  FIG. 8 is a flowchart showing operations of the main body control unit 10 and the tag control unit 37. 8A shows the operation of the main body control unit 10, and FIG. 8B shows the operation of the tag control unit 37. FIG. 9 is a waveform diagram showing an envelope of the waveform of the radio signal output from the apparatus main body 2 and the IC tag 5. 9A shows the envelope of the waveform of the radio signal output from the apparatus main body 2, FIG. 9B shows the envelope of the waveform of the radio signal output from the IC tag 5, and FIG. (C) shows the envelope of the waveform of the radio signal output from the other IC tag 5. In FIG. 9, the horizontal axis indicates time, and the vertical axis indicates amplitude. FIG. 9B and FIG. 9C show representative ones of the radio signals output from each IC tag 5. In the present embodiment, a case will be described where the full duplex method is used as the main body control unit 10, the tag control unit 37, and the information transfer method. However, it is not limited to the full duplex method, and may be, for example, a half duplex method or a sequential method. The same applies to other embodiments. Below, operation | movement of the main body control part 10 and the tag control part 37 is demonstrated.

  First, the operation of the main body control unit 10 will be described. When the magnetic card 11 is passed through the reader 6, the storage position detection process is started, and the process proceeds to step a1. In step a1, the identification information is read from the magnetic card 11 passed through the reader 6. The read identification information is stored in the main body storage unit 9. When the identification information is stored, the process proceeds to step a2. Step a2 sets the antenna number N to N = 1. When the antenna number N is set, the process proceeds to step a3. In step a3, the power supply radio signal W1 shown in FIG. 9A is output from the pair of main antenna units 14 to which the set antenna number N is attached. When the power supply radio signal W1 is output, the process proceeds to step a4. In step a4, the request radio signal W3 shown in FIG. 9A is output from the pair of main antenna units 14 to which the antenna number N is attached. When the request radio signal W3 is output, the process proceeds to step a5.

  In step a5, it is determined whether tag wireless signals W4 and W5 output from the IC tag 5 have been received. If it is determined that the tag wireless signals W4 and W5 have not been received, the process proceeds to step a6. In step a6, 1 is added to the antenna number N, that is, N = N + 1 is calculated. When the calculation is performed, the process proceeds to step a7. In step a7, it is determined whether or not the antenna number N is greater than the total number N0 of the pair of main antenna units 14. If N ≦ N0, the process returns to step a3. When N> N0, the process is terminated without causing the display unit 8 to emit light. That is, it is notified that the medical record file 4 (hereinafter simply referred to as “matching file 4”) in which the IC tag 5 having the tag identification information that matches the identification identification information is not stored, and the process ends.

  If it is determined in step a5 that one of the tag wireless signals W4 and W5, for example, the tag wireless signal W4 has been received, tag identification information encoded in the tag wireless signal W4 is detected. Tag identification information to be detected is stored in the main body storage unit 9. When the tag identification information is stored, the process proceeds to step a8. In step a8, it is determined whether or not the tag identification information stored in the main body storage unit 9 matches the identification information. If it is determined that they do not match, the process proceeds to step a6. When it is determined that they match, the display unit 8 associated with the antenna number N is caused to emit light, and the position of the chart storage area 18 in which the match file 4 is stored is notified. When notified, the process is terminated.

  Next, the operation of the tag control unit 37 will be described. When the power supply radio signal W1 is received by the tag antenna 31, the IC tag driving process is started, and the process proceeds to step b1. In step b1, the tag antenna 31 generates an induced electromotive force by the received power supply radio signal W1. As a result, electric power is supplied to the tag control unit 37 and a standby state is established. Charging capacitor 35 starts charging. When in the standby state, the process proceeds to step b2. In step b2, it is determined whether or not the request wireless signal W3 has been received. If it is determined that the requested wireless signal W3 has not been received, the process returns to step b1 and enters a standby state. If it is determined that the requested wireless signal W3 has been received, the requested signal is detected based on the requested wireless signal W3. When the request signal is detected, the process proceeds to step b3. In step b3, tag identification information is read from the tag storage unit 36. When the tag identification information is read, the process proceeds to step b4. In step b4, tag wireless signals W4 and W5 (FIG. 9B and FIG. 9C) based on the read tag identification information are output from each tag antenna 31. When the tag wireless signals W4 and W5 are output, the process ends.

