Description

  The present invention relates to an automatic archive system.

  2. Description of the Related Art Conventionally, a technique for managing books stored in a container using an RFID (Radio Frequency Identifier) technique using radio waves in an UHF (Ultra High Frequency) band is known.

  Here, the book management is an operation of moving a container in which a specific book is accommodated to the operator's work space based on the operator's command.

  Books accommodated in the containers are attached with IC tags storing individual book information. Further, the book information of the IC tag can be read by a receiver using RFID technology. Therefore, the book management is performed by reading and detecting the book information of the IC tag of the book stored in the container by the receiver using the RFID technology.

  Here, the books in the container are put in and out by the operator's work. That is, the books in the container are changed when the operator stores the books in the container and when the operator takes out the books from the container.

  Therefore, when the books in the container are put in and out, the automatic library system reads and stores the IC tags of the books stored in the container. By detecting a book every time a book in the container is changed, the automatic library system can store the latest book stored in the container.

  By storing the latest books stored in the container in advance, when the operator inputs an instruction to take out a specific book, the container in which the specific book is stored can be accurately detected. it can.

  Here, an IC tag receiver using radio waves in the UHF band has a reading distance of about several meters. Therefore, the IC tag receiver may read the book information of the IC tag outside the container. Therefore, the IC tag receiver may not be able to accurately read the book information of the IC tag of the book accommodated in the container.

  Thus, there is a need for an automatic library system that accurately detects books contained in containers.

  So far, for example, there has been disclosed a book management system for reading a book code by a reader / writer from a wireless tag of a book housed in a container (see, for example, Patent Document 1).

  In addition, a book storage management device is disclosed that includes detection means for setting the entire opening for a user to take out a book from a container at a station as a detection range of a detected object that is inserted through the opening (for example, Patent Documents). 2).

  However, Patent Documents 1 and 2 do not consider the case where the IC tag receiver reads the book information of the IC tag outside the container.

The container housing unit 12 includes a container delivery port 111 and a container storage port 112 that communicate with the outside of the depositing station 11 at the rear. A library unit (not shown) is constructed outside the cashier station 11.

  The work container 2 is transported from the container outlet 111 to the inside of the container housing unit 12 by the transport device. In addition, the work container 2 is transported from the container storage port 112 to the outside of the container storage unit 12 by the transport device and stored in the library unit.

  The container housing unit 12 includes a barcode reader 16. The barcode reader 16 reads the barcode 21 of the work container 2 accommodated in the container accommodating portion 12. The barcode reader 16 is disposed in front of the left surface of the work container 2 in FIG. 1 so as to face the barcode 21. The barcode reader 16 reads the barcode 21 to identify the work container 2 accommodated in the container accommodation unit 12.

  The container housing unit 12 includes an internal antenna 121, an internal antenna 122, and an internal antenna 123.

  The internal antennas 121 to 123 are antennas that can read the IC tag of the book 110 accommodated in the work container 2. The internal antennas 121 to 123 are connected to an internal IC reader / writer (not shown).

  The internal antennas 121 to 123 are arranged so as to face the three surfaces of the work container 2. That is, the internal antenna 121 is to the left of the work container 2 when viewed from the operator 50, the internal antenna 122 is above the work container 2 when viewed from the operator 50, and the internal antenna 123 is viewed from the operator 50. Arranged in the upper right of the work container 2.

  Note that there are three internal antennas 121 to 123 in the present embodiment. However, the number of internal antennas may be two or less or four or more. By arranging a plurality of internal antennas 121 to 123, a book accommodated in the work container 2 can be read more accurately.

  Further, the internal antennas 121 to 123 may have a function of writing to the IC tag of the book 110 as necessary. Further, the internal antennas 121 to 123 have a function of detecting signal change information of the book 110 in time series. Here, the signal change information is a change amount of received signal strength (hereinafter also referred to as “RSSI”) from the IC tag, a change amount of the signal phase, or a change amount of the Doppler frequency.

  The signal change information may be calculated based on the RSSI change amount and the signal phase change amount from the IC tag. The signal change information may be calculated based on the RSSI change amount from the IC tag and the Doppler frequency change amount of the signal of the IC tag. Further, the signal change information may be calculated based on the RSSI change amount from the IC tag, the signal phase change amount, and the Doppler frequency change amount.

