Description

  The present invention relates to a destination presentation system, and more particularly, to a destination presentation system using electronic devices connected to each other via a network.

  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. By using this system, it is possible to immediately display the destination and location of other members on a terminal device such as a personal computer for confirmation.

  In the case of a destination presentation system for homes or small and medium-sized businesses, the number of members that are the target of destination presentation is relatively small, and the destination places are often limited. However, when it comes to large corporations and large organizations, there are a considerable number of members and destinations. For this reason, even if the destination information about all members is collected by some system, if all the information is presented to all persons, the practicality is impaired. In general, since the destination of a specific member is an interest of only a specific person, a system in which destination information of the specific member is efficiently presented to the specific person is desired. ing.

  As a technique for extracting only the information that one wants from a large number of information, a technique called search is usually used. Therefore, even in the destination presentation system, it is possible to extract and display only the destination information of a specific member by using the search method. For example, if you have a system that collects destination information for all members and you want to know the destination of a specific member called “Ichiro Suzuki”, you can search for “Ichiro Suzuki” by searching for the name or employee code. It is possible to extract and present only the destination information related to “”. However, as long as such a method is adopted, an extra work called a search work is required, so convenience is inevitably lowered.

  On the other hand, for example, a method is adopted in which a device as a report destination is determined in advance for each individual member, and the destination information of the specific member is displayed only on the screen of the specific device as the report destination. It is also possible. However, in this method, since the destination display is performed only for a predetermined specific report destination, it is difficult to take a flexible measure for appropriately changing the report destination.

  Therefore, an object of the present invention is to provide a destination presentation system capable of efficiently presenting information related to a destination of a specific member to an appropriate place where the information is predicted to be required.

Perform the process. For this reason, since the route history indicating the subsequent steps concerning the members who visited in the past is selected and presented to each terminal device, information relating to the destination of the specific member is required. It is possible to present it efficiently at a place where it is expected to be (a place where you have visited in the past).

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

<<< §1. Basic configuration and basic operation principle >>>
First, the basic configuration and basic operation principle of the destination presentation system according to the present invention will be described. FIG. 1 is a block diagram showing a basic configuration of a destination presentation system according to an embodiment of the present invention. The essential components of the present invention are a plurality of terminal devices installed at different locations and connected to each other via a network, and a plurality of portable information recording media. In FIG. 1, for convenience of explanation, a simple example using a total of 13 terminal devices T11 to T43 and a total of 5 information recording media M1 to M5 is shown. It can be implemented using an information recording medium.

  Each terminal device T11-T43 is mutually connected by the network N as shown in the figure. Here, this destination presentation system is used to present the destinations of members of employees of a company, and the company has facilities such as Tokyo headquarters, Yokohama branch, Chiba branch, and Saitama factory. And Furthermore, the terminal devices T11 to T14 are devices installed in the 101st to 104th rooms of the Tokyo head office, respectively, and the terminal devices T21 to T23 are devices installed in the 201st to 203th rooms of the Yokohama branch office, respectively. Terminal devices T31 to T33 are devices installed in rooms 301 to 303 of the Chiba headquarters, respectively, and terminal devices T41 to T43 are devices installed in rooms 401 to 403 of the Saitama factory, respectively. (In this example, a 2-digit numerical value obtained by deleting the central digit 0 of the 3-digit numerical value indicated by the number of each room corresponds to a code of T or less of the terminal device installed in the room).

  The detailed internal configuration of each terminal device T11 to T43 will be described in §2. The illustrated electronic bulletin board T00 and the management device T99 are to be special terminal devices, and their configurations and functions will be described in §4.

  On the other hand, each of the information recording media M1 to M5 is a portable medium that is given to a specific member, and has a unique medium identification code recorded therein. Here, for convenience of explanation, it is assumed that the medium identification codes recorded on the information recording media M1 to M5 are CC001 to CC005, respectively, and each medium is “Ichiro Suzuki” who is an employee of the company as shown in the figure. -It shall be distributed as an employee ID card to Goro Takahashi. The medium identification codes CC001 to CC005 may be recorded by any method as long as each terminal device T11 to T43 is readable.

  In this destination presentation system, each terminal device T11 to T43 fulfills two functions. A 1st function is a function as a transmission source which alert | reports to the other terminal device that the said member stopped when the specific member stopped at the installation place. For example, when the employee “Ichiro Suzuki” stopped by the Tokyo head office, the 101st room, the terminal device T11 installed in the Tokyo head office, the 101st room, said that “Ichiro Suzuki stopped by the Tokyo head office, the 101st room”. It has a function to notify terminal devices T12 to T43. In other words, when each member stops at his / her installation location, each terminal device uses other information (hereinafter referred to as route report information) for reporting “who stopped where”. It has the function to transmit with respect to the terminal device.

  On the other hand, a second function of each terminal device is a function of presenting a route history (a history indicating where the user has stopped) for a specific member. Here, an important point is that “a member who has visited in the past” is selected as the “specific member” for whom the route history is presented. As described above, when each terminal device presents the destinations of all members, the viewer needs to search for a desired member by name or the like, and the browsing work becomes complicated. I have to be. The unique point of view of the present invention is that, when a certain member stops at a certain place, if the destination of the specific member is presented at the stopping place, a very effective destination presentation becomes possible. It is in that point.

  For example, consider the following example in the system shown in FIG. Suppose that the employee “Ichiro Suzuki” is a staff member of the Chiba branch office and that his / her seat is located in room 301 of the Chiba branch office. And “Ichiro Suzuki” who came to work at 9:00 am first prepared for work at his seat, then traveled to the Tokyo head office in the morning, had a meeting in room 102, and had a meeting in room 104 Suppose you attend. Then, in the afternoon, let's assume that you meet a customer in the 203rd room of the Yokohama branch, delivered materials to the 402th room in the Saitama factory in the evening, and returned to your seat in the 301st room of the Chiba branch.

  After all, the movement route of “Ichiro Suzuki” on this day becomes the route of Chiba branch office room 301 → Tokyo head office room 102 → same room 104 → Yokohama branch room 203 → Saitama factory room 402 → Chiba branch room 301. The room will be the stop for “Ichiro Suzuki” on the day. Here, considering the location of the staff who wants to know the destination of “Ichiro Suzuki” who took such a movement route, it is highly probable that they are concentrated in these stops. Easy to understand. “Ichiro Suzuki” should normally meet someone inside or outside the company at each stop, and the visitor is naturally engaged in operations related to “Ichiro Suzuki”. Conceivable. Therefore, it is extremely reasonable to select the stop of “Ichiro Suzuki” as the place where the destination of “Ichiro Suzuki” is presented. There is a high possibility that a visitor with “Ichiro Suzuki” is staying at the stop. If you show the destination of “Ichiro Suzuki” to the stop, you can present useful information to the visitor. It can be carried out.

