Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball game machine such as a pachinko machine, and more specifically, to a direct or indirect function based on an output of a winning ball sensor for detecting the passage of a game ball through a winning port. The present invention relates to a ball game machine capable of detecting and preventing improper operation of a ball game machine adapted to operate an object.

[0002]

2. Description of the Related Art Conventionally, in a prize winning device of a pachinko machine, a game ball passing through a prize port of a prize device or a starting prize port (including a starting gate and a chucker) is used by using a sensor such as an electromagnetic-sensitive proximity sensor. Various winning objects (electric tulips, electrically powered accessories, etc.) are activated by the output of the winning ball sensor, and a certain number of prize balls are paid out corresponding to the detected winning balls.

Recently, a variable symbol display means, which is also a special accessory, is operated, and when a symbol is displayed in a specific mode,
Pachinko machines that open jackpots for jackpots are widely used. In this case, when a winning ball is detected at a specific starting winning opening, the variable symbol display device is activated in response to the detection signal, and if the symbol when the variation is stopped is a predetermined combination, Output a signal to open the big winning opening, for example,
Activate the electromagnetic solenoid to open and close the special winning opening door connected to the solenoid.

[0004] In this manner, many prize balls are paid out by directly or indirectly operating the accessory based on the detection signal of the prize ball sensor. In such a case, fraudulent acts of fraudulently collecting the premium balls can be performed. Generally, the winning ball sensor is often used as an electromagnetically responsive sensor that detects a change in an electrical physical quantity accompanying the proximity of a game ball and converts it into an electric signal, so that a radio wave that induces the output of each winning ball sensor is used. The so-called radio waves that intentionally transmit and induce erroneous payout of prize balls, or cause various electric accessories to malfunction and generate a large amount of prize balls and deceive many prize balls. Done. Various countermeasures have been conventionally proposed as a countermeasure against the radio wave.

[0005] For example, a method of detecting an improper radio wave to prevent a malfunction or issue an alarm (Japanese Patent Application Laid-Open No. 7-39635, Japanese Patent Application Laid-Open No. 8-155115, etc.) Install a fraud detection sensor that is not affected by the passing of game balls, and take a defensive action when this fraud detection sensor is activated (Japanese Patent Publication No. 7-44967,
No. 86344) has been proposed.

[0006] However, the method of detecting an illegal radio wave requires a complicated radio wave detection device, and the method of providing a fraud detection sensor requires the provision of a fraud detection sensor and a detection circuit separately from the winning ball sensor. The equipment becomes complicated and expensive.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a ball-and-ball game machine capable of reliably detecting and preventing improper use of a radio wave with a simple mechanism and device. is there.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on its embodiments.

FIG. 1 is a diagram schematically showing a game board of a pachinko machine according to an embodiment of the present invention, and is a rear view of the game board. FIG. 2 is a schematic block diagram of a control device of the game board. In FIG. 1, a symbol display device 11 is provided at the center of the game board 10, and a top display member 12
(Usually including the symbol display). A pair of windmill members 13a and 13b are mounted on both left and right sides of the symbol display device 11.

Below the symbol display device 11, in the center of the board,
A tulip-type accessory 21 that is an electric accessory and also serves as a starting winning opening is disposed, and two pairs of general winning openings 22a, 22b, 23a, and 23b are provided on both left and right sides and up and down. A large winning opening 24 having an opening / closing door (not shown) is formed in the center of the bottom of the panel, and a starting gate 25 is located diagonally above the opening.
Branched tubular winning ball passages 20 are connected to the winning ports of each of the aforesaid items, and the winning balls (shown by small circles) from each of the winning ports are collectively carried out.

The windmill members 13a and 13b, the tulip-type accessory 21, the general winning openings 22a, 22b, 23a and 23b, and the special winning opening 24 are provided with the respective mounting bases 10a, 10b and 10 in which the illuminated member is built.
It is attached to the game board 10 by c, 10d, 10e and 10f.

