In relation to the above, Patent Document 1 discloses an article management system using an RFID (radio frequency identifier) tag.

JP-A-2007-62932

The article management system described in Patent Document 1 attaches an RFID tag in which identification data is recorded to an article stored in a storage, and identifies data from the RFID tag attached to the article by a reader / writer provided in the storage. The inventory of goods is managed by reading.

However, inventory management of goods using RFID tags may erroneously detect (misread) RFID tags outside the storage due to radio waves transmitted from the reader / writer leaking to the outside of the storage. In that case, there is a problem that proper inventory management is hindered. In order to prevent this, it is necessary to correctly inspect misreading in the storage, but at present, there is a problem that there is no method for efficiently inspecting misreading.

That is, it is possible to simultaneously inspect for misreading at a plurality of positions. As a result, it becomes possible to improve the inspection efficiency of misreading. Further, since the range in which misreading can be detected in one inspection can be widened, it is possible to efficiently identify the range in which misreading can occur.

Further, in the present invention, the holding body may hold the holding member in an adjustable position in the second direction. Thereby, for example, when inspecting misreading, the inspection device is arranged so that the inspection device and the storage are arranged in the second direction, and the position of the holding member in the second direction is adjusted by adjusting the storage. It is possible to simultaneously carry out a plurality of misreading tests at a position separated from the vehicle by an arbitrary distance. This makes it possible to inspect at the inspection position according to the target specifications of the storage. The inspection device may be arranged so that the inspection device and the storage are arranged in the first direction at the time of inspection for misreading.

Further, in the present invention, the plurality of holding bodies may be configured so that their positions in the vertical direction can be adjusted. Thereby, the range for inspecting misreading can be adjusted in the vertical direction according to the height of the storage.

Next, an embodiment of the present invention will be described with reference to the drawings. However, the embodiments described below are examples for carrying out the present invention, and the dimensions, materials, shapes, relative arrangements, etc. of the components described in the present embodiment are not particularly specified. As far as the limit is concerned, the technical scope of the invention is not limited to them.

FIG. 1 is a diagram showing a mode of distribution of the drug X according to the present embodiment. In FIG. 1, block 100 indicates a pharmaceutical manufacturer, block 200 indicates a distributor, and block 300 indicates a medical institution such as a hospital or pharmacy. The distributor 200 here may include all the companies that intervene between the pharmaceutical manufacturer 100 and the medical institution 300, such as wholesalers and carriers. Here, since strict temperature control is required for the drug X in the specialty area produced by the drug manufacturer 100, the distributor is housed in a cold storage container 2 as an environment maintenance and transportation means capable of temperature control during movement. Purchased in 200. Further, in the distributor 200, the drug X is stored in a refrigerated storage 1 (hereinafter, storage 1) as an environmental maintenance storage means in a temperature-controlled state until it is sold. Then, when the sales destination medical institution 300 is determined, the product is discharged from the storage 1 and transported to the medical institution 300 again in a state of being stored in the cold storage container 2. Then, in the medical institution 300, the drug X is taken out from the cold storage container 2 and stored and stored in the storage 1 of the medical institution 300, and when used by a patient, it is taken out from the storage 1 and administered. To.

An RFID tag 10a on which the ID (identification information) of the drug X is recorded is attached to the drug X (the drug X itself or the package of the drug X). The RFID tag 10a corresponds to the identification element in the present invention, and is a tag-shaped medium in which an IC and an antenna are incorporated. The identification information recorded on the RFID tag 10a includes, for example, expiration date information indicating the expiration date for properly using the drug X, appropriate temperature information indicating the range of ambient temperature defined for properly storing the drug X, and the like. including.

Further, in the cold storage container 2 and the storage 1, the RFID reader 10 capable of detecting the identification information of the drug X by the RFID tag 10a and the temperature history information are acquired by measuring the internal temperature of the cold storage container 2 and the storage 1. A possible temperature sensor 20 is provided. The RFID reader 10 and the temperature sensor 20 transmit the acquired information to the information management device 6 by wireless communication. The information management device 6 records this information as needed.

