Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a device that opens the ball entrance of a mounting plate to receive winning balls, and in particular, it has a simple structure and accurately counts a predetermined number of winning balls. This invention relates to a winning acceptance device for a pachinko machine which opens and closes a ball entrance.

(Prior Art) Conventionally, as a prize acceptance device for a pachinko machine, the one described in Japanese Utility Model Publication No. 57-24381 is known.

As shown in FIGS. 6 and 7, a door plate 3 is attached to a ball entrance 2 provided on a mounting plate 1 so as to be openable and closable.
A box frame 6 in which a ball passage 5 that communicates a solenoid 4 for opening and closing the door plate 3 and a ball entrance 2 is formed inside.
It is assembled into one piece.

A detection switch 8 is placed facing the exit part 7 of the ball passage 5, and the detection switch 8 counts the winning balls 9 entering the ball entrance 2. When the number of winning balls 9 reaches a certain number, the solenoid 4 is activated. It is characterized in that the detection switch 8 and the solenoid 4 are electrically related so as to close the door plate 3 which is in an open state.

(Problems to be Solved by the Invention) However, in the above device, in order to count the winning balls, the ball path is provided with a certain length to sequentially line up the winning balls that fly into the ball.
Therefore, the detection switch is provided at the outlet of the ball passage, and there is a considerable distance from the door plate to the detection switch.

In other words, there remains room for storing winning balls between the ball passages.

Therefore, after a certain number of winning balls are taken into the ball entrance and the detection switch counts a predetermined number of winning balls, the solenoid is activated and the door plate is closed. There is a danger of the ball flying into the ball entrance.

Furthermore, the above-mentioned time lag occurs in the means for detecting winning balls of this device due to the configuration described below. It is located behind the ball exit 7,
The opening/closing member 11 whose base end is swingably supported by a shaft 10 is used and its arrangement.

This opening/closing member 11 is integrally formed with a ball receiving part 12 that receives the winning balls 9 flowing out from the ball outlet 7, and a shutter part 13 that closes the ball outlet 7 when the ball tilts downward due to the weight of the balls. .

Therefore, the winning balls 9 are sent one by one to the ball passage exit 7.
The ball is received by the ball receiving part 12, and the opening/closing member 11 tilts due to the weight of the opening/closing member 1.
The detection switch 8 counts the winning balls 9 by pressing the operating protrusion 14 of the detection switch 8 provided on the lower side. Moreover, the path of the next winning ball is blocked by the shutter member 13 and is in a waiting state.

That is, the detection switch and the accompanying opening/closing member ensure that the winning balls are counted one by one, and the winning balls are regulated to be rectified at the exit section.

For this reason, since it is provided with a shutter member that separates a plurality of winning balls individually, they cannot pass through the exit section continuously at once. Therefore, even if accurate counting is possible using the detection switch,
It does not have a device that continuously counts winning balls without stopping the flow.

Therefore, by providing the winning ball detection unit at the exit of the ball passage for structural reasons, its response is slow, so it is necessary to count a predetermined number of winning balls and then close the door plate. A problem arose in that extra winning balls were introduced into the ball passage.

In addition, the mechanism of the opening/closing member 11 as a movable part is complicated, and it is difficult to maintain accuracy for a long period of time.
In addition, maintenance was also a problem.

Therefore, in order to solve the above-mentioned problems, the present invention is designed to immediately ascertain the exact number of winning balls without stopping the flow even if a large number of winning balls fly into the ball entrance in succession, and to determine the number of winning balls to a predetermined number. To provide a winning acceptance device for a pachinko machine which prevents the reception of extra winning balls and has a simple configuration with fewer mechanical troubles.

(Means for Solving the Problems) In order to achieve this purpose, the present invention provides a ball entrance having a door plate that can be opened and closed freely on a mounting plate fixed on the game board, and communicates with the ball entrance. A frame body forming a ball passage;
The rear side of the mounting plate is equipped with a solenoid for opening and closing the door plate, and a detection switch having a passage hole for winning balls at a ball passage position facing the ball entrance, and the door plate is provided with a hole for passing the winning ball at a ball passage position facing the ball entrance. It is characterized by having an opening regulating member that determines the angle, and a ball receiving plate that is provided at the bottom of the door plate and forms a ball passage for guiding winning balls to the passage hole of the detection switch with the back surface of the door plate. It is said that

(Function) Since the present invention has the above configuration, when the solenoid is activated, the door plate of the ball entrance rotates forward to open the ball entrance. For this reason, the opening of the ball inlet becomes large, and the balls are easily received by the door plate and fly into the ball inlet.

The winning balls that have entered the ball roll through a ball path with a V-shaped cross section formed by the back surface of the door plate and the ball receiving plate, and fall into the passage hole of the detection switch from the notch in the center of the rolling ball receiving plate.

In this case, the mounting plate and the frame surround the ball passage, and once the winning balls fly into the ball entrance, they are always guided along the slope of the ball receiving plate without straying elsewhere. The balls roll and fall into a predetermined passage position, that is, into the passage hole of the detection switch, and the winning balls can be counted continuously without stopping the flow, and the door plate can be closed immediately after the predetermined number of balls have been counted. The machine becomes a prize receiving device that accepts a predetermined number of winning balls.

(Example) Embodiments of the present invention will be described based on the drawings.

In Figures 1 to 5, 20 is the game board 2.
This is a mounting plate fixed with nails or the like on the mounting plate 1, and a ball inlet 22 is provided approximately in the center thereof, and is large and horizontally long so that several balls can be received at a time.

