Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an unlocking system for a gaming machine.
[0002]
[Prior art]
Conventionally, an unlocking system capable of remotely unlocking a lock provided on a frame body (for example, a front frame or a glass frame) provided in a gaming machine (for example, a ball game machine or a revolving type gaming machine). It has been known. This type of unlocking system includes a data transmission device capable of wirelessly transmitting key-side data for instructing unlocking, and an actuator that operates when the key-side data is received. And an unlocking device that switches the lock provided on the body from the locked state to the unlocked state.
[0003]
By the way, in the above conventional unlocking system, the data transmitting device is configured to transmit the key side data read from the built-in memory to the unlocking device side when receiving an operation from the user. When some data is received, the received data is compared with the lock side data read from the internal memory of the unlocking device, and when the received data is appropriate data as a result of the verification, It was configured to switch from the locked state to the unlocked state.
[0004]
Both the key-side data on the data transmitting device side and the lock-side data on the unlocking device side are stored in a rewritable non-volatile memory or the like. For example, by using different data for each game hall, a certain game hall The data transmission device cannot operate the unlocking device of another game hall. In addition, if the data transmission device is lost or the data transmission device is stolen, the lost or stolen data transmission device can be disabled by rewriting the lock data with another data. I was able to.
[0005]
[Problems to be solved by the invention]
However, in the above conventional unlocking system for gaming machines, when a pulse signal of key data is stolen by a device capable of storing a pulse signal transmitted from the outside (a device called a so-called learning remote controller). In addition, since the data transmission device itself was not stolen, there was a risk that the damage to the amusement hall side would increase without noticing that such a situation occurred.
[0006]
In addition, in the case where each unlocking device provided for each gaming machine stores the lock side data, when the data transmitting device is lost or the data transmitting device is stolen, it is in the game hall. Since all the unlocking devices have to rewrite the lock side data, there is also a problem that a great deal of labor is required for the rewriting work.
[0007]
The present invention has been made to solve the above problems, and an object of the present invention is to provide an unlocking system for a gaming machine having higher crime prevention performance against unauthorized transmission of key-side data than conventional products.
[0008]
[Means for Solving the Problems and Effects of the Invention]
  In order to achieve the above object, an unlocking system for a gaming machine according to the present invention includes:
  Reads the key-side data from the rewritable storage means and wirelessly transmits the key-side data, and when the wirelessly transmitted data is received, the received data and the lock-side data are By checking, it is determined whether or not the received data is the key-side data. If the received data is the key-side data, the actuator is operated to activate the lock provided on the frame of the gaming machine. In an unlocking system for a gaming machine comprising an unlocking device that switches from a locked state to an unlocked state,
Furthermore, it is a device having a function of updating the key data stored in the storage means of the data transmission device, comprising a data update device configured as a separate device from the data transmission device,
  The unlocking device stores data determined according to the date or the date and time.Create,The created dataConfigured to be used as the lock side data,
The data update device is also configured to create data determined according to date or date and update the key data stored in the storage unit of the data transmission device with the created data,
The data transmission device is configured to update the key data using the data update device.
  It is characterized by that.
[0009]
In this unlocking system for gaming machines, the lock makes the frame of the gaming machine unopenable at least when locked. However, there are cases where two or more locks are provided for the frame as a security measure. In that case, any one or more of the two or more locks corresponds to the lock of the present unlocking system, and the remaining 1 Since the above locks may become locks that are not linked to this unlocking system, if only the locks of this unlocking system are unlocked, is the frame of the gaming machine ready to be opened? It is not certain whether or not. In addition, as a method of providing two or more locks to the frame body, there is a method of providing two or more locks that are in a state of preventing the opening operation itself of the frame body when the locked state is reached. In addition to the first lock that is in a state of preventing the opening operation itself, there is also a method of providing a second lock that makes the movable part of the first lock not move when in the locked state. However, both the first lock and the second lock may independently correspond to the locks used in the present unlocking system.