As a result, after the drug X is manufactured and shipped by the drug manufacturer 100 (purchased from the distributor 200), the distribution process from the drug manufacturer 100 to the distributor 200, the storage process at the distributor 200, and the medical treatment from the distributor 200. In the distribution process up to the institution 300 and the storage process in the medical institution 300, it is possible to confirm whether or not the drug X having a predetermined ID is stored in the cold storage container 2 or the storage 1 and the temperature is appropriately controlled. It becomes. As a result, for example, even if the drug X becomes surplus at the medical institution 300 due to the transfer of a patient, death, etc., and the medical institution 300 requests a return, the drug manufacturer 100 or the distributor 200 returns and re-enters the drug. It is possible to determine whether or not to sell. Specifically, the drug manufacturer 100 or the distributor 200 determines whether or not to return the drug based on the storage information, the temperature history information, the expiration date information of the drug X and the appropriate temperature information recorded on the RFID tag 10a. .. For example, the possibility of returning the product may be determined based on at least one of the conditions of the time outside the specified temperature range, the degree of deviation, and the remaining period until the expiration date. For example, if there is a time when the ambient temperature of the drug X deviates from the specified temperature range (for example, 2 to 8 ° C, 1 to 30 ° C, 15 to 25 ° C, etc.) in the temperature history information, other conditions may be applied. Regardless, it does not matter if it is non-returnable. It is desirable that the above-mentioned conditions for determining whether or not to return the product should be determined based on the package insert (specifications) of the drug X and GDP (Good Distribution Practice). Further, the above-mentioned determination of whether or not to return the product may be automatically performed by the information management device 6, and the result of whether or not the product may be returned may be automatically displayed.

Next, the mode of acquiring the identification information in the above-mentioned storage 1 will be described. FIG. 2 is an overall view of the storage 1. As shown in FIG. 2, the storage 1 has a substantially rectangular parallelepiped shape as a whole, and the box-shaped main body 11 in which a space for accommodating the drug X as a storage object is formed and the user It is composed of a door portion 12 provided on the main body portion 11 so as to be openable and closable so that the drug X can be taken in and out. The door portion 12 can be opened and closed by hinge-connecting one end to the front surface of the main body portion 11. Hereinafter, with respect to the storage 1, the side where the door portion 12 is located is referred to as the front side (front) of the storage 1. The door portion 12 is provided with a window portion 13 made of a highly translucent glass material or the like. As a result, the user can visually recognize the quantity and state of the drug X in the storage 1 from the outside of the storage 1. Further, a rubber packing 14 for sealing the storage 1 by contacting the front surface of the main body 11 when the door 12 is closed is provided on the peripheral edge of the back surface of the door 12. There is.

The RFID reader 10 and the temperature sensor 20 described above are provided at predetermined positions in the storage 1. The RFID reader 10 is composed of a control unit and an antenna, and transmits radio waves from the antenna to at least the entire internal space of the storage 1. As a result, all the antennas of the RFID tags 10a in the storage 1 can receive radio waves. The RFID tag 10a according to the present embodiment employs a so-called passive method, and when the antenna of the RFID tag 10a receives a radio wave from the RFID reader 10, electric power is generated by a rectifying action, and the generated electric power is used for identification information. Is put on the radio wave and the response is transmitted from the antenna. The RFID reader 10 that receives the radio wave transmitted in response from the RFID tag 10a by its own antenna processes the information by the control unit. As a result, the RFID reader 10 acquires the identification information of the drug X. Radio waves in a predetermined frequency band are used for communication between the RFID reader 10 and the RFID tag 10a described above. Although the predetermined frequency band is not specifically limited, for example, a radio wave in a high frequency region of 920 MHz may be used. By using radio waves in a high frequency region with high radio wave strength, the RFID tag 10a attached to the drug X can be detected regardless of the posture and position of the drug X in the storage 1.

Here, as described above, in order to determine whether or not the drug X having a predetermined ID is stored in the predetermined storage 1, only the RFID tag 10a in which the RFID reader 10 is inside the storage 1 is used. Must be detected accurately. If the RFID reader 10 detects (misreads) the RFID tag 10a outside the storage 1, the drug X with the misread RFID tag 10a is not actually stored in the storage 1. Nevertheless, since it is recognized that it is stored in the storage 1, there is a risk that proper inventory control and temperature control will be hindered.

