[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a winning device for a pachinko machine in which an opening / closing door is forcibly opened by unauthorized means so that an illegal act of intentionally obtaining many winning balls can be completely prevented. .
[0002]
[Prior art]
Conventionally, a variable display device in which a plurality of symbols and numbers fluctuate on the game board surface, a start winning opening that fluctuates the plurality of symbols and numbers when a hitting ball wins, and the symbols and numbers are in a specific combination when stopped There is a pachinko machine equipped with a winning device that can generate a lot of winning balls at once when a right as a “big hit” is generated.
[0003]
For example, as shown in FIG. 10, the winning device has a horizontally long ball entrance 101 on a mounting board 100 which is attached in contact with the game board surface, and the center of gravity so that the ball entrance 101 always rotates forward. An opening / closing door 102 that is freely rotated in the front-rear direction is mounted. On the other hand, a solenoid 104 having a plunger 103 that moves forward and backward is disposed on one side of the mounting substrate 100, and a working rod 106 that is pivotally supported at the rear end of the plunger 103 and rotated in a vertical plane is provided. Has been attached. Further, the front end of the working rod 106 is engaged from above with an engagement piece 107 protruding rearward from one side of the back surface of the door 102. When the solenoid 104 is demagnetized, the plunger 103 moves forward by the urging of the spring 108 wound around the solenoid 104 to rotate the working rod 106 downward and push down the engagement piece 107 by its front end. The open / close door 102 is rotated rearward to be in a closed state unfavorable to the player. Further, when the solenoid 104 is energized, the plunger 103 moves backward against the bias of the spring 108, and accordingly, the action rod 106 is rotated upward and the opening / closing door 102 is rotated forward so that the player In an open state advantageous to the above.
[0004]
By the way, the open / close door 102 is held in its closed state only by the elastic force of the spring 108 wound around the plunger 103, and has no other interlocking lock mechanism. Accordingly, the plunger 103 is reversely moved against the urging force of the spring 108 through the action rod 106 when it is opened. For this reason, for example, during a game, let the player sprinkle a thin piano wire, etc. through the gap of the glass door frame, etc. on the game board surface, forcibly open the open / close door of the winning device, and deliberately obtain many winning balls In some cases, cheating was conducted.
[0005]
[Problems to be solved by the invention]
The present inventor attaches a connecting member to the distal end of the plunger and links them between the connecting member and the open / close door so that the above-described unauthorized acts are prevented, and only the forward / backward movement of the plunger is performed. For example, a pachinko hall clerk will open the glass door frame properly to open the door as needed for the sake of convenience. First, a pachinko machine winning device having an insertion hole through which an operation rod for operating the plunger from the front surface of the mounting substrate can be inserted through the connecting member at a position facing the connecting member. Invented and applied for a patent.
[0006]
However, when the insertion hole through which the operation rod for operating the plunger from the front surface of the mounting board is provided in this way, the store clerk of the pachinko hall properly opens the glass door frame as necessary. It is convenient when trying to open the door, but conversely, a piano wire drawn on the surface of the game board is inserted into this insertion hole, and the plunger is operated to forcibly open the door to intentionally open many winning balls. There was a problem that should be improved, such as allowing for fraudulent attempts to gain.
Accordingly, the present invention has been made to solve the above problems, and is provided with a shutter plate that is slid in the left-right direction and is always urged in the closing direction and can be opened by an operating rod. It is an object of the present invention to provide a winning device for a pachinko machine that can prevent fraudulent acts from occurring.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, a winning device for a pachinko machine according to the present invention is provided with a ball entrance on a mounting board and is freely rotated in the front-rear direction to the ball entrance to a closed state disadvantageous to the player. In the winning device, an opening / closing door for converting to an advantageous open state is mounted, and a solenoid that rotates the opening / closing door in the front-rear direction by moving the plunger forward / backward is provided on the back side of the mounting board. A linkage lock mechanism is provided between the tip and the open / close door, and the linkage lock mechanism is configured to be able to rotate the open / close door only by the forward / backward movement of the plunger, and the plunger is attached to the front surface. An insertion hole through which an operation rod for operating from the front side of the board can be inserted is opened. The insertion hole slides in the left-right direction and is constantly biased in the closing direction and can be opened by the operation rod. The constitution equipped with over plate.
