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 special symbol display device for opening a special winning opening by a predetermined combination and a normal symbol display device.

[0002]

2. Description of the Related Art When a game ball passes through a starting passage provided with a detection switch, the game ball is constituted by a plurality of symbol display portions for variably displaying various predetermined symbols, and based on a ball detection signal from the detection switch. A special symbol display device in which the symbol display unit starts to change and stop to display various combinations of symbols, and a special prize which is opened when each stopped symbol of the special symbol display device is a predetermined combination. Various things with a mouth have been proposed.

[0003] When a game ball passes through the starting path, it starts to fluctuate, stops, stops, and displays various symbols unspecified, and communicates with a winning opening to be converted into an open position and a closed position. There has also been proposed a device provided with a normal variable winning device that is driven to be converted to an open position when the stop symbol of the ordinary symbol display device is a predetermined symbol.

As described above, when a game ball passes through a symbol starting path provided with a detection switch, the symbol is displayed based on a ball detection signal from the detection switch. The display unit is provided with a symbol display device that starts changing, stops and displays various symbols, and when the symbol display unit is a predetermined symbol or a combination of predetermined symbols, a predetermined symbol is displayed on the game board. A variety of pachinko machines have been proposed for producing profitable operation.

[0005]

In the above configuration,
A plurality of different probabilities are set as the hit probabilities of the symbol display device, and a pachinko machine that changes from a low probability to a high probability when a predetermined condition is satisfied has been proposed.

By the way, in such a configuration, conventionally, the display mode and the display probability of the symbol are the same at the time of the low probability and at the time of the high probability, and only the internal probability is changed.

For example, taking a normal symbol display device as an example, the display symbols of the normal symbol display section are "2" and "7".
If "7" is a hit in the two types, the symbol to be displayed when the normal symbol display section stops changing is determined based on the internal ordinary random number tables of "0" to "11". When the probability of the symbol is low, "11" is hit, and when the probability is high, "2" to "11" are hits. In the case of a hit, the symbol in the ordinary symbol display section of the ordinary symbol display device is set to “7”, and when a loss is determined, “2” is set to a stopped symbol. Therefore, in this case, the hit probability on display of the ordinary symbol display device is 1/2, the hit probability on software is 1/12 at low probability and 10/12 at high probability.

[0008] As described above, the proportion of the symbol displayed on the symbol display section occupied by the winning symbol (the ratio of the winning symbol),
In some cases, there is a large disparity in the actual winning probabilities, and as a player, it is psychologically unconvincing and impairs the interest of the game.

An object of the present invention is to solve the above-mentioned problems.

[0010]

According to the present invention, there is provided a pachinko machine equipped with the above-mentioned symbol display device, wherein a ratio of symbols per symbol of the symbol display device when a high probability is selected and a low probability are selected. The first means is that when the high probability is selected, the first symbol is displayed on the same symbol display section when the high probability is selected. A control command means having control contents in which the number is relatively larger than the number of symbols when the low probability is selected is provided. Further, the second means is constituted by arranging a plurality of symbol display unit rows in which the symbol display devices are arranged in a horizontal direction in a vertical direction, and it is a hit when any of the symbol display unit rows is in a predetermined combination. At the same time, when the low probability is selected, the invalid symbol display section row is mechanically or electrically shielded, the unshielded symbol display section row is regarded as valid, and the symbol display section row is a hit in a predetermined combination. It is provided with control command means having the above-described control contents. Still further, the third means, the symbol display device is composed of a plurality of symbol display unit, and when the symbols displayed on each symbol display unit is the same symbol, hits,
When the high probability is selected, any one of the symbol display portions is mechanically or electrically hidden, and control command means having control contents for reducing the number of effective symbol display portions is provided. .

Here, the high probability and the low probability are relative concepts between a plurality of different probabilities. For example, when three types of probabilities are set, the intermediate probability is higher than the lowest probability. Correspondingly, the ratio of the winning symbol of the symbol display device when the intermediate probability is selected is relatively higher than the ratio of the winning symbol when the low probability is selected. Get higher.

[Effect] The operation when two kinds of probabilities are set will be described with reference to a normal symbol display device as an example. When the game ball passes through the starting passage, the symbol display device is usually driven to start and stop each symbol, and displays various symbols or combinations of symbols. Then, when the symbol becomes a predetermined symbol (hit display), the normal variable winning device operates to open the winning opening.

