In this case, it is possible to determine whether or not the dispensed drugs of each brand are in accordance with the prescription.

  FIG. 1 is a schematic block diagram for explaining a configuration of a medicine inspection system according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes the brand and the number (including the number of drug sheets) for each of a plurality of brands designated by the prescription by scanning the prescription 1a brought to the dispensing pharmacy by the patient and recognizing characters. ) Is recorded on the prescription data recording section 2, and a plurality of brand medicines (PTP sheets 3 a to 3 c for each brand in the example of FIG. 1) dispensed by the pharmacist of the dispensing pharmacy according to the prescription are placed. It is a mounting table. In the first embodiment, when the pharmacist places a plurality of dispensed PTP sheets 3a to 3c on the mounting table 2, the surface on which the barcode is displayed is placed upward. To do.

  In the first embodiment, when there are a plurality of PTP sheets 3a to 3c for each brand, the same brand PTP sheets are gathered together with a rubber band of a predetermined color (an example of a binding tool). Try to bundle. That is, in the first embodiment, when a plurality of PTP sheets of the same brand are bundled, for example, 2 sheets are red, 3 sheets are blue, 4 sheets are green, 5 sheets are purple, and 10 sheets are yellow. In addition, the color of the rubber band corresponding to each number of sheets from 2 to 10 is determined in advance, and when the pharmacist bundles a plurality of PTP sheets of the same brand with the rubber band, the rubber band of the predetermined color is used. Use it and bundle it. In the first embodiment, when the number of PTP sheets of the same brand exceeds 10, the 10 sheets are bundled with yellow rubber bands, and the remaining plural sheets are bundled with the corresponding colored rubber bands. If only one piece is used, no rubber band is used. In the example of FIG. 1, the dispensed plural brands of PTP sheets 3a to 3c arranged on the mounting table 2 are bundled with a red rubber band 4a from the left side of the figure, since there are two PTP sheets 3a. Since 3b is 5 sheets, it is bundled with a purple rubber band 4b, and since the PTP sheet 3c is 1 sheet, no rubber band is used.

  In FIG. 1, reference numeral 5 denotes a camera disposed above the mounting table 2 so that the entire surface of the mounting table 2 can be imaged, and reference numeral 6 denotes a plurality (on the mounting table 2 acquired by the camera 5 ( 1 is an image recording unit for recording images of the PTP sheets 3a to 3c of the respective brands, and 7 is an area (medicine area) where the PTP sheets 3a to 3c of the three brands are present in the image. ) Is a drug region extraction unit for extracting each of the images. The drug region extraction unit 7 cuts out, for example, only a portion having high luminance from the background (image of the floor surface of the mounting table 2) from the entire image including the multiple brands of PTP sheets 3a to 3c on the mounting table 2. The regions (drug regions) of the PTP sheets 3a to 3c are extracted by a known method such as the above.

  In FIG. 1, reference numeral 8 denotes a barcode area extraction unit that extracts an image of a barcode part from each drug area image extracted by the drug area extraction unit 7, and 9 denotes an extraction by the barcode area extraction unit 8. A barcode reading unit 10 that reads barcode information from an image in the barcode area is a barcode dictionary that records combinations of barcode bar lengths and corresponding characters or symbols.

  The barcode area extraction unit 8 extracts, for example, image features and corner detection, edge extraction, matching (change) based on geometrical features of a figure, general barcode size, and the like from the image of each drug region. The barcode portion in each drug region is extracted by a known method such as comparison of. The barcode reading unit 9 obtains, for example, information on the length of the bar and a combination thereof from the extracted image of each barcode part (preferably an image obtained by binarizing the barcode part), and stores the information in the barcode dictionary. The barcode information composed of characters and symbols is read by a known method such as collation with the data recorded in FIG. In the first embodiment, a total of three brands of PTP sheets 3a to 3c having different heights on the upper surfaces on which the respective barcodes are displayed are imaged by a single camera 5 arranged above the PTP sheets 3a to 3c. Therefore, some of the barcodes displayed on the PTP sheets 3a to 3c of the three brands may not be focused and may not be clearly imaged. However, for example, the lens of the camera 5 has a short focal length (deep depth of field), and the camera 5 is at a certain distance (for example, several tens of centimeters or more) from the upper surface of each of the PTP sheets 3a to 3c. If it is arranged at a position distant from the above, it is possible to image each bar code on each upper surface of each of the PTP sheets 3a to 3c with such a definition that all of them can be read.

  Further, in the first embodiment, the barcode reading unit 9 has a function of first determining which of the plurality of barcode standards such as JAN and EAN the barcode to be read is, By referring to the corresponding storage area of the barcode dictionary 10 corresponding to the determined standard, barcode information is read from the barcode area image (the barcode dictionary 10 stores a plurality of storage areas. Each of these storage areas has a barcode dictionary corresponding to a plurality of barcode standards).

