  In the award winning device of the gaming machine shown in Patent Document 1, a set of shaft support plates provided with shaft holes in advance is prepared to attach the doors to the front surface of the case body, and the doors are opened to these shaft holes. After the rotation shaft is inserted from the center axis direction, both the shaft support plates are screwed to the front surface of the case body to attach the opening / closing door. In this way, a set of shaft support plates are prepared separately, and these shaft support plates must be screwed to the front surface of the case body, which necessitates troublesome work and poor workability in assembly, as well as the number of parts. There was a point that should be improved that the production cost increased.

  As described above, the pivotal support plate that is attached to the front surface of the case body by screwing is required because the pivot shaft protrudes outward from both ends of the lower side of the opening / closing door, and the pivot shaft is The shaft hole is inserted into the shaft hole from the center axis direction. If the shaft support plate corresponding to the bearing of the rotating shaft is fixed to the case body first, both the opening and closing doors are inserted into the shaft holes. This is because the rotation shaft cannot be inserted in dimension.

  Therefore, the present invention has been made in view of the above problems, and the rotation shaft can be directly inserted into the bearing portion provided on the front side of the case body, thereby improving workability and reducing the number of parts, thereby reducing the production cost. It is an object of the present invention to provide a gaming machine winning device that can be made inexpensively.

  In order to achieve such an object, a game machine winning device according to the present invention includes a mounting board that is attached to a game board surface and has a ball entrance for winning a game ball, and a mounting board that surrounds the ball entrance. A case body attached to the rear side, and an opening / closing door that is disposed on the front side of the case body and pivots up and down in the front-rear direction with an electric actuator as a fulcrum to open and close the ball entrance. A gaming machine winning device provided with a pivot shaft projecting from both ends of the lower side portion of the open / close door along the lower side portion, and provided with a bearing portion through which the pivot shaft is inserted on the front side of the case body A D-cut surface obtained by cutting a part of the peripheral surface into a planar shape along the axial direction is formed on the rotating shaft, and each bearing portion is attached from a direction orthogonal to the central axis of the bearing portion. So that the D-cut surface is substantially parallel to the insertion direction. Then, the insertion range in which the rotation shaft can be inserted is opened, and the rotation range from the position where the opening / closing door is erected to block the ball entrance to the front side and the ball entrance is opened Inside, the direction of the D-cut surface with respect to the insertion port is set so that the rotating shaft inserted through the bearing portion does not unnecessarily come out of the insertion port.

  At this time, a ball outlet is formed in the case body to discharge the winning game ball from the ball entrance downward, and a ball detector is disposed at the ball outlet so as to incline forward, that is, toward the ball entrance. It is preferable that the winning game ball is directly guided to the ball opening of the ball detector and dropped.

  In the gaming machine winning device according to the present invention, a D-cut surface obtained by cutting a part of the peripheral surface into a planar shape along the axial direction is formed on the rotation shaft, and the bearing portion is centered on the center axis of the bearing portion. An insertion port that allows insertion of the rotating shaft was opened so that the D-cut surface was almost parallel to the insertion direction so that it could follow from the orthogonal direction, and the open / close door stood up to block the ball entrance Within the range of rotation from the position to the front side where the ball entrance is opened, the D-cut surface for the insertion port prevents the rotation shaft inserted through the bearing portion from unnecessarily coming out of the insertion port. Direction is set. In this way, since the pivot shaft of the door can be directly inserted and attached to the bearing portion provided on the front side of the case body, a conventional shaft support plate becomes unnecessary, and troublesome work is required in the assembly of the winning device. This can be omitted, and not only the workability in assembling is improved, but also the effect that the number of parts can be reduced and the manufacturing cost can be reduced.

In the present invention, a case where it is applied to a pachinko gaming machine will be described. First, a pachinko gaming machine in which the winning device according to the present invention is used will be described.

