Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention belongs to the technical field of a ball game machine such as a pachinko machine, an arrange ball game machine, or a ball ball game machine.
[0002]
[Prior art]
A game ball supply method in which a launch ball is tilted by a rotating launch cam to launch a game ball, and a game ball is supplied to the launch position with a handle accessory attached to the launch kit by tilting the launch rod is a pachinko game. The machine is already known in Japanese Patent Publication No. 2-35586.
In addition, a device for counting game balls is a system for detecting whether or not a game ball exists inside the ball receiver by operating a ball receiver with a solenoid, and is used in an arrange ball game machine or a jig ball game machine.
[0003]
[Problems to be solved by the invention]
However, the conventional launching device of the pachinko machine is attached to the launcher at the moment the launcher launches the game ball due to the engagement / disengagement of the launch cam provided on the motor side and the roller arm provided on the launcher. Since the launcher is set back to its original position by the tension spring, the launcher will bounce with momentum when it returns.
In order to suppress this bounce as much as possible, two anti-vibration rubbers are provided. It is well known that the anti-vibration rubbers deteriorate as the operation of the pachinko machine increases.
As the deformation of the anti-vibration rubber progresses, the bounce of the launcher also increases, and the handle accessory (detailed later) hits the ball feeding lever (also shown as 86 in FIG. 8 as an example) as soon as it bounces. Then, the ball feeding lever is vibrated to operate the ball feeding (hereinafter referred to as a duck, which is dropped in addition to the concave portion formed inside the structure one ball at a time, shown as 82 in FIG. 8 as an example). Send out.
Therefore, when sending out the next game ball to the launch point, when the tilting of the launcher starts, the handle accessory activates the ball feeding device to send out the game ball to the launch point, resulting in two launch points. The disadvantage that the game balls are lined up arises.
In addition, the number of game balls that were supposed to be one when the duck was activated by the vibration of the kite was sometimes counted as two.
[0004]
As described above, with conventional pachinko machines, even if the driving state of the game ball launching device and the operation state of the ball feeding device are well adjusted, the anti-vibration rubber, shock absorbing rubber and Due to the deterioration of the spring or the like, the supply of the game ball to the launch point of the game ball which is regularly and accurately stabilized cannot be obtained, and a good flight state of the game ball cannot be maintained.
This is a little hitting the game ball replenished in the bounce, that is, when the rebounded bounce tip is timed, the game ball and the tip contact the ball and the game ball jumps in the firing direction In actual firing, the timing is not matched and the game ball is not stably stopped.
For this adjustment, it is necessary to perform work such as replacement of the vibration isolating rubber and shock absorbing rubber, position adjustment of the vibration isolating rubber, and angle adjustment of the handle accessory that operates the ball feeding lever. It is a drawback.
In addition, skilled technicians also need to make initial adjustments at the production plant.
[0005]
More specifically, FIG. 8 shows a device for launching a game ball 97 with a launching device 81 and a ball feeding device 80. A launching motor 92 is attached to the launching device 81, and a rotating shaft 95 is attached to the launching motor 92. There is a launch cam 85 on the rotary shaft 95, and the rotary shaft 95 rotates clockwise when the game ball 21 is launched.
The launcher 81 is attached to a launch dial (not shown), and a winding pulley 93 is attached to the launch dial by a mandrel (not shown).
The winding pulley 93 is connected to the firing force adjuster 90 by a tension spring 89 and a wire 96, and the firing force adjuster 90 is provided for the purpose of finely adjusting the firing force.
Turning the launch dial counterclockwise as shown in FIG. 8 starts firing, and further turning increases the firing strength and increases the flight distance.
The ball feeding device 80 is provided with a duck 82 and a ball feeding lever 86 is provided at a position where it hits the bottom surface of the duck 82.
The launcher 81 is provided with a launcher 83, and the launcher 83 is urged in the direction of arrow R by a pulling spring 89. The launcher 83 is determined jointly with the positioning vibration isolating rubber 88 and the shock absorbing rubber 91. Established at the specified angle.