  In FIG. 1, reference numeral 11 denotes a binding tool region extraction unit that extracts the rubber band 4 a and 4 b regions from the medicine region images extracted by the medicine region extraction unit 7, and reference numeral 12 denotes the binding tool region extraction unit 11. It is a color information acquisition part which acquires the color information of a binding tool from the image of the performed binding tool area | region. For example, the binding tool region extraction unit 11 removes noise from the image of each drug region and then determines the brightness and density of each pixel (the rubber band reflects a lot of light because the PTP sheet is made of aluminum. Since the image does not reflect much light), the image is binarized by distinguishing between pixels that do not reflect much light and pixels that reflect a lot of light, and pixels that hardly reflect light from this binary image are concentrated. Each region of the rubber bands 4a and 4b is extracted by a method such as taking out a portion that is in the middle of the drug region and in the center in the longitudinal direction. Further, the color information acquisition unit 12 corresponds to each region of the rubber bands 4a and 4b by acquiring RGB data for each pixel constituting each region of the rubber bands 4a and 4b extracted as described above. Get each color information.

  In FIG. 1, reference numeral 13 denotes a bar code information from the bar code reading unit 9, color information from the color information acquisition unit 12, and a relationship between a rubber band color and the number of PTP sheets. Based on the information from the number-of-colors recording unit 14, data of the number of drugs of each brand that has been dispensed (in the example of FIG. 1, the number of PTP sheets 3 a to 3 c of the three brands on the table 2 described above) It is a dispensed drug data acquisition unit that acquires and records. The dispensed medicine data acquisition unit 13 acquires the brand data of each of the PTP sheets 3a to 3c from the barcode information, and the PTP sheets 3a to 3b from the presence / absence of the rubber bands and the color information of the rubber bands 4a and 4b. Each number data of 3c is acquired.

  In FIG. 1, reference numeral 15 denotes dispensed medicine data from the dispensed medicine data acquisition unit 13 (in the example of FIG. 1, the total number of PTP sheets 3 a to 3 c of three brands on the table 2 described above) and the above It is a collation unit that compares and collates each brand and number data of medicines indicated by the prescription from the prescription data recording unit 1 and outputs the collation result to the output unit 16 such as a display.

  In the first embodiment, the mounting table 2 and the camera 5 are housed in a predetermined housing (not shown). The prescription data recording unit 1, the image recording unit 6, the barcode dictionary 10, and the color number recording unit 14 are configured by, for example, a hard disk of a personal computer. In addition, the drug region extraction unit 7, the barcode region extraction unit 8, the barcode reading unit 9, the binding tool region extraction unit 11, the color information acquisition unit 12, the dispensed drug data acquisition unit 13, and the The collation unit 15 is configured and realized by, for example, a personal computer CPU, memory, program, and hard disk.

  As described above, in the first embodiment, the PTP sheets 3a to 3c of the plurality of brands arranged on the mounting table 2 after being dispensed are imaged together, and the images of the PTP sheets 3a to 3c are collected. The drug area of each brand, each barcode area in it is extracted and each barcode information is read, and each rubber band 4a, 4b area is extracted from the images of the PTP sheets 3a-3c, and each PTP sheet is extracted. The presence / absence of the rubber band and the color information of the rubber bands 4a and 4b are acquired, and the brands and the number (sheets) of the PTP sheets 3a to 3c on the mounting table 2 are acquired from the acquired information. Then, the collation unit 15 compares and collates the brand and number of sheets (sheet number) of the PTP sheets 3a to 3c thus obtained with the brand and number of medicines indicated by the prescription, whereby the pharmacist Determine if each brand of dispensed drug and its number is really as prescribed. Therefore, according to the first embodiment, when there are a plurality of PTP sheets of each brand dispensed, the PTP sheets are bundled with rubber bands of a color determined for each number, and then arranged on the mounting table 2 and imaged. This makes it possible to audit whether each brand and number of drugs dispensed by the pharmacist is really compatible with each brand and number of drugs indicated by the prescription. It can be performed efficiently and at low cost.

  Next, a drug inspection system according to Embodiment 2 of the present invention will be described with reference to FIG. Since the basic configuration of the second embodiment is the same as that of the first embodiment, the following description will focus on the differences. In the present Example 2, as shown to Fig.2 (a), the part 21a which mounts the chemical | medical agent of the mounting base 21 which mounts the chemical | medical agent already dispensed is formed of the transparent material. In Example 2, when the dispensed PTP sheets 3a to 3c are placed on the mounting table 21, the side on which the barcode is displayed is the lower side (the transparent portion 21a side). Deploy. Moreover, in the present Example 2, the camera 22 which images each said dispensed chemical | medical agent is arrange | positioned via the predetermined distance from this under the mounting base 21 mentioned above.

