Description

  The present invention relates to an inspection system for a gaming machine, and more particularly to an apparatus using a rewritable RFID.

  A gaming machine such as a slot machine is provided with a slot for a game medium such as a game ball or medal, and a player can enjoy a game by inserting a predetermined number of medals. A medal, which is an example of a game medium necessary for a game, can be borrowed by a medal lending machine provided in a game hall, and a game can be started by inserting it into a medal slot of a desired gaming machine. it can.

The operation of the conventional gaming machine was as follows.
First, when the start switch is operated, the start switch is turned on. In response to this, a lottery process is performed by a winning lottery means inside the gaming machine. Here, when a predetermined combination is won, a winning flag is set. The rotating reel starts to rotate. When the stop switch is operated, the stop switch is turned on. Then, the rotation of the corresponding rotating reel is stopped. After the stop switches corresponding to all the rotating reels are operated, whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed. Is determined. When it is determined that the winning is confirmed, a medal corresponding to the winning symbol is paid out.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). In other words, only when winning in the lottery process, medals are paid out by winning a winning pattern under a predetermined condition, but when not winning, medals are paid out regardless of how the stop switch is operated. There is no. This is to keep the medal payout at a certain probability. In order to realize this, a random number generator is used in the lottery process.

  The gaming machine basically pays out medals when the pattern is complete, but whether the pattern is complete or not depends on the result of a lottery by an internal computer. Various prizes, such as big bonuses, regular bonuses, and small roles, also follow the results of internal computer lottery. The lottery process can be set within a predetermined range, and setting work is performed by the store in a hall or the like where a gaming machine is installed. The setting change was performed by a procedure such as opening a door of the gaming machine, turning on a setting key switch provided in the power supply unit, and performing a predetermined operation such as pressing the setting change switch.

  A small part of the players performed a dishonest act (so-called goto act). For example, there has been a person who illegally changes the setting of the gaming machine to one advantageous for himself by performing the setting operation illegally. The door of the gaming machine is provided with a key so that it cannot be opened and closed easily, and a key is also required for the operation of the setting key switch. It seems that the setting is performed illegally by adding a work to the wiring of the setting key switch using the gap of the housing. In conventional gaming machines, there was no security measure other than the mechanism of the key.

  By the way, in a conventional gaming machine, RFID (Radio Frequency Identification, hereinafter referred to as “RFID”) that enables product information such as an ID code to be recognized in a non-contact manner on an electronic component such as a main board that performs main control relating to gaming. )).

  The RFID is a responder including an integrated circuit (including a storage unit), a wireless circuit, and an antenna. As an interrogator corresponding to this, there is a reading / writing device (hereinafter referred to as “RFID reader / writer”) for reading information from RFID and writing information. This includes a control unit, a radio circuit, and an antenna. As a method for non-contact communication by RFID, electromagnetic coupling type / electromagnetic induction type that uses mutual induction of coils by 13.56 MHz AC magnetic field, and microwave that transmits / receives by 2.45 GHz microwave There is a type.

  A conventional method of using RFID in a gaming machine is to store a certain value of data in the RFID, collate this data with other data, and determine whether both data match. Conventional RFID is read-only, and data cannot be rewritten after product shipment, so it cannot be used to prevent unauthorized actions such as the above-described setting change.

  The present invention is intended to manage a gaming machine using a rewritable RFID. Specifically, the gaming machine is provided with a writing device for writing data to the RFID and the RFID, and responds to internal changes in the control system. The writing device updates the internal information in the RFID, and the updated information is used for reading management without contact. It is an object of the present invention to provide a gaming machine, a gaming machine inspection device, a testing method, and a program capable of determining the presence or absence of the above-described setting change fraud by using a rewritable RFID.

  RFID (Radio Frequency Identification) is a type of electronic tag that has electronic information inside and identifies an object by communicating with a reader using radio waves. In general, an RFID includes an antenna, a wireless circuit, a control circuit for storing and reading information, and a memory for storing information. Various names are used for RFID, such as mobile object identification devices, remote IDs, IC tags, ID tags, RF tags, wireless tags, electronic tags, and transponders. I will call it.

  For example, the setting change monitoring unit receives a signal indicating that the setting has been changed from the control unit, and determines that the setting has been changed when the signal is received.

  For example, the setting change monitoring unit monitors the setting switch and determines that the setting change has been performed when the switch is operated.

  The setting change monitoring unit monitors, for example, the power supply voltage, and determines that the setting change has been performed when detecting a power interruption for a time shorter than a predetermined time.

  For example, when receiving the signal from the setting change monitoring unit, the RFID writing unit sends a signal to the RFID to set a setting change flag.

