JP 2013-192619 A JP 2012-245173 A

Here, in the conventional big prize opening device described above, since the specific area is arranged at a position away from the big prize opening, a passage for guiding the game ball flowing into the big prize opening to the specific area is provided. However, if such a passage is provided, the structure of the entire variable prize-winning device is increased. However, there is a case where such a large prize opening device cannot be installed due to the relationship with other objects placed on the game board. As a result, the movement space becomes narrow, which may cause problems such as ball clogging and double sensor detection.
In view of the above circumstances, an object of the present invention is to provide a gaming machine provided with a big prize opening device that is compact and hardly causes ball clogging or the like.

In order to achieve the above-described object, the present invention has the following configuration.
That is, the gaming machine (pachinko machine P) according to the present invention is provided in the gaming area 120 where the gaming ball flows down, and in the gaming area 120, and in a closed state in which it is difficult to enter or cannot enter the gaming ball, A variable winning device (second large winning opening device 1B) having an openable and closable member 41 that is displaceable to an open state in which a game ball can be easily entered. A first detection unit 60 for detecting, and a second detection unit 70 capable of detecting a game ball that has passed through the first detection unit 60, and based on the detection of the game ball by the second detection unit 70, the game ball Is treated as having passed through the specific region 13.
In the present invention, the second detection unit 70 is arranged in the vertical direction of the first detection unit 60, and the flow path of the game ball from the first detection unit 60 to the second detection unit 70 is When the projecting state closes above the second detection unit 70, the game ball that has passed through the first detection unit 60 is received, and the region other than the second detection unit 70 (general region 12) is received. When the game ball is guided and the upper part of the second detection unit 70 is opened, the game ball that has passed through the first detection unit 60 is allowed to flow down to the second detection unit 70. A distribution member (distribution plate 51) is provided, and the upper surface of the distribution member is in contact with the game ball flowing down from the first detection unit 60, and the flow direction of the game ball is set to the other region. A direction restricting portion (curved surface 51B) that can be restricted in the direction is formed. To.

In the present invention, the second detection unit 70 that becomes the specific region 13 is arranged directly below the first detection unit 60 that detects the game ball that has entered the variable winning device, and a sorting member is interposed between the two detection units. Thus, the game balls are distributed to the specific area 13 and other areas. When the sorting member is in the protruding state, the game ball that has passed through the first detection unit 60 abuts on the direction regulating unit of the sorting member, changes direction, and flows down in the direction of another region.
According to the present invention, since the second detection unit 70 is disposed directly below the first detection unit 60, if the sorting member is in the retracted state, the game ball that has passed through the first detection unit 60 is directly detected as the second detection unit 60. Therefore, it is not necessary to provide a passage for guiding the game ball from the first detection unit 60 to the second detection unit 70.

  Even if the distance between the first detection unit 60 and the second detection unit 70 is made as small as possible, and as a result, the distance between the first detection unit 60 and the upper surface of the sorting member is reduced, the direction regulating unit As a result, it is prevented as much as possible that the game ball bounces upward and double detection occurs in the first detection unit 60, or the bounced game ball does not flow down well to other areas and causes clogging of the ball. can do. In other words, it is possible to reduce the distance between the first detection unit 60 and the second detection unit 70 by providing the direction restricting unit on the distribution member, and as a result, the variable winning device itself can be downsized. Is possible.

  Here, an inclined surface 51A that is inclined downward toward the other region is provided on the upper surface of the distribution member, and the direction restricting portion is continuous with the inclined surface 51A and extends in the downward direction of the inclined surface 51A. It can be set as the curved surface 51B formed so that height may increase toward the opposing up direction side. When formed in this way, the game ball whose direction has been changed by the direction restricting portion can be smoothly flowed down to another region. Further, the impact applied to the sorting member can be reduced as compared with the case where the game ball is received on a flat surface, and the sorting member can be prevented from being damaged.

  According to the present invention, it is possible to provide a gaming machine provided with a large prize opening device that is less likely to cause ball clogging even with a compact structure.

