Description

Mixing injection device This invention relates to a mixing injection device. Patent Document 1 discloses an example of a mixing injection device. The mixing injection device of Patent Document 1 includes a drug filling section and a mixing injection processing section. After placing the drug container, the components that can form a syringe, and the delivery fluid container in predetermined positions on a tray placed on the worktable of the drug filling section, the user fills the tray into the mixing injection processing section. In this way, the mixing injection device of Patent Document 1 can begin the mixing injection process. [Prior Art Documents] [Patent Documents] Patent Document 1: Japanese Patent Application Publication No. 2019-063313 (The problem the invention aims to solve) However, in the mixing injection device of Patent Document 1, the operation of filling the mixing injection device with medicine containers, etc., will create a corresponding workload for the user by placing the medicine containers, etc., in a predetermined position on the tray. The purpose of this invention is to reduce the workload of users in the filling operation of mixing injection equipment. (Technical means to solve the problem) To address the aforementioned issues, the present invention provides a mixing injection device comprising: a plurality of device holding sections for holding mixing injection equipment used in mixing injection; and a device conveying section for conveying at least one of the plurality of device holding sections to a working area, wherein the working area is for a user to hold the mixing injection equipment in at least one of the plurality of device holding sections, or for a user to remove the mixing injection equipment held by the device holding section; the device conveying section, based on user motion detection or user conveying instructions, conveys other device holding sections to replace the device holding sections located in the working area. (Effects compared to prior art) According to the present invention, a mixing injection device can reduce the workload of users in the filling operation of mixing injection equipment. The following is a detailed description of one embodiment of the present invention. In the figures, the X-axis and Y-axis are two axes perpendicular to each other in the horizontal plane (the ground plane of the mixing injection device 1). Sometimes the positive direction of the X-axis is referred to as the right direction, and the negative direction as the left direction. Furthermore, sometimes the positive direction of the Y-axis is referred to as the penetration direction, and the negative direction as the forward direction. The Z-axis is an axis extending vertically relative to the XY plane; sometimes the positive direction of the Z-axis is referred to as the upward direction, and the negative direction as the downward direction. [Overall Structure of the Mixing Injection Device] Figure 1 is a perspective view showing an example of the overall structure of the mixing injection device 1. As shown in Figure 1, the mixing injection device 1 of this embodiment includes a syringe holder 10, a vial holder 20, a delivery liquid holder 30, a printing / review unit 50, a delivery liquid receiving unit 60, a waste bin 70, a touch panel 80, and buttons 90. The mixing injection device 1 is an apparatus that performs a mixing injection process (mixing injection action) by mixing a drug and a delivery fluid. For example, the mixing injection device 1 uses a syringe to draw the drug, as indicated in the preparation data, from a vial containing the drug, and injects the drug from the syringe into a delivery fluid container (delivery fluid bag), thereby performing the mixing injection process. The syringe and vial are examples of mixing injection equipment used for mixing injection, and are examples of injection devices used to inject drugs into a delivery fluid container. Other examples of mixed injection treatment include processes where medication is drawn from a vial using a syringe and then injected into another vial, or where delivery fluid is drawn from a delivery container using a syringe and then injected into a vial. When a vial contains a solid medication, the mixed injection device 1 uses a syringe to draw delivery fluid from the delivery container and injects the delivery fluid into the vial. This allows the solid medication in the vial to be liquefied. Then, the mixed injection device 1 uses a syringe to inject the liquid medication into the delivery container. Alternatively, the user can directly perform the mixed injection treatment using the syringe, vial, and delivery container already filled into the mixed injection device 1. The medication used in the mixed injection process can be, for example, a nutrient solution. The delivery fluid used in the mixed injection process can be, for example, a liquid containing saline (physiological saline) or glucose. The delivery fluid after the medication is injected can be, for example, a high-calorie delivery fluid. That is, the mixed injection device 1 of this embodiment mainly uses medications with a low risk of explosion to perform the mixed injection process. Therefore, as will be explained below, the mixed injection device 1 has a simpler structure. That is, in the mixed injection device 1, for example, a user can fill the interior of the mixed injection device 1 with a syringe, vial, and delivery fluid container by opening and closing the door. With this configuration, the mixed injection device 1 can perform the mixed injection process more efficiently than mixed injection devices that use medications with a high risk of explosion. Using the air cleaning unit described later, the interior of the mixed injection device 1 is kept clean, reducing the possibility of contamination of the medication and delivery fluid during the mixed injection process. In addition, in order to keep the interior of the mixed injection device 1 clean, the interior of the mixed injection device 1 is maintained at positive pressure. Furthermore, the aforementioned preparation data is preparation data generated based on prescription data or the prescription data itself. Prescription data includes the date of prescription delivery, patient ID, patient name, patient's date of birth, medication information (drug code, drug name, and dosage, etc.), dosage form information (oral or topical, etc.), usage information (three times daily after meals, etc.), treatment category (visitor or inpatient, etc.), department, ward building, and patient room. In addition, preparation data includes patient information, physician information, medication information, prescription quantity, type of medication container, preparation content information, preparation sequence information, preparation date, prescription classification, administration date, department, ward building, and preparation time, etc. Examples of medication containers for containing the aforementioned medications include ampoules containing liquid medication, vials containing liquid medication, and vials containing powdered medication. In this embodiment, a vial is used as an example for explanation. The information regarding the preparation process can include the types and number of pharmaceutical containers, syringes, and injection needles used in the mixing and injection treatment. The information regarding the preparation procedure can include the work steps, the amount of pharmaceutical solution, the solvent, the amount of pharmaceutical solution, the amount of solvent, and the extraction volume. The syringe rack 10 is an equipment storage rack capable of storing syringes filled into the mixing injection device 1. As an example, the syringe rack 10 is provided with a syringe side door 16. The user can keep the syringe in the syringe rack 10 by opening and closing the syringe side door 16. The vial rack 20 is an equipment storage rack capable of storing vials filled into the mixing and injection device 1. As an example, the vial rack 20 is provided with a vial side door 27. The user can keep the vial 502 in the vial rack 20 by opening and closing the vial side door 27. The delivery rack 30 is a delivery liquid storage rack capable of storing the delivery liquid container filled into the mixing injection device 1. In this embodiment, the delivery rack 30 includes a delivery rack 30S and a delivery rack 30L. The height of the delivery rack 30L is greater than that of the delivery rack 30S. Therefore, the user can store the delivery liquid container in the delivery rack 30S or 30L according to its size. Furthermore, delivery liquid side doors 34S and 34L are provided on the delivery racks 30S and 30L, respectively. The user can keep the delivery liquid container in the delivery liquid side door 34S or 34L by opening and closing the delivery liquid side door 34S or 34L. Alternatively, the delivery liquid side doors 34S and 34L can be collectively referred to as delivery liquid side door 34. In this embodiment, a plurality of syringe holders 10, vial holders 20, and delivery tube holders 30 are provided in the mixing and injection device 1. Each syringe holder 10 is arranged in two layers in a vertical direction. Each vial holder 20 is arranged in three layers in a vertical direction. The syringe holder 10 is located on a higher layer than the vial holder 20. When viewed from the front surface of the mixing and injection device 1, the delivery tube holder 30 is located on the opposite side of the syringe holder 10, separated by a touch panel 80 located near the center of the front surface. The delivery tube holder 30 is arranged in three layers in a vertical direction. The delivery tube holder 30L is located below the two delivery tube holders 30S. Syringe side door 16, vial side door 27, and delivery fluid side doors 34S and 34L are designed to prevent the user from entering or exiting the syringe rack 10, vial rack 20, and delivery fluid rack 30S and 30L, respectively. In the mixing injection device 1, control is performed by the control unit 140 (see Figure 5) to ensure that only one of the following doors is open: syringe side door 16, vial side door 27, and delivery fluid side doors 34S and 34L. As described above, the interior of the mixing injection device 1 is adjusted to positive pressure. By keeping only one door open, the possibility of contamination of the interior of the mixing injection device 1 by external gases is reduced. Button 90 is a mechanical button that allows user operation to open the syringe side door 16, the medicine bottle side door 27, and the delivery fluid side door 34. One button is provided for each of the three side doors, corresponding to the syringe side door 16, the medicine bottle side door 27, and the delivery fluid side door 34. When closed, the syringe side door 16, the medicine bottle side door 27, and the delivery fluid side door 34 are locked by a locking mechanism (not shown). The syringe side door 16, the medicine bottle side door 27, and the delivery fluid side door 34 are only opened when the user presses button 90. However, even when the button 90 is pressed, the closed door remains closed while any of the three doors is open. That is, when any door is opened (when the lock is released), the control unit 140 (described later) disables the user's operation of button 90 corresponding to the closed door. Alternatively, the control unit 140 can lock only the doors of the syringe rack 10, vial rack 20, or delivery fluid rack 30 accessed by the first transfer unit 110 or the second transfer unit 120 (described later). Even with this configuration, the possibility of a user touching the operating first transfer unit 110 or second transfer unit 120 can be reduced. Furthermore, syringes, vials, or delivery fluid containers can be filled into unlocked racks. Therefore, filling efficiency can be improved. In addition, light-emitting members (not shown) can be provided corresponding to the syringe rack 10, vial rack 20, and delivery fluid rack 30, respectively. Even by illuminating the light-emitting members corresponding to the racks accessed by the first transfer unit 110 or the second transfer unit 120, the control unit 140 can still reduce the possibility of a user touching the operating first transfer unit 110 or second transfer unit 120. In this case, it is not necessary to provide locking mechanisms for each door. The printing / review unit 50 is a unit that prints type information labels (described later) and unsuitable information labels (described later) and affixes them to the delivery fluid container after drug injection. Furthermore, the printing / review unit 50 is a unit for measuring the delivery fluid container after drug injection. In this embodiment, the printing / review unit 50 is located on the lower side of the delivery fluid rack 30L. Additionally, the delivery fluid container after drug injection (after mixing and injection treatment) refers to the delivery fluid container after the drug and delivery fluid are mixed. On the other hand, the delivery fluid container before drug injection (before mixing and injection treatment) refers to the delivery fluid container before the drug and delivery fluid are mixed. The delivery fluid receiving unit 60 is a container for receiving delivery fluid containers after injection, which have been affixed with type information labels and / or inappropriate information labels. In this embodiment, the delivery fluid receiving unit 60 is located on the lower side of the printing / review unit 50. The waste bin 70 is a container for receiving used syringes. The touch panel 80 has the functions of an operation unit that accepts various user operations and a display unit that displays various information. The operation unit and the display unit may also be separate components. In addition, a prompting unit (e.g., a speaker) that provides various information may be provided instead of a display unit. In this embodiment, a syringe side door 16, a medicine bottle side door 27, a delivery fluid side door 34, a touch panel 80, and a button 90 are provided on the front surface of the mixing injection device 1. This allows the user to access the syringe holder 10, medicine bottle holder 20, delivery fluid holder 30, and button 90 from the side operating the touch panel 80. Furthermore, in this embodiment, handles are also provided on the front surface of the mixing injection device 1 for the printing / review unit 50, the delivery fluid receiving unit 60, and the waste bin 70, allowing the user to access them from the front surface of the mixing injection device 1. [Summary of the Internal Structure and Operation of the Mixing Injection Apparatus] Figure 2 is a cross-sectional view along line I-I in Figure 1. Figure 3 is a cross-sectional view along line II-II in Figure 1. As shown in Figures 2 and 3, the mixing injection apparatus 1 includes a mixing injection unit 40, a first conveying section 110, a second conveying section 120 (liquid container conveying section), an air cleaning section 130, and a pair of inclined sections 160. The air cleaning section 130 is omitted from the illustration in Figure 2. The mixing injection unit 40 functions as a mixing section for mixing the medication with the delivery fluid in the delivery fluid container. In this embodiment, the mixing injection unit 40 is located opposite the syringe holder 10 and the vial holder 20, and