● Configuration of the gate 13

  The gate unit 13 is a gate capable of depositing and unloading the books 110 between the outside of the depositing / dispensing station 11 and the work container 2. The operator 50 can put in and out the books 110 in the automatic library system 100 through the gate unit 13.

  The gate portion 13 is formed with a communication path 200 that communicates the outside of the depositing / dispensing station 11 with the container housing portion 12. That is, the operator 50 can put in and out the book 110 accommodated in the work container 2 through the communication path 200.

  The gate unit 13 includes a gate antenna 131 and a gate antenna 132.

  The gate antennas 131 and 132 are antennas that can read the IC tag of the book 110 existing in the communication path 200. The gate antennas 131 and 132 are connected to a gate IC reader / writer (not shown).

  The gate antennas 131 and 132 are disposed on the left and right with the communication path 200 interposed therebetween. That is, the gate antenna 131 is disposed on the left side of the operator 50 in the walls constituting the communication path 200, and the gate antenna 132 is disposed on the right side of the operator 50 in the walls configuring the communication path 200.

  Note that there are two gate antennas 131 and 132 in this embodiment. However, the number of gate antennas may be one or three or more. By arranging a plurality of gate antennas 131 and 132, the book 110 existing in the communication path 200 can be read more accurately.

  The gate antennas 131 and 132 may be installed on the left and right of the operator 50 on the table surface 133 of the gate unit 13. By installing the gate antennas 131 and 132 on the left and right of the operator 50 on the table surface 133, the book 110 passing through the communication path 200 can be read accurately.

  The gate antennas 131 and 132 may have a function of writing to the IC tag of the book 110 as necessary.

  The gate antennas 131 and 132 have a function of detecting signal change information of the book 110 in time series.

  The gate antennas 131 and 132 acquire moving book information based on the signal change information. Here, the moving book information is book information held by an IC tag of a book whose signal is changing. The gate antennas 131 and 132 can identify the book 110 that moves within the detection range of the gate antennas 131 and 132 by acquiring the moving book information.

  The moving book information includes book information of books stored in the work container 2 from the outside of the depositing / dispensing station 11 and book information of books taken out of the depositing / receiving station 11 from the work container 2. Here, for convenience of explanation, the book information of the books stored in the work container 2 from the outside of the cashier station 11 is stored, and the book information of the books taken out from the work container 2 to the outside of the cashier station 11 is taken out. This is called library information.

  The length of the communication path 200 is provided to be equal to or longer than a half wavelength of the radio wave for detecting the IC tag. Here, the wavelength λ of the radio wave is expressed by the following formula 1 because the frequency is 920 MHz.

(Formula 1)
λ = v / f
≒ 3 × 10 ⁸ (m / s) / 9.2 × 10 ⁸ (Hz)
= 0.326 (m)
= 326 (mm)

  Therefore, the half wavelength λ / 2 of the radio wave is 163 mm.

  With this configuration, the amount of change in RSSI, the amount of change in signal phase, and the amount of change in Doppler frequency when the book 1101 moves through the communication path 200 increases, so the book moves within the detection range of the gate antennas 131 and 132. 1101 can be specified more accurately.

● Configuration of the first detector 14 and the second detector 15

  The first detector 14 is a sensor that detects whether or not an object is present at the front end of the communication path 200 on the container accommodating portion 12 side. The first detector 14 includes a first detector transmitter 141 and a first detector receiver 142. The first detector transmission unit 141 and the first detector reception unit 142 are provided on both sides of the front opening so as to sandwich the front opening on the container housing unit 12 side of the communication path 200.

  The detection range of the first detector 14 is between the first detector transmitter 141 and the first detector receiver 142. That is, it is a frontage of the communication path 200 on the container accommodating portion 12 side.

  The 1st detector 14 outputs the 1st existence information of an ON state or an OFF state to control part 3 mentioned below. Here, the on state is a state in which an object exists in the detection range of the first detector 14. The off state is a state in which no object exists in the detection range of the first detector 14.

  The second detector 15 is a sensor that detects whether or not an object is present at the front side of the communication path 200 outside the depositing / dispensing station 11. The second detector 15 includes a second detector transmitter 151 and a second detector receiver 152. The 2nd detector transmission part 151 and the 2nd detector receiving part 152 are provided in the both sides of the front opening so that the front side of the communication path 200 outside the depositing station 11 may be pinched | interposed.

  The detection range of the second detector 15 is between the second detector transmitter 151 and the second detector receiver 152. That is, it is a frontage of the communication path 200 on the outside of the depositing / dispensing station 11.