On the other hand, the hit probability of the ordinary symbol display device is determined by a low probability random number table and a high probability random number table. When the predetermined condition is satisfied, the table changes to a high-probability random number table, and the hit probability is improved. In this case, the ratio of winning symbols on each display unit of the ordinary symbol display device is higher than the ratio of winning symbols when the low-probability random number table is selected. Therefore, the hit probability on the surface and the actual hit probability based on the high-probability random number table are close to each other, and the sense of discomfort is eliminated. Note that the same random number table may be used to change the probability, and the number of hit random numbers may be changed.

In the first means, the control for adjusting the winning symbol ratio is performed when the high-probability random number table is selected and the number of winning symbols displayed on the same symbol display unit is determined as follows. This is achieved by making the number of hits relatively larger than the number of hits when the low probability random number table is selected.

[0014] In the second means, the symbol display devices are arranged in a plurality of vertically arranged symbol display unit rows in which the symbol display devices are arranged in a horizontal direction. When the low probability is selected, a part of the symbol display part row is mechanically or electrically shielded, and the effective symbol display part row is clearly recognized. You.

Further, in the third means, the symbol display device comprises a plurality of symbol display portions, and when the symbols displayed on each symbol display portion are the same symbol, the hit is selected, and the high probability is selected. When it is done, one of the symbol display parts is hidden mechanically or electrically, so that the number of effective symbol display parts is reduced, and also in this configuration, the effective symbol display part row is clearly visible. Become.

Above the center case 4, there is provided a normal symbol display device 10 composed of normal symbol display portions A and B made of a dot matrix. The relationship between the display symbols of the ordinary symbol display portions A and B and the hitting loss will be described later. In addition, a standby recording lamp array 11 composed of four pilot lamps is provided below the normal symbol display sections A and B.

On both sides of the center case 4, there are provided ordinary symbol starting gates (ordinary symbol starting passages) 13, 13 provided with detection switches S1 (see FIG. 3) constituted by photoelectric switches, limit switches and the like. When a game ball passes through the ordinary symbol starting gates 13 and 13 and a ball detection signal is generated by the detection switch S1, the ordinary symbol display device 10 is driven by the command of the central control unit MPU via the ordinary symbol display drive circuit. It starts, and the winning or losing symbol is displayed. This ordinary symbol starting gate 1
The prize holes 3 and 13 may be configured as prize holes through which the balls pass in the reverse direction of the game board and become prize balls.

Further, a special symbol starting port (special symbol starting passage) 14a for operating the special symbol displaying device 6 is provided directly below the special symbol displaying device 6. A normal variable winning device 15 is provided beside the special symbol starting port 14a. The normal fluctuation winning device 15 guides a game ball to a winning position by closing the opening and closing wing pieces 16 and 16 and closing the opening and closing wing pieces 16 and 16 in an inverted octagonal shape when the opening and closing wing piece pairs 16 and 16 are standing. Is controlled by a solenoid to change the opening position. The normal fluctuation winning device 15 is driven to open when the normal symbol display device 10 is in a hit display. The winning opening of the normal variable winning device 15 also serves as the special symbol starting opening 14b. Therefore, even if a ball enters the normal variable winning device 15, the special symbol display device 6 is driven.
It is to be noted that an embodiment in which the special symbol starting port 14b is not used as the special symbol starting port and is merely a winning port can be proposed.

The special symbol starting ports 14a, 14
b has a detection switch S2 (see FIG. 3) composed of a photoelectric switch, a limit switch, etc., and generates a predetermined number of prize balls as the game balls pass, similarly to a normal winning opening, Along with the ball detection by the detection switch S2, the special symbol display device 6 is driven via a symbol display drive circuit by a command from the central control unit MPU.

Further below the special symbol display device 6, a special variable winning device 2 having a wide special winning port 23 is provided.
2 are provided. The special fluctuation winning device 22 has a known structure in which the lid 24 is opened in the front-rear direction by a solenoid, and the guiding action of the lid 24 guides the game ball to the special winning opening 23. 23
Is set as a specific area 25, as described later, when a game ball enters the specific area 25, a continuous opening operation is performed.

Next, the operation of the above configuration will be described.

