Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is used in a prize ball ejecting device, an automatic ball lending machine, a ball replenishing device, etc. of a pachinko gaming machine or a slot gaming machine arranged in a pachinko gaming store. The present invention relates to a technology effectively applied to a control system of a ball discharging device.

[Prior art and its problems] As is well known, prize ball ejecting devices for pachinko gaming machines and automatic ball lending machines such as automatic ball lending machines installed in a game store ensure that a preset number of pachinko balls are ejected. Emission is required.

Therefore, the pachinko ball ejection device that requires reliable ball ejection has a counting function for counting the pachinko balls ejected to the saucer or the storage tank, and the pachinko ball ejection when a predetermined number of pachinko balls are ejected. It is required to have a stopper function to stop.

As an ejector with a ball counting function that has been conventionally used inertially, the weight of the pachinko balls that flow down in the course of the pachinko ball passage from the supply chute that forms part of the island equipment to the pachinko ball discharge port There is one in which a ratchet wheel that rotates by one pitch per one is faced, and the rotation is stopped when the ratchet wheel rotates by a predetermined angle. In addition, although it does not have a ball counting function, a swingable ball sheath that can store a predetermined number of pachinko balls is arranged on the top of the device, and the ball sheath described above is inserted every time a coin is inserted or each pachinko ball wins. There is also one in which a predetermined number of pachinko balls stored in the ball sheath are discharged by rocking.

However, the conventional ball discharging device having the above counting function has sufficiently high accuracy when only looking at the counting function, but since the number of mechanical parts is large, the storage space becomes large, and Assembly is complicated,
There are inconveniences and drawbacks such as troublesome maintenance and inspection. on the other hand,
Since the conventional ball discharging device using a ball sheath mechanically limits the number of discharged balls per one operation, there is a problem that the adjustment becomes complicated to change the number of discharged balls.

Therefore, for example, as in Japanese Patent Publication No. 58-22783, two downflow paths having different lengths, and a seesaw-type stopper that is swingably provided so that both ends face different positions of these downflow paths, There has also been proposed a prize ball discharging device which is composed of a pair of solenoids capable of independently driving each stopper and which can discharge different numbers of prize balls. However, this prize ball discharging device can discharge prize balls of three kinds of prize balls, but cannot discharge an arbitrary number of prize balls, and the balls are completely separated between the claws at both ends of the stopper. Continuous discharge is difficult because the next discharge operation cannot be performed until the charge is accumulated in, and high-speed discharge cannot be performed. In addition, since it does not have a falling ball detector, it is not possible to discharge the prize ball accurately when the ball runs out or is clogged in the taxiway or when one discharge system malfunctions. There is a problem) because it works with the prediction that there will be a ball to be ejected between the nails.

[Object of the Invention] An object of the present invention is to provide a ball ejecting device capable of ejecting an arbitrary number of pachinko balls at high speed. Another object of the present invention is to provide a ball ejecting device capable of reliably ejecting an accurate number of pachinko balls and continuing ejection even if one of the ejecting systems fails.

According to the present invention, an actuating member is provided so that the pachinko balls before ejection intersect with a flow-down path guided in a row, and the actuating member allows or blocks passage of the pachinko balls. Is a ball discharge device capable of discharging a pachinko ball with a plurality of rows, and an operating member capable of flowing down one pachinko ball so as to intersect the path corresponding to each flow path. In order to achieve the above-mentioned object, it is possible to discharge an arbitrary number of pachinko balls at high speed by providing an electric drive source that can be driven independently corresponding to each actuating member.

[Embodiment] FIG. 1 and FIG. 2 show an embodiment of the main part of the ball discharging device according to the present invention.

In this embodiment, a gutter component 1 that constitutes the main part of the pachinko ball ejection path and a ball ejection device 2 for blocking or releasing the flow of pachinko balls that flow down in the pachinko ball ejection path are held. The holding body 3 is integrally formed. A solenoid 21 which is a driving means of the ball discharging device 2 is fixed to the holding body 3.

The above-mentioned gutter component member 1 is an alignment gutter 11 that is gently inclined.
And, the flow control gutter 13 extending substantially vertically downward from the lower end of the alignment gutter 11 and the ball flowing down at the connection part between the alignment gutter 11 and the flow control gutter 13 can be turned about 90 degrees. The adjusting part 12, the guide gutter 14 extending obliquely downward about 45 degrees from the lower end of the flow control gutter 13, and the discharge gutter 15 extending substantially vertically downward from the end of the guide gutter 14. It is configured.

