DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine provided with a symbol display comprising a plurality of symbol display units.

[0002]

2. Description of the Related Art When a game ball passes through a starting gate provided with a ball detecting device, the symbol is constituted by a plurality of symbol display portions for variably displaying various predetermined symbols, and based on a ball detection signal from the ball detecting device. Each symbol display unit starts a symbol change, stops and displays a symbol of various combinations, and when each stopped symbol of the symbol display is a predetermined combination, the player Various pachinko machines have been proposed which produce a certain advantageous operation. As this profitable operation, a device that activates a condition device for opening a predetermined special winning opening (so-called three-sling pachinko machine) or a device that directly opens the special winning opening (so-called one-sling pachinko machine) ).

[0003]

In the case of a pachinko machine in which it is determined whether or not a big hit is made based on the result of symbol combination, a model whose symbol fluctuates more frequently than the number of balls struck on the board. However, it is generally preferred by players.

On the other hand, in a configuration using a starting winning port for generating a symbol display in accordance with the winning, the number of symbol fluctuations and a base value (awarded prize with respect to the number of balls hit in a predetermined time). Ball count) is closely related to
As the number of symbol changes increases, the base value also increases, and the turnover rate of customers decreases. For this reason, in order to obtain a predetermined base value, there is no other way but to limit the number of winnings to the starting winning opening by adjusting the nail, and accordingly, the number of symbol changes decreases,
You will buy the disappointment of the player.

[0005] Therefore, pachinko machines employing start gates that do not generate winning balls that can improve the number of times of changing the symbol regardless of the base value are increasing.

However, in such a configuration, the base value is extremely high even if the symbol fluctuates frequently by adjusting the nail so that the ball passing through the starting gate does not enter the general winning opening. And a betting situation occurs where the hit ball is quickly lost.

[0007] Such a situation raises the expectation of a big hit and keeps the player anchored to the pachinko machine, and actually gives the player a painful blow. It is against the ideal form of play,
It's not good for the players, nor for the pachinko industry.

In view of such a situation, the applicant of the present invention has provided a sorting device in Japanese Patent Application No. 5-346532 in a passage leading from a starting gate to a winning opening, and a prize is won after passing through the starting gate. He proposed a configuration that would improve the opportunity.

However, such a means requires that the sorting device be disposed immediately below the starting gate.
It cannot be said that the arrangement design is limited and can be applied to any model.

An object of the present invention is to provide a pachinko machine having a configuration having a starting gate without a prize, and having a configuration capable of drastically correcting the above-mentioned problems.

[0011]

According to the present invention, a prize-ball detecting sensor is disposed in a general prize port which is disposed downstream of a starting gate and in which a passing ball from the starting gate may win. At the same time, when the unit progress value has expired, the ratio of the number of passing balls to the starting gate detected by the passing ball detection sensor and the number of winning balls to the general winning opening detected by the winning ball detection sensor is calculated. It is provided with calculating means for calculating and comparing with a predetermined limit ratio, and notifying means for notifying an abnormality when the calculated ratio is lower than the limit ratio.

In this case, the number of passing balls to the starting gate and
The ratio with the total number of prize balls generated by the winning of the general winning opening detected by the prize ball detecting sensor may be calculated, and an abnormality may be notified when the ratio falls below the limit ratio. Such a configuration is useful when the number of prize balls generated according to the winning in each of the general winning openings is different.

By the way, as the unit progress value, a unit set time for re-starting when the time limit expires can be used. That is, after a predetermined time has elapsed, the ratio of the number of passing balls to the starting gate accumulated during that time and the number of winning balls to the general winning opening may be calculated and compared with the limit ratio. Then, after this calculation, the time limit will re-start.

Further, as the unit progress value, the number of unit ball passes to the starting gate which re-starts upon completion of counting may be used. In this case, the calculation and comparison are performed when, for example, 50 vehicles have passed the starting gate.

In addition, it is also possible to use the total number of hit balls as the unit progress value, and to calculate and compare when a predetermined number is hit.