  Based on such an idea, in the system according to the present invention, each of the terminal devices T11 to T43 has a function of presenting a subsequent route history for a specific member who has stopped in the past. For example, in the case of the above example, “Ichiro Suzuki” stops in the Chiba branch office No. 301 room at 9 o'clock in the morning, and the terminal device T31 is presented with a subsequent step of “Ichiro Suzuki”. That is, when “Ichiro Suzuki” arrives at the Tokyo headquarters room 102, it is presented as “→ Tokyo headquarters room 102”, and when it arrives at the 104th room, “→ Tokyo headquarters room 102 → same 104”. Room No. "is presented, and when it arrives at Yokohama Branch No. 203 in the afternoon, it is presented as" → Tokyo Head Office No. 102 Room → No. 104 Room → Yokohama Branch No. 203 Room ". If a colleague belonging to the same department as “Ichiro Suzuki” resides in the Chiba branch office No. 301, it is very useful if such a route history of “Ichiro Suzuki” is presented to the terminal device T31. .

  On the other hand, since “Ichiro Suzuki” stopped in the morning at room 102 in the Tokyo head office, the terminal device T11 is presented with a footstep for “Ichiro Suzuki” thereafter. That is, when arriving at Tokyo headquarters room 104, “→ Tokyo headquarters room 104” is presented, and when arriving at Yokohama branch office 203 in the afternoon, “→ Tokyo headquarters room 104 → Yokohama office room 203”. Is presented, and when it arrives at the Saitama Factory No. 402 in the evening, it is presented as “→ Tokyo head office No. 104 room → Yokohama branch office No. 203 room → Saitama factory No. 402 room”. If another staff member who had a meeting with “Ichiro Suzuki” stayed in the Tokyo headquarters room 102, it would be very useful if such a route history of “Ichiro Suzuki” was presented to the terminal device T11. is there.

  As described above, the basic principle of the present invention is that information on the subsequent destination of the specific member is presented on the terminal device installed at the stop of the specific member. If the destination presentation based on such a basic principle is performed, it is possible to achieve the object of the present invention to efficiently present the destination information of a specific member to the appropriate place where the information is necessary. Of course, in fact, there is a possibility that the staff of the department that is not visited by “Ichiro Suzuki” wants to know the location of “Ichiro Suzuki”, and the system according to the present invention meets such a request. It is not possible. However, as described above, many of the staff members who want to know the destination of “Ichiro Suzuki” are highly likely to be staff members at the destination of “Ichiro Suzuki”, and from a global perspective, the system according to the present invention. Is sufficiently functional for practical use.

  When constructing the destination presentation system according to the present invention, first, terminal devices T11 to T43 as shown in the figure need to be installed at predetermined locations. On the other hand, portable information recording media M1 to M5 each recording a unique medium identification code are prepared, and in the case of the example described here, this is given to each member of this company. Try to have it. Then, when each member stops at a specific location, the terminal device installed at the specific location reads the medium identification code recorded on the information recording medium possessed by the member. I will tell you.

  Eventually, when a specific member comes to the installation location of the specific terminal device, the specific terminal device reads the medium identification code recorded on the information recording medium possessed by the specific member. . The read medium identification code is used as a code indicating the specific member, and is registered in the specific terminal device. This registration has a meaning indicating that a specific member indicated by the medium identification code has stopped at the installation location of the specific terminal device.

  In addition, the specific terminal device transmits route report information including “read medium identification code” and “location information directly or indirectly indicating its installation location” to other terminal devices (other than itself). To all terminal devices). Here, it can be said that this route report information is information indicating “who (a specific member indicated by the read medium identification code) has stopped by” (where the installation location indicated by the location information). In addition, the route report information is transmitted all at once by a so-called “broadcast” method directed to all other terminal devices connected to the network N, not a method of designating a specific communication destination.

  Note that “broadcast” in the TCP / IP protocol is used as a term indicating simultaneous transmission within the same network separated by routers, but “broadcast” in this application is not necessarily separated by routers. It does not mean transmission within the specified range, but means simultaneous transmission to all other terminal devices that constitute the system.

  On the other hand, each terminal device, when route report information is transmitted from another terminal device by the “broadcast” method, first receives this, and then the medium identification code included in the “received route report information” It is determined whether or not has been registered in the past. This determination is ultimately a determination of whether or not the “received route report information” relates to a member who has visited in the past. If registered, the location information included in the “received route report information” is stored as a route history related to the medium identification code, and the stored route is stored as necessary. A process of presenting a part or all of the history is performed. In other words, when the “received route report information” relates to a member who has visited in the past, a process of accumulating and presenting it is performed, and when it is related to other members, this is indicated. Processing to discard is performed. As a result, only the route history indicating the subsequent steps regarding the members who visited in the past is selected and presented to each terminal device.

<<< §2. Internal configuration of terminal device >>
Next, a specific internal configuration example of each of the terminal devices T11 to T43 illustrated in FIG. 1 will be described with reference to the block diagram of FIG. A terminal device T composed of a portion surrounded by an alternate long and short dash line in FIG. 2 represents any one of the terminal devices T11 to T43 shown in FIG. 1, and the information recording medium M shown in FIG. 2 is shown in FIG. Any one of the information recording media M1 to M5 is shown. As shown in the figure, the terminal device T is connected to the network N, and can communicate with another terminal device (not shown) via the network N. As described above, a unique medium identification code for identifying the information recording medium is recorded in the information recording medium M. FIG. 2 shows an example in which a medium identification code “CC001” is recorded (an example in the case of the information recording medium M1 shown in FIG. 1).

  As illustrated, the terminal device T includes a code reading unit 110, a code registration unit 120, a route history storage unit 130, a location information storage unit 140, a route report information transmission unit 150, a route report information reception unit 160, and a route history writing unit. 170, a route history presentation unit 180, and a route history deletion unit 190. However, as will be described later, the terminal device T is actually a device constituted by an electronic device such as a personal computer, and each of these blocks is constructed by hardware and software for the electronic device. It will be a component.

  The code reading unit 110 is a component having a function of reading the medium identification code recorded on the information recording medium M, and the code registration unit 120 reads the code when the code reading unit 110 performs reading. It is a component that performs processing for registering the issued medium identification code in the path history storage unit 130. Further, as will be described later, the route history storage unit 130 is a component that stores the route history of the “specific information recording medium (registered information recording medium)” reported via the network N. Can be configured as a memory area for a computer or a storage area of a storage device.

  FIG. 2 shows a state where the medium identification code “CC001” is read from the information recording medium M by the code reading unit 110 and is registered in the path history storage unit 130 by the code registration unit 120. . Here, registering the medium identification code means not only recording the code in the path history storage unit 130 but also preparing for storing the path history related to the medium identification code. In the route history storage unit 130 shown in the figure, a table with the headings “medium identification code” and “route history” is shown. This indicates that a history storage column is secured. Specifically, in the example shown in the figure, a state in which five path history storage fields (blanks at present) are secured is shown in relation to the medium identification code “CC001”, and the medium identification code “CC001” is shown. "Serves as a heading for the five storage fields.

  Of course, the illustrated table shows the storage status of the path history related to a specific medium identification code so that it can be easily grasped visually. In practice, the path history is not necessarily stored in such a table format. There is no need. As long as each path history can be stored as data relating to a specific medium identification code, any data storage format in the path history storage unit 130 may be used.

