CONSTITUTION:When pachinko balls inflowed from passages 57a, 57b of a guide gutter 41 flow down in any discharge path, projections 90a, 90b displace each ball from the central base frame 76 side little by little toward covers 77, 78 and also widen a certain amount the spacing of two discharge paths at the grounding part of discharge sensors 74a, 74b as described later, wherein arrangement is such as to provide continuity to a divergent flow wall 58 of the guide gutter 41 at the flow-in ends of flow-in gutters 71a, 71b, i.e., rising is made gradually from the flow-in part to downstream of a slope 79 being equal to the wall thickness of the divergent flow wall 58 of guide gutter 41 to get a specified height at the end of the slope 79, and thereafter formation is made till the flow regulation part 85 of flow regulator gutters 72a, 72b with the height held as specified. This widens the spacing of the two discharge paths in the part where discharge sensors 74a, 74b are installed.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a prize ball ejecting device for a pachinko machine.

(Prior Art) Recently, many pachinko machines have variable winning devices that generate special games with high winning rates depending on the game conditions. This type of pachinko machine generates winning balls one after another when a special game occurs, and continuously discharges a large amount of prize balls in response to the winning balls. However, as a device for processing winning balls and prize balls, a mechanical device using a ball sheath or the like has conventionally been used, and there is a limit to the speed of processing with this device.

Therefore, in order to speed up such prize ball processing, the winning balls and prize balls are detected using electrical sensors, and the winning balls and prize balls are entered into the processing path and the prize ball discharging path respectively. It has been considered to provide a flow prevention member (stopper member) and an electric driving means thereof, and to perform prize ball processing by moving the flow prevention member forward and backward based on detection by a sensor.

These electronically controlled types have the advantage of not only being faster in ejection, but also having a simpler structure than mechanical types, and being able to easily change the number of balls awarded.

(Problem to be Solved by the Invention) Such an electronically controlled device has a discharge system that has two discharge systems in order to discharge prize balls that are rectified and guided in two rows from a storage tank through an induction gutter. However, in this case, the placement of the sensor (emission sensor) is a problem.

In other words, a sensor that can detect consecutive prize balls has a structure that surrounds at least three sides of the detection port, so if there are two ejection systems and two sensors are installed side by side, the area around the detection port The specified spacing must be the same as the thickness of the

For this reason, it is possible to arrange sensors by forming both exhaust systems individually or by increasing the distance between the discharge passages of both exhaust systems. By separating the balls and connecting them to the discharge paths of each discharge system, or widening the gap between both rows of guide troughs and aligning them with the discharge paths of each discharge system, prize balls from both rows of guide troughs can be discharged separately. I was trying to guide him down the road.

However, with this structure in which both rows of guide troughs are separated into two directions, the portions that connect to the respective discharge channels become euhedral channels, and as a result, when prize balls flow from the guide troughs into the discharge channel, The flow may fluctuate or wear may occur locally.

Furthermore, if the distance between the two rows of guide troughs is widened, the thickness of the dividing wall will increase, making it difficult to obtain a good alignment of the balls, which may lead to ball clogging.

On the other hand, if both exhaust systems are formed individually, or if the gap between the re-exhaust passages is increased on one side, the structure will become complicated and the thickness of the partition walls that define the exhaust passages will become thicker, making it difficult to manufacture. This inevitably leads to poor performance and increased costs.

Note that if there is only one ejection system, the ejection sensor can of course be arranged without any problem, but with one system it is not possible to eject a large amount of prize balls in a short time, and it is not possible to speed up the prize ball processing.

This invention aims to solve these problems.

(Means for Solving the Problems) This invention forms an induction gutter that rectifies and guides prize balls in a storage tank into two rows, and a prize ball is placed in two parallel discharge paths following both rows of the induction gutter. In a prize ball ejecting device for a pachinko machine in which an ejecting mechanism for ejecting and a sensor for detecting prize balls are arranged, a partition wall between the two ejecting passages has a band-like shape that gradually rises toward the senna from the inlet or midway of the ejection passage. A protrusion is formed, thereby increasing the spacing of the re-ejection path at the sensor location.

(Function) Therefore, while it is possible to place a sensor in the re-discharge path,
The prize balls in both rows of the guide gutter smoothly flow into their respective discharge channels without shifting or clogging the balls, and the inflowing prize balls smoothly flow through their respective discharge channels along gradually rising band-shaped protrusions. flows down to.

Then, when the discharge solenoids 92a and 92b are energized from the non-energized layer, the 12th! ! 1(B), the locking claws 91a, 91b rotate upward due to the pulling of the link 94, and the locking claws 91a, 91
The refining stop part b retreats into the slit, so that the flow regulating part 8
The pachinko balls in 5 are released from the locking claws 91a and 91b and fall into the falling part 86. and.

When the discharge solenoids 92a and 92b are de-energized, the locking claws 91a and 91b are closed by the biasing force of the return spring.
returns to the original position shown in FIG. 12 (A>), and the five-ball blocking section prevents the pachinko balls in the flow regulation section 85 from flowing down.

The locking claws 91a, 91b are supported on the spindle 93 to freely swing, and each training stop part is formed in a fan shape that matches the swing locus, so each training stop part always moves in a tangential direction with respect to the pachinko ball. Therefore, when entering the flow regulating section 85, the pachinko ball inside the flow regulating section 85 is not bitten, and when retreating, there is no resistance due to the ball pressure of the pachinko ball that was preventing the ball from flowing down, and the ball is locked. Claws 91a and 91b are discharge solenoid 92a
.

It operates smoothly depending on whether 92b is turned on or off.

The ejection sensors 74a, 74b are composed of predetermined proximity switches having a structure surrounding a detection port 96 on all sides through which pachinko balls pass, and the ejection stopper mechanism 73a.

The locking claws 91a and 91b of 73b are the flow regulating portion 72a.

The bottom wall of the flow regulating section 85 of the flow regulating sections 72a and 72b is inserted into the flow regulating section 85 of the flow regulating sections 72a and 72b at a position that surrounds approximately the center of the second pachinko ball following the first one whose flow has been prevented from flowing downward. Insert the sensor base 98 into the storage section 97 formed on the side, and insert the sensor tip 100 into the recess 99 on the opposite side, and insert one side of the detection port 96 into the notch 101 of the projections 90a and 90b on the side wall of the flow regulating section 85. The detection port 96 and the other side 104 of the sensor are fitted into the recess 103 formed in the cover 77, 78, and are installed in parallel.

