The second interlocking member 88 is locked in the closed state X of the opening / closing member 48 after engaging with the engaging portion 92, and then comes into contact with the contacted portion 95.

  In addition, when the second contact portion 97 is separated from the contacted portion 95 when the opening / closing member 48 is positioned in the closed state X and is regulated by the front restricting means 80, interference with the contacted portion 95 is avoided. An escape portion may be provided and the third contact portion 98 may be omitted. Further, even when the contact guide portion 93 a contacts the engaged portion 92 and the opening / closing member 48 is positioned in the closed state X, the third contact portion 98 is substituted for avoiding interference with the contacted portion 95. An escape portion may be provided.

  When the opening / closing member 48 is in the closed state X, the first abutting portion 96 and the abutted portion are not contacted so that the interlocking members 86 and 88 do not cooperate until the locking means 51 is released when the first interlocking member 86 is retracted. A predetermined interval is provided in the front-rear direction between the portion 95.

  As shown in FIGS. 4 and 6, the front restricting means 80 includes a pair of left and right engaging protrusions 99 that protrude downward from the vicinity of both left and right ends of the rear wall 91 of the opening / closing member 48, and a passage wall 66 of the guide passage 57. On both the left and right sides of the sliding guide portion 74, the opening and closing member 48 has an engaging portion 100 which is formed in a recessed shape from the back side in the vicinity of the inside of each sliding guide portion 74 and the engaging protrusion 99 is detachably engaged from the back side. In the closed state X, the engaging protrusion 99 is engaged with the engaging portion 100 from the back side and is urged forward by an urging means such as a return spring of the driving means 49.

  As shown in FIGS. 4 and 7, the rear regulating means 81 is a pair of left and right formed in a rearwardly spreading manner between the rear wall portion 91 of the rear end of the opening / closing member 48 and the base portion of each engaged portion 90. A front inclined portion 101 and a rear inclined portion 102 which is provided in the rear case 54 so as to rise forward and contacts the front inclined portion 101 from above; 102 abuts in an intersecting manner. FIG. 7 shows the open / close member 48 in the open state Y.

  During the game, the player operates the launching means to launch a game ball into the game area 12. At this time, if it is a normal probability state, the player hits the left so that the game balls concentrate on the left-handed passage 24 which is easy to win the first special symbol starting means 15. If the first special symbol starting means 15 wins while the game ball falls down through the left-handed passage 24, the first special symbol of the first special symbol display means 21 and the effect symbol 37a of the effect symbol display means 37 are displayed. ~ 37c fluctuate for a predetermined time in synchronization. Then, depending on whether or not the lottery result when the game ball wins the first special symbol starting means 15 is a big hit, the first special symbol after the fluctuation of the first special symbol display means 21 is a big hit mode or a miss The effect symbols 37a to 37c of the effect symbol display means 37 are stopped in the jackpot effect mode or the off effect effect mode.

  If the game ball that has entered the right-handed path 25 wins the normal symbol starting means 14 even in the normal probability state, the normal symbol of the normal symbol display means 20 may fluctuate and stop in a winning manner after the fluctuation. However, since the opening time of the second special symbol starter 16 is very short during the normal probability state, the possibility that a game ball wins the second special symbol starter 16 is very low.

  If the first special symbol after the change of the first special symbol display means 21 stops in a big win mode, it becomes a big hit state, and the first open / close-type winning means 17 repeats the opening / closing operation for a predetermined number of rounds with a predetermined open / close pattern. The player hits the first opening / closing type winning means 17 to make a right strike to concentrate the game ball on the right strike passage 25 side where the game ball is easy to win.

  The game balls that have entered the right-handed passage 25 fall downward through the normal symbol starting means 14, the ball guide plate 28, and the like, and then some of the game balls travel downward through the passage 42 on the right side of the inclined portion 62. The remaining game balls flow down to the first opening / closing type winning means 17 side to the left of the inclined portion 62.

  In the first open / close-type winning means 17, the open / close member 48 is normally positioned in the closed state X as indicated by the solid line in FIG. 4 by the biasing means such as the front regulating means 80 and the return spring in the solenoid 84. The winning opening 47 is closed by the inclined upper surface portion 72.

  At this time, the opening and closing member 48 is locked in the closed state X by the locking means 51 of the interlocking means 50, and even if an impact such as striking the glass door 4 in the front-rear direction is applied, the opening and closing member 48 is thereby closed. There is no fear of moving from Y to open state Y.

  That is, when the solenoid 84 of the driving means 49 is in a demagnetized state, the plunger 85 and the first interlocking member 86 are advanced by the return spring, and as shown in FIG. The engaging portion 93 of the first interlocking member 86 engages with the engaged portion 92 of the second interlocking member 88 from below, and the locking means 51 brings the opening / closing member 48 into the closed state X via the second interlocking member 88. Locked.

