In FIG. 1, the example of a structure of the game store which has implemented the key management system which consists of the store 1 of the game store and its management office 2 is shown. The key 11 managed in the gaming store is inserted into a lock keyhole provided in each of the gaming machines, and, for example, when rotated to the right, the lock of the door of the gaming machine is unlocked and rotated to the left. Only the frame of the gaming machine is unlocked, and any lock is locked. Note that the door and frame unlocking with respect to the rotation direction may have the reverse relationship described above. In addition, since this key has a common code, the lock of all the gaming machines can be unlocked and locked with one key 11. Further, a plurality of keys 11 are prepared, and are normally stored in the key storage 21 of the management office 2. The battery 54 is built in upon receiving power supply from the key storage 21 as necessary. (FIG. 5) is charged.

  Furthermore, the key 11 detects its own operating state by detecting insertion into the keyhole and rotation. The key 11 communicates wirelessly with an access point (hereinafter referred to as an AP) 13 installed by associating the detected information of its own operating state with the position of the gaming machine, and the administrative office via the AP 13. It is transmitted to the hall computer 22 installed at the station 2. The communication between the key 11 and the AP 13 is short-range wireless communication using, for example, Bluetooth. In FIG. 1, it is shown that APs 13-1 to 13-160 are provided in accordance with the arrangement of the gaming machines. In FIG. 1, the gaming machine is not described, but it is assumed that it is installed corresponding to each position of the AP 13. Further, when it is not necessary to distinguish each of the APs 13-1 to 13-160, the AP 13-1 to 13-160 are simply referred to as AP 13, and other configurations are also referred to in the same manner.

  Moreover, in the store 1 of FIG. 1, the gaming machine is provided in the island facilities A to H, and the AP 13 is installed correspondingly. That is, in FIG. 1, AP13-1 thru | or 13-20 are provided corresponding to the gaming machine installed in the island equipment A, and AP13-21 thru | or corresponding to the gaming machine installed in the island equipment B 13-40 are provided, AP13-41 to 13-60 are provided corresponding to the gaming machines installed on the island facility C, and AP13- is provided corresponding to the gaming machines installed on the island facility D. 61 to 13-80 are provided. Similarly, APs 13-81 to 13-100 are provided corresponding to the gaming machines installed in the island facility E, and APs 13-101 to 13-120 are corresponded to the gaming machines installed in the island facility F. AP13-121 to 13-140 are provided corresponding to the gaming machines installed in the island facility G, and AP13-141 to 13- corresponding to the gaming machines installed in the island facility H. 160 is provided.

It also has a management function to manage

  The take-out number table 191a manages solid identification numbers for individually identifying the keys 11 taken out from the key storage 21 as a table. The history time table 191b manages information on the time taken out from the key storage 21 and the return time as a table in association with individual identification numbers for individually identifying the keys 11. The unconnected time table 191c manages, as a table, the time elapsed from the time when communication with the AP 13 was recently performed for each individual identification number for identifying the key 11. The AP table 191d manages the AP 13 and the gaming machine number (unit number) of the nearest gaming machine installed in association with the AP 13 as a table. The radio wave intensity table 191e manages the radio wave intensity received by the AP 13 by communication with the key 11 as a table in association with the solid identification number for identifying the key 11 and the solid identification number for identifying the AP 13.

The state information is stored and managed as a history including a table associated with the time information generated by the RTC 195. The position specifying unit 191g specifies the position of each key 11 based on the distribution of the radio wave intensity stored in the radio wave intensity table 191e. That is, for example, the position specifying unit 191g determines the position of the key 11 near the gaming machine with the gaming machine number (unit number) installed in association with the AP 13 communicating with the strongest radio wave intensity for each key 11. Identify as a location.

The communication unit 194 communicates with the AP 13 wirelessly or by wire, and exchanges various data or programs. The RTC 195 generates real-time time information and supplies it to the control unit 191.

The operation unit 199 is the same as the operation unit 22b, and includes operation buttons and a keyboard. The operation unit 199 generates an operation signal according to a user operation and outputs the operation signal to the control unit 191.

[Key management process using keys]
Next, the key management process using the key 11 will be described with reference to the flowchart of FIG.

  In step S1, the control unit 105 controls the time measurement unit 105e to initialize the timer 109 and start counting the count value as a timer.

  In step S <b> 2, the remaining voltage recognition unit 105 c of the control unit 105 controls the power supply control unit 121 to inquire about the charging voltage of the battery 54, acquires the current remaining voltage, and confirms the remaining voltage as the remaining battery level.

  In step S3, the remaining voltage recognizing unit 105c determines whether the current remaining battery level is less than 20% when the remaining battery level in the fully charged state is 100% based on the remaining voltage. To do. If it is determined in step S3 that the state of charge is not less than 20%, the process proceeds to step S4.

  In step S4, the remaining voltage recognition unit 105c stores information on the remaining voltage, which is information on the current remaining battery level.

  In step S5, the control unit 105 controls the insertion recognizing unit 105a to determine whether or not a signal indicating that the key 11 has been inserted into a keyhole (not shown) from the key insertion detecting unit 101 has been supplied. To check. In step S5, for example, when the key portion 11a of the key 11 is inserted into a key hole (not shown), the lock insertion detecting portion 11c comes into contact with the lock and is pressed toward the holder portion 11b of the key 11. . Thus, when the key insertion detection unit 101 detects the movement of the lock insertion detection unit 11c and outputs a signal indicating that the key 11 is inserted into the keyhole, the key insertion detection unit 101 Recognize insertion. In addition, if the key part 11a of the key 11 is not inserted into a key hole (not shown), a signal indicating that the key 11 is inserted into the key hole will not be output, so the key insertion detection unit 101 is inserted. Recognizing that no signal indicating that is output.

  In step S6, the insertion recognition unit 105a performs chattering prevention processing, and confirms whether or not the key 11 is securely inserted into the keyhole. Here, chattering prevention processing means that the insertion confirmation unit 105a reads a signal from the key insertion detection unit 101 at a predetermined time interval (for example, about 2 ms), and continues for a predetermined number of times (for example, 3 times), This is a process for determining whether or not the key 11 is securely inserted depending on whether or not a signal indicating that the key 11 is inserted into the keyhole is output. That is, when the key insertion detection unit 11c is pressed against another object even though it is not inserted into the keyhole, the key insertion detection unit 101 causes the key insertion detection unit 101 to It is conceivable that the movement of the jam detection unit 11c is detected and a signal indicating that the key 11 is inserted into the keyhole is output. Generally, this signal is generated as an instantaneous pulse chattering signal. When the insertion recognition unit 105a determines whether or not the chattering signal is inserted, the key 11 is inserted into the keyhole. In spite of the absence, there is a risk of misrecognizing it as being inserted. Normally, when the key 11 is inserted into the keyhole, the key insertion detection unit 11c is considered to be pressed for a predetermined time or more. Therefore, the chattering prevention process determines whether or not the signal from the key insertion detection unit 101 is a chattering signal based on whether or not the signal from the key insertion detection unit 101 is continuously output for a certain period. Although it is not inserted, it is prevented that it is mistakenly recognized as being inserted.

  In step S7, the insertion recognition unit 105a determines whether or not it has been determined that the key 11 has been securely inserted into the keyhole by the chattering prevention process. In step S7, for example, when it is determined that the key 11 is inserted into the keyhole, the process proceeds to step S8.

  In step S <b> 8, the state recognition unit 105 b acquires acceleration information in the XYZ axis directions supplied from the acceleration sensor 102.

  In step S <b> 9, the state recognition unit 105 b acquires information on the displacement in the XYZ axis directions with respect to the geomagnetism supplied from the magnetic sensor 103.

  In step S10, the state recognizing unit 105b recognizes the operation state of the key 11 based on the acceleration in the XYZ-axis direction and information on the displacement in the XYZ-axis direction with respect to geomagnetism. More specifically, an insertion posture indicating that the key 11 is still inserted into the keyhole based on the acceleration in the XYZ axis direction and information on the displacement in the XYZ axis direction with respect to geomagnetism, rotated to the right The operation state of either the right rotation indicating that the rotation has been performed or the left rotation indicating that the rotation has been performed to the left is recognized.

  In step S <b> 11, the control unit 105 controls the AP communication unit 107 to start communication with all the APs 13 existing in a communicable range.

  In step S <b> 12, the control unit 105 determines whether the AP communication unit 107 has a communicable AP 13 and can communicate with the AP 13. In step S12, for example, when there is an AP 13 with which the AP communication unit 107 can communicate and communication with the AP 13 is possible, the process proceeds to step S13.

  In step S13, the control unit 105 controls the AP communication unit 107 to detect the insertion state information recognized by the insertion recognition unit 105a, the remaining battery level recognized by the remaining voltage recognition unit 105c, and the recognition. The operating state information is transmitted to the AP 13 as an operating history. Then, the process proceeds to step S18. That is, here, the operation state information transmitted as the operation history includes, for example, an insertion posture indicating that the key 11 is still inserted into the keyhole, and a right indicating that the key 11 has been rotated to the right. This is information indicating an operation state of either rotation or left rotation indicating that the rotation is to the left.

  On the other hand, in step S12, for example, when there is no AP 13 communicable by the AP communication unit 107, and there is no AP 13 in communication, the process proceeds to step S14.

  In step S14, the state recognition unit 105b controls the state confirmation unit 108 to display that a communication error has occurred. For example, when the state confirmation unit 108 includes three LEDs as shown in FIG. 4, the state recognition unit 105b controls the light emission pattern to display that a communication error has occurred. . Then, the process proceeds to step S18.

  Furthermore, when it is determined in step S3 that the remaining battery level is less than 20%, in step S15, the state recognition unit 105b recognizes that an error due to a shortage of the remaining battery level has occurred. At this time, the state recognition unit 105b controls the state confirmation unit 108 to display that an error has occurred due to a shortage of the remaining battery power. For example, when the state confirmation unit 108 includes three LEDs as shown in FIG. 4, the state recognition unit 105b controls the light emission pattern, and an error due to a shortage of the remaining battery level occurs. Is displayed. Then, the process proceeds to step S18.