A pair of support pieces 16 are projected from the outer wall of the gutter component member 1 in the vicinity of the boundary between the guide gutter 14 and the discharge gutter 15, and the support shaft 4 is horizontally mounted between the support pieces 16.

Although not particularly limited, in this embodiment, two pachinko ball discharge paths are formed. Corresponding to these two discharge paths, a pair of pachinko balls serving as operating members are provided on the support shaft 4. A fan-shaped flow prevention member 22 is rotatably mounted. A pair of solenoids 21 is provided corresponding to the flow-down prevention member 22. Then, the tip end portion of the flow-down prevention member 22 enters through the slit provided in the inner wall portion of the gutter component member 1 and projects into the guide gutter 14. The rear end of the downflow prevention member 22 is connected to the front end of the plunger 21a of the solenoid 21 via a link member 23. As the plunger 21a expands and contracts, the downflow prevention member 22 moves around the support shaft 4. It is reciprocally rotated so that the tip of the tip moves into or out of the guide gutter 14.

In addition, the side wall of the guide gutter 14 is bulged to the outside, and the storage unit 1
7 is formed, and the falling ball detector 5 composed of a transmissive optical sensor is inserted in the housing portion 17. Details of the storage unit 17 are shown in FIG. Also, the sixth
In the drawing, a slit 19 for advancing the downflow prevention member 22 formed continuously with the housing portion 17 is shown.

In addition, on the upper part of the holding body 3, the wirings for concentrating the lead wires drawn out from the solenoid 21 and the downflow detector 5 in one place and connecting with the control device of the pachinko gaming machine and the like are collectively formed from the front. A connector 6 is provided for making a connection.

Further, in this embodiment, as shown by a chain line A in FIG. 2, at the entrance of the alignment gutter 11 which constitutes the upper end of the ball discharging device 2 and the gutter constituting member 1 which is unitized as described above, that is, the starting end of the discharge path. The end portion of the supply gutter 10 for guiding the balls in the storage tank 7 for pachinko balls is connected. In the vicinity of the end of the supply gutter 10, there is a stepped pressure reducing section 1
8 is formed.

FIG. 3 shows an embodiment in which the supply gutter 10 having the pressure reducing portion 18 is unitized together with the gutter component 1 and the ball discharging device 2.

In this embodiment, each of the gutter members forming the two flow-down paths in the above-described embodiment, the flow-down blocking member 22 corresponding to each flow-down path, and the solenoid 21 as a driving means thereof are held between a pair of parallel plates 24. ing. The two sets of parallel plates 24 are integrally connected to each other by a connecting punch 25. Also, supply gutter 10
Is mounted on a connecting punch 25 arranged at the rear end of the parallel plate 24.

By this, the gutter component 1, the ball discharging device 2, and the supply gutter 10 are integrally held between the two sets of parallel plates 24, and one-touch as a ball discharging device in a pachinko gaming machine or a ball lending machine in the vicinity thereof. It becomes possible to install the device in a compact form.

In the embodiment shown in FIG. 3, a stopper pin 26 is provided on the side portion of the downflow prevention member 22 so as to be supplied to an arcuate guide hole 24a formed in the parallel plate 24, and the downflow prevention member 22 is provided. The rotation range of is regulated. Also,
In the pin 27 which is laid across the lower part of the front end of the parallel plate 24,
A spring 28 is stretched between the tip of the flow-down prevention member 22 and assists the rotation of the flow-down prevention member 22 by the return spring 21b in the solenoid 21, and the flow-down prevention member 22 is swung quickly at the end of discharge. The discharge of the falling ball can be prevented. However, when the spring 28 is provided, it is possible not to provide the return spring 21b in the solenoid 21.

In the above embodiment, the supply gutter 10 and the alignment gutter 11 can be considered as one alignment gutter. In that case, the decompression unit 18
Will be installed in the middle of the alignment gutter.

Next, the operation of the flow-down path (1) and the ball discharging device configured as described above will be described in detail with reference to FIG.

