The first sensor 30 detects that none of the detected parts 51B to 55B is between the first light projecting part 32 and the first light receiving part 34.

These detection results are input to the determination section 66 from the first sensor 30 (first light receiving section 34) and the second sensor 40 (second light receiving section 44). Based on the input detection results, the determining unit 66 determines that the contact portions 51A to 55A of the arms 51 to 55 are all in contact with the flat back surface of the drug container 10, and therefore the drug container 10 has a flat back surface. It is determined that the image is placed at the top.

FIG. 7 is a perspective view showing the discrimination of the surface of the medicine container 10 by the discrimination device 20. The drug container 10 shown in FIG. 7 is different from FIG. 3 in that it is arranged so that the drug container sheet 11 faces upward and the lid sheet 12 faces downward. Therefore, the medicine container 10 is arranged so that the uneven surface faces upward and the flat back surface faces downward.

The contact portions 51A to 55A of the arms 51 to 55 shown in FIG. 7 are all in contact with the drug storage sheet 11 of the drug container 10, and are in contact with the uneven surface of the drug container 10. In the contact unit 50 shown in FIG. 7, the contact portion 52A of the arm 52, the contact portion 53A of the arm 53, and the contact portion 54A of the arm 54 are in contact with the flat portion 11f of the drug storage sheet 11. The contact portion 51A of the arm 51 and the contact portion 55A of the arm 55 are in contact with the storage portion 11p of the medicine storage sheet 11.

FIG. 8 is a schematic diagram showing the arrangement of the first sensor 30, the second sensor 40, and the detected parts 51B to 55B, which corresponds to the arrangement of the contact unit 50 shown in FIG.

As shown in FIGS. 7 and 8, the detected part 51B of the arm 51 and the detected part 55B of the arm 55 are located between the second light projecting part 42 and the second light receiving part 44 of the second sensor 40. It is located in The detected parts 51B and 55B are arranged so as to block the light emitted from the second light projecting part 42 and prevent the second light receiving part 44 from receiving the light emitted by the second light projecting part 42.

The detected part 52B of the arm 52, the detected part 53B of the arm 53, and the detected part 54B of the arm 54 are arranged between the first light projecting part 32 and the first light receiving part 34 of the first sensor 30. ing. The detected parts 52B, 53B, and 54B are arranged so as to block the light emitted from the first light projector 32 so that the light emitted by the first light projector 32 is not received by the first light receiver 34.

In the arrangement of the contact unit 50 shown in FIGS. 7 and 8, the first sensor 30 has any of the detected parts 51B to 55B between the first light projecting part 32 and the first light receiving part 34. Detect things. The second sensor 40 also detects that any of the detected parts 51B to 55B is present between the second light projecting part 42 and the second light receiving part 44.

These detection results are input to the determination section 66 from the first sensor 30 (first light receiving section 34) and the second sensor 40 (second light receiving section 44). Based on the input detection results, the determining unit 66 determines that at least one of the contact portions 51A to 55A of each arm 51 to 55 is in contact with a convex portion on the surface of the drug container 10, and that the contact portion 51A .about.55A is in contact with the concave portion of the surface of the drug container 10, and therefore, it is determined that the drug container 10 is arranged with the uneven surface facing upward.

As described above, in the discrimination device 20 of the embodiment, the discrimination unit 66 uses the results of the detection of the detected parts 51B to 55B by the first sensor 30 and the results of the detection of the detected parts 51B to 55B by the second sensor 40. Based on the detected results, the front and back sides of the medicine container 10 are determined. The contact parts 51A to 55A come into contact with the drug container 10, and the detected parts 51B to 55B, which are integrated with the contact parts 51A to 55A, change their arrangement according to the positions of the contact parts 51A to 55A. The placement is sensed by the first sensor 30 and/or the second sensor 40. Therefore, the front and back sides of the medicine container 10 can be determined with a simple configuration.

As shown in FIGS. 3 and 4, the contact unit 50 includes a plurality of arms 51 to 55, each of which has a contact portion and a detected portion. The contact portions 51A to 55A of each of the plurality of arms 51 to 55 contact the drug container 10, and the detected portions 51B to 55B of each of the plurality of arms 51 to 55 are arranged according to the positions of the contact portions 51A to 55A. is detected by the first sensor 30 and/or the second sensor 40. Therefore, the front and back sides of the drug container 10 can be determined with a simple configuration.

