Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a back mechanism board of a pachinko game machine, a prize ball ejecting device related thereto, and its ejection control, and in particular, when a ball hit into the game board enters a winning area. By electronically controlling the mechanism that electrically detects and sequentially stores the number of prize balls and dispenses a predetermined number of prize balls, the prize ball ejecting device is placed on one side of the back setting board so that the falling path of the prize balls is different from the conventional one. This invention relates to a pachinko game machine which can be mounted so as to be biased towards one side to form a wide empty space in the center.

As is well known, in a pachinko game machine, when a player drives balls into the game board one by one using a firing device installed at the bottom of the game board, they collide with obstacle nails and randomly change direction as they fall. A predetermined number of prize balls are awarded to the player by entering the winning area with a certain probability. Conventionally, the payout of such prize balls has generally been carried out by using, for example, the first
This was done using a mechanical prize ball ejection device as shown in the figure.

In other words, in a conventional pachinko machine, there is a reserve ball storage tank 224 above the back setting board 21 attached to the back of the game board, and a reserve ball storage tank 224 is connected to the tank 224 to allow the reserve balls to make a U-turn in an S-shape. flowing down,
A ball chute 225 for arranging the balls is provided, a prize ball ejection mechanism section and a winning ball gathering gutter 222 are provided in the center of the back setting board, and a controller is provided at the bottom for storing the winning balls at the same time, separating them one by one, and letting them flow down. 2
60 and an operating lever 265 that is rotated by the weight of the separated winning ball, and the winning ball is connected to the winning ball via an interlocking rod 266 and a link mechanism 267 connected to the end of the operating lever 265. The resulting physical force is transmitted to the prize ball case 268 provided at the end of the ball chute 225 to activate it, and a predetermined number of prize balls are dumped onto the damper 269 provided below. The prize balls are then discharged into the tray at the front by flowing down the prize ball discharge path 236.

Therefore, in conventional pachinko machines, the mechanical structure of the back mechanism panel attached to the back of the game board is complicated, making assembly and positioning adjustment troublesome.
The space occupied by the components of the back mechanism board becomes large, making it impossible to provide a sufficient empty space at the back of the game board.
In other words, the space available for effective use of the back of the game board becomes narrower.
Another disadvantage was that it became difficult to maintain and inspect the back mechanism panel.

On the other hand, among recent pachinko machines, those that have a large variable prize winning device that uses an electric drive source to create a condition in which a large number of prize balls are awarded, so-called "Ratsuki Seven", have become popular among players, and most Machines are increasingly being equipped with large variable prize winning devices. However, in such large variable winning machines, the electric drive source often extends through the game board to the rear of the back setting board, so they are not equipped with a conventional mechanical prize ball ejecting device. However, the back mechanism panel has the disadvantage that there is not enough space to extend such a variable prize winning device.

In addition, with the adoption of such a large variable prize winning device, the chances of simultaneous or consecutive winning balls occurring are extremely increased. However, in the conventional mechanical prize ball ejection mechanism, the ejection operation is a mechanical link motion as described above, so one ejection cycle is approximately
It takes 1.5 seconds, but with current electric launchers it takes 1.5 seconds.
100 balls are fired per minute. That is, 0.6
As the ball is launched into the game board every second,
A large amount of winning balls are generated in a short period of time, and the ejection of prize balls cannot keep up, and there is a risk that the winning balls will accumulate one after another. Therefore, a high-speed prize ball discharging device is required, and as a result, a large amount of prize balls are paid out to the players, which creates a need to increase the size and strengthen the structure of the prize ball storage section.

Furthermore, as the speed of the prize ball ejecting device increases and the number of times it is ejected increases, it is desirable to have an ejecting device that can sufficiently withstand repeated ejecting operations. Conventional mechanical ejecting devices that are operated by transmitting physical force have a limit in speed increase due to friction between various mechanical parts, and are also poor in durability. Moreover, conventional pachinko machines equipped with mechanical ejection devices may become inoperable due to wear or deformation of various parts, or ball jams may occur due to foreign matter getting into the prize ball case or malalignment of the balls. However, there were weaknesses in that the ejection operation was inaccurate and uncertain due to problems such as the ejection function stopping or ejection failure. In order to eliminate such weaknesses, a monitoring function is required to detect abnormalities in the falling of prize balls.