  The location information storage unit 140 is a component that stores location information that directly or indirectly indicates the installation location of itself (the terminal device T itself). In the figure, an example in which data consisting of a character string “Chiba branch office 301 room” is stored as location information in the location information storage unit 140 (an example in which the terminal device T is the terminal device T31 shown in FIG. 1). )It is shown. In this case, the character string “Chiba branch office No. 301” is location information directly indicating the installation location of the terminal device T31. As will be described later, the location information indirectly indicates the installation location. Information may be used. Of course, the location information storage unit 140 in the terminal device T11 installed in the 101st room of the Tokyo head office stores data consisting of the character string “Tokyo 101st room”.

  The route report information transmission unit 150 includes a route report including the medium identification code read when the code reading unit 110 performs reading and the location information stored in the location information storage unit 140. Information is created, and the route report information is transmitted to another terminal device via the network N. In the upper right of FIG. 2, as a specific example of the route report information, an example including a medium identification code “CC001” and location information “Chiba branch office 301” is shown. As described above, the route report information is transmitted all at once by a so-called “broadcast” method directed to all other terminal devices connected to the network N.

  The route report information is information indicating “who has stopped where”, and in the case of the illustrated example, “the owner of the information recording medium specified by the medium identification code“ CC001 ”is the location information“ Chiba branch office 301 ”. "I stopped by the place specified by". That is, an operation in which a person possessing “information recording medium M on which medium identification code“ CC001 ”is recorded” causes terminal device T and information recording medium M to communicate and read medium identification code “CC001”. The route report information indicating that “this person has stopped at the room 301 of the Chiba branch office” is transmitted all at once to the other terminal devices by the “broadcast” method.

  On the other hand, the route report information receiving unit 160 receives the route report information from another terminal device (not shown in FIG. 2) via the network N, and receives the route report information. A process of handing over to the embedding unit 170 is performed. Then, the route history writing unit 170 determines whether or not the medium identification code included in the “received route report information” is registered in the route history storage unit 130. Performs a process of writing the location information included in the “received route report information” as a new route history in the storage field related to the medium identification code. For example, in the example shown in FIG. 2, since the medium identification code “CC001” is registered in the route history storage unit 130, the medium identification code included in the “received route report information” is “CC001. ”, The location information included in the“ received route report information ”is written as a new route history in the storage field corresponding to the medium identification code“ CC001 ”. . When route report information including other medium identification codes is received, it is discarded as it is.

  When a presentation instruction is given from the outside, or when a predetermined presentation condition set in advance is satisfied, the route history presenting unit 180 is a part of the route history stored in the route history storage unit 130 or Process to present all. Although a specific presentation example will be described later, the route history stored in the route history storage unit 130 is a subsequent route history for a member who has visited in the past. The unit 180 can selectively present a route history for members who have visited in the past.

  The route history deletion unit 190 deletes part or all of the stored contents of the route history storage unit 130 when a deletion instruction is given from the outside or when a predetermined deletion condition set in advance is satisfied. Process. The route history deletion unit 190 is not an essential component in the operating principle of the system according to the present invention, but in practice, the route history stored in the route history storage unit 130 is deleted as necessary. It is preferable to provide it as one component in the terminal device T so that it can be performed.

<<< §3. Specific operation example of destination presentation system >>
Next, a specific operation example of this system will be described on the assumption that each of the terminal devices T11 to T43 in the destination presentation system shown in FIG. 1 has the same configuration as the terminal device T shown in FIG. Keep it. Here, as illustrated in §1, Chiba branch staff “Ichiro Suzuki” possesses the information recording medium M1 in which the medium identification code “CC001” is recorded, and at 9:00 am, the Chiba branch office 301 room. Let's consider the case of moving to Chiba branch office 301 room → Tokyo head office 102 room → 104 room 104 → Yokohama branch office 203 room → Saitama factory 402 room → Chiba branch office 301 room.

  FIG. 3 is a diagram showing an initial state of the route history stored in the route history storage unit 130 of each of the terminal devices T11 to T43 shown in FIG. Here, for convenience of explanation, the states in the route history storage unit 130 of the terminal devices T31, T12, T14, T23, and T42 (all of which are installed in the room where “Ichiro Suzuki” visited) are independent of each other. The states in the route history storage unit 130 of other terminal devices are shown in a common table. In the initial state shown in FIG. 3, all tables are blank.

  Now, when “Ichiro Suzuki” enters the Chiba branch office No. 301 room at 9:00 am and accesses the information recording medium M1 possessed by the terminal device T31, the code reading unit 110 reads the medium identification code “CC001”. Then, it is registered in the route history storage unit 130 by the code registration unit 120. This registration indicates that “Ichiro Suzuki” has visited Chiba Branch Office 301. FIG. 4 is a diagram showing a change state of the route history at this time. The state where the medium identification code “CC001” is registered only in the terminal device T31 installed in the Chiba branch office No. 301 room is shown. At this time, the route report information transmitting unit 150 in the terminal device T31 reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Chiba branch office 301 room”). The route report information including the character string) is created and broadcasted via the network N. However, at this time, since there is no terminal device registered with the medium identification code “CC001” other than the terminal device T31, the route report information broadcasted is discarded in other terminal devices. .

  Subsequently, when “Ichiro Suzuki” makes a business trip to the Tokyo head office, enters the room 102 of the Tokyo head office, and accesses the information recording medium M1 possessed to the terminal device T12, the code in the terminal device T12 is now turned on. The medium identification code “CC001” is read by the reading unit 110 and registered in the path history storage unit 130 by the code registration unit 120. This registration indicates that “Ichiro Suzuki” has visited the Tokyo head office, Room 102. At this time, the route report information transmission unit 150 in the terminal device T12 also reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Tokyo head office 102 The route report information including the character string “No. Room” is created and broadcasted via the network N.

  As a result, the route report information issued from the terminal device T12 is received by the route report information receiving unit 160 of all other terminal devices and delivered to the route history writing unit 170. The route history writing unit 170 in each terminal device determines whether or not the medium identification code “CC001” included in the “received route report information” is registered in the route history storage unit 130. If registered, the location information (character string “Tokyo head office No. 102”) included in the “received route report information” is written as a new route history in the storage column for the medium identification code. If it is not registered, the “received route report information” is discarded.

  In the case of the example shown here, other terminal devices (terminal devices other than T12) in which the medium identification code “CC001” is registered in the route history storage unit 130 at this time are terminal devices installed in the Chiba branch office No. 301 room Since it is only T31, the character string “Tokyo head office No. 102” is written as a new route history only in the storage column for the medium identification code “CC001” in the route history storage unit 130 of the terminal device T31. . In other terminal apparatuses, the “received route report information” is discarded. FIG. 5 is a diagram showing a change state of the route history at this time. In the terminal device T31 installed in the Chiba branch office No. 301 room, the character string “Tokyo head office No. 102 room” is stored in the first line of the storage column for the medium identification code “CC001”. A medium identification code “CC001” is newly registered in the installed terminal device T12.

