Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a pachinko machine, and more particularly, a variable prize ball machine that discharges balls stored in a tank and guided out by a guiding gutter in a plurality of different numbers of prize balls. Relating to a release device.

(Prior art and its problems) A variable prize ball discharging device is a device that can discharge multiple types of prize balls, for example, two types of prize balls: a predetermined number of prize balls and a number of prize balls greater than the predetermined number. be.

However, the conventional variable prize ball discharging device that can discharge multiple types of prize balls has a complicated and large structure, making it unsuitable and impractical for implementation in recent pachinko machines. . In addition, since the prize ball release cycle is relatively long, it is difficult to use pachinko machines like recent pachinko machines, which are equipped with an auxiliary game device and generate a large amount of winning balls in a short period of time when a "jackpot" occurs in the auxiliary game. (For example, Japanese Patent Laid-Open No. 53-95741).

Furthermore, in the case of the conventional variable prize ball ejection device,
The type of prize balls to be released is predetermined according to the winning mode, and the predetermined number of prize balls is determined by a member actuated by an electric drive source, and whether this member operates or not. Depending on the game, some type of prize ball with a different number of balls was released.

In pachinko parlors that have installed pachinko machines equipped with such variable prize ball ejecting devices, in order to arouse the gambling spirit of players and attract customers, they use means to prevent the variable prize ball ejecting devices (such as When the minimum number of prize balls is released, the connector of the electrical drive source of the means (which operates to allow only the number of prize balls to be released and prevent the remaining prize balls from falling) is intentionally disconnected, and the minimum number of prize balls is always released. Since it is easy to modify this variable prize ball discharging device (simply by removing the above-mentioned connector) in order to release a larger number of balls, there is a risk that the provision of healthy recreational games will be impaired. It was hot. The present invention aims to solve this problem.

(Means for Solving Problems) The present invention includes a tank 2 for storing balls, a derivation gutter 4 for deriving the balls stored in the tank 2, and a plurality of types of prize balls for the balls derived by the deriving gutter 4. In a pachinko machine having a variable prize ball ejecting device capable of ejecting a variable prize ball, the variable prize ball ejecting device has a storage section 3 for storing a predetermined number of balls drawn out by the guiding gutter 4, and a drive means. (for example, 12), the prize ball discharging means 10 is arranged near the prize ball discharging means 10, and when the electric drive source 35 is in a non-energized state, the prize ball discharging means 10 and a second position in which it cannot act on the storage section 3 of the prize ball discharging means 10 when the electric drive source 35 is energized. Prevention means 3

and at the same time, the electrical drive source 35 of the blocking means 33 is de-energized.
to the first position and release a predetermined number of prize balls, and in the second winning mode, the prize ball releasing means 1
At the same time, the electric drive source 35 of the blocking means 33 is energized and the release blocking member 30 is driven.
and control means (for example, flip-flops 41, 47, AND gate 46, etc.) for converting the ball to the second position and ejecting more prize balls than the predetermined number.

(Example) Hereinafter, the present invention will be described based on the drawings showing an example.

First, the outline of the variable prize ball discharging device will be explained based on FIG. 1.

The prize balls are passed from a tank 2 provided at the top of the back mechanism panel 1 that stores the prize balls, through a lead-out gutter 4 that guides the prize balls to the ball case 3 while properly rectifying the prize balls in the tank 2. , up to the ball sheath case 3, which serves as a storage section for storing a predetermined number of prize balls.

The ball sheath case 3 serving as a storage section is normally stationary at a position where its upper end side communicates with the downstream end of the outlet gutter 4, and its lower end side faces a stopper 6 adjacent to the socket 5A of the prize ball discharge gutter 5. In this stationary position, the prize balls in the ball sheath case 3 are stored without falling down by the stopper 6, but when the ball sheath case 3 tilts and its lower end faces the socket 5A of the prize ball discharge gutter 5. , the prize ball in the ball case 3 is released. At this time, the stopper piece 3A attached to the upper end side of the ball sheath case 3 moves to a position where it closes the downstream end opening in the outlet gutter 4, thereby preventing the prize balls from flowing down in the outlet gutter 4.

