[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a gaming machine provided with an accessory capable of obtaining a right to be in a gaming state advantageous to a player with a predetermined probability when a game ball entered enters a predetermined winning opening. It is about.
[0002]
[Prior art]
Conventionally, in a gaming machine, particularly a pachinko machine, an accessory is provided in the center of the game board, and a pachinko ball that has entered the accessory is rolled on a predetermined stage, and is set in a predetermined winning opening (V winning opening). There is a game specification in which by inputting, a right to be in a game state advantageous to the player is obtained.
[0003]
In this type of pachinko machine, the inside of the accessory is rotated about the Y axis (an axis substantially parallel to the game board surface) to change the internal structure like a stage, and consequently, to win the V winning opening. It has been proposed to change the probability (see Patent Document 1).
[0004]
As described above, since the winning probability to the V winning opening changes and the character or the like can be changed, it is possible to provide a variety of games.
[0005]
Patent Literature 2 further includes a winning disturbance space surrounded by four side plate portions, and the inner wall surfaces of the side plate portions each have a guide surface which is gently inclined so that a game ball can be rolled forward. There has been proposed a structure in which a disturbance space can be rotated around an axis substantially orthogonal to a game board. This pachinko machine is a so-called two-type pachinko machine, and a pachinko ball can flow into the prize disturbance space at a predetermined timing (a prize in a starting prize opening provided at another position on the game board) (movable). Opening of the member for a predetermined time). When a special prize is won, a special game is played, and the probability of winning in the prize disturbance space is increased. In a normal game, the prize disturbance space is at a rotational position where it is difficult to win a special winning opening. In the special game state, the prize disturbance space is rotated 90 ° from the neutral position, and the pachinko ball is set for a predetermined period. To prevent the round from being reset (winning the special winning opening).

[Problems to be solved by the invention]
However, in Patent Literature 1, the flow direction of the basic pachinko ball (rolling from the back side to the front side of the game board) is the same in any stage that is rotated and exposed on the game board surface, and , It is only recognized that the appearance (decoration) of the stage changes, and the difference in the winning probability to the V winning opening cannot be sufficiently appealed.
[0008]
In addition, if the opportunity to shift to each stage is performed at a place other than the center role where the stage was set, the flow of a series of pachinko balls will be overlooked, the player will be distracted, and the player will be unable to win the V winning opening. Timing may be missed.
[0009]
Further, in Patent Document 2, although a plurality of stages are always visible, each stage does not have a special function (for example, the directions of the gentle slopes are all the same), and the rotation angle of the pachinko sphere depends on the rotation angle. The flow is made to fluctuate. In addition, the flow of the pachinko ball is changed by the projections and depressions of the separately provided projections, and the shape does not have a variety of changes for each stage, and it is difficult for a player to recognize the advantages and disadvantages.
[0010]
In consideration of the above facts, the present invention has a plurality of stages in which a difference in the flow of a game ball can be seen at a glance from a player, and each of the stages can be always visible, and the movement of a single game ball can be achieved. It is an object of the present invention to obtain a gaming machine that can be used for a series of operations such as a change of a stage and a winning of a V-prize.
[0011]

A locking device (cylinder) 22 is provided on the right side of the inner frame 14 in FIG.
[0020]
An integrated plate 26 having a ball plate portion 24 is disposed below the glass frame 20. The ball dish portion 24 of the integrated dish is provided with a communication port 23 which communicates with a ball storage tank (not shown) and allows the pachinko balls in the ball storage tank to flow out to the ball dish portion 24.
[0021]
One side (left side in FIG. 1) of the integral plate 26 is attached to the inner frame 14 so as to be openable and closable. An ashtray 28 is arranged on the lower left side on the front surface of the integrated tray 26, and a firing handle 30 for adjusting the flight distance of a hit ball fired from a firing device (not shown) is provided on the lower right side.
[0022]
In the window of the inner frame 14, a game board 32 which can be exchanged by being mounted on a game board mounting table is installed corresponding to the window.
[0023]
As shown in FIG. 2, the game board 32 has a substantially circular game area surrounded by an outer band 36 and an inner band 38. The game board 32 has three specifications.
[0024]
The game board 32 has a windmill 39, nails (not shown), a center role 42, a start winning prize port 43 provided above the center role 42, and three kinds of prizes located on the right side of the center role 42 in FIG. The game parts such as the opening 45, the big winning opening 44 thereunder, the winning device (upper) 48 and the winning device (lower) 49 located on the left side of the center role 42 in FIG. The out port 54 is disposed at the bottom.
[0025]
3 to 8 show the detailed structure of the center role object 42. FIG.