  In step S7, for example, when it is determined that the key 11 is not inserted into the keyhole, the process proceeds to step S16.

  In step S16, the state recognition unit 105b recognizes an operation state indicating that the key 11 has not been inserted and is not being used.

  In step S17, the state recognizing unit 105b controls the time measuring unit 105e to read out information on the elapsed time from the timing at which the latest operation history is transmitted by the AP communication unit 107, and for a predetermined time (for example, It is determined whether or not 1 second) has elapsed. For example, if it is determined in step S17 that the predetermined time has not elapsed, the process returns to step S5. If it is determined in step S17 that the predetermined time has elapsed, the process proceeds to step S11.

  That is, when the insertion of the key 11 is detected and the use of the key 11 is permitted, the operation state at that time is transmitted as an operation history from the AP communication unit 107 to the AP 13, and the insertion of the key 11 is not detected. Even in a state where the use of the key 11 is not permitted, an operation state that the key 11 has not been used is transmitted from the AP communication unit 107 to the AP 13 as an operation history.

  In step S18, the control unit 105 controls the public line communication unit 106 and the AP communication unit 107 to request communication from the hall computer 22 via the public line 23 (FIG. 1) or the AP communication unit 107. It is then determined whether there is a request for starting communication from the key storage 21. In step S18, for example, when there is a request for starting communication via the AP communication unit 107 by the process of step S33 of FIG. 11 described later, or for example, the public line is processed by the process of step S197 of FIG. 23, if there is a request to start communication in step 23, the control unit 105 controls the public line communication unit 106 or the AP communication unit 107 to generate a transmission data with a solid identification number attached to the header portion. Data is transmitted to the hall computer 22 or the key storage 21.

  In step S20, the control unit 105 controls the public line communication unit 106 to determine whether or not position information including latitude and longitude on the earth by the GPS 104 of the key 11 has been requested from the hall computer 22 through the public line 23. judge. In step S20, for example, when position information is requested from the hall computer 22 by the process of step S199 of FIG. 17 described later, the process proceeds to step S21.

  In step S21, the control unit 105 controls the GPS 104 to acquire position information on the earth, that is, latitude and longitude based on information from a satellite (not shown).

  In step S22, the control unit 105 controls the public line communication unit 106 to transmit to the hall computer 22 through the public line in association with the position information acquired from the GPS 104. At this time, the control unit 105 attaches individual identification information for identifying itself to the header portion of the data including the position information, controls the public line communication unit 106, and transmits it to the hall computer 22 via the public line 23. To do. In step S20, if it is determined that the positional information including the latitude and longitude on the earth by the GPS 104 of the key 11 is not requested from the hall computer 22 through the public line 23, the communication request is from the key storage 21. Therefore, the processes of steps S21 and S22 are skipped.

  In step S <b> 23, the power supply control unit 121 determines whether or not the power supply is received from the key storage 21. In step S22, for example, when power is received from the key storage 21 by the processing in step S38 of FIG. 11 described later, in step S24, the power control unit 121 supplies power to the battery 54. The battery is charged, and the process returns to step S1. During this time, when receiving an inquiry about the remaining voltage of the battery 54 from the key storage 21, the power supply control unit 121 supplies information on the remaining voltage to the key storage 21.

  In step S23, for example, when the power supply is not received from the key storage 21 by the process of step S38 of FIG. 11 described later, the process of step S23 is skipped. That is, in this case, the power supply control unit 121 does not charge the battery 54.

  When the insertion of the key 11 is detected by the above processing, the operation state detected at that time is transmitted as an operation history from the AP communication unit 107 to the hall computer 22 by communication between APs 13. Further, when a predetermined time elapses from the timing when the operation history is transmitted immediately before to the hall computer 22 via the AP communication unit 107, no operation state is detected, that is, the key 11 is not used. Information shown is transmitted to the hall computer 22 through the AP communication unit 107 as an operation history. Accordingly, the public line communication unit 106 can continue to supply the operation history to the hall computer 22 at least at a predetermined time interval or when an operation state is detected. In addition, when the key 11 receives position information from the hall computer 22 via the public line 23, the GPS 104 is controlled to acquire position information including latitude and longitude information on the earth, and public line communication is performed. Position information is transmitted from the unit 106 to the hall computer 22 via the public line 23.

[Key management process by key vault]
Next, the key management process by the key storage will be described with reference to the flowchart of FIG.

  In step S31, the control unit 153 sets any unprocessed one of the key storage detection unit 31 as a processing target.

  In step S32, the control unit 153 controls the storage recognition unit 153a to determine whether or not the key 11 has been stored based on a signal output from the key storage detection unit 31 set as a processing target. To determine. In step S32, for example, when the key 11 is stored in the key storage 21, and the signal indicating that the key 11 is stored is output from the key storage detection unit 31, the storage recognition unit 153a causes the key 11 to be stored. Is recognized, the process proceeds to step S33.

  In step S <b> 33, the control unit 153 controls the communication unit 156 to request communication with the key 11.

  In step S34, the control unit 153 controls the communication unit 156 to determine whether there is a response from the key 11 and communication is possible. In step S34, when there is no response from the key 11 and communication is not possible, in step S35, the control unit 153 controls the display unit 155 to display a communication error indicating that communication is not possible. Return to S33. That is, the processes in steps S33 to S35 are repeated until communication is possible.

  In step S34, for example, when response data from the key 11 has been transmitted, information on the individual identification number attached to the header portion can be acquired, and communication is considered to be possible. The process proceeds to step S36.

  In step S36, the control unit 153 controls the display control unit 153b to display on the display unit 155 that the key 11 has been stored in the key storage detection unit 31 to be processed. Proceed to step S37. By this display, it is displayed in which key storage detector 31 the key 11 is stored.

  In step S37, the control unit 153 notifies the hall computer 22 of return information indicating that the key 11 has been returned to the key storage detection unit 31 to be processed via the input / output terminal 154. . At this time, the control unit 153 transmits information on the individual identification number of the key 11 included in the response signal to the communication start request together with information specifying the key storage detection unit 31 to be processed. With this information, the hall computer 22 can recognize which key 11 has been returned to which key storage detection unit 31.

  On the other hand, in step S32, for example, when the key 11 is not stored in the key storage 21, and the key storage detection unit 31 does not output a signal indicating that the key 11 is stored, the control unit 153 in step S38. Controls the display control unit 153b to display on the display unit 155 that the key 11 is not stored in the key storage detection unit 31 to be processed, that is, not stored.

  In step S39, the control unit 153 indicates that the key 11 stored in the key storage detection unit 31 to be processed is taken out to the hall computer 22 via the input / output terminal 154. The take-out information is notified, and the process proceeds to step S44. At this time, the control unit 153, together with information specifying the key storage detection unit 31 to be processed, is stored in the response signal to the communication start request when the key 11 is stored before being taken out. Send identification number information. With this information, the hall computer 22 can recognize which key 11 has been taken out from which key storage detection unit 31.

  In step S <b> 40, the control unit 153 controls the charge control unit 153 c so that the remaining voltage of the battery 54 with respect to the power control unit 121 of the key 11 stored in the key storage detection unit 31 to be processed by the power supply unit 151. Is requested and acquired, and whether or not charging is necessary is determined from the acquired residual voltage information. If it is determined in step S40 that charging is necessary, the process proceeds to step S41.

  In step S <b> 41, the control unit 153 controls the charge control unit 153 c to supply power to the key 11 stored in the target key storage detection unit 31 to charge the battery 54.

  In step S42, the control unit 153 controls the display control unit 153b to display information indicating that the key 11 stored in the display unit 155 is being charged, and the process proceeds to step S44.

  In step S40, when it is determined that the state of charge of the battery 54 is fully charged from the acquired remaining voltage and charging is unnecessary, in step S43, the control unit 153 controls the display control unit 153b, Information indicating that the key 11 stored in the display unit 155 is fully charged and charging is completed is displayed, and the process proceeds to step S44.

  In step S44, the control unit 153 determines whether or not there is an unprocessed key storage detection unit 31. In step S44, for example, when there is an unprocessed key storage detection unit 31, the process returns to step S31. That is, the processes of steps S31 to S44 are repeated until there is no unprocessed key storage detection unit 31. If it is determined in step S44 that there is no unprocessed key storage detection unit 31, the process proceeds to step S45.

  In step S45, the control unit 153 regards all the key storage detection units 31 as unprocessed, and the process proceeds to step S46.

  In step S46, the control unit 153 determines whether or not termination is instructed. If termination is not instructed, the processing returns to step S31, and the subsequent processing is repeated. In step S46, when the end is instructed, that is, when the end of the operation is instructed, such as when the power is turned off, the process ends.

  With the above processing, return information indicating which key 11 is stored in which key storage detection unit 31 is supplied to the hall computer 22 simply by storing the key 11 in the key storage 21. In addition, by simply taking out the key 11 from the key storage box 21, carry-out information indicating which key 11 has been taken out from which key storage detection unit 31 is supplied to the hall computer 22. As a result, when the key 11 is returned to the key storage 21 or taken out of the key storage 21, the hall computer 22 can recognize which key 11 has been returned or taken out. Become. Since the key 11 can be charged by storing it in the key storage 21, the user simply takes the key 11 out of the key storage 21 and uses it, and then stores it in the key storage detector 31. This makes it possible to manage charging without being particularly conscious of charging. In this series of processing, when the key 11 is used for locking or unlocking, authentication processing or the like is not required, so the key 11 and its lock are the same as conventional mechanical keys. Since it can be easily realized with a lock, it is possible to reduce the cost generated when the present technology is introduced.

  In the above description, communication with the key 11 and the key storage 21 has been described as an example of wireless communication such as Bluetooth. However, any method can be used as long as communication is possible. A communication terminal may be provided in the vicinity of the terminal to be communicated by wired communication.

[Key management processing by AP]
Next, the key management process by the AP 13 will be described with reference to the flowchart of FIG.

