<First embodiment>
[Overall configuration of storage system]
1 to 3 schematically show the configuration (storage system) when the shield box according to the first embodiment of the present invention is combined with the storage to be systematized. 2] is a front view illustrating a state in which the opening/closing door 3 is opened (when the door is open). [FIG. 2 and 3 respectively illustrate a state in which the opening/closing door 3 is closed (when the door is closed), wherein FIG. 2 is a perspective view and FIG. 3 is a front view.

As shown in FIGS. 1 to 3, in the storage system according to the present embodiment, for example, a storage 1 and a storage 1 are provided separately from the storage 1, and stored in a storage room 20 of the storage 1. possible shield box (electromagnetic shield part) S, and

The shield box S includes a box main body H having high shielding properties against radio waves (electromagnetic waves) of a specific frequency (for example, 920 MHz and 13.56 MHz), and an RFID system (management device) G for managing stored items. , is configured with The shield box S is a so-called inner tank box.

In this embodiment, the shield box S is shaped like a box that is one size smaller than the storage room 20 of the storage 1 . As a result, the shield box S can be easily stored in the storage room 20, and a storage capacity equivalent to that of the storage room 20 is ensured.

That is, the storage 1 can completely close the opening/closing door 3 when the shield box S is stored in the storage room 20, as shown in FIGS. Therefore, even when the shield box S is stored in the storage room 20, the storage box 1 can be sealed and airtight by completely closing the opening/closing door 3. As shown in FIG.

In addition, in the storehouse 1 in which the shield box S is stored in the storage room 20, even if the electromagnetic shielding (shielding property) of the refrigerator to be applied is insufficient, the electromagnetic shielding is sufficiently performed in the box body H. A shield space Z can be formed (see, for example, FIG. 5).

[Summary of vault]
First, with reference to FIG. 4, a suitable storage box 1 in combination with the shield box S according to the present embodiment will be described.

FIG. 4 schematically shows a state in which the opening/closing door 3 of a refrigerator applicable as the storage 1 is opened (when the door is open). For example, the storage 1 is preferably a refrigerator that can store bottles B such as chemicals, which are articles (objects to be stored), in a temperature-controlled state so as to maintain a low temperature of about 4°C. It is possible to easily divert existing refrigerators.

The ready-made refrigerator is not particularly limited, but by using a more basic, inexpensive, and very common refrigerator, it is possible to further reduce the cost in the case of systematization.

That is, as shown in FIG. 4, for example, the storage 1 includes a refrigerator body 2 having a storage chamber 20 having an opening 10, and an opening/closing door (one side) for opening and closing the opening 10 of the housing constituting the refrigerator body 2. An opening type single door) 3 is provided. The opening/closing door 3 can be locked and unlocked.

The opening/closing door 3 is not limited to a one-door single-opening type, but can be a two-piece double door, a slide-type opening/closing door, or a shutter-type door.

The refrigerator main body 2 is constructed by using a member whose entire housing is made of resin. As for the refrigerator main body 2, at least the outer peripheral portion of the housing except for the opening/closing door 3 is made of metal.

Here, the refrigerator main body 2 is preferably a box-shaped housing, and includes an upper surface 4, a lower surface (bottom surface) 5, left and right side surfaces 6 and 7, a rear surface (rear surface) 8, and a front surface (opening surface) 9. and have The refrigerator body 2 also has a storage room 20 inside. The storage chamber 20 has a substantially rectangular parallelepiped shape, and has an upper surface 20A, a lower surface (bottom surface) 20B, left and right side surfaces 20C and 20D, and a rear surface 20E as inner surfaces. The front surface 9 of the refrigerator main body 2 corresponds to the inside (rear surface) of the opening/closing door 3 described above.

The refrigerator main body 2 is provided with a temperature adjusting air introduction path 30 for adjusting the temperature inside the storage room 20 along the inner surface of the storage room 20 . The temperature-adjusted air introduction path 30 is for circulating the temperature-adjusted air from a temperature adjuster 31 (described later) into the storage chamber 20 .

The temperature adjuster 31 has a heat exchanger and a heater (not shown), and can adjust the temperature inside the storage chamber 20 within a predetermined range.

