[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball game machine.
[0002]
[Prior art]
A conventional ball game machine has a prize ball discharge device that discharges a game ball when the game ball launched on the game board surface wins a prize opening, and an upper plate passage that guides the game ball discharged from the prize ball discharge device to the upper plate , A lower plate passage that guides the game balls discharged from the prize ball discharge device to the lower plate, a branch portion that is a branch portion between the upper plate passage and the lower plate passage, and a discharge port of the prize ball discharge device. The game ball that has flowed into the branch from the spill bag is usually led to the upper plate passage until the upper plate passage is filled with the game ball and becomes closed. When the passage was filled with game balls and became closed, it was guided to the dish passage.
[0003]
The reason why the upper plate passage is filled with game balls and becomes closed and the game balls are guided from the branching portion to the lower plate passage is because there are so many game balls discharged from the prize ball discharge device. In most cases, special games are held that open the mouth. Accordingly, the prize ball discharging device operates in a continuous manner, and game balls flow into the branch portion one after another.
That is, the number of inflows of game balls per unit time is increased, and it is necessary to quickly cause the game balls to flow out from the branch portion to the upper plate passage or the lower plate passage. For this purpose, the width of the upper plate passage and the lower plate passage may be widened.
[0004]
[Problems to be solved by the invention]
However, since the width of the lower plate passage is limited by the thickness of the mechanism plate, it has been necessary to increase the thickness of the mechanism plate in order to increase the width of the lower plate passage in the conventional mechanism plate.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the bullet ball game machine according to claim 1, having the above structure, the prize ball discharge device discharges the game ball when the game ball fired on the game board surface wins the prize opening. The upper plate path guides the game balls discharged from the prize ball discharge device to the upper plate, and the lower plate passage guides the game balls discharged from the prize ball discharge device to the lower plate. A branching portion, which is a branching portion between the upper plate passage and the lower plate passage, and the discharge port of the prize ball discharging device are connected and communicated with each other through an outflow gutter.
[0009]
The threshold plate separates the upper plate passage and the lower plate passage, and a space for a game ball to pass through is provided above the threshold plate. Further, there is provided an overhanging portion that protrudes from the back side of the ball game machine and is provided along the branching portion from the connecting portion with the outflow rod to the lower plate passage beyond the threshold plate. As for the height of the threshold plate, the height from the upper plate passage exceeds the radius of the game ball, and a step is provided between the projecting portion and the branch portion.
The game ball that has flowed into the branch from the spillway is prevented from proceeding to the lower plate passage by the threshold plate and the step until the upper plate passage is filled with the game ball and becomes closed, and is guided to the upper plate passage. When the upper plate passage is filled with the game ball and is in the closed state, it passes over the threshold plate, passes through the space, or goes over the step to enter the overhanging portion and is guided to the lower plate passage.
[0010]
Since the overhanging portion is provided at the branch portion, when the upper plate passage is blocked by the game ball, the passage width of the game ball at the branch portion is the same as that of the game ball closing the upper plate passage. An overhang is added to the upper part. For this reason, even if it does not enlarge the width | variety of lower tray channel | path itself, the game ball which flowed into the branch part can be quickly flowed out to a lower tray channel | path. Moreover, as the mechanism board, only the thickness increases at the overhanging portion, and it is not necessary to increase the thickness throughout.
[0011]
【Concrete example】
Next, a specific example of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic front view of a pachinko machine 10 as a ball game machine. As shown in FIG. 1, a liquid crystal display panel 14 is assembled at the center of the game board 12 installed in the pachinko machine 10. A start winning opening 18 is provided below the liquid crystal display panel 14, and a large winning opening 20 called an attacker and an out hole 21 are installed below the start winning opening 18. In addition to this, the game board 12 is provided with a windmill, a well-known ordinary prize opening, and the like (not shown). Further, the front side of the game board 12 is covered with a glass plate 22, and a game area 16 is formed between the game board 12 and the glass plate 22.
[0012]
On the front side of the pachinko machine 10, an upper plate 24 is provided below the game board 12, and a lower plate 26 is provided below the upper plate 24. The upper plate 24 and the lower plate 26 are capable of storing game balls, and serve as receiving balls for the game balls discharged by the pachinko machine 10 as prize balls. Further, the upper plate 24 communicates with a launching device (not shown), and a game ball supplied from the upper plate 24 can be launched toward the game area 16. In the lower front corner of the pachinko machine 10, a launch handle 28 for operating the launch device is installed, and the player can adjust the strength of the launch force by rotating the launch handle 28.
