[Invention of Claim 1]
In the first aspect of the invention, in order to move the opening / closing member from the closed position to the open position, the rotating member is normally rotated by moving the moving member from the start end position to the end position by the drive source. At this time, the rotation restricting portion retreats from the rotation range of the rotation contact portion of the rotation lever, the rotation of the rotation lever is allowed, and the opening / closing member moves from the closed position to the open position. On the other hand, when the turning lever receives a force from the opening / closing member due to an unauthorized opening operation on the opening / closing member, the turning contact portion interferes with the turning restricting portion to restrict the turning of the turning lever. The movement from the closed position to the open position is restricted. At this time, the rotation restricting portion receives an improper pressing force that is inclined with respect to the retraction direction of the rotation restricting portion and faces the retreat position side from the rotation contact portion. Here, when the improper pressing force is small, the direct acting component that is the component in the retraction direction of the rotation restricting portion of the improper pressing force is smaller than the resistance force, and the direct acting component force is larger than the resistance force. Sometimes, the rotation restricting portion moves to the retracted position side. Then, when the rotation restricting portion retreats from the rotation range of the rotation contact portion, the rotation restriction of the rotation lever is released. As described above, in the gaming machine of the present invention, when the load due to the unauthorized opening operation becomes larger than a predetermined value while the rotation of the rotation lever is restricted, the rotation restriction of the rotation lever is released. Since the load due to the unauthorized opening operation is released, damage to the opening / closing member and its peripheral members due to the unauthorized opening operation can be suppressed.

Further, in the present invention, when the moving member moves from the start end position to the end position in response to the power from the drive source, the interlocking protrusion of the moving member contacts the interlocking contact portion of the rotation lever so that the rotation lever Can be rotated. Further, when the moving member is at the start end position, the interlocking protrusion and the interlocking contact part , or the rotation restricting part and the rotation contact part are arranged at intervals, so that the interlocking protrusion and the interlocking contact part Before the pivot contact portion of the pivot lever that is driven to rotate by contact with the pivot control portion at the standby position reaches the pivot regulation portion, the pivot regulation portion moves to the retracted position side and rotates. Interference with the contact portion can be avoided.

In addition, if the rotation restricting portion is configured to be close to the rotation contact portion when the moving member is at the start position, the rotation lever almost rotates when an unauthorized opening operation is performed. The rotation is restricted by the rotation restricting portion. As a result, unauthorized opening can be restricted with the opening / closing member held in the substantially closed position.

The moving member can be linearly moved in a direction orthogonal to the rotation axis of the rotation lever, and the contact flat surface is parallel to the linear movement direction, so that the contact flat surface rotates. The rotation position of the rotation lever does not change from when it interferes with the contact portion until it retracts from the rotation range of the rotation contact portion. Thereby, in the initial stage in which the unauthorized opening operation is performed, unauthorized opening can be restricted without changing the position of the opening and closing member.

[Invention of claim 4 ]
According to the fourth aspect of the present invention, the rotation lever can be smoothly rotated when the rotation contact portion reaches the end of the contact flat surface on the start end position side.

[Invention of claim 5 ]
According to the configuration of the fifth aspect of the invention, since the improper pressure can be dispersed in the direction of the rotation axis of the rotation lever, the durability can be improved.

[Invention of claim 6 ]
According to the sixth aspect of the present invention, when the rotation restricting portion receives an improper pressure from the rotation contact portion, the rotation restricting portion is shifted in a direction orthogonal to the retraction direction and the rotation restricting portion is rotated. It is suppressed that the moving lever moves out of the rotation range.

[Invention of Claim 7 ]

The position of the flange tip mounting member 54 shown in FIG. 6 corresponds to the “starting position” of the present invention, and the position of the flange tip mounting member 54 shown in FIG. 8 corresponds to the “terminal position” of the present invention.

  The solenoid 51 is excited when the game ball passes through the start gate 18 (see FIG. 1) and the lottery result is “small hit”. That is, in the gaming machine 10 according to the present embodiment, the second start winning opening 14B is normally controlled by the movable wing pieces 14C and 14C, and the movable wing pieces 14C and 14C are turned into the “small hit” when the ball is restricted. Open for a predetermined period (eg, 0.4 seconds). When the movable wing pieces 14C and 14C are opened, more game balls enter the second start winning opening 14B than usual, and more jackpot games are judged, and a large number of prize balls are received. Increases the probability of acquisition. For this reason, an unauthorized opening operation is attempted to pry open the movable blade pieces 14C and 14C using a wire or the like even though the state is not “small hit”, that is, the solenoid 51 is in a non-excited state. May be.

