Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine using a computer. 2. Description of the Related Art Some recent pachinko machines use a computer to electronically control the winning probability of a ball. In such a pachinko machine, in order to determine a hit mode, an event that depends on contingency is generated, a hit mode is determined from the event, and the development of a more complicated game is controlled in accordance with the hit mode. ing. However, the output devices such as the light emitting device and the sound emitting device perform only simple controls such as single sound and single light emission. There is a demand for control. [0003] However, in the conventional pachinko machine, the processing capacity is becoming saturated due to the control mainly of such complicated game development, and the program development must be advanced by one person. I had to. For this reason, in controlling the output devices such as the sounding device and the light emitting device, more complicated control, for example, depending on the progress of the game, each sound is composed of more musical sounds, and continuous music having a melody is played. It is difficult to perform output or control to generate complicated illumination. In addition, since the control target of the computer becomes complicated and increasing in this way, the control program becomes long, and the capacity of a storage device for storing the control program also needs to be increased. However, in pachinko machines, the capacity of the storage device is limited due to the regulations of the organization that monitors fraud. For this reason, under the regulation of the limitation of the storage capacity, it is required to perform more complicated and more control. On the other hand, in pachinko machines, the number of CPUs used is not limited, but there is little necessity to process a large amount of work at high speed, and a plurality of CPUs are not used in pachinko machines. Therefore, an object of the present invention is to enable more complicated and more processes without increasing the storage capacity due to the limitation of the storage capacity. Means for Solving the Problems The structure of the present invention for solving the above problems is as follows. That is, the present invention provides a winning detection device that detects a winning of a ball in a specific winning opening, determines a winning mode with a higher winning probability according to the winning in the specific winning opening, and sets the winning mode to the mode. Accordingly, in a pachinko machine including a control device for controlling a winning probability of a ball to a winning opening and for driving an output device such as a light emitting device and a sound generating device, the control device is provided on a first chip and a second device. And a dual one-chip microcomputer in which the central processing unit is formed.
The division of labor between the two central processing units of the dual one-chip microcomputer includes, for example, the following means. The first is a method in which the first central processing unit controls the winning probability, mainly manages the progress of the game of the pachinko machine, and the second central processing unit performs other tasks. Second,
This is a method in which the second central processing unit controls at least one of the sound emitting device, the light emitting device, and the other output device, and the first central processing device performs other tasks. Third, there is a method in which the second central processing unit performs a process for generating an event that depends on contingency, and the first central processing unit performs other work. The first central processing unit of the dual one-chip microcomputer is used, for example, for main processing for controlling the progress of a game, and the second central processing unit is a sound emitting device, a light emitting device, and the like. It is used for sub-processing for controlling the output device. Since these two central processing units can use the storage device exclusively or in common, they can store their own programs, manage common data in common, and simplify the processing of complicated games. . In addition, since real-time parallel processing becomes possible, for example, management of the progress of the game and management of the output device can be performed separately in parallel. Therefore, more detailed and complicated control can be performed. Also, since two central processing units are used, 1
Unlike the case where the interrupt processing is performed by two central processing units, it is not necessary to perform the processing specific to the interrupt processing such as the saving of the register, so that the operation is efficient.

FIG. 1 is a block diagram showing an electrical configuration of the apparatus according to the present embodiment. As the control device, a dual one-chip microcomputer 1 (hereinafter, referred to as "dual computer") is used. The dual computer 1 has two central processing units, CPU1 and CPU2, and can access the internal ROM and the internal RAM from both. Each CPU automatically and alternately executes one step at a time according to its own program (auto-swap mode), or controls the other CPUs under program control of the operating CPU.
(Program swap mode). An external ROM 3 and an external RAM 5 are connected to the dual computer 1 so as to be accessible from both CPUs. A winning detection switch 7 for detecting a winning ball in a special winning opening, a special winning opening winning switch 9 for detecting a winning ball in a special winning opening, and a V winning detection switch 11 for detecting a winning ball in a V winning opening prevent chattering. Connected to the dual computer 1 via a waveform shaping circuit 13 composed of flip-flops for performing the operation. The above-mentioned switch is constituted by a limit switch, and is arranged on a rail for guiding a winning ball from each winning opening. The clock generation circuit 17 is 4 MHz
Is output to the dual computer 1 and a signal is output to the frequency divider 15. Frequency divider 15
Divides the clock signal and outputs an external interrupt signal having a period of 4.096 msec to the dual computer 1. The main control of the dual computer 1 is started in synchronization with this interrupt signal. Reference numeral 21 denotes a power supply circuit. The signal of the start switch 23 is input to the reset signal generation circuit 19, and the reset signal, which is the output signal, is input to the reset terminal of the dual computer 1. The program is executed. Each output port of the dual computer 1 has a display drive circuit 25, a display selection circuit 31, a software controlled sound generator (hereinafter simply referred to as "SSG") 3
