  In the read information acquisition step S12 illustrated in FIG. 4, the first captured image 31A, which is a picked medicine and is a captured image of a package in which the medicine is packaged, is acquired, and the first captured image 31A includes the first captured image 31A. Read information 31E and second read information 31F are acquired. If the 1st captured image 31A is acquired, it will progress to medicine classification specific process S14.

  In the medicine type specifying step S14, the type of medicine is specified from the first read information 31E acquired in the read information acquiring step S12, and the medicine type information 104 representing the specified type of medicine is acquired. The specification of the medicine type is the same as that of the medicine type specifying unit 102 shown in FIG. When the drug type information 104 is acquired in the drug type specifying step S14 of FIG. 4, the process proceeds to the drug appearance feature acquiring step S16.

  In the medicine appearance feature acquisition step S16, medicine appearance feature information 108 representing the appearance characteristics of the medicine is obtained from the second read information 31F. The acquisition of the drug appearance feature information 108 is the same as that of the drug appearance feature acquisition unit 106 in FIG.

  When the drug appearance feature information 108 is acquired in the drug appearance feature acquisition step S16, the process proceeds to the association processing step S18.

  In the association processing step S18, an association process for associating the medicine type information 104 and the medicine appearance characteristic information 108 is performed. The associating process is the same as that of the associating process unit 110 shown in FIG. 2, and a description thereof is omitted here.

  When the association processing between the medicine type information 104 and the medicine appearance feature information 108 is performed in the association processing step S18 of FIG. 4 and the medicine information 111 is generated, the process proceeds to the registration information confirmation step S20.

  In the registration information confirmation step S20, a registration target that is a medicine in which the medicine type information 104 and the medicine appearance feature information 108 are associated with each other by referring to the medicine information database 114 shown in FIG. It is confirmed whether or not the drug is already registered in the drug information database 114.

  If the drug to be registered, which is the YES determination in the registration information confirmation step S20 shown in FIG. 4, is already registered in the medicine information database 114, the process proceeds to the registration method changing step S22.

  In the registration method changing step S22, the registration method is changed, and the process proceeds to the approval step S24. Details of the registration method change in the registration method change step S22 will be described later.

  In the approval step S24, the registration method changed in the registration method changing step S22 is approved. If the change of the registration method is approved in the approval process S24, the process proceeds to the drug information registration process S26.

  On the other hand, if the registration target drug, which is NO in the registration information confirmation process S20 shown in FIG. 14, is not registered in the drug information database 114, the process proceeds to the drug information registration process S26 via the approval process S24. .

  In the medicine information registration processing step S26, registration of the medicine to be registered in the medicine information database 114 is performed according to the determined registration method.

[Detailed description of drug type identification]
Next, the drug type identification will be described in detail. FIG. 5 is an explanatory diagram for specifying the medicine type. FIG. 5 shows the first surface 36A of the package 36 on which the drug type information 37 is displayed on the first surface 36A of the package 36. Character information is applied to the drug type information 37 shown in FIG.

  The drug type specification is performed in the drug type specifying unit 102 shown in FIG. 2 and the drug type specifying step S14 shown in FIG. 4, and the drug type information 104 is generated.

  The first camera 36 shown in FIG. 1 is used to capture an image of the first surface 36A of the package 36, and a captured image of the first surface 36A of the package 36 is acquired as the first captured image 31A. A display area 37A of the drug type information 37 is extracted from the captured image of the first surface 36A of the package 36.

  For the process of extracting the display area 37A of the drug type information 37 from the captured image of the first surface 36A of the package 36, a known feature area extraction process such as an edge extraction process for detecting a character edge as an edge can be applied. . The description here is omitted.

  Character information is extracted from the display area 37A of the extracted drug type information 37. A known process such as template matching can be applied to the extraction of character information. The description is omitted here.

  The character information extracted in this way is used as drug type information indicating the type of the drug 25 packaged in the package 36. The medicine type information is shown in FIG.

  FIG. 6 is an explanatory diagram of another mode of specifying the medicine type. In FIG. 6, when the display area 37 </ b> B of the drug type information 37 is provided on the second surface 36 </ b> B of the package 36, the second surface 36 </ b> B of the package 36 is illustrated. The second surface 36B of the package 36 is the opposite side of the first surface 36A shown in FIG.