When the fan-shaped downflow prevention member 22 enters the guideway 14 as shown by the solid line in FIG. 4, the pachinko balls B aligned in the downflow path (1) are the most advanced balls B ₁ downflow. It is stopped by coming into contact with the outer peripheral surface of the blocking member 22.

At this time, two balls B ₁ and B ₂ in the guide trough 14
The dimensions of the guide trough 14 and the diversion trough 13 are determined so that the _three balls B ₃ , B ₄ , and B ₅ are housed in the diversion trough 13. Moreover, the uppermost ball B ₅ in the adjusting trough 13 is pushed by the balls B ₆ , B ₇ ... In the aligning gutter 11 to come into contact with the tapered adjusting portion 12. . The sphere B ₅ receives a repulsive force from the adjusting unit 12 by being pressed toward the adjusting unit 12, and the repulsive force is transmitted to the sphere B ₅ and the balls B ₄ , B ₃ ... Acts as if pushed up. As a result, when the flow-down prevention member 22 is retracted from inside the guide trough 14 as indicated by a broken line c in FIG. 4, the repulsive force from the adjusting portion 12 and the weight of the ball cause the flow control trough 13 and the guide trough 14 to move. The spheres B _{1 to} B ₅ immediately start to flow down.

When the balls B _{1 to} B ₅ flow down, the balls B ₆ and B ₇ in the alignment trough 11
Following this, the flow begins. Then, at the exit of the alignment gutter 11, first, it collides with the adjusting portion 12 to reduce the downflow speed,
In addition, the flow-down direction is changed from the horizontal direction to the vertical direction by about 90 ° and enters the flow regulating section 13. Since the vehicle is accelerated by its own weight there, a space between the ball and the subsequent ball that is decelerated by the adjusting unit 12 is secured. Therefore, the output waveform of the detector 5 becomes as shown in FIG. ₅ , and compared with the detection interval t ₁ of the spheres B _{3 to} B ₅ in the adjusting trough 13, the following spheres B ₆ , B ₇ ...
The detection interval t _{2 of} is widened. As a result, for example, if the solenoid 21 is demagnetized when the ball B ₇ is detected, it is possible to prevent the flow-down before the ball B ₇ passes even if the operation of the flow-down blocking member 22 is delayed. .

On the other hand, since the alignment gutter 11 is provided with the decompression unit 18, the ball pressure due to the weight of the upstream sphere transmitted through the spheres B ₁₁ , B ₁₂ , ... Therefore, a considerable part is absorbed by the decompression unit 18. As a result, the ball pressure transmitted to the ball B ₁₁ in the stopped (standby) state is the ball B ₁ in the diversion gutter 13 and the guide gutter 14.
~ B ₅ is almost not transmitted to the flow-down prevention member 2
The pressure acting on 2 also becomes smaller. As a result, the flow-down prevention member 22 can be retracted with a comparatively small force. The inclination angle of the alignment gutter 11 is preferably around 7 °.

Further, in the downflow path, the center O ₅ of the sphere B ₅ located at the uppermost position of the diversion trough 12 in a state where the downflow is blocked by the downflow prevention member 22 is aligned with the sphere B ₆ in the alignment gutter 11. ~
As will be positioned below the extension line of the center line connecting the center O ₆ ~ O ₁₀ of B _10, the dimensions of the induction gutter 14 and adjusting flow trough 13 is determined.

Therefore, the pressure transmitted from the ball B ₆ .about.B ₁₀ waiting to B ₅ produces a component of force that pushes down the ball B _5. As a result, when the downflow prevention member 22 is retracted, the uppermost ball B ₅ of the diversion gutter 13 and the succeeding ball B ₆ and the outer wall 13 a of the diversion gutter 13 are provided.
It is sandwiched between and and does not prevent the spheres B _{1 to} B ₄ from following the downward flow and attempting to flow down.

The falling ball detector 5 provided in the middle of the guide gutter 14 is
The detection optical axis F is arranged so as to come to a position slightly deviated from the center of the sphere flowing down in the trough. When the detection optical axis F is positioned so as to pass through the center of the sphere, when a plurality of spheres continuously flow down, the pulse interval of the detection signal becomes narrow and accurate counting may not be possible. . However, in this embodiment, as described above, by shifting the detection optical axis F from the center of the sphere, accurate counting becomes possible.