[0026]
A decoration plate 100 is provided at the forefront of the center role object 42, and a rectangular frame which abuts against the periphery of the hole when the center role material 42 is attached to a hole (not shown) provided in the game board 32. A flange portion 102 is formed.
[0027]
The inside of the flange portion 102 is a rectangular window portion 104, and a rotating body 106, which is a main component of the center role 42, is exposed.
[0028]
The rotating body 106 includes a rectangular cylindrical body 108 and a gear 110 attached to an intermediate portion in the depth direction of the rectangular cylindrical body 108 along the outer periphery.
[0029]
The rectangular cylindrical body 108 is supported by a guide (not shown) so as to be rotatable about the axis of the gear 110.
[0030]
The gear portion 110 has a circular outer peripheral end, and has a tooth portion 110A. The tooth portion 110A is connected to a drive shaft of a motor 114 via a transmission 112. Thus, the rectangular cylindrical portion 108 can rotate around the axis of the gear portion 110 at a predetermined rotation speed by the driving force of the motor 114.
[0031]
The rectangular cylindrical portion 108 includes a bottom plate portion 108A, a top plate portion 108B, and a pair of wall plate portions 108C and 108D, and the motor 114 rotates at a 90 ° pitch so that each of the motors 114 is substantially horizontal. It is controlled to make it.
[0032]
The bottom plate portion 108A functions as a stage in the normal game mode. When the bottom plate portion 108A is in a substantially horizontal state, the game mode is the normal game mode.
[0033]
In the normal game mode, the bottom plate portion 108A is an inclined surface that gradually becomes lower from the front of the game board to the back. For this reason, the pachinko ball flowing into the bottom plate portion 108A basically rolls to the far side of the game board 32.
[0034]
The pair of wall plates 108C and 108D function as a probability variation stage. When any of the wall plates 108C and 108D is in a substantially horizontal state, the mode is the probability variation mode. In the present embodiment, the right wall plate portion 108C as viewed in FIG. 9 is a stage in the low-probability game mode, and the left wall plate portion 108D is a stage in the high-probability game mode.
[0035]
Therefore, when one wall plate portion 108C is in a substantially horizontal state by the driving force of the motor 114, a low-probability game mode is set, and when the other wall plate portion 108D is in a substantially horizontal state, a high-probability game mode is set. The game mode is set. The discrimination between the low-probability game mode and the high-probability game mode is based on the position and shape of the protrusion 116 formed on each of the wall plates 108C and 108D. Note that a projection 116 is also formed on the bottom plate 108A.
[0036]
In the probability variation game mode, the wall plate portions 108C and 108D have inclined surfaces that become lower from the back side to the front side of the game board. Therefore, the pachinko balls flowing into the wall plate portions 108C and 108D basically roll toward the front side of the game board 32.
[0037]
On the lower side of the rectangular window 104 of the decorative plate 100, a pocket portion 118 protruding toward the trouble side of the game board 32 is formed. The pocket portion 118 is divided into three in the width direction, and is adapted to receive pachinko balls rolling from the bottom plate portion 108A and the pair of wall plate portions 108C and 108D. The central receiving port among the three divided receiving ports is a V winning port 118A, and when a pachinko ball wins in the V winning port 118A, the right of jackpot processing is acquired. The pockets 118 other than the V winning opening 118A are detached (disengaged pockets 118B), and the right to the jackpot processing cannot be obtained.
[0038]
The probability fluctuations of the wall plate portions 108C and 108D indicate the probability of winning in the V winning opening 118A. Therefore, for the player, the high probability game mode in which the wall plate portion 108D is the stage is most advantageous. State.
[0039]
A guide unit 120 for guiding the pachinko ball to the inside of the rectangular cylindrical portion 108 is disposed on the back side of the game board 32 of the rotating body 106.
[0040]
The guide unit 120 includes a first guide member 122 for sending the pachinko ball that has won the starting winning opening 43 provided above the center role object 42 into the rectangular cylindrical portion 108, and a back side from the stage. A second guide member 124 that receives the rolling pachinko ball and discharges the ball at a predetermined time is configured in combination.
[0041]
The first guide member 122 has a box shape in which a wall plate 122B is formed integrally with a main plate 122A at a peripheral edge thereof, and an opening thereof is directed toward the rotating body 106. The first guide member 122 is attached to the rotating body 106 so as to rotate integrally with the rotating body 106. A plate 126 is attached to the opening surface of the first guide member 122, and the inside of the first guide member 122 is isolated except for a part.