  In FIG. 2, reference numeral 20 denotes a housing that houses the mounting table 21 and the camera 22, 20 a denotes a cover that covers the upper opening of the housing 20, and 20 b denotes the cover 20 a with respect to the housing 20. It is the hinge part connected so that opening and closing is possible.

  In the second embodiment, as described above, when the plurality of dispensed PTP sheets 3a to 3c are placed on the transparent portion 21a of the mounting table 21, the side on which the barcode is displayed is downward. These PTP sheets 3a to 3c are imaged by the camera 22 from below (via the transparent portion 21a). Therefore, according to the second embodiment, since all of the barcodes of the PTP sheets 3a to 3c are imaged in the focused state by the camera 22, the barcodes of the PTP sheets 3a to 3c are made high. It is possible to pick up a fine image and to read each barcode with high accuracy. In FIG. 2, the rubber bands for bundling the PTP sheets 3a and 3b are not shown.

  FIG. 2B shows a comparative example of the second embodiment shown in FIG. That is, in FIG. 2B, the PTP sheets 3a to 3c are arranged on the mounting table 25 accommodated in the casing 27 so that the surface on which the barcode is displayed faces upward. 1 shows a configuration in which an image is picked up by a camera 26 from above. When the configuration shown in FIG. 2B is used, all of the PTP sheets 3a to 3c are not imaged in the focused state by the camera 22, so some of the PTP sheets May not be able to image the barcode with high definition. The configuration of the second embodiment shown in FIG. 2A is for solving such a problem.

  Next, a drug inspection system according to Embodiment 3 of the present invention will be described with reference to FIG. Since the basic configuration of the third embodiment is substantially the same as that of the first embodiment, the following description will focus on the differences. In FIG. 3, the same reference numerals are given to the portions common to FIG. In FIG. 3, reference numeral 31 denotes each distance to each PTP sheet 3 a to 3 c that is a medicine of each brand dispensed placed on the table 2 (between the distance measuring sensor 31 and each PTP sheet 3 a to 3 c). A distance measuring sensor 32 for measuring each distance of the PTP sheets 3a to 3c based on distance data from the distance measuring sensor 31 to the PTP sheets 3a to 3c. It is a height information acquisition unit that records the PTP sheets 3a to 3c from the drug region extraction unit 7 in association with the region image data.

  The distance measuring sensor 31 measures the time until reflected light from each upper surface of each of the PTP sheets 3a to 3c returns while scanning spot light from, for example, an infrared LED on the mounting table 2 described above. Thus, a distance image sensor of a TOF (Time-Of-Flight) system that measures each distance to each upper surface of each of the PTP sheets 3a to 3c (image sensor by pulse-modulating infrared rays or the like and irradiating it within the angle of view) Measuring the pulse delay on the side to determine the reciprocal distance to the object). In addition to the above method, the measurement by the distance measuring sensor 31 determines the parallax by pattern matching processing or the like from two camera images, for example, and the PTP sheets 3a to 3c based on the principle of triangulation based on the parallax. It is also possible by a method of measuring each distance to each upper surface of the.

  Further, the height information recording unit 32 acquires the height information of the PTP sheets 3a to 3c from the distances to the upper surfaces of the PTP sheets 3a to 3c, and obtains the height information from the PTP sheets 3a to 3c. Alternatively, it is recorded in association with the area image. Such association is performed, for example, by displaying a mark indicating position coordinates on the entire surface of the mounting table 2 and matching the data of the distance measuring sensor 31 with the data from the camera 5 based on the position coordinates. It is possible by a more known method. For example, if an imaging pixel and a distance measuring pixel are arranged adjacent to each other in the same photodiode portion of a CCD image sensor, an image and distance image data can be simultaneously associated with each other and output. Furthermore, in the system shown in FIG. 3, the “camera 5 and the distance measuring sensor 31” are integrated with “RGB image pixels as well as distance image pixels (Z pixels) adjacent to each RGB pixel. In this case, the RGB image and the distance image of each of the PTP sheets 3a to 3c can be acquired at the same time, and each RGB image sensor It is possible to automatically record the pixels and the distance image pixels in a one-to-one relationship.

  In the third embodiment, the height information of the PTP sheets 3a to 3c acquired in this way, the height of each PTP sheet (bundled with a binding tool) and the number of sheets are recorded in association with each other. Based on the data from the sheet number recording unit 33, the number data of the dispensed PTP sheets 3a to 3c can be obtained (see the dispensed medicine data obtaining unit 13 in FIG. 3). Since the configuration other than the above is the same as that of the first embodiment, the description thereof will be omitted.

