[0001]
BACKGROUND OF THE INVENTION
The present invention is a game ball that is launched by the launching device and randomly falls along the game board surface by its own weight, and a lottery is executed by winning a start opening provided on the game board surface. The present invention relates to a gaming machine that can be advantageous to a player or a gaming state.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, in gaming machines, particularly pachinko machines, a lottery is made by detecting a pachinko ball that has won a start winning opening (special symbol start winning opening). There are pachinko machines that are opened a predetermined number of times to increase the winning rate of game balls and have a function that makes it advantageous for the player.
[0003]
In this type of pachinko machine, a display unit (usually a liquid crystal display screen) is installed at the center of the gauge board of the pachinko machine as an effect for notifying the player of the result of the lottery. The display unit is configured to display a symbol hit screen in a sequence when a symbol changing screen of a plurality of columns is configured (there is also a background screen) and the changing symbol stops. By seeing the symbol variation screen, the player is amazed whether it is a hit or miss, so that the player can have a sense of expectation.
[0004]
In order to start the lottery, it is an absolute condition that the pachinko ball wins a special symbol start winning opening, and the player launches the pachinko ball aiming at the special finger introduction winning opening.
[0005]
On the other hand, the game board surface is provided with a plurality of nails and windmills, preventing the fall of the pachinko ball, guiding the pachinko ball in an unexpected direction, or blowing it away, improving the game play Yes.
[0006]
A stage is provided above the special start winning opening. This stage is formed as a part of the electric accessory unit provided with a rectangular hole for exposing the symbol variation screen. That is, there is a step between the surface forming the rectangular hole and the surface of the game board, and a portion connecting between the steps is applied as the stage.
[0007]
On this stage, a pachinko ball is placed by bouncing off with the nail or the like. In addition, a pachinko ball may be guided onto the stage through a tunnel called a separate warp road, and may be placed.
[0008]
Since the stage is formed in an arcuate shape (arc shape) with the lowest position directly above the special start prize opening, pachinko balls rolling on the stage fall to the vicinity of the special start prize opening . For this reason, the probability of winning a prize at the special start winning opening increases.
[0009]
In other words, it can be said that the winning probability to the special start winning opening can be predicted to some extent by the shape of this stage.
[0010]
However, the falling direction of the pachinko ball from the stage varies depending on the momentum of the pachinko ball and the rotation (rotation) of the pachinko ball itself, and the winning probability in the design (ie, at the initial stage) and the actual game (ie, running) There may be a gap between the winning probability and
[0011]
In such a case, conventionally, along with the review of the design of the stage shape, there is a great adverse effect on the cost such as time loss of development of the next model and reordering of the mold.
[0012]
As a related technology, as a structure for changing the flow of pachinko spheres, Japanese Patent Publication No. 3-63388 (hereinafter referred to as the prior art) describes that the groove is accommodated in the groove according to the shape of the groove provided in the rotating body. It is disclosed to discharge the pachinko spheres in different directions.
[0013]
More specifically, with respect to the rotating body that rotates in the opposite direction at a predetermined cycle, the inversion cycle is changed at a predetermined timing to change the flow path. Also, different groove shapes are differences in depth.
[0014]
In this prior art, the pachinko ball is accommodated in different grooves at the timing when it reaches the rotating body, and after being accommodated, the purpose is to discharge in a predetermined direction, and the problem of instability of the direction of the pachinko ball Is not a solution.
[0015]
In consideration of the above facts, the present invention makes it possible to change the expansive area that falls from the stage to the vicinity of the special starting prize opening after being installed in the amusement hall or during operation after the installation, and the winning probability to the special starting prize opening It is an object to obtain a gaming machine that can be adjusted to the design probability.
[0016]
According to the first aspect of the present invention, a lottery is executed by winning a game ball that is launched by a launching device and randomly falls along the surface of the game board with its own weight at a start opening provided on the surface of the game board. As a result of the lottery, the gaming machine can be advantageous or in a gaming state, and a gaming ball can be placed in the vicinity of the upper side of the starting port on the gaming board surface while being recessed toward the back with respect to the gaming board surface. And a stage that is curved in an arch shape so that the probability that the game ball that has been placed and dropped from the position immediately above the start opening is high, and a function as a game ball support surface in the vicinity of the position immediately above the start opening in the stage And a guide means for guiding the game ball while changing the spread in the falling direction as appropriate ,
The guide means includes a first recess having a circumferential opening width dimension substantially the same as the diameter of the game ball, and a second recess having a circumferential opening width dimension significantly greater than the diameter of the game ball. , And the peripheral surface including the first and second recesses is sequentially rotated in the vicinity of the stage immediately above the start port. It is characterized by comprising a rotating body applied as a sphere support surface .
