Description

Technical Field

[0001] The present invention relates to a cleaning and disinfection device for cleaning and disinfecting an endoscope or the like, and a chemical solution bottle unit applied to the cleaning and disinfection device.

Background Art

[0002] Conventionally, medical endoscopes have been widely used for examinations and treatments inside the body. After use, the endoscope needs to be cleaned and disinfected for the next use. For this reason, a cleaning and disinfection device (endoscope reprocessor) for cleaning and disinfecting the endoscope or the like after use has been put into practical use.

[0003] Generally, chemical solutions such as disinfecting solutions used in cleaning and disinfection devices are supplied to the market in a state enclosed in a chemical solution bottle unit. As the chemical solution bottle unit, a configuration in which two chemical solution bottles storing different drugs are integrated is widely adopted.

[0004] Regarding the configuration for supplying the chemical solution in such a chemical solution bottle unit to the cleaning and disinfection device, various proposals have been made in, for example, Japanese Patent No. 4823537 and Japanese Patent No. 5106557.

[0005] The cleaning and disinfection devices disclosed by Japanese Patent No. 4823537, Japanese Patent No. 5106557, etc. have, for example, a configuration that can open the lid (plug) of the chemical solution bottle unit and inject each chemical solution in the chemical solution bottle unit into the cleaning and disinfection device only by performing a closing operation on the tray on which the chemical solution bottle unit is installed.

[0006] In this case, the user first places the liquid medicine bottle unit, filled with the liquid medicine, into a predetermined position on a tray pulled out from the front panel of the cleaning and disinfecting device. Next, the user pushes the tray back into the device to close it. Inside the device, there is a mechanism for breaking open the lid of the liquid medicine bottle unit, such as a blade with a pointed tip. The blade is positioned opposite the lid of the liquid medicine bottle unit placed on the tray, and as the tray moves in the closing direction together with the liquid medicine bottle unit, the lid of the liquid medicine bottle unit comes into contact with the blade.

[0007] As a result, the blade breaks the lid and opens the chemical solution bottle unit. Once the chemical solution bottle is opened, the chemical solutions inside the chemical solution bottle unit are injected into predetermined pathways within the cleaning and disinfecting device.

[0008] Incidentally, the amount of liquid medicine stored in each liquid medicine bottle of a liquid medicine bottle unit may differ from one another. In such cases, each liquid medicine bottle is formed with a different shape. For example, each liquid medicine bottle is formed with a different length in the direction of insertion into the tray.

[0009] In this case, the lids of each liquid medicine bottle are positioned at different locations relative to each other in the direction of insertion into the tray. Consequently, the blades for opening each liquid medicine bottle are also positioned at different locations relative to each other in the direction of insertion into the tray. Therefore, if two liquid medicine bottles are placed in the tray in reverse, there is a risk that the two liquid medicine bottles may not be opened correctly, such as one bottle opening while the other remains closed.

[0010] This invention has been made in view of the above circumstances, and aims to provide a washing and disinfection device and a liquid medicine bottle unit that can properly open two liquid medicine bottles. [Disclosure of the Invention] [Means for solving the problem]

Best Mode for Carrying Out the Invention

[0014] Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 15. It should be noted that in the following description, the drawings based on each embodiment are schematic, and it should be noted that the relationship between the thickness and width of each part, the ratio of the thickness of each part, etc. are different from the actual ones, and there may be parts where the dimensional relationship and ratio are different between the drawings.

[0015] In the following description, the downward direction indicates the gravitational direction (vertically downward), and the upward direction indicates the direction opposite to the gravitational direction (vertically upward). Also, the left - right direction is the horizontal direction orthogonal to the vertical direction.

[0016] Here, as a cleaning and disinfection device, an endoscope cleaning and disinfection device 1, which is an endoscope reprocessor (Automatic Endoscope Reprocessor / AER) shown in FIGS. 1 and 2, is exemplified. The present embodiment described below is a technology applicable not only to endoscopes but also to various forms of cleaning and disinfection devices.

[0017] The endoscope cleaning and disinfection device 1 is a device for performing regeneration processing on a contaminated used endoscope, parts of the endoscope, accessories, etc. (none of which are shown).

