Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention has a plurality of sorting stages, and when a sorting result in each sorting stage is a result of increasing the probability of a game ball flowing into a special winning area, a step-up display is provided. It relates to a pachinko machine designed to perform.

[0002]

2. Description of the Related Art When a game ball passes through a starting area including a starting port, a starting gate and the like provided with a ball detecting device, the ball detecting device is provided with a plurality of symbol display portions for variably displaying various predetermined symbols. Each symbol display unit starts a symbol change based on the ball detection signal from, and is provided with a symbol display device that displays various combinations of symbols by stopping, and each stopped symbol of the symbol display device is a predetermined group. In the case of a combination, a device that generates a predetermined profit is called a single-type pachinko machine or a three-type pachinko machine, and various configurations have been proposed.

[0003]

By the way, each stop symbol displayed on the symbol display device is determined by a symbol control program, and a symbol corresponding to a random value selected at a predetermined timing is terminated by a predetermined variation pattern. It will only be displayed later. And the hit / loss is determined by the content of the random number whose hit random value is set at a predetermined probability.
Problems such as the use of a back ROM and the manipulation of a program to illegally change the frequency of occurrence of hits are continually occurring.

Further, since numerical values selected at different timings from a sequence circulating in a constant cycle are used as the random numbers, the game balls are fired in synchronization with the pulse of the bodily sensation, and the like are disturbed at a constant timing. Unauthorized games, such as making it easier to generate a hit by selecting a numerical value, are also performed.

Further, there is no technical element such as where to hit the game ball, and it becomes possible to estimate whether or not the hit is close only by how many times the design has changed, and the game itself becomes monotonous. ing.

[0006] The reach expression is determined based on the selected random number value. If the hit probability is set to be low, the reach probability is adjusted in order to draw the player's attention to the reach. Frequent reach. For this reason, reach is frequent at the beginning, so it is effective, but eventually it is discovered that it does not hit the reach, and it can not be expected to hit the reach more than expected It is supposed to distrust you.

[0007] These are caused by the fact that everything has been biased toward probability control by random numbers,
It is necessary to revise the result so that the result is different depending on the free movement of the game ball which is the original form of the pachinko machine. However,
Simply adopting a mechanical mechanism instead of probability control using random numbers, and returning to the old state, can only be evaluated as obsolete.

The present invention has been made in view of the above-mentioned conventional situation and has attempted to improve the situation. A major part of the jackpot generation control is performed by mechanical sorting means for sorting game balls step by step. An object of the present invention is to provide a pachinko machine in which a process is displayed on a progress display device so as to heighten a sense of expectation and increase amusement of a game.

[0009]

In the center case 4, a rotating body type sorting device 24 is provided below the clung type sorting device 15.
Are arranged. The rotator-type sorting device 24 includes a rotator 26 that is driven to rotate in the vertical direction by an electric motor 25 disposed on the back side of the board, and a peripheral surface of the rotator 26 receives game balls. One regular concave portion 27a and one special concave portion 27b are arranged at equal intervals. Each of the normal concave portions 27a is formed in a semicircular groove shape, and is capable of discharging game balls to the rear side. Also, special recess 2
7b is formed in a U-shaped long groove shape capable of receiving only one game ball, and the game ball can be discharged to the rear side at the bottom of the groove. A rear wall plate 28 is disposed close to the rear surface of the rotator 26. The rear wall plate 28 has a general winning area 29a corresponding to the respective rotation trajectories of the normal concave portion 27a and the special concave portion 27b. And the special winning area 29b are opened at different positions.

A ball outlet 30 of the ball passage 20 is opened at an upper portion of the rotating body 26 so as to face the peripheral surface of the rotating body 26. The game ball flowing down the ball passage 20 is temporarily stopped on the peripheral surface until one of the three normal recesses 27a and one special recess 27b comes to the ball outlet 30 position by the rotation of the rotating body 26. After flowing into the concave portion that has come, it moves in the circumferential direction with the rotation of the rotating body 26.

The game balls that have flowed into each of the normal concave portions 27a are discharged to a general winning area 29a provided at a position where the rotating body 26 is rotated about 1/3, and the ball passage 3 is used for paying out the prize balls.
1 to a winning ball processing mechanism (not shown). On the other hand, the game ball that has flowed into the special concave portion 27b passes through the general winning region 29a and is discharged to the special winning region 29b provided at a position where the rotating body 26 has rotated about ５. A ball detecting device 33 composed of a photoelectric switch, a limit switch, and the like is disposed in the ball passage 32 connected to the special winning area 29b. The game ball flowing into the passage 32 is detected. By detecting this game ball, "big hit"
Special operation state.

