Pressed. When the solenoid 66 is excited, as shown in FIG. 12, the plunger 67 is drawn into the solenoid 66 and the compression coil spring 68 is compressed and deformed. When the excitation of the solenoid 66 is stopped, the compression is performed as shown in FIG. The plunger 67 moves forward by the elastic force of the coil spring 68.

  As shown in FIG. 2, in order to assemble the linear drive source 65 to the mechanism case 54, a plunger insertion hole (not shown) is formed in the upper end portion of the rear end surface of the mechanism case 54 so as to penetrate therethrough. The plunger 67 is inserted, and the front end surface of the yoke 66 </ b> A is assigned to the rear end surface of the mechanism case 54. Further, on the rear end surface of the mechanism case 54, a pair of rear end protrusions 55T (only one rear end protrusion 55T is shown in FIG. 2) so as to sandwich the yoke 66A in the left-right direction. ) Is protruding. Then, the screw insertion hole 55N penetrated and locked to the rear end protrusions 55T and 55T and the female screw hole 66N (see FIG. 10) formed in the U-shaped iron plate 66B of the yoke 66A are aligned with each other. It has been stopped.

  As shown in FIG. 10B, the plunger connecting member 70 is provided with an opposing ring 71 that is fitted to the plunger 67 and faces the front end flange 67F, and one end of the compression coil spring 68 contacts. A through-hole 71A (see FIG. 9A) is formed at the center of the opposing ring 71, and a pair of abutting protrusions 72 from the two positions 180 degrees away from the opposing ring 71 toward the tip flange 67F. 73 protrudes. The side surfaces 72S and 73S of the abutting projections 72 and 73 are vertical surfaces parallel to the vertical direction, as shown in FIGS. 9A and 9B.

  The plunger connecting member 70 is assembled in a state where the plunger 67 is inserted into the through hole 71A of the opposing ring 71 and the front end surfaces of the abutting protrusions 72 and 73 are in surface contact with the front end flange 67F. Thereby, the connection recessed part 80 with which the opposing ring 71 and the front-end | tip flange 67F opposed is formed in the front-end | tip part of the plunger 67 left-right symmetrically. Further, the portion of the front end flange 67F that faces the counter ring 71 in the connecting recess 80 is a sliding contact allowing portion 81. Further, a portion of the opposing ring 71 that faces the front end flange 67F (see FIG. 10A) between the abutting projections 72 and 73 has a lower abutting projection 73 side with a stepped flange. A stopper protrusion 74 is formed so as to protrude toward the 67F side, and a portion above the stopper protrusion 74 of the opposing ring 71 is a depressed portion 75 (corresponding to the “illegal prohibition engaging portion” according to the present invention). . A stepped surface 75B of the depressed portion 75 and the stopper projection 74 is located above and laterally from the abutting projection 73, as shown in FIG. 9A.

  The distal end portion of the plunger 67 and the plunger connecting member 70 constitute a linear motion output portion 65S of the linear motion drive source 65. The pair of coupling protrusions 60, 60 are received in the pair of coupling recesses 80, 80, so that the linear motion output portion 65S of the linear motion drive source 65 is coupled to the rotation levers 56, 56. Has been. Here, the front end surfaces of the connecting protrusions 60 and 60 are located outside the side surfaces 72S and 73S of the abutting protrusions 72 and 73, and the connecting protrusion 60 and the abutting protrusions 72 and 73 interfere in the vertical direction. It is supposed not to. Further, the interval between the stopper projection 74 and the tip flange 67F is wide enough to allow the coupling projections 60, 60 to pass therethrough. Thereby, for example, the plunger connecting member 70 is inserted from above between the connecting protrusions 60, 60, and the turning levers 56, 56 can be connected to the direct acting output portion 65 </ b> S of the direct acting drive source 65. . In general, the connecting protrusion 60 is located above the stopper protrusion 74 of the depressed portion 75.

  When the solenoid 66 is excited and the plunger 67 is pulled into the solenoid 66 due to the connection between the linear output part 65S of the linear drive source 65 and the rotation levers 56, 56, the state shown in FIGS. As shown in the change, the second arm portion 56B of the turning lever 56 is pulled rearward and turned around the turning shaft 58, and accordingly, the first arm portion 56A moves upward to connect the lever. The protrusion 53 is pushed up. As a result, the pair of movable blade pieces 14C and 14C are opened to the left and right as shown in FIG.

  Specifically, when the pair of movable blade pieces 14C and 14C are disposed at the closed position, the connecting protrusion 60 is positioned above the step surface 75B of the depressed portion 75 of the connecting recess 80 as shown in FIG. Is arranged. In this state, when the second arm portion 56 </ b> B of the rotation lever 56 is pulled rearward by the plunger 67, the slidable contact allowing portion 81 constituted by the front end flange 67 </ b> F is connected to the front side of the connecting projection 60. Press the arc surface. At this time, the connecting protrusion 60 moves rearward and also moves downward as the second arm portion 56B rotates, and comes into sliding contact with the sliding contact allowing portion 81. Here, since the sliding contact allowance portion 81 is constituted by the front end flange 67F and has a smooth flat surface, the connecting protrusion 60 smoothly slides and moves along the sliding contact allowance portion 81. As a result, FIG. As shown in FIG. 6, the second arm portion 56B rotates rearward, and the pair of movable blade pieces 14C and 14C open to the left and right as shown in FIG.