  Here, in the gaming machine 10 according to the present embodiment, when the unauthorized opening operation is performed, the rotation restriction that restricts the unauthorized opening of the movable wing pieces 14C and 14C by restricting the rotation of the rotation lever 60. The protrusion 57 is provided integrally with the plunger tip mounting member 54. Specifically, as shown in FIG. 10A, the rotation restricting protrusion 57 protrudes outward from each side wall 54B of the plunger tip mounting member 54, and the rotation axis J2 (see FIG. 4 (see FIG. 10A) (only one rotation restricting protrusion 57 is shown in FIG. 10A).

  The rotation restricting protrusion 57 is disposed at a position near the lower end of the rear end portion of the plunger tip mounting member 54 and has a substantially square cross-sectional shape. As shown in FIG. 12, the upper end of the rotation restricting projection 57 is a flat contact surface parallel to both the rotation axis J <b> 2 of the rotation lever 60 and the linear movement direction of the plunger 52, that is, the front-rear direction. 57H (corresponding to the “rotation restricting portion” of the present invention) is formed. Specifically, the contact flat surface 57 </ b> H is formed from the rear end to the front end position of the rotation restricting protrusion 57. The upper surface of the front end portion of the rotation restricting protrusion 57 is an arcuate surface 57A that curves downward as it goes forward, and the rear end of the arcuate surface 57A continues to the contact flat surface 57H. Yes.

  As shown in FIG. 11, the rotation restricting protrusion 57 is received in the rotation restricting recess 70 of the turning lever 60 in a state where the solenoid 51 is not excited. The rotation restricting recess 70 is formed at the side edge of the second lever protrusion 61B facing rearward, and is open rearward.

  As shown in FIG. 11, the rotation restricting concave portion 70 is formed between an upper concave portion constituting wall 71 and a lower concave portion constituting wall 72 which face each other in the vertical direction in a state where the solenoid 51 is not excited. The lower recess-constituting wall 72 has an upper surface parallel to the horizontal plane and is separated from the rotation restricting protrusion 57.

  As shown in FIG. 12, the upper recessed portion constituting wall 71 is located below the rear interlocking protruding piece 68, and the surface facing the rotation restricting recessed portion 70 is inclined so that the rear side is slightly directed downward with respect to the horizontal plane. The lower inclined surface 73 is a rear inclined surface 74 whose rearward surface is inclined so that the upper side is slightly rearward with respect to the vertical surface. And the intersection line of the downward inclined surface 73 and the back inclined surface 74 is the ridgeline part 70S (equivalent to the "rotation contact part" of this invention) which concerns on this invention.

  As shown in FIG. 11, the inclination of the rear inclined surface 74 is steeper than the straight line connecting the rotation axis J2 and the ridge line portion 70 when viewed from the direction of the rotation axis J2 of the rotation lever 60. Thus, as the distance from the ridge line portion 70S increases, the line moves away from the straight line counterclockwise in FIG.

  The ridge line portion 70S is disposed close to the rotation restricting protrusion 57 in a state where the solenoid 51 is not excited, and a part of the contact flat surface 57H of the rotation restricting protrusion 57 is within the rotation range of the ridge line portion 70S ( It is arrange | positioned on the left side of the dashed-dotted line of FIG. In this state, when an unauthorized opening operation is performed on the movable blade piece 14 </ b> C, the ridge line portion 70 </ b> S of the rotation lever 60 interferes with the contact flat surface 57 </ b> H of the rotation restriction projection 57, and The rotation is restricted. In the present embodiment, an example in which the ridge line portion 70S is in contact with the contact flat surface 57H of the rotation restricting protrusion 57 is shown.