When the top of the launch cam 85 reaches the roller arm 94 of the launch rod 83 by rotation of the launch cam 85, the launch rod 83 is rotated in the direction of arrow D to the launch rod 84 shown by the dotted line diagram. The arm 94 is repelled in the direction of arrow P by the pulling spring 89 biased away from the apex of the firing cam 85, and the game ball 97 is thrown away.
[0006]
The launcher 83 is provided with a handle accessory 87. When the launcher 83 moves, the handle accessory 87 activates the ball feeding lever 86, and the duck 82 moves accordingly and adds the game ball 97. When repelling in the direction of arrow P, the game ball 97 added to the duck 82 is supplied to a launch point (not shown). The firing operation can be repeated continuously while supplying the game balls 97 to the firing points sequentially.
At this time, when the launching rod 83 rebounds, the positioning vibration isolating rubber 88 and the shock absorbing rubber 91 suppress the bounce of the launching rod 83. If the adjustment is inadequate, the bounce of the launcher 83 becomes large and the handle accessory 87 operates the duck 82 to send out the game ball 97 again.
Next, the shooting cam 85 turns and the shooting rod 83 moves in the direction of the arrow D to send out the next game ball 97. If two game balls 97 are fired side by side at the launch point, of course, it will be in the desired position. The game ball 97 does not fly.
Further, if the ball feeding device 80 is provided on the back side of the upper plate (not shown), the upper plate itself can be opened and closed, and there is an unstable element that the fulcrum has variation and play and cannot be completely fixed. There is also a drawback that the engagement / disengagement relationship between the handle 86 and the handle accessory 87 does not become a fixed position.
[0007]
The above are the disadvantages that have been in the past, and this is because the player who has no luck in the game is frustrated and lifts and pushes down the upper plate, causing distortion and the timing of feeding is out of order. As long as you don't, you need to send two game balls, hit the game balls a little to make the game balls jump out in the launch direction, and the actual ball will sit in the launch direction. The aim is to provide a launcher that does not.
Next, when a player loses a game ball automatically by hitting a foreign object on the launch control lever (fixing the foreign object to the launch control lever and connecting the launch dial and the glass frame with a wire, etc.) If the player leaves the game machine that had been playing, the firing operation will not stop unless the automatic hitting is stopped. This does not stop the firing operation unless the game machine is turned off or the handle is returned.
[0008]
Next, it is not generally considered to count the game balls fired by general pachinko machines.
For example, a game machine with a first-class special electric accessory (hereinafter referred to as a first-class pachinko machine) is a big hit and the big prize opening is opened to obtain a game special prize, and a large number of prize balls are acquired. If it is possible, the grand opening will be 6 seconds in 10 ball units in a single opening, and 16 large winning openings can be opened, resulting in 160 winning balls.
An interval timer is provided between each opening, and when the time from the occurrence of the jackpot to the closing of the 16th grand prize opening is 100 balls per minute and the interval timer is 4 seconds,
The total opening time of the grand prize opening is 16 x 6 = 96 seconds.
The interval timer is 15 x 4 = 60 seconds,
60 + 96 = 156 seconds by adding the grand prize opening time and the interval timer,
If the number of winning balls at the big prize opening is 15, the total number of payouts is
160 × 15 = 2400 game balls that are shot in 156 seconds,
156 × 100 ÷ 60 = 260, and the total number of acquired balls is 2400−260 = 2140, but it is a case where all of the open big prize openings are won, and the open big prize opening is not entered. There is a game ball.
If there are a large number of game balls that could not be won in the big winning opening during this jackpot, the total number of acquired balls will decrease, that is, if the number of balls played is constant at 2400 and the number of shots is increased to a minimum of 260, this will be The result is an increase of 260 balls, which reduces the total number of balls.
If there is no data as described above for the nail adjustment that should be said to be the starting point of amusement hall management, this grasp and countermeasure cannot be achieved and it still depends on the feeling.
Note that the above calculation shows a case where only the big winning opening is considered without considering winning in other winning openings.
The present invention has been made in view of the above drawbacks, and this solution will be described next.