When a game ball is hit on the game board 3 and passes through the ordinary symbol starting gates 13, 13, the ordinary symbol display device 10 starts driving, and starts to fluctuate with a symbol including, for example, "7". Stop in 10 seconds. In the case of “77” or “33”, this is a hit. In this case, the normal fluctuation winning device 15 is opened and the pair of open / close wings 16, 16 is opened for about 5.8 seconds. still,
The contact operation may be a reciprocating opening / closing operation. The passage through the normal symbol start gates 13, 13 is normally suspended up to a maximum of four, and is executed sequentially for each memory digestion. The open normal fluctuation winning device 15 is closed when a predetermined time has elapsed or a predetermined number of winnings have been achieved, as described later.

When the game ball passes backward through the special symbol starting port 14, the special symbol display device 6 is driven together with the supply of the premium ball. In the case of continuous passage, the standby recording lamp array 9 is sequentially turned on and up to four lamps are held.

When the special symbol display device 6 is driven by the passing of the ball to the special symbol starting port 14, the special symbol display portions D, E, and F start to change by the switching control by the symbol display driving circuit, and are changed. When about 8 seconds have elapsed, the change stops in the order of the special symbol display sections D, E, and F. At this time, when the symbols of the special symbol display section D and the special symbol display section E match, the special symbol display section F performs a special operation corresponding to the reach state, such as a low-speed scroll, to increase the player's euphoria. Is increased, the special symbol display section F stops.
At this time, when the special symbol display section F stops at a different symbol, the original symbol state is restored.

On the other hand, the special symbol display portions D, E, and F are, for example, "111", "222", "333", and "444".
In the case of a big hit display such as a pattern consisting of numbers or alphabets being the same, the speaker emits a sound through the sound generator and the amplifier of FIG. 3 and the solenoid of the special variable winning device 22 is driven. The lid 24 is tilted forward to open the special winning opening 23, and either the predetermined number of game balls of 10 winning a prize or the maximum opening time of about 30 seconds is satisfied. Then
The opening operation is temporarily ended. The special winning opening 23 is continuously driven when passing through the specific area 25, and the special winning opening 23 is opened again after the opening operation is completed. The maximum number of consecutive operations is 16 including the initial release.

The symbol variation control of the series of special symbol display devices 6 and the ordinary symbol display device 10 described above can be easily executed by control command means constituted by a microcomputer including the central control unit MPU shown in FIG. .

The central control unit MPU 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. Storage device RO
M stores fixed data such as a control program, a random number table, a big hit game pattern, a display pattern of lamps and LEDs, and a sound generation pattern from a speaker.

In the storage device RAM, the detection switches S1, S1 of the normal symbol starting gates 13a, 13b, the detection switches S2, S2 of the special symbol starting ports 14, 14, the specific area 2 are provided.
5 and a detection signal from a special winning opening 23 of the special variable winning device 22 and a count switch provided in a winning opening of the normal variable winning device 15 or a symbol display portion A. , B, D to F, a storage area for temporarily storing data or the like for determining the stop display mode,
A register area constituting a soft timer and a work area of a microcomputer are provided. Further, an address bus for unilaterally transmitting information designating an address for reading and writing data from the central control unit MPU to the storage device RAM, a central control unit MPU and the storage device RO.
M and RAM are connected to a data bus for exchanging data.

The microcomputer includes a power supply circuit for supplying electricity to the MPU, a voltage detection circuit for transmitting a reset signal via an OR gate when the power supply voltage deviates from an allowable voltage value, an oscillation circuit for generating a clock pulse, A frequency divider that divides the frequency of the clock pulse of the oscillation circuit and sends a reset signal to a reset terminal via an OR gate is connected.

On the input side of the central control unit MPU, detection switches S1, S1 of the normal symbol starting gates 13, 13 and detection switches S2, S2 of the special symbol starting ports 14a, 14b are provided via a waveform shaping circuit for preventing chattering. Also, a V winning switch, a count switch, and the like provided in the specific area 25 are connected, and a signal sent from each switch is waveform-shaped by a waveform shaping circuit and transmitted to the central control unit MPU as input data. .