  Next, when “Ichiro Suzuki” moves to the room 104 in the same Tokyo head office and accesses the information recording medium M1 possessed by the terminal device T14, this time, the code reading unit 110 in the terminal device T14 causes the code reading unit 110 in the terminal device T14. The medium identification code “CC001” is read out and registered in the path history storage unit 130 by the code registration unit 120. This registration indicates that “Ichiro Suzuki” has stopped at the 104th headquarters of the Tokyo head office. At this time, the route report information transmission unit 150 in the terminal device T14 also reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Tokyo head office 104 The route report information including the character string “No. Room” is created and broadcasted via the network N.

  As a result, the route report information issued from the terminal device T14 is received by the route report information receiving unit 160 of all other terminal devices and delivered to the route history writing unit 170. Then, the route history writing unit 170 in each terminal device determines whether or not the medium identification code “CC001” included in the “received route report information” is registered in the route history storage unit 130. If it is registered, the location information (character string “Tokyo head office No. 104”) included in the “received route report information” is stored in the storage column for the medium identification code as a new route history. Is written, and if it is not registered, the “received route report information” is discarded.

  In the case of the example shown here, at this time, the other terminal device in which the medium identification code “CC001” is registered in the route history storage unit 130 is the terminal device installed in the room 301 of Chiba branch office as shown in FIG. Since only T31 and the terminal device T12 installed in the Tokyo head office No. 102 room, the character string “Tokyo head office No. 104 room” relates to the medium identification code “CC001” in the route history storage unit 130 of the terminal equipment T31 and T12. Only the storage field is written as a new route history. In other terminal apparatuses, the “received route report information” is discarded. FIG. 6 is a diagram showing a change state of the route history at this time. In the terminal device T31 installed in the Chiba branch office No. 301 room, the character string “Tokyo head office No. 104 room” is stored in the second row of the storage column for the medium identification code “CC001” and is installed in the Tokyo head office No. 102 room. In the terminal device T12, the character string “Tokyo headquarters room 104” is stored in the first line of the storage column for the medium identification code “CC001”. A medium identification code “CC001” is newly registered.

  Now, in the afternoon, “Ichiro Suzuki” moves to room 203 in the Yokohama branch office and accesses the terminal device T23 from the information recording medium M1 that he possessed. This time, the code reading in the terminal device T23 is performed. The medium identification code “CC001” is read by the unit 110 and registered in the path history storage unit 130 by the code registration unit 120. This registration indicates that “Ichiro Suzuki” has visited the Yokohama Office 203 room. At this time, the route report information transmission unit 150 in the terminal device T23 also reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Yokohama branch office 203 The route report information including the character string “No. Room” is created and broadcasted via the network N.

  As a result, the route report information issued from the terminal device T23 is received by the route report information receiving unit 160 of all other terminal devices and delivered to the route history writing unit 170. Then, the route history writing unit 170 in each terminal device determines whether or not the medium identification code “CC001” included in the “received route report information” is registered in the route history storage unit 130. If it has been registered, the location information (character string “Yokohama branch office No. 203”) included in the “received route report information” is stored in the storage column for the medium identification code as a new route history. Is written, and if it is not registered, the “received route report information” is discarded.

  In the case of the example shown here, at this time, the other terminal device in which the medium identification code “CC001” is registered in the route history storage unit 130 is the terminal device installed in the room 301 of Chiba branch office as shown in FIG. Since T31, the terminal device T12 installed in the Tokyo headquarters room 102, and the terminal device T14 installed in the Tokyo headquarters room 104, the character string “Yokohama branch office 203” stores the route history of these three units. The new path history is written in the storage field for the medium identification code “CC001” in the section 130. In other terminal apparatuses, the “received route report information” is discarded.

  FIG. 7 is a diagram showing a change state of the route history at this time. In each of the terminal devices T31, T12, and T14, a character string “Yokohama branch office No. 203” is added as a new route history to the storage column for the medium identification code “CC001”. In addition, a medium identification code “CC001” is newly registered in the terminal device T23 installed in the Yokohama Branch No. 203 room.

  Further in the evening, when “Ichiro Suzuki” moves to room 402 in the Saitama factory and accesses the information recording medium M1 possessed to the terminal device T42, this time, the code reading unit in the terminal device T42. 110, the medium identification code “CC001” is read and registered in the path history storage unit 130 by the code registration unit 120. This registration indicates that “Ichiro Suzuki” stopped by the Saitama Factory Room 402. At this time, the route report information transmission unit 150 in the terminal device T42 also reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Saitama Factory 402 The route report information including the character string “No. Room” is created and broadcasted via the network N.

  As a result, the route report information issued from the terminal device T42 is received by the route report information receiving unit 160 of all other terminal devices and delivered to the route history writing unit 170. Then, the route history writing unit 170 in each terminal device determines whether or not the medium identification code “CC001” included in the “received route report information” is registered in the route history storage unit 130. If it has been registered, the location information (character string “Saitama Factory Room 402”) included in the “received route report information” is stored in the storage column for the medium identification code as a new route history. Is written, and if it is not registered, the “received route report information” is discarded.

  In the case of the example shown here, at this time, the other terminal device in which the medium identification code “CC001” is registered in the route history storage unit 130 is the terminal device installed in the room 301 of Chiba branch office as shown in FIG. T31, the terminal device T12 installed in the Tokyo headquarters room 102, the terminal device T14 installed in the Tokyo headquarters room 104, and the terminal device T23 installed in the Yokohama branch office room 203, "Saitama Factory Room 402" Will be written as a new route history in the storage column for the medium identification code “CC001” in these four route history storage units 130. In other terminal apparatuses, the “received route report information” is discarded.

  FIG. 8 is a diagram showing a change state of the route history at this time. In each of the terminal devices T31, T12, T14, and T23, a character string “Saitama Factory Room 402” is added as a new route history to the storage column for the medium identification code “CC001”. In addition, a medium identification code “CC001” is newly registered in the terminal device T42 installed in the Saitama Factory Room 402.

  Thereafter, “Ichiro Suzuki” returns to his / her seat in the room 301 of the Chiba branch and accesses the information recording medium M1 held by the terminal device T31. Next, the code reading unit 110 in the terminal device T31 causes the medium to be read. The identification code “CC001” is read out and registered in the route history storage unit 130 by the code registration unit 120. However, as shown in FIG. 8, at this point, the medium identification code “CC001” has already been registered in the terminal device T31. As described above, when the code registration unit 120 performs the process of registering the predetermined medium identification code in the route history storage unit 130, if the predetermined medium identification code has already been registered, Two methods can be taken.

  The first method is a method of maintaining the registration state as it is. In other words, no change is made to the contents of the route history storage unit 130, and the state in the terminal device T31 shown in FIG. 8 is maintained as it is. That is, the route history of “Tokyo head office, room 102 → Tokyo head office, room 104 → Yokohama branch office, room 203 → Saitama factory, room 402” remains intact.