[0017]
According to the present invention , as a part of the support surface of the game ball on the stage, the guide means capable of appropriately changing the spread in the falling direction of the game ball is applied. By changing, it is possible to set the winning probability to the special start winning opening to a desired value.
[0019]
A rotating body is employed as the guiding means, and first and second recessed portions having different circumferential width dimensions are provided on the peripheral surface of the rotating body. Since the first recess is substantially the same as the outer diameter of the game ball, the spread angle in the guide direction is narrow, and the game ball can be concentrated in one direction. On the other hand, since the second recessed portion has a wide spread angle, the game ball diffuses slightly. Further, in the case of the arc peripheral surface other than the first and second recessed portions, the spread of the game ball is so large that the falling direction of the game ball can hardly be specified.
[0020]
By combining such a plurality of forms, it becomes easy to adjust the winning probability to the special start winning opening according to the rotating state of the rotating body.
[0021]
It further has a rotation adjusting means for adjusting a rotation state including a rotation speed and a rotation direction of the rotating body.
[0022]
In particular , during the game, by adjusting the rotation state of the rotating body by the rotation adjusting means, it is possible to have game characteristics.
[0023]

That is, in the symbol display control board 160, data of different display contents based on a plurality of types of command signals are stored in advance, and the data is selected based on the command signals and activated.
[0040]
4 to 6 show details of the electric accessory unit 122. FIG. The electric accessory unit 122 is made of synthetic resin, and a rectangular hole 10 through which the display unit 124 is exposed is formed at the center thereof.
[0041]
The display portion 124 is highlighted around the rectangular hole 10 by various decorative parts and decorative shapes. In particular, a translucent decorative member 12 is fitted to the left and right peripheral edges of the rectangular hole 12, and a light source such as a lamp or LED (not shown) is disposed on the back side of the rectangular hole 12 to control lighting and blinking according to the gaming state. It has come to be.
[0042]
As shown in FIG. 5, the upper part of the electric accessory unit 122 protrudes forward of the game board (left side in FIG. 5) with respect to the surface of the gauge part 114, and the uppermost surface falls from above the gauge part 114. The pachinko ball 14 (see FIG. 6) is received, and the guide portion 16 has an arcuate surface that is distributed to the left and right. Further, the guide portion 16 also has a role as a protective member for preventing the pachinko ball 14 from directly contacting the decorative member 18 disposed under the guide portion 16 and the display portion 14 exposed from the rectangular hole 10. Yes.
[0043]
On the other hand, the surface of the electric accessory unit 122 in which the rectangular hole 10 is formed is recessed behind the game board (on the right side in FIG. 5) with respect to the surface of the gauge portion 114. A step is formed between the two.
[0044]
This step is a stage 20 on which the pachinko ball 14 can roll, and is provided along the lower end portion of the rectangular hole 10 and has a downwardly convex circular arc surface whose center is the lowest.
[0045]
On this stage 20, the pachinko ball 14 that falls along the surface of the gauge portion 114 is bounced by a nail, a windmill 118, and the like, guided by the arc surface, and again from the center to the surface of the gauge portion 114 again. It is supposed to be returned.
[0046]
As a result, since the special symbol start winning port 126 is provided below the fall area from the stage 20, the special symbol start winning port 126 becomes easy to enter, and the pachinko ball 14 mounted on the stage 20 is It can be advantageous to the player.
[0047]
Here, a notch 22 is formed in the lowest part (the center in the width direction in FIG. 4) of the stage 20 of the present embodiment. The notch 22 communicates with a circular groove 24 provided in the lower part of the stage 20. A rotating die 26 as a rotating body is accommodated in the circular groove 24. A rotating shaft of the rotating die 26 penetrates the back surface side of the gauge portion 114 and is connected to a rotating shaft of a driving means (motor) (not shown). The rotary die 26 can be rotated in the circular groove 24 by the driving force of the motor.
