Description

  The present invention relates to a screen lock absence display system, and more particularly to a technique for notifying a user's whereabouts using a large number of electronic device systems installed in various places.

  Since activities as a member of society usually involve moving to various places, it is very important to inform family, colleagues, friends, etc. of their destination and whereabouts. In particular, in the case of a member of a company organization, business trips to various departments, such as the head office, branch offices, sales offices, and factories, are daily activities, and inform your boss, colleagues, and subordinates about your destination and whereabouts. There is a need. As such a contact method, a method of placing a memo describing a destination in his / her seat, a method of writing a destination on a bulletin board, and the like have been used as conventional means.

  On the other hand, today, communication means using a network have become widespread, and a method for transmitting a message about his / her location and destination by sending / receiving electronic information has been proposed. For example, Patent Document 1 below discloses a system that displays a destination of an input setter on an electronic bulletin board based on information input via an external communication line. Patent Document 2 below discloses a system that displays a bulletin board indicating a destination of each employee on a personal computer using a Web server. If this system is used, it is possible to immediately display the destination and location of other members on a terminal device such as a personal computer.

JP-A-11-305695 JP 2002-49728 A

  In the conventional system described above, it is assumed that information on a destination or whereabouts of a specific member is entered and set in advance by the member himself / herself or another member who has received the instruction. For example, a member who is planning to travel to the head office needs to input information indicating the destination and whereabouts as data into the system in advance, such as “Head office in the afternoon”. The system only has a function of collecting information based on such self-reports and presenting the information in the form of an electronic bulletin board or the like. In other words, unless each member actively self-reports, the correct destination cannot be posted.

  As described above, in the system based on active self-reporting, there is an adverse effect that the workload of “declaring the destination” is imposed on individual members in operation. There also arises a problem that the presentation cannot be made. For example, the work burden of self-reporting about “Head office in the afternoon” may not be so much, but “1: 00 to 1:40 is the conference room on the 7th floor of the head office building, 1:50 to 3:00 , The meeting room in the 7th section of the sales headquarters on the 3rd floor of the headquarters building, 4: 0 to 5:00 pm will be self-reported on a detailed business trip schedule, such as the 4th clean room on the 5th floor of the 4th building of the Saitama factory. If such an operation is performed, the work burden on individual members must be extremely large.

  On the other hand, from the standpoint of another member who uses destination information about a specific member, rough information such as “Headquarters in the afternoon” is not very useful. Even if it is desired to contact a specific member, it is difficult to immediately contact only with information such as “Headquarters in the afternoon”, and it is preferable to obtain destination information as detailed as possible.

  Therefore, an object of the present invention is to provide a system capable of reducing the burden of reporting work related to a destination and whereabouts by individual members and presenting the destination and whereabouts in detail.

  Hereinafter, the present invention will be described based on the illustrated embodiments.

<<< §1. Basic concept of the present invention >>
An object of the system according to the present invention is to notify another member of whereabouts of a specific member. However, in the present invention, as a method of achieving such an object, a method of using an existing hardware system is employed instead of constructing a new hardware system. That is, in the present invention, a plurality of electronic devices installed in different places, and a portable information recording medium having a function of communicating with the electronic device and performing authentication when using each electronic device, And a method of presenting a location of a user who uses the system by using an electronic device system configured by connecting each electronic device via a network.

  For example, FIG. 1 shows an example of such an electronic device system. In the case of the illustrated example, a state in which four electronic devices 101 to 104 are connected to the network N is shown. The four electronic devices 101 to 104 are installed in different places, and can communicate with each other via the network N. Here, it is assumed that these four electronic devices 101 to 104 are installed in different facilities as equipment of a specific company, and all of them are composed of personal computers, and the following explanation will be given. To do.

  Specifically, as illustrated, the electronic device 101 is a personal computer installed at the Tokyo head office, the electronic device 102 is a personal computer installed at the Yokohama branch, and the electronic device 103 is installed at the Chiba branch. It is assumed that the electronic device 104 is a personal computer installed in the Saitama factory. Of course, in practice, each location is usually equipped with a larger number of personal computers and other electronic devices instead of a single personal computer, but here, for convenience of explanation, one location is one. Consider a simple model with only one computer installed. The network N may be an in-house LAN or the Internet.

  On the other hand, each company employee is provided with an information recording medium as an employee ID card. Here, it is assumed that an information recording medium 201 is supplied to a specific employee A as shown in the figure. The information recording medium 201 is a portable medium having a function of performing authentication by communicating with the electronic device to be used when each of the electronic devices 101 to 104 is used. It is used. Of course, in implementing the present invention, the information recording medium 201 is not necessarily an IC card. For example, a device such as a mobile phone or a PDA may be used as the information recording medium 201. In short, any medium may be used as the information recording medium 201 as long as it is a portable medium having a function of communicating with an electronic device to be used and performing authentication. However, recently, an increasing number of companies issue IC cards as employee cards. Here, an example in which an employee card consisting of an IC card is used as it is as an information recording medium 201 will be described.

  Here, it is assumed that the employee A is a staff member of the Chiba branch office, has a desk in the building of the Chiba branch office, and the electronic device 103 is supplied as a desktop personal computer dedicated to the employee A. Therefore, the employee A usually performs business using the electronic device 103 at his / her seat in the Chiba branch office. However, this employee A is given the authority to use the electronic device 101 installed at the Tokyo head office, the electronic device 102 installed at the Yokohama branch, and the electronic device 104 installed at the Saitama factory as needed. When a business trip is made to a place, business can be performed using each electronic device installed in each place.

  Of course, when each electronic device is used, it is authenticated whether or not the user is authorized to use the electronic device. Such authentication is performed using the information recording medium 201 as described above. As shown in the figure, authentication information unique to the owner is recorded on the information recording medium 201. The information recording medium 201 has a function of communicating with each of the electronic devices 101 to 104. When the employee A uses a specific electronic device, the electronic device and the information recording medium to be used are used. 201 to communicate with the authentication process. Of course, the electronic device can be used only when correct authentication is performed.

  FIG. 1 shows a state in which an electronic device 103 (a desktop personal computer supplied to employee A) installed in the Chiba branch office and an information recording medium 201 are in communication. As described above, in the case of the example shown here, since the IC card provided as the employee ID is used as the information recording medium 201, the electronic device 103 (personal computer) actually has a reader / writer for the IC card. An apparatus is provided, and employee A inserts an employee ID card into the reader / writer apparatus so that the two can communicate with each other. When a contact type IC card is used as the information recording medium 201, communication between the two is performed through electrodes that are physically in contact with each other. However, when a non-contact type IC card is used, Communication between the two is performed by wireless communication.

  When the employee A starts using the electronic device 103 (personal computer), first, the information recording medium 201 (employee card) is inserted into a reader / writer device provided in the electronic device 103 to perform a predetermined login procedure. (Also called the logon procedure). In this login procedure, the electronic device 103 performs processing for authenticating that the information recording medium 201 is a legitimate medium. Various processes are known as such an authentication process.

  For example, the random number data generated on the electronic device 103 side is given to the information recording medium 201, and the random number data is encrypted using the unique authentication information recorded on the information recording medium 201 side to generate encrypted data Then, the encrypted data is returned to the electronic device 103 side, and processing for determining whether or not the encrypted data is correct may be performed. Specifically, for example, if the unique authentication information recorded on the information recording medium 201 side is also prepared on the electronic device 103 side (or the server device connected to the network N has this unique information). Authentication information may be prepared), and the encrypted data can be generated using the same authentication information on the electronic device 103 side, so that the encrypted data and the encrypted data returned from the information recording medium 201 match. You can check whether you want to do it.

  The above authentication processing is processing for the electronic device 103 side to authenticate the information recording medium 201 as a correct medium. Usually, however, the reverse authentication processing, that is, the information recording medium 201 side corrects the electronic device 103 correctly. The process for authenticating with the device is also executed, and the login procedure is completed only when the other party is authenticated as the correct device. In this login procedure, the employee A is usually required to input a password. Since the processing related to such a login procedure is a known technique, a detailed description thereof is omitted here.

  An important point in the present invention is that when the employee A uses the electronic device 103, an authentication procedure using the information recording medium 201 is required. The employee A is in his / her seat at the Chiba branch office. When business is performed, it is necessary to connect the information recording medium 201 to the electronic device 103 and perform authentication as illustrated. It should be noted that after the authentication is successful and the login procedure is completed, it is possible to take an operation form in which the information recording medium 201 can be extracted from the electronic device 103. Until this is done, there are many cases where the operation mode is such that the information recording medium 201 remains connected to the electronic device 103.

  Now, when this employee A makes a business trip to the Tokyo head office, it is possible to use the electronic device 101. In this case as well, the information recording medium 201 is also connected to the electronic device 101 to perform authentication. You need to log in. As described above, the employee A can use any of the electronic devices 101 to 104 as necessary, but at the time of use, an authentication process using the information recording medium 201 is required.

  The general configuration of the electronic device system shown in FIG. 1 has been described above, but the electronic device system itself having such a configuration is already a well-known system and is actually used by many companies. Of course, such an electronic device system itself is not a system constructed for the purpose of notifying the whereabouts of employees, but for performing various business processes while exchanging information with each other using the network N. It is a built system. The basic point of the present invention is that “an additional process of notifying the location of an employee is executed using such an electronic device system”.

