The game ball 4 thus fired is given a change in the falling direction by a game nail (not shown) or the like arranged on the game board surface 1, and a certain game ball 4 enters the winning openings 5 and 6. , A certain game ball 4 is guided to a special symbol display device starting opening (hereinafter referred to as starting opening) 7. The game balls that have not won any of the winning openings are collected as out balls at the out-ball collecting opening 12 provided at the bottom of the game board surface 1. And
When the game ball 4 wins, per prize ball (1 unit), for example, 13 game balls 4 are paid out as prize balls from the prize ball payout outlet 26.

At this time, when the game ball 4 wins the starting opening 7, a prize ball is obtained in the same manner as described above, and a special symbol display device (hereinafter referred to as a display) of the display unit 30 arranged substantially in the center of the game board surface 1. The device 13 is started. In this embodiment, an electronic slot machine type first-class special electric auditors game machine using three 7-segment LEDs is used, and when a predetermined number, for example, 7 is tripled, a special game state is established, and a solenoid. When 19 is excited and the rod 19b is pulled up, the special winning opening lid 20a of the special winning opening unit 20 provided below the display unit 30 is opened for a certain period of time, for example, 30 seconds, and the winning of the game ball 4 is remarkable. It becomes an easy state, that is, a special game state, and an opportunity to obtain a large amount of prize balls is created. Then, when the continuous winning accessory starting port 9 is won in the opening of the special winning palate 20a,
From that point, it is possible to open continuously for up to 15 times for another 30 seconds, giving an opportunity to obtain a larger amount of prize balls.

However, in this embodiment, in order to prevent the game balls 4 from being cut off at this point, a structure is introduced in which an appropriate unit, for example, 5 units of 65 game balls 4 is paid in advance. According to this, at the same time when a special game state occurs, the five game balls 4 visually observed through the display window 25 are collected in the pachinko gaming machine, and the 65 game balls 4 are collected.
Is paid out from the prize ball payout exit 26 as advance payment.

In addition, in the pachinko gaming machine of this embodiment, in order to ensure fairness of the game, the prepaid game ball 4 is offset by the prize ball paid out by the prize of the game ball 4 in a special game state immediately after that. It is configured to pay back. or,
In order to inform the player of such a state, the game board surface 1
At an appropriate position, for example, near the upper right of the game board surface 1, the game ball 4

Jumps over the gap between the slope 27 and the saucer 23, and
Guided by 3. On the other hand, the game ball 4 that has won the continuous winning accessory starting port 9 in the opening of the special winning opening lid 20a is guided to the saucer 23 in the same manner as above after the winning is detected by the continuous winning accessory starting sensor 9a.

In this case, when the above-mentioned flow path plate 22 is formed, the winning detection opening 21 is provided so that the game ball 4 can easily roll.
It is preferable to have a gradual inclination toward the side, specifically, about 3 to 5 degrees. Further, the saucer 23 is slightly on the right side (the rod connecting portion 23a side) in FIG.
This saucer 2 can be installed diagonally below about 0.5 mm.
The game ball 4 held in 3 naturally shifts to the right side, and there is always a gap on the left side to receive the game ball 4. Then, when the number of the game balls 4 becomes 5, this gap disappears, and the sixth and subsequent game balls 4 that try to enter the saucer 23 are repelled by the game balls 4 of the saucer 23, that is, overflow from the saucer 23, It falls below the gap between the slope 27 and the tray 23 and is collected.

In addition to the one shown in this embodiment, the holding mechanism for the game ball 4 may be a saucer that opens downwards as shown in FIG. According to this, the pans 40, 41 rotatably arranged at appropriate positions
Is a rod 42 when a solenoid (not shown) is excited.
Is pulled to the right, and the rod 43 via a link mechanism (not shown) is pulled to the left, so that the pans 40, 41 are
Is rotated in the direction of the arrow to release the holding of the game ball 4. Then, when the excitation of the solenoid (not shown) is released and the game ball 4 is returned to the holdable state again, the game ball 4 won at the special winning opening 8 or the continuous accessory starting opening 9 is changed to 5
Up to five pieces are held, and those exceeding five pieces overflow from the trays 40 and 41 and fall downward in the pachinko gaming machine.

Further, as shown in FIG. 6, an opening / closing door 46 having a rod 47 interlocking with a solenoid (not shown) is provided at one end of a pan 45 fixed at an angle of about 20 to 30 degrees. You can In this configuration, when the solenoid (not shown) is excited, the rod 47 is pulled upward, the opening / closing door 46 is opened in conjunction with this, and the game ball 4 falls downward. This configuration can also return to the holdable state after the excitation of the solenoid (not shown) is released, and similarly to the above, the game ball 4 won at the special winning opening 8 or the continuous accessory starting opening 9 Up to 5 pieces are held, and those exceeding 5 pieces overflow from the pan 45 and fall downward in the pachinko gaming machine.