is situated at the central depth of the mixing injection apparatus 1. The first transport unit 110 is configured to transport the syringe from the syringe holder 10 to the mixing injection unit 40, or the vial from the vial holder 20 to the mixing injection unit 40, when modulation data (prescription data) is input. Furthermore, the second transport unit 120 is configured to transport the delivery fluid container from the delivery fluid holder 30 to the mixing injection unit 40. Through these transports, the mixing injection process can be performed in the mixing injection unit 40. The first transport unit 110 grasps the upper part of the main stem of the syringe stored in the syringe rack 10, moves it to the left and rotates it 90 degrees in the XY plane to transport it to the mixing injection unit 40. Similarly, the first transport unit 110 grasps the main stem of the vial stored in the vial rack 20, moves it to the left and rotates it 90 degrees in the XY plane to transport it to the mixing injection unit 40. Furthermore, before transporting the syringes stored in the syringe holder 10 to the mixing injection unit 40, the first transport unit 110 transports them to the cap removal unit 250 (see Figure 11). This allows the first transport unit 110 to remove the needle cap from the syringe needle and install the syringe with the needle cap removed into the mixing injection unit 40. Additionally, the first transport unit 110 transports the syringes and vials (discarded syringes and vials) after the mixing injection process to the waste bin unit 70. The second conveying unit 120 picks up the main stem of the delivery liquid container stored in the delivery liquid rack 30, rotates it 90 degrees in the XY plane, and conveys it to the mixing and injection unit 40. Furthermore, the second conveying unit 120 picks up the main stem of the delivery liquid container after drug injection, conveys it to the printing / review unit 50, and conveys the delivery liquid container after drug injection, which has been affixed with type information labels (and inappropriate information labels), to the delivery liquid receiving unit 60. The air purification unit 130 purifies the air inside the mixing and injection device 1 and then exhausts it. In this embodiment, it is located at the top of the mixing and injection device 1. The purified air from the air purification unit 130 flows from the top to the bottom of the mixing and injection device 1. The air purification unit 130 may include, for example, a HEPA (High Efficiency Particulate Air) filter. A pair of inclined sections 160 allow the delivery liquid container after drug injection to be transported from the second conveying section 120 to the delivery liquid receiving section 60 by the weight of the delivery liquid container itself. Figure 4 shows an example of a pair of inclined sections 160. The pair of inclined sections 160 are guide members that guide the delivery liquid container 503, after being injected with the drug and adsorbed by the second conveying section 120, to the delivery liquid receiving section 60. As shown in Figure 4, in the pair of inclined sections 160, there is a rod-shaped member inclined at an angle where the end on the side of the second conveying section 120 is higher than the end on the end of the delivery liquid receiving section 60. After the second conveying section 120 operates in such a way that the head of the delivery liquid container 503 after being injected with the drug is engaged between the pair of inclined sections 160, it releases the adsorption state on the main body of the delivery liquid container 503 after being injected with the drug. Thereby, the delivery liquid container 503 after being injected with the drug slides along the pair of inclined sections 160 due to its own weight and is discharged to the delivery liquid receiving section 60. That is, with such a simple configuration of a pair of inclined sections 160, the delivery liquid container 503 after being injected with the drug can be discharged to the delivery liquid receiving section 60 by its own weight. Furthermore, the configuration of the components in the mixing injection device 1 is not limited to the configurations described above. For example, the vial rack 20 may be located on the upper layer of the syringe rack 10. Additionally, the positions of the syringe rack 10 and vial rack 20 may be reversed from those of the delivery fluid rack 30. Furthermore, the syringe rack 10, vial rack 20, and delivery fluid rack 30 may be arranged together on either side of the mixing injection device 1, with the mixing injection unit 40 located at a different position from the syringe rack 10, vial rack 20, and delivery fluid rack 30. Alternatively, the syringe rack 10, vial rack 20, and delivery fluid rack 30 may each be arranged in a single layer instead of multiple layers. Furthermore, the positions of the printing / review unit 50 and the delivery fluid receiving unit 60 may be reversed. The configuration of the components in the mixing injection device 1 can be determined by considering user convenience and ease of manufacture. Furthermore, a syringe side door 16 and / or a vial side door 27 can be provided on the side of the mixing injection device 1. As described later, one syringe and one vial are filled from the front surface of the mixing injection device 1. On the other hand, multiple syringes or multiple vials can be filled from the side of the mixing injection device 1. Therefore, by providing a syringe side door 16 and / or a vial side door 27 on the side of the mixing injection device 1, the user can fill the syringe and vial more efficiently. In addition, if the delivery container 30 adopts the same configuration as the syringe holder 10 and the vial holder 20, a delivery container side door 34 can also be provided on the side of the mixing injection device 1. In this case, the user can also fill the delivery container more efficiently. [Other Components] Figure 5 is a block diagram showing an example of the overall configuration of the mixing injection device 1. As shown in Figure 5, it includes a control unit 140 and a memory unit 200. In addition, in Figure 5, only the main hardware components that the control unit 140 can control are shown in the hardware configuration of the mixing injection device 1. The control unit 140 centrally controls the mixing injection device 1. The control unit 140 includes, for example, a syringe transport control unit 141, a vial transport control unit 142, a first transport control unit 143, a mixing injection unit control unit 144, a second transport control unit 145, an injection control unit 147, a printing / review unit control unit 148, a touch panel control unit 149, and a cap loading / unloading control unit 150. The touch panel control unit 149 controls the touch panel 80. Other components of the control unit 140 will be described later along with the descriptions of each component. The memory unit 200 stores various programs and data used by the control unit 140. Hereinafter, the specific configuration of the mixing injection device 1 will be described with reference to FIG5. [Configuration of the Mixing Injection Unit] Figure 6 is a diagram showing an example of the configuration of the mixing injection unit 40. As shown in Figure 6, the mixing injection unit 40 includes a syringe holder 41, a vial holder 42, and a delivery liquid container holder 43. The operation of each component of the mixing injection unit 40 is controlled by the mixing injection unit control unit 144 shown in Figure 5. The syringe holder 41 is a component that holds the syringe 501. The syringe 501 consists of a syringe barrel 5011, a needle 5014, and a plunger 5015. The plunger 5015 is a pushing member that moves in and out relative to the syringe barrel 5011. By moving in and out of the syringe barrel 5011 with the plunger 5015, medications or the like can be drawn into or expelled from the syringe barrel 5011. Furthermore, the syringe barrel 5011 has a needle-side end 5012 on which the needle 5014 is mounted, and a flange 5013 as the end on the plunger 5015's inlet / outlet side. The flange 5013 is the end opposite to the needle-side end 5012. In addition, the vial holder 42 is a component that holds the vial 502. The delivery fluid container holder 43 is a component that holds the delivery fluid container 503. In this embodiment, the syringe holder 41 holds the lower part of the main body (syringe barrel 5011) of the syringe 501. In addition, the syringe holder 41 holds the syringe at the needle-side end 5012 and the flange 5013. The vial holder 42 and the delivery container holder 43 hold the heads of the vial 502 and the delivery container 503, respectively. The syringe holder 41 includes a pair of needle clamping portions 411, a syringe clamping portion 412, a base 415 (see Figure 7), and a pair of first syringe holders 416. The base 415 is a component provided with a pair of second syringe holders 413 and a pair of needle clamping portions 411, which will be described later. Furthermore, the base 415 is configured to be movable in the vertical direction by means of the mixing injection unit control unit 144. A pair of needle clamping portions 411 are components that clamp the needle 5014. The pair of needle clamping portions 411 clamp the needle 5014, positioning the tip of the needle 5014 in a predetermined position. This allows even a bent needle 5014 to pierce the plug located in the delivery fluid container 503 at the desired (correct) position during the mixing injection process. Furthermore, in this embodiment, the pair of needle clamping portions 411 function as electrodes. By functioning the pair of needle clamping portions 411 as electrodes, the mixing injection unit control unit 144 can detect the state of liquid (e.g., medication or delivery fluid) adhering to either needle clamping portion of the pair of needle clamping portions 411. Specifically, when liquid is adhering to either one of the two needle clamping portions constituting the pair of needle clamping portions 411, the pair of needle clamping portions 411 becomes conductive via the liquid when the two needle clamping portions approach each other. The mixing injection unit control unit 144 can detect the state of liquid adhering to a pair of needle clamps 411 by detecting the conduction. Here, when liquid adheres to needle 5014, the liquid will adhere to the pair of needle holders 411. Therefore, in this case, when the pair of needle holders 411 subsequently hold the needle 5014 of another syringe 501, the liquid will adhere to the needle 5014. In other words, contamination will occur in this case. As shown in Figure 5, the mixing injection unit control unit 144 includes a liquid detection unit 1441. The liquid detection unit 1441 detects whether liquid adheres to the pair of needle clamping portions 411. Specifically, when the needle 5014 is positioned between the two needle clamping portions constituting the pair of needle clamping portions 411, the mixing injection unit control unit 144 moves the two needle clamping portions closer together until they are about to clamp the needle 5014 (at a position slightly spaced from the needle 5014). In this state, the liquid detection unit 1441 can detect whether liquid adheres to the pair of needle clamping portions 411 by determining whether conductivity is detected in the pair of needle clamping portions 411. If liquid adheres to the pair of needle clamping portions 411, the pair of needle clamping portions 411 are conductive through the liquid. Therefore, the liquid detection unit 1441 can detect the presence of liquid in the pair of needle clamping portions 411. Then, when liquid is detected adhering to the pair of needle holders 411, the touch panel control unit 149 can display an image on the touch panel 80 indicating that liquid is adhering to the pair of needle holders 411. At this time, the user can be urged to clean the pair of needle holders 411. Therefore, the possibility of the above-mentioned contamination can be reduced. Alternatively, the mixing injection unit control unit 144 can also bring the two needle clamping portions closer together until the needle is about to be clamped, before the first conveying unit 110 holds the syringe 501 in front of the syringe holding portion 41 (i.e., before the needle 5014 is positioned between the two needle clamping portions). Even in this case, when liquid adheres to the pair of needle clamping portions 411, the pair of needle clamping portions 411 are still connected via the liquid. Therefore, the liquid detection unit 1441 can detect when liquid adheres to the pair of needle clamping portions 411. The pair of needle clamping portions 411 is an example of the needle holding portion of the needle holding portion 5014. That is, the syringe holding portion 41 does not necessarily need to have a pair of needle clamping portions 411; any component that holds the needle 5014 is sufficient. In this case, in addition to the pair of needle clamping portions 411, a pair of electrodes that are conductive when liquid adheres to the pair of needle clamping portions 411 may also be provided. Furthermore, when referring to "a pair of components" in this specification, a pair of components does not necessarily have to be "a pair" as long as the function of the component can be performed. The pair of first syringe holders 416 are components that initially hold the syringes 501 transported from the syringe holder 10 by the first conveying unit 110. The pair of first syringe holders 416 clamp the sides of the syringes 5011 (e.g., the lower part of the syringe 5011) inserted into the pair of first syringe holders 416 from the left and right directions. The syringe clamping part 412 is a component that clamps the syringe 501 along the extending direction of the syringe 501 between the needle-side end 5012 and the flange 5013. Specifically, the syringe clamping part 412 includes a pair of second syringe holders 413 and a pair of third syringe holders 414. The pair of second syringe holders 413 is an example of a syringe holder that holds the needle-side end 5012. In this embodiment, when the syringe 501 is held by the syringe clamping part 412, a pair of second syringe holding parts 413 abut against the lower side of the needle-side end 5012, and a pair of third syringe holding parts 414 abut against the upper side of the flange 5013. In this way, the syringe clamping part 412 can clamp the syringe 501 along its extending direction. For example, when the side of the syringe 5011 is held only by a pair of first syringe holders 416, a certain degree of force is required to hold the syringe 5011 in a manner that prevents it from sliding in the extending direction of the syringe 501. Therefore, there is a possibility that the syringe 5011 may deform due to the force applied. By holding it along the extending direction of the syringe 501, the syringe holder 412 can use a smaller force than when holding the side of the syringe 5011 to fix it in a manner that prevents it from sliding in the extending direction of the syringe 501. This reduces the possibility of deformation of the syringe 5011. A pair of second syringe holders 413 have a mortar-shaped form (see Figure 7) capable of fitting the needle-side end 5012. The cross-sectional shape of the needle-side end 5012 has a triangular shape with the needle mounting side as the vertex, or a trapezoidal