DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine equipped with a prize-winning device which changes into a state where a pachinko ball easily wins on condition that requirements such as preset combinations are satisfied.

[0002]

2. Description of the Related Art As a prize winning device used in the above-mentioned pachinko machine, for example, a variable display device for continuously changing three sets of numbers and pictures, and a number of the variable display device being "7,
There is a combination with a movable prize device that changes to a state in which it is easy to win on condition that the vehicle stops at a preset combination such as "7, 7" or "3, 3, 3".

By the way, if it is possible to change the probability that the numbers and the like of the variable display device are aligned in, for example, several steps, it is possible to reduce the pitching rate of pachinko machines without replacing the game board after closing the store or adjusting the nails. It becomes possible to adjust. Therefore, a concept of installing such an adjustment switch for changing the probability in a pachinko machine is currently in progress.

[0004]

If the adjustment switch is mounted on an outer frame, a mechanism plate, or the like of a pachinko machine, the compatibility of the game board is lost, and the merit of making the game board detachable is sufficient. May not be utilized. That is, the pachinko machine can renew the game content by refitting the game board. However, the pachinko machine fitted with the adjustment switch is fitted with a game board provided with a winning device that does not correspond to the adjustment switch. That is, the adjustment switch is not used at all, and it is useless. Conversely, a game board provided with a prize device corresponding to the adjustment switch cannot be attached to a pachinko machine without the adjustment switch.

Further, if the adjustment switch has a structure that can be easily operated by opening the front frame or the glass door frame, the employee may collude with the player to illegally increase the probability of the prize winning device, or the pachinko machine. There is a possibility that a player who has the same key may illegally increase the probability of the variable display device.

The gaming section 4a includes a variable display device 12a for continuously displaying numbers “0” to “9” and a few types of graphics on three display sections a, b, and c one after another; A starting winning port 12b for starting the continuous display of the device 12a;
When a is stopped in a combination of, for example, "7, 7, 7", a prize winning device 12 including a movable prize device 12d that opens and closes the open / close plate 12c and changes to a state in which it is easy to win (special prize game state) is installed. . The gaming section 4a is provided with a normal winning port 13 for receiving a winning ball, an out ball port 14 for discharging an out ball, an obstacle nail 15 for changing the flow direction of a pachinko ball, a windmill 16, and the like. Further, a corner decoration 17 is fixed to the front of the game board 4 and outside the game section 4a. On the other hand, as shown in FIG. 1, a winning ball collecting cover 18 for collecting winning pachinko balls is fixed to the back surface of the game board 4, and a game control for controlling the game content on the winning ball collecting cover 18. A device 19 is mounted.

The mechanism plate 5 has the winning ball collecting cover 18
A prize ball collecting gutter 20 is provided for collecting pachinko balls flowing out of the pool. Although not shown, the mechanism plate 5 communicates with the end of the prize ball collecting trough 20 to process a prize ball, and a fixed number of prize balls (for example, 15) is provided.

In the pachinko machine P of the present invention, the prize winning device 1 is provided.
Adjustment switch 2 that switches the probability that the two variable display devices 12a are aligned at “7, 7, 7” to, for example, three stages of high, medium, and low.
1 is provided. The adjustment switch 21 is a rotary select switch, and as shown in FIG.

When the probability adjustment of the winning device 12 is completed as described above, the cover 23 of the corner decoration 17 is closed and then the glass door frame 6 is closed. Since the cover plate 23 of the corner decoration 17 comes into contact with the glass 6a of the glass door frame 6, the glass door frame 6 does not close unless the cover plate 23 is closed. Therefore, there is no forgetting to close the cover plate 23. Further, since the cover plate 23 is pressed by the glass 6a, there is no possibility that the cover plate 23 will be opened during the game. Therefore, the probability of the winning device 12 is not visible to the player.

