Description

Description: BACKGROUND OF THE INVENTION (Industrial application field) The present invention relates to a ball-and-ball game machine, and in particular, has means for detecting a winning ball that has won a specific winning area, and detects all flowing-off winning balls. The present invention relates to a ball game machine that operates a ball discharging device based on a detection signal sent from a winning ball detecting means.

(Prior Art) Recently, many pachinko machines have a variable prize device that generates a special game or the like having a large prize rate depending on game conditions and provides a large number of prize balls to a player.

This kind of pachinko machine generates prize balls one after another when a special game occurs, and continuously discharges a large amount of prize balls in accordance with the prize balls. Therefore, as a device for processing a large number of winning balls and prize balls at high speed, an electronically controlled device has been proposed instead of a conventional mechanical device.

For example, in order to speed up the prize ball processing, while detecting a winning ball and a prize ball using an electric sensor,
Providing a flow-stopping member (stopper member) and an electric drive source capable of entering the passages in the processing path of the winning ball and the discharge path of the prize ball, respectively, and allowing the flow-down blocking member to enter and retreat based on the detection of the sensor. Then, it is considered to perform prize ball processing.

The electronically controlled type has a simple structure compared to the mechanical type using the weight of a conventional safe ball, as well as the speed of discharging the prize balls, as well as the control of the number of prize balls. There is an advantage that it is easy.

(Problems to be Solved by the Invention) In such an electronically controlled type, it is easy to control, but unlike the mechanical type, there is a problem of when to process a signal related to the number of prize balls. Occurs.

That is, in the case of the mechanical type, the winning balls continuously winning are simply stored, and the winning balls are processed one by one according to the timing at which the winning balls are processed, that is, the mechanical performance possessed by the winning balls. Since it is only the timing, the winning ball is naturally processed at the same timing. However, in the case of the electronically controlled type, various processing timings are possible due to its nature, It is most effective to process the related signals, and there arises a problem that there is no error in the control.

In the case of the electronically controlled type, since the ejection of the ball is controlled only by the input / output state of the signal, the response delay caused by the mechanical part related to the ejection of the ball by the control is a component. Also, even if the component is not actually operating, there is a risk that it is judged that the component is also operating just because there is a signal input, so if signals are input one after another, However, there is a fear that the operation of the mechanical part cannot catch up and cause a malfunction.

An object of the present invention is to solve the above-mentioned problems.

(Means for Solving the Problems) The present invention relates to a special prize detecting means (for example, start switches 308, 309a, 309b) for detecting a prize ball which has won a specific prize area provided on a game board, and A prize ball detecting means (for example, a safe sensor 21) for detecting all the prize balls which have flown and flow down to the prize area including the prize ball and outputting a detection signal, and operating a ball discharge device based on the detection signal. In a ball-and-ball game machine capable of discharging a required number of balls, a game control circuit (for example, a game board 1) for electrically controlling game-related control including detection processing of the specific winning detection means.
And a discharge control circuit (for example, the control device 20) that electrically controls the discharge operation of the ball discharge device.
0), the game control circuit stores the detection signal from the specific prize detecting means, and a predetermined number of prize balls based on the two detection signals from the specific prize detecting means and the prize ball detecting means. (For example, a safe II signal) is output to the discharge control circuit for a predetermined time so that the discharge control circuit can recognize the signal, and the stored detection signal of the specific winning detection means is decremented by one. The discharge control circuit is configured to prohibit the input of the signal related to the number of winning balls for a predetermined time after the signal related to the number of winning balls is input.

(Operation) Therefore, the detection signal of the specific prize detecting means is stored by the game control circuit, and a signal relating to a predetermined number of prize balls is output to the discharge control circuit based on the detection signals of the specific prize detecting means and the prize ball detecting means. Is output. Then, the detection signal of the specific winning detection means stored by the game control circuit is decremented by one.

Further, the input of the signal relating to the number of prize balls for a predetermined time after the signal relating to the number of prize balls is input by the discharge control circuit is prohibited. As a result, malfunction of the discharge control circuit can be prevented.

In the state of entering the flow control portion 85 of the 72b, the bottom wall of the flow control portion 85 of the flow control gutters 72a, 72b is provided at a position surrounding substantially the center of the second pachinko ball following the head, which has been prevented from flowing down. The sensor base 98 is inserted into the storage portion 97 formed on the side, the sensor tip portion 100 is inserted into the concave portion 99 on the opposite side, and one side of the detection port 96 is formed in the cutout portion 101 of the protrusion 90a, 90b on the side wall of the flow regulating portion 85. Side of
The detection hole 96 and the other side portion 104 of the sensor are fitted in the concave portion 103 formed in the covers 77 and 78, and are installed in parallel.

Of the four inner surfaces (excluding the corners) of the detection ports 96 of the discharge sensors 74a and 74b, the inner surface on the side of the central base frame 76 is on the surface of the projections 90a and 90b, and the other three inner surfaces are the flow regulating portions 85, respectively. The pachinko ball flowing down the flow regulating section 85 and continuing from the bottom wall, the upper wall, and the side walls of the covers 77 and 78 smoothly passes through the detection port 96. In order to detect continuous pachinko balls, when the discharge sensors 74a, 74b surrounding the detection port 96 are arranged side by side in both discharge paths, a predetermined interval is required, but through the protrusions 90a, 90b. By increasing the distance between both discharge paths, the discharge sensors 74a, 74
b can be installed side by side. Each of the discharge sensors 74a and 74b has a detection port including when the pachinko ball is passing through the detection port 96 of the sensor.
When it is within 96, an on signal is output, and when it is not 96, an off signal is output.

As described above, the discharge sensors 74a and 74b are arranged in parallel in the discharge paths, that is, in the two flow control portions 85 of the flow control gutters 72a and 72b following the inflow gutters 71a and 71b. Strip-shaped projections 90a, 90 gradually rising on the partition wall between the drainage channels 72a, 72b.
b, and the distance between the sensor installation part, that is, both flow control parts 85, is increased while gradually separating the two discharge paths via the protrusions 90a, 90b, so that the inflow gutters 71a, 71b and the flow control gutters 72a, 72b are formed. The discharge sensors 74a and 74b having a predetermined width can be easily arranged in parallel with the two flow regulating portions 85 while allowing the pachinko balls to smoothly flow down.

Also, since the interval between the sensor installation portions is widened by forming band-shaped projections 90a, 90b gradually rising on the partition wall between the two discharge passages, the entirety between the inflow gutters 71a, 71b and the flow control gutters 72a, 72b is increased. It is not necessary to increase the thickness of the partition walls, so that the manufacturing cost can be reduced.