The four inner surfaces of the detection ports 96 of the discharge sensors 74a and 74b (
(excluding corners), the inner surface of the central base frame 7611 is continuous with the surfaces of the projections 90a and 90b, and the inner surfaces of the other three sides are continuous with the bottom wall, top wall of the flow regulating section 85, and side walls of the covers 77 and 78, respectively. However, the pachinko balls flowing down the flow regulating section 85 smoothly pass through the detection port 96. In order to detect successive pachinko balls, when discharging sensors 74a and 74b surrounding the detection port 96 are arranged in parallel on both discharging paths, a predetermined interval is required, but By increasing the distance between the two discharge passages, the discharge sensors 74a and 74b can be arranged side by side. Each discharge sensor 74a, 74b outputs an on signal when the pachinko ball is inside the detection port 96, including when the pachinko ball is passing through the detection port 96 of the sensor, and outputs an off signal when there is no pachinko ball.

In this way, the inflow gutter 71a, 71
Discharge sensors 74a and 74b are installed in parallel to both the flow regulation parts 1185 of the flow regulation parts 72a and 72b following b, and the inflow gutter 71
a, 71b to the flow regulating section 72a.

Band-shaped protrusions 90a, 90b that gradually rise are formed on the partition wall between both the discharge passages 72b, and these protrusions 90a, 90b
Since the distance between the sensor installation part, that is, the image flow part 85 is widened while gradually separating both the discharge passages through the inflow gutter 71a,
71b, flow regulating section 72a;

The discharge sensors 74a and 74b having a predetermined width can be easily arranged in parallel to the image flow section 85 while allowing the pachinko balls to flow down smoothly through the flow section 72b.

Furthermore, by forming band-shaped protrusions 90a and 90b that gradually rise on the partition wall between the two discharge passages, the interval between the sensor installation parts is widened.
There is no need to increase the thickness of the entire partition wall between 2b, and therefore manufacturing costs can be reduced.

On the other hand, at the inflow ends of the inflow gutter 71a, 71b connected to the passages 57a, 57b of the guide gutter 41, a band-shaped protrusion 90a
, 90b are equally continuous with the dividing wall 58 of the guide trough 41, so there is no need to separate the passages 57a and 57b of the guide trough 41 in two directions, which facilitates the production of the guide trough 41 and allows the guide trough 41 to be easily manufactured. Since the pachinko balls from the passages 57a, 57b of 41 smoothly flow into the inflow gutter 71a, 71b, the flow of pachinko balls may fluctuate when flowing in, and the guide gutter 41, inflow gutter 71a, 71b, etc. may be partially blocked. Can sufficiently prevent wear.

Furthermore, since there is no need to widen the distance between the passages 57a and 57b of the guide gutter 41, the dividing wall 58 can be set to an appropriate thickness, thereby ensuring that pachinko balls are properly placed in the passages 57a and 57b. The balls are distributed and aligned, and are guided to the inflow troughs 71a, 71b in an aligned state, thereby preventing the balls from overlapping or clogging the guide trough 41.

These ejection mechanisms 42a, 42b and ejection mechanism 42a,
To explain the movement of the pachinko balls inside 42b, the locking claws 91a, 91b of the ejection stopper mechanisms 73a, 73b enter the flow regulating parts 85 of the flow regulating parts 72a, 72b to prevent the pachinko balls from flowing down. In this state, the pachinko balls are lined up with the pachinko balls in contact with the locking claws 91a, 91b in the flow regulation parts 72a, 72b and the inflow troughs 71a, 71b without gaps, and are stationary. At this time, the ball pressure from the pachinko balls on the guide gutter 41 side is reduced by the first bent part 80 and the second bent part 82 of the inflow gutter 71a, 71b, and the flow regulating parts 72a, 7
2b side, and the discharge stopper mechanism 7
The ball pressure applied to the locking claws 91a, 91b of 3a, 73b is only applied to the pachinko balls in the flow regulating portions 85 and guiding portions 84 of the flow regulating portions 72a, 72b.

Then, when the discharge solenoids 92a and 92b of the discharge stopper mechanisms 73a and 73b are turned on and the locking claws 91a and 91b are retreated from inside the flow regulating section 85, the leading pachinko ball in the flow regulating section 85 and the following pachinko ball are removed. The pachinko balls in the flow section 85 and the guide section 84 quickly begin to flow down, and subsequently the pachinko balls in the vertical section 83 flow into the guide section 84 and are controlled in speed and spacing by the upper wall 89 of the guide section 84. Adjusted guiding part 8
4 and quickly flows down through the flow regulating section 85.

Furthermore, following this, the pachinko balls in the second H curved portions 82 of the inflow troughs 71a and 71b quickly flow into the vertical portion 83, and the pachinko balls in the inclined portion 81 flow into the second bent portion 82. The pachinko balls in the bent part 80 quickly flow into the inclined part 81, and the pachinko balls in the inclined part 79 reach the cover 7.
It quickly flows into the first bent part 80 while being displaced to the 7.78 side.

At this time, due to the retreat of the locking claws 91a and 91b, the leading pachinko ball and the pachinko balls in the flow regulating part 85 following the leading flow down inside the flow regulating part 85 while almost contacting each other, and the pachinko balls from the guiding part 84 Since the flow regulation part 85 continues at an angle of approximately 45 degrees, the flow regulation part 8 gradually separates from the pachinko ball in front while changing direction.
Since the speed and interval of the pachinko balls flowing down through the vertical section 83 are adjusted by the upper wall 89 of the guiding section 84, they flow down within the flow regulating section 85 at predetermined distances. In addition, the flow regulating part 85, the guiding part 84, the vertical part 83
, the bent part 82, the inclined part 81, etc., the ball pressure at each part is small, so the pachinko ball flows down smoothly.

Then, when the discharge solenoids 92a and 92b of the discharge stopper mechanisms 73a and 73b are turned off and the locking claws 91a and 91b enter the flow regulating section 85, the pachinko balls that are flowing down inside the flow regulating section 85 are stopped. The pachinko balls collide with the claws 91a and 91b and are prevented from flowing down, and subsequently the pachinko balls in the flow regulating part 85, the guiding part 84, the vertical part 83, the bent part 82, the inclined part 81, the bent part 80, and the inclined part 79 also It is stopped from flowing down and returns to its original stationary state. Since the ball blocking portions of the locking claws 91a and 91b coincide with the swing locus, the impact force caused by the collision of the pachinko balls is transferred to the support shaft 93.
This improves durability, and since the ball blocking part moves tangentially to the pachinko ball, even if it collides with the pachinko ball when the locking claws 91a, 91b enter the flow regulating part 85, A locking claw 91a that does not bite pachinko balls.