At least one shelf board 21 (here, for two stages) is detachably provided in the storage room 20 . By changing the width (interval) of the shelf board 21 in the vertical direction, which is the position in the vertical direction, it is possible to store taller bottles B, and a plurality of bottles B can be stacked and stored in the vertical direction. can also Each shelf board 21 can also store a case made of resin that can store the bottles B, a small shield box Sa, which will be described later, and the like.

When used as a refrigerator, there are no particular restrictions on the arrangement position, shape, number, etc. of the shelf plates 21, and they can be arbitrarily set within a range in which the stored bottles B can be effectively stored at a low temperature. In other words, it is desirable that the bottles B stored in the storage box 1 should be stored in such a manner that there is an appropriate margin (gap) between the bottles B adjacent to each other without narrowing the space between them.

In addition, the storage chamber 20 can store the shield box S in a substantially empty state. That is, in the storage system according to the present embodiment, for example, a refrigerator in which all the shelves 21 of the storage room 20 are removed and the interior of the storage room 20 is almost empty is used as the storage 1 .

By housing and storing the bottle B in the shield box S housed in the housing chamber 20, it is possible to manage the temperature and inventory of the bottle B and ensure sufficient shielding performance.

A control thermometer 60, which will be described later, is further arranged in the storage room 20. As shown in FIG. The control thermometer 60 is for detecting the measured temperature information MM used for temperature adjustment of the storage room 20, and can use a thermocouple, for example. The control thermometer 60 is arranged, for example, at a location sensitive to temperature change where the temperature change is greatest in the storage room 20 .

When the shield box S is stored in the storage chamber 20, the control thermometer 60 transmits the measured temperature information MM to a stock monitoring unit (management control unit), which will be described later, by wireless communication such as Bluetooth (registered trademark). It is good also as a structure which can be provided to M.

The measured temperature information MM may be obtained, for example, by using a bottle thermometer or the like that directly measures the temperature of chemicals or the like contained in the bottle B that is stored. Alternatively, since the chemicals actually stored in the bottle B may be very expensive, the temperature inside a dummy bottle (not shown) is measured using a bottle thermometer or the like as the measured temperature information MM. It may be measured indirectly.

Here, the bottle B is made of a glass container, such as a glass bottle, which is not easily affected by the chemicals contained therein, and which is not easily affected by the chemicals. An RFID tag (IC tag) T is attached in advance to each of the bottles B stored in the storage room 20 and stored in the storage room 20 . The RFID tag T contains, for example, the production number (lot number) of the bottle B, the type (drug name) of the drug contained in the bottle B, or tag information (item information) such as the expiration date of the drug. ) is pre-registered.

In the storage room 20, it is also possible to store boxes containing chemicals and various items other than chemicals by attaching RFID tags in advance, in addition to the bottles B.

A rectangular opening 10 is provided on the front face 9 of the refrigerator main body 2, for example, as shown in FIG. 1 or FIG. For example, a single-opening rectangular opening/closing door 3 for opening/closing the opening 10 is attached to the refrigerator main body 2 so as to be openable/closable using a hinge portion.

The refrigerator main body 2 and the opening/closing door 3 of the opening 10 maintain sealing and heat insulating properties against the outside of the refrigerator. In particular, the opening/closing door 3 can open and close the opening 10 on the front surface 9 of the refrigerator body 2 to either the left or the right, and can close the opening 10 without a gap when closed.

2 and 3, the opening/closing door 3 has a handle 3A, and has translucency such as a glass window so that the interior of the storage compartment 20 of the refrigerator body 2 can be seen even when the door is closed. It has 3R. Metal fingers and packing (not shown) are arranged around the glass window 3</b>R and around the opening 10 of the opening/closing door 3 . Therefore, by closing the opening 10, the opening/closing door 3 can keep the interior of the storage chamber 20 in a sealed state while letting the inside pass through.

[Outline of shield box]
Next, referring to FIG. 5, a shield box S that can be applied as an electromagnetic shield section of the storage system according to the present embodiment will be described.

FIG. 5 shows the configuration of the shield box S with the box body H seen through. That is, the shield box S includes a box main body H in which a shield space Z is secured by an electromagnetic shield, and an RFID system G for managing stock information associated with the insertion and removal of bottles B into and out of the shield space Z. .

The shield box S is provided as a separate body from the stocker 1, and is configured to be able to be stored in the storage room 20 of the refrigerator main body 2 together with the RFID system G, for example.

