In the technique of Patent Document 1, a specific winning opening having a certain opening width only moves in the left-right direction. For this reason, there is little change, and the interest that a player feels is small.
JP 2003-225386 A

  In view of such circumstances, it is an object of the present invention to provide a variable prize apparatus that allows a player to feel a new interest by adding a new movement to the variable prize apparatus.

Means and effects for solving the problems

The first invention for solving the above-described problems is
A variable prize of a pachinko gaming machine in which a pachinko ball is driven into a game area formed on the board surface of the game board and a game in which a pachinko ball flowing down the game area is awarded to a prize area formed on the game board is performed. A device,
A pair of upright plate portions that are arranged so as to stand up in the direction intersecting with the board surface, and can be moved independently from each other in the left-right direction as the receiving width of the pachinko balls, and the pair of upright plate portions By having a bottom plate portion that is disposed between and extending and contracting with the movement of the upright plate portion, a receiving region for receiving a pachinko ball flowing down the game region is formed and received in the receiving region Guide means capable of guiding a pachinko ball to the winning area;
First driving means for linearly reciprocating one of the pair of upright plate portions along the board surface on the player side of the game board;
Second driving means for linearly reciprocating the other of the pair of upright plate portions along the board surface on the player side of the game board;
A first state in which the pair of upright plate portions moves in the same direction across the winning area while maintaining the receiving width equal to or larger than the outer diameter of the pachinko ball, and the pair of upright plate portions has the receiving width. Control means for controlling the operation of the guide means by driving the first and second drive means in order to switch between the second state, which is larger than the first state and stops. Yes.

  The present invention is configured as described above, and the pair of upright plate portions of the guide means move so as to approach each other by the first and second driving means and are arranged in the first state (first by the control means). (1 control) and move away from each other so that the receiving width of the guide means is larger than the first state (second control by the control means).

  When the guide means is arranged in the first state, the player is relieved as the guide means moves in the left-right direction. When the guide means is arranged in the second state, the player can play the game with a high sense of security or with a sense of security that the game will be won with certainty. In addition to moving the guide means, it is possible to realize a winning mode in which the receiving width of the guide means is different between when the first control is performed and when the second control is performed. In addition, it is possible to play an entertaining game.

In addition, the winning area is configured to include a first winning opening and a second winning opening located below the first winning opening,
The bottom plate portion of the guide means is arranged such that a plurality of bottom plate pieces slidable in the left-right direction of the game board overlap in the vertical direction,
In the first state, the bottom plate portion has a stacked form in which the plurality of bottom plate pieces are stacked and arranged between the pair of upright plate portions, and the pair of upright plate portions are the first and first While crossing the second prize opening, the bottom plate portion covers the second prize opening and guides the pachinko balls in the receiving area to the first prize opening,
In the second state, the bottom plate portion has a stepped shape in which the plurality of bottom plate pieces are offset and arranged in a stepped manner so as to expand upward between the pair of upright plate portions. The pachinko balls are guided to the second winning opening.

  The ball received by the guide means arranged in the first state is arranged between the pair of upright plate portions, and is guided to the first winning opening by the bottom plate portion provided so as to be stretchable by sliding. The balls received by the guide means arranged in two states are also guided to the second winning opening by the bottom plate portion. Then, by changing the winning process of the first winning opening and the winning process of the second winning opening, the privilege to the player is changed, or a privilege other than the winning rate given to the player is given. Can give players more interest.

And while the pair of upright plate portions move on a single guide rail arranged in the horizontal direction along the board surface,
The first and second drive means are each constituted by a rotary actuator, and the rotary drive of each rotary actuator is performed by linear movement of the corresponding upright plate portion via a rotary arm whose arm length can be expanded and contracted. It can be converted and transmitted.

Specifically, the drive means is a control motor,
The pair of upright plate portions of the guide means are connected so that one end portion of the rotation arm is rotatable around a direction intersecting the moving direction of the guide means,
A cylindrical body is attached to the motor shaft of the control motor in a direction perpendicular to the axis of the motor shaft, and the other end of the rotating arm is fitted and inserted so as to freely enter and exit the cylindrical body,
The guide means may be moved along the board surface of the game board by turning the motor shaft of the control motor by a predetermined angle and moving the turning arm in and out of the cylindrical body. it can.