[0010]
Moreover, the lock | rock side data which an unlocking apparatus uses at the time of collation are data determined according to a date or a date. When using the same lock side data in units of one day, it is sufficient to use data determined according to the date. For example, numerical data representing a date, numerical data convertible to numerical data representing a date, numerical data representing a date Any data can be used as long as it is associated with a date, such as data obtained by performing a predetermined operation on the data, or data read from a predetermined table using numeric data representing a date as a key. Further, when it is desired to change the lock side data in units of half a day or several hours, data determined according to the date and time may be used. The number of data on the lock side increases the crime prevention performance as the number of possible data variations increases. However, if the number is too large, it is practically useless. Data level) is sufficient, and if it is set to several thousand to tens of thousands, it is almost impossible to accidentally detect the lock side data.
[0011]
The date and date and time used as the basis for determining the lock side data may be acquired from a calendar clock built in the unlocking device, or if the unlocking device is connected to a network such as a LAN, You may get it. Moreover, the data itself determined according to the date or the date and time may be acquired by the unlocking device from the data providing means outside the unlocking device. Data related to the date or date and time that can be acquired by the unlocking device is not necessarily data that changes only at the expected update timing. For example, data that changes in seconds (such as the cumulative time from the reference time expressed in seconds) Numerical data), and in that case, it is converted to data that fluctuates only at the desired update timing, for example by dividing by the number of seconds of the cumulative time corresponding to the expected update interval, The lock side data may be determined based on the conversion result.
[0012]
In addition, if a part of the lock side data is updated, it will be updated as a whole even if another part is not updated. In addition, an individual ID code assigned to each amusement hall may be included.
[0013]
The communication method between the data transmission device and the unlocking device may be an infrared communication method or a radio wave communication method as long as it is wireless. Alternatively, by adopting both of these methods at the same time and performing the unlocking process only when both types of communication are established, it is possible to prevent unauthorized unlocking with either infrared or radio waves alone. May be. In addition, when both of these methods are adopted at the same time and the unlocking process is performed even if either one of the communication methods is established, there is a problem with either infrared or radio wave reception sensitivity. However, the unlocking process may be executed smoothly. Which of these methods is adopted can be arbitrarily selected in consideration of whether the emphasis is on countermeasures against unauthorized unlocking or countermeasures on reception sensitivity.
[0014]
According to the unlocking system for gaming machines configured as described above, the unlocking device uses data determined according to the date or the date and time as the lock-side data without any operation by the user. Therefore, after the lock side data used by the unlocking device becomes new data as the date or date / time changes, it is necessary to transmit the key side data suitable for the new lock side data from the data transmitting device side. The unlocking device will not operate.
[0015]
Therefore, even when the key pattern pulse pattern itself is stolen by using a device (so-called learning remote controller, etc.) that can store the key pattern pulse pattern transmitted wirelessly from the data transmitter in the memory, the time After the unlocking device uses new lock side data with the passage of time, the stolen pulse pattern can no longer be used, so it is possible to prevent excessive damage on the game hall side .
[0016]
In addition, when the data transmission device is lost or the data transmission device is stolen, it is not necessary to perform troublesome work such as rewriting the lock side data to another data for all unlocking devices in the game hall. After the unlocking device uses the new lock side data, the data transmitting device cannot be used, so that there is no problem that much work is required for rewriting the lock side data.
[0017]
  In this unlocking system for gaming machines, for the data transmission device, it is necessary to update the key side data every time the unlocking device uses new lock side data. It should be prevented from being easily implemented by an unauthorized person who obtained the data transmission device.In this regard, the unlocking system for gaming machines of the present invention is, Key-side data cannot be updated unless a data update device separate from the data transmission device is used.BecauseStrictly manage the data update deviceIfGood.
[0018]
Now, the unlocking system for gaming machines described above may be further configured as follows.
First, about the unlocking device,
The unlocking device may be configured to use, as the lock-side data, data determined according to a date or a date and time acquired when receiving data transmitted wirelessly.
[0019]
According to such an unlocking system for gaming machines, the lock side data corresponds to the date or the date and time acquired when the data transmitted wirelessly is received. For example, the lock side data can be changed between morning and afternoon.
[0020]
Or the data determined according to the date acquired when the said unlocking apparatus started may be comprised so that it may use as said lock | rock side data.
