Description

[Detailed Description of the Invention] [Purpose of Invention] (Industrial field of application) The present invention is one in which a hit ball that has returned to the game surface and has jumped through the discharge port, and a glass plate that is stagnant on the game surface. The present invention relates to a pachinko machine that prevents balls falling when the door is opened from flowing into the launch rail.

(Prior Art) In a conventional pachinko machine, as shown in FIG. 6, the rail is divided into a launch rail 1 and a guide rail 2, and a ball discharge port 3 is provided between the rails 1 and 2. In this case, the ball fired from the launching device 4 follows the locus shown by the double-dashed line arrow A in the figure to jump from the launch rail 1 to the guide rail 2 and then from the guide rail 2 to the game surface. It has become.

Most of the balls that could not reach the game surface for some reason descended along the guide rail 2 as shown by the dotted arrow B in the figure, then entered the discharge port 3 and were removed from there into the ball tray. It is supposed to be done.

(Problems to be Solved by the Invention) In the configuration described above, the ball launched by the launching device 4 and the return ball collide with each other on the guide rail 2 or bounce up for some reason. As shown by arrow C, the discharge port 3 may be skipped and fall on the launch rail 1. At that time, the next ball to be fired is often already waiting at the firing position, and two balls must be fired at the same time, which makes it impossible to cause the ball to jump to the game surface. Also, if the ball catches on a nail or accessory during the game, it may stagnate as it is, and the solution is to open the glass door and remove it, but at this time the stagnation ball falls on the launch rail. This is the same state as when the return ball jumps over the discharge port and returns.

The present invention has been made in view of the above circumstances, and its purpose is not to drop the return ball that jumps over the discharge port and the stagnation ball that drops when the glass door is opened to the launch rail, but all the ball receiving tray. It is to provide a pachinko machine that can be outsourced to others.

[Construction of the Invention] (Means for Solving the Problems) The pachinko machine of the present invention is provided with a board having a launch rail attached to the lower side of the game board, and covers the game board with a glass door that can be opened and closed. In the one in which the substrate is covered with an openable / closable closing plate, a ball receiving member formed so as to limit the escape of the received ball to the ball outlet is installed above the launch rail with a ball passing space, The ball receiving member is set to have a size such that there is no gap exceeding the radius of the ball between itself and the base plate or the closing plate when the closing plate is closed, and at least the entire length of the launch rail is covered. It is a thing.

(Operation) Even if the ball is jumped over the discharge port due to a collision between the ball emitted by the launching device and the return ball, the ball is received by the ball receiving member and removed from the ball outlet.

Further, the ball receiving member covers the entire length of the launch rail without causing a gap exceeding the radius of the ball to exist between the launch rail and the base plate or the closing plate, and the stagnant ball drops when the glass door is opened. Since it is also received by the ball receiving member and removed from the ball outlet, the ball does not return to the firing position.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

First of all, the schematic configuration of the entire pachinko machine is as shown in FIG. 4, in which a game board 12 is provided in the main body 11 and a board 14 provided with a launching device 13 is provided under the game board 12. Board
The game board 12 and the board 14 are mounted flush with each other, and are covered with a glass door 15 and a ball supply unit board 16 as a closing board, respectively. A ball tray 17 and an operation handle 18 are provided on the lower front surface of the main body 11.

Now, on the front surface of the board 14, the tip of the launch rail 20 that constitutes the rail 19 and the base of the guide rail 21 that rises clockwise in the left half toward the game board 12 are attached substantially horizontally apart. A discharge port 22 described later is opened between the rails 20 and 21. Then, on the launch rail 20, the balls are supplied one by one from the supply mechanism 23 provided on the ball supply unit plate 16. As shown in FIG. 3, the launching device 13 comprises a ball striking rod 24 and a cam 25 rotated by a motor (not shown). When the roller 26 of the ball striking rod 24 is disengaged from the rotating cam 25, The ball striking rod 24 is swung in the direction of arrow D by the elastic force of a spring (not shown), and is stopped at the firing position by an L-shaped bent portion 20a formed at the lower end of the firing rail 20. It is designed to hit a ball.

On the other hand, on the front side of the sphere supply unit plate 16, as shown in FIG. 4, a sphere supply tray 27 is provided, and from this sphere supply tray 27, an alignment path 28 for aligning the spheres in a line is provided. Supply mechanism
It is extended so as to descend downward toward 23. still,
On the back side of the ball supply unit plate 16, there is provided a prize ball receiving opening 29 connected to the ball supply tray 27, and this prize ball receiving opening 29 is communicated with a prize ball discharging opening 30 formed on the game board 12. Then, when the balls hit on the game board 12 enter the winning opening, a predetermined number of winning balls are supplied from the winning ball discharging port 30 through the winning ball receiving port 29 to the ball feeding plate 27. .