On the output side of the central control unit MPU, a driver circuit for receiving the output data and driving each of the devices is connected, and the driver circuit includes special symbol display sections D and E of the special symbol display device 6. , F, normal symbol display device 1
The normal symbol display portions A and B of 0, the solenoid of the variable winning device 22, the storage number display LED 11, the windmill lamp, the side lamp, and the like are connected. Furthermore, the central control unit MPU
Is connected to a sound generator that receives sound data and outputs it to an amplifier.

In the control processing procedure (main routine) of the main processing controlled by the microcomputer described above, the ordinary symbol subroutine shown in FIG. 4 is incorporated and executed sequentially.

The storage device ROM usually contains a symbol display device 1.
It has a low-probability random number table that determines a hit probability of 0, and a high-probability random number table. As shown in FIG. 5, a low-probability random number table is normally extracted. A random number table is extracted. This probability fluctuation signal is, for example, when the variable display units D, E, and F of the special fluctuation winning device 22 are aligned at “777”,
Occurs after the end of the jackpot operation. Then, for example, the ON state of the probability variation signal is maintained until the next hit operation occurs. In this case, for example, the hit probability of the high probability random number table is 10/12, and the hit probability of the low probability random number table is 1/12.

The ON operation (high-probability state) of the probability variation signal is not only generated in accordance with the display pattern of the jackpot operation as described above, but also always generated during the jackpot.
Various conditions can be set.

By the way, when the low probability random number table changes to the high probability random number table due to the ON signal of the probability variation signal, the ordinary symbol display device 1
Assuming that the number of displayed symbols and the number of winning symbols in the normal symbol display portions A and B of 0 are the same, the probability on the surface determined by the ratio of the winning symbol to all symbols differs from the actual probability determined by the high-probability random number table. Inconsistency is lost, and a strange hit operation condition occurs.

Therefore, in the present invention, as shown in FIG. 4, symbol control control is performed for each of the random number tables, and the normal symbol display device when the high probability random number table is selected. The ratio of winning symbols on each display section is set higher than the ratio of winning symbols when the low-probability random number table is selected.

Here, according to the first means of the present invention, when the high probability random number table is selected, the number of symbols to be displayed on the same symbol display portion is determined by the low probability random number table. This is achieved by making it relatively larger than the number of symbols per hit. The following configuration is proposed as the control means.

The same symbols are always displayed on the left and right of the normal symbol display portions A and B, and completely different symbols are displayed between the high probability and the low probability. For example, when the probability is low, the display symbols of the normal symbol display portions A and B are set to "0" to "9", the hit symbol is set to "77", and the probability on the surface is set to 1/10. On the other hand, at high probability,
The alphabet is “A” to “J”, and the winning symbol is “big hit” when “A” to “H” are aligned on the left and right, and the probability on the surface is 8/10.

The display symbols of the ordinary symbol display portions A and B are set to “0” to “9”, so that the symbols are displayed separately on the left and right when the probability is low, and the same symbols are displayed on the left and right when the probability is high. To be displayed, for example, "77",
Only when "33" is hit. Therefore, the probability on the surface is 1/50 at low probability and at high probability,
It becomes 1/5. Therefore, if the probability based on the internal random number is 10 times higher than the low probability when the probability is high, the matching of the probability ratio is maintained.

The color of the symbol is changed to increase the number of hit symbols. For example, when the probability is low, green numbers “0” to “9” are displayed, the winning symbol is “7”, and the probability on the surface is 1/10. On the other hand, when the probability is high, red numbers “0” to “9” are displayed, the winning symbol is set to “0” to “7”, and the probability on the surface is set to 8/10. Alternatively, when the probability is high, red numbers “7” to “9” are displayed, and the winning symbol is “7”, and the probability on the surface is ３.
And

Next, an embodiment of the second means of the present invention will be described. As shown in FIG.
Are arranged in the horizontal direction in a pattern display section row 30, 31, 32, and each of the symbol display section rows 30, 31, 32 is composed of three symbol display sections A, B, C, respectively, and Each of the symbol display sections is arranged so as to form a vertical and diagonal arrangement. When the probability is low, only the symbol display section row 30 is valid, and when the three symbols are the same symbol, this is regarded as a hit, and the other symbol display section rows 31 and 32 are invalidated. This is to make it invisible by means such as mechanical shielding, or to incorporate elements that become transparent or cloudy due to a change in voltage, for example, in the display windows of the symbol display rows 31 and 32. Can be achieved electrically. Alternatively, the light may simply be turned off, or an invalid symbol may be displayed. Thereby, it is possible to understand at a glance which effective symbol display section row is.

