Description

The present invention relates to a rotating game machine, and more particularly to a rotating game machine that facilitates a lottery processing operation.

  A ball game machine such as a pachinko machine has a symbol start port provided on the game board, a symbol display unit that stops after a plurality of symbols are variably displayed, and a big prize opening that is opened and closed by opening and closing plates. It is prepared for. Then, when the game ball wins after passing the symbol start opening, the symbol display unit starts the change of the display symbol, and then when the special symbol corresponding to the big hit state is aligned, the big winning opening is opened and many game balls are opened. Profits can be expected to be paid out.

  In this type of gaming machine, the jackpot counter is realized by software, and the value of the jackpot counter is updated every predetermined time (P) within a predetermined numerical range (0 to MAX-1). For example, in the case of the processing system as shown in FIG. 10A, a reset signal is given to the CPU every predetermined time (P), and the value of the big hit counter is updated in a part of the periodic execution unit ( ST30). In the case of the processing system as shown in FIG. 10B, the value of the big hit counter is updated in the interrupt processing (periodic execution unit) that occurs every predetermined time (P) (ST30).

  Then, when the game ball is introduced through the symbol start port, it is determined that the game ball has won (ST31), and a big hit determination process is performed based on the updated value of the big hit counter (ST32). As a result of the determination process, if the value of the jackpot counter (the random number for lottery) matches the jackpot winning value Hit, the special symbols are controlled to be aligned in the stopped state after the variable display in the symbol display section.

  By the way, in such a control, a big hit timing is invited every fixed time (= P × MAX), and since this state continues for a fixed time (P), the game is given to the symbol starting means at this timing. If the ball is detected, the big hit state can be always realized, and there is a problem that it is easily targeted by an unauthorized player.

  Therefore, it is conceivable that the jackpot counter is realized by hardware and updated at a speed considerably higher than the predetermined time (P) regardless of the system clock supplied to the CPU.

  However, in such a configuration, after the CPU obtains the value of the jackpot counter, it is necessary to perform arithmetic processing for matching with a preset numerical range (0 to MAX-1). Arises.

For example, even in the simplest case where the numerical value range of the big hit counter is 0 to 2 ^N −1, the CPU processing unit is an 8-bit unit or a 16-bit unit. Processing (X ← X AND 0011... 1) is required (see FIG. 11A). Further, when the numerical value range is other than 0 to 2 ^N −1, a correction calculation as shown in FIG. 11B is necessary, and there is a problem that the control is complicated accordingly.

The present invention has been made in view of such problems, and an object of the present invention is to provide a swivel type gaming machine that can simplify a series of lottery processes performed based on a counter value.

In order to solve the above problems, the present invention is advantageous to the player based on the acquired value of the counter during the circulation operation when the predetermined state resulting from the player's game operation is detected. A spinning-reel game machine for determining whether or not to generate a special state, a CPU circuit having a built-in memory, a system clock generator for generating an operation clock of the CPU of the CPU circuit, A random number generation circuit that is updated independently of an operation clock, the random number generation circuit performing an oscillation operation independently to oscillate a clock pulse that is not synchronized with the operation of the CPU, and based on the clock pulse The counter that performs counting operation, a buffer that outputs the value of the counter to the CPU, and an output value that is always received from the counter are determined in advance. It said counter outputs the clear signal or a preset signal reaches the reference value is composed of a match determining circuit for initializing the random number generating function in any numerical range except 0 to 2 N ^-1 logic circuit is realized In the success / failure determination process, the CPU acquires the output value of the buffer and determines whether to generate the advantageous state based on the single acquired value. The reference value is fixed in advance. It is configured so that it cannot be changed depending on the program.
A numerical value range generated by a simple 2 ^N- ary counter is 0 to 2 ^N −1. However, in the present invention, random numbers in an arbitrary numerical range other than 0 to 2 ^N −1 that cannot be generated by a 2 ^N- ary counter are used. appear. Match determining circuit of the present invention, when the counter value matches the reference value other than 0 to 2 N ^-1, the counter can be forcibly be called a initial setting means so initializing a.

  In the present invention, since the initial setting means is provided, the counter circulates within a predetermined numerical range, and no calculation is required for the acquired counter value. When the big hit probability is 1 / N, for example, by setting the reference value to N, the counter cyclically generates a numerical sequence of 0 to N−1, and the value is used as it is for determination of success / failure. it can.

  However, the counter according to the present invention is not limited to the up counter in which the generated numerical sequence increases sequentially, and may be a down counter in which the generated numerical sequence decreases sequentially. In the case of this down counter, the reference value is typically 0, but when the counter value matches 0, the initial setting means forcibly initializes the counter to a preset value. In this case, assuming that the preset value is M and the countdown operation is −1, the generated numerical sequence is M˜1.

