Further, in order to manage the movement of the information storage medium, a time-out value TL is set in advance, and if the information identifier is not received during that time, it is determined that the storage location has moved to another location. , Remove from list. That is, as shown in FIG. 8, the time stamp value of the information identifier received first among the information identifiers of the internal data is set in the variable OT (step S81), and the time stamp value OT is set from the current time CT. It is determined whether or not the subtracted value exceeds the timeout value TL, that is, whether CT-OT ≧ TL is true or false (step S82). As a result of the determination, when the time-out value is exceeded, the information identifier having the time stamp value OT is deleted from the internal data (step S8).
3) The information identifier having the oldest time stamp value for the internal data is searched (step S84), the time stamp value of the searched information identifier is set in the variable OT (step S85), and the process goes to step S82. If the result of determination in step S82 is that the oldest time stamp value set in the variable OT has not exceeded the timeout value, the internal data is searched for an information identifier having the oldest time stamp value (step S84). The time stamp value of the retrieved information identifier is set in the variable OT (step S85), and the process proceeds to step S82. This time-out value is set, for example, by the transmitter of the information storage medium shown in FIG.
In the case of a configuration in which transmission is performed at an appropriate time interval as in (a), a value equal to the maximum value of the time interval may be set.

The time-out information may be changed in the configuration so that the communication device at the storage location makes a list and sends it to the management terminal. The communication device at the storage location is

That is, as shown in FIG. 9, the wireless channel is sensed (step S91), and it is checked whether data from the information storage medium is received (step S92). If not received, the process returns to step S91 to wait for the next sense. When the data from the storage medium is received, the timer is started (step S93) and the received identifier is stored in the storage unit 45 (step S94). It is checked whether or not the timer value is equal to or higher than a predetermined upper limit value TO (step S95), and while the timer value is smaller than the upper limit value TO, the process returns to step S94. The timer value is the upper limit value T
When it becomes O or more, the storage location identifier stored in the ROM 44 and the received information identifier stored in the storage unit 45 are read into the transmission unit 41 (step S96). The transmission unit 41 transmits the read storage location identifier and information identifier to the management terminal 15 (step S97). When the transmission is completed, the contents of the storage unit 45 are erased (step S9
8) Reset the timer (step S99) and return to the beginning.

According to the present embodiment, it becomes possible to manage not only the file but also the material therein, so that the efficiency of the material search and the material arrangement can be improved.

In the above embodiment, the number is used as the information identifier, but the OSI directory name may be used. This advantage is that only one naming in the world is possible, and the naming is different from the number and is user-friendly, so that it can be understood even if it is displayed to the user as it is.

(Seventh Embodiment) The seventh embodiment is similar to the first to fifth embodiments in the overall schematic structure, as described with reference to FIG. The difference is the configuration of the transmitter included in the information storage medium. That is, FIG. 20 shows a configuration of a transmitter included in the information storage medium of the present embodiment.
02 and ROM 203 are the same as the other embodiments described above, but this embodiment is different in that a power supply receiving section 204 is provided. The power receiver 204 of this transmitter is supplied from the media storage device at the storage location.

FIG. 21 is a flow chart showing the operation of the transmitter of the information storage medium. By placing the information storage medium in the storage location of the medium storage device, the power supply receiving unit 204 is supplied with current (step S211), and the transmitting unit 201 operates. The transmission unit 201 reads the information identifier stored in the ROM 203 (step S212), and transmits only once under the control of the control unit 202 (step S212).
213).

In order to ensure the transmission, the transmission may be continued twice or more. FIG. 22 shows a flowchart when the number of transmissions is N times. A current is supplied by placing the information storage medium in the storage location (step S221), and the identifier is read from the ROM and transmitted (steps S222 and S223). Then, it is checked whether the data has been transmitted N times (step S224), and if the data has not been transmitted N times, the data is further transmitted. When the transmission is completed N times, the transmission is completed.