91b enters smoothly.

That is, the inflow gutter 71a, 71b of the discharge mechanism 42a, 42b following the guide gutter 41 is provided with two bent portions 80°82, and the vertical portion 83 is provided following the bent portion 82, and the lower side wall 88 of the vertical portion 83 is protruded. The guide section 84 with the upper wall 89 inclined is provided on the opposite side, and the discharge stopper mechanisms 73a and 73b are disposed in the flow regulation section 85 inclined at approximately 45 degrees below the guide section 84, so that the discharge solenoid 92a, Smooth flow of pachinko balls can be ensured when the solenoid 92b is turned on, and the locking claws 91a and 91 are secured when the discharge solenoids 92a and 92b are turned off.
It is possible to appropriately prevent pachinko balls from falling by reducing the ball pressure applied to b, etc., and reliability is greatly improved. Also,
The ejection mechanisms 42a and 42b have a unit structure,
Therefore, when each part breaks down, the entire unit can be easily replaced, allowing quick response to breakdowns, etc. In addition, since each solenoid is arranged vertically, it is possible to prevent dirt from entering the interior and the rods from becoming unbalanced.

The prize ball discharge gutter 43 following the discharge mechanisms 42a and 42b is a second
As shown in the figure, it consists of one system, and the discharge mechanisms 42a, 4
The flow regulating section is formed of an inflow section 105 connected to both falling sections 86 of flow regulating sections 72a and 72b of 2b, and an ejection section 107 provided with a downflow gutter 106 connected to the pachinko ball supply tray on the front surface of the base 2. The 6-distribution gutter 44, in which the pachinko balls flowing in from both the falling parts 86 of 72a and 72b hit a projecting wall etc., falls onto the gutter 106 and is discharged to the supply tray, is connected to the receiving tray at the lower front of the base 2, and is connected to the receiving tray at the lower front of the base 2. When it becomes full of pachinko balls, the pachinko balls overflowing from the downflow gutter 106 are discharged into a saucer. Further, the distribution gutter 44 is provided with a detection piece 108 that also serves as a gutter wall directly below the downflow gutter 106, and a switch (overflow switch) 109 that is linked to the detection piece 108, so that the inside of the distribution gutter 44 is filled with pachinko balls. When the detection piece 108 is pushed by the pressing force, the overflow switch 109 outputs an on signal.

The ball ejecting gutter 45 that branches from the middle of the prize ball ejecting gutter 43 has a plate-shaped ball ejecting gate 110 that can freely rotate via a spindle 111 at the branching part, as shown in FIGS. 13(A) and (B). arranged,
A crank 112 fixed to a support shaft 111 outside the gutter wall is engaged with a lever 113, and a ball ejecting gate 110 is attached to the rear end of the lever 113 in the closed position of the ball ejecting gutter 45 (the prize ball ejecting gutter 43 is open). A spring 114 is engaged with the lever 113, and a ball removal solenoid 116 that drives the ball removal gate 110 is connected to the lever 113 via a link 115 on the opposite side of the spring 114.

When the bulb removal solenoid 116 is energized, the link 115
Due to the upward movement, the ball extraction gate 110 is rotated against the spring 114 to a position where it opens the ball extraction gutter 45 and closes the prize ball ejection gutter 43, and when the ball extraction solenoid 116 is de-energized, the spring 114 The ball removal gate 110 is the ball removal gutter 45

16 is connected to the ground of the board 215, the induction gutter 4
1, static electricity is guided from the conductive plates 59a and 59b to the attenuator 61, where the energy is attenuated, and is further transferred to the control device 200 via the case 216 of the control device 200 and the ground of the board 215. It is released to the outside from the main power supply side.

For this reason, pachinko balls are equipped with prize ball sensors (ejection sensors,
This system reliably prevents sensors from being destroyed or malfunctioning due to electrostatic discharge from pachinko balls when they pass through safety sensors, etc.) and sensors on the game board 1 side (start switch, cycle switch, count switch, etc.). can. Further, since the static electricity released to the conductive plates 59a and 59b is attenuated by the attenuator 61, the board 215 of the control device 200 is not adversely affected by static electricity noise.

In addition, if the conductive plates 59a and 59b are connected to the frame side of the board 2 and the static electricity is absorbed by the frame and discharged naturally, it is necessary to connect the ground when there is a large amount of static electricity. In this way, the control device 20
Since it is discharged from the main power supply side of the main power source, static electricity can be reliably dissipated and high reliability can be obtained.

In addition, since static electricity is emitted from the main power supply side of the control device 200, noise absorption performance may differ depending on the structure of the control device, such as when static electricity is emitted from the control device side of the game board. There is no problem such as having to connect the conductive plates 59a and 59b every time the conductive plates 59a and 59b are replaced.

Next, the control contents by the control device 200 are shown in FIGS. 21 to 43.
This will be explained based on the flowcharts in FIGS. (A) to (C).

Figure 21 shows the main flow.
``Initialization processing'', ``background job to monitor each sensor, ``ball extraction processing'', prize ball ejection processing'', and ``
It consists of "improper processing of emissions" etc.

In the initialization process, the stack pointer is set as shown in Figure 22, the input/output ports of the CPU 201 are initialized, output to each device is turned off, the RAM is cleared, and the number of illegal monitoring balls is set. is the discharge 1 side in Figure 23,
This is set in the fraud monitoring counter on the second side.

During this process, the number of prize balls on the safe I side and the number of prize balls on the safe ■ side set by the prize ball number setting circuit 212 are read and stored in the RAM. After this process, the number of prize balls on the safe T side and the number of prize balls on the safe ■ side are read periodically and rewritten in the RAM.

The number of prize balls for the safe ■ side and the safe ■ side is determined by the prize ball number setting circuit 2.
By selecting a combination of the resistance values of the 12 resistors 213a, 213b, 214a to 214b, the selection can be made freely and easily, and therefore it is possible to set the number of prize balls that matches the model of the game board 1. . In addition, the prize ball number setting circuit 21
Since the number of prize balls of 2 is rewritten periodically in RAM,
Heat, static electricity, and other noise inside the pachinko machine are absorbed and shielded as described above, so they have little effect, but even if they destroy the data on the number of winning balls stored in the RAM, The number of prize balls can be immediately reset in the RAM. For this reason, when discharging prize balls based on the stored value of the number of prize balls in the RAM, there is no mistake in the number of prize balls, and high reliability is ensured.

Figure 24 shows a background job.