This invention was made against the background as described above, and it electrically detects the batted balls that have entered the winning area, stores the number of winning balls, etc. based on this detection signal, and also stores the number of winning balls etc. from the control device. said controller 260 in the back mechanism panel by providing an electrically operated prize ball ejection device that is actuated by a signal;
Mechanical components such as the actuating lever 265 and the interlocking rod 266 are not required, and the prize ball ejecting device, which is miniaturized by being electrically operated, is shifted to one side of the back setting board to create a wide space in the center. The purpose of the present invention is to increase the effective use space of the back of the game board by making it possible to attach the game board so as to form the same shape.

Another object of the present invention is to individually detect and memorize even if a ball hits a plurality of winning areas at the same time, and process it electronically to accurately pay out the ball and to pay out spare balls. To provide a pachinko game machine that does not cause trouble to players by quickly detecting a shortage or an abnormal flow of prize balls and stopping operations related to ejecting prize balls.

Furthermore, another object of the present invention is to make it possible to quickly and smoothly pay out prize balls in response to a large number of winning balls in a short period of time due to the electrification of the prize ball discharging device. Another object of the present invention is to improve the durability of the ejecting device and the reliability of the ejecting operation.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

The present invention will be specifically explained below using the drawings.

FIGS. 2 to 4 show an overall configuration diagram of an embodiment of a pachinko game machine according to the present invention. The pachinko game machine 1 is rotatably attached to a machine frame 2 (see FIG. 3), which has open front and rear surfaces, while maintaining a substantially vertical posture and using hinges 3, 3 shown in FIG. A picture frame-shaped front frame 4, a glass storage frame 5 attached to the front frame 4 so as to be openable and closable, an opening/closing panel 6 similarly attached to the lower part of the glass storage frame 5 so as to be openable and closable, and the front frame 4. It consists of a glass plate held in the glass storage frame 5 behind the glass storage frame 5, and a game board 8 fixed at a constant distance.

A saucer 9 for temporarily storing a large number of elastic balls (so-called pachinko balls) is provided on the front surface of the opening/closing panel 6, and a saucer 9 is provided on the lower rear surface of the front frame 4 to receive balls one by one from the saucer 9. A ball launcher 10 is provided for knocking off an elastic ball, and an operation dial 11 and an auxiliary saucer 12 are provided on the lower front surface of the front frame 4. The above batted ball launcher 1
0 has the same configuration as a known ball launcher, so a detailed explanation will be omitted.

On the front side of the game board 8, the ball launcher 1 is installed.
A guide rail 13 that guides the ball hit by the player 0 to the upper part of the game board 8, and a large number of obstacle nails 14 that randomly change the direction of the ball falling from above are fixedly installed. A winning chaser 15, a winning opening 16, a rotary winning device 17, and a variable winning device 18 are provided as a winning area, and are surrounded by a guide rail 13 in a space between the glass plate held on the front frame 4. A gaming section is formed. In addition, at the bottom of this game section, the above-mentioned prize area 15 is accidentally dropped while falling from above.
An out hole 19 is provided to collect the batted balls that do not win a prize to the rear of the game board 8.

On the back side of the game board 8, a back setting board ₂₁ is attached to the entire surface so as to form a first space A1 having an interval where winning balls from the winning areas 15 to 18 can flow down. Various mechanisms constituting the back mechanism board 20 are set on the back side of the back setting board 21 in a superimposed manner.

Below the first space _A1 of the back setting board 21,
A collecting shelf section 21a is provided, and a winning ball ejection path 22 is provided approximately in the center thereof so as to be continuous with the first space section _A1 .
is formed, and the winning balls that enter the first space _A1 flow down there and are discharged outside the machine.

The collecting shelf 21a, which is formed to slope downward toward the center, rectifies the generated winning balls one by one in a row and guides them to the winning ball discharge path 22, and detects winning balls attached on the way. 1 with a vessel of 55
The individual destinations are detected and sequentially stored in a storage circuit within the control device 50 set above the rear setting board 21.

Further, in the first space _A1 , an out ball trough 23 is provided corresponding to the out hole 19, and is configured to discharge out balls to the outside of the machine.