  As described above, the employee A can use each of the electronic devices 101 to 104 as necessary, but at the time of use, an authentication process using the information recording medium 201 is always required. In other words, when the authentication process using the information recording medium 201 (employee A's employee ID card) is executed in a specific electronic device, the employee A intends to use the specific electronic device. The current location of employee A is the installation location of the specific electronic device. By utilizing such characteristics, this system can grasp the whereabouts of the employee A even if the employee A does not actively perform the reporting work regarding his destination and whereabouts. Can be notified to any electronic device.

  The present invention is based on such a basic concept, and in order to notify such whereabouts, each of the electronic devices 101 to 104 has a device identification code assigned to identify itself, Stores location information indicating its own location.

  For example, in FIG. 1, the small block “self: C101” shown in the block of the electronic device 101 stores a device identification code “C101” for identifying itself in the electronic device 101. (The character “self:” shown in the figure is for clarifying on the drawing that this code “C101” is a code indicating itself. Is not required). In addition, in the small block “location: Tokyo head office” shown in the block of the electronic device 101, location information “Tokyo head office” indicating its own installation location is stored in the electronic device 101. (The letters “Location:” shown in the figure are intended to clarify on the drawing that this code “Tokyo headquarters” is the information indicating the installation location of itself. Is not required). The same applies to the small blocks shown in the blocks of the other electronic devices 102 to 104.

  In the present invention, the following three steps are executed in order to present the location of the user (employee A in this example) on a specific electronic device. First, in the first step, a process of recording information indicating “a specific electronic device for presenting a location” on the information recording medium 201 is performed. Here, this “specific electronic device that presents the location” is referred to as “report target”.

  In the information recording medium 201 shown in FIG. 1, three types of information “authentication information”, “self: C201”, and “report target: C103” are recorded. Of course, since the information recording medium 201 is an IC card that functions as an employee ID card for employee A, various other information is recorded, so the above three types of information are related to the present invention. It will be information to do.

  Here, as described above, “authentication information” is information used for authentication processing with the electronic device to be used, and usually authentication information consisting of a unique code for each individual employee ID card is used. To be recorded. On the other hand, “C201” is a medium identification code for specifying the information recording medium 201 itself, and a unique code is given to each information recording medium (the character “self:” shown in the figure is This code “C201” is for clarifying that it is a code indicating itself and is not actually required). “Report target: C103” is the code recorded in the first step described above, and “specific electronic device (report target) for presenting whereabouts” for employee A is the device identification code “C103”. The electronic device 103 specified by

  The user (employee A in this example) can freely determine which electronic device the “report target” is set to. As will be described later, the electronic device that has been “reported” will be notified of its whereabouts, so the electronic device installed at the location where you want to be notified of is set as “reportable” do it. The example shown in the figure shows a case where employee A sets the personal computer (electronic device 103) of his / her seat installed in the Chiba branch as “report target”. The “report target” can be set by writing a predetermined device identification code on an information recording medium using any electronic device. Note that the characters “Report Target:” shown in the figure are for clarifying on the drawing that the code “C103” is a device identification code indicating the electronic device to be “Report Target”. Actually it is unnecessary.

  The subsequent second step is executed when the user (employee A in this example) performs authentication for using a specific electronic device. That is, this second step is a process executed by each electronic device. When the electronic device to be used communicates with the information recording medium 201, “2” is recorded in the information recording medium 201. This is a process of transmitting location information indicating its own location via the network N to a “specific electronic device (report target) that presents a location”.

  For example, let us consider a case where employee A makes a business trip to the Tokyo head office and uses the electronic device 101. In this case, as described above, the employee A needs to log in to the electronic device 101 using the information recording medium 201 carried as the employee ID card. Communication is performed with 101, and an authentication process using the authentication information is executed. At this time, the electronic device 101 reads the device identification code “C103” indicating “report target” recorded in the information recording medium 201, and recognizes that the “report target” is the electronic device 103. Then, the location information indicating its own location is transmitted to the electronic device 103 that is the “report target” via the network N. In the illustrated example, a code including a character string “Tokyo head office” stored in advance in the electronic apparatus 101 is transmitted as the location information.

  Note that such processing in the second step may be executed before authentication between the electronic device 101 and the information recording medium 201, but in practice, false location information is transmitted. In order to prevent this, it is preferable to execute the process of the second step only when the authentication between the two is correctly performed.

  The final third step is a process performed on the electronic device side that is the “report target”, and the electronic device that has received the location information via the network N presents the location information. In the case of the above example, the electronic device 101 installed at the Tokyo head office transmits a code consisting of the character string “Tokyo head office” to the electronic device 103 (report target) installed at the Chiba branch office. The electronic device 103 performs a process of displaying this on the display screen. Of course, in practice, it is preferable to display the message in an appropriate message format such as “I am now at the Tokyo head office”.

  By presenting the whereabouts in this way, a colleague who is enrolled in the Chiba branch office looks at the display screen of the electronic device 103 (PC) installed in the seat of the employee A, so that the whereabouts of the employee A is displayed. Can be recognized. Moreover, in order to present such a whereabouts, the employee A does not need to actively perform a work of declaring the whereabouts. Of course, it is necessary to set an electronic device that is a “report target” in advance for the information recording medium 201 (first step). Without performing work, the user's whereabouts can be presented on an electronic device to be “reported”.

  In addition, the system according to the present invention can present a user's whereabouts by using an existing electronic device system connected to a network as it is, so that there is an advantage that the introduction cost can be kept very low. Currently, many companies' business operations are executed by network-connected computer systems. For security reasons, when logging into individual terminal devices (electronic devices) in such systems, employee IDs are used. Authentication using an information recording medium such as the above is performed. According to the present invention, a function as a whereabouts presentation system can be realized only by adding some software to such an existing system. Specifically, the system according to the present invention is realized simply by incorporating a dedicated program for executing the first to third steps described above into each electronic device or an information recording medium as necessary. It becomes possible.

  After all, the system shown in FIG. 1 has a plurality of electronic devices 101 to 104 installed in different places, and a function of performing authentication by communicating with the electronic devices when using each of these electronic devices. It can be said that it is a system that can be constructed using an existing system having the feature that each of the electronic devices 101 to 104 is connected to each other via a network. .

  That is, in such an existing system, information indicating a specific electronic device to be “reported” (device identification code “C103” in the illustrated example) is recorded in advance on the information recording medium 201. Each of the electronic devices 101 to 104 has a specific electronic device (in the illustrated example, the electronic device 103) to be reported that is recorded in the information recording medium 201 when communicating with the information recording medium 201. Thus, it is only necessary to provide a function of transmitting location information indicating its own location via the network N. If it does so, since the location information which shows a user's whereabouts will be automatically notified to the electronic device side used as a report object, it becomes possible to present this as needed.

  In FIG. 1, only the information recording medium 201 issued as the employee ID of the employee A is shown for convenience of explanation, and only the case of notifying the whereabouts of the employee A has been described. The information recording medium as the employee ID card is issued for each employee. For example, the information recording medium 202 is issued to another employee B, and the information recording medium 203 is issued to another employee C. In the process of the first step described above, each employee may set a desired electronic device as a “report target” for the information recording medium for each employee. Then, the whereabouts of employee B is presented in the “report target” set in the information recording medium for employee B, and the whereabouts of employee C is set in the “reporting” set in the information recording medium for employee C. It will be presented to the “subject”.

  In some cases, a plurality of employees may set the same electronic device as a “report target”. For example, when the electronic device 103 installed in the illustrated Chiba branch office is a personal computer shared by the employees A, B, and C, all of the employees A, B, and C have the electronic device 103 as a “report target”. It can also be set. In this case, for example, even if the location information “Tokyo headquarters” is transmitted from the electronic device 101 to the electronic device 103, it is distinguished which information indicates the location of the employees A, B, and C. I can't.

  Therefore, in practice, a predetermined medium identification code for identifying itself is recorded in each information recording medium so as to cope with the above-described case. For example, in the example of FIG. 1, a medium identification code “C201” for indicating self is recorded in the information recording medium 201. Then, when each electronic device communicates with a specific information recording medium, the information together with the location information indicating its own location with respect to the specific electronic device to be reported recorded on the information recording medium What is necessary is just to perform the process which transmits the medium identification code currently recorded on the recording medium via a network.

  For example, in the example shown in FIG. 1, it is assumed that employee A has performed a login procedure for the electronic device 101 at the Tokyo head office. In this case, first, the electronic device 101 performs an authentication process using the “authentication information” in the information recording medium 201, and sets the medium identification code “C 201” recorded in the information recording medium 201 and the report target. A process of reading the device identification code “C103” shown is executed. Subsequently, the electronic device 101 performs processing of transmitting the location information “Tokyo head office” indicating its own installation location and the read medium identification code “C201” to the electronic device 103 that is the report target.

  If such processing is executed, when the employee A performs a login procedure for the electronic device 101 at the Tokyo head office, not only the location information “Tokyo head office” is stored in the electronic device 103 of the Chiba branch office, Since the medium identification code “C201” is transmitted, it is possible to present the information that the location of the employee holding the employee ID specified by the medium identification code “C201” is “Tokyo head office”. Of course, if the list indicating the correspondence relationship between the medium identification code and the employee name is referred to, the electronic device 103 is that the employee holding the employee ID specified by the medium identification code “C201” is the employee A. Therefore, it is possible to present a message such as “Employee A is now at the Tokyo head office”. Of course, the whereabouts of employee B and employee C can be presented in the same manner.

