SUMMARY OF THE INVENTION The present invention comprises a plurality of symbol display portions for variably displaying various predetermined symbols, and detects a ball when a game ball passes a starting gate provided with a ball detection device. Each symbol display unit starts to fluctuate based on the ball detection signal from the device, stops and displays various combinations of symbols, and in the case of a specific symbol, a symbol combination display that provides a predetermined profit to the player In a pachinko machine having a device and a probability setting means capable of changing a hit probability combined with the specific symbol, the first means is provided on a pachinko machine surface that is visible to a player when a designated probability value is changed and set. A probability change display device for displaying a set value for a certain period of time is provided.

The second means uses the display device, wherein the probability setting means comprises the same number of probability designation contacts corresponding to a plurality of designated probability values, and a common contact connected to one of the designated contacts. And a probability setting switch comprising a manual slider, and an electromagnetic lock device for preventing operation of the manual slider is provided, and the electromagnetic lock device is driven by the same power supply as the probability change display device. It is characterized by the following.

A third means is that pachinko games are stopped.
If the predetermined time has not elapsed, a change command of the hit probability value is issued.
It is characterized by having lock means for preventing it from being accepted .

[0007]

When the game ball passes the starting gate, the symbol combination display device is driven to start and stop each symbol, and displays various combinations of symbols. When the symbol becomes a predetermined combination of symbols such as the same symbol, a large gain ("hit") is given to the player by opening a special winning opening or the like.

[0008] By the way, in the apparatus provided with means for changing the probability of the hit state, like the first means, the change of the probability of displaying the set value on the pachinko machine surface visible to the player for a certain period of time If the display device is provided, if the probability setting is changed during the game, such a fact will be displayed for a certain period of time, and the player will know the change in the probability. Therefore, the setting of the game hall cannot be changed at least until the pachinko game ends, and the profit of the player is maintained. In addition, the display contents of this probability change display device can directly display the change probability, or “change probability”.
Various modes can be proposed, such as a cautionary display such as.

On the other hand, when the designated probability value is stored in the internal storage device RAM connected to the central control unit CPU, the set designated probability value is erased by turning off the power after closing a store or the like.
You have to reset it. Therefore, the probability setting switch may be constituted by a probability setting switch including the same number of probability designation contacts corresponding to a plurality of designated probability values and a manual slider having a common contact connected to any of the designated contacts. Conceivable. However, when the data is stored and held by the manual probability setting switch, as described above,
Even with a probability change display device that displays the designated probability value changed on the pachinko machine surface for a certain period of time, turning off the power pretending to be a failure, disabling the first means described above, operating the probability setting switch, and By re-administering the power, the designated probability value can be changed without the player noticing. Therefore, in the second means, the probability setting switch cannot be operated unless the lock is released by electrically activating the electromagnetic lock device. For this reason, in the state where the power is turned off as described above, the electromagnetic lock device does not operate, and thus the specified probability value cannot be changed by the above-described method. Therefore, the first means is more effective. It is possible to do.

Furthermore, in the third means, the probability setting cannot be changed by the lock mechanism unless a predetermined time has elapsed after the pachinko game has been stopped . Therefore, as long as the player continues to play the game, the probability is not changed by the operation of the game hall.

The symbol display device 19 indicates a numerical value related to a required gain in relation to the symbol gate 18, and has a function as a probability change display device for displaying a designated probability value for a certain period of time as described later. You may do it.

The starting gate 14 and the symbol gate 18 also serve as a winning port, and a predetermined number of prize balls are provided as the game balls pass.

Further, below the winning opening opening / closing device 15, a winning device 10 having a wide large winning opening 11 is provided. The winning device 10 has a known structure in which the lid 12 is opened in the front-rear direction by a solenoid to guide a game ball to the special winning opening 11 by a guiding action of the lid 12. When a game ball enters a specific area in the center, a continuous opening operation is performed.

Next, the operation of the above configuration will be described. When a game ball passes through the starting gates 13, 13, and 14,
The combination display device 6 is driven together with the supply of the prize ball.
When passing continuously, the standby recording lamps arranged on both sides of the symbol display device 19 are sequentially turned on and held up to four times.