[0017]

[Embodiment B] FIG. 4 is a sectional view of a pachinko machine showing a main part of an embodiment B. The locking means K of this embodiment B is provided on the cover plate 23 of the corner decoration 17. That is, the lid plate 23
A pin tumbler lock is fixed to one end of the pin tumbler lock, and an engaging claw 25 is provided on a center shaft 24 of the pin tumbler lock, and the engaging claw 25 is engaged with a metal plate 26 on the game board 4 side. is there. On the other hand, the adjustment knob 21c of the adjustment switch 21
Use a normal knob that can be operated with a finger.

In the probability changing operation of the embodiment B, first, a specific key is inserted into the keyhole of the lock means K, and the center shaft 24 is rotated using the key to rotate the engaging claw 25. The engagement between the dowel 25 and the metal plate 26 is released. As a result, the cover plate 23 is opened, so that the middle adjustment knob 21c is operated with a finger.
Then, after the adjustment of the probability is completed, the cover plate 23 is returned to its original position, and the key is removed after the engagement claw 25 and the metal plate 26 are engaged. The advantage of this embodiment B is that the lid 23 cannot be opened without a specific key, so that the employee other than the responsible person or the player holding the key of the pachinko machine does not know the probability of the winning device 12. There is.

Although the present invention has been described with reference to the embodiments A and B, the present invention is not limited to the above embodiment. For example, in the embodiment A, the shape of the keyhole is set to a regular polygon or the like, and a lock means whose probability cannot be read is used,
Alternatively, the set value is set to “1” for each operation of turning the key back.
If it is set to circulate as "→ 2 → 3 → 1", the cover plate 23 for blindfold is not required. Note that the locking means K
If the configuration is such that the set value of the probability cannot be read from, it becomes difficult to perform the work of changing the probability properly.
Therefore, for example, two segment indicators or light-emitting diodes are attached, and the former displays the probability rank digitally by turning on the segment indicator at the same time as inserting the key,
In the latter, three ranks may be expressed by a combination of ON / OFF of two light emitting diodes. Further, even if such a display means is not separately provided, the display portions a, b, and c of the variable display device 12a or the display segments of the number of prizes usually provided along with the variable display device 12a, A segment or the like for displaying the number of times of operation of the movable winning device 12d may be used. In Example B,
The adjustment switch 21 may be any switch such as a dip switch.

Further, Example A, in B, the position of the adjustment switch 21, for example, in the gaming portion 4a, variable display device 12a, the movable winning device 12d or the like, the game board 4 or the game board
It may be mounted anywhere on the front of the part integral with 4 . In the embodiments A and B, the winning device may be other than the combination of the variable display device and the movable winning device shown in the drawings. For example, when a winning prize is won, the opening / closing piece is changed to 1 or 2
The so-called airplane type prize device which opens and turns into a special prize game state when the pachinko ball inserted between the opening and closing pieces in the V pocket at that time also has an opening and closing piece at the starting prize opening and two Since there is a configuration in which the opening and closing piece of the starting winning opening is opened for a certain period of time when the combination of the numbers of the 7-segment LEDs is established, the present invention can also be applied to a case where the probability that the 7-segment LEDs are aligned is adjusted.

[0021]

As described above, according to the present invention, the adjustment switch is arranged on the front surface of the game board or a part integral with the game board.
The winning device and the adjustment switch are integrated via a game board.
Therefore, any pachinko machine can be used by fitting a game board equipped with a winning device compatible with the adjustment switch. In addition, since a locking means is provided which enables the operation of the adjustment switch only when the key is operated directly by using a specific key, for example, the person other than the person in charge of the game hall changes the probability of the winning device. This makes it possible to prevent a player or an employee from performing an unauthorized probability operation and a probability operation using a remote control. In addition, the game board also
Is an adjustment switch and lock on the front side of the component integrated with the game board.
Since the step is provided, the probability can be changed while performing the nail adjustment. Therefore, workability is remarkably improved as compared with the case where the adjustment knob of the adjustment switch is provided on the back side of the game board.