In addition, the pachinko gaming machine of the present invention can use various types of holding devices (not shown), and the number of holding devices can be changed appropriately. Therefore, these can be appropriately selected according to the embodiment. is there. In addition, such a game ball holding device, especially when opening or continuous opening after stopping, when the specified number of game balls are not held in the saucer,
The clerk shall supply each time. In addition to the above, it goes without saying that the game ball can be controlled only by software described later without providing such a game ball holding mechanism.

Next, the hardware configuration of this embodiment will be described. FIG. 9 is a block diagram showing a control system for performing a series of operations of the pachinko gaming machine, and in the present embodiment, in order to have versatility, that is, the first-class special electric auditors game machine and the first A single-board printed circuit board with a configuration that uses a microprocessor for the control system so that it can be diverted to various types of game machines, such as the second-class special electric auditors game machine or the third-class special electric auditors game machine. 32 is small. Explaining the configuration of the printed circuit board 32 in detail,
The central processing unit (CPU) 321 is centered on the interface LSIs 324 and 325, and a read-only memory (R) that is firmware in which a control program is written.
OM) 322 and a freely readable / writable memory (RAM) 323 used as a work area of the CPU 321.
Also, it is composed of various counters and drivers.

Here, the interface LSI 324,
325 is used separately for the input system and the output system, the interface LSI 324 is used for the input system, and the interface LSI 325 is used for the output system. According to this, the interface LSI 324 has a function of receiving the prize-winning detection pulse sent from the big prize-winning detection sensor 8a and the continuous winning object starting sensor 9a provided in the big-win prize hole unit 20, and transmitting it to the CPU 321. There is. In this case, the winning detection pulse sent from the winning detection sensor 7a provided in the starting opening 7 is sent to the winning ball counter 326 for paying out the prize ball, and the special symbol display device starting using the up-down counter is started. Sphere counter (hereinafter,
It is sent to a special display start counter (327) and is stored in memory for a maximum of four times, for example, and the number of times the display device 13 can be started is notified to the player using the LED display 16. Then, each time the display device 13 is started, the value of the special display start counter 327 is subtracted by receiving the subtraction pulse from the CPU 321 via the interface LSI 324, and the display of the LED display 16 is changed. Although the upper limit of the number of times of memory is set to 4 in the present embodiment, it can be changed within a range allowed by the social convention at the time of implementation, and the upper limit of the special display start counter 327 is set by the TTL gate circuit. However, it is of course possible to perform these processes on software.

On the other hand, the interface L used for the output system
The following are connected to SI325. that is,
A lamp that informs the player of a special gaming state 1
A driver 328 for driving 1 and a sound generator / amplifier 329 connected to the speaker 15 for producing a sound effect for exciting the player's interest in such a state, and a 7-segment LED for various displays such as special symbols
13 and 14 decoders and 7 segment drivers 330,
331, solenoids 19 and 24 for driving various movable parts
Drivers 332, 333, the solenoid 17 of the prize ball payout mechanism, and the lamp 1 notifying that the prize ball has been paid out.
The winning ball counter 326 and the like control the driver 334 that drives 0.

The pachinko game machine of the present embodiment performs the operation based on the flowcharts shown in FIGS. 7 and 8 by the hardware thus constructed and the software written in the ROM 322. In this case,
8 shows a flow of operations in a normal state of this pachinko gaming machine, and FIG. 8 shows operations of this pachinko gaming machine in a special gaming state, that is, in a state in which 7 are consecutively arranged on the display device 13. It shows the flow.

According to this, when the power of the pachinko gaming machine is turned on, the CPU 3 outputs a reset pulse by the CPU 321.
Not only registers in 21 but also interface L
SI324, 325, RAM323, winning ball counter 3
26 and the special display start counter 327 are reset respectively. As a result, i = 0, j = 0, k = 0, l = 0, n
= 0, t = 0, and so on. From this point, the winning ball counter 326 constantly scans the winning detection sensors 5a and 6a provided in the winning openings 5 and 6,
Further, the special display start counter 327 constantly scans the winning detection sensor 7a provided in the starting opening 7 as in the above, and unless a detection pulse comes from these winning detection sensors 5a, 6a and 7a, a game ball. It is judged that there is no 4 prize.