  FIG. 6 shows a case where a plurality of display regions 37B exist on the second surface 36B of the package 36, and the drug type information 37 may be displayed on each of the parts that can be separated. In FIG. 6, only one symbol 37 representing the drug type information is shown.

  When a plurality of display areas 37B are extracted, any one of the plurality of display areas 37B may be a processing target, or all the display areas 37B may be a processing target.

  In FIG. 6, a barcode 37C is displayed as drug type information. The barcode 37C may be obtained by performing barcode reading processing on the image captured by the first camera 31 of FIG. 1 to grasp the contents of the barcode, or by applying a barcode reader instead of the first camera 31 of FIG. Thus, the drug type represented by the barcode may be grasped from the reading data of the barcode reader.

  As shown in FIG. 6, both drug type information 37 consisting of character information and drug type information consisting of a barcode 37C may be displayed. That is, when a plurality of types of drug type information are extracted and the two match, the drug type information 104 is obtained. On the other hand, when the two do not match, the fact that different types of drug type information 37 are acquired is displayed. can do.

  In the present embodiment, text information and a barcode are exemplified as information representing the type of medicine, but information representing the type of medicine may be information that can be extracted from the captured image.

  When acquiring the medicine type information, it is only necessary to obtain a captured image of the surface on which the drug type information 37 is displayed in the first surface 36A or the second surface 36B of the package 36. If the surface on which the drug type information 37 is displayed is known in advance, only the surface on which the drug type information 37 is displayed needs to be imaged, and the surface on which the drug type information 37 is not displayed need not be imaged. Good.

  On the other hand, when the surface on which the drug type information 37 is displayed is not grasped, the first surface 36A and the second surface 36B of the package 36 are imaged. The captured image obtained by imaging the first surface 36A and the second surface 36B of the package 36 in this case is a captured image obtained by imaging at the same time.

  The captured image obtained by imaging at the same time here refers to the imaging of the first surface 36A obtained by imaging the second surface 36B after the imaging of the first surface 36A. An image and a captured image of the second surface 36B are included.

  FIG. 7 is a schematic diagram of the medicine type information 104. The medicine type information 104 shown in FIG. 7 is a case where a plurality of kinds of medicines are picked in the picking operation 12 of FIG. 1, and a medicine when a plurality of medicines picked by the first camera 31 are imaged. Type information.

  The imaging numbers shown in FIG. 7 are reference numbers when there are a plurality of imaging targets. In the packaged medicine inspection device 20 shown in the present embodiment, imaging is performed for each imaging target, that is, for each type of the picked medicine, the type of the medicine is specified for each imaging target, and the type of the picked medicine Each type of medicine is specified.

  In the present embodiment, the drug type identification is shown when only the character information is displayed on the package and when only the barcode is displayed on the package. Although illustration is omitted, when both the character information and the barcode are displayed on the package, either the character information or the barcode may be specified with priority.

  On the other hand, both character information and a barcode may be extracted to specify both the type of medicine grasped from the character information and the kind of medicine grasped from the barcode. In the medicine type information 104 in this aspect, both the medicine type grasped from the character information and the medicine kind grasped from the barcode are associated with the imaging number.

  For the optical reading in the present embodiment, an aspect in which an identification code such as a barcode is read by an optical reading device can be employed.

  The medicine type information having the same imaging number shown in FIG. 7 is the medicine type information specified from the captured image obtained by imaging at the same time.

[Detailed description of drug appearance feature acquisition]
Next, the drug appearance feature acquisition will be described in detail. FIG. 8 is an explanatory diagram of acquisition of a medicine appearance feature. FIG. 8 shows the first surface 36A of the package 36 when the medicine 25 is a tablet. Diffuse light is used for imaging the first surface 36A in order to suppress reflection.

  In the medicine appearance feature acquisition in the present embodiment, the position of the convex portion 70 of the package 36 is specified. Since the convex portion 70 of the package 36 contains the medicine 25, the position of the convex portion 70 is set as the position of the pharmaceutical 25.

  For the extraction of the convex portion 70, a known method such as a feature region extraction process such as edge detection or a shadow detection by oblique illumination can be applied. Therefore, detailed description of the extraction of the convex portion 70 is omitted.

  Then, at the position of the specified medicine 25, medicine appearance feature information representing the appearance characteristics of the medicine 25 is extracted. The drug appearance feature information is shown in FIG. In the present embodiment, a captured image of the medicine 25 is extracted as an appearance feature of the medicine 25. That is, the captured image of the medicine 25 is extracted from the captured image of the first surface 36A of the package 36.