[0009]
[Means for Solving the Problems]
  A bullet ball game machine according to claim 1, wherein a game board, a plate to which the game board can be detachably fixed and a launch rail is fixed to a lower part, and a ball feeding device for supplying a game ball to a launch point of the launch rail And a launching device that launches a game ball replenished to the launching rail toward the game board, wherein the launching device receives power from the drive source of the launching device. A power transmission device for transmitting to the device is provided, and the ball feeding device includes a ball passage to which a game ball is supplied from an upper plate, and a ball passage connected to the power transmission device and rotating synchronously with the launching device. And a feeding cam that guides the game ball from the replenishing port to the firing rail, and a mounting portion that is a recess in the vicinity of the firing point of the firing rail. Detachable ball feederattachment,
  The power transmission device includes a drive gear that is attached to the launch cam shaft on the launch motor side that is the drive source and rotates around the launch cam, and a follower gear that is connected to the feed cam and provided on the feed shaft that rotates around And a timing belt hung on the drive gear and the follower gear,
  The feed cam is connected to the feed shaft by a brake structure by a ratchet mechanism that is biased and pressed by a spring against the feed shaft,
  A game ball detection device for detecting the passage of the game ball sent from the ball feeding device is provided,
When the ball detection device does not detect a game ball, the launching device is stopped after a set time.
It is characterized by that.
  By providing the ball feeding device on the plate, the launching device and the ball feeding device are completely fixed linearly with the game board with respect to the game board, and stable ball feeding can be performed.
  Since the ball feeding device is attached to the concave portion of the plate, the firing rail is not covered, so that it is not difficult to clean the firing rail.
[0010]
  Ball feederWhen it is provided on the back side of the upper plate, the upper plate itself can be opened and closed, and there are manufacturing variations and play at the fulcrum, which is an unstable factor.
  The conventional plate is attached to the inner frame and fixes the game board to the inner frame.
  The plate is provided with a thickness suitable for the game board, and the inside is hollow and not effectively used.
  A concave part to which the ball feeding device is attached is provided in the vicinity of the launch point of the plate, and the ball feeding device is detachably attached to the concave part so as to be stably fixed.SoSince the cleaning of the firing rail is conventional and fixed to the plate, the ball feeding may go mad during operationDisappear.
[0011]
  The power transmission device isA drive gear attached to the launch cam shaft on the launch motor side which is the drive source and rotated around the launch cam; a follow-up gear provided on the feed shaft connected to the feed cam; and the drive gear; The timing belt hung on the following gearPrepared
  The feed cam is connected to the feed shaft by a brake structure with a ratchet mechanism that is biased and pressed by a spring against the feed shaft, and the feed cam is a ratchet that is biased and pressed by a spring against the feed shaft. It is connected to the feed shaft by a brake structure by a mechanism.
  Since the power of the firing cam shaft is transmitted to the feed cam by the drive gear, the follower gear, and the timing belt, the synchronous rotation of the rotation of the firing cam (fire) and the rotation of the feed cam (replenishment) becomes accurate. It is possible to set the timing at which the ball can be fired when the game ball replenished to the firing rail from the ball feeder is stably stopped.
[0012]
As described above, when the lever is used, the timing of hitting the lever is delayed due to wear of the sliding surface of the lever. This must be adjusted by changing the shape of other parts that sometimes hit the lever. If the adjustment is mistakenly made to reduce the interval, the operation timing is advanced, and if the interval is widened, the operation timing is delayed.
To eliminate this drawback, operating the ball feeding device with a shaft or belt from the shaft of the motor uses a gear for a shaft drive, and a timing belt for a belt. This makes it possible to synchronize with the natural and smooth and stable ball feeding.
In addition to this, it is also possible to configure the wire with a transmission direction that can be freely configured. If the wire between the motor shaft and the rotating body of the ball feeding device is connected with this wire, the configuration can be further simplified.
In addition, a method of rotating the ball feeding device with a motor or a rotary solenoid may be considered, and the ball feeding device may be operated in electrical synchronization with the firing motor.
[0013]
  Also,Provided is a game ball detection device for detecting the passage of a game ball sent from the ball feeding device, and when the ball detection device does not detect a game ball, the launch device is stopped after a set time.It is.