  FIG. 10 is a front view of a pachinko gaming machine in which the winning device according to the present invention is used. This is a third type of pachinko machine called a so-called right property. In the pachinko gaming machine P, an inner frame 101 is attached to an outer frame 100 having a vertically long rectangular shape so as to be freely opened and closed, and a game board 102 facing the front side is disposed on the inner frame 101. In addition, a transparent plate holding frame 103 that covers the front surface of the game board 102 is attached to the upper front portion of the inner frame 101 so as to be freely opened and closed. A front plate 104 is attached to the lower part of the front surface of the inner frame 101 and below the transparent plate holding frame 103. Pachinko balls as game balls are stored on the front surface of the front plate 104, and the pachinko balls are shot one by one. An upper ball tray 105 to be supplied to a section (not shown) is mounted. Further, a lower front plate 106 is mounted on the front surface of the inner frame 101 below the inner frame 101, and a lower ball plate 107 that stores pachinko balls overflowing from the upper ball plate 105 is mounted on the front surface of the lower front plate 106. ing. A hitting force adjusting handle 108 for adjusting the hitting force of a pachinko ball launched from the hitting ball launching unit to the front of the game board 102 is attached to one side of the lower ball tray 107 and in front of the lower front plate 106. Has been.

  An inner guide rail 109 and an outer guide rail 110, which are guide rails, are laid in a substantially spiral shape on the front surface of the game board 102, and are surrounded by the inner and outer guide rails 109 and 110. A game part 111 is formed. The game unit 111 is provided with a variable display device 113 having a variable display 112 that displays a variable pattern of characters, numbers, and the like at the center position thereof, and below the variable display 112 by winning a pachinko ball. A start winning opening 114 for changing the symbol displayed on the left is disposed, and a variable winning opening 116 having a pair of movable blade pieces 115 and 115 is disposed below the start winning opening 114.

  In addition, a rotating body 117 is arranged on the right side of the gaming unit 111 when viewed from the front. The rotating body 117 is composed of a rotating member 117b surrounded by an annular frame 117a whose upper end is opened and rotating in a plane parallel to the surface of the game board 102, and one pachinko ball is placed on the outer peripheral surface of the rotating member 117b. A ball receiving recess 118 that can be received is provided in a recessed manner, and a pachinko ball that has entered the ball receiving recess 118 is conveyed downward by a rotating member 117b and is taken in and electrically detected. Then, a winning device 119 according to the present invention is arranged below the rotating body 117, and when the pachinko ball entered into the ball receiving recess 118 is electrically detected, the winning device 119 is opened so that the pachinko ball can be won. It has become. A normal winning opening 120 is arranged on the left side of the game unit 111 when viewed from the front.

  Therefore, for example, when a pachinko ball wins the start winning opening 114, symbols such as characters and numbers on the variable display 112 start to change, and stop after a certain period of time. When the symbols at the time of the stop are aligned with specific symbols such as “333” and “777”, a big hit is made, and the pair of movable blade pieces 115 and 115 at the lower variable winning opening 116 are predetermined in a reverse C shape. Open for a time, eg 5 seconds. If a pachinko ball wins the variable winning opening 116 during this time, the right to win the jackpot is determined, and the player moves the pachinko ball to the right side of the game unit 111 and drives it. Along with this, when a pachinko ball enters the ball receiving recess 118 of the rotating body 117, it is transported downward along with the rotation of the rotating member 117b and is electrically detected. When the pachinko ball is detected, the winning device 119 below it opens to generate many winning balls at once. The winning device 119 is closed after a predetermined time has elapsed or when a predetermined number of pachinko balls have won, and each time the pachinko ball carried into the ball receiving recess 118 of the rotating body 117 is electrically detected, the winning device 119 operates as described above. repeat. This operation is performed up to 15 times, for example. In this way, the player can obtain many prize balls at a time.

  Next, the winning device 119 according to the present invention will be described. 1 is a perspective view of a winning device according to the present invention, FIG. 2 is an exploded perspective view thereof, FIG. 3 is a front view thereof, FIG. 4 is an enlarged cross-sectional view taken along line AA in FIG. FIG. 6 is an enlarged side sectional view of the winning device showing the operation of the solenoid. The winning device 119 has a mounting board 1 attached to the front surface of the game board 102 with screws, and a laterally long rectangular ball entrance 2 is opened on the mounting board 1. In addition, a case body 3 for processing a pachinko ball won in the ball entrance 2 is disposed on the rear surface of the mounting substrate 1. The case body 3 is formed of a transparent synthetic resin material, and the front surface has an opening 4 and is screwed to the rear surface of the mounting substrate 1 so as to surround the ball inlet 2, and is integrated with the mounting substrate 1. As a result, the ball inlet 2 and the opening 4 are in communication with each other.