  In step S71, the control unit 171 determines whether or not the power is on, and the same processing is repeated until the power is turned on. If the power is turned on in step S71, it is determined that the power is turned on, and the process proceeds to step S72.

  In step S72, the control unit 171 displays information indicating that the power is turned on on the display unit 175.

  In step S <b> 73, the control unit 171 controls the communication unit 176 to initialize a connection AP number uniquely assigned by the hall computer 22. That is, at this time, the hall computer 22 assigns a unique connection AP number to the accessing AP 13. The control unit 171 stores the newly assigned connection AP number as a solid identification number for identifying itself, and when the control unit 171 transmits data, controls the communication unit 176 to identify this solid identification in the header portion of the data. A number (connection AP number) is attached and transmitted. In addition, the control unit 171 controls the communication unit 176, and among the transmitted data, the data in which the individual identification number (connection AP number) is attached to the header portion is data addressed to itself. Receive as a thing.

  In step S <b> 74, the control unit 171 initializes the information of the individual identification number of the key 11 that is stored in the communication unit 176 and is connected by the communication unit 176. That is, by the initialization process, all the individual identification numbers of the keys 11 that have been connected by the communication unit 176 so far are deleted.

  In step S75, the control unit 171 controls the input terminal 174 to indicate that the door or frame is opened or closed by a sensor provided on the door or frame of the gaming machines 181-1 to 181-3. Acquire machine opening / closing information. In this case, the gaming machine opening / closing information may be, for example, a 2-bit signal in which door opening detection is 1 and closing detection is 0, frame opening detection is 1 and closing detection is 0. Good.

  In step S <b> 76, the control unit 171 controls the communication unit 176 to determine whether or not communication connection with any key 11 is established. In step S76, for example, when communication connection with any key 11 is established, the process proceeds to step S77.

  In step S77, the control unit 171 controls the communication unit 176 to acquire the individual identification number of the key 11 that is currently connected for communication, and stores the individual identification number of the key 11 that is connected for communication. That is, when the communication unit 176 is connected to the key 11, the header part of the data transmitted from the communication-connected key 11 is assigned with the individual identification number of the key 11. To obtain a solid identification number.

  In step S <b> 78, the control unit 171 controls the communication unit 176 to acquire radio wave intensity information received during communication with the key 11 connected for communication. That is, since the communication unit 176 includes the radio wave intensity detection unit 176a, when the radio wave intensity used for communication with the key 11 is detected and the radio wave intensity information as the detection result is acquired, the control unit 171 Output.

  In step S79, the control unit 171 controls the communication unit 176 so that the information transmitted from the key 11 includes the operation state information as the operation history, and the operation state information is the key. It is determined whether 11 is inserted into the keyhole of the lock and is in an inserted state or information indicating that it has been rotated left and right. In step S79, for example, the information on the operating state transmitted by the processing in step S13 described above indicates that the key 11 is inserted into the keyhole of the lock and is in the inserted state or rotated left and right. If it is not information, the process proceeds to step S80.

  In step S80, the control unit 171 controls the communication unit 176 to connect the hall computer 22 with the connected AP number, the individual identification number of the key 11 that is connected for communication, the radio wave intensity in communication with the key 11, The game machine opening / closing information is transmitted, and the process proceeds to step S84. The command consisting of the connected AP number, the solid identification number of the connected key 11, the radio wave intensity in communication with the key 11, and the gaming machine opening / closing information will be referred to as a first AP command hereinafter. .

  On the other hand, in step S79, for example, the information on the operation state transmitted by the process of step S13 described above indicates that the key 11 is inserted into the keyhole of the lock and is in the inserted state or rotated to the left and right. In the case of the information indicating the process, the process proceeds to step S81.

  In step S81, the control unit 171 controls the communication unit 176 to provide information indicating that insertion and rotation of the key 11 has been detected for the hall computer 22, as well as the connected AP number and the connected key. 11, the radio wave intensity in communication with the key 11, and the gaming machine opening / closing information are transmitted, and the process proceeds to step S 84. Along with information indicating that the insertion and rotation of the key 11 has been detected, the connection AP number, the individual identification number of the key 11 connected for communication, the radio wave intensity in communication with the key 11, and the opening / closing of the gaming machine Hereinafter, the information command is referred to as a second AP command.

  On the other hand, in step S76, for example, when no communication connection is made with any key 11, the process proceeds to step S82.

  In step S82, the control unit 171 determines whether the gaming machine opening / closing information is information indicating opening of a door or a frame. In step S82, when the gaming machine opening / closing information is information indicating the opening of a door or a frame, in step S83, the control unit 171 controls the communication unit 176 to control the hall computer 22 to identify the gaming machine 181. Only the game machine opening / closing information indicating that the door or the frame is open is transmitted. That is, here, since the AP 13 is not connected to the key 11 for communication, it is detected that the door or the frame of the gaming machine 181 is illegally opened without using the key 11. Note that a command consisting only of gaming machine opening / closing information indicating that the door or frame of the gaming machine 181 is in the open state is hereinafter referred to as a third AP command.

  In step S84, the control unit 171 determines whether or not the power is off. If it is determined that the power is not off, the process returns to step S75. If it is determined in step S84 that the power is off, the process ends.

  Through the above processing, the AP 13 generates the first to third AP commands based on the information from the communication-connected key 11 and transmits the first to third AP commands to the hall computer 22.

[Key management processing by hall computer]
Next, the key management process by the hall computer 22 will be described with reference to the flowchart of FIG.

  In step S101, the control unit 191 determines whether the power is on, and repeats the same processing until it is determined that the power is on. If it is determined in step S101 that the power is on, the process proceeds to step S102.

  In step S102, the control unit 191 controls the take-out number table 191a to initialize the registered information.

  In step S103, the control unit 191 controls the history time table 191b to initialize registered information.

  In step S104, the control unit 191 controls the unconnected time table 191c to initialize registered information.

  In step S105, the control unit 191 initializes a key usage number counter (not shown) for managing the number of used keys 11.

  In step S106, the control unit 191 initializes a wait timer counter of a wait timer that counts a time interval that specifies the position of the key 11 at a predetermined time interval.

  In step S <b> 107, the control unit 191 determines whether carry-out information indicating that the key 11 has been taken out from the key storage 21 has been transmitted. In step S107, for example, when it is determined that the carry-out information has been transmitted by the process of step S39 described with reference to the flowchart of FIG. 11, the process proceeds to step S108.

  In step S108, the control unit 191 reads out the individual identification number of the taken-out key 11 included in the taken-out information and registers it in the history time table 191b.

  In step S109, the control unit 191 reads the time generated by the RTC 195, and registers the individual identification number of the key 11 included in the export information in the history time table 191b in association with the export time. .

  On the other hand, in step S107, when it cannot be considered that the carry-out information has been transmitted, the process proceeds to step S110.

  In step S <b> 110, the control unit 191 determines whether return information indicating that the key 11 has been returned from the key storage 21 has been transmitted. In step S110, for example, when it is determined that the return information has been transmitted by the process of step S37 described with reference to the flowchart of FIG. 11, the process proceeds to step S111.

  In step S111, the control unit 191 reads the solid identification number of the returned key 11 included in the return information, and searches the history time table 191b for the bring-out information registered with the solid identification number.

  In step S112, the control unit 191 reads the time generated by the RTC 195, and corresponds to the take-out time of the take-out information registered in association with the individual identification number of the returned key 11 included in the return information. In addition, the return time information is registered in the history time table 191b.

  Furthermore, in step S110, when return information is not transmitted, that is, when neither take-out information nor return information is notified, the processing of steps S107 to S112 is skipped.

  When the take-out information is transmitted in this way, the individual identification number and the take-out time of the key 11 taken out are registered in the history time table 191b. Moreover, when return information is transmitted by returning the taken-out key 11, it is included in the return information among the solid identification signals registered as take-out information registered in the history time table 191b. The individual identification information is searched and the return time information is associated and registered. As a result, on the basis of the individual identification information of the key 11, information on take-out time and return time is managed in the history time table 191b.

  In step S113, the control unit 191 controls the communication unit 194 to determine whether or not the first AP command has been transmitted from the AP 13. In step S113, for example, when the first AP command is transmitted by the process of step S80 described with reference to the flowchart of FIG. 13, the process proceeds to step S114.

  In step S114, the control unit 191 registers the information on the radio wave intensity included in the first AP command in the radio wave intensity table 191e in association with the connection AP number. The radio wave intensity table 191e is, for example, a table as shown in FIG. 14, and each AP 13 is associated with each connected AP number shown on the left side in the figure, and the key (1), key ( 2), the radio wave intensity at which each key 11 communicates is shown. More specifically, FIG. 14 shows that the AP 13 identified by the AP number 0002 is communicating with the key 11 having the individual identification number of the key (1) with the radio wave intensity 30. In addition, the AP 13 with the AP number 0003 communicates with the key 11 of the individual identification number of the key (1) with the radio wave intensity 40, and communicates with the key 11 of the individual identification number of the key (2) with the radio wave intensity 30 It has been shown that Further, the AP 13 with the AP number 0004 communicates with the key 11 of the solid identification number of the key (1) with the radio wave intensity 50, and communicates with the key 11 of the solid identification number of the key (2) with the radio wave intensity 40. It has been shown that For example, the radio wave intensity in FIG. 14 is normalized by assuming that the maximum intensity of the reception level is 100 and the level at which reception is not possible is 0, but may be expressed by other methods.

  Each AP 13 is registered in association with the gaming machine 181 by the AP table 191d as shown in FIG. That is, in the AP table 191d of FIG. 15, AP13 of AP numbers 0001, 0002, 0003... Are placed at predetermined positions of the gaming machines 181 of the gaming machine numbers (unit numbers) 101, 102, 103. Is shown to be installed. As described above, since the position of the gaming machine 181 disposed in the store 1 and the installation position of the AP 13 are registered in association with each other, the information of the radio wave intensity table 191e in FIG. 11 can be understood as a distribution of the radio wave intensity transmitted from 11. For this reason, for example, the key 11 identified by the individual identification numbers of the key (1) and the key (2) from the information of the radio wave intensity table 191e in FIG. In addition, it can be estimated that it exists in a position close to the gaming machine 181 where the AP 13 with the AP number 0004 is installed.