[0008]
Therefore, even if a player tries to forcefully open the open / close door of the winning device by inserting a piano wire or the like through the gap in the glass door frame and inserting it through the insertion hole on the front during the game. Since the insertion hole is closed by the shutter plate, the plunger cannot be operated from the insertion hole, thereby preventing the opening / closing door from being unnecessarily opened and preventing illegal acts. In addition, when a pachinko hall clerk attempts to open the door by opening the glass door frame legitimately as necessary, open the shutter plate with the operating rod and insert the operating rod into the insertion hole. Then, the solenoid is operated, the linkage lock mechanism is released, the opening / closing door is rotated forward, and the ball entrance is opened, so that a legitimate act by the store clerk such as checking the winning device can be performed.
[0009]
Specifically, for example, an opening / closing door that is provided with a ball entrance on the mounting board and that freely rotates in the front-rear direction at the ball entrance to convert between a closed state that is disadvantageous to the player and an open state that is advantageous to the player. A winning device that is mounted and has a solenoid that pivots the door in the front-rear direction by moving the plunger back and forth on the back side of the mounting board, so that the solenoid moves the plunger back and forth in the front-rear direction. Arranged at right angles to the mounting board, a connecting member is attached to the tip of the plunger, and an interlocking lock mechanism is provided between the connecting member and the open / close door, and the interlocking lock mechanism is operated to advance and retract the plunger. And an operating rod for operating the plunger from the front side of the mounting substrate via the connecting member at a position on the front surface facing the connecting member. It opened may through insertion holes, the difference Komiana structure fitted with a shutter plate which can open is taken by biased always closing direction slides in the lateral direction and the operating rod.

Thus, a start winning opening 7 for changing each symbol / number on the display unit 6a is attached. Furthermore, when the symbols / numbers, etc. stop below it and the combination becomes a specific combination (for example, “7, 7, 7”), it becomes a special gaming state, and at a time under certain conditions. A large winning device 8 capable of generating many winning balls is mounted.
[0011]
As shown in FIGS. 2 and 3, the winning device 8 has an attachment board 9 attached to the front surface of the game board 2, and a horizontally long ball entrance 10 is formed at the center of the attachment board 9. Also, general winning holes 11 and 11 are provided on the front surface of the mounting substrate 9 on both sides of the ball entrance 10, and a frame whose rear surface is open on the back surface of the mounting substrate 9 so as to surround both sides of the ball entrance 10. The body 12 is integrally formed. Reference numeral 13 denotes an inner box frame that fits into the frame body 12 and is attached to the back side of the mounting substrate 9 by a plurality of screws and has front and rear end faces that are opened and closed. The open / close door opens and closes the ball inlet 10 on the front surface of the inner box frame 13. 14 is disposed.
[0012]
Angle restricting pieces 15 and 15 that are bent at right angles to the rear side are provided on both side edges of the open / close door 14, and a shaft operating rod 16 protrudes from an outer front portion of each angle restricting piece 15. The angle restricting piece 15 (on the right side in FIG. 3) is provided with an engaging protrusion 17 at the outer lower portion. Reference numerals 18 and 18 denote shaft support plates which are attached to both sides of the front surface of the inner box frame 13 by screws, and the opening / closing door 14 is formed by inserting the shaft operating rods 16 and 16 into shaft holes 19 and 19 provided on the inner edges, respectively. It can be freely rotated in the front-rear direction. In addition, a ball receiving plate 20 is disposed at the bottom of the inner box frame 13, and the ball receiving plate 20 is inclined rearward so that it is substantially flush with the open / close door 14 when rotated forward.
[0013]
Reference numeral 21 denotes a rear box frame joined to the rear surface of the middle box frame 13, and an intake port 24 into which a hit ball that rolls the ball receiving plate 20 enters is provided at the center. The general winning opening 25a and the V winning opening 25b are arranged on the right and left. Further, a horizontal shaft 30 is provided on the front surface of the rear box frame 21 through a shaft hole 26 to project forward from an attachment frame 28, which will be described later, at an intermediate position between the two winning openings 25a and 25b. A distribution lever 27 is provided that distributes the hit balls from 13 to the general winning opening 25a or the V winning opening 25b.
