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, 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. By electrically detecting this, maintaining the prize winning state, and dispensing a predetermined number of prize balls by a control system using a microcomputer, the prize balls can be controlled by a microcomputer. Relating to a pachinko game machine in which the ejecting device and its flow path are structured differently from conventional ones, and the prize ball ejecting device can be mounted offset to one side of the back setting board, thereby forming 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, the balls 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, such payout of prize balls has been carried out by a mechanical prize ball ejector, such as the one shown in FIG. It was supposed to be done by a device.

In other words, in a conventional pachinko machine, there is a reserve ball storage tank 224 in the upper part of a back mechanism 220 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 fall while making a U-turn in an S-shape. A ball chute 225 is provided to align the balls, and a prize ball discharge mechanism and a winning ball collecting gutter 222 are provided in the center of the back of the game board, and the lower part stores the winning balls at the same time and separates them one by one and lets them flow down. controller 260
and an operating lever 265 that is rotated by the weight of the separated winning balls.
The physical force generated by the winning ball is transmitted to the winning ball case 268 provided at the end of the ball chute 225 through an interlocking rod 266 and a link mechanism 267 connected to the end of the ball chute 225. is activated, a predetermined number of prize balls are discharged onto a damper 269 disposed below, and a prize ball discharge path 236 is further made to flow down to discharge the prize balls into a saucer in the front.

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, it is desirable to have a prize ball ejecting device that can sufficiently withstand the repeated ejecting operations that occur as the speed of the prize ball ejecting device increases and the number of times it is ejected increases. Conventional mechanical ejection devices operated by mechanical force transmission are
There is a limit to how high the speed can be increased due to friction in each mechanical part, and the durability is also poor. Furthermore, 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. , the ejection operation may be inaccurate due to problems such as the ejection function stopping or ejection failure.
The weakness was uncertainty. In addition to eliminating these weaknesses, electronic prize ball ejection control is required as the speed of the prize ball ejecting device increases and the number of ejected balls increases.In particular, it is necessary to detect ejected prize balls or prize balls just before being ejected. Therefore, a means to detect the discharge state becomes necessary.

This invention was made against the background as described above, and includes a control device that electrically detects a batted ball entering a winning area and forms an appropriate control signal based on this detection signal, etc. By providing an electric prize ball ejecting device that is operated by a signal from the device, the mechanical configuration of the back mechanism panel can be simplified, and the prize ball ejecting device can be placed on one side of the back setting panel. The object of the present invention is to increase the effective space available at the back of the game board by mounting the game board so as to deviate toward the side and form a wide empty space in the center.

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 prize balls. To provide a pachinko game machine that does not cause unfairness to players by quickly detecting a shortage of prize balls and stopping operations related to ejecting prize balls.

Another object of the present invention is to make it possible to respond to a large number of winning balls in a short period of time by electrifying the prize ball discharging device and quickly and smoothly dispense the prize balls. , and to improve the durability of the ejection device.

Furthermore, the present invention provides a means for detecting the ejected prize ball or the prize ball just before being ejected in the prize ball ejecting device to detect the ejecting state, and based on the output from the ejecting state detecting means, a microcomputer etc. The control device determines when a predetermined number of prize balls have been reached and generates an ejection end signal to end the ejection, thereby preventing malfunctions such as idling of the prize ball ejecting device or premature ejection of prize balls. To prevent this, and to enable more accurate and reliable payout of prize balls.

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.

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 back surface of the front frame 4, where balls are supplied 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 tray 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 region, and are surrounded by a guide rail 13 in a space between the glass plate 7 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 1 is accidentally dropped while falling from above.
An out hole 19 is provided for collecting the batted balls that did not win in the prizes 5 to 18 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, the preliminary storage section 24 is seated and fixed on the back setting board 21, so 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, and when there are no balls, it issues a ball shortage signal and contacts the general management office (not shown).
This is to encourage the replenishment of balls.

Further, the guiding path 25 is provided so that the partition wall 25a gradually rises so as to automatically align and guide the spare balls in one row and two rows. There are lines.

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, and the balls overlap in two or three stages to prevent the ball from getting stuck. In order to prevent this, a swingable ball holder 28 is suspended, and a ball holding plate 29 is provided which can be tilted by pivoting one end.

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 portion 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 an external operation, the peripheral wall portion 32 is opened and the spare ball is released. It is designed to lead to Tama-Nukiro 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.

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 2), 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 part 38 of the saucer storage part 36 is formed so as to extend the second space part _A2 toward the lower left diagonally to the lower front of the game board 8. A large auxiliary storage section 47 is connected to the provided auxiliary saucer 12, and when the saucer 9 and the saucer reservoir 36 are filled with prize balls, the prize balls automatically overflow and flow downward. By configuring it to flow out, it is possible to store a large number of prize balls without bothering the player, making it possible to cope with the currently popular pachinko machine called Ratsky Seven. .