That is, the box main body H is formed in a box shape that is about one size smaller than the storage chamber 20 by using a mesh made of stainless steel or the like that has a high shielding property against radio waves (electromagnetic waves) of a specific frequency. Alternatively, it may be made of, for example, stainless steel with several through-holes that do not impair the shielding performance. As a result, sufficient air permeability is ensured, so that when the shield box S is stored in the storage room 20, the temperature inside the shield space Z will be in a low temperature state similar to that of the storage room 20. controlled by

The box main body H can be locked and unlocked by a locking mechanism 12 with authentication, which will be described later.

The authentication lock mechanism 12 is, for example, as shown in FIG. 1, a user who has been authenticated brings an authentication card key (authentication ID card, etc.) close to the box body H to lock it. , Conversely, it unlocks the box body H. As the lock mechanism 12 with authentication, for example, an electromagnetic door lock that operates by receiving power supply from a commercial power supply or a power supply unit 55 described later can be adopted.

As the lock mechanism 12 with authentication, for example, a password (personal identification number) input from a touch panel, or a physical feature such as a fingerprint using an image processing technique may be used.

In this way, by providing the authenticated lock mechanism 12, a person other than the authenticated user (also referred to as a non-authenticated person or a third party) can The opening of the shield box S can be prevented. Therefore, the bottle B stored in the shield box S cannot be taken out without permission by a person other than the user. As a result, the storage security of the stored bottles B can be ensured.

Further, when an authenticated user attempts to unlock the box main body H by operating the authentication lock mechanism 12, the authentication result is displayed using the display unit D of the RFID system G, for example. You may make it display. The authentication result to be displayed includes, for example, user information such as a registration number and a user name for identifying the user who took the bottle B in and out.

On the front surface of the box body H, for example, as shown in FIG. Since the shutter part 24 is also configured to have an electromagnetic shielding function, the inside of the shield space Z of the box main body H can be kept in a completely shielded state by closing the shutter part 24 . Moreover, by providing the shutter part 24, the security of the stored bottle B can be further improved.

As the shutter section 24, various types of shutters such as roll type, bellows type, blind type, and partition type can be applied. Further, by making it possible to lock and unlock the box main body portion H by the lock mechanism with authentication, the storage security of the stored bottles B can be made stronger.

In this way, the shield box S, in which the entire periphery of the box main body H is electromagnetically shielded and the inner shield space Z is electromagnetically shielded, is stored in the storage room 20 of the stocker 1. - 特許庁As a result, even if the storage cabinet 1 does not have sufficient electromagnetic shielding properties, the shield space Z can be reliably secured in the storage room 20 while maintaining the low temperature state.

For example, as shown in FIG. 5, the RFID system G includes an antenna (antenna section) A which is placed in a shield space Z and receives radio waves from an RFID tag T attached in advance to each bottle B in the shield space Z. Prepare. The RFID system G also includes a tag reader (tag information reading unit) R that reads tag information of the RFID tag T through wireless communication in a non-contact manner as radio waves are received from the RFID tag T by the antenna A. Further, the RFID system G includes a inventory monitoring unit M that manages inventory information of bottles B, for example, based on the tag information of the read RFID tag T. FIG.

The RFID system G may further include an external communication unit U. As a result, it becomes possible to transmit the monitoring information according to the inventory information of the storage system managed by the inventory monitoring unit M to the outside by radio or wire, and centralized management or collective management at a remote location or the like can be performed. be able to do

Similarly, by providing the display unit D in the RFID system G, it is possible to digitally display inventory information, user information, and the like.

Thus, in the shield box S, one or a plurality of bottles B can be accommodated and stored in the shield space Z of the box main body H. As shown in FIG. Each bottle B contains, for example, a liquid medicine such as a vaccine.

Therefore, the bottles B containing liquid drugs and the like are electromagnetically shielded by being housed in the shield box S, and are stored after being temperature-controlled to a low temperature by the storage box 1. Become.

The antenna A is, for example, a small thin-plate antenna, and is arranged inside the box main body H (within the shield space Z) on the rear surface, one side surface, and the upper surface. Note that the size, number, and position of the antennas A can be optimized according to the dimensions of the box main body H, the strength of the radio wave from the RFID tag T (receiving sensitivity), and the like.

In particular, the box body H is electromagnetically shielded. Therefore, the antenna A can be installed at any position such as the lower surface of the box main body H as long as it is inside the shield space Z.