  On the other hand, when the solenoid 51 is excited from the state shown in FIG. 11, the flange tip mounting member 54 moves backward on the support wall 45 integrally with the plunger 52, as shown in the change in FIG. 11 to FIG. 13. The interlocking protrusion 56 contacts the interlocking contact surface 66T. At this time, the rotation restricting protrusion 57 also moves backward from the position shown in FIG. 11 while slidingly contacting the ridge line portion 70S of the rotation lever 60, and the contact flat surface 57T rotates around the ridge line portion 70S of the rotation lever 60. It is arranged behind the moving range (on the right side of the dashed line in FIG. 13). When the flange tip mounting member 54 moves to the end position, the ridge line portion 70S of the turning lever 60 interferes with the contact flat surface 57H of the turning restricting projection 57 as shown in the change in FIGS. Instead, the rotation lever 60 rotates about the rotation axis J2 such that the rearward inclined surface 74 of the rotation lever 60 slides on the arc surface 57A of the rotation restricting protrusion 57. That is, when power is transmitted from the drive source 50, the movable blade pieces 14C and 14C move from the closed position to the open position without the rotation lever 60 being restricted.

  Now, as shown in FIG. 12, in the state where the unauthorized opening operation is performed and the rotation of the rotation lever 60 is restricted, the contact flat surface 57H of the rotation restricting protrusion 57 is obliquely rearward from the ridge line portion 70S. Receives an improper pressure F facing downward. At this time, the rotation restricting protrusion 57 is applied with a linear component force f1 which is a component in the linear movement direction of the flange tip mounting member 54 of the improper pressure F, that is, a component in the front-rear direction. Further, the rotation restricting protrusion 57 receives the frictional force f3 based on the vertical component force f2 that is the vertical component of the improper pressure F in the forward direction that is opposite to the direction of the linear component force f1. Further, an urging force by the compression coil spring 53 is applied in the same forward direction as the frictional force f3. The combined force of the frictional force f3 and the urging force of the compression coil spring 53 corresponds to the “resistance force” in the present invention. When the improper pressure F is small with the flange tip mounting member 54 in the starting position, the combined force of the frictional force f3 and the urging force of the compression coil spring 53 is greater than the direct acting component force f1. The ridgeline portion 70S and the contact flat surface 57H of the rotation restricting protrusion 57 are configured not to slide.

  Then, if the improper pressure F becomes greater than or equal to a predetermined value in a state where the rotation lever 60 is restricted from rotating, the direct acting component force f1 is greater than the force that combines the frictional force f3 and the biasing force of the compression coil spring 53. The flange tip mounting member 54 moves rearward against the biasing force of the compression coil spring 53 due to the linear component force f1, and the contact flat surface 57H of the rotation restricting projection 57 is rotated by the ridgeline portion 70S. Retreat outside the moving range (on the right side of the dashed line in FIG. 11). Then, the rotation lever 60 is released from the rotation restriction and rotates about the rotation axis J2, and the movable blade pieces 14C and 14C move from the closed position to the open position. The positional relationship between the flange tip mounting member 54 and the rotation lever 60 when the contact flat surface 57H is retracted from the rotation region of the ridge line portion 70S is the same as that when the solenoid 51 is excited, as shown in FIG. The positional relationship is as shown.

  Further, while the rotation lever 60 is restricted, the vertical component force f2 of the improper pressure F is applied downward to the rotation restricting protrusion 57. As described above, the flange tip mounting member 54 is The downward movement is restricted by the support wall 45 (see FIG. 11) provided on the base member 41. Accordingly, it is possible to prevent the flange tip mounting member 54 from being displaced downward and the contact flat surface 57H of the rotation restricting protrusion 57 from being out of the rotation range of the ridge line portion 70S.

  The position of the contact flat surface 57H of the rotation restricting projection 57 when the flange tip mounting member 54 is at the start position corresponds to the “standby position” of the present invention (see FIGS. 6 and 11). The position of the contact flat surface 57H when the flange tip mounting member 54 is at the end position corresponds to the “retracted position” of the present invention (see FIGS. 8 and 14).

  The description regarding the configuration of the pachinko gaming machine 10 according to the present embodiment has been described above. Next, the effect of the pachinko gaming machine 10 of this embodiment will be described. When the operation knob 28 (see FIG. 1) is operated and a game ball is driven into the game area R1, and a part of the game ball that has flowed down randomly enters the first start winning opening 14A or the second start winning opening 14B, A jackpot game is determined. When the result of the determination is a big hit and a gaze is displayed on the liquid crystal screen 30G, the open / close door 15T is rotated to open the special winning opening 15 over a predetermined period, which is larger than usual. The prize ball is paid out to the upper plate 26.

