BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize ball payout device for a ball game machine, which detects a ball breakage of a prize ball at a portion as close as possible to a payout portion of a prize ball payout means, and cuts out a ball during a payout operation. When is detected, the payout unit is stopped after the required number of prize balls have been paid out.

[0002]

2. Description of the Related Art In a ball game machine such as a pachinko machine, when a hit ball enters a winning area of a game board, a preset number of prize balls are paid out by a prize ball payout device and returned to a player as a winning profit. To do. This prize ball payout device conventionally supplies prize balls from the prize ball tank to the prize ball supply passage of the prize ball payout means,
The prize balls in the prize ball supply passage are paid out by the payout unit through the prize ball payout passage in a required number. Then, a ball break switch is provided on the bottom of the prize ball tank or on the prize ball tank rail between the prize ball tank and the prize ball supply passage, and when this ball break switch detects that the prize ball has run out, the ball is hit in the winning area. Even if the player enters, the payout of the prize balls is stopped until the prize balls are supplied.

Further, in a ball game machine such as a pachinko machine, a photo sensor is used as a ball loss detecting means for detecting a ball loss of a prize ball or the like in a passage, and a sensing arm pushed up by the prize ball or the like in the passage is vertically rocked. There is one that is rotatably supported and turns on the photosensor when the sensing arm moves up, shuts off the light when the sensing arm goes down, and turns off the photosensor to detect a ball out in the passage.

[0004]

In the conventional prize-ball payout device of this type, since the ball-out switch is located far away from the payout portion of the prize-ball payout means, the prize-ball payout is performed from the lower side of the ball-out switch. There is a problem when the prize balls are blocked up to the prize ball supply passage of the means. That is, in this case, even though the inside of the prize ball supply passage is in the out-of-ball state, the out-of-ball switch does not work, so that the payout unit continues the payout operation and an empty payout state occurs.

On the other hand, if the ball burnout switch is provided in the immediate vicinity of the dispensing portion, the problem of empty dispensing can be prevented, but even during the dispensing operation, the dispensing operation must be interrupted immediately if the ball burnout switch operates. The problem remains that the required number of prize balls cannot be paid out to the end.

Further, the conventional ball breakage detecting means operates the photo sensor by the sensing arm, but since the photo sensor is used, there is a problem that malfunction occurs due to static electricity generated by friction of the game ball. That is, steel balls are used for the game balls, and static electricity is generated by mutual friction, and the game balls are charged. Then, when the electric charge is discharged, a spark is generated, which may cause the photo sensor to malfunction.

In view of the above conventional problems, the present invention detects the shortage of a prize ball as close as possible to the payout portion of the prize ball payout means to prevent an empty payout operation due to clogging of the prize ball and the payout. It is an object of the present invention to ensure that all required number of prize balls can be paid out even if the balls run out during the payout operation of the unit, and further to prevent malfunction due to static electricity so that the prize balls can operate reliably.

[0008]

The present invention provides a prize ball tank 27.
The prize balls A are supplied from the prize balls to the prize ball supply passage 34 of the prize ball payout means 33, and the prize balls A in the prize ball supply passage 34 are paid out by the payout unit 36 through the prize ball payout passages 35 in the required number. In the prize ball payout device of the ball game machine, the prize ball supply passage 34
The sensing arm 91 pushed up by the prize ball A in the inside is separated from the payout part 36 so that the prize balls A for at least one payout remain in the prize ball supply passage 34 between the payout part 36 and the prize arm A. A magnetic body 92 is provided that is pivotally supported so that it can swing up and down, a magnetic body 92 is provided on the free end side of the sensing arm 91, and when the sensing arm 91 descends, the magnetic body 92 activates to detect the ball severing. A control means (10) provided with a confirmation switch (39), and when the out-of-ball confirmation switch (39) detects out-of-ball during the dispensing operation of the dispensing unit (36), stops the dispensing unit (36) after the completion of the dispensing operation
3 is provided.

