Description

[Technical Field]

[0001] The present invention relates to a transport device for transporting an object to be transported. [Background technology]

[0002] Relatively heavy products, such as pumps and multifunction machines, that are equipped with casters have been known for some time. Generally, when a product is transported to a predetermined location, it has been conventionally placed on a pallet and transported using a forklift, hand pallet truck (hand lift), or the like (see, for example, Patent Document 1). However, depending on the product, if it is a relatively heavy item, workers may not be able to manually load it onto a pallet, and a separate crane or the like may be required. Furthermore, when transportation is required in an environment where a pallet cannot be used, the product's casters have been used for transportation. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-116550 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the object to be transported is heavy, multiple people must push and pull the object, which requires labor and time, and the transport operation may not be stable. Furthermore, because casters are part of the product, using them before shipping may result in dirt or damage to the casters. Furthermore, when the object to be transported is a precision instrument, there is a problem that the casters of the object may directly apply vibrations to the object depending on the condition of the transport road surface. For example, while it is possible to store the object in a storage box for transport, there are cases during the transport process where the object cannot be stored in the storage box or where it is difficult to spend time on storing the object in the storage box for transport, such as when moving a short distance. For this reason, there has been a demand for a transport device that can stably transport even relatively heavy objects.

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an object to be transported that has casters and can be easily transported. [Means for solving the problem]

[0006] According to one aspect of the present invention, a hand lift includes a base and a pair of arms attached to the base, a top plate fixed between the pair of arms, a pair of rails attached to the top plate with a width greater than the width of a pair of casters aligned in the left-right direction of an object to be transported, and an auxiliary plate attached to the edge of the top plate at the tip end so as to be rotatable between a first position in which the tip is lower than the top plate and a second position in which the tip is higher than the top plate, and which can come into contact with the ground in the first position. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide an object to be transported that has casters and can be easily transported. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] The configuration of a transporting device 1 according to an embodiment of the present invention will be described below with reference to Figs. 1 to 6. Fig. 1 is a perspective view showing the configuration of the transporting device 1 according to an embodiment of the present invention from above, and Fig. 2 is a perspective view showing the configuration of the transporting device 1 from below. Fig. 3 is a plan view showing the configuration of the transporting device 1 with some parts omitted, and Fig. 4 is a side view showing the configuration of the transporting device 1. Fig. 5 is a perspective view showing a state in which an object to be transported 100 is placed and transported as an example of use of the transporting device 1, and Fig. 6 is a perspective view showing a state in which an object to be transported 100 larger than that shown in Fig. 5 is placed and transported as an example of use of the transporting device 1.

[0010] 1 to 6, the transport device 1 includes a hand lift 11, a top plate 12, an auxiliary plate 13, rail members 14, side frames 15, a back frame 16, reinforcing members 17, and fixing members 18. The transport device 1 transports a relatively heavy object 100 having casters 100a. In the following description, the front-to-rear direction is defined by defining the side of a handle 24 (described later) of the transport device 1 (hand lift 11) as the rear side, and the tip side of a pair of arms 21b of a fork 21 (described later) as the front side, and the directions perpendicular to the front-to-rear direction and the direction of gravity as the left-to-right direction.

[0011] Here, the object 100 to be transported is, for example, a relatively heavy product such as a pump or a multifunction machine, and is provided with a plurality of casters 100a as indicated by the two-dot chain line in FIG. 3. As shown in FIG. 3, the object 100 to be transported is formed, for example, so as to be movable in at least one direction by the casters 100a. The plurality of casters 100a of the object to be transported 100 are provided, for example, in a line of two or more in the front-to-back direction and the left-to-right direction. For example, as shown in FIG. 3, the plurality of casters 100a are configured by two pairs of casters 100a that are provided side by side in the front-to-back direction, each pair being a pair of casters 100a that are arranged side by side in the left-to-right direction.

[0012] The hand lift 11 is a so-called hand pallet jack or hand fork, and is configured to be manually operable. The hand lift 11 includes a fork 21, a plurality of wheels 22, a jack unit 23, and a handle 24.

[0013] The fork 21 includes a base 21a and a pair of arms 21b. The base 21a is integrally formed with the pair of arms 21b. The pair of arms 21b are spaced apart in the left-right direction perpendicular to the front-rear direction of the hand lift 11. For example, the pair of arms 21b are spaced apart by a distance greater than the left-right width of the object 100 to be transported.

