Description

[Technical field]

[0001] The present invention relates to a drug size measuring device for simple tabletop use. [Background technology]

[0002] 2. Description of the Related Art In a medicine packaging machine that individually dispenses medicines, particularly solid tablets, a configuration is known in which a cassette equipped with rotating blades is used to dispense the tablets one by one (see, for example, Patent Document 1, etc.). Also, an alignment-supply type medicine feeder that conveys tablets or the like of the same shape while aligning them in a line has also been put to practical use (see, for example, Patent Document 2, etc.). When using such a medicine packaging machine or medicine feeder, it is known that tablets can be moved more efficiently by changing the division of the rotating blades and the position of the regulating members that regulate the flow path of the medicine feeder to suit the dimensions of each tablet. Therefore, configurations are also known in which the medicine packaging machine body is equipped with a regulating member that changes the position of the regulating member depending on the shape and dimensions of the placed tablet, and a measuring unit that measures the dimensions of the placed tablet (see, for example, Patent Documents 3 to 5, etc.). However, tablets come in a variety of shapes, such as an oval sphere or a cylinder with a bulging base, and if the definitions of length, width, and depth, or the measurement position, are different, the resulting tablet dimensions will also change.

[0003] In addition, when there are many types of tablets to be measured, the length, width, and depth must be measured for each type of tablet. Therefore, a mechanism for measuring the dimensions of such tablets easily and quickly has been required. [Prior art documents] [Patent documents]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings described below, each direction will be described according to a three-axis orthogonal coordinate system of XYZ as shown in the drawings, but the present invention is not limited to such a configuration.

[0010] 1 shows a medicine dimension measuring device 100 connected to a medicine packaging machine 200 as a first embodiment of the present invention. Note that the form of the medicine packaging machine is not limited to this configuration, and may be one equipped with only a normal medicine cassette 211, or the medicine dimension measuring device 100 may be attached to medicine packaging machines 200 of various other forms.

[0011] The medicine packaging machine 200 is a device that may be used alone or in combination with a plurality of other machines connected to a dispensing server 500 via a network such as a LAN. The drug packaging machine 200 is a device in which the control device 250 controls the operation of the drug cassettes 211 stored inside the drug packaging machine 200, the drug feeder 240, and the packaging section 230 in accordance with dispensing instructions received from the dispensing server 500, thereby sequentially discharging the appropriate drugs from each drug cassette 211 and packaging the drugs in single packets. In addition, in this embodiment, the term "drug" is used simply, and this term may include powdered medicine, liquid medicine, etc., but due to their characteristics, the drug cassette 211 and the drug dimension measuring device 100 described below mainly handle solid tablets. However, the drug feeder 240 may handle so-called solid tablets divided into multiple pieces, and the drug dimension measuring device 100 may also be used to measure the dimensions of such pieces, so the term "drug" is used.

[0012] The dispensing server 500 is capable of sending and receiving data with the higher-level prescription ordering system 400 and the lower-level drug packaging machine 200, and can receive and store prescription data from the prescription ordering system 400, and issue dispensing instructions to the drug packaging machine 200 and other drug packaging machines not shown based on the prescription data. The dispensing server 500 also holds data on the operating state of the medicine packing machine 200 as packing machine status 501, and also holds a medicine master 502 in which known medicine information relating to various medicines is registered in advance. When the medicine packaging machine 200 detects that the medicine cassette 211 has become empty and medicine cannot be discharged, it transmits a shortage occurrence notification to the medicine dispensing server 500. Furthermore, each medicine cassette 211 is assigned with identification information, and when the correspondence between the identification information and the medicine cassette 211 is registered in the control device 250, it is transferred to the medicine dispensing server 500 and registered in the medicine master 502. With this configuration, the dispensing server 500 is able to select a drug packaging machine 200 having an appropriate drug cassette 211 according to the prescription data from among the multiple drug packaging machines 200 connected to it, and issue a dispensing instruction.

[0013] The medicine packaging machine 200 is equipped with a plurality of medicine storage cabinets 210 in the upper section of the housing 201, which can be individually withdrawn, and inside each medicine storage cabinet 210, pairs of medicine cassettes 211 and base parts 212 are arranged vertically and horizontally.

[0014] The drug cassette 211 is detachable and contains a large number of drugs 5 of any one of various types of drugs, and can be discharged one tablet at a time in response to an instruction from the control device 250. The base portion 212 is a fixing portion to which the drug cassettes 211 can be attached and detached one by one, and the drug cassettes 211 mounted on the base portion 212 can be driven to discharge the drugs 5. The medicine 5 discharged from the medicine cassette 211 falls through a medicine fall path 220 provided inside the medicine storage 210 and reaches the packaging section 230.