  FIG. 9 is an explanatory diagram of acquiring a drug appearance feature according to another package. FIG. 9 shows the first surface 36A of the package 36 when the medicine 25 is a capsule. Similarly to the case where the medicine 25 shown in FIG. 8 is a tablet, the position of the convex portion 70 of the package 36 is specified, the position of the convex portion 70 is the position of the medicine 25, and the medicine 25 at the specified position of the medicine 25 is used. The captured images are extracted.

  FIG. 10 is a schematic diagram of drug appearance feature information. The medicine appearance feature information 108 shown in FIG. 10 is a case where a plurality of kinds of medicines 25 are picked, similarly to the medicine type information 104 shown in FIG. 7, and a plurality of medicines picked by the first camera 31 are used. 25 is medicine type information when the image is taken. That is, the medicine type information obtained by imaging at the same time.

  The imaging numbers shown in FIG. 10 are reference numbers when there are a plurality of imaging targets, similar to the medicine type information 104 shown in FIG. In this embodiment, imaging is performed for each imaging target, that is, for each type of picked medicine, and appearance characteristic information of the medicine is acquired for each imaging target.

  The appearance feature of imaging number 1 in FIG. 10 is when the medicine 25 shown in FIG. 8 is a tablet. The appearance feature of the imaging number 2 shown in FIG. 10 is a case where the medicine 25 shown in FIG. 9 is a capsule.

  The imaging number in the medicine appearance characteristic information 108 shown in FIG. 10 corresponds to the imaging number in the medicine type information 104 shown in FIG. The drug type information 104 and the drug appearance characteristic information 108 having the same imaging number are drug type information and drug appearance characteristic information obtained by imaging at the same time.

[Detailed description of association]
Next, the association will be described in detail. FIG. 11 is an explanatory diagram of the association process. The association processing unit 110 shown in FIG. 11 associates the medicine type information 104 shown in FIG. 7 obtained by photographing at the same time with the medicine appearance characteristic information 108 shown in FIG.

  That is, using the imaging number in the medicine type information 104 shown in FIG. 7 and the imaging number in the medicine appearance feature information 108 shown in FIG. 10 as key items, the medicine type information 104 shown in FIG. 7 and the medicine appearance shown in FIG. The drug information 111 shown in FIG. 11 is generated by combining the feature information 108.

  The drug information 111 shown in FIG. 11 is registered in the drug information database 114 shown in FIGS. 2 and 3 when the presence / absence of the existing registration is confirmed and there is no existing registration.

[Description of registration method change]
Next, the registration method change will be described in detail.

  The registration method is changed by registering the same type of drug as the drug for which the process of associating the drug type information 104 with the drug appearance feature information 108 is already registered in the drug information database 114 in the registration information confirmation step S20 of FIG. It is processing when there is.

  In the present embodiment, additional registration, average image registration, and change registration are applied as changes in the registration method. Whether additional registration, average image registration, or change registration is performed is pre-registered appearance feature information that is appearance feature information of a medicine that has already been registered, and appearance feature information of a medicine to be registered The difference between the newly acquired appearance image, the registration date and time in the already registered medicine and the registration date and time of the medicine to be registered, or the image quality of the captured image that is the appearance characteristic information in the already registered medicine, It is determined by superiority or inferiority of the image quality of the captured image, which is appearance characteristic information in the drug to be registered.

  The additional registration is a registration method that leaves the previously registered appearance feature information and adds newly obtained new appearance feature information. The change registration is a registration method for registering new appearance feature information instead of the already registered appearance feature information. This is a registration method for registering an average image of already registered appearance feature information and new appearance feature information.

  Note that the determination condition for determining whether or not to change the registration method is not limited to the above example, and can be added, deleted, or changed as appropriate.

  FIG. 12 is a flowchart showing the flow of the registration method change procedure. The flowchart shown in FIG. 12 is a flowchart in the registration method changing step S22 of FIG.

  As shown in FIG. 12, when the registration method change is started, in the appearance feature information evaluation step S100, is the appearance feature information of the medicine to be registered identical to the appearance feature information of the already registered medicine? An evaluation of whether or not is performed.

  In the appearance feature information evaluation step S100, the difference between the newly acquired appearance image and the registered appearance image that is the already registered appearance feature information is extracted, and the number of differences and the degree of difference for each difference are derived. It is determined whether or not a predetermined criterion is exceeded.