On the other hand, the inflow gutters 71a, 71 connected to the passages 57a, 57b of the guiding gutter 41
At the inflow end of 1b, the strip-shaped projections 90a, 90b are equally continuous with the flow dividing wall 58 of the guiding gutter 41, so that the passages 57a, 57 of the guiding gutter 41 are formed.
b does not need to be formed separately in two directions.
1 and the pachinko balls from the passages 57a and 57b of the guiding gutter 41 smoothly flow into the inflow gutters 71a and 71b. And the inflow gutters 71a, 71b can be sufficiently prevented from being partially worn.

In addition, since it is not necessary to increase the interval between the two passages 57a and 57b of the guide gutter 41, the dividing wall 58 can be set to an appropriate thickness, and thereby the pachinko balls can be accurately placed in both the passages 57a and 57b. In addition to being distributed and aligned, it is possible to prevent the balls from being guided by the inflow gutters 71a and 71b in the aligned state and overlapping or clogging the balls in the guidance gutter 41.

The movement of the pachinko balls in the discharge mechanisms 42a and 42b and the discharge mechanisms 42a and 42b will be described.
In a state in which the locking claws 91a, 91b of b enter the flow adjusting portion 85 of the flow control gutters 72a, 72b to prevent the pachinko ball from flowing down, the locking claw is
With the pachinko balls in contact with 91a and 91b at the head, the pachinko balls are aligned without gaps in the flow control gutters 72a and 72b and the inflow gutters 71a and 71b,
It is stationary. At this time, the ball pressure from the pachinko ball on the guide gutter 41 side is applied to the first bent portion 80 and the second bent portion 8 of the inflow gutters 71a, 71b.
2, and does not reach the flow control gutters 72a, 72b. Further, the ball pressure applied to the locking claws 91a, 91b of the discharge stopper mechanisms 73a, 73b is set in the flow adjusting part 85 of the flow adjusting gutters 72a, 72b and the guiding part 8a.
Only the pachinko balls in 4 are available.

Then, the discharge solenoid 9 of the discharge stopper mechanism 73a, 73b
When 2a and 92b are turned on and the locking claws 91a and 91b are retracted from the inside of the flow adjusting portion 85, the head pachinko ball in the flow adjusting portion 85, the flow adjusting portion 85 following the head, and the pachinko ball in the guiding portion 84 Begins to flow down quickly, followed by the pachinko balls in the vertical section 83
After flowing into the guide portion 84, the speed and the interval are adjusted by the upper wall 89 of the guide portion 84, the guide portion 84 falls in the guide portion 84, and quickly flows down in the flow regulating portion 85. Further, subsequently, the pachinko balls in the second bent portions 82 of the inflow gutters 71a and 71b quickly flow into the vertical portions 83,
The pachinko ball in the inclined portion 81 quickly flows into the second bent portion 82, and the pachinko ball in the first bent portion 80 quickly flows into the inclined portion 81, and the pachinko ball in the inclined portion 79 faces the cover 77, 78. , And quickly flows into the first bent portion 80. On this occasion,
Due to the retreat of the locking claws 91a and 91b, the leading pachinko ball and the pachinko ball in the regulating portion 85 following the leading portion are almost in contact with each other.
Since the pachinko ball from the guiding portion 84 continues down at the angle of approximately 45 degrees, the pachinko ball continues to flow down in the direction 85 and gradually separates from the pachinko ball in front while changing the direction, flows down the flow adjusting portion 85, More vertical
The speed and interval of the pachinko ball from 83 are adjusted by the upper wall 89 of the guiding section 84, so that the
It will flow down in 85. In addition, the flow control section 85 and the guide section 8
4. Since the ball pressure at each part such as the vertical part 83, the bent part 82, the inclined part 81, etc. is small, the pachinko ball flows down smoothly.

Then, the discharge solenoid 9 of the discharge stopper mechanism 73a, 73b
When the locking claws 91a and 91b enter the flow adjusting portion 85 when the 2a and 92b are turned off, the pachinko balls flowing down the flow adjusting portion 85 move the locking claw 91a.
a, 91b, and the flow is prevented from flowing down.
5, guide part 84, vertical part 83, bent part 82, inclined part 81, bent part 8
0, the pachinko balls in the inclined portion 79 are also prevented from flowing down, and return to the original stationary state. Since the ball blocking portions of the locking claws 91a and 91b coincide with the swing trajectory, the impact force due to the collision of the pachinko ball is applied to the support shaft 93.
As 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 adjusting part 85, Locking claws 91a, 91b without biting pachinko balls
Enters smoothly.

That is, the inflow gutters 71a, 7 of the discharge mechanisms 42a, 42b following the guiding gutter 41.
1b, two bent portions 80 and 82, and a vertical portion 83 following the bent portion 82.
And a guiding portion 84 in which the lower side wall 88 of the vertical portion 83 protrudes and the upper wall 89 is inclined on the opposite side, and a discharge stopper mechanism is further provided in the flow regulating portion 85 inclined approximately 45 degrees below the guiding portion 84. 73a, 73
With the arrangement of b, the pachinko balls can smoothly flow down when the discharge solenoids 92a and 92b are on, and the ball pressure applied to the locking claws 91a and 91b when the discharge solenoids 92a and 92b are off reduces the pachinko ball. The flow of the sphere can be properly prevented, and the reliability is greatly improved. Also, the discharge mechanisms 42a, 42
b has a unit structure, and therefore, when each component fails, the whole unit can be easily replaced, so that it is possible to quickly respond to a failure or the like. In addition, since the solenoids are arranged vertically, it is possible to prevent dust from entering the inside and the loss of rods and the like.

The prize ball discharge gutter 43 following the discharge mechanisms 42a and 42b is composed of one system as shown in FIG.
It is formed of an inflow portion 105 connected to both drop portions 86 of 2a and 72b, and a discharge ball portion 107 provided with a downflow gutter 106 connected to a supply tray of pachinko balls on the front surface of the base 2, and both of the flow control gutters 72a and 72b are formed. Drop part
The downspout while hitting the pachinko balls that flowed in from 86 into the protruding walls
Drop on 106 and discharge to the supply pan. The distribution gutter 44 is connected to a tray at the lower front of the base 2 and discharges the pachinko balls overflowing from the downflow gutter 106 to the tray when the supply tray is full of pachinko balls. Further, the distribution gutter 44 is provided with a detection piece 108 that also serves as a gutter wall immediately below the downflow gutter 106, and a switch (overflow switch) 109 that is linked to the detection piece 108,
When the inside of the distribution gutter 44 becomes full of pachinko balls and the detecting piece 108 is pressed by the pressing force, the overflow switch 109 outputs an ON signal.

A ball drain gutter 45 branching from the middle of the prize ball discharge gutter 43 has a plate-shaped ball drain gate at the branch part as shown in FIGS. 13 (A) and (B).
110 is freely rotatable via a support shaft 111, a crank 112 fixed to the support shaft 111 outside the gutter wall is engaged with a lever 113, and a ball removal gate 110 is removed at the rear end of the lever 113. A spring 114 for urging the closed position of the gutter 45 (opening of the prize ball discharge gutter 43) is engaged, and a ball removing solenoid 116 for driving a ball removing gate 110 via a link 115 is provided on the lever 113 on the opposite side of the spring 114. Be linked.