[0009]

When the prize ball A supplied from the prize ball tank 27 to the prize ball supply passage 34 of the prize ball dispensing means 33 is cut off, the sensing arm 91 descends. At this time, the magnetic body 92 descends integrally with the sensing arm 91, and the magnetically sensitive ball break confirmation switch 39 operates to detect the ball break, so that the control means 103 causes the payout part 36 of the prize ball payout means 33. To stop the payout operation.

Even if the out-of-ball confirmation switch 39 detects the out-of-ball, the prize-ball supply passage 34 between the payout unit 36 and the sensing arm 91.
, The prize balls A for at least one payout remain. Therefore, if the out-of-ball check switch 39 detects the out-of-ball during the payout operation of the payout unit 36, the payout unit 36 is stopped after the end of the payout operation, and all the required number of prize balls are paid out with certainty.

When a large number of winning balls continuously enter the winning area, the winning balls are collected from the winning ball outlets 44 to 47 of the game board 5 into the winning ball tank 43, and the winning ball tank rail 48 below it. The coins are sequentially stored in the winning ball tank 43 from the side. Then, the winning ball is sent to the winning ball dropping means 49 via the winning ball tank rail 48, and whenever the winning ball detecting switch 52 detects the winning ball, the ball dropping solenoid 51 is excited to operate the ball dropping arm 50. , Each winning ball is dropped one by one.

On the other hand, when the winning ball detecting switch 52 detects the winning ball, the payout command signal S ₃ is inputted to the control means 102,
The payout motor 37 of the prize ball payout means 33 rotates by a predetermined angle, and the rotating body 36 fixed to the output shaft 67 thereof is rotated in the direction of arrow b in FIG.

Then, the prize balls A supplied from the prize ball tank 27 through the prize ball tank rail 28 to the prize ball supply passage 34 of the prize ball dispensing means 33 and stocked are paid out by a required number by the rotation of the rotating body 36. Pay out. The prize balls paid out by the rotation of the rotating body 36 fall from the prize ball payout passage 35,
It is supplied to the upper plate 11 via the prize ball guide passage 38. Hereinafter, every time the winning ball detecting switch 52 detects a winning ball, the payout motor 37 of the winning ball payout means 33 is actuated to rotate the rotating body 36 to sequentially pay out the winning balls A.

In a normal state, the prize ball tank 27, the prize ball tank rail 28, and the prize ball supply passage 34 are filled with the prize ball A, and both the ball break switch 29 and the ball break confirmation switch 39 are turned on. is there. When the prize ball A is full in the prize ball supply passage 34, as shown in FIG.
It is pushed up by and is rotated upward around the shaft 109,
Since the magnet 92 is close to the side of the out-of-ball confirmation switch 39,
The out-of-ball confirmation switch 39 is in the ON state.

When the prize ball tank rail 28 or the prize ball A in the prize ball supply passage 34 is out of the ball due to a failure of the prize ball supply system, a ball clogging, etc., the ball out switch 29, the ball out confirmation switch
39 turns off. When the prize ball A in the prize ball supply passage 34 is broken, as shown in FIG. 10, the sensing arm 91 pivots downward around the shaft portion 109 and descends, and the magnet 92 causes the ball break confirmation switch 39.
Since the player is moving away from this, the out-of-ball confirmation switch 39 is turned off to detect the out-of-ball state. In this case, the magnet 92 is the sensing arm.
Since it is on the free end side of 91, the sensing arm 91
Smoothly descends, and when it descends, the stopper 115 engages with the guide wall 90a.

Ball out switch 29 and ball out confirmation switch
When both 39 are turned off, the out-of-ball discrimination means 100 outputs the out-of-ball signal S ₁ . At that time, if the payout command signal S ₃ is not present, the control means 103 disables the payout motor 37 as it is, and if the payout command signal S ₃ is already present and the payout operation is in progress, the payout motor 37 is operated after the end of the operation. Disable rotation.

When a ball clogging occurs on the side of the prize ball tank rail 28, the prize ball A in the prize ball supply passage 34 decreases due to the payout, and the ball break switch 29 is in the ON state, but the ball break confirmation switch Since 39 is turned off, the ball clogging determination means 101 outputs the ball clogging signal S ₂ . Even at this time, a payout command signal S ₃ is intact unrotatable payout motor 37, also already if during payout operation. However payout command signal S _3, so as not to rotate the payout motor 37 after the end of the operation To do.

