The present invention relates to a ball cutting control device that ejects a predetermined number of pachinko balls (prize balls) in response to each ball ejection command for detection.

(Prior art) Figures 5 and 6 show a first comparative example of a ball cutting device for a conventional pachinko machine, in which pedestals 1 and 1' are arranged annularly at a constant pitch, and sprockets 2 and 2' are shifted by half a pitch. and fix it to the rotating shaft 4' of the motor 3, and turn on the motor 3 when the ball enters the hole (not shown).
Sprockets 2, 2' are rotated to alternately discharge balls 4 from both sprockets 2, 2' to a discharge path 5, which is counted by a sensor 6, and when a predetermined number is reached, the motor 3 is stopped.

FIG. 7 shows a second conventional comparative example, in which a solenoid 12 is placed at the tip of the discharge path 11 of the balls 10, and a plurality of partition solenoids 13, 14, 1 are placed at a predetermined number of balls in the middle position.
5 and 16, the outlet solenoid 12 is turned on, the outlet 11 is closed by the stopper 12', and the balls 10 are stored in the outlet path 11. When a ball enters the hole (not shown), the partition solenoid 13 corresponding to the number of balls to be ejected is operated to partition the balls 10 with the stopper 13', and then the ejection solenoid 12 is turned on and the stopper 12' is retracted. A discharge port 11' is opened to discharge a predetermined number of balls.

FIG. 8 shows a third conventional comparative example, in which a partition arm 23 that swings around a fulcrum 22 is pivotally attached to the side of the discharge path 21 of the ball 20, and the tip of the arm 23 is bent to form a stopper 24. A stopper 25 is removably attached to the rear part, and the attachment position is variable depending on the number of balls to be dispensed.The arm 23 is constantly rotated in the direction of arrow A by a spring 26, and the stopper 24 is attached to the discharge port 2.
1' is closed, and the stopper 25 is retracted from the discharge passage 21. Therefore, the balls 20 are accumulated in the discharge path 21 up to a point above the stopper 25. When a ball enters the hole (not shown), the solenoid 27 is turned on, the arm 23 is rotated in the direction of arrow B, the solenoid 25 partitions off the ball 20 in the discharge path 21, and at the same time the stopper 24 is retracted. Outlet 2
1' is opened and a predetermined number of balls are discharged.

(Problems to be Solved by the Invention) In the above-mentioned prior art, in the first comparative example, the cumulative error in the stop position due to the rotational inertia of the motor causes a discrepancy in the number of balls dispensed, and since the motor is used, it is small. There was a problem that it could not be converted into
Furthermore, in the second and third comparative examples, in order to change the number of balls out, it was necessary to change the position of the stopper or increase the number of solenoids, which caused the problem that the structure was complicated, large and expensive.

(Purpose) The present invention was proposed to solve the above-mentioned problems, and in response to each ball launch command,
A ball sending member, which is rotatably stopped by a magnetic force switching rotation control unit, is rotated while receiving each pachinko ball in the delivery path to continuously cut balls, and a predetermined number of ejected pachinko balls are ejected. At the end of the count detection, the magnetic force switching rotation control unit is immediately stopped, and the ball feeding member is stopped and held to complete the ball cutting operation for the current round. It is an object of the present invention to provide a ball cutting control device that is compact and easy to control, and can easily change the number of pachinko balls to be ejected using the device itself.

A ball cutting control device that continuously discharges a predetermined number of pachinko balls one by one, includes a stator made of a magnetic material and having a large number of protrusions for concentrating magnetic force on the outer periphery. A rotor made of a magnetic material is rotatably fitted and supported on the outer periphery of the stator and has a large number of protrusions for concentrating magnetic force on the inner periphery, and a rotor is installed between the stator and the rotor to constantly direct magnetic force in a fixed direction. a permanent magnet that is actuated to attract and hold the rotor through the protrusion, and a conductive electromagnetic force generator that generates magnetic force in a energized state corresponding to the ball ejection command and acts in a direction to offset the magnetic force of the permanent magnet. and a sprocket-like ball feeder that is integrated into the outer periphery of the rotor and is capable of pitch rotation while receiving pachinko balls in the delivery gutter part one by one in a ball receiving part, and a pachinko ball ejected by this ball feeder. and a counting detection sensor configured to count and detect the balls one by one and cut off the energization to the electromagnetic force generating section at the end of the count detection for a predetermined number of balls, and the counting detection sensor is configured to cut off the current to the electromagnetic force generating section when the counting of a predetermined number of balls is completed, Under the condition that the energizing electromagnetic force generating section is not energized, the rotor is attracted and stopped by the magnetic force of the permanent magnet to hold the ball feeder unrotatable, and when a ball ejecting command is generated, the corresponding energizing electromagnetic force generating section is energized. Under these conditions, the magnetic force generated from the same generator and the magnetic force of the permanent magnet cancel each other out to release the rotor from its adsorption stop and continue ejecting pachinko balls by rotating the ball feeder, and the counting detection sensor 1. A ball cutting control device for a pachinko game machine, characterized in that the ball cutting operation for the current round is set to end when the electromagnetic force generating section is de-energized at the time of completion of count detection.