  The second method is a method of performing a process of deleting all the path histories in the storage column relating to the registered medium identification code. This is because “Ichiro Suzuki” has returned to the Chiba branch office 301 room, where he has stopped in the past, and as far as the terminal device T31 installed in the Chiba branch office room 301, the route history of “Ichiro Suzuki” This is a processing method based on the idea that it should be reset. When such a processing method is adopted, all the path histories in the storage column relating to the medium identification code “CC001” in the terminal device T31 are deleted, and the state shown in FIG. 4 is restored.

  On the other hand, at this time, the route report information transmitting unit 150 in the terminal device T31 reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Chiba branch office 301 The route report information including the character string “No. Room” is created and broadcasted via the network N.

  As a result, the route report information issued from the terminal device T31 is received by the route report information receiving unit 160 of all other terminal devices and delivered to the route history writing unit 170. Then, the route history writing unit 170 in each terminal device determines whether or not the medium identification code “CC001” included in the “received route report information” is registered in the route history storage unit 130. If registered, the location information (character string “Chiba branch office 301”) included in the “received route report information” is stored in the storage field for the medium identification code as a new route history. Is written, and if it is not registered, the “received route report information” is discarded.

  In the case of the example shown here, at this time point, other terminal devices whose medium identification code “CC001” is registered in the path history storage unit 130 are the terminal devices T12, T14, T23, and T42 as shown in FIG. Since there are four units, the character string “Chiba Branch Office 301” is written as a new route history in the storage column for the medium identification code “CC001” in the four route history storage units 130. In other terminal apparatuses, the “received route report information” is discarded.

  FIG. 9 is a diagram showing a change state of the route history at this time. In each of the terminal devices T12, T14, T23, and T42, a character string “Chiba branch office 301” is added as a new route history to the storage column for the medium identification code “CC001”. In the example shown in FIG. 9, for the terminal device T31 installed in the Chiba branch office No. 301 room, the above-mentioned second method is adopted, the storage column for the medium identification code “CC001” is reset, and the route history is displayed. Although the process of deleting all is performed, when the above-described first method is adopted, the content of the terminal device T31 is maintained in the state shown in FIG.

  Here, consider the case where “Ichiro Suzuki” revisits the Yokohama Branch Office 203 after this. In the Yokohama branch office 203, when the information recording medium M1 possessed by “Ichiro Suzuki” is accessed to the terminal device T23, the code reading unit 110 in the terminal device T23 reads the medium identification code “CC001”, The code registration unit 120 registers the route history storage unit 130. At this time, the route report information transmission unit 150 in the terminal device T23 also reads the read medium identification code “CC001” and the location information stored in the location information storage unit 140 (in this case, “Yokohama branch office 203 The route report information including the character string “No. Room” is created and broadcasted via the network N.

  As a result, the route report information issued from the terminal device T23 is received by the route report information receiving unit 160 of all other terminal devices and delivered to the route history writing unit 170. Then, the route history writing unit 170 in each terminal device determines whether or not the medium identification code “CC001” included in the “received route report information” is registered in the route history storage unit 130. If it has been registered, the location information (character string “Yokohama branch office No. 203”) included in the “received route report information” is stored in the storage column for the medium identification code as a new route history. Is written, and if it is not registered, the “received route report information” is discarded.

  In the case of the example shown here, at this time, the other terminal devices whose medium identification code “CC001” is registered in the route history storage unit 130 are the terminal devices T31, T12, T14, and T42 as shown in FIG. Since there are four, the character string “Yokohama Branch 203 Room” is written as a new route history in the storage column for the medium identification code “CC001” in the route history storage unit 130 of these four units. In other terminal apparatuses, the “received route report information” is discarded.

  FIG. 10 is a diagram showing a change state of the route history at this time. In each of the terminal devices T31, T12, T14, and T42, a character string “Yokohama branch office 203” is added as a new route history to the storage column for the medium identification code “CC001”. In the example shown in FIG. 10 as well, for the terminal device T23 installed in the Yokohama Branch No. 203 room, the above-mentioned second method is adopted to reset the storage column relating to the medium identification code “CC001”, and the route history However, when the above-described first method is adopted, the content of the terminal device T23 is maintained in the state shown in FIG.

  As described above, with reference to FIGS. 3 to 11, the transition of the route history in each terminal device has been described along with the movement of “Ichiro Suzuki”. However, in any terminal device, the medium identification code “ In the storage column relating to “CC001”, a path history indicating a subsequent footprint of “Ichiro Suzuki” who stopped by in the past is accumulated. Of course, in the terminal device visited by another member “Jiro Tanaka”, a storage field relating to the medium identification code “CC002” is created, and a path history indicating the subsequent footprint of this “Jiro Tanaka” is accumulated. Become. In this way, in each terminal device, a route history indicating a subsequent footprint of a specific member who has visited in the past is accumulated separately for each individual member.

  Therefore, the route history presenting unit 180 in each terminal device may include a part of the route history stored in the route history storage unit 130 as necessary (for example, when a presentation instruction is given from the outside). Or you can present everything. In addition, the route history stored in the route history storage unit 130 is updated in real time (although some time lag occurs until the route report information is transmitted from the terminal device at the next moving location). Therefore, it is possible to present the route history that changes every moment.

  For example, FIG. 11 (a) shows that when Ichiro Suzuki moved from the Chiba branch office 301 room to the Tokyo head office 102 room → 104 room → Yokohama branch office 203 room → Saitama factory room 402, Chiba branch office 301 A presentation example is shown when a colleague in the room number gives a presentation instruction to the terminal device T31. Such a display can be performed based on the route history in the terminal device T31 shown in the upper left of FIG. That is, in the illustrated example, the route history is sequentially stored in the terminal device T31 in the form of character strings of the Tokyo head office 102 room, the Tokyo head office 104 room, the Yokohama branch office 203 room, and the Saitama factory room 402. If these character strings are displayed in that order on the display screen, a presentation as shown in FIG. 11A is obtained. A viewer who sees such a presentation (a colleague of “Ichiro Suzuki”) can grasp the footprint of “Ichiro Suzuki” at a glance.

  Thus, in order to present the footprints of a specific member in order, when the path history writing unit 170 writes a new path history in the storage field related to the predetermined medium identification code, the path is written at the end of the storage field. The route history may be additionally written so that a plurality of route histories are sequentially accumulated and stored in the same storage column (as shown in the examples of FIGS. 3 to 10). By doing so, the route history presenting unit 180 simply displays the route history stored in the corresponding storage column for each medium identification code in the order of storage, and the presentation as shown in FIG. . Of course, it is also possible to present in the reverse order of the storage order. In that case, the last moving location is presented first (the display order is upside down from FIG. 11A).

  However, in practice, it is not always necessary to present a list of footprints as shown in FIG. For example, if it is sufficient if only the information “where are you now” can be grasped, only the latest route history at the present time may be displayed as shown in FIG. This display is only for the character string “Saitama Factory No. 402” stored in the bottom row of the terminal device T31 shown in the upper left of FIG. 8 (only one at the end of the route history stored in the storage column). ) Can be extracted.