The prize balls falling into the prize ball discharging gutter 5 collide with the prize ball discharging bell 7 on the way, making a discharge sound, and then passing through the discharge port 5B to a batted ball supply tray (not shown) protruding from the front of the pachinko machine. z) flows out. On the other hand, the ball sheath case 3 serving as a storage portion is returned by a return spring 8 and stopped at the original position by a stopper 8'.

Reference numeral 10 in the figure is a prize ball release means that acts on the storage section to release the prize ball. The prize ball discharging means 10 of the embodiment is a tilting device that tilts the ball sheath case 3 as a storage section. This tilting device 10 includes a link mechanism 11 connected to the ball sheath case 3, and an electromagnetic solenoid 12 as a driving means for operating the link mechanism 11.

In FIG. 2, the link mechanism 11 includes a first link 11A whose rear end side is pivotally connected to a fixed shaft 13.
and a second link 11B that rotatably connects the tip of the first link 11A and the lower end of the ball case 3, and the first link A is connected to the plunger of the electromagnetic solenoid 12 via a connecting rod. ing.

When the electromagnetic solenoid 12 serving as the driving means is excited, the first link 11A is pushed up about the shaft 13 from the position shown in FIG. 2a to the position shown in FIG. It is rotated from the rest position of a to the tilted position of FIG. 2b.

In addition, in order to confirm whether or not this ball case 3 has actually tilted, a ball case tilt detector 14 is used.
is provided near the shaft 13. In this embodiment, the ball sheath case tilt detector 14 is comprised of a microswitch having a normally closed contact, the actuator of which is pressed by a contact piece 99 provided on the first link 11A.

A winning device 1 arranged on the game board surface of the game board 15
The winning balls that have won 6A or the winning device 16B are collected in a collection gutter 17 provided on the back side of the game board 15, passed through a guide gutter 18, rectified one ball at a time in a line, passed through a winning pattern generating means 19, and were collected. It is collected through the gutter 20.

The overflow gutter 5C stores excess prize balls for the batted ball supply tray when the batted ball supply tray (not shown) provided on the front side of the pachinko machine is full of prize balls and batted balls. This is to divert the flow to The upper end opening of this overflow gutter 5C is open to the side wall of the discharge gutter 5.

FIG. 3 and FIG. 4 show rotary disks 21A, 21B,
This figure shows the structure of a winning mode generating means whose main components include a contact piece 28, a moder M, and the like.

This winning mode generating means 19 generates, for example, a first winning ball detection signal, which will be described later as a first winning mode, or
Either one of the second winning ball detection signals is output-controlled, and the first winning ball detection signal and the second winning ball detection signal are simultaneously output-controlled, for example, as a second winning mode.

The winning mode generating means 19 is a main guide channel 18A branched from the middle of the guide channel 18 that guides the prize balls.
and a rotary disk 2 which is provided downstream of the sub-guidance gutter 18B and transfers each prize ball to the ejection gutter 20.
1A, 21B, a detector 29A as a first winning ball detection means for detecting winning balls transferred by the rotary disk 21A, and a second winning ball detecting means for detecting winning balls transferred by the rotating disk 21B. Detector 29B
It has

A sub-guide gutter 18A is arranged in parallel with the main guide gutter 18A for transferring the winning balls 22 to the rotary disk 21A. The main guide gutter 18A and the guide gutter 18B are each formed to have a width that allows the winning balls to be rectified one by one in a line, and are arranged at a slope that allows the winning balls to flow down naturally.

Further, the sub-guide gutter 18B is connected to the main guide gutter 18A so that winning balls can be easily diverted to appropriate positions. In this connection, for example, as shown in FIG. 4, when the winning ball 22 connected to the main guide gutter 18A is connected to the position corresponding to the fifth winning ball from the winning ball that contacts the rotary disk 21A, the winning ball When 5 or more 22s occur, the winning ball 22 from the 5th ball
The balls flow down to the sub-guidance gutter 18B and flow down to the rotary disk 21B, and as will be described in detail later, two winning balls 22 are detected at the same time, and prize balls corresponding to the two winning balls are detected. ejected all at once. Therefore, by appropriately setting the connection position of the sub guide gutter 18B to the main guide gutter 18A, simultaneous processing of winning balls can be arbitrarily determined depending on the desired amount of winning balls generated.