When the ball-pulling solenoid 116 is energized, the ball-pulling gate 110 moves the ball-pulling gutter 45 against the spring 114 by the upward movement of the link 115.
When the ball-opening gate is opened and turned to a position to close the prize ball discharge gutter 43 and the energization of the ball-drawing solenoid 116 is cut off, the ball-drawing gate 110 is returned to the closed position of the ball-drawing gutter 45 by the spring 114. A switch (ball removal sensor) for turning on and off the ball removal solenoid 116 is operated by inserting a device such as a pin or a wire through an operation hole (not shown) formed on the front surface of the base 2.

The downstream side of the ball drain gutter 45 is located at the out port 11 of the game board 1.
7 (FIG. 2) is joined to an out ball lead-out gutter 118 that guides the collected out ball, and further connected to a collection gutter (not shown) at the rear of the pachinko machine.

Is "13" and the number of prize balls for winning of the specific winning ports 304, 305a, and 305b is seven.
The number of award balls on the safe II side of 2 is set to “7”.

On the other hand, the structure of the control device 200 includes a CPU 201, an interface 202, input / output terminals 203 to 208, as shown in FIGS.
It comprises a board 215 on which electric components such as a timer transmission circuit 209 and a power supply circuit 210 are arranged and connected, and a metal case 216 for housing the board 215.

IC components such as the CPU 201, transistors and relatively large capacitors, etc. are provided on the surface of the substrate 215, with the respective input / output terminals 203 to 208,
The reset switch 211 is arranged around four sides of the surface of the substrate 215, and small resistors, capacitors and the like are arranged on the rear surface of the substrate 215. Further, a metal piece 217 is attached to the ground surface of the substrate 215 at two corners of the surface of the substrate 215.

The main body 218 of the case 216 is formed by bending two longitudinal side surfaces 219 and one end surface 220 to form a casing.
A small groove 221 is provided in parallel inside 19, and a substrate 215 is applied to this groove 221 from the opening side and inserted. Openings 222 to 224 for operating the reset switch 211 are formed on the side surface 219 and the end surface 220 of the main body 218 to attach and detach wiring connectors to the input / output terminals 205 to 208 of the board 215 from outside.

The lid 225 of the case 216 is formed by bending the side surface 226 and the end surfaces 227 and 228 in accordance with the main body 218, and one of the end surfaces 228 is formed.
Is extended to cover the opening of the main body 218, and the other surfaces 226, 227
Are formed so as not to overlap the openings 222 to 224 of the main body 218. An opening 229 for attaching and detaching a wiring connector to the input / output terminals 203 and 204 of the substrate 215 from outside is formed on the end surface 228 of the lid 225. Also, on the end surface 228 of the lid 225,
2 abuts on both sections 217 attached to the ground surface of substrate 215
One contact piece 230 is bent inward.

Four fitting recesses (small holes) 231 are provided on the side surface 219 of the main body 218, and fitting protrusions 232 that fit into the fitting recesses 231 are provided on the side surface 226 of the lid 225.

The substrate 215 is inserted into the groove 221 from the opening side of the main body 218, and the lid 225 is covered while aligning the end surface 228 of the lid 225 with the opening side, and the fitting convex portion 232 of the lid 225 is fitted into the fitting concave portion 231 of the main body 218. Then, the substrate 215 is stored and supported in the case 216, and the case 216 is assembled. At the same time as this assembling, the contact piece 230 on the end face 228 of the lid 225 contacts the piece 217 on the ground surface of the board 215 with a predetermined pressing force, and the ground of the board 215 is connected to the case 216. Thus, the substrate 215 is shielded by the conductive case 216.

The control device 200 is disposed on the back surface of the base 2 as shown in FIG. 1. In this case, two sets of elastic locking members (not shown) are provided on the side of the base 2, and By pushing the case 216 in between, the protrusion 233 of the case main body 218, that is, the protrusion 233 on the outer surface side by machining the groove 221 is hooked and attached.

A wiring member 62 connected to the conductive plates 59a and 59b of the guide gutter 41 is fastened and connected to the surface of the lid 225 of the case 216 of the control device 200 via the screw 234 (fifth embodiment).
See figure). The board 215 of the control device 200 is
Of the main power supply (24V) and ground.

As described above, the control device 200 inserts the compact board 215 into the groove 221 of the case main body 218, covers the cover 225, and fits the fitting protrusion 232 into the fitting recess 231. It can be stored and supported, and the case 216 can be easily assembled. Therefore, the control device 200 can be reduced in size and weight, and the control device 200 can be easily assembled without the need for a fastening member such as a screw, and the assembling process can be greatly reduced.

Also, the board 215 of the control device 200, when the case 216 is assembled, the contact piece 230 of the end face 228 of the lid 225 contacts the piece 217 of the ground surface of the board 215 with a predetermined pressing force. The shield can be performed by the conductive case 216 that houses the substrate 215 without using a ground wire or the like. Therefore, the substrate 215 can be easily shielded by the entire conductive case 216, and this shield ensures that external noise passes through the case 216 and affects the IC components of the substrate 215. Can be prevented.

Although the control device 200 is provided on the back surface of the base 2, the mounting position is easy because of its small size, and the degree of freedom in designing the base 2 is increased. Note that the mounting and removal to and from the base 2 is performed by using the protrusion on the back side of the groove 221 of the case main body 218.
By using 233, it can be done easily.

On the other hand, in the case of a jackpot game such as the game board 1 in FIGS. 18 to 20, a large number of winning balls are discharged in a short time. A large amount of static electricity is generated due to friction between the pachinko spheres flowing with each part and the pachinko spheres are charged, but this static electricity is transmitted from the guiding gutter 41 of the prize ball discharging device 16 to the conductive plates 59a, 59b, the wiring member 62, Attenuator 61, case 216 of control device 200, substrate 215
Absorbed and released through the ground.

That is, conductive plates 59a and 59b are provided on the bottom of the passage of the guide gutter 41 following the storage tank 40 for the prize balls, and the conductive plates 59
Since a and 59b were connected to the case 216 of the control device 200 via the attenuator 61 such as a resistor, and the case 216 was connected to the ground of the substrate 215, when the pachinko ball flows down the induction gutter 41,
The static electricity is guided from the conductive plates 59a and 59b to the attenuator 61 to attenuate the energy.
6. Discharged from the main power supply side of the control device 200 to the outside via the ground of the substrate 215.

For this reason, when the pachinko ball passes through a prize ball sensor (discharge sensor, safe sensor, etc.) or a sensor on the game board 1 (start switch, cycle switch, count switch, etc.), the electric discharge from the pachinko ball causes Destruction of the sensor and malfunction of the sensor can be reliably prevented. In addition, since the static electricity released to the conductive plates 59a and 59b is attenuated by the attenuator 61, the static electricity noise does not adversely affect the substrate 215 of the control device 200.