  As described above, in the present Example 3, after each of the PTP sheets 3a to 3c of a plurality of brands arranged on the mounting table 2 after being dispensed is imaged together, each distance to each sheet is measured, Each barcode area is extracted from the images of the PTP sheets 3a to 3c to read each barcode information, and the height information of each sheet is acquired from each distance to each of the PTP sheets 3a to 3c. From the acquired information, the brands of the PTP sheets 3a to 3c on the table 2 and the number thereof (sheet number) are acquired. Then, the collation unit 15 compares and collates each brand and the number (sheet number) of the PTP sheets 3a to 3c obtained in this way with each brand and number of the medicine indicated by the prescription. Then, it is determined whether each brand of a plurality of dispensed drugs and the number thereof are really in accordance with the prescription. Therefore, according to the third embodiment, even when there are a plurality of dispensed PTP sheets, they are arranged on the mounting table 2 and imaged, and the height of each sheet is acquired from the sensor information. It is possible to audit whether each brand and number of drugs dispensed by the pharmacist really match with each brand and number of drugs indicated by the prescription, which makes auditing of dispensed drugs extremely efficient. And at low cost.

  Next, a drug inspection system according to Example 4 of the present invention will be described with reference to FIG. Since the basic configuration of the fourth embodiment is the same as that of the third embodiment, the following description will focus on the differences. In the fourth embodiment, as shown in FIG. 4, at least a portion 21a on which the medicine is placed of the placement table 21 on which the dispensed medicine is placed is formed of a transparent material. In the fourth embodiment, when the dispensed PTP sheets 3a to 3c are placed on the placing table 21, the side on which each bar code is displayed faces downward. In the fourth embodiment, the camera 22 that images the dispensed PTP sheets 3a to 3c is disposed below the transparent portion 21a of the mounting table 21 with a predetermined distance therebetween, and A distance measuring sensor 41 for measuring each distance to each of the dispensed PTP sheets 3a to 3c is disposed above the mounting table 21 with a predetermined distance therebetween.

  In the fourth embodiment, as described above, when the PTP sheets 3a to 3c of a plurality of dispensed brands are placed on the mounting table 21, the side on which each barcode is displayed is downward. These PTP sheets 3a-3c are imaged from below (via the transparent portion 21a) by the camera 22. Therefore, according to the fourth embodiment, since all the barcodes of the PTP sheets 3a to 3c are imaged in the focused state by the camera 22, all the barcodes of the PTP sheets 3a to 3c are all captured. Can be picked up with high definition, and the bar code can be read with high accuracy.

  As mentioned above, although each Example of this invention was described, this invention is not limited to what was described as each said Example, A various correction and change are possible. For example, in each of the above Examples 1 to 4, a case has been described in which the present invention is applied to check whether or not a plurality of dispensed PTP sheets of each brand are as prescribed, but the present invention is dispensed The present invention can also be applied to inspect whether medicines other than the PTP sheet (for example, medicines enclosed in bags made of vinyl for each brand) are as prescribed. In each of the above Examples 3 and 4, “the height information of the single medicine sheet 3 c arranged on the mounting table 2, 21 and the rubber band 4 a for each brand arranged on the mounting table 2, 21. , 4 b, each distance information sensor 31 measures each distance from each top surface of the PTP sheets 4 a to 4 c of each brand on the mounting table 21. In the present invention, the height information of each of the PTP sheets 4a to 4c is stored in the mounting table 2, for example. 21. Each side surface of each PTP sheet 4a to 4c on each side (each side surface of a plurality of brand PTP sheets 4a, 4b bundled with rubber bands 4a, 4b, respectively, and one PTP sheet 4c) Side of them) By imaging with a camera installed in the direction (position facing each side surface), and counting the number of vertical pixels on each side surface of each of the PTP sheets 4a to 4c in the image obtained by the imaging, etc. You may make it acquire. Further, in each of the embodiments 3 and 4, as a means for acquiring the height information of each of the PTP sheets 4a to 4c, instead of the distance measuring sensors 31 and 41, an object is scanned with a laser beam. You may make it use the three-dimensional measuring device which acquires the three-dimensional information containing the height information. Further, in each of the embodiments 3 and 4, the camera 5 that acquires the barcode reading image displayed on each PTP sheet and the distance data (distance image) for acquiring the height information of each PTP sheet. The distance measuring sensors 31 and 41 to be acquired are separately provided. In the present invention, the means for acquiring the barcode reading image displayed on each PTP sheet and each PTP sheet are provided. The means for acquiring the distance image for acquiring the height information (that is, the image information acquiring means and the height information acquiring means) are, for example, “pixels for distance images (Z pixels) as well as pixels for RGB images” It is also possible to form a single device such as a “CMOS image sensor that also serves as a distance image sensor”, which is integrated adjacent to each RGB pixel. In the present invention, the “bar code” includes a two-dimensional bar code. In the present invention, the “binding tool” is not limited to a rubber band, and includes, for example, a paper or plastic band seal.