shape where the side of the needle mounting side is shorter than the side of the main body of the syringe 5011. Therefore, in the cross-sectional shape of the pair of second syringe holders 413, the portion into which the needle-side end 5012 is inserted has a triangular shape with a vertex on the lower side, or a trapezoidal shape where the lower side is shorter than the upper side, thereby enabling the pair of second syringe holders 413 to fit the needle-side end 5012. Thus, when the syringe clamp 412 clamps the syringe 501, the needle 5014 can protrude entirely from the pair of second syringe holders 413. However, the pair of second syringe holders 413 are not limited to the above-described shape as long as they are capable of fitting the needle-side end 5012. (Operation of the syringe holder) Figure 7 illustrates an example of the operation of the syringe 501 held in the syringe holder 41. Symbol 7001 in Figure 7 indicates the state in which a pair of first syringe holders 416 hold the syringe 501. Symbol 7002 in Figure 7 indicates the state in which a pair of second syringe holders 413 hold the needle-side end 5012. Symbol 7003 in Figure 7 indicates the state in which a pair of third syringe holders 414 hold the flange 5013. Symbol 7004 in Figure 7 indicates the state in which a pair of needle clamps 411 clamp the needle 5014. As shown by symbol 7001 in FIG7, the first conveying unit 110 holds the syringe 501 conveyed from the syringe holder 10 in a pair of first syringe holders 416. In this state, the needle-side end 5012 is not engaged in the pair of second syringe holders 413. Next, as shown by symbol 7002 in FIG7, the mixing injection unit control unit 144 moves the base 415 upward. Hereby, the needle-side end 5012 engages in the pair of second syringe holders 413. With the needle-side end 5012 engaged with a pair of second syringe holders 413, the mixing injection unit control unit 144 moves the base 415 further upward. Thus, as shown by reference numeral 7003 in FIG7, a pair of third syringe holders 414 abut against the flange 5013 (the eaves of the syringe 5011). In this state, the syringe clamping part 412 clamps the syringe 501 at the needle-side end 5012 and the flange 5013 along the extending direction of the syringe 501. Furthermore, the mixing injection unit control unit 144 can detect the force applied in the extension direction of the syringe 501. When the force applied in the extension direction of the syringe 501 is above a predetermined value, the mixing injection unit control unit 144 can determine that the pair of third syringe holders 414 abut against the flange 5013 while the needle-side end 5012 is engaged with the pair of second syringe holders 413. The predetermined value can be predetermined through experiments, etc. When the force is determined to be above a predetermined value, the mixing injection unit control unit 144 stops the upward movement of the base 415. Then, as shown by the symbol 7004 in FIG7, the mixing injection unit control unit 144 clamps the needle 5014 by moving the pair of needle clamping parts 411 toward the needle 5014 side. (Detection and Processing of Contamination Status of a Pair of Needle Clamping Parts) Figure 8 is a flowchart illustrating an example of the detection and processing of contamination status of a pair of needle clamping parts 411. As shown in Figure 8, the mixing injection unit control unit 144 determines that the pair of third injection barrel holding parts 414 abut against the flange 5013 while the needle-side end 5012 is engaged with the pair of second injection barrel holding parts 413. At this time, the mixing injection unit control unit 144 moves the two needle clamping parts constituting the pair of needle clamping parts 411 closer together until the position where the needle is about to be clamped is reached (S1). Then, the liquid detection unit 1441 determines whether the pair of needle clamping parts 411 is conductive (S2). When the liquid detection unit 1441 determines that the pair of needle clamping parts 411 is conductive ("YES" in S1), the touch panel control unit 149 displays an image on the touch panel 80 to urge the user to clean the pair of needle clamping parts 411 (S3). This encourages the user to clean the pair of needle clamping parts 411, thereby reducing the possibility of contamination. On the other hand, when the liquid detection unit 1441 determines that the pair of needle clamping parts 411 is not conductive ("NO" in S2), the pair of needle clamping parts 411 clamp the needle (S4). Additionally, as described above, in S1, the mixing injection unit control unit 144 can also bring the two needle clamping parts closer to the position where the needle is about to be clamped before the first conveying unit 110 holds the syringe 501 in the syringe holding part 41. In this case, when S2 is "NO", the needle clamping parts 411 can also clamp the needle after the first conveying unit 110 holds the syringe 501 in the syringe holding part 41. [Configuration of the First and Second Transport Units] (Configuration of the First Transport Unit) Figure 9 shows an example of the configuration of the first transport unit 110. As shown in Figure 9, the first transport unit 110 includes a first claw portion 111, a second claw portion 112, and a rotating shaft portion 113. The operation of each component of the first transport unit 110 is controlled by the first transport control unit 143. Furthermore, the movement of the first transport unit 110 between the syringe holder 10 or the vial holder 20 and the mixing injection unit 40 is also controlled by the first transport control unit 143. The first claw portion 111 and the second claw portion 112 are respectively components that hold the upper part of the syringe barrel 5011 of the syringe 501 or the head of the vial 502. The first claw portion 111 and the second claw portion 112 only need to be configured to hold the syringe 501 and the vial 502. In this embodiment, the mixing injection unit 40 holds the lower part and both ends of the syringe barrel 5011 of the syringe 501 and the main body of the vial 502. Therefore, in this embodiment, the first conveying part 110 is configured to hold the upper part of the syringe barrel 5011 of the syringe 501 or the head of the vial 502. This allows the position where the mixing injection unit 40 holds the syringe 501 or vial 502 from both radial sides to be different from the position where the first conveying part 110 holds the syringe 501 or vial 502 from both radial sides. Therefore, even if the first conveying section 110 is brought close to the first syringe holder 416, the first conveying section 110 and the first syringe holder 416 will not come into contact with each other. Thus, the first conveying section 110 can bring the syringe 501 or vial 502 close to the mixing injection unit 40, or close to the syringe 501 or vial 502 held in the mixing injection unit 40. This allows for efficient transfer of the syringe 501 or vial 502 to the mixing injection unit 40. Furthermore, the rotating shaft 113 is a shaft extending in the vertical direction, allowing the first claw 111 and the second claw 112 to rotate in the XY plane. Because the first conveying unit 110 has a first claw 111 and a second claw 112, it can efficiently perform the mixed injection process. For example, in the mixed injection process, in order to convey the syringe 501 or vial 502 used for the next mixed injection process to the mixed injection unit 40, the first conveying control unit 143 first causes the first claw 111 to clamp the syringe 501 or vial 502. Then, in order to receive the syringe 501 or vial 502 after the mixed injection process is completed from the mixed injection unit 40 and convey it to the waste bin unit 70, the first conveying control unit 143 causes the second claw 112 to clamp the syringe 501 or vial 502. Then, with the syringe 501 or vial 502 held by the first claw 111, the first conveying control unit 143 conveys the first conveying unit 110 to the mixed injection unit 40. Therefore, it is possible to shorten the time that the syringe 501 or vial 502 used in the subsequent mixing injection process is kept in the first conveying section 110 and conveyed to the mixing injection unit 40 after the syringe 501 or vial 502 is moved to the waste bin section 70. In addition, the first conveying unit 110 is a conveying unit shared by the syringe 501 and the medicine bottle 502, but it is not limited to this. It is also possible to provide a dedicated conveying unit for conveying the syringe 501 and a dedicated conveying unit for conveying the medicine bottle 502. (Composition of the Second Conveyor Unit) Figure 10 is a diagram showing an example of the configuration of the second conveyor unit 120. As shown in Figure 10, the second conveyor unit 120 includes an adsorption unit 121 and a third reading unit 122. The movement of each component of the second conveyor unit 120 is controlled by the second conveyor control unit 145. Furthermore, the movement of the second conveyor unit 120 between the mixing injection unit 40 and the printing / reviewing unit 50 is also controlled by the second conveyor control unit 145. The adsorption section 121 is configured to adsorb the main body 5031 of the delivery liquid container 503. The second conveying section 120 is configured to hold the delivery liquid container 503. In this embodiment, the mixing injection unit 40 holds the head of the delivery liquid container 503. Therefore, in this embodiment, the second conveying section 120 is configured to hold the main body 5031 of the delivery liquid container 503. This ensures that the holding position in the delivery liquid container 503 when the mixing injection unit 40 holds the delivery liquid container 503 is different from the holding position when the second conveying section 120 holds the delivery liquid container 503. Therefore, even if the adsorption section 121 (delivery liquid holding mechanism) of the second conveying section 120 is brought close to the delivery liquid container holding section 43 (delivery liquid holding mechanism) of the mixing injection unit 40, the delivery liquid container holding section 43 and the adsorption section 121 will not come into contact with each other. Therefore, the second conveying unit 120 can bring the delivery liquid container 503 close to the mixing injection unit 40, or close to the delivery liquid container 503 held in the mixing injection unit 40. This enables efficient transfer of the delivery liquid container 503 to the mixing injection unit 40. The third reading unit 122 reads the label information contained in the delivery fluid label affixed to the main body 5031 of the delivery fluid container 503. The label information read by the third reading unit 122 may include, for example, information indicating the type of delivery fluid. When the label information is contained in the barcode, the third reading unit 122 can utilize a barcode reader. [Composition of the cap attachment / removal section] Figure 11 is a diagram showing an example of the composition of the cap attachment / removal section 250. The cap attachment / removal section 250 is for attaching and removing the needle cap 5016 of the syringe 501. In the syringe 501 filled in the syringe holder 10, the needle cap 5016 is attached to the needle 5014. As shown in Figure 11, in this embodiment, the cap insertion / removal unit 250 includes a cap insertion part 251, a pair of cap clamping parts 252, and a solenoid 253. The cap insertion part 251 is a member that inserts the needle cap 5016 of the needle 5014 mounted on the syringe 501, and pushes the inserted needle cap 5016 towards the syringe barrel 5011 by a spring (not shown). The pair of cap clamping parts 252 are portions that clamp the needle cap 5016 under the control of the solenoid 253. The solenoid 253 controls the opening and closing of the pair of cap clamping parts 252. A spring (not shown) is provided in the cap insertion part 251, and the solenoid 253 is activated when the spring is shortened to a predetermined length or less. This closes the pair of cap clamping parts 252. Conversely, the solenoid 253 is disconnected by the cap insertion / removal control unit 150, thereby opening the pair of cap clamping parts 252. Figure 12 shows the state when the cap removal section 250 removes the needle cap 5016 from the syringe 501. As shown by symbol 12001 in Figure 12, the first conveying section 110 conveys the syringe 501, which has been removed from the syringe holder 10, to the cap removal section 250. Then, as shown by symbol 12002 in Figure 12, the first conveying section 110 inserts the needle cap 5016 of the syringe 501 into the cap removal section 250 (specifically, the cap insertion section 251), and uses the needle cap 5016 to press down the member that has been subjected to force by the spring against the force of the spring. Next, when the spring reaches a predetermined length or less, the solenoid 253 is connected, and the pair of cap clamping sections 252 are closed. Thus, the cap removal section 250 is in a state of clamping the needle cap 5016. Then, as shown by symbol 12003 in Figure 12, the first conveying section 110 moves away from the cap removal section 250. In this way, the needle cap 5016 is removed from the syringe 501. Therefore, the first conveying unit 110 can convey the syringe 501 with the needle cap 5016 removed to the mixing injection unit 40. Here, when only the needle cap 5016 is held and removed from the needle 5014, there is a risk that the needle 5014 may move together with the needle cap 5016 and be detached from the syringe 5011. As described above, after the needle cap 5016 is pressed into the cap removal part 250, the cap removal part 250 holds the needle cap 5016. By pressing the needle cap 5016 in against the force of the spring, the needle cap 5016 pushes the needle 5014 contained in the needle cap 5016 toward the syringe 5011, and the needle 5014 is more firmly fitted into the syringe 5011 than the needle cap 5016. Therefore, when the needle cap 5016 is removed from the needle 5014, the needle 5014 can be removed without being detached from the syringe 5011. Alternatively, the needle cap 5016 can be pressed into the cap loading / unloading section 250 by moving the first conveying section 110 relative to the cap loading / unloading section 250, but this is not a limitation. For example, the first conveying section 110 may stop when the needle cap 5016 is about to be inserted into the cap loading / unloading section 250 or has already been inserted into the cap loading / unloading section 250, and then the cap loading / unloading section 250 moves toward the first conveying section 110 to press the needle cap 5016 into the cap loading / unloading section 250. Furthermore, the first conveying unit 110 conveys the syringe 501 after the mixed injection treatment to the cap loading / unloading unit 250, inserts the needle 5014 of the syringe 501 into the needle cap 5016 held by the cap loading / unloading unit 250, so that the needle 5014 and the needle cap 5016 are engaged. In this state, the cap loading / unloading control unit 150 disconnects the solenoid 253, thereby opening the pair of cap clamping parts 252. Then, the first conveying unit 110 moves away from the cap loading / unloading unit 250. This allows the needle cap 5016 to be installed on the syringe 501 after the mixed injection treatment. Therefore, the