Above the surface of the back setting board 21 is a preliminary storage section 2 for storing spare balls supplied from the outside.
4 is attached, and as shown in FIG. 5, by fixing the preliminary storage section 24 so as to sit on the back setting board 21, the structure is such that it can withstand the weight of the preliminary balls. An outflow port 24a is provided on one side of the downwardly sloping tip of the preliminary storage section 24, and below this outflow port 24a, the back setting board 21 is inclined to such an extent that the balls roll from the left to the right under its own weight. A guideway 25 is provided which is bent downward at the right end and then descends substantially vertically, and the terminal end of this guideway 25 is connected to the inlet of the prize ball ejecting device 40.

As shown in FIGS. 5 and 6, the guideway 25 is provided on the back surface of the back setting board 21 so as to form a gutter-shaped second space _A2 , and has a bottom portion facing the outlet 24a. A treadle lever 26 is provided so as to be tiltable, with one end protruding into the guideway 25 and a weight 27 attached to the other end. A vessel 56 is placed in front of it. This detects the presence or absence of balls in the preliminary storage section 24, issues a ball shortage signal, and contacts the general management office (not shown) to prompt ball replenishment.

In addition, the guideway 25 is provided so that the partition wall 25a gradually descends so as to automatically align and guide the spare balls in one row and two rows. They are in two rows.

In the middle of the guideway 25, the ball pressure in the guideway 25 changes slightly depending on how well the balls are stored in the preliminary storage part 24, preventing balls from becoming stuck in two or three stages. In order to do this, a swingable ball holder 28 is suspended, and a ball holding plate 29 is provided which can be tilted by pivoting one end thereof.

A ball removal mechanism 30 is disposed at the bent portion 25b of the guiding path 25, and a socket of the ball removal path 31 is made to face. The bent portion 25b is provided with a peripheral wall portion 32 that can open and close a part of its outer peripheral surface, a swinging rod 33 that swingably holds the peripheral wall portion 32, and an operating rod 34 that can freely tilt above the wall portion 32. , the locking portion 33a of the swinging rod 33 and the convex portion 34a of the operating rod 34 are configured to engage with each other, and by releasing the engagement by external manipulation, the peripheral wall portion 32 is opened and a spare ball is released. It is designed to lead to the ball removal path 31.

The ball extraction passage 31 is arranged in parallel with the guide passage 25, and the lower part of the passage is bent and buried toward the first space _A1 , and extends to the lower part of the pachinko machine 1. The spare ball is configured to be taken out of the machine.

Then, a downstream abnormality detector 57 consisting of a detection plate 57a and a micro switch 57b facing into the flow path is installed for each row in the middle of the substantially vertically descending portion of the guideway 25. Abnormalities in the flow of the spare balls due to stuck balls or dirt entering the ball are monitored, and a command signal is output to the control device 50.

That is, the downstream abnormality detector 57 detects the
Detection plate 57a and micro switch 57b facing inside
Therefore, when the spare ball is flowing down normally, the detection plate 57a is pressed by the falling ball,
A regular detection signal is output from the micro switch 57b, but if an abnormality such as a stuck ball or foreign matter occurs in the guideway 25, the detection signal of the micro switch 57b may not change even when the prize ball is being ejected. Since the detection signal of the microswitch 57b changes irregularly, it is possible to detect an abnormality in the falling of the spare ball. Furthermore, in this embodiment, the micro switch 57a is
Because it is arranged at a bend in the taxiway 25, the normal transit time for one spare ball flowing down the guideway 25 is checked, and if the actual transit time becomes longer than the normal transit time, This can be detected as a flow abnormality caused by balls adhering to the reserve ball itself or balls adhering to the wall surface of the guideway 25.

The electric prize ball discharging device 40 connected to the guideway 25 is composed of a sprocket 42 and a pulse motor 41 as a driving source, as will be described in detail later as an example, and is mounted on the back side of the back setting board 21 and one side. It is miniaturized so that it can be placed on the side.

The prize ball ejecting device 40 is a device that pays out a predetermined number of prize balls to the player when a ball hits the entered prize area and receives a signal from the winning ball detector 55 in the entered prize ball ejection path 22. The sprockets 42 are rotated one after another by a drive command signal generated based on the number of sprockets 42 until a predetermined number is reached.

Therefore, when an abnormality in the flow of the spare balls as described above is detected in the guideway 25, the control device 50
At that point, the ejection of prize balls is stopped, or until the ejection operation is completed, that is, until a predetermined number of prize balls have been ejected, and the next ejection is stopped, and the control device 50 The alarm lamp 58 (see Figure 12), such as an LED display element, is lit to immediately identify the cause of the malfunction and take prompt action. This is designed to reliably prevent balls from getting caught in the sprocket 42 due to a lack of water or a shift in discharge timing.