It further includes a clock device that outputs time information,
The RFID writing unit may acquire time information from the timepiece device when receiving the signal from the setting change monitoring unit, and send the time information to the RFID for storage.

Embodiment 1 of the Invention
A gaming machine according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a gaming machine (also called a slot machine or a spinning cylinder gaming machine).
A player who wants to enjoy a game with the slot machine 10 first borrows a medal as a game medium from a medal lending machine (not shown) or the like, and inserts a medal directly into the medal insertion slot 100 of the medal insertion device. The medal slot 100 is provided at a substantially central height in front of the slot machine 10.

  The slot machine 10 has a square box-shaped housing 11. A square window-like display window 12 facing the player side is formed at the center and upper part of the casing 11. A symbol display window 13 through which the symbols 61 of the three rotary reels 40 can be seen is formed at the center of the display window 12 at the center. The bet switch 16 is a switch located below the rotary reel 40, and reduces the number of stored medals that are continuously inserted into the medal insertion slot 100 and stored to replace the medal insertion. The settlement switch 17 is a switch located obliquely below the rotating reel, and pays out the stored inserted medal. The start switch 30 is a lever positioned obliquely below the rotary reel 40 and starts driving the reel unit 60 on condition that a game medal is inserted or the bet switch 16 is operated. The stop switch 50 is for stopping the driving of the reel unit 60. The reel unit 60 is composed of three rotating reels 40. Each rotary reel 40 includes a rotary drum made of synthetic resin and a tape-like reel tape 42 attached around the rotary drum. A plurality of (for example, 21) symbols 61 are displayed on the outer peripheral surface of the reel tape 42. Reference numeral 62 denotes a liquid crystal display unit for performing various effects.

  Inside the slot machine 10, a control device for controlling the overall operation of the slot machine 10 is incorporated as will be described later. The control device is configured around a CPU and includes a ROM, a RAM, an I / O, and the like. The CPU (processing unit) is operated by reading a program stored in a ROM (storage unit) in response to the player's operation. Specifically, the CPU (processing unit) is operated by the start switch 30 and the stop switch 50. Based on this, the rotation and stop of the rotary reel 40 are controlled, and the display of lamps, speakers, and the like are controlled. Temporary data necessary for the operation of the CPU is RAM (storage unit: RAM is generally a volatile memory, and data is lost in principle when the power is turned off. A backup power source such as a battery may be prepared. In this case, data is not lost even if the power is cut off). The CPU performs a predetermined operation in accordance with a program recorded in the ROM, records temporary data necessary for processing in the RAM, and reads out and refers to the recorded data as necessary.

  The start switch 30 is a lever that is positioned obliquely below the rotary reel 40 as described above, and is a “re-game” that is obtained on condition that a game medal is inserted or the bet switch 16 is operated or according to a winning determination. "Replay)" is to start driving the reel unit 60 on condition that a predetermined time has elapsed since the previous game.

  The stop switch 50 is for stopping the driving of the reel unit 60 as described above. Specifically, the stop switch 50 includes three switches corresponding to each rotary reel 40, and one stop switch 50 is disposed below each rotary reel 40. The operation of the stop switch 50 corresponding to the rotating reel 40 is set to stop the rotation of the corresponding rotating reel 40.

  When the start switch 30 is operated on the condition that a medal is inserted or the bet switch 16 is operated, or when a predetermined time has elapsed from the previous game at the time of the “replay”, the reel unit 60 is driven and three The rotary reel 40 starts to rotate. Thereafter, when one of the stop switches 50 is operated, the rotation of the corresponding rotary reel 40 is stopped. When all three stop switches 50 are operated, the rotation of the three rotary reels 40 is stopped. At this time, if a predetermined symbol 61 on the effective pay line of the display window 13 stops, it is determined that the winning is made, and a predetermined number of medals are paid out through a hopper unit (not shown). In addition, you may credit instead of paying out medals.

  FIG. 2 is a block diagram showing an electrical schematic structure of the slot machine 10. In this figure, the display about the power supply system is omitted. The slot machine 10 includes a main substrate 1 and a sub-substrate 2 that operates in response to commands from the main substrate 1 as main processing devices. At least the main substrate 1 is accommodated inside the case so that it cannot be contacted from the outside, and a sealing process is performed so that traces remain when the substrates are removed.

  The main board 1 is for performing an internal lottery in response to a player's operation, and processing such as reel rotation / stop and medal payout. The main board 1 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub-board 2 is for receiving a command signal from the main board 1 and notifying the result of the internal lottery and performing various effects. The sub-board 2 includes a CPU that performs a control operation according to a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like. The flow of commands is only one from the main board 1 to the sub board 2, and conversely, no command or the like is issued from the sub board 2 to the main board 1.