If the conductive plates 59a and 59b are connected to the frame side of the base 2 and the static electricity is absorbed by the frame and naturally discharged, the ground must be connected when the amount of static electricity is large. Since the electric power is discharged from the main power supply side of the control device 200 in this manner, static electricity can be reliably released, and high reliability can be obtained.

In addition, since the main power supply of the control device 200 discharges static electricity from the control device side of the game board 1, the performance of absorbing noise differs depending on the structure of the control device. There is no problem that the conductive plates 59a and 59b must be connected each time the board 1 is replaced.

Next, the contents of control by the control device 200 will be described based on the flowcharts of FIGS. 21 to 43 (A) to (C).

FIG. 21 shows the main flow, which is “initialization processing” at power-on, “background job” for monitoring each sensor, etc., “ball removal processing”, prize ball discharge processing ”, and“ discharge illegal ”. Processing "and the like.

In the initialization process, the stack pointer is set as shown in FIG. 22, the input / output ports of the CPU 201 are initialized, the output to each device is turned off, the RAM is cleared, and the number of illegal monitoring balls is cleared. Are set in the counters for illegality monitoring on the discharge 1 and 2 sides in FIG.

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

The number of award balls on the Safe I and Safe II sides is determined by the award ball number setting circuit.
By selecting a combination of the resistance values of the 212 resistances 213a, 213b, 214a to 214b, it is possible to select freely and easily, and therefore it is possible to set the number of prize balls suitable for the model of the game board 1. . Also, since the number of award balls of the award ball number setting circuit 212 is periodically rewritten in the RAM, noise and noise such as heat and static electricity inside the pachinko machine are absorbed and shielded as described above, so there is little influence. However, even if these may destroy the prize ball data stored in RAM,
The number of award balls can be immediately reset in the RAM. Therefore, when discharging the prize balls based on the stored value of the number of prize balls in the RAM, the number of prize balls is not missed, and high reliability is secured.

FIG. 24 shows a background job, which is executed at regular intervals, such as “timer monitoring”, “safe sensor monitoring”, “discharge sensor 1 monitoring”, “discharge sensor 2 monitoring”,
It consists of "ball sensor monitoring" and "safe II signal processing". The execution cycle is updated and monitored in FIG. 25, and the timer is updated and monitored in FIGS. 26 and 27.

The safe sensor is monitored by accurately detecting the presence or absence of a pachinko ball (prize ball) by the safe sensor between the two ball blocking portions of the stopper mechanism 20 provided in the flow control portion 29 of the flow control gutter 18 of the prize ball processing device 15. In the detection, as shown in FIG. 28, the signal of the safe sensor is read, and the pachinko ball is detected based on the state of the signal in a certain time. When the signal of the safe sensor changes from off to on, it is determined that there is a ball when 10 msec has elapsed while the signal is on. When the safe sensor signal turns off,
It is determined that there is no ball when 4 msec has elapsed after the off-state.

In the process of the safe sensor, if the change of the signal of the safe sensor is temporary, it is regarded as noise and invalidated. The winning ball that has entered the flow control section 29 of the flow control gutter 18 is temporarily prevented from flowing down by the stopper mechanism 20, so that the detection time of the presence of the ball by the safe sensor is sufficient for 10 ms. As a result, the presence or absence of a winning ball can be accurately detected.

The discharge sensors 1 and 2 are monitored by the discharge mechanism 42a (discharge 1 side) and 42b.
The pachinko balls (prize balls) flowing down the flow control portions 85 of the flow control gutters 72a and 72b on the (discharge 2 side) are accurately detected by the discharge sensors 1 and 2 upstream of the discharge stopper mechanisms 73a and 73b. Things
As shown in FIG. 29, FIG. 30, and FIG.
The detection (rising detection) is performed based on the previous signal and the current signal in (2). That is, when the signals of the discharge sensors 1 and 2 change from off to on (previous), if the signal of the present discharge sensors 1 and 2 is on, there is a ball, that is, the pachinko ball is
Judge that it has entered 2 When the signals of the ejection sensors 1 and 2 are turned off (previous), if the signal of the current ejection sensors 1 and 2 is off, it is determined that there is no ball, that is, the pachinko ball is not in the ejection sensors 1 and 2. .

44 (A) and (B) show an example of the processing of the discharge sensors 1 and 2. In the case of frame 2 or 10, since the sensor signal changes from off to on and then off again, The signal ON is regarded as noise and invalidated. Frame 5
Alternatively, in the case of 13, since the signal of the sensor changes from off to on and then the signal is also turned on this time, it is determined that there is a ball (rising) at the time of this signal input. In the case of frames 6 and 7, it is determined that there is a ball. In the case of the frame 9, since the signal of the sensor changes from on to off and then the signal is also turned off this time, it is determined that there is no ball (falling) at the time of inputting the signal this time. By the processing of the discharge sensors 1 and 2,
The prize balls flowing down the flow control section 85 of the flow control gutters 72a and 72b can be accurately detected, and the prize balls flowing down can be counted.

Also, by monitoring the discharge sensors 1 and 2, the counters on the discharge 1 and 2 sides are decremented by 1 when the rise is determined. In a state where the pachinko balls are prevented from flowing down by the discharge stopper mechanisms 73a and 73b, the discharge sensors 1 and 2 detect the second pachinko ball following the head.

The ball removal sensor monitoring is for detecting whether or not the ball removal sensor is turned on by the operation of the instrument inserted from the operation hole on the front surface of the base 2, and as shown in FIG. When the signal from the current ball-pull sensor is turned on when the signal changes from off to on (previous), it is determined that the ball-pull sensor is on. When the signal from the ball-drop sensor is off, if the signal from the ball-drop sensor this time is off, it is determined that the ball-drop sensor is off.

In this way, it is possible to accurately detect the winning balls, the prize balls on the first and second discharge sides, and the ON state of the ball-absorbing sensor. That is, the prize ball is taken from the state of the signal of the safe sensor for a certain time,
1, 2, the ball removal sensor detects the prize ball and the sensor ON by comparing the previous signal with the current signal, so that the sensor signal and the noise can be distinguished, and the malfunction of the control device 200 due to the erroneous signal can be reliably performed. Can be prevented. In addition, by this, for example, a metal part such as a metal frame of a pachinko machine is discharged by an electronic writer or the like to generate noise, thereby generating a prize ball discharge device.
Unauthorized acts such as malfunctioning of 16 etc. can also be reliably prevented.

Safe II signal processing is performed in the special winning port 304, 305 of the game board 1.
a, 305b, when there is a winning ball, the number of winning balls is stored based on a safe II signal from the control device of the game board 1,
Select the number of prize balls on the Safe II side.