first conveying unit 110 can discard the syringe 501 after the mixed injection treatment with the needle cap 5016 installed into the waste bin 70. [Composition of the Syringe Holder] The detailed composition of the syringe holder 10 will now be described based on Figures 13 to 16. Figure 13 is a perspective view showing an example of the overall composition of the syringe holder 10 and the medicine bottle holder 20. Figure 14 is a perspective view showing an example of the composition of one syringe holder 10 and one medicine bottle holder 20. Figure 15 is a perspective view showing an example of the composition of one syringe holder 10 and one medicine bottle holder 20 when viewed from a different direction than Figure 14. Figure 16 is a diagram showing an example of the composition of one syringe holder 10 and one medicine bottle holder 20 when viewed from the side of the first conveying section 110. As shown in Figures 13-15, the syringe holder 10 includes a plurality of instrument holding sections 11, instrument conveying sections 12, object detection sections 13, syringe detection sections 14, needle detection sections 15, and syringe detection sections 17. The components in the syringe holder 10 related to the conveying of the syringe 501 are controlled by a syringe conveying control section 141. Additionally, an instrument holding section 11 is also installed on the mounting section 1211 of the instrument conveying section 12 shown in Figure 13, but its illustration is omitted. Prior to the mixed injection treatment, the user fills the syringe 501 in the syringe holder 10. The syringe 501 is filled in the syringe holder 10 with the needle cap 5016 attached to the needle 5014. In this embodiment, as shown in Figures 13 and 14, a plurality of holes 172 are formed in the plate-shaped member 171 of each syringe holder 10. This allows, for example, the air purified by the air purification unit 130 (see Figure 3) to flow efficiently from the top to the bottom of the mixing injection device 1. Therefore, the entire space within the mixing injection device 1 can be kept clean. The plurality of device holding parts 11 are components capable of holding syringes 501. In this embodiment, one syringe 501 is held in one device holding part 11, but a plurality of syringes 501 can also be held in one device holding part 11. In this embodiment, as shown in FIG16, the device holding part 11 includes a pair of free rollers 1111 and a pair of device clamping parts 1112. A pair of device clamping parts 1112 clamp the syringe 501. In this embodiment, the pair of device clamping parts 1112 clamp the flange 5013 of the syringe 501. Hereby, the device holding part 11 holds the head of the syringe 501. Furthermore, in this embodiment, the pair of device clamping parts 1112 are provided on the upper part of the syringe holder 10. Hereby, the syringe 501 is held in the device holding part 11 with the needle cap 5016 (needle 5014) located on the lower side. The pair of device clamping parts 1112 are configured such that when the syringe 501 is held in the device holding part 11, the syringe 501 cannot reach a height approximately equal to that of the plate-shaped member 171. In this embodiment, in the mixing injection unit 40, the syringe 501 is arranged with the needle 5014 positioned below. Therefore, a pair of instrument clamping portions 1112 are provided on the upper part of the syringe holder 10. Furthermore, the cap removal portion 250 (see Figure 11) is also arranged at the lower part of the mixing injection device 1 with the cap insertion portion 251 facing upwards, taking this point into consideration. However, for example, in the mixing injection unit 40, when the syringe 501 is arranged with the needle 5014 positioned above, the pair of instrument clamping portions 1112 may also be provided at the lower part of the syringe holder 10. Furthermore, regarding the cap removal portion 250, it may also be arranged at the upper part of the mixing injection device 1 with the cap insertion portion 251 facing downwards. A pair of device clamping portions 1112 are forceped in a direction that brings them closer together, enabling them to clamp the syringe 501. In this embodiment, the pair of device clamping portions 1112 are spaced apart by a gap smaller than the width of the flange 5013 when not clamping the flange 5013. When the flange 5013 is inserted between the pair of device clamping portions 1112, the pair of device clamping portions 1112 move in accordance with the shape of the flange 5013. This allows the pair of device clamping portions 1112 to clamp the syringe 501. A pair of free rollers 1111 are provided below the front end of a pair of instrument clamping parts 1112, each having a rotating shaft extending in the vertical direction and capable of rotating in the XY plane. The pair of free rollers 1111 hold the syringe 5011 near the flange 5013 held by the pair of instrument clamping parts 1112. The equipment conveying unit 12 is a component that conveys at least one of a plurality of equipment holding parts 11 to the work area Ar1. In this embodiment, the equipment conveying unit 12 is a ring-shaped rotating component formed by connecting a plurality of equipment holding parts 11. Therefore, in this embodiment, the equipment conveying unit 12 conveys the equipment holding parts 11 one by one to the work area Ar1. However, the equipment conveying unit 12 may also be a conveying unit that conveys a plurality of equipment holding parts 11 to the work area Ar1 at once. Here, the working area Ar1 is the area where the user holds the syringe 501 in at least one of the plurality of device holding parts 11, and the user removes the syringe 501 held in at least one of the plurality of device holding parts 11. That is, the working area Ar1 functions as a filling location where the syringe 501 can be filled, and as a retrieval location where the syringe 501 can be retrieved. In this embodiment, the working area Ar1 is the area where the user holds the syringe 501 in one device holding part 11, and the user removes the syringe 501 held in one device holding part 11. Furthermore, in this embodiment, the working area Ar1 is located on the syringe side door 16 side shown in FIG1. ​​Thereby, the user can fill the syringe 501 into the device holding part 11 from the syringe side door 16 side, and remove the syringe 501 held in the device holding part 11. In addition, the syringe side door 16 functions as a door that can prevent the user from entering or leaving the working area Ar1. Alternatively, the working area Ar1 can also function solely as the area where the user holds the syringe 501 in at least one of the plurality of device holding parts 11. In this case, the area where the user removes the syringe 501 held in the device holding part 11 can be located at another position outside the working area Ar1. Furthermore, in this embodiment, the device transport unit 12, based on user motion detection, transports other device holding units 11 to replace the device holding unit 11 located in the work area Ar1. For example, the device transport unit 12 changes the device holding unit 11 located in the work area Ar1 by rotating counterclockwise. Through this transport action, other device holding units 11 that do not hold the syringe 501 can be transported to the work area Ar1 to replace the device holding unit 11 that holds the syringe 501 in the work area Ar1. Therefore, the user only needs to hold the syringe 501 in the device holding unit 11 transported to the work area Ar1. This reduces the user's workload caused by the filling operation of the syringe 501. Specifically, the device transport unit 12 transports other device holding units 11 to the work area Ar1 based on the user's action detection indicating that the object detection unit 13 has detected an object (e.g., the user's hand) and no further object is detected. At this time, after the user's hand is inserted into the work area Ar1 and the user holds the syringe 501 in the device holding unit 11, the device transport unit 12 transports other device holding units 11 to the work area Ar1 when the user's hand leaves the work area Ar1. Therefore, the device transport unit 12 can transport other device holding units 11 to the work area Ar1 without the user issuing a transport instruction to the mixing injection device 1. This further reduces the user's workload during syringe 501 filling. Furthermore, the device transport unit 12 does not transport other device holding units 11 to the work area Ar1 until the user's hand leaves the work area Ar1, i.e., while the user's hand is present in the work area Ar1. Therefore, user safety during syringe 501 filling can be ensured. Furthermore, in this embodiment, in addition to detecting the user's actions, the device transport unit 12 also transports other device holding units 11 to the work area Ar1 based on the syringe detection unit 14 detecting that the syringe 501 is held in the device holding unit 11. Therefore, the device transport unit 12 can transport other device holding units 11 to the work area Ar1 after the user holds the syringe 501 in the device holding unit 11 located in the work area Ar1. This reduces the possibility that the device transport unit 12 will transport other device holding units 11 to the work area Ar1 without holding the syringe 501 in the device holding unit 11. The object detection unit 13 is a component that detects objects inserted into the work area Ar1. In this embodiment, the object detection unit 13 detects the user's hand or wrist when the object is inserted into the work area Ar1. The object detection unit 13 uses the side of the syringe holder 10 where the syringe side door 16 shown in FIG. 1 is located (the front side of the mixing injection device 1) as the object detection area. Specifically, the object detection unit 13 is located at a position corresponding to the area between the syringe side door 16 and the device holding part 11 located in the work area Ar1, which constitutes the wall of the syringe holder 10. Furthermore, in this embodiment, in order to improve the detection accuracy of objects entering the work area Ar1, a plurality of object detection units 13 are arranged along the vertical direction of the syringe holder 10. The object detection unit 13 may be, for example, a light sensor consisting of a light-emitting part that emits light and a light-receiving part located opposite the light-emitting part that receives light from the light-emitting part. At this time, when the light-receiving part does not receive light, the object detection unit 13 detects the object. However, the object detection unit 13 can be any type of sensor as long as it can detect objects inserted into the work area Ar1. This also applies to other detection units (sensors). For example, when detecting an object, the object detection unit 13 outputs a detection signal to the control unit 140 during the period when the object is detected. The syringe detection unit 14 is a component that detects the syringe 501 held in the device holding part 11 located in the working area Ar1. In other words, the syringe detection unit 14 functions as a device detection unit for detecting injection equipment held in the device holding part 11 located in the working area Ar1. In this embodiment, when the syringe 501 is held in the device holding part 11, the syringe detection unit 14 detects the syringe barrel 5011. As shown in Figures 13 and 14, the syringe detection unit 14 is provided in a position opposite to the device holding part 11 located in the working area Ar1, which constitutes the wall of the syringe holder 10. The syringe detection unit 14 may, for example, be a light sensor that detects an object by emitting light and receiving light reflected from the object. For example, when detecting the syringe barrel 5011, the syringe detection unit 14 outputs a detection signal to the control unit 140. The needle detection unit 15 detects the needle 5014 of the syringe 501 held in the instrument holding part 11 located in the working area Ar1. In this embodiment, the needle detection unit 15 detects the needle cap 5016 attached to the needle 5014. As shown in Figures 13 and 14, the needle detection unit 15 is provided in a position opposite to the instrument holding part 11 located in the working area Ar1 on the wall constituting the syringe holder 10. In this embodiment, the needle detection unit 15 is arranged in the same row as the syringe detection unit 14 in the vertical direction, but it is not necessary for them to be in the same row. The needle detection unit 15 may be, for example, the same photosensitive sensor as the syringe detection unit 14. Alternatively, the needle detection unit 15 may also function as a syringe detection unit. In this case, the syringe detection unit 14 may not be provided. For example, when the needle cap 5016 is detected, the needle detection unit 15 outputs a detection signal to the control unit 140. Furthermore, in the aforementioned wall portion, the plurality of needle detection units 15 can be arranged in a vertical row with predetermined intervals. In this case, the control unit 140 can estimate the length of the needle 5014 installed in the syringe 501 held in the device holding unit 11 based on whether each of the plurality of needle detection units 15 has detected the needle cap 5016. Therefore, the control unit 140 can determine whether the needle 5014 installed in the syringe 501 held in the device holding unit 11 is suitable. Then, if the control unit 140 determines that the needle 5014 installed in the syringe 501 is unsuitable, the touch panel control unit 149 can also display an image indicating this unsuitability on the touch panel 80. Additionally, information indicating whether each needle detection unit 15 has detected the needle and the length of the needle 5014, as well as information indicating the diameter of the syringe 501 and the length of the needle 5014, can be stored in the memory unit 200. In addition, a plurality of needle detection units for detecting the length of needle 5014 may be provided separately from needle detection unit 15. The syringe detection unit 17 is a component capable of detecting the thickness of the syringe 5011. The syringe detection unit 17 is provided on the wall constituting the syringe holder 10 to detect the position of the syringe 5011 being transported by the instrument transport unit 12. For example, the syringe detection unit 17 may be configured such that the area of ​​the object being detected by the syringe detection unit 17 is inclined relative to the XY plane. The syringe detection unit 17 may be, for example, the same photosensor as the syringe detection unit 14. Alternatively, the syringe detection unit 17 may also function as a syringe detection unit. In this case, the syringe detection unit 14 may not be provided. For example, when detecting a syringe 5011, the syringe detection unit 17 outputs a detection signal to the control unit 140 during the detection period. The memory unit 200 stores information indicating the speed of the instrument transport unit 12 in front of the syringe detection unit 17, and information indicating the thickness of various syringes 5011 that can be used in the mixing injection device 1. After calculating the detection time of the syringe 5011 by the syringe detection unit 17, the control unit 140 calculates the thickness of the