“Timer monitoring”, “Safe sensor monitoring”, “Emission sensor 1 monitoring”, “Emission sensor 2 monitoring” executed at regular intervals
The execution cycle is shown in Figure 25, and the timer is shown in Figure 26 and 2.
Updated and monitored as shown in Figure 7.

Safe sensor monitoring is performed by the flow regulating section 18 of the winning ball processing device 15.
The presence or absence of a pachinko ball (winning ball) is detected with high accuracy by a safe sensor between the two training stop parts of the stopper mechanism 20 provided in the flow regulating part 29 of the flow control part 29, and the signal of the safe sensor is When the safe sensor signal changes from off to on, it is determined that a ball is present when it remains on for 10 milliseconds. When the signal of the safe sensor turns off, it is determined that there is no ball when 4 milliseconds have elapsed since the signal was turned off.

In this safe sensor processing, if the change in the signal of the safe sensor is temporary, it is regarded as noise and is invalidated. The winning ball that entered the flow regulating section 29 of the flow regulating section 18 is stopped by the stopper mechanism 20
Since the ball is once prevented from flowing down, 10 msec is sufficient for the safe sensor to detect the presence of the ball. Thereby, the presence or absence of winning balls can be accurately detected.

The discharge sensor 1.2 monitors the discharge mechanism 42a (discharge 1 side)
, 42b (discharge 2 side) flow regulating section 72a.

The ejection sensor 1 upstream of the ejection stopper mechanism 73a, 73b removes the pachinko balls (prize balls) flowing down the flow regulating part 85 of the ejection stopper mechanism 73a, 73b.
．． 2 for accurate detection, and the 2nd
As shown in Figures 9, 30, and 31, detection (rise detection) is performed based on the previous and current signals of the exhaust sensors 1 and 2, that is, the signals of the exhaust sensors 1 and 2 change from OFF to ON (
Changing to previous time), if the signals of ejection sensors 1 and 2 are on this time, there is a ball, that is, the pachinko ball is ejection sensor 1.
It is determined that it is within 2. When the signals of emission sensors 1 and 2 changed to off (previously), the current emission sensors 1 and 2
If the signal is off, it is determined that there are no balls, that is, there are no pachinko balls in the discharge sensors 1 and 2.

FIGS. 44(A) and 44(B) show an example of the processing of the discharge sensor 1.2. In the case of frame 2 or 10, the sensor signal changes from off to on and then turns off again. The signal ON is regarded as noise and is invalidated. In the case of frame 5 or 13, after the sensor signal changes from off to on, the signal turns on again this time, so it is determined that there is a ball (rising) when the signal is input this time. frame 6
．． In the case of 7, it has been determined that there is a ball. In the case of frame 9, after the sensor signal changes from on to off, the signal turns off again this time, so it is determined that the current signal input is a fall without a ball. Due to the processing of the discharge sensors 1 and 2, the flow regulating section 72a.

72bf) The prize balls flowing down the flow regulating section 85 can be accurately detected, and the prize balls flowing down can be counted.

Further, in monitoring the discharge sensor 1.2, the counters on the discharge 1 side and the discharge 2 side are decremented by 1 when determining the rise. In addition, when the ejection stopper mechanisms 73a and 73b are preventing the pachinko balls from flowing down, the ejection sensor 1.2
Detect the second pachinko ball.

The ball removal sensor monitoring is to detect whether or not the ball removal sensor is turned on by operating the instrument inserted through the operation hole on the front surface of the base plate 2. As shown in Figure 32, the ball removal sensor signal is detected. When changing from off to on (previously), if the current ball removal sensor signal is on, it is determined that the ball removal sensor is on.0 If the ball removal sensor signal is off, the current ball removal sensor signal is If it is off, it is determined that the ball removal sensor is off.

In this way, it is possible to accurately detect the winning ball, the prize ball on the ejection mill [2 side, and the turning on of the ball removal sensor. In other words, the winning ball is determined from the state of the safe sensor signal for a certain period of time, and the ejection sensor 1
．． 2. The ball removal sensor detects the prize ball and sensor on by comparing the previous signal and the current signal, so it is possible to distinguish between the sensor signal and noise, and reliably prevents malfunctions of the control device 200 due to erroneous signals. can. In addition, this also makes it possible to reliably prevent fraudulent acts such as causing the prize ball ejecting device f16 etc. to malfunction due to the generation of noise by discharging electricity onto metal parts such as the metal bars of the pachinko machine using an electronic lighter or the like.

Safe ■ Signal processing is specific winning hole 304.3 of game board 1
When a winning ball is won in 05a or 305b, the number of winning balls is stored based on the safe ■ signal from the control device of the game board 1, and the winning ball number on the safe ■ side is selected.

Here, the operation of the control device of the game board 1 will be described.

Specific winning opening 304.3 as shown in Figure 45 (A) and (B)
When a prize is won in 05a or 305b, the number of contributions is stored and a safe ■ signal is output for 300 msec in synchronization with the call signal from the control device 200 in accordance with the memory.

After this output, the winning memory number is decremented by 1.

On the other hand, the control device 200
4. As shown in Figure 4, in order to adjust the timing of processing,
A call signal is output every m seconds, and when a safe ■ signal is received from the control device of the game board 1, when the signal continues for 10 m seconds, it is determined that a ball has entered the safe ■. When it is determined that there is a safe ball entering the ball, a call signal is output for 320 m seconds, and the safe n counter that stores the number of safe ball entering balls is incremented by 1. Thereafter, the call signal is turned off for 170 m seconds, and the call signal is output again every 50 m seconds.

Note that the next safe ■ signal will not be accepted until after the call signal has been output for 320 m seconds and turned off for 170 m seconds.

FIG. 46 shows a timing chart of safe ■ signal processing.By using the call signal in this way, signals can be sent and received accurately, and control can be performed accurately and easily.

Note that while the control device of Game III is suspended, the ready signal from the control device changes to "H" and safe ■ signal processing is not performed.

Then, when the safe sensor monitor detects that there is a prize ball, a prize ball ejection process is started. The prize ball discharge process is performed after confirming the prize ball discharge conditions as shown in Figure 35. Safe ■If there are no human balls, Safe! The number of prize balls on the side is set as the number of prize balls on the safe ■ side if there is an incoming ball, and the set number of prize balls is discharged, and after this discharge, the winning balls are discharged.

The prize ball ejection conditions are as shown in Figure 36, when 400 msec (ejection weight timer) has elapsed since the end of the previous ejection process, there is a winning ball, and the ejection sensors 1 and 2 continue to be in the ball presence state for 50 msec. To establish. In other words, there is a winning ball that was not in the previous ejecting process, was not in the process of ejecting winning balls, and the ejecting mechanism 42
There are prize balls in the flow control gutter 72a, 72b of a, 42b,
If there is no error, it is OK to start discharging.