  In step S115, the control unit 191 accesses the unconnected time table 191c, and searches for the individual identification number of the key 11 in which the radio wave intensity is registered in the radio wave intensity table 191e.

  In step S116, the control unit 191 resets the unconnected time registered with the individual identification number retrieved from the unconnected time table 191c to 0. When any of the first AP command to the third AP command is transmitted, the communication connection is established, so that the unconnected state is temporarily stopped, and the time is reset to zero.

  On the other hand, if it is determined in step S113 that the first AP command has not been transmitted, the process proceeds to step S117.

  In step S117, the control unit 191 controls the communication unit 194 to determine whether or not the second AP command has been transmitted from the hall computer 22. In step S117, for example, when the second AP command is transmitted by the process of step S81 described with reference to the flowchart of FIG. 12, the process proceeds to step S118.

  In step S118, the control unit 191 registers the information on the radio wave intensity included in the second AP command in the radio wave intensity table 191e in association with the connection AP number.

  In step S119, the control unit 191 executes an operation history storage process, and connects with the connection AP number, together with information indicating that the insertion and rotation of the key 11 included in the second AP command has been detected. The individual identification number of the key 11 and the gaming machine opening / closing information are registered in the history management table 191f. Then, the process proceeds to step S115. Here, in the state where the insertion and rotation of the key 11 are detected, the gaming machine opening / closing information includes information indicating that the door or the frame is opened. That the door or frame of the machine 181 is opened is registered in the history management table 191f. Details of the operation history storing process will be described later with reference to FIG.

  If it is determined in step S117 that the second AP command has not been transmitted from the AP 13, the process proceeds to step S120.

  In step S120, the control unit 191 controls the communication unit 194 to determine whether or not the third AP command has been transmitted from the AP 13. In step S120, for example, when the third AP command is transmitted by the process of step S83 described with reference to the flowchart of FIG. 12, the process proceeds to step S121.

  In step S121, the control unit 191 executes an operation history storage process, registers the connected AP number and gaming machine opening / closing information included in the third AP command in the history management table 191f, and the process proceeds to step S115. . Here, the key 11 is used because the information indicating that the door or the frame is opened is included in the gaming machine opening / closing information when the insertion and rotation of the key 11 are not detected. The fact that the door or the frame of the gaming machine 181 has been opened is registered in the history management table 191f. Details of the operation history storing process will be described later with reference to FIG.

  As described above, either or both of the radio wave intensity table 191e and the history management table 191f are registered by the first to third AP commands transmitted from the AP 13, and the connection communication with the AP 13 is performed. Therefore, the unconnected time registered in association with the individual identification number of the key 11 in the unconnected time table 191c is reset to zero. If it is determined in step S120 that the third AP command has not been transmitted, none of the first to third AP commands has been transmitted, so steps S114 to S116, S118, S119, And the process of S121 is skipped and a process progresses to step S122.

  In step S122, the control unit 191 executes unconnected count processing to count the unconnected time of each key 11, and for the key 11 whose counted unconnected time is longer than a predetermined time, the entrance 3 of the store 1 Therefore, it is registered in the history management table 191f.

[Unconnected count processing]
Here, the unconnected count process will be described with reference to the flowchart of FIG.

  In step S151, the control unit 191 sets any one of the keys 11 that has not been processed among the keys 11 as a processing target.

  In step S152, the control unit 191 accesses the take-out number table 191a, searches for information on the individual identification number corresponding to the processing target key 11, and based on the search result, the processing target key 11 stores the key. It is determined whether or not it is in a state of being taken out from the warehouse 21. In step S152, for example, if it is determined that the key 11 to be processed has been taken out from the key storage 21, the process proceeds to step S153.

  In step S153, the control unit 191 controls the unconnected time table 191c to count the unconnected time registered in association with the key 11 to be processed by incrementing by one. In step S152, if the key 11 to be processed has not been taken out, the process in step S153 is skipped, and the process proceeds to step S154.

  In step S154, the control unit 191 associates with the individual identification number of the key 11 to be processed, and the unconnected time registered in the unconnected time table 191c is longer than a predetermined time. Determine if it is a timeout. In step S154, for example, when the non-connection time is longer than the predetermined time and is a non-connection time-out, the process proceeds to step S155.

  In step S155, the control unit 191 executes an operation history storage process, and stores in the history management table 191f as a history that there is a possibility that the key 11 to be processed has been taken out of the store 1. The position information of the key 11 is acquired via the public line 23. The operation history saving process will be described later with reference to the flowchart of FIG.

  On the other hand, in step S154, the unconnected time registered in the unconnected time table 191c in association with the individual identification number of the key 11 to be processed is not longer than the predetermined time and is not a connection timeout. If it is considered, the process of step S155 is skipped. In step S154, if the key 11 to be processed is not taken out from the key storage 21, it is assumed that the connection will not be timed out, and the process in step S155 is also skipped. .

  In step S156, the control unit 191 determines whether or not the unprocessed key 11 exists. If the unprocessed key 11 exists, the process returns to step S151. That is, the processes of steps S151 to S156 are repeated until there is no unprocessed key 11. If it is determined in step S156 that there is no unprocessed key 11, the process ends.

  That is, it is determined whether or not all the keys 11 are registered in the take-out number table 191a by the above processing, and the keys 11 registered to be taken out are stored in the unconnected time table 191c. If the registered unconnected time is counted and the unconnected time is longer than the predetermined time, it is considered that the key 11 cannot communicate with the AP 13, that is, taken out of the store 1. And registered in the history management table 191f.

  Now, the description returns to the flowchart of FIG.

  When the unconnected count process is performed in step S122, in step S123, the control unit 191 increments the timer counter of the wait timer 196 by 1 and counts.

  In step S124, the control unit 191 determines whether or not the timer count of the wait timer 196 is greater than a predetermined threshold value. In step S124, for example, when it is determined that the timer counter of the wait timer 196 is greater than a predetermined threshold and the position of each key 11 has not been confirmed for a predetermined time or longer, the process proceeds to step S125.

  In step S125, the control unit 191 controls the position specifying unit 191g to execute the key position specifying process, and specifies the positions in the store 1 for all the keys 11. Details of the position specifying process will be described later with reference to the flowchart of FIG.

  In step S126, the control unit 191 controls the history management table 191f to execute the operation history storage process to register the position information specified by the position specifying process, or when the position cannot be specified. It identifies that it is outside the store 1, controls the position identifying unit 191g, and identifies and registers the position on the earth by the GPS 104 of the key 11 via the public line 23. Details of the operation history storing process will be described later with reference to the flowchart of FIG.

  In step S127, the control unit 191 determines whether or not the power is turned off. If the power is not turned off, the process returns to step S107. That is, the processes in steps S107 to S127 are repeated until the power is turned off. If the power is turned off in step S127, the process ends.

  Through the above processing, the hall computer 22 manages the take-out number table 191a and the history time table 191b based on the take-out information and return information of the key 11 from the key storage 21, and also the first AP from the AP 13. The radio wave intensity table 191e and the history management table 191f are managed by any one of the command to the third AP command. The hall computer 22 manages the unconnected time table 191c at predetermined time intervals. Further, the hall computer 22 manages the history management table 191f by the operation history saving process.

[Operation history saving process]
Next, the operation history storing process will be described with reference to the flowchart of FIG.

  In step S171, in the history management table 191f, the information supplied from the AP 13 is the second AP command, that is, when the use of the key 11 is detected, the opening of the door or the frame is detected from the gaming machine 181. It is determined whether or not the information is information when a normal release indicating that this is detected. In step S171, for example, as shown in step S119 of FIG. 13, when the information is considered to be information when a normal release is detected, the process proceeds to step S172.

  In step S172, in the history management table 191f, the information included in the second AP command is information indicating that the insertion and rotation of the key 11 has been detected, and the gaming machine opening / closing information indicates that the door or frame is opened. It is determined whether it is the information to show. When it is determined that the information included in the second AP command is information indicating that the insertion and rotation of the key 11 has been detected, and the gaming machine opening / closing information is information indicating opening of a door or a frame, The process proceeds to step S173.

  In step S173, the history management table 191f stores the date information in the table based on the date information generated by the RTC 195.

  In step S174, the history management table 191f stores the individual identification number of the communication-connected key 11 included in the second AP command in the table.

  In step S175, the history management table 191f specifies the position of the AP 13 corresponding to the gaming machine 181 in which the key 11 is used, based on the connection AP number included in the second AP command. That is, since the key 11 having the same individual identification number may communicate with a plurality of APs 13, there may be a plurality of APs communicating with the key 11 having the same individual identification number. In such a case, a plurality of second AP commands are supplied. Therefore, the history management table 191f refers to the radio wave intensity table 191e and the like, and exists in each of the second AP commands from the plurality of APs 13 that may be communicating with the key 11 having the same individual identification number. Among the connected AP numbers, the AP 13 having the strongest radio wave intensity is specified as the AP 13 using the key 11.

  In step S176, the history management table 191f searches the AP table 191d for a gaming machine number corresponding to the identified AP 13 connection AP number, and in step S177 registers the gaming machine number (unit number) in the table. .

  In step S178, the history management table 191f registers an opening indicating opening of a door or a frame, which is gaming machine opening / closing information, in the table.

  As a result, for example, the history management table 191f registers information as shown at the top of FIG. That is, in the first row of the history management table 191f in FIG. 18, the date, position, key identification number, and state are set from the left, and in the second row, February 21, 2011 is set. At 13:10, an operation history indicating that the door or frame of the gaming machine 181 with the machine number 102 has been opened with the key 11 with the solid identification number 3 is registered.

  On the other hand, in step S172, the information included in the second AP command is information indicating that the insertion and rotation of the key 11 are detected, and the gaming machine opening / closing information is not information indicating the opening of the door or the frame. If determined to be, the process proceeds to step S179.

