A certain number of pachinko balls for safe balls and winnings (also called prize balls)
The present invention relates to a prize ball discharging device that discharges prize balls.

[0002]

2. Description of the Related Art In general pachinko machines and arrangement ball machines known as one of typical examples of this type of gaming machine,
As means for discharging a predetermined number of pachinko balls in response to winning of a safe ball or a symbol combination generated during a pachinko game, a prize ball discharge device is implemented on the prize ball discharge path of the mechanism set board on the back side of the machine. ing. This prize ball discharge device is based on the premise that safe balls are detected one by one or winning is detected one condition at a time.
The following types have been proposed as types that are controlled based on a prize ball discharge command for each detection related to these detections.
It was also implemented.

[0003] That is, a ratchet wheel-shaped ball feeder in which a large number of ball receiving portions are formed and arranged at equal pitches on the outer periphery and faces a passage for a prize ball, an electromagnetic solenoid and a lever, or a motor and a gear. And various types of electric control mechanism sections. Then, before the energizing operation of the electric control mechanism, the ball feeder is stopped and held, and the ball feeder is rotatably released when the electric control mechanism is energized by the winning ball discharge command. As a result, the same board is rotated over a predetermined angle (including one rotation) while receiving the prize balls in the passage at each ball receiving portion, and discharges a predetermined number of prize balls.

The prior arts relating to the above-described electrically driven prize ball discharging device and ball feeding device include, for example, JP-A-54-34939, JP-A-57-45880, and JP-A-61-76181. And Japanese Utility Model Publication No. 60-20282 and Japanese Utility Model Publication No. 3-49732.

[0005]

However, in the above-described conventional electric control type prize ball discharge device (ball-starting device), when the ball feeder and the electric control mechanism are associated with each other, the rotation / stop for the ball feeder is performed. Switching means and positioning stop means,
Further, it is necessary to additionally provide a rotation detecting means for the ball feeder and a drive control means for the electric control mechanism, so that the whole apparatus becomes large and complicated. For this reason, there is a problem that it is difficult to apply this kind of device to the mechanism set board which is limited in space and size. In this type of apparatus, in which the ball feeder is rotatable in a predetermined angle unit, the variable situation of the number of prize balls to be ejected is determined by, for example, every 1/3 rotation or half rotation of the ball feeder. Can be changed to a fixed number of pieces by one rotation and a fixed number of pieces by one rotation or half a rotation. However, in this embodiment, it is extremely difficult to change the classification in a single ball unit within the range of the specified number permitted as a prize ball. There was a problem of low quality.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems inherent in the above-mentioned conventional prize-ball discharging device, and has been proposed to solve the problem in a favorable manner. While the ball feeding member for the ball is stopped and held by using a permanent magnetic force generated at all times, the ball is controlled to be rotatable using an electromagnetic force acting in a direction in which the permanent magnetic force cancels out. The present invention provides a prize ball discharge device for a pachinko game machine that discharges a predetermined number of prize balls for winning or winning, facilitates miniaturization and handling of the entire device, and enables accurate prize ball discharge operation. The purpose is to do.

Control mechanism including a permanent magnet for stopping magnetic attachment of the rotor to the stator and a electromagnetic force generating unit for canceling the magnetic force of the permanent magnet in a case body having a spherical passage connected to a discharge path for use Department and
The ball feeder, which is made rotatable integrally with the rotor of the electric control mechanism under conditions for receiving the prize ball in the ball passage, and the prize balls ejected by the rotation of the ball feeder are checked one by one. Before the emission command is transmitted from the electric control device, the non-energized pulse output condition for the electric control mechanism unit is used to stop the magnetic attachment of the rotor with the magnetic force of the permanent magnet. The ball feeder is restrained and held non-rotatably. On the other hand, when the discharge command corresponding to the detection signal of the safe ball or the winning signal is transmitted, the electromagnetic force generation unit is controlled based on the power supply pulse output condition to the electric control mechanism. When the pachinko ball is discharged in the rotated state of the ball feeder by releasing the rotor by the canceling action of the electromagnetic force generated by the electromagnetic force and the permanent magnetic force, when the count completion detection signal of the discharged prize ball is input by the detecting means. In, energizing pulse output for the electric control mechanism by the ejection command is stopped, characterized by being configured to terminate the prize balls ejection actuation of the times by the operation stop of the mechanical part.