Further, in the above embodiment, the downflow prevention member 22 is attached so that the rotation surface of the fan-shaped downflow prevention member 22 coincides with the downflow locus of the center of the downflowing sphere, and the downflow gutter 14 moves downward from above. It is moved so as to enter inside, and stops the falling ball. Therefore, the stopper force (for example, the end of the guide hole 24a in FIG. 3 or the downflow blocking member 22 in FIG. 3 enters the stopper part that limits the rotation range of the downflow blocking member 22 due to the impact force that acts on the downflow blocking member 22 when the falling ball stops. Since it can be received at the slit end of the guide gutter 14), it is possible to easily give strength enough to withstand the impact that acts at the time of stop.

Moreover, since the sphere B _{1 at the} lowermost end comes into contact with the outer peripheral surface of the fan-shaped downflow prevention member 22 and is stopped, the sphere B _{1 at the} lowest end is between the outer peripheral surface of the downflow prevention member 22 and the wall surface of the guide trough 14. Even if it is stopped in such a manner as to bite into, when the downflow prevention member 22 is retracted, it moves away while rotating the ball B ₁ on its outer peripheral surface. Therefore, the downflow prevention member 22 can be retracted with a relatively small force, and the downflow prevention member 22
The ball is not caught between the guide gutter 14 and the wall surface of the guide gutter 14 and does not become stuck.

Further, the line connecting the center of rotation of the flow-down prevention member 22 and the center O ₁ of the sphere B ₁ at the lowermost end in the guide trough 14 is arranged horizontally. Therefore, immediately ball B ₁ is enabled under a stream when the end of the falling-blocking member 22 is disengaged from the outer periphery of the ball B _1, blocking force from ball B ₁ is lowered slightly shear with the rotation of the flow-down preventing member 22 is outside And there is no such thing as starting the flow.

Further, in the above embodiment, the angle α formed between the flow control trough 13 and the guide trough 14 may be in the range of 0 to 90 °.
If the angle is set to around 0, the speed of the falling ball accelerated in the diversion trough 13 is not significantly reduced, and the load on the downflow prevention member 22 at the time of stop can be reduced.

Further, in the above-described embodiment, in the state where the sphere is prevented from flowing down by the downflow prevention member 22, the contact point between the downflow prevention member 22 and the lowermost ball B ₁ in the guide trough 14 is separated by the diameter of the sphere. Vertical line G passing through the cut point and wall surface 15 of the discharge gutter 15
The distance d from a is smaller than the radius r of the sphere, and r-rc
The position of the terminal end 14a of the guide trough 14 is determined so as to be larger than osα (r-rcosα <d <r).
Accordingly, when the downflow prevention member 22 enters the guide trough 14 to prevent the downflow of the ball, when the last discharged ball is discharged by being pushed by the end surface 22a of the downflow prevention member 22. When it reaches the end 14a of the guide trough 14, it can flow down into the discharge trough 15 and escape from the downflow prevention member 22. Therefore, the final discharge ball will always be a guide gutter 1
5, the flow-down prevention member 22 does not obstruct the entry of the flow-down prevention member 22, and the quick discharge can be stopped.

However, the guide gutter 14 may be extended like the chain line E.

If a spring 28 is used as a means for applying a force for causing the downflow prevention member 22 to enter the guide trough 14, as in the embodiment shown in FIG.
As shown by the broken line C in FIG. 3, the line of action D of the spring 28 is substantially perpendicular to the end surface 22a of the downflow prevention member 22 when the end of the downflow prevention member 22 starts to enter the guide gutter 14. It is good to arrange. As a result, when the downflow prevention member 22 comes into contact with the ball inside the guide trough 14, the rotation speed is maximized, and the downflow ball can be stopped in a smooth manner.

By constructing the downflow path of the ball discharging device as in the above-described embodiment, it is possible to impart a stable speed and a ball interval to the downflowing balls. As a result, the downflow time T from the position where the downflow sphere is detected by the detector 5 to the downflow blocking position by the downflow blocking member 22 can be experimentally accurately known. Therefore, if the solenoid 21 is actuated to cause the downflow prevention member 22 to enter the downflow path in accordance with the downflow time T, when the last ball detected by the detector 5 has just reached the downflow prevention position. In addition, you can stop the flow of the ball.