  The 2nd detector 15 outputs the 2nd existence information of an ON state or an OFF state to control part 3 mentioned below. Here, the on state is a state in which an object exists in the detection range of the second detector 15. The off state is a state in which no object exists in the detection range of the second detector 15.

  That is, the first detector 14 and the second detector 15 can detect whether the hand of the operator 50 enters and exits the work container 2 through the communication path 200. That is, when the hand of the operator 50 enters the work container 2, the second detector 15 is turned on, and then the first detector 14 is turned on. Further, when the hand of the operator 50 leaves the work container 2, the first detector 14 is turned off, and then the second detector 15 is turned off.

  The first detector 14 and the second detector 15 are, for example, a light emitting element and a light receiving element.

  As shown in FIG. 2, the automatic archive system 100 includes four types of sensors used in different applications in the automatic archive system 100, that is, a first detector 14, a second detector 15, internal antennas 121 to 123, a gate. Antennas 131 and 132 are provided. The first detector 14 acquires first presence information, the second detector 15 acquires second presence information, the internal antennas 121 to 123 acquire internal book information, and the gate antennas 131 and 132 are mobile book information. And signal change information is acquired.

● Configuration of control unit 3

  The control unit 3 is an information processing apparatus that manages a plurality of books 110 accommodated in the work container 2.

  As shown in FIG. 3, the control unit 3 includes the first presence information acquired by the first detector 14, the second presence information acquired by the second detector 15, the internal book information acquired by the internal antennas 121 to 123, The signal change information and the moving book information acquired by the gate antennas 131 and 132 are received.

  In addition, the control unit 3 acquires the number of books to be stored input from the operation terminal 102 to the operation terminal 102. Further, the control unit 3 transmits information on the book that has been put in and out to the operation terminal 102.

● Configuration of storage unit 4

  The storage unit 4 stores reference book information of the book 110 accommodated in the work container 2. The reference book information includes individual book information groups of a plurality of books 110 accommodated in the work container 2. That is, the reference book information is information before the operator 50 puts the book 110 in and out. The reference book information is updated to the book information group after receipt and receipt after completion of receipt and receipt.

● Configuration of search unit 5

  The search unit 5 acquires reference book information from the storage unit 4, determines whether or not moving book information exists in the reference book information, and transmits the determination result to the control unit 3.

Book Storage Processing The book storage processing shown in FIG. 4 will be described. The book storage process (S100) is a process for detecting that the operator 50 has stored the book 1101 in the work container 2. Here, the book 1101 is an example of a book stored in the work container 2 by the operator 50.

  As shown in FIG. 4, in the book storage process (S100), the control unit 3 first acquires the number of books to be stored input to the operation terminal 102 (S101).

  Next, the operator 50 inserts the book 1101 into the communication path 200 from the outside of the depositing / dispensing station 11 (S102).

  The second detector 15 detects the presence of the hand of the operator 50 inserted into the communication path 200 in step S102 and is turned on (S103).

  The gate antennas 131 and 132 start acquiring signal change information of the IC tag of the book 1101 in the communication path 200 (S104).

  Next, the control unit 3 acquires stored book information of the book 1101 whose signal is changing based on the signal change information (S105).

  Next, the search unit 5 calls the reference book information from the storage unit 4. Further, the search unit 5 searches the stored book information from the reference book information (S106).

  The book 1101 corresponding to the stored book information is a book inserted by the operator 50 from the outside of the depositing / dispensing station 11, and therefore should not be stored in the reference book information. Therefore, when the stored book information is stored in the reference book information, the control unit 3 notifies the abnormality (S108).

  On the other hand, when the stored book information is not stored in the reference book information, the control unit 3 compares the number of input books acquired in step S101 with the number of stored book information acquired by the gate antennas 131 and 132. (S107).

  When the number of input books is different from the number of books in the stored book information, the control unit 3 requests the operator to input again through the operation terminal 102 (S109). Next, the control unit 3 returns to the process of step S101.

  When the number of input books and the number of books in the stored book information are equal, the control unit 3 waits for the operation of the operator 50. When the operator 50 inserts the book 1101 into the work container 2 (S110), the first detector 14 is turned on (S111).

  Next, the control unit proceeds to the process of the extraction process (S200) after storing the books.

