  A tank 18 capable of storing game balls is provided in the upper part on the back side of the pachinko gaming machine 10. The tank 18 is formed in a dish shape that is long in the width direction and opens upward. The tank 18 corresponds to a supply unit referred to in the present invention, and the tank 18 is supplied with game balls from a game ball supply device installed in a hall or the like. By providing the tank 18 in the upper part of the gaming machine, it is possible to distribute the gaming ball using the momentum that the gaming ball is drawn by gravity and flows down. The bottom surface of the tank 18 is formed so that the right side of the paper is lower, and the game ball flowing down in the tank 18 flows in the right direction of the paper.

  A hole is formed in the bottom surface of the tank 18, and a game ball falls on the tank rail 18a from the hole. The tank rail 18a is inclined so that the right side of the paper surface is lowered, and the game ball that has dropped on the tank rail 18a flows down to the right side of the paper surface. Furthermore, the game ball falls on the payout device 19 provided below the right end of the tank rail 18a. The payout device 19 has a passage 19a having an inner diameter approximately equal to the diameter of the game ball, and a rotating body 19b having a predetermined shape is provided on the side of the passage 19a, and a part of the rotating body 19b is part of the passage 19a.

  For example, when a big hit is made, the CPU or the like commands the rotating body 19b to rotate at high speed. Conversely, when there is no prize ball, the CPU or the like instructs to stop the rotating body 19b. The passage 19 a communicates with the inside of the guide member 20 provided below the payout device 19, and the game ball paid out by the payout device 19 falls into the guide member 20.

  FIG. 4 schematically shows the path of the game ball. In the figure, the guide member 20 has a substantially L-shaped passage 20a therein, and the bottom surface of the passage 20a is inclined so as to become lower toward the front. The front end portion of the passage 20a is open, and the game ball flowing down along the bottom surface can be discharged forward. The opening at the front end of the passage 20a is connected to the rear end of the mechanism plate passage 17a formed so as to penetrate the mechanism plate 17 in the front-rear direction. Accordingly, the game ball discharged from the guide member 20 is introduced into the mechanism plate passage 17a. Since the bottom surface of the mechanism plate passage 17a is inclined so as to become lower toward the front, the game ball introduced into the mechanism plate passage 17a flows further forward.

  Although the mechanism plate 17 is pivotally supported with respect to the main body frame 12, the mechanism plate 17 and the main body are rotated by rotating the mechanism plate 17 so that the mechanism plate 17 and the main body frame 12 are parallel to each other. The frame 12 is in close contact with the frame 12. At this time, the front end of the mechanism plate passage 17a is also in contact with the main body frame 12 from the back side, and is connected to the rear end of the game board passage 24a formed so as to penetrate the game board 24 fitted in the main body frame 12 back and forth. To do. By doing in this way, the game ball which flowed down the mechanism board channel | path 17a can be guided to the game board channel | path 24a. Since the bottom surface of the game board passage 24a is inclined so as to become lower toward the front, the game balls introduced into the game board passage 24a further flow down through the game board passage 24a.

  On the other hand, a front passage 30 is attached to the glass frame 13 provided on the front side of the main body frame 12 so as to penetrate the glass frame 13 back and forth. Although the glass frame 13 is pivotally supported with respect to the main body frame 12, the glass frame 13 is rotated so as to close the back side of the main body frame 12 and close the game area 25 from the front side. Sometimes, the glass frame 13 and the game board 24 held by the main body frame 12 can be brought into close contact with each other in parallel. At this time, the entry portion 30 a protruding from the glass frame 13 on the back side approaches the game board 24, and the tip portion of the entry portion 30 a is inserted into the recess 24 b formed on the front surface of the game board 24. On the front surface of the game board 24, a recess 24b is formed so as to surround the opening of the game board passage 24a in a front view.