[0015] In addition to the medicine cassettes 211 linked to such identification information, the medicine packaging machine 200 also has an arrangement shelf 260 equipped with medicine feeders 240 as general-purpose medicine feeders that can be used for various types of medicine. The arrangement shelf 260 has a handle 261 on the front surface so that it can be pulled out, and the arrangement shelf 260 has four medicine feeders 240 arranged in the Z direction, which is the depth direction. A workbench 262 is provided on the front side of the arrangement shelf 260 and the drug storage cabinet 210, and can be used as a stand by pulling it down towards the front, and can also be used as a stand for the drug dimension measuring device 100, drug containers, etc., which will be described later.

[0016] The configurations of the drug cassette 211, packaging section 230, drug drop path 220, etc. are similar to those of conventional tablet packaging machines, and for example, a tablet packaging machine of a form other than that described in this embodiment may be used. The overall component arrangement, etc., is substantially the same as that of the products already described, so detailed explanation will be omitted. In addition, in the drug packaging machine 200, the so-called packaging operation in which the drug 5 is discharged using these drug cassettes 211, packaging section 230, and drug drop path 220 and packaged in packaging paper as a single or multiple units is similar to the configuration described in, for example, Patent Documents 1 and 2, and therefore a description thereof will be omitted as appropriate.

[0017] As shown in Fig. 3, the drug feeder 240 is a double rotation type feeder in which a container part and a lower structure 214 are integrally combined and mounted on the drug packaging machine 200, and is driven by a drive mechanism 213 of the lower structure 214. The lower structure 214 may have a different shape from or the same shape as the base part 212 corresponding to the drug cassette 211, and in either case, the drug feeder 240 is integrated with the base part and the whole is fixedly installed at any part of the drug storage cabinet 210 or the drug packaging machine 200. In this embodiment, only an aspect in which the drug feeder 240 is integrated with the lower structure 214 serving as the base is shown, but the present invention is not limited to such a configuration, and may be configured to be detachable from the base part 212 like the drug cassette 211, for example.

[0018] FIG. 3 shows a schematic cross section of the medicine feeder 240, and FIG. 4 shows the main structure of the medicine feeder 240 with the transparent top cover removed. The drug feeder 240 comprises a peripheral wall 241 located at the upper part and having a hollow central portion carved out in a circular shape, an annular rotor 242 installed with its upper end loosely fitted into the hollow of the peripheral wall 241 or installed directly below the hollow of the peripheral wall 241, an inclined rotor 243 installed within the hollow of the annular rotor 242, a support mechanism 40 that supports both the inner inclined rotor 243 and the outer annular rotor 242 so that they can rotate about their axes, a drive mechanism 213 that drives the rotation of these, and a sorting section 60 and a regulating mechanism 70 provided on the upper side of the peripheral wall 241.

[0019] The support mechanism 40 keeps the annular rotor 242 in a state where it can rotate about a predetermined axis, in this embodiment, a straight line O1, and keeps the inclined rotor 243 in a state where it can rotate about an inclined line O2 inclined from the straight line O1. The straight line O1 may be vertical, but in this embodiment, it is inclined by, for example, about 3.5° so as not to impair the drug delivery function, although this is not shown. The inner inclined rotor 243 and the outer annular rotor 242 form a rotating container of the double rotation type drug feeder by having the inclined rotor 243 block the hollow space of the annular rotor 242 with a small gap that does not allow the drug 5 to pass through but allows rotation. When the inclined rotor 243 is placed inside the annular rotor 242, it is preferable that the inclined rotor 243 is positioned so that at least a portion of its outer periphery is higher than the upper surface of the annular rotor 242, which is the upper end peripheral portion 245, as described below. With this configuration, the drug 5 placed inside the rotating container is scooped up by the inclined rotor 243 and moved to the upper end peripheral portion 245, as described below.

[0020] The inclined rotor 243 transports the drugs 5 from the peripheral portion 244 of the inclined rotor 243 to the upper peripheral portion 245 of the annular rotor 242 by lifting through rotation and sorting by the sorting section 60, and then aligns the drugs 5 on the upper peripheral portion 245 by horizontal transport through rotation of the annular rotor 242 as shown in Figure 3 and the alignment function of the regulating mechanism 70, while transporting them to the drop discharge port 247.

[0021] As shown in Figures 4 and 5, in this embodiment, the sorting section 60 includes a first sorting member 610 arranged upstream of the regulating mechanism 70 in the drug transport path of the upper end peripheral portion 245 of the annular rotating body 242, and a second sorting member 620 arranged in a position parallel to the regulating mechanism 70 in the drug transport path. Both the first sorting member 610 and the second sorting member 620 are attached via a support member 611 to a peripheral wall 241 which is a plate member including the discharge guide 246 and which supports the restriction mechanism 70 .

