DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inspecting a board of a pachinko game machine for unauthorized rewriting of a program (including data in a memory such as a ROM).

[0002]

2. Description of the Related Art Conventionally, as a memory (ROM) for storing programs and data used in a control circuit of a pachinko amusement machine, only a ROM of model No. 2764 is permitted to be used. Replace with something
In some cases, the fraud was changed to change the establishment of the ball.

[0003] Such fraudulent forms include: ROM change type (1) A method of replacing with a 2764 in which an unauthorized program is written. This can be easily detected by reading the contents of the memory using a ROM writer or the like. (2) Use a regular ROM with the appearance of model number 27128 with a large capacity.
Method used to imitate. This allows fraud to be found by using the corresponding memory read function. (3) A circuit is added in 27128 similar in appearance to 2764, and a normal program runs when the power is turned on, but switches to an incorrect program after a lapse of a specific time. (4) A dual-layer ROM that switches to an incorrect program after a check at power-on. The feature is that the ROM core has several layers and is not erased even when irradiated with ultraviolet rays. (5) A four-layer ROM, which switches to an illegal program at a specific address, such as at the time of a big hit, when an attacker opens, and when a V prize is won. 2. CPU type (1) A type in which a surface mount type component is incorporated into an unauthorized CPU, a type molded by a hybrid IC, or an unauthorized CPU using a film type substrate under an authorized CPU.
And a type equipped with a circuit incorporating a ROM and a control circuit.

[0004] A feature is that two pins of the ROM are floating. 3. Socket type As in the case of the CPU type, an illegal circuit is built in using a film type substrate under the ROM socket. The feature is that the pins of the real ROM are floating. 4. IC type An IC around the CPU that has been converted to a microcomputer or has undergone special processing. As mentioned above, there are various illegal boards,
It is impossible to find it by ordinary visual inspection.

[0005] In this kind of illegal ROM board, if the probability of a specific pachinko game machine with a particular pachinko game machine mounted thereon is uniformly increased, the pachinko parlor management computer finds it when the total is counted. The program is designed to increase the establishment only under specific conditions set by the customer (Goto ROM group) and reduce the establishment accordingly to the general customer, so that it will fall within the prescribed establishment on average. Is the feature.

Further, since the execution time of the program is different while the unauthorized program is operating, there are many models that switch to the incorrect program when the power is turned on and have different initial values after the power is turned on.

[0007]

As described above, a maliciously programmed illegal ROM is not only visually inspected but also R
Even with an inspection device such as an OM writer, it could not be easily found. In addition, there is a general-purpose device that checks the operation of the pachinko game machine immediately after turning on the power, but this device can check the single-shot operation after turning on the power, but cannot simulate the jackpot continuously and inspect it. It cannot support the type called ROM.

It is an object of the present invention to provide an inspection apparatus which can easily set each model and can detect various illegal ROMs.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a pachinko game machine according to the present invention. FIG. 1 is a plan view of an illegal board inspection apparatus for a pachinko game machine according to an embodiment of the present invention.

In the figure, K is an illegal board inspection apparatus for pachinko game machines (hereinafter simply referred to as an inspection apparatus), 1 is a detachable storage means for storing inspection data for each model of pachinko game machines, and 2 is a CPU. , A detachable CPU cassette 3 having an operation command input means 31 and an inspection result display means 32, and 4 being connected to the main body 3 via a cable and detachably attached to a board B of a pachinko game machine. Connector.

In FIG. 2 showing the use state of the pachinko game machine illegal board inspection apparatus K of the present invention, first, the power of the pachinko game machine is turned off, and the power plug is connected to the power output outlet of the inspection apparatus K. , The connector B1,
B2 and the connector 4 of the inspection device K are connected.

Thereafter, the power supply of the inspection apparatus K is connected, and the start switch is pressed to start the inspection. When the inspection is started, based on the inspection data fetched from the storage means, the control program built in the CPU cassette inspects whether or not the board B connected to the connector 4 has an illegal portion. The inspection result is displayed on the inspection result display means of the main body. That is, if an error is found on the substrate B, "error" is displayed on the inspection result display means 32, and if no error is found, "OK" is displayed.

As shown in FIG. 3, the inspection apparatus K includes an input circuit 21 for receiving a synchronization signal and a jackpot signal from the board B via the connector 4, and a simulation of a timing unique to the board B based on the synchronization signal. A simulation signal generation circuit 22 for generating a winning signal; and an output circuit 23 for outputting the simulation winning signal to the substrate B, and for detecting a jackpot signal output from the substrate when the simulation winning signal is output. And a control circuit 24.

An example of the control program will be described below. In the case of the substrate B, a certain time (usually called a reset time of about 0.00)
Every one second to 0.004 seconds), the jackpot random number (counter value of the counter) is updated by +1. When it reaches the maximum value, it is cleared and returned to 0. When a simulated winning signal is received from the inspection device K, the count value of the counter is fetched, and if the count value is a predetermined value, it is controlled so as to be a big hit.

Therefore, the inspection apparatus fetches a synchronization signal synchronized with the reset time from the substrate, and generates a simulated winning signal at a timing of a big hit on the inspection target substrate obtained in advance based on this timing. Input to the board. If the program on the board is normal, a jackpot signal is returned in response to the input simulated winning signal.