[0018] The regeneration processing here is not particularly limited, and for example, it refers to rinsing with water, cleaning to remove dirt such as organic substances, disinfection to inactivate predetermined microorganisms, and sterilization to eliminate or kill all microorganisms. The endoscope cleaning and disinfection device 1 may also perform the above - mentioned various processes in combination.

[0019] Accessories are not particularly limited and may include, for example, a suction button, an air / water supply button, or a tip cover that covers the tip of the endoscope, which are attached to the endoscope during use and removed from the endoscope during reprocessing.

[0020] First, the configuration of the endoscope cleaning and disinfection device 1 will be explained. The endoscope cleaning and disinfection device 1 has a device body 2. The device body 2 has an operation panel 3, an ID input unit 4, a top cover 5, and a water supply hose connection port 6. Furthermore, the device body 2 has a chemical solution bottle mounting device 8 inside for mounting a chemical solution bottle unit 7.

[0021] The control panel 3 is primarily composed of, for example, a touch panel. This control panel 3 can display various types of information. For example, the control panel 3 can display various operation buttons. This allows users to input various instructions to the control panel 3. When an instruction is input by a user, the control panel 3 outputs a signal corresponding to the instruction to the control unit (not shown). Note that the form of the control panel 3 is not limited to the form shown in Figures 1 and 2, and may be formed, for example, by an LED panel and a keyboard with key input capabilities.

[0022] The ID input unit 4 allows input of a user ID. The ID input unit 4 is composed of, for example, an RFID reader capable of reading a user ID from an RFID tag. When a user ID is input, the ID input unit 4 outputs the user ID to the control unit.

[0023] Furthermore, the ID input unit 4 is not limited to an RFID reader; for example, it may be a barcode reader that reads barcodes or a keyboard that allows key input.

[0024] The top cover 5 is provided on the top of the main body 2 of the device so as to be openable and closable. When this top cover 5 is opened, a processing tank (not shown here) is exposed on the top of the main body 2 of the device. The processing tank is a cleaning and disinfecting tank that houses the endoscope and accessories to be reconditioned and stores liquids such as cleaning solution, disinfectant solution, and rinsing solution.

[0025] The water supply hose connection port 6 is located in one corner of the main body 2 of the device. This connection port 6 is connected to a water tap via a water supply hose (not shown).

[0026] As shown in Figures 3 and 4, the liquid medicine bottle unit 7 is a so-called cassette type in which a first liquid medicine bottle 11 and a second liquid medicine bottle 12, which are two types of liquid medicine bottles, are arranged side by side.

[0027] The first liquid medicine bottle 11 contains, for example, the main agent, which is concentrated peracetic acid, as a disinfectant. The second liquid medicine bottle 12 contains, for example, a buffering agent.

[0028] In other words, the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are liquid medicine containers in which different drugs, namely the main drug or a buffering agent, are stored.

[0029] As shown in Figures 3 and 4, the first liquid medicine bottle 11 has a first container body 13, which is the first bottle body, and a first lid 15. The second liquid medicine bottle 12 has a second container body 14, which is the second bottle body, and a second lid 16. The basic shapes of the first and second container bodies 13 and 14 are, for example, rectangular parallelepipeds.

[0030] The first container body 13 has a first opening 13a for discharging the liquid medicine stored in the first container body 13. The first opening 13a is provided at the tip, which is the first end of the first container body 13. In this embodiment, the first opening 13a has a substantially cylindrical shape. Here, in this embodiment, the first end of the first container body 13 coincides with one end of the first container body 13 in the direction of the central axis X1. Furthermore, the direction of the central axis X1 coincides with the insertion direction when inserting the liquid medicine bottle unit 7 into the device body 2 using the liquid medicine bottle mounting device 8.

[0031] Furthermore, the second container body 14 has a second opening 14a for discharging the liquid medicine stored in the second container body 14. The second opening 14a is provided at the tip, which is the first end of the second container body 14. In this embodiment, the second opening 14a has a substantially cylindrical shape. Here, in this embodiment, the first end of the second container body 14 coincides with one end of the second container body 14 in the direction of the central axis X2. Furthermore, the direction of the central axis X2 coincides with the insertion direction when inserting the liquid medicine bottle unit 7 into the device body 2 using the liquid medicine bottle mounting device 8.

[0032] The basic shapes of the first and second lids 15 and 16 are, for example, cylindrical. The first lid 15 is attached to the first opening 13a. The second lid 16 is attached to the second opening 14a. The first lid 15 and the second lid 16 are attached to the first opening 13a and the second opening 14a by screwing or other means.

