Description

[Detailed description of the invention] The present invention relates to a device that automatically feeds pachinko balls from a ball tray installed at the front of a pachinko machine one by one to the firing position of a firing rail in conjunction with the firing operation of a ball rod. It is designed to stabilize the supply operation of balls to the firing position and prevent uneven supply.

Conventionally, this type of automatic ball supply device guides the pachinko balls in the ball tray to just before the supply port at the firing position, and moves the balls by swinging the ball feeder in conjunction with the firing operation of the ball rod. These are sent out one by one from the supply port to the firing position. In other words, in the conventional device, the ball sending body receives one hit ball into the ball receiving part by raising its tip, and sends the ball to the firing position by lowering its tip, and at the same time, the ball stopper sends the ball to the ball receiving part. A seesaw action is continuously performed to prevent the ball from being received, and the balls are automatically fed one by one from the supply port to the firing position. However, in the conventional device having the above configuration, when the tip of the ball feeding body is lowered, the ball dancing phenomenon occurs due to the reaction, and as a result, the ball stopping stopper becomes inaccurate in stopping the next ball, resulting in uneven feeding. This resulted in a drawback that made the firing operation extremely difficult.

In view of the above-mentioned points, the present invention is constructed so that the next ball to be sent to the firing position is placed on the upper surface of the ball feeder and held in place, thereby completely eliminating unnecessary movement due to the reaction of the ball feeder and allowing the ball to be fired. It was devised to automatically supply balls to the correct position.

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

1 is a pachinko machine main body, 2 is a front frame thereof, and 3 is a game board attached to the inner surface of a window hole of the front frame 2, on the surface of which a firing rail 4 and a guide rail 5 are provided. At the firing position 4a of the firing rail 4, there is a striking rod 6.
The tip of the is facing out. 7 is a front decorative plate that covers the lower part of the launch rail 4 and the guide rail 5;
It is attached to the front frame 2 together with a glass frame 8 covering the upper part thereof so as to be openable and closable. The front decorative plate 7 is provided with a communication port 9, and a bead plate 10 communicating with the communication port 9 is fixed to the surface.

The automatic ball supply device a according to the present invention has a front decorative plate 7.
It is located on the inner surface of and is provided in communication between the communication port 9 and the firing position 4a of the firing rail 4. As shown in FIG.
An inclined passage 13 is formed that slopes downward from the ball inlet 12, and a supply port 14 corresponding to the firing position 4a is further provided in front of the inclined passage 13.
Reference numeral 15 denotes a ball feeding body which is swingably attached to the device frame 11 by a shaft 16, and has a ball cutting stopper 17 at the end opposite to the downstream end of the inclined passage 13, and sends the balls to the supply port 14 on the upper surface. It is integrally formed with a guiding portion 18, and is normally urged to rotate downward by a weight 19 so as to be placed in a position communicating with the inclined passageway 13.

In addition, a through hole 20 is provided in the ball feeding body 15 at a position spaced apart from the end of the inclined passage 13 by one pachinko ball, and a ball stopper piece 21 facing the through hole 20 is provided.
is provided protruding from the device frame 11. The ball stopper piece 21 protrudes from the upper surface of the ball feeder 15 when the ball feeder 15 is in communication with the inclined passage 13, and stops and holds one ball on the upper surface of the ball feeder. The height position is set such that when the ball 15 is pushed upward, it sinks from the top surface and releases the restriction on hitting the ball.

Reference numeral 22 denotes an inverted L-shaped actuating member that is pivotally supported by a fulcrum shaft 23, and is connected to the lower part of the device frame 11 or the game board 3.
A hook rod 25 in which a roller 24 provided on an arm portion 22a extending laterally and pivoted on the surface of the ball feeder 15 is brought into contact with the lower surface of the ball feeder 15, and a lever portion 22b hanging downward is fixed to the ball hitting rod 6. linked to. Reference numeral 26 denotes a swinging guide plate which is located above the ball feeder 15 and is pivotally attached to the device frame 11 by a shaft 27, and when the ball feeder 15 is pushed up, it guides the balls that rest on the end of the ball feeder 15. The guide member 18 is brought into contact with the inclined lower surface of the guide member 18 and quickly moved in the direction of the guiding portion 18 . Reference numeral 28 is a stop rod that restricts the range of swing of the swing guide member 26, and 29 is a shutter plate that closes the ball entrance 12 via a bell crank 30 when necessary, such as when stopping the ball.

The present invention has the above-mentioned configuration, and its operation will be explained next. The pachinko balls in the ball tray 10 enter the ball inlet 12 from the communication port 9 and flow down the inclined passage 13 in a line, and the first hit ball B lands on the ball feeder 15 as shown by the solid line in FIG. It is stopped and held by a stopper piece 21. In this state, when the striking rod 6 is moved to the firing preparation position shown by the chain line in FIG. The roller 24 which swings and comes into contact with the lower surface of the ball feeder 15 pushes up the ball feeder 15 as shown by the chain line in the figure. With this, Tamakiri stopper 1
7 closes the downstream end of the inclined passage 13 to open the inclined passage 13.
At the same time as preventing the hit ball B ₁ from flowing down to the ball feeder 15, the ball stopper piece 21 sinks from the top surface of the ball feeder 15, and the ball that had been prevented from flowing down by the ball stopper piece 21 B moves to the guide part 18 and the supply port 14
The upper end of the barrel prevents the barrel from being sent out to the firing position.

Then, the striking rod 6 performs a firing operation and moves back as shown in FIG.
When the link is released, the ball feeder 15 is released from being pushed up by the roller 24 and returns to its original position communicating with the inclined passage 13 by the action of the weight 19.
As a result, the ball B, which has been stopped by the upper end of the supply port 14, is sent out from the supply port 14 to the firing position 4a by the inclined bottom surface of the guide portion 18, and at the same time, the ball B that has been stopped by the upper end of the supply port 14 is sent out from the supply port 14 to the firing position 4a. B ₁ is ball feeder 1
The ball rests on the upper surface of the ball 5 and is stopped and held by the ball stopper piece 21, and by repeating the above operation, the balls are automatically supplied to the firing position 4a one after another.

As is clear from the above explanation, according to the present invention,
The balls in the ball tray are guided through an inclined passage to the supply port corresponding to the firing position of the firing rail, and the first ball lined up in the inclined passage is guided by a ball feeder that is always linked to the firing operation of the ball rod. Since it is configured to be placed on the top surface and restrained and held, the weight of the ball placed on the top surface reliably prevents unnecessary movement of the ball feeder caused by the reaction that occurs when the ball is sent to the firing position. With this, accurate automatic supply of balls can be achieved.