[0009] In such a prize ball discharging device, before sending the prize ball discharging command from the electric control device,
The ball feeder is stopped and held together with the rotor using the permanent magnetic force constantly generated by the electric control mechanism to prevent the prize balls from being discharged. Under this condition, when a safe ball is detected or a discharge command is issued when winning is established, the permanent magnetic force is canceled by using the electromagnetic force generated under the energized pulse output condition to the electric control mechanism, thereby releasing the motor. The ball feeder is rotated while receiving the prize ball together with the rotated rotor, and discharges the prize ball. Then, at the end of the detection of the expiration of the discharged prize ball by the detecting means, the output of the energizing pulse according to the discharge command is stopped, the ball feeder is stopped and held together with the rotor, and the current prize ball discharge operation is ended.

_{On the} basis of the discharge command issued from _{1, the} prize balls for each safe ball can be separately discharged in a plurality of predetermined numbers. FIG. 4 shows the basic configuration of the device M.
As shown in FIG. 6, a case body 51 defining a ball passage 55 communicating with the prize ball path described above, and an electric control mechanism unit housed in the case body 51 and energized in response to a discharge command. 57 and a ratchet wheel-shaped ball feeder 70 mounted on the outer periphery of a rotor 67 which is a rotatable movable body in the mechanism 57
And detection means 75 and 76 for prize balls, and the whole is unitized for each case body 51 and can be handled.

The device M of this embodiment will now be described for each of the components described above.
A pair of inner and outer frames 52, 52 formed of synthetic resin are screwed and aligned with each other to form a substantially rectangular cube. Between them, it is positioned and set on the main body 28 of the mechanism setting board 27 with screws or the like. A housing chamber 53 is defined in both frames 52, 52, while a spherical passage 55, which is vertically extended in the gutters 54, 54, is defined, and the upper end inlet and the lower end outlet thereof are sent out. The gutter 38 and the first prize ball discharge path 39 are respectively aligned and communicated. It is desirable that the case body 51 be opaque so as to suitably block external light (illumination). The accommodation chamber 53 has one side open and communicates with a decompression guide 56 formed at the center of the ball passage 55. The decompression guide section 56 appropriately reduces the pressure of the prize ball, and can always smoothly guide the prize ball toward the ball feeder 70 (see FIG. 5).

The electric control mechanism 57 rotates the ball feeder 70 by using a permanent magnetic force that is constantly generated inside and an electromagnetic force that is generated when energized and acts in a direction to cancel the permanent magnetic force. -Stopping is controlled. As a basic configuration, as shown in FIG. 4, a stator (iron core) 58 made of a magnetic material having a cylindrical shape, and projections for concentrating a permanent magnetic force disposed on both ends of the stator 58 on the outer periphery. Parts 60,60
A pair of inner stators 59, 5 of magnetic material with
9, a ring-shaped permanent magnet 61 interposed between the stator 58 and one of the inner stators 59, and a pair of aluminum-made lid plates 62, 62 disposed outside the inner stators 59, 59 on both sides. Are tightened and connected by a common bolt 63. Then, a coil 65 is wound around a bobbin 64 made of Duracon material on the outer periphery of the stator 58,
6 and a rotor 6 made of a cylindrical magnetic material having ridges 68, 68 for concentrating permanent magnetic force formed in an inner peripheral hole.
7 is inserted between the lid plates 62 and 62 and supported by bearings 69 and 69.