On the other hand, at least the external communication unit U of the RFID system G is arranged outside the box body H (outside the shield space Z). In particular, when the refrigerator main body 2 of the storage 1 is not electromagnetically shielded, the tag reader R, the inventory monitoring unit M, and the external communication unit U can be installed at arbitrary positions outside the box main body H. It is possible.

For example, when the tag reader R of the RFID system G is installed outside the box body H, the antenna A and the tag reader R are electrically connected via a wired cable (external communication cable) K. . The wired cable K penetrates through the box main body H, and measures to prevent magnetic leakage are applied to the penetrating portion. In other words, it is configured so that electromagnetic waves do not enter the shield space Z through the gap between the penetrating portion and the wired cable K.

The wired cable K is, for example, a magnetically shielded cable in which a metal mesh for magnetic shielding is arranged. By adopting the magnetically shielded cable, in the shielded space Z, electromagnetic waves are prevented from being mixed in through the wired cable K from the outside of the box main body H, or conversely, from leaking (leakage of magnetism). .

In this embodiment, each bottle B stored in the shield space Z of the box main body H of the shield box S stored in the storage room 20 of the storage 1 is provided with an RFID tag T in advance. ing. In each RFID tag T, tag information, which is individual product information related to the bottle B, is registered in advance.

Then, the tag reader R of the RFID system G reads the tag information of each bottle B transmitted from each RFID tag T via the antenna A, transfers the read tag information to the inventory monitoring unit M, is done.

That is, from the tag reader R, irregularly (for example, triggered by the opening/closing door 3 being closed), via the antenna A, to each bottle B stored in the shield space Z, Predetermined inquiries are made. When the opening/closing door 3 is closed and the door is closed, a predetermined inquiry may be made to each bottle B stored in the shield space Z periodically.

In response to this inquiry, the tag information stored in each RFID tag T of each bottle B is transmitted to the antenna A. FIG.

As a result, the tag reader R reads individual tag information, such as the production number (lot number) of each bottle B, the type of drug contained therein, the expiration date, etc., without contact.

In this case, the antenna A of the RFID system G is arranged in a shielded space Z that is electromagnetically shielded. Therefore, the tag information received by the antenna A when the box main body H is closed is only the tag information transmitted from the RFID tag T of the bottle B stored in the shield space Z.

That is, when the opening/closing door 3 is closed, both the box body H and the shutter portion 24 of the shield box S are normally closed. Therefore, by reading the tag information from each bottle B when the opening/closing door 3 is closed, only the tag information of the bottles B stored in the shield space Z can be acquired.

At that time, a plurality of antennas A are arranged at mutually different positions in the shield space Z, and tag information from the RFID tags T of all the bottles B can be received regardless of where each bottle B is located in the shield space Z. By doing so, the tag information can be read more reliably.

The inventory monitoring unit M manages the inventory information of each bottle B based on the individual tag information registered in the RFID tag T of each bottle B read by the tag reader R via the antenna A. .

The inventory monitoring unit M may create monitoring information for each bottle B from the inventory information. The monitoring information is, for example, information transmitted wirelessly or by wire through the external communication unit U to a predetermined information station (not shown) such as an external centralized monitoring center.

In the storage system according to the present embodiment, the shield space Z is completely electromagnetically shielded when the box body H of the shield box S is closed. That is, when the shield space Z is closed, the tag information of the bottle not stored in the shield box S is not erroneously read by the tag reader R.

As a result, by the RFID system G, it is possible to accurately manage the putting in and out of the bottle B with the RFID tag T attached to the shield space Z, and the tag information from the RFID tag T in the shield space Z, such as inventory, can be accurately managed. It is possible to easily acquire accurate inventory information based on

In particular, by enabling management of the date and time when each bottle B is put in and taken out, it is possible to grasp the time during which the bottle is not stored in the stocker 1, and it can be used for quality control of chemicals and the like.

Moreover, when the box main body H of the shield box S is closed, it is possible to easily prevent electromagnetic waves generated when tag information is read from leaking out of the storage box 1 . As a result, it is possible to easily prevent various types of information about the bottles B stored in the storage 1 from inadvertently leaking out of the storage 1 .

[Vault system control block]
Next, with reference to FIG. 6, the control block when systematized will be described.