  Below, the effect which the accommodation position detection apparatus 1 of the medical chart comprised in this way show | plays is demonstrated. According to the medical chart storage position detection device 1 of the present embodiment, the main body control unit 10 excites the main body antenna 17 to generate an alternating magnetic field in the medical chart storage area 18. In the chart storage area 18 where an alternating magnetic field is generated, the IC tag 5 generates an induced electromotive force by the tag antenna 31. The tag control unit 37 is driven by the induced electromotive force, reads the tag identification information stored in the tag storage unit 36, and outputs the tag identification information by the tag antenna 31. This tag identification information is detected by the main body control unit 10, and it is determined whether or not it matches the identification information read from the magnetic card 11. When the tag identification information matches the identification information, the main body control unit 10 notifies the display unit 8 that the matching file 4 is stored in the chart storage area 18. Thus, when tag identification information is allocated in advance and stored in each tag storage unit 36, it is determined whether or not the coincidence file 4 is stored in the chart storage area 18 simply by reading the identification information from the magnetic card 11. I can know. Therefore, the burden of search work for searching for the coincidence file 4 can be reduced. In other words, labor costs associated with the search work can be reduced. Further, it is possible to omit the confirmation work for checking the tag identification information stored in the IC tag 5 provided in the medical record file 4 one by one, and the labor cost associated with the confirmation work can be reduced.

  According to the chart storage position detection apparatus 1 of the present embodiment, the pair of main body antenna units 14 are provided in the plurality of chart storage areas 18, respectively. The main body control unit 10 sequentially excites a pair of main body antennas 17 to generate an alternating magnetic field in the chart storage area 18. By sequentially exciting, it is possible to determine whether or not the coincidence file 4 is stored for each chart storage area 18. Thereby, it is possible to know in which chart storage area 18 the matching file 4 is stored, that is, the storage position where the matching file 4 is stored. Therefore, even if a plurality of chart storage areas 18 are formed, if different tag identification information is allocated to each IC tag 5 and stored in the tag storage means in advance, the identification information is read from the magnetic card 11. It is possible to know the storage position where the matching file 4 is stored. Therefore, the burden of search work for searching for the coincidence file 4 can be reduced. In other words, labor costs associated with the search work can be reduced.

  According to the chart storage position detection device 1 of the present embodiment, when the identification information matches the tag identification information, the main body control unit 10 finds that the matching file 4 is in the chart storage area 18 in which the matching file 4 is stored. It is informed by the display unit 8 corresponding to the medical chart storage area 18 that it is stored. Thus, the chart storage area 18 in which the matching file 4 is stored can be easily known. Therefore, it is possible to reduce the burden of search work for searching for the matching file 4. In other words, labor costs associated with the search work can be reduced.

  According to the chart storing position detecting device 1 of the present embodiment, the ferrite plate 15 is interposed between the two main body antenna units 14 in the main body antenna unit 3. Thus, the pair of main antenna units 14 can generate an alternating magnetic field having strong directivity in one direction, specifically, in a direction in which they are close to each other. As a result, the pair of main antenna units 14 can generate an alternating magnetic field only in the chart storage area 18 formed by them, and can output a radio signal. Therefore, it is possible to realize whether or not the chart file 4 is stored for each chart storage area 18. Thus, when the display unit 8 emits light, the medical record file 4 can be surely found by searching the chart storage area 18 corresponding to the display unit 8 that emits light.

  According to the chart storage position detection apparatus 1 of the present embodiment, the pair of main body antenna units 14 searches for the matching file 4 from among the plurality of chart files 4 stored in the chart storage area 18. Therefore, the number of parts can be reduced as compared with the case where the main body antenna 17 is provided for each chart file 4. Therefore, the structure can be simplified and the manufacturing cost can be reduced.

In step c3, the power supply radio signal W1 shown in FIG. 11A is output from the pair of main antenna units 14 to which the set antenna number N is attached. When the power supply radio signal W1 is output, the process proceeds to step c4. In step c4, the identification radio signal W6 shown in FIG. 11A is output from the pair of main antenna units 14 to which the antenna number N is attached. When the identification wireless signal W6 is output, the process proceeds to step c5.

  In step c5, it is determined whether or not the response wireless signal W7 output from the IC tag 5A has been received. If it is determined that the response wireless signal W7 has not been received, the process proceeds to step c6. In step c6, 1 is added to the antenna number N, that is, N = N + 1 is calculated. When the calculation is performed, the process proceeds to step c7. In step c7, it is determined whether or not the antenna number N is larger than the total number N0 of the pair of main antenna units 14. If N ≦ N0, the process returns to step c3. In the case of N> N0, the display unit 8 does not emit light and the process is terminated. That is, it is notified that the coincident chart file 4 is not stored, and the process is terminated.

  If it is determined in step c5 that the response wireless signal W7 has been received, a response signal encoded in the response wireless signal W7 is detected. When the response signal is detected, the process proceeds to step c8.

  Below, the effect which 1A of medical chart accommodation position detection apparatuses comprised in this way show is demonstrated. According to the chart storage position detection apparatus 1A of the present embodiment, the main body control unit 10A excites the main body antenna unit 14 to generate an alternating magnetic field in the chart storage area 18. This alternating magnetic field is encoded based on the identification information read from the magnetic card 11 by the main body control unit 10A. In the chart storage area 18 where an alternating magnetic field is generated, the IC tag 5A generates an induced electromotive force by the tag antenna 31. The tag controller 37A is driven by this induced electromotive force. The tag control unit 37A detects identification information to be encoded.