[0016]

In the above construction, if a predetermined percentage of the balls passing through the starting gate do not enter the downstream general winning opening at the time when the unit progress value has expired, it is regarded as abnormal and notified. . This notification is not only for notification to the game hall,
A configuration for notifying the player is also proposed. Along with this notification, necessary measures such as stopping the game are automatically or manually performed, for example, by providing a game interrupting means and operating it.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 is a front view of a game board 1 of a pachinko machine surrounded by a guide rail 2, and a ball tray and a rotary handle for shooting balls are provided at a lower portion (not shown) of the pachinko machine. Can be A center case 3 fixed to the front of a mounting case (not shown) is disposed in the center of the board of the game board 1, and three symbol display portions A, B, and C are provided in the center case 3. Are arranged in the horizontal direction, and a symbol display 4 composed of a dot matrix display or a liquid crystal display is provided.

At the lower part of the center case 3, there is provided a standby memory lamp array (not shown) composed of four gate passing memory number display LEDs (see FIG. 5).

Further, under the center case 3, a ball provided with a passing ball detecting sensor S ₁ (see FIG. 5) constituted by a photoelectric switch, a limit switch and the like is passed downward to start the game without generating a winning. A gate 5 is provided. If this start gate 5 game ball sphere detection signal is generated from the passing ball detection sensor S ₁ through, symbol display device 4 is driven. The starting gate 5 only passes the ball downward, and does not generate a winning.

At the exit of the starting gate 5, as shown in an enlarged manner in FIG. 2, a vertical row of nails is provided to form flow paths 6, 6 on the left and right. A general winning opening 7 having a built-in winning ball detection sensor S ₂ (see FIG. 5) is provided immediately below the starting gate 5. Three nails 9a, 9a, 9b arranged in a triangle are driven into the entrance of this Q7, and the entrances 8, 8 are formed on both sides between the nails 9a, 9b, and the above-described flow paths 6, 6 are formed. To give the ball falling from the flow path 6 a chance of winning.

On the other hand, a winning opening opening / closing device 10 is provided in the upper right portion of the center case 3 as shown in an enlarged manner in FIG. The winning opening / closing device 10 has a closed position for blocking the special winning opening 11 when the pair of opening / closing wings 12 and 12 is closed, and a special winning opening 11 when the opening / closing wing pair 12 and 12 stand up. It is normally controlled to be converted to an open position for guiding a ball by a solenoid for electric accessory (see FIG. 5). The winning opening / closing device 10 is opened when the symbol display 4 hits and displays.

An electric accessory 17 is disposed below the special winning opening 11. The electric accessory 17 includes a rotating body 18 driven by a motor having six holes formed in a peripheral portion, an operating hole 19 and a lower passage 20.
In response to the detection of the ball by the winning detection switch 21 disposed in the above, it is possible to rotate rightward by one hole and sequentially store the winning balls in the hole, and when three game balls are detected, Alternatively, when the opening operation of the special winning opening 11 by the winning opening opening / closing device 10 is completed, the rotation is always switched to one. And each of them is a winning ball. Then, the ball is supplied to the operation hole 19 to be in a special operation state.

A lower accessory 30 is disposed below the electric accessory 17 as shown in an enlarged manner in FIG. On the upper part of the lower part 30 is provided a rotary chuck 31 having a hole for one ball formed in a peripheral portion. In the special operation state, the ball flows into the hole of the rotary chuck 31, When the ball is supplied to the chucker passage hole 32 with the rotation of the rotation 31, the opening / closing wing piece 41 of the electric accessory 40 integrally formed with the rotation chucker 31 is opened for 9.6 seconds (solid line position). When about 10 balls have flowed into the electric accessory 40, the opening operation ends even during the opening operation. When 16 game balls have won the rotating chucker 31, the special operation state ends.

Next, the operation of the symbol display 4 will be described.

[0026] Each symbol display unit A~C, when a game ball enters start gate 5 spheres detection signal from passing ball detection sensor S ₁ through occurs, drives the symbol display device 4, according to a series of cyclic symbol row The display is sequentially changed.