(Outline of the game)
In the pachinko machine P according to the present embodiment, the game balls that are launched by a launching device (not shown) and flow down the game area 120 are the general winning opening 140, the first starting winning opening 150, and the second starting winning opening. When entering 160, a predetermined number of prize balls are paid out. In addition, when a game ball enters the first start winning opening 150 and the second starting winning opening 160, whether or not to execute a special game in which the first big winning opening 170 and the second big winning opening 180 are opened. A jackpot lottery for determining whether or not a special symbol corresponding to the result of the jackpot lottery is determined. When the jackpot is won by the jackpot lottery, a special game is executed in which a round game in which one of the first jackpot 170 and the second jackpot 180 is opened and closed is performed a predetermined number of times. When a game ball enters the first grand prize opening 170 or the second grand prize opening 180, a predetermined number of prize balls are paid out. In addition, one round game is started by opening the first grand prize opening 170 or the second big prize opening 180, and a predetermined time (for example, 29 seconds) has elapsed after the start, or a predetermined number (for example, for example) If any one of the conditions in which the entry of ten (10) game balls is detected, the first grand prize opening 170 or the second big prize opening 180 is closed. Then, the next round game is started after a predetermined interval period (for example, 2 seconds).

Here, as described above, a special symbol is determined according to the result of the jackpot lottery, but when winning the jackpot, one of the multiple types of special symbols associated with the jackpot winning One special symbol is determined by lottery. Each special symbol has a predetermined number of round games (number of rounds) executed during the special game. The number of rounds may be one or more. In addition, the timing and the number of times to open the first grand prize opening 170 and the second big prize opening 180 are determined in advance according to the number of rounds.
For example, in the case of a big hit of 10 rounds, only the first grand prize opening 170 is opened and the second big prize opening 180 is not opened from the 1st to the 7th rounds, and the 8th and 9th rounds are the 2nd largest. Only the winning opening 180 is not opened and the first big winning opening 170 is not opened, but only the first big winning opening 170 is opened again in the tenth round. In the case of a big hit of five rounds, only the first big prize opening 170 is opened until the first to fourth rounds, and only the second big prize opening 180 is opened for the fifth round.

  Further, in the present embodiment, when the second grand prize winning opening 180 is opened during the special game, when the game ball is guided to the specific area 13, the special game is terminated by a lottery lottery. It is set to shift to a high probability state where the probability of winning the jackpot is higher than the normal state. In addition, the special pattern is associated with an operation pattern that is a pattern of the distribution board 51, and the operation pattern of the distribution board 51 makes it easy for the distribution board 51 to enter the game ball in the specific area 13. There are a pattern that operates in such a manner and a pattern that operates so that a game ball hardly enters the specific area 13. When the special symbol associated with the pattern that operates so that the game ball can easily enter is selected, the second big prize opening 180 is opened and the distribution board 51 is operated, so that the game ball is When a special symbol associated with a pattern that is guided to the specific area 13 and operates so as to make it difficult to enter the game ball is selected, the second big prize opening 180 is opened and the distribution board 51 is activated. Even so, the game ball is hardly guided to the specific area 13.

  When a game ball enters the first start winning opening 150, a special symbol display is performed over a predetermined time on a first special symbol display device (not shown), and the game ball is input to the second start winning opening 160. When the ball enters, the second special symbol display device (not shown) displays the variation of the special symbol over a predetermined time. During this time, the effect display device 210 performs a change effect. And after progress of predetermined time, the fluctuation | variation display of a 1st special symbol display apparatus or a 2nd special symbol display apparatus stops, and the special symbol which shows the result of jackpot lottery is stopped and displayed. In the case of winning the jackpot lottery, the special symbol determined corresponding to the jackpot is stopped and displayed, and in the case of a loss, the special symbol determined corresponding to the loss is stopped and displayed. In the effect display device 210, the symbol variation is stopped and the symbol corresponding to the lottery result is stopped and displayed. When the special symbol associated with the special game is displayed in a stopped state, the special game is started.

  In addition, if a game ball enters the first start winning port 150 or the second starting winning port 160 while the special symbol is being displayed or during the execution of the special game, this is indicated. It is stored (held), and the number of special symbols held is displayed on a predetermined hold display section. Then, when the special symbol variation display is finished or the special game is finished, the jackpot lottery and the special symbol lottery are performed based on the hold. Up to 4 holds can be stored, and if the jackpot lottery or special symbol lottery is performed based on the hold, the number of holds will be reduced, and accordingly the display of the number of reserved special symbols on the hold display will also be reduced .