Now, as shown in FIG. 1 and FIG.
Between the guide rail 21 and the guide rail 21, a discharge tube 31 is disposed as a discharge path having a return ball discharge port 22 at the upper end opening. The discharge tube 31 has a lower end portion on the ball receiving tray 17. The ball is communicated and the returning ball is discharged to the ball tray 17.
On the other hand, a ball receiving plate 32 as a ball receiving member is arranged on the back surface of the ball supply unit plate 16. The ball receiving plate 32 is positioned on the firing rail 20 when the ball supply unit plate 16 is closed, and its width is such that the rear end surface of the ball receiving plate 32 is substantially in contact with the substrate 14. The distance between the sphere supply unit plate 16 and the sphere supply unit plate 16 is set to be approximately the same. The ball receiving plate 32 is bent and formed so that its upper surface is concave, for example, in an inverted V shape, and one side of the bent portion is spaced apart from the firing rail 20 by a distance slightly larger than the diameter of the ball F. It extends to a discharge port 22 in parallel with the firing rail 20 with a (sphere passing space). The other side of the bent portion of the ball receiving plate 32 is extended beyond the L-shaped bent portion 20a of the firing rail 20 to the outside thereof, and a blocking piece 32a is formed upright at its extended end. A ball outlet 33 is formed in the bent portion of the ball receiving plate 32,
The ball outlet 33 is connected to a ball game passage 35 provided on the front side of the ball supply unit plate 16 via a ball removing cylinder 34. Then, when the ball supply unit plate 16 is closed, the outlet of the ball passage 35 is connected to the receiving port 31a formed in the discharge tube 31.

Incidentally, as shown in FIG. 3, the end portion of the alignment path 28 is an opening / closing plate.
When the opening / closing plate 36 is moved in the direction of arrow J against the spring force of a spring (not shown), the alignment path 36 is formed.
The balls in 28 are discharged into the ball-passing passage 35.

Next, the operation of the above configuration will be described.

The sphere F is housed in the sphere supply tray 27, and the operation handle 18 is operated. Then, the cam 25 is rotated by a motor (not shown), and the ball striking rod 24 repeats a ball striking ball preparing operation in which it swings in the direction opposite to the arrow D and a ball striking operation in which it swings in the direction of the arrow D by the elastic force of a spring (not shown). , Balls are launched one after another on the game board 12.

However, the ball shot by the batting rod 24 may not roll out from the guide rail 21 to the game board 12 for some reason, but may roll down the guide rail 21 as it is. Then, the return ball falls from the guide rail 21 into the discharge port 22 as shown by a dotted arrow K in FIG.
Discharged to 17. In this way, in the normal case, the return ball is dropped from the guide rail 21 into the discharge port 22 and
It is ejected to 17, but depending on the timing, the launching device 13
The ball may fly over the discharge port 22 as shown by the double-dashed line arrow L in FIG. Then, the ball jumping over the discharge port 22 falls on the ball receiving plate 32, rolls down on the ball receiving plate 32, enters the ball removing cylinder 34 through the ball removing port 33, and removes the ball removing passage 35 and discharge. It is discharged to the ball saucer 17 through the tube 31. Therefore, even if the return ball jumps over the discharge port 22, there is no problem that the ball falls onto the launch rail 20 and returns to the launch position, and the hitting rod 24 is in a state of launching two balls at the same time. It can be effectively prevented.

By the way, as shown in FIG.
The nails 37 may interfere with the balls, and the balls that are launched one after another may be caught and stuck in a "grape shape". In this case, the glass door 15 is opened and the ball is taken out. At this time, the clogged ball may drop at once and enter between the substrate 14 and the ball supply unit plate 16. In such a case, in this embodiment, since the ball receiving plate 32 is provided so as to cover the entire firing rail 20 from above, the ball inserted between the substrate 14 and the ball supply unit plate 16 is The ball is received by the ball receiving plate 32 or the guide rail 21, and then discharged from the ball outlet 33 or the outlet 22 to the ball tray 17. Therefore, unlike the conventional case where the ball receiving plate 32 is not provided, there is no problem that the ball falls from the game board 12 onto the launch rail 20 and rolls down to the launch position.

Here, in order to prevent the ball from falling from the game board 12 onto the launch rail 20, the ball receiving plate 32 is set to L of the launch rail 20.
It is not necessary to extend beyond the character-shaped bent portion 20a to the outside thereof, as long as it can cover the entire length of the firing rail 20 from one end to the other end from above. Further, there may be a gap between the ball receiving plate 32 and the substrate 14 or the ball supply unit plate 16 to the extent that the radius of the ball is not exceeded. This is because if the gap is such that it does not exceed the radius of the ball, the ball will not fall into the gap and stop, and will roll over the upper surface of the ball receiving plate 32 and be removed from the ball outlet 33.

Although the ball receiving plate 32 is attached to the ball supply unit plate 16 in the above-described embodiment, it may be attached to the substrate 14 as shown in FIG. While being closed by the unit plate 16, the lower end portion of the ball removing cylinder 34 is provided with a hole 16a formed in the ball supply unit plate 16 for removing the ball passage 3
It should be configured to communicate with 5.

[Advantages of the Invention] As described above, according to the present invention, the following effects can be obtained.

That is, the ball receiving member formed so as to limit the escape of the received ball to the ball outlet is installed above the launch rail in the space for passing the ball so that the return ball may jump over the outlet. In this case, since the return ball can be received by the ball receiving member and discharged from the ball outlet, the return ball does not return to the firing position of the rail.

Also, since the ball receiving member is set to a size that does not have a gap that exceeds the radius of the ball between the base plate and the closing plate when closing the closing plate and covers at least the entire length of the launch rail, it has stagnated on the game board. Even if the ball falls by opening the glass door, it can be received by the ball receiving member and discharged from the ball outlet, so that the returning ball does not return to the firing position of the rail.