In such a misreading, the radio wave transmitted from the RFID reader 10 leaks to the outside of the storage 1, the leaked radio wave is received by the RFID tag 10a, and the RFID reader 10 receives the radio wave signal responded by the RFID tag 10a. Caused by receiving. Although the radio wave transmitted from the RFID reader 10 is attenuated in inverse proportion to the distance from the source, the radio wave strength sufficient to generate electric power and operate the RFID tag 10a at a position close to the storage 1 is still present. May have. That is, if the RFID tag 10a exists at a position close to the storage 1, the RFID reader 10 may misread the RFID tag 10a. Hereinafter, the range in which the RFID tag 10a outside the storage 1 can be misread is referred to as a misread range. When such misreading occurs, the drug X is taken out from the storage 1 and temporarily placed within the misreading range for temporary work, or a plurality of storages 1 are adjacent to each other or face each other. When the drug X is installed within the misreading range of the installed storage 1, the drug X may be stored in a nearby storage 1. On the other hand, it is possible to avoid misreading by operating so that the drug X and another storage 1 are not placed within the misreading range. For example, there is an operation method in which the drug X is not placed in a place within 50 cm from the storage 1. However, if the storage 1 is installed in a place where a sufficient area is secured, such an operation is possible, but the site area is small and the installation place of the storage 1 cannot be secured sufficiently wide. Then, the fact is that the above-mentioned operation is difficult.

In view of the above circumstances, in order to fundamentally prevent misreading of the RFID tag 10a, development of a storage 1 in which the misreading range is narrowed to a predetermined range or less is being promoted. The predetermined range is a range defined as a reference specification at the time of manufacturing, and is a distance range in which misreading may be detected (hereinafter, an allowable misreading range). The permissible misreading range is a range in which it is practically possible to operate the drug X and another storage 1 so as not to place the drug X or another storage 1 within the range, and is determined based on a general installation space and operation method.

While the development of such a storage 1 is being promoted, it is necessary to quantitatively inspect the misreading range of the prototype storage 1. Further, in the mass production process of the storage 1, whether the misreading range does not exceed the permissible misreading range which is the shipping standard, that is, whether the produced storage 1 detects the RFID tag 10a outside the permissible misreading range. It is necessary to inspect whether or not it is shipped before shipping.

In order to inspect for misreading at a certain position, it is necessary not only to measure the leaked radio wave but also to determine whether or not the RFID reader 10 detects the actual RFID tag 10a placed at the position. Further, in order to inspect the misreading range, it is necessary to perform the misreading inspection at a plurality of positions having different directions and distances from the storage 1. However, conventionally, there has been no inspection device 3 capable of efficiently performing a misreading inspection at a plurality of positions. Specifically, by changing the position of one RFID tag 10a, misreading at a plurality of positions was inspected one by one. Therefore, there is a problem that it takes a lot of time and labor for the misreading inspection for one storage unit 1.

By using the device (hereinafter, inspection device) 3 for inspecting the misreading of the storage 1 according to the present embodiment for the above problem, it is possible to efficiently carry out the misreading inspection of the storage 1. .. Hereinafter, the inspection device 3 according to the present embodiment will be described in detail. FIG. 3 is a diagram showing an overall view of the inspection device 3 according to the present embodiment. Further, FIG. 4 is a diagram showing a holding body 31 of the inspection device 3. Hereinafter, in the description of the inspection device 3, the right direction visually recognized in FIG. 3 is referred to as the front side (front) of the inspection device 3. As shown in FIG. 3, the inspection device 3 is provided with a plurality of RFID tags 10a to which individual identification information is attached. The RFID tag 10a is the same product as the RFID tag 10a attached to the pharmaceutical product X, and is distributed and arranged in the inspection device 3 in the left-right direction, the front-back direction, and the up-down direction. In the misreading inspection according to the present embodiment, the misreading range is specified based on the position of the RFID tag 10a detected by the RFID reader 10 of the storage 1 with the inspection device 3 adjacent to the storage 1. Further, the inspection device 3 according to the present embodiment is configured so that the inspection operator can easily grasp the distance from the storage 1 to each RFID tag 10a by the structure described later. The left-right direction in the inspection device 3 corresponds to the "first direction" of the present invention, and the front-rear direction, which is a direction perpendicular to the left-right direction, corresponds to the "second direction" of the present invention.