[0033] The first lid 15 has a first stopper 17 inside. The first stopper 17 is, for example, roughly disc-shaped. The first stopper 17 is integrally formed with the first lid 15 so as to seal the inner hole of the first lid 15. As a result, the first stopper 17 seals the first opening 13a of the first container body 13 in an airtight and liquid-tight state.

[0034] The second lid 16 has a second stopper 18 inside. The second stopper 18 is, for example, roughly disc-shaped. This second stopper 18 is integrally formed with the second lid 16 so as to seal the inner hole of the second lid 16. As a result, the second stopper 18 seals the second opening 14a of the second container body 14 in an airtight and liquid-tight state.

[0035] Here, as shown in Figure 4, the length L1 from the base end, which is the second end of the first container body 13, to the tip (first end) of the first opening 13a is set to be shorter than the length L2 from the base end, which is the second end of the second container body 14, to the tip (first end) of the second opening 14a.

[0036] On the other hand, the first lid 15 and the second lid 16 are identical in shape. Therefore, the length L3 from the base to the tip of the first liquid medicine bottle 11 is set to be shorter than the length L4 from the base to the tip of the second liquid medicine bottle 12.

[0037] Furthermore, the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are joined together such that the base end of the first container body 13 and the base end of the second container body 14 coincide. In other words, the base end surface of the first container body 13 and the base end surface of the second container body 14 are located on the same plane.

[0038] By configuring the liquid medicine bottle unit 7 in this way, the second stopper 18 of the second liquid medicine bottle 12 is positioned further forward than the first stopper 17 of the first liquid medicine bottle 11. That is, the second stopper 18 is positioned offset from the first stopper 17 in the direction that penetrates the first opening 13a (in the direction of the central axis X1 of the first liquid medicine bottle 11). More specifically, the second stopper 18 is positioned further forward than the first stopper 17 in the direction of the central axis X1 of the first liquid medicine bottle 11.

[0039] Such a drug solution bottle unit 7 is replaceable with the main unit 2 of the device. That is, the drug solution bottle unit 7 used for the regeneration process of an endoscope, for example, is removed from the main unit 2 when the next regeneration process is performed. Then, a new drug solution bottle unit 7 is inserted into the main unit 2 of the device.

[0040] The liquid medicine bottle mounting device 8 is a device for removably installing the liquid medicine bottle unit 7 inside the main body 2 of the device. As shown in Figures 1 and 2, the liquid medicine bottle mounting device 8 is positioned inside the main body 2 so as to extend in the front-rear direction of the main body 2. Furthermore, the liquid medicine bottle mounting device 8 is inclined at a predetermined elevation angle such that its base end is higher than its front end. The base end surface of the liquid medicine bottle mounting device 8, positioned in this manner, is exposed to the outside through an opening 2a provided in the front panel of the main body 2 of the device.

[0041] As shown in Figure 5, the drug solution bottle mounting device 8 includes a bottle case 31 and a tray 32.

[0042] The bottle case 31 has a hollow, roughly box-like shape. This bottle case 31 is fixed inside the main body of the device 2. The bottle case 31 also has an opening 31a at its base into which the front part of the drug solution bottle unit 7 can be inserted. Thus, the bottle case 31 functions as a bottle mounting section in which the drug solution bottle unit 7 can be installed inside the main body of the device 2.

[0043] As shown in Figures 6-10, the bottle case 31 has a first lid receiving pipe 43 and a second lid receiving pipe 44 on the lower side of the front end wall 31b. The first and second lid receiving pipes 43 and 44 protrude into the interior of the bottle case 31. Furthermore, the first and second lid receiving pipes 43 and 44 are arranged side by side in the left-right direction of the bottle case 31. The first lid receiving pipe 43 and the second lid receiving pipe 44 are fluid passage inlets that lead the liquid in the first chemical bottle 11 and the second chemical bottle 12 to a chemical tank (not shown).

[0044] As shown in Figure 8, the first lid receiving tube 43 and the second lid receiving tube 44 are cup-shaped so that the first lid 15 of the first liquid medicine bottle 11 and the second lid 16 of the second liquid medicine bottle 12 can be inserted into them when the liquid medicine bottle unit 7 is installed in the bottle case 31.