[0013]
As shown in FIG. 2, on the back side of the pachinko machine 10, a mechanism board 29 that holds the game board 12 and is assembled with various components is mounted. Further, on the back side of the game board 12, there are a symbol control device 31 for controlling the liquid crystal display board 14, a main control device 33 that controls the entire pachinko machine 10, a start winning port 18, a grand winning port 20, and the like. A safe ball cage (not shown) that collects the winning balls is installed.
[0014]
A prize ball tank 30 for storing game balls supplied for prize balls from a game ball supply facility (not shown) of the game hall is disposed at the top of the mechanism board 29. The bottom of the prize ball tank 30 is provided with an outlet (not shown) for allowing game balls to flow out, and a tank rail 32 is connected to the outlet for allowing the game balls flowing out therefrom to flow down while being aligned. Has been.
[0015]
An L-shaped basket 34 is connected to the downstream end of the tank rail 32, and the path of the game ball can be changed almost vertically here. A bowl-shaped heel 36 is connected to the lower end of the heel 34, and the lower end of the heel 36 is connected to a prize ball discharging device 38. The basket 36 plays a role of reducing the load of the game ball applied to the prize ball discharging device 38.
[0016]
An outflow rod 42 is connected to the discharge port 40 of the prize ball discharging device 38, and the lower end of the outflow rod 42 is communicated with the branch portion 44.
2, 3, and 4, the branch portion 44 is a portion that continues to the upper plate passage 46 that communicates with the upper plate 24 shown in FIG. 1, and the upper plate passage 46 and the lower plate 26 shown in FIG. 1. This is a branching portion with the lower dish passage 48 that leads to. As shown in FIG. 1, the upper dish passage 46 communicates with the upper dish 24 through an upper dish discharge port 47, and the lower dish passage 48 communicates with the lower dish 26 through a lower dish discharge port 49.
[0017]
The upper dish passage 46 and the lower dish passage 48 are separated by a threshold plate 50. As shown in FIG. 4, the threshold plate 50 stands up substantially perpendicular to the upper plate passage 46, and its height exceeds the radius of the game ball B. Further, a space K sufficient for the game ball B to pass through is secured above the threshold plate 50. For this reason, the game ball B that has flowed into the branch portion 44 from the outflow rod 42 is normally prevented from proceeding toward the lower plate passage 48 by the threshold plate 50 and is guided to the upper plate passage 46.
[0018]
As shown in FIGS. 2, 3, and 4, a projecting portion 52 is provided along the branch portion 44 from the connecting portion with the outflow ridge 42 to the lower plate passage 48 beyond the threshold plate 50. . As shown in FIGS. 3 and 5, the overhanging portion 52 projects toward the back side of the pachinko machine 10 with respect to the mechanism board 29. As shown in FIGS. 2 and 4, the bottom surface 54 of the overhanging portion 52 is inclined from the outflow trough 42 side to the lower dish passage 48 side.
[0019]
And as shown in FIG. 4, the level | step difference 56 of the height which the game ball B cannot get over is provided between the bottom face 54 and the branch part 44 (upper dish channel | path 46). For this reason, the game ball B that has flowed into the branch portion 44 from the outflow rod 42 does not normally enter the overhang portion 52.
[0020]
However, when a large amount of game balls are accumulated in the upper plate 24 and the game ball B is filled up to the upper plate passage 46 as shown in FIG. (V) passes over the game ball B (b) that fills the upper plate passage 46, so that part of the vehicle passes over the step 56 and enters the overhanging portion 52 (see FIGS. 3 and 4). Game ball B (w)), and reaches the lower plate passage 48 through the overhanging portion 52 (see game ball B (x) in FIGS. 3 and 4). At this time, there is also a game ball B (x) that passes over the game ball B (b) filling the upper plate passage 46 and reaches the lower plate passage 48 through the space K.
[0021]
As described above, the branching portion 44 exclusively guides the game ball B flowing in from the outflow rod 42 to the upper plate passage 46 until the upper plate passage 46 is filled with the game ball B and is in the closed state. When the ball is closed, the game ball B is advanced to the lower dish passage 48.
[0022]
Even the upper plate passage 46 is filled with the game balls B because the game balls B discharged from the prize ball discharge device 38 are very many. For example, a special game in which the special winning opening 20 is opened is performed. In most cases. Therefore, the prize ball discharge device 38 operates in a standing manner, and game balls flow into the branch portion 44 one after another.