Below the prize ball ejecting device 40, a saucer storage section 36 is connected to the back surface of the back setting board 21 so as to extend the second space _A2 to below the prize ball ejecting device 40. There is. This saucer storage part 36 is formed in an S-shape to allow the prize balls to rectify and flow down, and has a structure that allows the falling balls to collide with a bell 37 provided below to generate an exhilarating sound. There is.

Further, as shown in FIG. 7, the saucer storage section 36 has a flow path converted so that it communicates with the saucer 9 provided at the front of the pachinko machine 1 by converting the flow path by approximately 90 degrees in the vicinity of the bell 37. The prize ball that flows down from the second space _A2 of the saucer storage part 36,
It passes through the first space _A1 and the game board 8 to reach the surface of the game board. The surface of the game board is connected through a connection gutter 39 that is integrally attached to the saucer 9, as shown in FIG.

When a ball hits a prize during the game, the prize ball discharge device 40 is driven to discharge a predetermined number of prize balls to the saucer storage section 36, and the prize balls flow down and collide with the bell 37 for an exhilarating feeling. A sound is generated and the sound is promptly discharged to the saucer 9.

As shown in FIG. 4, the flow path converting portion 38 of the saucer storage portion 36 is formed to further extend the second space portion _A2 toward the lower left side, and
A large auxiliary storage part 47 is connected to the auxiliary saucer 12 provided at the lower front, and when the saucer 9 and the saucer storage part 36 are full of prize balls, the prize balls automatically overflow. By configuring it so that it flows downward, it is possible to store a large number of prize balls without bothering the player, and it can be used with the currently popular pachinko machine called Ratsky Seven. It's summery. In other words,
A regulating piece 48 is provided in a protruding manner at the communication part between the flow path converting part 38 and the auxiliary storage part 47 in the second space A ₂ to prevent the ejected prize ball from climbing over, but the saucer 9 is full. As the temperature increases, the water is stored toward the upstream side of the saucer storage section 36 and becomes the flow path conversion section 38.
When the ball is full, the ejected prize balls automatically go over the regulation piece 48 and flow into the auxiliary storage section 47.

In addition, the auxiliary storage section 47 is located from the first space section _A2 .
The flow path is turned about 90 degrees toward the front side of the pachinko machine 1, passing under the lower part of the game board 8, and further passing through the front frame 4 to be connected to the auxiliary saucer 12. As described above, the preliminary storage section 24 and the guideway 25 are arranged above so as to form the second space _A2 on the back surface of the back surface setting board 21, and the guideway 25 is continuously provided on one side. A prize ball ejecting device 40, a saucer storage section 36,
By attaching the auxiliary storage section 47 and arranging the ball extraction passages 31 in parallel, the back mechanism panel can be further consolidated, and a relatively wide empty space C can be formed in the center. The empty space C is a first space where the back setting board 21 is entirely integrated as in the above embodiment.
A ₁ may be formed on the back of the rear setting board 21, or a collecting plate 49 can be attached to the back of the back setting board 21 as shown by the two-dot chain line in FIG. It may be configured so that it can be attached to the back of the collecting plate 49. In this way, as shown in FIG.
9, the punching process becomes easy.

FIG. 8 is an enlarged perspective view showing an example of the structure of the electric prize ball ejecting device 40.

As shown in the figure, the terminal end of the guideway 25 is bent diagonally downward and has two exit sections 25.
c ₁ and 25c ₂ are provided. This outlet section 25
A separation sprocket 42 is disposed to face c ₁ and 25c ₂ , and the sprocket 42 is fixed to the rotating shaft of a pulse motor 41 . is fixed. Further, on the outer periphery of the sprocket 42, for example, six recesses 42a and six claws 42b, which can be engaged with pachinko balls, are formed. Exit section 2 at the end of the taxiway 25
When one of 5c ₁ and 25c ₂ faces the recess 42a of the sprocket 42, the other faces the claw 42.
It is configured to face b.