  By sharing the guide rail and configuring the first and second driving means with the rotary actuator and the rotating arm, the arrangement space can be reduced and the configuration can be made compact. be able to. In particular, when the driving means is a control motor, the control becomes easy.

And the said control means of the said guide means to the 3rd state to which the said receiving width expands rather than the said 1st state, and the guidance of the pachinko ball to the said 2nd prize winning opening is restrict | limited by the said baseplate part. In order to switch the operation, while driving at least one of the first and second drive means to control the operation of the guide means,
When the operation of the guide means is switched to the third state, the pachinko balls received in the receiving area in the third state are switched to the first or second state within a predetermined time. It is possible to guide to the first or second winning opening.

  Since this control realizes a third state different from the first and second states, the player's interest is further enhanced. When the guide means is arranged in the third state, even if the balls received by the guide means cannot be guided to the first and second winning holes, the first and second winning holes are controlled by the subsequent control. Can guide you. In particular, since the time during which the third state is maintained is limited to a predetermined time, the degree of freedom of the receiving area can be increased without causing inconvenience that the balls received by the guide means overflow in the third state. Enhanced. Then, by realizing the third state described above in the probability changing state, the normal gaming state (for example, the first state of the guide means) or the big hit state (for example, the second state of the guide means) in the probability changing state. The guide means can be operated differently from the above, and the player can feel further interest.

And a transition determining means for determining whether to switch to the first state or the second state after switching the operation of the guide means to the third state based on a predetermined condition,
The first and second winning mouths are different from each other in the privilege given to the player when winning.
The control means can switch the control of the operation of the guide means to the first or second state after entering the third state based on the determination of the transition determining means.

  The guide means in the third state is switched to the first state or the second state by the transition determining means. Moreover, the first and second winning mouths have different points when winning. As a result, the player is asked whether the guide means shifts to the first state after entering the third state, or shifts to the second state (in other words, whether to win the first prize opening, or A new interest is given to think about whether or not to win the second prize opening. Moreover, a privilege (for example, relief of a player who falls into a so-called “hamari” state) can be given to a player who satisfies a predetermined condition.

  And the 2nd invention for solving the above-mentioned subject is a pachinko gaming machine characterized by mounting the above-mentioned variable prize-winning device on the board of the above-mentioned game board.

The gaming area of the pachinko gaming machine includes a big winning opening that increases the winning rate of pachinko balls flowing down the gaming area when a big hit state occurs when a predetermined jackpot occurrence condition is satisfied,
The variable prize-winning device is arranged below the big prize opening,
The guide means of the variable winning device is switched from the first state to the second state when the jackpot state is reached, and a pachinko ball that flows down without winning the big winning opening is received in the receiving area and the second winning state is received. Can be guided to the winning entrance.

  Since the second invention is a pachinko gaming machine having the variable winning device of the first invention, the same effects as the first invention are achieved. In particular, when the variable winning device is arranged below the grand prize opening, by switching the guide means from the first state to the second state, the ball that has not won the big prize opening is received by the guide means, The second prize opening can be awarded. As a result, the balls that have not won the big winning opening in the big hit state are not collected at the out opening (in other words, the balls are not reduced), and the gaming state is advantageous to the player.

  A pachinko gaming machine 100 according to an embodiment of the present invention will be described. 1 is a front view of a pachinko gaming machine 100, FIG. 2 is a plan view of a variable winning device 201 of the first embodiment, FIG. 3 is a side sectional view of the variable winning device 201, and FIG. FIG. 5A is a front view of a state in which the guide member 15 is disposed at a substantially central portion in the left-right direction. Similarly, FIGS. 5B and 5C are front views of the state in which the guide member 15 is disposed at the left and right ends. FIG. 6B is a front view of the guide member 15 in the second state, FIG. 6A is a plan view of the guide member 15 in the third state, and FIG.