In the mechanism 57, both ends are positioned and supported by the supporting portions of the frame bodies 52, 52 on each side of the case body 51, and are accommodated and set. There is connected to the first control device C ₁ of the drive circuit section (pulse output unit). Under this condition, before energization (before operation), a magnetic force (permanent magnetic force) constantly generated from the permanent magnet 61 and applied in one direction is generated by the inner stator 5.
The protrusion 67 of the rotor 9 and the protrusions 68 of the rotor 67 are intensively operated so that the rotor 67 is always magnetically held at the stop position. On the other hand, during energization (pulse output) in response to the discharge command, the magnetic force (the electromagnetic force) generated from the electromagnetic force generation unit 66 acts in a direction to cancel the permanent magnetic force to release the rotor 67. (Magnetization release). Accordingly, the rotor 67 is configured on the assumption that the ball feeder 70 described later receives the pressure (weight) of the winning ball.
The ball is smoothly rotated together with the ball feeder 70.

In the above-described electric control mechanism 57, at least one of the inner stator 59, the cover plate 62 and the frame 52 has an insertion opening for a coil 65 drawn out from one end of the bobbin 64. . The inner stators 59, 59 on both sides are formed in a gear shape as a whole by overlapping a plurality of the stators, and the inner peripheral hole of the rotor 67 is formed as a spline-shaped hole. , 68 are arranged at the same pitch (24 at intervals of 15 °), and their magnetic force concentrating surfaces oppose each other with a small gap (see FIGS. 7 and 8).

The ball feeder 70 is made of synthetic resin and integrally formed with a row of ball receiving plates 72 in the form of a ratchet at the center of the outer periphery of a cylindrical portion 71. The control mechanism 57 is positioned and fixed closely to the outer periphery of the rotor 67. In the ball receiving board 72, the center in the width direction is aligned with the center of the ball passing through the ball passage 55, and the prize ball 1
An arc-shaped receiving portion 73 suitable for an individual and a claw portion 74 for partitioning are formed and arranged at an equal pitch in the circumferential direction (12 at intervals of 30 °). A part of the ball receiving board 72, that is, the receiving part 73 and the claw part 74, appropriately faces the ball passage 55 while being housed in the housing chamber 53 of the case body 51. In this state, as illustrated in FIGS. 5 and 6, the tip of one claw 74 is aligned with reference to a horizontal center line (XX) passing through the centers of the electric control mechanism 57 and the ball feeder 70. Then, the upper receiving portion 73 is aligned with the depressurizing guide portion 56 of the ball passage 55, and the prize ball can be discharged from the downstream side with reference to the alignment position of the claw portion 74.

As shown in FIGS. 7 and 8, the positional relationship between the protrusion 60 and the protrusion 68 in the electric control mechanism 57, and the receiving portion 73 and the claw 74 of the ball feeder 70 is as follows. They are arranged at an angle ratio of 1: 2. Electric control mechanism unit 57 from the first control device C ₁ in relation to this

Is set to

As a means for confirming a prize ball, first and second predetermined portions of the gutter portion 54 of the case body 51 are provided.
Detecting means 75 and 76 are disposed. The first detecting means 75 is for detecting the presence or absence of a prize ball to be passed into the ball passage 55 and an appropriate accommodation state, and the second detecting means 76 is for detecting the sphere of the ball feeder 70. It is intended to count and detect the prize balls discharged by the rotation. And both of means 75 and 76, the first control device is connected to a discharge command control circuit unit side of the C _1, it is a spherical chromatic detection condition (ON) at the time of detecting winning balls, winning balls for a predetermined time In the state where no ball is detected, the ball no-detection condition (OFF) is set. Thus the discharge command from the device C ₁ with a first detecting means 75 spherical chromatic detection condition (ON) is capable originating and ball no detection condition
(OFF) stops or interrupts the discharge command. Also the second
In Moto that every count detection signals of the detection means 76 is input to the device C _1, when the count detection signal is not input from the halfway, the discharge command is interrupted and the count expiration detection signal is input At this point, the control is set so that the discharge command is terminated.