Here, the operation of the control device of the game board 1 as a game control circuit will be described. If there is a prize in the specific winning opening 304, 305a, 305b as shown in FIGS. 45 (A) and (B), the winning number is reduced. At the same time, the safe II signal is output for 300 ms in synchronization with the call signal from the control device 200 in accordance with the storage. After this output, the winning storage number is decremented by one.

On the other hand, as shown in FIGS. 33 (A), (B), and FIG. 34, the control device 200 outputs a call signal every 50 msec in order to adjust the timing of the processing, and the safe control from the control device of the game board 1. When receiving the II signal, when the signal continues for 10 msec, it is determined that there is a safe II ball. When it is determined that there is a safe II ball, a call signal is output for 320 msec, and a safe II counter for storing the number of safe II balls is incremented by one. After this, the call signal is turned off for 170 msec, and again
Outputs a call signal every 50 ms. The next Safe II
The signal is not accepted until after the call signal is output for 320 msec and then off for 170 msec.

FIG. 46 shows a timing chart of the safe II signal processing. By using the call signal in this manner, the transmission and reception of the signal can be performed accurately, and the control becomes accurate and easy.
During the suspension of the control device of the game board 1, the ready signal from the control device changes to "H" and the safe II signal processing is not performed.

Then, when the presence of a winning ball is detected by the safe sensor monitoring, a prize ball discharging process is started. After confirming the prize ball discharge conditions, as shown in Fig. 35, the prize ball discharge processing counts the number of prize balls on the safe I side if there is no safe II ball and the prize on the safe II side if there is a safe II ball. The number of balls is set, the set number of prize balls is discharged, and after the discharge, the winning balls are discharged.

The prize ball discharge condition is satisfied when 400 msec (discharge weight timer) elapses from the end of the previous discharge process, there is a winning ball, and the discharge sensors 1 and 2 continue the ball present state for 50 msec as shown in Fig. 36. I do. That is, there is no winning ball during the previous discharging process, no discharging of the winning ball, there is a winning ball, there is a prize ball in the flow control gutter 72a, 72b of the discharging mechanism 42a, 42b, and if there is no error, discharging is OK. It is.

For the prize ball number set, a discharge method suitable for the prize ball number is selected in FIGS. 37 and 38 (A) and (B), and prize ball discharge is started. That is, when the number of prize balls on the safe I side (10 to 15) and the number of prize balls on the safe II side are 9 or more, the number of prize balls is divided (substantially by half) and divided. The number of prize balls is set on the discharge 1 and 2 counters, and both discharge mechanisms
The combined discharge from 42a and 42b is performed. When the number of prize balls is eight or less in the case of the safe II, the number of prize balls is alternately set in the counters on the first and second discharge sides, and the discharge mechanisms 42a and 42b perform alternate discharge. When the number of prize balls is one, one is also discharged. At this time, the corresponding discharge Sols 1, 2 are turned on. In the case of combined discharge and alternate discharge, the set value of the counter is set to a value which is -1 in advance.

When the prize ball discharge is started, each time the rising of the falling prize ball is detected by monitoring the discharge sensors 1 and 2, the counters of the discharge 1 side and 2 side are decremented by one, and FIGS. 39 and 40 are used. When the counters on the discharge 1 and 2 sides become "0" as shown in FIG.
The discharge of the prize balls on the b side is completed, and the corresponding discharge Sols 1 and 2 are turned off. In this case, if the counters on the discharge 1 and 2 sides do not become "0" even after 3 seconds from the start of discharging the prize ball, the discharge
After turning off Sol1 and Sol2, discharge error processing starts (described later).

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

One discharge (the number of prize balls “1”) is to selectively discharge one prize ball from one of the discharge mechanisms 42a and 42b. As shown in the timing chart of FIG. 47, the discharge start is OK. The discharge Sol1 of one of the discharge mechanisms 42a and 42b is turned on, and the discharge Sol1 is turned off after 35 ms. Next, in the case of discharging one piece, when the discharge start is OK again, the other discharge Sol2 of the discharge mechanisms 42a and 42b is turned on, and after 35 msec, the discharge Sol2 is turned off. Note that emissions S
The discharge sensors 1 and 2 are turned off once and then turned on in response to the turning on and off of ol1 and ol2.

When the discharge Sol 1 or 2 is turned on, the discharge stopper mechanism 73
The pachinko ball 91a or 91b of a or 73b is retracted from the corresponding flow adjusting portion 85, and the pachinko ball that has been prevented from flowing down by the locking claw 91a or 91b is released. The first ball in the ball falls into the prize ball discharge gutter 43, and the second and subsequent balls start flowing down. However, if the discharge Sol 1 or 2 is turned off 35 ms later, the second ball starts flowing down. Immediately after the locking claw 91a or 91b
And the second and subsequent balls are prevented from flowing down by the locking claws 91a or 91b (see FIGS. 12 (A) and 12 (B)). As a result, one prize ball is discharged.

In the case of one discharge, after the discharge Sols 1 and 2 (selected side) are turned on, the discharge Sols 1 and 2 are detected by detecting the rising of the discharge sensors 1 and 2.
Is turned off, two balls are ejected in relation to the detection position of the ejection sensors 1 and 2 (the second ball following the head is detected in a state where flow is stopped). Is impossible, and discharge Sol is detected by detecting the falling of discharge sensors 1 and 2.
If 1,2 is turned off, the discharge of Sol1,2 will be delayed unless the inclination of the flow regulating part 85 is slowed down and the falling speed of the ball is slowed down. Discharged to
By turning on Sol1 and Sol2 for a specified time, that is, by controlling the time, one prize ball can be properly discharged. It should be noted that if the inclination of the flow control section 85 is made gentle and the falling velocity of the ball is reduced, the discharge time and the processing time in the alternate discharge or the combined discharge with a large number of prize balls become longer, which is not suitable.

Alternate discharge (prize ball count “2” to “8”) is based on the prize ball count “2” to
The prize ball corresponding to “8” is selectively discharged from one of the discharge mechanisms 42a and 42b. As shown in the timing chart of FIG. 48 (when the number of prize balls is three), the discharge start is OK.
Then, one discharge Sol1 of the discharge mechanisms 42a and 42b is turned on, the locking claw 91a is retracted by this ON, and the pachinko ball starts flowing down from the corresponding flow regulating portion 85, and the discharge sensor 1 flows down accordingly. When the rising of the pachinko ball is detected and the rising is detected a predetermined number of times (the number of award balls-1), the discharging Sol1 is turned off.
When alternate discharge is performed next time, the discharge is OK again, the other discharge Sol2 of the discharge mechanisms 42a and 42b is turned on, and similarly, the pachinko ball starts flowing down from the corresponding flow regulating unit 85, and the discharge sensor 2 is turned off. When the rising of the falling pachinko ball is detected and the rising is detected a predetermined number of times (the number of award balls-1), the discharging Sol2 is turned off.