● Retrieval Processing after Storage of Books The extraction processing after storage of books shown in FIG. 5 will be described. The extraction process after storing the book (S200) is a process for detecting that the operator 50 has taken out the book 1102 from the work container 2 after storing the book. Here, the book 1102 is an example of a book taken out from the work container 2 by the operator 50.

  The retrieval process after storing the book (S200) is a case where the book is retrieved without a retrieval request command to the operation terminal 102. That is, this is different from the normal book extraction process (S500) described later. Therefore, the control unit 3 may issue a warning to the operation terminal 102 when the extraction process (S200) after storing the book is performed.

  As shown in FIG. 5, first, the operator 50 grasps the book 1102 in the work container 2 and removes it from the container accommodating portion 12 (S201). At this time, the hand of the operator 50 exists in the communication path 200 together with the book 1102.

  The first detector 14 detects that the hand of the operator 50 has left the work container 2 in step S201 and is turned off (S202).

  The gate antennas 131 and 132 start acquiring signal change information of the IC tag of the book 1102 in the communication path 200 (S203).

  Next, the control unit 3 acquires the extracted book information of the book 1102 whose signal is changing based on the signal change information (S204). Here, the control unit 3 waits for an operation of the operator 50.

  When the operator 50 takes the book 1102 out of the banking station 11 (S205), the second detector 15 is turned off (S206).

Next, the control unit 3 confirms the presence / absence of the extracted book information (S207). Here, when there is no extracted book information, the control unit 3 proceeds to a stored book confirmation process (S300).

  When there is the extracted book information, the search unit 5 calls the reference book information corresponding to the work container 2 specified by the barcode reader 16 from the storage unit 4. In addition, the search unit 5 searches the extracted book information from the reference book information (S208).

  Since the book 1102 corresponding to the taken-out book information is a book taken out from the work container 2 by the operator 50, it should be stored in the reference book information. Therefore, when the extracted book information is not stored in the reference book information, the control unit 3 notifies the abnormality (S209).

  When the extracted book information is stored in the reference book information, the control unit 3 proceeds to a storage / extracted book confirmation process (S400) described later.

Stored book confirmation process The stored book confirmation process shown in FIG. 6 will be described. In the stored book confirmation process (S300), after the book is stored in the work container 2 from the outside of the depositing / dispensing station 11, the stored book information is accurately detected based on the reference book information, the stored book information, and the internal book information. This is a process in which the control unit 3 confirms whether or not it is completed.

  As shown in FIG. 6, first, the control unit 3 adds the stored book information to the reference book information to create theoretical book information (S301). The theoretical book information is a theoretical value of the book information stored in the work container 2 calculated based on the reference book information and the stored book information.

  Next, the control unit 3 acquires internal book information using the internal antennas 121 to 123 (S302).

  Next, the control unit 3 collates the internal book information with the theoretical book information (S303).

  When the internal book information and the theoretical book information match, the control unit 3 displays the book information of the book that has been put in and out and the number of books contained in the container, and ends (S304).

  When the internal book information and the theoretical book information are different, the control unit 3 raises and rotates the work container 2 by a rotation mechanism (not shown). In addition, the control unit 3 re-acquires internal book information by the internal antennas 121 to 123 during the rotation of the work container 2 (S305).

  Next, the control unit 3 collates the internal book information with the theoretical book information (S306).

  When the internal book information and the theoretical book information match, the control unit 3 displays the book information stored in the operation terminal 102 and the number of books contained in the container, and ends (S304).

  When the internal book information and the theoretical book information are different, the control unit 3 notifies the abnormality and ends (S307).

  In the present embodiment, the reacquisition step S305 is performed once, and when the internal book information and the theoretical book information are different, an abnormality is notified. However, the reacquisition step S305 may be performed a plurality of times. By performing the reacquisition step S305 a plurality of times, the reading accuracy of the internal book information can be improved.

  By acquiring the internal book information while rotating the work container 2 by the rotation mechanism, it is possible to read while changing the relative position between the internal antennas 121 to 123 and the IC tag of the book 110, thereby improving the reading accuracy. it can.

  Further, by acquiring the internal book information while rotating the work container 2 by the rotating mechanism, the internal antennas 121 to 123 can acquire the signal change information of the book 110 in addition to the internal book information of the book 110. Therefore, since the signal change information of the book 110 can be used to acquire the book information of the book 110, the reading accuracy of the internal book information can be improved.

