JP-A-9-173563

  By the way, according to the pachinko ball rectifying passage described above, each game ball is merely guided along the passage direction by each of the two rows of ball passages. In this case, if there are many game balls guided by each of the two rows of ball passages, these game balls generate a ball clog in each of the two rows of ball passages and smoothly reach the ball approaching passage. There is a risk of not.

  In view of the above, the present invention includes a ball passage device and a ball passage device that are devised so that the game ball can be smoothly moved to the rectifying passage portion without causing clogging. The purpose is to provide a game machine.

In solving the above-mentioned problems, the ball passage device according to the present invention is as described in claim 1.
It is formed in a longitudinal hollow shape from the upper side to the lower side so that the game ball can pass therethrough.

In the ball passage device,
A main guide passage part (Ac) for receiving a game ball falling from above through the space part (Ab);
Along with the branch wall portion (92e) in parallel to the main guide passage portion, the excess game balls are directed downward from the main guide passage portion due to an excess of received game balls in the main guide passage portion. A sub-guide passage (Ad) for receiving the guide,
Extending downward from the main guide passage portion and the sub guide passage portion along the branch wall portion so that the width gradually becomes narrower toward the branch wall portion than the main guide passage portion and the sub guide passage portion. Both rectifying passage portions (Ae, Af) formed in
The main guide passage part is
The two pairs of opposing wall portions (92c, 92d, 92f, 92e) fall from above to at least one of the opposing wall portions (92c, 92d) facing in the width direction of the branch wall portion. Providing a protrusion that changes the falling direction of the game ball,
The sub-guide passage is
The two pairs of opposing wall portions (92c, 92d, 92q, 92e) fall from above onto at least one of the opposing wall portions (92c, 92d) facing in the width direction of the branch wall portion. Providing a protrusion that changes the falling direction of the game ball,
Each of the protrusions is inclined downward at a predetermined inclination angle so as to be separated from the branch wall portion in directions opposite to each other.

  According to such a configuration, the game ball falling through the space from above is received by the main guide passage portion. At this time, the game ball is received by the main guide passage portion without being branched to the sub guide passage portion side.

  Here, in the main guide passage portion, as described above, the projecting portion changes downward at a predetermined inclination angle so as to change the falling direction of the game ball falling from above and away from the branch wall portion. It is provided so that it may incline toward.

  Therefore, the game ball received in the main guide passage portion as described above is guided downward while moving in the inclination direction of the projection portion while falling down along the projection portion in the main guide passage portion. Is done. This is because, even if there are many game balls received in the main guide passage portion, the game balls are not formed in the main guide passage portion based on the above-mentioned predetermined inclination angle in the main guide passage portion due to the shape of the protruding portion. It means that it is guided smoothly.

  When the number of game balls received by the main guide passage portion increases, each game ball enters the sub guide passage portion.

  Here, the projecting portion of the sub guide passage portion has a predetermined shape so as to change the falling direction of the game ball falling from above and away from the branch wall portion in the direction opposite to the projecting portion of the main guide passage portion. It is provided so as to be inclined downward at an inclination angle.

  Accordingly, the game ball entering the sub guide passage portion as described above is guided downward while falling in the sub guide passage portion along the protrusion and moving in the inclination direction of the protrusion. This means that even if there are many game balls that enter the auxiliary guide passage part, the game balls will not be clogged due to the shape of the protruding part of the auxiliary guide passage part based on the predetermined inclination angle. It means that the guide is smoothly guided in the guide passage.

  According to the above, even if a large number of game balls stay in the ball passage device in a full state, the game balls staying below the ball passage device can, for example, pull out the game balls in the tray. If it moves downward, the game ball staying in the ball passage device may cause clogging in the protruding direction or the inclined direction of the protruding portion inside the main guide passage portion or the sub guide passage portion. Instead, it moves smoothly and is guided downward, and is sent separately to each rectifying passage portion extending from the main guide passage portion and the sub guide passage portion.

  Here, as described above, each of the rectifying passage portions extends downward along the branch wall portion so as to become narrower sequentially toward the branch wall portion side than the main guide passage portion and the sub guide passage portion.

  Therefore, each rectification passage part can rectify | smooth well each game ball sent smoothly from a main guide passage part and a sub guide passage part, without clogging, and can send it below.

  Here, in the main guide passage portion and the sub guide passage portion, the movement of the game ball is disturbed by sending the game ball downward while changing the falling direction of the game ball in relation to the shape of each protrusion. The resulting ball clogging can be satisfactorily rectified by each rectifying passage portion and sent downward without incurring inside the rectifying passage portion under the above-described configuration of each rectifying passage portion.

  As described above, the ball passage device is provided in the ball passage device under the synergistic action of the guide action of the main guide passage portion and the sub guide passage portion and the rectification action of the both rectification passage portions as described above. The staying game ball can be smoothly sent downward.

According to a second aspect of the present invention, in the ball passage device according to the first aspect,
Each of the protrusions is set to a value that is greater than twice and less than three times the outer diameter of the game ball in the length in the inclination direction.

  According to this, the game balls moving in an inclined manner in the main guide passage portion and the sub guide passage portion move smoothly without receiving a ball pressure from each other in combination with the predetermined inclination angle. can do. As a result, the function and effect described in claim 1 can be further improved.

According to a third aspect of the present invention, in the ball passage device according to the first or second aspect,
The main guide passage part is formed so as to receive a game ball falling from above through the space part in the vicinity of the upper end part (t) of the branch wall part.

  According to this, since the main guide passage portion is formed so as to receive the game ball falling from above in the vicinity of the upper end portion of the branch wall portion, the guide portion of the projection portion of the game ball is guided in the inclination direction. As a result, the operational effects of the invention of claim 1 or 2 can be further improved.

Moreover, according to the description of claim 4, the pachinko gaming machine according to the present invention is
A gaming machine body (Ba) formed by assembling the game board (10) to the body frame (BF);
A front door (FD) supported to be openable and closable by the gaming machine body;

  The introduction portion Aa is an upper curved wall portion 92b (hereinafter also referred to as a front upper curved wall portion 92b; see FIGS. 12 and 16A) of the front side wall portion 92c, and both upper curved wall portions 92b ( Hereinafter, it is also referred to as a rear upper curved wall portion 92b (see FIGS. 13 and 16B), and includes an upper wall portion of the left side wall portion 92q and an upper wall portion of the right side wall portion 92f.