In this example, in order to smoothly flow into the sub-guide gutter 18B, as shown in FIG.
There is a slight step on the bottom. This step 23
is formed slightly beyond the center of the width of the main guide gutter 18A from the sub-guide gutter 18B side, so that the winning ball 22 can easily roll over to the sub-guide gutter 18B side. Incidentally, the sub-guidance gutter 18B is not limited to the connection shown in the embodiment; for example, the connection is not limited to the connection shown in the embodiment.
It may be branched into a letter shape.

At the downstream ends of the main guide gutter 18A and the sub-guide gutter 18B, rotary discs 21A and 21B each having a concave portion 24 formed thereon for receiving one winning ball 22 are disposed, respectively. The rotation speeds of both rotary disks 21A and 21B are synchronized, and the formation positions of the recesses 24 are also made to coincide. In this example, as shown in FIG. 3, both rotary disks 21A and 21B are coaxially driven by a motor M. The recess 24 is formed to a depth that allows the winning ball 22 to partially fit therein, so that a portion of the winning ball 22 protrudes from the circumferential surface of the rotary discs 21A, 21B.

The rotation shafts 25 of the rotary discs 21A and 21B are preferably located slightly below the extension line of the bottom surfaces of the guide troughs 18A and 18B.

In addition, the actual rotary disk has a diameter of 40φ and three recesses arranged at equal intervals on the circumference, and the rotation speed of the motor M is
The speed is set at 15 rpm, and each rotary disk can process 45 winning balls per minute. Therefore, as in the example,
If two rotary disks 21A and 21B are installed,
It can process as many as 90 winning balls.

At the upper part of the circumferential surface of each rotary disk 21A, 21B, there is a detection lever 26A rotatable about the shaft 27,
26B's abdomen is placed on each rotary plate 21
It is made to face the circumferential surfaces of A and 21B. In the example shown in FIG. 3, the rotation center shafts 27 of the detection levers 26A and 26B are located on the main guide gutter 18A and sub-guide gutter 18B sides, respectively.

Each detection lever 26A, 26B has a contact piece 28 extending from the shaft 27 toward the guide gutter 18 side. At positions facing this contact piece 28, winning ball detectors 29A and 29B are provided, respectively, which are activated by the swinging of detection levers 26A and 26B, respectively. In this example, both winning ball detectors 29A, 29
B is a micro switch having a normally closed contact that turns ON when pressure is released by the detection levers 26A and 26B.

The lower surfaces of the abdomens of both the detection levers 26A, 26B are formed into an arc shape 26' that substantially corresponds to the curve of the circumferential surface of the rotary disks 21A, 21B, as shown in FIG. 6a, and as shown in FIG. 6b. When the winning ball half-fitted into the recess 24 contacts the lower surface of the detection levers 26A, 26B and pushes up the detection levers 26A, 26B, the winning ball 22 is prevented from falling out of the recess 24.

Also, if such an arc shape 26' is formed,
The detection levers 26A, 26B can be gently rocked in the vertical direction.

As shown in FIG. 6a, the guide trough 18 side of the arc 26' is formed larger than the circumferential surface of the rotating discs 21A, 21B so as to create a slight gap between the circumferential surfaces.
This prevents the winning balls 22 from falling off.

In addition, the detection levers 26A, 26B and the rotary disk 21 when the winning ball is not fitted into the recess 24
The contact area with the peripheral surfaces of A and 21B is made as small as possible to reduce the frictional resistance between them.

Winning ball 22 half-fitted into the above-mentioned recess 24
As the rotary disks 21A, 21B rotate, the detection levers 26A, 26A change from the state shown in FIG. 6a to the state shown in FIG. 6b.
26B, the collection gutter 20 is removed from the recess 24.
fall inside.

FIG. 7 shows another example of the winning ball detection device.

This winning ball detection device differs from the case shown in FIG.
is located slightly above the discharge gutter 20 side of the rotary disk 21,
The detection levers 26A and 26B are in contact with the circumferential surface of the rotary disk 21 on the discharge side.

The contact pieces 28 each extend laterally from the shaft 27 in an L-shape, thereby allowing the detection levers 26A, 2
6B creates a force that presses against the circumferential surface of the rotary disk 21. When the winning ball falls from the recess 24 of the rotary disk 21, the detection levers 26A and 26B are swung, and at this time the detector 29 under each contact piece 28
A and 29B turn on.