[0045] Furthermore, outside the bottle case 31, a first fluid conduit 45 and a second fluid conduit 46 are connected to the first lid receiving tube 43 and the second lid receiving tube 44. The first and second fluid conduits 45 and 46 are fluid passages formed in a predetermined curved shape to communicate with the chemical tank. The first lid receiving tube 43 and the second lid receiving tube 44 are integrally equipped with a first blade 41 and a second blade 42 for opening the first stopper 17 and the second stopper 18.

[0046] The first blade 41 corresponds to a specific example of the first opening section, and the second blade 42 corresponds to a specific example of the second opening section. The first and second blades 41 and 42 are tubular metal members, such as stainless steel. The first and second blades 41 and 42 have a sharp shape for piercing and breaking the first and second stoppers 17 and 18 of the first and second lids 15 and 16 that are inserted into the first and second lid receiving tubes 43 and 44. The first blade 41 and the second blade 42 extend from the front end to the base end of the bottle case 31. These first blades 41 and the second blades 42 have different lengths. Furthermore, the first blade 41 and the second blade 42 are arranged in parallel. As a result, in the front-to-back direction of the bottle case 31, the tip of the first blade 41 and the tip of the second blade 42 are set at different positions from each other.

[0047] Furthermore, as shown in Figure 5, the bottle case 31 has a pair of guide rails 33 on the upper part of the left and right walls. Each guide rail 33 extends in the front-to-back direction of the bottle case 31.

[0048] The tray 32 has a bottom plate 35, a back plate 36, and a pair of left and right side plates 37.

[0049] The width of the base plate 35 is set to be slightly larger than the width of the liquid medicine bottle unit 7. This allows the tray 32 to place the liquid medicine bottle unit 7 on it. Furthermore, the width of the base plate 35 is set to be slightly smaller than the width of the opening 31a of the bottle case 31. This allows the tray 32 to be inserted into the inside of the bottle case 31.

[0050] The lower part of the back panel 36 is connected to the base end of the bottom panel 35. This back panel 36 functions as a door that opens and closes the opening 2a of the device body 2. That is, when the tray 32 is inserted to its end position (front position) inside the bottle case 31, the back panel 36 closes the opening 2a of the device body 2 (see Figure 1). At this time, the back of the back panel 36, which is the base end surface of the tray 32, is positioned on approximately the same plane as the front panel of the device body 2. On the other hand, when the tray 32 is retracted backward relative to the bottle case 31, the back panel 36 opens the opening 2a of the device body 2 (see Figure 2).

[0051] The lower parts of the pair of side plates 37 are connected to the left and right sides of the bottom plate 35. Furthermore, the base ends of the pair of side plates 37 are connected to the back plate 36. In this way, the side plates 37 position the liquid medicine bottle unit 7 placed on the tray 32 in the left-right direction.

[0052] Furthermore, the upper ends of the front ends of the pair of side plates 37 are connected to the pair of guide rails 33 in a slidable manner. This allows the tray 32 to move forward and backward relative to the bottle case 31.

[0053] As shown in Figure 6, such a tray 32 is provided with a first storage section 32a capable of accommodating the first liquid medicine bottle 11, and a second storage section 32b capable of accommodating the second liquid medicine bottle 12. These first storage section 32a and second storage section 32b are storage sections for accommodating the first liquid medicine bottle 11 and the second liquid medicine bottle 12, which constitute the liquid medicine bottle unit 7, in the tray 32 in a side-by-side arrangement.

[0054] With the first liquid medicine bottle 11 housed in the first storage section 32a, when the tray 32 is inserted to the first insertion position, the first stopper 17 is destroyed by the first blade 41. That is, when the tray 32 is inserted to the first insertion position, the first lid 15 of the first liquid medicine bottle 11 is opened. Once the first lid 15 is opened, the liquid medicine inside the first liquid medicine bottle 11 is guided to the liquid medicine tank via the first lid receiving tube 43 and the first fluid conduit 45.

[0055] Furthermore, when the tray 32 is inserted to the second insertion position while the second liquid medicine bottle 12 is housed in the second storage section 32b, the second stopper 18 is destroyed by the second blade 42. That is, when the tray 32 is inserted to the second insertion position, the second lid 16 of the second liquid medicine bottle 12 is opened. Once the second lid 16 is opened, the liquid medicine inside the second liquid medicine bottle 12 is guided to the liquid medicine tank via the second lid receiving tube 44 and the second fluid conduit 46.