The initial setting means can be configured without including a CPU for performing the determination, and the reference value is fixedly set in advance .

As described above, according to the present invention, it is possible to realize a rotating type gaming machine that can simplify the lottery process performed based on the value of the counter.

If it has not passed, the special game ends. However, if it has passed the specific area 18b, the special game is continued up to, for example, 16 times, and is controlled in a state advantageous to the player.

  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.

  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.

  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. 3, 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.

  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 are connected to the CPU. A computer circuit including a ROM, a RAM, and the like 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. .

  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 the one-way communication of the control command, it is possible to surely prevent fraud related to the symbol stop, to remarkably reduce the control load on the main control board 39, and to simplify the transmission control.

  FIG. 5 is a block diagram showing the configuration of the main control board 39. The main control board 39 of this embodiment includes a CPU circuit 50 having a built-in memory (ROM, RAM), a system clock generator 51 for generating an operation clock of the CPU, and a chip select signal for each part based on an address signal from the CPU. , A random number generation circuit 53 that is updated regardless of the operation clock of the CPU, an output port circuit 54 for outputting data from the CPU, and an input port for the CPU to take in external data The circuit 55, an output drive circuit 56 for outputting a command or the like to each control board, and a switch input circuit 57 for inputting ON / OFF states of switches of each part of the game board. Since this pachinko machine includes a random number generation circuit 53 having a configuration different from that of the system clock generation unit 51, there is no possibility that the operation of generating a numerical sequence in the random number generation circuit 53 is synchronized with the operation of the CPU.

  FIG. 6A is a circuit block diagram illustrating the random number generation circuit 53 in more detail. The random number generation circuit 53 receives an oscillator 60 using a crystal resonator, a counter 61 that is counted up based on a clock pulse φ (about 8 MHz) from the oscillator 60, and a request signal REQ from the CPU. A buffer 62 for outputting a value and a coincidence determination circuit 63 for outputting a clear signal for clearing the counter 61 to zero are constituted.

The coincidence determination circuit 63 is a logic circuit that always receives the output of the counter 61 and outputs a clear signal CLR when this value reaches a predetermined determination reference value (MAX). Therefore, although the counter 61 is a normal 2 ^N- ary counter, the numerical range is not fixed as 0 to 2 ^N -1, and the numerical range (0 to MAX-1) can be freely set according to the determination reference value. Can be set to In the example shown, the criterion value from the left side of the match determining circuit 63 (MAX) is set in advance fixedly (11010 ...), as to indicate by a broken line, via a buffer 64 Thus, the determination reference value (MAX) can be set from the CPU. In this case, there is an advantage that the numerical value range (0 to MAX-1) of the counter 61 can be freely changed by a program. However, such a configuration is not within the scope of the present invention.

  Next, the control program for the main control board 39 will be generally described with reference to FIGS. At the start of business, when the power switch 80 is switched on while pressing the initialization switch 85 with the front frame 4 of the pachinko machine 2 opened forward, the DC voltage is changed to the control boards 39-40, 42- Simultaneously with being supplied to 43 and 46, a system reset signal is supplied to each control board.

  As a result, the game control by the main control board 39 is started, and the control operation is also started in each of the control boards 40, 42, 43, and 46. When the game control is executed and the initialization switch 85 is in an ON state by a pressing operation (S1: yes), first, an initial setting process for initializing each memory and register of the CPU is executed (S2). Next, all the game information stored and retained by the backup power source in the RAM work area and information memory of the integrated circuit is erased (S3), and an initial symbol to be displayed on the first symbol display means 22 is set, Various initial value setting processes such as setting an interrupt cycle for periodically executing an interrupt process during the execution of the game control are executed (S4).

  On the other hand, when the initialization switch 85 is in the OFF state when the power is turned on (S1: no), a backup data restoration process is performed (S5). The backup data restoration process is a process for restoring the data backed up by the NMI process in the event of a power failure or the like, and this processing is performed when the power is turned on without pressing the initialization switch 85 after the power failure is restored.

  When the process of step S4 or S5 is completed, random number processing (S6, S7) for outliers repeated in an infinite loop is performed. The random symbol processing for the out symbol defines a out symbol pattern to be drawn on the liquid crystal display 16 when the special symbol lottery (S14) is interrupted in the interrupt processing described later.

  During such infinite loop processing, a timer interrupt occurs every fixed time (for example, 2 ms), and the processing shown in FIG. 8 is executed. In the interrupt processing program, the winning counter CT is first updated (S10), and then the switch signal input processing for reading switch signals from various switches including the winning detection sensor is executed (S11). . By this switch signal input processing, various information in the game board 5 including whether or not the game ball has passed through the gate 20 and whether or not the game ball has passed through the symbol start port 17 is grasped.