Referring again to FIG. 2, the ball sheath case 3 serving as a storage section is in a substantially vertical position, and in this embodiment is formed large enough to accommodate the number of prize balls that are multiples of the predetermined number of prize balls per winning ball. The tilting axis 9
is set above the ball sheath case 3, so that the amount of tilting on the lower end side is large.

The ball sheath case 3 of the embodiment has a capacity twice as large as the predetermined number of prize balls, and is formed so as to accommodate the prize balls in an orderly arrangement from its lower end to its upper end.

In the vicinity of the prize ball discharging means 10, in the embodiment, on the tilting direction side of the ball sheath case 3 (on the right side in FIG. 2), when the ball sheath case 3 is tilted, the ball sheath case 3 is relatively moved into the ball sheath case 3 by the tilting. A discharge prevention member 30 is provided with a prevention claw 31 that fits into the ball and prevents the discharge of a certain number of prize balls. Hereinafter, when the ball sheath case 3 is tilted, the position of the blocking claw 31 that receives the coming ball sheath case 3 while remaining stationary and relatively fits into the ball sheath case 3, and therefore the release prevention member 30 will be explained below. Ball Zaya case 3
The original position that acts on is called the first position.

The release prevention member 30 is pivotally attached to a shaft 32, and
It is freely retractable in a direction away from the ball sheath case 3 about the shaft 32, and the retracted position is such that at least when the ball sheath case 3 is tilted, the blocking claw 31 of the release prevention member 30 does not fit into the tilted ball sheath case 3. Hereinafter, the retracted position of the release prevention member 30 in which the blocking claw 31 cannot act on the storage portion will be referred to as the second position.

When the release prevention member 30 prevention pawl 31 is in the first position, the release prevention member 30 prevents the ball sheath case 3 from being inserted into the tilting ball sheath case 3.
It is set so that the prize balls in the game are located at positions where they can be divided into a predetermined number of prize balls.

The sphere case 3 of this embodiment shown in FIG.
Since twice as many prize balls are used, the position (first location).

Reference numeral 33 in the figure indicates a blocking means including a release blocking member 30, which includes a link mechanism 34 that operates to drive the release blocking member 30 independently of the tilting of the ball case 3, and a link mechanism 34 that operates the link mechanism 34. It has an electromagnetic solenoid 35 and the like as an electric drive source.

The blocking means 33 of this embodiment has a rear end fixed to the fixed shaft 36.
The tip of the first link 34A, which is pivotally attached to It is connected to the plunger. Therefore, when the electromagnetic solenoid 35 is excited to attract the plunger, that is, when the electric drive source is energized, the first link 34A rotates clockwise in FIG. 2 about the fixed shaft 36. move. This rotation causes the second link 34B to rotate the release prevention member 30 about its pivot or shaft 32. As a result, the release prevention member 30
Therefore, the blocking pawl 31 moves from the first position shown in FIG. The ball sheath case 3 moves (retreats) in substantially the same direction as the tilting direction of the ball sheath case 3 to the second position shown in FIG.
When the ball is tilted, the state of the ball sheath case 3 is changed to a position where it cannot prevent the release of the prize ball.

Note that a release prevention member 30 is provided near the fixed shaft 36.
Release prevention member tilt detector 3 for detecting the backward state of
7 has been temporarily installed. Specifically, the first link 34
A contact piece 38 is attached to A, and a micro switch having a normally closed contact is used as the detector 37.
In the first position shown in Figure a, the contact piece 38 is adapted to press against the actuator of this microswitch. Therefore, the blocking means 33 moves from the first position to the second position.
When the state changes to the position, the contact piece 38 releases the pressure on the actuator, thereby turning on the micro switch as the detector 37.

FIG. 8 is a block diagram showing, for example, an electric circuit as a control means for the prize ball discharging device.

Reference numeral 29A in the figure is a detector serving as a first winning ball detection means that outputs a first winning ball detection signal by detecting winning balls generated during the game.
Further, reference numeral 29B is a detector serving as a second winning ball detection means that outputs a second winning ball detection signal by detecting winning balls generated during the game.

Detector 2 as first and second winning ball detection means
9A and the detector 29B each have a differentiating circuit 3.
9A and 39B are connected. This differential circuit 3
From 9A onwards, when the affiliated winning ball detector 29A detects a winning ball, it outputs an H level output signal, that is, a first winning ball detection signal. Similarly, the winning ball detector 29 belonging to the differential circuit 39B
When B detects a winning ball, it outputs an H level output signal, that is, a second winning ball detection signal.