  The second start winning opening 14B is normally restricted from entering by the movable wing pieces 14C, 14C. When the game ball passes through the start gate 18 and the lottery result is “small hit”, the solenoid 51 is excited and the plunger 52 moves rearward. Then, the flange tip mounting member 54 moves linearly from the start position to the end position, the interlocking protrusion 56 of the flange tip mounting member 54 comes into contact with the interlocking facing surface 66T of the rotation lever 60, and the rotation lever 60 is rotated. It is rotated around the moving axis J2. Then, the movable wing pieces 14C, 14C move from the closed position to the open position in conjunction with the turning lever 60, and the game ball can enter the second start winning opening 14B while guiding the movable wing pieces 14C, 14C. It becomes.

  On the other hand, when an unauthorized opening operation is performed in which the movable blade pieces 14C and 14C are to be opened with a wire or the like in a state where the solenoid 51 is not excited, the ridge line portion 70S of the rotating lever 60 is moved to the flange tip mounting member 54. Interference with the rotation restricting projection 57 (specifically, the contact flat surface 57H) restricts the rotation of the rotation lever 60. Here, when the flange tip mounting member 54 is at the start end position, the contact flat surface 57H is close to the ridge line portion 70S, so that when the unauthorized opening operation is performed, the turning lever 60 is almost turned. Without being rotated, the rotation is restricted by the rotation restricting projection 57. This makes it possible to restrict unauthorized opening while the movable blade piece 14C is held in the substantially closed position.

  Here, if the unauthorized opening operation continues to be performed while the rotation lever 60 is restricted in rotation, the contact flat surface 57H of the rotation restriction protrusion 57 is obliquely downward from the ridge line portion 70S of the rotation lever 60. The improper pressure F facing the direction is received (see FIG. 12). Then, the rotation restricting protrusion 57 moves rearward by the linear motion component force f1 which is a component in the front-rear direction of the improper pressure F. Here, since the contact flat surface 57H that contacts the ridge portion 70S is parallel to the linear movement direction (that is, the front-rear direction) of the flange tip mounting member 54, the rotation restricting protrusion 57 moves to the end position side. The rotation position of the rotation lever 60 does not change until the ridge line portion 70S reaches the end portion of the contact flat surface 57H on the start end position side (see FIG. 13). As a result, at the initial stage when the unauthorized opening operation is performed, unauthorized opening can be restricted without changing the position of the movable blade piece 14C. Further, since the contact flat surface 57H is parallel to the rotation axis of the rotation lever 60, variation in the improper pressure F in the direction of the rotation axis J2 is suppressed, and the movement of the rotation restricting projection 57 is prevented. Stabilization is achieved.

  When the rotation restricting protrusion 57 moves to the end position side and the ridge line portion 70S reaches the front end of the contact flat surface 57H, the contact flat surface 57H deviates from the rotation range of the ridge line portion 70S, and the contact flat surface. The interference between 57H and the ridge portion 70S is eliminated, and the rotation lever 60 rotates about the rotation axis J2 (see FIG. 14). Here, since the circular arc surface 57A that is continuous with the contact flat surface 57H is curved downward as it goes forward, the rotation lever 60 can be smoothly rotated.

  As described above, in the gaming machine 10 according to the present embodiment, when the rotation of the rotation lever 60 is restricted and the load due to the unauthorized opening operation becomes a predetermined magnitude or more, the rotation of the rotation lever 60 is rotated. Since the restriction is released and the load due to the unauthorized opening operation is released, damage to the movable blade 14C and its peripheral members due to the unauthorized opening operation can be suppressed. In addition, since the two sets of the contact flat surface 57H and the ridge line portion 70S are provided, the load due to the unauthorized opening operation is dispersed and the durability is improved.

  Further, since the contact area between the ridge line portion 70S and the contact flat surface 57H when the rotation restricting projection 57 moves linearly by the direct acting component force f2, the rotation restricting protrusion 57 is linearly moved stably. It becomes possible to make it. Furthermore, since the improper pressure F can be dispersed in the direction of the rotation axis of the rotation lever 60, durability can be improved.

[Second Embodiment]
The second embodiment of the present invention is different from the first embodiment in the positional relationship between the interlocking protrusion 56V and the interlocking facing surface 66T, and the positional relationship between the contact flat surface 57H and the ridge line portion 70S. Specifically, as shown in FIG. 15, when the solenoid 51 is de-energized, the arc surface 56A of the interlocking protrusion 56V comes into contact with the interlocking facing surface 66T of the rear interlocking protrusion 68, and the contact flat surface 57H. And a ridge line portion 70S.