[0014]
Reference numeral 28 denotes a mounting frame joined to the rear surface of the rear box frame 21. The mounting frame 28 partially protrudes from the front surface of the front contact plate 28a on the left and right sides of the lower box frame, and is interposed in the general winning port 25a and the V winning port 25b. The ball detectors 29 and 29 for counting the winning balls are disposed, and a horizontal shaft 30 that protrudes forward from the contact plate 28a at an intermediate position and on which the distribution lever 27 is rotatably supported is provided. Is provided. A first solenoid 31 for operating the sorting lever 27 and a second solenoid 32 for operating the open / close door 14 are disposed on the back side of the contact plate 28a. In addition, although illustration is abbreviate | omitted, all the said inner box frame 13, the rear box frame 21, and the attachment frame 28 are joined by screwing.
[0015]
The first solenoid 31 is disposed laterally, that is, in the left-right direction. An interlocking member 34a is attached to the tip of the plunger 33, and an interlocking member 34b is attached to the rear end of the horizontal shaft 30, and these interlocking members 34a, 34b. When the plungers 33 are engaged with each other, the horizontal shaft 30 rotates forward and backward as the plunger 33 moves forward and backward. Therefore, when the first solenoid 31 is demagnetized, the plunger 33 is urged toward one side by the spring 35 wound around the plunger 33 and thereby the sorting lever 27 is moved toward one side. The general winning opening 25a is rotated and held at a position where the V winning opening 25b is closed.
[0016]
On the other hand, when the first solenoid 31 is energized in this state, the plunger 33 moves backward against the bias of the spring 35, whereby the horizontal shaft 30 is rotated in the opposite direction to the above, and the distribution lever 27 is generally moved. The winning opening 25a is closed and held at a position where the V winning opening 25b is opened. For example, the door 14 opens when a special gaming state such as a big hit occurs during the game. At this time, the first solenoid 31 is excited to close the general winning opening 25a and open the V winning opening 25b. As a result, the hit ball that has entered the inner box frame 13 via the ball entrance 10 rolls on the upper surface of the ball receiving plate 20 and wins the V winning opening 25b. At this time, as soon as one hit ball wins the V winning opening 25b, the first solenoid 31 is immediately demagnetized and the sorting lever 27 is rotated again in the reverse direction to open the original general winning opening 25a and open the V winning opening 25b. Return to the close position. Then, all the remaining hit balls are awarded to the general winning opening 25a, and when the predetermined number of hit balls win the general winning opening 25a, or when a predetermined time elapses, the opening / closing door 14 is rotated backward to close the ball entrance 10. Thereafter, the same operation is repeated a predetermined number of times under a certain condition so that many winning balls are generated at one time. As described above, the reason why only one hit ball is won in the V winning opening 25b is that there is a rule that the winning probability can be suppressed to approximately one third or less.
[0017]
The second solenoid 32 is disposed on the inner side of the metal surrounding frame 36 that surrounds the back side of the mounting frame 28, and is disposed vertically, that is, perpendicularly to the mounting substrate 9. Then, the connecting member 38 is attached to the tip of the plunger 37 that moves back and forth in the front-rear direction. The connecting member 38 is formed in an L-shaped side surface, and a vertical plate portion 38b is provided on the lower surface of the horizontal plate portion 38a, and a vertical groove 39 opened at the lower end is provided in the vertical plate portion 38b. The connecting member 38 is formed on one side of the middle box frame 13 through an opening groove 40 formed on one side of the rear box frame 21, and faces the side frame portion 41 having both front and rear ends opened.
[0018]
Reference numeral 42 denotes a linkage lock mechanism that links the connecting member 38 and the opening / closing door 14 with each other and rotates the opening / closing door 14 only by the forward / backward movement of the plunger 37. And a door crank piece 43 that rotates the opening / closing door 14 and a door lock piece 44 that prevents unnecessary opening operation of the opening / closing door 14. On the other hand, a support rod 46 is horizontally mounted between the bearing portions 45 provided on both sides of the opening groove 40 on the front surface of the rear box frame 21, and the door crank pieces 43 and the door lock pieces 44 are respectively locked to the door locks. The piece 44 is axially supported so as to be located inside.