  Here, the front upper curved wall portion 92b of the front side wall portion 92c has a substantially semi-elliptical cross section that protrudes forward so as to be inclined downward at a predetermined guide inclination angle from the left side to the right side (FIG. 16A). Reference). On the other hand, the rear upper curved walls 92b of the rear curved wall 92d are substantially rearwardly convex in a cross section of four minutes so as to incline at the predetermined guiding inclination angle in the same direction as the front upper curved wall 92b. One elliptical shape (see FIG. 16B) is formed. Note that the predetermined guide inclination angle described above is such that each game ball introduced from the inlet portion 92a into the introduction portion Aa has a lower opening in the introduction portion Aa without causing clogging in the introduction portion Aa. The angle is set so as to be smoothly guided toward the portion (described later).

  Thus, the introduction part Aa smoothly moves the game balls entering from the upper inlet part 92a to the right under the predetermined guide inclination angle, and drops them into the space part Ab from the lower opening part. As shown in FIG. 14, the lower opening of the introduction portion Aa is located between the left boundary portion of the rear upper curved walls 92b of the introduction portion Aa and the corresponding portion of the front upper curved wall portion 92b. Is formed so as to open into the space Ab on the right side of the left boundary portion.

  The space Ab is formed in the ball guide passage 92 between the introduction portion Aa, the main guide passage portion Ac, and the sub guide passage portion Ad. The space Ab is a front upper curved wall in the front side wall portion 92c. The flat wall portion formed below the portion 92b, the flat wall portion formed below the rear upper curved wall portion 92b in the rear side wall portion 92d, and the left and right side wall portions 92q and 92f with respect to these both flat wall portions The corresponding wall portion is formed in a rectangular hollow shape in the longitudinal section. Accordingly, the space Ab opens at the upper end opening thereof into the introduction portion Aa through the lower opening, and the lower opening of the space Ab includes the main guide passage portion Ac and the lower opening. It opens in the sub guide passage part Ad through each upper end opening.

  Thus, the space Ab is allowed to enter each of the game balls falling from the lower opening of the introduction portion Aa so as to be stored therein and to be dropped into the upper end opening of the main guide passage portion Ac as described later. .

  As shown in FIG. 14, the main guide passage portion Ac and the sub guide passage portion Ad both extend downward from the space portion Ab in parallel with each other with the branch wall portion 92e as a boundary wall portion. Has been. The main guide passage portion Ac and the sub guide passage portion Ad have substantially the same opening area at their upper end openings.

  The main guide passage portion Ac is disposed in the right side portion of the left casing member A so as to be positioned below the lower opening portion of the introduction portion Aa through the space portion Ab at the upper end opening portion thereof. For this reason, the main guide passage portion Ac receives the game ball falling through the space Ab from the lower opening of the introduction portion Aa at the upper end opening. The auxiliary guide passage portion Ad is disposed on the left side of the main guide passage portion Ac via the branch wall portion 92e, and corresponds to the width of the auxiliary guide passage portion Ad (the distance between the branch wall portion 92e and the left side wall 92q). Is equal to the width of the main guide passage portion Ac (corresponding to the distance between the branch wall portion 92e and the right side wall 92f).

  In the present embodiment, the introduction part Aa is inclined downward from the left side to the right side as described above. Therefore, the game ball entering the introduction part Aa has both its own weight and the falling speed. Then, it smoothly moves to the right along the lower inner surface of the introduction portion Aa and falls from the lower opening portion of the introduction portion Aa toward the upper end opening portion of the main guide passage portion Ac.

  Therefore, as shown in FIG. 14, the lower opening of the introduction part Aa may face not only the upper end opening of the main guide path part Ac but also the upper end opening of the sub guide path part Ad. The game ball from the lower opening of the introduction part Aa always falls toward the upper end opening of the main guide passage part Ac. In the present embodiment, the game ball from the lower opening of the introduction portion Aa falls toward the upper end opening of the main guide passage portion Ac in the vicinity of the upper end t of the branch wall portion 92e.

  Further, the main guide passage portion Ac is also referred to as middle both curved wall portions 92h and 92m (hereinafter, also referred to as front middle and both curved wall portions 92h and 92m, corresponding to the right middle wall portion of the front side wall portion 92c. FIG. 12 and FIG. 16 (a)), both middle curved walls 92j and 92g (hereinafter, also referred to as rear middle curved walls 92j and 92g) corresponding to the right middle wall of the rear side wall 92d. b)), and the middle wall portion of the right side wall portion 92f and the middle wall portion of the branch wall portion 92e opposed thereto.

  Here, the front middle side curved wall portions 92h and 92m of the front side wall portion 92c are vertically connected to each other so as to incline downward at a predetermined guide inclination angle from the branch wall portion 92e to the right side wall portion 92f. Is formed. In the present embodiment, the predetermined guide inclination angle is set to an angle within a range of 10 ° to 15 °, for example. In addition, the lengths in the inclination direction of both the front middle curved walls 92h and 92m are set to values larger than twice the outer diameter of the game ball and smaller than three times. Further, the predetermined front-rear width (the width direction of the branch wall 92e) of the front middle curved walls 92h, 92m is preferably larger than the outer diameter of the game ball and not more than 1.5 times the outer diameter. It is good to set to the value of. These settings are based on the following grounds.

  That is, in order to supply as many game balls that are sequentially paid out from the ball payout unit 70 toward the upper plate 51 as smoothly as possible, the game balls that fall into the main guide passage portion Ac receive a mutual ball pressure. It is necessary to prevent the occurrence of a situation where a ball is blocked. From such a viewpoint, as described above, the predetermined guide inclination angle is set to, for example, an angle within a range of 10 ° to 15 °, and each of the front and middle curved wall portions 92h and 92m has a length in each inclination direction. The length is set to a predetermined inclination direction length, for example, a value larger than twice the outer diameter of the game ball and smaller than three times, and a predetermined front-rear direction of the front and middle curved walls 92h, 92m. The width is preferably set to a value larger than the outer diameter of the game ball and not more than 1.5 times the outer diameter.

  The predetermined guide inclination angle is not limited to an angle within a range of 10 ° to 15 °, and may be an angle that can smoothly guide the game ball in the inclination direction of the front and middle curved walls 92h and 92m. That's fine. Further, the predetermined inclination direction length and the predetermined front-rear direction width are a value larger than twice the outer diameter of the game ball and smaller than three times and larger than the outer diameter of the game ball, respectively. The value is not limited to a value of 1.5 times or less, and may be any value that is unlikely to generate a ball pressure between adjacent game balls in combination with the predetermined guide inclination angle.