[0022] In other words, the sorting section 60 comprises a support member 611 whose vertical position can be adjusted using a screw mechanism, a first sorting member 610 attached to a portion of the support member 611 on the upstream side of the conveying direction and moves up and down accompanying the support member 611, and a second sorting member 620 attached to a portion of the support member 611 on the downstream side of the conveying direction and moves up and down accompanying the support member 611. With this configuration, the sorting section 60 is capable of automatically adjusting the lower end positions of the first sorting member 610 and the second sorting member 620 together up and down by driving the motor from the control device 250 to rotate the screw mechanism and raise and lower the support member 611. In this embodiment, the first sorting member 610 is a chain-like structure made by loosely connecting multiple front-stage hanging objects 612 (three spheres in the figure), and can be easily and inexpensively embodied if a commercially available ball chain or the like is sufficient. In the first sorting member 610, three front-stage hanging objects 612 hang down side by side from the support member 611 above the drug transport path at the upper end peripheral portion 245, and the vertical positions of the front-stage hanging objects 612 are usually adjusted so that the lower ends of the front-stage hanging objects 612 are slightly higher than the height of the drugs.

[0023] The second sorting member 620 has a middle section hanging member 622 and a rear section hanging member 632 that are attached to a portion near the tip of the support member 611 and move up and down together with the support member 621 . The middle stage hanging material 622 and the rear stage hanging material 632 are both made up of multiple spherical bodies loosely connected to form a chain, similar to the first sorting member 610, but compared to the front stage hanging material 612, the spherical bodies are smaller in size and the number of connected bodies has increased. The diameter of the spherical bodies may be different between middle hanging object 622 and rear hanging object 632, and the number of connected bodies may also be different. Also, the shape is not limited to a spherical shape. When the sorting section 60 comes into contact with the medicine 5 in the medicine transport path, it gently pushes the medicine 5 by a reaction force, thereby preventing the medicines 5 from piling up.

[0024] As shown in FIG. 5, the regulating mechanism 70 comprises a first regulating member 71 installed further ahead of the sorting section 60 based on the rotational direction of the upper end peripheral portion 245 of the annular rotating body 242, a second regulating member 72 installed further ahead of the first regulating member 71, a link mechanism 73 connected to both the first regulating member 71 and the second regulating member 72 via a pin-shaped rotation-permitting shaft member or the like, and a mold storage area 74 capable of containing the drug 5. Both the first regulating member 71 and the second regulating member 72 have their oscillating centers located on the peripheral wall 241 side and their oscillating ends located above the upper end peripheral portion 245 of the annular rotating body 242, thereby narrowing the width of the drug transport path above the upper end peripheral portion 245 from the outer periphery side. At least one of the multiple wall surfaces constituting the mold storage area 74 can operate in cooperation with the link mechanism 73, and by manually or electrically moving the movable wall 74a, the dimensions of the sample drug 5a of the drugs 5 placed in the mold storage area 74 can be made to match the spacing between the side walls of the mold storage area 74. With this configuration, the regulating mechanism 70 can be operated in conjunction with the width of the sample drug 5a placed in the mold storage area 74.

[0025] The first regulating member 71 and the second regulating member 72 swing simultaneously and in the same manner in response to the longitudinal movement of the link mechanism 73, so that the adjustment amount of the narrowing of the width of the drug transport path is linked to the width of the sample drug 5a placed on the mold storage area 74. Specifically, when the sample drug 5a is placed in the mold storage area 74 and the link mechanism 73 is moved, the link mechanism 73 advances in the longitudinal direction of the mold storage area 74 and stops when its tip comes into contact with the sample drug 5a. Since the swinging end of the first restricting member 71 and the swinging end of the second restricting member 72 are connected by the link mechanism 73, the swinging end of each of the swinging ends narrows the drug transport path width above the upper peripheral portion 245 to the width of one drug, following the size of the sample drug 5a. In this way, the mold storage area 74 and the link mechanism 73 function as a measuring mechanism for measuring the dimensions of a predetermined position of the sample drug 5a placed on the mold storage area 74. The "predetermined position" may be, for example, the diameter, width, length, thickness, etc. of the sample drug 5a, and when the sample drug 5a is a so-called circular tablet, the diameter is preferable. Since the operator can determine this position when placing the sample drug 5a on the mold storage area 74, it is preferable for the operator to set it to the most appropriate position based on the shape of the drug 5 to be transported on the upper end peripheral portion 245. In addition, the operator may operate the touch panel 251 to register the measurement results of the sample drug 5a placed in the mold storage area 74 of the drug feeder 240 in the drug master 502 together with the measurement positions at which the dimensions were measured, such as the major axis and minor axis, after selecting the shape of the tablet, for example. The manner of registration in the drug master 502 will be described later.