  It is conceivable that the ball cannot be fed due to a failure of the power transmission device. If a game ball detecting device is provided, the ball ball feeding device is used when the game ball detecting device does not detect the game ball even though it is urging the launch. It becomes possible to consider it as a failure.
  In addition, when a game ball detecting device is provided, when the player automatically hits and the game is interrupted and there is no game ball in the ball feeding device, the launching device is moved uselessly. It is possible to stop the launching device by providing a game ball detection device when it cannot be detected.
  As a next example of the method of using the game ball detection device, it is possible to stop the motor at a fixed point because the shooting and ball feeding are synchronized. If the energization of the motor is stopped at the time of detection, the motor is not burdened when it is restarted because it is the time when the launcher has finished firing.
  If it is the above structure, a motor will carry out about a half rotation, and it will be in the position where the firing cam of a motor shaft begins to contact the roller arm of a launching rod.
[0014]
Next, the provision of the game ball detecting device can be effectively used even in a game machine that counts the number of shots such as an arrange ball game machine or a jig ball game machine.
This means that it is possible to share the frame device between the arrange ball game machine, the jiyan ball game machine and the like and the pachinko machine.
The counting of the fired balls mentioned in the above-mentioned drawback is to count the number of fired balls with the game ball detection device of the first kind pachinko machine and see how many balls could not be entered with the number of winning balls and the number of fired balls at the time of the big hit Therefore, the player is dissatisfied if the total number of balls acquired is a little, and when it is used as a guideline for good and bad game machines, it is determined by this value, that is, the difference between the total number of shots for the number of winning prizes. .
For the design of a gaming machine with a prize opening that is opened in time, such as a first-class pachinko machine, the position of the game nail can be determined based on this difference value, and even at pachinko shops, Can be used as a reference for firm data on nail adjustment.
The game ball detection device adopts a constant speed passing method unlike a conventionally known pause detection method such as pressing with a game ball or a method of detecting a game ball in a duck format. Even a deformed game ball can be detected, and ball clogging does not occur.
[0015]
Further, in the pause detection type such as a game ball is pushed by a conventional game ball detection device, when a game ball detection switch or a game ball detection sensor is used for detection of the game ball in the method of detecting the game ball, the game ball is detected. Since the detection switch or the game ball detection sensor has a limitation of the duty interval that is a detection range, there are cases where a missing game ball or a deformed game ball cannot be detected. In the duck form, the movement is a reciprocating motion, so excessive counting occurs due to bouncing, and there is a duck type that is driven by a solenoid, but the wear is severe and replacement of parts called ducks and replacement of the ball feeder itself You may be forced to do so.
Speaking of why the duck wears, as anyone can understand the operation of the solenoid, when the solenoid is energized and de-energized, the solenoid generates an impact that is struck with a hammer and applies that impact to the duck and game ball. As a result, the inertia is several times the weight of the game ball.
The impact generated by this inertia and the impact of the solenoid itself result in the wear of all the parts linked to the solenoid.
As described above, in the detection of the game sphere, the constant speed passing method has the most excellent effect as compared with other game sphere detection methods.
[0016]
  The mounting method of the ball feeder isA pin may be provided in the recess serving as the attachment portion, and a hole for the pin may be provided in the ball feeding device so that the ball feeding device is loaded on the pin.
  A pin of the same quality as the plate is provided at a specific position in the concave part of the plate, and this pin is tapered so that a cylinder with a tapered hole in the shape of a pair of this pin is provided with the same quality as the ball feeder. If the taper hole of the ball feeder and the taper pin on the plate side are pushed in to communicate with each other, stable fixation can be easily performed.
  Although there is a possibility that the ball feeding device may fall off due to vibration, a stopper for preventing the dropout may be provided. If a lid is provided on the plate side, this dropout can be prevented.
[0017]

When a player bites a foreign object between the launch handle 19 and the launch control lever 20 and automatically launches and the player disappears and the game ball 24 disappears, the launch motor 34 operates wastefully. Become.