  Alternatively, if a character code indicating a name such as “employee A” is used instead of a code such as “C201” as a medium identification code recorded in the information recording medium 201, the electronic device 103 may be Will send a medium identification code of “Employee A” along with the location information of “Tokyo Headquarters”, so without referring to the list, “Employee A is now in Tokyo Headquarters” A message can be presented.

  As described above, when a medium identification code such as “C201” or “employee A” is recorded in the information recording medium 201, a plurality of employees set the same electronic device as “report target”. It will be possible to handle cases. However, in other words, if there is no case where a plurality of employees set the same electronic device as a “report target”, it is not always necessary to record a medium identification code in the information recording medium 201. Absent.

  For example, if the electronic device 103 is a personal computer dedicated to employee A and other employees cannot set this personal computer as “report target”, record the medium identification code “C201” shown in the figure. There is no problem even if omitted. In this case, the location information transmitted with the electronic device 103 as the “report target” is always information indicating the whereabouts of the employee A. Therefore, the message displayed on the electronic device 103 is “currently in Tokyo head office”. Even if it is only the information indicating the place such as “We are”, it is clear that the message is a message indicating the location of the employee A.

  Therefore, in carrying out the present invention, it is not essential to record the medium identification code on the information recording medium side or to transmit the medium identification code to the “report target”.

For example, in the example shown here, the information recording medium 201 is an IC card issued as an employee card to the employee A, and therefore has hardware such as a CPU and a memory. Various programs and data necessary for the functions are stored. The components 21 to 24 are obtained by capturing a specific function of the information recording medium 201 as one component, and are actually realized by incorporating dedicated software into the hardware constituting the IC card. Is.

  The communication unit 21 that is a constituent element of the information recording medium 201 is a constituent element that performs a function for communicating with an electronic device. As described in §1, the communication between the two may be a contact type communication in which the electrodes are physically brought into contact with each other, or may be a non-contact type communication using radio, but the communication unit 21 performs the communication processing. It is constituted by hardware and software in the IC card involved. On the other hand, the authentication information storage unit 22, the report target device registration unit 23, and the medium identification code storage unit 24 are configured by one area of the memory in the IC card.

  The authentication information storage unit 22 is a component that stores authentication information necessary for causing the electronic device to perform correct authentication. As described in §1, the electronic device is stored in the authentication information storage unit 22. Authentication information is used to authenticate that the information recording medium 201 is a correct medium.

  The report target device registration unit 23 is a component that stores information indicating the report target device. Specifically, a device identification code indicating a specific electronic device set as “report target” is stored. In the figure, as an example, an example in which a device identification code “C103” (an identification code of the electronic device 103) is stored is shown. This is because the electronic device 103 is registered as “report target”. It means that

  The medium identification code storage unit 24 is a component that stores a medium identification code for identifying the information recording medium 201 itself. The figure shows an example in which a medium identification code “C201” (identification code of the information recording medium 201) is stored as an example. The information recording medium is provided to each employee as an employee ID card, and predetermined medium identification codes different from each other are recorded in the medium identification code storage unit 24 of each information recording medium. . If there is no confusion among employees with the same surname, as described above, a name such as “employee A” may be used as a medium identification code.

  On the other hand, the communication unit 17 that is a component on the electronic device 103 side is a component that performs a function for communicating with an information recording medium. In practice, a personal computer and its peripheral devices (this device) involved in the communication process In the case of the example, it is constituted by hardware and software of a reader / writer device.

  The authentication unit 16 authenticates the information recording medium using authentication information stored in the information recording medium in communication, and permits use of the electronic device when a correct authentication result is obtained. Fulfill. In the illustrated example, in order for the employee A to log in to the electronic device 103, the information recording medium 201 as the employee ID is inserted into the reader / writer device on the electronic device 103 side, and the communication between the two is performed. Show. In such a state, the authentication unit 16 uses the authentication information stored in the authentication information storage unit 22 to authenticate whether the information recording medium 201 is a legitimate medium in this system. It will be.

  In the figure, a broken-line arrow is drawn between the authentication unit 16 and the network N, but this is shown by the authentication unit 16 via the network N if necessary for the authentication process. It indicates that no server device can be accessed. Of course, if the authentication unit 16 has a function of performing authentication alone, access via the network N is unnecessary.

  The device identification code storage unit 11 is a component that stores a device identification code assigned to itself so that each electronic device can be mutually identified on the network N, and the location information storage unit 12 is installed by itself. This is a component that stores location information indicating the location that has been set. Each of these is actually constituted by a storage area such as a hard disk device of a personal computer constituting the electronic device 103. In the figure, as an example, an example in which a device identification code “C103” (identification code of the electronic device 103) and location information “Chiba branch office” (installation location of the electronic device 103) is stored is shown. Yes.

  The location information transmission unit 14 reads the device identification code written in the report target device registration unit of the information recording medium in communication, and stores the location information for another electronic device specified by the read device identification code. It fulfills the function of transmitting its own location information stored in the unit 12 via the network N. This function is a function for performing processing corresponding to the second step described in §1.

  However, in the case of the example shown in FIG. 2, since the electronic device 103 itself is “report target”, the location information transmission unit 14 does not actually transmit the location information. That is, when the device identification code “C103” read from the report target device registration unit 23 matches the device identification code “C103” stored in the device identification code storage unit 11, the location information transmission unit 14 Recognize that you are the “report target” and do not send location information.

  The location information transmission unit 14 performs processing substantially corresponding to the second step, for example, when the employee A travels to the Tokyo head office and logs in to the electronic device 101. In this case, since the electronic device shown in the upper part of FIG. 2 is the electronic device 101 installed in the Tokyo head office, the device identification code “C103” read from the report target device registration unit 23 is the device identification code storage unit. 11 does not match the device identification code “C101” stored in the device 11. Therefore, the location information transmission unit 14 transmits its own location information “Tokyo head office” stored in the location information storage unit 12 to another electronic device 103 that is “report target” via the network N. To send.

  At this time, the location information transmission unit 14 in the electronic device 101 reads the medium identification code “C201” together with the device identification code “C103” indicating “report target” from the information recording medium 201 in communication, and “report target”. The electronic device 103 is transmitted with its own location information “Tokyo head office” stored in the location information storage unit 12 and the read medium identification code “C201” via the network N. As a result, information indicating that the location of “employee A” corresponding to the medium identification code “C201” is “Tokyo head office” is transmitted to the electronic device 103. If such an operation is performed, as described above, a case where a plurality of employees such as employees A, B, and C set the same electronic device as a “report target” can be dealt with.

  However, as described in §1, when there is no case where a plurality of employees set the same electronic device as a “report target”, it is necessary to provide a medium identification code storage unit in the information recording medium 201. There is no. In this case, the location information transmission part 14 should just have the function to transmit only location information.

  On the other hand, the location information presentation unit 13 is a component that stores the location information transmitted to itself through the network N and performs a function of presenting the location information in a predetermined method. When the location information transmitting unit 14 has a function of transmitting a medium identification code together with location information, the medium identification code or a user name corresponding thereto may be presented together with the location information. This function is a function for performing processing corresponding to the third step described in §1.

  For example, if only the location information “Tokyo headquarters” is sent (as described above, there is no case where multiple employees set the same electronic device as “reportable”), the electronic device Since it is used as a dedicated machine to present the location of a specific employee, it is only necessary to present such as “I am at the Tokyo head office now”. On the other hand, when the medium identification code “C201” is transmitted together with the location information “Tokyo headquarters”, a presentation such as “C201 is in Tokyo headquarters” may be made, or refer to the correspondence list. By recognizing that the medium identification code “C201” corresponds to “employee A”, a presentation such as “employee A is at the Tokyo head office” may be made. Of course, if a character string indicating a name such as “employee A” is used as the medium identification code, a presentation such as “employee A is at the Tokyo headquarters” will be displayed without referring to the correspondence list. It becomes possible.

  The report target writing unit 15 to be described last is a component that performs the function of writing its own device identification code stored in the device identification code storage unit 11 into the report target device registration unit in the information recording medium in communication It is. This function is a function for performing processing corresponding to the first step described in §1. For example, if the employee A gives a write instruction to the report target writing unit 15 while logging in to the electronic device 103 that is his / her personal computer using the information recording medium 201 that is his / her employee ID card, The device identification code “C103” stored in the device identification code storage unit 11 is written in the report target device registration unit 23 on the information recording medium 201 side. FIG. 2 shows a state in which such a writing process is completed.

  Of course, the employee A can change the registration contents of the report target device registration unit 23 at any time. For example, in the case where a short-term transfer instruction is given, which is to be transferred to the Yokohama branch for only one month, the employee A uses the information recording medium 201 that is an employee ID and the electronic device installed at the Yokohama branch. In a state where the device 102 is logged in, a writing instruction may be given to the report target writing unit 15 in the electronic device 102. Then, the device identification code “C102” stored in the device identification code storage unit 11 in the electronic device 102 is written in the report target device registration unit 23 on the information recording medium 201 side. At this time, if overwriting is performed, the device identification code “C103” in the report target device registration unit 23 is rewritten to a new code “C102”, and thereafter, the Yokohama branch office is informed. The installed electronic device 102 is the “report target” for employee A. Of course, when employee A returns to the Chiba branch after one month, he / she can log in to the electronic device 103 again and give a writing instruction to the reporting target writing unit 15 to report the device to be registered. 23, the device identification code “C102” is returned to the original “C103”.