3. The driver 39 is connected. Display drive circuit 2
5. The display selection circuit 31 includes the numerical display 2 described above.
7, a lamp display 29 and a stored number display 30 are connected. These displays are dynamically driven by outputting selected data and display data from the dual computer 1 at regular intervals. That is, each display unit is selected by the display selection circuit 31 and is displayed according to the output signal of the display drive circuit 25 at that time. SSG33
Inputs control data for sound output from the dual computer 1 to each register, D / A converts a waveform created based on the control data, and outputs the converted waveform to the speaker 35. The driver 39 drives the solenoid 41 in response to a signal from the dual computer 1 and controls the lighting operation of the panic lamp 43, the V lamp 45, and the operation lamp 47. Next, the operation of the pachinko machine having such a configuration will be described with reference to a flowchart showing the processing procedure of the dual computer 1. (1) When the initial set start switch 23 at the time of power-on is turned on, power is supplied to the dual computer 1 and the reset signal generation circuit 19
Outputs a reset signal S4 to a reset terminal. Then, the CPU 1 executes the processing shown in FIG. That is, the numerical display registers X1, X2, and X3 storing the three-digit numerical values displayed on the numerical display 27 are set to the initial values, and the display lamp register L storing the lighting lamp of the lamp display 29 is set to the initial value. Set to the initial value. Also, a winning prize ball counter C for counting the number of prize balls winning and holding the specific prize port is set to zero, a special prize port winning counter G for counting the number of prize balls to the special prize port is set to zero, and V A V winning ball counter A for counting the number of winning balls to the winning port is initialized to zero. The state register F storing the control state is initialized to zero, the hit mode register R storing the hit mode is initialized to zero, and the timers T1, T2, T3 are initialized to zero. Further, the swap flag S storing the swap state of the CPU 1 and the CPU 2 is reset. (2) After the initial setting of the background processing, the CPU 1 executes the program shown in FIGS. 4 and 5 every time an external interrupt signal is input at regular time intervals (4.096 msec). In step 100, a timer updating process is performed, and in step 102, the state signals S1, S2, and S3 of the switch group are read. These status signals are configured by negative logic, and indicate that the switch is on when the signal is at a low level, and that a winning ball is detected. Therefore, steps 104, 110, 11
4 detects the falling of each state signal, and only at that time,
Each counter C, G, A is updated by one. However, the number of prize balls held is counted up to only 4 in step 106. Step 118 to Step 1
66 is a processing step corresponding to each state. Steps 170 to 192 are processing steps of the output device. When the hit mode register R is 0, the solenoid 41 is turned off, so that the special winning opening is closed or the closed state is maintained. When the register R is other than 0, the solenoid 41 is turned on, so that the special winning opening is opened or is kept open (steps 170-1).
74). That is, the opening and closing of the special winning opening is controlled by the contents of the register R. Numerical value display 27 includes registers X1,
The values of X2 and X3 are displayed, and the lamp display 29 lights the LED specified by the register L (step 176).
When the register F is 1, that is, during the combination operation, the operation lamp 47 blinks, and when the register F is 2, that is, when the special winning opening is in the open state, the operation lamp 47 and the panic lamp 43 blink. , Register F is 2 and counter A is 0
If not, that is, if there is a V winning ball, the V lamp 45 is turned on. Further, the value of the counter C is displayed on the stored number display 30 (step 178). Step 180
Steps 192 to 192 are steps for driving or stopping the CPU 2 in the auto swap mode in accordance with the presence or absence of sound generation control. At the time of sound control, that is, when the register F is other than 0, the swap flag S is set and the auto swap is started, and thereafter, the CPU 1 and the CPU 2
It will operate alternately step by step. When the register F becomes 0, the tone generation control is stopped, the swap flag S is reset, the auto swap is stopped, and thereafter, only the CPU 1 operates. (3) Processing when there is no winning ball When there is no winning ball, that is, when the counter C is 0, the processing of steps 100 to 124 and 170 to 192 is performed, whereby the numerical value is set. The display, the lamp display, and each lamp group perform a predetermined display. (4) When a winning ball exists (C ≠ 0) (a) The value of the counter C is determined in the combination operation processing step 124, and when a winning is detected, the value of the counter C is decremented by one. The register F is set to 1 to indicate the combination operation state, and the timer T1 is set to a predetermined value (steps 124 to 130). Then, in step 132, a random number generation process is performed, and the generated random numbers are stored in the registers X1, X2, X3, and L. Until the time is up in step 134, step 100
To 118, 132, 134, 170 to 192 are repeated. The setting of the random numbers is performed every time the process passes through step 132. When the time is up, in step 136, the registers X1, X2, X3, L
Is set in the register R, and the mode is set in the register R. 0 is out, 1 is small hit, 2 is medium hit, and 3 is big hit. If it is off, the register F is set to 0, and the process proceeds to the cycle for determining the next winning ball. (B) Winning process When the result of the determination in step 136 is a hit, a time is set in the timer T2 according to the hit mode. Then, the background processing described above is performed until it is determined that the time is up. As a result, the special winning opening is opened for a predetermined time, the lamp group is displayed to indicate a panic state, and music in a panic state is played from the speaker 35. At this time, if the number of winning balls in the special winning opening reaches 10, the same processing as the time-up is performed even before the time-up. That is, the counter G is set to 0 and the register R is set to 0 (steps 150 and 152). (C) Processing when a V Win Ball Exists The V win ball exists when the large winning opening is open, that is,
If the counter A is not 0 (step 156), step 1
At 58, the value of the register F is set to 3 to indicate the generation of the continuation right. Then, the counter A is decremented by 1, and the timer T3
Is set to a predetermined time, and time up is determined (steps 158 to 164). This process is for giving a certain delay until the special winning opening is subsequently opened. Thereafter, in step 166, the register R is set to 3 indicating a big hit, and the process proceeds to step 142 to perform the above-mentioned hit processing. However, the continuation right is adjusted in step 152 so as not to occur more than ten times. (5) Processing for sound generation control In the background processing of steps 180 to 192, it is determined that the state is sound generation control.