  First, the pachinko gaming machine 100 will be described. As shown in FIG. 1, a symbol display unit 3 made up of a liquid crystal display is arranged at a substantially central portion of the game area 2 formed on the game board 1 of the pachinko gaming machine 100. Below the symbol display section 3, a start winning opening 4 and a big winning opening 5 are arranged. The big winning opening 5 is composed of an attacker type electric winning device. A through chucker 6 is disposed on the left side of the symbol display unit 3, and left and right winning ports 7 and 8 are disposed on both sides of the start winning port 4. An out port 9 is provided at the lowermost center of the game board 1 for collecting the balls that have not won any winning ports.

  At the lower part of the game board 1, a launching device 11, an upper plate 12 and a lower plate 13 are provided. Pachinko balls (not shown, hereinafter also referred to as “balls”) in the upper plate 12 are driven into the game area 2 of the game board 1 by the launcher 11. When the balls that have been placed win the start winning opening 4 or the left and right winning openings 7, 8, a predetermined number of balls are paid out to the upper plate 12. When the upper plate 12 is filled with the dispensed balls, the balls are automatically dispensed to the lower plate 13.

  In the gaming board 1 of the pachinko gaming machine 100 according to the present embodiment, a game in which the width in the left-right direction is narrower than the gaming area 2 of the portion where the symbol display portion 3 is disposed in the portion below the winning prize opening 5. A region (lower game region 2a) is formed. And in the part of the lower game area 2a, the variable winning device 201 of the first embodiment is arranged immediately upstream of the out port 9. The variable winning device 201 of the first embodiment will be described. The variable winning device 201 is disposed on the back side of the game board 1 and a guide member 15 (guide means) disposed between the game board 1 and the glass plate 14 of the pachinko gaming machine 100, and the guide member 15 is attached to the pachinko game. First and second drive means (in the case of the present embodiment, first and second control motors 16 and 17) that reciprocate along the left-right direction of the machine 100, the first state and the second state of the guide member 15 Control means (not shown, for example, a CPU provided in the control unit of the pachinko gaming machine 100) for switching between states (described later).

  The guide member 15 will be described. As shown in FIGS. 2 and 3, the guide member 15 includes a pair of upright plate portions 18 and a plurality of layers (in the case of the present embodiment, six plates) arranged in multiple stages between the pair of upright plate portions 18. ) And a bottom plate portion 21 made up of the bottom plate piece 19. At the lower end portion of the upright plate portion 18, a protruding portion 18 a protrudes toward the back side (the game board 1 side). The protrusion 18a protrudes to the back side (back side) of the game board 1 via a guide groove 22 provided in the left-right direction on the game board 1, and is pin-connected to the arm 23 so as to be rotatable in a horizontal plane. ing. In the case of the variable winning device 201 of the first embodiment, the guide groove 22 is single, and the protrusions 18 a of the pair of upright plate portions 18 are inserted through the same guide groove 22. On the back side of the game board 1, first and second control motors 16 and 17 are disposed corresponding to the pair of upright plate portions 18. Each of the control motors 16 and 17 is arranged with the axis of the motor shafts 16a and 17a along the height direction. Since the first and second control motors 16 and 17 have the same configuration, only the first control motor 16 will be described in this specification. A cylinder body 24 is attached to the motor shaft 16 a of the control motor 16 in a direction perpendicular to the axis thereof, and an arm 23 is inserted into the cylinder body 24. When the motor shaft 16a of the control motor 16 is rotated in a predetermined direction, the guide member 15 is guided in the guide groove 22 to reciprocate in the left-right direction. At this time, the arm 23 enters and exits the cylindrical body 24.