[0056] In this embodiment, for example, as shown in Figure 8, the first insertion position and the second insertion position are set to the same position. It is also possible to set the first insertion position and the second insertion position to positions offset from each other in the insertion direction.

[0057] In such a liquid medicine bottle mounting device 8, a stopper 50 is provided inside the bottle case 31. In this embodiment, the stopper 50 is provided, for example, on the side plate of the bottle case 31 on the side of the first storage section 32a. This stopper 50 is, for example, a projection that extends in a direction intersecting the insertion direction of the tray 32 (more specifically, in a direction perpendicular to the insertion direction of the tray 32).

[0058] When the first liquid medicine bottle 11 is housed in the first housing section 32a and the second liquid medicine bottle 12 is housed in the second housing section 32b (see Figures 7 and 11), the stopper 50 allows the tray 32 to be inserted to the first and second insertion positions without contacting the liquid medicine bottle unit 7 (see Figures 8 and 12). That is, when the liquid medicine bottle unit 7 is correctly set in the tray 32, the stopper 50 allows the first lid 15 to be opened by the first blade 41 and the second lid 16 to be opened by the second blade 42.

[0059] On the other hand, when the second liquid medicine bottle 12 is housed in the first housing section 32a and the first liquid medicine bottle 11 is housed in the second housing section 32b (see Figures 9 and 13), the stopper 50 comes into contact with the liquid medicine bottle unit 7, preventing the insertion of the tray 32 beyond a predetermined insertion amount. More specifically, the stopper 50 comes into contact with the second liquid medicine bottle 12 (see Figures 10 and 14). As a result, the stopper 50 prevents the tray 32 from being inserted up to the contact point between the first blade 41 and the second stopper 18, and the contact point between the second blade 42 and the first stopper 17. In other words, when the liquid medicine bottle unit 7 is not properly set in the tray 32, the stopper 50 prevents the opening of the second lid 16 by the first blade 41 and the opening of the first lid 15 by the second blade 42.

[0060] In order to achieve the function of the stopper 50 as described above, the mounting position of the stopper 50 on the bottle case 31, the length of the first blade 41, the length of the second blade 42, the mounting position of the first stopper 17 on the first lid 15, and the mounting position of the second stopper 18 on the second lid 16 are all pre-adjusted.

[0061] Here, for example as shown in Figure 11, the side plate 37 on the first storage portion 32a side of the tray 32 is provided with a slit 51 that extends in the direction of insertion of the tray 32. For example as shown in Figure 12, this slit 51 allows the stopper 50 to be inserted through it. This prevents interference between the tray 32 and the stopper 50 when the tray 32 is inserted into the device body 2.

[0062] According to this embodiment, when the first liquid medicine bottle 11 is housed in the first housing section 32a and the second liquid medicine bottle 12 is housed in the second housing section 32b, the stopper 50 allows the tray 32 to be inserted to the first and second insertion positions without contacting the liquid medicine bottle unit 7. As a result, when the liquid medicine bottle unit 7 is correctly set in the tray 32, the insertion of the tray 32 properly opens the first lid 15 and the second lid 16, allowing the liquid medicine in the first liquid medicine bottle 11 and the liquid medicine in the second liquid medicine bottle 12 to be supplied to the liquid medicine tank.

[0063] On the other hand, when the second liquid medicine bottle 12 is housed in the first housing section 32a and the first liquid medicine bottle 11 is housed in the second housing section 32b, the stopper 50 contacts the second liquid medicine bottle 12 just before the contact point between the first blade 41 and the second stopper 18 and just before the contact point between the second blade 42 and the first stopper 17, thereby obstructing the insertion of the tray 32. As a result, if the liquid medicine bottle unit 7 is not properly set in the tray 32, the opening of the first lid 15 and the second lid 16 can be prevented.

[0064] As a result, the first lid 15 and the second lid 16 can be properly opened only when the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are correctly set in the tray 32, and the liquid medicine in the first liquid medicine bottle 11 and the liquid medicine in the second liquid medicine bottle 12 can be reliably supplied to the liquid medicine tank.