The prize ball set is shown in Figures 37 and 38 (A).

In (B), select the ejection method that matches the number of prize balls and start ejecting the prize balls. In other words, in the case of the number of prize balls on the safe I side (10 to 15), and even in the case of the safe ■ side, when the number of prize balls is 9 or more, the number of prize balls is divided (approximately in half) and divided. Set the number of prize balls you have scored on the counters on the 1st and 2nd side of the discharge,
Both ejection mechanisms 42a.

When the number of prize balls is 8 or less in the case of the safe ■ side where combined discharge is performed from 42b, the number of prize balls is set alternately on the counters on the discharge 1 side and 2 side, and the discharge mechanisms 42a and 42b
If the number of prize balls is one,
Discharge one piece in the same way.

At this time, the corresponding discharges 5 oil and 2 are turned on.

In addition, in the case of combined discharge and alternate discharge, the set value of the counter is set to a value that has been decremented by -1 in advance.

When the prize ball discharge starts, each time the discharge sensors 1 and 2 detect the rise of the falling prize balls, the counters on the discharge 1 side and 2 side are decremented by 1, and the counters on the discharge 1 side and 2 side are decremented by 1, and When the counters on the ejection 1 and 2 sides reach "0", the ejection of prize balls on the ejection mechanisms 42a and 42b ends, and the corresponding ejection 5o11.2 is turned off. In this case, even if 3 seconds have elapsed since the start of prize ball ejection, the counters on the ejection 1 and 2 sides will continue to display “
If it does not become 0'', after turning off the discharge 5o11.2, the discharge error process begins (described later).

Here, single discharge, alternate discharge, and combined discharge will be explained.

One ball is ejected (number of prize balls "1") by the ejection mechanism 42a.

The prize ball III is selectively ejected from either of the balls 42b and 42b, as shown in the timing chart of FIG.
When the discharge start is OK, turn on the discharge 5011 of one of the discharge mechanisms 42a and 42b, and turn off the discharge 5011 after 35 m seconds.0 When performing III discharge next, it is OK to start the discharge again.
And the ejection mechanism 42a.

The other discharge 5o12 of 42b is turned on, and after 35 m seconds, the discharge 5o12 is turned off. In addition, depending on whether the discharge sensors 5o11 and 2 are turned on or off, the discharge sensor 1.degree.2 is automatically turned off and then turned on.

When the discharge 5 oil or 2 is turned on, the locking claw 91a or 91b of the discharge stopper mechanism 73a or 73b retreats from within the corresponding flow regulating section 85, and the locking claw 91a* or 91
The pachinko ball, which was prevented from flowing down by b, is released,
Due to this release, the first ball in the corresponding flow regulation section 85 falls into the prize ball discharge gutter 43, and the second and subsequent balls then start flowing down, but when the discharge 5oil or 2 is turned off after 35 m seconds. Immediately after the second ball starts flowing down, the locking pawl 91a or 91b enters the corresponding flow regulating section 85, and the second and subsequent balls are prevented from flowing down by the locking pawl 91a or 91b (the second ball is prevented from flowing down). 12 (A) and (B)), one prize ball is thereby ejected.

In the case of one discharge, if discharge 5o11.2 (selected side) is turned on and then discharge 5o11.2 is turned off by detecting the rising edge of discharge sensor 1.2, the detection position of discharge sensors 1 and 2 (flowing down) (detecting the second ball following the first ball while the first ball is blocked), two balls are ejected, so 1
If it is impossible to discharge the air, and if the falling of the discharge sensors 1 and 2 is detected and the discharge 5o11.2 is turned off, the flow regulating part 8
If you do not make the slope of 5 vertical to slow down the velocity of the ball, the turn off of the discharge 5o11.2 will be delayed, so it is impossible to discharge just one, but it is possible to turn on the discharge 5o11.2 for a specified time like this. In other words, by controlling the time, one prize ball can be ejected accurately. Note that if the slope of the flow regulating section 85 is made gentler to slow down the falling speed of the balls, the ejection time and processing time will become longer in alternate ejection or combined ejection with a large number of prize balls, which is unsuitable.

Alternate discharge (number of prize balls “2” to “8”) is “2°” of the number of prize balls.
The prize balls corresponding to ~ "8" are selectively ejected from either the ejection mechanism 42a or 42b, and as shown in the timing chart of FIG. 48 (when the number of prize balls is 3),
When the discharge start is OK, the discharge 5oil of one of the discharge mechanisms 42a and 42b is turned on, and as a result of this turning on, the locking claw 91a retreats and the pachinko ball starts flowing down from the corresponding flow regulating part 85.
Along with this, the discharge sensor 1 detects the rise of the falling pachinko balls, and when the rise is detected a predetermined number of times (number of prize balls - 1), the discharge 5 oil is turned off. In addition, when performing alternate discharge next time, it is OK to start discharge again, and the discharge mechanisms 42a, 42
The other discharge So+2 of b is turned on, and similarly the pachinko balls start flowing down from the corresponding flow regulation part 85, the discharge sensor 2 detects the rise of the falling pachinko balls, and repeats the rise a predetermined number of times (number of prize balls - 1) When detected, turn off the discharge 5o12.

That is, when the discharge 5 oil or 2 is turned on, the locking claw 91
a or 91b retreats, and the leading pachinko ball is moved from the corresponding flow regulating section 85 to the upstream of the flow regulating section 85 and the guiding section 8.
The subsequent area starts flowing down from the 4 side, and these balls fall into the prize ball discharge gutter 43 in order from the first ball. Count. At this time, depending on the position of the discharge sensor 1.2, the first ball and the second ball in the flow regulating section 85 are not counted, but the third ball is counted. Then, eject the pachinko ball to the corresponding side 1 or 21.
Count the set value of counter 1 and discharge 5ol.
When l or 2 is turned off, the balls counted last time fall into the prize ball discharge gutter 43 before the corresponding locking pawl 91a or 91b enters the flow regulation section 85, and the balls counted at the current time and the subsequent area are prevented from flowing down by the corresponding locking claws 91a or 91b that have entered the flow regulating portion 85 (see FIGS. 12(A) and 12(B)).
In addition to the th ball, prize balls equal to the count plus 1 are ejected. In the case of FIG. 48, the count is 2 and 3 prize balls are ejected.

In this way, in alternate discharge, by counting the number of pachinko balls minus one from the number of prize balls and turning off the discharge Sol, it is possible to accurately discharge the prize balls corresponding to the number of prize balls.

