Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when implanting hair materials on a hair implanting net to form a general-purpose wig, in order to make a more natural general-purpose wig, it is necessary to adjust the density of the hair materials according to the部位. However, the hair implanting device of Patent Document 1 has a problem that it can only implant at the same density uniformly and cannot adjust the density.

[0005] Therefore, an object of the present invention is to provide a hair implanting device capable of easily adjusting the amount of hair materials implanted per unit area of the hair implanting net.

Means for Solving the Problems

[0006] In order to solve the above-mentioned problems, the inventors conducted diligent research and discovered that the density of hair material in the hair implantation section is determined by the number of hair strands pulled out from the hair material storage section by the pull-out hook section. In other words, they discovered that the density of hair material can be controlled by using a pull-out hook section with a large hook to increase the density of hair material implanted in the hair implantation net, and by using a pull-out hook section with a small hook to decrease the density of hair material implanted in the hair implantation net. Based on this discovery, the inventors hypothesized that if multiple types of pull-out hooks with different hook sizes could be switched between, the density of the hair material could be adjusted to a desired range, enabling the manufacture of more natural-looking, versatile wigs.

[0007] One aspect of the present invention derived from the above considerations is a hair implantation device comprising: a net transport unit for transporting a hair implantation net; a hair material storage unit for storing multiple hair materials; a pull-out means for pulling out the hair materials from the hair material storage unit; and a hair implantation needle unit for attaching a portion of the intermediate part of the hair materials pulled out by the pull-out means to the hair implantation net and implanting the hair, wherein the pull-out means comprises a plurality of types of hooked needle units having hooks that can engage with the intermediate part of the hair materials in the hair material storage unit, and a switching mechanism that can switch between the hooked needle units for pulling out the hair materials from the hair material storage unit, and among the plurality of types of hooked needle units, there is a first hooked needle unit and a second hooked needle unit having a hook that can engage with a larger number of hair materials than the hook of the first hooked needle unit.

[0008] According to this method, the number of hair materials implanted onto the hair implantation net during the hair implantation process can be adjusted by the type of hook used, and the amount (density) of hair materials per unit area can be easily adjusted.

[0009] A preferred configuration is such that the pulling means is capable of pulling out the hair material from the hair material storage section by a hook portion among the plurality of types of hook portions that is positioned in a pull-out position, the switching mechanism has a plurality of holding portions that hold the plurality of types of hook portions, and the positions of the plurality of holding portions can be moved, and the switching mechanism moves the hook portion to be pulled out from the hair material storage section to the pull-out position by moving the holding portions.

[0010] A preferred configuration includes a rotating part that can rotate around a rotation axis, the plurality of holding parts are provided on the rotating part and are spaced apart in the circumferential direction around the rotation axis, and the switching mechanism rotates the rotating part to move the hook part to be pulled out from within the hair material storage part to the pull-out position.

[0011] A preferred configuration is one in which the multiple holding portions are arranged such that the multiple types of hook portions extend in the same direction.

[0012] A preferred configuration is one in which the plurality of holding parts are arranged such that the plurality of types of hook parts extend radially in the direction of the rotating part.

[0013] A preferred configuration includes a transport unit for transporting the plurality of holding units, wherein the plurality of holding units are arranged at intervals in the transport direction of the transport unit, and the switching mechanism moves the hook portion to be pulled out from within the hair material storage unit to the pull-out position as the transport unit transports the holding units.

[0014] A preferred configuration is such that the pulling means can pull out the hair material from the hair material storage section using a hook portion among the plurality of types of hook portions that is positioned at the pull-out position, and the switching mechanism has a holding portion that holds the first hook portion or the second hook portion, and a transport portion that transports the holding portion, and the transport portion can transport the holding portion from a position that is vertically below the pull-out position and horizontally offset from the pull-out position, thereby moving the first hook portion or the second hook portion held by the holding portion to the pull-out position.

[0015] The aspects described above can be dependent on each other, refer to some of their components, or substitute for some of their components, as long as they fall within the technical scope of the present invention. [Effects of the Invention]

Embodiments for Carrying out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail.