Every time a winning ball is detected by at least one of the winning ball detectors 29A or 29B, the differentiating circuit 3
A winning ball detection signal of H level is generated at 9A and 39B, and this signal sets a flip-flop 41 via an OR gate 40. A driver circuit 42 is connected to the set output terminal of this flip-flop 41.
An electromagnetic solenoid 12, which is a driving source for tilting the ball sheath case 3, which is the above-mentioned storage section, is connected through the solenoid. Therefore, the ball zaya case 3 can be used for each case, for example, in the case where only one winning ball is detected, that is, in the case of the first winning mode, and in the case, for example, when two winning balls are detected at the same time, that is, in the case of the second winning mode. 1
The ball is tilted only once by the tilting drive device 10 as the prize ball ejecting means.

A timer 44 is triggered by the leading edge of the set output of the flip-flop 41 via the differentiating circuit 43, and generates an H level output after a predetermined timer period has elapsed. The predetermined timer time mentioned here is the time width required to release all the prize balls in the ball spread case 3 plus a slight time margin.

Reference numeral 45 is an AND circuit in which the output of this timer 44 and the output of the ball case tilt detector 14 are two inputs.
It is a gate, generates an output when both outputs are at H level, and resets the flip-flop 41. That is, when the above-mentioned timer time elapses, since the output of the ball shear case tilt detector 14 is always generated during operation, an H level output is generated at the AND gate 45, the flip-flop 41 is set, and the electromagnetic solenoid 12 is demagnetized. This completes one cycle of the tilting operation of the ball case 3.

In this way, in the above embodiment, the prize ball discharging device 10 is operated based on the detection signal of either the first winning ball detection signal or the second winning ball detection signal (for example, the first winning mode). It is configured to release a predetermined number of prize balls per ball.

Next, based on both the first winning ball detection signal and the second winning ball detection signal (for example, second winning mode), the prize ball discharging device 10 is activated to release a number of winning balls larger than the predetermined number. The configuration for emitting will be explained. In this embodiment, the control means is mainly composed of a flip-flop 41, an AND gate 45, a flip-flop 47, and the like.

First, reference numeral 46 in the figure indicates each winning ball detector 29.
Both differential circuits 39A, connected to A and 29B,
This is an AND gate with two inputs being the output from 39B. This AND gate 46 generates an output signal and sets the second flip-flop 47 when two winning balls are simultaneously detected by the winning ball detector 29A and the winning ball detector 29B (for example, in the second winning mode). do.

The set output terminal of the flip-flop 47 is
An electromagnetic solenoid 35 is connected via a driver circuit 48 as an electrical drive source that drives the above-mentioned release prevention member 30 to change its state. or,
A notification lamp 50 is connected via a driver circuit 49.

Therefore, the winning ball detector 29A and the winning ball detector 2
When a winning ball is detected at the same time as 9B (for example, in the second winning mode), the electromagnetic solenoid 35 is energized (energized), and the release prevention member 30 is activated via the link mechanism 34 as shown in FIG. 2b. converted to a second position. When the release prevention member 30 is located at this second position, even if the ball sheath case 3 tilts, the prevention claw 31 of the release prevention member 30 will not fit into the case 3, so the ball sheath case 30 will not fit into the case 3. 3
If the ball tilts once, all prize balls within it will be released. The fact that twice the number of prize balls is being released is notified to the player by simultaneously lighting up the notification lamps 50.

Reference numeral 51 is an AND gate having two inputs: the output of the timer 44 and the output of the release blocking member tilting detector 37. That is, when the timer time of the timer 44 elapses, the output of the winning ball detector 37 is always output while the release prevention member 30 is in operation, so the output is AND.
An H level output is generated at gate 51 to reset flip-flop 47.

In the embodiment, the timer 44 is shared for resetting both the flip-flop 41 and the flip-flop 47, but a dedicated timer is provided for resetting the flip-flop 47, and the set output of the flip-flop 47 is used to run the timer through a differentiating circuit. The output of the timer and the output of the release prevention member tilting detector 37 are connected to the AND gate 51.
2 inputs may be made.