  When the solenoid 51 is excited, as shown in FIGS. 15 to 17, the flange tip mounting member 54V moves from the start position to the end position, and the turning lever 60 is pushed by the interlocking protrusion 56V and turns. . At this time, since the rotation restricting protrusion 57V also moves directly toward the end position, the ridge line portion 70S of the turn lever 60 contacts the rotation restricting protrusion 57V when the flange tip mounting member 54V is at the start end position. When the position of the flat surface 57H (the position of the flat contact surface 57H shown in FIG. 15) is reached, the flat contact surface 57H retracts rearward and does not interfere with the ridge line portion 70S. Then, when the flange tip mounting member 54V moves to the end position, the ridge line portion 70S of the rotation lever 60 does not interfere with the contact flat surface 57H of the rotation restricting projection 57, and the rotation lever 60 moves the rotation axis J2. Rotate around the center.

  On the other hand, when an unauthorized opening operation is performed, as shown in the change in FIGS. 15 to 16, the rotation lever 60 is slightly rotated about the rotation axis J2, and then the ridge line portion 70S is applied. The rotation of the rotation lever 60 is restricted by interference with the contact flat surface 57H. Then, when the unauthorized opening operation is further performed, the rotation restricting protrusion 57V moves to the end position side (the right side in FIG. 16), and the ridge line portion 70S and the contact flat surface 57H, as in the first embodiment. Interference is eliminated. According to this embodiment, the same effect as that of the first embodiment can be obtained.

[Other Embodiments]
The present invention is not limited to the above-described embodiment. For example, the embodiments described below are also included in the technical scope of the present invention, and various modifications are possible within the scope of the invention other than the following. It can be changed and implemented.

  (1) In the above embodiment, the contact flat surface 57 of the rotation restricting projection 57 and the rotation lever 60 are in line contact when an unauthorized opening operation is performed. There may be a point contact structure.

  (2) In the above embodiment, an example in which the present invention is applied to a mechanism that opens and closes the movable wing piece 14C that restricts the entry of a game ball into the second start winning opening 14B has been described. You may apply to the mechanism which opens and closes 15 movable doors 15T.

( 3 ) Like the rotating lever 60 </ b> W shown in FIG. 18, the upper recess-constituting wall 71 </ b> W has a lower surface that is parallel to the horizontal surface when the solenoid 51 is de-energized, The configuration may be such that the ridge portion 75S of the shaped protrusion 75 interferes with the flat contact surface 57H.

( 4 ) In the above embodiment, at the position where the ridge line portion 70S is in contact with the contact flat surface 57H of the rotation restricting protrusion 57, the opposite of the direct acting component force f1 that is the backward component of the improper pressure F. The “resistance force” of the present invention is configured by the total force of the frictional force f3, which is the forward component of the direction, and the biasing force of the compression coil spring 53. The “resistance force” of the present invention may be configured only by the friction force f3 by adjusting the friction coefficient of the material.

( 5 ) In the above embodiment, the “standby position” of the present invention is the position of the contact flat surface 57H when the flange tip mounting member 54V is the start end position. It may be the position of the flat contact surface 57H.

( 6 ) In the above embodiment, the direction in which the contact flat surface 57H of the rotation restricting projection 57 retreats outward (rearward) from the rotation range of the ridge portion 70S of the rotation lever 60 is from the drive source 50 to the flange. In both cases where the power is transmitted to the tip mounting member 54 (when controlled based on the game determination result) and when the power is not transmitted (when an unauthorized opening operation is performed), the plunger 52 Although configured to be parallel to the linear movement direction, the vertical component force f2 of the improper pressure F is applied from the ridge line portion 70S to the abutting flat surface 57H during the improper opening operation, and thus is supported by the support wall 45. However, it is not necessary to limit the retracting direction of the contact flat surface 57H to be parallel to the linear movement direction of the plunger 52. In other words, when the unauthorized opening operation is performed and the direct acting component force f1 of the unauthorized pressing force F becomes larger than the “resistance force” of the present invention, the contact flat surface 57H rotates the rotating lever 60. What is necessary is just to comprise so that it may move to the terminal position side so that it may evacuate from the range.