[0023]
In other words, the number of inflows of game balls per unit time increases, and it is necessary to cause the game balls to quickly flow out from the branch portion 44 to the upper dish passage 46 or the lower dish passage 48. For this purpose, the width of the upper plate passage 46 and the lower plate passage 48 may be increased. However, since the width of the lower plate passage 48 is limited by the thickness of the mechanism plate 29, it is necessary to increase the thickness of the mechanism plate in the conventional mechanism plate in order to widen the width of the lower plate passage 48.
[0024]
However, in the mechanism board 29 of this specific example, since the projecting portion 52 is provided in the branching portion 44, when the upper plate passage 46 is closed with the game ball B as shown in FIG. The passage width of the game ball B in the branch portion 44 is obtained by adding the overhanging portion 52 to the upper side of the game ball B closing the upper dish passage 46. For this reason, even if the width of the lower dish passage 48 itself is not increased, the game ball B that has flowed into the branch portion 44 can be quickly discharged to the lower dish passage 48. In addition, the mechanism panel 29 only increases in thickness at the overhanging portion 52, and does not need to be increased throughout.
[0025]
As shown in FIG. 2, the mechanism board 29 is provided with a safe ball collecting unit 58 for collecting game balls from the safe ball cage, and the game balls collected in the safe ball collecting unit 58 are stored in the safe ball set. It is a structure that is discharged to the side of the accommodating portion 60 provided below the portion 58.
[0026]
The housing 60 is provided in the mechanism panel 29 as a box-shaped cavity, and a maintenance cover 62 serving as a lid thereof can be freely opened and closed.
As shown in FIG. 6, a full switch 64 is installed inside the accommodating portion 60. The rocking piece 66 of the full switch 64 is a metal elastic body, and can be rocked and displaced with the base 68 as a fulcrum. The switch protrusion 70 is reciprocally displaced according to the rocking displacement. When the switch protrusion 70 is in the protruding position as shown, the signal level of the full switch 64 is high, and when the switch protrusion 70 is pushed into the main body side of the full switch 64, the signal level of the full switch 64 is high. Becomes low level.
[0027]
A pushing member 74 is attached to the wall 48a of the lower dish passage 48 so as to be swingably supported by a shaft 72 fixed to the wall 48a. A coil spring 78 in a compressed state is interposed between the long side 76 of the inverted L-shaped pushing member 74 and the wall 48a, and urges the pushing member 74 in a direction away from the wall 48a. A short side 77 of the pushing member 74 passes through a hole 48 b provided in the wall 48 a, and the head 79 is brought into contact with the swing piece 66. Therefore, when the pushing member 74 is displaced toward the wall 48a against the biasing force of the coil spring 78, the swing piece 66 is displaced toward the main body side of the full switch 64 by the head 79, and the full switch 64 signal levels can be switched.
[0028]
In addition, a safe ball introduction rod 104 and a safe ball discharge device 106 that are in communication with the safe ball assembly unit 58 are installed in the housing unit 60.
The ball passage 108 of the safe ball discharge device 106 has a shape in which a cylindrical portion of an upper end portion 108a serving as an entrance and a lower end portion 108b serving as an exit side are connected by a side wall portion 108c on the safe ball introduction rod 104 side. A pair of opposed openings 110 and 112 are provided in the central portion of the side wall portion 108 c, and a safe ball switch 114 is installed over the openings 110 and 112. The safe ball switch 114 normally outputs a high level signal, but when the game ball B exists inside as shown in the figure, the signal level is changed to a low level.
[0029]
Also, in the ball passage 108, a swing member 120 comprising a pair of plate portions 116a, 116b pivotally supported by the upper end portion 108a and a ball receiving portion 118 provided at the tip of the plate portions 116a, 116b is installed. ing. The swing member 120 is driven by a solenoid 124 connected via a wedge member 122 and can swing in the ball passage 108. A spring 126 for returning the solenoid 124 is attached to the wedge member 122.
[0030]
With such a configuration, the game ball B guided from the safe ball introduction basket 104 to the safe ball discharge device 106 falls in the ball passage 108 and is temporarily stopped at the ball receiving unit 118. Here, the safe ball switch 114 detects the game ball B and changes the signal level to a low level.
[0031]
The output signal of the safe ball switch 114 is input to the main control unit 33 and used for counting the number of safe balls. This total is transmitted from the main control unit 33 to the hall computer (not shown) as part of the operation data of the pachinko machine 10.