  The case body 3 is divided into upper and lower parts, and a boss 6 having a screw hole 5 is provided at a substantially central part of the lower case body part 3a so as to project from the central part of the upper case body part 3b. A screw insertion hole 7 is opened at a position corresponding to. Then, the upper case body 3b is overlapped on the upper surface of the lower case body 3a, and the screw 8 is screwed into the screw hole 5 via the screw insertion hole 7, whereby the upper and lower case bodies 3a, 3b are assembled together. It is done. An opening / closing door 9 that opens and closes the ball entrance 2 by rotating up and down in the front-rear direction is disposed in the opening 4. The opening / closing door 9 will be described in detail later.

  The inside of the case body 3 is divided into right and left when viewed from the opening 4 side. Further, an inclined bottom plate 10 is provided on the right side that is continuous with the opening 4 on the front surface and is inclined downward, and a ball drop for discharging the pachinko ball that has rolled the upper surface of the inclined bottom plate 10 backward is provided at the lower end of the bottom plate 10. A mouth 11 is formed. On the upper surface of the ball outlet 11, a ball detector 12 having a ball passage 12 a communicating with the ball outlet 11 provided on the front side is disposed. As shown in FIG. 4, the sphere detector 12 is inclined about 30 degrees with respect to the horizontal plane so as to incline downward toward the front side, that is, the inclined bottom plate 10. The lower case body 3 a is integrally provided with a locking piece 13 having elasticity along one side of the ball detector 12, and faces the front end of the locking piece 13 toward the rear end of the ball detector 12. The engaging claw portion 13a is projected.

  As described above, the sphere detector 12 is disposed so as to be inclined downwardly. For example, if the sphere detector 12 is disposed substantially horizontally, an upright wall is inevitably provided on the rear side of the sphere opening 12a. A pachinko ball that is provided and bounces off against the standing wall is dropped to the ball opening 12a and discharged. For this reason, it takes extra time for the pachinko ball that won the ball entrance 2 to bounce off the ball drop opening 11 after passing through the ball passage 12a, and the pachinko ball discharge processing capacity is low. Therefore, the ball detector 12 is tilted downward to the front side, that is, the inclined bottom plate 10 side, so that the pachinko ball won at the ball inlet 2 is dropped directly onto the ball passage 12a of the ball detector 12. As a result, the time required for the pachinko ball to be discharged after winning at the ball entrance 2 can be shortened, and the discharge processing capacity of the pachinko ball won at the winning device 119 can be enhanced. The winning device 119 having such a configuration is suitable for a pachinko gaming machine in which many winning balls are generated at one time. In addition, the winning device 119 can be reduced in size.

  On the other hand, a storage chamber 14 is formed on the left side when viewed from the opening 4 side in the case body 3 and is held horizontally in the storage chamber 14, and the plunger 15 a is moved forward and backward, that is, toward the ball inlet 2 side. A solenoid 15 is disposed as a moving electric actuator. When the solenoid 15 is demagnetized, when the solenoid 15 is demagnetized, the plunger 15a advances to the front side when the solenoid 15 is demagnetized. Thus, the plunger 15a is retracted rearward. A pair of annular side plates 17 and 17 are provided at the front end of the plunger 15a at a predetermined interval in the front and rear direction.

  A connecting member 18 is provided between the tip of the plunger 15a and one side of the opening / closing door 9 corresponding thereto. The connecting member 18 has a planar U-shaped base frame 19 whose rear side is opened, and a bifurcated portion 20 that is divided into upper and lower portions is provided on the front surface of the base frame 19. Between the rear end portions of the U-shaped base frame 19, a horizontal rod 21 is passed, and shaft rods 22 project from both outer side surfaces of the rear end portion. Therefore, both shaft rods 22 and 22 are fitted into bearing recesses 23 and 23 provided in the lower case body 3a from above so that the bifurcated portion 20 faces the front side, and further, both annular side plates 17 at the tip of the plunger 15a are fitted. 17, the recumbent rib 21 provided between the rear ends of the connecting member 18 is interposed. Therefore, when the solenoid 15 is excited and the plunger 15a is retracted rearward, as shown in FIG. 5, the connecting member 18 is rotated rearward and the bifurcated portion 20 is rotated upward. On the other hand, when the solenoid 15 is demagnetized and the plunger 15a is advanced to the front side, the connecting member 18 is rotated to the front side and the bifurcated portion 20 is rotated downward as shown in FIG. It has become. The bifurcated portion 20 is engaged with an engagement pin 26 which will be described later provided on one side of the open / close door 9.