Storage / Removal Book Confirmation Process The storage / removal book confirmation process shown in FIG. 7 will be described. In the storage / removal book confirmation process (S400), the control unit 3 checks whether or not the book information that has been put in and out can be accurately detected based on the reference book information, the stored book information, the take-out book information, and the internal book information. It is processing to do.

  As shown in FIG. 7, the controller 3 first adds the stored book information to the reference book information, and subtracts the extracted book information to create theoretical book information (S401).

  Next, the control unit 3 acquires internal book information through the internal antennas 121 to 123 (S402).

  Next, the control unit 3 collates the internal book information with the theoretical book information (S403).

  When the internal book information and the theoretical book information coincide with each other, the control unit 3 displays the book information of the book that has been put in and out and the number of books contained in the work container 2 and ends (S404).

  When the internal book information and the theoretical book information are different, the control unit 3 raises and rotates the work container 2 by a rotation mechanism (not shown). In addition, the control unit 3 re-acquires internal book information by the internal antennas 121 to 123 during the rotation of the work container 2 (S405).

  Next, the control unit 3 collates the internal book information with the theoretical book information (S406).

  When the internal book information matches the theoretical book information, the control unit 3 displays the book information stored in the operation terminal 102 and the number of books contained in the container, and ends (S404).

  When the internal book information and the theoretical book information are different, the control unit 3 notifies the abnormality and ends (S407).

  In the present embodiment, the reacquisition step S405 is performed once, and when the internal book information and the theoretical book information are different, an abnormality is notified. However, the reacquisition step S405 may be performed a plurality of times. By performing the reacquisition step S405 a plurality of times, the reading accuracy of the internal book information can be improved.

● Book Extraction Processing The book extraction processing shown in FIG. 8 will be described. The book extraction process (S500) is a process for detecting that the operator 50 has taken out the book 1102 from the book 110 accommodated in the work container 2.

  As shown in FIG. 8, first, the operator 50 inserts his / her hand into the communication path 200 from the outside of the depositing / dispensing station 11 (S501).

  Next, the second detector 15 detects the presence of the hand of the operator 50 inserted into the work container 2 in step S501 and turns on (S502).

  The operator 50 inserts a hand into the container accommodating portion 12 (S503).

  The first detector 14 detects the presence of the hand of the operator 50 inserted into the work container 2 in step S501 and is turned on (S504).

  The operator 50 grasps the book 1102 by hand and takes out the book 1102 from the work container 2 (S505). At this time, the hand of the operator 50 exists in the communication path 200.

  The first detector 14 detects that the hand of the operator 50 has left the work container 2 in step S505, and is turned off (S506).

  The gate antennas 131 and 132 start acquiring signal change information of the IC tag of the book 1102 in the communication path 200 (S507).

  Next, the control unit 3 acquires the extracted book information of the book 1102 whose signal is changing based on the signal change information (S508). Here, the control unit 3 waits for an operation of the operator 50.

  When the operator 50 takes the book 1102 out of the banking station 11 (S509), the second detector 15 is turned off (S510).

Next, the control unit 3 confirms the presence / absence of the extracted book information (S511). Here, when there is no take-out book information, the book take-out process ends (S513).

  When there is extracted book information, the search unit 5 calls the reference book information from the storage unit 4. Further, the search unit 5 searches the extracted book information from the reference book information (S512). Since the book 1102 corresponding to the taken-out book information is a book taken out from the work container 2 by the operator 50, it should be stored in the reference book information.

  When the extracted book information is not stored in the reference book information, the control unit 3 notifies the abnormality (S514).

  When the extracted book information is stored in the reference book information, the control unit 3 proceeds to an extracted book confirmation process (S600) described later.

Extracted book confirmation process The extracted book confirmation process shown in FIG. 9 will be described. The extracted book confirmation process (S600) is a method in which the extracted book information is accurately detected based on the reference book information, the extracted book information, and the internal book information after the book is taken out of the depositing station 11 from the work container 2. This is a process in which the control unit 3 confirms whether or not it is completed.

  As shown in FIG. 9, first, the control unit 3 creates theoretical book information by subtracting the extracted book information from the reference book information (S601).

  Next, the control unit 3 acquires internal book information using the internal antennas 121 to 123 (S602).

  Next, the control unit 3 collates the internal book information with the theoretical book information (S603).

  When the internal book information and the theoretical book information coincide with each other, the control unit 3 displays the taken-out book information and the number of books stored in the work container 2 and finishes (S604).