  In step S179, in the history management table 191f, the information included in the second AP command is information indicating that the insertion of the key 11 is detected but the rotation is not detected, and the gaming machine opening / closing information is the door. Or whether it is information indicating the closing of the frame. In step S179, for example, the information included in the second AP command is information indicating that the insertion of the key 11 is detected but the rotation is not detected, and the opening / closing information of the gaming machine is the door or frame. If it is determined that the information indicates closure, the process proceeds to step S180.

  In step S180, the history management table 191f stores the date information in the table based on the date information generated by the RTC 195.

  In step S181, the history management table 191f stores in the table the individual identification number of the key 11 connected for communication, which is included in the second AP command.

  In step S182, the history management table 191f specifies the position of the nearest AP 13 of the key 11 based on the connection AP number included in the second AP command.

  In step S183, the history management table 191f searches the AP table 191d for a gaming machine number corresponding to the identified connected AP number of the AP 13, and in step S184 registers the gaming machine number (unit number) in the table. .

  In step S185, the history management table 191f registers in the table the closing indicating the closing of the door or the frame, which is the gaming machine opening / closing information.

  As a result, for example, information such as that shown in the third row of FIG. 18 is registered in the history management table 191f. That is, in the third row of the history management table 191f in FIG. 18, the date, position, key identification number, and state are registered from the left, and in the uppermost row, 13 February 21, 2011 is registered. An operation history indicating that the door or the frame of the gaming machine 181 with the machine number 102 is closed with the key 11 with the solid identification number 3 at time 11 is registered.

  On the other hand, in step S179, for example, the information included in the second AP command is not information indicating that the insertion of the key 11 is detected but rotation is not detected, or the gaming machine opening / closing information is a door, Or when it determines with it not being information which shows the closure of a frame, a process is complete | finished.

  Furthermore, when it is determined in step S171 that the opening / closing is not normal, the process proceeds to step S186.

  In step S186, the history management table 191f indicates that the information supplied from the AP 13 is the third AP command, that is, the opening of the door or the frame is detected from the gaming machine 181 without using the key 11. It is determined whether or not the information is information when an unauthorized release indicating is detected. In step S186, for example, as shown in step S121 of FIG. 13, when the information is regarded as information when unauthorized opening is detected, the process proceeds to step S187.

  In step S187, the history management table 191f stores the date / time information in the table based on the date / time information generated by the RTC 195.

  In step S188, the history management table 191f specifies the position of the AP 13 based on the connected AP number included in the third AP command. In this case, since the gaming machine 181 notifies the AP 13 of the opening of the door or the frame, the AP 13 that has received this notification is specified.

  In step S189, the history management table 191f searches the AP table 191d for a gaming machine number corresponding to the identified connected AP number of the AP 13, and in step S190, registers the gaming machine number (unit number) in the table. .

  In step S191, the history management table 191f registers opening (unauthorized) indicating unauthorized opening of a door or a frame as gaming machine opening / closing information in the table.

  As a result, for example, information as shown in the fourth row of FIG. 18 is registered in the history management table 191f. That is, in the fourth row of the history management table 191f in FIG. 18, an operation indicating that the door or frame of the gaming machine 181 with the machine number 102 has been illegally opened at 13:11 on February 21, 2011. History is registered.

  On the other hand, if it is determined in step S186 that the opening / closing is not unauthorized, the process proceeds to step S192.

  In step S192, the control unit 191 determines whether or not the process is after the position of the key 11 is specified by the key position specifying process described later with reference to FIG. In step S192, for example, when the key position specifying process is performed by the process of the previous step S125 as in the process of step S126 in the flowchart of FIG. 13, the process proceeds to step S193.

  In step S193, the history management table 191f stores the date / time information in the table based on the date / time information generated by the RTC 195.

  In step S194, the history management table 191f searches for the corresponding gaming machine number based on the connection AP number obtained in the immediately preceding process, and in step S195, registers the gaming machine number (unit number) in the table. To do.

  As a result, for example, information as shown in the sixth row of FIG. 18 is registered in the history management table 191f. That is, in the sixth row of the history management table 191f of FIG. 18, the key 11 having the identification number 4 is detected near the gaming machine 181 with the unit number 103 at 12:10 on February 21, 2011. An operation history indicating that is registered. Thus, the position of the key 11 is registered in units of a predetermined time measured by the wait timer 196. Thus, by registering the position of the key 11 at predetermined time intervals, a flow line display described later becomes possible.

  Furthermore, in step S192, if the key position has not been obtained by the immediately preceding process, that is, neither normal release, unauthorized release, or key position detection has been performed, the key position specifying process specifies the key 11 position. It is considered that the key 11 cannot be taken out of the store 1. As described above, when it is determined in step S192 that the key position has not been obtained by the immediately preceding process, that is, it has been taken out of the store 1, the process proceeds to step S196.

  In step S196, the history management table 191f stores the date / time information in the table based on the date / time information generated by the RTC 195.

  In step S197, the history management table 191f controls the public line communication unit 198 to change the public line 23 based on the number registered in advance in association with the individual identification number of the key 11 whose position could not be specified. To make a communication connection request.

  In step S198, the history management table 191f controls the public line communication unit 198 to communicate with the key 11 specified by the individual identification number of the key 11 whose position could not be specified via the public line 23. It is determined whether or not there is. If communication via the public line 23 is not possible in step S198, the process ends. In step S198, if there is a response by the process of step S19 described with reference to the flowchart of FIG. 10 and communication becomes possible, the process proceeds to step S199.

  In step S <b> 199, the public line communication unit 198 requests position information that can be acquired by the GPS 104 from the key 11 that is connected for communication via the public line 23.

  In response to the request for position information in step S199, for example, when the position information by GPS is transmitted by the process of step S22 in the flowchart of FIG. 10, the public line communication unit 198 has been transmitted in step S200. Get location information. The history management table 191f registers the acquired position information in the table in association with the solid identification information for identifying the key 11.

  In step S201, the history management table 191f registers in the table a take-out indicating that the key 11 has been taken out of the store 1.

  As a result, for example, information as shown in the fifth row of FIG. 18 is registered in the history management table 191f. That is, in the fifth row of the history management table 191f in FIG. 18, a key having a solid identification number of 5 at a position of 35 degrees 42 minutes north latitude and 139 degrees 40 minutes east longitude at 14:00 on February 21, 2011. An operation history indicating that 11 is detected in a state of being taken out to a position outside the store 1 is registered.

  Through the above processing, the position where the key 11 was used at the timing when the normal release of the gaming machine 181 was detected, that is, the operation history of which gaming machine 181 in the store 1 was used is associated with the date and time. It can be accumulated in the history management table 191f. In addition, when an unauthorized release is detected, the position of the gaming machine 181 where the unauthorized release is detected can be identified and registered in the history management table 191f in association with the date and time. Furthermore, the position of the gaming machine 181 where the key 11 is detected at predetermined time intervals can be registered in association with the date and time. Even if the key 11 is taken out of the store 1, it is registered that the key 11 has been taken out, and at which position on the earth it is registered via the public line 23. As a result, even if the key 11 is taken out of the store 1, the key 11 can be traced.

[Key position identification processing by hall computer in FIG. 9]
Next, the key position specifying process, which is the process of step S125 in the flowchart of FIG. 13, by the hall computer 22 of FIG. 9 will be described with reference to the flowchart of FIG.

  In step S221, the position specifying unit 191g sets the unprocessed key 11 whose position is to be specified as a processing target.

  In step S222, the position specifying unit 191g specifies the AP 13 to be processed.

  In step S223, the position specifying unit 191g accesses the radio wave intensity table 191e and reads out the radio wave intensity with the AP 13 to be processed in the communication connection with the key 11 to be processed.

  In step S224, the position specifying unit 191g determines whether or not the read radio wave intensity is higher than a predetermined threshold value. The predetermined threshold here is, for example, a value indicating that the key 11 is sufficiently close to the AP 13. Therefore, when the radio field intensity is higher than a predetermined threshold, the key 11 is present at a position sufficiently close to the AP 13, that is, it can be regarded as existing near the gaming machine 181 specified by the AP 13.

  If it is determined in step S224 that the radio wave intensity is lower than the predetermined threshold and the key 11 to be processed does not exist near the AP 13 to be processed, the process proceeds to step S225.

  In step S225, the position specifying unit 191g determines whether or not there is an unprocessed AP 13. If there is an unprocessed AP 13, the process returns to step S222. That is, the processes in steps S222 to S225 are repeated until there is no unprocessed AP 13.

  At this time, if it is determined in step S224 that the radio wave intensity is higher than a predetermined threshold, that is, the key 11 to be processed is located near the gaming machine 181 installed in association with the AP 13 to be processed. If it is determined that the data exists in step S227, the process proceeds to step S227. In step S227, the position specifying unit 191g considers that the key 11 to be processed exists in the vicinity of the AP 13 to be processed, specifies the position of the AP 13 as the position where the key 11 exists, The process proceeds to step S228.

  If it is determined in step S225 that there is no unprocessed AP 13, the position specifying unit 191g cannot specify the position of the key 11 to be processed in step S226, that is, outside the store 1. Considered to be taken out.

  In step S228, the position specifying unit 191g determines whether or not there is an unprocessed key 11 to be processed. If there is an unprocessed key 11, the process returns to step S221. On the other hand, if it is determined in step S228 that there is no unprocessed key 11, the process ends.

  That is, by the above processing, each key 11 is set as a processing target, and the radio wave intensity with each AP 13 connected for communication is compared with a predetermined threshold value, which is higher than the predetermined threshold value, that is, from a predetermined distance. When an AP 13 that is considered to be close is detected, the AP 13 can be set as the position of the key 11 to be processed. In the above description, when an AP 13 communicating with a radio wave intensity higher than a predetermined threshold is detected, the position of the AP 13 is set to the position of the key 11. However, as the radio wave intensity increases, the key 11 Therefore, the AP 13 having the highest radio wave strength among the radio wave strengths of all the APs 13 connected to the key 11 is set as the key 11 position. It may be.

