A variable prize winning device 22 for converting into any of them is provided. Then, when the special symbol display 6 is displayed in a predetermined combination and a big hit occurs, the lid 24 is opened, and in the opened state, the upper surface of the lid 24 performs a guiding action, and the game is played to the special winning opening 23. While guiding the ball, when a game ball enters the specific area 25, the ball is detected by the specific area switch S ₃ (see FIG. 4), thereby causing a continuous opening operation, and a predetermined gain is provided to the player. . Further, a count switch for counting the number of winnings during the big hit is also provided in the big winning opening 23.

Next, the operation of the pachinko gaming machine 1 will be described. When a game ball flows in from the symbol starting area 14, the special symbol display 6 is driven together with the supply of the premium ball. In the case of continuous passage, the ball detection by the start switch is stored in the start storage device (RAM), and based on the storage, the LEDs of the start storage number display device 8 are sequentially turned on as described above, Held up to four times. Each time the symbol starts to fluctuate, this LED is turned off, and the number of memories decreases.

When the special symbol display 6 is driven, the special symbols A, B, and C start to fluctuate according to the symbol permutation shown in FIG. 5, and after about 6.5 seconds or more, the order of the special symbols A, B, and C changes. At the same time, the design fluctuation stops. When the special symbols A, B, and C have the same symbol combination as described later, a jackpot is generated, the sound generator (see FIG. 7) emits a fanfare, and the large winning opening opening solenoid of the variable winning device 22 is opened. (See FIG. 3), the lid 24 tilts forward, and the special winning opening 23 is opened. This opening is continued until the winning of 10 game balls is detected based on the detection of the 10 count switch (see FIG. 3) or a predetermined time has elapsed. The sea urchin I described above, passes through the specific region 25 of the winning opening 23, when the character object continuous operation switch S ₃ is turned ON, and continuously driven, the special winning opening 23 is opened again after the opening operation ends. The number of times of this continuous operation is up to 16 times including the initial opening, and this number is counted by the above-mentioned count switch. After 30 seconds, even if the number is less than the specified number, the special winning opening 23 is closed.

The control mode will be described in detail. The above-mentioned symbol variations of the special symbols A, B, and C are controlled by a game control device 50 including a microcomputer including a central control device CPU and the like shown in FIG. Here, a storage device ROM and a storage device RAM are connected to the central control device CPU. In the storage area of the storage device RAM, the ball detection signals from the special symbol start switch S ₁ and the ordinary symbol start switch S ₂ are stored up to a predetermined number.

Further, a special jackpot random number K composed of 0 to 426 frames is stored in the storage device ROM. Then, ball enters in the symbol start area 14, when the sphere detected by the special symbol start switch S _1, the random number value is selected at that time, its contents are stored in the storage equipment RAM. When the symbol starts to fluctuate, the stored contents are examined. If the symbol has a low probability, it is "7", and if the symbol is a high probability, it is "7", "13", "23", "42", "47". If it hits, the rest is lost. The description of the probability fluctuation is omitted since it is not a main part of the present invention.

The storage device ROM stores a winning symbol random number L selected based on the result of the jackpot special random number K and a lost symbol random number Ma, Mb, Mc, and a stop symbol is determined based on a hit or a miss. Determine the design.

Further, a reach random number N of 0 to 28 is stored in the storage device ROM. Since the reach random number N has a plurality of types of special reach variation display modes different from the non-reach state in the variation display mode, it determines which of the reach variation display modes to perform the reach operation. This is selected in the case of a jackpot design, and in the case of a lost design where A = B.

Next, a symbol display mode using each of the above random numbers will be described. First, a pattern starting region 14 through the balls special symbol start switch S ₁ is turned on work movement, selects the jackpot special random number K with the according sensing signal generator, determines the per or off. In this process, if the number of stored memories is full (four), it is invalidated even if a ball passes through the symbol starting area 14, or if it is fluctuating, the number of stored memories is invalid. Are added. Then, the special symbol display 6 fluctuates via the symbol control device 51 based on the ball passing into the symbol starting area 14 or the subtraction of the number of starting memories.

[0025] When the jackpot special random number K is K = 7 is selected jackpot, with the occurrence of a sphere detection signal from the special view pattern start switch S _1, or if it is stored in the start-up storage unit Changes the special symbols A, B, and C along with its memory digestion, and selects a value from the jackpot symbol random number L shown in FIG. 3 to determine the winning symbol. Furthermore, the reach random number N is drawn by lot, and it is determined in which special variation display mode the reach operation is performed. Here, the jackpot symbol random number L is composed of 15 frames from 0 to 14, and a winning symbol corresponding to the frame is selected.

Then, the special symbols A and B are sequentially circulated and fluctuated and stopped, and are brought into a reach state so as to become the same symbol, and after executing a predetermined special operation mode designated by the reach random number N, the special symbol is executed. C stops the symbol and is determined in advance by the jackpot symbol random number L, as shown in the lower row, “1,1,1”, “2,2,2”, “3,3,3”, “4,4” Combinations of the same symbols consisting of numbers such as "4" are displayed on special symbols A, B, and C so that the winning symbol is formed. Then, a "big hit" is reached, and the above-mentioned variable winning device 22 is operated.