  Therefore, even if a backward external force (a direction indicated by arrow) acts on the opening / closing member 48 to rotate the second interlocking member 88 about the pivot 87 in the direction indicated by the arrow b, the second interlocking member 88 is locked by the locking means 51. Is restricted from rotating, so that the opening / closing member 48 is illegally opened by striking the glass door 4 etc. at the timing when the game ball falls near the upper side of the first open / close winning means 17. Cheating can be prevented.

  When the solenoid 84 of the driving means 49 is excited, the plunger 85 and the first interlocking member 86 start the retreating operation in the direction of arrow a against the return spring, and from the position shown in FIG. Move as shown in C). However, when the opening / closing member 48 is in the closed state X, there is a large gap in the front-rear direction between the first contact portion 96 and the contacted portion 95 of the cooperation means 52 shown in FIG. The second interlocking member 88 remains stopped in the closed state X of the opening / closing member 48 even if the reverse movement starts.

  Then, as shown in FIG. 11A, the first interlocking member 86 moves backward until the first contact portion 96 of the cooperation means 52 contacts the contacted portion 95 and cooperates. 93 moves rearward and disengages from the engaged portion 92, and the locking means 51 unlocks the second interlocking member 88 in the closed state X of the opening / closing member 48.

  When the engaging portion 93 is disengaged from the engaged portion 92 and the lock of the second interlocking member 88 is released, the first contact portion 96 of the cooperation means 52 contacts the contacted portion 95 and the first interlocking portion is engaged. The member 86 and the second interlocking member 88 are in a cooperative state. For this reason, when the first interlocking member 86 is further retracted in the direction indicated by the arrow a, the second interlocking member 88 is moved around the pivot axis 87 via the cooperation means 52 as shown in FIGS. 11B and 11C. The opening / closing member 48 moves backward in the direction indicated by the arrow a until the open state Y as shown by a two-dot chain line in FIG.

  When the winning opening 47 is thus opened, the game ball that has entered to the left of the top of the inclined portion 62 wins the winning opening 47 while being blocked by a game nail or the like. For example, a game ball dropped on the inclined portion 62 is guided by the inclined portion 62 and enters the winning opening 47, and is guided from the inclined portion 56b of the bottom wall portion 56 to the guide passage 57 through the guide groove 56a. Then, the ball passes through the ball detection switch 58 and passes to the back side of the game board 10.

  For example, when the ball detection switch 58 detects winning of 10 game balls or when a predetermined time has elapsed after the opening / closing member 48 is opened, the solenoid 84 of the driving means 49 is demagnetized and the plunger 85 is moved by the return spring. Therefore, the opening / closing member 48 advances to the closed state X via the interlocking members 86, 88, and the inclined upper surface portion 72 closes the winning opening 47.

  When the opening / closing member 48 is in the open state Y, the contacted portion 95 of the linkage means 52 is between the first contact portion 96 and the second contact portion 97 as shown in FIG. . Then, when the solenoid 84 is demagnetized and the plunger 85 and the first interlocking member 86 are moved forward in the direction indicated by the arrow c, the second contact portion 97 becomes the contacted portion 95 as shown in FIG. The second interlocking member 88 rotates around the pivot 87 in the direction indicated by the arrow d, and the opening / closing member 48 is moved to the closed state X through the states shown in FIGS. And move forward.

  While the opening / closing member 48 advances to the closed state X side, the contacted portion 95 slides relatively upward on the second contact portion 97 as shown in FIGS. To do. In the state shown in FIG. 12C, the contact guide portion 93a of the engagement portion 93 contacts the engaged portion 92 in tandem with the separation of the contacted portion 95 from the second contact portion 97. In contact with each other, the second interlocking member 88 rotates in the direction of the arrow d as the first interlocking member 86 advances. Thereafter, as shown in FIGS. 12E and 12F, the engaged portion 92 is disengaged upward from the contact guide portion 93a, and the engaging portion 93 is engaged with the engaged portion 92 from below. Thereby, in the closed state X of the opening / closing member 48, the opening / closing member 48 can be locked by the locking means 51 via the second interlocking member 88.

  The game ball dropped onto the opening / closing member 48 in the closed state X rolls on the inclined upper surface portion 72 in the direction indicated by the arrow e, and then passes through the inclined portions 63 and 64 from the left end of the inclined upper surface portion 72. Fall down.

