[0002]

2. Description of the Related Art In a game machine of this type represented by a pachinko machine and an arrangement ball machine which are generally called, a ball receiving side is operated based on a cooperation between a hitting firing operation and a ball feeding operation by a game start operation. Is sent to the launch position one by one, and is launched into the game area of the game board so that a required game can be played. And such a gaming machine is configured to include a game board for each model, that is, various prize-winning devices and prize-winning devices, entrances and guides, arrangement of a large number of game nails (generally also referred to as a gauge). In the game area, various game boards that can develop the required game contents are set, and in the game on each game board, as a desired hit target portion of the game ball, for example, the left side in the game area, It is said that it is desirable to set the left side of the vertical center, the right side of the vertical center, the right side, and the like, and drive each of them toward a required part.

[0003] However, in any gaming machine capable of developing any game contents, the game balls hit into the game area one by one are effective balls for the game development and do not return to the firing position side. It is desirable. For this reason, techniques disclosed in Japanese Utility Model Publication No. 57-50061 and Japanese Utility Model Publication No. Hei 3-30138 have been proposed and implemented as means for preventing the game ball from returning.

[0004]

[Problem to be solved by the present invention]
No. 061, the “launching ball guiding device for pachinko machines” has an inner and outer mounting plate 12 attached to the game surface 9 as is clear from FIGS. 2 to 4. Rails 6, 7
A backflow preventing means, which is provided with a backflow prevention piece 11 that can open and close the discharge port 8 between the two, is set at the upper end of the inner rail 7 and a specific portion corresponding to the discharge port 8. In this embodiment, the blocking piece 11 opens and displaces the discharge port 8 to guide the hit ball a for each hit ball a hit, and returns from the game area to the firing position side. In the state where the blocking piece 11 closes the discharge port 8 for the hitting ball a, the hitting plate 11a receives the hitting piece 11 to prevent the backflow from the inside of the discharge port 8 downward.

That is, in this conventional device, the back-up prevention means is composed of a number of parts such as the blocking piece 11, the mounting plate 12, the shaft 13, and the biasing devices such as the magnets 16, 17 and the weight 19. In addition, there is a problem that the number of assembling steps is increased and inventory management is complicated. In addition, it is pointed out that the production cost is increased due to the large number of parts.

[0006] Further, in the "ball return preventing device for pachinko machine" disclosed in Japanese Utility Model Publication No. 3-30138, FIG.
As is clear from FIG. 8, a tongue piece 4 made of a thin elastic material is attached to the uppermost end of the inner guide rail 2 as a means for preventing reverse movement. In this embodiment, the tongue piece 4 is elastically opened and displaced to allow the ball to pass while being pushed and opened for each ball of the pachinko ball that has been struck out, while moving from the game area to the guide rail 2 side. The tongue piece 4 is received with the tongue piece 4 held in the normal closed position to prevent the ball from returning.

However, in this conventional apparatus, since the distance (interval) between the upper end of the tongue piece 4 and the outer guide rail 3 is smaller than the diameter of the ball and larger than the radius, the impact force of the reversing ball is reduced. On the other hand, the tongue piece 4 may be instantly pushed down below the two-dot chain line position in FIG. 1 to allow the ball return to the downstream side of the rails 2 and 3, and the original ball return prevention There is a problem that the function cannot be suitably performed. In addition, tongue piece 4

Are mounted on the guide rail 2. However, there is a problem that the number of parts for mounting increases in the case of the above method. In the other method, the attachment state of the tongue piece 4 to the guide rail 2 is weak, and there is a possibility that the tongue piece 4 comes off due to the contact of the ball. Further, in the method described above, before the guide rail 2 is fixed to the game board 1, the tongue piece 4 must be attached to the rail 2 in advance, so that the assembling work becomes complicated and the tongue piece 4 becomes necessary. The problem is that it cannot be easily removed in response.

It is designed to guide the passage of the ball B and to prevent the ball B from returning.

Therefore, first, regarding the guide rail 1 side, as shown in FIG. 5, a plurality (four in the drawing) of the required range of the upper end of the inner rail portion 3 with respect to the outer rail portion 2 is shown.
The locking holes 5, 5 are opened at equidistant positions to form a set portion 4 for the ball return preventing tool 11. The guide rail 1 is attached in a fixed arc shape around the front and outside of the game board P by using a split pin 8 or the like by a conventional assembling method, and the upper end of the inner rail portion 3 is illustrated. It is located on the upper left of the board. A space between the inner and outer rails 2 and 3 is a flight path 6 for a game ball, and an upper end surface of the flight path 6, that is, an opening surface at an upper end position of the inner rail 3 is formed as a launch port 7 of the game ball B. Have been. Further, each locking port 5 of the set section 4 is stamped together with a port 9 for the split pin 8.

On the other hand, the ball return preventing tool 11 is formed by stamping and bending a single thin metal elastic material (for example, a JIS standard material SUS301-CSPH having a thickness of 0.1 mm). As shown in FIGS. 2 to 5, a holding member which is formed into a size and a shape and which can be held and locked with respect to the set portion 4 of the guide rail 1 from the outside (upper side) in a form of being inserted. A blocking piece 20 for a game ball is formed in a series from one end of the portion 12. In the holding portion 12, an insertion port 15 is formed between the holding pieces 13, 14 which are formed in two folds and can be elastically pressed against the inner and outer surfaces of the inner rail portion 3 according to the thickness t of the rail. ing. A locking piece 16 is formed on the inner holding piece 14 so as to be able to elastically engage and disengage with the locking port 5. A lower end of the outer holding piece 13 has an insertion port 15. Are formed.