[0014] The plurality of wheels 22 are provided on the base 21a and the pair of arms 21b. Two wheels 22 that are free-wheeling wheels called steering wheels are provided on the base 21a, and one or more wheels 22 that are fixed wheels called road wheels or fork wheels are provided on each of the pair of arms 21b. For example, when the plurality of wheels 22 are provided on each arm 21b, some of the plurality of wheels 22 are arranged side by side in the front-to-rear direction.

[0015] The jack unit 23 is operated to raise and lower the pair of arms 21b. The jack unit 23 includes, for example, a hydraulic pump that increases hydraulic pressure when operated, a cylinder whose piston is moved by the hydraulic pump, a mechanism that raises and lowers the pair of arms 21b by driving the cylinder, a speed reduction mechanism such as a slow valve mechanism or a lowering operation dial that dampens the descent speed of the pair of arms 21b when they are lowered, a hydraulic circuit such as piping and valves for hydraulic oil, and an operation body that operates the hydraulic pump, the speed reduction mechanism, etc. The operation body is an operation dial or an operation lever that reduces the hydraulic pressure of the cylinder. The operation body may also be a handle 24.

[0016] The handle 24 is formed so that it can operate the direction of the wheels 22, which are the steering wheel, and can also operate the fork 21 by pushing and pulling.

[0017] The top plate 12 is fixed between the pair of arms 21b. The top plate 12 is formed in a flat plate shape. The top plate 12 is formed, for example, from a metal material and fixed to the pair of arms 21b by welding. For example, the top plate 12 is continuous between the side surfaces of the pair of arms 21b. For example, the top surface of the top plate 12 is disposed lower than the top surfaces of the pair of arms 21b. Note that the top surface of the top plate 12 may be flush with the top surfaces of the arms 21b.

[0018] The auxiliary plate 13 is provided at the tip opposite the base 21a of the top plate 12. The auxiliary plate 13 is formed so as to be rotatable around the top plate 12 side, and the tip opposite the top plate 12 side is placed on the ground, thereby functioning as a slope that helps the object to be transported 100 to climb onto the top plate 12.

[0019] For example, the auxiliary plate 13 includes a pair of first support parts 13a fixed to the top plate 12 or the pair of arms 21b, a pair of rotation shafts 13b rotatably provided on each of the pair of first support parts 13a, a pair of second support parts 13c to which each rotation shaft 13b is fixed, a pair of plate members 13d fixed to each of the second support parts 13c, and a plurality of connecting bars 13e connecting the pair of plate members 13d. Note that the auxiliary plate 13 may have a configuration including a single plate member, without including the pair of plate members 13d and the plurality of connecting bars 13e.

[0020] The first support portion 13a is formed with a hole 13a1 in which the rotary shaft 13b is rotatable and in which the rotary shaft 13b is movable up and down, and a groove 13a2 formed at the upper end.

[0021] The rotating shaft 13b is fixed to the second support portion 13c. The second support portion 13c is formed with a protrusion 13c1 that engages with the groove 13a2 in the rotational direction of the rotating shaft when the rotating shaft 13b moves downward in the hole 13a1. That is, the second support portion 13c to which the rotating shaft 13b is fixed rotates and moves up and down in response to the rotation and up and down movement of the rotating shaft 13b inserted in the hole 13a1, and is supported by the first support portion 13a so as to be unable to rotate when the rotating shaft 13b moves downward and the protrusion 13c1 engages with the groove 13a2 of the first support portion 13a.

[0022] Each plate 13d is fixed to the second support portion 13c. Casters 100a of the transport object 100 slide on each plate 13d. Each plate 13d has a rotation shaft 13b at one end, and can rotate between a first position where the tip is lower than the top plate 12 and a second position where the tip is higher than the top plate 12. As a specific example, the pair of plate members 13d are formed so as to be rotatable between a first position in contact with the ground as shown in FIG. 4 and a second position in which the plate members 13d stand upright as shown in FIG. 5, and can be fixed in the second position. In the left-right direction of the hand truck 11, the distance between the pair of plate members 13d is smaller than the inner width of the pair of casters 100a aligned in the left-right direction of the transport object 100. In addition, in the left-right direction of the hand truck 11, the distance between the outer edges of the pair of plate members 13d is greater than the outer width of the pair of casters 100a aligned in the left-right direction of the transport object 100. The plurality of connecting bars 13e are fixed to the lower surfaces of the pair of plate materials 13d by welding, for example, so that the pair of plate materials 13d can rotate integrally. The connecting bars 13e are, for example, round or square bars made of a metal material.