As shown in FIG. 3, the inspection device 3 has a substantially rectangular parallelepiped shape as a whole, and is composed of a plurality of holding bodies 31 provided with a plurality of RFID tags 10a and a frame body 32 for holding the holding bodies 31. Has been done. The frame body 32 has four columns 32a that stand upright from the ground, and a support member 32b attached to each column 32a. The frame body 32 has a substantially rectangular parallelepiped outer shape formed by four columns 32a, and the holding body 31 is held by supporting the holding body 31 from below by the supporting member 32b. Further, as shown in FIG. 4, the holding body 31 is configured by horizontally mounting a plurality of holding members 311 having a band shape on an outer frame 312 forming a rectangular frame in a top view. RFID tags 10a are arranged at equal intervals on the holding member 311 along the extending direction of the band shape. As a result, it is possible to inspect at which position in the left-right direction the misreading occurs. Further, on the holding body 31, a plurality of holding members 311 are arranged side by side in the front-rear direction so as to be parallel to the left-right direction. As a result, it is possible to inspect at which position in the front-rear direction the misreading occurs. Then, as shown in FIG. 3, the inspection device 3 can inspect at which position in the vertical direction the misreading occurs because the plurality of holding bodies 31 are arranged side by side in the vertical direction. it can. With such an inspection device 3, a three-dimensional misreading inspection becomes possible. A caster 33 is provided at the lower end of the support column 32a to make the inspection device 3 movable.

As shown in FIG. 4, a plurality of RFID tags 10a are arranged on the holding member 311 in a straight line. The holding member 311 according to the present embodiment is provided with six RFID tags 10a at equal intervals along the extending direction of the holding member 311. However, the number of RFID tags 10a provided on one holding member 311 is not limited to this, and can be changed as appropriate. The RFID tag 10a may be one. The RFID tag 10a may be detachably fixed to the holding member 311 at an arbitrary position by a hook-and-loop fastener, whereby the quantity of the RFID tags 10a and the distance between the RFID tags 10a can be freely adjusted. Good. Further, the holding member 311 is formed with a sensor pocket 311a which is a hole having a predetermined size. The probe or antenna of the radio field strength sensor 40 for measuring the radio field strength, which will be described later, is detachably attached to the sensor pocket 311a. Sensor pocket 31
1a corresponds to the sensor holding portion of the present invention.

The outer frame 312 constituting the holding body 31 is located on the front side and extends in the left-right direction in the inspection device 3, and is located on the rear side facing the front frame member 312a and in the left-right direction. A rectangular frame is formed by an extending rear frame member 312b, and a pair of first horizontal frame members 312c and second horizontal frame members 312d that are located in the left-right direction and extend in the front-rear direction. As will be described later, the misreading inspection according to the present embodiment is carried out in a state where the front end surface of the front frame member 312a is in contact with the storage 1. The front end surface of the front frame member 312a corresponds to the contact portion of the present invention.

Further, the outer frame 312 slidably supports a plurality of holding members 311 in the front-rear direction. Specifically, the first horizontal frame member 312c and the second horizontal frame member 312d are formed with slide grooves 312e, which are grooves capable of receiving the ends of the holding member 311, along the front-rear direction. The holding member 311 is slidably supported in the slide groove 312e by being accepted by the slide grooves 312e formed in the first horizontal frame member 312c and the second horizontal frame member 312d at both ends of the 311. Since the holding member 311 can slide in the front-rear direction, the position of the RFID tag 10a in the front-rear direction can be adjusted according to the inspection range. As an example, the inspection device 3 according to the present embodiment is provided with five holding members 311 for each holding body 315. However, the quantity of the holding member 311 is not limited to this. The number of holding members 311 may be one.

Further, a scale portion 312f is formed on the upper surface of the first horizontal frame member 312c along the front-rear direction, and a scale indicating the distance from the front end surface of the front frame member 312a is displayed on the scale portion 312f. There is. As shown in FIG. 4, the scale is displayed over the entire sliding range of the holding member 311. The interval between the scales can be appropriately selected. Since the scale portion 312f is provided on the first horizontal frame member 312c, the inspector can adjust the front-rear position of the plurality of holding members 311 while referring to the scale. Further, since the scale indicates the distance from the front end surface of the front frame member 312a that comes into contact with the storage 1 in the misreading inspection, the inspector grasps the distance of the holding member 311 from the storage 1 in the misreading inspection. It becomes easy. As a result, the inspector can easily grasp the distance of the RFID tag 10a from the storage 1. The scale displayed on the scale unit 312f may be any scale as long as it serves as a guide for determining the position of the RFID tag 10a in the front-rear direction. The scale unit 312f may display the scale by letters, numbers or marks printed or stamped at predetermined intervals. Further, the scale portion 312f may be provided on the second horizontal frame member 312d.