(Example) Hereinafter, a detailed explanation will be given based on the illustrated example. 1 to 3 show a first embodiment. A stator 31 made of a magnetic material is provided with a large number of protrusions 31a, 3a' for concentrating magnetic force on its outer circumference, and a stator 31 is rotatably fitted and supported on the outer circumference of the stator 31 and has a large number of protrusions for concentrating magnetic force on its inner circumference. A rotor 34 made of a magnetic material in which portions 34a and 34a' are formed and arranged in a spline shape, and a rotor 34 that is incorporated between the stator 31 and the rotor 34 so that a magnetic force is constantly applied in a fixed direction to the protrusions 31a and 31
Permanent magnet 32 that can attract and hold the rotor 34 via a', 34a, 34a' and energization that generates magnetic force in the energized state corresponding to the ball ejecting command and acts in a direction that cancels out the magnetic force of the permanent magnet 32. A sprocket-shaped ball feeding machine is integrated with the magnetic force generating part 33 and the outer periphery of the rotor 34 and is capable of pitch rotation while receiving pachinko balls in the sending gutter part 38 one by one with ball receiving parts 37a and 37a'. 37, a counting device configured to count and detect the pachinko balls ejected by the ball feeder 37 one by one and cut off the electricity to the electromagnetic force generating section 33 when the counting of a predetermined number of balls is completed. Detection sensor 41
In a non-energizing condition to the electromagnetic force generating section 33 before the ball release command is generated, the rotor 34 is attracted and stopped by the magnetic force of the permanent magnet 32, and the ball feeder 37 is held unrotatable. death,
Electromagnetic force generating section 33 that responds when a ball ejection command is generated
Under the energization conditions, the magnetic force generated from the generating unit 33 and the magnetic force of the permanent magnet 32 cancel each other out, and the rotor 34 is released from its adsorption stop, and the ball feeder 37 continues to eject the pachinko balls by rotating the ball feeder 37. It is set so that the ball cutting operation for the current round ends when the counting detection sensor 41 completes the counting and the electromagnetic force generating section 33 is not energized.

The ball feeder 37 has the same number of ball receivers 37a, 37a' formed on its outer periphery in each annular row unit, and is displaced from each other by half a pitch in the rotational direction, so that the ball receivers 37a, 37a' in each row are displaced from each other by half a pitch in the rotational direction. 37a' is set so as to face into each row of passages 38a in the sending gutter section 38 so as to be able to receive pachinko balls one by one.

Next, the effect will be explained. When the ball does not enter the hole (not shown) of the pachinko machine, the electromagnetic force generating section 33 is not energized, and the rotor 34 and stator 31 are not energized.
A closed magnetic path is formed, and the protrusions 34a of the rotor 34,
34a' are protrusions 31a, 31 of the opposing stator 31;
The rotor 34 is stopped because it is attracted by a'. When the ball enters the hole, the electromagnetic force generating section 33 is energized to generate a magnetic flux in a direction that cancels the magnetic flux of the closed magnetic path, and the rotor 34 moves the ball 4 placed on the ball receiving sections 37a, 37a'.
The ball rotates with a weight of 0, and falls alternately from both ball receiving portions 37a and 37a' every 34 half-pitch rotations into the discharge path 39. The number of falling balls is counted by the sensor 41, and when the number reaches a predetermined value, the power to the conducting electromagnetic force generating section 33 is turned off, the magnetic flux by the conducting electromagnetic force generating section 33 disappears, and the protrusions 34a, 34a' of the rotor 34 are instantaneously turned off. The protrusions 31a, 31 of the stator 31 are closed by the magnetic flux of the porcelain.
It is attracted by a′ and stops.

FIG. 4 shows a second embodiment, where 50 is a stator, 51 is a rotor, and an electromagnetic force generating section 52 is passed through the rotor 51.
are arranged. The operation is the same as in the first embodiment.

Depending on the operating conditions of the device itself, the ball release command is issued by a detection signal for each safe ball in a pachinko machine, and by a ball lending operation signal after inserting a coin or card in a ball lending machine.

Before the ball launch command, the electromagnetic force generating section 33 attracts and holds the rotor 34 under a non-energizing condition, that is, using the magnetic force of the permanent magnet 32.

At the time of a ball launch command, the rotor 34 is released from adsorption due to the energization condition of the electromagnetic force generating section 33 and the countervailing action of both magnetic forces.

At the end of counting detection, the energizing electromagnetic force generating section 33 is returned to the non-energizing condition.

(Effects) According to the present invention, the number of pachinko balls ejected can be easily changed by simply changing the counting detection expiration conditions of the counting detection sensor 41, and the magnetic force having the permanent magnet 32 and the electromagnetic force generating section 33 can be easily changed. Adopts a switching rotation control unit and does not use a motor, making it inexpensive and compact. In addition, since the electromagnetic force generator 33 is only energized and energized, control management becomes easy, and it is possible to prevent the rotor 34 and the ball feeder 37 from being rotated by ball pressure during a power outage.