  In the appearance feature information evaluation step S100, when the difference between the two exceeds a predetermined reference, in the case of YES determination in the appearance feature information evaluation step S100, it is determined that the two are different.

  If it is determined that they are different in the appearance feature information evaluation step S100, the process proceeds to the registration date evaluation step S102.

  In the registration date evaluation step S102, it is determined whether or not the registration date of the registered medicine is after the date when the design of the registered medicine is changed. That is, it is determined whether or not the difference in appearance feature information is a difference between old and new designs.

  In the registration date evaluation step S102, when the registration date of the registered drug is before the date when the design change of the registered drug is changed, in the case of YES determination of the registration date evaluation step S102, the difference between the two is the old and new designs. Judged to be a difference. In the registration date evaluation process S102, if it is determined that the difference between the two is the difference between the old and new designs, the process proceeds to the additional registration process S104.

  That is, when the appearance feature information registered in the drug information database 114 shown in FIG. 2 is an old design before the design change, the new design is applied to the drug type for which the appearance feature information by the old design is registered. Appearance feature information is additionally registered.

  In the additional registration step S104, appearance feature information is additionally registered for the drug type of the drug to be registered. When the additional registration is performed, a plurality of appearance feature information is registered in the medicine information database 114 shown in FIG. In the additional registration step S104, when the appearance information of the drug to be registered is additionally registered, the image registration method change is terminated.

  On the other hand, in the registration date evaluation step S102, when the registration date of the registered medicine is after the date when the design change of the registered medicine is changed, the difference between the two is as follows. It is judged that there is no difference between the old and new designs. In the registration date evaluation process S102, if it is determined that the difference between the two is not the difference between the old and new designs, the process ends without registering the drug to be registered.

  On the other hand, if it is determined in the appearance feature information evaluation step S100 that the determination is NO and the two are not different, the process proceeds to the image quality evaluation step S106.

  In the image quality evaluation step S106, the image quality of the captured image that is the external feature information of the registration target drug and the captured image that is the external feature information of the registration target are compared. The image quality evaluation may be performed by calculating the image quality evaluation values of the two and comparing the calculated image quality evaluation values.

  In the image quality evaluation step S106, in the image quality evaluation step S106, the difference in quality between the captured image that is the external feature information to be registered and the captured image that is the registered external feature information is within an allowable range. In the case of YES determination, the process proceeds to the average image registration step S108.

  In the average image registration step S <b> 108, an average image is generated by averaging the captured image that is the appearance feature information of the medicine to be registered and the captured image that is the appearance feature information of the registered medicine. The generated average image is registered as appearance feature information of the drug to be registered. In the average image registration step S108, when the average image is registered as appearance feature information for the drug to be registered, the image registration method change is terminated.

  On the other hand, in the image quality evaluation step S106, in the case of NO determination in the image quality evaluation step S106, which is a case where the quality difference between the captured image to be registered and the registered captured image is large, the process proceeds to the image quality comparison step S110. move on.

  In the image quality comparison step S110, the image quality of the captured image of the registration target medicine is compared with the image quality of the captured image of the registered medicine. In the image quality comparison step S110, if the image quality of the captured image to be registered is higher than or the same as the registered image quality, the change registration step Proceed to S112.

  In the change registration step S112, instead of the captured image that is the appearance feature information of the registered medicine, the captured image of the medicine to be registered is newly registered as appearance feature information. When the appearance feature information for the registration target drug is changed and registered in the change registration step S112 in which the registered appearance feature information is replaced with the registration target appearance feature information for the registration target drug, the image registration method change ends. Is done.

  On the other hand, in the image quality comparison step S110, in the case of NO determination in the image quality comparison step S110, which is a case where the image quality of the captured image to be registered is lower than the image quality of the registered captured image, change the registration method. Without changing the image registration method.

  The change in the registration method shown in FIG. 12 is approved by the user in the approval step S24 in FIG.

  In this embodiment, an example in which the registration method change condition is determined in advance and the registration method is automatically changed is illustrated. However, a mode in which the user instructs to change the registration method via the user interface is also possible. is there.

  Further, in the present embodiment, an example of performing any one of additional registration, change registration, and average image registration as a change in the registration method is illustrated, but at least one of additional registration, change registration, and average image registration is illustrated. One embodiment can be adopted.