In this configuration, when a game ball is hit on the game board 1 and passes through the starting gate 5, a lottery is selected from the internal random numbers stored in the storage ROM connected to the central control CPU shown in FIG. And determine the hit or loss. Then, by determining the loss, the value at each time point is selected from the internal hit symbol random number or the internal loss symbol random number stored in the storage device ROM, and each symbol display section A, B, The stop symbol of C is determined.

On the other hand, when the symbols on the symbol display section A and the symbol display section B match, a so-called reach state is established. In the case of the reach state, various fluctuation stop modes different from other stop modes are generated. In the case of a hit, the same symbol as the symbol display portions A and B appears on the symbol display portion C, and in the case of a loss, another symbol appears. In the case of a win, the winning opening / closing device 10 performs a predetermined opening operation as described above, and the above-described winning operation is executed.

Next, the main part of the present invention will be described with reference to the flowchart of FIG.

In the central control unit MPU, a unit set time T (unit progress value) is set in advance by a control program. The unit set time T is assumed to be 1 minute to 1 hour, and about 10 minutes to 30 minutes is considered to be practically appropriate. Further, the limit ratio of the number of passing balls of the starting gate 5 and the number of winning balls of the general winning opening 7 is also designated by the control program and stored in the storage device RAM. This limit ratio is a numerical value that determines whether the game can be continued or not.
It is determined by planning the limit state of the game continuation. For example, the limit ratio is, for example, 10%.

Then, the time period starts (t is the current elapsed time in the figure), and as the game progresses, the passing ball detecting sensor S _{1 of the} starting gate 5 and the winning ball detecting sensor S of the general winning opening 7 are provided. The ball detection signal from ₂ is sent to the central control unit MPU
Is stored in the storage device RAM connected to the central control unit MPU based on the detection signals from the sensors S ₁ and S ₂ , based on the number of passing balls of the starting gate 5 and the number of winning balls of the general winning opening 7. Are integrated respectively. Then, when the current elapsed time t has passed the unit set time T specified in advance, the central control unit MPU calculates the ratio between the number of passing balls of the starting gate 5 and the number of winning balls of the general winning opening 7.

The progress of the current elapsed time t may proceed on the premise that the touch sensor of the steering wheel is turned on or the firing motor is driven. However, during the absence of a player, any of the number of prize balls passing through the starting gate 5 and the general prize port 7 becomes zero and the calculation ratio becomes infinite, so that such a case is excluded. By performing the program control, it is possible to omit such a person detecting means.

After the above-mentioned unit progress value has elapsed, the calculation ratio is compared with the limit ratio. If the calculation ratio does not fall below the limit ratio, it is determined that the operation ratio is normal. The information is temporarily erased, the time limit is started, and the storage and accumulation are performed again.

When the calculation ratio is lower than the limit ratio, the notification means notifies the game hall or the player. When the symbol display 4 is constituted by a liquid crystal display, a dot matrix display, or the like, an error message is displayed using the entire surface, or
Various lamps are driven to blink, or a speaker is driven to notify. Further, the information may be displayed on a management monitor of the game arcade.

If an error message is displayed on the game board and the symbol display 4 is not constituted by a liquid crystal display or a dot matrix display, a display capable of displaying a message is separately attached. Alternatively, another existing display (for example, one that normally displays game information such as the number of rounds) may be used.

The game interruption means may be driven together with this notification. As this means, it is possible to propose a configuration in which the game cannot be continued by stopping the launching ball or stopping the launching motor.

In the platform where the game cannot proceed, the nails 9a, 9a and 9b are adjusted after the store is closed, and the ball passing through the starting gate 5 easily enters the entrances 8 and 8 of the general winning opening 7. By adjusting so as to be appropriate, it becomes appropriate.

In the above configuration, the unit progress value is:
Although the unit set time T is used, the unit progress value may be the number of unit ball passes to the starting gate that re-starts when the count is completed. The number of unit spheres passed is 30 or more
An arbitrary number of about 100 can be set. Then, for example, when the passage of 50 pieces to the starting gate 5 is completed, the above calculation and comparison are performed.

Further, a predetermined total number of hit balls may be used as the unit progress value. That is, the calculation and the comparison may be performed when a predetermined number is printed.