  In addition, when the game ball passes through the gate 200, a lottery is performed as to whether or not the movable start 161 provided in the second start winning opening 160 is opened and the second starting winning opening 160 is opened. This lottery is performed as a normal symbol lottery in which one normal symbol is determined from a plurality of types of normal symbols respectively associated with opening (winning) and non-opening (losing) of the second start winning opening 160. If the lottery result is a win, the movable piece 161 is in an open state for a predetermined time, and the second start winning opening 160 is opened.

  When the game ball passes through the gate 200, the normal symbol display is performed over a predetermined time in a normal symbol display device (not shown). Then, after the variation time has elapsed, the variation display of the ordinary symbol display device 320 is stopped, and the ordinary symbol indicating the result of the lottery of the ordinary symbol is stopped and displayed. That is, in the case of winning, the normal symbol determined corresponding to the winning is stopped and displayed, and in the case of loss, the normal symbol determined corresponding to the lost is stopped and displayed. When the normal symbol determined corresponding to the winning is stopped and displayed, the second start winning opening 160 is opened. When the second start winning opening 160 is opened, more game balls can be made to enter the second start winning opening 160, and the chance of receiving a jackpot lottery increases. It is possible to make the state more advantageous than when the is not opened.

  If a game ball passes through the gate 200 while the normal symbol display is being performed on the normal symbol display device, a maximum of four symbols are held as in the case of the special symbol, and a predetermined hold display is made. The number of normal symbols on hold is displayed in the section. When the normal symbol variation display ends, the normal symbol lottery is performed based on the hold, and the number of holds is reduced and the display of the number of hold of the normal symbols in the hold display portion is also reduced.

  Here, in the pachinko machine P according to the present embodiment, the game ball flowing down the first game area 121 can enter the first start winning opening 150 and the game flowing down the second game area 122. The ball can pass through the gate 200, enter the second start winning opening 160, and enter the first large winning opening 170 and the second large winning opening 180. When the special game is not in progress, in order to enter the game ball into the first start winning opening 150, the player is caused to launch the game ball into the first game area 121 (so-called left-handed), and during the special game During the high probability state, the player enters the second game area 122 in order to enter the game ball into the first grand prize winning hole 170 and the second big prize winning hole 180 or the gate 200 and the second starting prize winning hole 160. The game ball is launched (so-called right-handed). Specifically, during the special game and the high probability state, the effect display device 210 displays an instruction to launch a game ball into the second game area 122, and the special game or the high probability state ends. In the effect display device 210, a display for instructing to return to the launch of the game ball into the first game area 121 is performed.

As shown in FIG. 5, when the projecting pin 41A is located near the lower end of the long hole 31, the opening / closing member 41 is in a closed state in which the game ball cannot be received from the opening 11, and FIG. As shown, when the protruding pin 41 </ b> A is positioned near the upper end of the long hole 31, the opening / closing member 41 is formed to be in an open state in which a game ball can be received from the opening 11. In addition, the opening / closing member 41 comes into contact with a part of the partition wall 23B which is the lower wall of the opening 11 in the partition wall 23 of the front cover 20, and can be maintained in a closed state or an open state. Yes.

As shown in FIG. 8, the link member 44 is an arm-like member bent in a bowl shape, and is fixed to the movable shaft 43 </ b> A of the opening / closing solenoid 43, and fixed to the bent portion through the support shaft 45.

The distribution plate 51 is a plate member that can pass through a slit 31 </ b> B (see FIGS. 5 and 6) provided on the front surface 31 of the base 30 and protrude into the space above the second detection unit 70 (specific region 13). is there. As shown in FIG. 12, the top surface of the distribution plate 51 has an inclined surface 51A inclined downward from the right side to the left side (general region 12 side) when viewed from the front, and the right side (general region 12 of the general region 12) continuously from the inclined surface 51A. The curved surface 51B increases in height toward the opposite side, that is, the upward direction side facing the downward direction of the inclined surface 51A.