However, in this case, it is necessary to consider the displacement time X required for the downflow prevention member 22 to actually move to the position at which the downflow ball is blocked after the demagnetization signal is applied to the solenoid 21. Since the velocity of the falling ball is stable in the above embodiment, the downflow time T is also constant, and therefore the mounting position of the detector 5 is set so that the downflow time T and the displacement time X of the downflow blocking member 22 match. You should decide.

However, although the velocity of the downflow sphere is stable in the downflow route of the above-mentioned embodiment, when the gutter forming member 1 is formed of plastic or the like, the downflow velocity may vary from product to product. Further, the restoring force of the return springs of the downflow prevention member 22 is not uniform due to variations in the manufacturing process and changes over time, so that the rotational speed of the downflow prevention member 22 varies depending on the product, and the downflow prevention timing is different. There is a possibility that it may deviate slightly.

Therefore, in the present invention, the deviation between the downflow time T from the detection position of the downflow ball to the blocking position and the displacement time X of the downflow blocking member 22 is interpolated by setting a delay time by electrical control. .

Next, an embodiment of a control device that controls the ball discharging device configured as described above to discharge a predetermined number of balls and interpolates the displacement time will be described with reference to FIG.

In this embodiment, the control of the ball discharging device is performed by using a CPU (microcomputer).

The discharge request signal S0 is input to the CPU 200. When the above ball ejecting device is used as a prize ball ejecting device of a pachinko gaming machine, the signal from the winning ball detector, when the ball ejecting device is used as a ball lending machine, the signal from the coin detector is In addition, when it is used as a replenishing device for a spare ball storage tank of a pachinko game machine or a ball lending machine, a replenishment request signal is output as the discharge request signal S0 to the CPU 20.
Input to 0.

In addition, the CPU 200 filters the discharge ball detection signals S1 and S2 from the pair of detectors 5 provided in the flow path 1 of the ball discharge device 2 after the waveforms are shaped by the waveform shaping circuits 211 and 212. Only normal detection signals are extracted and input by 213 and 214. Further, the CPU 200 is input with delay time data from the delay time setting means 210 which can be adjusted by a volume or up / down type digital setting device.

The CPU 200 has a ROM 2 which is a read-only memory inside.
01 and RAM as a memory that can be read and written at any time
202 is provided. Among them, the ROM 201 stores the balls to be discharged through the two downflow paths in the ball discharging device 2 in response to the program to be executed by the CPU 200 for controlling the ball discharging device and the one discharge request signal S0. Stores fixed data such as the number (radix 1 and 2) and wait time (discharge interval).

On the other hand, the RAM 202 is a register area or a CPU 2 which constitutes a soft timer that stores the cumulative number of balls discharged from each downflow route based on the discharged ball detection signals S1 and S2.
00 work areas are provided.

Further, the CPU 200 includes drivers 221, 222,
When the discharge request signal S0 is input, the driver 221 is driven to discharge the discharge indicator lamp LMP.
Is turned on, and the drivers 222 and 223 are driven to excite the solenoids SOL ₁ and SOL ₂ (21) as a pair of discharge driving means in the ball discharging device.

As a result, the downflow prevention member 22 is retracted into the downflow path 1, and a predetermined number of balls are discharged. 230 is a CPU
200 power supply unit.

Next, the ball ejecting device is operated by the control device,
An example of a control procedure for accurately discharging the desired number of balls will be described with reference to the flowchart of FIG.

Note that FIG. 8 shows the configuration of the register area in the CPU 200 when the discharge process is performed according to the flow of FIG.

When the CPU is activated, access is first started from the ROM 201, and the instructions of the programs stored therein are sequentially read and executed. As a result, a series of discharge processing shown in FIG. 9 is started. When the discharge process is started, first,
The discharge request signal S0 is read (routine R1) to determine whether or not there is a rising edge of the signal, that is, the discharge request signal S0.
Is changed to a high level (routine R
2). Then, when there is an edge, 1 is added to the value of the instruction register (see FIG. 8) in the RAM 202 (routine R3), and the routine proceeds to the routine R4. When there is no signal edge, the routine jumps from Routine 2 to R4. Routine R
In 4, the mode register in the RAM 202 is checked to determine whether or not the mode relating to the two discharge paths of the discharge system 1 and the discharge system 2, that is, the two ball discharge devices is “0”. Here, if the mode is "0", the process shifts to the process of the discharge system 1. Then, when the system starts to operate, the registers are temporarily set to "0", so that the determination result in the first routine R4 is YES (Y) and the routine proceeds to the routine R5.