[0026] Further, downstream of the restriction mechanism 70 in the rotation direction of the annular rotor 242, the peripheral wall 241 is formed with a drop discharge port 247 that penetrates vertically.

[0027] The medicines 5 that have fallen from the drop discharge port 247 move to the packaging section 230 via the medicine drop path 220 shown in FIG. 1, and are packaged in a single or multiple bundles in packaging paper.

[0028] As described above, when sequentially discharging the drugs 5 using the drug feeder 240, it is known that the accuracy of transportation is improved by knowing the dimensions of the drug 5, such as by adjusting the drug width using the regulating mechanism 70 and adjusting the specified height using the sorting section 60. Considering the versatility of using the drug feeder 240, placing the sample drug 5a on the mold storage area 74 is the most reliable method, but there is an issue that manually placing the sample drug 5a on the mold storage area 74 is time-consuming, and there has also been a demand to automate this operation as well.

[0029] On the other hand, the operation control of the restriction mechanism 70 and the sorting unit 60 itself can be easily controlled by electronic control as long as the dimensions of the medicine 5 can be shared. Therefore, there has been a demand for a mechanism that can easily measure the dimensions of the medicine 5 and share them with the medicine packaging machine 200. In addition, when the drug feeder 240 is used successively for different drugs, the first drug 5 is sequentially discharged by the drug feeder 240, while the dimensions of the next drug 5' to be used are measured separately without using the mold storage area 74, thereby reducing the effort required to replace the sample drug 5a and improving work efficiency.

[0030] In this embodiment, therefore, a medicine size measuring device 100 as shown in FIG. 6 is attached to a medicine packaging machine 200, thereby enabling the size of the medicine 5 to be measured easily and quickly.

[0031] The drug dimension measuring device 100 is a dimension measuring instrument that can be operated with one hand and is connected to the USB terminal of the drug packaging machine 200, and has a main body 10, a sliding member 20 that can slide relative to the main body 10, and a gripping portion 30 that makes it easier for the operator to support the drug dimension measuring device 100.

[0032] In addition, on the side of the main body 10, there are provided a measurement position selection button 31 labeled SELECT, which is a measurement position selection means that allows the operator to select the measurement position information of the drug 5, and a send button 34 labeled MEASURE, and on the upper surface of the side wall 13, there are display LEDs 41, 42, 43 that display how many times the measurement position selection button 31 has been pressed and which measurement position has been selected. When the measurement position selection button 31 is pressed once, the display LED 41 lights up, when the measurement position selection button 31 is pressed twice, the display LED 42 lights up, and when the measurement position selection button 31 is pressed three times, the display LED 43 lights up. When the measurement position selection button 31 is pressed four times, the display LED 41 lights up again. In this manner, only one display LED lights up at the same time, and when the measurement position selection button 31 is pressed repeatedly, the display LED corresponding to the number of times it is pressed lights up. With this configuration, the operator can select at which measurement position of the dimensions of the drug 5 to measure, depending on the number of times the measurement position selection button 31 is pressed. In addition, the result selected by the measurement position selection button 31 can be visually confirmed by the operator by the display LEDs 41, 42, and 43.

[0033] The gripping portion 30 is a cover-like covering having a rounded upper surface and a convex hemispherical curved surface, and the main body 10, including the gripping portion 30, has a shape similar to that of a mouse used in a personal computer. The grip portion 30 allows an operator to easily hold the drug size measuring device 100 by gripping it with one hand. 7 and 8, the main body 10 has a mounting plate 11 for mounting the drug 5 on the upper surface, three side walls 12, 13, and 14 standing perpendicular to the mounting plate 11, and a spring 15, which is a biasing member on the back side of the mounting plate 11 and has one end connected to the main body 10 and the other end connected to a spring receiving portion 22 of the slide member 20. Note that in order to show the positional relationship with the spring 15 and the control portion 16 described later, parts that are usually covered and cannot be seen are also shown in FIG.

[0034] As shown in Figure 8, when a drug 5 is placed on the drug dimension measuring device 100, a magnet 19 for attaching the drug dimension measuring device 100 to any position on the housing 201 of the drug packaging machine 200 is attached by being inserted into the main body 10 on the rear or back side. With this configuration, for example as shown in Figure 1, the drug dimension measuring device 100 can be attached to any position on the housing 201 using a magnet 19, so there is no need to provide a special space in the drug packaging machine 200 to install the drug dimension measuring device 100, and it can be easily attached, detached, and carried.