Here, the radius of curvature of the curved surface 51B is formed larger than the radius of the game ball, and the game ball flowing down from the first detection unit 60 abuts on the position p1 shown in FIG. Bounces in the direction of α. The tangent L1 of the curved surface 51B at p1 has a larger inclination angle than the line L2 obtained by extending the inclined surface 51A of the distribution plate 51. If the upper surface of the distribution plate 51 is formed only by the inclined surface 51A, the game ball abuts on the position p2 and rebounds in the direction of β, so that the game ball is formed by forming the curved surface 51B. It is possible to loosen the angle at which the ball hits the upper surface of the distribution plate 51 and bounces back.
Further, a chamfered portion 51 </ b> C is formed at the front end portion of the distribution plate 51 from the front side toward the back side. That is, the front end portion of the distribution plate 51 is sharp. This reduces the contact surface between the front end portion of the distribution plate 51 and the game ball as much as possible so that the game ball is not sandwiched between the distribution plate 51 and the back surface of the front plate 21 of the front cover 20. It is to do.

Further, a swinging member 54 is attached to the moving member 52 via a connecting shaft 56. As shown in FIG. 6, the swing member 54 is swingably attached to the fixed frame 50 </ b> A via the swing shaft 55, and at the middle of the connecting shaft 56 and the swing shaft 55, It is connected to the movable shaft 53A.

  When the distribution solenoid 53 is in a non-energized state, as shown in FIG. 6, the swing member 54 is almost upright, and the distribution plate 51 protrudes from the slit 31 </ b> B to the space above the specific region 13. It is in the protruding state. That is, the specific area 13 is blocked by the distribution plate 51 blocking the flow-down passage of the game ball. Further, when the distribution solenoid 53 is energized, as shown in FIG. 11, the swinging member 54 rotates about the swinging shaft 55 and tilts backward as the movable shaft 53A moves. The moving member 52 moves backward while being guided by the guide groove 58. Along with this, the distribution plate 51 also moves rearward and enters a retracted state in which it is immersed inside the slit 31B (the back side of the front plate 31). As a result, the specific area 13 is opened.

  As shown in FIG. 6, the second big prize opening device 1 </ b> B is configured such that the opening / closing mechanism 40 and the distribution mechanism 50 fixed to the base 30 are housed in the opening 110 </ b> A provided in the game board 110. The 30 front plates 30 </ b> A are fixed from the front side of the game board 110, and the outlet member 35 is fixed to the base 30 from the back side of the game board 110 to be attached to the game board 110.

(Operation of the second grand prize opening device 1B)
In the second grand prize opening device 1B, the open / close solenoid 43 and the distribution solenoid 53 are normally de-energized, the second big prize opening 180 is closed, and the specific area 13 is shielded by the distribution plate 51. Has been. Then, during the special game, when the second round winning opening 180 is opened in a specific round, the open / close solenoid 43 is energized and the open / close member 41 is opened. The game ball that has flowed into the second big prize opening 180 (opening 11) is first detected by the first detection unit 60, and a predetermined prize ball is paid out based on this detection signal.

  When the opening / closing member 41 is in the open state, the energization of the sorting solenoid 53 is controlled according to the operation pattern of the sorting plate 51 corresponding to the special symbol related to the special game. For example, in the case of a pattern that operates so that a game ball can easily enter, the distribution plate 51 enters a retracted state after a predetermined time (for example, 3 seconds) and then protrudes after a predetermined time (for example, 22 seconds). Thus, the distribution solenoid 53 is energized. In such an operation pattern, the specific area 13 is released for a certain length of time, so that it becomes easy for a game ball to enter the specific area 13. In the case of a pattern in which the game balls are operated so as to be extremely difficult to enter, the distribution plate 51 is in a retracted state after a predetermined time (for example, 10 seconds), and then the predetermined time (from the launching interval of the game balls by the launching device). In other words, the sorting solenoid 53 is energized so that the protruding state is reached after a short time (eg, 0.3 seconds). In such an operation pattern, since the time for which the specific area 13 is opened is extremely short, the possibility that a game ball enters the specific area 13 is extremely low. The operation pattern of the distribution plate 51 described above is an example, and is not limited to the above-described mode. For example, an operation pattern in which the sorting plate 51 is in a retracted state a plurality of times during one round may be used.