  Further, if the reporting target writing unit 15 is provided with an additional writing function, a plurality of electronic devices can be registered as “reporting targets”. For example, consider a case where employee A who has returned to the Chiba branch office is engaged in operations such as going back and forth between the Saitama factory and the Chiba branch office every day. In this case, the employee A logs in to the electronic device 104 installed in the Saitama factory using the information recording medium 201 that is an employee ID, and reports to the report target writing unit 15 in the electronic device 104. What is necessary is just to give the write instruction by additional writing.

  Then, the device identification code “C104” stored in the device identification code storage unit 11 in the electronic device 104 is additionally written in the report target device registration unit 23 on the information recording medium 201 side. Both the electronic device 103 and the electronic device 104 are registered as “report targets”. Therefore, since the location of employee A will be presented to both the electronic device 103 and the electronic device 104 after that, when you are in the Chiba branch office, the electronic device 104 in the Saitama factory will say "I am in Chiba branch office." Is presented, and “I am in Saitama factory” is presented to the electronic device 103 of the Chiba branch office when I am in the Saitama factory. Of course, when employee A makes a business trip to the Tokyo head office, both the electronic devices 103 and 104 are presented with “I am in Tokyo head office”.

  In short, if the device identification code related to a plurality of electronic devices can be written in the report target device registration unit 23 in the information recording medium, the location information transmitting unit 13 reports the information on the information recording medium in communication. When a plurality of device identification codes are written in the device registration unit 23, information may be transmitted to each electronic device specified by each device identification code.

  In addition, the reporting target writing unit 15 writes not only its own device identification code (that is, the device identification code stored in the device identification code storage unit 11) but also any device identification code designated by the user. It is also possible to have a function. In this case, for example, the employee A in the Chiba branch office can perform a process of adding an arbitrary electronic apparatus as a “report target” simply by operating the electronic apparatus 103 installed in the Chiba branch office.

  In addition, when the report target writing unit 15 is provided with such an additional writing function, it is preferable to have a deletion function. Specifically, a list of device identification codes currently registered in the report target device registration unit 23 is displayed for the information recording medium currently in communication, and a specific device designated by the user from among them is displayed. A process for deleting the identification code may be performed. As described above, if the “report target” can be added or deleted at any time, the user can freely set the “report target” as necessary.

<<< §3. Essential components of electronic equipment >>>
As described above, in §2, the basic configuration of the electronic device and the information recording medium used in the present invention has been described with reference to FIG. The medium identification code storage unit 24 in the information recording medium is not indispensable, and in the case where there is no case where a plurality of employees set the same electronic device as “report target”, the information recording medium 201 In addition, it is not always necessary to provide the medium identification code storage unit 24. In this case, the location information transmission unit 14 has only to have a function of transmitting only location information.

  On the other hand, referring to the electronic device, not all the components included in the electronic device 103 of FIG. 2 are necessarily required for all the electronic devices used in the system of the present invention. Therefore, in this §3, supplementary explanation regarding essential components of the electronic device used in the present invention will be given.

  In the present invention, a plurality of electronic devices connected to each other via a network are essential. However, considering the operating principle of the present invention, it can be understood that the electronic device referred to in the present invention has two roles. That is, a role as a sender of location information and a role as a receiver of location information. For example, in the description so far with reference to FIG. 1, when employee A who has registered the electronic device 103 installed in the Chiba branch as “reporting target” travels to the Tokyo head office and logs in to the electronic device 101. The location information “Tokyo headquarters” is transmitted from the electronic device 101 to the electronic device 103 via the network N, and the message “I am now in Tokyo headquarters” is displayed on the display screen of the electronic device 103 of the Chiba branch office. An example is shown. In this case, the electronic device 101 serves as a sender of location information, and the electronic device 103 serves as a receiver of location information.

  As a result, the electronic device 103 shown in the upper part of FIG. 2 has a configuration capable of fulfilling both a role as a location information sender and a role as a location information receiver. Therefore, if all of the electronic devices 101 to 104 shown in FIG. 1 have the same configuration as the electronic device 103 shown in the upper part of FIG. 2, each of the electronic devices 101 to 104 serves as a sender of location information. And a role as a receiver of location information.

  However, in implementing the present invention, both roles are not necessarily required for all electronic devices connected to the network N. The present invention can be implemented even if a specific electronic device serves only as a sender of information and another specific electronic device serves only as a receiver of information. It is. Therefore, it is examined which component each component of the electronic device 103 shown in the upper part of FIG. 2 contributes to.

  First, the device identification code storage unit 11 is a component that stores a device identification code assigned to itself so that each electronic device can be mutually identified on the network N, and is used by connecting to the network N. This is an essential component for electronic equipment. That is, the device identification code storage unit 11 is a necessary component for both the information sender and receiver.

  On the other hand, the location information storage unit 12 and the location information transmission unit 14 are components necessary for transmitting the location information, and thus are components necessary only for the information sender. On the other hand, the location information presentation unit 13 is a component necessary for presenting the received location information, and thus is a component necessary only for the information receiver.

  What about the authentication unit 16 and the communication unit 17? First, these components are not necessary as information receivers. Since the function as an information receiver only needs to receive and present the location information transmitted to itself, it is not necessary to communicate with or authenticate the information recording medium. On the other hand, in order to fulfill the function as an information sender, the authentication unit 16 and the communication unit 17 are necessary. For example, in order to send the information that “Employee A is at the Tokyo head office”, the communication unit 17 communicates with the information recording medium 201 possessed by the employee A as an employee card, and the medium is a regular medium. It is necessary to authenticate that. Accordingly, the authentication unit 16 and the communication unit 17 are necessary components only for the information sender.

  In the end, in implementing the present invention, an electronic device that functions as an information sender is a device identification code storage unit 11 (in this example, “C110”) as shown in the electronic device 110 shown in FIG. An example in which a device identification code is stored is shown), a location information storage unit 12 (in this example, an example in which location information “Temporary branch office” is stored), a location information transmission unit 14, the authentication unit 16 and the communication unit 17 are sufficient. Similarly, in implementing the present invention, an electronic device for functioning as an information receiver is a device identification code storage unit 11 (in this example, “C120”) as shown in the electronic device 120 shown in FIG. An example in which the device identification code is stored is shown) and the location information presentation unit 13 is sufficient.

  The electronic device 110 shown in FIG. 3 is usually a personal computer installed at an unmanned temporary branch office. When an employee is traveling to this temporary branch office, another electronic device registered as “report target” for the employee is shown. It is necessary to send the location information “Temporary branch office” to the device. However, there is no need to display someone's whereabouts on this computer screen. In such a case, the electronic device 110 needs to serve as a sender of location information, but does not need to serve as a receiver of location information. Therefore, as shown in the figure, the electronic device 110 is composed of only essential components as a sender of location information.

  On the other hand, the electronic device 120 shown in FIG. 4 is an electronic bulletin board, and has only a function of displaying the location of a specific user (employee). Since the electronic device 120 does not have any other functions, the user does not perform any work for logging in using the employee ID card. Therefore, as shown in the figure, this electronic device 120 is composed of only essential components as receivers of location information.

  Note that an electronic device that does not have a function of receiving location information, such as the electronic device 110 shown in FIG. 3, is an “undesignated electronic device” that cannot be designated as a “report target”. On the other hand, the electronic device 103 shown in the upper part of FIG. 2 and the electronic device 120 shown in FIG. 4 are “designable electronic devices” that can be designated as “report target”.

  From the above viewpoint, in carrying out the present invention, there is at least one electronic device having a function as a sender of location information on the network N, and another electronic device having a function as a receiver of location information. There must be at least one device. Of course, in practice, it seems to be a common case to use a large number of electronic devices that can play the role of sender and receiver of location information, such as the electronic device 103 shown in the upper part of FIG. It is. However, it is not necessary for all electronic devices to be configured to play the roles of both the sender and the receiver. At least some of the electronic devices can play the role of the sender. It is sufficient to have a configuration that can play the role of the receiver.

  Finally, the necessity of the report target writing unit 15 will be described. The report target writing unit 15 is not an essential component for both the information sender and receiver. The report target writing unit 15 performs a process of writing a device identification code for a specific electronic device to be “report target” in the report target device registration unit 23 in the information recording medium in communication. Any device may be used. In other words, registration in the report target device registration unit 23 is not necessarily performed from any electronic device connected to the network N, and is an apparatus capable of performing writing processing on an information recording medium. Any device may be used as long as it is.

  However, in practice, it is preferable to provide the report target writing unit 15 in at least some electronic devices. In particular, the reporting target writing unit 15 incorporated in the electronic device 103 shown in the upper part of FIG. 2 records its own device identification code “C103” stored in the device identification code storage unit 11 during communication. Since the user has a function of writing in the report target device registration unit 23 in the medium, the user can designate an electronic device to be registered as a “report target” or perform an operation of inputting some device identification code. It is possible to execute processing for registering the electronic device currently logged in as “report target”.

  More preferably, when the report target writing unit 15 has requested the user to designate itself as a report target device, the device identification code stored in the device identification code storage unit 11 is When a process of writing in the report target device registration unit 23 in the information recording medium in communication is executed and a user request to designate an electronic device other than the self as a report target device is received, the device of the designated electronic device It is preferable to provide a function of executing processing for writing the identification code to the report target device registration unit 23 in the information recording medium in communication.

  Specifically, for example, when the report target writing unit 15 is activated, a message such as “Which electronic device is registered as a report target? (1) This device (2) Another device” is displayed. When the user selects (1), it is determined that there has been a user request to designate itself as a report target device, and the self stored in the device identification code storage unit 11 The process of writing the device identification code is executed. On the other hand, when the user selects (2), a list of electronic devices is again presented, and when the user selects a specific electronic device from the list, processing for writing the device identification code of the selected electronic device is performed. Just do it.