  Further, of the front middle curved walls 92h and 92m, the front middle curved wall 92h is formed in a semi-elliptical longitudinal section convex outward (front) (FIGS. 12 and 16 (a)). )reference). Therefore, the front middle curved wall portion 92h faces the rear middle curved wall portions 92j and 92g in a concave shape with the boundary portion as the center. This means that the front middle curved wall portion 92h faces a concave shape on the spherical passage surface.

  Further, the front middle curved wall portion 92m is formed in an elliptical shape with a quarter longitudinal section convex outward (front side) (see FIGS. 12 and 16B). For this reason, the front middle curved wall portion 92m faces the rear middle curved wall portion 92g in a concave shape with the lower portion as the center. This means that the front middle curved wall portion 92m faces the front middle curved wall portion 92h in a concave shape on the spherical passage surface.

  On the other hand, the rear middle curved walls 92j and 92g of the rear side wall 92d are connected to each other so as to incline downward from the branch wall 92e to the right side wall 92f at the predetermined guide inclination angle. Is formed. In addition, the lengths of the rear middle curved walls 92j and 92g in the inclination direction are set to the predetermined inclination direction lengths, respectively.

  Further, of the rear middle curved walls 92j and 92g, the rear middle curved wall 92j has an elliptical shape with a quarter cross section that protrudes outward (rear side) (see FIG. 16B). The rear middle curved wall portion 92g is formed in a semi-elliptical longitudinal section that protrudes outward (rear side). Here, the lower middle edge portion of the front middle curved wall portion 92h and the upper edge portion of the front middle curved wall portion 92m are connected to each other as a connection edge portion, and the central portion in the vertical direction of the rear middle curved wall portion 92g. The lower edge portion of the rear middle curved wall portion 92j and the upper edge portion of the rear middle curved wall portion 92g are connected to each other as upper and lower portions of the front middle curved wall portion 92h. Opposite the center of the direction.

  This means that the front middle curved wall 92h faces the connecting edges of the rear middle curved walls 92j and 92g in a concave shape, and the rear middle curved wall 92g is both front middle curved walls. This means that the connecting edges of 92h and 92m are opposed to each other in a concave shape. In other words, the front middle curved wall portion 92h faces the connecting edges of the rear middle curved walls 92j and 92g in a concave shape on the spherical passage surface, and the rear middle curved wall 92g This means that the spherical passage faces the connecting edges of the front and middle curved walls 92h and 92m in a concave shape.

  The sub guide passage portion Ad is a middle both curved wall portion 92s, 92w (hereinafter, also referred to as a front middle side curved wall portion 92s, 92w corresponding to the left middle wall portion of the front side wall portion 92c. FIG. 12 and FIG. 16). a)), and both middle curved walls 92r and 92u (hereinafter also referred to as rear middle curved walls 92r and 92u corresponding to the left middle wall of the rear side wall 92d. FIG. 13 and FIG. 16B). See), and the middle wall portion of the left side wall portion 92q and the middle wall portion of the branch wall portion 92e opposed thereto.

  Here, the front middle side curved wall portions 92s and 92w of the front side wall portion 92c are vertically connected to each other and are inclined downward from the branch wall portion 92e to the left side wall portion 92q at the predetermined guide inclination angle. It is formed as follows. Further, the lengths in the inclination direction of the front middle curved walls 92s and 92w are set to the predetermined inclination direction length.

  Of the front middle curved walls 92s and 92w, the front middle curved wall 92s is formed in a semi-elliptical longitudinal section (see FIG. 16A) that protrudes outward (front). The front middle curved wall portion 92w is formed in an elliptical shape with a quarter cross section convex outward (front side) (see FIGS. 12 and 16A).

  On the other hand, the rear middle curved walls 92r and 92u of the rear side wall 92d are connected to each other so as to incline downward from the branch wall 92e to the left wall 92q at the predetermined guide inclination angle. Is formed. In addition, the lengths of the rear middle curved walls 92r and 92u in the inclination direction are set to the predetermined inclination direction length.

  Further, of the rear middle curved walls 92r and 92u, the rear middle curved wall 92r has an elliptical quarter section (see FIG. 16B) that protrudes outward (rear). The rear middle curved wall portion 92u is formed in a semi-elliptical vertical cross section (see FIG. 16B) that protrudes outward (rear side).

  Here, the lower edge portion of the front middle curved wall portion 92s and the upper edge portion of the front middle curved wall portion 92w are connected to each other as a connecting edge portion, and the central portion in the vertical direction of the rear middle curved wall portion 92u. The lower edge portion of the rear middle curved wall portion 92r and the upper edge portion of the rear middle curved wall portion 92u are connected to each other as upper and lower portions of the front middle curved wall portion 92s. Opposite the center of the direction.

  This means that the front middle curved wall 92s faces the connecting edges of the rear middle curved walls 92r and 92u in a concave shape, and the rear middle curved wall 92u This means that the connecting edges of 92s and 92w are opposed to each other in a concave shape. In other words, the front middle curved wall 92s faces the connecting edges of the rear middle curved walls 92r and 92u in a concave shape on the spherical passage surface, and the rear middle curved wall 92u is It means that the spherical passage surface faces the connecting edge portions of the curved front wall portions 92s and 92w in a concave shape.

  In addition, the lower edge portion of the rear middle curved wall portion 92r is set to be lower by a predetermined length than the upper end portion t of the branch wall portion 92e at the width direction end portion on the branch wall portion 92e side. ing. This is to make it difficult for the game ball branched to the auxiliary guide passage portion Ad to return to the main guide passage portion Ac.

  On the other hand, the lower edge portions of the rear middle curved wall portions 92j of the main guide passage portion Ac are branched walls at the lower edge portion of the rear middle curved wall portion 92r at the width direction end portion on the branch wall portion 92e side. It is set so as to be positioned lower than the end in the width direction on the side of the portion 92e by a predetermined length. As described above, the game ball that has dropped from the lower opening portion of the introduction portion Aa onto the lower edge portions of both the rear and middle curved wall portions 92j of the main guide passage portion Ac enters the sub guide passage portion Ad side. This is in order not to let them.

  Moreover, in this embodiment, each curved wall part which forms a part of structure of the main guide passage part Ac and the sub guide passage part Ad becomes a longitudinal cross-section semi-ellipse shape or a quarter ellipse shape. Based on the following grounds.

