Description

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 winning device for changing the state of a pachinko ball into a state in which it is easy to win a prize on the condition that a preset combination or the like is satisfied.

[0002]

2. Description of the Related Art As a winning device used in the above-mentioned pachinko machine, for example, a variable display device for continuously changing three sets of numbers and patterns, and a number of the variable display device is "7,
There is a combination of a movable winning device that changes to a state in which it is easy to win a prize on the condition that the vehicle is stopped in a preset combination such as "7, 7" or "3, 3, 3. by the way,
If you can change the probability that the numbers on the variable display device are aligned, for example, in several steps, you can change the game board after closing the store, or you can adjust the exit rate of the pachinko machine without adjusting the nails. become. Therefore, a concept of installing such an adjustment switch for changing the probability in a pachinko machine is currently in progress.

[0003]

If the adjustment switch is attached to the outer frame or mechanism plate of the pachinko machine, the compatibility of the game board is lost, and the advantage of making the game board detachable is sufficient. There is a risk that it will not be utilized in the future. That is, the pachinko machine can renew the game content by replacing the game board, but the game board provided with the winning device that does not correspond to the adjustment switch is fitted to the pachinko machine to which the adjustment switch is attached. Then, the adjustment switch is not used at all and is wasted, and conversely, it is impossible to attach a game board provided with a winning device corresponding to the adjustment switch to a pachinko machine not provided with the adjustment switch.

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

[0005]

The present invention has been made to solve the above-mentioned problems, and a winning device in which a pachinko ball changes to a state in which it is easy to win a prize on condition that a combination of preset numbers and the like is established. And a game board or parts integrated with the game board, and an adjustment switch for arbitrarily changing the probability that the winning device will change to a state in which it is easy to win, and only when a specific key is used The present invention provides a pachinko machine provided with a lock means that enables a change operation of the adjustment switch.

[0006]

Since the adjustment switch is attached to the game board or a component integrated with the game board, the winning device and the adjustment switch are integrated via the game board. Therefore, it is possible to fit and use the game board equipped with the winning device corresponding to the adjustment switch for any pachinko machine. Further, since the lock means that enables the operation of the adjustment switch only when a specific key is used is provided, for example, the probability of the prize winning device cannot be changed except by the person in charge of the amusement hall. It is possible to prevent illegal stochastic operations by employees.

The mechanism plate 5 is overlapped with the back surface of the game plate 4 and is hinged to the inner frame 2 so that the game plate 4 can be opened and closed.

As shown in FIG. 2, the front frame 3 has, on its front surface, an openable / closable glass door frame 6 for covering the game plate 4, and an openable / closable front plate 7 for covering the launching portion of the launch rail. An operation handle 8 for adjusting the hitting force of a launch ball, a lower ball plate 10 for receiving an overflow ball from an upper ball plate 9 provided on the front plate 7, and the like are provided.

On the front surface of the game board 4, a circular game portion 4a surrounded by a guide rail 11 is formed. In the game section 4a, a variable display device 12a for continuously displaying numbers "0" to "9" and two or three types of figures on three display sections a, b, c, and the variable display. Starting winning opening 12b for starting continuous display of device 12a, and variable display device 12
For example, when a is stopped by a combination of "7, 7, 7", the opening / closing plate 12c is opened and the movable prize winning device 12d that changes to a prize winning state (special prize game state) is installed. .. In addition, the game section 4a is provided with a normal winning opening 13 for accepting winning balls, an out-ball opening 14 for discharging out-balls, an obstacle nail 15 and a windmill 16 for changing the flow direction of the pachinko ball. Further, a corner ornament 17 is fixed to the front surface of the game board 4 and outside the game portion 4a. On the other hand, as shown in FIG. 1, on the back surface of the game board 4, a prize ball collecting cover 18 for collecting the prized pachinko balls is fixed, and further, the game control for controlling the game contents on the prize ball collecting cover 18. A device 19 is attached.

The mechanism plate 5 is provided with the winning ball collecting cover 18
There is a winning ball gathering gutter 20 that collects the pachinko balls that flow out from. Although not shown in the figure, the mechanism plate 5 has a winning ball processing device that communicates with the end of the winning ball collecting trough 20 to process the winning balls, and a predetermined number of prize balls (for example, a prize ball processing device that works in conjunction with the winning ball processing device). A prize ball discharging device or the like for discharging 15 pieces) is provided.

The pachinko machine P of the present invention includes the prize winning device 1
The adjustment switch 2 for switching the probability that the variable display devices 12a of No. 2 are aligned at "7, 7, 7" into, for example, three levels of high, medium, and low
1 is provided. The adjustment switch 21 is a rotary select switch, and as shown in FIG. 1, the game control device 19
Is electrically connected to. This adjustment switch 21
As shown in FIG. 3, while inserting the switch body 21a into the through hole 22 of the game board 4, the flange-shaped mounting base 21
B is fixed to the game board 4 with screws, and the adjustment knob 2
1 c is projected inside the corner decoration 17.
The corner decoration 17 is provided with a lid plate 23 that can be opened and closed corresponding to the adjustment knob 21c.
The adjustment switch 21 is hidden by setting 3. Thus,
Locking means K that enables the adjustment switch 21 to be operated only when a specific key is used is incorporated in the adjustment knob 21c. That is, the adjusting knob 21c is composed of a pin tumbler lock or a cylinder lock, and the adjusting knob 21c can be operated only by a specific key like the ignition key of an automobile. The locking means K described here
Is physically incorporated in the adjusting knob 21c, but the locking means K may be arranged next to the adjusting knob 21c, for example. Then, according to the probability that the adjustment knob 21c is desired to be set, the probability is read into the game control device 19 by inserting a key into the lock means K.