The rotating body type sorting device 24
This constitutes a third mechanical sorting means, and this third mechanical sorting means is a fourth sorting stage (final sorting stage). In addition, the ball detection device 33 of the ball passage 32,
The ball detecting device detects the passage of the selected good game ball at the downstream of the third mechanical sorting means. Further, in the three types of pachinko machines, the special prize area 29b is a special apparatus operation area, and the ball detection device 33 also functions as a special apparatus operation / stop switch.

[0029] Thus, a plurality of first to fourth selection stages are provided, and the selected good game balls selected in the final stage are caused to flow into the special winning region 29b which generates a more advantageous gaming state than the general winning region 29a. The winning mechanism is configured.

Further, the front surface of the rotating body type sorting device 24 is shielded by a shield plate 34 which cannot be seen through.
The selection process by the distribution of the game balls by the rotating body 26 as described above is made invisible to the player. A confirmation passage 35 made of a transparent material that can be seen from the board surface side is provided below the rotary body type sorting device 24 so as to be continuous with the ball passage 32, and a special winning area 29b is provided.
, And the selected game balls as a result of the selection by the rotating body 26 can be visually recognized. The general prize area 29a
A similar confirmation passage may also be provided in the ball passage 31 on the side, so that game balls serving as evidence of “losing” of the selection result may be made visible.

At the right side of the center case 4, a special electric accessory 36 is provided. A three-type starting port 37 is provided on the upper part of the special electric accessory 36.
The game ball that wins 7 is the concave portion 39 of the rotary chuck 38.
And moves with the rotation of the rotary chuck 38 and is discharged to the chucker passage 40. In a ball passage (not shown) leading from the chucker passage 40 to the back surface,
Three types of starting port switches (not shown) are provided. In the special operation state, when the game balls pass through the three kinds of starting port switches, the special winning opening 41 integrally formed with the rotary chucker 38 is opened for 9.5 seconds, during which nine game balls are opened. Flows into the special winning opening 41, the opening operation ends at that time. The opening operation of the special winning opening 41 is continuously performed until twelve game balls pass through the three-type starting opening switch. Also, during the special operation state, the game ball is again operated as a special device start / stop switch by the ball detection device 3.
When the vehicle passes through No. 3, the special operation state ends.

Next, the operation in each selection stage and the step-up effect by the progress display device 6 will be described. In the symbol control means, which is the first selection stage, when the game ball passes through the starting area 8, the four Ls of the normal symbol display device 7
When the normal symbol composed of the ED 7 'starts blinking and the display mode confirmed and displayed after about 9 seconds is a predetermined one, for example, when all four are turned on, it is a hit. Here, the hit probability is set to 1/16. When the ordinary symbol display device 7 is constituted by a 7-segment display, a dot display, or the like, the ordinary symbol consisting of 16 symbols "00" to "15" is changed, for example, "07" is fixedly displayed. If it is done, it may be a hit. The hit by the ordinary symbol is the first step-up approaching the occurrence of the big hit.

The ball receiving area 10 which is the second sorting stage is opened for about 1.5 seconds by the hit of the ordinary symbol, and the game balls won by opening of the ball receiving area 10 are sent to the ball detecting device 14 in the ball passage 13. Is detected by The open time of the ball receiving area 10 is a time during which one or at most two game balls can win. Then, when the game ball wins in the ball receiving area 10, the second step is up.

The game balls that have won the ball receiving area 10 are:
After flowing down the ball passage 13, it flows into the croon-type sorting device 15, which is the third sorting stage, and is sorted by the three sorting holes 17 a, 17 b, and 17 c of the circular receiving portion 16. The probability of occurrence of the selected good game ball by this distribution is 1/3, the game ball falls into the distribution hole 17a, and the ball passage 20
And the rotary sorter 24, which is the fourth sorting stage
When the good game balls flow down toward, the third step up is performed. Here, the selected good game ball flowing down to the rotating body type sorting device 24 is detected by the ball detection device 21 in the ball passage 20, and a step-up effect image is displayed on the progress display device 6 by the ball detection signal from the ball detection device 21. The reach effect image as the mode is displayed.

The game balls that have fallen into the other distribution holes 17b and 17c are detected by the ball detection device 23 in the ball passage 22. On the main board, the number of game balls won by opening the ball receiving area 10 is grasped by storing the number of ball detection signals from the ball detection device 14, and the number of ball detection signals from the ball detection device 14 , Distribution hole 17b,
If the number of ball detection signals from the ball detection device 23 that detects a game ball that has fallen at 17c becomes equal, it is determined that "losing" has been determined at that time.

As reach effect images displayed on the progress display device 6, various reach display modes such as a win-loss type, a reach type, and a completed type can be proposed. The display of the reach effect image can enhance the expectation of the big hit.