[0019]
The door crank piece 43 is formed into a side inverted L-shape, a shaft hole 47 through which the support rod 46 is inserted is provided at the rear end portion, and a shaft cylinder 47 a that communicates with the shaft hole 47 is provided on the inner side surface. . A first protrusion 48 that engages with the vertical groove 39 of the connecting member 38 is provided on the inner surface of the tip of the upward piece 43a that extends upward, and at the tip of the forward piece 43b that extends forward, the open / close door 14 is provided. A bifurcated engagement portion 49 that engages with the engagement protrusion 17 is provided. On the other hand, the door lock piece 44 is formed in a substantially triangular shape on the side surface, and a shaft hole 50 into which the shaft tube 47a is fitted is projected at the rear end portion. Further, a second projection 51 is provided on the inner side of the upper end portion, which is located below the first projection 48 and engages with the longitudinal groove 39. The second projection 51 pivots rearward on the lower surface of the front end portion to close the ball inlet 10. A notch recess 52 that can be engaged with the engaging protrusion 17 of the open / close door 14 from above is provided. The notch recess 52 and the bifurcated engagement portion 49 are substantially at the same position from the support rod 46. As a result, as shown in FIG. 4, the connecting member 38 at the tip of the plunger 37 and the open / close door 14 are linked by the linkage lock mechanism 42. A plurality of support rods 53 project from the back surface of the contact plate 28 a of the mounting frame 28, and a wiring board 54 is attached to the support rods 53.
[0020]
Thus, in the present invention, as shown in FIGS. 7 and 9A, the insertion hole 56 is opened on the front surface of the mounting substrate 9 and opposed to the front end surface of the horizontal plate portion 38a of the connecting member 38. ing. As will be described later, the insertion hole 56 is a case where a pachinko hall clerk attempts to open the ball entrance 10 by opening the glass door frame 3 properly and rotating the opening / closing door 14 forward as necessary. The operation rod 62 is inserted to push the connecting member 38 and the plunger 37 is forcibly retracted to rotate the door 14. A shutter plate 57 formed in a plane L shape is attached to the insertion hole 56. On the other hand, in the vicinity of the insertion hole 56 and on the back surface of the mounting substrate 9, a guide frame 58 is disposed in a frame portion 41 a provided on the upper side of the side frame portion 41, and a vertical piece of the shutter plate 57. 57a is accommodated in the frame part 41a, and the horizontal piece 57b protrudes through a vertical groove 59 formed on the insertion hole 56 side of the frame part 41a, and slides in the left-right direction to thereby form the insertion hole 56. It can be opened and closed. Further, a compression spring 60 is interposed between the vertical piece 57a and the guide frame 58 in the frame portion 41a, and always urges the shutter plate 57 in a direction to close the insertion hole 56. Further, a hooking portion 61 is provided on the front surface of the horizontal piece 57b so that the tip of the operating rod 62 is caught when the shutter plate 57 is opened and the opening operation is easy.
[0021]
Therefore, first, when the game is not in a special game state, the second solenoid 32 is demagnetized and the plunger 37 is moved forward by the bias of the spring 55 as shown in FIG. The door crank piece 43 and the door lock piece 44 are both turned counterclockwise in the figure, and the engagement protrusion 17 is pushed down by the bifurcated engagement portion 49 to turn the open / close door 14 backward to enter the ball entrance. 10 is closed. At this time, the notch recess 52 of the door lock piece 44 is engaged with the engagement protrusion 17 from above.
[0022]
In this state, when the special gaming state is entered, the second solenoid 32 is excited as shown in FIG. 5B, and the plunger 37 begins to move back against the bias of the spring 55. The lock piece 44 rotates in the clockwise direction in FIG. However, because the second protrusion 51 is below the first protrusion 48, the door lock piece 44 rotates faster than the door crank piece 43, and thereby the bifurcated engagement portion 49 pushes up the engagement protrusion 17. The engagement with the notch recess 52 is released first.