When the combination display device 6 is driven,
The symbol display units 7a, 7b, 7c start to fluctuate, and after about 8 seconds elapse, the fluctuation of the symbol display units 7a, 7b, 7c stops in this order. The symbol display sections 7a, 7b, 7c are, for example, "1,1,1", "2,2,2", "3,3,3",
When the symbols, such as "4,4,4" and "A, A, A", have the same symbol or numeral, it becomes a "big hit" and the notification device emits a sound and the prize device 1
The solenoid 0 is driven, the lid 12 is tilted forward, and the special winning opening 11 is opened. The special winning opening 11 is continuously driven when passing through the specific area, and after the opening operation is completed, the special winning opening 11 is opened again.

Also, "2,2, X", "4,4, X",
A combination of “6, 6, X” (X is a variable) or the like may be a small hit in which the special winning opening 11 is opened for a short time and a small number of times.

The above series of operations is performed by the central control unit CPU.
(See FIG. 2).

Next, the main part of the present invention will be described. FIG.
As shown in the figure, a probability change display device 20 is provided at the upper right of the pachinko machine 1. As the display contents of the probability change display device 20, various modes can be proposed, such as directly displaying the change probability and displaying a warning such as "probability changing". Then, the probability change display device 20 is displayed in synchronization with the designation input of the designated probability value to the central control unit CPU by the probability setting switch 23 and the like as described later. You may do it.

In addition, instead of the probability change display device 20, a symbol display device 19 provided immediately below the symbol gate 18,
The symbol display units 7a, 7b, 7c may be used as a probability change display device.

FIG. 2 shows an electric control unit. An input / output circuit 40 is connected to the central control unit CPU, and a combination display device 6, a probability change display device 20, and a pilot lamp connected to the input / output circuit 40. 21 and the solenoid 22 are controlled by the central control unit CPU. Similarly, signals from the probability setting switch 23, the capture key switch 42, and the like connected to the contact input / output circuit 41 are input. The central control unit CPU has a storage device RAM,
ROM is connected.

The probability setting switch 23 constitutes a probability setting means for setting the probability that the symbol display sections 7a, 7b, 7c of the combination display device 6 will be in the "hit" state as described above. It is possible to change the specified probability value in several steps such as 200, 1/220, 1/240, etc. In order to make the probability setting switch 23 effective, the capture key switch 42
Probability management is enabled by making the ON operation of a condition a condition. An example is shown in FIG.

An example of the probability setting switch 23 is shown in FIG. Here, reference numeral 24 denotes a rotary type manual slide, which is rotatable by a knob 25, and a probability designation contact 28a in which a common terminal 27 provided at an end of the rotating shaft is fixed around the end. To 28d. The probability designation contacts 28a to 28d correspond to different designated probability values, respectively, and are connected to the common terminal 27 so that a command is input to the central control unit CPU, and the central control unit CPU is connected to the probability designation contacts 28a to 28d. The combination display device 6 is driven so as to have the probability corresponding to the connection position.

With the rotation of the knob 25, the common terminal 27
The designated probability value (or a cautionary display that changes to this) is displayed on the probability change display device 20 for a predetermined time in synchronization with the probability designation contact points 28a to 28d that are newly connected and the probability is changed. . Therefore, during the game, the knob 2
When the player rotates 5, the player will know the change operation based on the content displayed on the probability change display device 20. I have to make changes and adjustments. For this reason, a probability change that gives a profit or a disadvantage only to a specific player is prevented, and an unfair game mode is eliminated. Moreover, since the probability value is set by the manual rotation of the knob 25, the specified probability value is mechanically stored and retained even when the power is turned off, and has reproducibility.

As a switch using a manual slider, a slide switch in a linear direction is used as the probability setting switch 23 in addition to a rotary switch.

In the configuration of the probability setting switch 23 which is mechanically stored and held, the designated probability value can be changed by operating the knob 25 even when the power is turned off. For this reason, as described above, the fact that the pachinko machine surface has been changed is displayed by the probability change display device 20 for a certain period of time, and even if an attempt is made to optimize the game mode, the power is turned off in the form of a failure, and the probability setting switch By turning the knob 25 of 23 and re-administering the power, the designated probability value can be changed without the player noticing. Therefore, in order to prevent this, the knob 25 is provided by the electromagnetic lock device 30.
The rotation is locked.