Note that while the discharge 5o11.2 (selected side) is on, the first ball and the second ball of the flow regulating section 85 flow down the flow regulating section 85 while almost touching each other, and the third and subsequent balls from the guiding section 84 flow down the flow regulating section 85. is about 4
Since the flow regulation part 85 continues at an angle of 5 degrees, the flow flows down the flow regulation part 85 while changing the direction and gradually 111JIJfl with the ball in front, and furthermore, the trailing area from the vertical part 83 flows into the upper wall 8 of the guiding part 84.
Since the speed and interval are adjusted by 9, the water flows down the flow adjustment section 85 at a predetermined distance. For this reason, the emission 5o
When Ill, 2 is turned off, it becomes easier for the locking claws 91a, 91b to enter the flow regulating section 85 as the number of prize balls increases, but even when the number of prize balls is two, the locking claws 91a, 91b is easy to enter.

In addition, for single discharge and alternate discharge, two
It is selected whether the prize balls are to be discharged from either of the system discharge mechanisms 42a and 42b. In other words, 1 depending on the winning ball.
When discharging pieces is performed continuously, for example, for the first winning, the discharging is performed by the discharging mechanism 42a side, and for the next winning, discharging is performed by the discharging mechanism 42b side (47th prize).
), similarly, when alternate discharge is performed continuously, for example, for the first winning, the discharging is performed by the discharging mechanism 42all, and for the next winning, discharging is performed by the discharging mechanism 42b side. (See FIG. 48). Also, when single piece ejection and alternate ejection are performed consecutively, for example, if one piece ejection is first performed on the ejection mechanism 42a side, then the next alternate ejection is performed on the ejection mechanism 42a side.
This is done on the b side.

In this way, since the two systems of ejection mechanisms 42a and 42b are used alternately to eject the prize balls, it is possible to prevent the balls from flowing unbalancedly in the guide gutter 41, etc., resulting in clogging of the balls, etc. Maintains smooth ejection of balls. In addition, even if only one ejection or alternate ejection is used depending on the setting of the number of prize balls, the ejection mechanism 42a,
42b are used alternately.

Combined discharge (number of prize balls “9” or more) is the number of prize balls “9” to “
The prize balls corresponding to 152 are ejected from both ejection mechanisms 42a and 42b, and as shown in the timing chart of FIG. 49 (when the number of prize balls is 10 and 15), it is OK to start ejecting, Ejection 5o1 of both ejection mechanisms 42a and 42b
1.2 is turned on, and the locking claws 91a, 9 are turned on.
1b retreats and the pachinko balls begin to flow down from the image control flow section 85, and along with this, the discharge sensors 1 and 2 detect the rise of the falling pachinko balls. Then, when each discharge sensor 1.2 detects the rise a predetermined number of times (divided number of prize balls - 1), in this case, when the number of prize balls is 10, the discharge ill counter set value = 4 causes the discharge sensor 1 to 4 times, discharge 2
When the discharge sensor 2 detects four rises due to the set value of the side counter = 4, the corresponding discharge 5o11.2 is turned off. In addition, when the number of prize balls is 15, the set value of the discharge 1 tsuba counter = 7, so the discharge sensor 1 is activated 7 times, and the discharge 2 is activated 7 times.
When the discharge sensor 2 detects six rises due to the set value of the side counter: 6, the corresponding discharges 5oi1 and 2 are turned off, respectively.

That is, by turning on both discharges 5o11.2, the locking claw 91a
, 91b move back, and the leading pachinko balls and subsequent acid begin to flow down from the flow regulating section 85, and these balls fall into the prize ball discharge gutter 43 in order from the leading ball.
Accordingly, from the detection of the rise of the pachinko balls by the discharge sensor 1.2, the pachinko balls flowing down the flow regulating section 85 are
By counting the set value of the corresponding discharge 1 side and 2 side counters and turning off the corresponding discharges 5 oil and 2, respectively,
Prize balls whose number is +1 to the set value of the discharge 1-counter are discharged from the flow regulation section 85 of the discharge mechanism 42all, and prize balls whose number is +1 to the set value of the discharge 2 side counter are discharged from the flow regulation section 85 of the discharge mechanism 42b side. The ball is ejected. At this time, depending on the positions of the discharge sensors 1 and 2, the first ball and the second ball in the flow regulating section 81 are not counted, but are counted starting from the third ball, and the ball and the subsequent acid at the final count are The flow is prevented by turning off the discharge 5 oil and 2. As a result, as shown in FIG. 49, when the number of prize balls is 10, five prize balls are discharged from the flow regulation parts 85 of both discharge mechanisms 42a and 42b, and when the number of prize balls is 15, they are discharged. Eight prize balls are discharged from the flow regulating section 85 of the mechanism 42a, and seven prize balls are discharged from the flow regulating section 85 of the discharging mechanism 42b.

In this way, in combined ejection, the number of prize balls is divided and the number of pachinko balls that are subtracted by 1 from the number of prize balls after division is counted, and the number of prize balls corresponding to the number of prize balls is can be discharged properly. In addition, when the number of prize balls is large, both ejection mechanisms 42a and 42b are used for combined ejection.
Since the prize ball is ejected using a , the ejection time can be shortened. In addition, in the case of combined discharge, the vertical part 8 upstream of the guiding part 84
Since the balls from 3 onwards flow down the flow regulation part 85 and the distance between the balls is large, the discharge 5 oil and 2 are turned off, so of course it is easy for the locking claws 91a and 91b to enter into the flow regulation part 85. .

By the way, if a ball jam occurs during these ejection processes, the specified number of prize balls may not be ejected. For this reason, the 39th f! The corresponding discharge 1 side from the start of discharge at l,
If 3 seconds (ejection monitoring timer) elapse before the value of the counter on the second side reaches O", it is determined that there is an ejection error due to ball clogging, and ejection 5o11.2 is turned off.

That is, it is possible to accurately detect a discharge error due to a clogged bulb from the value of the counter of the corresponding discharge I11.281 after a predetermined period of time has elapsed, and in this case, the clogged bulb can be corrected while maintaining the discharge 5o11.2 in the OFF state. It turns out.

On the other hand, if a ball jam occurs and the values of the counters on the corresponding ejection 1 and 2 sides are "1", the last pachinko ball is not counted, but the previous pachinko ball is also ejected. In this case, a specified number of prize balls will be ejected.

