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. , a winning ball compatible type that electrically detects this and releases the flow of the stored prize balls to one of the stored prize balls based on the completion of dispensing of a predetermined number of prize balls. This is prize ball ejection control, and by electronically controlling this, the prize ball flow path has a different structure from the conventional one, and the prize ball ejecting device is installed offset to one side of the back setting board, making it wider in the center. The present invention relates to a pachinko game machine that forms a void and enables discharge control that eliminates the need for a memory circuit, which is a weak point in electronic control.

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 discharging device increases and the number of times it is discharged increases, it is desirable to have a dispensing device that can sufficiently withstand the frequent repetition of the ejecting operation. Conventional mechanical ejection devices that are operated by transmitting physical force have a limit to their speed increase due to friction in each mechanism, and are also poor in durability. 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. However, there was a weakness 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.

In addition, among the electronic controls related to the ejection of prize balls,
The most reliable requirement is for the control device to accurately and reliably grasp the winning balls. However, in pachinko gaming machines, noise is likely to be generated due to static electricity on the surface of the pachinko balls.
Noise countermeasures are required to accurately determine the number of winning balls, and using an electronic memory circuit to retain the number of winning balls ensures that the number of winning balls can be retained even in the event of a power outage. Countermeasures against power outages, such as backups due to batteries, are also required. Furthermore, a very reliable detector must be used to reliably detect successive passing winning balls. Therefore, if the control related to the ejection of prize balls were to be completely electronic, the cost would be extremely high at this stage.

This invention was made against the background as described above, and includes an electric prize ball ejecting device that electrically detects a batted ball that enters a winning area and is operated by this detection signal. This makes it possible to simplify the mechanical configuration of the back setting board, and by mounting the prize ball ejecting device off to one side of the back setting board to form a wide empty space in the center. , the purpose is to increase the effective use of space on the back of the game board.

Another object of the present invention is to temporarily store batted balls that have won prizes in a plurality of prize-winning areas simultaneously or consecutively, and to discharge the prize balls that are output after one prize ball is discharged for each winning ball. By providing a means (winning ball separation device) for separating and passing subsequent winning balls one by one in response to an end signal, prize balls can be accurately ejected a number of times according to the number of winning balls. This eliminates the need for a memory circuit that electrically stores the number of winning balls, and quickly detects a shortage of spare balls or an abnormality in the flow of balls and stops operations related to ejecting prize balls, thereby reducing inconvenience to players. Our goal is to provide a pachinko game machine that you won't have to bet on.

Furthermore, another object of the present invention is to prevent malfunctions of the prize ball ejecting device by, for example, detecting the prize balls ejected by the prize ball ejecting device or the prize balls just before being ejected and generating a discharging end signal. The purpose is to prevent spin-off (idling) and to perform more accurate and reliable dispensing.

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, an entrance 16, a rotary winning tool 17, and a variable winning device 18 are provided as a winning area, and the area is surrounded by a guide rail 13 in the 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 collection shelf part 21a formed to be inclined 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. Then, the winning balls are temporarily stored by the winning ball separator 60 provided in the middle of the discharge path 22, and the stored winning balls are separated one by one based on the completion of paying out a predetermined number of prize balls. The winning ball detector 55 inside detects one ball.

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 reserve 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 reserve 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 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 discharging 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 communicates the signal of the entered prize detector 55 to the control device 50 and stores it. Based on the drive command signal from the control device 50, the sprockets 42 are rotated one after another until a predetermined number is reached.

Therefore, when an abnormality in the flow of the spare ball as described above is detected in the guideway 25, the signal forming circuit 51
However, at that point, the ejection of the prize balls is stopped, or until the ejection operation is completed, that is, until a predetermined number of prize balls have been ejected, and then the next ejection is stopped, and the signal forming circuit 51 by
The alarm lamp 58 (see Fig. 11), such as an LED display element, is lit to immediately identify the cause of the malfunction and to take prompt action. lack of,
It is designed to reliably prevent the ball from getting caught in the sprocket 42 due to a shift in the 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 has a structure that allows the S-shaped prize ball to rectify and flow downward, and also allows the falling ball 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 so as to further extend the second space portion A ₂ diagonally downward to the left, and is provided at the lower front surface of the game board 8. A large auxiliary storage section 47 is connected to the auxiliary tray 12, and when the tray 9 and the tray storage section 36 are filled with prize balls, the prize balls automatically overflow and flow downward. By configuring the machine to do this, it is possible to store a large number of prize balls without bothering the players, and it is now compatible 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 tray storage section 36 is stored upstream and the flow path conversion section 38 is also full, the ejected prize balls automatically overcome the device regulating piece 48,
It has a structure in which it flows out to the auxiliary storage section 47.