[0035] The spring 15 biases the slide member 20 in the direction A toward the side wall 12 of the main body 10, and when no force is applied to the slide member 20, the measurement surface 20a, which is the end on the A direction side, is supported in such a manner that it abuts against the reference surface 12a, which is the inner wall surface of the side wall 12. In this manner, in this embodiment, both sides of the side wall 12 are surrounded by the side walls 13 and 14 so as to hold the slide member 20 along the A direction. With this structure, the slide member 20 is held so as to be slidable only in the ±A direction. In normal use, the drug dimension measuring device 100 is placed so that the mounting plate 11 is parallel to the XZ plane, so that the A direction is equal to the Z direction, but this is not limited to this configuration. In other words, in this embodiment, the surface facing the slide member 20 constitutes the reference surface 12a, and the area surrounded by the side surfaces of the three side walls 12, 13, and 14 rising from the mounting plate 11 and the wall surface of the slide member 20 is the mounting position for the drug 5. The drug dimension measuring device 100 is a measuring means for measuring the length of each part of the drug 5 mounted at such a mounting position.

[0036] A control unit 16, which is an electronic circuit board, is attached to the back side of the mounting plate 11 of the main body 10, as shown in FIGS. A gap 17 is provided on the control unit 16 so that the spring 15 and a spring support 22 described later do not interfere with the control unit 16, and a linear variable resistor 18 is provided along the A direction. The variable resistor 18 is provided with a slide volume 18a, and the resistance value varies depending on the position of the slide volume 18a. The control unit 16 is also provided with a transmission button 34 and a measurement position selection button 31 as electrical contact type switches, and when the operator presses these buttons, the control unit 16 recognizes them as electrical signals.

[0037] 10(a) to 10(f), the sliding member 20 is provided with an opening 21, which is a circular depression that is opened so that an operator can easily hook a finger or the like thereon and pull it in toward the -A direction, which is the opposite side to the biasing direction of the spring 15. The center of the opening 21 is preferably located approximately on the center line of the sliding member 20, and the size of the opening 21 is preferably about 50% of the width of the sliding member 20 so that the operator can easily pull it in toward the grip part 30 with a finger. A spring support portion 22, which is a member to which the other end of the spring 15 is connected, is fixed on the back side of the slide member 20, and a protrusion portion 23, which is a position detection convex portion that engages with the slide volume 18a and moves the slide volume 18a in synchronization with the position of the slide member 20, is also formed.

[0038] Now, the operation of such a drug size measuring device 100 when it is used will be described. As an example, a method of editing master information of medicines recorded in control device 250 or medicine master 502 by operating medicine packaging machine 200 using touch panel 251 will be described here. Prior to operating drug dimension measuring device 100, the operator uses touch panel 251 to select the drug for which dimension information is to be registered from among the drug identification information registered in control device 250 in drug packaging machine 200 or drug master 502. 11 is a diagram illustrating a part of information registered in the drug master 502 for, for example, drug 5. In the drug master 502, in addition to identification information such as the type of drug 5, product name, and YJ code, whether the drug cassette 211 or the drug feeder 240 is used, the drug shape, the drug size, and the like are recorded. Conventionally, an operator manually inputs the dimensions L1, L2, and L3 as drug sizes in the drug master 502. However, in this embodiment, the drug selected in the drug master 502 can be easily input using the drug dimension measuring device 100.

[0039] As already described, the medicine dimension measuring apparatus 100 is a portable device for dimension measurement that is connected to a USB terminal of the medicine packaging machine 200 and is capable of exchanging data. First, as shown in FIG. 12(a), the operator places his / her finger on the opening 21 and pulls the slide member 20 in the -A direction to create a space between the reference surface 12a and the measurement surface 20a, which is the tip surface of the slide member 20. Next, when the operator places the drug 5 on the placement plate 11 visible in the space created in FIG. 11(a) and releases his / her hand from the opening 21, the slide member 20 is pulled by the spring 15 toward the reference surface 12a. Naturally, the slide member 20 comes into contact with the drug 5 placed on the mounting plate 11 and stops with the drug 5 sandwiched between it and the side wall 12, so that the measurement surface 20a, which is the tip of the slide member 20, and the reference surface 12a face each other with a distance L1 between them when the drug 5 is placed.