  2 and 3, the back surfaces of the pair of upright plate portions 18 (surfaces facing the board surface of the game board) are brought into contact with the board surface (front surface) of the game board 1, and their contact locations. It is also possible to attach guide means (a plurality of pulleys 37 and the like) to the pair of upright plate portions 18 so as to reliably maintain the level. Similarly, a guide means (such as a pulley 38) may be attached to a contact portion between the portion of the pair of upright plate portions 18 and the protrusion 18a and the back surface of the game board 1. In this way, by attaching guide means (not shown) such as pulleys to places where sliding is assumed, such as portions of the guide protrusions 25 (described later) of the bottom plate pieces 19a and 19b, they are operated more smoothly. It becomes possible to make it. Of course, guide means such as pulleys 37 and 38 may not be attached.

  Of the bottom plate pieces 19 of each step in the bottom plate portion 21, the bottom plate pieces 19 of each step excluding the bottom plate piece 19c of the lowest step are divided at a substantially central portion in the left-right direction. Therefore, the right bottom plate piece 19 in the front view of the pachinko gaming machine 100 is described as “bottom plate piece 19a”, and the left bottom plate piece 19 is also described as “bottom plate piece 19b”. Of the bottom plate pieces 19 at each stage, only the outer ends of the uppermost bottom plate pieces 19 a and 19 b are fixed to the upright plate portion 18. In addition, on the bottom surfaces of the bottom plate pieces 19a and 19b of each step except the bottom plate piece 19c at the lowest step, inverted T-shaped guide protrusions 25 are along the moving direction (the left-right direction of the pachinko gaming machine 100). A T-groove 26 is provided on the upper surface of each of the bottom plate pieces 19a to 19c except for the uppermost bottom plate pieces 19a and 19b. . Since the guide protrusion 25 has an inverted T shape, there is no possibility that the bottom plate pieces 19a to 19c of each step will fall. The balls that have been driven into the game area 2 of the pachinko gaming machine 100 are received in the receiving area V formed by the pair of upright plate portions 18 and the bottom plate pieces 19a to 19c of the respective stages. In addition, on the upper surfaces of the bottom plate pieces 19a to 19c, the end surface on the near side (player side) is higher than the end surface on the back side (game board 1 side). That is, the upper surfaces of the bottom plate pieces 19a to 19c are inclined (for example, the inclination angle is 5 degrees) from the front side to the back side. As a result, the pachinko balls received in the receiving area V of the guide member 15 are converted into the upper winning port 27 (first winning port) and the lower winning port 28 (second winning port) formed on the surface of the game board 1. ) Is easy to enter (described later).

  The pair of upright plate portions 18 of the guide member 15 can be independently moved in the left-right direction by rotating the motor shaft 16a of each control motor 16 in a predetermined direction. 19a and 19b are also slid in the left-right direction. That is, the guide member 15 is in a first state in which the pair of upright plate portions 18 are close to each other (the state shown in FIG. 4, the ball receiving width is minimum, the ball can be moved in the left-right direction, A state in which a winning can be made in the upper winning opening 27), a second state in which the pair of upright plate portions 18 are separated from each other (the state shown in FIG. 5 and the ball receiving width is larger than that in the first state, and the horizontal direction) And the pair of upright plate portions 18 are separated from each other than the first state and are closer to each other than the second state. State (in the state shown in FIG. 6 or FIG. 7, the ball receiving width is larger than that in the first state and can be moved in the left-right direction. Restricted (cannot win or the winning rate is low) It is placed in or Re. When the guide member 15 is disposed in the first state, the inner width (acceptance width) of the pair of upright plate portions 18 is slightly wider than the outer diameter of the pachinko ball. When the guide member 15 is arranged in the second state or the third state, the bottom plate pieces 19a, 19b of each step are slid in the left-right direction, and the inner width increases toward the upper side (steps offset in a step shape) Form). And if the maximum value (acceptance width) of the inner width of the pair of upright plate portions 18 in each state is W1 to W3, W1 <W3 <W2. As a result, the size of the receiving region V of the guide member 15 is maximum in the second state and minimum in the first state. As shown in FIGS. 4B and 4C, since the guide member 15 can reciprocate in the left-right direction within the width of the lower game area 2a, the guide member 15 in the first state is It is arranged at a substantially central position (position (a) in FIG. 4) or at an end position in the left-right direction (position (b) or (c) in FIG. 4).

