The start winning opening 14 is constituted by a member protruding from the front surface of the game board 11, and has a so-called pocket structure provided with an opening through which one game ball can pass on the upper surface of the member. When a game ball wins at the start winning opening 14, for example, four game balls are paid out to the upper plate 27A for each win, and a special symbol determination is made. The determination result is displayed on the display screen 34.

  Specifically, as shown in FIG. 1, normally, three special symbols 13A, 13B, and 13C are displayed on the display screen 34 side by side. Each of these special symbols 13A, 13B, and 13C is composed of, for example, a plurality of types of symbols that represent numbers “0” to “11”. Normally, a predetermined type of symbol is stopped and displayed for each special symbol 13A, 13B, 13C. Then, when a game ball is won at the start winning opening 14, these special symbols 13A, 13B, 13C are scrolled up and down, and the special symbols 13A, 13B, 13C are, for example, left, right after a predetermined time elapses. , Stop display in the middle order. When the special symbol success / failure determination result is a win (hereinafter referred to as “big hit”), as shown in FIG. 1, all the three special symbols 13A, 13B, and 13C are stopped and displayed with the same symbol (Zero eyes), and thereafter , The game shifts to “big hit game”. On the other hand, if the result of determining whether or not the special symbol is correct is not displayed, a combination other than a double eye is displayed and the normal gaming state continues.

  The special winning opening 15 has a horizontally long rectangular shape and is closed by a movable door 15T in a normal gaming state. And when it becomes a "hit game", as shown in FIG. 1, the movable door 15T is brought down to the front side over a predetermined period. Then, the grand prize opening 15 is opened forward, and a large number of game balls can enter the big prize opening 15 with the movable door 15T as a guide. When a game ball enters the big prize opening 15, for example, 15 game balls are paid out to the upper plate 27A for each entry.

  Here, when a period from when the movable door 15T is opened until it is closed is referred to as “round”, in one round, the opening time of the movable door 15T has reached 30 seconds, or a game ball is placed in the big prize opening 15. The process ends when any end condition of 10 balls has been satisfied. Further, the “big hit game” is continued up to 15 rounds, for example.

  When game balls enter the general winning ports 20 and 20 and the side winning ports 21 and 21 provided below the game board 11, a predetermined number of winning balls are paid out to the upper plate 27A for each winning. It is.

  Then, all the game balls that have not won any of the above winning ports 14, 15, 20, 20, 21, 21, 21 are taken into the out port 16 arranged at the lower end of the gaming area R1.

  A start gate 18 is provided at the center in the vertical direction of the left portion of the display frame 23. The start gate 18 has a portal structure through which game balls can pass. When a game ball passes through the start gate 18, a normal symbol success / failure determination is performed.

  The stage 23S is provided with, for example, three distribution holes (not shown), and one of the distribution holes is discharged from the warp outlet 23Y through the internal passage of the display frame 23. Here, since the warp outlet 23Y is located immediately above the start winning opening 14, most of the game balls released from the warp outlet 23Y win the starting winning opening 14.

  An upper step surface 23K is formed at the upper left corner of the display frame 23, and the right side of the upper step surface 23K is higher than the left side. A game ball that is driven into the game area R1 flows into the game area R1 on the right side over the upper step surface 23K depending on the shooting speed of the game ball, and collides with the upper step surface 23K to enter the game area R1 on the left side. It can be divided into what flows down.

  On the left side portion of the display frame body 23, a side flow basket 37 is provided, and a ball entrance 37A to the side flow basket 37 is opened in the upper step surface 23K. Further, a side movable door 37T is provided at the entrance 37A. The side movable door 37T is normally closed. When the game ball passes through the start gate 18 described above and the result of the normal symbol success / failure determination is “small hit”, the side movable door 37T is, for example, Defeated sideways by 1.5 seconds for 3 times. When the game ball enters the side flow basket 37, the game ball flows down the vertical path portion 37V and is guided to the horizontal path portion 37H.

  As shown in FIG. 3, the side downflow rod 37 has a vertical path portion 37V whose upper end portion extends substantially vertically, a horizontal path portion 37H bent at a right angle from the lower end portion of the vertical path portion 37V, and a horizontal path portion 37H. A first downflow path 51 and a second downflow path 52 extending downward from the path portion 37H are provided. The first and second flow down paths 51 and 52 are arranged side by side, extend straight from the horizontal path portion 37H vertically downward, and are bent from the middle.