[0042]
An opening 128 is formed in a wall plate 122B (referred to as an upper wall plate 122BU) serving as an upper end when the rotator 106 is in the normal game mode to receive a pachinko ball that has won the starting winning opening 43. The upper wall plate 122BU corresponds to the top plate 108B of the rectangular cylindrical body 108.
[0043]
A substantially triangular protrusion 138 is formed at the center of the wall plate 122 (referred to as a lower wall plate 122BL) at a position facing the upper wall plate 122BU in which the opening 128 is formed. The lower wall plate 122BL corresponds to the bottom plate 108A of the rectangular cylindrical body 108.
[0044]
The pachinko ball that has flowed in from the opening 128 falls toward the protrusion 138 and is distributed to the left and right according to the fall trajectory.
[0045]
Here, the lower wall plate 122BL is formed with a step that is higher than the bottom plate portion 108A of the rectangular cylindrical body portion 108, and as a result, the pachinko ball falls on the bottom plate portion 108A. However, since the bottom plate portion 108A has an inclined surface which becomes lower from the front side to the back side of the game board 32, most of the pachinko balls roll to the back side of the bottom plate portion 108A.
[0046]
A chance zone 132 (see FIGS. 7 and 9) formed on a second guide member 124 described later is arranged at an intermediate position in the width direction of the space having the step, and the chance zone 132 is won. Whether or not the lottery in the rotation direction of the rotating body 106 is possible is determined depending on whether or not the lottery is performed. Note that the space on both sides of the chance zone 132 is a departure zone 134, and no right for lottery is given.
[0047]
A pair of wall plates 122B (referred to as side wall plates 122BS) adjacent to the upper wall plate 122BU in which the opening 128 is formed is formed with a recessed portion 136 having a central portion recessed from the outside to the inside. In addition, the concave portion 136 can also be the protrusion 140 when viewed from inside the first guide member 122. The protruding end of the protruding portion 140 has a substantially triangular shape.
[0048]
When the horizontal wall plate 122BS is in the state of the probability varying game mode, the horizontal wall plate 122BS is rotated by approximately 90 ° to the right or left from the state of the normal game mode, and becomes a substantially horizontal state.
[0049]
In this state, it can be a falling surface of a pachinko ball passing through the through hole 141 of the main plate 122A provided on both sides of the opening 128 of the upper wall plate 122BU.
[0050]
The through hole 141 communicates with a guide path 142 formed in a second guide member 124 described later. The guide path 142 has a function of guiding the ball that has won the start winning opening 43 to the through hole 141.
[0051]
The second guide member 124 is attached so as to face the back side of the first guide member 122 (the outer surface of the main plate 122A). Here, the upper wall plate 122BU in which the opening portion 128 and the through holes 141 on both sides of the opening portion 128 in the first guide member 122 are projected to the rear side of the main plate 122A. Openings (receiving ports) of the through holes 141 are provided at both ends of the protruding portions.
[0052]
A pair of arm portions 144 of the second guide member 124 are provided so as to sandwich the pair of through holes 141. The pair of receiving ports are provided with an outlet 146 of the arm 144, and at this position, the first guide 122 and the arm 144 of the second guide 124 are in communication with each other.
[0053]
The arm 144 has a substantially L-shape, and an opening 148 is formed at a position facing upward in the probability variation game mode. The openings 148 are positioned at positions where the openings 128 of the first guide member 122 are positioned in the normal game mode depending on the rotational position of the rotating body 106. The opening 148 is adapted to receive a pachinko ball that has won the starting winning opening 43.
[0054]
The pachinko ball that has won the start winning opening 43 is closed by the shielding plate 150 before the opening 128 (or 148) while the rotating body 106 is rotating, that is, until the opening 128 (or 148) is positioned. Is to be retained by The shielding plate 150 is opened and closed by driving the solenoid 152.
[0055]
When the pachinko ball is received, the pachinko ball passes through the guide path 142 inside the arm portion 144, and the pachinko ball is guided to the delivery port 146, and is sent out to the through hole 141 of the first guide member 122. ing.
[0056]
The second guide member 124 includes, in addition to the arm portion 144, a main body portion 154 that forms an inverted triangle in a normal game mode.
[0057]
The main body 154 has an opening at each vertex toward the rectangular cylindrical body 108.