It is desirable that the entrance side of the insertion port 15 is slightly narrower than the thickness t of the rail. Each locking piece 16
Is appropriately bent obliquely toward the outer holding piece 13. An escape port 18 for the split pin 8 of the rail is formed in the inner holding piece 14 as necessary.

As shown in FIGS. 2, 3 and 5, the blocking piece 20 is formed in a band shape from a trapezoidal connecting portion 19 formed at a side end of the inner holding piece 14 of the holding portion 12. An outwardly concave arcuate arc portion 20b is formed to be able to elastically open and close the outlet 7 of the guide rail 1 toward the front of the linear portion 20a connected to the connecting portion 19. The blocking piece 20 is configured so that the arc portion 20b and the whole can be elastically deformed by the load of the ball or the impact force (contact force). In addition, the blocking piece 20 is formed in a band shape having a width that is approximately half the width (corresponding to the diameter of the sphere) and approximately twice as long as the inner holding piece 14 of the holding portion 12, and has an arc portion as an elastic characteristic. When a weight (static load) of one ball is applied to the tip of 20b, the whole is bent so that the tip can be displaced by a distance of about one ball. In the state where the holding portion 12 is engaged and held on the inner rail portion 3, the blocking piece 2
As shown in FIG. 2, the upper end portion 0 always extends toward the inner surface of the outer rail portion 2 to close the outlet 7.

[0017]

Next, the operation of the ball return preventing device of the present embodiment configured as described above will be described.

In the ball return preventing tool 11, as shown in FIGS. 1 to 4, in the game board P manufactured (configured) individually, it is simply inserted into a predetermined portion within the range of the set portion 4 of the guide rail 1. It can be locked and set simply by inserting it, and it is possible to guide the passage of the game ball B and to prevent the ball from returning. That is, the retaining portion 12 of the ball return preventing tool 11 is aligned with the engaging portion 16 and the engaging opening 5 with respect to the set portion 4 of the inner rail portion 3 and the guide edge 17 is positioned from the outside (upper side). The inner and outer holding pieces 13 and 14 are elastically pressed against the inner and outer surfaces of the inner rail portion 3 by being fitted using the insertion port 15, and each locking piece 16 is connected to the corresponding locking port. 5 is elastically engaged, and is locked in a state where displacement and detachment are prevented. A blocking piece 20 extending upward from the upper end of the inner rail 3 closes the outlet 7 and extends the upper end toward the inner surface of the outer rail 2.
It is set in a state in which.

Then, in the locked state of the ball return preventing tool 11 at a predetermined position, each ball of the game balls B, which are launched toward the game area A along the runway 6, is As soon as the blocking piece 20 comes into contact with the ball, it is elastically deformed so as to be pushed inward as a whole, and its tip is separated from the inner surface of the outer rail portion 2 to open the outlet 7 and pass the ball B. After the ball B has passed, the blocking piece 20 extends its original position, that is, the upper end portion toward the inner surface of the outer rail portion 2 by its own elastic force, thereby opening the outlet 7. The state is returned to the closed state (see FIG. 6A). And in this original state,
For the game ball B that is going to return from the inside of the game area A toward the runway 6, the blocking piece 20 has a ball B with elastic deformation.
And it is possible to suitably prevent the reversion (see FIG. 6B).

As described above, the ball return preventing device 11 of this embodiment is used.
Can be set at a required position within the range of the set portion 4 of the guide rail 1 so as to prevent the passing of game balls and the return of the game balls, and for each of various game contents set in various types of gaming machines. In the game board P, the ball return preventing tool 11 can be locked and set at each step position of the setting section 4. That is, as a specific example of the installation mode of the ball return preventing tool 11, when the above-described position shown in FIGS. 2 and 3 is taken as the middle position, the upper position shown in FIGS. 6 (a) and 6 (b), FIG. 7 (a) and FIG. 7 (b). Then, under desired execution conditions according to the game content of the game board P or the like, it is possible to perform a suitable passage guide for the game ball B and prevention of reversion by utilizing the elastic deformation of the blocking piece 20.

In the same game board P, it is of course possible to change and set the ball return preventing tool 11 to each step position.

Incidentally, as an example of an installation condition of the ball return preventing device 11 in the game board P capable of developing the respective game contents,
In the case where the desired target area of the game ball B to be driven into the game area A is viewed, if it is desired to drive the ball mainly in the range of the upper central portion in the area A and the upper left and right ends thereof, FIG. If it is desirable to drive the device toward the middle position shown in FIG. 3 and mainly toward the upper end near the left side in the region A, the lower position shown in FIG. 7A and FIG. If it is desired to drive the upper end closer to the right side of the inside, the locking position can be set at the upper position shown in FIGS. 6 (a) and 6 (b), respectively. It can be performed at a desired position.

In the above-described state of operation of the ball return preventing tool 11 at each step position, the step caused by the outer holding piece 13 of the holding section 12 being located on the outer surface of the set section 4 of the inner rail section 3 is the same. Since it is about the thickness (0.1 mm) of the holding piece 13 itself, the step does not substantially become an obstacle to the ball. Therefore, even if the game ball B flying in the flight path 6 comes into contact with this step, the flying power of the ball is not attenuated and the flying state is not adversely affected.

[0024]