  The first downflow path 51 is arranged on the vertical path portion 37V side from the second downflow path 52, and the upper end opening of the first downflow path 51 is a side start winning opening 51N. Further, the side start winning opening 51N is disposed on the game area entry hole 12E side from the upper step surface 23K. A detection switch 37S is provided at the upper end of the first flow-down path 51 in order to detect a game ball that has passed through the side start winning opening 51N.

  More specifically, the first downflow path 51 is a state in which the upper end straight portion 51A extending linearly with a uniform width downward from the side start winning opening 51N and the width of the upper end straight portion 51A are widened to the left side. An intermediate wide portion 51B extending downward, an intermediate bent portion 51C extending from the lower end portion of the intermediate wide portion 51B diagonally downward to the right, and a lower end straight portion 51D extending vertically downward from the intermediate bent portion 51C. It has. Of the inner wall on the left side of the first flow path 51, the back surface in the range from the horizontal path portion 37 </ b> H to the upper end of the intermediate bent portion 51 </ b> C forms the right inner wall of the second flow path 52. Further, the left inner wall in the second flow down path 52 extends straight in the vertical direction.

  In the present embodiment, the side downfall 37 corresponds to the “game medium passage” of the present invention, the horizontal path portion 37H of the side downfall 37 corresponds to the “lateral downflow passage” of the present invention, and The first flow path 51 corresponds to the “downward flow path” of the present invention. The detection switch 37S corresponds to the “detection unit” of the present invention.

  When a game ball enters the first flow path 51 of the first and second flow paths 51, 52, that is, after entering the horizontal path portion 37H, the game ball enters the side start winning opening 51N. In such a case, the game ball is detected by the detection switch 37S and, as in the case where the game ball is entered into the start winning opening 14, a predetermined prize ball is paid out and a special symbol determination is performed, and the determination result is special. It is displayed on the display screen 34 using symbols 13A, 13B, and 13C (see FIG. 1). If the determination result is a win, the “big hit game” for opening the side movable door 38T described above is executed, and a large profit is given to the player. That is, each time a ball entering the side start winning hole 51N is detected by the detection switch 37S, the player is given a chance to obtain a larger profit than usual, such as a jackpot, together with a certain profit of a certain number of prize balls. On the other hand, when a game ball enters the second downstream path 52 of the first and second downstream paths 51, 52, that is, after entering the horizontal path portion 37H, the game ball enters the side start winning opening 51N. If the player does not enter the game, the player is not given a chance to win a certain number of prize balls. It should be noted that regardless of which of the first and second flow paths 51 and 52 the game ball enters, the game ball does not flow down the game area R1 again and is taken into the back side of the game board 11. In addition, the “privilege” of the present invention includes the “small hit” based on the above-described normal symbol success / failure determination result, the “big hit” based on the special symbol success / failure determination result resulting from the passage of the detection switch 37S, and the game ball payout (prize ball). It is not limited to this, and so-called “probability game”, “short-time game”, and the like may be used.

  As described above, the pachinko gaming machine 10 according to the present embodiment can obtain a profit larger than usual by winning the side start winning opening 51N in the same manner as winning the starting winning opening 14. Since the side start winning opening 51N is arranged closer to the game area entry hole 12E than the start winning opening 14, it is likely to be a target of fraud using a so-called “thread ball”. The thread ball is, for example, a hole formed in a regular game ball to form an illegal ball W (corresponding to the “illegal game medium” of the present invention), and is fixed to the hole through an operation line L (for example, a piano line). It has a structure. In the pachinko gaming machine 10 according to the present embodiment, the return regulating protrusion 50 according to the present invention is provided in the side flow rod 37 in order to suppress an act of illegally entering the side start winning opening 51N using this yarn ball. It has been.

  As shown in FIG. 3, the return regulating protrusion 50 is disposed in the middle of the middle wide portion 51B of the first flow down path 51 in the vertical direction, and straight out vertically from the side start winning opening 51N in the middle wide portion 51B. It extends in a cantilever shape from the extended inner surface on the right side. Specifically, the intermediate wide portion 51B protrudes from the right inner surface to the left side in the horizontal direction and is gradually curved downward toward the tip. In contrast, the inner surface on the left side of the first flow path 51 bulges to the side (left side) where the lower part of the upper side of the return regulating protrusion 50 is away from the return regulating protrusion 50. As a result, an intermediate wide portion 51B is formed in the first flow path 51, and the space between the left inner surface and the return regulating protrusion 50 in the first flow path 51B is substantially the same width as the upper end straight section 51A. Yes. That is, the width from the upper end of the intermediate wide portion 51B to the middle position is substantially the same as that of the upper end straight portion 51A, and the lower portion of the middle wide portion 51B is wider than the upper end straight portion 51A. 3, the inner surface on the right side of the first flow path 51 corresponds to the “first inner surface portion” of the present invention, and the inner surface on the left side corresponds to the “second inner surface portion” of the present invention.