The structure of the electromagnetic lock device 30 will be described with reference to FIG. A plurality of engagement grooves 31 are formed around the knob 25 at equal angular intervals with the probability specifying contacts 28a to 28d, and a lever 32 pivotally supported by a shaft 33 and rotatable is formed by a spike 35. It is biased to the knob 25 side.
For this reason, the engagement end 34 is fitted into the engagement groove 31 at a position where the common terminal 27 is connected to any of the probability specifying contacts 28a to 28d by the urging force of the ridge 35, and the knob 25 is The rotation is restricted. On the other hand, the electromagnet 36 is located near the side of the lever 32, and by energizing the electromagnet 36, the lever 32 is attracted and the engaging end 34 is moved from the engagement groove 31 against the urging force of the ridge 35. I try to evacuate. Thus, by electrically connecting to the electromagnet 36, only when the electromagnetic lock device 30 is turned on, the rotation operation of the knob 25 can be performed, and the probability can be changed.

As another configuration of the electromagnetic lock device 30, a device using a solenoid for retracting and driving the lever 32 against the ridge 35 can be proposed.

By attaching the electromagnetic lock device 30 to the probability setting switch 23 in this way, when the power is turned off to invalidate the display of the probability change display device 20, the electromagnet 3
6 cannot be energized, so that the probability setting switch 23 cannot be operated. Thus, the above-mentioned work becomes impossible, and the effect of suppressing the improper adjustment operation caused by arranging the probability change display device 20 on the surface of the pachinko machine 1 can be held more effectively.

The above-described configuration is a configuration in which the designated probability value is mechanically stored and held.
A storage device RAM for holding the specified probability value may be connected. However, in such a case, the memory is lost when the power is turned off. Therefore, it is necessary to back up this memory with a battery, a capacitor, or the like, or to use a nonvolatile memory.
Alternatively, the data may be stored using an external magnetic storage device such as a card type.

As another means for storing the data, for example, as shown in FIG.
1 and L2, and controls a relay input / output circuit 45 using a probability setting key switch 46. The state of the latching relays L1 and L2 is controlled by a central control unit CPU via a contact input / output circuit 47. Alternatively, the information may be output. In this case, as shown in FIG. 5, there are four types of on / off combinations of the latching relays L1 and L2 (a to
d), and accordingly, four types of designated probability values can be selected. Thus, the key switch 46 is used to sequentially change the combination in synchronization with the execution of the ON operation, and the designated probability value corresponding to the combination is instructed to the central control unit CPU. Thus, even when the power is turned off, the designated probability value is stored and held because the state values of the latching relays L1 and L2 do not change.

Next, as another probability voluntary change preventing device for preventing a change of an improper designated probability value of a game arcade, there is a snap-in.
If the predetermined time has not elapsed since the game was stopped, the probability value
Lock means to prevent the
As a result, the probability setting can be changed only after a predetermined time has elapsed.
You may make it. As this locking means, on / off information of the operation state of the rotary handle for firing a ball is input to the central control unit CPU, and if a predetermined time has not elapsed from this off state, designation by the probability setting switch 23 is performed. What is necessary is just to program in advance in the central control unit CPU so as not to accept the change command of the probability value.
Thus, the player cannot change the designated probability value unless the game is interrupted, thereby preventing improper change by the game hall.

[0034]

According to the present invention, as described above, the present invention is provided with means for changing the probability of changing the hit state by the combination display device. Is displayed for a certain period of time, the game hall cannot change the settings at least until the pachinko game is over, so that the specified probability value can be changed only at the appropriate time when the game has settled down. Changes can be made, the fairness of the player is maintained, and an appropriate game mode can be maintained.

When the probability setting means uses a probability setting switch capable of selecting a probability by manual operation, the probability setting switch cannot be operated unless the electromagnetic lock device is operated to release the lock. In the configuration described above, it is possible to disable the probability change display device and turn off the probability setting switch after disabling the power in a manner of disguising the failure, and to make it impossible to operate the probability setting switch. It can be even more complete.

[0036] In addition, to stop the pachinko, given
If the time does not elapse, the probability change command will not be accepted
Even if there is a lock means to make it impossible to change the probability setting until a predetermined time has elapsed, it is possible to change the designated probability value only at the appropriate time when the game has settled down Thus, the same effect as described above is obtained.