In other words, the flow path conversion section ₃ in the second space A2
A regulating piece 48 is provided in a protruding manner at the connecting portion between the receiving tray 9 and the auxiliary storage section 47 to prevent the ejected prize ball from climbing over it, but as the receiving tray 9 becomes full,
When the flow path converting part 38 is filled up by being stored toward the upstream side of the saucer storage part 36, the ejected prize balls automatically overcome the regulation piece 48 and flow out to the auxiliary storage part 47. ing.

In addition, the auxiliary storage section 47 is located from the second 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 space C can be formed in the center. The empty space C is a first space where the back setting board 21 is completely integrated as in the above embodiment.
A ₁ may be formed on the back of the back setting board 21, or a gathering board 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 such that it can be attached to the back of the collecting plate 49. In this way, as shown in FIG.
9, the hole 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 ₃ 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. Also, microcomputer (CPU)
The control circuit 52 includes a prize ball ejecting device 4, etc.
A detection signal from the ejected ball detector 45 within 0 is input, and when the memory 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 the internal setting device, it determines that a predetermined number of prize balls have been ejected, and starts the motor. outputting a drive stop signal or stopping the output of a motor drive signal to finish discharging.

In addition, due to a ball clogging during discharge, taxiway 2
When the detector 45 detects that there are no balls to be discharged to the exit portions 25c ₁ and 25c ₂ at the end of the control circuit 52, the control circuit 52 immediately stops the motor 41 in response to the output thereof, and the counter 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 memory circuit 51 to tecrement (decrease) the memory 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.
Even when the prize ball is sent to the prize ball, the driving of the motor 41 may be stopped to stop discharging 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. When the reserve balls are replenished into the reserve storage section 24, it is preferable that the ejection of prize balls is started again in response to 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 flow-down abnormality detector 57 installed in the middle of the guideway 25 where dust and foreign matter easily enter and cause ball clogging, and the abnormality signal is detected. The ejecting device 40 is not operated when a foreign object enters the room. That is, as described above, the flow abnormality detector 5
7 consists of a detection plate 57a facing into the guideway 25 and a micro switch 57b (see Fig. 4), so 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 will not change even while the prize ball is being ejected. In addition, since the detection signal of the micro switch 57b changes irregularly, it is possible to detect an abnormal phenomenon in which the spare ball flows down. Furthermore, in this embodiment, since the microswitch 57a is disposed at the bent portion of the guideway 25, the normal transit time for one spare ball flowing down the guideway 25 is checked. When the actual passing time becomes longer than the normal time, it can be detected as a flow abnormality caused by ball dirt attached to the reserve ball itself or ball dirt attached to the wall surface of the guideway 25. The downstream abnormality detector 57 is arranged for each row of balls flowing down the guideway 25 in two rows.

Further, in this embodiment, as shown in FIG. 4, a detection signal output from an out ball detector 71 provided midway through the out ball trough 23 is input to the control circuit 52. The control circuit 52 is configured to receive a signal from the number-of-balls setter 72, and determines the number of prize balls and the number of out balls based on the input prize detection signal or the discharge detection signal and the out ball detection signal. The profit and loss status is monitored by calculating the difference between the two, and when it reaches the number of stoppages set in advance by the setting device 72, a stoppage signal is generated. For example, the electric batted ball launching device 10 is stopped by this hitting stop signal. In this case,
A display device 73 for displaying the above-mentioned profit and loss status may be provided on the front surface of the game board, and may be displayed in digital numbers according to a signal from the control circuit 52.

Further, in the embodiment described above, by changing the setting value of the setting device in the control circuit 52, it is possible to make an arbitrary number of prize balls payout 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.

Furthermore, 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.

Furthermore, the control circuit 52 and the memory circuit 51 are backed up by a battery in order to detect the power outage and retain the information on the number of winning balls in the memory circuit 51 so that it will not be lost. There is.

Next, another embodiment of the present invention will be described.

In this embodiment, instead of the memory circuit 51 that electrically stores the number of winning balls upon receiving the winning detection signal, it physically stores simultaneous or consecutive winning balls and separates them one by one each time the prize ball is ejected. A winning ball separator 60 is provided in a part of the winning ball discharge path 22.

The winning ball separator 60 is configured as shown in FIG. 12, for example. In other words, winning ball ejection path 2
2 is once bent sideways at the entrance to form an opening 22a, and a movable piece 61 is rotatably provided at the bottom of this opening 22a. A micro switch 55 for detecting winning balls is disposed below the movable piece 61, and further below it is a separation operating rod 63 rotatably attached by a pin 62.
is provided. The tip of this operating rod 63 is bent upward, and a bent piece 63a that can protrude into the award ball ejection path 22 from the tip opening of the movable piece 61
is formed, and a blocking piece 63b is formed at a position one ball distance away from this bent piece 63a.