  When the excitation of the solenoid 66 is stopped and the plunger 67 moves forward as shown in the change from FIG. 6 to FIG. 5 by the elastic force of the compression coil spring 68, the second arm portion 56B of the rotation lever 56 rotates. The first arm portion 56 </ b> A moves downward with the moving shaft 58 as a center and pushes down the lever connecting projection 53. As a result, the pair of movable blade pieces 14C and 14C are closed and brought into an upright state as shown in FIG.

  Specifically, as shown in FIG. 11, when the pair of movable blade pieces 14C and 14C are arranged at the open position, the connection projection 60 contacts the sliding contact allowance portion 81 and is in the connection recess 80. It is arranged on the lower end side. In this state, when the second arm portion 56B of the rotation lever 56 is pushed forward by the elastic force of the compression coil spring 68, the sliding contact allowing portion 81 is separated from the connecting projection 60, and the movable blade piece 14C and the rotation are rotated. Due to the dead weight of the lever 56, the second arm portion 56B rotates forward, and the pair of movable blade pieces 14C, 14C close as shown in FIG.

  When the movable blade pieces 14C and 14C are arranged at the closed position, for example, when the upper end portions of the movable blade pieces 14C and 14C are illegally pulled by a tool or the like to move to the open position, the connecting protrusion 60 11 moves backward in the connecting recess 80, and the second flat surface 63 of the connecting protrusion 60 contacts the bottom surface 75 </ b> A of the depressed portion 75 in the connecting recess 80 as shown in FIG. 11. In this state, even if the second arm portion 56B receives rotational force by the unauthorized opening operation of the movable wing piece 14C, the first flat surface 61 of the connecting projection 60 contacts the step surface 75B of the depressed portion 75. The inside of the connecting recess 80 cannot move obliquely downward, the rotation of the rotation lever 56 is restricted, and the movable blade pieces 14C and 14C are held in the closed position. Furthermore, when trying to open the movable wing piece 14C, the corner 62 of the connecting projection 60 bites into the corner between the bottom surface 75A and the stepped surface 75B of the depression 75, and as the force for opening the movable wing piece 14C increases, Engagement between the connecting protrusion 60 and the depressed portion 75 is deepened. Thereby, unauthorized opening of the movable blade piece 14C can be reliably prohibited.

  In the present embodiment, the movable wing pieces 14C and 14C are normally arranged in a closed position (in a standing state), and the number symbols stopped and displayed on the normal symbol display unit 17 are odd numbers. Further, the direct drive source 65 is controlled so that the movable blade pieces 14C and 14C are opened over a predetermined period (for example, 0.4 seconds).

Then, if the determination result is a big hit and a glance is displayed on the liquid crystal display unit 24G, the movable door 15T is rotated to open the special winning opening 15 over a predetermined period. A large amount of prize balls are paid out to the upper plate 26.

  Here, the first start winning opening 14A is arranged at a place where it is difficult for a game ball to enter, and the second starting winning opening 14B is normally restricted by the movable wing pieces 14C and 14C. However, when the game ball passes through the start gate 18 and a predetermined number symbol is stopped and displayed on the normal symbol display unit 17 as a result of the lottery, the linear drive source 65 is energized to move the movable wing pieces 14C and 14C. Open over 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 using the movable wing pieces 14C and 14C as a guide, and more jackpot games are judged. The probability that a large amount of prize balls will be obtained increases. For this reason, there is a case in which an illegal act of illegally opening the movable wing pieces 14C and 14C by causing a wire or the like to enter the inside of the front frame 39 may be performed.

  However, in the start winning unit 40 (see FIG. 2) provided in the pachinko gaming machine 10 of the present embodiment, when the linear drive source 65 is driven, as described above, the linear drive source 65 and the movable wing piece 14C. , 14C and the sliding contact allowing portion 81 of the connecting concave portion 80 are smoothly slidably contacted, and the linear motion output portion 65S of the linear motion drive source 65 and the movable blade pieces 14C, 14C are The movable wing pieces 14C and 14C move from the closed position to the open position in conjunction with each other. However, when the movable wing pieces 14C and 14C are opened illegally, the connection protrusion 60 is formed in the depression 75 in the connection recess 80. Abutting against the stepped surface 75B, the connecting projection 60 cannot slide in contact with the inner surface of the connecting recess 80, and the direct acting output portion 65S of the direct acting drive source 65 and the movable blade pieces 14C, 14C are not interlocked. Pieces 14C, 14C held in closed position That. Thereby, acquisition of an illegal prize ball can be prevented.

  Further, in the start winning unit 40, each rotary lever 56 is a separate component from the movable blade pieces 14C, 14C, and the first arm portion 56A that protrudes forward from the rotary shaft 58 and is connected to the movable blade piece 14C. And the second arm portion 56B protruding upward from the rotating shaft 58 and connected to the plunger 67, the degree of freedom of arrangement of the linear drive source 65 with respect to the movable blade piece 14C is high. Become. In other words, the length of the first and second arm portions 56A and 56B can be set as appropriate, and the linear drive source 65 can be arranged at any position in the front-rear direction and the up-down direction with respect to the movable blade piece 14C. Further, the degree of freedom of the arrangement of the linear drive source 65 with respect to the movable blade piece 14C is increased.

  Further, in the pachinko gaming machine 10 according to the present embodiment, the connecting protrusion 60 and the connecting recess 80 for converting the plunger 67 into the rotation of the rotation lever 56 are arranged symmetrically with the plunger 67 interposed therebetween. As compared with the case where only one set of the connecting protrusion 60 and the connecting recess 80 is provided, the load is dispersed and deformation is prevented. In addition, the mechanism case 54 that surrounds the rotation lever 56 and the linear motion output portion 65S of the linear motion drive source 65 prevents unauthorized operation of the rotation lever 56 and the linear motion output portion 65S.