According to such an unlocking system for a gaming machine, the lock side data is determined at the time of starting, and thereafter is not changed until the next starting time. Even if the change occurs, the data transmission device does not become unusable.
[0021]
Further, the data transmission device may be configured to transmit the key side data when receiving an operation from a user.
According to such an unlocking system for a gaming machine, the data transmission device transmits key-side data only when necessary, so that power consumption of the data transmission device can be suppressed.
[0022]
Or
The data transmission device continues to transmit the key side data during operation;
When the unlocking device receives the key side data, the lock is switched to the unlocked state, and when the key side data cannot be received, the lock is switched to the locked state. Good.
[0023]
According to such an unlocking system for a gaming machine, the data transmitting device approaches the unlocking device to a certain extent by adjusting the relationship between the transmission intensity from the data transmitting device and the receiving sensitivity on the unlocking device side. The unlocking device can switch the lock to the unlocked state, and when the data transmitting device is separated from the unlocking device to a certain extent, the unlocking device can be switched to the locked state. However, even if the data transmission device is not operated, the lock can be unlocked only by approaching the unlocking device while holding the data transmission device.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with an example.
As shown in FIG. 1, the unlocking system for the gaming machine is configured by a data transmission device 1 carried by a game attendant and an unlocking device 2 provided for each gaming machine. In the present embodiment, as shown in FIG. 2, the key-side data stored in the data transmission device 1 can be updated using the data update device 3 that is separate from the data transmission device 1. ing.
[0025]
Among these, the data transmission device 1 includes a control unit 11, a transmission unit 13, a reception unit 15, an operation unit 17, and a display unit 19.
The control unit 11 includes an input / output interface circuit for the transmission unit 13 and an input / output interface circuit for the reception unit 15 centering on a one-chip computer in which a CPU, ROM, RAM, and the like are incorporated on an LSI chip. Is. The non-volatile memory built in the control unit 11 stores key side data. This key-side data is data transmitted from the data updating device 3 to be described in detail later, and corresponds to the date which is data determined according to the game hall identification code assigned to each game hall and the date. Data composed of codes.
[0026]
The transmission unit 13 includes an LED that emits infrared rays when energized and a drive circuit for the LED. The transmission unit 13 is capable of transmitting an infrared pulse signal having a pulse pattern commanded from the control unit 11 by controlling the control unit 11 to blink the LED.
[0027]
The receiving unit 15 includes a phototransistor capable of detecting an infrared pulse signal and a drive circuit for the phototransistor. The receiving unit 15 can receive an infrared pulse signal coming from the outside.
The operation unit 17 includes a button group that is operated when the user uses the data transmission device 1 and an electric circuit that transmits the ON / OFF operation status of the button group to the control unit 11.
[0028]
The display unit 19 includes a liquid crystal display and a drive circuit thereof, and can display the operation mode of the data transmission device 1 and various messages.
It should be noted that at least one data transmission device 1 configured as described above is sufficient for configuring the present unlocking system, but a plurality of data transmission devices 1 may exist in the present system. In practice, it is more convenient for each of the plurality of game hall staff to have the data transmission device 1.
[0029]
The unlocking device 2 includes a control unit 21, a receiving unit 23, and a lock driving unit 25.
The control unit 21 is a one-chip computer that incorporates a CPU, ROM, RAM, etc. on an LSI chip, and a calendar clock that measures the number of seconds accumulated from a reference time, and an input / output for the receiving unit 23. An interface circuit, an input / output interface circuit for the lock drive unit 25, an input / output interface circuit for the hall computer C, and the like are provided. A non-volatile memory built in the control unit 21 stores a game hall identification code used as part of the lock side data. This game hall identification code is the same code as the game hall identification code in the key side data described above. The lock side data is composed of this game hall identification code and a date corresponding code which is data determined according to the date. The date correspondence code is not stored in the nonvolatile memory, and is created in the control unit 21 when necessary.