[0023] The rail member 14 is provided on, for example, the top plate 12. The rail member 14 includes a pair of rails 31, a stopper rail 32, and a pair of guide rails 33. The rail member 14 guides the movement direction and stopping position of the casters 100a of the transport object 100. For example, the height of the rail member 14 is set to a height that does not interfere with components other than the casters 100a, such as a housing, when the transport object 100 is transported, for example, a height that is lower than the bottom surface of the housing. Furthermore, the pair of rails 31, the stopper rail 32, and the pair of guide rails 33 are formed, for example, from a resin material and fixed with fastening members such as bolts.

[0024] The pair of rails 31 are formed, for example, in the shape of rectangular pillars elongated in one direction and extend in the front-to-rear direction of the hand lift 11. The pair of rails 31 are formed by arranging a plurality of rectangular pillar-shaped members elongated in one direction along the longitudinal direction. The pair of rails 31 are fixed to the upper surface of the tabletop 12 by fastening members such as bolts. One end of the pair of rails 31 is disposed at the tip of the tabletop 12 on the side where the auxiliary plate 13 is provided. The other end of the pair of rails 31 is disposed rearward of the center of the tabletop 12 in the front-to-rear direction and toward the center from the rear end of the tabletop 12. As shown in FIG. 3 , the distance between the pair of rails 31 in the left-to-right direction of the hand lift 11, i.e., the width W1 between the opposing side surfaces of the pair of rails 31, is set to be larger than the outer width W2 of the pair of casters 100a aligned in the left-to-right direction of the transported object 100.

[0025] The stopper rail 32 is a stopper that restricts the movement of the object 100 to the rear of the stopper rail 32 by abutting against a part of the object 100, such as the caster 100a of the object 100 or the side surface of the object 100. In this embodiment, an example will be described in which the stopper rail 32 abuts against the caster 100a of the object 100.

[0026] The stopper rail 32 is formed in the shape of a rectangular pillar that is long in one direction. The stopper rail 32 is fixed to the upper surface of the tabletop 12 by fastening members such as bolts. The stopper rail 32 is provided at a predetermined position on the tabletop 12 in the front-rear direction of the hand lift 11, and its longitudinal direction extends along the left-right direction of the hand lift 11. For example, the stopper rail 32 is set at a position where the center of gravity of the object 100 to be transported is located on the tabletop 12 and the object 100 does not come into contact with the back frame 16 and the base 21a. More preferably, the stopper rail 32 is provided at a position where at least the smallest object 100 to be transported can be placed on the tabletop 12, and where the center of gravity of at least the largest object 100 to be transported can be placed on the tabletop 12. As a specific example, the stopper rail 32 is provided between the center and rear end of the tabletop 12 in the front-rear direction of the hand lift 11. For example, the stopper rail 32 connects the rear ends of the pair of rails 31 on the side opposite to the auxiliary plate 13 side.

[0027] The stopper rails 32 may be formed so that their fixed positions on the tabletop 12 can be changed to match the positions of the casters 100a of the transport object 100 to be transported. In this configuration, the method for fixing the stopper rails 32 is not limited as long as they can be selectively fixed to any position in the front-to-rear direction of the tabletop 12. In addition, if the stopper rails 32 abut against the side surface or the like of the transport object 100 instead of the casters 100a, the height of the stopper rails 32 may be set to the height at which they are desired to abut, and may be set to a height approximately the same as the center position of the height of the transport object, for example.