<<< §4. Variations of electronic equipment >>
The embodiments described so far have been related to an example in which the electronic device connected to the network N is a personal computer, but the electronic device referred to in the present invention is not necessarily a personal computer or a device equivalent thereto. There is no. In carrying out the present invention, in addition to a computer, a printer, a copying machine, and other office furniture and equipment (for example, a so-called multi-function machine having a plurality of functions such as a printer, a facsimile machine, a copying machine, an electronic locker, Office equipment such as cabinets), electronic locks, electronic bulletin boards, and the like can be used as electronic equipment. Hereinafter, embodiments using various electronic devices will be described.

  FIG. 5 is a block diagram showing a system according to another embodiment of the present invention. In this embodiment, various electronic devices are connected to the network N. The illustrated computers 101 to 104 are electronic devices equivalent to the electronic devices 101 to 104 shown in FIG. 1, and all have the same configuration as the electronic device 103 shown in the upper part of FIG. In other words, the computers 101 to 104 enclosed as the group G1 are electronic devices that serve as both senders and receivers of location information, and are electronic devices that can be designated as report targets.

  On the other hand, the electronic locks 111 and 113 and the printers 112 and 114 enclosed as the group G2 can serve as a sender of location information, but cannot function as a receiver of location information. . That is, the electronic device belonging to the group G2 is an electronic device equivalent to the electronic device 110 illustrated in FIG. 3 and cannot be designated as a report target.

  More specifically, the electronic lock 111 is an electronic lock attached to the entrance gate of the building X, and a specific employee uses an information recording medium (IC card) distributed as an employee card as an electronic key. As a result, the unlocking operation of the electronic lock 111 can be performed. Since all the examples described so far are examples of electronic devices consisting of personal computers, authentication processing using information recording media distributed as employee ID cards is positioned as processing required for login procedures to personal computers. there were. On the other hand, the authentication process performed in the electronic lock 111 is a process for determining whether or not the correct key code is stored in the information recording medium.

  For example, if the employee A is an employee who is permitted to enter and leave the building X, the information recording medium 201 that functions as the employee ID of the employee A is an electronic key for the electronic device that is the electronic lock 111. It will serve as a function. The authentication information stored in the electronic key has the meaning of the key code as the electronic key. When the electronic lock 111 confirms that this is the correct key code, the unlocking operation is permitted. Will be. The employee A inserts the information recording medium 201 functioning as an employee ID into the electronic lock 111 (if the information recording medium 201 is a non-contact type IC card, the employee A moves to the vicinity of the electronic lock 111) and releases the electronic lock 111. Pressing the lock button opens the entrance gate of Building X. Similarly, the electronic lock 113 is an electronic lock attached to the entrance gate of the building Y.

  While the electronic devices 101 to 104 are computers, the electronic devices 111 and 113 are electronic locks, and their original functions as electronic devices are completely different. However, from the viewpoint of an electronic device that is a component of the present invention, both are common in that they are electronic devices that play a role of a sender of location information. For example, if the employee A unlocks the electronic lock 111 using the information recording medium 201 that functions as an employee ID, the electronic lock 111 is registered with the location information “building X” as “report target”. It can be transmitted to the computer 103. As a result, on the display screen of the computer 103, a display such as “I am in the building X now” can be performed. Similarly, if the electronic lock 113 provided at the entrance gate of the building Y is unlocked, it is possible to display “I am in the building Y now”. In addition, if a similar electronic lock is provided at the exit gate of building X, when employee A passes through this exit gate, it is possible to display "I just left building X". is there.

  On the other hand, the printers 112 and 114 are so-called network connection type printers, but are printers that require authentication using an information recording medium that functions as an employee ID card in order to use them. For example, consider a case where employee A who enters building X enters a specific room (for example, room 112) in which printer 112 is installed and performs a printing operation. In this case, in order to use the printer 112, it is necessary to perform an operation equivalent to a login operation for a personal computer. That is, the employee A inserts the information recording medium 201 into the reader / writer device for the printer 112 (if the information recording medium 201 is a non-contact type IC card, the employee A moves near the printer 112), and follows a predetermined procedure. Authentication processing will be performed.

  When the employee A completes the authentication process for the printer 112 in this manner, the printer 112 functioning as an electronic device that plays the role of the location information is registered with the location information “building X, room 112” as “report target”. Can be transmitted to the computer 103. As a result, it is possible to display on the display screen of the computer 103 such as “I am now in Room X of Building X”. Similarly, when using the printer 114 installed in the 114th room of the building Y, a display such as “I am in the 114th room of the building Y” can be performed.

  As described above, examples of the electronic lock and the printer have been shown as the electronic devices belonging to the group G2, but various other devices can be used as the electronic devices referred to in the present invention. FIG. 5 further illustrates two electronic devices. That is, the electronic bulletin board 121 and the telephone 131.

  The electronic bulletin board 121 is a device equivalent to that described as the electronic device 120 in FIG. 4 and can only serve as a receiver of location information. For this purpose, the electronic bulletin board 121 is given a predetermined device identification code (a code “C121” in the illustrated example). The electronic bulletin board 121 has a function of receiving location information transmitted to itself via the network N and presenting it, and is one of electronic devices that can be designated as a report target.

  In order to register the electronic bulletin board 121 as a “report target”, as shown in the figure, the electronic bulletin board 121 itself may be written in the report target device registration unit 23 in the information recording medium. . Of course, in the case where a plurality of employees set the electronic bulletin board 121 as a common “report target”, the sender of the information together with the location information has a medium identification code (a code that can identify the employee who owns the medium). ) Can be displayed on the electronic bulletin board 121 as a list of “who is where”.

  On the other hand, the telephone 131 is an electronic device having a unique function slightly different from that of a normal telephone. That is, a predetermined device identification code (a code “C131” in the illustrated example) is assigned to the telephone 131. In addition, the telephone 131 can receive location information transmitted to itself via the network N, and an incoming call (incoming call via the telephone line T) to itself is specified by the received location information. It has a function to transfer to another telephone set in a place.

  Of course, the telephone 131 is one of electronic devices that can be designated as a report target. To register the telephone 131 as a “report target”, as shown in FIG. What is necessary is just to perform the process written in the report object apparatus registration part 23 in a recording medium.

  For example, it is assumed that the telephone 131 is a telephone installed at the seat of the employee A of the Chiba branch office, and the employee A normally uses the telephone 131. However, suppose that one day, employee A decides to travel to the Tokyo head office. In this case, if the employee A registers the telephone 131 as a “report target” in advance, the telephone addressed to the telephone 131 that has come to the telephone 131 during his / her absence in the following procedure: It can be picked up on the phone at the Tokyo head office.

  First, the employee A who made a business trip to the Tokyo head office performs authentication (login procedure) using the information recording medium 201 for the electronic device 101 installed in the Tokyo head office (a personal computer used for work at the Tokyo head office). ). As a result, the electronic device 101 transmits predetermined location information to the electronic device (telephone) 131 that is the “report target”. Here, it is assumed that more detailed location information such as “Meeting Room in Section 7 of the Sales Headquarters on the 3rd floor of the head office building” is set as the location information indicating the installation location of the electronic device 101. As a result, the detailed location information is transmitted to the telephone 131 via the network N.

  Here, a predetermined telephone number list is prepared as digital data in the telephone 131, and the location information “Meeting Room of Sales Division Section 7 on the 3rd floor of the head office building” is installed in the meeting room. If the function of automatically searching for the telephone number of another telephone set is provided, the telephone set 131 can automatically recognize the telephone number of the head office meeting room where the employee A is currently located. Therefore, in such a state, when an incoming call is received from the outside via the telephone line T, a process of automatically transferring the incoming call to the telephone in the head office meeting room can be executed. . Thus, the employee A can receive the phone addressed to the phone 131 while he / she is away from the phone at the Tokyo head office where he / she travels.

  In FIG. 5, the telephone line T is illustrated as a line separate from the network N. However, when the telephone 131 is an Internet telephone or the like, of course, the telephone line T is also a line via the network N. become.

<<< §5. Some variations of the present invention >>>
Here, some modified examples of the present invention are listed.

(1) Combined use of medium identification code and authentication information The information recording medium 201 shown in FIG. 2 is provided with an authentication information storage unit 22 and a medium identification code storage unit 24, respectively. Although an example of handling as separate information is shown, it is also possible to use authentication information stored in the authentication information storage unit 22 or a part thereof as a medium identification code, in which case the medium identification code is stored. The part 24 becomes unnecessary.

(2) Variations in location information In the example shown in Fig. 1, character strings indicating rough locations such as "Tokyo head office" and "Saitama factory" are used as location information indicating locations where individual electronic devices are installed. Although it is used, in practice it is preferable to use finer location information. For example, if you use location information in detail such as “Meeting room in Section 7 of the sales headquarters on the 3rd floor of the head office building” and “4th clean room on the 5th floor of the 4th building of the Saitama factory” You can grasp whereabouts by room. Of course, when using a printer or the like as an electronic device, the desk or table where the printer is installed, such as “No. 6 table in the 4th clean room on the 5th floor of the 4th building of the Saitama Factory” It is possible to grasp whereabouts.