  Of course, the route history presentation unit 180 can also display, for each individual medium identification code, from the end of the route history stored in the corresponding storage column to a predetermined number in the order of storage or vice versa. is there. For example, if the third to last are displayed, instead of the display shown in FIG. 11 (a), only the three most recent locations of Tokyo head office, room 104 → Yokohama branch office, room 203 → Saitama factory, room 402 are displayed. Is displayed.

  FIGS. 11A and 11B show an example in which only the route history of “Ichiro Suzuki” (route history related to the medium identification code “CC001”) is presented. The terminal devices on which a plurality of members have stopped accumulate route histories for the plurality of members, respectively. In this way, when route histories for a plurality of members are accumulated, the route history may be presented for each member.

  FIG. 12A shows an example in which route histories for three members “Ichiro Suzuki”, “Saburo Sato”, and “Goro Takahashi” are displayed. In this display, “CC001”, “CC003”, and “CC005” are medium identification codes recorded on the information recording media M1, M3, and M5 assigned to these three members, and the path history for each member. As a headline. However, such a medium identification code theoretically functions as a code indicating a specific member, but from the standpoint of a viewer, it is only a code that is difficult to associate with a specific member. Therefore, in practice, a medium identification code including a name character string indicating the name of the owner is recorded on each information recording medium, and the path history presentation unit 180 uses the name character string as a heading. The stored route history may be displayed for each medium identification code.

  For example, in the case of the example shown in FIG. 1, medium identification codes composed of codes “CC001” to “CC005” are recorded on the information recording media M1 to M5, respectively. If a medium identification code consisting of the name character string “Takahashi Goro” is recorded, it is possible to display a route history using a heading consisting of the name character string. However, if a medium identification code consisting only of a name character string is used, confusion occurs when there is a member with the same surname and the same name. In order to avoid such confusion, “CC001: Ichiro Suzuki” to “ A medium identification code composed of a combination of a unique code code and a name character string, such as “CC005: Goro Takahashi”, may be used.

  FIG. 12B is a display example of the route history when the medium identification code composed of such a combination is used. Since the display including the name character string such as “CC001: Ichiro Suzuki” is performed as the headline of the route history of each member, the viewer can easily grasp who the destination is displayed. it can. Further, even if there are members having the same surname and the same name, it is possible to distinguish them by the code code portion.

  In the example shown in FIG. 12B, time information is displayed in parentheses beside each piece of location information. These times indicate the approximate time at which each member arrived at the location. For example, the display “Tokyo head office 102 room (10:30)” indicates that “Ichiro Suzuki” has arrived at the Tokyo head office room 102 at approximately 10:30.

  When such a time display is also performed, when the route history writing unit 170 writes a new route history (location information) in the route history storage unit 130, the writing time is shown together with the route history. Information should be written together. For example, when the location information “Tokyo head office No. 102” is written as a new route history, the time (for example, 10:30) at the time of the writing is added. Then, the route history presentation unit 180 can present information indicating the writing time together with the route history, and the route history with time can be presented as shown in FIG. Become.

  Of course, when the location information is written, it is not the exact time when the member arrives at the location. For example, after “Ichiro Suzuki” arrives at the Tokyo headquarters room 102, until the route history relating to this is recorded in the terminal device T31 of the Chiba branch office room 301, “Ichiro Suzuki” After the terminal device T12 reads the medium identification code of the information recording medium M1, the route report information needs to be transmitted from the terminal devices T12 to T31. Therefore, when the location information “Tokyo head office No. 102 room” is written in the terminal device T31, there is a slight time lag with respect to the arrival time of “Ichiro Suzuki” at the Tokyo head office No. 102 room. However, the presence of such a slight time lag does not cause any practical problem.

  In order to further reduce the time lag, when the route history writing unit 170 writes a new route history (location information) in the route history storage unit 130, together with the route history, “the route from which the route history is based” Information indicating “when report information is transmitted” may be written together. For example, in the above-described example, when the terminal device T12 performs a process of including the transmission time in the route report information when the route report information is broadcasted, the route history writing unit on the terminal device T31 side that has received the processing is included. When 170 writes the route history in the route history storage unit 130, the transmission time can be written together.

  Note that the route history presentation unit 180 of each terminal device can present the route history in a form corresponding to the instruction when a presentation instruction is given from the outside. It is also possible to present a route history when the condition is satisfied. For example, when the condition setting “always present” is set, the route history is always presented. Alternatively, it is possible to set conditions such as “always present the route history for the specific member after 5 minutes have passed since the medium identification code for the specific member has been registered”.

  In practice, it is preferable to present the route history in the form of text display on the display screen, but the route history presentation by the route history presentation unit 180 is not necessarily performed in a visually comprehensible manner. For example, it is possible to present a route history by voice. Specifically, if a telephone automatic response device is used as the route history presentation unit 180, a system that answers a destination by voice in response to a telephone inquiry can be realized.

So far, the basic embodiment of the destination presentation system according to the present invention has been described, but here, several different embodiments are mentioned as more practical examples and modifications.

(1) Practical Configuration Example of Terminal Device As shown in FIG. 1, in the destination presentation system according to the present invention, a plurality of terminal devices connected to each other via a network are essential components. The internal configuration of this terminal device is as disclosed as the terminal device T in FIG. 2, and can actually be realized by a computer incorporating a dedicated program. Of course, this terminal device T can be prepared as a dedicated device for the destination presentation system according to the present invention. However, in practice, the terminal device T has a function as a terminal device for the destination presentation system according to the present invention. If an electronic device having another specific function is used as a terminal device and a medium used for authentication for using this specific function is used as the information recording medium M, the introduction cost of the present invention can be reduced. .

  For example, a general company already has an environment in which various electronic devices such as personal computers are connected via a network. Therefore, if this existing electronic device such as a personal computer is also used as a terminal device according to the present invention as it is, it is not necessary to install new hardware, and the present invention can be introduced at low cost. For example, if a personal computer connected to each other via a network (not limited to an in-house LAN or the Internet) is installed in each room, the personal computer can be installed by incorporating a predetermined dedicated program into the existing personal computer. The function as the terminal device T shown in FIG. 2 can be provided. That is, the individual components constituting the terminal device T described as individual blocks in FIG. 2 are realized by a combination of hardware and software for a personal computer. Of course, each personal computer is an electronic device having a specific function different from the function as the terminal device T for the destination presentation system according to the present invention. There will be no hindrance.

  Recently, a system that requires authentication using an information recording medium such as an IC card when using electronic devices such as personal computers (including printers and copiers) has been constructed for security reasons. There are many cases. In such a case, if the medium (IC card or the like) used for authentication for using the electronic device is used as the information recording medium M in the present invention, the introduction cost of the present invention can be further reduced. it can.

  For example, when an IC card is issued to an individual employee as an employee ID card and an individual electronic device such as a personal computer is used, the IC card is connected to the electronic device (wired connection or wireless connection may be used) When a system for authenticating whether or not the usage authority is given has already been constructed, the IC card can be directly used as the information recording medium M in the present invention. Usually, since a unique code for identifying the IC card is written in such an IC card, this unique code can be used as a medium identification code in the present invention.