On the other hand, when the probability is high, the symbol display section row 30,
31 and 32 are all valid. And in this state,
In addition to the horizontal arrangement, the diagonal arrangement or the vertical arrangement is also effective, and a win is made in a state where the symbols of the three symbol display portions in any one of the columns match. Accordingly, the number of hit symbol columns increases.

FIG. 5B shows an ordinary symbol display device 1 by symbol display section rows 33 and 34 comprising two symbol display sections A and B.
0. In this case, when the probability is low, only the symbol display section row 34 is valid, and when the two symbol display sections A and B have the same symbol, this is regarded as a hit, and the other symbol display section row 33 is used. Is invalidated. On the other hand, when the probability is high, all of the symbol display section rows 33 and 34 are valid. In this state, in addition to the horizontal arrangement, the diagonal arrangement and the vertical arrangement are also valid, and a win is made in a state where the symbols of the two symbol display units in any one of the columns match.

Normal symbol display device 1 used in this configuration
0 can correspond to all of liquid crystal, dot matrix, 7 segment, reel and the like.

Next, an embodiment of the third means of the present invention will be described. As shown in FIGS. 6 and 7, the ordinary symbol display device 1
0 is composed of a plurality of symbol display portions A, B, and C. When each symbol is the same symbol, it is a hit, and when the high probability random number table is selected, any symbol display portion is hidden. The number of effective symbol display parts may be reduced.

In this configuration, as shown in FIGS. 6 and 7, three symbol display portions A, B and C are provided in parallel as shown in FIG. The display portion B is retracted to the rear, and the symbol display portions A and C on both sides are moved to the center (see the arrow in FIG. 6) to be adjacent as shown in FIG. 7, and the central symbol display portion B is concealed. You may do it.

In this embodiment, the ordinary symbol display device 1
0 can be constituted by two symbol display portions A and B. For example, in the case of a high probability, one symbol display portion is retracted or hidden behind the other symbol display portion, Only the other may be valid.

As described above, when the special symbol display portions D, E, and F of the special symbol display device 6 have a specific big hit symbol, the special symbol becomes one after another after the end of the big hit operation. Up to, normal symbol display device A, B, C
Is extracted from the high-probability random number table to provide a great benefit to the player. However, if the probability is continuously high as described above, it is often unclear whether the probability is based on the first big hit or the second big hit.

Therefore, in such a case, the display state of the ordinary symbol display device until the next big hit is distinguished from the display style until the next big hit so as to clarify the current high probability state. You may do it. For example, as shown in FIGS. 6 and 7, when three symbol display portions A, B, and C are arranged in a row, they are displayed as they are when the probability is low, and the central symbol is displayed when the probability variation is the first high probability. The portion B is retracted and shielded as described above, and is displayed only on the left and right symbol display portions A and C. Then, at the second high probability variation, the symbol display sections A and C are similarly moved to display only the symbol display section B.

In each of the above configurations, when the symbol display device 10 has a high probability, it is preferable to notify the player by sound effects, lighting of decorative lamps, and the like.

When the probability of the special symbol display device 6 fluctuates, the ratio of winning symbols when the high probability is selected is determined by
Each of the above-described configurations can be applied to increase the ratio of winning symbols when the low probability is selected.

[0054]

According to the present invention, as described above, a plurality of different probabilities are set as the hit probabilities of the symbol display devices 6 and 10, and when a predetermined condition is satisfied, the probability is changed from a low probability to a high probability. In the configuration described above, the control of the control content to make the ratio of the winning symbol of the symbol display device when the high probability is selected relatively higher than the ratio of the winning symbol when the low probability is selected Since the command means is provided, the difference between the actual probability and the probability on the surface is reduced, and a hit operation without a sense of incongruity can be realized. Further, in the first means, by controlling the number of hit symbols displayed on the same symbol display unit, the actual probability and the probability on the surface are adjusted as much as possible. In addition, there is no increase in the number of symbol display sections, and the apparatus is simplified. In the second means and the third means, the invalid symbol display section is mechanically or electrically shielded, so that the effective symbol display section row is clearly visible.