A plurality of mounting holes are provided in each of the columns 32a at predetermined intervals, and a support member 32b that supports the holding body 31 from below can be mounted in each mounting hole. The holding body 31 is held by the frame body 32 by being supported by the supporting member 32b from below. The height position in which the holding body 31 is supported can be changed by appropriately selecting the position of the mounting hole for mounting the support member 32b. As a result, the vertical positions of the holding bodies 31 can be adjusted according to the height of the storage 1 to be inspected and the allowable misreading range. The holding body 31 may be connected to the support column 32a by a slide mechanism or the like, and may be configured so that the vertical position can be freely adjusted. Further, in the inspection device 3 according to the present embodiment, the holding body 31 is composed of four stages as an example, but the number of stages of the holding body 31 is not limited to this. The number of holding bodies 31 held by the frame body 32 may be one.

[Inspection method]
An erroneous reading inspection using the inspection device 3 according to the present embodiment will be described. FIG. 5A is a diagram showing a state when a misreading inspection using the inspection device 3 is viewed from above. As shown in FIG. 5A, in the misreading inspection, the inspection devices 3 are sequentially arranged at a plurality of positions with respect to the storage 1, and the misreading inspection is performed at each position. In this example, the inspection range is the area around the storage 1 other than the rear. The vault is generally likely to be installed with its back side close to the wall, in which case it is unlikely that the RFID tag will be placed behind the vault. Therefore, in this example, the rear part of the storage 1 is excluded from the inspection range. The inspection device 3 is sequentially arranged at positions of the storage 1 in the right direction, the diagonally right front direction, the front direction, the diagonally left front direction, and the left direction. The order in which the inspection devices 3 are arranged is not particularly limited. Hereinafter, as shown in FIG. 5B as an example, a case where the misreading inspection is performed from the front of the storage 1 will be described.

FIG. 6 is a diagram showing a procedure for misreading inspection. First, in step S01, the inspection device 3 is arranged so that the frame 32 is adjacent to the storage 1 (inspection device arrangement step). At this time, the front surface of the inspection device 3 is arranged so as to face the front surface of the storage 1. That is, in this state, the storage 1 is located in the front direction of the inspection device 3. As a result, the holding members 311 are located side by side in the front direction of the storage 1, so that the RFID tags 10a are lined up in the front direction of the storage 1. Further, in this state, the inspection device 3 is positioned by the front end surface of the holding body 31 coming into contact with the storage 1 from the front. As a result, the scale displayed on the scale unit 312f indicates the distance from the front surface of the storage 1.

Next, in step S02, the position of the RFID tag 10a in the inspection device 3 is determined according to the size and inspection range of the storage 1 to be inspected (identification element position adjustment step). The vertical position of the RFID tag 10a is determined by the vertical position of the holding member 411. The vertical position of the holding body 31 is adjusted by selecting the position of the mounting hole for mounting the support member 32b. In this example, a plurality of holding bodies 31 are arranged at equal intervals in the vertical direction. At this time, the vertical position of the holding body 31 and the distance between the holding bodies 31 are determined according to the height of the storage 1, the inspection range, and the required inspection accuracy. As a result, the RFID tags 10a are arranged at equal intervals in the inspection range in the vertical direction. Further, the position of the RFID tag 10a in the front-rear direction is determined by the front-rear position of the holding member 311 in each holding body 31. The front-rear position of the holding member 311 can be adjusted by sliding the holding member 311. In this example, the holding members 311 are adjusted so as to be arranged at equal intervals in the front-rear direction. As a result, the RFID tags 10a are arranged at equal intervals in the front direction of the storage 1. Further, the range in which the holding members 311 are arranged in the front-rear direction and the distance between the holding members 311 are determined according to the inspection range and the required inspection accuracy. For example, when the permissible misreading range of the RFID tag 10a in the front-rear direction is within 10 cm from the storage 1 to 10 cm, the foremost holding member 311 is arranged at a position 10 cm from the front end portion and held at equal intervals behind it. The member 311 is arranged. In this way, the positions of the RFID tags 10a provided in the inspection device 3 are arranged at equal intervals according to the inspection range of the storage 1. The above procedure may be performed in the reverse order of the inspection device arrangement step and the identification element adjustment step.