Further, since the full switch 64 and the safe ball discharge device 106 are accommodated in the common accommodation portion 60, the accommodation space can be used effectively and the maintainability is excellent.
[0032]
Next, when the swing member 120 is swung in the direction of arrow B by the operation of the solenoid 124, the game ball B passes through a gap formed between the ball receiving portion 118 and the ball passage 108 and falls. When the game ball B falls, the signal level of the safe ball switch 114 returns to the high level. At this time, if there is a next game ball B, the game ball B is prevented from falling by the wedge member 122.
[0033]
Further, when the wedge member 122 moves backward with the return of the solenoid 124, the subsequent game ball B falls and stops on the ball receiving portion 118, and the safe ball switch 114 operates as described above. In this way, the winning game balls are discharged exactly one by one.
As shown in FIG. 2, a discharge basket 128 connected to a game ball collection basket on a game machine installation island (not shown) is provided below the storage unit 60. The discharge ball 128 is configured such that the game ball discharged from the safe ball discharge device 106 and the game ball from the out hole 21 (see FIG. 1) merge, and the merged game ball is discharged to the gaming machine installation island. The
[0034]
As shown in FIG. 2, an error correspondence table 130 and an error indicator 132 which is a 7-segment LED indicator are installed at the lower corner of the mechanism panel 29. As shown in FIG. 7, the error correspondence table 130 describes error codes 0 to 9 and the contents and countermeasures for the corresponding abnormalities.
[0035]
Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG.
The main controller 33 is configured as a microcomputer including a known CPU 80, RAM 82, ROM 84, input interface 86, output interface 88, and the like.
[0036]
The input interface 86 includes a start winning switch 90 for detecting a game ball won in the start winning port 18, a 10 count switch 92 for detecting a game ball won in the big winning port 20, A V switch 94, a full switch 64, a safe ball switch 114, and the like for detecting a game ball passing through a special area (not shown) are connected.
[0037]
Connected to the output interface 88 are a solenoid 96 for opening the special winning opening 20, an error indicator 132, a prize ball discharging device 38, a symbol control device 31, a launching device 98, and the like.
With such a configuration, the CPU 80 of the main control device 33 obtains signals and data input from the input interface 86 side, and uses these signals and data to the output interface 88 according to a program stored in the ROM 84. It is possible to send command signals to each connected unit and control their operations and the like.
[0038]
Several examples of the processing of the CPU 80 will be described.
First, the CPU 80 executes a lottery process and a special game process as control related to the game progress. In this process, when the CPU 80 knows the winning of the game ball to the start winning opening 18 based on the signal from the start winning switch 90, it determines by hitting by lottery. An instruction is given to the symbol control device 31 according to the determination result, and if it is a win, a special symbol indicating a win is displayed, and if it is off, a miss is displayed. Further, the CPU 80 executes a process related to a special game such as operating the solenoid 96 to open the special winning opening 20.
[0039]
In addition, the CPU 80 determines that the launching device 98 is not capable of paying out the prize ball, for example, when the prize ball tank 30 is empty or the lower plate 26 is filled with a game ball, so that the prize ball cannot be paid out. Operation may be restricted.
For example, as described above, when the upper plate 24 and the upper plate passage 46 are filled with the game balls and the state where the game ball as the prize ball is guided to the lower plate passage 48 continues, the lower plate 26 is also filled with the game balls. The game ball that can no longer flow out to the lower tray 26 stays in the lower tray passage 48. Then, the pushing member 74 is pressed against the wall 48a by the pressure of the game ball. Pushing by the head 79 of the pushing member 74 pressed against the wall 48 a, the swing piece 66 of the full switch 64 is swung and displaced, and the switch protrusion 70 is pushed into the main body side of the full switch 64. As a result, since the signal level of the full switch 64 changes, the CPU 80 can know that the lower plate passage 48 is filled with the game ball.
[0040]
In this way, when even the lower dish passage 48 is seen as a game ball, it is not preferable to operate the prize ball discharge device 38 (discharge the prize ball). Therefore, the CPU 80 stops the launch of the game ball into the game area 16, that is, the operation of the launch device 98, in order not to generate a prize that causes the prize ball to be discharged.
[0041]
In addition to the progress of the game, the CPU 80 also periodically performs a monitoring process as to whether or not the switches are operating normally. Next, in order to simplify the description, this process will be described by taking monitoring of the start winning switch 90, the 10 count switch 92, and the V switch 94 as an example.