  An upper prize opening 27 is provided at a substantially central portion in the left-right direction in the lower game area 2 a of the game board 1, and a lower prize opening 28 is provided immediately below the upper prize opening 27. When the guide member 15 is in the first state and is disposed at the center in the left-right direction of the pachinko gaming machine 100, the uppermost bottom plate pieces 19a and 19b forming the receiving area V are disposed immediately in front of the upper winning opening 27. Is done. The pachinko ball received in the receiving area V of the guide member 15 rolls the uppermost bottom plate pieces 19a, 19b toward the back side and wins the upper winning opening 27 (see FIG. 4A). When the guide member 15 is disposed at a position other than the center in the left-right direction, the back surface portion of the receiving area V is closed by the game board 1, so that the pachinko ball is held while being received by the guide member 15 (FIG. 4 (b) and (c)).

  When the guide member 15 is arranged in the second state, the lowermost bottom plate piece 19c forming the receiving area V is arranged immediately before the lower winning opening 28. At this time, the pachinko ball received by the guide member 15 rolls the bottom plate piece 19c at the lowermost stage toward the back side and wins the lower winning opening 28 (see FIG. 5B).

  When the guide member 15 is arranged in the third state, the bottom plate pieces 19a, 19b on either side of each stage cover the lower winning opening 28. In addition, the bottom plate pieces 19a and 19b of each step are separated from each other, and form a step shape. For this reason, the pachinko ball received by the guide member 15 does not win the upper winning port 27 or the lower winning port 28 (see FIG. 6B and FIG. 7B).

  Next, with reference to FIG. 4 thru | or FIG. 8, the effect | action of the variable prize-winning apparatus 201 in the pachinko game machine 100 of a present Example is demonstrated.

<Normal gaming state (first state)>
As shown in FIGS. 4A to 4C, in the pachinko gaming machine 100 according to the present embodiment, the guide member 15 of the variable winning device 201 in the normal gaming state (the gaming state that is not the big hit state) While maintaining the 1 state (that is, keeping the inner width W1 of the pair of upright plate portions 18 constant), the lower game area 2a is reciprocated in the left-right direction. This state is realized by reciprocatingly rotating the motor shafts 16a and 17a of the respective control motors 16 and 17 in the same direction (first control). When a pachinko ball driven into the game area 2 of the game board 1 of the pachinko gaming machine 100 wins the start winning opening 4, a predetermined number of balls are paid out and a big hit lottery is performed. The symbol display unit 3 changes, and a jackpot symbol or a missing symbol is displayed based on the lottery result. When the lottery result is a jackpot, the jackpot symbol is displayed on the symbol display unit 3 and the big prize opening 5 is opened. The pachinko ball that has flowed down to the lower game area 2a without receiving a prize at either the start winning opening 4 or the left and right winning openings 7 and 8 and received by the guide member 15 reciprocating in the left-right direction, When placed in the center in the left-right direction, the upper surface of the bottom plate pieces 19a, 19b on the uppermost stage rolls to win the upper prize opening 27. Since the upper surfaces of the bottom plate pieces 19a, 19b, and 19c of each step are inclined so as to become lower toward the back side, the pachinko balls received by the guide member 15 surely win the upper prize opening 27. In the case of the pachinko gaming machine 100 of the present embodiment, winning in the upper winning opening 27 is performed in the same manner as when winning in the starting winning opening 4.

<Big hit state (second state)>
When the pachinko ball driven into the game area 2 wins the start winning opening 4 or the upper winning opening 27 and is a big hit, the pair of upright plate portions 18 of the guide member 15 are, as shown in FIG. It moves in the direction away from each other and is placed close to the inner wall surface of the lower game area 2a (second state). This state is realized by rotating and stopping the motor shafts 16a, 17a of the control motors 16, 17 in the opposite direction (the direction in which the pair of upright plate portions 18 are separated) (second control). ). At this time, since the bottom plate pieces 19a, 19b of each step are slid in the left-right direction to have a step shape offset in a stepped manner, the receiving width W2 of the guide member 15 is maximized. Pachinko balls that have not won in the big winning opening 5 that is opened in the big hit state are received in the receiving area V of the guide member 15 and directly enter the lower winning opening 28. In the case of the pachinko gaming machine 100 according to the present embodiment, a process of paying out one ball is performed by winning a prize in the lower prize opening 28 (multiple return). This processing corresponds to the compensation processing when the big winning opening 5 is not won in the big hit state. Thereby, the disappointment felt by the player when the ball does not win the big winning opening 5 in the big win state is resolved by the variable winning device 201.