As illustrated in FIG. 6, the storage system according to the present embodiment includes a storage 1 and a shield box S provided separately from the storage 1 and stored in a storage room 20. It is configured.

The storage 1 is a commercially available general refrigerator, and the refrigerator main body 2 is provided with a temperature regulator 31, a control thermometer 60, an abnormality alarm unit 71, a storage control unit 80, and the like. ing. In addition, it is also possible to additionally provide a power supply unit 55 and a door opening/closing detector (not shown) in the storage cabinet 1 .

The control thermometer 60 is for detecting the measured temperature information MM used for temperature adjustment, and is arranged in the storage chamber 20 near the opening 10 where the internal temperature changes rapidly. The control thermometer 60 is electrically connected to the warehouse control unit 80 and the inventory monitoring unit M of the RFID system G, for example.

The storage control unit 80 is electrically connected to the control thermometer 60, the temperature adjuster 31, the abnormality alarm unit 71, and the like.

The temperature adjuster 31 is controlled by the storage control unit 80 based on the measured temperature information MM from the control thermometer 60, and continuously maintains a low temperature state in which the temperature inside the storage room 20 is constant. It's like Thereby, the temperature of each bottle B is preferably kept at about 4°C.

For example, when the temperature inside the storage room 20 exceeds a predetermined temperature (for example, 6° C.), the abnormality alarm unit 71 turns on an abnormality alarm lamp to warn of an abnormal rise in temperature. Also, when the temperature in the storage room 20 falls below a predetermined temperature (for example, 2° C.), the abnormality warning light is turned on to warn of an abnormal temperature drop. Further, an abnormality alarm sound generating section may be provided for generating an alarm sound when the temperature inside the storage chamber 20 is out of a predetermined control temperature range (for example, 2° C. to 6° C.).

It is also possible to cause the abnormality alarm unit 71 to generate an alarm sound when the open/close door 3 is continuously opened for a preset time.

The measured temperature information MM detected by the control thermometer 60 may be digitally displayed by the display unit D of the RFID system G, for example.

The power supply unit 55 is for supplying power for operation to the shield box S when the shield box S is stored in the storage room 20. For example, the power supply unit 55 uses a non-contact type such as wireless power supply or a connector. It consists of a transmission type power device.

On the other hand, the shield box S is equipped with an RFID system G and an authentication lock mechanism 12, and the inventory monitoring unit M is connected to a reference value storage unit F for storing various reference values.

The authentication lock mechanism 12 is for restricting the box main body H of the shield box S from being opened carelessly, for example, and lock/unlock information RR indicating whether it is in the locked/unlocked state is Output to inventory monitoring unit M.

The RFID system G comprises, for example, as shown in FIG. 5, a tag reader R for reading tag information from an RFID tag T pre-attached to each bottle B, an antenna A, and an inventory monitor M. ing. Further, the RFID system G may include a display unit D, an external communication unit U, and the like.

In the RFID system G, the tag reader R reads the tag information from the RFID tag T of each bottle B stored in the shield space Z via the antenna A, and based on the read tag information, the inventory monitoring unit Inventory information and the like are managed by M.

Further, in the RFID system G, the tag information read by the tag reader R, the display unit D such as stock information based on the tag information, or the transmission of the monitoring information from the external communication unit U to the outside, etc. done.

In the display unit D, for example, based on stock information, it is possible to automatically warn that the expiration date of the medicine contained in the bottle B is approaching.

In particular, when the bottle B taken out from the shielded space Z is returned to the shielded space Z after a predetermined period of time, for example, the potency of the bottle B as a medicine is significantly reduced and It is also possible to call attention to the fact that the storage is unsuitable for storage.

As described above, according to this embodiment, it is possible to easily prevent the electromagnetic waves generated when reading the tag information from leaking out of the storage 1, and various information about the stored bottles B can be obtained. It is possible to easily suppress leakage to the outside of the refrigerator.

That is, in the storage system according to the first embodiment, the shield box S is stored in the storage chamber 20 of the storage 1, and the bottle B can be stored in the shield space Z. As a result, it is possible to use a general refrigerator as the storage 1, and the shield box S that can be stored in the storage room 20 of the storage 1 has a simple configuration equipped with the RFID system G. can do. Therefore, by reading the tag information without contact, it is possible to realize a storage system that can easily manage the bottles B to be stored accurately at a lower cost.