[0030]
In the present embodiment, a method for creating a date correspondence code is as follows. That is, the control unit 21 of the unlocking device 2 stores a random number table in which 9999 numbers from 0001 to 9999 are arranged in an irregular order in the ROM, and the CPU of the control unit 21 controls the control unit 21. The current cumulative number of seconds s is obtained from the calendar clock, and the cumulative number of seconds s is divided by the number of seconds of the day (24 × 60 × 60) to convert the cumulative number of seconds s to the cumulative number of days d. Then, the cumulative number of days d is further divided by 9999 to obtain a remainder n (n is one of integers satisfying 0 ≦ n ≦ 9998). Based on this remainder n, the (n + 1) th residue in the random number table is obtained. A value is read, and the read value is used as a date correspondence code. When the date correspondence code is determined by such a method, the date correspondence code is a value that varies from 0001 to 9999 every day in an irregular order defined in the random number table, with 9999 days as one cycle. The fluctuation pattern is repeated after the next period. Therefore, unless the random number table is known to the third party, it is impossible for the third party to guess the date correspondence code. On the other hand, if the random number table is known, the cumulative number of seconds s obtained from the calendar clock is used. Based on this, the date correspondence code can be uniquely specified.
[0031]
The receiving unit 23 includes a phototransistor capable of detecting an infrared pulse signal and a drive circuit for the phototransistor, and can receive an infrared pulse signal coming from the outside. The receiving unit 23 is incorporated in a calling lamp (not shown) disposed on the upper part of the gaming machine and is arranged so as to receive an infrared pulse signal emitted from the front side of the gaming machine toward the calling lamp. The
[0032]
The lock drive unit 25 includes a solenoid, a power transmission mechanism that transmits power from the solenoid to the lock R provided on the front frame of the gaming machine, and a drive circuit for the solenoid. The lock drive unit 25 can be switched to either the locked state or the unlocked state by being controlled by the control unit 21 and operating the solenoid.
[0033]
Note that the unlocking device 2 configured as described above is usually provided with the same number of unlocking devices 2 as the gaming machine to be unlocked.
Further, the data update device 3 includes a control unit 31, a transmission unit 33, a reception unit 35, an operation unit 37, and a display unit 39.
[0034]
The control unit 31 is a one-chip computer in which a CPU, ROM, RAM, etc. are incorporated on an LSI chip, and is a calendar clock that measures the number of seconds accumulated from a reference time. An input / output interface for the transmission unit 33 A circuit is provided. The non-volatile memory built in the control unit 31 stores a game hall identification code that is transmitted to the data transmitting device 1 side when the key side data is updated. When the key side data is updated, the date correspondence code is also transmitted to the data transmitting apparatus 1 side, but the date correspondence code is not stored in the nonvolatile memory and is created by the control unit 31 when necessary.
[0035]
The creation method of the date correspondence code is exactly the same as that of the unlocking device 2, and the same random number table as the random number table stored in the control unit 21 of the unlocking device 2 is stored in the ROM of the control unit 31. ing. Therefore, when the date correspondence code is specified in the same procedure as the unlocking device 2 based on the accumulated number of seconds s acquired from the calendar clock of the control unit 31, the data updating device 3 also unlocks the device according to the date of the day. The date correspondence code exactly the same as 2 is created.
[0036]
The transmission unit 33 includes an LED that emits infrared rays when energized and a drive circuit for the LED. The transmission unit 33 is controlled by the control unit 31 and transmits an infrared pulse signal having a pulse pattern commanded by the control unit 31 to the data transmission device 1. And can be sent.
The receiving unit 35 includes a phototransistor capable of detecting an infrared pulse signal and a drive circuit for the phototransistor. The receiving unit 35 can receive an infrared pulse signal coming from the outside.
[0037]
The operation unit 37 includes a button group that is operated when the user uses the data update device 3 and an electric circuit that transmits the ON / OFF operation status of the button group to the control unit 31.
The display unit 39 is composed of a liquid crystal display and its driving circuit, and can display the operation mode of the data update device 3 and various messages.
[0038]
  Note that there may be a plurality of such data update devices 3, but one data update device 3 can be used to perform data update processing for a plurality of data transmission devices 1. A data update device 3 is sufficient..
[0039]
Next, the operation | movement aspect of this unlocking system is demonstrated.