<Probability change state (third state)>
And when it becomes a certain change state after the big hit by a predetermined jackpot symbol, the guide member 15 of the variable winning device 201 is controlled from the second state to the third state (third control). Changes in the shape of the guide member 15 at that time are shown in FIGS. That is, as shown in FIG. 8A, only the motor shaft 16a of the first control motor 16 of the first and second control motors 16 and 17 of the guide member 15 arranged in the second state. Is rotated in a predetermined direction. As a result, as shown in FIG. 8B, the right upright plate portion 18 moves toward the center, and the bottom plate pieces 19a, 19b of each step are also slid in the left-right direction and offset in a stepped manner. A step shape is formed, and the receiving width W3 of the guide member 15 is reduced. Moreover, since the lower winning opening 28 is covered and covered by the bottom plate piece 19a of each step, the ball received by the guide member 15 stays as it is. Further, since the left standing plate portion 18 is stationary, the receiving width W3 of the guide member 15 in the third state is narrower than the receiving width W2 of the guide member 15 in the second state, and flows down the lower game area 2a. Not all balls are received by the guide member 15.

  After this state is maintained for a predetermined time, the motor shaft 16a of the first control motor 16 is rotated in the reverse direction, and the right upright plate portion 18 moves in the right direction. As shown in FIG. 8C, the guide member 15 is again arranged in the second state. When the guide member 15 is in the third state, the ball received by the guide member 15 wins the lower prize opening 28.

  Subsequently, only the motor shaft 17a of the second control motor 17 of the guide member 15 is rotated in a predetermined direction. As a result, as shown in FIG. 8 (d), the left upright plate portion 18 moves toward the center, and the bottom plate pieces 19a, 19b of each step are also slid in the left-right direction and offset in a step shape. A step shape is formed, and the receiving width W3 of the guide member 15 is reduced. Since the operation at this time is exactly the same as in the case of FIG. After a predetermined time has elapsed, the guide member 15 is arranged in the second state (the state shown in FIG. 8A), and the above-described operation is repeated during the probability change state.

  When the probability changing state of the pachinko gaming machine 100 ends, the guide member 15 is in the first state and is reciprocated in the left-right direction.

  When the guide member 15 of the variable winning device 201 is disposed in the first state or the third state, the pachinko balls that have flowed down to the lower game area 2a and have not been received by the guide member 15 are discharged through the out port 9. Is done.

<Modification of Probability Change State (Third State)>
Next, a modified example of the action of the guide member 15 in the probability variation state (third state) will be described with reference to FIG. The operation described above is a case where the guide member 15 is switched between the second state and the third state. However, as shown in FIG. 9, the guide member 15 may be switched between the first state and the third state. That is, as shown in FIG. 5, the motor shafts 16a and 17a of the first and second control motors 16 and 17 of the pair of upright plate portions 18 of the guide member 15 arranged in the second state are opposite to each other. Is rotated. Thereby, as shown to (a) of FIG. 9, a pair of upright board part 18 approaches, and the guide member 15 is arrange | positioned in a 1st state. After the elapse of a predetermined time, only the motor shaft 16a of the first control motor 16 is rotated in a predetermined direction, the right upright plate portion 18 is moved in the right direction, and the receiving width W3 of the guide member 15 is increased. As in the case described above, the ball received by the guide member 15 stays as it is.