As an example of a completed reach display mode, in a poker game of playing cards, five cards are arranged on a screen and are arranged in a table from the left, and are shown as 10, 10, J, Q, and A state in which the royal straight flush is about to be completed is produced as K, and one of the spades A, 2 to 9 is displayed on the last sheet. The selection of the last one symbol is performed based on the selection result in the final selection stage.

That is, the game balls which flow down from the croon-type sorting device 15 to the rotary-type sorting device 24, which is the fourth sorting stage (final sorting stage), are constantly rotated by the electric motor 25 at a speed of 6 rpm. Three regular recesses 27a and one special recess 2 formed on the peripheral surface of the body 26
7b, the general winning area 29a or
It is assigned to one of the special winning areas 29b. The probability of occurrence of the selected good game balls by this distribution is 1/4, and when the game balls are distributed to the special winning area 29b, the final step-up to the big hit is achieved.

As described above, the special recess 2 of the rotating body 26
The game ball that has flowed into the ball 7b is released to the special winning area 29b, and is detected by the ball detection device 33 provided in the ball passage 32. When a ball detection signal is transmitted from the ball detection device 33, it is determined that a "big hit" has occurred, and the reach effect image displayed on the progress display device 6 is set as a hit mode.
That is, in the case of the above-mentioned playing cards, the spade A is displayed on the last card to complete the royal straight flush. After displaying the hit mode, a result display image, which is one mode of the step-up effect image, is displayed. Here, a jackpot message image is displayed as a result display image. In addition, as described above, the ball detection device 3
When the ball detection signal is sent from 3, the special operation state is set,
A game state advantageous to the player occurs. The player needs to collect and hit game balls on the special electric accessory 36 disposed at the right side of the board.

On the other hand, the game ball that has flowed into the normal concave portion 27a of the rotating body 26 is released to the general winning area 29a, but the game ball is not detected, and the ball from the ball detection device 33 is passed when a predetermined time has elapsed. If there is no detection signal, the general winning area 2
It is determined that it has been released to 9a, and "losing" is determined. In this case, the reach effect image displayed on the progress display device 6 is set to a loss mode. That is, in the case of the above-mentioned playing cards, any one of spades 2 to 9 is displayed on the last card. Further, after displaying the loss mode, a message image indicating a loss may be displayed on the progress display device 6 as a result display image.

As described above, the control for determining the "losing" is performed in such a manner that the general prize area 29a is located before the special prize area 29b, and each game ball released to the general prize area 29a and the special prize area 29b is played. If each hit is detected by a different ball detection device and the hit / losing is determined, the display time of the reach effect image displayed during the sorting will be shorter, and if the display time of the reach effect image becomes longer, it will be a "big hit" The result is predicted in order to match the timing of the result display with the timing at which the "big hit" occurs. In addition, thereby, the result display by the image and the end of the sorting are linked. The general prize area 29a
Each of the game balls released to the special winning area 29b may be stopped by a stopper, and may be made to wait for a time required for image display.

The rotator 26 may be rotated at all times, or from the time when a normal symbol is hit by the normal symbol display device 7 to the time when a "big hit" or "losing" is determined in the final sorting stage. Intermittent rotation, in which rotation is started / terminated at a specific timing recognizable on the main board side, may be used.

During the special operation state, when the next game ball passes the ball detection device 33 as a special device operation / stop switch, the special operation state ends. Since continuous passing of game balls by the ball detection device 33 is a great disadvantage for the player, it can be prevented to some extent. The ball receiving area 10 is usually opened only when one or at most two game balls win. Even if two game balls that have won the ball receiving area 10 are continuously sent from the croon-type sorting device 15 to the rotating-body sorting device 24, the rotating body 26
Since the special concave portion 27b always receives only one game ball, two game balls are released to the special winning area 29b and rarely continuously pass through the ball detecting device 33.

Further, the front surface of the rotating body type sorting device 24 is shielded by a shielding plate 34 so that the player cannot visually recognize the sorting process by sorting the game balls in the final sorting stage, so that the progress display is made. The player's interest can be concentrated on the reach effect image displayed on the device 6. Furthermore, the game ball as evidence of the final selection result is passed through the check passage 35 which can be seen from the board side to be visually recognized by the player, so that the player is not suspicious of the selection under the unrecognizable state. Can be ensured.

The sorting process by the rotating body 26 can be provided so as not to cover the front surface of the rotating body type sorting device 24 but can be visually recognized. Focusing attention and displaying the game ball as evidence in the confirmation passage at the same time as displaying the result in the image can produce a more dramatic effect and improve the interest of the game.