[0028] The pair of guide rails 33 are provided on a pair of plate materials 13d of the auxiliary plate 13. The guide rails 33 are formed as rectangular pillars elongated in one direction. The pair of guide rails 33 are fixed to the upper surfaces of the pair of plate materials 13d by fastening members such as bolts. The distance between the pair of guide rails 33, i.e., the width between the opposing side surfaces of the pair of guide rails 33, is greater than the outer width W2 of the pair of casters 100a of the transport object 100, and the front ends of the pair of plate materials 13d are wider than the top panel 12 sides of the pair of plate materials 13d. As a specific example, the distance between the pair of guide rails 33 is wider at the front ends than at the rear ends, and the distance between the rear ends of the pair of guide rails 33 is formed to be the same as the distance between the pair of rails 31. Furthermore, the rear ends of the pair of guide rails 33 are formed in a position or shape that does not interfere with the pair of rails 31 when the pair of plate materials 13d is in the second posture. Such a pair of guide rails 33 are arranged at an angle relative to the front-to-rear direction of the hand lift 11 so that the width gradually decreases from the tip end of the pair of plate materials 13d toward the top plate 12, thereby guiding the object to be transported 100 into the pair of rails 31.

[0029] The side frames 15 are formed of a metal material and are respectively attached to the upper surfaces of the pair of arms 21b. The side frames 15 are erected in the direction of gravity from the upper surfaces of the pair of arms 21b. For example, of the two side frames 15, one side frame 15A is formed in a rectangular plate shape, and the other side frame 15B is formed in a rectangular frame shape. The shape of the side frames 15 can be appropriately set as long as it is a configuration that allows the fixing member 18 to be fixed. For example, the side frame 15A is formed in a chamfered shape with an inclined upper end toward the tip of the arm 21b. The side frames 15 are also fixed to the upper surfaces of the pair of arms 21b by welding or the like. For example, a plurality of reinforcing plates 15a are provided at corners between the side surface of the side frame 15A facing the side frame 15B and the upper surface of the arm 21b. The reinforcing plates 15a are fixed to the inner surface of the side frame 15 and the upper surface of the arm 21b by welding. The reinforcing plates 15a can improve the welding strength of the side frame 15 and the bending strength of the side frame 15 in the opposing direction of the pair of side frames 15.

[0030] The back frame 16 is made of a metal material and is provided on the top plate 12 or the end of the pair of arms 21b opposite the auxiliary plate 13, or on the base 21a. The back frame 16 is a so-called gate-shaped frame and is formed in a rectangular frame shape. For example, the back frame 16 has a vertical frame 16a extending in the direction of gravity that is formed in an L-shaped cross section and protrudes in the left-right and rearward directions like a plate.

[0031] The reinforcing member 17 is integrally fixed between the underside of the top plate 12 and the arm 21b by welding or the like. As shown in Fig. 2, the reinforcing member 17 is formed in a lattice shape by combining a plurality of reinforcing members 17a extending in the front-rear direction of the hand truck 11 and reinforcing members 17b extending in the left-right direction. For example, the reinforcing members 17a of the reinforcing member 17 extending in the front-rear direction of the hand truck 11 are arranged in an area where the casters 100a of the transport object 100 that is expected to be transported are arranged.

[0032] 5 and 6, the fixing member 18 holds the object to be transported 100 and fixes it on the top board 12. For example, the fixing member 18 is formed in a belt shape and is formed so that both ends can be fixed to the pair of side frames 15 and / or the back frame 16. For example, the fixing member 18 includes a winding device 18a, a belt-shaped belt 18b that can be wound, fixed, and fed by the winding device 18a, a first fixing means for fixing the winding device 18a, and a second fixing means provided at the tip of the belt 18b for fixing the belt 18b. For example, such a fixing member 18 is, for example, a reel lock.

[0033] For example, the first fastening means is a magnet that can selectively fasten the reeling device 18a to one of the side frames 15 and the back frame 16. The second fastening means is a hook, a carabiner, or the like that can fasten the tip of the belt 18b to the other of the side frames 15B and the vertical frame 16a of the back frame 16. For example, the fastening member 18 fastens the reeling device 18a to one of the side frames 15A or one of the vertical frames 16a of the back frame 16 by the first fastening means, and then, with the belt 18b routed around the outer surface of the object 100 on the tabletop 12, fastens the second fastening means to the other side frame 15B or the other vertical frame 16a, thereby restraining the object 100 and fixing it on the tabletop 12. Note that in the example of this embodiment, two fastening members 18 are used, so that the object 100 is restrained in the front-to-back direction, the left-to-right direction, and the up-and-down direction and fixed on the tabletop 12.