  After the third state of the guide member 15 is maintained for a predetermined time, the motor shaft 16a of the first control motor 16 is rotated in the reverse direction so that the right upright plate portion 18 approaches the left upright plate portion 18. The guide member 15 is once arranged in the first state (FIG. 8C). At this time, since the bottom plate pieces 19a and 19b of the respective stages are also slid, the balls staying in the guide member 15 are pushed up to win the upper prize opening 27.

  Subsequently, only the motor shaft 17a of the second control motor 17 is rotated in a predetermined direction, and only the left upright plate portion 18 is moved in the left direction, so that the receiving width W3 of the guide member 15 is increased. The operation at this time is exactly the same as in the case of FIG. After a predetermined time has elapsed, as shown in FIG. 8A, the guide member 15 is again placed in the first state, and the balls received by the guide member 15 win the upper prize opening 27. Then, the above operation is repeated.

  As described above, the guide member 15 of the variable winning device 201 of this embodiment is controlled so as to be arranged in the first to third states. Therefore, the guide member 15 can be arranged by combining the first to third states. And it is also possible to arrange | position the guide member 15 of each state other than an above-described position. For example, as shown in FIG. 10, the guide member 15 in the third state may be disposed at substantially the center of the lower game area 2a.

  In any of the cases described above, the variable winning device 201 according to the present invention is provided not only between the guide member 15 reciprocating in the left-right direction but also between the pair of upright plate portions 18 constituting the guide member 15. The formed bottom plate portion 19 also slides as the pair of upright plate portions 18 approaches and separates. Thereby, the guide member 15 is arranged in any state from the first state to the third state. When the guide member 15 is reciprocatingly moved in the first state (first control), the player performs a thrilling and varied game as to whether or not the ball is received by the guide member 15 in the first state. Can do. When the guide member 15 is placed in the second state (second control), the player receives all the balls that have not entered the big prize opening 5 into the guide member 15 and wins the lower prize opening 28. So you can feel a sense of security and joy. Further, when the guide member 15 is arranged in the third state in the certain change state (third control), many balls are received by the guide member 15 and have the same function as the start winning opening 4. Since the upper prize opening 27 is won, the player can quickly realize the next jackpot.

  In the variable winning device 201 of the first embodiment described above, the guide member 15 is reciprocated in the left-right direction by the first and second control motors 16 and 17. Next, the variable winning device 202 of the second embodiment will be described. As shown in FIGS. 11 and 12, a nut member 29 is attached to the protruding portion 18 a of each upright plate portion 18, and a screw rod (for example, a ball screw 31) is fitted and attached to the nut member 29. Yes. Ends of the ball screw 31 are connected to motor shafts 32 a and 33 a of the first and second control motors 32 and 33. When the motor shafts 32a, 33a of the control motors 32, 33 are reciprocated in a predetermined direction, the guide member 15 is reciprocated in the left-right direction. In FIG. 11, the heights of the ball screws 31 connected to the motor shafts 32 a and 33 a of the first control motor 32 and the second control motor 33 are made different in order to avoid interference. In FIG. 11, reference numeral 34 denotes a support member for the ball screw 31. In the case of the variable winning device 202 of the second embodiment, since the motor shafts 32a, 33a of the control motors 32, 33 are arranged along the moving direction of the guide member 15, the guide member 15 is moved smoothly. There is an advantage that can be.

  Further, the guide member 15 may be reciprocally moved by the chain 35 and the chain gear 36 as in the variable winning device 203 of the third embodiment shown in FIG.

  As described above, the variable winning devices 201 to 203 according to the present invention have a configuration in which one guide member 15 reciprocates in the lower game area 2a and the bottom plate portion 19 constituting the guide member 15 expands and contracts. Since two configurations in which the winning probability changes are realized at the same time, it is possible to allow the player to play the game with unexpectedness that has not existed before, and to provide new interest.

  And it is also possible to modify as follows.

  Although the control of the guide member 15 of the variable winning devices 201 to 203 is changed according to the game state, the control may be changed under any conditions. For example, the control is changed every time the winning at the start winning opening 4 is counted five times, the control is changed when winning a specific winning opening, the control is changed every time a predetermined time elapses, Alternatively, the control can be changed depending on the number of winnings to the upper winning port 27 and the lower winning port 28.