  That is, when the main guide passage portion Ac and the sub guide passage portion Ad are configured to linearly guide the game balls in the vertical direction, each game ball falls linearly in the vertical direction and the main ball is dropped. There is a risk of clogging of the balls in the guide passage portion Ac and the sub guide passage portion Ad.

  On the other hand, in the present embodiment, as described above, each curved wall portion forming a part of the configuration of the main guide passage portion Ac and the sub guide passage portion Ad has a semi-elliptical longitudinal section or a quarter elliptical shape. Therefore, the inner surface of each curved wall portion changes in a curved shape in the vertical direction. For this reason, each game ball falling into the main guide passage portion Ac and the sub guide passage portion Ad moves downward along one of the inner surfaces (ball passage surfaces) of each curved wall portion, and each lower edge portion thereof It is guided in any inclination direction of the curved wall.

  Thereby, each game ball falling in the main guide passage portion Ac and the sub guide passage portion Ad moves downward along the inner surface (ball passage surface) of each curved wall portion. Then, it is decelerated properly. Therefore, it is possible to eliminate clogging of each game ball in the main guide passage portion Ac and the sub guide passage portion Ad. For this reason, each curved wall portion forming a part of the configuration of the main guide passage portion Ac and the sub guide passage portion Ad has a longitudinal semi-elliptical shape or a quarter elliptical shape.

  In the present embodiment, the horizontal opening width of the main guide passage portion Ac (the horizontal width between the branch wall portion 92e and the right wall portion 92f) is the horizontal width of the lower opening portion of the introduction portion Aa. The horizontal width of the space Ab and the vertical length of the space Ab are set to be smaller. This is for making it harder to generate the ball clogging of the main guide passage portion Ac and the sub guide passage portion Ad.

  Among the rectifying passage portions Ae and Af, the rectifying passage portion Ae includes a vertical wall portion 92n corresponding to the lower right side wall portion of the front side wall portion 92c, and a vertical wall portion 92k corresponding to the lower right side wall portion of the rear side wall portion 92d, The lower wall portion of the right side wall 92f and the lower wall portion of the branch wall portion 92e facing the right wall 92f are configured.

  Here, both the vertical wall portions 92n and 92k extend downward while inclining so as to approach each other from the front middle curved wall portion 92h and the rear middle curved wall portion 92g. The lower wall portion of 92f extends downward while inclining so as to approach the lower wall portion of the branch wall portion 92e. This means that the rectifying passage portion Ae is formed in a converging shape so as to have a rectangular cross section that is narrower downward. In other words, the rectifying passage portion Ae is formed so as to become narrower sequentially downward.

  This is due to the disturbance of the movement of the game ball by dropping each game ball in a curved shape back and forth while being displaced in a curved shape in relation to the shape of each opposing curved wall portion in the main guide passage portion Ac. In view of the possibility of causing ball clogging in the rectifying passage portion Ae, by configuring the rectifying passage portion Ae as described above, each game ball is moved in the width direction by two to smoothly move downward. This is because they are rectified so as to be lined up and moved downward from the outlet portion 92p (see symbol j in FIG. 13).

  Note that the width of the rectifying passage portion Ae (corresponding to the interval between the lower wall portion of the right side wall 92f and the lower wall portion of the branch wall portion 92e) is set somewhat larger than twice the outer diameter of the game ball. ing.

  On the other hand, the rectifying passage portion Af includes a vertical wall portion 92x corresponding to the lower left side wall portion of the front side wall portion 92c, a vertical wall portion 92v corresponding to the lower left side wall portion of the rear side wall portion 92d, a lower wall portion of the left side wall 92q, and It is configured with a lower wall portion of the opposing branch wall portion 92e.

  Here, both the vertical wall portions 92x and 92v are respectively extended downward while being inclined so as to approach each other from the front middle curved wall portion 92w and the rear middle curved wall portion 92u. Further, the lower wall portion of the left side wall 92q extends downward while inclining so as to approach the lower wall portion of the branch wall portion 92e. This means that the rectifying passage portion Af is formed in a constricted shape so as to have a rectangular cross section that becomes narrower downward. In other words, the rectifying passage portion Af is formed so as to become narrower sequentially downward.

  This is due to the disturbance of the movement of the game ball by dropping the game ball downward while displacing the game ball back and forth in relation to the shape of each opposing curved wall portion in the sub guide passage portion Ad. Considering the possibility of ball clogging in the passage portion Af, the rectifying passage portion Af is configured as described above so that each game ball is arranged in the width direction two by two in order to smoothly move downward. This is to rectify and move the outlet 92y downward (see symbol k in FIG. 13).

  The width of the rectifying passage portion Af (corresponding to the interval between the lower wall portion of the left side wall 92f and the lower wall portion of the branch wall portion 92e) is set to be somewhat larger than twice the outer diameter of the game ball. ing.

For this reason, each game ball from the main guide passage portion 101 and the sub guide passage portion 102 does not scatter from the pachinko gaming machine to the hall passage or the like.

  Further, the gaming machine main body Ba is provided with a full tank detection device comprising a full sensor 110 and a control circuit (not shown). The full sensor 110 is connected to the vertical passage unit 80 as shown in FIGS. It is provided as follows.

  The full tank sensor 110 includes a normally open type micro switch, and the full tank sensor 110 includes a tilt lever 111 and a sensor main body 112 (a switch main body 112 of the micro switch).

  Here, in the full tank sensor 110, the sensor main body 112 has a boundary between the two ball guide passages 81 and 82 so as to be located within both intermediate portions of the two ball guide passages 81 and 82 of the vertical passage unit 80. It is fitted into an opening (hereinafter also referred to as a boundary opening) formed in the intermediate portion in the longitudinal direction of the wall. In the present embodiment, the full sensor 110 is maintained in the OFF state as the movable protrusion of the sensor body 112 protrudes forward. Further, the full sensor 110 is maintained in the ON state in accordance with the displacement of the movable protrusion into the sensor body 112. The movable protrusion turns off the switch part built in the sensor main body 112 (corresponding to turning off the full sensor 110) as it protrudes forward. Further, the movable protrusion turns on the switch portion of the sensor body 112 (corresponding to turning on the full sensor 110) in accordance with the displacement into the sensor body 112. The movable protrusion is assembled in the sensor main body 112 so as to be displaceable from the front side and to protrude from the sensor main body 112 to the front side.