The PU 2 executes the processing of FIG. 6 in parallel with the processing of the CPU 1 macroscopically. In step 200, the sound generation mode is determined from the values of the status register F, the winning ball counter C, the winning mode register R, the special winning opening winning counter G, and the V winning ball counter A, and the value is set in the register W. The ROM 3 stores a control data group for outputting a different melody for each tone generation mode, as shown in FIG. The control data includes a set of sounding data such as a sound frequency, a sound volume, and an envelope, and time data indicating the sounding continuation time of the sound. In step 202, it is determined whether or not the tone generation mode has changed from the change in the value of the register W. Set to P. Next, step 206
To store the contents of the address indicated by the data pointer P in the ROM.
3 and if it is not the end code of the data, at step 210, time data is set in the timer based on the control data. Next, in step 212, the pronunciation data is
By outputting to each register of G33, the speaker 3
From 5 onward, one sound is generated until it is determined in step 214 that the time is up. Next, when it is determined in step 214 that the time is up, the process proceeds to step 216, where the data pointer P is updated to the address of the next control data, and the process returns to step 200. If it is determined in step 202 that there is no change in the sounding mode, the initial setting of the address is jumped, so that sounding data of the next sound in the mode is input. As described above, in the present embodiment, one of the two CPUs of the dual computer is used for the main control of the pachinko machine, and the other CPUs are dedicated to the control of the sounding device, which has complicated control. Used in Therefore, it is only necessary to develop an independent program for each, so that the production is simple. Further, the CPU 2 can be used for controlling a lamp group. As shown in FIG. 8, the control data includes, as a set of light emission data designating which one of a plurality of lamps is to be turned on, and time data for maintaining the state, as a set of data. It is created for each light emission mode. The processing procedure of the CPU 2 is the same as that of FIG.
By replacing 04 with the setting of the initial address corresponding to the light emission mode, Step 210 with the setting of the time data, and Step 212 with the output of the light emission data, dynamic light emission control according to the control data is possible. Further, the CPU 2 can be used for addition of the number of times of driving the numerical value display, the number of times of opening the special winning opening in the big hit mode, and other statistical processing. According to the present invention, there is provided a winning detection device for detecting a winning of a ball in a specific winning opening, and a winning mode having a higher winning probability in accordance with the winning in the specific winning opening is provided. In a pachinko machine including a control device that controls the winning probability of a ball to a winning opening according to the mode and drives an output device such as a light emitting device and a sound generating device, the control device is mounted on a single chip. And a dual one-chip microcomputer in which first and second central processing units are formed. Therefore, the two central processing units can execute in parallel while sharing necessary data according to their own processing programs, so that different jobs can be processed simultaneously. For this reason, it becomes possible to make the game development of the pachinko machine more complicated, to output a melody composed of complicated musical sounds in parallel with the progress of the game, and to realize lighting that fluctuates in a complicated manner, More entertaining can be improved. In addition, the development of the program can be performed independently by each central processing unit without being affected by the programs of the other central processing units. Therefore, the development of the game program and the development of the program such as the sound control can be performed by the respective specialists, and the development of the device becomes easy. Further, if a single CPU performs a parallel operation of tasks, a stack area for saving a program and register data for a task switching process such as a save process for a register or the like is required. Since each task is executed by using two CPUs, there is no need to spare the CPUs for executing other tasks. As a result, the stack area for saving the program for the task switching process and the data of the register is not required, so that the capacity of the storage device can be saved.