The winning ball sensors 31, 32a, 32b, and 33, which are electromagnetic-sensitive proximity sensors, correspond to the winning holes of each of the above-mentioned characters.
a, 33b, 34, 35 are provided. When the movable piece (corresponding to a petal) is not open, a single winning port is formed in the center of the tulip-type accessory 21.If necessary, the central winning port is also provided. Winning ball sensor
31a is to be attached.

In the pachinko machine of this embodiment, first, when the game ball passes through the starting gate 25, the top display member
Ordinary symbols are variably displayed on 12, and when the winner is won, the movable piece of the tulip-type accessory 21 is opened. Therefore, starting gate 25
Is usually the starting point for the design. On the other hand, when a game ball enters the tulip-type accessory 21, the symbol display device 11 is activated, and the special symbol is variably displayed. When the symbol stops at a predetermined combination of symbols, a big hit occurs, the opening and closing door of the special winning opening 24 opens, and many game balls are guided to the winning opening. Therefore, the tulip-type bonus item 21 is a special winning start opening.

Such control of the game operation is performed by a control device as shown in FIG. FIG. 2 is a block diagram of a simplified control device. The control device 40 has a microcomputer (CPU) 41 as a control center. The CPU 41 is connected to an external ROM 42 and an external RAM 43, and is program-controlled. The CPU 41 is also connected to a clock generation circuit 43, a frequency divider 44 for dividing the frequency of the pulse of the clock generation circuit 43, a reset signal generation circuit 45 of the clock generation circuit 43, and a power supply circuit 46.

Outputs from various sensors are input to the CPU 41 via a signal processing circuit. The CPU 41 drives various electric devices 48 such as solenoids and lamps via a driver 47, and also outputs a voice synthesizing device (SSG). ) 49, an audio signal is output to the speaker 50. Such a control device can be configured by a known control technique.

In the control device of the present invention, the winning ball sensors 31, 32a, 32b, 33a, 33b, 34, 35 are input to the CPU 41 via the respective signal processing circuits 51,
When the sensors 31, 32a, 32b, 33a, 33b, 34, and 35 simultaneously output a false detection signal, a fraud detection signal is issued by the fraud determination circuit 52 (fraud determination means) Turns on the lamp and emits an audible alarm through SSG49
Or from 50.

In some cases, the operating means such as the launching device of the pachinko machine is locked under the control of the CPU 41,
It is also possible to put the apparatus in a non-operation state or stop the operation of paying out premium balls. Such a pachinko machine control technique can be implemented by appropriately employing a known technique.

In the above embodiment, the outputs of all the winning ball sensors are input to the fraud determination circuit 52. However, usually, the number of game balls of a pachinko machine is determined to be within 100 balls per minute, so the number of game balls simultaneously present on the game board is at most 4 to 5 balls, and in normal games, Since it is practically impossible for three or more game balls to win simultaneously, it is considered sufficient to connect three or more winning ball sensors to the fraud determination circuit. In this case, it is desirable to preferentially input a winning ball sensor of each starting winning opening, which is likely to be a target of misconduct.

In the above description, the electromagnetic sensor type proximity sensor has been described as the winning ball sensor. The present invention is applicable not only to this type of sensor but also to other types of winning ball sensors. Speaking of the sensor mounting position, the sensor is installed near the winning opening. However, the sensor may be installed in a conduit of the winning ball passage 20 before the converging point from each winning opening. Also, the pachinko machine has been described as an example of a ball game machine having a prize ball sensor, but it is apparent that the technology of the present invention can be applied to other ball game machines having a prize ball sensor.

[0022]

According to the present invention, a plurality of winning ball sensors output simultaneously in a ball game machine which activates an accessory by the output of a winning ball sensor for detecting the passing of a game ball through a winning port. Since the injustice judging means for judging the injustice is provided to detect the injustice, the injustice can be reliably detected and prevented with a simple device. In addition, existing machines can be easily remodeled, and therefore have high practical value.
