 and whether the game ball has passed through the symbol start port 17 is grasped. (S20).
[0036]
Subsequently, it is determined whether or not the big hit holding area A2 is full by comparing the data of the HORYU address (variable HORYU) with the maximum holding value MAX (S21). If HORYU <MAX, it is determined whether or not the symbol start port switch is in the ON state based on the information grasped in step S20 (S22).
[0037]
As a result of the determination, if the symbol start port switch is in the ON state (start winning prize state), the lottery random number RND (2 bytes) is acquired as the value of the big hit counter BIG updated in step S1, and the special symbol is also obtained. Data ZU (1 byte) is determined (S23). The special symbol determined here means a winning symbol that is arranged after the changing operation in the symbol display units 22a to 22c when the big hit state is won by the big hit lottery process in step S38 (FIG. 8).
In addition, when the “specific symbols” that are positioned at a particularly high value among the special symbols are arranged on the symbol display units 22a to 22c, a game state of a so-called probability change mode in which the big hit probability in the subsequent game is increased. In any case, the symbol data ZU for determining these operations is updated randomly in the main routine executed between the interrupt processing and the interrupt processing that occur intermittently. The value is obtained as it is.
[0038]
Next, the acquired 3-byte data (RND, ZU) is compressed into 2-byte data (ST24). Although the compression method is not particularly limited, in the present embodiment using the Z80 CPU, for example, the processing as shown in FIG. 9 is adopted. First, the jackpot random number value RND is taken into the HL register, and the special symbol data ZU is taken into the A register (S23). Then, after shifting the value of the A register by 4 bits to the left, the OR operation is performed on the values of the A register and the H register, and the operation result is transferred from the A register to the H register (S24).
[0039]
The compressed 2-byte length data (HL register value) is stored in the corresponding area of the big hit reservation area A2 starting from the TOP address (S25). The specific storage destination is determined by the contents of the NUM address. For example, if NUM = 13, 16-bit data in the HL register is stored in the TOP + 13 × 2 address and the TOP + 13 × 2 + 1 address ( S25).
[0040]
Thereafter, the contents of the HORYU address are incremented, and the number of winning holds (the number of unprocessed winnings) is counted up (S26). Also, the contents of the NUM address are incremented to designate the next writing area (S26). FIG. 5 schematically illustrates the state after the process of step S25.
[0041]
Subsequently, it is determined whether or not the data at the NUM address exceeds the limit value (MAX-1) (S27). If the data exceeds the limit value, zero is stored at the NUM address and the processing related to the reserved area A2 is finished (S28). ). In the reserved area A2, MAX areas (= 2 * MAX bytes) from TOP + 0 to TOP + 2 * MAX-1 are reserved. If NUM = MAX, the area to be written next is returned to the position of TOP + 0. It is. The case where the start port switch is in the ON state has been described above, but the same processing is performed when the switch of the gate 20 related to the lottery for determining whether or not the normal hit is ON.
[0042]
When the switch-related process (S2) is completed as described above, the process proceeds to step S3 in FIG. 6, and whether or not the current gaming machine is executing a normal hit operation is determined based on the work area flag value F1. (S3). If the normal hitting operation is in progress, the operation is continued (S5). Otherwise, the normal symbol processing related to the normal symbol display portion of the second symbol display means 23 is executed (S4). In the normal symbol process, for example, if it is grasped that the game ball has passed through the gate 20 by the current switch signal input process (S20), according to the value of the normal hit counter RG updated in step S1, It is determined whether or not the normal symbol display unit 23 displays a winning symbol.
[0043]
When the processing of step S4 or S5 is finished, it is next determined whether or not the gaming machine is currently in a big hit operation based on the flag value F2 in the RAM area (S6). The operation is continued (S8), and if not, the process related to the special symbol is executed (S7). FIG. 8 shows a part of this special symbol process in detail.
[0044]
As shown in FIG. 8, in the special symbol process, first, it is determined whether or not the special symbol is changing in operation (S30). If the variable operation is not in progress, whether or not the content of the HORYU address is 0 or not. Is determined (S31). As described above, in the winning state, the number of held in the winning state is stored at the HORYU address (S26 in FIG. 7).
[0045]
Therefore, if HORY ≠ 0, first, the storage position of the data to be read is calculated by the operation of NUM-HORYU (S32). However, in the present embodiment, the reserved area A2 composed of MAX areas is used cyclically, and therefore, when NUM-HORY <0, the correct position is further calculated by calculating + MAX (S34). .
[0046]
As described above, since the storage position of the data to be read is specified, the 2-byte data at the TOP + 2 × X address and the TOP + 2 × X + 1 address is acquired (S35). Next, the acquired 2-byte data is expanded into 3-byte data (S36). The decompression process in step S36 corresponds to the compression process in step S24, and the most significant 4 bits of the 2-byte data are masked to obtain a 12-bit long jackpot random value RND. In addition, the upper 8 bits of the 2-byte data are shifted to the right by 4 bits to obtain 4-bit symbol data ZU. When the above expansion process is completed, the contents of the HORYU address are decremented to decrease the number of winning-pending holds (S37).
[0047]
When the pending data read process (S32 to S37) is completed in this way, the lottery process is performed based on the random number for lottery RND developed in the process of step S36 (S38). That is, the lottery random number value RND determined in the process of step S36 is compared with the big hit winning value Hit to determine whether or not, and processing corresponding to the result is performed. For example, in the big hit state, after the change of the special symbol is stopped, the time data TIME2 indicating how long the opening / closing plate of the special winning opening 18 is opened is written in the work area.
[0048]
When the processing in step S8 or S7 shown in FIG. 6 is completed as described above, processing such as outputting a control command to the symbol control board 40, the payout control board 46, the sound control board 43, the lamp control board 42, etc. is executed. (S9). In addition, the data of the HORYU address (the number of winning balls held in relation to the big hit) is numerically displayed at a position visible from the front of the gaming machine. Therefore, the player can surely grasp the number of held balls, no matter how many the number of winning balls held. In addition, a driving signal output process for outputting a driving signal to a solenoid for opening and closing the opening / closing claws and the opening / closing plate of the symbol start opening 17 and the special winning opening 18 is executed, and the interruption process is completed.
[0049]
As mentioned above, although the Example of this invention was described, it has only illustrated the specific example and does not specifically limit this invention. For example, the content of the interrupt processing described in the embodiment is merely an example, and can be changed as appropriate, and the data length of the compressed data stored in the holding area A2 may be changed. In this embodiment, the jackpot random number RND and the symbol data ZU are integrated and compressed and stored in the holding area A2. However, other data may be added in addition to the data RND and ZU. However, instead of the jackpot random number value RND and the symbol data ZU, other data may be stored.
[0050]
【The invention's effect】
As described above, according to the present invention, it is possible to realize a bullet ball game machine capable of smoothly continuing the game control even when the game machines are continuously in the start winning state.
