Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a winning ball receiving device for a pachinko machine. The present invention relates to a winning ball receiving device which is configured to reliably close after being heated.

[Conventional technology]

Pachinko machines are equipped with various winning devices to make the game more interesting. In the winning ball device called Atatsuka, which has a door plate that can be opened and closed, when a pachinko ball wins in a specific safe hole, the symbol combination of a slot machine attached to a pachinko machine, for example, is ``7-7''. -7'', the door plate opens. Since this door plate opens so as to protrude from the board surface, pachinko balls flowing down the board surface are guided to the winning ball receiving part by this door plate, making it very easy to win a prize.
The door plate opened in this manner is closed when a certain number of pachinko balls have been won through the door plate.

In order to open and close the door plate in this manner, an opening/closing device using a motor has been proposed. That is,
An interlocking mechanism such as a lever or a cam is provided between the motor and the door plate, and the door plate is opened and closed by driving this interlocking mechanism with the motor. According to this,
Since the motor can remain stopped when the door plate is held in either the closed or open position, there is an advantage that power consumption can be saved compared to using a solenoid.

[Problem that the invention attempts to solve]

By the way, when using the door plate as described above,
In the process of moving the door plate to the closed position, a pachinko ball may get caught between the upper edge of the door plate and the lower edge of the opening that should be covered by the door plate. If such a situation occurs, the door plate will no longer be able to rotate, but the drive current for closing the door plate will continue to be supplied to the motor, significantly shortening the life of the motor. In order to avoid such problems, if the drive current is supplied to the motor for a certain period of time, the drive current to the motor will be cut off before the door plate is securely held in the closed position. A weight is attached to the door plate to rotate it to the open position, so if the motor stops before the door plate is held in the closed position as described above, the door plate will open again. becomes.

The present invention was developed to solve the above-mentioned drawbacks of the conventional technology. To provide a winning ball receiving device for a Pachinko machine which prevents a door plate from remaining open even if the drive of a motor is stopped before the balls are held.

[Means for solving problems]

In order to achieve the above object, the present invention drives a motor to move the door plate to a closed position when a certain number of balls have won through the open door plate, and the door plate is moved to the closed position. After the motor is driven to move the door plate to the closed position, when it is further detected that a winning has occurred through the door plate, the motor is driven again to move the door plate to the closed position. This is what I did.

An embodiment of the present invention will be described below with reference to the drawings.

〔Example〕

The first part shows the outline of the Atatsuka device using the present invention.
In the figure, a mounting plate 2 in which a horizontally long opening 1, which serves as an entrance for winning balls, is formed is fixed to the game board 3 so as to be substantially flush with it (see FIG. 3).
A door plate 5 is rotatably attached to the mounting plate 2 by shafts 4, 4 so as to open and close the opening 1. There are weights 6, 6 on both sides of the front of this door plate 5.
are integrally attached, so that the door plate 5 is always biased in the opening direction.

Pachinko balls entering through the opening 1 reach a receiving chamber 8 formed at the rear of the opening 1, and then are discharged from an exit 9. On the back side of reception room 8,
A detection lever 10 is pivotably mounted so as to face the exit 9, so that the detection lever 10 is swung by a pachinko ball passing through the exit 9. This swinging of the detection lever 10 is detected by the microswitch 12 as an electrical signal.

An engagement lever 14 is integrated with one side edge of the door plate 5. This engagement lever 14 passes through a slot (not shown) formed in the mounting plate 2 and projects to the back side of the mounting plate 2. An opening/closing lever 16 that is pivoted to a support plate 15 engages with the engagement lever 14, and an arm 18 that is rotated by a motor 17 is in sliding contact with the upper surface of the opening/closing lever 16.

In FIG. 2, when the arm 18 is in the position shown by the solid line, the opening/closing lever 16 is prevented from rotating upward, so the door plate 5 is prevented from rotating counterclockwise by the weight 6. ing. When the motor 17 rotates forward from this state and the arm 18 moves to the position shown by the two-dot chain line, the opening/closing lever 16 becomes able to rotate upward, so that the door plate 5 also moves to the position shown by the two-dot chain line. That is, it becomes possible to rotate to the open position. Further, when the motor 17 reverses, the arm 18 moves from the position shown by the two-dot chain line to the position shown by the solid line, and the door plate 5, which was in the open position, returns to the closed position.