  When the internal book information and the theoretical book information are different, the control unit 3 raises and rotates the work container 2 by a rotation mechanism (not shown). In addition, the control unit 3 re-acquires internal book information by the internal antennas 121 to 123 during the rotation of the work container 2 (S605).

  Next, the control unit 3 compares the internal book information with the theoretical book information (S606).

  When the internal book information matches the theoretical book information, the control unit 3 displays the book information stored in the operation terminal 102 and the number of books contained in the container, and ends (S604).

  When the internal book information and the theoretical book information are different, the control unit 3 notifies the abnormality and ends (S607).

  In the present embodiment, the reacquisition step S605 is performed once, and when the internal book information and the theoretical book information are different, an abnormality is notified. However, the reacquisition step S605 may be performed a plurality of times. By performing the reacquisition step S605 a plurality of times, the reading accuracy of the internal book information can be improved.

  According to the embodiment described above, in order to identify the book that has moved the gate based on the first presence information, the second presence information, the movement book information, and the signal change information, Can be detected.

  The embodiment described above is an automatic library system for managing books. However, the automatic archive system according to the present invention can also be applied to an automatic archive system that manages documents other than books, such as medical records.

● Automatic library system (2) ●
Next, another embodiment of the automatic archive system according to the present invention will be described with a focus on differences from the above-described embodiment. The present embodiment accommodates the work container and the standby container in the area in the depositing / dispensing station, and the internal antenna reads the IC tag of the book accommodated in the work container and the standby container. Different.

  As shown in FIG. 10, the automatic library system 201 includes a container standby unit 203.

  The container standby unit 203 is an area for storing the standby container 202 in the depositing / dispensing station 211. The container standby unit 203 includes a barcode reader 216. The barcode reader 216 reads the barcode 221 of the standby container 202 stored in the container standby unit 203. The barcode reader 216 is disposed so as to face the right side surface of the standby container 202.

  The barcode reader 216 identifies the standby container 202 accommodated in the container standby unit 203 by reading the barcode 221.

  The storage unit 4 stores internal book information of the work container 2 and reference book information of the standby container 202.

  The control unit 3 acquires the reference book information corresponding to the standby container 202 specified by the barcode reader 216 from the storage unit 4. If there is duplicated book information in the book information read by the internal antennas 121 to 123 and the reference book information of the standby container 202, the duplicated book information is eliminated and used as the internal book information for processing.

  The book information obtained by excluding the book information that overlaps the reference book information of the standby container 202 from the book information of the work container 2 and the standby container 202 is used as the internal book information, so that the book of the standby container 202 is added to the internal book information of the work container 2. It is possible to prevent information from being mixed and to detect internal book information more accurately.

● Automatic library system (3) ●
Next, still another embodiment of the automatic archive system according to the present invention will be described with a focus on differences from the above-described embodiment. The present embodiment will be described first in that the gate antenna receives the signal change information after the first presence information of the first detector is turned off in the extraction process after the book is stored and the book extraction process. Different from the embodiment described above.

  As shown in FIG. 11, the two second detectors 153 to 154 are installed above the gate antennas 131 to 132, respectively. The second detector 153 detects an object passing near the gate antenna 131 disposed on both sides of the communication path 200, and the second detector 154 is a sensor that detects an object passing near the gate antenna 132.

  The second detectors 153 to 154 are, for example, photoelectric sensors. Each of the second detectors 153 to 154 has a light emitting element and a light receiving element. At this time, the light emitting element may be installed above the gate antennas 131 to 132, and the light receiving element may be installed at the base of the gate antennas 131 to 132. In addition, the light emitting element and the light receiving element may be installed above the gate antennas 131 to 132, and a reflecting plate that reflects a light beam from the light emitting element may be installed at the base of the gate antennas 131 to 132. In the present embodiment, there are two second detectors, but there may be one or three or more.

  Since the second detectors 153 to 154 are installed above the gate antennas 131 to 132, only the objects passing through the vicinity of the gate antennas 131 to 132 in the communication path 200 are detected, and the vicinity of the center of the communication path 200 is detected. It does not sense passing objects. In this embodiment, the second detectors 153 to 154 are not used in the extraction process after the book storage and the book extraction process described later. Therefore, when taking out the book, the second detectors 153 to 154 can be prevented from operating by taking out the book through the vicinity of the center of the communication path 200. When storing the books, the second detectors 153 to 154 can be operated by bringing the books close to the gate antennas 131 to 132 in the communication path 200.