syringe 5011 that has passed in front of the syringe detection unit 17 by multiplying that detection time by the speed of the instrument transport unit 12. In this way, the control unit 140 can determine the thickness of the syringe 5011 that has passed in front of the syringe detection unit 17 (i.e., the type of syringe 501). Therefore, the control unit 140 can, for example, determine whether the syringe 501 held in the device holding unit 11 is suitable as a syringe 501 for drawing up the medicine shown in the modulation data (the syringe 501 to be filled into the syringe holder 10). When the control unit 140 determines that the syringe 501 held in the device holding unit 11 is unsuitable as a syringe 501 for drawing up the medicine, the touch panel control unit 149 can display an image indicating the unsuitability on the touch panel 80. In addition, information indicating the type of syringe 501 used to draw up the medicine shown in the modulation data can be stored in the memory unit 200 along with the modulation data. Furthermore, for example, in the memory unit 200, information identifying each device holding unit 11, information indicating the type of syringe 501 held in each device holding unit 11, and information indicating the transport position of each device holding unit 11 can be correspondingly stored. At this time, the first transport control unit 143 can determine the type of syringe 501 that the first transport unit 110 takes out from the device holding unit 11. Therefore, the first transport unit 110 can transport a suitable syringe 501 to the mixing injection unit 40. (Initiation of equipment holding unit transport process) Figure 18 is a flowchart illustrating an example of the process for initiating the transport of the equipment holding unit 11. The symbol 18001 in Figure 18 is a flowchart illustrating an example of the process for initiating the transport of the equipment holding unit 11 by the syringe transport control unit 141. As shown by symbol 18001 in Figure 18, the syringe delivery control unit 141 determines whether the object detection unit 13 has detected the user's hand in the insertion work area Ar1 (S101). When the syringe delivery control unit 141 receives a detection signal from the object detection unit 13, it determines that the user's hand has been detected. When the syringe delivery control unit 141 determines that the user's hand has not been detected (NO in S101), it continues the processing of S101. When the syringe transport control unit 141 determines that a user's hand has been detected (YES in S101), it determines whether the syringe 5011 has been detected by the syringe detection unit 14 (S102). When the syringe transport control unit 141 receives a detection signal from the syringe detection unit 14, it determines that the syringe 5011 has been detected. When the syringe transport control unit 141 determines that the syringe barrel 5011 has been detected (YES in S102), it determines whether the needle 5014 has been detected by the needle detection unit 15 (S103). When the syringe transport control unit 141 receives a detection signal from the needle detection unit 15, it determines that the needle 5014 has been detected. When the syringe transport control unit 141 determines that the needle 5014 has been detected (YES in S103), it determines whether the user's hand cannot be detected in the insertion area Ar1 (S104). For example, if the reception of the detection signal continuously received from the object detection unit 13 is interrupted in S101, the syringe transport control unit 141 determines that the user's hand cannot be detected. When the syringe transport control unit 141 determines that the user's hand cannot be detected (NO in S104), it returns to the processing in S102. When the syringe transport control unit 141 determines that the user's hand cannot be detected (YES in S104), it controls the equipment transport unit 12 to transport other equipment holding units 11 to the work area Ar1 to replace the equipment holding units 11 located in the work area Ar1 (S105). Furthermore, even if the syringe side door 16 is open, but the user's hand is not detected in S104, the syringe transport control unit 141 can transport the device holding unit 11 by controlling the device transport unit 12. The mixing injection device 1 has a detection unit that detects the opening and closing of the syringe side door 16, and the syringe transport control unit 141 can determine whether the syringe side door 16 is open by receiving a detection signal from the detection unit. In addition, when all device holding units 11 hold syringes 501, the syringe transport control unit 141 may not transport the device holding units 11. Furthermore, when the syringe transport control unit 141 determines in S102 that the syringe 5011 has not been detected (NO in S102), it determines whether the undetected state of the syringe 5011 has elapsed for a predetermined time (S107). Specifically, the syringe transport control unit 141 determines whether the state of not receiving a detection signal from the syringe detection unit 14 has elapsed for a predetermined time. The predetermined time can be started, for example, from receiving a detection signal from the object detection unit 13. In addition, the predetermined time can be set to a time that is appropriate for ending this process. When the syringe transport control unit 141 determines that the undetected state of the syringe 5011 has elapsed for a predetermined time (YES in S107), this process ends. On the other hand, when the syringe transport control unit 141 determines that the undetected state of the syringe 5011 has not elapsed for a predetermined time (NO in S107), the process in S102 continues. Furthermore, when the syringe transport control unit 141 determines in S103 that no needle 5014 has been detected (NO in S103), the touch panel control unit 149 displays an image indicating that no needle is detected on the touch panel 80 (S106). This allows the user to identify syringes 501 that are unsuitable for mixed injection processing. Additionally, the processes in S102 and S103 are not necessarily required. (Modification) In this embodiment, as described above, the syringe transport control unit 141 changes the equipment holding unit 11 located in the work area Ar1 to another equipment holding unit 11 based on the user's action detection, indicating that the object detection unit 13 no longer detects the user's hand after detecting it. However, it is not limited to this; for example, the syringe transport control unit 141 can also transport another equipment holding unit 11 to replace the equipment holding unit 11 located in the work area Ar1 based on the user's transport instruction. The syringe transport control unit 141 can, for example, receive the user's transport instruction via a touch panel 80. [Composition of the medicine bottle holder] The detailed composition of the medicine bottle holder 20 will be described below based on Figures 13 to 17. Figure 17 is a diagram for explaining the equipment holding part 21. As shown in Figures 13-15, the medicine bottle rack 20 includes a plurality of equipment holding sections 21, equipment conveying sections 22, object detection sections 23, and medicine bottle detection sections 24. Furthermore, as shown in Figures 16 and 17, it includes a first reading section 25 (reading section) and a roller drive section 26. The components in the medicine bottle rack 20 related to the conveying of medicine bottles 502 are controlled by a medicine bottle conveying control section 142. Additionally, an equipment holding section 21 is also installed on the mounting section 221 of the equipment conveying section 22 shown in Figure 13, but its illustration is omitted. Before the mixed injection process, the user fills the vial holder 20 with vials 502. In addition, similar to the syringe holder 10, a plurality of holes 172 are formed in the plate-shaped member 171 of each vial holder 20. The device holding part 21 is a component capable of holding the medicine bottle 502. In this embodiment, one medicine bottle 502 is held in one device holding part 21, but multiple medicine bottles 502 can also be held in one device holding part 21. In this embodiment, as shown in Figures 16 and 17, the equipment holding part 21 includes a pair of free rollers 211, a pair of equipment clamping parts 212, a drive roller 213, and a first magnet 214. A pair of device clamping parts 212 clamp the medicine bottle 502. In this embodiment, the pair of device clamping parts 212 clamp the head of the medicine bottle 502. Furthermore, in this embodiment, the pair of device clamping parts 212 are provided on the upper part of the medicine bottle holder 20. The pair of device clamping parts 212 are configured such that when the medicine bottle 502 is held in the device holding part 21, the medicine bottle 502 will not touch the plate-shaped member 171 at approximately the same height. A pair of device clamping parts 212 are applied force in a direction that brings them closer together, enabling them to clamp the medicine bottle 502. In this embodiment, the pair of device clamping parts 212 are spaced apart by a gap smaller than the width of the head when not clamping the head of the medicine bottle 502. When the head is inserted between the pair of device clamping parts 212, the pair of device clamping parts 212 move in accordance with the shape of the head. Thus, the pair of device clamping parts 212 are able to clamp the medicine bottle 502. A pair of free rollers 211, each having a rotating shaft extending vertically and rotatable in the XY plane, are provided at the front end of a pair of device clamping portions 212. These free rollers 211, together with a drive roller 213, support the head of the medicine bottle 502 at three points, thereby holding the medicine bottle 502. The drive roller 213 is positioned on one side that pivotally supports the pair of device clamping portions 212, facing the center of the pair of free rollers 211. When the drive roller 213 rotates while holding the medicine bottle 502, the medicine bottle 502 also rotates. Along with this rotation, the pair of free rollers 211 also rotate. By providing a pair of free rollers 211 at the front end of the pair of device clamping portions 212, the possibility of the rotational force of the medicine bottle 502 being reduced due to this front end can be reduced. A first magnet 214 is provided on the upper part of the drive roller 213. The drive roller 213 and the first magnet 214 are connected to a common rotation axis extending in the vertical direction, and can rotate in the XY plane. The first magnet 214 rotates along with the second magnet 261 provided in the roller drive unit 26, thereby causing the drive roller 213 to rotate as well. In this embodiment, the S pole and N pole are arranged alternately on the outer peripheral surfaces of the first magnet 214 and the second magnet 261. The equipment conveying unit 22 is a component that conveys at least one of the plurality of equipment holding parts 21 to the work area Ar2. In this embodiment, the equipment conveying unit 22 is a ring-shaped rotating component formed by connecting the plurality of equipment holding parts 21. Therefore, in this embodiment, the equipment conveying unit 22 conveys the equipment holding parts 21 one by one to the work area Ar2. However, the equipment conveying unit 22 may also be a conveying unit that conveys the plurality of equipment holding parts 21 to the work area Ar2 at once. Furthermore, the work area Ar2, like the work area Ar1, is the area where the user holds the medicine bottle 502 in at least one of the plurality of equipment holding parts 21. In addition, the work area Ar2 is the area where the user removes the medicine bottle 502 held in at least one of the plurality of equipment holding parts 21. In this embodiment, the work area Ar2 is located on the side of the medicine bottle side door 27 shown in FIG. 1. Furthermore, the medicine bottle side door 27 functions as a door that can prevent the user from entering or leaving the work area Ar2. In addition, work area Ar2, like work area Ar1, can also be an area that functions solely as an area for holding medicine bottle 502, or an area that functions solely as an area for removing medicine bottle 502. In this embodiment, the equipment transport unit 22 has the same function as the equipment transport unit 12 shown below. That is, the equipment transport unit 22, based on the detection of the user's action, transports other equipment holding units 21 to replace the equipment holding unit 21 located in the work area Ar2. The equipment transport unit 12, for example, changes the equipment holding unit 21 located in the work area Ar2 by rotating counterclockwise. The equipment transport unit 22, based on the detection of the user's action by the object detection unit 23, transports other equipment holding units 11 to the work area Ar2. Furthermore, in this embodiment, in addition to the detection of the user's action, the equipment transport unit 12 also transports other equipment holding units 11 to the work area Ar2 based on the detection of a medicine bottle 502 held in the equipment holding unit 21 by the medicine bottle detection unit 24. With these configurations, the equipment transport unit 22 can achieve the same effect as the equipment transport unit 12. Furthermore, similar to the syringe transport control unit 141, the vial transport control unit 142 can, for example, be triggered by a user's transport instruction to transport another equipment holding unit 21 to replace the equipment holding unit 21 located in the work area Ar2. The vial transport control unit 142 can, for example, receive the user's transport instruction via a touch panel 80. Additionally, the medicine bottle 502 is provided with a rubber stopper to block the opening and a cap to cover the rubber stopper. A needle from the syringe 501, held by the mixing injection unit 40, is inserted into the rubber stopper. The medicine bottle 502 is filled in the medicine bottle holder 20 with the cap removed. For example, a camera (not shown) can be installed in the medicine bottle holder 20 to photograph the upper part of the medicine bottle 502. In this case, the control unit 140 can determine whether the cap is present or not based on the camera's image. When the medicine bottle 502 has the cap on, the touch panel control unit 149 can display an image on the touch panel 80 urging the user to fill the medicine bottle 502 into the device holding unit 21 with the cap removed. The object detection unit 23 is a component that detects objects inserted into the working area Ar2. In this embodiment, the object detection unit 23 detects the user's hand or wrist when the object is inserted into the working area Ar2. The arrangement of the object detection unit 23 in the medicine bottle holder 20 is the same as that of the object detection unit 13 in the syringe holder 10, and the specific example and function of the object detection unit 23 are also the same as those of the object detection unit 13. The vial detection unit 24 detects the vials 502 held in the equipment holding unit 21 located in the work area Ar2. In other words, the vial detection unit 24 functions as an equipment detection unit for detecting the injection equipment held in the equipment holding unit 21 located in the work area Ar2. The