When receiving the response wireless signal W7, the main body control unit 10A notifies the display unit 8 that the matching file 4 is stored in the medical chart storage area 18 by emitting light. Accordingly, when different tag identification information is allocated to each IC tag 5A in advance and stored in the tag storage unit 36, the matching file 4 is stored in the chart storage area 18 simply by reading the identification information from the magnetic card 11. You can know if you are. Therefore, the burden of search work for searching for the coincidence file 4 can be reduced. In other words, labor costs associated with the search work can be reduced. Moreover, the confirmation work which confirms the tag identification information memorize | stored in IC tag 5A provided in the medical chart container 4 can be omitted, and the labor cost accompanying a confirmation work can be reduced.

  According to the chart storage position detection apparatus 1A of the present embodiment, the same effects as the chart storage position detection apparatus 1 of the first embodiment can be obtained.

  FIG. 12 is a block diagram showing an electrical configuration of an IC tag 5B included in the chart storage position detection device 1B according to the third embodiment of the present invention. FIG. 13 is a flowchart showing operations of the main body control unit 10B and the tag control unit 37B. FIG. 13A shows the operation of the main body control unit 10B, and FIG. 13B shows the operation of the tag control unit 37B. The chart storage position detection device 1B of the third embodiment is similar to the chart storage position detection apparatus 1B of the second embodiment. Therefore, only the difference between the chart storage position detection device 1B and the chart storage position detection apparatus 1B according to the second embodiment will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted. To do. Hereinafter, the storage position detecting apparatus 1B for medical charts will be described with reference to FIGS. 1 to 7, FIG. 10, and FIG.

  The tag display part 42 is, for example, an LED, and is disposed on the other surface part 30 in the thickness direction of the first or second cover part 19, 20 of each chart file 4, or the inner folding part 21. The tag display unit 42 has a function of emitting light and informing the user, for example. The tag display unit 42 is electrically connected to the tag control unit 37B. When the identification information matches the tag identification information, the tag control unit 37B supplies an induced electromotive force to the tag display unit 42 to drive the tag display unit 42.

The operation of the main body control unit 10B differs from the operation of the main body control unit 10B of the second embodiment only in step c5. Therefore, with respect to the operation of the main body control unit 10B, “c” in each step in the flowchart is replaced with “e”, and only step e5 will be described, and description of other steps will be omitted. In step e5, it is determined whether or not the response wireless signal W7 output from the IC tag 5B has been received. If it is determined that the response wireless signal W7 has not been received, the process proceeds to step e6.

When in the standby state, the process proceeds to step f2. In step f2, it is determined whether or not the identification wireless signal W6 has been received. If it is determined that the identification wireless signal W6 has not been received, the process returns to step f1. If it is determined that the identification wireless signal W6 has been received, identification information is detected based on the identification wireless signal W6, and the identification information is stored in the tag storage unit. When the identification information is stored, the process proceeds to step f3. In step f3, the tag identification information is read from the tag storage unit 36, and it is determined whether or not it matches the identification information. If it is determined that they do not match, the process ends. If it is determined that they match, the process proceeds to step f4. In step f4, power is supplied to the tag display unit 42 to emit light, and the user is notified of the position of the coincidence file 4. When notified, the process proceeds to step f5. In step f5, the response wireless signal W7 (FIG. 11B) is output by the tag antenna 31. When the response wireless signal W7 is output, the process ends.

As a result, the matching file 4 can be easily found from the plurality of chart files 4, and there is no need to search the plurality of chart files 4. Therefore, it is possible to further reduce labor costs associated with the search work.

  In the present embodiment, the storage position of the chart file 4 is notified by the display unit 8 emitting light, but the present invention is not necessarily limited thereto. For example, the location may be notified by sound. For example, the storage position may be notified by voice guidance. As a result, the same effects as those of the medical chart storage position detection devices 1 and 1A according to the first and second embodiments are obtained.

  In the present embodiment, all the IC tags 5, 5A, 5B output radio signals having the same frequency, but may be IC tags 5, 5A, 5B that output radio signals having different frequencies. . In this case, for example, the apparatus main bodies 2, 2 </ b> A, 2 </ b> B are provided with the main body antenna device 14 for each frequency of the radio signal to be received. Accordingly, the apparatus main bodies 2, 2A, 2B can receive the radio signals output from the IC tags 5, 5A, 5B without interference. As a result, the transmission of radio signals between the IC tags 5, 5A, 5B and the apparatus main bodies 2, 2A, 2B can be realized with certainty.

  In the present embodiment, the medical record file 4 is described, but the present invention is not necessarily limited to this.

In this case, the individual information associated with the identification information is stored in the magnetic card 11. Individual information is read from the magnetic card 11 by the reader 6. The main body control units 10, 10A, 10B read the identification information associated with the individual information from the storage unit. Even with such a configuration, the same effects as the chart storage position detection devices 1, 1A, 1B of the present embodiment can be obtained.