Next, in the pachinko machine P of the present invention, an adjusting method for changing the probability of the winning device 12 will be described. First, open the glass door frame 6 with a dedicated key for pachinko machines. Since the cover plate 23 of the corner decoration 17 is not particularly locked, it can be easily opened with a finger if the glass door frame 6 is no longer pressed by the glass 6a. Then, a specific key is inserted into the key hole of the adjusting knob 21c and turned to change the probability of the winning device 12. The adjustment switch 21
Is "1, 2, 3" indicating the probability of the variable display device 12a.
Marks indicating three levels of probabilities such as "L, M, H" are provided on a fixed portion such as the mounting base 21b so that the present probability of the winning device 12 can be read in the direction of the keyhole.

When the probability adjustment of the winning device 12 is completed as described above, the cover plate 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 contacts the glass 6a of the glass door frame 6, the glass door frame 6 cannot be closed unless the cover plate 23 is closed. Therefore, it is not forgotten to close the lid plate 23. Further, since the lid plate 23 is pressed by the glass 6a, there is no fear that it will be opened during the game. Therefore, the probability of the winning device 12 is not visible to the player.

[0014]

[Embodiment B] FIG. 4 is a sectional view of a pachinko machine showing an essential part of the 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 the central shaft 24 of the pin tumbler lock, and the engaging claw 25 is engaged with the metal plate 26 on the game board 4 side. is there. On the other hand, the adjustment knob 21c of the adjustment switch 21
Uses normal finger-operated picks.

In the probability changing operation of the embodiment B, first, a specific key is inserted into the key hole of the lock means K, the central shaft 24 is rotated by using the key, and the engaging claw 25 is rotated. The engagement between the dowel 25 and the metal plate 26 is released. As a result, the lid plate 23 is opened, and the inside adjustment knob 21c is operated with a finger.
Then, after the adjustment of the probability is completed, the cover plate 23 is returned to the original position, the engaging claw 25 and the metal plate 26 are engaged, and then the key is removed. In this embodiment B, since the lid plate 23 cannot be opened without a specific key, the advantage that the probability of the winning device 12 is not known to employees other than the person in charge or players who have a matching key for a pachinko machine. There is.

Although the embodiments A and B of the present invention have been described above, the present invention is of course not limited to the above embodiments. For example, in Example A, a lock means having a keyhole shape of a regular polygon or the like whose probability cannot be read is used,
Alternatively, the set value is "1" for each operation of turning the key back.
The cover plate 23 for blindfolding is not necessary if the setting is such that “→ 2 → 3 → 1”. In this way, the locking means K
If the configuration is such that the set value of the probability cannot be read from, it becomes difficult to regularly change the probability.
Therefore, for example, two segment indicators or light emitting diodes are attached, and the former turns on the segment indicator at the same time when the key is inserted to digitally display the rank of probability.
In the latter case, the rank of three stages may be expressed by the combination of ON / OFF of two light emitting diodes. Further, without separately providing such display means, the display portions a, b, c of the variable display device 12a, or a display segment of the number of winning prizes usually provided in association with the variable display device 12a, You may use the segment etc. for a display of the number of times of operation of the movable winning device 12d. Also, in Example B,
The adjustment switch 21 may be any switch such as a dip switch.

In the embodiments A and B, the position of the adjustment switch 21 is, for example, in the game section 4a, on the back side of the game board 4, the game control device 19, or the variable display device 12a.
It may be attached to any place that can be handled integrally with the game board 4, such as to be attached to the movable winning device 12d. In addition,
The component integrated with the game board in the present invention is used in a broad sense, and even when the game control device 19 is provided on the mechanism plate 5, the game control device 19 is a component integrated with the game plate 4. included. Therefore, the game control device 19 provided on the mechanism plate 5 may be provided with the adjustment switch 21. Further, 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. For example, if you win the start winning hole, the opening / closing piece will be 1 or 2.
Even in a so-called airplane-type winning device in which a pachinko ball that enters between the opening and closing pieces at that time changes into a special prize game state when it wins a V pocket, at present, an opening and closing piece is provided at the start winning opening and two pieces are provided. There is also a device in which the opening / closing piece of the starting winning opening is opened for a certain period of time by establishing the combination of the numbers of the 7-segment LEDs, so the present invention can be applied to the case where the probability that the 7-segment LEDs are aligned is adjusted.

[0018]

As described above, according to the present invention, since the adjusting switch is attached to the game board or a component integrated with the game board, the winning device and the adjusting switch are integrated via the game board. Therefore, it is possible to fit and use the game board equipped with the winning device corresponding to the adjustment switch for any pachinko machine.
Further, since a lock means is provided that enables the adjustment switch to be operated only when directly operated by using a specific key, for example, other persons except the person in charge of the game hall change the probability of the winning device. Therefore, it is possible to prevent an illegal stochastic operation by a player or an employee and a stochastic operation by a remote control. In addition, Example A,
When the adjustment knob of the adjustment switch is provided on the front side of the game board as in B, since the probability changing operation can be performed while adjusting the nails, compared to the case where the adjustment knob of the adjustment switch is provided on the back side of the game board, The workability is significantly improved.