[Description of effects]
According to the packaged medicine inspection device configured as described above, the picked medicine image is obtained from the picked-up image obtained at the same time, and the medicine type and medicine appearance feature information of the medicine. , And by registering the drug type and drug appearance feature information of the drug in association with each other, when registering the drug information, the external characteristics of the drug for each drug type can be confirmed, Mistakes in registration are prevented.

  In addition, it is possible to register a medicine in a normal dispensing operation, and it is possible to save time and trouble such as collecting information on a medicine to be registered.

  Furthermore, when the medicine to be registered is a medicine that has already been registered, it is possible to maintain certain reliability with respect to the information on the registered medicine by appropriately changing the registration method.

  In the present embodiment, the registration of medicines in a single-packed preparation in which a plurality of medicines are packaged in one bag is exemplified, but the medicine registration shown in the present embodiment can be applied to medicine management in a pharmacy. .

  For example, the present invention can also be applied to inspection of drugs delivered from a pharmaceutical manufacturer, inventory survey of drugs in a pharmacy, or normal dispensing that does not involve single package dispensing.

  In addition, the use of drug information registered in the drug information database shown in the present embodiment can be used not only for dispensing audits in packaged dispensing but also for a list of drugs provided to patients from a pharmacy.

[Application example of first captured image acquisition]
FIG. 13 is an explanatory diagram of an application example of first captured image acquisition. FIG. 13 shows an example in which a stereoscopic imaging camera 31B is used instead of the first camera 31 shown in FIG. A stereoscopic imaging camera is synonymous with terms such as a compound eye camera, a stereo camera, or a 3D camera. Note that 3D is a notation of three dimensions called three-dimensional.

  The stereoscopic imaging camera 31B includes a first imaging unit 31C and a second imaging unit 31D. By imaging the same subject from different viewpoints by the first imaging unit 31C and the second imaging unit 31D, a plurality of viewpoint images having parallax can be obtained. Corresponding points are detected from a set of viewpoint images having parallax, and the distance from the parallax to the object can be obtained.

  As a means for acquiring the first captured image 31A shown in FIG. 1, the stereoscopic imaging camera 31B shown in FIG. 13 is applied to obtain the medicine appearance feature information 108 shown in FIG. The specified convex portion 70 can be easily identified with high accuracy.

  Note that the first captured image 31A illustrated in FIG. 2 may be acquired using either the first imaging unit 31C or the second imaging unit 31D in the stereoscopic imaging camera 31B illustrated in FIG.

[Other application examples of first captured image acquisition]
FIG. 14 is an explanatory diagram of another application example of acquiring a first captured image. FIG. 14 schematically illustrates a case where a plurality of packages 36 are captured in a bundled state and the first captured image 31A illustrated in FIG. 2 is acquired.

  FIG. 14 shows a first side 36A on the front side and a second side on the back side in a state where the package 36 is fan-shaped while the sheet bundle 38 in a state where a plurality of packages 36 are bundled is bound with a rubber band 39. Both sides of 36B are imaged. Fan-shaped refers to a state in which the plurality of packages 36 are expanded in a generally arc shape around one end in the longitudinal direction of the plurality of packages 36 and the packages 36 are shifted in the sheet surface direction. Yes. The pharmacist may spread the sheet bundle 38 in a fan shape as shown in FIG. 14 by his / her hand, or may realize the state shown in FIG. 14 using a mechanical device (not shown).

  As shown in FIG. 14, the packaging 36 is slightly shifted in the sheet surface direction and expanded so that the first surface 36A and the second surface 36B of the packaging 36 can be imaged collectively. Even if the convex portion 70 exists on the first surface 36A and the display area 37A of the drug type information 37 exists on the second surface 36B, the medicine type information is obtained from the first captured image 31A obtained by one imaging. 104 and the drug appearance feature information 108 can both be acquired.

  Also, as shown in FIG. 14, the packaging 36 is slightly shifted in the sheet surface direction so as to be expanded, thereby confirming whether or not different types of sheets are mixed and missing of the number of packaging 36 is measured. It's easy to do.

  Furthermore, the position of the convex part 70 can be specified with high accuracy by using the stereoscopic imaging camera 31B shown in FIG.

[Various forms of drug testing equipment]
<Modification 1>
The medicine testing apparatus 30 is not limited to the form realized by the computer system described with reference to FIG. 1, but can be realized by a wearable terminal using a glasses-type (goggles-type) head-mounted display system. According to this form, it is possible to support dispensing audits using augmented reality (AR).