On the other hand, if K is not a winning frame, a loss occurs, the special symbols A, B, and C are changed, and the loss symbol random numbers Ma, Mb, Mc are sequentially selected, and the special symbols A, B, and C are lost. indicate. At this time, when the symbol selected from the lost symbol random numbers Ma and Mb becomes the special symbol A = B, the reach random number N is randomly selected and the reach operation is performed in a predetermined reach variation display mode. In this way, if a winning symbol is obtained, a lost symbol random number is selected again so that a lost symbol mode is obtained.

Next, the normal symbol operation will be described. When playing ball passes the normal symbol start gate 13, the recreation sphere is detected by a normal symbol start switch S ₂ (see FIG. 3). Once sphere detection by the normal symbol start switch S _2, as shown in Figure 4, the normal symbol ordinary symbol display device 10 is changed. This normal design is composed of three LEDs, left red, middle green and right red.

When a ball is detected by the ordinary symbol start switch S ₂ while the ordinary symbol display device 10 is fluctuating or the ordinary electric accessory 15 is being opened, the ball is stored in an ordinary start storage device (RAM). The detection is stored, and the LED of the normal symbol start storage number display device 12 is turned on as the stored number is exhausted, and is turned off each time the normal symbol starts to change, and the stored number is displayed. Note that the maximum number of symbols to be stored in the normal symbol start storage number display device 12 is four, and any other symbols are invalid.

After the fluctuation of the ordinary symbol display 10 or the end of the opening operation of the ordinary electric accessory 15, the ordinary symbol display 10 starts to fluctuate again based on the starting memory of the ordinary start storage device (RAM). After about 28 seconds elapse after the normal symbol display 10 starts to fluctuate, the fluctuation stops, and if at least one of the left and right LEDs is lit, it is a hit, and the normal electric accessory 15 is opened for about 0.5 seconds. You.

The symbol variation control of the series of the special symbol display 6 and the ordinary symbol display 10 described above is executed by a control command means constituted by a game control device 50 including a central control device CPU and the like shown in FIG. The central control unit CPU executes a control operation according to a predetermined procedure, and is connected to a storage device ROM for storing an operation program and a storage device RAM for reading and writing necessary data as needed. The storage device ROM stores fixed data such as a control program, a random number table, a big hit game pattern, a display pattern of lamps and LEDs, a sound generation pattern for generating a sound effect from a speaker, and the like. Then, the above-described various random numbers are stored in the random number table, whereby each lottery is performed along each of the above-described steps.

This central control unit CPU has a special symbol start switch provided in the special symbol start area 14 via an input port, a normal symbol start switch S ₂ , a 10 count switch in the special winning opening 23, and a continuous character role. An operation switch is connected, a signal sent from each switch is waveform-shaped by a waveform shaping circuit, transmitted to a central control unit CPU as input data, and the information is stored in a storage device RAM. Further, the storage device AM has a storage area for temporarily storing data and the like for determining the stop display mode of the special symbols A, B, and C displayed on the special symbol display 6, a register area constituting a soft timer, and a game control device. Fifty work areas and the like are provided. The storage device RAM includes an address bus (not shown) for unidirectionally transmitting information designating an address for reading and writing data to and from the memory, and a data bus for exchanging data with the central control unit CPU, the storage device ROM, and the RAM.

The symbol control device 51 includes an LCD variable display CPU and a driver, and the driver is connected to a special symbol display 6 composed of a liquid crystal display to control the symbols. In a storage device (not shown) of the symbol control device 51, variable display data to a liquid crystal display (special symbol display 6), fixed data such as a display pattern and a big hit display mode are stored.

Thus, the game control device 50 including the central control device CPU and the like and the symbol control device 51 constitute the symbol control means according to the present invention.

Next, the main part of the present invention will be described with reference to the wiring diagram of FIG. The main board 60 houses the above-described central control unit CPU, storage device ROM, RAM, and the like.

On the other hand, the main board 60 controls not only the control on the game board but also the control of the entire pachinko game machine, such as the control of payout of prize balls, the control of the launching motor, and the exchange of data with the device outside the game machine. Therefore, usually, signal lines are collected for each relay board corresponding to each function, and a centralized management is performed by connecting a collective cable from each relay board to the main board. In this figure, in addition to relay boards such as a board relay board 61, a game frame relay board 62, a payout relay board 63, a winning opening relay board 64, a payout control board 66, a special symbol control board 67, a voice A control board 68 and the like (each corresponding to the concept of a relay board in the present invention) are provided and connected to the main board 60. Each switch is connected to a relay board for each type and transmitted to the main board via the relay board, thereby facilitating wiring on the back of the game board and providing a well-organized control circuit as a whole.