Note that when opening and closing the door plate 5 as described above, the motors 17 are each driven for a certain period of time. When the arm 18 comes into contact with the support plate 15 or when the opening/closing lever 16
When it comes into contact with the stopper 16a formed protruding from the upper surface, the extra rotation of the motor 17 is absorbed by the slip mechanism 19 provided between the arm 18 and the drive shaft 17a of the motor 17. It's becoming like that.

The driving of the motor 17 is controlled by a control circuit shown in FIG. In FIG. 4, for example, when a slot machine attached to a pachinko machine is operated and the symbols become a combination of "7-7-7", a pulse signal is output from the Yakumono winning determination section 22. The timer 23 is activated by this pulse signal, and a signal is supplied to the input terminal a of the motor drive circuit 24 to cause the motor 17 to rotate forward for a certain period of time. As a result, the arm 18 is moved to the position indicated by the two-dot chain line in FIG. 2, so that the door plate 5 is opened. Note that, at this point, the driving of the motor 17 has been stopped.

The pulse signal from the Yakumono prize determining section is also input to the changeover switch 25. This results in
The contact piece 25a can now be switched from terminal X to terminal Y. A micro switch 12 provided facing the exit 9 outputs a ball detection signal every time a pachinko ball passes the exit 9, and this signal is counted by a counter 26.

In this way, the number of pachinko balls won through the door plate 5 is counted by the counter 26, and when the number reaches 10, the counter 26 outputs a 10 count signal. This 10 count signal is the timer 27
is started, and the input terminal b of the motor drive circuit 24 is
A signal is supplied to reverse the motor 17 for a certain period of time. As a result, the arm 18 becomes 2 in FIG.
Transition from the dotted chain line position to the solid line position, and open/close lever 1
The door plate 5 is closed via the door plate 6. Further, the 10 count signal outputted from the counter 26 resets the count value of the counter 26 and is also supplied to the changeover switch 25. As a result, the contact piece 25a is switched to the terminal X, and the initial state is restored. It becomes like this.

In the process of the door plate 5 moving to the closed position as described above, if the pachinko ball 30a gets caught between the door plate 5 and the upper edge 1a of the opening 1 as shown in FIG. The door plate 5 cannot be moved to the closed position. During this time, although the motor 17 is being reversed,
A slip mechanism 19 provided between the arm 18
As a result, the motor 17 continues to be driven, and after a certain period of time, the motor 17 is stopped. At this point, the arm 18 has not moved to the solid line position in FIG. 2, and the opening/closing lever 16 cannot be prevented from rotating upward. Therefore, the moment the motor 17 stops driving, the door is opened. The plate 5 is opened again by the bias of the weight 6.

As the door plate 5 is opened in this manner, the stuck pachinko balls 30a pass through the receiving chamber 8 and are discharged from the outlet 9 to the gutter 31. At this time, the ball detection signal obtained from the micro switch 12 is transmitted to the timer 27 via the contact piece 25a and the terminal
is supplied to As a result, the timer 27 is activated and the motor 17 is reversed again via the terminal b of the motor drive circuit 24, so the door plate 5 is rotated toward the closed position and the door plate 5 is opened. It is possible to reliably prevent this situation from occurring. Furthermore, even if more pachinko balls are placed on top of the bitten pachinko balls and the door plate 5 is opened again and two or more winnings are detected, these will still be counted by the counter 26. Therefore, the door plate 5 and the counter 26 are reliably returned to their initial states.

[Effect of idea]

As described above, in the winning ball receiving device of the present invention, when a certain number of winning balls pass through the open door plate and the motor is driven to close the door plate, the winning balls pass through the door plate again. When a surplus prize is detected, the motor is driven again to close the door plate again. Therefore, it is possible to reliably prevent the door plate from being left open due to pachinko balls getting caught.