  FIG. 5 shows the state immediately before the glass frame 13 is rotated so as to close the game area 25 from the front side and the entry portion 30a enters the recess 24b. In the same figure, the entrance part 30a gradually approaches the recessed part 24b by rotating the glass frame 13 so as to close the game area 25 from the front side. Since the tip portion of the entry portion 30a is formed horizontally, the approach portion 30a approaches the game board 24 vertically at a certain height. Strictly speaking, since the entrance portion 30a rotates together with the glass frame 13, the approach portion 30a approaches the recess 24b at a constant height while drawing a horizontal orbit in the horizontal direction. The recess 24b is formed in a groove shape having a predetermined depth, and is formed by cutting the wooden game board 24 from the front side. The diameter of the recess 24b is approximately the same as the diameter of the entry portion 30a, and the groove width of the recess 24b is larger than the thickness of the entry portion 30a, so that the entry portion 30a enters the recess 24b. , Can be in an intricate state. Since the groove width of the recess 24b is larger than the thickness of the entry portion 30a, the entry portion 30a is allowed to enter the recess 24b without interference by the entry portion 30a that moves circumferentially in the horizontal direction. be able to.

  When the entry portion 30a enters the recess 24b, the opening of the game board passage 24a is surrounded from the outside by the entry portion 30a constituting the short portion of the front passage 30, so that the game ball passes from the game board passage 24a to the front passage 30. Can be introduced. That is, the game board passage 24a and the front passage 30 are connected. Since the upper part of the front passage 30 is inclined so as to become lower toward the front, the game ball introduced into the upper part of the front passage 30 flows further forward.

  In this way, the mechanism plate passage 17a and the game board passage 24a penetrating the front and rear of each member constituting the pachinko gaming machine 10 are formed, and these are connected to the front and rear, so that the main body of the pachinko gaming machine 10 is moved forward and backward. A main body side passage A can be formed. According to the main body side passage A, the game balls can be circulated from the back side to the front side, so that the game balls paid out from the payout device 19 can flow into the front side passage 30 on the front side. The game balls flowing down the front passage 30 can be supplied to the upper plate 14 using the upper plate passage 34.

  Further, by providing the concave-convex structure in which the entry portion 30a enters the recess 24b, it is possible to prevent foreign matter from entering the connection portion between the front passage 30 and the main body passage A. In FIG. 4, when the entry portion 30a and the recess 24b are engaged with each other, the gap shape between them can be bent into a substantially U-shape. Therefore, it is possible to prevent the game ball inside the entry portion 30a from entering the foreign body from the outside with respect to the circulation passage. Even if the glass frame 13 is rotated so that the game area 25 is closed, there is a slight gap between the front side of the main body configured by the main body frame 12 and the game board 24 and the back side of the glass frame 13. Although a gap is formed, it is possible to prevent the long and thin foreign matter that has entered along the gap with a gap shape that is bent in a substantially U-shape.

(2) Second embodiment:
FIG. 6 shows a cross section of a connection portion between the front passage and the main body passage according to the second embodiment. In the same figure, the protrusion part 130a is formed by making the edge part of the front channel | path 130 protrude from the glass frame 113 to the back side. A protective member 190 that surrounds the protrusion 130a from the outside in a circumferential shape is attached to the back side of the glass frame 113. FIG. 7 shows the protective member 190 as viewed from an oblique direction. In the figure, the protective member 190 has a cylindrical protective cylinder 191, and the inner side of the protective cylinder 191 penetrates in the axial direction. By extending one end of the protective cylinder 191 radially outward, a donut plate-shaped attachment portion 192 having a circular opening at the center is formed. A plurality of screw holes 192a, 192a, 192a are formed in the attachment portion 192.

  In FIG. 6, the protective member 190 is attached so that the attachment portion 192 is in close contact with the back side of the glass frame 113. The protective member 190 is attached to the glass frame 113 by screwing screws into the glass frame 113 using the screw holes 192a, 192a, 192a. In a state where the protection member 190 is attached, the lengths of the protruding portion 130a and the protective cylinder 191 are set so that the end of the protective cylinder 191 is positioned on the back side by a predetermined amount from the end of the protruding portion 130a. . In addition, in the state where the protection member 190 is attached, the axial direction of the protection cylinder 191 is horizontal. In the present embodiment, the protrusion 130a is inclined to the tip on the back side.

