Description

[Detailed description of the invention] The present invention relates to a pinball game machine, and more specifically to a pinball game machine.

This invention relates to a new pinball game machine in which the balls and the game top are separate and a part of the balls supplied as prize balls is fired directly onto the game board surface as a game top.

A commonly used pinball game machine has a spiral guide rail on the surface of the game board, and a firing position is provided at the lower end of the guide rail. The rental balls in the ball tray are directly launched as tiled game balls onto the game board surface, as if they were guided to the firing position and fired onto the game board surface.

It is.

However, in the conventional pinball game machine having the above configuration, not only does the dirt from the rented balls adhere to the surface of the game board, spoiling its aesthetic appearance, but the dirt on the balls also makes it difficult to get the ball to come out easily. It's easy to tell whether the table is there or not.

Therefore, there was a drawback that the work time after the store was closed was longer, such as the need to wipe down the board surface every time the store was closed.

Also, for example, Publication of Utility Model Publication No. 47-20685, Publication of Utility Model Publication No. 5
In the case of a pinball game machine in which a firing position is provided on the upper side of the game board as shown in Publication No. 0-44220 and Publication No. 50-44221, the rented balls can be used as they are in the game. If you try to fire balls onto the board, you will have to install the ball tray into which the rented balls are thrown above the machine itself, so the relative position of the ball tray and the prize ball ejecting mechanism provided on the back of the game board must be adjusted. Due to the relationship, it is absolutely impossible to guide the prize balls that are ejected for each winning ball to the ball tray, and therefore the ball tray must be refilled frequently during the game, which is extremely troublesome and impractical. It becomes unworthy to be served.

One object of the present invention is to guide balls in a prize ball replenishment gutter located above the main body of the game machine directly to the shooting position as playing balls, apart from rented balls and playing balls, so that the balls are constantly polished. To provide a new pinball game machine capable of firing balls without staining the game board surface.

Another object of the present invention is that even in a pinball game machine in which the firing position is provided at the upper side of the machine, separate from the rental balls and the top of the game, the ball receiving tray into which the rental balls are thrown is located at the bottom of the gaming machine main body.

The present invention has the above-described structure, and its operation will be explained next.

First, the balls supplied to the prize ball tank 15 from the prize ball supply gutter 18 disposed above the gaming machine main body are transferred from the lead-out gutter 16 to the branch gutter 46, where two parts of the balls are fed as game balls other than the prizes. It is guided through the gutter 4γ to the introduction hole 38 and is continuously supplied into the guide passage 35 communicating with the firing position 9.

At this time, as shown in FIGS. 6 and 7, the first game ball B fits into the special part 37 formed in the guide passage 35, is prevented from moving to the firing position 9, and remains at that position. It will be done.

On the other hand, when the player puts rented balls into the upper ball tray 5, the balls continuously face the outer peripheral surface of the rotating disk 57 from the ball outlet 25 through the inlet 50.

When the rotating bundle 7 is rotated in the direction of the arrow shown in FIG. 1 in this state, the take-up pulley 83 fixed to the shaft 81 is rotated, the cam piece 82 closes the microswitch 84, and the motor 55 is started. The rotating disk 51 rotates in the direction of the arrow in FIG.

When the leading rental ball B1 matches the fourth part 58 of the rotating disk 57, the rental ball B1 enters the recess 58, and the 12th rental ball B1 enters the recess 58.
As shown in the figure, as the rotating disk rotates 570 times, the rental ball B
1 pushes up the detection piece portion 71a of the rental ball detection member 71.

In response to this operation, the swinging member 59 moves the operation piece 71 of the ball rental detecting member 71 that comes into contact with the protruding edge 73 of the upper arm 64.
The roller 63 at the upper end of the plate cam 60 is swung by the plate cam 60.

Immediately before the tip bent portion 91 of 0b, that is, the firing rod 8
Move to a very close position where it does not affect 0b.