configuration of the vial detection unit 24 in the vial rack 20 is the same as that of the syringe detection unit 14 in the syringe rack 10, and the specific example and function of the vial detection unit 24 are also the same as those of the syringe detection unit 14. The first reading unit 25 is a component that reads type information displayed on the surface of the medicine bottle 502, indicating the type of medicine stored in the medicine bottle 502, during part of the transport path of the medicine transport unit 22 transporting a plurality of medicine holding units 21. Alternatively, a barcode recording type information may be affixed to the medicine bottle 502. In this case, the first reading unit 25 can be a barcode reader. As shown in Figures 16 and 17, the first reading unit 25 is positioned to read the barcode of the vial 502 being transported to a predetermined location. In this embodiment, the predetermined location may be the position where the first conveying unit 110 removes the vial 502. By reading the barcode at the position where the vial 502 is removed, the control unit 140 can identify the type of medicine stored in the vial 502 that is about to be removed. Therefore, the first conveying unit 110 can transport a vial 502 that is suitable for transporting to the mixing injection unit 40. Furthermore, in this embodiment, when viewing the vial rack 20 from the side of the first conveying unit 110, the first reading unit 25 is positioned behind the aforementioned predetermined location. Furthermore, in this embodiment, the first reading unit 25 begins reading the barcode of the medicine bottle 502 when the side door 27 of the medicine bottle is closed. The control unit 140 initiates the reading operation performed by the first reading unit 25 when it detects that the side door 27 of the medicine bottle is closed. According to this configuration, when the user holds the medicine bottle 502 in one of the plurality of device holding units 21, the barcodes (type information) represented by each of the plurality of medicine bottles 502 can be read sequentially when the side door 27 of the medicine bottle is closed. Therefore, barcode reading based on the first reading unit 25 can be performed efficiently. Furthermore, when the equipment transport unit 22 detects that the medicine bottle side door 27 is closed, it can transport the medicine bottle 502 to the position where the first reading unit 25 reads the barcode. Additionally, after the first reading unit 25 completes reading the barcode of the medicine bottle 502, the equipment transport unit 22 can transport the next medicine bottle 502 to the aforementioned position, enabling the first reading unit 25 to perform barcode reading processing for the next medicine bottle 502. As shown in Figure 17, the roller drive unit 26 is a motor that rotates the second magnet 261 mounted on the roller drive unit 26 to rotate the drive roller 213 of the equipment holding unit 21. The rotation axis of the roller drive unit 26 extends in the Y-axis direction, and the second magnet 261 is mounted on this rotation axis. This allows the second magnet 261 to rotate in the XZ plane. For example, the medicine bottle transport control unit 142 can drive the roller drive unit 26 when the medicine bottle 502 is in the barcode reading position of the first reading unit 25. As described above, the first magnet 214 of the equipment holding part 21 is disposed on the upper part of the equipment holding part 21. The arrangement positions of the equipment holding part 21 and the roller drive part 26 are defined such that the first magnet 214 and the second magnet 261 are separated by a distance from each other so that they would be magnetically affected. When the medicine bottle transport control unit 142 drives the roller drive unit 26, the second magnet 261 also rotates. In conjunction with the rotation of the second magnet 261, the first magnet 214 rotates. In conjunction with the rotation of the first magnet 214, the drive roller 213, connected to a rotation axis common to the first magnet 214, rotates, thereby causing the medicine bottle 502, which abuts against the drive roller 213, to rotate. By rotating the medicine bottle 502 in this way, the first reading unit 25 can read the barcode regardless of where it is affixed to the surface of the medicine bottle 502. Alternatively, the first reading unit 25 can also begin reading the barcode on the medicine bottle 502 based on a user's reading instruction. The control unit 140 can, for example, receive the user's reading instruction via a touch panel 80. (Initiation of equipment holding unit transport process) The symbol 18002 in Figure 18 is a flowchart of an example of the process when the medicine bottle transport control unit 142 starts transporting the equipment holding unit 21. As shown by symbol 18002 in Figure 18, similar to S101 in symbol 18001, the medicine bottle transport control unit 142 determines whether a user's hand inserted into the work area Ar2 is detected (S201). When the medicine bottle transport control unit 142 determines that a user's hand has been detected (YES in S201), it determines whether the medicine bottle 502 has been detected by the medicine bottle detection unit 24 (S202). When the medicine bottle transport control unit 142 receives a detection signal from the medicine bottle detection unit 24, it determines that the medicine bottle 502 has been detected. When the vial transport control unit 142 determines that the vial detection unit 24 has detected the syringe 5011 (YES in S202), it determines, in the same way as S104 of symbol 18001, whether the user's hand inserted into the work area Ar2 cannot be detected (S204). When the medicine bottle transport control unit 142 determines that the user's hand can no longer be detected (YES in S204), it controls the equipment transport unit 22 to transport other equipment holding units 21 to the work area Ar2 to replace the equipment holding units 21 located in the work area Ar2 (S205). When the medicine bottle transport control unit 142 determines in S202 that medicine bottle 502 has not been detected (NO in S202), it determines, in the same way as S107 of symbol 18001, whether the undetected state of medicine bottle 502 has passed a predetermined time (S205). (Other Processing) To maintain the filling efficiency of the vial 502 held in the device holding section 21, the following processing may be performed, for example. Figure 19 is a diagram illustrating the efficient filling of the vial 502 held in the device holding section 21. Furthermore, the efficient filling example described below also applies to the efficient filling of the syringe 501 held in the device holding section 11. (Example 1 of efficient filling) The symbol 19001 in Figure 19 is a diagram showing the state in which the two device holding parts 21 that hold the medicine bottle 502 are not in different positions. The symbol 19002 in Figure 19 is a diagram showing the state in which the two device holding parts 21 that hold the medicine bottle 502 are not in adjacent positions. Sometimes, two or more of the plurality of device holding sections 21 may be in a state where they do not hold the vials 502. A device holding section 21 that does not hold the vials 502 may also be referred to as an empty device holding section 21. Furthermore, when two or more empty device holding sections 21 are generated, there is a possibility that at least two of them are in non-adjacent positions. Such a state may occur, for example, when the first conveying unit 110 conveys the vials 502 used in the mixing injection process to the mixing injection unit 40. In the example shown by reference numeral 19001 in FIG19, there are two empty device holding sections 21, and these empty device holding sections 21 are in non-adjacent positions. For example, the memory unit 200 can establish a correspondence between information identifying each device holding section 21, information indicating the type of medicine stored in the medicine bottle 502 held in each device holding section 21, and information indicating the transport position of each device holding section 21, and then store these information. The control unit 140 can, for example, determine that a device holding section 21 is empty if the information indicating the type of medicine does not correspond to the information identifying the device holding section 21. Furthermore, the control unit 140 can use the information identifying the device holding section 21 to determine whether two empty device holding sections 21 are adjacent. When the control unit 140 determines that two empty equipment holding sections 21 are not adjacent, for example, during the standby time of the first conveyor unit 110, it performs the following processing. As shown by reference numeral 19002 in FIG19, the control unit 140 moves the medicine bottle 502 held in the equipment holding section 21 so that the empty equipment holding sections 21 are adjacent. For example, the equipment conveyor unit 22, controlled by the medicine bottle conveying control unit 142, conveys the equipment holding section 21 adjacent to the empty equipment holding section 21 to the position where the first conveyor unit 110 takes out the medicine bottle 502. The first conveyor unit 110, controlled by the first conveying control unit 143, takes out and holds the medicine bottle 502. Herein, the two empty equipment holding sections 21 become adjacent. In this state, the equipment conveyor unit 22 conveys the other empty equipment holding section 21 to the position where the first conveyor unit 110 takes out the medicine bottle 502. The first conveying unit 110 keeps the medicine bottle 502 in the empty equipment holding unit 21. In the case of symbol 19001 in Figure 19, consider the scenario where, after filling an empty equipment holding section 21 with a medicine bottle 502 in work area Ar2, medicine bottles 502 are further filled into other empty equipment holding sections 21. In this case, the equipment transport unit 22 needs to move other empty equipment holding sections 21 located away from the already filled medicine bottle 502 to work area Ar2. In the case of symbol 19002 in Figure 19, two empty equipment holding sections 21 are located in adjacent positions; therefore, compared to the case of symbol 19001 in Figure 19, the moving distance can be shortened. Therefore, the time interval from filling one equipment holding section 21 with a medicine bottle 502 to filling the next equipment holding section 21 can be shortened. (Example 2 for efficient filling) Figure 19, denoted by 19003, illustrates an example of a case where there are multiple adjacent empty equipment holding sections 21. When the medicine bottle side door 27 is open (i.e., when medicine bottles 502 can be filled into the equipment holding section 21), the medicine bottle transport control unit 142 searches for adjacent empty equipment holding sections 21. Starting from the section with the largest number of consecutively adjacent empty equipment holding sections 21, the medicine bottle transport control unit 142 sequentially determines the order in which the empty equipment holding sections 21 are transported to the work area Ar2. In the example of denoted by 19003 in Figure 19, the medicine bottle transport control unit 142 determines the transport order as follows: a portion SP3 of three consecutively adjacent empty equipment holding sections 21, a portion SP2 of two consecutively adjacent empty equipment holding sections 21, and a portion of one empty equipment holding section 21 (denoted by SP1). The equipment transport unit 22 transports portions SP1 to SP3 to the work area Ar2 according to this transport order. At this time, the medicine bottle 502 can be filled sequentially starting from the portion with the largest number of consecutive adjacent empty equipment holding sections 21. Therefore, the aforementioned time interval can also be shortened in this case. [Composition of the Liquid Delivery Rack] Figures 20 and 21 are perspective views showing an example of the composition of the liquid delivery rack 30. Figure 21 is a view with a portion of the wall portion constituting the liquid delivery rack 30 removed. Figure 22 is a perspective view showing an example of the liquid delivery rack 30 viewed from the rear side. As shown in Figures 20 and 21, the liquid delivery rack 30 includes a push-in section 31, a first liquid delivery detection section 32, a push-in conveying section 35, and a pair of track sections 36 (extensions). Furthermore, as shown in Figure 22, it includes a second liquid delivery detection section 33 and a baffle 37. In this embodiment, as described above, liquid delivery racks 30S and 30L are provided as the liquid delivery rack 30, but the liquid delivery racks 30S and 30L differ only in size; their internal mechanisms are identical. Moreover, the components related to the conveying of the liquid delivery container 503 within the liquid delivery rack 30 are controlled by the push-in control section 147. Before the mixed injection treatment, the user fills the delivery fluid container 503 into the delivery fluid rack 30. In addition, similar to the syringe rack 10 and the vial rack 20, a plurality of holes 302 are formed in the plate-shaped member 301 of each delivery fluid rack 30. A pair of track sections 36 are components provided inside the delivery liquid rack 30, extending from the delivery liquid side door 34 (see Figure 1) towards the depth side (i.e., the Y-axis direction) of the mixing injection device 1. Furthermore, as shown in Figure 21, the end of the pair of track sections 36 located on the delivery liquid side door 34 side can be referred to as the door-side end 361, and the end located on the depth side of the mixing injection device 1 can be referred to as the depth-side end 362. At least one delivery liquid container 503 can be suspended from the pair of track sections 36. In this embodiment, the head of the delivery liquid container 503 can be suspended between the pair of track sections 36. That is, the pair of track sections 36 are arranged at a distance sufficient to hold the head of the delivery liquid container 503. By providing a pair of track sections 36, when filling the delivery liquid rack 30 with a plurality of delivery liquid containers 503, the user only needs to suspend the plurality of delivery liquid containers 503 sequentially onto the pair of track sections 36. Therefore, the user can easily fill multiple delivery containers 503 into the delivery rack 30. In this embodiment, each of the liquid delivery racks 30 has three pairs of track sections 36. However, the number of pairs of track sections 36 provided in each liquid delivery rack 30 is not limited to three pairs. Furthermore, a pair of track sections 36 can be filled with a liquid delivery container of the same type (a liquid delivery container containing the same type of liquid and the same size as the liquid delivery container). However, a pair of track sections 36 can also be filled with different types of liquid delivery containers. The push-in part 31 is a component that can move along a pair of track parts 36 to push the delivery liquid container 503, which is suspended on the pair of track parts 36, from the door-side end 361 to the depth-side end 362. In this embodiment, the push-in part 31 is connected to the push-in conveying part 35. The push-in conveying