Next, in step S03, the storage 1 was held by the frame 32 by operating the RFID reader 10 of the storage 1 in a state where the inspection device 3 was arranged and the position of the RFID tag 10a was adjusted. By inspecting whether or not the RFID tag 10a is detected, the presence or absence of misreading is determined and the misreading range is specified (misreading range specifying step). Specifically, the determination device 4 acquires the identification information of the RFID tag 10a detected by the RFID reader 10. The determination device 4 identifies the detected RFID tag 10a based on the acquired identification information, and causes the display device 5 to output the result. The inspector identifies the misread range based on the position of the detected RFID tag 10a displayed on the display device 5. As described above, in the misreading inspection method according to the present embodiment, a plurality of RFID tags 10a are linearly arranged and fixed to the holding member 311 in the left-right direction, and the holding members 311 are arranged in the front-rear direction and the up-down direction to form the frame 32. It is inspected whether or not the storage 1 detects the RFID tag 10a when the frame 32 is held and adjacent to the storage 1. As a result, it is possible to simultaneously check for misreading at a plurality of positions. Further, since the inspection device 3 is arranged so that the front surface of the inspection device 3 faces the storage 1, the holding members 311 are lined up toward the storage 1. As a result, by adjusting the position of the holding member 311, it is possible to carry out the inspection at a position separated from the storage 1 by an arbitrary distance.

The above steps are also carried out in the right direction, the diagonally forward right direction, the diagonally forward left direction, and the left direction of the storage 1. Here, the inspection device 3 can be easily moved by providing the casters 33. As a result, the arrangement of the inspection device 3 can be smoothly switched, so that the time required for the inspection can be carried out. In the arrangement process in each direction, the inspection device 3 is arranged so that the front surface faces the storage 1. By specifying the misreading range in the right direction, the diagonally forward right direction, the diagonally forward left direction, and the left direction of the storage 1, the misreading range in the entire inspection range can be specified.

The position where the inspection device 3 is arranged is not limited to the above, and can be appropriately selected according to the inspection range. For example, if it is sufficient to inspect misreading near the front of the storage 1, the inspection may be performed only in the front of the storage 1.

Further, in the above description, the misreading inspection is performed using one inspection device 3, but the misreading inspection may be performed using a plurality of inspection devices 3. For example, in the misreading inspection, the five inspection devices 3 may be arranged in the right direction, the diagonally forward right direction, the front direction, the diagonally left forward direction, and the left direction, respectively, and the inspection may be performed at the same time. Thereby, the inspection time can be further shortened.

[Action / Effect]
As described above, the inspection device 3 according to the present embodiment can hold the holding member 311 capable of arranging and fixing the plurality of RFID tags 10a linearly in the left-right direction and the plurality of holding members 311 arranged side by side in the front-rear direction. It is composed of a holding body 31 and a frame body 32 capable of holding a plurality of holding bodies 31 side by side in the vertical direction, and by arranging them adjacent to the storage 1, misreading can be inspected. As a result, it is possible to inspect misreading by arranging a plurality of identification elements in the left-right direction, the front-back direction, and the up-down direction. That is, it is possible to simultaneously inspect for misreading at a plurality of positions. As a result, it becomes possible to improve the inspection efficiency of misreading. Further, since the detection range can be widened in one inspection, the misreading range can be specified more efficiently.

Further, the holding body 31 is configured so that the position of the holding member 311 in the front-rear direction can be adjusted. As a result, at the time of misreading inspection, the front of the inspection device 3 is arranged so as to face the storage 1, and the front-rear position of the holding member 311 is adjusted, so that the misreading is performed at a position separated from the storage 1 by an arbitrary distance. Multiple inspections can be performed at the same time. As a result, inspection at the inspection position according to the target specifications of the storage 1 becomes possible.