  The open / close door 9 is formed in a horizontally long rectangular shape that matches the ball entrance 2, and pivot shafts 24, 24 project from the both ends of the lower side along the lower side. Similarly, side plates 25, 25 projecting rearward from the left and right side edges, which are both ends of the lower side portion, are projected, and one side plate 25, that is, the outer surface of the side plate 25 located on the same side as the solenoid 15, An engagement pin 26 that engages with the bifurcated portion 20 is projected. The lower edge portion of the opening 4 is provided with bearing portions 27 and 27 for axially attaching the opening / closing door 9 on both sides thereof in a front view.

  The rotary shafts 24 and 24 at both ends of the opening / closing door 9 are both cylindrical, and a D-cut surface 28 obtained by cutting a part of the peripheral surface into a plane along the axial direction is formed on the rotary shafts 24 and 24. Is formed. At this time, for example, the length of the D-cut surface 28 to the opposite outer peripheral surface farthest from the D-cut surface 28 is set in a range longer than the radius of the rotating shaft 24 and shorter than the diameter. Has been.

  The two bearing portions 27, 27 on the front surface of the case body 3 have shaft holes 29, 29 parallel to the lower front side of the case body 3, and the shaft holes 29, 29 face slightly upward toward the front surfaces of the two bearing portions 27, 27. 29 and 30 are opened in parallel. As shown in FIG. 7, the distance L between the insertion ports 30 and 30 in the plane orthogonal to the center line of the shaft holes 29 and 29 is the farthest distance from the D-cut surface 28 of the rotating shaft 24. It is set a little longer than the dimension up to the outer peripheral surface. Accordingly, the opening / closing door 9 is arranged in front of the opening 4 of the case body 3 so that the bearings 27 and 27 can follow each other from the direction orthogonal to the central axis of the bearings 27 and 27, and D The rotation shafts 24, 24 are allowed to be inserted such that the cut surface 28 is substantially parallel to the insertion direction. Therefore, when the interval L in the surface orthogonal to the center line of the shaft hole 29 of each insertion port 30 is shorter than the dimension to the outer peripheral surface on the opposite side farthest from the D-cut surface 28 of each rotation shaft 24, Each rotating shaft 24 cannot be inserted into each insertion port 30.

  The direction of the D-cut surface 28 of each rotary shaft 24 with respect to each insertion port 30 is from the position where the open / close door 9 stands and blocks the ball inlet 2 to the position where the ball inlet 2 is opened by tilting forward. Within the rotation range, each rotation shaft 24 is determined so as not to be unnecessarily removed from each bearing portion 27. For example, when the open / close door 9 is raised, the rear surface of the open / close door 9 comes into contact with the front surface of the upper edge of the opening 4 of the case body 3 as shown in FIG. The D-cut surface 28 faces slightly upward with respect to the opening surface F of the insertion port 30. Further, in the state where the opening / closing door 9 is tilted to the front side, as shown in FIG. 9, the stop portion 31 provided at the rear end portion of one side plate 25 of the opening / closing door 9 is on the upper edge of the rear surface of the opening 4 in the case body 3. It contacts, and the rotation operation of the door 9 is regulated. The D-cut surface 28 faces slightly downward with respect to the opening surface F of the insertion port 30. Thus, in the range in which the open / close door 9 rotates from the standing position to the tilted position, the two rotation shafts 24, 24 do not unnecessarily come out of the insertion ports 30, 30 of the bearing portions 27, 27. A wiring board 33 is attached to the lower surface of the lower case body 3a by screws 32. A plurality of LEDs 34 are provided on the upper surface of the wiring board 33 so as to illuminate the case body 3 from below. Thereby, the illumination effect is enhanced.

  The gaming machine winning device 119 according to the present invention has the above-described configuration, and an assembly procedure thereof will be described. First, the solenoid 15 having the connecting member 18 attached to the tip of the plunger 15a is disposed in the storage chamber 14 in the lower case body 3a with the upper case body 3b removed. The shaft rods 22 and 22 of the connecting member 18 are fitted into the bearing recesses 23 and 23. Further, the ball detector 12 is disposed in correspondence with the ball drop opening 11, and the claw portion 13 a of the locking piece 13 is engaged with the rear end surface of the ball detector 12. Further, the wiring board 33 is attached by screwing the screw 32 to the lower surface of the lower case body 3a.