In the routine R5, it is determined whether or not the value of the instruction register in the RAM 202 is "0". If it is "0", the process proceeds to the process of the discharge system 1. If it is not "0", that is, if ≠ 0. Go to routine R6. Therefore, when 1 is added to the instruction register in the routine R3, the routine always goes to the routine R6.

In routine R6, discharge system 1 and discharge system 2 in the ball discharge device
The two solenoids are excited to start discharging. Then, after the lamp LMP indicating that the discharge is being performed is turned on (routine R7), the discharge system 1 in the RAM 202 is discharged.
Set the mode set in the mode register of 2 and 2 to "0".
Is changed to "1", and the process proceeds to the next process of the discharge system 1 (routines R11 to R27).

In the processing of the discharge system 1, first, the mode register 1 of the discharge system 1
To determine whether the mode is "1" (routine R11). If the mode is "1", the routine proceeds to the next routine, the signal of the discharge ball detector is read, and it is determined whether or not there is an edge of the signal (R12, R13). Here, if there is no signal edge, the processing of the discharge system 1 is terminated and the processing of the discharge system 2 is started. When there is a signal edge, 1 is added to the value of the discharge register 1 in the RAM.
That is, the number of discharged balls is increased by one (routine R14).

Then, the value of the discharge register 1 is the predetermined radix 1
It is determined whether (the set number of balls of the discharge system 1) has been reached (routine R15), and if not reached, the process proceeds to the process of the discharge system 2 (routines R31 to R47).

In the processing of the discharge system 2, regarding the discharge system 2 of the ball discharging device,
The mode determination (R31) and the check of the discharged ball detection signal (R
32, R33), the discharge register is added (R34), and the number of discharged balls is checked (R35). If the predetermined number is not reached, the process proceeds to post-processing (routines R51 to R56).

In the post-processing, first, by looking at the mode registers of the discharge systems 1 and 2, it is determined whether the modes are both "3". If the modes are not "3", the process jumps to R53, where both modes are set. It is determined whether it is "4". Then, if the mode is not "4", the routine R is executed again.
The process returns to the discharge process consisting of 1 to R8.

When the number of discharged balls reaches a predetermined number (base 1) in the discharge system 1 of the ball discharging device while the above procedure is repeatedly executed, the routine R15 of the discharge system 1 process determines that the answer is YES and the routine R16. After setting the delay timer 1 of the discharge system 1 in the RAM, the mode 1 in the mode register 1
Is changed to mode 2 (routine R17). Similarly, when the number of discharged balls in the discharge system 2 reaches a predetermined number (base 2),
After the discharge system 2 processing routine R35 determines YES, the routine proceeds to routine R36, where the delay timer 2 of the discharge system 2 in the RAM is set, and then the mode 1 in the mode register 2 is set.
Is changed to mode 2 (routine R37).

When the process shifts to the post-treatment, it is determined in the routine R51 whether the modes of the exhaust systems 1 and 2 are both "3". At this time, however, since the mode is still "2", the routine jumps to the routine R53, and also here ( No) and the process returns to the first discharge process (R1 to R8). When this discharge process is executed, the mode is already "2", and therefore the routine directly jumps from the routine R4 to the discharge system 1 process.

Then, when it comes to the discharge system 1 processing, this time the routine R11
Jumps to the routine R18, the determination is YES here, the routine proceeds to the next routine R19, and the delay timer 1
Is subtracted by 1. Then, the delay timer is "0"
It is determined whether or not it has become, and if it is not "0", the process of the discharge system 2 is performed. In the discharge system 2 process, the same process as described above is performed on the discharge system 2 and then the post-process is performed.

In this way, the delay timer 1 is sequentially decreased by repeating the above procedure, and when the preset delay time for displacement time interpolation has elapsed, the delay timer becomes "0". Then, the routine proceeds from the routine R20 to R21, the discharge solenoid 1 is turned off, and the discharge is stopped. Then, the wait timer 1 is set in preparation for the next discharge (routine R
22), the mode of the mode register 1 is changed from "2" to "3" (routine R23), and then the discharge system 2 process is performed.

Also in the discharge system 2 processing, when it is determined that the delay timer 2 has become “0”, the discharge solenoid 2 is turned off, the wait timer 2 is set, and the mode register 2 is changed from “2” to “3”. (R41 to R43).