part 35 is provided along the pair of track parts 36. The push-in conveying part 35 is operated under the control of the push-in control part 147, thereby enabling the push-in part 31 to move along the pair of track parts 36. The push-in conveying part 35 can be, for example, a ring-shaped rotating component. The size of the push-in part 31 and the positional relationship between the pair of track parts 36 and the push-in conveying part 35 are defined so that the delivery liquid container 503 suspended on the pair of track parts 36 can be pushed in by the movement of the push-in part 31. When the liquid delivery side door 34 is open, the push-in part 31 is located at position PO0 on the side of the door end 361 and does not obstruct the filling of the liquid delivery container 503 (suspended towards the pair of track parts 36). The push-in control part 147 can, for example, move the push-in part 31 to the above position by controlling the push-in conveying part 35 when the button 90 of the liquid delivery rack 30 (see Figure 1) is pressed (when the liquid delivery side door 34 is open). When the liquid delivery side door 34 is closed, the push-in section 31 pushes the liquid delivery container 503, suspended on a pair of track sections 36, from the door-side end 361 to the depth-side end 362. In this embodiment, when the liquid delivery side door 34 is closed, the push-in control section 147 controls the push-in conveying section 35 to move the push-in section 31 from the aforementioned position PO0 to the depth-side end 362. This allows the user to move the liquid delivery container 503 towards the depth-side end 362 simply by filling the door-side end 361 with the liquid delivery container 503, allowing the second conveying section 120 to remove the liquid delivery container 503. In other words, the second conveying section 120 can efficiently remove the liquid delivery container 503 suspended on the pair of track sections 36. Furthermore, consider the case where a plurality of delivery liquid containers 503 are suspended from a pair of track sections 36, and the second conveying section 120 removes the delivery liquid container 503 located at the depth-side end 362. After the second conveying section 120 removes the delivery liquid container 503, the pushing section 31 pushes the remaining delivery liquid containers 503 suspended from the pair of track sections 36 from the door-side end 361 toward the depth-side end 362. In this embodiment, when the second conveying section 120 removes the delivery liquid container 503 located at the depth-side end 362, the pushing control section 147 controls the pushing conveying section 35 to move the pushing section 31 further toward the depth-side end 362. This allows the remaining delivery liquid containers 503 suspended from the pair of track sections 36 to move toward the depth-side end 362 after the delivery liquid container 503 is removed from the pair of track sections 36. Therefore, the second conveying section 120 can remove the delivery liquid containers 503 more efficiently. The first delivery fluid detection unit 32 detects the delivery fluid container 503 filled into the delivery fluid rack 30. Furthermore, the first delivery fluid detection unit 32 can also detect delivery fluid containers 503 removed from the delivery fluid rack 30. That is, the first delivery fluid detection unit 32 functions as a counting sensor to count the number of delivery fluid containers 503 filled into the delivery fluid rack 30. As shown in Figures 20 and 21, the first delivery fluid detection unit 32 is provided on the door-side end 361 of the wall portion constituting the delivery fluid rack 30. Furthermore, the first delivery fluid detection unit 32 is provided in each pair of track portions 36. The first delivery fluid detection unit 32, for example, like the object detection unit 13 described above, can be a light sensor having an emission portion and a light-receiving portion. In this embodiment, the first delivery fluid detection unit 32 is configured with two sensors adjacent to each other in the Y-axis direction. For example, if the sensor on the delivery fluid side door 34 outputs a detection signal, and then the sensor on the deeper side outputs a detection signal, the control unit 140 can recognize that the delivery fluid container 503 has been filled into the pair of track sections 36. For example, if the sensor on the deeper side (below the sensor on the delivery fluid side door 34) outputs a detection signal, and then the sensor on the delivery fluid side door 34 outputs a detection signal, the control unit 140 can recognize that the delivery fluid container 503 filled into the pair of track sections 36 has been removed. In this way, the control unit 140 can count the number of delivery fluid containers 503 suspended in the pair of track sections 36. Therefore, the control unit 140 can manage the inventory of delivery fluid containers 503 filled in the delivery fluid rack 30. Furthermore, for example, if the inventory falls below a preset baseline inventory quantity, the touch panel control unit 149 can display an image on the touch panel 80 urging the user to fill the delivery fluid container 503. As shown in Figure 22, the second delivery fluid detection unit 33 is provided at the deep end 362 of the wall portion constituting the delivery fluid rack 30, and detects the delivery fluid container 503 present at the deep end 362. Furthermore, like the first delivery fluid detection unit 32, the second delivery fluid detection unit 33 is provided in each pair of track portions 36, and can be a light sensor having an emission portion and a light receiving portion. For example, when the second delivery fluid detection unit 33 detects the delivery fluid container 503 at the deep end 362, it outputs a detection signal. For example, the push-in control unit 147 can determine, after receiving a detection signal from the second delivery fluid detection unit 33 and then no longer receiving the detection signal, that the delivery fluid container 503 located at the deep end 362 has been removed by the second conveying unit 120. Based on this determination, the push-in unit 31 can push the remaining delivery fluid container 503 suspended on a pair of track units 36 from the door end 361 to the deep end 362. The baffle 37 prevents the delivery fluid container 503 located at the deep end 362 from moving in the deep direction (+Y axis direction). The baffle 37 is controlled by the control unit 140 to move in the vertical direction. For example, when the delivery fluid side door 34 is closed, the baffle 37 is controlled by the control unit 140 to be located on the deep side of the delivery fluid rack 30 corresponding to the delivery fluid side door 34. In this way, the possibility of the delivery fluid container 503 located at the deep end 362 falling off the pair of track sections 36 when the push-in part 31 pushes the delivery fluid container 503 suspended on the pair of track sections 36 from the door side end 361 to the deep end 362 can be reduced. In addition, when the second conveying part 120 removes the delivery fluid container 503, the baffle 37 moves to a delivery fluid rack 30 other than the one holding the delivery fluid container 503. (Processing of the push-in control unit) Figure 23 is a flowchart showing an example of the processing of the push-in control unit 147. In Figure 23, the processing of the push-in control unit 147 when the user closes the delivery fluid side door 34 is explained. As shown in Figure 23, the push-in control unit 147 determines whether the liquid delivery side door 34 is in a closed state (S301). If the push-in control unit 147 determines that the liquid delivery side door 34 is not in a closed state (NO in S301), the push-in control unit 147 continues the process of S301. When the push-in control unit 147 determines that the liquid delivery side door 34 is closed (YES in S301), it controls the push-in conveying unit 35 to push the liquid delivery container 503 suspended on a pair of track sections 36 from the door side end 361 to the depth side end 362 (S302). The push-in control unit 147 controls the push-in conveying unit 35 so that the push-in unit 31 pushes the liquid delivery container 503 in until the second liquid delivery detection unit 33 detects the liquid delivery container 503. That is, when the second liquid delivery detection unit 33 detects the liquid delivery container 503, the push-in control unit 147 stops the operation of the push-in conveying unit 35. Through this control, the second conveying unit 120 can remove the liquid delivery container 503 suspended on the pair of track sections 36 from the depth side end 362. The push-in control unit 147 determines whether the second conveying unit 120 has removed the delivery liquid container 503 from the pair of track sections 36 (S303). For example, if the detection signal from the second delivery liquid detection unit 33 is interrupted, the push-in control unit 147 determines that the delivery liquid container 503 has been removed by the second conveying unit 120. If the push-in control unit 147 determines that the second conveying unit 120 has not removed the delivery liquid container 503 (NO in S303), the push-in control unit 147 continues the processing of S303. When the push-in control unit 147 determines that the second conveying unit 120 has removed the delivery liquid container 503 from the pair of track sections 36 (YES in S303), it controls the push-in conveying unit 35 to push the remaining delivery liquid container 503 suspended on the pair of track sections 36 from the door-side end 361 to the depth-side end 362. This enables the second conveying unit 120 to remove the delivery liquid container 503. Additionally, in S302, the push-in control unit 147 can also be triggered by the user's push-in instruction to control the push-in conveying unit 35 by pushing the delivery liquid container 503 suspended on a pair of track sections 36 from the door-side end 361 to the depth-side end 362. The push-in control unit 147 can, for example, receive the user's push-in instruction via a touch panel 80. (Modification) The mechanism for conveying the delivery liquid container 503 in the delivery liquid rack 30 is not limited to the above. For example, the mechanism for conveying the delivery liquid container 503 may be the same as the mechanism for conveying the syringe 501 in the syringe rack 10. That is, a plurality of equipment holding parts and equipment conveying parts can be provided on the delivery rack 30 to replace the push-in part 31, the push-in conveying part 35, and the pair of track parts 36. In this case, the plurality of equipment holding parts are components capable of holding the delivery liquid container 503. The equipment conveying part is a component that transports at least one of the plurality of equipment holding parts to the work area. The work area is the area where the user holds the delivery liquid container 503 in the equipment holding part and / or the user removes the delivery liquid container 503 held in the equipment holding part. In addition, the equipment conveying part can use the user's motion detection or the user's conveying instruction as a basis to transport other equipment holding parts to replace the equipment holding parts located in the work area. In addition, in this modified example, the delivery liquid container 503 is an example of a mixing injection device used for mixing injection. [Composition of the Printing / Reviewing Unit] Figure 24 is a perspective view showing an example of the overall composition of the printing / reviewing unit 50. Figure 25 is a perspective view of the printing / reviewing unit 50 viewed from the rear side. Figure 26 is a perspective view showing an example of the internal composition of the printing / reviewing unit 50. The metering unit 52 is omitted from Figures 24 and 25. Furthermore, Figure 24 shows an example of the state in which the delivery liquid container 503 is located in the printing / reviewing unit 50 due to adsorption by the second conveying unit 120. As shown in Figures 23 to 25, the printing / review unit 50 includes a printing unit 51, a measuring unit 52, a second reading unit 53, an affixing unit 54, a label supply unit 55, and a pair of guide units 56. Each component of the printing / review unit 50 is controlled by the printing / review unit control unit 148. The printing unit 51 prints a type information label LA1 containing type information indicating the type of medicine obtained by mixing the injection unit 40 with the delivery liquid of the delivery liquid container 503. For example, the printing unit 51 may issue a type information label LA1 with type information printed in barcode form. Furthermore, the printing unit 51 prints an inappropriate information label LA2 containing inappropriate information, which will be described later. As shown in Figure 5, the printing / review unit control unit 148 includes a review unit 1481. The review unit 1481 reviews the delivery liquid container 503 after the drug is injected. In this embodiment, the review unit 1481 determines, based on the measurement results of the measurement unit 52, whether the delivery container 503 after drug injection has been filled with the prescribed amount of drug as indicated in the preparation data. In other words, the review unit 1481 functions as a weight determination unit that determines whether the weight of the delivery container 503 after drug injection is appropriate based on the weight of the delivery container 503 after drug injection measured by the measurement unit 52 and the prescribed amount. For example, the review unit 1481 determines whether the difference between the weight of the delivery container 503 before drug injection and the weight of the delivery container 503 after drug injection is consistent with the prescribed amount of drug as indicated in the preparation data. Furthermore, based on the reading results of the second reading unit 53, the review unit 1481 determines whether to affix a suitable type information label LA1 to the delivery container 503 after drug injection. The review unit 1481 determines whether the drug indicated by the type information contained in the barcode read by the second reading unit 53 is the drug injected into the delivery container 503 whose barcode has been read (whether it is the drug indicated in the preparation data that should be injected into the delivery container 503). When the review unit 1481 determines that the review result is appropriate, the second conveying unit 120 discharges the delivery liquid container 503 after drug injection to the delivery liquid receiving unit 60. On the other hand, when the review unit 1481 determines that the review result is inappropriate, the printing unit 51 prints an inappropriate information label LA2 containing inappropriate information. The inappropriate information label LA2 can also be printed when the weight measured by the measuring unit 52 is inappropriate. That is, the inappropriate information can be information indicating that the weight measured by the measuring unit 52 is inappropriate. However, the inappropriate information label LA2 can also be printed when the reading result of the second reading unit 53 is inappropriate. In this case, the inappropriate information can be information indicating that the reading result of the second reading unit 