  And while opening / closing door 9 is arrange | positioned in the front surface of opening 4, as shown in FIG. 7, in the state which rotated 90 degrees or more to the front side from the standing state, it tilted through each insertion port 30. Each rotation shaft 24 is inserted into the shaft hole 29 of each bearing portion 27. That is, in this inserted state, the rotation shaft 24 has the D-cut surface 28 parallel to the insertion direction with respect to the interval L of the insertion port 30 so that each rotation shaft 24 can be easily inserted into each shaft hole 29. It has become. Accordingly, the opening / closing door 9 is arranged in front of the opening 4 of the case body 3 so that the shaft hole 29 of each bearing portion 27 is made to follow the direction orthogonal to the central axis of each shaft hole 29, and D The rotating shafts 24 can be inserted with the cut surface 28 being substantially parallel to the insertion direction.

  In a state where each rotation shaft 24 is inserted into the shaft hole 29 of each bearing portion 27, the D-cut surface 28 of the rotation shaft 24 is substantially orthogonal to the opening surface F of the insertion port 30 of each bearing portion 27. It has become. Therefore, in this state, the rotating shaft 24 can be easily extracted from the shaft hole 29 through the insertion port 30. Next, FIG. 8 shows a state in which the opening / closing door 9 is pivoted rearward around the pivot shafts 24 and 24 from the state in which the respective pivot shafts 24 are inserted into the shaft holes 29 of the respective bearing portions 27, and is shown in FIG. Thus, the D-cut surface 28 of the rotating shaft 24 faces the opening surface F of the insertion port 30 in the bearing portion 27 and is in a state of facing slightly upward. In this state, since the diameter of the rotation shaft 24 is longer than the interval L between the insertion ports 30, each rotation shaft 24 cannot be extracted from each shaft hole 29 via the insertion port 30.

  Further, in a state where the opening / closing door 9 is rotated forward about the rotation shafts 24 and 24 and the stop portion 31 is tilted in contact with the upper edge of the rear surface of the opening 4 in the case body 3, as shown in FIG. The D-cut surface 28 of the rotating shaft 24 faces the opening surface F of the insertion port 30 of the bearing portion 27 and is slightly downward. Even in this state, since the diameter of the rotation shaft 24 is longer than the interval L between the insertion ports 30, each rotation shaft 24 cannot be extracted from each shaft hole 29 via the insertion port 30. That is, in the range from the position where the open / close door 9 stands up to the tilted position where the open / close door 9 can be rotated to receive the pachinko ball, the rotary shaft 24 of the open / close door 9 comes out of the shaft hole 29 of each bearing portion 27. The positional relationship between the D-cut surface 28 and the insertion port 30 is determined so as not to be present.

  The attachment procedure of the solenoid 15, the connecting member 18, the ball detector 12, and the open / close door 9 is not limited to the order described above, and the order may be changed as long as the assembly is possible.

  As described above, in the present invention, the opening / closing door 9 is attached only by inserting each rotary shaft 24 from the front side of the lower case body portion 3 a in the case body 3 into the shaft hole 29 of each bearing portion 27. With the open / close door 9 raised, the ball detector 12 is disposed at a predetermined position on the rear side of the inclined bottom surface 10, and the rear end is locked to the claw portion 13 a of the locking piece 13. In this state, the case body 3 is assembled by superimposing the upper case body portion 3b on the upper surface of the lower case body portion 3a from above and screwing the screw 8 into the screw hole 5 via the screw insertion hole 7. Further, the mounting substrate 1 is fixed to the front surface of the case body 3 with screws. Thereby, the ball entrance 2 and the opening 4 are matched and communicated, and the winning device 119 is assembled. If this assembling method is adopted, it is expected that this kind of prize-winning device that has been assembled manually is automatically assembled by the machine.

  Although the present invention has been described with respect to a winning device that is a right-handed pachinko gaming machine and disposed below the right rotating body in front view on the gaming board surface, the present invention is not limited thereto. The present invention can be applied to any winning device that has an open / close door that opens and closes a ball entrance by being mounted on a game board surface of a pachinko machine regardless of whether it is a right item or not.