That is, when the discharge Sol 1 or Sol 2 is turned on, the locking claws 91a or 91b recede, and the leading pachinko ball flows from the corresponding rectifying portion 85, and subsequently, the subsequent sphere flows from the rectifying portion 85 upstream and the guiding portion 84 side. , These balls fall sequentially from the top ball to the prize ball discharge gutter 43, and the discharge sensor 1
Alternatively, the pachinko spheres flowing down are counted from the detection of the rise of the pachinko spheres by 2. At this time, the first ball and the second ball of the flow regulating section 85 are not counted depending on the positions of the discharge sensors 1 and 2, but are counted from the third ball. Then, the pachinko balls are counted by the set value of the counter on the corresponding discharge 1 or 2 side, and when the discharge Sol 1 or 2 is turned off,
The ball counted last time falls to the prize ball discharge gutter 43 before the corresponding engaging claw 91a or 91b enters the flow adjusting portion 85, and the ball at the present count and its subsequent ball enter the flow adjusting portion 85. The flow is prevented by the corresponding engaging claws 91a or 91b (see FIGS. 12 (A) and 12 (B)). As a result, the number of prize balls obtained by adding +1 to the counted number is discharged together with the first ball and the second ball. In the case of Fig. 48, the count number is 2
, Three prize balls are ejected.

In this way, in the alternate discharge, the number of pachinko balls counted from the number of prize balls minus one is counted and the discharge Sol is turned off, so that the prize balls corresponding to the number of prize balls can be discharged properly.
In addition, while the discharge Sols 1 and 2 (selected side) are on, the first ball and the second ball of the flow control part 85 flow down the flow control part 85 while almost touching each other, and the third and subsequent balls from the guiding part 84 Since the flow control part 85 continues at an angle of about 45 degrees, it gradually flows away from the front sphere while changing direction and flows down the flow control part 85, and the subsequent sphere from the vertical part 83 is the upper wall of the guiding part 84 Because the speed and interval are adjusted by 89,
Each flows down the flow regulating section 85 at a predetermined separation distance. For this reason, when the discharge Sols 11 and 2 are turned off, the greater the number of prize balls, the easier it is for the locking claws 91a and 91b to enter the flow adjusting portion 85, but even when the number of prize balls is two, The stopping claws 91a, 91b can easily enter.

For one-piece discharge and alternate discharge, one of the two systems of discharge mechanisms 42a and 42b is used to select whether to discharge a prize ball every time the processing is started. That is, when one piece is continuously discharged according to the winning ball, for example, for the first winning, the discharging mechanism 42a discharges, and for the next winning, the discharging mechanism 42b side. Discharge takes place (see Figure 47).
Similarly, in the case where the alternate discharge is continuously performed, for example, the discharge is performed on the discharge mechanism 42a side for the first winning, and the discharge is performed on the discharge mechanism 42b side for the next winning (for example, Four
See Figure 8). Further, in the case where one discharge and alternate discharge are continuous, for example, if one discharge is first performed on the discharge mechanism 42a side, the next alternate discharge is performed on the discharge mechanism 42b side. As described above, since the prize balls are discharged by alternately using the two discharge mechanisms 42a and 42b, it is possible to prevent the flow of the balls from being biased in the guiding gutter 41 or the like, thereby causing the clogging of the balls, and the like. Can keep the ball discharged smoothly. It should be noted that, even when only one of the discharges or the alternate discharge is used depending on the setting of the number of award balls, the discharge mechanisms 42a and 42b are used alternately.

Combined emissions (prize balls “9” or more) are from “9” to “1”
A prize ball corresponding to 5 "is discharged from both discharge mechanisms 42a and 42b. As shown in the timing chart of FIG. 49 (when the number of prize balls is 10 and 15), the discharge start is OK. The discharge Sols 1 and 2 of both discharge mechanisms 42a and 42b are turned on, and the pawls 91a and 91b are retracted by these ONs, and the pachinko balls start flowing down from both flow regulating portions 85. 2 detects the rising of the pachinko ball flowing down, and discharge sensor 1
2 is the predetermined number of rises (number of divided prize balls -1)
In this case, when the number of prize balls is 10, in this case, the discharge sensor 1 is set to 4 times by the set value of the discharge 1 side counter = 4, and the discharge sensor 2 is set to 4 by the set value of the discharge 2 side counter = 4.
When the rising is detected, the corresponding discharge Sols 1 and 2 are turned off. When the number of prize balls is 15, when the discharge sensor 1 detects the rising of the discharge sensor 1 seven times by the set value of the discharge 1 side counter = 7 and the discharge sensor 2 by the set value of the discharge 2 side counter = 6 six times, Turn off corresponding Sol1 and Sol2 respectively.

That is, by turning on both the discharge Sols 1 and 2, the locking claws 91a and 91b recede, respectively, leading pachinko balls from the flow regulating part 85, and subsequently, these subsequent balls start flowing down, and these balls are moved to the leading position. The balls fall sequentially from the ball to the prize ball discharge gutter 43, and the pachinko balls flowing down the flow control section 85 are detected by the discharge sensors 1 and 2 in response to the rise of the pachinko ball.
Count for the set value of the
By turning off Sol1 and Sol2, the prize balls of the number obtained by adding +1 to the set value of the discharge 1 side counter are discharged from the flow regulating section 85 on the discharging mechanism 42a side, and the discharge 2 side from the flow regulating section 85 on the discharging mechanism 42b side. The number of prize balls obtained by adding +1 to the set value of the counter is discharged. At this time, the first sphere and the second sphere of the flow regulating unit 81 are not counted depending on the positions of the discharge sensors 1 and 2, respectively, but are counted from the third sphere. The flow down is prevented by turning off the discharge Sol1,2. As a result, as shown in FIG. 49, when the number of prize balls is 10, five prize balls are discharged from the flow adjusting portions 85 of the both discharge mechanisms 42a and 42b, respectively, and when the number of prize balls is 15, the prize balls are discharged. Mechanism 42a
8 prize balls from the flow control section 85 of the discharge mechanism 42b
Five to seven prize balls are ejected.

As described above, in the combined discharge, the number of prize balls is divided, and the number of pachinko balls is counted down by one each from the divided prize balls, and the discharge Sols 1 and 2 are turned off. Can be discharged properly. In the combined discharge, the prize balls are discharged using both discharge mechanisms 42a and 42b when the number of prize balls is large, so that the discharge time can be reduced. In addition,
In the case of combined discharge, the sphere from the vertical part 83 or later upstream of the guiding part 84 flows down the flow regulating part 85 and is discharged when the distance between the spheres is large.
To turn off 1,2, of course, the flow control section 85 of the locking claws 91a, 91b
Getting inside is easy.