[0042]
The CPU 80 executes the error display process shown in FIG. 9 every time a preset monitoring execution timing arrives. In this error display process, the CPU 80 determines the state of the start winning switch 90. Specifically, it is determined whether or not the signal level of the start winning switch 90 has been low for a predetermined time or more (step 210).
[0043]
Start winning switch 90 When the game ball is not detected, the signal level is high level, and the structure is switched to the low level only when the game ball is detected. (1) There is a game ball continuously at the position detected by the start winning switch 90 (= ball clogging), (2) failure of the starting winning switch 90, (3) disconnection of the line from the starting winning switch 90 Can be assumed. In any case, it is an abnormal state in which an accurate signal cannot be obtained from the start winning switch 90.
[0044]
Since the 10 count switch 92 and the V switch 94 operate in the same manner as the start winning switch 90, the determination of whether they are normal or abnormal is the same.
Therefore, when the signal level of the start winning switch 90 is low for a predetermined time or more, the CPU 80 determines that an abnormality has occurred and sets the abnormality flag F1 to 1 (step 220).
[0045]
Next, the CPU 80 determines the state of the 10-count switch 92 (step 230), and if abnormal, sets the abnormality flag F2 to 1 (step 240).
Further, the CPU 80 determines the state of the V switch 94 (step 250), and if it is abnormal, sets the abnormality flag F3 to 1 (step 260).
[0046]
Thereafter, the CPU 80 determines whether or not the big prize opening 20 is closed (step 270). If it is closed (step 270: YES), the CPU 80 determines whether or not the big prize opening 20 is opened immediately before it. It is determined whether or not there is a winning (step 280). If there is no winning (step 280: NO), the abnormality flag F4 is set to 1 (step 290).
[0047]
If the big prize opening 20 is opened and a game ball is normally fired, it is unlikely that the big prize opening 20 will not win. Therefore, the absence of the winning is very likely that there was some trouble such as the game ball not being normally fired. The processing in steps 270 to 290 is executed in order to check whether such trouble exists.
[0048]
Next, the CPU 80 determines the presence / absence of an error, specifically, whether any of the abnormality flags F1 to F4 is 1 (step 300). If the abnormality flags F1 to F4 are all 0, the CPU 80 displays 0 on the error indicator 132 (step 310), and temporarily ends the error display process.
[0049]
On the other hand, if any of the abnormality flags F1 to F4 is 1, the CPU 80 determines whether the plurality of abnormality flags F1 to F4 is 1, that is, whether there are a plurality of abnormal portions (step 320). If there is one abnormal location (step 320: NO), the CPU 80 causes the error display 132 to display a fixed number such as 1 corresponding to the abnormal flag F1 to F4 (step 330), and there are multiple abnormal locations. If (for example, F2 and F3 are 1) (step 320: YES), the CPU 80 causes the error indicator 132 to blink and display a number corresponding to the young number of the abnormality flag F1 to F4, for example, 2 (step 330). .
[0050]
Next, the CPU 80 waits for the cause of the abnormality to be resolved (step 350). Specifically, when the abnormality flags F1 to F3 are 1 (signal abnormality of the start winning switch 90, the 10 count switch 92, and the V switch 94), it waits for the signals of these switches to become normal. On the other hand, when F4 is 1, it waits for a game ball to be inserted into the special winning opening 20 and detected by the 10-count switch 92. For example, the store clerk opens the glass plate 22 to expose the game board 12, and then opens the grand prize port 20 with a fingertip and inserts the game ball there. Will do.
[0051]
If any of the causes of the abnormality is eliminated (step 350: YES), the CPU 80 resets the corresponding abnormality flags F1 to F4 to 0 (step 360) and returns to step 300.
If it is determined in step 300 that there is an error, the processing from step 320 onward is repeated. If the abnormality flags F1 to F4 are 0, the CPU 80 ends this error processing.
[0052]
In this way, if there are a plurality of abnormal places, the error code blinks and is displayed on the error display 132, so that a store clerk or the like of the amusement store can know that there are abnormalities at a plurality of places, and the error code is If it is fixedly displayed, it is understood that there is only one abnormality.
As mentioned above, although embodiment of this invention was described according to the specific example, this invention is not limited to such a specific example, and it cannot be overemphasized that it can implement variously in the range which does not deviate from the summary of this invention.
[0053]
【The invention's effect】
As described above, according to the bullet ball game machine of the first aspect, the game ball that has flowed into the branch portion can be quickly flowed out into the lower dish passage, and therefore the thickness of the entire mechanism board needs to be increased. There is no.
