A bottom plate 63 is disposed between the pair of guide rails 62 on the front side of the guide passage 39, that is, on the front side of the opening / closing drive means 47 disposed on the rear upper side of the guide passage 39. The front side of the guide passage 39 is formed in a bowl shape by the pair of guide rails 62.

  An opening 65 that opens downward is provided between the pair of guide rails 62 at a portion corresponding to the rear side of the guide passage 39, that is, the lower side of the opening / closing drive means 47. Then, on the rear side of the guide passage 39, the game balls are guided by the opposing ball guide portions 64b of the both guide rails 62 with the lower portion of the game balls protruding downward from the ball guide portions 64b. It has become. The opening 65 includes the rear end of the guide rail 62 and is provided on the rear side of the guide passage 39.

A bending guide passage 48 is provided on the upper side of the holding case 66. The bending guide passage 48 may be provided on the rear case 35 side.

  The plunger 68 of the solenoid 67 protrudes to the front side, and opens and closes the opening / closing member 46 via the operation tool 69 at the front end. The plunger 68 is urged in the protruding direction by a spring 70. The operation tool 69 is disposed in the support case 59 above the guide passage 39 and is pivotally supported by a support shaft 71 in the left-right direction at an intermediate portion in the vertical direction.

  The operating tool 69 has a pair of left and right operating portions 72 that sandwich the engaging protrusions 58 of the respective opening and closing members 46 from both the upper and lower sides in front of the support shaft 71, and is rotated around the support shaft 71 by the forward and backward movement of the plunger 68. Thus, the opening / closing member 46 is rotated around the pivot 57. The opening / closing member 46 normally stands up around the pivot 57 by a spring 70 and closes the winning openings 36 and 37. The operation unit 72 is disposed on both the left and right sides of the guide passage 39.

  The bent guide passage 48 is for guiding the game ball from the guide passage 38 by bending it toward the drop passage 51 on the one side along the game board 7, and is covered with a passage cover 50. The lateral guide passage 52 is for guiding and dropping the game ball from the drop passage 51 to one side in the left-right direction of the big winning means 16. The rear side of the drop passage 51 and the lateral guide passage 52 is closed by a rear wall 74. The winning detection switch 42 is removably inserted into a holding portion 75 formed in the rear case 35 in the middle of the drop passage 51 and is locked by a locking claw 76.

  The back guide passage 41 is connected to the guide passage 39 and is formed obliquely backward and downward so that the game ball from the guide passage 39 is guided onto the guide rod 29 of the big winning means 16 and dropped. . The winning detection switch 43 is removably inserted into a holding portion 77 formed in the rear case 35 in the middle of the back guide passage 41 and is locked by a locking claw 78. Since the back guide passage 41 is inclined rearward and downward, the winning detection switch 43 is disposed in a diagonal direction so as to cross the back guide passage 41 downward. The rear case 35 and the winning case 26 of the big winning means 16 are arranged close to each other in the vertical direction.

  A mounting hole 49 for the special symbol starting means 15 is formed in the game board 7 so as to penetrate in the front-rear direction corresponding to the shape of the front main body 34 side including the guide passages 38, 39, the support case 59 and the like. The mounting hole 49 is disposed on the peripheral wall 61 formed at a substantially right angle in the front-rear direction with respect to the game area 12 of the game board 7 and the lower peripheral wall 61 on the lower side of the guide rail 62 so as to correspond to the opening 65. And a recess 79 formed to be recessed.

  The peripheral wall 61 is perforated from the front side (game area 12 side) across the front and rear surfaces of the game board 7. The recess 79 is formed in a circular arc shape in a rear view from the back side of the game board 7 in the thickness direction of the game board 7, for example, the rear side of the game board 7. It is stepped. For this reason, the attachment hole 49 has a shape in which the lower side of the guide rail 62 is recessed downward. A rotary tool such as a router is used for drilling the mounting hole 49 including the peripheral wall 61 and the recess 79.