Various detection switches for detecting the passage of game balls in the area are provided. In other words, the winning prize opening switch, the lower left prize opening switch, the lower right prize opening switch, the left sleeve prize opening switch, the right sleeve prize opening switch, and the large prize opening switch provided for each winning opening are provided on the board relay board. 61 are connected via lead wires, each lead wire is assembled into a collective cable via a connector in the board relay board 61 and pulled out from the board relay board, and this collective cable is used for main control for centrally controlling the pachinko machine. Connected to main board 60. Thus, the required control is performed by inputting the ON / OFF information of the detection switch to a central control unit CPU provided in the main board 60. Then, the detection signal from each winning switch is sent to the main board 60 via the board relay board 61, becomes a payout control command from the main board 60, and is sent to the payout control board 66 and the payout relay board 63, A predetermined prize ball is paid out by operating the prize ball payout motor.

Further, the left gate switch and the right gate switch, which are ordinary symbol start switches S ₂ mounted on the left gate and the right gate, are also connected to the main board 60 via the board relay board 61. The detection signal from each switch is sent to the main board 60 via the board relay board 61, and is sent again from the main board 60 as a control command to the board relay board 61, a normal symbol display board, and a normal symbol. This is a trigger for changing the display 10.

Further, the accessory continuous operation switch S ₃ (specific area switch) is connected to the main board 60 via the special winning opening relay board 64 and the board relay board 61. Then, the signal detected by the accessory continuous operation switch S ₃ is sent to the main board 60 via the special winning opening relay board 64 and the board relay board 61, and as a control command, a payout control board 66, a payout relay board A predetermined winning ball is paid out by operating the prize ball payout motor and a trigger for opening the special winning opening a predetermined number of times.

That is, the detection signal by the special symbol start switch S ₁ is sent to the central control unit CPU in the main board 60, sent as a payout control command to the payout control board 66 as an output signal from the central control unit CPU, and paid out. A predetermined prize ball is paid out by operating the prize ball payout motor via the relay board 63, and is sent to the special symbol control board 67 as an image control command, and the special symbol is sent via the liquid crystal analog board and the liquid crystal inverter board. This is a trigger for changing the special symbol displayed on the display 6.

That is, the special symbol start switch S ₁ is frequently turned on to generate a prize ball, and at the same time, fluctuates the special symbol display 6 to invite the opening of the special winning opening accompanying the big hit. This is particularly important for this type of pachinko game machine of the first kind or pachinko machine of the third kind. However, when the connection is made to the main board 60 via the board relay board 61 described above, the detection information of the game ball is changed to the central control in the main board 60 due to a connection failure in the board relay board 61 or the like. In some cases, the input is not made to the device CPU, and in this case, a trouble occurs between the game arcade and the player. Therefore, this special In the symbol start switch S ₁ so as to connect directly to the main board 60, so as to avoid problems on the wiring due to the relay, thereby those that allow proper game control on board It is.

As described above, not all the detection switches controlled by the game balls are connected to the board relay board, but are important data in the game control on the board, and closely connected to the player's gain on the game board. The special symbol starting switch for generating data related to the above is connected directly to the main board even if the wiring advantage is lost.

As a detection switch directly connected to the main board 60, in addition to the special symbol start switch S _1, a configuration in which an ordinary symbol start switch S ₂ is directly connected to the main board 60 may be proposed.

Each of the above-described configurations relates to a so-called pachinko gaming machine in which a special winning opening is opened by a combination of big hits, but a right is generated when the symbol display is in a predetermined combination. When a game ball passes through the special operation area, it is applied to a so-called three-type pachinko game machine in which a series of jackpot operations are performed continuously as a big hit.

In addition, two types of pachinko machines are provided with a normal prize area and a specific prize area in the peripheral wall, and a prize port is provided on the peripheral wall, and when a game ball passes through the starting port, the prize port is opened. Even in a gaming machine, the detection switch provided at the starting port may be directly connected to the main board 60.

On the other hand, the above-described switch directly connected to the main board 60 is an important switch that governs the game and is closely related to the interests of the player. If an on / off signal is not properly output or a malfunction such as a signal is not properly detected due to a control trouble in the main board, an abnormal indication is promptly displayed. It is necessary to take measures such as stopping the game. Therefore, such an abnormality notification unit may be provided.

As this notifying means, as shown in FIG. 5, using a display function of a special symbol display 6 composed of a liquid crystal, a dot matrix or the like, a series of demonstration display symbols for displaying abnormalities are displayed. x can be displayed. In this pattern, a corresponding display such as "Please call a clerk" is displayed together with the "E RROR" display to inform the player that an abnormality has occurred, and to inform the corresponding method. .

As described above, when the display function of the special symbol display device 6 is used as the notification means, there is an advantage that the abnormality notification can be performed together with much information without providing a new notification mechanism. .

Here, after about 2 seconds due to the occurrence of an abnormality, the above-mentioned demonstration display symbol x 2 is dynamically displayed for about 2.5 seconds, and then the right symbol is continuously displayed. In addition to this notification, the function of each winning opening and the display device is stopped.

In this configuration, since the important switches that lead to such display and function stoppage are directly connected to the main board 60, for example, a game as it is often performed through a relay board The display of the demonstration display pattern x and the stop of the function may be executed due to misrecognition due to the trouble of other non-essential functions such that there is no direct problem in the game even if the game is continued. It is avoided, and the reliability of the notification itself increases.