First, when using this unlocking system, as a preliminary preparation, the same time (usually the current time) is set in the calendar clock built in the control unit 21 of the unlocking device 2 and the control unit 31 of the data updating device 3. Set it. Once this pre-preparation is carried out, it need not be carried out again unless the time of the calendar clock is significantly upset.
[0040]
Next, before the unlocking process is actually performed using the data transmission apparatus 1, the data update process for the data transmission apparatus must be performed. This data update process must be performed every day before the use of the data transmission device 1 is started.
When starting the data update process, first, the power switches of the data transmission device 1 and the data update device 3 are turned on so that the reception unit 15 of the data transmission device 1 and the transmission unit 33 of the data update device 3 face each other. To place. In this state, the user presses the data update button on the operation unit 17 of the data transmission device 1.
[0041]
At this time, as shown in FIG. 3, the data transmission device 1 is in a standby state until the data update button is pressed (S101: NO), but when the data update button is pressed (S101: YES), Update request data is transmitted by the infrared pulse signal from the transmitter 13 (S103).
[0042]
On the other hand, the data update device 3 enters a reception standby state in which update request data can be received (S201). When the update request data is not received (S203: NO), the data update device 3 continues the reception standby state. Here, when the update request data transmitted from the data transmission device 1 is received (S203: YES), the game hall identification code is read from the built-in nonvolatile memory, and the date correspondence code is created by the above-described method. Key-side data is created by combining the codes (S205). Then, the key side data is transmitted from the transmitter 33 by an infrared pulse signal (S207). Note that after finishing the processing of S207, the processing is finished as it is, but if necessary, the processing may return to the processing of S201 to prepare for processing for another data transmitting apparatus 1.
[0043]
Now, after finishing the process of S103, the data transmitting apparatus 1 enters a reception standby state in which the key side data can be received (S105), does not receive the key side data (S107: NO), and is not timed out. (S109: NO), the reception standby state is continued. Here, when the key side data transmitted from the data update device 3 is received (S109: YES), the data transmission device 1 stores the new key side data in the nonvolatile memory storing the previous key side data. And the key side data is updated (S111). Then, a message indicating that the data update has been completed normally is displayed on the display unit 19 (S113). If time-out occurs while key-side data cannot be received normally (S109: YES), a message indicating that the data update has not been completed normally is displayed on the display unit 19 (S115).
[0044]
Through the processing described above, the user can check whether the key data has been updated by viewing the message displayed on the display unit 19 after operating the operation unit 17 of the data transmission device 1. .
Next, when the unlocking device 2 is operated using the data transmitting device 1 that has completed the data update process as described above, the transmitting unit 13 of the data transmitting device 1 is connected to the receiving unit 23 of the unlocking device 2. The user presses the unlock button on the operation unit 17 of the data transmission device 1.
[0045]
At this time, as shown in FIG. 4, the data transmitting apparatus 1 is in a standby state until the unlock button is pressed (S301: NO), but when the unlock button is pressed (S301: YES), Key-side data is transmitted from the transmitter 13 by an infrared pulse signal (S303). The key side data is data written in the nonvolatile memory of the control unit 11 by the data update process described above. The above processing is executed each time the unlock button is pressed.
[0046]
On the other hand, the unlocking device 2 has been in a reception standby state in which key side data can be received from the start of operation (S401), and when the key side data has not been received (S403: NO), the reception standby state is set. continue. Here, when the key side data transmitted from the data transmission device 1 is received (S403: YES), the game hall identification code is read from the built-in nonvolatile memory, and the date correspondence codes are created by the above-described method. The lock side data is created by combining the codes (S405). Then, the key-side data received in the process of S401 and the lock-side data created in the process of S405 are collated, and if they match (S407: YES), the lock driving unit 25 is operated. (S409), the lock R is switched from the locked state to the unlocked state. On the other hand, if the key-side data received in the process of S401 and the lock-side data created in the process of S405 do not match (S407: NO), the process ends.
[0047]
After the processing of S411, the opening and re-closing of the front frame of the gaming machine is detected, and the lock R is returned from the unlocked state to the locked state, or the front frame is not opened for a predetermined time ( For example, when 30 seconds have elapsed, it is desirable to take measures to prevent unauthorized opening of the front frame, such as returning the lock R from the unlocked state to the locked state, but these measures are not the main part of the present invention. Detailed description thereof will be omitted.