  Subsequently, a timer subtraction process is performed, and each numerical value TIME for the timer of the work area initialized in steps S13 and S14 is subtracted (S12). Next, the normal symbol process related to the normal symbol display part of the second symbol display means 23 is executed (S13). For example, if it is determined that the game ball has passed through the gate 20 by the current switch signal input process (S11), the normal symbol display unit 23 displays the value of the winning counter CT updated in step S10. It is determined whether or not a winning symbol is displayed.

  Then, when the winning state is achieved by this determination process, the time for displaying the normal symbol variably, the subsequent stop symbol, the subsequent open time of the electric tulip, etc. are determined, and numerical values corresponding to the variable display time, the open time, etc. TIME1 is stored in the work area of the RAM.

  Then, the process regarding a special symbol is performed (S14). For example, if it is determined by the current switch signal input process (S11) that the game ball has passed the symbol start port, the CPU requests the random number generation circuit 53 to obtain the random number RND for lottery. The signal REQ is output. The lottery random number value RND is input through the input port circuit 55.

  The lottery random value RND inputted is compared with the big hit winning value Hit to determine whether or not the big hit state should be set. And if it is a big hit state, after the fluctuation | variation of a special symbol stops, the time data TIME2 of how long the opening-and-closing board 18a is open | released is written in a work area.

  If there is a symbol control command to the symbol control board 40 or a control command to be output to the payout control board 46, the sound control board 43, or the lamp control board 42 after the special symbol processing (S14), that symbol should be output. An output process for outputting the control command to the destination control board is executed (S15).

  Finally, a drive signal output process for outputting a drive signal to the solenoid that opens and closes the opening / closing claw 17a and the opening / closing plate 18a is executed (S16), and the interruption process is completed. In the drive signal output process (S16), the contents of the work areas that are initially set in the processes in steps S13 and S14 and subtracted in the processes in step S12 are referred to. When the numerical value of each work area becomes smaller than a specific value, the solenoid is turned on. The opening / closing claw 17a and the opening / closing plate 18a are opened by being turned ON, and when the numerical value of each work area reaches 0, the solenoid is driven OFF to close the opening / closing claw 17a and the opening / closing plate 18a. The numerical values of the work areas are both 0 before the timer initial values TIME1 and TIME2 are set in steps S13 and S14.

  Next, the operation content in another embodiment will be described with reference to the flowchart shown in FIG. This game control program is executed due to a reset signal generated every certain time (for example, 2 ms), but the main process including a process for determining whether or not a big hit state is generated, and then the next reset signal is generated. It is roughly divided into residual processing that is performed in an infinite loop.

  When the reset signal is received, the CPU is initially set (ST1), and it is determined whether or not the start data is a normal value (ST2). The start data is data for recognizing whether or not the present time is power-on, and the specific data True is stored in the memory as start data when the main processing unit ends (ST12), and the value is stored. The determination is made in the process of step ST2.

  When the power is turned on, since the start data is confirmed as an abnormal value (≠ True), this is confirmed, so that initialization of the work area and initial setting processing are performed as initialization processing of the gaming machine (ST3). , ST4). On the other hand, if the start data is the normal value True, the winning counter CT is first updated (ST5). Hereinafter, the process from the switch input process (ST6) to the drive signal output process (ST11) is executed, and the contents thereof are the same as the contents of S11 to S16 shown in FIG. In addition, before and after these steps ST5 to ST11, a normal electric accessory process, a special electric accessory process, and other error detection processes are also performed. However, the explanation is omitted because it is not directly related to the gist of the present invention. .

  After completing such normal processing, the specific data (true) is stored in the memory as start data (ST12), and the main processing program is completed. Subsequently, a random number process for an out symbol is performed in an infinite loop until the next reset signal is generated (ST13). The random symbol processing for the off symbol defines the off symbol pattern drawn on the liquid crystal display 16 when the special symbol lottery (ST9) is off in the next main processing program.

  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, in the case of the above embodiment, the big hit counter is realized by hardware, and the hit counter CT is realized by software, but both may be realized by hardware.

  In the embodiment, the circuit of FIG. 6A has been described, but it is not always necessary to use the up counter 61, and a down counter 61 'may be used as shown in FIG. 6B. The down counter 61 ′ decrements (−1) the preset value in synchronization with the clock pulse φ. When the counter value reaches 0, this is detected by the coincidence determination circuit 63.

Then, the coincidence determination circuit 63 outputs the preset signal PSET to the down counter 61 ′, so that the value of the down counter 61 ′ is set again to the preset value (M), and then M → in synchronization with the clock pulse φ. M-1 → M-2... → 0 is decremented. In this circuit, the preset value may be set by the CPU , but this is not within the scope of the present invention.