[0019] The hair implanting device 1 according to the first embodiment of the present invention is an automatic hair implanting device that automatically implants a hair material 101 into a hair implanting net 100. As shown in FIG. 1, the hair implanting device 1 includes an eccentric part (hereinafter, also simply referred to as an eccentric part 2), a hair implanting barbed needle part 3 (hair implanting needle part), a pulling-out means 5, a hair material supply part 6 (hair material storage part), a guide roll 7, a hair material pulling-in part 8, a hair material dropping part 10, and a conveying roll 11 (net conveying part). The hair implanting device 1 of the present embodiment mainly features the structure of the pulling-out means 5 and the positional relationship between the pulling-out means 5 and the hair material supply part 6. Based on this, the following description will be made.

[0020] (Eccentric part 2) As shown in FIG. 1(b), the eccentric part 2 is an elongated body extending in the axial direction (the width direction of the hair implanting net 100), and includes a main body part 20 and rotating shaft parts 21a and 21b. The eccentric part 2 is a rotational force conversion member in which the rotating shaft parts 21a and 21b are displaced with respect to the central axis of the main body part 20 and convert rotational motion into single vibration, and is a support roll that supports the hair implanting net 100. The eccentric part 2 can change its posture between an opposing posture in which the concave part 22 of the main body part 20 is located on the side of the hair implanting barbed needle part 3 and faces the hair implanting barbed needle part 3, and a vertical posture in which the concave part 22 of the main body part 20 is located on the side of the hair material supply part 6 and faces upward by rotating around the rotating shaft parts 21a and 21b.

[0021] (Hook section with flocked bristles 3) The hair implantation hook section 3 is a hair implantation hook section used to implant hair material 101 into the hair implantation net 100, and has a rod-shaped tip with a claw-like shape.

[0022] (Drawer means 5) The pulling means 5 is a pulling member that pulls the hair material 101 from the hair material supply unit 6 during the hair implantation operation. As shown in Figure 2, the pull-out mechanism 5 is equipped with multiple types of pull-out hook sections 50 (50a to 50c) and a switching mechanism 51, which allows for automatic switching of the pull-out hook section 50 used in the hair implantation operation.

[0023] Each of the pull-out hook sections 50a to 50c is a rod-shaped body with a claw-shaped tip, and as shown in Figures 1 and 2, it is equipped with a needle shaft section 55 and a hook section 56. As shown in Figure 2, each of the pull-out hook sections 50a to 50c differs in at least the size of the hook section 56, and the number of hair materials 101 that can be pulled out from the hair material supply section 6 differs. In other words, as shown in Figure 2, the first pull-out hook section 50a (first hook section) has a smaller hook portion 56 compared to the second pull-out hook section 50b (second hook section), and therefore can pull out fewer strands of hair material 101 from the hair material supply section 6. Also, the second pull-out hook section 50b has a smaller hook portion 56 compared to the third pull-out hook section 50c, and therefore can pull out fewer strands of hair material 101 from the hair material supply section 6.

[0024] The switching mechanism 51, as shown in Figure 2, comprises a rotating part 52, a base part 53, and a drive source (not shown). It is a position adjustment unit that adjusts the position of each pull-out hook part 50a to 50c by driving the drive source to rotate the rotating part 52 relative to the base part 53.

[0025] The rotating part 52 is a rotating body that can rotate circumferentially around the rotation axis L1 relative to the base part 53. The rotating part 52 may be rotatable only in the forward direction (clockwise), or only in the reverse direction (counterclockwise), or it may be rotatable in both the forward and reverse directions. As shown in Figure 2, the rotating part 52 is equipped with housing holes 57a to 57c and a holding part (not shown).

[0026] The storage holes 57a to 57c are provided corresponding to each of the pull-out hook sections 50a to 50c, and are holes capable of individually accommodating part or all of each of the pull-out hook sections 50a to 50c. The housing holes 57a to 57c are arranged at intervals in the circumferential direction around the rotation axis L1 of the rotating part 52.

[0027] The retaining portion is located inside the housing holes 57a to 57c and is the part that holds the base end of each of the pull-out hook portions 50a to 50c. Each holding part is connected to a retractable mechanism, which allows the retractable hook parts 50a to 50c to move automatically in the axial direction of the needle shaft part 55.

