2. Description of the Related Art As is well known in pachinko game machines, when a player hits a ball into the game section one by one with a launcher provided at the bottom of the game board, it collides with an obstacle nail and drops while changing direction at random. A predetermined number of prize balls are given to the player by entering the winning area with a certain probability on the way. Conventionally, such payout of prize balls is generally performed by a mechanical prize ball discharging device as shown in FIG. 1, which is attached to the back surface of the game board and operates by transmitting the physical force generated by the prize balls. It was supposed to be.

That is, in a conventional pachinko machine, a reserve ball storage tank 224 is provided above the back set board 21 attached to the back side of the game board, and the reserve ball is connected to the storage tank 224 to form an S-shaped U-shaped reserve ball. A ball chute 225 is provided to allow the balls to flow down and line up while being turned, a prize ball discharging mechanism section and a prize ball collecting gutter 222 are provided in the center of the back surface of the game board, and simultaneous prize balls are stocked at the bottom to separate them one by one. , A flow controller 260 and an operating lever 265 that is rotated by the weight of the separated winning balls are provided, and the interlocking rod 266 and the link mechanism 2 connected to the end of the operating lever 265 are provided.
67 through the physical force generated by the winning ball,
Prize ball case 268 provided at the end of the ball chute 225
To the damper 269 disposed therebelow, and further to flow down the prize ball discharge path 236 to discharge the prize balls to the front tray. Was doing.

On the other hand, in recent pachinko machines, those having a large-scale variable prize winning device using an electric drive source that creates a state in which a large amount of prize balls are given, which is a so-called lucky seven, have become popular among the players. , Large-scale variable prize winning devices are being installed in most models.

[0005]

With the adoption of such a large-scale variable winning device, the chances of simultaneous or continuous winning balls increasing extremely. However, in the conventional mechanical prize ball discharging mechanism, one discharging cycle takes about 1.5 seconds because the discharging operation is the mechanical link motion as described above, but with the current electric launching device, 100 discharging balls per minute. A batted ball addressed to is shot. That is, since a hit ball is launched into the game board every 0.6 seconds, a large number of prize balls are generated in a short time, the discharge of the prize balls cannot catch up, and the prize balls may accumulate one after another. Therefore, a high-speed prize ball discharging device is desired.

Further, with the speeding up of the prize ball discharging device and the increase in the number of times of discharging as described above, the parts are inoperable due to friction or deformation, or foreign matter is mixed into the prize ball case or the balls are misaligned. It is easy for the discharging operation to be inaccurate and uncertain due to the occurrence of troubles such as the jamming of the discharging function and the stopping of the discharging function or defective discharging. In order to avoid such a problem, it is necessary to have a monitoring function for detecting a ball down abnormality.

However, if the prize ball discharge operation is stopped immediately after detecting an abnormal ball flow, the prize ball may not be discharged even if a prize ball detection signal is generated. If the winning ball is made to flow down before the completion, a trouble may occur between the player and the game shop depending on whether or not the winning ball has been generated.

[0008]

The present invention has been made in view of the above-mentioned problems, and the player is guided to the rear surface of the game board by winning the prize area provided on the front surface of the game board. A collecting gutter that collects the winning balls at a predetermined location, a stocking ball that is arranged at the lower end of the collecting gutter and temporarily stocks the winning balls, and a winning ball separating device that can separate the winning balls to one, In a pachinko machine equipped with a prize ball discharging device capable of discharging a prize ball, the prize ball discharging device is activated based on detection of the prize ball in the prize ball separating device to start discharging a predetermined number of prize balls. In addition, the prize winning ball separating device is operated after one discharge operation of the prize ball discharging device is completed, and one stocked prize winning ball is separated and flowed down.

[0009]

According to the above-described means, the winning ball is flown down after the discharge of the prize ball is finished. Therefore, even when the discharge operation of the prize ball is stopped due to the detection of an abnormal flow of the ball, the prize ball is generated. It is possible to prevent a trouble from occurring between the player and the game store over whether or not the game has been performed.

It is positioned so as to have a space for one sphere from the ends of 1, 25c2, and a discharge gutter 44 connected to the upper end of the saucer storage part 36 is provided below it and hits the claw part 42b. The prize ball B that has come into contact is locked so as not to flow out, and the recess 42
The prize ball B ′ engaged with a comes into contact with the blocking plate 43 and is sandwiched between the prize ball B ″ and the succeeding prize ball B ″, and when the sprocket 42 rotates, the prize ball B ′ is separated by the claw portion 42b, and the prize gutter 44 is provided below. It is designed to be run down.