  The main board 1 includes a start switch 30, a stop switch 50, a reel drive unit 70, a reel position detection circuit 71, a hopper drive unit 80, a hopper 81, and a medal detection unit 82 for counting the number of medals paid out from the hopper 81. Is connected. A peripheral board (local board) such as a control board 200 of the liquid crystal display device 62, a speaker 201, and an LED board 202 is connected to the sub board 2.

  The ROM of the main board 1 stores game processing procedures executed in the slot machine 10 as a sequence program, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like. Has been.

  The winning probability table is divided so that random numbers extracted by a random number generation unit (not shown) are divided into respective winning modes, and random numbers extracted from a certain range of numerical values generated by the random number generating unit are assigned to each winning mode. The data to be partitioned into is stored. That is, the winning probability table has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator. For example, a range of 0 to a certain number is divided into a plurality, one division (area) is excluded, and the other division (area) is set as winning 1, winning 2,. The extracted random number data is collated with each winning determination area data segmented for each winning mode in all the regions corresponding to the random number generated from the random number generator, and the winning mode to which the extracted random number data belongs Winning corresponding to is decided. For example, it is determined to which category (region) of the winning probability table the extracted random number value belongs, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to an out-of-range category (region) in the winning determination table 5, it is determined as “out”. For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out.

  Various winnings are generated under the probability according to the data setting of the winning probability table, and the symbol stop control is performed. For example, the operating hours of the day are not influenced by the skill of the player. The total medal payment rate is maintained almost constant. Which table is used depends on the internal setting.

  The gaming machine according to the embodiment of the present invention further includes RFID3, a writer that writes to RFID3, and a determination unit (reader) that reads and compares data in RFID3 to determine the presence or absence of fraud. . In FIG. 2, an RFID reader / writer 4 in which a general writer and a reader are combined into a single RFID is shown. The RFID reader / writer 4 includes a setting change monitoring unit 4a that monitors a setting change based on a signal related to a setting change from the sub board 2 (or the main board 1). When the setting change is performed, new setting information is sent from the main board 1 to the sub board 2, so that the sub board 2 can detect that the setting has been changed. The RFID reader / writer 4 is connected to a clock device 5 that generates a time signal (which may include calendar information). A determination unit (reader) that reads and compares data in the RFID 3 to determine whether or not there is an illegal act is not included in the gaming machine, but FIG. 2 shows information for reading information from the RFID 3 from outside the gaming machine ( An RFID reader / writer 6 (for example, handy type) is shown. The RFID reader / writer 6 includes an inspection unit 6 a that determines the presence or absence of fraud based on information read from the RFID 3.

  An RFID is a kind of electronic tag, which has electronic information inside and identifies an object by communicating with a reader using radio waves. In the embodiment of the present invention, the RFID is used as a storage unit that can be controlled wirelessly. RFID has features such as a large amount of information to be held, being able to be recognized even when separated, a number of RFIDs being simultaneously recognized, and an amount of information being held being rewritten. Although not shown, the RFID includes an antenna, a radio circuit, a control circuit for storing and reading information, and a memory for storing information.

  The RFID reader / writer 4 can communicate with the RFID 3 in the housing of the gaming machine, read the information, and write the information as necessary. For example, in the case of an electromagnetic coupling type / inductive type RFID, the RFID reader / writer 4 can communicate with the RFID by arranging a coil (antenna) close to the RFID 3. In the case of the microwave type, the RFID reader / writer 4 can communicate with the RFID 3 by directing the directional antenna toward the RFID 3 or using the omnidirectional antenna.

  Although not shown, the RFID reader / writer 4 includes an antenna, a wireless circuit, a control circuit for storing information in the RFID and reading information from the RFID, a display device for displaying information, and other devices. A network device for communicating with the computer. The RFID reader / writer 4 according to the embodiment of the present invention includes a setting change monitoring unit 4a as its function. The setting change monitoring unit 4a may be realized by hardware such as a CPU added to the RFID reader / writer 4, or may be realized by software by adding a program to the RFID reader / writer 4. The same applies to the inspection unit 6a of the RFID reader / writer 6.

  Next, a procedure for changing the internal setting will be specifically described.