  As shown in FIG. 22 or FIG. 23, the tilting lever 111 is supported by the pin 113 at the upper end portion in the boundary opening portions of the both ball guide passages 81 and 82 at the base end portion thereof. Is extended downward along the front surface of the sensor body 112 within the boundary opening from the base end.

  Thus, the tilt lever 111 is pushed forward by the movable protrusion of the sensor main body 112 at the intermediate portion in the extending direction, and the boundary between the both ball guide passages 81 and 82 as shown in FIG. Located in the opening surface of the opening. At this time, the full sensor 110 is in an off state.

  Further, when the game ball is guided downward in either of the both ball guide passages 81 and 82, when the game ball is accumulated near the tilt lever 111, the tilt lever 111 is moved by the pushing surface 111a. The accumulated game ball is pushed toward the sensor body 112 and tilts so as to push the movable protrusion into the sensor body 112 (see FIG. 23).

  Accordingly, the full sensor 110 is turned on. This is because the game balls are accumulated in the path from the inside of the upper plate 51 to the vicinity of the tilting lever 111 in the ball guide passage 81 (hereinafter also referred to as a full tank determination path), or the game balls are sequentially The full tank sensor 110 is turned on only when it accumulates in the path from the inside of the upper plate 52 to the vicinity of the tilting lever 111 in the ball guide passage 82 (hereinafter also referred to as a full tank determination path). By maintaining for a predetermined time, the full state of the game ball is detected.

  The control circuit constitutes a part of the payout control device, and the control circuit determines whether or not the game ball has accumulated in the both full tank determination paths based on the detection output of the full sensor 110. With the determination that it has accumulated, it is determined that the tank is full.

  In the present embodiment configured as described above, it is assumed that the pachinko gaming machine is in a playable state. At this time, the ball tank unit 60 is in a state where a large number of game balls are stored from the tank 61 to both the rectifying paths 62 and 63. The ball dispensing unit 70 closes the upper end portions of both the ball removal passages 76 and 77 by the lid member 78. Further, since the door FD is in the closed state, the ball scattering prevention mechanism 106 allows the game balls to escape from the outlet portions 101b and 102b of the ball passage unit 100 by the longitudinal tilting member 106a. In addition, it is assumed that a large number of game balls are stored in the upper plate 51. Further, it is assumed that game balls are stored from the upper plate 51 to the ball launching device.

  Thus, when the player sequentially fires the game balls by operating the handle H in the pachinko gaming machine, the game balls pass between the inner rail portion 21 and the outer rail portion 22 of the guide rail 20 to play the game. Guided into region 12.

  When each game ball is guided in this way and wins one of the above-mentioned various winning holes, a winning detection signal from a detection switch (not shown) is input to the main board, and a payout instruction is issued from the main board to the payout control board. The command is transmitted, and the payout control board outputs a drive control signal for causing the ball payout device 73 of the ball payout unit 70 to perform a predetermined operation in accordance with the payout instruction command.

  Then, in the ball dispensing device 73, the step motor 73a rotates according to the drive control signal, and the front and rear both-side dispensing cams 73c, 73d rotate by the predetermined angle in the counterclockwise direction shown in FIG. Along with this, a predetermined number of game balls enter the ball dispensing unit 70 from both the inlet passages 71 and 72 through the both rectifying channels 62 and 63 from the ball tank unit 60, and the ball dispensing device 73 It is sequentially sent as a winning ball from both outlet passages 74 and 75 to the vertical passage unit 80 by the front and rear both-side payout cams 73c and 73d.

  Thereafter, the prize balls sent from the outlet passages 74 and 75 in this way are guided by the both ball guide passages 81 and 82 of the vertical passage unit 80, and the ball passages from the outlet portions 81b and 82b. Sent sequentially toward the unit 90. At this stage, since the prize ball does not stay in either of the both ball guide passages 81, 82, the prize ball is full in either of the both ball guide passages 81, 82. Even if 110 is temporarily turned on due to the movement of the prize ball in either of the both ball guide passages 81 and 82, the control circuit does not determine that the tank is full.

  As described above, when the prize balls sequentially move from the outlets 81b and 82b toward the ball path unit 90, the prize balls are introduced into the introduction part Aa of the ball guide path 92 of the ball path unit 90 (see FIG. 14). ) From the upper inlet portion 92a.

  Here, as described above, the introduction portion Aa is inclined from the left side wall 92q to the right side wall 92f of the casing 91 at the predetermined induction inclination angle described above. For this reason, as described above, each winning ball introduced into the introduction portion Aa generates a ball clog along the curved inner surface of the front upper curved wall portion 92b and the curved inner surfaces of the rear upper curved wall portions 92b. Without being guided smoothly in the direction of inclination of the introduction part Aa, it drops from the lower opening of the introduction part Aa through the space Ab toward the main guide passage part Ac (see FIG. 24).

  As described above, each prize ball falling toward the main guide passage portion Ac sequentially falls into the upper end opening of the main guide passage portion Ac. At this time, the branch wall 92e is positioned higher than the branch wall 92a side end of the lower edge of the rear middle curved wall 92j at the upper end t. The prize ball received on the lower edge of the wall 92j does not branch over the upper end t of the branch wall 92e to the auxiliary guide passage part Ad.

  Thus, each prize ball that has dropped into the upper end opening of the main guide passage portion Ac as described above has the curved inner surface of the front middle curved wall portion 92h and the curved inner surfaces of the rear middle curved wall portions 92j and 92g. In between, it guides in a curved shape forward and downward along the curved inner surface of the rear middle curved wall portion 92j.

  Here, as described above, the lower edge portions of the rear middle curved walls 92j are inclined at the predetermined guide inclination angle. Therefore, each prize ball guided in a curved shape downward and forward along the curved inner surface of the rear middle curved wall portion 92j as described above is along the lower edge portion of the rear middle curved wall portion 92j. The vertical middle portion of the front middle curved wall portion 92h and the rear middle curved wall portions 92j while smoothly moving toward the right side wall portion 92f of the casing 91 without receiving ball pressure due to each other. It is smoothly guided downward through a boundary portion of 92g (consisting of a lower edge portion of the rear middle curved wall portion 92j and an upper edge portion of the rear middle curved wall portion 92g (FIG. 16A). 14 and 24).

  Next, each prize ball guided as described above is guided in a curved shape downward and rearward along the curved inner surface of the front middle curved wall portion 92h (FIGS. 16A, 14 and 24). reference).