  In the pachinko machine having the above configuration, when a game ball falling from the upper part of the game area 12 passes through the normal symbol starting means 17, the normal symbol of the normal symbol display means 22 blinks and fluctuates for a predetermined time. When the changed normal symbol stops at the winning symbol, the opening / closing driving means 47 of the special symbol starting means 15 is operated, and the pair of left and right opening / closing members 46 swings upward and the winning opening 37 is opened. The That is, the opening / closing member 46 is normally held closed by the spring 70. Therefore, when the solenoid 67 of the opening / closing drive means 47 is excited, the plunger 68 moves backward against the spring 70 and the operating tool 69 rotates around the support shaft 71 in the clockwise direction as shown in FIG. 72. The opening / closing member 46 tilts around the pivot 57 in the opening direction via the engagement protrusion 58, and the winning opening 37 is opened.

  The special symbol starting means 15 has a normally open winning opening 36 and an openable winning opening 37 at the top and bottom, and if a game ball wins any of the winning openings 36, 37, the corresponding winning detection switch 42 is provided. , 43 detect the game ball.

  For example, when a game ball wins in the always-open type winning opening 36, the game ball is guided to the back side of the game board 7 through the guide passage 38. Then, the game ball is guided in the bending guide passage 48 in the lateral direction along the game board 7 and falls downward in the fall passage 51 and passes through the winning detection switch 42 during the fall. Is done.

  Thereafter, the game ball is guided laterally along the back side of the game board 7 by the lateral guide passage 52 near the upper side of the big winning means 16, and then falls downward near the side of the winning case 26 of the big winning means 16. To do. For this reason, the game ball won in the winning opening 36 does not fall on the big winning means 16 on the back side of the game board 7.

  Further, when the opening / closing member 46 is in the open state on the openable winning opening 37 side, the game ball falling on the opening / closing member 46 wins the winning opening 37. Then, the game ball is guided to the guide passage 39 side through the pair of guide plates 55, guided to the back side of the game board 7 by the guide passage 39, and then passed through the back guide passage 41 to the big winning means 16. Falls on the guide rod 29 on the winning case 26 and falls from the rear end of the guide passage 39 to the rear side of the big winning means 16. The game ball is detected by passing the winning detection switch 43 in the middle of the back guide passages 40 and 41.

  When either of the winning detection switches 42 and 43 detects the winning of the game ball, a big win is made on the main control board (not shown), and a lottery out of play is performed, and an effect control board (not shown) is controlled according to the lottery result. As a result, the special symbol on the special symbol display means 23 fluctuates for a predetermined time and stops at either the jackpot symbol or the off symbol. In addition, by the control of the effect control board, the effect symbol 19 of the image display means 13 fluctuates for a predetermined time in synchronization with the change of the special symbol of the special symbol display means 23, and the effect symbol 19 corresponding to the jackpot symbol and the off symbol Stop. Then, when the lottery result is a big win, the game shifts to a special game advantageous to the player, for example, the open / close plate 27 of the big winning means 16 is opened and closed a predetermined number of times after the special symbol stops at the big win symbol.

  When the game ball won in the lower prize opening 37 is guided to the back side of the game board 7 by the guide passage 39, the bottom plate 63 and the pair of guide rails 62 are in a bowl shape on the front side of the guide passage 39. Therefore, the game ball rolls on the bottom plate 63 as shown by b1 in FIGS. 5 and 7, and is guided by the bottom plate 63 and one of the left and right guide rails 62.

  However, since the gap between the pair of guide rails 62 is an open portion 65 on the rear side that passes below the opening / closing drive means 47, the ball guide portions 64b of the pair of guide rails 62 allow the flow shown in FIGS. As shown in b2, the game ball is guided in a state in which a part thereof protrudes downward from the ball guide portion 64b of the guide rail 62. For this reason, although the inclination angles of the left and right guide rails 62 are the same, the game ball after passing through the bottom plate 63 is lowered downward compared to the case of rolling on the bottom plate 63 until then. The guide path 39 is guided along the locus b as shown in FIG.

  Therefore, on the rear side of the guide passage 39, the height of the game ball passing over the guide passage 39 becomes lower than the inclination angle of the guide passage 39, so the vertical dimension of the special symbol starting means 15 is reduced accordingly. can do.