[0023]
Then, the plunger 37 moves backward, and the engagement projection 17 is pushed up by the bifurcated engagement portion 49 of the door crank 43 as shown in FIG. 5C, and the open / close door 14 rotates counterclockwise, that is, forward. Then, the ball entrance 10 is opened, and a lot of hit balls can be received at once. Further, when the second solenoid 32 is demagnetized, the plunger 37 advances as shown in FIG. 5A by the bias of the spring 55, and the door crank piece 43 and the door lock piece 44 rotate counterclockwise to open and close. The door 14 is returned to the original closed state shown in FIG.
[0024]
Therefore, when a player puts a piano wire or the like on the two sides of the game board during a game and intentionally opens the door 14 to perform an illegal act, as shown in FIG. The center 02 of the flange 46 is at the same height position, and the distances 01 and 03 between the center 01 of the shaft operating flange 16 and the center 03 of the engagement protrusion 17 and between the center 03 of the engagement protrusion 17 and the center 02 of the support flange 46. 6 is longer than the distance 01, 02 between the center 01 of the shaft operating rod 16 and the center 02 of the supporting rod 46 from the triangle theorem, so the door 14 is forcibly forced in the direction of the arrow in FIG. Even if the ball inlet 10 is rotated to be opened, the engaging projection 17 is locked while being engaged with the notch recess 52, and the opening / closing door 14 cannot be rotated. Thereby, the illegal act performed by opening the door 14 is prevented.
[0025]
In the present embodiment, the second solenoid 32 is disposed so as to be perpendicular to the mounting substrate 9 in the front-rear direction, but may be disposed in parallel in the up-down direction. Of course, the linkage lock mechanism 42 may have other configurations as long as it has a linkage lock mechanism in addition to the combination of the door crank piece 43 and the door lock piece 44.
[0026]
Next, it is necessary to open the opening / closing door 14 from the front side of the game board 2 for inspection at the time of inspection from the manufacturer at the time of shipment or at the time of failure occurring during the game in the pachinko hall. Alternatively, the store clerk opens the glass door frame 3, and the shutter plate 57 is opened against the urging force of the compression spring 60 by hooking the tip of the operating rod 62 to the hook 61 as shown in FIGS. Then, the front end surface of the horizontal plate portion 38a of the connecting member 38 is pushed. As a result, the plunger 37 moves backward against the bias of the spring 55, and the linkage lock mechanism 42 performs the same operation as in FIG. Further, when the operating rod 62 is pulled out, the plunger 37 moves forward by the bias of the spring 55, rotates the open / close door 14, and closes the ball inlet 10. In this way, the inspection can be performed.
[0027]
On the other hand, even if the player tries to insert a piano wire or the like on the surface of the game board 2 during the game and tries to insert the tip of the piano wire into the insertion hole 56, it is obstructed by the shutter plate 57 and cannot be inserted. Therefore, the open / close door 14 cannot be intentionally opened, and an illegal act is prevented.
[0028]
Furthermore, although illustration is omitted, when the general winning ports 11 and 11 are mounted on both sides of the ball inlet 10 of the mounting board 9 as in the present embodiment, the insertion holes 56 of the mounting board 9 are formed on the front surface thereof. An insertion hole that communicates in a straight line may be opened, and in this way, since the gap between the front face of the general winning opening 11 and the glass plate of the glass door frame 3 is usually very narrow, It becomes almost impossible to insert a piano wire into the insertion hole 56, which is more effective in preventing fraud.
[0029]
【The invention's effect】
As described above, the winning device for a pachinko machine according to the present invention is provided with the linkage lock mechanism that links the plunger tip and the opening / closing door, and the linkage lock mechanism is opened / closed only by the forward / backward movement of the plunger. And an insertion hole through which an operation rod for pushing the plunger from the front side of the mounting board can be inserted, and the insertion hole slides in the left-right direction. The shutter plate that is always urged in the closing direction and can be opened by the operation rod is installed, so when opening the opening / closing door for inspection or failure at the manufacturer or pachinko hall, open the shutter plate from the game board side The door can be opened easily by inserting the casket, and work for failure and inspection can be done quickly and easily, while the insertion hole is normally closed by the shutter plate. Because it is an effect that even cheating to be obtained many winning ball deliberately to open forcing door by inserting the tip of the piano wire is prevented.