[0034] According to the conveying device 1 configured in this manner, the object 100 to be transported can be moved onto the top plate 12 and fixed on the top plate 12 with the fixing member 18, thereby allowing the conveying device 1 to transport the object 100.

[0035] An example of transporting an object 100 using the transport device 1 will be described with reference to Fig. 5. In the example of Fig. 5, an example of transporting an object 100 using the transport device 1 will be described using an object 100 of a size that can be placed on the top board 12.

[0036] First, the jack unit 23 of the transport device 1 is operated to move the pair of arms 21b to the lowest position, and the plate material 13d of the auxiliary plate 13 is set to the first posture. As a result, the tip of the plate material 13d comes into contact with the ground, and the auxiliary plate 13 is connected from the ground to the top plate 12. Next, the object 100 to be transported is pushed to place the object 100 on the top plate 12. At this time, even if the object 100 to be transported is misaligned in the left-right direction from between the pair of rails 31, the pair of guide rails 33 gradually decrease in width from the tip side of the pair of plate materials 13d toward the top plate 12, and thus the pair of guide rails 33 abut against the casters 100a of the object 100 to guide the object 100 so that the casters 100a of the object 100 move into the pair of rails 31. After the transportation object 100 is placed on the top plate 12, the pair of plate materials 13d are rotated from the first position to the second position, and the rotation shaft 13b is moved downward along the hole 13a1, so that the protrusion 13c1 of the second support part 13c is positioned in the groove 13a2 of the first support part 13a. As a result, the pair of plate materials 13d are fixed in the second position.

[0037] Next, the object 100 is restrained in the front-to-rear, left-to-right, and up-to-down directions using the fixing members 18. As a specific example, the reeling device 18a of one fixing member 18 is fixed to one of the vertical frames 16a using the first fixing means. Next, the belt 18b is fed from the reeling device 18a and positioned on one side, the front, and the other side of the object 100, and the second fixing means is fixed to the other vertical frame 16a. With a predetermined tension applied to the belt 18b, the belt 18b is fixed by the reeling device 18a. As a result, the object 100 is pressed rearward in the front-to-rear direction by the fixing member 18, and the caster 100a abuts against the stopper rail 32, restricting the movement of the caster 100a (the object 100), and is thus restrained in the front-to-rear direction. Furthermore, the reeling device 18a of the other fixing member 18 is fixed to one of the side frames 15A using the first fixing means. Next, belt 18b is let out from reel-up device 18a and placed on the upper surface side of transport object 100, and the second fastening means is fixed to the other side frame 15B, and belt 18b is fixed by reel-up device 18a in a state where a predetermined tension is applied to belt 18b. As a result, transport object 100 is restrained in the left-right and up-down directions.

[0038] In this way, the object 100 to be transported is fixed on the top board 12 by being restrained in the front-to-back, left-to-right, and up-to-down directions by the fixing members 18. Note that the object 100 to be transported may be configured to be restrained only in the front-to-back direction by the fixing members 18 fixed to the back frame 16, or may be configured to be restrained only in the left-to-right and up-to-down directions by the fixing members 18 fixed to the pair of side frames 15, for example.

[0039] Next, the jack unit 23 of the transport device 1 is operated to raise the pair of arms 21b. This makes it possible to transport the transport object 100 by operating the handle 24. After transport, the jack unit 23 is operated to lower the pair of arms 21b, and the auxiliary plate 13, which is in the second position, is set to the first position, and the restraint of the fixing member 18 is released, so that the transport object 100 can be lowered from the transport device 1.

[0040] For example, when the object 100 to be transported is placed on the top plate 12, if the center of gravity of the object 100 to be transported is on the top plate 12 but the size of the object 100 is such that a portion of the object protrudes outward from the tip of the top plate 12, then, as shown in Figure 6, the pair of plate members 13d of the auxiliary plate 13 can be left in the first position and the object 100 to be transported can be restrained and fixed to the top plate 12 with the fixing member 18.

[0041] Furthermore, if the casters 100 a of the transport object 100 are provided with a locking mechanism that restricts the rotation of the casters 100 a, the transport object 100 may not be restrained by the fixing members 18 .