[Key management process in key management system]
As described above, when the key management processing realized by the key management system including the key 11, the key storage 21, the AP 13, the hall computer 22, and the gaming machine 181 is summarized, for example, the processing shown in the flowchart of FIG. It becomes. FIG. 20 is a simple flowchart for explaining the operation of the clerk of the game store, the key storage processing of the key storage 21, the AP 13, the hall computer 22, and the gaming machine 181 from the left.

  That is, when an attendant at the game store that is the user takes out the key 11 in step S301, in step S321, the key storage 21 detects that the key 11 has been taken out by the process of step S38 in FIG. In step S322, the key storage box 21 sends out to the hall computer 22 carry-out information indicating that the key 11 has been taken out by the process in step S39 in FIG. In step S371, the hall computer 22 registers the individual identification number of the key 11 taken out in the take-out number table 191a by the process in step S108 of FIG. 13, and registers the take-out time in the history time table 191b. As a result, it is possible to manage the individual identification number of the key 11 taken out just by taking out the key 11 from the key storage 21 and the time when it was taken out.

  Further, in step S302, when a clerk at the game shop as a user takes out the key 11 and moves, the predetermined time has passed and the user exists at the point A. In step S311, the key 11 is changed to the step of FIG. The operation history is notified to the AP 13 by the process of S13. In step S341, the AP 13 recognizes the communication connection with the key 11 by the process in step S76 of FIG. Further, if key insertion and rotation are not detected, in step S342, the AP 13 transmits the first AP command to the hall computer 22 by the process of step S80 of FIG. By this process, in step S372, the hall computer 22 registers the radio wave intensity in the radio wave intensity table 191e by the process of step S114 of FIG. 13, thereby specifying the position of the key 11 in step S125, and the process of step S126. Is registered in the history management table 191f. As a result, the position of the key 11 can be registered as a history at predetermined time intervals, and the flow line of the user of the key 11 can be recorded.

  Further, in step S303, when a clerk at the game shop as a user takes out the key 11, and inserts the key 11 into the keyhole of the lock and rotates, in step S312, the key 11 is changed to steps S6 to S10 in FIG. Insertion and rotation are detected by the processing, and information on the operating state is transmitted to the AP 13. In response to this, in step S343, the AP 13 detects information including information on insertion and rotation detection of the key 11 by the process in step S79 of FIG.

  Further, following the operation of step S303, when an attendant at the game store that is the user operates the key 11 to open the door or the frame of the gaming machine 181 in step S304, in step S391, the gaming machine 181 Detects opening of a door or frame. In step S392, the gaming machine 181 notifies the AP 13 of the opening of the door or frame. In step S344, the AP 13 obtains a notification indicating that the door or frame is opened from the gaming machine 181 in step S75 of FIG. In response to this, in step S345, the AP 13 transmits a second AP command including information indicating insertion and rotation detection to the hall computer 22 by the process of step S81 of FIG. In step S373, the hall computer 22 registers the radio wave intensity information as position information in the radio wave intensity table 191e by the process of step S118 in FIG. 13, and registers the operation history in the history management table 191f by the process of step S119. Here, since the insertion and rotation information of the opening of the door or the frame of the gaming machine 181 is included after the insertion and rotation of the key 11 is detected, the opening of the door or the frame is normally opened. Is considered to be. As a result, a normal door or frame opening operation by the operation of the key 11 can be recorded as a history.

  In addition, in step S305, when the attendant at the game store that is the user takes the key 11 out of the store 1 and becomes unable to communicate with any of the APs 13, in step S374, the hall computer 22 A timeout of the unconnected time is detected by the process of step S154, and the takeout of the key 11 outside the store 1 is detected and registered in the history management table 191f in step S375. As a result, it is possible to detect the key 11 being taken out of the store, and by requesting and acquiring the location information by GPS from the public line 23 to the key 11, even outside the store, It is possible to check and register where it exists on the earth.

  Furthermore, in step S306, if a staff member of the game store or a third party illegally opens the door or the frame of the gaming machine 181 without using the key 11, the gaming machine 181 is used in step S393. Detects the opening of a door or frame. In step S394, the gaming machine 181 notifies the AP 13 of the opening of the door or frame. In step S346, the AP 13 acquires a notification indicating that the door or the frame is opened from the gaming machine 181 in step S75 of FIG. In response to this, in step S347, the AP 13 transmits a third AP command to the hall computer 22 by the process of step S83 in FIG. In step S376, the hall computer 22 registers the operation history in the history management table 191f by the process in step S121 of FIG. Here, since the insertion and rotation of the key 11 is not detected, and the opening / closing information of the gaming machine 181 indicating the opening of the door or the frame is included, the opening of the door or the frame is illegal. Considered to be open. As a result, it is possible to detect an unauthorized door or frame opening, and it is possible to register an unauthorized door or frame opening as a history.

  In addition, in step S307, when a clerk at the game store as a user returns the key 11 to the key storage 21, the key storage 21 returns the key 11 by the process of step S36 in FIG. 11 in step S323. Detect that. In step S324, the key storage 21 sends return information indicating that the key 11 has been returned by the process in step S37 of FIG. In step S377, the hall computer 22 erases the individual identification number of the returned key 11 registered in the take-out number table 191a by the process in step S112 of FIG. 13, and also returns the return time to the history time table 191b. sign up. As a result, the return of the key 11 can be managed.

  With the above processing, it is possible to manage the taking out and returning of the key 11. Further, it is possible to manage the time when the key 11 is taken out and the time when it is returned. Furthermore, the history management table 191f can manage information on the operation state of the key 11 as time information together with information on the opening / closing states of the doors and frames of the gaming machine and operation history together with the position thereof. In addition, since the opening and closing of the door or frame of the gaming machine 181 can be managed together with the insertion and rotation of the key 11, an unauthorized opening such as opening the door or the frame without using the key 11 is recognized. It becomes possible. Furthermore, if the positional relationship between the AP 13 and the gaming machine 181 is known by managing the radio wave intensity table 191e related to the communication between the key 11 and the AP 13, the lock of which gaming machine 181 is locked based on the radio wave intensity. It is possible to recognize whether the key 11 has been operated by being inserted into the key.

[Flow history display processing]
Next, the flow line history display process will be described with reference to the flowchart of FIG.

  In step S281, the control unit 191 determines whether or not display of the flow line history is instructed by operating the operation unit 199, and repeats the same processing until the display of the flow line history is instructed. . In step S281, when the display of the flow line history is instructed, the process proceeds to step S282.

  In step S282, the control unit 191 controls the flow line history display control unit 191h to generate an image for requesting input of information specifying the key 11, and causes the display unit 193 to display the image.

  In step S283, the flow line history display control unit 191h determines whether or not the operation unit 199 has been operated to input information for specifying the key 11 on which the flow line history is to be displayed. Returns to step S282. That is, the processes in steps S282 and S283 are repeated until information specifying the key 11 is input. In step S283, for example, when information for specifying the key 11 is input, the process proceeds to step S284.

  In step S284, the flow line history display control unit 191h accesses the history management table 191f, and information indicating the position in the operation history with the solid identification number that identifies the key 11 on which the flow line history is to be displayed, and the state Extract information in time series. That is, for example, when the history management table 191f as shown in FIG. 18 is registered, information on the gaming machine number (unit number) is extracted as information corresponding to the position information.

  In step S285, the flow line history display control unit 191h connects the extracted position information in time series to generate a flow line history image.

  In step S286, the flow line history display control unit 191h displays, for example, the flow line history image generated as illustrated in FIG.

  That is, in the flow line history image 211 of FIG. 22, gaming machine images 222-1 to 222-6 corresponding to the gaming machine 181 are displayed, and are indicated by dotted lines in the figure as the movement lines of the key 11. A flow line 221 is displayed. A key position 221a that is the position of the key 11 is displayed at the head of the flow line 221, and the flow line of the key 11 can be displayed by such display. As a result, by displaying the flow line history, it is visually recognized what flow line the clerk who had the designated key 11 was moving in the state of having the key 11. It becomes possible.

  In step S287, the flow line history display control unit 191h displays state information in time series of the key 11 for which display of the flow line history is requested. This display may be the same display as the history management table 191f of FIG. Note that this state information may be displayed separately as a pop-up window on the flow line history image 211, or may be displayed simultaneously on a window displaying the flow line history image 211 and another window. Also good.

  In step S288, the control unit 191 determines whether or not the operation unit 199 has been operated to instruct the end of display. If the end has not been instructed, the process returns to step S286. That is, until the end is instructed, the processes in steps S286 and S287 are repeated, and the flow line history and state information for the key 11 instructed to be displayed continue to be displayed. If an end instruction is given in step S288, the process ends.

  Through the above processing, the flow line history of the key 11 can be displayed based on the operation history registered in the history management table 191f based on the information specifying the key 11. As a result, it becomes possible to grasp how the clerk has moved in the store 1 individually in units of keys 11. At this time, since the state information is also displayed, it is possible to grasp at what timing on the flow line the operation state has been reached.

<2. Modification>
[Modification of Hall computer]
In the above, when the position of the key 11 is specified, the radio wave intensity in communication with the processing target AP 13 with respect to the processing target key 11 is sequentially compared with a predetermined threshold, and the AP 13 higher than the predetermined threshold is first Although the example in which the position is specified by the gaming machine number (unit number) of the gaming machine 181 installed in association with the detected AP 13 has been described, the minimum unit of the position is the gaming machine 181. Therefore, a plurality of APs 13 communicating with a radio wave intensity higher than a predetermined threshold may be obtained, and the barycentric position corresponding to the radio wave intensity may be set as the key 11 position.

  FIG. 23 shows a modification of the configuration example of the hall computer 22 in which the position of the key 11 can be obtained with higher accuracy. In addition, about the structure provided with the same function as Hall computer 22 of FIG. 9, the same code | symbol is attached | subjected and the description shall be abbreviate | omitted suitably. That is, the hall computer 22 in FIG. 23 differs from the hall computer 22 in FIG. 9 in that a location specifying unit 231 is provided instead of the location specifying unit 191g.