It is to be noted that both of the detecting means 75 and 76 are of the photoelectric switch type, for example. In the first detecting means 75, a prize ball (see FIG. 5 (the solid line) can be detected as a target, and the second detecting means 76 detects the horizontal center line X-
An example is shown in which an award ball is set so that it can be detected below a discharge reference position for X. The means 75 and 76 and the switches 17, 24, 25 and 33 are controlled by the control devices C ₁ and C ₂ as shown in FIG.

Here, the entry and exit states of the prize balls in the working state of the prize ball discharge device M of the present embodiment will be additionally described, from the storage tank 36 of the mechanism set board 27 to the straightening gutter 37 and the delivery gutter 38. Under the condition that the prize balls are passed in a rosary connection state, the prize balls entering from the entrance of the ball passage 55 are deflected and guided to the ball feeder 70 side while being appropriately decompressed by the decompression guide section 56. , Receiving part 73 of ball receiving board 72
Accepted to. Then, as shown in FIG. 5, with the claw portions 74 aligned with the horizontal center line XX,
The most advanced ball (most downstream ball) is not discharged while being received by the receiving portion 73, but is discharged from the lower receiving portion 73 of the claw portion 74. In this state, the leading prize ball received by the receiving portion 73 is detected by the first detecting means 75. The pressure (load) of the prize ball reaching the upstream side of the pressure reducing guide portion 56 always acts in the hanging direction so that a large pressure does not act on the prize ball located in the guide portion 56. As a result, the ball feeder 70 can be lightly pressed and rotated while receiving an appropriate pressure including the weight of the prize ball on the ball receiver 72.

[0027]

Next, the operation of the prize ball discharging device in the pachinko gaming machine according to the embodiment will be described.

In the above-mentioned pachinko machine P, a required game operation is performed in a state provided for a game, so that the operation of the hitting ball launching device 8 and the operation of the ball feeding device 6 are coordinated. Pachinko balls (game balls) in the ball tray 5 are driven one by one from the firing rail 10 into the game surface 14 of the game board 12 to develop the game. The game balls that enter during the opening operation of the out port 15, the respective winning tools 16, 18 and the grand prize device 20 are finally discharged from each path of the mechanism set board 27 as out balls and safe balls. On the other hand, as a reward for the safe ball, all safe balls are detected and stopped by the safe ball processing device 32 one by one.
Based on the discharge command prize balls to be transmitted from the control device C ₁ (payout control information), winning balls discharge device M of the embodiment is set Conditions
It is operated once every hour to discharge a predetermined number of prize balls.

The control operation of the prize ball discharging device M of the present embodiment relating to the discharge of the prize ball to each safe ball described above will be described below.

First, as an example of a basic control operation of the device M, before the discharge command is issued from the first control device C ₁ , the electric control mechanism 57 is not energized, and the electric control mechanism 57 shown in FIG. Stopped. For this reason, the magnetic force (permanent magnetic force) constantly generated from the permanent magnet 61 in the mechanism unit 57
Acts intensively between the projection 60 and the ridge 68 to stop the magnetic attachment of the rotor 67.
0 is stopped and held non-rotatable with the ball receiving board 72 receiving the prize ball. Under this condition, the first control device C ₁ is set on the assumption that the first detection means 75 is in the ball detection condition (ON).
When a discharge command is transmitted from the controller, a pulse of the set condition is supplied to the electromagnetic force generator 66 via the coil 65 as an output in response to the command. As a result, the magnetic force (electromagnetic force) generated from the generator 66 acts in a direction to cancel the permanent magnetic force, and the magnetic force of the rotor 67 is released.

As a result, the ball feeder 70 is brought into a free state in which it can be rotated, and the prize ball in the ball passage 55 is lightly received and rotated while being received in each of the receiving portions 73 of the ball receiving board 72.
Discharge one ball at a time.