At the lower side of the ball entrance 22, there is a shaft 2 on which the door plate 23 is fitted into bearings 23a and 23b at both ends.
4 and 24, it is rotatably attached to the mounting plate 20. This door plate 23 has an engaging arm 25 protruding from the side edge of its back surface, extends downward from the back surface, is inclined from both sides toward the center, and has a ball receiving plate 26 with a part cut out in the center. has been established.

On the other hand, the front surface of the door plate 23 is provided with fan-shaped opening regulating members 27, 27 extending from both sides thereof, and the protrusion 28 on the lower front surface of the opening regulating member 27 hits the mounting plate front surface 20a. By touching the door plate 2
The opening angle of the ball inlet 22 of No. 3 can be specified to a predetermined angle.

Moreover, this opening degree regulating member 27 acts as a weight for balancing the door plate 23 in the direction of always opening. Preferably, the tension coil spring 30 is fitted to the outer periphery of the bearing portion 23b on the side having the engagement arm 25, and a brass metal screw, rivet 29, etc. is embedded in the front part of the opening regulating member 27. The door plate 23 can be opened more stably. This door plate 23 is opened and closed by the mounting plate 2.
By the operation of the solenoid 40 provided at the rear of the
The plunger 42 is moved up and down via the operating lever 33.

On the back side of the mounting plate 20, there is a frame 31 that surrounds the ball entrance 22 from the rear and both sides, and this frame 31
is made of the same material as the mounting plate 20 here, and is integrated with the mounting plate 20 by tightening with several screws 32, .

The frame body 31 is provided with an arm portion 34 that supports an operating lever 33 for opening and closing the door plate 23, and a detection switch 35 for counting a predetermined number of winning balls B at a predetermined ball passage position below the ball entrance 22. A supporting member 36 and the like are integrally formed. The support member 36 has a concave support portion 37 surrounding the upper surface and both side surfaces of the detection switch 35, and a locking portion 38 having spring properties.

The arm portion 34 projects to the rear of the frame 31 and pivotally supports a horizontal shaft 33a at the rear end of the operating lever 33, thereby allowing the operating lever 33 to swing freely. Further, the tip of the actuating lever 33 is positioned on the upper surface of the engaging arm 25.

The detection switch 35 is a non-contact proximity switch shown in FIG. 3, and is provided with an octagonal or round hole passage 35a through which the winning balls B pass. One pole of a magnet is brought into contact with the wall of this hole passage 35a, and a Hall element to which a constant current is supplied is arranged at a symmetrical position so that it can receive magnetic flux from the magnet, and when a metal sphere passes through it, The output voltage of the Hall element is detected by the magnetic change that occurs. Thereby, the number of winning balls B is counted.

The solenoid 40 is assembled to another mounting frame fixed to the rear side of the mounting plate 20 together with a printed circuit board (not shown), and a spring 43 is wound around the plunger 42 of the solenoid 40.

The spring 43 is located between the bottom of the solenoid 40 and an L-shaped fitting 44 that is integrated with the plunger 42 and also serves as a spring seat. When the solenoid 40 is demagnetized,
The plunger 42 is lowered by the action of the spring 43 and rotates the operating lever 33 in the direction of arrow P. Therefore, the engaging arm 25 is pushed down, and the door plate 2
3 will close the ball inlet 22.

The solenoid 40 is energized when a hit ball enters a specific winning hole on the game board surface or when preset game conditions are met, and the plunger 42 attracts the solenoid upward against the spring 43.

As a result, the operating lever 33 rotates in the opposite direction of the arrow P and releases the pressure on the engagement arm 25, so that the door plate 23 opens due to its own weight and the action of the tension coil spring 30. After opening this door plate 23, the detection switch 35
When the solenoid 40 counts a certain number of winning balls B, the solenoid 40 is demagnetized and the plunger 42 is lowered to press the operating lever 33. As the operating lever 33 rotates, the engaging arm 25 rotates together with the door plate 23 to close the ball entrance 22.

In addition, as is clear from the front view shown in FIG.

In other words, when the number on the accessory's LED display reaches 777, the door plate will be opened for a predetermined period of time. This door plate 23 is a winning ball B within a set time.
The circuit is configured so that it closes when a predetermined number of numbers fly in and are counted, or when the time elapses even if the predetermined number is not reached.

In this embodiment, an accessory having a three-seven function is used, but the prize receiving device of the present invention may be used in combination with other accessories, or the device may be used alone.

In addition, as the opening regulating member that determines the opening angle of the ball inlet, in this embodiment, fan-shaped members are provided on both the left and right sides of the door plate and contact the front surface of the mounting plate, but instead of this, when the solenoid is attracted , L-shaped fitting 4
The opening degree of the ball entrance may be determined by raising the operating lever 33 connected to the opening 4 and restricting the upward rotation of the engaging arm at a predetermined position. A stopper member protruding from the side wall 41a may be provided, and the opened door plate may be brought into contact with this stopper member to determine a predetermined opening degree of the ball inlet.

(Effect of the invention) As is clear from the above explanation, the present invention narrows the distance between the ball entrance and the detection unit by providing the detection switch for counting winning balls in the ball path facing the ball entrance. At the same time, the ball receiving plate integrally formed on the door plate forms a ball passage that guides the ball to the passage hole of the detection switch between the back surface of the door plate and the ball receiving plate, so the door plate can be opened and closed quickly with a simple configuration. You can accurately count winning balls.

Furthermore, since the structure is simple, it is easy to assemble and is inexpensive, and there are also advantages in terms of maintenance, such as fewer failures.