By the way, when ball clogging occurs during these discharge processes, a specified number of prize balls may not be discharged. For this reason, it takes 3 seconds (discharge monitoring timer) before the value of the corresponding discharge 1 or 2 counter becomes “0” from the start of discharge in FIG. 39.
When the time has elapsed, a discharge error due to ball clogging is determined, and the discharge Sols 1 and 2 are turned off.

That is, the discharge error due to the ball clogging can be accurately detected from the counter values of the corresponding discharge 1 side and 2 side after the lapse of the predetermined time, and in this case, the ball clogging is performed while the discharge Sols 1 and 2 are kept in the off state. Will be fixed.

On the other hand, when the ball is clogged, if the value of the counter on the corresponding discharge side 1 or 2 is "1", the final pachinko ball is not counted, but the ball is discharged up to the previous pachinko ball. In this case, a specified number of prize balls are discharged.

After correcting the clogged ball, the discharge sensors 1 and 2
Is returned from the ejection error when the state with the ball is continued for 3 seconds. After this return, the number of award balls before the error is reset in the corresponding discharge 1 side and 2 side counters, and the discharge processing is started again.
When the values of the corresponding discharge 1 and 2 counters are “1”, a specified number of prize balls are discharged, and the discharge processing ends.

FIG. 50 shows a discharge error and a timing chart after the return (when the number of prize balls due to simultaneous discharge is 10), the discharge monitoring timer (3 seconds) starts simultaneously with turning on the discharge Sols 1 and 2, and for example, the discharge is performed. When the specified number of pachinko balls are counted on the sensor 2 side, the discharge Sol2 is turned off.
If the discharge monitoring timer times out before the specified number of pachinko balls are counted on the side, it is determined that a discharge error has occurred, and the discharge Sol1 is turned off at the same time as the time is up, and the system waits for recovery. Then, when the recovery is completed, the discharge start condition is determined when the corresponding sensor 1 is kept on for a period of the discharge monitoring timer (3 seconds), and if OK, the specified number of prize balls have not been discharged last time. The discharging process is performed again with the same number of award balls. In particular, even if such an error occurs, by performing the discharging process again with the same number of prize balls after recovery, a predetermined prize ball is always discharged for winning, so that the player using the prize ball Trouble can be prevented.

When the prize ball is discharged while the locking claws 91a and 91b remain retracted from the flow regulating portion 85 due to a failure of the discharge Sol 1 or 2 when the prize ball is not being discharged, the illegal monitoring is performed. Error processing is performed by the application counter (described later).

When the discharging process is completed, the safe Sol of the stopper mechanism 20 is turned on in FIG. At the same time, discharge weight timer (400 ms), safe ball discharge monitoring timer (200 ms)
Is set. When this Safe Sol is turned on,
When the winning ball in the flow adjusting section 29 is discharged and the safe sensor determines that there is no ball, the safe Sol is turned off after 100 msec in FIG. 42 and the discharging of the winning ball is completed. If the prize ball is discharged by the prize ball on the Safe II side, the Safe II counter will be
Do one.

FIG. 51 shows a timing chart of the safe ball discharging process. As shown in FIG. 51, the safe Sol of the stopper mechanism 20 is turned on at the same time as the end of the winning ball discharging process. When the winning ball is released from the and is discharged to the outlet gutter 19, the discharging of the winning ball is confirmed by the safe sensor being turned off for 4 ms, and the safe Sol is turned off 100 ms after that.

Since safe ball discharge is performed at the end of prize ball discharge processing,
If the predetermined prize ball is not discharged due to the above-described error or the like during the prize ball discharge processing, the winning ball is kept in a state where flow is prevented from flowing down by the corresponding locking claw 33, and is discharged to the outlet gutter 19 side. There is no. The locking claw 33 is retracted by turning on the safe Sol, while the locking claw 34 on the upstream side
When the safe Sol is turned off, the locking claw 34 retreats, while the locking claw 33 enters the flow regulating section 29 (see FIGS. 3A and 3B). For this reason, when there is a subsequent winning ball in the flow adjusting section 29, the succeeding winning ball is replaced with the previous winning ball by turning off the safe Sol, and is prevented from flowing down by the locking claw 33.

In this way, the safe ball is discharged. If the safe ball discharge monitoring timer (200 msec) times out after the safe Sol is turned on and the safe sensor has a winning ball, a discharge error is determined.

In this case, a discharge error occurs when the locking claw 33 does not retreat from the flow regulating section 29 due to a failure such as Safe Sol, or when the safe sensor is turned on and breaks down. Can be detected from the state of the safe sensor when a predetermined time has elapsed.

Then, if there is a discharge error, the ball removal gutter 45 ball removal So
l is turned on and the safe sensor detects no ball
It becomes a stop state. That is, the prize ball of the prize ball system is collected from the ball drain gutter 45 by turning on the ball drain Sol, and in this state, a failure point such as the Safe Sol or the safe sensor is restored. After recovery, if the safe sensor detects no ball,
In the figure, Safe Sol and ballless Sol are returned to the off state.

Fig. 52 shows the timing chart of safe ball discharge error processing. The safe ball discharge monitoring timer (200 ms) is started at the same time that Safe Sol is turned on, and the safe sensor does not detect the absence of a ball until the time is up. If it is in the state, it is determined that a discharge error has occurred, the ball-solving Sol is turned on, and the recovery waits. Then, when the recovered safe sensor detects that there is no ball, the safe Sol and the ball emptying Sol are turned off, and the error processing ends.

In other words, the safe ball discharge error can be accurately detected, and when the discharge error occurs, the standby state is set.
It is possible to prevent the discharge process from being started while the safe sensor and the safe sensor are in a failure state, and to reliably prevent the prize ball from being discharged due to a malfunction.

Each time the prize ball is discharged, a counter for monitoring fraud is set, and fraud monitoring is performed. In other words, when a prize ball is ejected from the ejection mechanisms 42a and 42b at times other than during the ejection of the prize ball, an illegal error is generated when the illegality monitoring counters on the ejection side 1 and 2 count five prize balls. Judge and
In FIG. 21, Sol without ball is turned on, and the ball is stopped.

If the prize ball is ejected due to some abnormality while the prize ball is not being ejected and there is no winning ball, or the prize ball is ejected as it is following the ejection of the prize ball, When a prize ball is ejected due to some abnormality during the ball ejection process or the like, an illegal error is determined based on the count value of the illegality monitoring counter.

The locking claw of the discharge stopper mechanism 73a or 73b
The prize ball may be obtained when the 91a or 91b is retracted from the flow regulating unit 85 due to the failure of the discharge Sol 1 or 2 or the locking claws 91a or 91b are forcibly moved to the retracted position due to misconduct. May be ejected, but since the ejection of the prize ball is constantly monitored, if there is any irregularity in the ejection, the irregularity can be immediately detected. Also, when detecting fraud, the ball release Sol is turned on, so the prize ball is
5 to prevent the prize balls from being discharged to the supply tray side.