In the step-up effect by the progress display device 6, in the above embodiment, when the step-up is performed in the third sorting stage, the reach effect image, which is one mode of the step-up effect image, is displayed. When the final step-up is performed in the fourth selection stage (final selection stage), the result display image, which is one mode of the step-up effect image, is displayed. Not only the fourth sorting stage, but also the first and second
Also, at the time of step-up in the selection stage, step-up effects according to the degree may be sequentially or selectively performed. If the reach effect image, which is one mode of the step-up effect image, is displayed only when step-up is performed in the third sorting stage as in the above embodiment, the display frequency of the effect image is reduced. However, on the other hand, the hit probability in the case where the reach effect image is displayed is 1/4, which is excellent in the psychological effect of giving a sense of expectation.

In the above embodiment, the third sorting stage is constituted by the mechanical sorting means comprising the croon-type sorting device 15, and the fourth sorting stage is constituted by the mechanical sorting device comprising the rotary-type sorting device 24. Alternatively, the third sorting step may be constituted by mechanical sorting means including the rotating body type sorting device 24, and the fourth sorting step may be eliminated. Here, in the above embodiment, the hit probability in the first sorting stage is 1 /
16, the probability of occurrence of good game balls in the third sorting stage is 1/3,
Since the probability of occurrence of a good game ball in the fourth sorting stage is 1/4, the probability of occurrence of a big hit is 1/192 which is the product of these. Therefore, as described above, the third sorting stage is set as the rotating body type sorting device 24, and when the fourth sorting stage is removed, the hit probability in the first sorting stage is set to 1/48.
The probability of occurrence of the selected game ball of the rotating body type sorting device 24 is 1 /
Since it is 4, the jackpot occurrence probability can be set to the same 1/192. By thus eliminating the fourth sorting stage, the sorting time can be shortened and the structure can be simplified.

Further, in the above embodiment, the opening time of the ball receiving area 10 in the second sorting stage is set to about 1.5 seconds. However, if this is changed to about 0.5 seconds, the ball receiving area 10 is won. Since the number of the game balls is one or zero, the selection of the game balls can be performed by the ball receiving area 10.

Further, the progress display device 6 is composed of a plurality of LEDs arranged in a line, and at the time of step-up in each selection stage, a step-up effect is sequentially or selectively performed in a predetermined lighting mode. Is also good.

In the above-described embodiment, the case where the present invention is applied to the three types of pachinko machines has been described. However, the balls from the ball detecting device 33 for detecting the selected good game balls released to the special winning area 29b in the final sorting stage. Depending on the detection signal, 1
By configuring so as to perform the initial opening control of the special winning port in the kind of pachinko machine, it can be applied to the kind of pachinko machine.

[0051]

As described above, the present invention has a plurality of sorting stages, and the selected good game balls selected in the final stage are caused to flow into a special winning region which generates a more advantageous gaming state than the general winning region. In addition, when the selection result at each selection stage is a result that increases the probability of inflow into the special winning area, a step-up effect based on the selection result is sequentially or selectively performed by the progress display device. Therefore, the interest of the pachinko game can be increased by the progress display.

Also, among the plurality of sorting steps, at least a plurality of sorting steps including the final sorting step are constituted by mechanical sorting means for selecting game balls to obtain good game balls, and each mechanical sorting means comprises: The ball detection device for detecting the passing of the selected game ball is provided in the downstream of the means, and the step-up effect image is sequentially or selectively displayed on the progress display device by the ball detection signal from each ball detection device. By doing so, the main part of the jackpot occurrence control can be performed by mechanical sorting means for sorting the game balls step by step, so that various problems caused by controlling the jackpot occurrence probability by random numbers as in the past, namely, In addition, it is possible to solve the illegal change of the jackpot probability by using the back ROM, the illegal game using the bodily sensation device, and other conventional problems, By the display of the effect image, it is possible to achieve the exaltation of expectations.

In particular, in the above-described configuration, this is one mode of the step-up effect image on the progress display device by a ball detection signal from each ball detection device provided downstream of the mechanical sorting means other than the final one. Expectations can be further enhanced by displaying the reach effect images sequentially or selectively.

Further, in the above configuration, at least the mechanical sorting means at the final sorting stage is shielded to make the sorting state invisible, and the game balls flowing into the general winning area and / or the special winning area are removed from the board surface. If the sorting result is provided so as to be visible by passing through the confirmation passage which can be seen from the side, the player is not interested in the sorting state at the final sorting stage, and the player is interested in the step-up effect image. The concentration can be further concentrated, and the game balls as evidence of the selection result can be visually recognized, so that the clearness of the selection can be ensured even when the game balls cannot be visually recognized.
