Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inexpensive device management data communication device for outputting management data input from a control circuit of a target device to an external read / write unit by short-range wireless communication, and particularly to a pachinko machine, pachislot machine or the like. The present invention relates to a device management data communication device used in a gaming machine monitoring system for preventing fraud in a gaming machine.

[0002]

2. Description of the Related Art At a gaming facility such as a pachinko hall that provides amusement with a large number of gaming machines such as pachinko and pachislot, a so-called goto act of illegally stealing balls or coins is widespread. Goto acts are sometimes carried out by involving employees of the amusement facility, and by attaching a bypass circuit to the wiring of the control device installed in the game machine, the control operation is disturbed and the control parameter ROM is exchanged to get out. By changing the probability, there are many cases where the number of coins or coins that greatly exceed the number of coins planned for a game machine is acquired. Heretofore, it has been difficult to prevent fraudulent acts on these gaming machines.

However, if there is an illegal act of stealing balls or coins, the operating time information of each gaming machine and the number of jackpots appear abnormal. If the ROM is replaced, it can be detected by checking the ID of the ROM or checking the ROM. In addition, in order to work on the control device, it is necessary to open the lid of the gaming machine and to tamper with the control circuit, so it is necessary to record the door opening and closing history etc. Can detect fraud. However, since these managements are performed by accessing the control board of the gaming machine, the management is performed by opening the lid of the gaming machine after the end of the work, and it is not possible to inspect in real time while the customer is playing.

In Japanese Unexamined Patent Publication No. 2000-24269, the serial number of the game machine, the substrate number of the controller board, the serial number of the ROM, and the like are bar-coded and attached.
An information management method for a gaming machine, in which a bar code reader is used for reading and checking by comparing with a management ledger to check whether major parts incorporated in one gaming machine have been changed. Is disclosed. According to the disclosed method of the present invention, since it can be mechanically read by a bar code reader, there is no misreading or entry error as compared with the naked eye inspection, and accurate management can be performed. Although the disclosed method is a non-contact method of reading information, it is necessary to open the lid of the game machine to handle the parts inside, and therefore the confirmation work cannot be performed while the customer is playing. Moreover, since only items determined at the time of shipment are subject to inspection, it is not possible to collect information on changing conditions such as opening and closing of the lid and the state of balls thrown out due to fraudulent acts.

Further, in Japanese Patent Laid-Open No. 2000-222530,
An IC tag counter is disclosed in which an integrated value of the number of times a game machine, a vending machine, or the like is used is stored and the integrated value is read when an external terminal is brought closer. In this disclosed device, the external terminal can read the integrated value stored in the EEPROM through the non-contact communication means and reset the integrated value to prepare for a new counting. By using this device, it is possible to prevent artificial tampering of the number of times of use, and to prevent fraudulent acts of the clerk such as dressing up the usage amount. However, since the disclosed device is a counter, it is not possible to record or notify the history of events merely by notifying the accumulated value of times, and thus it is not possible to widely deal with fraudulent acts having various forms.

[0006] It should be noted that if the game machine manager is allowed to freely operate and operate the game machine, there is a risk that it will become a gambling machine instead of an appropriate entertainment device. Therefore, an inspection by a fair institution must be made to comply with appropriate regulations. In addition, the circuit configuration is obligatory from the outside so that the operation that affects the probability control beyond a certain range cannot be performed from the outside so that the game room side cannot be unjustly modified. Therefore, it is necessary to prevent the game machine from being attached to a device that affects the circuit from the outside.

On the other hand, the inventors of the present application attach a wireless communication device to the game machine and transmit a large number of information that can be used for fraud detection to the read / write unit by non-contact communication means. We have developed a monitoring system that can easily manage the machine base. However, since such a monitoring system needs to be attached to each of a large number of gaming machines, it is difficult to put it into practical use unless it can be provided as cheaply as possible.

[0008]

The device management data communication apparatus of the present invention senses a data read request when the read / write unit is brought close to the device management data communication apparatus part of the device, and the information collected by then and stored in the storage device. Is read and transmitted by wireless communication, and the read / write unit acquires the information and displays it on the read / write unit or further sends it to the management computer in the control room for display, thereby making it illegal based on the management information for each machine. You can infer the presence or absence of actions. Further, since the communication between the device management data communication device and the read / write unit is performed wirelessly,
Even when targeting a gaming machine, it is not necessary to open the lid of the gaming machine to acquire data, and even when the customer is playing, it is possible to acquire the data without disturbing the play, so during business hours Real-time information can be obtained and managed.