After correcting the clogged bulb, the discharge sensor 1.2
The recovery from the ejection error occurs when the ball continues for 3 seconds. After this return, the number of prize balls before the error is reset to the corresponding discharge 1 side, 2111 counter, and the discharge process is started again. If the values of the corresponding discharge 1 side and 2 side counters are "1", the prescribed number of prize balls will be discharged, and the discharge process will be completed.

Fig. 50 shows a timing chart after an ejection error and recovery (when the number of prize balls due to combined ejection is 10).
A discharge monitoring timer (3 seconds) starts at the same time as discharge 5 oil and 2 are turned on, and for example, when the discharge sensor 2 side counts a specified number of pachinko balls, discharge 5 and 12 are turned off.
If the discharge monitoring timer times up before the prescribed number of pachinko balls are counted on the discharge sensor 1 side, it is determined that a discharge error has occurred, and the discharge 5 oil is turned off at the same time as the time is up, and the system waits for recovery. After the recovery is completed, the discharge start condition is determined when the corresponding sensor 1 continues to be on for the period of the discharge monitoring timer (3 seconds), and if it is OK, the predetermined number of prize balls were not discharged last time. , perform the ejection process again with the same number of prize balls.

In particular, even if an error occurs like this, by performing the ejection process again with the same number of prize balls after recovery, the prescribed prize balls will always be ejected for each winning prize, and this will prevent players from using the prize balls. You can prevent troubles with.

In addition, if the prize ball is ejected when the prize ball is not being ejected and the locking claws 91a and 91b are retracted from the flow regulating part 85 due to a malfunction of the ejector 5011 or 2, etc., then the prize ball is ejected illegally. Error processing is performed using a monitoring counter (described later).

When the discharge process is completed, the safe Sol of the stopper mechanism 20 is turned on in FIG. 41.

At the same time, set the ejection weight timer (400 msec) and the safe bulb ejection monitoring timer (200 msec).

By turning on this safe Sol, the flow regulating section 2 of the flow regulating section 18
When the winning balls within 9 are ejected and the safe sensor determines that there are no balls, the safe Sol is turned off after 100 m seconds in FIG. 42, and the winning ball ejection ends. If the prize ball is ejected by the prize ball on the safe side, the safe side counter will be set to − at the end of the game.
Do 1.

FIG. 51 shows a timing chart of the seven-ball ejection process. Simultaneously with the end of the prize ball ejection process, the seven-f Sol of the stopper mechanism 20 is turned on, and this turns on the locking pawl 33 to respond. When the winning ball is released from the flow control section 29 and discharged to the outlet gutter 19.

Ejection of the winning ball is confirmed by the safe sensor being off for 4 msec, and the safe Sol is turned off 100 msec later.

Since safe ball ejection is performed upon completion of the prize ball ejection process, if a predetermined prize ball is not ejected due to the above-mentioned error or the like during the prize ball ejection process, the winning ball will be prevented from flowing down by the corresponding locking pawl 33. The condition remains as it is, and the lead-out gutter 19
In addition, when the safe Sol is turned on, the locking claw 33 retreats, while the locking claw 34 on the upstream side
enters the flow regulating section 29, and when the safe Sol is turned off, the locking pawl 34 retreats, while the locking pawl 33 enters the flow regulating section 29 (see Fig. 3(A), (Ba#)). .

Therefore, when there is a subsequent winning ball in the flow regulating section 29,
The subsequent winning ball replaces the previous winning ball by turning off the safe Sol, and is prevented from flowing down by the locking pawl 33.

In this way, the safe ball is ejected, but the safe S.

If the safe ball ejection monitoring timer (200 msec) times up while the safe sensor still has a winning ball after l is turned on, an ejection error is determined.

In this case, an ejection error occurs when the locking pawl 33 does not retreat from the flow regulating part 29 due to a failure of the safe sensor, etc., or when the safe sensor fails while in the ON state, but these are caused by the safe bulb ejection monitoring timer. This can be detected from the state of the safe sensor after a predetermined period of time has elapsed.

If there is a discharge error, the ball extraction gutter 45
ol is turned on and the ball remains in a stop state until the safe sensor detects that there is no ball. That is, when the ball extraction Sol is turned on, prize balls of the prize ball type are collected from the ball extraction gutter 45, and in this state, the malfunctioning parts of the safe Sol, the safe sensor, etc. are repaired. After recovery, when the safe sensor detects the absence of a ball, the safe Sol and ball removal Sol are returned to the OFF state in FIG. 42.

Fig. 52 shows a timing chart for safe ball ejection error processing. The safe ball ejection monitoring timer (200 msec) starts at the same time as safe Sol is turned on, and the safe sensor does not detect no ball until the time is up and remains on. If so, it is determined that there is an ejection error and the bulb removal Sol is turned on.
Waiting for recovery. If the recovery is completed and the safe sensor detects that there is no ball, the safe Sol and the ball-less Sol
Turn off and end error handling.

In other words, it is possible to accurately detect safe bulb ejection errors, and
Since the system enters a standby state in the event of an ejection error, it is possible to prevent the ejection process from entering the ejection process with the safe Sol or the safe sensor in a malfunctioning state, and it is possible to reliably prevent prize balls from being ejected due to malfunction.

It should be noted that each time the prize ball discharge is completed, a fraud monitoring counter is set and fraud monitoring is performed. In other words, if a prize ball is ejected from the ejection mechanism 42a, 42b while the prize ball is being ejected outside the device, if the fraud monitoring counter on the ejection 1 side and example 2 counts 5 prize balls, a fraud error will occur. is determined, and the ball extraction Sol is turned on in FIG. 21, resulting in a stop state.

Even though the prize balls are not being ejected and there are no winning balls,
If the prize ball is ejected due to some abnormality, if the prize ball is ejected immediately after the ejection of the prize ball, or if the prize ball is ejected due to some abnormality during the safe ball ejection process, etc. , a fraud error is determined based on the count value of the fraud monitoring counter.

Improper discharge may occur if the locking claws 91a or 91b of the discharge stopper mechanisms 73a or 73b remain retracted from the flow regulating section 85 due to a malfunction in the discharge stopper mechanism 73a or 73b, or if the locking claws 91a or 91b of the discharge stopper mechanisms 73a or 73b remain retracted from the flow regulating section 85 due to a malfunction in the discharge stopper mechanism 73a or 73b. The prize ball may be ejected if the ball or 91b is forcibly moved to the retreat position, but since the ejection of the prize ball is constantly monitored, if there is any irregularity in ejection, we will promptly correct the irregularity. Can be detected. Moreover, since the ball extraction Sol is turned on when fraud is detected, the prize balls are collected from the ball extraction gutter 45, and it is possible to prevent the prize balls from being discharged to the supply tray side.