[0042] According to the transport device 1 configured in this manner, the top plate 12 is provided between the pair of arms 21b, and the object 100 to be transported is fixed to the top plate 12, thereby making it possible to easily transport the object 100 by utilizing the functions of the hand lift 11. Furthermore, since the object 100 is loaded onto the transport device 1 by moving it to the top plate 12 using the casters 100a of the object 100, there is no need to lift the object 100 or use a pallet, making it easy to transport the object 100. Furthermore, since the transport device 1 can be self-propelled using the wheels 22 of the hand lift 11, the object 100 only needs to be moved a short distance, and damage to the casters 100a of the object 100 can be suppressed.

[0043] Furthermore, the transporting device 1 is provided with fixing members 18 on the pair of side frames 15 and the back frame 16, and restrains the object 100 in the front-to-back, left-to-right, and top-to-bottom directions, thereby preventing the object 100 from moving when being transported. This prevents the object 100 from colliding with the components of the transporting device 1, tipping over, or falling off the transporting device 1, which may be caused by the object 100 moving when being transported. In this way, by using the transporting device 1, it is possible to prevent impacts from being applied to the object 100 when being transported, and therefore it is possible to prevent damage to the object 100 even when the object 100 is a precision machine.

[0044] Furthermore, since the plate material 13d of the auxiliary plate 13 can be set to the first position and the second position, it is possible to transport both the object 100 that can be placed on the top plate 12 and the object 100 that is so sized that a portion of it protrudes forward from the top plate 12. Furthermore, by setting the plate material 13d to the second position, the overall length of the transport device 1 in the front-to-rear direction during transport can be shortened, allowing for tight turning, and even in the unlikely event that the restraint of the fixing member 18 is released, the plate material 13d functions as a stopper, preventing the object 100 from falling off.

[0045] Furthermore, by positioning the upper surface of the tabletop 12 below the upper surfaces of the pair of arms 21b, even if the casters 100a of the object to be transported 100 come off the pair of rails 31, the pair of arms 21b will come into contact with the casters 100a of the object to be transported 100, preventing the object to be transported 100 from falling. Furthermore, by providing reinforcing members 17 on the underside of the tabletop 12 at least in the area where the casters 100a of the object to be transported 100 are arranged, the transport device 1 can prevent deformation of the tabletop 12.

[0046] Furthermore, by providing the plate material 13d with a pair of guide rails 33, the transport object 100 can be guided between the pair of rails 31, making it easy to place the transport object 100 on the top board 12.

[0047] Furthermore, because the pair of rails 31, the stopper rails 32, and the pair of guide rails 33 are made of a resin material, damage to the transport object 100 can be suppressed when they come into contact with the transport object 100. Furthermore, because the pair of rails 31, the stopper rails 32, and the pair of guide rails 33 are configured to be fixed to the top plate 12 and the auxiliary plate 13 with fastening members, when the pair of rails 31, the stopper rails 32, and the pair of guide rails 33 made of a resin material become worn, the pair of rails 31, the stopper rails 32, and the pair of guide rails 33 can be replaced.

[0048] Furthermore, if the transport object 100 is a precision instrument, a speed reducing mechanism can be provided in the jack unit 23 to reduce the impact applied to the precision instrument when the pair of arms 21b descends.

[0049] Furthermore, by using a reel lock as the fixing member 18, it is possible to restrain objects 100 of different sizes, and the restraining position and number can be changed depending on the size and shape, so the conveying device 1 has a high degree of freedom.

[0050] Furthermore, the transport device 1 can use a commercially available hand lift 11, and the transportable object 100 can be appropriately set depending on the size of the hand lift 11, the arrangement and shape of the rail member 14, etc., which makes it possible to reduce manufacturing costs.

[0051] As described above, according to the transport device 1 according to the embodiment of the present invention, it is possible to easily transport the object 100 having the casters 100a.

[0052] The present invention is not limited to the above-described embodiments, and various modifications can be made in the implementation stage without departing from the spirit of the invention. Furthermore, the embodiments may be implemented in appropriate combinations, in which case the combined effects can be obtained. Furthermore, the above-described embodiments include various inventions, and various inventions can be extracted by combining selected elements from the disclosed elements. For example, if the problem can be solved and the desired effect can be obtained even if some elements are deleted from all elements shown in the embodiments, the configuration from which these elements are deleted can be extracted as an invention.