Next, the prize ball release action will be briefly explained in cases where the number of prize balls is one or two. First, two winning balls 22, one from the main guide gutter 18A to the rotary disk 21.
When the other ball is inserted into the recess 24 of the rotary disk 21B from the sub-guide gutter 18B, the protruding spherical surfaces of both winning balls 22 are inserted into the recess 24 of the rotary disk 21A and the rotary disk 21B.
The detection lever 26A and the detection lever 26B are simultaneously pushed up by the synchronous rotation of the levers B. The swinging of the detection levers 26A and 26B is immediately detected by the winning ball detectors 29A and 29B (for example, in the second winning mode). That is, in this embodiment, the contact piece 28 of the detection lever 26 separates from the actuator of the microswitch, turning the microswitch ON. Then, an output is generated in the AND gate 46,
A flip-flop 47 is set, and an electromagnetic solenoid 35, which is an electrical drive source, is connected via a driver circuit 48.
is energized and energized, retracting the emission blocking member 30 and converting it to the second position.

On the other hand, an output is also generated from the OR gate 40, which sets the flip-flop 41 and excites the electromagnetic solenoid 12, which is the driving source for the prize ball discharging means 10, through the driver circuit 42. As a result, the link mechanism 11 tilts the ball sheath case 3, and all the prize balls, which are twice the predetermined prize balls reserved in the ball sheath case 3, are released at once (FIG. 2b).

Next, one winning ball passes through either the main guide gutter 18A or the sub-guide gutter 18B, and then passes through the rotating discs 21A, 21B.
In the case of fitting into any of the recesses 24, that is, in the case of the first winning mode, for example,
Or detection lever 26A or 26B of rotary disk 21B
Only one side swings. As a result, no output signal is output to the AND gate 46. Therefore, the blocking means 33
Since the electromagnetic solenoid 35, which is the electrical drive source, is left in a non-energized state, the discharge prevention member 30 of the prevention means 33 remains in its current state without retreating.

However, since an output signal is generated in the OR gate 40, the electromagnetic solenoid 12 is energized, and the ball sheath case 3 as a storage section is tilted via the link mechanism 11. Due to this tilting movement, the blocking claw 31 of the release blocking member 30 fits into the ball sheath case 3, and the predetermined prize balls per winning ball corresponding to the upper half of the ball sheath case 3 are stopped, and only the predetermined prize balls in the lower half are stopped. is released.

In addition, in order to speed up the return of Ball Zaya Case 3,
Although the return spring 8 is attached to the ball case 3, it may be returned to the vertical position by its own weight alone.

Further, when there is a shortage of prize balls, it is preferable to interpose a prize ball shortage detector in the motor drive circuit of the rotary discs 21A, 21B. For example, a micro switch with a normally closed contact that is turned ON by the weight of the prize ball flowing down in the middle of the prize ball outlet gutter 4 is used, and as shown in FIG. Insert it.
Since the lead-out gutter 4 of the embodiment is configured in two rows,
In Fig. 9, switch contacts SW1 and SW of the prize ball shortage detector provided for each outlet gutter 4 are shown.
2 are connected in series. As a result, when there is a shortage of prize balls in any of the guide channels 4, one of the winning ball detectors is turned OFF, and the rotating discs 21A, 21
Motor M that drives motor B can be stopped.

The above embodiment is a case in which twice as many prize balls as the normal number of balls are placed in the ball case 3. However, the present invention is not limited to this, and the present invention can accommodate this depending on the number of winning balls that are paid at least three times as many winning balls and are simultaneously detected by a plurality of winning ball detectors, that is, the winning mode. It is also possible to release prize balls as many as the number of balls in one tilting motion.

In addition, in the embodiment, the number of prize balls that is an integral multiple of the number of winning balls that are simultaneously detected is discharged in response to the number of winning balls that are simultaneously detected. Then, the above prize ball release control may be performed in response to winning signals having different winning values.

Next, an example will be described in which three times as many prize balls can be released.

In FIG. 10, the ball case 3 is configured to have a length that can accommodate three times the predetermined number of prize balls corresponding to one winning ball, and exactly the number of prize balls that is one and twice the number of prize balls. Outside of the first release prevention member 30, which is equipped with a blocking claw 31 that fits into the ball sheath case 3 at the boundary position, there is a ball prevention member 30 that prevents double and triple prize balls from entering the ball sheath case 3 at the boundary position. a second with a pawl 31';
A release prevention member 30' is provided.