The separation actuation rod 63 is rotated by a solenoid 64 disposed below it, and separates the winning balls one by one. In other words,
Before the winning ball enters the discharge path 22, the operating rod 6
3 is rotated upward, and the bent piece 63a at the tip protrudes into the discharge path 22. Therefore, the winning balls at the same time or consecutively will be placed on the folded piece 6 as shown in Figure 12.1.
The movable piece 61 is rotated downward by the weight of the leading winning ball, and the micro switch 55 is turned on.

Then, the prize ball ejecting device 40 is driven, and the solenoid 64 is energized to operate the operating rod 6.
3 is rotated downward, and the first winning ball is shown in Figure 12, 2.
The subsequent winning balls are flown down into the discharge path 22 as shown in FIG. When the prize ball ejection completion signal is output, the power to the solenoid 64 is cut off, and the operating rod 63 is rotated upward by the repulsive force of the spring 64a. Then, the blocking piece 63b is disengaged and the next winning ball moves onto the movable piece 61, turning on the micro switch 55.

In this way, the winning balls are separated one by one in the winning ball separator 60, a detection signal is output for each winning ball, and the winning balls are discharged.

FIG. 13 is a block diagram showing an example of an electrical control system for the prize ball discharge device 40 and prize ball separator 60.

A winning detection signal (pulse) generated from the winning ball detector (micro switch) 55 for each individual winning ball is supplied to the control circuit 52. A drive signal is formed based on this winning detection signal and is supplied to the motor 41 in the prize ball ejecting device 40 to start ejecting. However, at this time, taxiway 25
If there is no spare ball inside, a drive signal will not be generated even if a winning detection signal is received, and the motor 41 and the solenoid 64 in the winning separator 60 may not be driven.

On the other hand, when the motor 41 is driven to start ejecting, a pulse signal is output from the ejected ball detector 45 for each prize ball, which is supplied to the control circuit 52 and counted by an internal counter. The count value of the counter is compared with the set value of the internal setter. The number of prize balls to be paid out for one winning ball is set in the setting device, and when the counted value of the counter matches the set value, a discharge end signal is output from the control circuit 52. In response to this end signal, the motor 41 of the prize ball ejecting device is stopped, and the solenoid 64 in the winning ball separator 60 is demagnetized.

Therefore, when the number of ejected balls reaches a predetermined number, the ejection of the prize balls is finished, and the subsequent winning balls are separated and detected in the winning ball separator 60, and the above operation is repeated again until the predetermined number of prize balls are ejected. It is done.

As explained above, in the present 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 pure mechanical system using the winning balls themselves to an electronic method for ejecting the winning balls. This is an electric prize ball discharging device that is miniaturized and can be discharged at high speed using a motor or the like as a driving means, and these devices and the microcomputer that controls them are installed on the back setting board in a functional and effective manner. Since they are arranged in a concentrated manner, it is possible to provide a pachinko game machine that exhibits various new and unprecedented effects, such as being able to form a wide empty space in the center.

For example, compared to the prize ball ejecting mechanism in conventional pachinko gaming machines, the number of parts is reduced, making the entire ejecting device more compact. becomes easier. In addition, the prize ball ejecting device is mounted 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 guideway for effectively rectifying and guiding the flow is provided, the downstream end of which is connected to the inlet of the deflected prize ball ejecting device, and the guide path is connected to the receiving tray storage section provided below the prize ball ejecting device. By communicating the outlet of the prize ball ejecting device and by connecting the tray storage section with an auxiliary storage section 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 variable winning device, which makes it possible to add a highly interesting variable winning device that fully satisfies players, increasing the entertainment value of the pachinko machine and making it a product. It becomes possible to improve the value.

In addition, the back setting board has a layered structure in which the first and second spaces are overlapped to improve its strength and to widen the space that can be used effectively. It becomes possible to increase the size of the saucer storage section and the auxiliary storage section that accommodate the generation of winning balls.

Furthermore, in this invention, winning balls are individually detected and processed electronically by a microcomputer control system, so even if multiple winning balls occur at the same time, the prize ball ejection function will stop due to ball jamming. Not only is there no problem, but accurate payout is performed, and the lack of prize balls can be reliably detected and discharging can be stopped, so that no unfair results are caused to the players.

In addition, since we used an electric prize ball ejecting device,
It is more durable than a mechanical type, and can be ejected at high speed, allowing for quick and smooth payout in response to a large number of successive winning balls.

Moreover, in this invention, a means is provided for detecting the ejected prize ball or the prize ball just before being ejected in the prize ball ejecting device to detect the ejecting state, and the CPU etc. is controlled based on the output from the ejecting state detecting means. Since the device determines when a predetermined number of balls have been ejected and generates an ejection end signal to end the ejection, abnormalities such as ball clogging due to lack of spare balls or foreign matter may occur. In this case, the operation related to ejecting the prize ball is stopped, and there is an effect that empty ejection or half-hearted ejection of the prize ball is prevented.