In the above-described prize ball discharging process, the second detecting means 76 counts and detects the prize balls discharged from the beginning of the discharge by the rotation of the ball feeder 70 one by one, and outputs the signal. input to the first control device C _1. This under the count from the means 76 reaches the expiration detection condition corresponding to a predetermined number worth of discharge prize balls, In conjunction with the signal input, power output for discharge command of the first control device C ₁ in the batch As a result, the end of the transmission of the pulse of the set condition to the electromagnetic force generating unit 66 is stopped.
The generation of the electromagnetic force from the generator 66 is stopped and disappears. As a result, the state is restored to the state where only the permanent magnetic force is generated, and the magnetic force acts intensively on the protrusions 60 and the protrusions 68 to stop the magnetic attachment of the rotor 67 again. The ball 70 is kept in the original non-rotatable state, and stopped while receiving the prize ball on the ball receiving board 72. As a result, one discharging operation is completed, and a predetermined number of prize balls for the safe ball are discharged. In connection with this, in the safe ball processing device 32, the electromagnetic solenoid 3
By the operation of 4, the safe ball is released from the stopper 35 and is discharged.

That is, in the above-described prize ball discharge control operation, the pulse of the set condition is set in advance under a condition (P × N) that matches the number N of prize balls acquired (discharged) for one safe ball. Have been. Under this condition, under the input condition of the detection signal of the presence of a sphere by the first detection means 75, 1
The ball feeder 70 is rotated by one pitch by the pulse output of the first ball (the first ball) and ejects the first ball (most preceding ball). On the other hand, after the count detection signal is input by the second detection means 76, two pulse outputs (for the second ball) are transmitted, and the ball feeder 70 is rotated by the next pitch to eject the next ball. And
After that, the prize balls are discharged one by one by the rotation of the ball feeder 70 by the next pulse output after the input of the count detection signal. The input point count expiration detection signal described above, the discharge command from the first control device C ₁ (energized Output)
Is stopped, and the current prize ball discharge control operation ends.

Next, as an example of the application control operation of the apparatus M, a description will be given of each operation in a case where a different number of prize balls are ejected for each safe ball, in other words, when the number of prize balls is changed and set in multiple ways. I do. That is, as an example of the number of prize balls, (A) a certain small number N ₁ (for example, N ₁ =
(7), (B) Each switch 24, 25 of the big winning device 20
For the B-type safe balls detected in the above, a certain number of N ₂ (for example, N ₂ = 10), (C) C entered the other prize tool 18 and detected by the switch 33 of the safe ball processing device 32 Seed safe sphere
A case where a certain number N ₃ (for example, N ₃ = 15) is set for (except for the type A and type B safe spheres).

[0035] In this number setting example, the first control device C ₁ is the respective discharge command transmitted from (the A type, B type,
As illustrated in FIG. 7, FIG. 8, and FIG. 10, for the pulses of the setting conditions corresponding to the discharge command transmitted based on the priority order in which the detection signal of each of the C-type safe spheres has been detected, In the case of the above item (A), P × N ₁ , in the case of the item (B), P × N ₂ , and in the case of the item (C), P × N ₃ . In each control operation, the electric control mechanism 57 is energized based on the pulses of these set conditions, and the rotor 67 is released by the respective pitch angles due to the cancellation of the permanent magnetic force and the electromagnetic force. . At the same time, the ball feeder 70 is lightly rotated under pressure.
N ₁ = 7 balls from the ball receiver 72 according to the rotated condition,
Each of N ₂ = 10 and N ₃ = 15 prize balls is accurately classified and discharged quickly.

As described above, in the prize ball discharging device M of the present embodiment, the first example is based on the point in time when all the safe balls generated in the pachinko machine P are detected by the switch 33 of the safe ball processing device 32 as a reference. Given an input of the sphere chromatic detection signal by the detection means 75, the pulse setting conditions corresponding to a discharge command transmitted from the first control unit C _1, the conditions of each input of the count signal detected by the second detection means 76 Thus, the required number of prize balls can be appropriately discharged only by controlling the output according to the preset number of prize balls. Then, within the range of, for example, 1 to 15 prize balls, it is possible to discharge a single unit, an odd number or an even number.