  That is, the position specifying unit 231 has basically the same function as the position specifying unit 191g, but the game machine can be used to specify the position of the key 11 with one AP 13 by the position specifying unit 191g. Whereas the position 181 is obtained as a minimum unit, the position specifying unit 231 is different in that the position specifying unit 231 uses a plurality of APs 13 to obtain the position of the center of gravity according to each radio wave intensity.

[Key position identification processing by hall computer in FIG. 23]
Here, the key position specifying process by the hall computer 22 of FIG. 23 will be described with reference to the flowchart of FIG.

  In step S251, the position specifying unit 231 sets one of the unprocessed keys 11 as the processing target key 11 whose position is to be specified.

  In step S252, the position specifying unit 231 specifies one of the unprocessed APs 13 to be processed.

  In step S253, the position specifying unit 231 accesses the radio wave intensity table 191e, and reads the radio wave intensity with the AP 13 to be processed in the communication connection with the key 11 to be processed.

  In step S254, the position specifying unit 231 determines whether or not the read radio wave intensity is higher than a predetermined threshold value. The predetermined threshold here is, for example, a value indicating that the key 11 is sufficiently close to the AP 13.

  If it is determined in step S254 that the radio wave intensity is higher than the predetermined threshold, that is, the key 11 to be processed exists near the gaming machine 181 installed in association with the AP 13 to be processed. If so, the process proceeds to step S255. In step S255, the position specifying unit 231 stores the AP 13 that is the processing target as a candidate AP.

  In step S256, the position specifying unit 231 determines whether or not there are three or more candidate APs. In step S256, for example, when there are not three candidate APs, the process proceeds to step S257.

  In step S257, the position specifying unit 231 determines whether or not there is an unprocessed AP 13. If there is an unprocessed AP 13, the process returns to step S252. In step S254, when the radio wave intensity is lower than the predetermined threshold value, the process of step S255 is skipped. That is, the processes in steps S252 to S257 are repeated until three candidate APs are detected or there is no unprocessed AP13.

  For example, when there are three or more candidate APs in step S256, in step S260, the position specifying unit 231 calculates the position of the key 11 based on the information on the radio field intensity of the candidate AP. The gaming machine number of the gaming machine 181 corresponding to the selected position is set as the key 11 position.

  More specifically, the position specifying unit 231 calculates the position of the key 11 by the following method. Here, as shown in FIG. 25, it is assumed that the position of the AP 13 is required to be an accurate position in the store 1. In FIG. 25, coordinates are set by drawing lines in the store 1 in a horizontal pattern and a vertical direction at equal intervals in a grid pattern. In FIG. 25, the intervals between the lines are assumed to be 1 m in both the horizontal direction and the vertical direction. AP 13 is a gaming island formed of two rows above and below in the vertical direction at intervals of 2 m in the horizontal direction, and has a spacing of 3 m in the vertical direction within each island, and the spacing between the gaming islands is 4 m. Therefore, each AP 13 can be expressed by coordinates. For example, the lower left AP can be expressed as coordinates AP (2, 2) (= (horizontal coordinates, vertical coordinates)), and the coordinates of each AP 13 in the bottom row are , AP (2, 2), AP (4, 2), AP (6, 2),... The coordinates of AP13 in the leftmost column are AP (2, 2), AP (2, 5), AP (2, 9), AP (2, 12) in order from the bottom. In addition, the number displayed in the dotted line of the legal shape in association with the AP 13 indicates the machine number of the gaming machine 181 on which the AP 13 is installed. Therefore, in FIG. 25, the lowest number is 101, 102, 103, 104,... From the left, and the leftmost column is 101, 201,. .

  The information shown in FIG. 25 is associated with the individual identification number of each AP 13 in advance and stored in a memory (not shown) or the like by the position specifying unit 231 as a table shown in FIG. 26, for example. That is, in FIG. 26, from the left, the individual identification number of the AP 13, the horizontal coordinate in the store of the corresponding AP, and the vertical coordinate in the store of the corresponding AP are registered. Therefore, in FIG. 26, the coordinates of AP13 with the identification number 0001 are registered as AP (n_0001, m_0001), and the coordinates of AP13 with the identification number 0002 are registered as AP (n_0002, m_0002). The coordinates of AP13 with a solid identification number 0003 are registered as AP (n_0003, m_0003), and the coordinates of AP13 with a solid identification number 0004 are registered as AP (n_0004, m_0004). Here, in the notation in the specification, the notation after “_” indicates the subscript in the figure, and the same applies hereinafter.

  For example, as shown in the left part of FIG. 27, the radio wave intensity of the AP 13 specified by the solid identification numbers 0004, 0003, 0002 is 50, 40, 30 in order, When three APs 13 are extracted, the position specifying unit 231 converts the coordinates to the center-of-gravity calculation coordinates of each AP 13, for example, as illustrated in the right part of FIG. 27. That is, here, the position of the AP 13 with the solid identification number 0004 having the highest radio wave intensity is set as the origin, and the AP 13 with the solid identification numbers 0005 and 0006 has coordinates (X_a + 2) with the AP 13 with the solid identification number 0004 as the origin. , Y_a + 2), (X_a + 1, Y_a + 1).

  The position specifying unit 231 calculates the following equation (1), for example, to calculate, as the position of the key 11, the position k that is the center of gravity position where these coordinates have the relationship shown in FIG. 28. .

  In Equation (1), a is a coefficient for the rank of the radio wave intensity, E is the radio wave intensity at each coordinate, and K (x, y) is the barycentric position. In the calculation, the count a is 0. In FIG. 28, it is shown that the center-of-gravity position k obtained for each position of AP (a), AP (a + 1), AP (a + 2) is the position of the key 11.

  That is, the position specifying unit 231 calculates the coordinates of the AP 13 having a radio wave intensity higher than a predetermined threshold and the barycentric position weighted by the radio wave intensity as the position where the key 11 exists. The position of the key 11 thus determined is determined regardless of the position of the AP 13, that is, the position of the gaming machine 181. However, since it is necessary information about which gaming machine 181 the key 11 is used in, it is necessary to specify which gaming machine 181 was used in the range of the position required as the position of the key 11. Therefore, for example, the position specifying unit 231 stores a table as shown in FIG. 29 in a memory (not shown), and sets the position where each gaming machine 181 exists as an area for each gaming machine 181. The gaming machine 181 in which the key 11 is used can be specified.

  In FIG. 29, from the left, a gaming machine number (unit number), a horizontal area range of the gaming machine with that gaming machine number, and a vertical area range are set. That is, in FIG. 29, the gaming machine 181 with gaming machine number 101 has horizontal areas 1 to 3 and the vertical area 1 to 3, and gaming machine 181 with gaming machine number 102 has a horizontal area. The area in the direction is n_102a to n_102a + 2, the area in the vertical direction is m_102a to m_102a + 2, and the gaming machine 181 with the gaming machine number 103 is n_103a to n_103a + 2 in the horizontal direction and m_103a to m_103a + 2 in the vertical direction. ing. Therefore, the gaming machine 181 in which the key 11 is used is specified based on which range the key 11 is specified in this way.

  Now, the description returns to the flowchart of FIG.

  If it is determined in step S257 that there is no unprocessed AP 13, the position specifying unit 231 determines whether there is a candidate AP in step S258. In step S258, for example, when there is a candidate AP, the process proceeds to step S259.

  In step S259, the position specifying unit 231 obtains the position of the key 11 from the coordinates of the candidate AP according to the number of candidate APs. That is, when the number of candidate APs is one, the position specifying unit 231 outputs the gaming machine number of the gaming machine 181 specified by the position using the coordinates of the one AP 13 as the position of the key 11. To do. When there are two candidate APs, the position specifying unit 231 uses the inner dividing point based on the ratio of the radio wave intensity of the coordinates between the two APs 13 as the key 11 position, and identifies the gaming machine at the key 11 position. The game machine number 181 is output as the position. If the number of candidate APs is three or more, the position of the center of gravity is obtained, so the number of candidate APs considered here is one or two.

  On the other hand, if no candidate AP exists in step S258, the process proceeds to step S261.

  In step S261, the position specifying unit 231 determines that the position of the key 11 cannot be specified, that is, that communication is not possible, and the process ends.

  That is, by the above processing, each key 11 is set as a processing target, and the radio wave intensity with each AP 13 connected for communication is compared with a predetermined threshold value, which is higher than the predetermined threshold value, that is, from a predetermined distance. When the three APs 13 that are considered to be close to each other are detected, the weighted center of gravity position based on the radio field strength is obtained as the position of the key 11, and the used gaming machine 181 is specified based on the position. Therefore, it becomes possible to specify the gaming machine 181 in which the key 11 is used with higher accuracy. In the above description, an example has been described in which the position of the center of gravity is obtained when three radio wave intensities exceeding the threshold value are detected. However, it is considered that the stronger radio wave intensity is closer to the key 11. It is also possible to obtain the center of gravity by extracting only the top three points of the AP 13 having high strength.

<3. Second Embodiment>
[Other key configuration examples]
In the above description, an example in which the current position is inquired from the hall computer 22 to the key 11 via the public line 23 when the communication between the key 11 and the AP 13 cannot be performed for a time longer than a predetermined time has been described. Further, when communication is not possible for a time longer than a predetermined time, the key 11 communicates with the hall computer 22 via the public line 23, and when this communication is established, the hall computer 22 inquires about the current position. You may do it.

  FIG. 30 shows a configuration example of the key 11 configured to communicate with the hall computer 22 via the public line 23 when communication between the AP 13 and the AP communication unit 107 becomes impossible for a longer time than the predetermined time. In the configuration of the key 11 in FIG. 30, the same reference numerals are given to configurations having the same functions as the configuration in the key 11 in FIG. 5, and description thereof will be omitted as appropriate.