  In particular, when the opening / closing driving means 47 is disposed above the guide passage 39, the game ball is guided by the left and right guide rails 62 below the opening / closing driving means 47, thereby passing the lower side of the opening / closing driving means 47. Since the height of the game ball is lowered, the opening / closing drive means 47 can be placed close to the guide passage 39 while ensuring a space for passing the game ball below the opening / closing drive means 47, and the overall vertical dimension of the game ball is reduced. Can be reduced.

  In addition, the rear side for guiding the game ball by the ball guide portion 64b of the guide rail 62 has an open portion 65 between the left and right guide rails 62, so that the vertical direction of the rear side of the guide passage 39 is higher than that of the bowl-shaped case. The dimensions of can be reduced.

  For this reason, when the front main body portion 34 including the guide passage 39 is molded from a synthetic resin material, for example, when the entire lower surface of the guide passage 39 is made substantially the same height in consideration of extraction from the mold, the guide passage The amount of protrusion to the lower side of 39 can be minimized.

  Further, back guide passages 40 and 41 connected to the respective guide passages 38 and 39 and winning detection switches 42 and 43 are separated from the front main body portion 34 and provided on the rear case 35 side, and the rear case 35 is provided on the back side of the game board 7. Since the winning detection switches 42, 43, etc. are on the front main body 34 side, the vertical dimension can be reduced.

  Thus, when the guide rails 62 are provided on the rear side of the guide passage 39 on the left and right sides through the opening portion 65, the guide passage 39 can be attached if it is disposed close to the lower peripheral wall 61 on the lower side of the attachment hole 49. There is a possibility that burrs generated on the rear edge side when the hole 49 is drilled may interfere with the game ball.

  However, since the recess 79 is provided in the peripheral wall 61 of the mounting hole 49 corresponding to the rear side of the guide rail 62, the game ball is drawn by the guide passage 38 regardless of burrs during processing of the mounting hole 49 of the game board 7. It can guide smoothly. Moreover, since the recess 79 is formed in a stepped shape from the back side of the game board 7, the opening on the front end side of the mounting hole 49 does not increase downward, and the front decoration plate 45 allows the mounting hole 49 to be The opening can be reliably covered.

  10-13 illustrate a second embodiment of the present invention. The guide passage 39 of this embodiment has a pair of left and right guide rails 62, and each guide rail 62 is formed with a notch 81 on the opposite inner side on the rear side corresponding to the opening / closing drive means 47. Therefore, the interval between the ball guide portions 64a of the guide rail 62 on the front side of the notch portion 81 and the interval between the ball guide portions 64b on the notch portion 81 side are set to the front side as shown in FIGS. The rear side is larger than that.

  Also in this embodiment, there is a bottom plate 63 that connects a pair of guide rails 62 on the lower side of the guide passages 38 and 39, but the bottom plate 63 is not in contact with the game ball. . An opening 65 is provided between the guide rails 62 on the rear side of the guide passage 39 so as to correspond to the notches 81.

  In this embodiment, the pair of guide rails 62 guides the game balls through the ball guide portions 64 a and 64 b over substantially the entire length of the guide passage 39. However, since the space between the ball guide portions 64b of the left and right guide rails 62 is wide on the rear side corresponding to the opening / closing drive means 47, the game ball passing below the opening / closing drive means 47 is the first As in the embodiment, it passes through a low position.

  FIG. 14 illustrates a third embodiment of the present invention. In FIG. 14, a guide rail 62 is provided over the entire length of the guide passages 38 and 39, and the game balls are guided by the opposing ball guide portions 64b. 14A has the both ball guide portions 64b substantially parallel to each other, and FIG. 14B has the both ball guide portions 64b spread outward.

  Thus, even when the guide rail 62 is provided over the entire length of the guide passage 39, the concave portion 79 formed on the peripheral wall 61 side of the mounting hole 49 of the game board 7 is formed on the rear side of the guide passage 39, and in particular the hole of the mounting hole 49. What is necessary is just to provide in the rear-end part side which a burr | flash tends to generate | occur | produce at the time of a process.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to this each Example, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the section where the opening 65 is provided between the left and right guide rails 62 and the game ball is guided by the ball guide 64b, the opening / closing drive means 47 and the game ball arranged on the rear side and the upper side of the guide passage 39 are provided.