<Modification 2>
In FIG. 2, a form in which the packaged drug testing device 20 includes the drug information database 114 is shown, but the drug information database 114 may be installed outside the packaged drug testing device 20. For example, the medicine information database 114 may be held in the receipt computer 18 shown in FIG. The medicine information database 114 may be held in another computer (not shown). As shown in FIG. 15, the packaged drug testing apparatus 20 includes a communication 140, and the packaged drug testing apparatus 20 is connected to the network 142. It is also possible to acquire information from the medicine information database 114 via The “external device” that holds the medicine information database 114 may be, for example, a server connected to a network (not shown). The network can be a local area network, a wide area network, or a combination thereof.

<Modification 3>
The means for acquiring the stereoscopic information is not limited to the form using the stereoscopic imaging camera exemplified above, and for example, the following means may be employed.

  That is, a line-shaped illumination light is irradiated from an oblique direction to an object that is a subject, and the reflected light is captured by a camera. If the object has irregularities, the position where the light of the line illumination light hits changes depending on the height of the convex part, so the irradiation position of the line illumination light is moved relative to the object, and the object is scanned, By capturing the reflected light with a camera facing the object, a reflected image reflecting the shape of the convex portion (bulging portion) can be obtained. The image captured in this way is also a form of “captured image”, and the number of packages 36 and the uppermost sheet can be recognized based on “a plurality of captured images” including the captured image.

<Modification 4>
As another means for acquiring three-dimensional information, a form using distance image acquisition by the TOF method is also possible. In the TOF method, by irradiating an object with infrared light and receiving reflected light from the object, distance information to the object can be acquired based on the phase of the received reflected light. . The concept of “imaging” includes optically reading an object with a TOF camera and obtaining image information corresponding to the distance of each position of the object. The TOF system camera is a form of “imaging unit”, and the image information obtained by the TOF system camera is a form of “captured image”. Note that TOF is after omission of Time of Flight representing the optical flight time.

<Modification 5>
The first camera 31 preferably employs means capable of acquiring stereoscopic information, but is not necessarily limited to that capable of acquiring stereoscopic information. Even in the case of a planar image, the positional relationship in the overlapping direction of the medicine sheets can be grasped from the cross relationship between the outer edges.

<Modification 5>
The first camera 31 is not limited to generating still image data, and may generate moving image data. A technique for extracting still image data from moving image data is well known, and image information obtained from moving image data also corresponds to a form of “captured image”.

<Modification 6>
In the above-described embodiment, the example in which the front side and the back side of the sheet bundle 38 are separately imaged by two imaging operations with one first camera 31 has been described. However, the present invention is not limited to this mode. First, an imaging unit that images the first surface 36A that is the front side of the sheet bundle 38 and an imaging unit that images the second surface 36B on the back side of the sheet bundle 38 are provided separately, and both sides are simultaneously imaged. It is also possible to acquire the captured image.

<Modification 7>
In FIG. 14, the example in which the sheet bundle 38 is imaged in a fan-shaped state has been described. However, the state of the sheet bundle at the time of imaging is not limited to the example described in FIG. 14. In carrying out the invention, instead of taking a separate image of each of the medicine sheets in the sheet bundle, the imaging is performed in the state of the sheet bundle, and the character string and the identification code written on the package of the medicine sheet That at least one of the identification information can be extracted from the captured image and that at least a part of each of all the drug sheets is imaged in order to correctly count the number of all the drug sheets included in the sheet bundle. Required. As long as this condition is satisfied, the specific state of the sheet bundle at the time of imaging can be changed as appropriate.

  For example, it may be possible to image at least a part of all the packages 36 without expanding the sheet bundle 38. In carrying out the invention, it is not always necessary to take an image in a state where the sheet bundle is expanded. However, for more accurate inspection, it is preferable to acquire a plurality of captured images by changing the shooting direction, and in particular, imaging with the overlapping position of the package 36 being shifted as shown in FIG. Is preferred.

<Modification 8>
In the above-described embodiment, the drug registration in the packaged drug testing device 20 has been described. However, the registration unit 20A illustrated in FIG. 2 can be grasped as one form of the drug registration device. Further, the processing function of the registration unit 20A is not limited to a form realized by one computer, and the processing function is shared by a plurality of computers, and the processing function of the registration unit 20A is realized by a combination of a plurality of computers. Forms are also possible.