  30 is different from the configuration of the key 11 in FIG. 5 in that a control unit 305 is provided instead of the control unit 105. In addition to the configuration of the control unit 105, the control unit 305 also includes a time storage unit 305a and an unconnected time determination unit 305b. Each time the time storage unit 305a communicates with the AP 13 via the AP communication unit 107, the time storage unit 305a reads the count value of the timer 109 and stores it as a transmission time. When the unconnected time determined from the difference between the count value of the timer 109 stored in the time storage unit 305a and the current count value of the timer 109 is longer than a predetermined time, the unconnected time determination unit 305b Then, it is determined that it is time to communicate with the hall computer 22 via the public line 23.

[Other hall computer configuration examples]
Next, a configuration example of the hall computer 22 that requests the current position from the key 11 through the public line 23 corresponding to the key 11 in FIG. 30 will be described with reference to FIG. To do. In the configuration of the hall computer 22 in FIG. 30, if the configuration has the same function as the configuration of the hall computer 22 in FIG. 9, the configuration will be given the same reference numerals, and the description thereof will be omitted as appropriate. .

  That is, the hall computer 22 of FIG. 30 is different from the hall computer 22 of FIG. 9 in that a history management table 321 is provided instead of the history management table 191f.

  The history management table 321 has the same basic functions as the history management table 191f. However, when there is communication from the key 11 through the public line 23, the history management table 321 requests the key 11 for the current position, and the operation history. Is registered in the history management table 321.

[Key management process using the key shown in FIG. 30]
Next, the key management process using the key shown in FIG. 30 will be described with reference to the flowchart shown in FIG. In the flowchart of FIG. 32, the processing of steps S301 to S313, S315 to S319, S325, and S326 is the same as the processing of steps S1 to S24 in the flowchart of FIG. Note that the public line processing from the hall computer in step S319 is the processing in steps S18 to S22 in the flowchart of FIG.

  That is, in step S313, as in the process of step S13 in FIG. 10, when information serving as the operation history of the key 11 is transmitted to the AP 13, the control unit 305 controls the time storage unit 305a in step S314. Then, the time of communication with the AP 13 is updated and stored. That is, the time storage unit 305a stores the timer count value of the timer 109 corresponding to the latest communication time.

  Furthermore, for example, when there is no communication request from the hall computer 22 via the public line 23 in step S319 and the process of step S319 is skipped, the process proceeds to step S320.

  In step S320, the control unit 305 controls the unconnected time determination unit 305b to obtain the difference between the timer count value stored in the time storage unit 305a and the timer count value currently generated by the timer 109. It is determined whether or not the unconnected time is longer than a predetermined time. For example, when it is determined that the unconnected time is longer than the predetermined time, the process proceeds to step S321.

  In step S321, the control unit 305 controls the public line communication unit 106 to cause the hall computer 22 to request communication via the public line 23.

  In step S322, the control unit 305 controls the public line communication unit 106 to determine whether or not the current position by the GPS 104 is requested from the hall computer 22 via the public line 23. Repeat the process. In step S322, for example, when the current position by the GPS 104 is requested from the hall computer 22, the process proceeds to step S323.

  In step S323, the control unit 305 controls the GPS 104, and acquires position information including the position of the key 11 on the earth, that is, the latitude and longitude, based on a signal from a satellite (not shown).

  In step S <b> 324, the control unit 305 controls the public line communication unit 106 to transmit the position information acquired by the GPS 104 to the hall computer 22. At this time, the time storage unit 305 a stores the timer count value of the timer 109 at the timing corresponding to the time when the position information is transmitted through the public line 23. For this reason, if communication with the hall computer 22 is performed, it is considered that communication with the AP 13 is performed, and the unconnected time is reset. Even when the position information by the GPS 104 is transmitted based on the public line processing from the hall computer 22 by the process of step S319, the time stored in the time storage unit 305a may be reset. By doing so, since the unconnected time is counted from the timing when the communication via the public line 23 is successful, the communication using the public line 23 from the key 11 to the hall computer 22 can be reduced. .

  By the above processing, the key 11 is transmitted to the hall computer 22 when the non-communication time with the AP 13 by the AP communication unit 107 is longer than a predetermined time. Thus, even if the connection from the hall computer 22 to the key 11 via the public line 23 fails, the key 11 communicates with the hall computer 22 via the public line 23. By doing so, it becomes possible to increase the possibility that the position information of the key 11 when the key 11 is taken out of the store 1 is transmitted to the hall computer 22.

[Key management processing by hall computer in FIG. 31]
Next, the key management processing by the hall computer 22 in FIG. 31 will be described with reference to the flowchart in FIG. Note that the processing of steps S341 to S366 and S369 in the flowchart of FIG. 33 is the same as the processing of steps S101 to S127 in the flowchart of FIG. However, in step S364, if the count value of the wait timer does not exceed the specified time, the process proceeds to step S367.

  In step S367, the history management table 321 controls the public line communication unit 198 to determine whether there is a communication request from the key 11 via the public line 23. In step S367, for example, when communication via the public line 23 is requested by the process of step S321 of FIG. 32 described above, the process proceeds to step S368.

  In step S368, the history management table 321 executes an operation history storage process, acquires position information from the key 11 via the public line 23, and stores it in the table as an operation history.

[Operation History Saving Processing by Hall Computer in FIG. 31]
Here, with reference to the flowchart of FIG. 34, the operation history storing process by the hall computer 22 of FIG. 31 will be described. Note that the processes in steps S401 to S425 and S427 to S432 in the flowchart of FIG. 34 are the same as the processes in steps S171 to S201 in the flowchart of FIG.

  That is, none of the first AP command to the third AP command supplied from the AP 13 by the processing of steps S401, S416, and S422. Therefore, in step S426, the history management table 321 is keyed via the public line communication unit 198. 11 determines whether it is a request for communication connection via the public line 23. In step S426, the key 11 is in a state where communication with the AP 13 is disabled and the unconnected time has elapsed, or a communication connection is requested from the key 11 via the public line 23. As described above, in the case of step S368 subsequent to step S367 in the flowchart of FIG. 33, since the communication connection is requested from the key 11 via the public line 23, the process proceeds to step S433.

  In step S433, the history management table 321 controls the public line communication unit 198 to make a communication connection in response to a communication request with the key 11 via the public line 23.

  In step S434, the history management table 321 acquires and stores date / time information from the RTC 195, and the process proceeds to step S430.

  That is, in the subsequent process, the location information of the key 11 by the GPS 104 is requested and acquired through communication via the key 11 and the public line 23, and the information is registered in the history management table 321.

  If the unconnected time with the AP 13 exceeds the predetermined time by the above processing, the key 11 requests communication connection to the hall computer 22 through the public line 23 in addition to the hall computer 22, and the position information by the GPS 104 is stored in the hall. Since transmission to the computer 22 is possible, even if the communication connection from the hall computer 22 to the key 11 via the public line 23 does not go well for some reason, the hall computer 22 is in the position of the key 11. The possibility that information can be acquired can be increased. Further, here, in addition to enabling the location information to be acquired from the hall computer 22 to the key 11 by communication via the public line 23, it is further possible to communicate from the key 11 to the hall computer 22 via the public line 23. In this example, the position information of the key 11 can be acquired with a high probability. However, only the key 11 requests the hall computer 22 for communication connection via the public line 23 and transmits the position information. You may be able to do it. Further, the setting of the predetermined time with respect to the unconnected time between the key 11 and the hall computer 22 may be different. For example, for the hall computer 22 having a sufficient power supply, the predetermined time with respect to the unconnected time is shortened, 11, as soon as communication with the AP 13 becomes impossible, the location information is requested through the public line 23, and for the key 11 with only a battery with a limited power source, the predetermined time with respect to the unconnected time is lengthened. The communication to the hall computer 22 through the public line 23 may be performed only when the worst situation occurs.

  As described above, according to the present technology, it is always monitored where a plurality of pre-registered keys exist in a predetermined area, and the usage state of each key is managed in real time. By managing the state of gaming machines that can be operated (unlocked) with individual keys, it becomes possible to improve the security of the related gaming machines and keys. Also, by storing the key position information and operation history in association with the time, it is possible to manage the movement flow history and operation history of each key, and to grasp the behavior of the clerk with each key Become. In addition, it is a key used for locks with a conventional simple structure that does not require authentication processing for unlocking and locking, and is frequently changed by the user when using the same key multiple times. Even under such usage conditions, it is possible to manage the usage status for each key.

  By the way, the series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a recording medium in a general-purpose personal computer or the like.

  FIG. 35 shows a configuration example of a general-purpose personal computer. This personal computer incorporates a CPU (Central Processing Unit) 1001. An input / output interface 1005 is connected to the CPU 1001 via a bus 1004. A ROM (Read Only Memory) 1002 and a RAM (Random Access Memory) 1003 are connected to the bus 1004.

  The input / output interface 1005 includes an input unit 1006 including an input device such as a keyboard and a mouse for a player to input an operation command, an output unit 1007 for outputting a processing operation screen and an image of the processing result to a display device, a program and various data. Are connected to a storage unit 1008 including a hard disk drive and the like, and a local area network (LAN) adapter and the like, and a communication unit 1009 that executes communication processing via a network represented by the Internet. Also, a magnetic disk (including a flexible disk), an optical disk (including a CD-ROM (Compact Disc-Read Only Memory), a DVD (Digital Versatile Disc)), a magneto-optical disk (including an MD (Mini Disc)), or a semiconductor A drive 1010 for reading / writing data from / to a removable medium 1011 such as a memory is connected.

  The CPU 1001 is read from a program stored in the ROM 1002 or a removable medium 1011 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, installed in the storage unit 1008, and loaded from the storage unit 1008 to the RAM 1003. Various processes are executed according to the program. The RAM 1003 also appropriately stores data necessary for the CPU 1001 to execute various processes.

  In this specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in time series in the order described, but of course, it is not necessarily performed in time series. Or the process performed separately is included.

  Further, in this specification, the system represents the entire apparatus constituted by a plurality of apparatuses.

  The embodiments of the present technology are not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present technology.