[0048]
Due to the rotation of the rotary die 26, the peripheral surface of the rotary die 26 is sequentially exposed to the notch 22 and functions as a part of the stage 20. A plurality (two in the present embodiment) of recessed portions 28 and 30 are formed on the peripheral surface of the rotary die 26. The first recessed portion 28 has a circumferential width dimension that is substantially the same as or smaller than the outer diameter of the pachinko ball 14, and receives the pachinko ball 14 that has rolled the stage 20. The movement is suppressed, and the drop direction can be a relatively narrow angle (see θ1 in FIGS. 9 and 13).
[0049]
On the other hand, the second recessed portion 30 has a circumferential width dimension larger than the outer diameter of the pachinko sphere 14, and even if the pachinko sphere 14 rolling the stage 20 is received, the second recess 30 is allowed to swing to some extent and has a relatively wide angle. (See θ2 in FIG. 12 and FIG. 13) is the falling direction (θ1 <θ2).
[0050]
Further, when the portions other than the first and second recessed portions 28 and 30 correspond to the cutout portion 22, there is no restriction on the falling direction of the pachinko ball 14, and therefore a considerably wide angle (see θ3 in FIGS. 6 and 13). The falling direction (θ2 <θ3).
[0051]
In the present embodiment, the rotation state of the rotary die 26 (constant speed rotation, reverse rotation, step drive, etc.) can be set on the pachinko parlor side. For this reason, the advantageous / disadvantageous state (the state of ease of entering the special symbol start winning opening 126) can be temporally changed according to the timing at which the pachinko ball 14 is placed on the stage 20.
[0052]
The operation of this embodiment will be described below.
[0053]
First, when a pachinko ball is launched, it is guided by the rail 112 and falls while making unpredictable movement while abutting against the nail 116, the windmill 118, etc. of the gauge part 114. Here, when winning a prize at the winning opening 120, a predetermined number of pachinko balls are paid out (prize balls). When the normal symbol start winning opening 130 is won, the normal symbol winning sensor 170 detects this.
[0054]
With this detection, the main control board 150 starts drawing a normal symbol. That is, a random number counter is used to draw numbers from 0 to 9 with a predetermined probability. As a result of the lottery, there is no particular change in the gaming state in the case of losing. On the other hand, if the result of the lottery is a win (for example, a win number of 7 is drawn), the main control board 150 opens the electric tulip 134 provided in the special symbol start winning opening 126, Energize the solenoid 174. Thereby, it can be set as the high probability state in which the pachinko ball is easy to enter the special symbol start winning opening.
[0055]
When a pachinko ball wins the special symbol start winning opening 126, the main control board 150 starts a big win lottery with a predetermined establishment using a random number counter. When winning / losing is determined as a result of this big hit lottery, a symbol variation pattern (symbol variation pattern) prepared in advance is selected (may be selected with a random number counter), and an effect including the symbol display control board 160 is included. A command signal is sent to the control board related to the.
[0056]
The symbol display control board 160 displays a symbol variation pattern on the display unit 124 via the display driver 166 based on the received command signal. In this symbol variation pattern, there are various effects such as hitting via reach, missed reach, and missed via reach, and the player can wait for the lottery result with a sense of expectation.
[0057]
Here, in the case of winning, the opening / closing member 129 of the special winning opening 128 is opened for a predetermined time and a predetermined number of times, so that the probability of winning a pachinko ball becomes extremely large, and the player is in an advantageous state. Can do.
[0058]
If a pachinko ball wins the special symbol start winning opening 126 during the symbol variation display, the lottery is performed at that time, but the symbol variation display is waited until the currently displayed symbol variation display is finished. This is notified to the player when the hold lamp 200 is turned on.
[0059]
As described above, in the pachinko game, it is a major premise to make the gaming state in which it is advantageous for the pachinko ball 14 to win the special start winning opening 126, and the player aims at the special start winning opening 126. The pachinko ball 14 is fired.
[0060]
However, there are a plurality of nails, a windmill 118, and the like on the surface of the gauge portion 114, and the pachinko ball 14 drops while moving in an unexpected direction. Nail adjustment can be an important factor for ease of entry. The pachinko ball 14 that has been placed on the stage 20 along with the nail adjustment is expected to win a special start winning opening 126 to some extent depending on the shape of the stage 20. In this case, in the conventional structure, since the shape of the stage 20 is unambiguous, if there is a difference between the design input probability to the special start winning opening 126 and the running input probability when actually operating, Nail adjustment alone could lead to unsatisfactory results.