FIGS. 10 and 11 show the discharging action of the prize ball discharging device 40. As shown in FIG. 10, the ball B1 engaged with the recess 42a1 of the sprocket 42 is the claw 42b1 associated with the rotation of the sprocket. When the sphere B3 following the sphere B1 comes into contact with the claw portion 42b1 as shown in FIG. 11, the sphere B2 engages with the recess 42a3 and is downwardly moved by the claw portion 42b2. It is sent out and separated. Then, when the sphere B4 subsequent to the sphere B2 comes into contact with the claw portion 42b2, the sphere B3 is depressed into the concave portion 4b.
2a2 is engaged and separated by the claw portion 42b2. In this way, the prize balls aligned in the outlets 25c1 and 25c2 are alternately taken out one by one and discharged to the discharge gutter 44 by the separating action accompanying the rotation of the sprocket 42.

Further, an L-shaped cutout is formed in the blocking plate 43, and this cutout is formed as shown in FIG.
Discharge ball detector 4 including a plurality of sensors 45a to 45d
5 are provided. Among the sensors 45a to 45d, 45a and 45b detect whether or not there is a ball to be ejected next in the outlet portions 25c1 and 25c2, and the sensors 45c and 45d confirm whether or not the ball is ejected. Any of them can be configured using an optical sensor or a proximity switch. The prize ball discharging device 40 starts driving the motor 41 based on the detection signal from the prize ball detector 55 in the prize ball separator 60, and counts the signal output from the discharge ball detector 45. Then, the motor 41 is stopped by the discharge end signal output when the predetermined number is reached, and one discharge operation is completed.

The winning separator 60 is constructed, for example, as shown in FIG. That is, the winning ball discharge passage 22 is bent laterally at the entrance to form an opening 22a, and a movable piece 61 is rotatably provided below the opening 22a. A micro switch 55 for winning ball detection is arranged below the movable piece 61, and a separation operating rod 63 rotatably attached by a pin 62 is provided below the micro switch 55. The tip of the separating operating rod 63 is bent upward, and a bending piece 63a is formed which can project into the winning ball discharge passage 22 from the opening of the tip of the movable piece 61. A blocking piece 63b is formed at a position separated by one.

The separating operating rod 63 is rotated by a solenoid 64 arranged below the separating operating rod 63 to separate the winning balls one by one. That is, before the winning ball enters the discharge path 22, the separation actuating rod 63 is rotated upward and the bent piece 63 a at the tip is projected into the discharge path 22. Therefore, in the normal state where the solenoid 64 is demagnetized, the winning balls, which are the same or continuous, come into contact with the bent pieces 63a and stop and are aligned in a line as shown in FIG. 61 is rotated downward and the micro switch 55 is turned on. Also,
When the solenoid 64 is energized, the separation actuating rod 63 is rotated downward, and the winning ball at the top is discharged to the discharge gutter 22 as shown in FIG.
It is made to flow into the inside, and the following winning ball is the blocking piece 6
Flowing is blocked by 3b. And solenoid 6
When the electricity to 4 is cut off, the separation operating rod 63 is rotated upward by the repulsive force of the spring 64a. Then,
The blocking piece 63a is disengaged and the next winning ball moves to the movable piece 61, and the winning ball detector (micro switch) 55
Turn on. As described above, the winning ball separator 60 is configured to separate the winning balls one by one and output a detection signal for each winning ball.

FIG. 14 is a block diagram showing an example of an electrical control system of the prize ball discharging device 40 and the prize ball separating device 60 by the control device 50. A winning detection signal (pulse) generated from the winning ball detector (micro switch) 55 corresponding to each winning ball is supplied to the signal forming circuit 51. A drive signal is formed based on the winning detection signal and is supplied to the motor 41 in the prize ball discharging device 40 to start discharging. At this time, taxiway 2
If there is no spare ball in 5, the drive signal is not formed even if the winning detection signal is input, and the motor 41 and the winning ball separator 6
It is possible that the solenoid 64 in 0 is not driven. On the other hand, when the motor 41 is driven and the discharge is started, a pulse signal is output from the discharge ball detector 45 for each discharge ball and is supplied to the counter 52 for counting. The count value of the counter 52 is supplied to the comparison circuit 54 together with the set value in the setter 53 for comparison. The number of prize balls to be paid out for one winning ball is set in the setter 53, and when the count value of the counter 52 matches the set value, the comparison circuit 54 outputs a discharge end signal. . This end signal stops the motor 41 of the prize ball discharging device 40, energizes the solenoid 64 in the prize ball separator 60, rotates the separation actuating rod 63, and separates and drops one prize ball. . And separation of prize balls,
When the winning ball detector 55 is turned off by flowing down, the solenoid 64 is demagnetized, the separation operating rod 63 is returned, and the next winning ball is taken in and detected by the winning ball detector 55.