  As shown in FIG. 5, the protruding amount of the return restricting protrusion 50 from the inner surface of the intermediate wide portion 51 </ b> B is about 1.5 times the diameter of the game ball, and is below the return restricting protrusion 50. One game ball can be accommodated. Further, the return regulating protrusion 50 is gradually reduced in thickness from the proximal end toward the distal end. Furthermore, the front end surface 50S of the return regulating protrusion 50 is parallel to the vertical direction, and a portion where the lower surface 50T of the return regulating protrusion 50 and the front end surface 50S intersect is pointed at an acute angle and directed downward. Yes.

  As shown in FIG. 4, the return regulating protrusion 50 is formed with a receiving groove 60. The receiving groove 60 is provided from the distal end portion to the proximal end side of the return restriction projecting piece 50, and includes an operation line introducing portion 60A, a retaining restriction portion 60B, and a groove end portion 60C.

  The operation line introducing portion 60 </ b> A is provided over a range of about one third from the distal end portion of the return regulating projection piece 50 to the distal end portion in the long side direction of the return regulating projection piece 50, and the distal end of the return regulating projection piece 50. The width gradually decreases from the left and right corners of the portion toward the center in the width direction of the return regulating protrusion 50. The inner side surface of the operation line introducing portion 60A is an inclined surface 61 that is inclined so as to protrude toward the center side in the width direction of the operation line introducing portion 60A from the upper surface 50J to the lower surface 50T of the return regulating protrusion 50. Yes. As a result, the area of the lower surface 50T of the return restricting protrusion 50 is increased, and the range of covering the illegal sphere W can be increased, and the illegal sphere W is moved to the detection switch 37S above the return restricting protrusion 50. Can be difficult or impossible to do.

  The removal restricting portion 60B has a uniform width of 1 to 2 [mm], for example, and extends from the back of the operation line introducing portion 60A to a position near the base end of the return restricting protrusion 50.

  The groove end portion 60C is a circular hole having an inner diameter larger than the width of the retaining prevention portion 60B, and a part thereof communicates with the retaining restriction portion 60B. Further, as shown in FIG. 5, an annular recess 62A that is recessed in a stepped shape is formed at the opening edge on the upper surface side of the groove end portion 60C, and the metal ring 62K is fixed in a state in which the annular recess 62A is fitted. ing. As shown in FIG. 4, the metal ring 62K has a shape in which a part of the circular ring is cut out so as to correspond to the retaining restriction portion 60B. As shown in FIG. 5, the inner edge portion of the metal ring 62K is tapered and thin, and the portion protruding from the inner surface of the groove end portion 60C is the cutting portion 62 according to the present invention.

  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 is operated, the game ball on the upper plate 27A (see FIG. 1) is driven obliquely upward into the game area R1 from the game area entry hole 12E, and flows down the right or left side of the display frame 23. Then, when the side movable door 37T is tilted sideways due to the entrance to the starting gate 18 and the entrance 37A is opened, the game balls that have been driven into the game area R1 flow down from the entrance 37A to the side. 37 can enter the game balls, and when some of the game balls enter the side start winning opening 51N, it is detected by the detection switch 37S and the special symbol determination is made, When the determination result is a win, a “big hit game” that opens the side movable door 38T is executed, and a large profit is given to the player.

  However, just because the ball enters the side start winning opening 51N, the special symbol success / failure determination is not necessarily a win, so the yarn ball will enter the side start winning opening 51N until the special symbol success / failure determination becomes a hit. It can be a target of fraud that causes frequent spheres. Specifically, an illegal ball W is placed in the upper plate 27A (see FIG. 1) and fired into the side flow basket 37 of the game area R1 in the same manner as a normal game ball, and the side start of the side flow basket 37 is started. If it passes the detection switch 37S of the winning opening 51N, it can become a target of fraud that causes the illegal ball W to be raised above the side start winning opening 51N by the operation line L and pass again to the detection switch 37S.