[0058]
Here, in the opening corresponding to the bottom plate portion 108A of the rectangular cylindrical body portion 108, since the bottom plate portion 108A is inclined so as to be lower toward this opening direction, the chance zone 132 where the pachinko ball flows in. Function as The chance zone 132 is provided with a ball detection sensor 156. When a win of a pachinko ball is detected with a predetermined probability, the rotation direction of the rotating body 106 is randomly selected. That is, since the chance zone 132 is located at the center of the step between the first guide member 122 and the bottom plate portion 108A as described above, only a part of the pachinko ball rolling on the bottom plate 108A is in the chance zone 132. There is a possibility of winning. The chance zone 132 is slightly inclined so as to be lower from the bottom plate portion 108A side to the back side, and the winning pachinko ball is not discharged.
[0059]
When the rotation direction of the rotating body 106 is determined as a result of the lottery, the rotating body 106 is rotated by approximately 90 ° in any direction from the state of the normal game mode to the low-probability game mode or the high-probability game mode. Rotate.
[0060]
At this time, the pachinko ball that has won the chance zone 132 passes through the main body 154 of the second guide member 124 and moves to the discharge zone 158 at another vertex position (see FIGS. 7 and 9). Has become. The pair of discharge zones 158 are assembled so as to be accommodated in the recess 136 of the first guide member 122. The discharge zone 158 is slightly inclined so as to be lower from the back side to the wall plates 108C and 108D of the rectangular cylindrical body 108. For this reason, the pachinko balls that have migrated from the chance zone 132 are discharged from the discharge zone 158 to the wall plates 108C and 108D.
[0061]
An example of a basic flow of a three-class game using the center role object 42 having the above configuration is as follows.
[0062]
(1) A pachinko ball wins in the starting winning opening 43 during the normal game mode
(2) Entering the first guide member 122 from the opening 128 of the first guide member 122
{Circle around (3)} Dropping onto the bottom plate 108A of the rectangular cylindrical body 108
{Circle around (4)} Rolling backward along the inclination of the bottom plate 108A (possibility of winning the chance zone 132)
5) Lottery on condition of winning the chance zone 132 (for example, high probability mode)
(6) Rotation of the rotator 106 (as an example, approximately 90 ° counterclockwise rotation when viewed from the front of the game board 32)
{Circle around (7)} The release of the pachinko balls that have moved from the chance zone 132 to the discharge zone 158 and the release of the pachinko balls that have won the starting winning opening 43 (as an example, rolling on the wall plate portion 108D).
{Circle around (8)} A prize in the pocket portion 118 (as an example, a right is generated in a prize in the V zone 118A).
The operation of the present embodiment will be described below.
[0063]
When the game is started in the state of the normal game mode, the bottom plate portion 108A is the stage (see FIG. 9A).
[0064]
When the player grips the handle 30 and performs an operation for firing, a pachinko ball is launched with an intensity corresponding to the handle operation amount (rotation amount).
[0065]
When the pachinko ball is hit, the ball is guided by the outer band 36 and the inner band 37 and falls while moving unpredictably while abutting on a nail, a windmill, or the like provided on the game board 32. Here, when the pachinko ball wins in the starting winning opening 43, it flows in from the opening 128 of the first guide portion 122, falls into the substantially triangular protrusion 138 of the lower wall plate 122BL, and has an irregular trajectory. It falls to the part 108A.
[0066]
At this time, usually, it rolls to the back side along the inclined surface of the bottom plate portion 108A and enters the chance zone 132 or the disengagement zone 134. It should be noted that the pachinko ball may rarely enter the pocket portion 118 against the inclination due to the falling momentum. At this time, if the player wins the V winning opening 118A, it will be a big hit.
[0067]
Here, when the player rolls to the rear side of the bottom plate portion 108A in a normal flow and wins the chance zone 132, a lottery is executed. When the rotation direction is determined as a result of the lottery, the motor 114 is driven to rotate the rotating body 106.
[0068]
(Low probability game mode)
As shown in FIG. 9B, when the result of the lottery is the low-probability game mode, the rotating body 106 rotates approximately 90 ° clockwise as viewed from the front of the game board 32. In this state, one wall plate 108C has a role as a stage. The one wall plate portion 108C is an inclined surface which becomes lower from the back side to the near side, and has a projection 116 which is relatively hard to win in the V zone.
[0069]
Further, the first guide member 122 and the second guide member 124 rotate simultaneously with the rotation of the rotating body 106, and the opening 148 of the one arm portion 144 corresponds to the starting winning opening 43. On the other hand, the pachinko ball that has won the chance zone 132 passes through the main body 154 and moves to the discharge zone 158 corresponding to the one wall plate 108C.
[0070]
As a result, the pachinko ball is discharged from the discharge zone 158 to one wall plate portion 108C and rolls along the slope, but the rolling direction is changed by the projection 116, and the V zone 118A is won. Hateful.