FIG. 3 shows a front view of the power panel 205 of the gaming machine. Each switch of the power supply panel 205 is connected to the main board 1.
In FIG. 3, a power switch 2051 is a power on / off switch, a power supply pilot lamp 2052 is a lamp (LED) that is lit when the power is on, and a stop presence / absence switch 2053 is a stop that limits the number of medals to be paid out. Is a switch for setting “Yes” or “No”. The stop / presence switch 2053 is normally set to “none” and is not frequently used. The setting key switch 2054 is a switch for enabling the setting, the setting change / reset switch 2055 is a switch for changing the setting or resetting the apparatus, and the AC100V pilot lamp 2056 is a power source of the casing. The lamp indicates that AC 100 V is supplied, and the AC power output and power cable 2057 are for supplying power.

Next, processing for changing the internal setting will be described with reference to FIG. In order to change the internal setting for selecting the winning probability table, the following procedure is required.
S1: The power switch 2051 is turned off. When the power is turned off and then turned on again, the control unit (main board 1) looks at the state of the setting key switch 2054 at that time and performs a setting change process according to the state.
S2: The setting key switch 2054 is turned on. Normally off.
S3: The power switch 2051 is turned on. As a result, power is supplied to the gaming machine. Since the setting key switch 2054 is on, a setting change command is output.
S4: When the setting change command is output, the control unit enters the setting change mode.
S5: Turn the setting key switch 2054 clockwise to turn it ON, and then press the setting change / reset switch 2055 to select the internal setting. The value of the internal setting is displayed on a display device (not shown) (for example, an LED numeric display on the front surface of the housing). The internal setting can be set, for example, in 1 to 6 stages. When the switch 2055 is operated, the displayed set value changes.
S6: When the desired set value is reached, the start lever 30 is operated.
S7: The set value is determined by the operation of S6.
S8: The setting key switch 2054 is turned off. Then, the set value is stored in the memory in the main board 1, and the set value display on a display (not shown) disappears.
S9: The RAM of the main board 1 is initialized, and an initialization command and an internal setting command are sent to the sub board 2. In response to the initialization command, the sub-board 2 initializes the RAM and the like.

  In order to monitor whether the setting has been changed, whether or not the above processing has been performed (simply whether an initialization command or an internal setting command has been sent to the sub-board 2), the setting key switch 2054, the setting change / It is only necessary to monitor whether the reset switch 2055 has been operated and whether the power has been turned on again. In the first embodiment of the invention, the setting change monitoring unit 4a monitors setting changes based on an initialization command or an internal setting command.

  The processing of the first embodiment of the invention will be described with reference to FIGS.

FIG. 5 shows a flowchart of the setting change monitoring process in the gaming machine.
S10: It is determined whether the setting change monitoring unit 4a has received a signal indicating a setting change. Specifically, an initialization command or a setting change command sent from the main board 1 to the sub board 2 after the setting change is received. In FIG. 2, when the sub-board 2 receives an initialization command or a setting change command, a signal to that effect is sent to the setting change monitoring unit 4a. You may make it monitor the command to the board | substrate 2 directly.
S11: When a signal indicating a setting change is received by the setting change monitoring unit 4a (YES in S10), the time at that time is recorded.
S12: The RFID 3 is instructed to set a setting change flag, and the time recorded in S11 is sent and stored.
S13: The RFID 3 raises and holds the setting change flag and stores the time when the flag is established.

  With the processing in FIG. 5, a setting change flag is set every time a setting change is made, and the time is stored. When the setting is changed a plurality of times, the number of setting change flags and time corresponding to the number of times are stored. These are stored until a reset command is received.

Next, processing of the RFID reader / writer 6 will be described with reference to FIG. The RFID reader / writer 6 corresponds to an inspection device for a gaming machine.
S20: Requests transmission of the stored setting change flag and its establishment time information to RFID3. After the RFID reader / writer 6 is installed near the gaming machine so that it can communicate with the RFID 3, the RFID 3 is requested to transmit information.
S21: The setting change flag and information on the establishment time are received from the RFID3. When there are a plurality of setting change flags, each is accompanied by time information. When there are three setting change flags, it is as follows.
(Setting change flag 1): (Time information 1)
(Setting change flag 2): (Time information 2)
(Setting change flag 3): (Time information 3)

S22: It is determined whether or not the number of setting change flags exceeds a predetermined threshold value. When it exceeds (YES), it determines with an illegal act and performs error alerting | reporting (S26).
The setting change is not performed so frequently, but once per day before the start of business or after the end of business. If the settings are changed frequently, it can be considered that the settings are changed illegally. From this point of view, a threshold value (for example, once) is provided for the number of setting changes, and when this value is exceeded (when it becomes two or more times), it can be determined as an illegal act. In the above example, since the setting change has been performed three times, it is determined as an illegal act.