  However, the pachinko gaming machine 10 according to the present embodiment is provided with the return restricting protrusion 50 at the position that has passed the detection switch 37S of the side start winning opening 51N, so that it is possible to suppress the above-described fraud. More specifically, in order to prevent the illegal sphere W from reaching the side flow down rod 37 from the upper plate 27A, the illegal sphere W is formed with the operation line L sufficiently long in order to prevent the illegal sphere W from being stalled by the operation line L. Launched from the launcher.

  Then, as shown in FIG. 6A, the operation line L is curved so as to follow the illegal sphere W without being pulled, and the illegal sphere W enters the side flow rod 37. At this time, since the operation line L is sufficiently long, when the illegal ball W enters the side start winning opening 51N of the side flow basket 37, it passes through the detection switch 37S and is located at the back of the first flow path 51. Reach up to. A return regulating protrusion 50 is provided at the back of the first flow path 51, and the return regulating protrusion 50 is located vertically below the side start winning opening 51N. For example, it comes into contact with the upper surface 50 </ b> J of the return regulation protrusion 50, is guided to the left side of the return regulation protrusion 50, and passes through the return restriction protrusion 50. Then, when the illegal sphere W is positioned below the return restricting protrusion 50, the limit of the length of the operation line L is reached as shown in FIG. Tension is applied.

  Here, since the side start winning opening 51N is arranged on the game area entry hole 12E side with respect to the upper step surface 23K where the ball entrance 37A is formed, the operation line L is a return restriction of the side start winning opening 51N. The improper sphere W is pushed toward the inner surface on the right side of the first flow path 51 by being pressed against the inner surface on the right side where the projecting piece 50 is disposed. Then, the operation line L is received in the receiving groove 60 of the return regulating protrusion 50.

  At this time, when the operation line L is not positioned at the center in the width direction of the return restriction projecting piece 50, the operation line L is guided to the operation line introducing portion 60 </ b> A of the receiving groove 60 and Move toward the center in the width direction. Here, since the inner side surface of the operation line introducing portion 60A is an inclined surface 61 and the lower edge portion of the operation line introducing portion 60A is sharpened at an acute angle, the operation line L is the lower edge of the operation line introducing portion 60A. As compared with the case where the inner surface of the operation line introducing portion 60A is a vertical surface and the operation line L is in line contact with the inner surface of the operation line introducing portion 60A, the operation is smoothly performed. The line L is guided to the back side of the operation line introducing portion 60A. Then, the operation line L passes through the retaining restriction portion 60B and fits in the groove end portion 60C.

  As a result, as shown in FIG. 6C, when the illegal sphere W is pulled up by the operation line L, the illegal sphere W comes into contact with the lower surface 50T of the return regulating protrusion 50 and can be pulled up further. Disappear. That is, it is possible to suppress an illegal act of raising the illegal ball W to the upper side of the side start winning opening 51N through the operation line L and passing it again to the detection switch 37S. Here, an unauthorized person who knows that the illegal ball W has been caught on the return restricting protrusion 50 loosens the operation line L and performs a pendulum operation below the return restricting protrusion 50 to receive the operation line L in the receiving groove 60. Even if it is going to be removed from the groove, the outlet-side retaining restricting portion 60B is narrower than the groove terminating portion 60C in which the operation line L is accommodated, so that the operation line L returns to the retaining restricting portion 60B side by the inner surface of the groove terminating portion 60C. And the pendulum movement of the illegal ball W is also prevented. In addition, since the cutting portion 62 protrudes from the inner surface of the groove terminal portion 60C, the operation line L can be cut depending on the material of the operation line L.

  Thus, according to the pachinko gaming machine 10 of the present embodiment, the illegal ball W with the operation line L enters the first flow path 51, and then the operation line L is pulled back from the outside of the pachinko gaming machine 10. Is performed, the operation line L is bent at the right bent portion of the horizontal path portion 37H and the first flow path 51, and the illegal sphere W is suspended below the bent portion. Then, the operation line L is brought closer to the return regulating protrusion 50 provided on the bent portion side, and the illegal ball W is placed on the lower surface 50T of the return regulating protrusion 50 in a state where the operation line L is received in the receiving groove 60. Since it cannot abut and cannot be pulled upward, fraudulent acts by the illegal sphere W with the operation line L can be suppressed.