When the prize ball A is paid out by the rotating body 36,
The payout detection switch 40 is turned on / off. However, if the payout command signal S ₃ is present and the out-of-ball confirmation switch 39 is on, but the payout detection switch 40 is not turned on / off at all, the ball is clogged in the rotating body 36 of the payout chamber 57. Therefore, the payout abnormality determining means 102 outputs the payout abnormality signal S ₄ , and the control means 103 immediately stops the payout motor 37. In addition, when the payout motor 37 is made unrotatable or forcibly stopped, the entire game function may be stopped.

According to the structure of this embodiment, the sensing arm 91 for actuating the out-of-ball confirmation switch 39 has the upper end portion of the prize ball supply passage 34 of the prize ball payout means 33, that is, the rotating body for paying out the prize ball A. Since it is located as close as possible to 36, even if the ball is clogged on the prize ball tank 27 side, the rotating body 36 does not idle and the idle payout operation is not continued.

In the prize ball supply passage 34 between the sensing arm 91 and the rotating body 36, there are prize balls A more than the number of prize balls to be paid out in at least one payout operation, and the balls are out during the payout operation. If the problem occurs, the payout motor 37 and the rotating body 36 are stopped after the end of the operation, so that the required number of prize balls A can be surely paid out even when the ball is out.

Further, the out-of-ball confirmation switch 39 is made magnetically sensitive, and the out-of-ball confirmation switch 39 is set by the magnet 92 of the sensing arm 91.
Since it is operated, even if the prize ball A side is charged with static electricity and discharged, the ball break confirmation switch 39
Does not malfunction. Moreover, since the sensing arm 91 has the magnet 92 on the free end side, when the prize ball A is lost in the prize ball supply passage 34, the weight of the magnet 92 causes the sensing arm 91 to quickly descend around the shaft portion 109. Therefore, even if there is some frictional resistance on the shaft portion 109 or the like, or dust or the like is caught, the sensing arm 91 can be smoothly and reliably moved up and down.

In the embodiment, the rotating body 36 is illustrated as the payout portion of the prize ball payout means 33, but the present invention is not limited to this. Also, in the embodiment, the sensing arm 91 has a magnet.
Although 92 is provided, if a magnet is provided on the side of the out-of-ball confirmation switch 39, the sensing arm 91 may be provided with a non-magnetized magnetic plate. Therefore, it is not necessary to attach a magnet to the sensing arm 91.
It is not necessary to provide 92. Further, the present invention can be similarly implemented in a ball game machine other than a pachinko machine.

[0049]

According to the present invention, the sensing arm 91 pushed up by the prize ball A in the prize ball supply passage 34 is moved to the payout portion 36.
The prize balls A for at least one payout are left in the prize ball supply passage 34 between and, and the prize balls A are pivotally supported separately from the payout portion 36 so as to be vertically swingable. A magnetic body 92 is provided on the side, and when the sensing arm 91 descends, a magnetic sensitive type out-of-ball confirmation switch 39 that is operated by the magnetic body 92 to detect the ball out is provided. When the confirmation switch 39 detects that the ball has run out, the control means 103 for stopping the payout part 36 after the payout operation is completed is provided, so that the award ball A runs out as much as possible.
Can be detected in the vicinity of the payout unit 36, and the empty payout operation due to clogging of the prize balls A can be prevented, and even if the balls run out during the payout operation of the payout unit 36, all the required number of prize balls A are surely secured. Can be paid out.

Further, in the present invention, since the magnetic sensitive type ball break confirmation switch 39 is used and is operated by the magnetic body 92 to detect the ball break, it becomes a prize ball like a conventional photo sensor. The ball discharge confirmation switch 39 does not malfunction due to the generated static electricity discharge. Moreover, since the magnetic body 92 is on the free end side of the sensing arm 91, when the prize ball A is lost in the prize ball supply passage 34, the sensing arm 91 quickly descends due to the weight of the magnetic body 92. Therefore, even if there is some frictional resistance due to manufacturing error or the like, or dust or the like is caught, the sensing arm 91 can be smoothly and reliably moved up and down.