The structure of the blocking means 33' of the second release preventing member 30' is the same as the blocking means 33 described above, and includes the releasing preventing member 30 having the blocking claw 31, a link mechanism 34', and an electromagnetic drive source as an electric drive source. Soleido 3
5' etc. Second release prevention member 3
The tilting of 0' is confirmed by the tilting detector 37'.

The rotational center axis 9 of the ball case 3 is the first and second
It is located between both release prevention members 30, 30'. For this reason, the first release prevention members 30 are located on opposite sides of the ball case 3 in FIG. 10.

Regarding the detection of winning balls, the rotary disk type winning ball detection device 19 shown in FIG. 3 or 7 is expanded. For example, as shown in FIG. 11, a third rotary disk 21C is provided in the same manner as the other rotary disks 21A and 21B, and a third guide gutter branch path 18C is provided facing the third rotary disk 21C. Similarly to the detection levers 26A and 26B, a third winning ball detector 29C attached to the rotary disk 21C is provided to be activated.

In the winning ball detection device shown in FIG. 11, the main guide trough 18
A, sub-guide gutter 18B, and sub-guide gutter 18C's branching points are not distinguished in terms of ease of flow. Therefore,
When one winning ball is sent for the first time, it is not certain which of the main guide gutter 18A, sub-guide gutter 18B, and sub-guide gutter 18C the winning ball will be guided to. However, this inconvenience is resolved in the electric circuit described below.

Now, when the above winning ball detection device and winning ball releasing means are used, when the number of winning balls detected is one (for example, the first winning mode), and when two winning balls are detected (for example, the second winning mode),
Winning method), in the case of 3 prizes, 1x, 2x, respectively.
In order to release three times the number of prize balls, the first and second
It is necessary to control both the release prevention members 30, 30' by an electric drive source as shown in the table shown in FIG.

FIG. 12 is a circuit diagram of a control means for performing control according to the table of FIG. 13, and the same components as in FIG. 8 are given the same reference numerals.

Symbols 52, 53, and 54 in the figure represent arbitrary two output signals and the remaining one among the output signals from the differentiating circuits 39A, 39B, and 39C that belong to each winning ball detector 29A, 29B, and 29C, respectively. The inverted signal of the output signal is input, and therefore, when two winning balls are detected by the winning ball detector at the same time (for example, in the second winning mode), an output signal is generated. Reference numerals 56, 57, and 58 in the figure indicate inverters for producing the above-mentioned inverted signals.

The output signal of each AND gate 52, 53, 54 is
Through the OR gate 55, the flip-flop 47
is sent to the set input terminal of the flip-flop 47, causing the flip-flop 47 to be set. A driver circuit 48 for the electromagnetic solenoid 35 of the first emission prevention member 30 is connected to the output terminal of the flip-flop 47 via an OR gate 59, and a first input terminal of the OR gate 59 and a driver circuit for the notification lamp 50 are connected to each other. is connected. This notification lamp 50 serves to notify that the double emitting operation is being performed.

The AND gate numbered 60 in the figure is the differentiator circuit 39
This is an AND gate that takes the output signals from A, 39B, and 39C as three inputs, and outputs an output signal when three winning balls are detected by the detector at the same time.

Reference numeral 61 denotes a flip-flop which is set by the output signal of this AND gate 60, and is set by the output of the AND gate 62 which has two inputs: the output of the second release blocking member tilt detector 37' and the output of the timer 44. It will be reset. The driver circuit 6 is connected to the set output terminal of the flip-flop 61.
3 to the electromagnetic solenoid 35' of the second release prevention member 30, and a driver circuit 64 to the notification lamp 65. Notification lamp 65
serves to notify that the triple emission operation is in progress.

Furthermore, an OR gate 59 is connected to the output terminal of the flip-flop 61 for the purpose of energizing the electromagnetic solenoid 35 of the first release prevention member 30 during triple release.
The second input terminal of is also connected.

Now, only one winning ball is detected by the winning ball detector 29A, 2
When detected in either 9B or 29C (for example, in the first winning mode), the flip-flop 41 is set via the OR gate 40, the electromagnetic solenoid 12 is energized, and the ball sheath case 3 is rotated counterclockwise in FIG. tilt to. In the case of one winning ball, both release prevention members 30, 30' remain in the normal position shown in FIG. 10. Therefore, with the tilting, the blocking claws 31, 31' of both the release blocking members 30, 30' fit into the ball sheath case 3, and by the action of the blocking claw 31 located at a lower position, the The number of prize balls is released from the ball case 3.