When the jackpot signal is returned, the target board can be determined to be correct, and if the jackpot signal is not returned, it can be determined that the board is not a correct board.
The synchronization signal may be any signal as long as it can determine the reset state, and need not be an independent synchronization signal.
For example, a configuration may be adopted in which a signal that can determine the reset state is obtained by dividing or multiplying the frequency.

The above description relates to a synchronous inspection apparatus.

In the case of the asynchronous type, the connector is connected to the winning connector on the board and the shoulder lamp connector. And since this asynchronous type is a simple wiring, when a big hit comes out, it is punctured manually. That is, the big hit is repeated by putting 10 or more balls in 10 counts and puncturing. At this time, the judgment is made based on the number of repetitions of the jackpot.

For example, in the case of an unauthorized ROM, it can be determined whether there is no big hit, no second big hit, or no big hit after the probability change.

In the mainstream of pachinko game machines, the jackpot determination random number is updated at each reset, and the "losing pattern" and the "big hit pattern" are updated during the weight loop processing. In the case of an incorrect board, another program is inserted for each reset, so "missing" immediately after turning on the power
In particular, "right picture" and "big hit picture" are different from the original numbers.

By paying attention to this point, an illegal board can be found by comparing the "missing" immediately after the power is turned on, particularly the "right picture" and the "big hit picture" with the original appearance. Also,
It is also possible to detect abnormal operation for a long time while operating the pachinko game machine continuously after the jackpot.

This inspection apparatus is configured to read inspection data for various models from dedicated storage means 1 respectively. If the replacement of the inspection data is not sufficient, the CPU cassette can be replaced. In addition, this device can repeat a jackpot several times, and perform a complete check while simulating actual operations such as right generation processing, attacker processing, and payout.

Depending on the structure of the legitimate substrate or the type of the improper ROM substrate, it is not sufficient to simply check the loss. In particular, in the case of the four-layer ROM type, it is necessary to repeatedly check the processing such as a big hit. On the other hand, according to the inspection apparatus of the present invention, since a process such as a jackpot can be repeatedly generated many times to perform an inspection, an unauthorized program such as a four-layer ROM type which cannot be detected by the conventional inspection apparatus can also be found. It is.

In addition, depending on the type of the right object, the arrangement ball, etc., there are two or more stages of judgment, so that special inspection data is required. Since the substrate is sealed, inspection of the sealed ROM is difficult. However, according to the inspection apparatus of the present invention, since the inspection is performed by exchanging signals via the connector connected to the board, the inspection can be performed only by connecting the connector without opening the case of the target board. .

Further, according to this inspection apparatus, since the jackpot can be inspected not only once after power-on or once after a predetermined time but also many times in succession, it cannot be found conventionally. Now you can even find clever rogue boards.

To take in the inspection data of the new model, insert the storage means and input, for example, "0000" and enter "SE".
When the "T" switch is pressed, the data in the storage means is registered in the memory of the inspection device. Such model-specific inspection data can be registered with an index of 255. In addition, various settings such as a jackpot probability, a reset cycle / counter value, an initial value, a loss value, and the like can be made.

The above operation is shown as a system diagram in FIGS.

In FIG. 8, reference numeral 60 designates an illegal circuit board inspection apparatus for a pachinko game machine according to claim 2, comprising an input circuit 61 for taking in a synchronization signal and a jackpot signal from the pachinko game machine;
A simulation signal generation circuit 62 for generating a simulation winning signal at a timing unique to the pachinko game machine based on the synchronization signal, an output circuit 63 for outputting the simulation winning signal to the board of the pachinko game machine, and a connector for the board of the pachinko game machine A connector 64, which is detachable from the connector and is configured to receive a synchronization signal and a jackpot signal from the board of the pachinko game machine and to output a simulation winning signal to the pachinko game machine, and to output a simulation winning signal. A display unit 65 for displaying a jackpot signal output from the board of the pachinko game machine;
And operates in the synchronous type described above.

This inspection apparatus is a dedicated machine for each model. It should be noted that the timing data in the simulation signal generation circuit 62 can be changed to another model by rewriting the timing data. When inspecting with the inspection apparatus of the present invention, generally, a connector for connecting the board B to be inspected and the main body side is once removed, and the connector from the inspection apparatus is inserted into the board B for use. However, if an illegal circuit is attached to the main body, the illegal operation cannot be found even if the unauthorized circuit is removed from the main body and inspected as described above. It is also necessary to do. For this purpose, the cable connecting the substrate B and the main body may be branched and connected to the present inspection apparatus.

Alternatively, the connector portion of the inspection apparatus may be a pin-type or clip-type terminal.

[0033]

According to the illegal board inspection apparatus for a pachinko game machine according to the first aspect of the present invention, since the storage means for storing the inspection data for each type of the pachinko game machine is detachable, the model is changed. In this case, it is only necessary to replace the storage means, and the inspection can be efficiently performed in the hall where a plurality of models are arranged.

Further, in the case of a special model, the CPU cassette can be replaced to cope with it. According to the inspection apparatus of the second aspect, since it is a dedicated machine set for each model, many identical models can be efficiently inspected in a short time.