[0065] Furthermore, as shown in Figure 15, in a drug solution bottle loading device 8 that does not have a stopper 50, if the first drug solution bottle 11 and the second drug solution bottle 12 are not properly set in the tray 32, cases may occur where only one of the drug solution bottles (for example, the second drug solution bottle 12) is opened.

[0066] Here, for example, as shown in Figure 16, it is possible to set the width of the tip side of the slit 51 to be wider than the width of the base side in the insertion direction of the tray 32. That is, it is possible to form the slit 51 in a tapered shape in which the width of the tip side is set to be wider than the width of the stopper. With this configuration, when moving the tray 32 in the insertion direction, the stopper 50 can be easily inserted through the slit 51.

[0067] Furthermore, the stopper 50 can be positioned in the bottle case 31 in a configuration that allows it to move in a direction intersecting the extending direction of the slit 51. For example, the stopper 50 shown in Figure 16 is positioned in the bottle case 31 in a configuration that allows it to move in the vertical direction. With this configuration, when the tray 32 is moved in the insertion direction, the stopper 50 can be inserted into the slit 51 even more easily.

[0068] Furthermore, as shown in Figure 17, for example, the stopper 50 can be placed on the front end wall 31b of the bottle case 31 instead of the side plate of the bottle case 31. In this case, the direction in which the stopper 50 extends is set to the insertion direction of the tray 32. Even in this configuration, when the liquid medicine bottle unit 7 is not properly set in the tray 32, the stopper 50 can prevent the opening of the second lid 16 by the first blade 41 and the opening of the first lid 15 by the second blade 42.

[0069] Next, a second embodiment of the present invention will be described with reference to Figures 18 and 19. This embodiment includes a configuration for defining the orientation when the liquid medicine bottle unit 7 is placed in the tray 32. Other components similar to those in the first embodiment described above will be denoted by the same reference numerals as appropriate and their descriptions will be omitted.

[0070] The tray 32 of this embodiment has, for example, a keyway 55 which is a recess in the side plate 37 on the second storage section 32b side. This keyway 55 is open at the upper end of the side plate 37 and extends in the vertical direction of the side plate 37.

[0071] Furthermore, the liquid medicine bottle unit 7 has, for example, a key 56 which is a protrusion integrally formed on the second liquid medicine bottle 12. This key 56 can be fitted into the keyway 55 when the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are in a specific arrangement.

[0072] Specifically, when the arrangement of the first liquid medicine bottle 11 and the second liquid medicine bottle 12 matches the arrangement of the first storage section 32a and the second storage section 32b of the tray 32, the key 56 can be fitted into the keyway 55. The key 56 allows the first liquid medicine bottle 11 and the second liquid medicine bottle 12 to be placed in the tray 32 only when it is fitted into the keyway 55 (see Figure 18).

[0073] In other words, for example, as shown in Figure 19, if the arrangement of the first liquid medicine bottle 11 and the second liquid medicine bottle 12 is the opposite of the arrangement of the first storage section 32a and the second storage section 32b, the key 56 will not engage with the keyway 55. Therefore, the key 56 prevents the first liquid medicine bottle 11 and the second liquid medicine bottle 12 from being placed in the tray 32.

[0074] With this configuration, if the liquid medicine bottle unit 7 is not properly set in the tray 32, insertion of the liquid medicine bottle unit 7 into the device body 2 is prohibited. As a result, in this embodiment as well, if the liquid medicine bottle unit 7 is not properly set in the tray 32, opening of the first lid 15 and the second lid 16 can be prohibited.

[0075] Here, for example, as shown in Figures 20 and 21, it is also possible to provide a key 57, which is a protrusion, on the tray 32 and a key groove 58, which is a recess, on the liquid medicine bottle unit 7. Even with such a configuration, the same effects as in the above-described embodiment can be achieved.

[0076] The present invention is not limited to the embodiments and modifications described above, and various modifications and applications can be implemented without departing from the spirit of the invention. Furthermore, each of the embodiments described above includes inventions at various stages, and various inventions can be extracted by appropriate combinations of the multiple constituent elements disclosed. For example, if the problem that the invention aims to solve can be solved and the effects of the invention can be obtained even if some constituent elements are deleted from all the constituent elements shown in one embodiment, then the configuration with these constituent elements deleted can be extracted as an invention. Furthermore, constituent elements from different embodiments and modifications can be appropriately combined.