In the prize ball discharge control operation of the apparatus M of the embodiment (mainly during operation), when the first detection means 75 does not receive the ball detection condition (OFF), that is, when the ball detection signal is not inputted, It is considered that a poor ball flow or ball clogging on the prize ball path of the mechanism set board 27 or a poor prize ball penetration failure in the ball path 55 has occurred. On the other hand, as an assumed example, in a state where the first detection means 75 has a detection input based on the ball presence detection condition (ON), the second detection means 76 is set to the no-ball detection means (OFF), that is, the discharged prize ball. When such a count detection signal is not input, it is considered that the ball feeder 70 cannot rotate in response to the transmission of the energizing pulse output corresponding to the detection input of the first detection means 75. As a result,
The first controller C ₁ responds to the occurrence of each of these abnormal situations.
In this case, the emission command being transmitted is immediately interrupted when the respective detection means 75 and 76 are turned off, and in response to this, the pachinko machine P side is notified of the occurrence of an abnormal situation of ball cutting failure due to lamp lighting or the like. On the other hand, the apparatus M itself immediately stops the current control operation based on the stoppage of the power supply to the electric control mechanism 57.

Therefore, when such an abnormal situation (defective ball cutting) is once reset by the manager of the game store and cleared, the normal passage and accommodation of the prize ball into the ball passage 55 causes The first detecting means 75 again detects the presence of a sphere.
(ON) is restored. On the other hand, the ball feeder 70 is allowed to rotate normally and discharges the next one prize ball (prize ball detected by the first detection means 75), whereby the second detection means 76 discharges the prize ball. The prize balls are counted and restored to the count detectable state again. Then, after these restoration processes, the first control device C ₁ re-transmits the energization output in the discharge command based on the safe ball detection condition “Yes” by the safe ball processing device 32 under the reset operation. Will be. On the basis of this, the apparatus M can continuously resume the control operation in accordance with the re-energization pulse output to the electric control mechanism unit 57, discharge the remaining prize balls, and end the operation. It is. As a result, insufficient discharge of the prize ball is avoided.

In each prize ball discharge control operation of the apparatus M of the embodiment, in the safe ball processing device 32, the safe ball detected by the switch 33 is temporarily stopped and held by the stopper 35. Under this condition, at the end of the current control operation,
For example, the stopper 35 is displaced to the ball release position following the instantaneous energizing operation of the electromagnetic solenoid 34 with respect to the input time point of the count expiration detection signal from the second detection means 76, thereby providing a safe The ball is released and discharged as it is. And immediately after this, for example, switch 3
At the time when 3 is in the non-detection state (OFF), the stopper 35 is returned to the original ball stopping position following the recovery of power from the electromagnetic solenoid 34, and the processing state for the next safe ball is restored. Is done. That is, in the device 32, the safe balls are detected and stopped one by one, and the release and discharge processing can be performed in accordance with the timing at the end of the prize ball discharge control operation.

According to this, a suitable power failure countermeasure can be taken. Even if the prize ball discharge device M becomes inoperable once due to a power failure occurring during the pachinko game, appropriate recovery measures against this power failure can be taken. After being maintained in the original energized state, the prize ball discharge device M is detected based on the safe detection and stoppage of the safe ball by the switch 33 and the stopper 35.
There undergoing discharge command from the first control device C _1, is it possible to resume the original discharge control operation from the initial state. For this reason, it is possible to avoid disadvantageous matters for the player, that is, to avoid a shortage of prize balls, and to maintain reliability.

[Modification] The prize ball discharging device in the pachinko gaming machine to which the present invention is applied is not limited to the type and mode of the above-described embodiment, and other examples in which this is appropriately applied and changed are also recommended. You.