Then, the blocking plate 43 and the outlet portions 25c ₁ , 2
It is positioned so as to have a distance of one ball from the end of _5c2 , and below it is provided a discharge gutter 44 connected to the upper end of the saucer storage part 36, which comes into contact with the claw part 42b. The prize ball B' that has been engaged with the concave portion 42a is held in place so that it does not flow out, and the prize ball B' that has engaged with the recess 42a comes into contact with the blocking plate 43 and is held between the following prize ball B'', and then the sprocket 42 rotates. Then, it is separated by the claw part 42b, and the lower discharge gutter 4
It is now possible to flow down to 4.

FIG. 10 shows the ejecting action of the prize ball ejecting device 40, and as shown in _{FIG .}
is sent out and separated by the movement of the pawl portion _42b1 as the sprocket rotates, and then when the ball _B3 following the ball _B1 comes into contact with the pawl portion _42b1 as shown in FIG. At this time, the ball B ₂ engages with the recess 42a ₁ and is sent downward and separated by the claw 42b ₂ . When the ball B ₄ following the ball B ₂ comes into contact with the claw portion 42b ₂ , the ball B ₃ is engaged with the recess 42a ₂ and separated by the claw portion 42b ₂ . In this way,
Due to the separating action accompanying the rotation of the sprocket 42, the prize balls aligned in the outlet portions 25c ₁ and 25c ₂ are taken out one by one alternately and discharged into the discharge gutter 44.

Further, an L-shaped notch is formed in the blocking plate 43, and as shown in FIG. 9, an ejected ball detector 45 including a plurality of sensors 45a to 45d is provided in this notch. . The above sensor 45
45a and 45b among a to 45d are the outlet portion 25
Sensors 45c and 45d are used to detect whether there is a ball to be ejected next in c ₁ and 25c ₂ , and to confirm whether or not that ball has been ejected. It can be configured using a proximity switch.

The prize ball ejecting device 40 is configured such that the winning detection signal outputted from the winning ball detector 55 is transmitted to the control device 50.
When supplied, the motor 41 is driven by the drive signal output from the control device 50 and starts discharging. At this time, the control device 50 starts discharging after confirming that the spare balls are present at the exit of the taxiway 25 based on the detection signal from the discharged ball detector 45, and also receives a prize from the discharged ball detector 45. Upon receiving a discharge confirmation signal output for each ball, the discharge state is detected, and upon determining that a predetermined number of prize balls has been reached, a discharge end signal is output to the prize ball discharge device 40, and the rotation of the motor 41 is stopped. I'm starting to let them do it.

FIG. 11 is a block diagram showing an example of a control system for the prize ball ejecting device 40 by the control device 50.

A winning detection signal (pulse) generated from the winning ball detector 55 corresponding to each winning ball is supplied to a memory circuit 51 as a storage means such as a counter, and counted, thereby determining the number of winning balls. be remembered. The control circuit 52 includes a prize ball ejecting device 40.
A detection signal from an ejected ball detector 45 is inputted therein, and when the stored value of the memory circuit 51 becomes "1" or more, a drive start signal is outputted to drive the motor 41 of the prize ball ejecting device 40. Then, the motor 41 rotates and starts discharging the prize balls, and a detection signal (pulse) is sent from the detector 45 to the control circuit 52 for each prize ball. The control circuit 52 counts this detection signal using, for example, an internal counter, and when the count value reaches a value preset in an internal setting device, it determines that a predetermined number of prize balls have been ejected, and controls the motor. The discharge is completed by outputting a drive stop signal or by stopping the output of the motor drive signal.

In addition, due to a ball clogging during discharge, taxiway 2
When the detector 45 detects that there are no balls discharged to the exit portions 25c ₁ and 25c ₂ at the end of the 5th terminal, the control circuit 52 immediately stops the motor 41 in response to the output thereof, and The value of is held as it is, and when prize balls enter the exit portions 25c ₁ and 25c ₂ , the motor 41 is operated again to discharge the remaining prize balls. When one discharge is completed, the control circuit 52 sends a signal to the storage circuit 51 to decrement (reduce) the stored contents.

In addition, a signal from the ball shortage detector 56 is inputted to the control circuit 52, so that the preliminary storage section 24
When there is no spare ball inside, a detection signal is sent to the control circuit 52.
The drive of the motor 41 may be stopped to stop discharging the prize ball when the prize ball is sent to the prize ball.

In this case, even if the ejection of prize balls is stopped, the number of winning balls is retained in the memory circuit 51, and if there is a new winning during that time, it is detected, counted up, and stored. Then, when the spare balls have been replenished into the spare storage section 24, it is preferable to start discharging the prize balls again by a control signal from the control circuit 52.