[0048]
According to the unlocking system for gaming machines described above, since the date correspondence code in the lock side data is updated to new contents every day in the unlocking device 2, the key side data stored in the data transmitting device 1 is updated. If the content is not updated to new contents every day, the data transmission device 1 cannot be used, and the key-side data read from the data transmission device 1 in the past cannot be used.
[0049]
Therefore, even if the data transmission device 1 is stolen or the pulse pattern of the key side data itself is stolen using a device that can store the pulse pattern of the key side data in a memory (so-called learning remote controller or the like) The next day, the stolen data transmission device 1 and the pulse pattern of the key data can no longer be used. It can prevent excessive damage from occurring.
[0050]
Further, when the data transmission device 1 is lost or the data transmission device 1 is stolen, the troublesome work of rewriting the lock side data to another data for all the unlocking devices 2 in the game hall is performed. Even if it is not, since the data transmitting device 1 cannot be used after the unlocking device 2 uses new lock-side data, it requires a great deal of labor to rewrite the lock-side data. There is no.
[0051]
  As mentioned above, although embodiment of this invention was described, this invention can be implemented also with forms other than the above, and is not limited to said specific form. In the following, another useful embodiment will be described..
[0052]
UpIn the embodiment, when the user operates the data transmission device 1, the key-side data is transmitted and the unlocking device 2 is activated, but the key-side data is transmitted by radio waves. Alternatively, the data transmission device 1 may continuously transmit the key side data. In this case, even if the user does not bother to perform the operation, the unlocking device 2 can be operated only by the data transmitting device 1 approaching the unlocking device 2, so that the user can perform the operation. Save time and effort. However, in such a configuration, the lock is automatically unlocked as the data transmission device 1 approaches, so that the lock is automatically locked when the data transmission device 1 is separated to some extent. Should be configured to return. The degree to which the door is unlocked and the degree to which the door is unlocked can be arbitrarily adjusted by adjusting the relationship between the transmission intensity on the data transmitting device 1 side and the receiving sensitivity on the unlocking device 2 side. can do.
[0053]
In the above embodiment, the lock side data is created immediately after receiving the key side data. However, when the unlocking device 2 is started, the lock side data is created and stored in the memory. When using the data, the lock side data stored in the memory may be used. In this way, the lock side data is determined at the time of starting and is not changed thereafter until the next time of starting. Therefore, even if the date changes during the operation of the unlocking device 2, the data transmitting device 1 suddenly changes. There is no such thing as being unusable.
[0054]
In the above embodiment, since the lock side data is determined based on the date, the lock side data is supposed to be changed after midnight. If the data is determined, the lock side data can be changed at a time other than midnight. Further, if the lock side data is determined in consideration of the time, the lock side data can be changed at the timing of two or more times a day. In addition, even if the lock side data is changed after midnight as in the above embodiment, if the time set in the calendar clock built in the unlocking device 2 is intentionally advanced or delayed, It is possible to change the lock side data at a time other than midnight, for example, if you want to change the lock side data at 3 am For example, the time set in the calendar clock built in the unlocking device 2 may be intentionally delayed by 3 hours.
[0055]
In addition, in the amusement hall, when it is desired that the unlocking operation cannot be performed unless a separate data transmission device 1 is used for each gaming island, an ID assigned to each gaming island is embedded in the key side data and the lock side data. There is also a method, but in the case of the unlocking system of the above embodiment, the lock side data becomes different simply by setting another date on the calendar clock built in the unlocking device 2. By setting the date set to the calendar clock to be different for each game island, the unlocking operation cannot be performed without using the data transmission device 1 corresponding to that date.
[0056]
In the above embodiment, the unlocking device 2 is applied to the lock of the front frame of the gaming machine, but it is used for unlocking the glass frame provided in various ball game machines such as pachinko machines and arrange balls. You can also Moreover, as a gaming machine, in addition to a ball game machine such as a pachinko machine or an arrangement ball, a revolving game machine or the like can be applied.