[0061]
Therefore, in the present embodiment, the notch 22 is provided at the lowest level of the stage 20, that is, in the center in the width direction of FIG. 4, and the peripheral surface of the rotary die 26 is exposed. The rotary die 26 is formed with a first recess 28 and a second recess 30. Therefore, by rotating the rotary die 26, when the first recess 28 is exposed from the notch 22 (the state shown in FIGS. 7 to 9), the winning probability RA of the special start winning opening 126, the second When the recessed portion 30 is exposed from the notched portion 22 (the state shown in FIGS. 10 to 12), the winning probability RB of the special start winning opening 126, and the peripheral surfaces other than the first and second recessed portions 28, 30 are notched portions. It is possible to set three types of winning probabilities, that is, the winning probability RC of the special start winning opening 126 when exposed from the position 22 (the state of FIGS. 4 to 6).
[0062]
The probabilities RA, RB, and RC find differences because the falling directions (angles) of the pachinko balls 14 are different. That is, since the first recessed portion 28 has a narrow circumferential width dimension, when the pachinko ball 14 falls, it falls within a narrow angle θ1 and is most likely to enter the special start winning opening 126. Next, since the second recessed portion 30 has a large width in the circumferential direction, when the pachinko ball falls, the second recessed portion 30 falls at a wide angle θ2, so that the ease of entering the special start winning opening 126 decreases. Finally, on the peripheral surface of the rotary die 26, when the pachinko ball 14 falls, it falls at a considerably wide angle angle (θ3), so it is most difficult to enter the special vibration winning opening 126.
[0063]
Therefore, by setting the rotation state of the rotary die 26 at the pachinko parlor side, there is a difference between the input probability to the special start winning opening 126 in the design and the running input probability when actually operating. It becomes possible to correct.
[0064]
According to the present embodiment, the notch 22 is provided at the lowest part of the stage 20, and the rotary die 26 whose peripheral surface is sequentially exposed to the notch 22 is accommodated in the circular groove 24 communicating with the notch 22. The special start winning opening 126 of the pachinko ball 14 mounted on the stage 20 with a simple structure such as forming the first and second recessed portions 28 and 30 having different circumferential dimensions on the peripheral surface of the rotary die 26. It is possible to change the setting of the winning probability of and set the rotation state of the rotary die 26 at the pachinko parlor side, so that the desired winning probability can be obtained.
[0065]
In the present embodiment, a notch 22 is provided at the lowest position of the stage 20, a rotary die 26 is disposed at the lower part thereof, and first and second recessed portions 28, 30 are provided in the rotary die 26. Although the direction of the pachinko ball 14 falling by rotation is changed, three or more recessed portions may be provided. Alternatively, a member that can be slid laterally may be disposed at the lower portion of the stage 20, and a plurality of recesses may be provided on the upper surface of the slide member so as to be sequentially exposed from the notch 22.
[0066]
Furthermore, in the rotating die 26 of the present embodiment, it is assumed that the rotating speed is set at a constant speed at the pachinko parlor, but an advantageous and disadvantageous state is intentionally set for the player every day, Even during a game, the rotation state may be changed periodically. At this time, step driving may be performed so that the above three forms are changed at regular intervals, not at constant speed rotation.
[0067]
In addition, since the first and second recessed portions 28 and 30 having different circumferential dimensions are provided on the peripheral surface of the rotary die 26, it is possible to set the winning probability to the special start winning opening 126. By replacing with the electric tulip 134, the number of parts can be reduced and the installation space can be prevented from being increased.
[0068]
Further, the movement of the rotary die 26 and the slide member may be visible to the player or may be hidden by the game board surface.
[0069]
In the present embodiment, the rotation state of the rotary die 26 is set on the pachinko parlor side. However, the rotary die 26 is rotated to a state advantageous to the player when winning a preset winning opening. You may give the game nature of changing.
[0070]
【The invention's effect】
As described above, the present invention makes it possible to change the expansive area that drops from the stage to the vicinity of the special start winning opening after the installation in the game hall or during the operation after the setting, and the winning probability to the special starting winning opening is increased. It has an excellent effect that it can be adjusted to the design probability.