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 arranged on one side. The prize ball ejecting device 40 and the saucer storage section 3 are successively provided.
6. Attach the auxiliary storage section 47 and remove the ball from the passage 31
By arranging them in parallel, the back mechanism panels can be further consolidated, and a relatively wide empty space C can be formed in the center. The empty space C may be formed on the back of the back setting board 21 by forming the first space _A1 by making the back setting board 21 entirely integrated as in the above embodiment, or Alternatively, the collecting plate 49 may be configured to be freely attachable to the rear surface of the rear setting board 21 as shown by the two-dot chain line in FIG. good. In this way, as shown in FIG. 3, the opening from which the variable prize winning device 18 projects to the rear of the back setting board 21 only needs to be formed in the separable collecting plate 49, making it easy to punch holes. .

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 starts driving the motor 41 in response to a winning detection signal from the winning ball detector 55 in the entered prize ball separator 60, and counts the signal output from the ejected ball detector 55. When a predetermined number is reached, the motor is stopped by a discharge end signal outputted, and one discharge operation is completed.

The winning ball separator 60 is configured as shown in FIG. 11, 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 provided below the movable piece 61, and a pin 6 is provided below the micro switch 55 for detecting winning balls.
A separation actuation rod 63 is provided which is rotatably mounted by 2. The tip of the operating rod 63 is bent upward, and the bent piece 6 can protrude into the award ball ejection path 22 from the tip opening of the movable piece 61.
3a is formed, and a blocking piece 63b is formed at a position separated by one ball 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, simultaneous or consecutive winning balls will be placed on the folded piece 6 as shown in Figure 11.1.
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 11, 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. 12 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 signal forming circuit 51. A drive signal is formed based on this winning detection signal,
is supplied to the motor 41 in the prize ball ejecting device 40,
Ejection begins. At this time, if there are no spare balls in the guide path 25, no drive signal is generated even if the winning detection signal comes in, and the motor 41 and the solenoid 64 in the winning ball separator 60 are not driven. It can also be done.

On the other hand, when the motor 41 is driven to start discharging, the discharge detector 45 outputs a pulse signal for each discharged bulb, and the pulse signal is supplied to the counter 52 and counted. The count value of the counter 52 is supplied to a comparison circuit 54 and compared with the set value in the setter 53. The number of prize balls to be paid out for one winning ball is set in the setting device 53, and when the counted value of the counter 52 matches the set value, a discharge end signal is output from the comparison circuit 54. . This end signal causes the motor 41 of the prize ball ejecting device to
At the same time, 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.

Further, the signal forming circuit 51 monitors the ball's downward flow abnormality based on the signal from the downward flow abnormality detector 57 provided in the middle of the guideway 25, and when an abnormal signal is received, it outputs a winning detection signal. The discharge device 40 is not operated even if there is incoming water. The downflow abnormality detector 57 is provided for each row of reserve balls flowing down the guideway 25 in two rows.

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

For example, compared to the prize ball ejection mechanism in conventional pachinko machines, the number of parts is reduced, making the entire 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 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 plate.
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, if an abnormality such as a shortage of spare balls or ball clogging due to foreign matter is detected by monitoring the flow of spare balls and prize balls,
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.

Furthermore, in this invention, when a plurality of winning balls are generated in succession, the winning balls are temporarily stored, and the ejecting state is detected by detecting the prize balls immediately before or after being ejected in the prize ball ejecting device, When a predetermined number of prize balls have been paid out, a discharge end signal is generated, and based on this signal, the stored winning balls are passed through to one ball and the next winning detection signal is generated. After confirming the discharge in the ball discharge device, the next discharge operation is performed. Moreover, by adopting such a discharge control method compatible with winning balls, there is no need for an electronic memory circuit that requires noise countermeasures and power outage countermeasures, and winning balls can be detected separately one by one. Therefore, there is no need to provide a detector with such high performance, so the cost increase of the entire back mechanism panel can be suppressed.