At this time, when the game ball 4 wins the winning openings 5 and 6, detection pulses are sent from the winning detection sensors 5a and 6a, and the contents of the winning ball counter 326 are added. That is, the value of the winning ball counter 326 is 0 after the reset, so if one gaming ball 4 wins the winning openings 5 and 6, k = k.
Since the value is +1, the value k of the winning ball counter 326 is 1, and if one game ball 4 is subsequently won, k = k + 1 and the value of k is 2. The prize ball counter 326 is a prize ball payout mechanism (not shown).
The prize ball payout pulse is sent to the driver 334 for driving the solenoid 17 and the prize ball is paid out, and the driver 334 sends a subtraction pulse to the prize ball counter 326 until the value of the prize ball counter 326 becomes zero. The prize balls are paid out. That is, now, the winning ball counter 32
If the value k of 6 is 2, the prize ball is paid out once, and the winning ball counter 326 receives the subtraction pulse from the driver 334, so that k = k−1, and thus the value of k becomes 1.
When the prize ball is paid out again and the winning ball counter 326 receives the subtraction pulse, k = k−1, the value of k becomes 0, and the payout of the prize ball is stopped.

On the other hand, when the game ball 4 wins the starting opening 7 at this time, the above-described operation is performed, and the winning detection pulse is also sent to the special display starting counter 327 to add the content value to the display device. The number of possible start times of 13 is displayed on the LED display 16. According to this, since the initial value of the special display starting counter 327 is 0 as in the above case, if one gaming ball 4 wins in the starting opening 7, it is set to l = l + 1. Therefore, the value of the special display starting counter 327. l becomes 1 and LE
One LED of the D display 16 lights up. Then game ball 4
If one wins in the starting opening 7, then 1 = 1 and the value of l becomes 2, and two LEDs of the LED indicator 16 are lit. And this special display start counter 3
The value l of 27 is transmitted to the CPU 321 via the interface LSI 324 to start the display device 13, and then receives a subtraction pulse from the CPU 321 via the interface LSI 324 to perform a process of l = l−1 to perform LED display. One LED of the container 16 goes out. In the present embodiment, as described above, memory is stored with an upper limit of four, so until the value of the special display start counter 327 becomes 0,
That is, the above operation is repeated until all the LEDs of the LED indicator 16 are extinguished. The winning detection sensors 5a, 6a, 7a, 8a and 9a described above are
Although a TTL level signal is produced by using a micro switch, it can be similarly configured by using other detecting means such as a photo sensor.

In the above description, if the display 7 of the display device 13 is tripled, it means that the player can remarkably easily win the game ball 4, that is, a special game state. At this time, the CPU 321 uses the interface LS
A special winning opening pulse is sent to the driver 332 of the solenoid 19 via I325, and the solenoid 19 is excited to open the special winning opening lid 20a provided in the special winning opening unit 20 for a predetermined time, for example, 30 seconds. Let In this case, this driver 332 is provided with a flip-flop circuit at the input, and holds the excitation of the solenoid 19 until the special winning opening closing pulse is received from the CPU 321, and receives the special winning opening closing pulse. When the solenoid 19 is de-energized, the spring 19a is elastically actuated to close the special winning palate 20a.

In this embodiment, when 7 is tripled on the display of the display device 13 as described above, the CPU 321 detects that the game state is a special game state and the interface L
A prize ball payout pulse is sent to the winning ball counter 326 via SI 325, and as described above, for example, the 65 spheres 4 are prepaid. In this operation, the CPU 321 artificially creates a prize winning detection pulse, and in the present embodiment, five pseudo prize winning detection pulses are generated.
It is realized by sending to. At the same time, CPU3
21 sends a hold release pulse to the driver 333 of the solenoid 24 for releasing hold of the game ball, and visually checks it through an appropriate position on the game board surface 1, for example, a display window 25 provided near the bottom of the special winning opening unit 20. The reserved game balls 4 are collected in the pachinko gaming machine so that the number of prepaid game balls 4 is displayed on the prepaid game ball balance display 312.

According to this, at the time when the game sphere is prepaid, the CPU 321 indicates the number of the prepaid game balls 4 by i.
And the interface LSI 325
The number i of the prepaid game balls 4 is transmitted to the prepaid game ball balance display unit 31 via the prepaid game ball balance display unit 3 by the decoder / seven segment driver 311.
It is displayed at 12. In this embodiment, since 65 game balls 4 have been prepaid as described above, i = 65 is set, and 65 is also displayed on the prepaid game ball balance display 312. At this time, in the present embodiment, the following means are used to offset in order to maintain the fairness of the game. This is a detection pulse sent from each of the prize detection sensors 8a and 9a provided at the big winning opening 8 or the continuous winning accessory starting opening 9, respectively. Using the method of subtraction, that is, i = i-13, to display the current balance on the prepaid gaming sphere balance display 312,
The prize balls are not paid out unless the condition of i = 0 is satisfied. Specifically, every time i ≧ 1 is determined, the CPU 321 sends a subtraction pulse to the winning ball counter 326 via the interface 325, and k = k−1.
By doing so, the payout of prize balls is stopped up to five prize balls, and the advance payment is offset.