[0040] As already described, a protrusion 23 that fits into the slide volume 18a is formed on the back surface of the slide member 20, and the slide volume 18a moves only along the ±A direction along which the variable resistor 18 extends. Therefore, the slide member 20 is guided by the variable resistor 18 so that it moves only in the A direction, and when the distance between the reference surface 12a and the measurement surface 20a coincides with the dimension L1, this dimension L1 can be measured from the resistance value of the variable resistor 18. In this way, the variable resistor 18 functions as a guide that defines the moving direction of the slide member 20 in the sliding direction, and also functions as a detection means that detects how far the slide member 20 has moved from the distance between the reference surface 12a and the measurement surface 20a.

[0041] Now, although it is said that the dimensions of the drug 5 are measured, the shapes of the drug 5 vary, and it is also possible that different people will assume different positions when expressing the "width" or "diameter" of the drug 5.

[0042] For example, in the case of a drug having an elliptical cylindrical shape as shown in Figures 12(a) to (c), which of the three dimensions L1, L2, and L3 is considered to be the "diameter" may differ depending on the operator. Also, it may be expressed as "length," "width," or "thickness," or it may be expressed as "length," "width," or "depth." Furthermore, if these recognitions differ, there is a concern that, for example, when recording this dimensional information in the drug master 502, the width of the drug referred to by the regulating mechanism 70 of the drug feeder 240 and the height of the drug referred to by the sorting unit 60 may be confused.

[0043] Therefore, in order to minimize such mix-ups, the drug dimension measuring device 100 of the present invention has a measurement position selection button 31 on side 13, which is the side that the operator can easily operate with his thumb, and also has display LEDs 41, 42, and 43, which are three light-emitting elements that each emit light corresponding to the number of times the measurement position selection button 31 is pressed. In Figure 12 etc., when the measurement position selection button 31 is pressed once, the display LED 41 lights up, when the measurement position selection button 31 is pressed twice, the display LED 42 lights up, and when the measurement position selection button 31 is pressed three times, the display LED 43 lights up. However, it is sufficient if the configuration allows the position at which measurement is being performed to be indicated by the number of times the button is pressed via the display LEDs 41, 42, 43. In addition, the shapes of the display LEDs 41, 42, 43 are modeled after the shapes of a typical oval tablet or a bale-shaped drug, so that it is easy to understand at a glance which position on the drug 5 should be measured in response to the respective number of times the measurement position selection button 31 is pressed. Specifically, as shown in Figures 13(a), (b), and (c), the display LEDs 41, 42, and 43 are formed so that the measurement positions of the dimensions L1, L2, and L3 respectively coincide with the way in which the drug 5 is placed on the mounting plate 11 when measuring such measurement positions. Here, for example, the direction shown in Figure 13(a) corresponding to display LED 41 is defined as the "diameter" dimension of drug 5, the direction shown in Figure 13(b) corresponding to display LED 42 is defined as the "width" dimension of drug 5, and the direction shown in Figure 13(c) corresponding to display LED 43 is defined as the "depth" dimension of drug 5. In addition, the names of the dimensions may be written on each of the measurement position selection buttons 31 arranged on the side of the drug dimension measurement device 100 or on each of the display LEDs 41, 42, 43 so as to correspond to the "length", "width", "thickness", etc. In this embodiment, "Diameter", "Width", and "Depth" are displayed.

[0044] The operator presses the measurement position selection button 31, references the correspondingly lit display LED 41, places the medicines 5 on the placement plate 11 in the same arrangement, and performs the measurement as shown in FIG. 12(c). When the operator presses the send button 34 in the state shown in Figure 12(c), the control unit 16 calculates the distance L between the reference surface 12a and the measurement surface 20a from the resistance value of the variable resistor 18 at that time, and transmits this distance L to the drug packaging machine 200 as the dimension L1 when the measurement position selection button 31 is selected.

[0045] Similarly, when the operator presses the measurement position selection button 31 again, the display LED 41 turns off and the display LED 42 turns on, and the operator positions the drug 5 according to the shape seen by the display LED 42 as shown in Figure 12 (d). When the operator presses the send button 34 in the state shown in Figure 12(d), the distance L between the reference surface 12a and the measurement surface 20a changes to L2 due to the force of the slide member 20 by the spring 15, and the control unit 16 transmits this dimension L2 to the drug packaging machine 200 as the dimension when the measurement position selection button 31 is pressed twice, i.e., dimension L2. The same is true for FIG. 12(e), where a measurement corresponding to the dimension L3 corresponding to the dimension when the measurement position selection button 31 is pressed three times is performed and transmitted when the send button 34 is pressed. Here, the display LED 41 lights up at the start, so that once, twice, and three times correspond to the dimensions L1, L2, and L3, respectively, but it is sufficient if it switches according to the number of times it is pressed. For example, if the display LED 42 lights up when pressed once, it can be changed to the display LED 43 when pressed twice, and the display LED 41, etc. In this way, the measurement position selection button 31 functions as a measurement position information switching means for switching the measurement position information transmitted when the send button 34 is pressed, and it is preferable to provide a display LED to make it easier to visually confirm such measurement position information.