Further, since the plurality of holding bodies 31 are held in the frame body 32 so that the positions in the vertical direction can be adjusted, the inspection range of the misreading inspection can be adjusted in the vertical direction according to the height of the storage 1 and the like. Can be done.

Further, since the holding body 31 is provided with a scale portion 312f in which scales are arranged in the front-rear direction, the inspector can adjust the front-rear position of the holding member 311 by referring to the scale portion 312f. It can be done easily.

Further, the inspection device 3 positions the inspection device 3 by the front end surface of the front frame member 312a, which is an end portion located on the front side of the inspection device 3, abuts on the storage 1, and is arranged on the scale unit 312f. The scale indicates the distance from the front end face. That is, the scale unit 312f displays the distance from the storage 1 in the state where the inspection device 3 is positioned. This will
The distance of the holding member 311 from the storage 1 becomes clear at a glance, and the distance of the RFID tag 10a from the storage 1 can be easily grasped and adjusted.

Further, the inspection device 3 can be easily moved by providing the casters 33. As a result, it is possible to efficiently carry out a wide range of inspections and inspections of a plurality of storage units 1.

In the misreading inspection, the front surface of the inspection device 3 does not necessarily have to face the storage 1. The inspection device 3 may be arranged so that the back surface of the inspection device 3 faces the storage storage 1 at the time of misreading inspection, or either the left or right side of the inspection device 3 faces the storage storage 1. In other words, at the time of inspection, the storage 1 may be positioned so as to be arranged in the front-rear direction with respect to the inspection device 3, or may be positioned so as to be arranged in the left-right direction.

Further, in the misreading inspection, the probe or antenna of the radio wave intensity sensor 40 capable of measuring the radio wave intensity may be attached to the sensor pocket 311a of each holding member 311 to measure the radio wave intensity according to the distance from the storage 1. .. Thereby, the radio field intensity at the sensor pocket 311a, that is, at a position separated from the storage 1 by an arbitrary distance can be measured. Therefore, when misreading is detected, the radio field intensity at that position can be specified.

Further, the RFID tag 10a used for the inspection may store individual position information inside the inspection device 3 in advance, and the determination device 4 outputs the detected position information of the RFID tag 10a to the display device 5. You may. This makes it easier to identify the position of the detected RFID tag 10a.

The holding body 31 and the frame body 32 constituting the inspection device 3 are preferably made of a material having low reflectance of radio waves in the frequency band used for communication between the RFID tag 10a and the RFID reader 10. By doing so, it is possible to reduce erroneous detection and detection omission of the RFID tag 10a due to the inspection device 3 reflecting radio waves. As a material having low reflectance of radio waves, for example, it is desirable to use a resin material such as plastic.

Further, the larger the external dimension of the holding body 31, that is, the length dimension of the outer frame 312 in the left-right front-rear direction, the wider the inspectable range can be widened by one arrangement. That is, it is possible to reduce the time required for misreading and inspecting one storage unit 1. When a misreading inspection is performed using one inspection device 3 according to the present embodiment, the length dimension of the holding member 311 is the longest dimension among the width dimensions of the front, rear, left and right surfaces of the storage 1 to be inspected. It is preferably equal to or slightly larger than that. By doing so, the misreading inspection on the front, rear, left, and right sides of the storage 1 can be performed once for each side.

FIG. 7 is a diagram showing a state when a misreading inspection of a plurality of storages 1a to 1c using the inspection device 3 is viewed from above. In a situation where a plurality of storages 1a to 1c are installed close to each other, another storage 1a may detect the RFID tag 10a housed in the storage 1b, or the RFID tag 10a outside the storage 1 may be detected. There is a possibility that proper inventory control and temperature control may be hindered by the detection of the above by a plurality of storages 1. In FIG. 7, a plurality of storages 1a to 1c accommodating the RFID tag 10a are arranged, and the inspection device 3 is arranged in front of each storage 1. By specifying the position of the RFID tag 10a detected by each storage in this state, it is possible to carry out a misreading inspection assuming a situation in which a plurality of storages are installed close to each other. Further, since the misreading inspection of a plurality of storages can be performed at the same time, for example, the pre-shipment inspection at the mass production stage can be efficiently performed. As a result, it is possible to increase the number of shipments per day.