  In FIG. 8, the glass frame 113 is rotated so as to approach the game board 124, and at this time, the game area formed on the front side of the game board 124 is closed from the front side by the glass frame 113. The In the figure, the tip of the projecting portion 130 a is in contact with the game board 124. Since the position of the rear side end portion of the protrusion 130a and the position of the opening on the front side of the game board passage 124a coincide with each other, the game board passage 124a and the protrusion 130a can be connected. Since the protrusion 130a is inclined to the tip at an inclination angle similar to the inclination angle of the game board passage 124a, a substantially continuous game ball passage can be formed by the protrusion 130a and the game board passage 124a. Therefore, the game balls can be flowed in an orderly manner at the connection portion between the projecting portion 130a and the game board passage 124a, and the collision of the game balls can be prevented.

  On the other hand, the tip of the protective cylinder 191 formed so as to protrude rearward from the protruding portion 130a enters the recessed portion 124b formed in the game board 124, and is in an intricate state. Similar to the previous embodiment, a recess 124b is formed on the front surface of the game board 124 so as to surround the opening of the game board passage 124a in a front view. Since the diameter of the recess 124b is approximately the same as the diameter of the protective cylinder 191 and the groove width of the recess 124b is larger than the thickness of the protective cylinder 191, the protective cylinder 191 is larger than the recess 124b. It can enter horizontally and be in an intricate state.

  In this way, the protective cylinder 191 is formed so as to surround the outside of the connection portion between the front passage 130 and the game board passage 124 a, and the protective cylinder 191 is assembled into the game board 124 so that the front cylinder It can protect from the outside of the connection location of 130 and the game board passage 124a. Since the protective cylinder 191 is assembled in the game board 124, the shape of the gap between the two becomes complicated, and foreign matter can be prevented from entering through the gap. Further, since the protruding portion 130a constituting the rear side end portion of the front passage is not inserted into the concave portion 124b, the tip of the protruding portion 130a does not need to be perpendicular to the game board 124. Therefore, it is possible to incline to the tip of the projecting portion 130a, and it is possible to realize smooth joining with the game board passage 124a.

(3) Third embodiment:
FIG. 9 shows a cross-section of a connection portion between the front passage and the main body passage according to the third embodiment. In the figure, a through hole 224c in the horizontal (front-rear) direction is formed in the game board 224, and a member to be entered 290 is attached to the through hole 224c.

  In FIG. 10, a game board passage 292a is opened in a rectangular shape at the central portion of the collar portion 291 and a concave portion 291a is formed so as to surround the outside in a circumferential shape. The recess 291a is formed in a circular groove shape, and has a predetermined width and depth. In FIG. 9, the insertion member 290 is inserted into the through hole 224c toward the back side, and the flange 291 is in close contact with the periphery of the front side opening of the through hole 224c. Since the width and height of the through hole 224c are slightly larger than the insertion portion 292, when the insertion portion 292 is inserted into the through hole 224c, the flange portion 291 is located around the front side opening of the through hole 224c. Abut. The concave portion 291a formed in the flange portion 291 faces the front side. The distal end of the insertion portion 292 reaches the mechanism plate 217 and is continuously connected to the mechanism plate passage 217a formed in the mechanism plate 217.

  Then, in a state where the member to be entered 290 is mounted, the glass frame 213 is rotated so that the game area is closed, and the glass frame 213 is brought closer to the game board 224. The entrance part 230a formed by projecting from the back side enters the recessed part 291a facing the front side at the flange part 291 and enters an intricate state. As described above, the member to be entered 290 may be attached to the game board 224 so that the front passage 230 is complicated with respect to the member to be entered 290. Even in this case, similarly to the first embodiment, the connection portion between the main body side passage A and the front passage 230 can be protected by the concavo-convex structure including the concave portion 291a and the entry portion 230a. With such a configuration, since the shape of the game board 224 can be simplified, the processing of the game board 224 can be simplified. In this embodiment, the game board passage 292a, the mechanism plate passage 217a, and the passage 220a constitute the main body side passage A.

And the protection member 490 is attached so that one end may be inserted in the through-hole 424c. FIG. 13 shows the protective member 490 as seen from an oblique direction. In the figure, a substantially prismatic insertion portion 491 and a substantially cylindrical protection portion 493, each having an axial direction oriented in the front-rear direction, are connected by a disk flange-like flange portion 492. A plurality of screw holes 492a, 492a, 492a are formed in the flange portion 492.