After that, when the process shifts to the post-processing, it is determined in the routine R51 that the modes of the discharge systems 1 and 2 are both "3", so the routine proceeds to the routine R52, and after turning off the lamp LMP indicating that the discharge is being performed, , Return to the first processing.

When the next discharge request signal comes in during the discharge process in the ball discharge device, the number of discharge requests is stored by reading the signal edge in the routine R2 and adding the instruction register (routine R3).

Ejection processing after turning off the ejection solenoid (R1 to R8)
Returning to step 1, since the modes of the discharge systems 1 and 2 are "3" at that time, the routine directly jumps from the routine R4 to the process of the discharge system 1. Then, the routine proceeds from the routine R11 to R18, where it is determined to be NO and the routine jumps to the next routine R24. Here, it is determined to be YES, that is, the mode is "3", and the routine proceeds to the routine R25 to wait timer 1
Is subtracted by "1" and then it is determined whether the wait timer 1 has become "0" (routine R26). If the wait timer 1 is not "0", shift to the discharge system 2 process and R
From R31 to R38 → R44 → R45, the same process is performed for the wait timer 2, and the process shifts to the post process.

When a predetermined time elapses while repeating the above procedure, it is determined in the routine R26 for the discharge system 1 process and the routine R46 for the discharge system 2 process that the wait timers have become "0", and the next routine is executed. The process proceeds to R27 and R47, respectively, changes the mode of the mode registers 1 and 2 from "3" to "4", and shifts to post-processing.

Then, in the post-processing, the routine R53 determines YES, and the process proceeds to the next routine R54 to subtract the instruction register. That is, the number of stored discharge request signals is reduced by "1" after a lapse of a fixed time after the end of one discharge process. Then, after clearing the values of the discharge registers 1 and 2 that store the number of discharge balls in each discharge route, the mode registers 1 and 2
The mode is changed from "3" to "0" again and then the first process is resumed (routine R55, 56).

By repeating the above procedure, a predetermined number of balls are discharged by the ball discharging device according to the number of discharge request signals. The CPU interrupts, for example, once every 2 msec, and executes the discharging process according to the above flow. Therefore, timer management becomes possible by counting the number of interrupts.

If it is desired to change the number of balls to be discharged once by the ball discharging device, it can be easily realized by rewriting the radix 1 and the radix 2 of the fixed data in the ROM 201.

When the number of balls to be discharged is small (for example, 5 balls), the radix is set only in one discharge register and the value in the other discharge register is set to “0”, so that only one downflow route is used. It is also possible to execute the discharge of the sphere. Further, when one of the discharging systems cannot discharge or cannot discharge a predetermined number of balls due to a ball clogging, a solenoid malfunction, or the like, the number of undischarged remaining balls or the radix 1
It is also possible to set the sum of and the radix 2 as the radix of the other discharge system so that a predetermined number of balls are discharged using only one outflow path.

[Operation / Effect] As described above, according to the present invention, the actuating member is provided so that the pachinko balls before discharge intersect the downflow path in which the pachinko balls are guided in a row, and the actuating member allows passage of the pachinko balls. A ball discharging device capable of discharging a pachinko ball by stopping or blocking it, wherein the flow-down path is formed into a plurality of rows, and one pachinko ball is flowed down so as to intersect the path corresponding to each flow-down path. Possible operating members are faced, and an electric drive source that can be driven independently corresponding to each operating member is provided, so that the downflow paths are in multiple rows and continuous discharge is possible. There is an effect that an arbitrary number of pachinko balls can be discharged at high speed. In particular, in a pachinko gaming machine that can generate a large amount of winning balls in a short time due to the occurrence of a special game state called a big hit, a device capable of discharging a high bundle like the ball discharging device of the present invention is the most. It is valid. Moreover, by providing a falling ball detector that detects a downflowing pachinko ball in the middle of the downflow path on the upstream side of the operating member, it is possible to reliably discharge a correct number of pachinko balls. Even if one discharge system fails, another discharge system can continue discharge, and it is possible to efficiently operate the game machine without playing it. Further, when the number of balls to be discharged is small, the number of total operation of the driving source can be reduced by executing the discharge of the balls by using only the one-way flow-down path, thereby reducing the occurrence of malfunction or noise.