Only two winning balls are detected by the two winning ball detectors 29A and 29B, or by the winning ball detectors 29B and 29C.
or when it is detected by the winning ball detectors 29A and 29C (second winning mode), an output signal appears in any of the AND gates 52, 53, and 54,
This signal passes through OR gate 55 and sets flip-flop 47.

Therefore, the electromagnetic solenoid 35 is energized and the first
The release prevention member 30 is retracted from the first position to the second position.

In this case, three winning ball detectors 29A, 29
Since any one of B and 29C has not detected a winning ball, no output appears at the AND gate 60. Therefore, the second release prevention member 3
The electromagnetic solenoid 35' at 0' is not energized and the second release blocking member 30' is in the normal position.

When the ball case 3 tilts, the ball case 3
The prize balls inside are partitioned only by the blocking claw 31' of the second discharge preventing member 30' in the normal position, and twice the number of prize balls stored below this are separated by one tilting movement. released in At this time, the lamp 50 lights up to inform the player that the double release operation is being performed.

Three winning balls at the same time 3 winning balls detector 29
When detected at A, 29B, 29C,
An output is generated at AND gate 60 and flip-flop 31 is set. The output of this flip-flop 61 is connected to the OR gate 59 and the driver circuit 4.
At the same time, the electromagnetic solenoid 35 of the first release blocking member 30 is also excited via the driver circuit 63, and the electromagnetic solenoid 35' of the second release blocking member 30' is also excited via the driver circuit 63.

Therefore, when three winning balls are detected at the same time, both release prevention members 30, 30' are moved to the retreat position, and as a result, when the ball sheath case 3 is tilted, the total number of winning balls accommodated therein, that is, 3. All double prize balls will be released. The lamp 65 indicates that this is the triple ejection operation.

Incidentally, the flip-flop 47 and the flip-flop 61 are activated by the output of the timer 44 for a time sufficient to eject all the prize balls in the ball sheath case 3.
It is reset via AND gate 51 or AND gate 62.

The above is a prize ball ejection device capable of ejecting up to three times as many balls, but similarly to this example, the length of the ball sheath case 3 is increased, a release prevention member is added, and all the release prevention members are appropriately selectively removed. By providing a control circuit to operate the system, it is possible to change the system so that four times as many prize balls or more can be ejected.

(Effects of the Invention) As described above, in the first winning mode, the present invention drives the prize ball ejecting means and at the same time de-energizes the electric drive source of the blocking means to convert the ejection blocking member to the first position. While the minimum number of prize balls is released as the number of prize balls, in the second winning mode,
The structure is such that the prize ball discharging means is driven, and the electric drive source of the blocking means is energized to convert the discharge preventing member to the second position, thereby ejecting more prize balls than the above-mentioned minimum number. A variable prize ball ejecting device that can emit balls in multiple types of prize balls in accordance with the winning manner of batted balls can be assembled vertically on one side on the back side of the game board, for example, to miniaturize the structure. be able to. As a result, a large gap can be secured on the back side of the collecting gutter on the other side of the variable prize ball discharge device, and the rear part of the large prize device attached to the surface of the game board can be freely exposed to this gap.

Furthermore, the blocking means that determines the number of prize balls to be emitted according to the present invention operates so as to emit the minimum number of balls when the electric drive source is in a non-energized state, and when the electric drive source is in a energized state, a number of balls is greater than the minimum number. Since it is configured to operate so as to eject a number of prize balls, it is equipped with a variable prize ball ejecting device that ejects more prize balls than the minimum number of balls when the electric drive source of the blocking means is in a de-energized state as in the past. For example, a pachinko parlor that has installed pachinko machines may set a predetermined number of balls (min. number)
It is illegal to intentionally remove the connector of the wiring connected to the electric drive source of the blocking means, in order to release more prize balls than the minimum number of balls, without violating the law. Acts can be deterred before they occur.

Therefore, since the pachinko machine equipped with the variable prize ball ejecting device of the present invention has a structure that makes it difficult for pachinko parlors to commit the above-mentioned illegal acts, it can greatly contribute to the healthy development of pachinko games.