In particular, by reading the tag information while the shield space Z is closed, it is possible to easily prevent the leakage of the electromagnetic waves generated during the reading of the tag information to the outside of the stocker 1 .

In the storage system according to the first embodiment described above, the case where one shield box S is stored in the storage room 20 of the storage 1 has been described as an example, but the present invention is not limited to this. For example, it is possible to configure a plurality of shield boxes to be stored at the same time.

<Second Embodiment>
FIG. 7 schematically shows an application example of a storage system systemized by combining a shield box according to the second embodiment of the present invention with a storage. Here, bottles B stored in a large storage system installed in a dispensing room 50 of a hospital or the like are transported together with a shield box Sa to a small storage system installed in a home, a treatment room, a sick room 51, or the like. A case of transferring (conveying) is illustrated.

The same or similar reference numerals are assigned to the same parts as those of the storage system shown in the first embodiment, and detailed description thereof will be omitted. For example, each storage 1 in a large storage system and a small storage system may be different in size, but they are all substantially the same as the storage 1 in the storage system shown in the first embodiment. It is configured.

In FIG. 7, a small shield box Sa, which is an electromagnetic shielding part, is a storage box (for example, a main storage box) 1 in a large storage system or a storage box (for example, a sub storage box) in a small storage system. stored in each storage room 20 of the warehouse) 1. The storage room 20 of the main storage 1 can store, for example, six small shield boxes Sa at the same time. The storage room 20 of the sub storage 1 can store, for example, one or several small shield boxes Sa.

In this application example, for example, one small shield box Sa is taken out from the main storage 1 such as the dispensing room 50 and stored in a transport container (transport device) 40 and transported. After being transported to the patient's room 51 or the like, the small shield box Sa is stored in the storage room 20 of the sub storage 1 . As a result, the bottles B housed in the small shield box Sa can be stored in the sub storage 1 while maintaining the low temperature.

A small shield box Sa provided separately from the storage 1 basically has the same configuration as the shield box S shown in FIG. 5 except for the size of the box main body Ha. .

That is, as shown in FIG. 8, for example, the small shield box Sa includes a box main body Ha in which a shield space Z is secured, and an RFID system for managing inventory information associated with the insertion and removal of bottles B into and out of the shield space Z. G and.

The box main body Ha has a substantially rectangular parallelepiped box shape. The box main body Ha is made of stainless steel mesh or the like, which has high shielding properties against radio waves (electromagnetic waves) of a specific frequency. Alternatively, it may be made of, for example, stainless steel with several through-holes that do not impair the shielding performance. This ensures sufficient ventilation of the box main body Ha.

FIG. 11 shows the flow of processing when the small shield box Sa is carried into the sub storage 1. As shown in FIG.

In the hospital room 51 or the like, the small shield box Sa taken out of the transportation container 40 is immediately stored in the sub storage 1 in the small storage system.

In this case, the storage control unit 80 first checks whether or not the opening/closing door 3 of the sub storage 1 is opened (step ST21). The processing in step ST21 is repeated until it is determined that the opening/closing door 3 is open in the sub storage 1 (NO in step ST21).

In step ST21, when it is determined that the opening/closing door 3 is opened (YES in step ST21), the small shield box Sa is stored in the storage room 20 (step ST22). If the small shield box Sa is not to be stored (NO in step ST22), the process is terminated.

On the other hand, when the small shield box Sa is stored in the storage room 20 (YES in step ST22), in step ST23, the storage control unit 80 checks whether the open/close door 3 is closed. In the sub storage 1, the processing in step ST23 is repeated until it is determined that the opening/closing door 3 is closed (NO in step ST23).

Assume that it is determined that the opening/closing door 3 is closed in the sub storage 1 (YES in step ST23). Then, in the stored small shield box Sa, tag information is read from the RFID tag T by the antenna A of the RFID system G and the tag reader R (step ST24).

After the inventory information is generated by the inventory monitoring unit M based on the read tag information, the generated inventory information is sent to the external information station IS by the external communication unit U of the RFID system G. is sent (step ST25).

In this way, a series of processing related to loading is completed. Thereafter, the bottles B transported to the sub-storage 1 will be stored and managed in this sub-storage 1 .

In the sub storage 1, the tag information is read after the opening/closing door 3 is closed, so that the leakage of electromagnetic waves to the outside of the sub storage 1 can be reliably prevented. .