  As described above, when the destination presentation system according to the present invention is realized using a system that requires authentication using an information recording medium such as an IC card, convenience in use is also improved. In other words, each employee needs to perform an authentication operation using an information recording medium when using an electronic device such as a personal computer at a stop. In this authentication work, the medium identification code in the information recording medium is inevitably read out to the personal computer side. Therefore, the process of reading the medium identification code using the code reading unit 110 in the present invention is eventually performed by the employee. It is automatically executed by performing the authentication work. In other words, for the purpose of operating the destination presentation system according to the present invention, each employee does not need to work to connect an employee ID card to an electronic device such as a personal computer. For the purpose of authentication, the employee ID may be connected to an electronic device such as a personal computer.

  In particular, if an electronic lock provided on a door or gate for entering and exiting a specific room is used as it is as the terminal device T according to the present invention, each employee can use an IC card or the like that functions as an electronic key. The reading process of the medium identification code using the code reading unit 110 is completed only by performing the work of unlocking the electronic lock using the information recording medium.

  Recently, there are an increasing number of cases where electronic locks are provided on doors and gates, and IC cards are used as electronic keys to unlock them. The form is also increasing. If there is an existing electronic lock system that adopts such an operation mode, each electronic lock can be an electronic device that can function as a terminal device in the present invention (of course, inside the electronic lock). It is necessary to incorporate a dedicated program that functions as the terminal device of the present invention).

  Network connection is also possible for office furniture and fixtures that have electronic operating functions (for example, so-called multi-function machines with multiple functions such as printers, facsimiles, and copiers, and office equipment such as electronic lockers and cabinets). Management operations may be adopted. In such a case, these office furniture and equipment can be used as the terminal device according to the present invention. For example, when an IC card distributed as an employee ID card is used by an employee to unlock an electronic lock of an electronic locker, the medium identification code is read from the IC card, and the location information indicating the installation location of the locker Then, the route report information including the read medium identification code is broadcasted via the network. Thereby, the fact that the employee has stopped at the locker room where the locker is installed is notified.

(2) Practical Configuration Example of Information Recording Medium Next, a configuration example of the information recording medium used in the present invention will be described. As described above, the information recording medium used in the present invention is any medium as long as it has a function of recording a unique medium identification code and is portable so that each member can possess it. It doesn't matter.

  However, practically, as described above, when an electronic device system that requires authentication using an IC card in which a medium identification code is recorded in a memory has already been constructed, the IC card is used in the present invention. It is convenient to divert as it is as an information recording medium used in the above. As the IC card, a contact type IC card having contact electrodes may be used, or a non-contact type IC card having a wireless communication function may be used. In the former case, the reader / writer device that communicates with the IC card through the contact electrode can be used as the code reading unit 110 as it is. In the latter case, a reader / writer device that wirelessly communicates with an IC card can be used as the code reading unit 110 as it is.

  Of course, the information recording medium used in the present invention is not necessarily an electronic device such as an IC card. For example, a medium on which a medium identification code is recorded by printing characters or barcodes can be used, and a medium on which a medium identification code is recorded by a magnetic or optical recording method can also be used. In this case, as the code reading unit 110, a device that reads the medium identification code by an optical or magnetic method may be used.

(3) Addition of Conversion Function to Character String In the embodiment shown in FIG. 2, a place character string (for example, “Chiba Branch Office No. 301 room) indicating the name of its own place as the place information stored in the place information storage unit 140. The route report information transmitting unit 150 broadcasts the route report information including the location character string. For this reason, on the terminal device side that has received this route report information, the route history writing unit 170 writes this location character string “Chiba branch office 301 room” as the route history, and the route history presentation unit 180 receives the location character string. The process of presenting as it was was performed.

  However, the “location information” in the present invention is not limited to information that directly indicates the installation location of the terminal device itself (for example, a location character string such as “Chiba Branch No. 301 room”). It may be information indicating indirectly. For example, a terminal identification code unique to each terminal device (symbols such as T11 to T43 attached to each terminal device in FIG. 1, an IP address, or Ethernet (registered trademark)) This terminal identification code can also be used as “location information” when the communication device is assigned a unique MAC address. In this case, a unique terminal identification code indicating itself is stored as location information in the location information storage unit 140, and the route report information transmission unit 150 includes a route report including this terminal identification code as location information. Information is broadcast.

  However, since this terminal identification code does not directly indicate a specific location, the terminal device that has received the route report information sets the “terminal identification code” to “the terminal identification code” until the destination is presented. It is necessary to convert to a “location character string indicating the name of the installation location of the terminal device specified by the code”. In order to perform such conversion, an individual terminal identification code is stored inside or outside the terminal apparatus (may be a place accessible via a network), and the terminal apparatus identified by the terminal identification code is used. A place character string conversion unit 210 that converts a place character string indicating the name of the installation place is provided, and an environment that can perform the conversion of “terminal identification code” → “place character string” is prepared as necessary. Just keep it.

  FIG. 13 is a table showing a configuration example of such a place character string conversion unit 210. In this example, codes such as “T11”, “T12”, and “T13” are used as terminal identification codes, and “Tokyo head office 101 room”, “Tokyo head office 102 room”, and “Tokyo head office” are used for each. A place character string such as “Room 103” is associated. If such a location character string conversion unit 210 is prepared, terminal identification codes such as “T11”, “T12”, and “T13” become location information that indirectly indicates the installation location of each terminal device. Therefore, the same effect can be obtained by transmitting the terminal identification code “T11” instead of broadcasting the location character string “Tokyo head office 101 room”.

  As described above, when the terminal identification code is broadcasted as the location information instead of the location character string, the route history writing unit 170 on the side of the terminal device that receives the terminal identification code stores the terminal identification code in the route history storage unit 130. What is necessary is just to write as a route history. For example, as the route history for the terminal device T31 in the upper right in FIG. 8, terminal identifications such as “T12”, “T14”, “T23”, and “T42” are used instead of the individual location character strings shown in the figure. The code will be written as is. Then, when the route history presentation unit 180 presents the route history, the location character string indicating the name of the installation location of the terminal device using the conversion result by the location character string conversion unit 210 as shown in FIG. If the route history is presented in the form, the destination can be presented in the same manner as in the previous embodiments.

  Of course, the route history writing unit 170 may perform conversion into a place character string at the stage of writing the route history in the route history storage unit 130. For example, when the route history writing unit 170 receives the terminal identification code “T12”, if the location character string conversion unit 210 shown in FIG. 13 performs conversion at that time, “T12” → “Tokyo head office” Since the place character string “Room 102” can be obtained, the place character string may be written in the route history storage unit 130 as it is. In this case, since the form of the route history in the route history storage unit 130 is exactly the same as the embodiment described so far, the route history presentation unit 180 may perform the process of presenting this place character string as it is. .