Further, the handling of the prize balls by the winning balls as described above is as follows. The winning detection pulses sent from the winning detection sensors 8a and 9a are used for the above-mentioned subtraction of the variable i, and the CPU 3 via the interface 324.
By counting by 21, it is treated as a variable j. As a result, after performing the conditional branch of i = 0,
That is, when the condition for paying out the prize ball is satisfied, by sending the number of pulses corresponding to the value of j to the winning ball counter 326, k = k + j is added to add the value of k and the prize ball is paid out. It is carried out.

By the way, in order to prevent the player from being extremely enthusiastic about the special game state due to the opening of the special winning palate 20a, the following restrictions are set on the software. First, the opening time for one time of the special winning opening lid 20a is set so as not to exceed 30 seconds, and during the opening of the special winning opening lid 20a, the special winning opening 8 and the continuous accessory starting opening 9 are set.
As soon as approximately 10 game balls 4 are won, the special winning opening lid 20a is set to be closed immediately. In addition, the continuous opening of the big winning opening lid 20a due to the winning of the continuous accessory starting port 9 is 1
It is set not to exceed 6 times.

This will be described below with reference to FIG. That is, the CPU 321 in a special game state
Sets the time limit t from when a pulse for opening the special winning palate 20a is sent to the driver 332 of the solenoid 19 via the interface LSI 325. From this time, t is subtracted from moment to moment, and when t ≦ 0, the CPU 321 again controls the interface LSI 32.
A pulse for closing the special winning palate 20a is sent to the driver 332 of the solenoid 19 via the switch 5.
In addition, in the game ball 4 that has won the special winning opening 8 in the opening of the special winning palate 20a, the CPU 321 causes the interface LSI 3 to receive the winning detection pulse sent from the winning detection sensor 8a.
By receiving via 24, all are counted by the value of j, and when the condition of j ≧ 10 is satisfied, the CPU 3
21 sends a pulse for closing the special winning palate 20a to the driver 332 of the solenoid 19 via the interface LSI 325. On the other hand, when the continuous winning object starting opening 9 is won during the opening of the special winning opening lid 20a, the CPU 321 sets a new value of t, and from this time, the special winning opening lid 20a is opened again for 30 seconds. Moreover, in this case, the CPU 321
Counts the number of winnings of the continuous accessory starting port 9 as a variable n using the detection pulse of the winning detection sensor 9a, and n ≧ 1.
When the number reaches 4, that is, at the end of the 15th continuous opening, the CPU 321 sends a pulse for closing the special winning palate 20a to the driver 332 of the solenoid 19 via the interface LSI 325. In this way, j
If any of ≧ 10, t ≦ 0, or n ≧ 14 is satisfied, the special winning palate 20a is closed.

However, such a restriction is set in consideration of the social conventions at the time of implementation, and it is of course possible to set other restrictions. Further, in this embodiment,
Although these restrictions are processed by software, they can be processed by hardware.

The pachinko gaming machine of the present embodiment thus constructed has the following actions and effects.
That is, when a special game state is entered, the CPU detects this and pays the game ball in advance, so that the player can concentrate on the game without worrying about running out of the ball, and the special game state is effective. The opportunity to utilize it was secured. And in this case, release the holding of the game ball provided on the game board surface,
By providing a mechanism for collecting the game balls in the pachinko gaming machine and displaying the balance of the prepaid game balls, the interest of the player is improved. Moreover, the game ball paid in advance is offset immediately after that to maintain the fairness of the game. In addition, the control system uses a one-board computer, and the winning ball is detected by connecting the winning detection sensor provided near the winning opening directly to the prize ball payout mechanism, so that the burden on the CPU is reduced. The payout of prize balls can be done quickly. With such a configuration, with a slight software change, not only the first class special electric auditors game machine, but also the second class special electric auditors game machine and the third class special electric auditors game machine etc. Can be diverted to the game machine.

【The invention's effect】

As is apparent from the above description, according to the present invention, when a special game state is entered, an appropriate number of game balls are immediately prepaid, so that the player can play in the special game state. Freed from the fear of running out of balls, I can now concentrate on playing games. In addition, the advance payment of such a game ball gives the player an opportunity to maximize the use of a special game state, so that the interest in the game can be improved, and as a result, the profit of the pachinko parlor can be improved. It can be improved.