In this state, recovery from malfunction or fraud is performed, and after recovery, the reset switch (14th r14,
(see FIG. 15), the ball extraction Sol is turned off, the fraud monitoring process is completed, and restarted.

Fig. 53 shows a timing chart of the fraud monitoring process. When the discharge process is not in progress, for example, if the movement of the ball is detected by the discharge sensor 1, the fraud monitoring counter on the discharge 1 side is set each time the ball rises. +1 and the counter becomes “5”
At the same time, the ball removal Sol is turned on and the system waits for recovery. Then, when the recovery is completed and the reset switch is turned on, the counter is cleared, the ball extraction Sol is turned off, and the process ends.

In this way, it is possible to accurately detect improper ejection due to a malfunction of the ejector 5o11.2, fraudulent activity, etc., and in the event of an incorrect ejection, the prize ball is collected from the ball ejecting gutter 45 by the ball ejecting Sol, and ejection is immediately stopped. Because it is in standby mode, discharge 5
o11.2, etc., and prevents fraudulent activities.

Figures 43 (A) to (C) show the ball removal process, and the ball removal process is a zero ball removal process that is performed when the game machine is discontinued, when the game parlor is closed, and when each device breaks down or is inspected. This is not possible when there are winning balls, when the winning balls are being ejected, and when each error is being processed.

When a device such as a pin is inserted through the operation hole on the front of the base 2 and the ball removal sensor is turned on (based on ball removal sensor monitoring), the ball removal Sol is turned on and when the ball removal start timer (1 second) has elapsed. , both discharges 5o11.2 of the discharge stopper mechanisms 73a and 73b are turned on.

When the ball removal Sol is turned on, the ball removal gate 110 provided at the branch part of the ball removal gutter 45 is opened, and the ball removal gate 11 is opened.
In order to prevent the ball from being ejected while the ball is being opened, the ejection valves 5oll and 2 are turned on after the elapse of the ball ejection start timer (1 second), and the locking claws 91a and 91b are retracted from the flow regulating section 85.

As a result, the prize balls in the upper tank 40 of the prize ball ejecting device 16 as well as the prize balls in the guide gutter 41 and the ejection mechanisms 42a and 42b flow down from the prize ball ejecting gutter 43 to the ball ejecting gutter 45, which is located at the rear of the pachinko machine. It is discharged and collected into a collection gutter (not shown).

And upper tank 405. Induction gutter 41, discharge mechanism 42a
, 42b is discharged to the collection gutter, and the prize ball in the discharge senna 1
．． When 2 is turned off, a timer (3 seconds) with no ejection of 1 or 2 balls is set, and after this timer elapses, ejection 5o11.2 is turned off, and then ball ejection S is performed.

Turn off l. At this time, even if the discharge sensors 1 and 2 are turned off, if the remaining balls in the upper tank 40 etc. are delayed and flow down and the discharge sensors 1 and 2 are turned on, the corresponding discharge 1. The 2-ball no-ball timer is reset, and after this timer elapses, 5 oil is discharged.

2. Turn off the ball removal Sol.

As a result, all prize balls are ejected and collected, and
After the discharge sensor 1.2 remains off for 3 seconds, the locking claws 91a and 91b return to the flow regulating section 85, and the ball removal gate 110 moves the ball removal gutter 45 to the closed position (the prize ball ejection gutter 43 is open).
It will return to , and it will end automatically. Note that if there are no recovered balls, the process will automatically end when the ball extraction start timer elapses.

Fig. 54 shows the timing chart of the ball removal process.
When the ball removal sensor turns on, the ball removal SOl is turned on,
One second later, by turning on discharge 5 oil and 2, ball removal is started. When the bulb removal is completed, when the discharge sensors 1 and 2 are off for 3 seconds, the discharge 5 oil and 2 oil are discharged.
．． S without ball.

1 is turned off and the process ends.

In this way, by turning on the ball removal sensor, balls can be removed, and all prize balls are ejected and collected, and the ejection sensor 1.
2 turns off for 3 seconds, discharge S.

11.2. The locking claws 91a, 9 are turned off by turning off the ball extractor Sol.
1b. Since the ball extraction gate 110 returns to its original position and the operation ends automatically, there is no need for any confirmation or operation when the ball extraction is completed, making the work easier.

In addition, if you want to forcibly stop the ball removal process in the middle of the ball removal process, you can force the ball removal process by inserting a device such as a pin again through the operation hole of the base 2 and turning on the ball removal sensor again. It will end.

That is, when the ball removal sensor is turned on after the ball removal Sol is turned on, a forced termination timer (1 second) is set in FIG. 43 (B), and if the prize ball is being collected, the ejection sensors 1 and 2 At the same time as detecting the rise of , the corresponding ejection 5o11.2 is turned off, and if the collection of prize balls has been completed, the ejection 5o11.2 is turned off when the forced termination timer elapses. and,
After the ball removal end timer (3 seconds) has elapsed, the ball removal Sol is turned off.

As a result, the locking claws 91a and 91b return to the flow regulating section 85, and the ball removal gate 110 returns to the closed position of the ball removal gutter 45, resulting in a forced termination.

Fig. 55 shows a timing chart for forced termination of the ball extraction process (when the ejection 1 side is collecting prize balls and the ejection 2 side has collected the prize balls). On the discharge 2 side, the discharge 5o12 is turned off after 1 second, and on the discharge 1 side, the discharge 5oil is turned off when the discharge sensor 1 detects the rising of the ball, and 3 seconds after that, the bulb removal Sol is turned off.

In this forced termination, when the prize ball is being collected, the ball whose rise was detected and the following ball return to the locking claw 91a into the flow regulating section 85.
, 91b, the flow is easily prevented from flowing down.

(Effect of the invention) As described above, according to the present invention, the prize balls in the storage tank are
A prize ball for a pachinko machine in which a guide gutter is formed to rectify and guide the ball in a row, and a discharge mechanism for discharging prize balls and a sensor for detecting prize balls are arranged in two parallel discharge paths following both rows of the guide gutter. In the discharge device, a band-shaped protrusion that gradually rises toward the sensor from the inlet portion or the middle of the discharge passage is formed on the partition wall between the two discharge passages, and the distance between the two discharge passages at the sensor position is widened, so that the structure is improved. Sensors can be placed in both discharge channels without complicating the process, and the prize ball can smoothly flow into the discharge channel while maintaining good alignment in the guide channel, and the prize ball can smoothly flow down the discharge channel. Therefore, it is possible to fully respond to electronic control, and to ensure high reliability as a prize ball ejecting device.
