Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a winning ball receiving device for a pachinko machine. This invention relates to a winning ball receiving device that prevents the device from becoming unable to close.

[Conventional technology]

Pachinko machines are equipped with various winning ball devices,
I try 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 of 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 way, an electromagnetic drive device such as a solenoid or a motor, and an interlocking mechanism installed between this drive device and the door plate are used. The door plate is opened when an opening signal is generated from the winning section. Then, the number of pachinko balls that won through the opened door plate is counted by a counter.
For example, when the number reaches 10, the door plate is closed.

[Problem that the invention attempts to solve]

However, in the conventional winning ball receiving device using the door plate as described above, in the process of moving the door plate to the closed position, the upper edge side of the door plate and the opening that should be covered by the door plate are removed. A pachinko ball may get stuck between the lower edge of the If this situation occurs, the door plate will remain in that position in a half-open state, causing balls to become jammed on the board surface. Furthermore, in the case where the door plate is opened and closed by a motor, the current supply to the motor is cut off after a certain period of time has elapsed. However, as mentioned above, if the motor stops before the door plate completely returns to the closed position, the weight attached to the front of the door plate will force the door to open. The board becomes open again.

This invention was made to solve the above-mentioned drawbacks of the conventional technology, and when closing the door plate, the door plate does not stop midway through closing due to pachinko balls getting caught. An object of the present invention is to provide a winning ball receiving device for a pachinko machine.

[Means for solving problems]

In order to achieve the above object, when the door plate is in the closed position and the opening is closed, the rotating shaft of the door plate is attached to one side of the opening facing the rotating edge of the door plate. It is provided with a rotating piece that can freely rotate around parallel axes. Then, when the pachinko ball is caught by the door plate while the door plate is rotating from the open position to the closed position and is about to be pinched between the door plate and the rotating piece, the rotating piece It is pushed in and rotated by the pachinko ball.

According to a preferred embodiment of the present invention, the opening and the door plate are formed in a horizontally long rectangular shape, and the door plate is provided with a pivot axis along its lower edge, and its upper edge is a pivot edge. It's summery. The rotating piece is rotatable about an axis along the upper edge of the opening so as to face the rotating edge of the door plate.

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 rectangular 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 the same (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. Weights 6, 6 are integrally attached to both front sides of the door plate 5, so that the door plate 5 is always biased in the opening direction.

A rotating piece 8 is attached to the upper edge 1a of the opening 1 via shafts 7, 7. The rotating piece 8 has a width that is approximately the same as the width of the opening 1, and a vertical width that is smaller than the outer diameter of the pachinko ball, and usually hangs down due to its own weight. After the pachinko balls that entered through the opening 1 reach the receiving chamber 9 formed behind the opening 1,
It is discharged from the outlet 10. A detection lever 1 is installed on the back side of the receiving chamber 9 so as to face the outlet 10.
1 is pivotally mounted so as to be swingable, and the detection lever 11 is swinged by a pachinko ball passing through the outlet 10 and on its way to the gutter 31. This swinging of the detection lever 11 is caused by the micro switch 12
is detected as an electrical signal by

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 pivoted to a support plate 15 is engaged with the engagement lever 14, and an arm 18 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 can be rotated 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 that causes the motor 17 to rotate forward for a certain period of time is supplied to the input end a of the motor drive rotation path 24. 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. At this point, the motor 17
drive has been stopped.

The pulse signal from the Yakumono winning determination section 22 is
It is also input to a set/reset type flip-flop circuit 25. As a result, the Q terminal of the flip-flop circuit 25 becomes high level, which causes
It is supplied to one terminal of the AND circuit 26. The micro switch 12 provided facing the exit 10 outputs a ball detection signal as a high-level signal pulse every time a pachinko ball passes the exit 10, which is counted by a counter 27 via an AND circuit 26. will be done.

In this way, the number of pachinko balls won through the door plate 5 is counted by the counter 27, and when the number reaches 10, the counter 27 outputs a 10 count signal. This 10 count signal is the timer 28
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. Furthermore, the 10 count signal output from the counter 27 resets the count value of the counter 27 and at the same time also resets the flip-flop circuit 25, and its Q terminal output becomes low level again and returns to the initial state. .

By the way, when a pachinko ball is received by the door plate 5 while the door plate 5 rotates from the open position to the closed position, as shown in FIG. Pachinko ball 30 has opening 1
being sent to. Since the upper side of the pachinko ball 30 pushes in the rotating piece 8 and rotates, the pachinko ball 30 is ensured to reach the inside of the receiving chamber 9. Therefore, a phenomenon in which pachinko balls are pinched between the door plate 5 and the upper edge 1a of the opening 1 does not occur, unlike in the conventional case. Note that since the length of the vertical side of the rotating piece 8 is narrower than the outer diameter of the pachinko ball 30, when the door plate 5 is in the closed position, the rotating piece 8 is pushed away and the pachinko ball enters the receiving chamber 9. There is no such thing.
In addition, when implementing the present invention, the opening/closing lever 16
Instead of operating the motor 17, a solenoid may be used.

[Effect of idea]

As described above, in the winning ball receiving device of the present invention, a rotating piece is provided on one side of the opening that is opened and closed by the door plate, and when a pachinko ball is pushed in by the rotating edge of the door plate, the pachinko ball This allows the rotating piece to escape. Therefore,
Pachinko balls are not pinched between the opening and the door plate, and the door plate can be reliably rotated to the normal closed position.