  The same is true for the name string. In the above-described embodiment, as a method for displaying a name such as “CC001: Ichiro Suzuki” shown in FIG. 12B, the medium identification code itself is a name such as “CC001: Ichiro Suzuki”. However, for example, if a name character string conversion unit 220 as shown in FIG. 14 is prepared, a medium identification code “CC001” is always used as a name character “Ichiro Suzuki”. It becomes possible to convert to a column.

  That is, each medium identification code is shown inside or outside the terminal device (may be accessible via a network), and the name of the owner of the information recording medium specified by the medium identification code If the name character string conversion unit 220 for converting to a name character string is provided, the route history presentation unit 180 uses the conversion result by the name character string conversion unit 220 and uses the name character string as a headline, The stored route history can be displayed for each medium identification code.

(4) Path History Writing Form In the above-described embodiment, when the path history writing unit 170 writes a new path history in the storage field related to the predetermined medium identification code, the path history is written at the end of the storage field. In the above example, a plurality of route histories are sequentially accumulated and stored in the same storage column. However, when such additional writing is performed, the capacity of the path history storage column increases as the number of stops increases. Of course, if it is preferable to accumulate and present all information related to a specific member's stopovers, it would be necessary to use the additional writing method as in the previous embodiment. When it is sufficient to present only the destination, when the path history writing unit 170 additionally writes the path history at the end of the predetermined storage field, the number of path histories stored in the storage field is predetermined. You may perform the process which deletes an old route log | history sequentially so that it may become below a setting value.

  For example, when setting value = 3, the route history storage unit 130 stores only three route histories, “last stop”, “previous stop”, and “further stop”. Therefore, the route history related to the stop before that is sequentially deleted. Thereby, the recording capacity of the path history storage unit 130 can be saved.

  Further, for example, as shown in FIG. 11 (b), when it is sufficient to present only the “last stop”, the route history storage unit 130 should always store only the latest route history. Good. In this case, the route history writing unit 170 rewrites the old route history stored in the storage column with the new route history when writing the new route history in the storage column related to the predetermined medium identification code. Only the latest route history may be stored in the storage column.

(5) Route History Deletion Unit The route history deletion unit 190 is provided in the terminal device T shown in FIG. The route history deletion unit 190 deletes part or all of the stored contents of the route history storage unit 130 when a deletion instruction is given from the outside or when a predetermined deletion condition set in advance is satisfied. It has a function to perform processing. Although the route history deletion unit 190 is not always necessary in the operation principle of the present invention, in practice, the route history in the route history storage unit 130 cannot be added forever. It is preferable to provide a deletion unit 190 so that a specific route history can be deleted as necessary.

  For example, if this destination presentation system is used in an operation mode in which it is reset in units of one day, a deletion such as “delete all information in the route history storage unit 130 every day at 24:00” Set the conditions. Then, the system will be reset every morning when you go to work (it will return to the initial state of FIG. 3 every morning). Of course, if there is a desire to track the destination for one week, a deletion condition such as “delete all information in the route history storage unit 130 every Sunday” may be set. Is possible. Alternatively, it is possible to set a deletion condition such as “when only 12 hours have elapsed from the time when a specific medium identification code is registered, only the route history related to the specific medium identification code is deleted”.

  Of course, it is also possible to perform an operation of deleting only desired information by giving a specific individual deletion instruction to the route history deletion unit 190 from outside (or via a network).

(6) Electronic Bulletin Board An electronic bulletin board T00 is provided in the system shown in FIG. This electronic bulletin board T00 can be said to be a special terminal device specialized for the destination presentation function. As described above, the general terminal devices T11 to T43 illustrated in FIG. 1 have a first function as a transmission source that broadcasts route report information indicating “who has stopped where” when a specific member stops. And a second function as a presentation device that receives and selects the route report information and presents a destination for a specific member.

  On the other hand, the electronic bulletin board T00 does not have the first function but can be said to be a device specialized for the second function. FIG. 15 is a block diagram showing a basic configuration of the electronic bulletin board T00. As illustrated, the electronic bulletin board T00 includes a code registration unit 120A, a route history storage unit 130A, a route report information receiving unit 160A, a route history writing unit 170A, and a route history presentation unit 180A. These components are almost equivalent to the code registration unit 120, the route history storage unit 130, the route report information receiving unit 160, the route history writing unit 170, and the route history presentation unit 180 in the general terminal device T shown in FIG. Is a component of Moreover, you may add the component equivalent to the path | route history deletion part 190 as needed (it is preferable to add practically).

  However, since this electronic bulletin board T00 is not provided with the code reading unit 110 that reads the medium identification code from the information recording medium M, the code registration unit 120A is based on some instruction input from the outside (for example, the operator A process of inputting a desired medium identification code may be performed), and a process of registering a specific medium identification code as a destination presentation target in the route history storage unit 130A is executed.

  As described above, since the electronic bulletin board T00 does not have the first function as a transmission source for broadcast transmission of route report information, the location information storage unit 140 and the route report information in the terminal device T shown in FIG. A component such as the transmission unit 150 is not necessary.

  In FIG. 1, the installation location of the electronic bulletin board T00 is not specifically shown. Of course, the installation location of the electronic bulletin board T00 may be any location, and a plurality of electronic bulletin boards T00 are installed. It doesn't matter.

(7) Management Device The system shown in FIG. 1 is also provided with a management device T99. The management device T99 can be said to be a special terminal device specialized for collecting route history. FIG. 16 is a block diagram showing a basic configuration of the management apparatus T99. As illustrated, the management device T99 includes a route history storage unit 130B, a route report information receiving unit 160B, and a route history writing unit 170B. Each of these components is almost the same as the route history storage unit 130, the route report information receiving unit 160, and the route history writing unit 170 in the general terminal device T shown in FIG. Moreover, you may add the component equivalent to the path | route history deletion part 190 as needed (it is preferable to add practically).

  The management device T99 is characterized in that it stores and accumulates all the route report information broadcast from the general terminal devices T11 to T43 without selecting them. That is, the route history writing unit 170 of the general terminal device T, when the medium identification code included in the “received route report information” is registered in the route history storage unit 130, The location information included in the “received route report information” is written as a new route history in the storage column related to the code. The route history writing unit 170B of the management device T99 performs such determination processing. Without performing the process, the location information included in all “received route report information” is written as a new route history in the storage field for the corresponding medium identification code.

  More specifically, the route history writing unit 170B adds “received route report information” at the end of the storage column for the medium identification code included in the “received route report information” in the route history storage unit 130B. Is additionally written as a new route history, and a plurality of route histories are sequentially accumulated and stored in the same storage column.

  If such a management apparatus T99 is provided, the destination information regarding all members is accumulated here, so that the storage in the path history storage unit 130B in the management apparatus T99 is stored whenever necessary. By referring to the information, the gait of a specific member can be grasped. For example, if an employee ID card is stolen and the criminal uses a number of electronic devices illegally using the employee ID card, the stored information in the route history storage unit 130B can be referred to. It is possible to grasp the steps of the criminal and to help understand what kind of damage has occurred.