  When the first open / close winning means 17 completes the opening / closing operation for a predetermined number of rounds, the jackpot state is finished. However, if the jackpot lottery that triggered the jackpot state is accompanied by a probability change to the high probability state, the state shifts to a high probability state (specific game state) after the jackpot state ends. During this high probability state, the jackpot lottery probability is high, while the opening time of the second special symbol starting means 16 becomes long, and the special symbols of the first special symbol display means 21 and the second special symbol display means 22 are increased. When the fluctuation time is shortened, the state becomes short. For this reason, the player continues to make a right hit to concentrate the game ball in an advantageous right hit passage 25.

  When the game ball wins the normal winning means 19, the normal symbol of the normal symbol display means 20 fluctuates for a predetermined time, and the changed normal symbol stops in a winning manner or a losing manner according to the winning lottery result. If the normal symbol stops in the hit state, the second special symbol starter 16 is released for a longer time than in the normal probability state.

  On the other hand, at this time, the first open / close winning means 17 has the open / close member 48 in the closed state X. After that, it falls to the second special symbol starting means 16 side. For this reason, if the 2nd special symbol starting means 16 will be in an open state, the possibility that the game ball from the right strike path 25 will win the 2nd special symbol starting means 16 becomes high.

  If a game ball wins the second special symbol starting means 16, the second special symbol of the second special symbol display means 22 and the effect symbols 37a to 37c of the effect symbol display means 37 fluctuate synchronously and fluctuate for a predetermined time. Later, it will stop according to the lottery result. And if the 2nd special symbol after a change stops in a big hit mode, a big hit state will generate | occur | produce and the 1st opening-and-closing type winning means 17 will open and close for a predetermined number of rounds with a predetermined opening and closing pattern. The high probability state ends under a predetermined condition such that the special symbol fluctuates a predetermined number of times, and thereafter returns to the normal probability state.

  In this embodiment, when the opening / closing member 48 is locked by the locking means 51 in the closed state X and the driving means 49 converts the opening / closing member 48 from the closed state X to the open state Y, the driving means 49 is interlocked with the driving means 49. Since the lock by the locking means 51 is released before the opening / closing member 48 is driven in the opening direction, the opening / closing member 48 of the first opening / closing type winning means 17 is illegally opened by hitting the glass door 4. It is possible to prevent fraudulent acts such as Further, the opening / closing member 48 is not unexpectedly retracted due to an impact or the like when the game ball falls on the opening / closing member 48 in the closed state X.

  Further, since the locking means 51 is provided in the interlocking means 50 for interlocking the driving means 49 and the opening / closing member 48, compared with the case where the locking means 51 is provided between the interlocking means 50 and the fixed side of the winning case 46 or the like. The structure can be simplified. Further, the interlocking means 50 includes a first interlocking member 86 on the drive means 49 side and a second interlocking member 88 on the opening / closing member 48 side, and the locking means 51 includes an engaged portion 92 provided on the second interlocking member 88; An engaging portion 93 that is provided on the first interlocking member 86 and is detachably engaged with the engaged portion 92 when the opening / closing member 48 is in the closed state X; In the case of converting to the open state Y, since the second interlocking member 88 is interlocked after the lock means 51 is detached, the opening / closing member 48 can be reliably locked with a simple structure.

  Further, a second interlocking member 88 having an engaged portion 92 is pivotally supported by a pivot 87 so that the first interlocking member 86 provided so as to be movable in a direction substantially orthogonal to the pivot 87 is connected to the engaged portion 92. Since the engaging portion 93 is provided to engage with and disengage from a substantially orthogonal direction, the engaging portion 93 of the lock means 51 is utilized by utilizing the difference in movement between the first interlocking member 86 and the second interlocking member 88. The engaged portion 92 can be easily and reliably engaged / disengaged.

  Furthermore, the contact part 95 provided in the 2nd interlocking member 88, the 1st contact part 96 provided in the 1st interlocking member 86, and the 2nd contact part 97 are provided, and the 1st contact part 96 is provided. After the locking means 51 is released, the opening / closing member 48 is brought into contact with the contacted portion 95 so as to convert it from the closed state X to the open state Y, and the second contact portion 97 converts the opening / closing member 48 from the closed state X to the open state Y. After that, since the locking means 51 is allowed to be released from the abutted portion 95, both the interlocking members 86 and 88 can be reliably interlocked.

  13 and 14 illustrate a second embodiment of the present invention. In this embodiment, when the solenoid 84 is demagnetized to return the opening / closing member 48 to the closed state X, after the opening / closing member 48 returns to the closed state X, the second interlocking member 88 rotates around the pivot 87. The engaging portion 93 of the locking means 51 is engaged with the lower side of the engaged portion 92.