On the other hand, the control circuit 52 monitors an abnormality in the flow of the ball based on a signal from a downstream abnormality detector 57 installed in the middle of the guideway 25, where dust and foreign matter easily enter and cause ball clogging. When the discharge device 40 is overflowing, the discharge device 40 is stopped. The downflow abnormality detector 57 is provided for each row of reserve balls flowing down the guideway 25 in two rows.

In addition, the control device 50 consisting of the control circuit 52 and the memory circuit 51 detects a power outage and backs up information on the number of winning balls in the memory circuit 51 by battery so as not to be lost. It is becoming more and more common.

In the above embodiment, by changing the setting value of the setting device in the control circuit 52, an arbitrary number of prize balls can be paid out at one time.

In addition, a plurality of setters are provided in the control circuit 52 of the above embodiment to set different set values, and a winning detector is provided for each winning area 15 to 18, and the types of winnings are distinguished and stored in the storage circuit 51. It is also possible to change the number of prize balls to be ejected depending on the type of winning.

Moreover, instead of the prize ball discharge device 40 which separates and discharges the prize balls by driving the separation sprocket 42 with the motor 41 as in the embodiment, a solenoid and a flow prevention member are used. A device configured to separate and eject prize balls one by one may also be used.

As explained above, in this invention, the back mechanism panel of a pachinko game machine, the associated prize ball ejecting device, and its ejection control have been changed from the conventional purely mechanical system using the winning balls themselves to simple prize ball detection. A compact and high-speed electric prize ball discharging device using a motor or the like as a driving means, and a control device for controlling these devices and the control devices are installed on the back setting board in a functional and effective manner. Since they are arranged in a concentrated manner, various new effects not seen in the past can be achieved.

For example, the entire device can be configured more compactly compared to conventional prize ball ejection mechanisms, and if multiple winning balls occur at the same time, this is stored in the memory circuit, so the winning balls can be stored once and the winning balls can be ejected once. This eliminates the need for a complicated mechanism that separates and flows down one by one for each discharge. Therefore, the structure of the back mechanism panel is simplified, and assembly, positioning adjustment, etc. are facilitated. In addition, the prize ball ejecting device is installed offset to one side of the back setting board, and a preliminary prize ball storage section is provided above the prize ball ejecting device, and the spare balls in the preliminary storage section are automatically stored. A series of taxiways are installed to effectively rectify and guide the flow.
The downstream end thereof is connected to the inlet of the deflected prize ball ejecting device, the outlet of the prize ball ejecting device is communicated with a saucer storage section provided below the prize ball ejecting device, and the outlet of the prize ball ejecting device is connected to the tray storage portion provided below the prize ball ejecting device. By providing an auxiliary storage portion that communicates with the auxiliary tray, a wide empty space can be formed in the center of the back setting board.
As a result, maintenance and inspection of the back set board becomes easier, and this empty space can be used to install, for example, a variable winning device or display device called a large piece of hardware that protrudes greatly toward the back set board in the center of the game board. Can be installed.

In conventional pachinko machines, there was a restriction on the size of the variable prize winning device when it was attached to the game board because it was not possible to form a sufficient empty space in the center of the back setting board, but according to the present invention, It is now possible to install a large-sized variable winning device, which makes it possible to add a highly interesting variable winning device that fully satisfies players, thereby increasing the entertainment value of the pachinko machine. It becomes possible to improve the product value.

In addition, the back setting board has an overlapping structure of the first and second spaces to improve its strength and to widen the effective space, resulting in a large amount of winning balls due to the adoption of a large variable winning device. It is also possible to increase the size of the saucer storage section and the auxiliary storage section accordingly.

Furthermore, in this invention, winning balls are individually detected and processed electronically, so even if multiple winning balls occur at the same time, there is no need to stop ejecting prize balls due to ball jams. In addition to accurate payout, if we monitor the flow of spare balls and prize balls and detect an abnormality such as a lack of spare balls or ball jams due to foreign matter, etc.
Since the operation related to ejecting the prize balls is immediately stopped, empty ejection or half-hearted ejection of the prize balls is prevented, and unfair results to the players are not brought about.

In addition, the electric prize ball ejector has superior durability compared to a mechanical one, and can eject quickly and reliably, so it can quickly and smoothly handle a large number of winning balls in a row. This has the effect of allowing prize balls to be paid out.