[0046] In this way, in the present invention, the operator can perform measurement without being confused about the positioning of the drug 5 on the mounting plate 11, and without the positioning changing depending on the operator, by lighting up the corresponding display LEDs 41, 42, 43 based on the selection made by pressing the measurement position selection button 31, so that each dimension of the drug 5 can be measured easily and quickly. In this embodiment, the display LEDs 41, 42, 43 are lit up when the measurement position selection button 31 is pressed, but the present invention is not limited to this configuration. For example, the drug dimension measurement device 100 may be provided with a display unit such as a display, and the position where the drug 5 should be measured, i.e., the measurement position, may be displayed on the display. Also, the display LEDs 41, 42, 43 are LEDs shaped to imitate the length, width, and thickness of an oval tablet, but may be displays imitating any tablet shape whose dimensions vary depending on the measurement position of the length, width, and thickness. Thus, by having a measurement position selection button 31 and a display means for visually indicating which measurement position the operator has selected, the present invention makes it possible to easily and quickly measure each dimension of the drug 5.

[0047] In addition, when the transmission button 34, which is a transmission means, is pressed, the control unit 16 transmits the measurement position corresponding to the pressed measurement position selection button (e.g., measurement position selection button 31) and the dimension L1 corresponding to the measurement position as dimensional information to the drug packaging machine 200. As already mentioned, the drug packaging machine 200 has access to data on the drug master 502 in which at least the type of drug 5 is recorded, as shown in FIG. 11. Therefore, when the drug dimension measuring device 100 transmits dimensional information linking the measurement position with the dimensions that are the measurement results at that measurement position, the drug packaging machine 200 can add the dimensional information of the drug 5 to the identification information such as the type and shape of the drug 5 for any drug 5. With this configuration, the drug packaging machine 200 can record the "length," "width," and "thickness" of the drug 5 to be registered as dimensions L1, L2, and L3 corresponding to the drug size, based on uniform standards regardless of the type or shape of the drug 5. Therefore, even when the drug packaging machine 200 is shared among multiple operators, differences in work performed by each operator are reduced, and the drug 5 dimension registration work can be performed efficiently.

[0048] In this embodiment, the dimensional information including at least one of "length", "width", and "thickness" obtained by each operation is linked to the measurement position information determined by the number of times the measurement position selection button 31 is pressed as dimensions L1, L2, and L3, respectively, and transmitted from the drug dimension measurement device 100 to the drug packaging machine 200. Specifically, the dimensional information transmitted by the transmission button 34 when the measurement position selection button 31 is pressed once and the display LED 41 is lit is linked to the drug identification information as the dimension L1 corresponding to the "length" of the drug 5, and is registered in the control device 250 of the drug packaging machine 200 or the drug master 502.

[0049] In this embodiment, the drug 5 has been described as an oval-shaped solid tablet, but the drug 5 is not limited to this configuration, and drug 5 may have various shapes. For example, in the case of a spherical tablet, the only required dimension is the diameter of the tablet, and there is no point in selecting the measurement position selection button 31 for L1, L2, and L3. In such a case, for example, if the drug master 502 contains information on the shape of a spherical tablet, the drug packaging machine 200 referring to the drug master 502 can determine that this is the diameter of the spherical tablet if dimensional information is only recorded in L1, which corresponds to "length" or "diameter." Therefore, the operator first presses the measurement position selection button 31 and measures the dimensions of the drug 5 according to the method of FIG. In addition, as with oval tablets, the drug dimension measuring device 100 transmits the measurement position selection button 31 and the dimension of the drug 5 corresponding to the measurement position selection button 31 as dimensional information to the drug master 502, and the dimensional information is recorded, so no particular problems arise.

[0050] If the shape information of the drug 5 is not recorded, for example, if there is only one piece of dimensional information, it may be presumed to be a spherical tablet, depending on the settings of the drug packaging machine 200. Alternatively, even if the operator measures each of L1, L2, and L3, the same values ​​will all be entered, so when the shape of the tablet is unknown, there is no particular problem even if the operator performs the measurement three times, regardless of the shape, by pressing the measurement position selection button 31 to transmit the measurement result once, then pressing the measurement position selection button 31 again to transmit the second measurement result, and then pressing the measurement position selection button 31 again to transmit the third measurement result, and so on.