That is, the prize ball separating device 60 detects the prize balls, and the prize ball discharging device 40 starts the discharging operation. When the number of discharged balls reaches a predetermined number, the prize ball discharging device 40 finishes discharging the prize ball separator 60. At, the winning balls are separated and detected, and the above operation is repeated again to discharge the prize balls according to the number of winning balls. Further, the signal forming circuit 51 monitors a ball down abnormality based on a signal from a downflow abnormality detector 57 provided in the middle of the guide path 25, and when an abnormality signal comes in, a winning detection signal is output. The prize ball discharging device 40 is not operated even if it enters. The downflow abnormality detector 5
7 are provided for each row of spare balls which are arranged in two rows in the guide path 25 and flow down.

During the discharge, the guideway 25 is caused by a cause such as a ball jam.
When it is detected by the discharge ball detector 45 that no balls are discharged to the outlets 25c1 and 25c2 at the end of the control unit 50, the controller 50 immediately receives the output and receives the output.
When the prize balls enter the outlets 25c1 and 25c2, the motor 41 is operated again to discharge the remaining prize balls. When one discharge is completed, the control device 50 sends a signal to the winning ball separator 60 to separate one winning ball stored and let it flow down. The controller 50 is made to input the signal from the ball shortage detector 56 so that the preliminary storage unit 2
It is also possible to stop the driving of the motor 41 and stop the discharge of the prize balls when the spare balls are not present in 4 and the detection signal is sent to the control device 50. Also in this case,
It is preferable that the control device 50 stop the next discharge after the discharge operation of the current time is completed, that is, after the discharge of a predetermined number of prize balls for one winning ball is completed.

In the above case, the game is continued even if the discharge of the prize balls is stopped, the generated prize balls are stored in the prize ball separator 60, and the reserve balls are supplied to the reserve reservoir 24. At this time, it is preferable to start the discharge of the prize balls again by the control signal from the control device 50. On the other hand, the control device 50
When the abnormal signal comes in while monitoring the abnormal flow-down of the sphere based on the signal from the downstream flow abnormality detector 57 provided in the middle of the guide path 25 where dust or foreign matter is likely to enter and cause a ball jam. The prize ball discharging device 40 is stopped.

In the above embodiment, by changing the set value of the setter 53, an arbitrary number of prize balls can be paid out per one time. In addition, a plurality of setting devices 53 of the above-described embodiment are provided to make the set values different, and a prize detector is provided for each of the winning regions 15 to 18 to detect the type of winning and detect the type of winning. It is also possible to change the number of prize balls discharged. Further, as in the embodiment, instead of the prize ball discharging device 40 configured to drive the separating sprocket 42 by the motor 41 to discharge the prize balls, the prizes are separated one by one using a solenoid and a downflow prevention member. It is also possible to use a device that is configured to eject a sphere.

In the provided pachinko machine, the prize ball discharging device is activated based on the detection of the prize ball in the prize ball separating device to start discharging a predetermined number of prize balls,
After the end of one discharging operation in the prize ball discharging device, the prize winning ball separating device is operated so that one of the stored prize balls is separated and allowed to flow down. Therefore, even if the ball discharge abnormality is detected and the prize ball discharge operation is stopped, the player and the amusement store will go over whether or not a prize ball has been generated. It is possible to avoid the occurrence of trouble.

Further, in the present invention, since the winning balls are individually detected and electronically processed, even if a plurality of winning balls are simultaneously generated, the discharge of the prize balls due to the ball clogging is stopped. In addition to the disappearance, accurate payout is performed, and when the flow of spare balls or prize balls is monitored and a shortage of spare balls or an abnormality such as a ball jam due to the inclusion of foreign matter is detected, the specified number of balls are discharged. Since the operation related to the discharge of the prize ball is stopped after the operation,
Since empty discharge and halfway prize ball discharge are prevented, an unfair result is not given to the player, and it is not stopped in the middle of one discharge operation, so it is between the player and the game store. It is possible to prevent troubles from occurring in advance.