  Here, as described above, the lower edge portion of the front middle curved wall portion 92h is inclined at the predetermined guide inclination angle. Therefore, each prize ball guided as described above is along the lower edge portion of the front middle curved wall portion 92h, receives the ball pressure from each other, and does not cause clogging of the balls. Smoothly moving toward the boundary between the front middle curved walls 92h and 92m (consisting of the lower edge of the front middle curved wall 92h and the upper edge of the front middle curved wall 92m) and the rear middle It is smoothly guided in a curved manner forward and downward along the curved inner surface of the rear middle curved wall portion 92g through the side curved wall portion 92g (see FIG. 16A, FIG. 14 and FIG. 24). ).

  Each prize ball guided in this way passes through the rectifying passage portion Ae and is sent out from the outlet portion 92p toward the ball passage unit 100 (see FIGS. 14 and 24).

  Here, as described above, the rectifying passage portion Ae is formed in a converging shape so as to have a rectangular cross section narrowing downward toward the branch wall portion 92e. Therefore, even if the movement of the game ball is disturbed by dropping downward while displacing each game ball in a curved shape back and forth in relation to the shape of each opposing curved wall portion in the main guide passage portion Ac. Each award ball can be smoothly sent out from the outlet portion 92p toward the ball passage unit 100 without causing the clogging in the rectification passage portion Ae, with the disturbance being satisfactorily eliminated (see FIGS. 24 and 24). 25).

  As described above, each prize ball sent out from the exit portion 92p of the ball passage unit 90 toward the ball passage unit 100 passes through the main guide passage portion 101 of the ball passage unit 100 and the ball scattering prevention mechanism via the outlet portion 101b. 106.

  At this time, the ball scattering prevention mechanism 106 is in a state in which the game balls are allowed to escape from the outlets 101b and 102b of the ball passage unit 100 by the longitudinal tilting member 106a. For this reason, each winning ball sent to the ball scattering prevention mechanism 106 as described above passes through the ball scattering prevention mechanism 106 and enters the upper plate 51 from the inlet 51a, and receives the tray of the upper plate 51. Stored in the part 51b (see FIG. 24).

  After that, when the gaming state of the pachinko machine becomes a special gaming state in which, for example, the attacker's big winning opening is opened a predetermined number of times and a large number of gaming balls are paid out as prize balls, the inside of the ball tank unit 60 A large number of game balls are sequentially paid out as prize balls by the ball payout unit 70 in the same manner as described above, and pass through both the ball guide passages 81 and 82 of the vertical passage unit 80 toward the ball passage unit 90. Sent sequentially.

  Then, each prize ball sequentially sent out toward the ball passage unit 90 in this way sequentially passes through the introduction portion Aa and the space portion Ab of the ball passage unit 90 toward the main guide passage portion Ac in the same manner as described above. Then, in the main guide passage portion Ac, it is smoothly guided downward in the front-rear direction without causing clogging in the same manner as described above, and is smoothly sent out to the ball passage unit 100. Each prize ball sent out in this way passes through the main guide passage portion 101 of the ball passage unit 100 and the ball scattering prevention mechanism 106 and is stored in the tray portion 51b of the upper plate 51.

  In such a process, the award ball is filled with the upper plate 51, and then reaches the upper end opening of the main guide passage portion 101 of the ball passage unit 100 and the main guide passage portion Ac of the ball passage unit 90. When it is full, the prize balls that subsequently fall through the space Ab will fall sequentially onto the prize balls that are full up to the upper end opening of the main guide passage part Ac (FIGS. 26 and 27). reference).

  Therefore, each prize ball falling on the prize ball that has been filled up to the upper end opening of the main guide passage portion Ac is positioned above the upper end t (see FIG. 14) of the branch wall 92e. Will come to do. For this reason, each such award ball is branched to the auxiliary guide passage portion Ad side beyond the upper end portion t of the branch wall portion 92e, and enters the upper end opening of the auxiliary guide passage portion Ad (FIG. (See arrow at 27).

  The prize balls that are branched into the upper end opening of the auxiliary guide passage portion Ad in this way enter the curved inner surface (ball passage surface) of the front middle curved wall portion 92s and the rear middle curved wall portions 92r, Between each curved inner surface (spherical passage surface) of 92u, it is guided in a curved shape forward and downward along the curved inner surface of the rear middle curved wall portion 92r.

  Here, as described above, the lower edge portions of the rear middle curved walls 92r are inclined in the opposite direction to the lower edges of the rear middle curved walls 92j at the predetermined guide inclination angle. Yes. Therefore, as described above, each prize ball guided in a curved shape downward and forward along the curved inner surface (spherical passage surface) of the rear middle curved wall portion 92r is below the rear middle curved wall portion 92r. Both the center and the rear middle side of the front middle curved wall 92s are smoothly moved toward the left wall 92q of the casing 91 along the edge without receiving ball pressure from each other and causing clogging. Smoothly guided downward through the boundary between the curved walls 92r, 92u (consisting of the lower edge of the rear middle curved wall 92r and the upper edge of the rear middle curved wall 92u) (see FIG. 16 (b), FIG. 14 and FIG. 28).

  Next, each prize ball guided in this way is guided in a curved shape downward and rearward along the curved inner surface of the front middle curved wall portion 92s (see FIG. 16B, FIG. 14 and FIG. 28). ).

  Here, as described above, the lower edge portion of the front middle curved wall portion 92s is inclined in the direction opposite to the lower edge portion of the front middle curved wall portion 92h at the predetermined guide inclination angle. Therefore, each prize ball guided as described above is along the lower edge portion of the front middle curved wall portion 92s, receives the ball pressure from each other, and does not cause clogging of the balls. Smoothly moving toward the boundary between the front middle curved walls 92s and 92w (consisting of the lower edge of the front middle curved wall 92s and the upper edge of the front middle curved wall 92w) and the rear middle It is smoothly guided in a curved shape forward and downward along the curved inner surface of the rear middle curved wall portion 92u through the side curved wall portion 92u (see FIG. 16B, FIG. 14 and FIG. 28). ).

  Each prize ball guided in this way passes through the rectifying passage portion Af and is sent out from the outlet portion 92y toward the ball passage unit 100 (see FIGS. 14 and 28).

  Here, as described above, as shown in FIG. 14, the rectifying passage portion Af is formed in a converging shape so as to have a rectangular cross section that is narrower toward the lower side toward the branch wall portion 92e. Therefore, even if the movement of the game ball is disturbed by dropping downward while displacing each game ball in a curved shape back and forth in relation to the shape of each opposing curved wall portion in the sub guide passage portion Ad. Each award ball can be smoothly sent out from the exit portion 92y toward the ball path unit 100 without causing the clogging in the rectifying path portion Afe, with the disturbance being satisfactorily eliminated (see FIG. 28). .