[0051] Furthermore, even if the drug 5 has two characteristic dimensions, such as a circular flat tablet or a so-called lenticular tablet, the result will simply be that the "length" and "width" match, so there is no problem with pressing the measurement position selection buttons 31 in turn according to the indications of the display LEDs 41, 42, and 43 and transmitting all of the measurement results. Furthermore, in medicine packaging machine 200, for example, a tablet where dimension L1 = dimension L2 may be determined to have a lenticular or circular shape.

[0052] In this way, the drug dimension measuring device 100 of the present invention can transmit the shape and dimension information of the required drug 5 simply by transmitting the measurement position selected by the measurement position selection button 31 that is pressed when the send button 34 is pressed, and the distance L between the reference surface 12a and the measurement surface 20a when the button is pressed as dimensions L1, L2, and L3, respectively. In this way, the drug dimension measuring device 100 can record the required dimensions and the positions at which those dimensions were measured, regardless of the shape of the solid tablet, and can measure the dimensions of the drug easily and quickly.

[0053] Next, as a second embodiment of the present invention, as shown in FIG. 14, an embodiment will be described which uses a dispensing server 500, a drug packaging machine 200, and a drug dimension measuring device 100 placed in a remote location and connected via a network 505.

[0054] In this embodiment, the configuration of the drug dimension measuring device 100 is substantially the same as that shown in FIG. 6, so the explanation will be omitted as appropriate, but in this embodiment, the drug dimension measuring device 100 is connected via a mobile terminal 300 connected to a network 505. In this configuration, a case where dimensional information of the drug 5 is input using the drug dimension measuring device 100 will be described. In the medicine master 502 in this embodiment, similarly to the case shown in FIG. 11, the identification information of the medicine and the size information can be recorded in association with each other.

[0055] When the operator opens the medicine master 502 via the network 505 using the mobile terminal 300, the operator accesses the data describing the identification information of the medicine 5 and opens a screen similar to that shown in FIG. The operator can use the drug dimension measuring device 100 to measure the dimensions L1, L2, and L3 of the drug 5 in a manner similar to that shown in Figures 12(a) to 12(e), and rewrite the drug master 502 via the network 505 by pressing the send button 34.

[0056] With this configuration, even in a location remote from where the medicine packaging machine 200 is installed, the dimensions of the medicine 5 can be appropriately registered by updating the medicine master 502.

[0057] Alternatively, as a third embodiment, the drug size measuring device 100 may be used alone. At this time, for example, the operator connects the tablet size measuring device 100 to a personal computer 301, which is an arbitrary terminal, and accesses the data in which the identification information of the drug 5 is described. Such data may be, for example, the drug master 502 of the dispensing server 500, or in the case where a stand-alone personal computer 301 is used, it may be obtained by rewriting the identification information of the drug 5 stored in each computer, or it may be obtained by recording the identification information and dimensional information of the drug 5 on some kind of portable recording medium. With this configuration, the operator can pre-record the dimensional information of the drug 5 by adding it to the identification information regardless of the work location. Therefore, even if there are many people around the drug packaging machine 200 and it is not suitable for working, the operator can work in an appropriate location and add the dimensional information of the drug 5, which contributes to work efficiency.

With this configuration, the dimensions of the tablet can be measured easily and quickly.

[0059] <2> In addition, in the drug size measuring device 100 of the present invention, <1> In addition to the configuration described above, the present invention has a display means for visually displaying the measurement position information selected by the measurement position information selection means 31 to the operator.

[0060] <3> In addition, in the drug size measuring device 100 of the present invention, <1> or <2> In addition to the configuration described above, the display means has at least three light-emitting elements, namely, display LEDs 41, 42, 43, and the shapes of the three light-emitting elements, namely, the display LEDs 41, 42, 43, correspond to the measurement positions of the length, width, and thickness of the tablet, respectively. With this configuration, the direction in which the drug 5 is placed when the operator presses and selects the measurement position information selection button is visually clearly displayed, making it less likely for the operator to make an erroneous operation and eliminating the need to be confused about the direction in which the drug 5 is placed, allowing for efficient work.

According to this configuration, when measuring the drug 5, the distance between the reference surface 12a and the measurement surface 20a coincides with the dimension of the drug 5, so that the dimension of the drug 5 can be easily measured. <5> In addition, in the drug size measuring device 100 of the present invention, <1> ~ <4> In addition to the configuration described above, a magnet is attached to the surface that will become the bottom surface when the drug 5 is placed on it. According to this configuration, the drug dimension measuring device 100 can be attached to any position on the housing 201 of the drug packaging machine 200, so that a drug dimension measuring device 100 that is simple and easy to carry can be provided without having to provide a storage or installation space for the drug packaging machine 200 in advance.