  Since the width and height of the insertion portion 491 are slightly smaller than the through hole 424c, the insertion portion 491 can be inserted into the through hole 424c as shown in FIG. When the insertion portion 491 is inserted into the through hole 424c, the distal end of the insertion portion 491 reaches the mechanism plate 417, and the flange portion 492 is in close contact with the periphery of the front side opening of the through hole 424c in the game board 424. Then, the protection member 490 can be fixed to the game board 424 using the screw holes 492a, 492a, 492a. Then, the protection part 493 protrudes vertically from the game board 424 toward the front side. Since the game board 424 is held vertically, the axial direction of the protection part 493 is horizontal. A protection passage 490 a is formed across the insertion portion 491, the flange portion 492, and the protection portion 493.

  The protective passage 490a opens to the back side at the distal end of the insertion portion 491, and is connected to a mechanism plate passage 417a formed in the mechanism plate 417 through the opening. The protective passage 490a is inclined so that the bottom surface is lowered toward the front side, and the direction of the passage is bent near the front side end of the protective portion 493 and opens downward. Thereby, the game ball guided from the mechanism plate passage 417a can flow down to the protection part 493, and the game ball can be released downward from the vicinity of the tip of the protection part 493.

  FIG. 14 shows a state where the glass frame 413 is rotated so that the game area is closed in a state where the protection member 490 is attached. As shown in the figure, when the glass frame 413 is moved closer to the game board 424, a protective portion 493 protruding from the game board 424 to the front side is provided inside the front passage 430 protruding from the glass frame 413 to the front side. Inserted, the protection part 493 and the front passage 430 are complicated. The upper part of the front passage 430 is connected to the glass frame 413 at the same height as the protection part 493 and is formed in a cylindrical shape with a horizontal axial direction. Since the inner diameter of the upper portion of the front passage 430 is slightly larger than the outer shape of the protection portion 493, the protection portion 493 that moves relatively horizontally can be inserted inside the front passage 430.

  When the glass frame 413 is rotated until the gaming area is completely closed, the bent positions of the protection part 493 and the front passage 430 coincide with each other, and the front passage 430 is opened from the lower opening formed near the tip of the protection part 493. A game ball can be dropped on a vertical part.

  In this way, by entering the protective member 490 inside the front passage 430, it is possible to prevent foreign matter from entering the passage of the game ball. Since the front passage 430 protrudes from the front side of the glass frame 413, fraud is likely to occur. However, at least the upper part of the front passage 430 can be made to have a double structure by the protection part 493, and fraud can be prevented. In particular, by strengthening protection for the upper part of the front passage 430, fraud to the payout device 419 disposed relatively close to the upper part can be effectively prevented, and the number of game balls to be paid out is illegal. Can be prevented from being controlled. Note that by using metal as the material of the protection member 490, high anti-fraud property can be realized.

(6) Sixth embodiment:
FIG. 15 shows a pachilot as a gaming machine according to the sixth embodiment as seen from an oblique direction. The pachilot 510 uses game balls instead of medals in the slot machine. For example, five pachinko balls can be equivalent to one medal and enjoy a game. The pachilot 510 is provided with a drum 525a that rotates as in the slot machine. In such a pachilot 510, since a game ball is used as a game medium, the game ball is paid out according to the game state. Accordingly, the front passage 530 can be attached to the window frame 513 of the pacilot 510, thereby ensuring a wide space on the back side of the pacilot 510. An opening is formed in the window frame 513 in which the window frame 513 is pivotally supported with respect to the main body 511, and the inner drum 525a can be visually recognized through the opening. Even in such a configuration, it is possible to form a concavo-convex structure in a state of being entangled between the window frame 513 and the main body 511.

(7) Summary:
In the present invention, it is possible to prevent foreign matter from entering the connecting portion between the front passage 30 and the main body side passage A by providing a concave-convex structure in which the entry portion 30a enters the concave portion 24b. By engaging the entry portion 30a and the recess 24b, the shape of the gap between them can be bent into a substantially U-shape. Therefore, it is possible to prevent the game ball inside the entry portion 30a from entering from the outside with respect to the circulation passage.