As the rotating disk 57 continues to rotate, the plate cam 60 acts on the roller 63 as shown in FIG.
9 is further swung in the direction of the arrow, and at the same time, the firing rod 80b is pulled in the direction of the arrow by the action pin 65 against the spring 90.

When the firing rod 80b is pulled, the firing rod 80a moves upward via the connecting plate 78, rotating the firing hammer 27 from the solid line in FIG. 5 to the chain line.

As a result, the control piece 39 of the firing hammer 27 rushes into the guide passage 35 from the opening 36 and pushes the leading game section B located in the special machine section 37, causing the game section B to go over the special machine section 37. and move it to firing position 9.

When the rotary disk 57 makes one rotation, the roller 63 of the swinging member 59 moves away from the plate cam 60 and returns to its original state due to the action of the spring 68, as shown in FIG. The firing rod 80b, which was engaged and pulled, is released from the engagement and becomes free.

As a result, the firing hammer 27 instantaneously returns to the state shown by the solid line in FIG. 5 due to the action of the spring 900, and the hammer head 4
0 causes the gaming section B at the firing position 9 to be fired at the gaming section 8a.

When the firing hammer 27 is in the state shown by the chain line in FIG. The firing hammer 27 returns to the state shown by the solid line in FIG.
is delivered to the special equipment section 37 within the guide passage 35.

In this way, the prize ball supply gutter 18 supplies one ball as a game part to the firing position each time the firing hammer 270 fires.

The rented ball B0 is discharged into a predetermined discharge path (not shown) while being guided by the guide frame 62 after rotating the rotary disk 57,070 times.

Among the game part B fired by the firing hammer 27 to the game part 8a, the out balls are discharged from the out ball opening 14 through the out ball ejection gutter 23 to the ejection path in the same way as the rented balls B. Ball drawer 21, winning ball discharge gutter 22
It is discharged to the discharge route through

Also, the prize balls released from the prize ball case 1γ by the entered prize balls are guided to the upper ball tray 5 through the prize ball discharge gutter 20, and can be used as rental balls for firing the game part.

In this embodiment, the motor 55 has a specification of 98 revolutions per minute, and 1. The rotary disk 57 rotates 98 times per minute by this motor 55, and 98 rental balls are transferred per minute, and the rental ball detection member γ is synchronized with each rental ball.
1. The game part is fired by operating the swinging member 59, the firing rods 8Qa and 80b, and the firing nosomer 27.

Further, if there are no rental balls, the rotating disk 57 simply spins idly, and the rental ball detection member 71 is not swung, so that the game section is not fired.

Further, in this embodiment, as shown in FIG. 7, a micro switch 92 for detecting game balls is provided at the end of the feeding gutter 47.
When the game part sending to the firing position 9 is interrupted, the microswitch 92 is activated to stop the motor 55, thereby preventing a situation where only the rented balls are ejected.

This makes it possible to have a complete one-to-one correspondence between the rental balls and the gaming section.

When the rotation angle of the rotating bundle 70 is adjusted, the spring 90 is
The tension of the ball is increased or decreased, and thereby the flight distance of the game part can be adjusted freely.

Also, if you release your hand from the rotating bundle 7, the rotating bundle 7
is returned to its original position by the action of spring 900, microswitch 84 is opened, and motor 55 is stopped.

As described above, the present invention separates the rental balls and the gaming section, and guides the balls of the prize ball supply gutter disposed above the gaming machine main body to the firing position of the gaming section provided on the surface of the gaming board. Because of this, the well-polished balls from the prize ball supply gutter are directly ejected onto the game board surface as a game part, completely preventing dirt from adhering to the board surface, and eliminating the troublesome wiping of the board surface. There is no need to do this at all, and the work time after closing can be significantly shortened.

In addition, by separating the rental balls and the gaming section, even if the shooting position is installed at the upper side of the game board, the ball tray into which the rental balls are thrown can be installed below the surface. Therefore, the disadvantages of the conventional pinball game machine can be eliminated, such as making it as easy to use as a general pinball game machine.