In this embodiment, since the ball detecting device 43 is provided, when the ball detecting device 43 does not detect the game ball 24, it is stopped after a set time, and when the game is played again, the launch adjusting lever 20 is temporarily turned counterclockwise. If it is returned to the direction and the launch adjusting lever 20 is then set to the launch start posture, it is more effective because it is incorporated on the software so as to start launch.
[0029]
Next, FIG. 7 is a structural view of the upper plate 15 provided for the product of the present invention, wherein (a) is a plan view (b) is a front view (c) is a rear view (d) is a right side view.
The upper plate 15 is provided with a ball stop 61. When the upper plate 15 is closed to the inner frame 14 as shown in FIG. Therefore, if the glass frame 18 not described in detail is further closed thereon, the tip of the ball stop 61 hits the glass frame 18 to open the upper tray supply port 68.
When opening the upper plate 15, when the glass frame 18 is opened and the catch 63 of the upper plate 15 is operated, the upper plate 15 is opened and the ball stopper 61 that has opened the upper plate supply port 68 is returned to supply the upper plate. The mouth 68 is closed.
Accordingly, when the upper plate 15 and the glass frame 18 are closed in this order, the game ball 24 in the upper plate 15 flows into the ball passage 67 through the upper plate supply port 68, and when the upper plate 15 is opened, the game ball 24 flows into the ball passage 67. To prevent it.
When the upper ball removal lever 21 is operated, the return ball outlet 66 shown in (c) is discharged from the return ball outlet 66 and the game ball 24 in the upper plate 15 is guided to the lower plate 16 through a lower plate passage (not shown).
[0030]
The upper plate 15 is provided with a ball rubbing 58, and the ball rubbing 58 jumps to the side when the game ball 24 led out from the feeding cam 42 strikes this surface excessively to prevent damage and when the game ball 24 is fired. It is provided for the purpose of preventing this.
The ball rubbing 58 is constituted by a ball rubbing main body 59, and a ball receiver 65 is provided on the upper portion so that the game ball 24 jumping out of the ball does not enter the launch rail 37. In addition, since the ball return hole 60 is provided, the game ball 24 which bounces off and jumps out is guided to the lower plate 16 from the return ball outlet 66 through the ball return hole 60 through a passage (not shown in detail).
Next, when a foreign object not described in detail in FIG. 5 is caught in the feed cam 42, the feed cam 42 is a ratchet mechanism in which a feed cam a42a and a feed cam b42b are urged and pressed against the feed shaft 46 by a spring. Therefore, the ball feeding device 38 is not broken even if the firing motor 34 rotates.
[0031]
【The invention's effect】
Since the ball feeding device 38 described above has the structure shown in claims 1 to 3, the launch motor 34 and the ball feeding device 38 rotate at the same rotational speed and can be smoothly synchronized. That said, there is no such thing as two game balls being sent by bouncing of the launcher 83, which is the conventional defect described in the problem. This means that the player can be immersed in the game by eliminating the vibration of the ball feed transmitted to the launching handle 19 that the player dislikes and the vibration noise caused by the vibration. There is an effect that leads to an increase.
[0032]
According to the fourth aspect of the present invention, in the present embodiment, it has been said that a foreign object is bitten by the firing handle 19 with a gesture often performed by the player, and when the player disappears, the upper plate 15 If the ball detection device 43 does not detect the game ball 24 after a set time without the game ball 24, the launching device 27 is stopped to prevent unnecessary sky emission. Play. When operating again, once the firing handle is returned to the original position in the counterclockwise direction, the firing operation can be performed once again in the firing posture.
In addition, when the game board is changed to a game machine with a break such as an arrange ball game machine or a Jiyen ball game machine, the number of shots can be counted, so the game content can be easily changed.
Since the fixed point operation of the firing motor can be stopped, it can be started smoothly.
As shown in claim 5, since the ball feeding device can be easily attached and detached, even if there is a failure or the like of the ball feeding device, the ball feeding device can be easily replaced simply by refilling.
As described above, the effects of the present invention have not been seen so far, and can be said to be excellent because the handling is easy and smooth operation can be obtained in both the production factory and the game hall.