When the distribution board 51 is in the retracted state, the game ball that has passed through the first detection unit 60 flows down to the second detection unit 70 as it is, and thus the ball entering the specific area 13 is detected. Thereby, the transition to the high probability state after the end of the special game is guaranteed. On the other hand, when the distribution plate 51 is in the protruding state, the game balls that have passed through the first detection unit 60 are blocked by the distribution plate 51 and do not flow down to the second detection unit 70. Since the distribution board 51 is inclined downward toward the third detection unit 80 (general area), the game balls hitting the distribution board 51 are guided to the general area.
When a predetermined round end condition for opening the second big prize opening 180 is met, the open / close solenoid 43 is turned off and the open / close member 41 is closed. Along with this, the distribution solenoid 53 in the energized state is brought into a non-energized state, and the distribution plate 51 in the retracted state is brought into a protruding state.

(Summary)
As described above, in the present embodiment, in the second grand prize opening device 1B, the second detection unit 70 serving as the specific region 13 is disposed immediately below the first detection unit 60, and the detection of the first detection unit 60 is performed. The region and the specific region 13 are formed so as to be positioned substantially on the vertical line, and the third detection unit 80 that becomes the general region 12 is disposed adjacent to the second detection unit 70, and the first detection unit 60 and the second detection unit are arranged. The distribution board 51 is arranged between the game unit 70 and the game balls that have passed through the first detection unit 60 are distributed to the general area 12 or the specific area 13 by the appearance of the distribution board 51. The distribution plate 51 has an inclined surface 51A that is inclined downward in the direction of the general region 12, and a portion that receives a game ball flowing down from the first detection unit 60 is continuous with the inclined surface 51A. The curved surface 51 </ b> B is formed so as to increase in height toward the opposite side of the general region 12.

By making the distribution plate 51 into such a shape, the game ball that has passed through the first detection unit 60 abuts on the distribution plate 51 and does not bounce upward (see FIG. 12B), so that the general It can flow down in the direction of region 12. Thereby, even if the distance between the 1st detection part 60 and the 2nd detection part 70 is shortened and the distance of the 1st detection part 60 and the distribution board 51 is shortened, the game bounced off by the distribution board 51 Double detection in which the sphere is detected again by the first detection unit 60 and clogging caused by the rebounded game ball not flowing well in the direction of the general area 12 can be prevented.
For example, in the present embodiment, the distance (H1 shown in FIG. 12A) from the vertical center position of the first detection unit 60 to the vertical center position of the distribution plate 51 is calculated from the diameter of the game ball. The distance is set to be slightly larger, and the distance from the vertical center position of the first detection unit 60 to the vertical center position of the second detection unit 70 (H2 shown in FIG. 12A) is made as short as possible. . The distance between the first detection unit 60 and the second detection unit 70, the distance between the third detection unit 80 and the distribution plate 51, and the curvature of the curved surface 51B of the distribution plate 51 are as follows. According to conditions such as the performance of the sensor used as the detection unit and the material of the distribution plate 51, it should be appropriately set so as to obtain the above-described effects.

In addition, a curved surface 51B continuous with the inclined surface 51A is used as the direction restricting portion for changing the flow direction of the game ball toward the general region 12 in the portion where the game ball first hits in the distribution board 51. Thus, the game ball whose direction has been changed in contact with the curved surface 51 </ b> B can be smoothly moved on the upper surface of the distribution plate 51. Further, by receiving the game ball on the curved surface 51B, it is possible to reduce the impact applied to the distribution plate 51 as compared with the case where the game ball is in contact with the flat surface, and it is difficult to damage the distribution plate 51. it can.

Here, in the above-described embodiment, the distribution plate 51 is formed so as to move in the front-rear direction to open and close the specific area 13, but the side of the specific area 13 (right side in front view in the above embodiment). If there is a room in the space, the distribution plate 51 may move in the left-right direction to open and close the specific area 13. That is, in the normal state, the distribution plate 51 is in a protruding normal state that covers the second detection unit 70 from the upper side, and in a specific case, the distribution plate 51 may move to the right side and enter the retracted state. .
In the above-described embodiment, the direction restricting portion is the curved surface 51B that is concave when viewed from the front. However, an inclination angle that can change the direction of the game ball toward the general region 12 (for example, FIG. It may be an inclined surface (flat surface) inclined at an angle of L1 in B). Or it is good also as a curved surface which becomes convex shape in front view.

Furthermore, the present invention can be applied to a so-called pachinko machine called so-called wings, which has a specific area inside the special winning opening and a special game is started when a game ball passes through the specific area. it can.