[0071]
Also during this time, the pachinko ball that has won the start winning opening 43 flows in from the opening 148 of the one arm portion 144, is delivered from the outlet 146 to the through-hole 141, and passes through the first guide member 122. , And flows into one wall plate portion 108C, so that the greater the number of winning in the starting winning opening 43, the higher the probability of winning in the V zone 118A.
[0072]
(High probability game mode)
As shown in FIG. 9C, when the result of the lottery is the high-probability game mode, the rotating body 106 rotates approximately 90 ° counterclockwise as viewed from the front of the gaming board 32. In this state, the other wall plate portion 108D has a role as a stage. The other wall plate portion 108D is an inclined surface that becomes lower from the back side to the front side, and has a projection 116 that is relatively easy to win the V zone.
[0073]
In addition, the first guide member 122 and the second guide member 124 rotate simultaneously with the rotation of the rotating body 106, and the opening 148 of the other arm portion 144 corresponds to the starting winning opening 43. On the other hand, the pachinko ball that has won the chance zone 132 passes through the main body 154 and moves to the discharge zone 158 corresponding to the other wall plate 108D.
[0074]
As a result, the pachinko ball is discharged from the discharge zone 158 to the other wall plate portion 108D and rolls along the slope. However, since the protrusion 116 does not change its rolling direction so much, the pachinko ball is moved to the V zone 118A. Is easy to win.
[0075]
Also during this time, the pachinko ball that has won the start winning opening 43 flows in from the opening 148 of the other arm 144, is delivered from the outlet 146 to the through-hole 141, and passes through the first guide member 122. , And flows into the other wall plate portion 108D, so that the greater the number of winning in the starting winning opening 43, the higher the probability of winning in the V zone 118A.
[0076]
That is, since the probability of winning in the V zone 118A changes depending on the lottery, a variety of games can be played.
[0077]
Also, since the changing stage is always exposed, even for beginners who are not familiar with this pachinko machine, the game specifications are easy to understand, for example, comparing the stage between the high probability game mode and the low probability game mode Can be. For this reason, it is possible to have a sense of expectation in the direction of rotation depending on the result of the lottery, and to always maintain the taste.
[0078]
Furthermore, by providing the chance zone 132 in the center role 42 that triggers the rotation of the rotating body 106, the flow of the pachinko ball in the center role 42 after the pachinko ball has won the start winning opening 43. In contrast, the attention of the player can be attracted separately from the V zone 118A. In addition, without changing the specifications of the entire game board 32, the rotation of the rotating body 106 can be performed in various forms by changing the specifications of only the center accessory 42 (for example, increasing or decreasing or moving the chance zone 132). Become.

(Rotation position of rotating body after big hit processing)
When the player wins the V zone 118A and finishes opening the special winning opening 44 a predetermined number of times (big hit processing), the rotator 106 basically returns to the normal game mode, but in the present embodiment, a separate lottery is executed. By maintaining the current state (low-probability game mode, high-probability game mode), it is possible to obtain the same effect as the probability variation state and the time-saving mode, which is called for a kind of pachinko machine.
[0080]
That is, at the time of winning in the chance zone 132, a probability change lottery is executed separately from the lottery in the rotation direction.
[0081]
After that, when the winning in the V zone 118A is made, the result of the probability change lottery becomes effective. After the big hit, the number of pachinko balls flowing into the center role object 42 is determined, and the current state (until the set number flows) is determined. (Low-probability game mode, high-probability game mode). As a result, the pachinko balls that have won the start winning opening 43 all roll toward the pocket portion 118 along the stage inclined toward the front, so that it is possible to expect to win the V zone 118A again in a relatively short time.
[0082]
Note that the probability change lottery is not limited to winning in the chance zone 132, and may be performed at another different time. In addition, the probable change state may be performed not only until the next prize in the V zone 118A, but also in time, or may be terminated upon receiving a prize in another prize tool.
[0083]
Further, the maintenance of the state is not limited to the number of inflows into the center role object 42 after the end of the jackpot, but may be until the next prize in the V zone 118A or for a predetermined time.
[0084]
Further, in the present embodiment, the bottom plate 108A and the wall plates 108B and 108D of the rectangular cylindrical body 108 are applied as the stage, and the game mode is changed by the rotation of the rotating body 106. The inclination angle may be changed singly, or the number and position of the protrusions 116 may be changed.

【The invention's effect】
As described above, according to the present invention, it is possible to have a plurality of stages, each of which can be always visible, and to trigger a series of operations such as changing a stage, obtaining a V prize, etc. by the movement of a single game ball. Has an excellent effect of being able to obtain