  As described above, each prize ball sent out from the exit portion 92y of the ball passage unit 90 toward the ball passage unit 100 passes through the sub guide passage portion 102 of the ball passage unit 100 and passes through the outlet portion 102b. 106.

  At this time, the ball scattering prevention mechanism 106 is in a state in which the game balls are allowed to escape from the outlet portions 101b and 102b of the ball passage unit 100 by the longitudinal tilting member 106a, as described above. Therefore, each prize ball sent to the ball scattering prevention mechanism 106 as described above passes through the ball scattering prevention mechanism 106 and enters the lower plate 52 from the outlet 51e through the passage 51d of the upper plate 51. Stored.

  In such a process, the award ball is filled in the lower plate 52 under the special gaming state described above, and then the auxiliary guide passage portion 102 of the ball passage unit 100 and the sub-passage of the ball passage unit 90 are filled. The upper end opening of the guide passage portion Ac becomes full, and further, stays from the space portion Ab through the introduction portion Aa to each corresponding portion of the both ball guide passages 81 and 82 of the vertical passage unit 80 with respect to the full tank sensor 110. Then, the full sensor 110 is pushed on by the award ball staying on the pushing surface 111a of the movable lever 111 as described above, and turns on.

  Such a state is maintained for the predetermined time due to the stay of the prize balls as described above. This means that the full tank sensor 110 has a prize ball corresponding to the full tank sensor 110 out of the ball guide paths 81 and 82 of the lower plate 52 to the upper plate 51, the ball passage unit 100, the ball passage unit 90 and the vertical passage unit 80. In other words, it means that each corresponding portion is in a full state due to staying over both the above-described full tank determination paths. Therefore, the control circuit determines that the tank is full.

  Accordingly, for example, if the image display displays that the game ball is to be pulled out from the lower plate 52 based on the determination that the control circuit is full, the player can use the lower plate 52 based on the display. Pull out the game ball inside. Then, as described above, a large number of prize balls staying in the full tank determination path and becoming full are sequentially stored in the lower dish 52 in the same manner as described above. Such a ball removal process is repeated each time the game balls in the lower plate 52 are full.

  Here, in the ball passage unit 90, the lower edge portion of each opposing curved wall portion in the main guide passage portion Ac is as described above with respect to the lower edge portion of each opposing curved wall portion in the sub guide passage portion Ad. Inclined in directions away from the branch wall portion 92e in opposite directions. In addition, the width of each opposing curved wall is set to a value that is greater than twice the outer diameter of the game ball and less than three times.

  For this reason, each time the ball in the lower plate 52 is removed, a large number of award balls staying and filling the both full tank judgment paths are filled in the auxiliary guide passage portion Ad as described above. It is possible to smoothly enter the lower plate 52 while preventing the ball from clogging. The same applies to the main guide passage portion Ac. This means that even if the tank is full as described above, if the ball is removed from the lower plate 52 or the like, the award ball is smoothly sent to the lower plate 52 or the like without causing a ball clogging in the ball passage unit 90. Means that you can.

  Further, as described above, the full tank sensor 110 is disposed together with the passage unit 80 on the main body frame BF of the gaming machine main body Ba which is a so-called inner frame, and the full tank sensor 110 is connected to the both ball guide passages 81 of the passage unit 80. , 82 is provided at the intermediate portion in the longitudinal direction.

  Therefore, the prize ball is not only staying between the lower plate 52 and the ball passage unit 90 but also corresponding to the full tank sensor 110 in the ball passage unit 90 and the ball guide passages 81 and 82 of the passage unit 80. It is determined that the tank is full only when it stays at the site.

  Therefore, the number of storage in the pachinko machine until the game ball is full can be greatly increased, and as a result, the player can ease the feeling of rushing out of the ball, In recent years, even if the size of the hall is increasing, it is possible to lengthen the time required to exchange the dollar box required for ball removal, and as a result, it is possible to reduce the burden of rushing the exchange of the dollar box. .

  Furthermore, since the distance from the lower plate 52 to each corresponding portion of the both ball guide passages 81 and 82 of the passage unit 80 with respect to the full tank sensor 110 is increased, the frequency at which the player fills up the game ball is reduced. As a result, it is difficult for the ball management error to occur during a special prize game or a so-called electric tulip support game.

  When the game balls necessary for the game remain in the upper plate 51 through the above-described ball removal process, the player smoothly starts the game again in a state where there is no ball clogging as described above. It will be.

  As described above, according to the present embodiment, in the ball passage unit 90, each game ball introduced as a prize ball from the upper entrance portion 92a to the introduction portion Aa is a lower opening portion of the introduction portion Aa. And then sequentially dropped through the space Ab and received by the main guide passage portion Ac. At this time, the main guide passage portion Ac extends downward from the introduction portion Aa via the space portion Ab so as to face the lower opening of the introduction portion Aa via the space portion Ab. Each falling game ball is received by the main guide passage portion Ac without being branched to the sub guide passage portion Ad side.

  Here, in the main guide passage portion Ac, the one-side curved wall portion 92h is formed in a convex shape in a longitudinal section in a downward direction in a direction away from the branch wall portion 92e, and below the one-side curved wall portion 92h. The edge portion is inclined at a predetermined guide inclination angle downward in a direction away from the branch wall portion 92e.

  Further, in the main guide passage portion Ac, the other-side up-and-down curved wall portions 92j and 92g are connected vertically so as to face the concave portion in the longitudinal section with respect to the one-side curved wall portion 92h side. The lower edge portion of the upper curved wall portion 92j of the wall portions 92j and 92g, together with the upper edge portion of the lower curved wall portion 92g, faces the vertical center portion of the one-side curved wall portion 92h and is away from the branch wall portion 92e. Are inclined downward at the predetermined guide inclination angle.

  Accordingly, each of the game balls sequentially received by the main guide passage portion Ac as described above falls down along the curved inner surface of the upper curved wall portion 92j in the main guide passage portion Ac, while the upper curved wall. Guided downward while moving in the direction of inclination along the lower edge of the portion 92j, and then falling downward along the curved inner surface of the one-side curved wall 92h, the lower edge of the one-side curved wall 92h It is guided further downward while moving in the inclination direction along the top. This means that even if there are many game balls that are sequentially received in the main guide passage portion Ac, each of the game balls is based on the curved shape of the upper curved wall portion 92j and the curved shape of the one-side curved wall portion 92h. This means that the guide is smoothly guided in the main guide passage portion Ac without causing clogging based on the predetermined guide inclination angle.