  When the guide member 15 is switched from the first state to the second state, the pair of upright plate portions 18 of the guide member 15 disposed substantially at the center in the left-right direction in the lower game area 2a are simultaneously separated to the second state. Can be migrated. In addition, in a state where any one of the standing plate portions 18 of the guide member 15 is disposed at the end of the lower game area 2a, only the other standing plate portion 18 can be separated and shifted to the second state.

  Although only the probability change state is illustrated as the special game state, it may be a pachinko gaming machine that can generate any other game state such as a short-time state, or the control change target of the variable winning devices 201 to 203. You may do it.

  As the winning process to the upper winning port 27 and the lower winning port 28, the start winning and the same-time return are illustrated, but any other winning process may be performed. For example, the number of winning balls may be different from that in the embodiment, the jackpot lottery processing may be performed with a jackpot probability different from the winning at the start winning opening 4, the symbol variation in the symbol display unit 3 may be stopped, or the special game state It may be possible to move to Of course, the same winning process may be performed.

  Although there are two upper and lower winning openings, one may be used. Moreover, the numerical value of the inclination angle of the upper surface of the bottom plate pieces 19a, 19b is an example, and any numerical value may be used.

  The variable winning devices 201 to 203 may be arranged on the upstream side of the big winning port 5. For example, the variable winning devices 201 to 203 may be arranged at the position of the start winning opening 4. In this case, the start winning process may be performed with different jackpot probabilities using the upper and lower winning holes 27 and 28 as starting winning holes.

  After the guide member 15 is in the third state, control is performed to shift to the first state or the second state within a predetermined time (for example, 3 seconds). For example, it may be shortened according to the winning prize to the start winning opening 4. Thereby, the problem that a ball overflows from the receiving area V of the guide member 15 in the third state can be avoided. The predetermined time mentioned above can be made shorter than the time for which the guide member 15 is held in the second state, for example.

  In order to stabilize the operation of the bottom plate piece 19c in the lowermost stage, the back portion of the bottom plate piece 19c may be extended and guided to the guide groove 22. Further, although the guide groove 22 is disposed below the pair of upright plate portions 18, it may be disposed above. Further, the two guide grooves 22 may be arranged up and down.

  In the jackpot state, control can be performed by distinguishing between the second control and the first control that does not move, depending on the type of jackpot (a normal jackpot and a jackpot with certainty). Thereby, the hitting ball in the big hit can be adjusted by the nail adjustment.

  The lower lower game area 2a of the pachinko gaming machine 100 of this embodiment is narrower in the left-right direction than the upper game area 2. However, the width of the lower game area 2a may be approximately the same as the width of the upper game area 2.

  In the pachinko gaming machine 100 according to the present embodiment, the bottom plate pieces 19a and 19b of the bottom plate portion 21 are provided in a plurality of stages, and are configured to expand and contract in a stepped manner. However, the bottom plate pieces 19a and 19b may have a single stage and extend and contract in a pantograph shape or a telescope shape. Further, the bottom plate pieces 19a, 19b may be made of a rubber material that can expand and contract.

  There may be provided transition determining means for determining whether to perform control to switch to either the first state or the second state after the guide member 15 is in the third state based on the predetermined condition. Then, it may be determined based on a predetermined condition whether the guide member 15 is switched from the third state to the first state or the second state. The predetermined conditions include lottery based on winning statuses such as different gaming states (for example, whether it is a probable change state or a short-time state), the previous winning winning port 4, the upper winning port 27, the lower winning port 28, etc. The game time may be determined based on the game time (for example, switching to the second state in the evening and switching to the first state just before closing). Alternatively, the predetermined condition may be switched to be biased to one of the first and second states in accordance with the establishment of the predetermined condition (for example, when the number of symbol fluctuations after the big hit becomes a predetermined number or more). Furthermore, you may provide the alerting | reporting means which notifies a player to which state it switches to.