  As the location information, it is not always necessary to use information consisting of character strings. For example, a device identification code such as “C101” can be used as location information instead of the character string “Tokyo head office”. is there. In this case, a correspondence table of the device identification code for the specific electronic device and the character string indicating the installation location of the electronic device is prepared, and the electronic device that plays the role of the receiver By referring to the table, the device identification code such as “C101” transmitted as the location information may be converted into a character string “Tokyo head office” and presented. The “location information” in the present application does not mean only information directly indicating the location as described above, but also includes information that can indirectly indicate the location by referring to some correspondence. For example, the electronic device can substitute its own device identification code as the location information, and in this case, the identification code storage unit 11 and the location information storage unit 12 can be shared by the same storage unit.

(3) Use of IP protocol / e-mail Recently, a network using the IP protocol is generally spread. As described above, when a network using the IP protocol is used as the network N, a device is used. An IP address is preferably used as the identification code.

  Further, when the location information transmitting unit 14 transmits location information to a specific electronic device registered as “report target”, it is possible to transmit information by e-mail.

(4) Location information transmitted multiple times For example, in the example shown in FIG. 1, employee A who is a staff member of the Chiba branch moves in the order of the Tokyo head office, the Yokohama branch, and the Saitama factory. , 102, and 104, the location information “Tokyo head office” is transmitted to the electronic device 103 that is “report target”, the location information “Yokohama branch office” is transmitted, and the “Saitama” The location information “factory” will be transmitted. In this way, when employees move from place to place, place information is sequentially transmitted to the electronic device that is the “report target” multiple times. For the location information transmitted a plurality of times as described above, the following two handling methods can be considered as the location information presentation unit 13.

  The first method is to present only the latest location information transmitted via the network. If this method is adopted, in the case of the above example, the display on the display screen of the electronic device 103 that is the “report target” changes from “I am currently in the Tokyo head office” to “I am currently in the Yokohama branch office”. It is changed to "I am in Saitama factory now". Of course, such a whereabouts display is not always accurate, and even if employee A is in the elevator of the Yokohama branch office, until the login procedure for the electronic device 102 is performed, “I am at the Tokyo head office. "Is displayed, but the location of the employee A who is constantly moving can be captured to some extent.

  In the case where multiple employees set the same electronic device as a “report target”, a medium identification code is sent together with location information. In such a case, each medium identification code is Only the latest location information needs to be presented. For example, if the latest location information for employee A is “Yokohama Branch” and the latest location information for employee B is “Saitama Factory”, then “Employee A is in Yokohama Branch. Employee B is in Saitama Factory” You can make a presentation like "

  Another handling method is a method in which a plurality of location information transmitted via the network are listed and presented in a time-series order. If this method is adopted, in the case of the above example, the display on the display screen of the electronic device 103 that is the “report target” will initially be “I am in Tokyo headquarters now”. It is changed to "I am now in the Yokohama branch via the Tokyo head office", and finally it is changed to "I am now in the Saitama factory via the Tokyo head office and the Yokohama branch". If such a presentation is performed, the movement route of the employee A can be grasped.

  In the case where multiple employees set the same electronic device as a “reporting target”, a medium identification code is transmitted together with location information. In such a case, for each individual medium identification code, What is necessary is just to enumerate and present several place information in the order according to each time series. Specifically, for example, “Employee A is at the Yokohama branch via the Tokyo head office. Employee B is at the Tokyo head office via the Saitama factory.” Good.

(5) Presenting Mode by the Location Information Presenting Unit The location information presenting unit 13 is a component having a function of storing the location information transmitted to itself via the network N and presenting this in a predetermined method. However, the presentation mode of the location information may be basically any type.

  However, when an electronic device for only presenting location information is registered as a “report target” as in the electronic bulletin board 121 described above, it is a dedicated job for the electronic device. Therefore, the location information may be always presented. However, when a normal personal computer is registered as “report target”, it is not preferable to always present the location information.

  Therefore, practically, when an electronic device such as a personal computer is registered as a “report target”, only when the user gives an instruction to present location information to the electronic device, It is preferable that the location information presentation unit presents location information on the display screen for the electronic device.

  Or, a general personal computer has a function of automatically entering a rest mode (a mode for switching from a normal screen display to a special screen display set in advance) when no operation input is made for a certain period of time. Yes. When entering such a rest mode, depending on the setting, the display screen can be darkened or a so-called screen saver program can be automatically activated. By using this function of the personal computer, the location information presenting section in the personal computer automatically presents the location information on the display screen for the personal computer when entering the rest mode. It is also possible. One such application is detailed in §6.

  In the embodiments described so far, the example in which the location information presentation unit 13 displays the location information on the display screen has been described. However, the presentation of the location information is not necessarily a visual presentation, and the audio It is also possible to present location information. For example, a message such as “I am at the Tokyo headquarters now” may be sent out by voice.

(6) Reset operation The location information presentation unit 13 temporarily stores location information transmitted to itself via a network and performs a process of presenting the location information in a predetermined method. It is preferable that the location information received in the past is deleted based on an instruction or a predetermined condition is satisfied, and thereafter a reset operation is performed so that the location information is not presented.

  For example, suppose employee A who has traveled to the Tokyo head office returns to his seat at the Chiba branch. In this case, the location information presenting unit 13 of the electronic device 103 that is the personal computer is in a state where the location information “Tokyo headquarters” is stored. Message is displayed. However, since employee A has already returned to his / her seat at this point, the location information stored in the location information presentation unit 13 is deleted, and the message “I am now at the Tokyo head office” is displayed. Should not be done.

  For this purpose, when a reset instruction is given from the user, a location information presenting unit is provided with a function of a reset operation that deletes the location information received in the past and prevents the location information from being presented thereafter. 13 may be prepared. Alternatively, a condition such as “perform reset operation when login procedure is performed” is set in advance, and the reset operation described above is automatically executed when the condition is satisfied. May be.

  As a condition for performing the reset operation, for example, it is possible to set a condition related to time such as “perform reset operation after 11:00 pm”. Then, every day at 11:00 pm, all electronic devices are reset all at once, and at the start of the next day, the system can always be started from the initial state. Alternatively, for the electronic device of the Chiba branch, a condition setting such as “reset operation is performed when the front gate of the Chiba branch is locked” may be performed. In this case, if all the staff of the Chiba branch return home and the guard locks the front gate, all the electronic devices in the Chiba branch will be reset at once.

  Note that the location information presenting unit 13 is not the only object of the reset operation. For example, the registration contents of the report target device registration unit 23 in the information recording medium 201 may be reset. In this case, a specific electronic device is provided with a function of deleting a predetermined device identification code recorded in the report target device registration unit 23 in the information recording medium based on a user instruction or a predetermined condition is established. Just keep it.

  For example, if you set a condition such as “Reset registration for reporting every Friday at 5pm,” you can communicate with a specific electronic device at 5pm every Friday. The device identification code recorded in the report target device registration unit 23 in the information recording medium is deleted. Of course, it is possible to set such that only a specific device identification code is selectively deleted. For example, among the device identification codes recorded in the report target device registration section 23, if only the first device identification code is left and all other codes are deleted, the “first report target” is set. Except for registrations, it will be automatically deleted every weekend.

(7) Other Modifications Although the basic embodiment and various modifications related to the present invention have been described above, the present invention is not limited to the above-described embodiments and modifications, and other than this. In addition, various embodiments can be implemented. In short, the basic concept of the present invention is that a plurality of fixing devices installed in different places, a portable mobile device having a function of communicating with the fixing device by bringing it into the communicable area of the fixing device, The mobile device is configured to record information indicating a specific fixed device (fixed device to be reported), and when each fixed device communicates with the mobile device, the mobile device The present invention is intended to perform a process of transmitting location information indicating its own location to a specific fixed device recorded in the present invention, and the present invention can be implemented in various modes without departing from this basic concept. It can be implemented.

<<< §6. Application example to screen lock absence display system >>
Finally, an application example in which the system according to the present invention is used as a “screen lock absence display system” will be described. Here, the “screen lock absence display system” means that when an employee who is engaged in work using a computer at a company leaves the office for work and leaves the room where the computer is installed, It is a system for displaying location information on the display of a personal computer that is locked to inform other employees.

  In a company, employees who work using personal computers may move to other rooms for meetings and meetings. In order to prevent unauthorized use of a personal computer by a third party when such a person is away from the desk, a technique for providing a screen lock function on the personal computer is known (for example, Japanese Patent Application Laid-Open No. 2003-167461, No. 2005-149443). The screen lock function in a personal computer is a function for not accepting an operation input for the original process until the unlocking process is performed by the user. The screen-locked personal computer cannot be used normally until the authorized user releases the lock, so security is maintained even when the user leaves the desk. That is, the screen-locked personal computer cannot be unlocked unless it is confirmed by the user's password input or biometric authentication. Usually, when an input operation on a personal computer is not performed for a predetermined set time, the setting is often made such that the screen is automatically locked. Therefore, if the person forgets to turn off the personal computer and leaves the desk for a long time for a meeting or the like, the user is automatically left with the screen locked.

  Further, in general, in a company or the like, when a destination is determined in advance, an employee is encouraged to leave after entering destination information on a destination entry board or the like. Then, even if you receive a phone call, you can respond by telling the destination you are filling in on the destination entry board to the other party or by contacting the person directly. Become. However, when a room for a meeting or a meeting is changed or when a user continuously participates in a plurality of meetings or meetings, it is impossible to specify in which room the person is currently located. Therefore, when urgent contact is desired, there is a problem that it is impossible to contact the person in a short time.