  When the number of game balls received by the main guide passage portion Ac increases and stays in the upper end opening of the main guide passage portion Ac, each staying game ball passes through the upper end portion t of the branch wall portion 92e. Branching into the auxiliary guide passage portion Ad.

  Here, the one side curved wall portion 92s and the other side upper and lower curved wall portions 92r and 92u of the sub guide passage portion Ad are respectively connected to the one side curved wall portion 92h and the other side upper and lower curved wall portions 92j and 92g of the main guide passage portion Ac. Similarly, the lower edge portion of the upper curved wall portion 92r and the upper curved wall portion 92r of the other side upper and lower curved wall portions 92r and 92u and the lower edge portion of the one side curved wall portion 92s are arranged on one side of the main guide passage portion Ac. The lower edge portion of the curved wall portion 92h and the lower edge portion of the upper curved wall portion 92j are inclined in a direction away from the branch wall portion 92e in the opposite direction.

  Accordingly, each of the game balls that sequentially enter the auxiliary guide passage portion Ad as described above falls downward along the curved inner surface of the upper curved wall portion 92r in the auxiliary guide passage portion Ad, and the upper curved wall portion 92r. It is guided downward while moving in the inclination direction along the lower edge of the lower side, and then falls downward along the curved inner surface of the one side curved wall 92s and onto the lower edge of the one side curved wall 92s. It is guided further downward while moving in the inclination direction. This means that even if there are many game balls branched to the sub guide passage portion Ad, each of the game balls is based on the curved shape of the upper curved wall portion 92r and the curved shape of the one-side curved wall portion 92s. It means that the guide is smoothly guided in the auxiliary guide passage portion Ad without causing a ball clogging based on a predetermined guide inclination angle.

  Here, in the present embodiment, the introduction portion Aa of the ball passage unit 90 is inclined in the same direction as the lower edge portion of the upper curved wall portion 92j of the main guide passage portion aC and the upper edge portion of the lower curved wall portion 92g. ing.

  Thereby, each game ball introduced into the introduction portion Aa is the same as the lower edge portion of the upper curved wall portion 92j of the main guide passage portion Ac and the upper edge portion of the lower curved wall portion 92g within the introduction portion Aa. Since each of the game balls moves in the direction, the game ball can surely fall into the main guide passage portion Ac from the lower opening of the introduction portion Aa without dropping to the sub guide passage portion Ad side.

  Further, in the present embodiment, as described above, in the ball passage unit 90, the main guide passage portion Ac and the sub guide passage portion Ad have the outer diameters of the game balls at the inclination direction lengths of the respective curved wall portions. It is set to a value larger than twice and smaller than three times. Accordingly, each game ball moving in an inclined manner in the main guide passage portion Ac and the sub guide passage portion Ad moves smoothly without receiving a ball pressure from each other in combination with the predetermined guide inclination angle. can do.

  In the present embodiment, in the passage unit 90, the main guide passage portion Ac receives each game ball falling from the lower opening of the introduction portion Aa in the vicinity of the upper end portion t of the branch wall portion 92e. The upper curved wall portion 92j of the main guide passage portion Ac is formed at the lower edge of the upper guide wall portion Aa of the auxiliary guide passage portion Ad. It is formed so as to be located below the lower edge portion of the portion 92r. In addition, the branch wall portion 92e is formed at the upper end portion so as to protrude above the lower edge portion of the upper curved wall portion 92r of the sub guide passage portion Ad with a length less than the outer diameter of the game ball. Has been.

  Therefore, the lower edge portion of the upper curved wall portion 92j of the main guide passage portion Ac is located below the lower edge portion of the upper curved wall portion 92r of the sub guide passage portion Ad, and the upper end of the branch wall portion 92e. Since the portion t has a length less than the outer diameter of the game ball and protrudes upward from the lower edge portion of the upper curved wall portion 92r of the auxiliary guide passage portion Ad, each game ball has a branch wall portion 92e. Even if it falls on the lower edge part of the upper side curved wall part 92j from the lower side opening part of the introduction part Aa so that it may be received in the vicinity of the upper end part t, the said each game ball of the branch wall part 92e It can be reliably received by the main guide passage portion Aa without branching to the sub guide passage portion Ad side beyond the upper end portion t.

  In the present embodiment, as described above, the two rectifying passage portions Ae and Af extending along the both sides of the branch wall portion 92e from the main guide passage portion Ac and the sub guide passage portion Ad have a rectangular cross section that is narrower toward the lower side. It is formed in a constricted shape so as to have a shape.

  For this reason, in relation to the shape of each opposing curved wall portion in the main guide passage portion Ac and the sub guide passage portion Ad, disturbance of the movement of the game ball by dropping each game ball downward while being displaced back and forth Even if this occurs, both the rectifying passage portions Ae and Af can be smoothly rectified by rectifying the game balls so that two game balls are arranged in the width direction two by one in the above-described configuration.

  According to the above, in the present embodiment, by adopting the ball passage unit 90 configured as described above, even if a large number of prize balls stay in the hollow sphere guide passage 92 in a full state, the hollow If the prize ball staying below the spherical ball guide passage 92 moves downward, for example, by pulling out the game ball in the lower plate 52, the prize ball staying in the hollow ball guide passage 92 However, in the inside of the main guide passage portion Ac and the inside of the sub guide passage portion Ad, the curved wall portion is smoothly moved without clogging in the bending direction of the curved wall portion and the inclined direction of the lower edge portion of the curved wall portion. And guided down. As described above, since the game ball is received in the main guide passage portion Ac in the vicinity of the upper end t of the branch wall portion 92e, the inclination direction of the curved wall portion of the main guide passage portion Ac of the game ball Guidance can be made well.

  And, in the main guide passage portion Ac and the sub guide passage portion Ad, due to the relationship with the shape of each opposing curved wall portion, the movement of the prize ball is disturbed by sending each prize ball downward while displacing the prize ball back and forth. Each award ball can be rectified well by each rectifying passage portion and sent to the upper plate 51 and the lower plate 52 without causing the resulting ball clogging inside the rectifying passage portion in the above-described configuration. it can.

In carrying out the present invention, the ball passage unit according to the present invention described in the above embodiment is