That is, as an example, as shown in FIGS. 11 to 13, in the case body 51, the cover plates 5 are provided on both sides of the frame body 52.
2a and 52a are assembled, and two rows of inner and outer ball passages 55 and 55 are defined on the sides thereof. And this case body 51
The electric control mechanism 57 set in the storage chamber 53 of the same type has the same configuration and setting conditions as those described above, and the rotor 67
In the ball feeder 70 closely fitted on the outer periphery, two rows of ball receivers 72, 72 are arranged displaced by a half pitch of the receiver 73 in the circumferential direction. According to FIG. 14 and FIG.
As illustrated in FIG. 12, the horizontal center line XX (see FIG. 12)
With respect to the center of the receiving portion 73 of the ball receiving board 72,
A predetermined number of prize balls can be discharged based on the pulse output under the setting conditions exemplified in FIG. 7 described above, based on the state in which the tips of the claw portions 74 of the other ball receiving board 72 are aligned. .

The relationship between the number of prize balls discharged and the pulse output of the set conditions is illustrated in FIGS. 14 and 15. As can be understood from this, (a) With a fixed number N ₁ (for example, 7), 4 and 3 are set for each column,
P / 2 + P × 3 pulse outputs, (b) In a certain number N ₂ (for example, 10), 5 pulses are set for each column, and P × 5
(C) In the case of (c) a fixed number N ₃ (for example, 15), the number of pulses is set to 8 and 7 for each column, and P / 2 + P × 7 pulse outputs are provided. The balls are alternately ejected one by one.

It should be noted that the entry state of the prize balls in the apparatus M shown in FIGS. 11 to 13 is based on the premise that the apparatus M itself is prepared and controlled to the prize ball discharge reference state. That is, as can be understood from FIG. 12 and FIG. 13, at the time of the initial prize ball entry into the ball passages 55, 55 in each row, the leading prize ball is passed from the decompression guides 56, 56 to the ball feeder 70. It is in a state of being in contact with the receiving portions 73 and the claw portions 74 of the ball receiving boards 72 in the row. Therefore preparation for combining these outermost preceding sphere emission reference position mentioned above, based on the preparation control commands are separately sent from the first control device C _1, with respect to the energization force generating portion 66 of the electric control mechanism unit 57 As a result, a required energizing pulse is output. As a result, the rotor 67 is magnetically released by the canceling action of the electromagnetic force from the generator 66 and the permanent magnetic force from the permanent magnet 61, and the ball feeder 70 receives the pressure of the prize ball under the predetermined pitch. It is rotated by the minute. When the output of the energizing pulse is stopped, the rotor 67 is magnetically stopped only by the permanent magnetic force, and the ball feeder 70 is stopped.
Is stopped, and the leading prize ball of each row is prepared at the illustrated prize ball discharge reference position.

However, the above-mentioned preparation control command is issued at an initial stage before the start of the game under the normal energizing condition of the machine,
The preparation operation is performed only once by the game manager, and for example, a switch, a intentional occurrence of a safe ball (only one ball), or the like may be used.

In each of the devices M, the following changes are also possible. (a) The ball receiving plates 72, 72 of both rows of the ball feeder 70 may be arranged in a uniform manner without any displacement in the circumferential direction, so that an even number of prize balls may be discharged. (b) As for the prize ball detecting means, as shown in the application modification example, under the condition that the first detecting means 75 for confirming the presence of a ball is arranged in the ball paths 55 of each row, one ball path 5
In the case where the detection means 75 is in the non-detection condition (OFF) due to the ball being cut off on the fifth side or the like, based on the detection condition (ON) of the detection means 75 on the other ball passage side, the first Control device C
_In the discharge command from ₁ , the control may be performed such that the electric control mechanism unit 57 is energized to output the pulses of the setting conditions for the number of prize balls to be discharged.

The apparatus of the present invention is not limited to the above-described pachinko game machine, and can exhibit winning combinations based on symbol combinations, regardless of the type of the apparatus including the illustrated embodiment and the application and modification examples. In addition to the prize ball discharge device of the arrangement ball machine, it can be suitably implemented as a ball launching device in a ball rental machine that can use coins and cards, and also as a ball counting and discharging device in a ball processing machine and the like. is there.