When a large number of target devices are installed adjacent to each other, wireless communication is performed using a non-contact IC in order to avoid interference with electromagnetic waves generated from the devices adjacent to the target device. It is preferable to use weak electromagnetic waves such as those used for cards.

Further, as the RF interface circuit, a non-contact signal transmission function circuit formed in an IC chip of a non-contact IC card which is being used in large quantities can be used. The non-contact IC card has an antenna function and R inside.

Further, the microcomputer chip has a CPU, a coprocessor, a memory, and the like.

Since the RF interface circuit of the device management data communication apparatus of the present invention is a circuit for transmitting a signal from the antenna, it is possible to use the output signal processing function of the non-contact signal transmission function mounted on the RF chip. it can.
Further, the digital signal processing circuit and the storage device in the present invention can be used by incorporating an appropriate IC chip, but the digital signal processing circuit can use the CPU function of the microcomputer chip used for the non-contact IC card, The memory device can utilize the memory function of the microcomputer chip. Since the non-contact IC card is mass-produced and is overwhelmingly inexpensive as compared with a normal device, the IC chip that is necessarily incorporated inside is provided at an extremely low cost. Moreover, the IC chip technology has been sufficiently polished, and its reliability is extremely high. Therefore, by using this IC chip, the device management data communication device can be constructed with high reliability and at extremely low cost.

The storage device uses a memory chip arranged on the control circuit of the device, instead of using the memory function of the microcomputer chip, and directly fetches data from the storage device on the control circuit as needed. You may make it output it. By arranging the storage device on the device, a large amount of information can be freely handled without being restricted by the capacity as compared with the case of using the storage device provided on the IC chip.

FIG. 1 is a block diagram showing a device management data communication device of this embodiment, FIG. 2 is a block diagram of a device management data communication device of this embodiment configured by diverting an IC chip used for a non-contact IC card, and FIG. FIG. 4 is a block diagram showing a non-contact signal transmission function configuration example of an IC chip used in this embodiment, and FIG. 4 is a perspective view showing a usage pattern of the IC chip in this embodiment.

The memory 12 is composed of a ROM and an EEPROM for storing control programs and parameters, and a RAM for temporarily storing management information at a predetermined address. The data stored in the memory 12 includes the number of jackpots, the device operating time, the door opening / closing history of the gaming machine, the unique information of the ROM such as the ID number used, and other logs relating to security. It should be noted that the transmission unit 2 is not provided with a memory for storing data, and the I / O interface 13
The information signal may be directly transmitted / received to / from the control board 3 via. In this case, I / O interface 13
An information signal is supplied from the control board 3.

The RF interface 14 is a memory 12
The digital information signal flowing out of the antenna is converted into an analog signal, the carrier signal flowing through the antenna 15 is modulated, the information signal is put on the signal, and the read / write unit 4 reads it.
Used for managing gaming machines. The read / write unit 4 includes an antenna, and exchanges electromagnetic waves with the antenna 15. Since the read / write unit 4 receives the information signal by holding it over a predetermined position of the gaming machine 1,

For example, it is possible to detect that the ROM has been illegally replaced by confirming that the checksum value of the ROM has changed.

Since the game machines of the same type are often arranged very close to each other in the game arcade, it is important not to be confused with the information of other machines, and the multi-channel selection method is used. There are also methods, but more simply, contact type non-contact communication that performs communication of several mm using weak radio waves, proximity non-contact communication that performs communication of several cm, or communication of several tens of cm. It is preferable to use proximity contactless communication for performing. If such a communication system is used, even if the same circuit is mounted on a large number of gaming machines and one carrier is shared and information is collected by one read / write unit, it will be The information can be collected accurately without being mixed.

The reset signal generation function supplies the power to the microcomputer circuit after confirming that the power received by the antenna function has exceeded the specified value, and also specifies the timing required to reliably perform non-contact communication. It is a function to output to. Therefore, with a slight modification, the reference wave generated in the read / write unit 4 can be used to detect and notify the microcomputer circuit. The I / O interface 13 is
The contactless IC card does not have the same function because it has a function of exchanging information signals with the input / output terminals of the control board 3 of the machine base. However, by connecting the I / O interface 13 to the data bus in the contactless IC card,