S23: It is determined whether the establishment time of the setting change flag is within business hours. Information on business hours is stored in advance. If it is within business hours (YES), it is determined as an illegal act and an error notification is made (S26).
Usually, since the setting change is performed before the start of business or after the end of business, if the time information attached to the setting change flag is within the predetermined business hours, it can be considered that the setting is changed illegally.
S24: When it does not correspond to either S22 or S23, it is determined that there is no fraud.
S25: A reset command is transmitted to RFID3. In order to prevent the accumulation of setting change flags, it is preferable to reset the stored contents at appropriate intervals. For example, when the RFID reader / writer 6 inspects once a day, the content of the RFID is reset when it is determined that there is no abnormality in the inspection.

  In FIG. 5, the setting change flag and the time information are stored in the RFID. However, only one of them may be stored, and based on this, the presence / absence of fraud may be determined. Depending on the stored information, any one of S22 and S23 of the fraud determination process of FIG. 6 may be performed.

Embodiment 2 of the Invention
In the second embodiment of the present invention, a setting change is detected by monitoring a switch operated when the setting is changed.

  FIG. 7 shows a block diagram of the second embodiment of the invention. The figure shows only the main part. The setting change monitoring unit 4a is connected to at least a part of the power switch 2051, the setting key switch 2054, and the setting change / reset switch 2055 of the power panel 205, and monitors whether these switches have been operated. As described above, since these switches are always operated when the setting is changed, the presence or absence of the setting change can be determined by monitoring these switches. The setting key switch 2054 is preferable because it is operated only when the setting is changed.

FIG. 8 shows a flowchart of the setting change monitoring process according to the second embodiment of the invention.
S10b: It is determined whether or not the switches (power switch 2051, setting key switch 2054, setting change / reset switch 2055 of the power panel 205) used for setting change have been operated. Specifically, the change of the output signal of the switch can be monitored and determined. When the switch is turned on, the voltage level is normally at the L level.
S11: When an operation on a switch used for setting change is detected (YES in S10b), the time at that time is recorded.
S12: The RFID 3 is instructed to set a setting change flag, and the time recorded in S11 is sent and stored.
S13: The RFID 3 raises and holds the setting change flag and stores the time when the flag is established.

  As in the case of the first embodiment of the invention, the setting change flag is set and the time is stored by the processing of FIG. Since the fraud determination process is the same as that in the first embodiment, the description thereof is omitted.

Embodiment 3 of the Invention
In the third embodiment of the present invention, the setting change is detected by monitoring the power interruption that is performed when the setting is changed.

  FIG. 9 shows a block diagram of Embodiment 3 of the invention. The figure shows only the main part. The setting change monitoring unit 4a monitors a DC power supply voltage output from a power supply unit (not shown) in the gaming machine casing, and monitors whether the power supply is cut off. As described above, since it is necessary to turn off the power once in order to make the setting change effective, it is possible to determine the presence or absence of the setting change by monitoring this. When changing the setting, the power is usually turned off once and then turned on again in a short time. From this point of view, the setting change monitoring unit 4a monitors a power interruption for a short period (for example, several seconds to several tens of seconds), and determines that a setting change has been made when such a power interruption is detected.

FIG. 10 shows a flowchart of the setting change monitoring process according to the third embodiment of the invention.
S10c: The setting change monitoring unit 4a monitors the power-off in a short period (for example, several seconds to several tens of seconds or less) and determines whether or not the setting change has been performed.
S11: If power-off performed at the time of setting change is detected (YES in S10c), the time at that time is recorded.
S12: The RFID 3 is instructed to set a setting change flag, and the time recorded in S11 is sent and stored.
S13: The RFID 3 raises and holds the setting change flag and stores the time when the flag is established.

  As in the case of the first embodiment of the present invention, the setting change flag is set and the time is stored every time the setting is changed by the processing of FIG. Since the fraud determination process is the same as that in the first embodiment, the description thereof is omitted.

  According to the first to third embodiments of the present invention, the RFID 3 and the RFID reader / writer 4 are provided in the gaming machine, and the RFID reader / writer 4 causes the RFID 3 to write information updates in accordance with changes in the internal control system. The updated information is read and managed in a non-contact manner by the RFID reader / writer 6 provided outside the gaming machine casing. Specifically, by operating the RFID reader / writer 4 in response to the confirmation of the setting change operation, the fact that the RFID 3 was changed and the change operation time are written, and information on the RFID 3 where the writing was performed The read information stored in the RFID 3 is compared with a predetermined criterion such as “whether or not the storage is within the business hours” or “there is a plurality of storages”. It is now possible to detect cheating by judging

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