  Therefore, in the application example of the present invention described here, a destination display for the user of the personal computer is performed on the display of the personal computer having the screen lock function. That is, if the system according to this application example is introduced, when a user of a personal computer having a screen lock function leaves the room where the personal computer is installed, the destination information of the user is displayed on the screen of the personal computer with the screen locked. The destination information can be transmitted to others. Therefore, even when urgent communication is desired, it is possible to easily contact the person.

  FIG. 6 is a transparent perspective view showing an outline of an embodiment in which the present invention is applied to a screen lock absence display system. Here, for convenience of explanation, a simple model is shown in which two rooms A and B in which entrance / exit are managed are divided and arranged on the upper and lower floors as illustrated. An information processing apparatus 1 indicated by a broken line in the figure is configured by a dedicated computer for overall management of the absence display system, and is installed at an arbitrary place in the building. In addition, a communication network 2 (network) for the information processing apparatus 1 is stretched around necessary places in the rooms A and B. Here, it is assumed that the room A on the upper floor is a work room for a specific employee 3 to normally work, and the room B on the lower floor is a meeting room common to all employees.

  Each employee is provided with a contactless IC card (portable information recording medium) as an employee ID card. This specific employee 3 always has the contactless IC card 4 as an employee ID card. It shall be. In the memory of the non-contact IC card 4, when the card is issued, identification information of the employee 3 such as an employee ID is registered in advance.

  Management of entering and leaving the rooms A and B is performed by using the IC card 4. Therefore, in the rooms A and B, IC card readers 5A and 5B (attached toward the outside of the room) which are reading devices for reading the identification information stored in the IC card 4, and for leaving the room IC card readers 6A and 6B (attached toward the inside of the room), which are readers, are provided. That is, these IC card readers are installed in the vicinity of the entrances and exits of each room, and are reading devices that read identification information recorded on the non-contact IC card when entering or leaving each room.

  When the employee 3 enters and exits the doors 7A and 7B in the rooms A and B, authentication is performed by bringing the non-contact IC card 4 close to the IC card readers 5A, 5B, 6A and 6B, and the doors 7A and 7B are unlocked. Need to lock. The door locking / unlocking devices 8A and 8B are devices provided for controlling the locking states of the doors 7A and 7B, respectively, and based on the identification information read by the reading devices of the rooms A and B, the doors of the rooms Controls the locked state of. Since the doors 7A and 7B are normally locked by the door locking / unlocking devices 8A and 8B, a third party cannot enter or leave the room illegally.

  In the room A, a work desk for the employee 3 is arranged (not shown), and a personal computer 9 used by the employee 3 is installed on the desk. The employee 3 usually sits at his / her desk in the room A and works using his / her own personal computer 9. In the figure, only the personal computer 9 for the employee 3 is shown. However, in this room A, since a plurality of employees perform work using the given personal computers, in actuality, PCs for employees are installed. Each PC has a screen lock function that does not accept the operation input for the original processing until the unlocking process is performed by the user, and the location information (explained later) received from the outside is displayed during screen lock. And a function to display above.

  As shown in the figure, the IC card readers 5A and 5B that are the reading devices for entering the room, the IC card readers 6A and 6B that are the reading devices for leaving the room, and the door locking / unlocking devices 8A and 8B are respectively connected to the information processing device by the communication network 2. 1 is connected. A personal computer 9 provided in the room A and a personal computer for other employees (not shown) are also connected to the information processing apparatus 1 through the communication network 2. Based on the identification information read by the reading device in the specific room, the information processing apparatus 1 specifies a personal computer (a personal computer to be reported) corresponding to the identification information, and the room information indicating the specific room is It has a function to transmit as location information to a personal computer.

  When the employee 3 enters the room A or B, first, the identification information stored in the non-contact IC card 4 needs to be read by the IC card reader 5A or 5B. The read identification information is transmitted to the information processing apparatus 1 and authentication is performed as to whether or not the identification information is correct. When the information processing apparatus 1 obtains an authentication result indicating correct identification information, a door unlocking instruction signal is transmitted to the door locking / unlocking apparatus 8A or 8B, and the door 7A or 7B is unlocked. Is called. Similarly, when the employee 3 leaves the room A or B, first, the identification information stored in the non-contact IC card 4 needs to be read by the IC card reader 6A or 6B. The read identification information is transmitted to the information processing apparatus 1 and authentication is performed as to whether or not the identification information is correct. When the information processing apparatus 1 obtains an authentication result indicating correct identification information, a door unlocking instruction signal is transmitted to the door locking / unlocking apparatus 8A or 8B, and the door 7A or 7B is unlocked. Is called.

  Of course, employees other than the employee 3 similarly enter and leave each room using their own non-contact IC card in which unique identification information is written. When such entry / exit management is performed, the information processing apparatus 1 can grasp who has entered each room A and B and who has left, and further, information necessary for each employee's personal computer. Can be sent. That is, the information processing apparatus 1 performs an authentication process based on information received from the IC card readers 5A and 5B that are reading devices for entering the room and the IC card readers 6A and 6B that are reading devices for leaving the room, and performs door locking / unlocking. In addition to transmitting a locking / unlocking instruction signal to the devices 8A and 8B, for example, to the personal computer 9 installed in the room A, the location information when the employee 3 who is the user of the personal computer 9 is away is sent. Can be processed.

  FIG. 7 is a block diagram of components involved in information processing in the screen lock absence display system shown in FIG. As illustrated, the information processing apparatus 1 includes an authentication unit 1A, an unlock signal transmission unit 1B, a storage unit 1C, a room information transmission unit 1D, a control unit 1E, an employee information database 1F, and an equipment information database 1G. . The control unit 1E performs overall control of processing performed in the information processing apparatus 1, and the storage unit 1C is used as a temporary data storage place in this processing.

  The employee information database 1F includes identification information (employee ID, etc.) stored in a contactless IC card distributed to each employee, personal information such as the employee's name and the door given to the employee. Information indicating the unlocking authority is registered in association with each other. Therefore, the authentication unit 1A can check the presence / absence of the authority to unlock the door of the room by referring to the employee information database 1F based on the identification information read by the reading device of the specific room. If the employee indicated by the identification information has the authority to unlock the room, it can be determined that the authentication has succeeded. The unlock signal transmitting means 1B transmits an unlock signal to the door locking / unlocking device in the room when the correct authentication result by the authenticating means 1A is obtained. The door locking / unlocking devices 8A and 8B perform unlocking when receiving the unlocking signal.

  On the other hand, in the equipment information database 1G, a personal computer management number, which is information unique to each equipment, is stored in advance so that a personal computer that is equipment installed in each room can be associated with a user. Identification information such as the employee ID of the user is registered in association with each other. As described above, identification information for identifying an employee such as an employee ID is recorded in the non-contact IC card. However, the equipment information database 1G includes an individual employee ID and a specific personal computer (the employee ID). It is a function that associates the personal computer used by the employee identified by (1) with the identification information such as the employee ID read from the non-contact IC card, and the location (reporting target) of the employee's location information You can identify the PC that should be.

  On the left side of FIG. 7, electronic devices provided in the rooms A and B are shown as a block diagram. That is, the IC card reader 5A is installed on the door entrance side (outside the room) of the room A, and the IC card reader 6A is installed on the door exit side (inside the room). A state of wireless communication with the IC card 4 is shown as a block diagram. In the room A, a door locking / unlocking device 8A for controlling the locking / unlocking of the door 7A is installed. Similarly, an IC card reader 5B is installed on the door entrance side (outside the room) of the room B, and an IC card reader 6B is installed on the door exit side (inside the room). A state of wireless communication with the contact IC card 4 is shown as a block diagram. In the room B, a door locking / unlocking device 8B for controlling the locking / unlocking of the door 7B is installed.

  On the other hand, on the right side of FIG. 7, a personal computer 9 installed in the room A is shown as a block diagram. As described above, a personal computer for each employee is also installed in the room A, but the illustration and description are omitted here.

  Next, the processing procedure of the screen lock absence display system will be described based on the flowcharts shown in FIGS. Here, in order to explain this processing procedure, as an example, a specific employee 3 comes to the office, enters the room A where the personal computer 9 is placed, has a seat, works for a while, and then has a meeting. Next, the flow of processing in the case of leaving the room A and moving to the room B below the floor will be described below.

  First, the employee 3 who came to work in the morning brings the non-contact IC card 4 close to the IC card reader 5A on the entrance side of the room A, and reads the employee ID stored in the non-contact IC card 4 (step S1). The employee ID read by the IC card reader 5A is transmitted to the information processing apparatus 1 (step S2). The information processing apparatus 1 performs an authentication process on the received employee ID based on information registered in the employee information database 1F (step S3). When correct authentication is performed in this authentication process, an instruction signal for unlocking the door is transmitted from the information processing apparatus 1 to the door locking / unlocking apparatus 8A (step S4). When receiving the instruction signal, the door locking / unlocking device 8A unlocks the door 7A (step S5). Thereby, the employee 3 can enter the room A by opening the door 7A. The employee 3 who has entered the room A activates the personal computer 9 and performs work using the personal computer 9 (step S6). On the other hand, if the authentication process fails in step S3, the process is terminated without transmitting an instruction signal for unlocking the door 7A from the information processing apparatus 1 to the door locking / unlocking apparatus 8A. The

  Next, consider a case where the employee 3 moves from the room A to the room B in order to make a meeting in the middle of work using the personal computer 9. In this case, the employee 3 brings the non-contact IC card 4 close to the IC card reader 6A on the exit side of the room A, and reads the employee ID stored in the non-contact IC card 4 (step S7). The employee ID read by the IC card reader 6A is transmitted to the information processing apparatus 1 (step S8). The information processing apparatus 1 performs an authentication process on the received employee ID based on information registered in the employee information database 1F (step S9). When correct authentication is performed in this authentication process, the information processing apparatus 1 transmits an instruction signal for unlocking the door to the door locking / unlocking apparatus 8A (step S10). When the door locking / unlocking device 8A receives this instruction signal, the door locking / unlocking device 8A unlocks the door 7A (step S11). Thereby, the employee 3 can leave the room A by opening the door 7A. Note that the personal computer 9 whose work has been interrupted automatically activates the screen lock after a preset time has elapsed, and becomes unusable by a third party.