Since the configuration and operation of the communication device in the storage location are the same as those in the first embodiment, description thereof will be omitted (see the block diagram of FIG. 4 and the flowchart of FIG. 5). In addition to this, a transmission method using a timer is also possible, in which a transmission interval T _Max is determined and the information identifiers received are collectively sent at that interval. FIG. 23 shows the flow of the process. After the timer is reset, the timer is started (step S231) and the received identifier is stored in the storage unit 45 (step S232). It is checked whether the timer value is equal to or more than the transmission interval T _Max (step S23
3) If the timer value is smaller than the transmission interval T _{Max, the} process returns to step S232. When the timer value reaches the transmission interval T _Max or more, the storage location identifier stored in the ROM 44 and the received information identifier stored in the storage unit 45 are read into the transmission unit 41 (step S234). The transmission unit 41 transmits the read storage location identifier and information identifier to the management terminal 15 (step S235). When the transmission is completed, the contents of the storage unit 45 are erased (step S23
6) Return to the beginning. The value of T _Max is set according to the movement frequency of the information storage medium to be managed. In other words, reduce the value in places where the frequency of movement is high, and
Try to increase the value. In addition, this wireless receiver
By having an antenna with directivity that matches the shape of the storage location, it is possible to receive only the radio waves in the corresponding storage location.

When the management terminal receives the information identifier and the storage location identifier from the storage location as shown in FIG. 24, it checks whether the information identifier is registered in the internal data (steps S241 to S243). If not registered, it is registered (step S245). If they have already been registered, the storage location identifiers are compared (step S244). If they are different, it can be determined that the information storage medium has moved to a new location, so the information is rewritten to a new storage location identifier (step S246).

As described above, even if the information storage medium frequently moves, the management terminal can be automatically notified of the correspondence between the storage location and the information storage medium, so that the information can be quickly managed. . Moreover, since the transmission timing is only when there is a movement, unnecessary transmission is eliminated, and the congestion of the communication path can be reduced. Further, in this embodiment, since the transmitter of the information storage medium does not have a power source, cost reduction can be achieved, and unnecessary power source is not thrown away, which does not adversely affect the environment.

(Embodiment 8) In Embodiment 8, a file is an information storage medium, a shelf is a storage location, and the overall schematic configuration is as shown in FIG. File is Figure 26
As shown in (a), the communication device 26 with the file ID
Has 1. Shelf 25 in the storage place for storing the file
1 to 252 are communication devices 253 with a storage location identifier
254, and these communication devices 253-254 are connected to the management terminal 25 via a wired or wireless communication line 255.
It is connected with 6.

The bottom of each file is shown in FIG.
, There are contact surfaces 263, 264 for receiving power, and positive and negative linear electrodes 265 for supplying power to the file, as shown in FIG. 26C, at the bottom of the shelf.
266 stretches across the shelf. Note that FIG.
(C) is the figure which looked at the shelf from the top. The vertical length (direction along the shape of the file) of the contact surface at the bottom of the file may be any length smaller than the distance between the two linear electrodes 265, 266. Further, the two contact surfaces 263, 264 need to be set not in parallel but in the vertical direction.
As shown in FIG. 26D, the distance between the center lines of both contact surfaces is set to be equal to the distance between the linear electrodes. When the file is placed, the contact surfaces 263, 264 may be slightly deviated from the linear electrodes 265, 266, but this setting is most suitable for this deviation. Furthermore, if the vertical length of the contact surface is as close as possible to the distance between the linear electrodes, the deviation can be better dealt with.

When the files A and B are placed on the shelf 251 and the file C is placed on the shelf 252, the file IDs of these files are transmitted to the communication devices 253 and 254 on the shelf, and the management terminal 256 together with the storage location identifier of the shelf. Sent to. The storage form inside the management terminal 256 at this time is as shown in FIG.
The table is composed of items D, shelf name, and shelf ID. Next, if the file A placed on the shelf 251 is moved to the shelf 252, the data inside the management terminal 256 is updated, and the storage form is as shown in FIG. 27 (b). This allows the management terminal to know the location of a file simply by placing it on a shelf, which makes it possible to improve the efficiency of material search and material organization.