53 is inappropriate. The unsuitable information label LA2 is printed by the printing unit 51 and can be affixed to the delivery container 503 after the drug has been injected. In this embodiment, the affixing of the unsuitable information label LA2 is performed by the affixing unit 54, but it can also be affixed by the user, for example. In this case, the affixing unit 54 may not be present. The metering unit 52 measures the weight of the delivery liquid container 503 after the drug is injected. In this embodiment, the metering unit 52 also measures the weight of the delivery liquid container 503 before the drug is injected. In this embodiment, as shown in FIG24, the metering unit 52 has a pair of locking portions 521 that lock the head of the delivery liquid container 503. By locking the head of the delivery liquid container 503 in the pair of locking portions 521 by the second conveying unit 120, the metering unit 52 can measure the weight of the delivery liquid container 503. The metering unit 52 is, for example, a load cell. The second reading unit 53 reads the type information label LA1 affixed to the delivery container 503 after the drug has been injected. The second reading unit 53 is, for example, a barcode reader. The affixing unit 54 affixes a type information label LA1 to the delivery container 503 after drug injection. For example, the affixing unit 54 affixes the type information label LA1 to the delivery container 503 after drug injection before the review unit 1481 conducts its review. Then, if the review result obtained by the review unit 1481 is unsuitable, the affixing unit 54 affixes an unsuitable information label LA2 to the delivery container 503 after drug injection. At this time, the affixing unit 54 can also affix the unsuitable information label LA2 to a position that does not overlap with the printed position of the type information contained in the type information label LA1. Therefore, even when the unsuitable information label LA2 is affixed, the user can visually identify the type information. In this embodiment, as shown in FIG25, the attachment part 54 includes an adsorption mechanism 541 and a moving mechanism 542. The type information label LA1 and unsuitable information label LA2 printed by the printing part 51 are discharged to a position above the tray 511, which is set approximately horizontally to the XY plane. The adsorption mechanism 541 adsorbs the type information label LA1 or unsuitable information label LA2 discharged onto the tray 511, allowing the attachment part 54 to retain the type information label LA1 or unsuitable information label LA2. The moving mechanism 542 can move the adsorption mechanism 541 from above the tray 511 to the tray 511, or in the opposite direction (i.e., vertically). Furthermore, the moving mechanism 542 can move the adsorption mechanism 541 between the tray 511 and the attachment position PO1 (see FIG26) where the type information label LA1 or unsuitable information label LA2 is attached to the delivery liquid container 503 after drug injection. In this embodiment, the moving mechanism 542 is configured to be able to move vertically and rotate in the YZ plane. In this way, the attachment part 54 can attach the type information label LA1 or the unsuitable information label LA2 held on the tray 511 to the delivery container 503 after the drug is injected at the attachment position PO1. The adsorption mechanism 541 removes the adsorption of the type information label LA1 or the unsuitable information label LA2 at the attachment position PO1. Furthermore, as shown in Figure 26, when the attachment part 54 attaches the type information label LA1 or the unsuitable information label LA2 to the delivery container 503 after drug injection, the pair of guide parts 56 guide the movement of the type information label LA1 or the unsuitable information label LA2 toward the delivery container 503 after drug injection. Specifically, the pair of guide parts 56 are configured to swing in the XY plane. Therefore, when the second conveying part 120 pushes the delivery container 503 after drug injection toward the type information label LA1 or the unsuitable information label LA2 located at the attachment position PO1, the pair of guide parts 56 swing in the XY plane. In addition, springs 561 are provided at both ends of the pair of guide parts 56. Therefore, when the second conveying part 120 pushes the delivery container 503 after drug injection toward the type information label LA1 or the unsuitable information label LA2 located at the attachment position PO1, the pair of guide parts 56 swing in the YZ plane. By oscillating the pair of guides 56, the attachment part 54 can attach the type information label LA1 or the unsuitable information label LA2 along the shape of the surface of the delivery container 503 after the medication has been injected. Therefore, the type information label LA1 or the unsuitable information label LA2 can be attached to the delivery container 503 after the medication has been injected more reliably. The label supply unit 55 supplies labels to the printing unit 51. The printing unit 51 can then print either type information label LA1 or unsuitable information label LA2. (Processing of the Printing / Review Control Unit) Figure 27 is a flowchart illustrating an example of the processing of the printing / review unit control unit 148. As shown in Figure 27, the second transport control unit 145 transports the pre-injection delivery liquid container 503 from the delivery liquid rack 30 to the metering unit 52 by controlling the second transport unit 120. When the pre-injection delivery liquid container 503 is locked by a pair of locking parts 521, the metering unit 52 measures the weight of the pre-injection delivery liquid container 503 (S401). The review unit 1481 receives the measurement result from the metering unit 52. Next, the second transport control unit 145, by controlling the second transport unit 120, transports the metered medication delivery container 503 to the mixing and injection unit 40. The mixing and injection unit control unit 144 begins the mixing and injection process (S402). Then, the printing / review unit control unit 148, by controlling the printing unit 51, prints the category information label LA1 (S403). In other words, the printing unit 51 begins printing the category information label LA1 before the review unit 1481 outputs its judgment result. In conventional injection devices, the type information label is printed only after the prescribed amount of medication has been injected into the delivery container. However, the printing / review unit 50 begins printing the type information label LA1 without waiting for the review result from the review unit 1481. Therefore, the printing / review unit 50 can affix the type information label LA1 to the delivery container 503 after medication injection much faster than in conventional technology. When the mixing injection unit control unit 144 finishes the mixing injection process (S404), the printing / review unit control unit 148 affixes the type information label LA1 to the delivery container 503 after drug injection by controlling the affixing unit 54 (S405). Then, when the second transport control unit 145 transports the drug-injected delivery liquid container 503 to the metering unit 52 by controlling the second transport unit 120, the metering unit 52 measures the weight of the drug-injected delivery liquid container 503 (S406). The review unit 1481 receives the measurement result from the metering unit 52. Then, the review unit 1481 calculates the difference between the weight of the delivery liquid container 503 before drug injection and the weight of the delivery liquid container 503 after the mixed injection treatment (S407). Next, the review unit 1481 determines whether the difference calculated in S407 is consistent with the prescription amount of the drug injected into the delivery liquid container 503 shown in the preparation data (S408). When the review unit 1481 determines that the difference calculated in S407 matches the prescription amount of the drug shown in the modulation data (YES in S408), the second reading unit 53 reads the barcode of the type information label LA1. Then, the review unit 1481 determines whether the type of drug injected in the mixed injection process matches the type of drug in the prescription (S409). The reading process performed by the second reading unit 53 can be performed after the type information label LA1 is affixed to the delivery container 503 after drug injection and before the determination in S409. That is, the type information label LA1 can be printed and affixed to the delivery container 503 after drug injection before the reading process performed by the second reading unit 53 is performed. When the review unit 1481 determines that the two agents are of the same type (YES in S409), the second transfer control unit 145 discharges the injected agent into the delivery liquid container 503 to the delivery liquid receiving unit 60 by controlling the second transfer unit 120 (S410). On the other hand, if the review unit 1481 determines that the difference calculated in S407 is inconsistent with the prescription amount of the drug shown in the modulation data (NO in S408), the printing / review unit control unit 148 performs the processing in S411. Furthermore, if the review unit 1481 determines that the type of drug injected in the mixed injection process is inconsistent with the type of drug in the prescription (NO in S409), the printing / review unit control unit 148 performs the processing in S411. In step S411, the printing / review unit control unit 148 prints an unsuitable information label LA2 indicating an unsuitable review result by controlling the printing unit 51. The printing / review unit control unit 148 then affixes the printed unsuitable information label LA2 to the delivery container 503 after drug injection, which already has the type information label LA1 affixed, by controlling the affixing unit 54 (S412). Thus, when the review result is unsuitable, the type information label LA1 is affixed to the delivery container 503 after drug injection, followed by the unsuitable information label LA2, allowing the type information label LA1 to be affixed without waiting for the review result. In other words, the mixing injection device 1 allows the type information label LA1 to be affixed to the delivery container 503 after drug injection before the judgment result obtained by the review unit 1481 is output. Additionally, in S412, the printing / review unit control unit 148 can affix the unsuitable information label LA2 to a position that does not overlap with the printing position of the barcode of the type information label LA1 by controlling the affixing unit 54. (Method for Affixing Type Information Label and Inappropriate Information Label) Figure 28 is a diagram illustrating the method of affixing type information label LA1 and inappropriate information label LA2 to the delivery container 503. Symbol 28001 in Figure 28 indicates a state where a delivery label containing label information is affixed to the main body 5031 of the delivery container 503. Symbol 28002 in Figure 28 indicates a state where type information label LA1 is affixed to the main body 5031 of the delivery container 503. Symbol 28003 in Figure 28 indicates a state where type information label LA1 and inappropriate information label LA2 are affixed to the main body 5031 of the delivery container 503. As shown by symbol 28001 in Figure 28, a delivery fluid label is affixed by the pharmaceutical manufacturer supplying the delivery fluid container 503 to the main body 5031 of the delivery fluid container 503. The label information contains information about the delivery fluid injected into the delivery fluid container by the pharmaceutical manufacturer (e.g., information indicating the type of delivery fluid). The label information may be in barcode form. Furthermore, as label information, information indicating the type of delivery fluid, information about the pharmaceutical manufacturer, the composition of the delivery fluid, its capacity, expiration date, and manufacturing number may be printed on the delivery fluid label, for example, in text form. As shown by symbol 28002 in Figure 28, the attachment part 54 can attach the type information label LA1 in the same direction as the delivery fluid label affixed by the pharmaceutical manufacturer (the direction in which the information about the delivery fluid is printed). In other words, the attachment part 54 can attach the type information label LA1 to the delivery fluid container 503 after drug injection with the upper part of the type information label LA1 facing the bottom side of the delivery fluid container 503 after drug injection. For example, when administering an IV drip, the delivery container 503 is used with its bottom vertically facing upwards. Therefore, by attaching the type information label LA1 as described above, the user can easily read the type information from the type information label LA1 when using the delivery container 503. The category information label LA1 may include textual information such as patient ID, patient name, ward building name, department name, ward name, date of mixed injection, name of infusion fluid, and name of injected medication (an example of category information). Furthermore, the category information label LA1 may also include a barcode BC containing the patient ID and category information. When the category information label LA1 is affixed to the infusion container 503, the barcode BC is printed approximately parallel to the length of the infusion container 503 (approximately perpendicular to the bottom). This reduces distortion of the barcode BC caused by the curvature of the infusion container 503, thus improving the reading accuracy of the barcode BC. Furthermore, the measurement results from the measurement unit 52 are not printed on the category information label LA1. This allows the category information label LA1 to be affixed to the delivery container 503 before reviewing the measurement results based on the measurement unit 52. Therefore, review time can be shortened. As shown by symbol 28003 in Figure 28, the affixing part 54 can affix an unsuitable information label LA2 in a position that does not overlap with the printed position of the category information contained in the category information label LA1, in a manner that allows the user to visually identify the category information. The unsuitable information label LA2 can be affixed to a position contained in the category information label LA1 that does not overlap with the printed position of information other than the aforementioned category information. In this case, the user can also easily visually identify information other than the category information. Unsuitable information can also be represented by text or symbols, for example. For example, unsuitable information can be an × mark. Furthermore, by attaching the inappropriate information label LA2 in a position offset from the type information label LA1, the user can easily peel off the inappropriate information label LA2. Therefore, for the delivery container 503 containing a drug that the mixing injection device 1 determines is inappropriate but the user determines is usable, the user can easily peel off the inappropriate information label LA2 and use it.