  That is, in this embodiment, as shown in FIG. 13, when the first interlocking member 86 moves halfway in the direction indicated by the arrow c due to the demagnetization of the solenoid 84, the second interlocking member 88 rotates around the pivot 87 to the end. As a result, the opening / closing member 48 is positioned in the closed state X, and the second contact portion 97 is detached from the contacted portion 95 upward. Then, after that, the first interlocking member 86 further moves in the direction of the arrow c, so that the engaging portion 93 is engaged below the engaged portion 92 as shown in FIG. The opening / closing member 48 is locked in the closed state X.

  In this way, the stroke of the solenoid 84 becomes somewhat longer, but the configuration of the linkage means 52 can be simplified.

  FIG. 15 illustrates a third embodiment of the present invention. In this embodiment, the second interlocking member 88 of the interlocking means 50 is configured in a bell crank shape (substantially L-shaped), and is connected to a solenoid 84 constituting the driving means 49 and a plunger 85 thereof. An interlocking member 86 is arranged to be movable in the vertical direction. The second interlocking member 88 has two arm portions 88a and 88b across the pivot 87, and one arm portion 88a is connected to the opening / closing member 48 and the other arm portion 88b is connected to the first interlocking member 86. ing. And between the arm part 88b and the 1st interlocking member 86, the locking means 51 and the cooperation means 52 are provided similarly to 1st Embodiment.

  When the second interlocking member 88 having the two arm portions 88a and 88b is used in this way, the solenoid 84, the plunger 85, and the first interlocking member 86 constituting the driving means 49 may be arranged in the vertical direction. . Thus, if the solenoid 84, the plunger 85, and the first interlocking member 86 are arranged in the vertical direction, the dimension in the front-rear direction of the first open / close-type winning means 17 despite the fact that the opening / closing member 48 slides in the front-rear direction. Can be reduced.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to this each embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the opening / closing member 48 is used as the conversion member, and the opening / closing type winning means 17 that opens and closes by sliding the opening / closing member 48 in the front-rear direction is illustrated, but the same applies to game components other than the winning means. It can be implemented.

  For example, when a blocking member is disposed on the upper side of the passageway so that it can be moved back and forth, and when the blocking member protrudes on the passageway, the passage of the game ball to the passageway is prevented, and the backward movement from the passageway to the rear In addition, in the case of a game component that allows the game ball to pass through the passage, the blocking member can be used as a conversion member in the same manner as in each embodiment. Therefore, the game component provided with the conversion member is not limited to the open / close type winning means 17 provided with the open / close member 48.

  In the embodiment, the open state Y of the opening / closing member 48 is the first state advantageous to the player, and the closed state X is the second state disadvantageous to the player, but the first state is compared to the second state. It may be a state that is relatively advantageous to the player, and need not be the open state Y with respect to the second state of the closed state X, and both the first state and the second state may be open. The conversion operation direction of the conversion member may be appropriately determined according to the operation mode of the game component.

  The driving means 49 is a solenoid 84 having a plunger 85, and the first interlocking member 86 connected to the plunger 85 is linearly moved by the solenoid 84. The first interlocking member 86 is fixed to the shaft, and the locking means 51 and the interlocking means 52 are provided between the first interlocking member 86 and the rear side (second interlocking member 88) of the opening / closing member 48 of the first embodiment, for example. It may be provided. In addition, when the first interlocking member 86 is linearly moved as in the first embodiment, a pinion gear is provided on the rotating shaft of the motor constituting the driving means 49, and the pinion gear is located on the first interlocking member 86 side. You may make it mesh with a rack gear.

  The locking means 51 locks the conversion member in the second state, and when the drive means 49 converts the conversion member from the second state to the first state, the lock means 51 is interlocked with the drive means 49 before the conversion member is driven. The lock means 51 is provided at a fixed location such as the winning case 46, and the lock means 51 is electrically connected to the drive means 49 when the drive means 49 drives the conversion member. The lock may be released in conjunction with it.

  The interlocking device 50 is structurally simple if it is constituted by two members, ie, the first interlocking member 86 on the drive member 49 side and the second interlocking member 88 on the conversion member side, but the first interlocking member 86 and the second interlocking member are the same. In addition to a member having two members with member 88, a member having three members or more members may be used. Also in the case of two members, the second interlocking member 88 may be integrated with the conversion member, for example, using a part of the conversion member as described above.

  When the lock means 51 and the linkage means 52 are incorporated in the linkage means 50, it is desirable that the first linkage member 86 and the second linkage member 88 move in different directions as illustrated in the respective embodiments. By changing the movement direction, the structure of the lock means 51 and the linkage means 52 can be simplified.

  Furthermore, it goes without saying that the present invention can be similarly applied to an arrangement ball machine and other various ball game machines in addition to pachinko machines.