● Book Storage Processing The flowchart is the same as FIG. When inserting the book 1101 into the communication path 200 in S102, the operator 50 passes the book 1101 in the vicinity of the gate antennas 131 to 132. Then, the second detectors 153 to 154 detect the book 1101.

  In previous embodiment, the 2nd detectors 151-152 were installed in the front side of the communication path 200 outside the depositing station 11. Therefore, when the gate antennas 131 to 132 cannot acquire the signal change information, it is necessary for the operator 5 and the book 1101 to exit the communication path 200 and then enter the communication path 200 again. However, in the present embodiment, the operator 50 may reciprocate the book 1101 in the vicinity of the second detectors 153 to 154. That is, the operator 50 and the book 1101 do not need to go out of the communication path 200. Therefore, the books 1101 can be quickly detected by the second detectors 153 to 154.

Extraction process after book storage The extraction process after book storage shown in FIG. 12 will be described. The extraction process after storing the book (S700) is a process for detecting that the operator 50 has extracted the book 1102 from the work container 2 after storing the book. Here, the book 1102 is an example of a book taken out from the work container 2 by the operator 50. At the start of the extraction process (S700) after storing the book, the operator 50's hand is in the work container 2 and the first detector 14 is in the ON state.

  The operator 50 grasps the book 1102 in the work container 2 and removes it from the container accommodating portion 12 (S701). The first detector 14 that has been turned on detects that the hand of the operator 50 has moved away from the container housing unit 12 in step S701 and is turned off (S702).

  The gate antennas 131 to 132 acquire the signal change information of the IC tag of the book 1102 in the communication path 200 for a predetermined time after the first detector 14 is turned off (S703).

  Next, the control unit 3 acquires the extracted book information of the book 1102 whose signal is changing based on the signal change information (S704).

  Next, the control unit 3 confirms the presence / absence of the extracted book information (S705). Here, when there is no extracted book information, the control unit 3 proceeds to a stored book confirmation process (S300) shown in FIG.

  When there is the extracted book information, the search unit 5 calls the reference book information corresponding to the work container 2 specified by the barcode reader 16 from the storage unit 4. In addition, the search unit 5 searches the extracted book information from the reference book information (S706).

  Since the book 1102 corresponding to the taken-out book information is a book taken out from the work container 2 by the operator 50, it should be stored in the reference book information. Therefore, when the extracted book information is not stored in the reference book information, the control unit 3 notifies the abnormality (S707).

  When the extracted book information is stored in the reference book information, the control unit 3 proceeds to the extracted book confirmation process (S400) shown in FIG.

● Book Extraction Processing The book extraction processing shown in FIG. 13 will be described. The book extraction process (S800) is a process of detecting that the operator 50 has taken out the book 1102 from the book 110 accommodated in the work container 2.

  First, the operator 50 inserts a hand into the container accommodating part 12 (S801).

  The first detector 14 detects the presence of the hand of the operator 50 inserted into the communication path 200 in step S801 and turns on (S802).

  The operator 50 grasps the book 1102 by hand and takes out the book 1102 from the work container 2 (S803).

  The first detector 14 detects that the hand of the operator 50 has moved away from the container storage unit 12 in step S803 and enters an off state (S804).

  The gate antennas 131 to 132 acquire the signal change information of the IC tag of the book 1102 in the communication path 200 for a certain time after the first detector 14 is turned off (S805).

  Next, the control unit 3 acquires the extracted book information of the book 1102 whose signal is changing based on the signal change information (S806).

  Next, the control unit 3 confirms the presence / absence of the extracted book information (S807). Here, when there is no take-out book information, the book take-out process ends (S809).

  When there is extracted book information, the search unit 5 calls the reference book information from the storage unit 4. In addition, the search unit 5 searches the extracted book information from the reference book information (S808). Since the book 1102 corresponding to the taken-out book information is a book taken out from the work container 2 by the operator 50, it should be stored in the reference book information. When the extracted book information is not stored in the reference book information, the control unit 3 notifies the abnormality (S810).

  When the extracted book information is stored in the reference book information, the control unit 3 proceeds to the extracted book confirmation process (S600) shown in FIG.

  According to this configuration, the control unit 3 is configured to receive the signal change information during a predetermined time after the first detector 14 is turned off, so that the second detector can be used when the book is taken out. The operation of is unnecessary, and the system becomes simple.