As shown in FIGS. 3 and 6, the determination unit 66 is configured such that one of the first sensor 30 and the second sensor 40 detects the detected parts 51B to 55B, and the other detects the detected parts 51B to 55B. Based on the detection result in which 55B is not detected, the back surface of the medicine container 10 is determined. As shown in FIGS. 7 and 8, the determination unit 66 determines whether the medicine is contained or not, based on the detection result that both the first sensor 30 and the second sensor 40 detect one of the detected parts 51B to 55B. The surface of the body 10 is determined.

When the contact portions 51A to 55A come into contact with the surface of the drug container 10 having an uneven shape, some of the plurality of detected portions 51B to 55B are detected by the first sensor 30, and the remaining detected portions 51B to 55A are detected by the first sensor 30. 55B is detected by the second sensor 40. When the contact parts 51A to 55A come into contact with the back surface of the flat medicine container 10, all of the plurality of detected parts 51B to 55B are detected by only one of the first sensor 30 and the second sensor 40. Detected. Based on such detection results, the determining unit 66 can reliably determine whether the medicine container 10 is front or back.

As shown in FIG. 4, the plurality of arms 51 to 55 are arranged side by side. The distance between adjacent arms 51-55 in contact portions 51A-55A is larger than the distance between adjacent arms 51-55 in detected portions 51B-55B.

In order to accurately determine the surface of the drug accommodating body 10 having an uneven shape, at least one of the plurality of arms 51 to 55 should be in contact with the accommodating portion 11p of the drug accommodating sheet 11, and at least one should be in contact with the accommodating portion 11p of the drug accommodating sheet 11. It is required to contact the flat portion 11f. By widening the interval between the adjacent arms 51 to 55 in the contact parts 51A to 55A and increasing the overall width of the contact parts 51A to 55A, contact parts are provided in both the storage part 11p and the flat part 11f of the drug storage sheet 11. 51A to 55A can be brought into reliable contact.

By keeping the distance between the adjacent arms 51 to 55 in the detected parts 51B to 55B small, the casing 21 of the discrimination device 20 can be made smaller. Even when the first sensor 30 and the second sensor 40 are commercially available photoelectric sensors in which the light emitting part and the light receiving part are integrated, the detected part 51B to 55B can be reliably arranged between the light projecting section and the light receiving section.

As shown in FIGS. 6 and 8, the first sensor 30 and the second sensor 40 are photoelectric sensors each having a light projecting section that emits light and a light receiving section that receives the light. Using a commercially available photoelectric sensor, it is possible to determine the front and back sides of the drug container 10 with an inexpensive configuration.

Since the detected parts 51B to 55B are non-light-transmissive, the detected parts 51B to 55B arranged between the light receiving part and the light projecting part can be reliably detected by the photoelectric sensor.

In the embodiments so far, an example has been described in which each of the arms 51 to 55 is swingable about the shaft portion 58. In each of the arms 51 to 55, the detected parts 51B to 55B change the arrangement according to the position of the contact parts 51A to 55A that contact the medicine container 10, so that the first sensor 30 and/or the second sensor 40 can be detected. Any configuration may be used as long as it can detect the parts 51B to 55B. For example, each of the arms 51 to 55 may be slidable in the vertical direction.

In the embodiment, an example has been described in which the detected parts 51B to 55B, which are detected by the first sensor 30 and/or the second sensor 40, are provided at the ends of the arms 51 to 55. The first sensor 30 and the second sensor 40 may detect the movement of an actuator that is linked to the movement of the arms 51 to 55, and in this case, the overall size of the discrimination device 20 can be reduced.

In the embodiment, an example in which the first sensor 30 and the second sensor 40 are photoelectric sensors has been described. The first sensor 30 and the second sensor 40 may be other types of sensors. For example, the first sensor 30 and the second sensor 40 may be contact switches.

In the embodiment, an example in which the contact unit 50 has a plurality of arms 51 to 55 has been described. Contact unit 50 does not necessarily have to have multiple arms. For example, the drive unit (FIG. 5) may be used to move the drug container 10 not only in the direction of the arrows shown in FIGS. After the arm is brought into contact with the drug container 10 and detected by the sensor, the drug container 10 is moved in the width direction and detected by the sensor again, and it is determined whether the detection result of the sensor changes. do. In this way, the contact unit 50 having one arm can determine whether the medicine container 10 is front or back.

The discrimination device 20 described in the embodiment may be used in combination with other devices. For example, the discriminating device 20 of the embodiment is provided in a take-out device for taking out the drug container 10 of a drug dispensing device that dispenses the drug 1 according to a prescription, so that when taking out the drug container 10, the front and back sides of the drug container 10 are It may also be possible to determine.