In this state, recovery from a failure or improper operation is performed, and a reset switch (see FIGS.
Turning on (see figure) turns off Sol without ball, and the fraud monitoring process ends and restarts.

FIG. 53 shows a timing chart of the fraud monitoring process. When the ball is not being discharged, for example, when the movement of the ball is detected by the discharge sensor 1, the fraud monitoring counter on the discharge 1 side is checked every time the rising of the ball is detected. +1 and the counter becomes "5"
At the same time, turn on Sol without ball and wait for recovery.
And when the recovery is completed and the reset switch is turned on,
The counter is cleared, the ball-solving Sol is turned off, and the process ends.

In this way, it is possible to accurately detect the improper discharge due to a failure of the discharge Sol1, 2 or the like or an improper act, and at the time of improper operation, the prize ball is collected from the ball drain gutter 45 by the ball-pulling Sol, and the discharge is immediately stopped, Since the apparatus is in the standby state, it can sufficiently cope with failures such as discharge Sols 1 and 2 and prevention of fraud.
FIGS. 43 (A) to 43 (C) show the ball-pulling process, which is performed when the gaming machine is stopped, when the game store is closed, when each device is out of order, or when inspection is performed. The ball removal processing cannot be performed when there is a winning ball, during the discharge of a prize ball, or during error processing.

When an instrument such as a pin is inserted from the operation hole on the front surface of the base 2 to turn on the ball removal sensor (by monitoring the ball removal sensor),
When the ball release Sol is turned on and the ball release start timer (1 second) elapses, the discharge stoppers 73a and 73b discharge Sol1 and Sol2.
2 is turned on.

When the ball release Sol is turned on, the ball release gate 110 provided at the branch portion of the ball release gutter 45 is opened, and the ball release start timer (1 second) so that the ball is not discharged while the ball release gate 110 is being opened. After the lapse of the time, the discharge Sols 1 and 2 are turned on, and the locking claws 91a and 91b are retracted from the flow adjusting portion 85. As a result, the prize balls in the upper tank 40 of the prize ball discharge device 16 and the prize balls in the guiding gutter 41 and the discharge mechanisms 42a and 42b flow down from the prize ball discharge gutter 43 to the ball pulling gutter 45, and the rear of the pachinko machine. Discharged to a collection gutter not shown,
Collected.

Then, the prize balls in the upper tank 40, the guide gutter 41, and the discharge mechanisms 42a and 42b are discharged to the collection gutter, and when the discharge sensors 1 and 2 are turned off, a discharge 1-2 ball no-timer (3 seconds) is set. After this timer has elapsed, the discharge Sols 1 and 2 are turned off, and then the ballless Sol
Turn off. At this time, even if the discharge sensors 1 and 2 are turned off, if the remaining balls that have not flowed out from the upper tank 40 etc. flow down with a delay and the discharge sensors 1 and 2 are turned on, The two-ball no-timer is reset, and after this timer has elapsed, the discharging Sols 1 and 2 and the ballless Sol are turned off.

As a result, all the prize balls are discharged and collected, and after the discharge sensors 1 and 2 continue to be in the OFF state for 3 seconds, the locking claws 91a and 91b return to the inside of the flow regulating section 85, and the ball releasing gate 110 removes the ball. It returns to the closed position of the gutter 45 (the prize ball discharge gutter 43 is open), and ends automatically. If there is no collected ball, the process is automatically terminated when the ball removal start timer elapses.

FIG. 54 shows a timing chart of the ball removing process,
The ball removal Sol is turned on by the detection of the ball removal sensor being turned on, and one second later, the discharge Sols 1 and 2 are turned on to start the ball removal. When the ball removal is completed, when the discharge sensors 1 and 2 are turned off for 3 seconds, the discharge Sols 1 and 2 and the ball removal Sol are turned off, and the process ends.

In this way, turning on the ball removal sensor allows the ball to be removed, and all the prize balls are discharged and collected.
When 2 is turned off for 3 seconds, the ejection claws 91a and 91b and the ball-pulling gate 110 return to their original positions by turning off the discharge Sols 1 and 2 and the ball-pulling Sol, and the operation is automatically terminated. Work is easy without any operation.

If it is desired to forcibly stop the ball removal during the ball removal process, the ball removal sensor is turned on again by inserting a device such as a pin again through the operation hole of the base 2 and turning on the ball removal sensor. Will end.

That is, when the ball release sensor is turned on after the ball release sensor is turned on, the forced end timer (1 second) is set in FIG. 43 (B), and if the prize balls are being collected, the discharge sensors 1 and 2 are set to the ball release sensors. At the same time as detecting the rising edge, the corresponding Sols 1 and 2 are turned off. If the prize balls have been collected, the Sols 1 and 2 are turned off when the forced termination timer has elapsed. Then, 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 inside of the flow regulating portion 85, and the ball removal gate 110 returns to the closed position of the ball removal gutter 45, thereby forcibly terminating.

FIG. 55 shows a timing chart of the forcible termination of the ball-pulling process (when the discharge 1 side is collecting prize balls and the discharge 2 side is after collecting). On the discharge 2 side, the discharge Sol2 is turned off after one second, and on the discharge 1 side, the discharge Sol1 is turned off when the discharge sensor 1 detects the rising of the ball.
Is turned off.

In this forced termination, when the prize ball is being collected, the ball whose rising is detected and the subsequent ball are returned to the flow control section 85 by the locking claws 91a, 91a.
By b, the flow is prevented without difficulty.

(Effects of the Invention) As described above, according to the present invention, a specific prize detecting means for detecting a prize ball which has prize a specific prize area provided on a game board, and a prize flow including a prize area including the specific prize area flows down. A prize ball detecting means for detecting all the prize balls and outputting a detection signal, and a ball game machine in which a required number of balls are discharged by operating a ball discharge device based on the detection signal. A game control circuit electrically controlling a game-related control including a detection process of the specific winning detection means, and a discharge control circuit electrically controlling a discharge operation of the ball discharging device. The circuit stores the detection signal from the specific prize detection unit and outputs a signal related to a predetermined number of prize balls to the discharge control circuit based on both the detection signals from the specific prize detection unit and the prize ball detection unit. Against The discharge control circuit outputs the signal for a predetermined time so as to be recognizable, and subtracts one from the stored detection signal of the specific winning detection means. The discharge control circuit outputs the signal related to the number of prize balls. Since the input of the signal related to the number of prize balls for a predetermined time after the input is prohibited, the signal related to the number of prize balls can be input at the most effective timing.

In addition, since the signals relating to the number of prize balls are not input one after another but are input at predetermined intervals, the operation of the ball discharging device can be reliably controlled, and no malfunction occurs.

Furthermore, since the ball discharge device does not malfunction, the player is not anxious that the prize ball may be wrong, and the fairness of the prize ball discharged to the player is guaranteed. Can be.