  Now, the employee 3 who has left the room A heads downstairs and comes to the front of the room B where the meeting is scheduled. Then, the non-contact IC card 4 is brought close to the IC card reader 5B on the entrance side of the room B, and the employee ID stored in the non-contact IC card 4 is read (step S12). The employee ID read by the IC card reader 5B is transmitted to the information processing apparatus 1 (step S13). The information processing apparatus 1 performs an authentication process on the received employee ID based on information registered in the employee information database 1F (step S14). When correct authentication is performed in this authentication process, the information processing apparatus 1 transmits an instruction signal for unlocking the door to the door locking / unlocking apparatus 8B (step S15). When receiving the instruction signal, the door locking / unlocking device 8B unlocks the door 7B (step S16). Thereby, the employee 3 can enter the room B by opening the door 7B. On the other hand, if the authentication process fails in step S14, the process is terminated without transmitting an instruction signal for unlocking the door 7B from the information processing apparatus 1 to the door locking / unlocking apparatus 8B. The

  By the way, when the authentication process in step S14 is successful, the information processing apparatus 1 can obtain information that “the employee 3 has entered the room B”. Therefore, a process of notifying the entry information to the personal computer 9 of the employee 3 is performed. Specifically, based on the employee ID received from the IC card reader 5B, the information processing apparatus 1 recognizes the personal computer management number registered in the equipment information database 1G in association with the employee ID, 3 specifies the personal computer 9 (report target) that is always used. Then, a message (location information) indicating that the employee 3 is entering the room B is transmitted to the personal computer 9 (step S17).

  The personal computer 9 has a function of displaying such a message (location information) on the display when the screen is locked. Then, a message saying “I am in room B” (a message such as “I am currently in room B”) may be automatically displayed on the display of the personal computer 9 when the screen is locked. (Step S18). Therefore, even when a phone call for employee 3 is received on the phone in room A, a colleague of employee 3 in room A sees the message displayed on the display of personal computer 9 to Since it is possible to confirm that 3 is currently in room B, an appropriate response can be made to the telephone. For example, if it is necessary to contact the employee 3 immediately, the room B may be called.

  Next, let us consider a case where the employee 3 who has finished the meeting in the room B goes out for lunch. In this case, the employee 3 brings the non-contact IC card 4 close to the IC card reader 6B on the exit side of the room B, and reads the employee ID stored in the non-contact IC card 4 (step S19). The employee ID read by the IC card reader 6B is transmitted to the information processing apparatus 1 (step S20). The information processing apparatus 1 performs an authentication process on the received employee ID based on information registered in the employee information database 1F (step S21). If correct authentication is performed in this authentication process, an instruction signal for unlocking the door is transmitted from the information processing device 1 to the door locking / unlocking device 8B (step S22). Upon receiving this instruction signal, the door locking / unlocking device 8B unlocks the door 7B (step S23). Thereby, the employee 3 can leave the room B by opening the door 7B. On the other hand, if the authentication process fails in step S21, the process is terminated without transmitting an instruction signal for unlocking the door 7B from the information processing apparatus 1 to the door locking / unlocking apparatus 8B. The

  When the authentication process in step S21 is successful, the information processing apparatus 1 can obtain information that “the employee 3 has left the room B”. Therefore, this time, a process of notifying the leaving information to the personal computer 9 of the employee 3 is performed. That is, based on the employee ID received from the IC card reader 6B, the information processing apparatus 1 recognizes the personal computer management number registered in the equipment information database 1G in relation to the employee ID, and the employee 3 always Identify the personal computer 9 (reporting target) in use. Then, a message to the effect that the employee 3 is leaving the room B is transmitted to the personal computer 9 (step S24).

  Upon receiving such a message, the personal computer 9 automatically displays on the display a message stating that “I am leaving room B” (a message such as “I have already left room B” may be displayed). (Step S25). Therefore, a colleague in the room A can recognize that the employee 3 has already left the room B.

  Thereafter, when the employee 3 enters another room C (not shown), a message such as “I entered the room C” is displayed. When the employee 3 leaves the room C, the “room C” Will be displayed. " Of course, if the history of messages received in the past is displayed on the display of the PC 9, “I entered room B” / “I left room B” / “I entered room C” The action history of the employee 3 can be shown in order, such as “I left room C”. Further, if the information processing device 1 has a function for recognizing the current time, a message including the time when the user enters or leaves the room is transmitted, and a message “Room B at 10:32” is displayed on the display of the personal computer 9. It is also possible to display the time at the same time.

  In this way, even if the personal computer 9 is screen-locked, the location of the employee 3 is sequentially displayed on the display, so that a colleague in the room A can change the location of the employee 3. Can be recognized. In the above description, only the processing operation related to one employee 3 has been described. However, the same system is adopted for all employees who work on a personal computer, so that the location information of employees who have left their seats can be obtained. You can display the information on the employee's computer display to let other employees know your contact information.

  In the above description, the employee ID for identifying the employee 3 is recorded as identification information in the non-contact IC card 4, but the identification information recorded in the non-contact IC card is not necessarily limited to the employee ( In other words, it is not necessary to make the information specifying the personal computer user), and it may be the information specifying the personal computer itself. For example, if a personal computer management number for identifying the personal computer 9 of the employee 3 or an IP address is recorded in the non-contact IC card 4 as identification information, the information processing apparatus 1 becomes a transmission destination of location information. It is possible to directly recognize that the personal computer (report target) is the personal computer 9. Further, the personal computer 9 itself does not necessarily have to be installed in a room in which entry / exit is managed.

  After all, in the screen lock absence display system described here, even if a PC user leaves the office, the information on the person's whereabouts is displayed on the screen locked PC, so the person can be contacted urgently. You will be able to contact the person even if you need to do so. Also, an entrance reader that reads identification information recorded on the information recording medium when entering each room, and an exit for reading the identification information recorded on the information recording medium when leaving each room. The information processing device 1 transmits location information indicating entry into the room when the reading device for reading the room reads the identification information, and the reading device for leaving the room identifies the reading device. When the information is read, the location information indicating the exit to the room can be transmitted, so that whether the person has entered the specific room or has exited is displayed on the display of the personal computer. Furthermore, since this screen lock absence display system uses a non-contact IC card and an IC card reader, even if there is an ID card such as an employee ID card already used, It can be used in combination.

  Finally, a very practical device for the screen lock absence display system described here will be described. In the above-described example, it has been described that when an operation input to the personal computer 9 is not performed for a predetermined set time, the screen lock is automatically activated and the third party cannot use the screen lock. However, for practical purposes, it is preferable that the specification is such that the screen lock is automatically activated without waiting for the passage of time when the employee 3 suspends the work on the personal computer 9 and leaves the room A. . In such a specification, when the employee 3 leaves the room A in which the personal computer 9 is installed, the screen lock of the personal computer 9 is automatically activated when the exit is detected. Such a specification is that an IC card reader 6A provided near the exit of the room A in which the personal computer 9 is installed (a reading device for reading out the identification information from the information recording medium 4 when leaving the room A). This can be realized by using.

  That is, when the employee 3 leaves the room A, the non-contact IC card 4 is brought close to the IC card reader 6A on the exit side of the room A, and the employee ID stored in the non-contact IC card 4 is read. Do work. Then, the employee ID is transmitted to the information processing apparatus 1. Here, the information processing apparatus 1 performs an authentication process based on the information registered in the employee information database 1F for the received employee ID. If the authentication is successful, an unlock signal is sent to the door locking / unlocking apparatus 8A. Will be sent. At this time, the information processing apparatus 1 can recognize that the personal computer of the employee 3 is the personal computer 9 based on the identification information read by the non-contact IC card 4, that is, the employee ID of the employee 3.

  Thus, when a specific employee leaves the specific room as described above, if it is found that the personal computer of the specific employee is installed in the specific room, the information processing apparatus 1 Then, a process for starting the screen lock of the personal computer may be performed. Specifically, a command signal instructing activation of the screen lock is transmitted from the information processing apparatus 1 to the personal computer 9. If such a command signal is given to the personal computer 9 side, a mechanism for automatically starting screen lock is prepared, and the personal computer 9 automatically screens according to the command signal from the information processing apparatus 1. Become locked. By adopting such a mechanism, when a person leaves the room where the personal computer he / she uses is installed, the screen lock of the personal computer is automatically activated, preventing unauthorized use by a third party. An accompanying effect that can be obtained is obtained. In this case, when the person leaves the room A and the screen lock of the personal computer 9 is activated, an out-of-office message is displayed on the screen of the personal computer 9 for the time being. When the person's whereabouts can be detected, a destination display such as “Now, XX is in room B” may be displayed.