[0028] The base portion 53 is the part that connects and supports the rotating portion 52 so that it can rotate relative to it.

[0029] The pull-out means 5 allows each pull-out hook portion 50a to 50c to be individually extended and retracted from the housing holes 57a to 57c of the rotating portion 52 by moving the holding portion described above in the axial direction of the needle shaft portion 55 via the retraction mechanism. In other words, the pulling mechanism 5 is capable of causing the pulling hook portion 50 used for the hair implantation operation to protrude from the housing hole 57 of the rotating portion 52, and housing most or all of the remaining pulling hook portion 50 within the housing hole 57 of the rotating portion 52. In this context, "the majority" refers to more than 50% of the total.

[0030] As shown in Figure 3, the pulling means 5 is positioned in a plan view to coincide with the outlet hole 60 of the hair material supply unit 6, and has a pullable position P1 that corresponds to the planned outlet P2 for the hair material 101 from the outlet hole 60 of the hair material supply unit 6. By positioning the pulling hook part 50 to be used at the pullable position P1, it is possible to pull the hair material 101 out of the outlet hole 60 of the hair material supply unit 6. In other words, the pull-out position P1 is the position in which the pull-out hook portion 50 can be pulled out from the intended removal point P2 of the hair material 101 without being obstructed by the bottom portion 61 of the hair material supply portion 6.

[0031] (Hair material supply section 6) The hair material supply unit 6 is a hair material storage unit that houses the hair material 101 to be implanted into the hair implantation net 100, and is a so-called stocker. As shown in Figure 1, the hair material supply unit 6 has an outlet hole 60 at its bottom 61, allowing the hair material 101, which is housed inside and placed on the bottom 61, to be supplied.

[0032] (Guidance Roll 7) As shown in Figure 1(b), the guide roll 7 has a groove 70 on a part of its outer surface, and a portion of the hair material 101 drawn out from the hair material supply unit 6 by the pull-out hook 50 passes through the groove 70, thereby adjusting the position of the hair material 101 in the width direction to fall within a predetermined range.

[0033] (Hair material intake section 8) The hair material pull-in section 8 is a pull-in bar that pulls the hair material 101, which has been pulled out from the hair material supply section 6 by the pull-out hook section 50, to the downstream side in the transport direction T1 from the hair implantation position of the hair implantation net 100.

[0034] (Hair material insertion section 10) The hair material drop-in section 10 is a drop-in bar that drops the hair material 101, which has been pulled out from the hair material supply section 6 by the pull-out hook section 50, to a position lower than the hair implantation position on the hair implantation net 100.

[0035] (Conveyor roll 11) The conveying roll 11 is a support roll that supports the flocked net 100 so that it passes over the eccentric section 2, and is a net conveying section that conveys the flocked net 100 in the conveying direction T1 by rotating.

[0036] (Hair transplant net 100) As shown in Figure 1, the flocked net 100 is a stretchable net constructed in a mesh-like manner by multiple netting threads 121, and has multiple holes 120.

[0037] (Hair material 101) The hair material 101 is a thread-like structure that is implanted onto the hair implantation net 100. Hair material 101 can be artificial hair made of resin fibers, human hair, animal hair, etc. The hair material 101 of this embodiment is bundled together in multiple pieces and used as a hair bundle.

[0038] Next, the positional relationships of each part of the hair implantation device 1 of this embodiment will be described. Regarding the eccentric section 2, the recess 22 of the main body section 20 shown in Figure 1 is located on the hair implantation hook section 3 side, and the description will be based on the opposing orientation facing the hair implantation hook section 3.

[0039] As shown in Figure 1, the hair flocking device 1 has a hair flocking net 100 suspended from an eccentric section 2 and a transport roll 11. The eccentric section 2 has rotating shafts 21a and 21b pivotally supported, and is capable of rotating in the circumferential direction around the rotating shafts 21a and 21b. The flocked hook portion 3 is in a horizontal position, extending horizontally, with its tip facing the recess 22 of the main body portion 20 in the front-rear direction X.

[0040] As shown in Figure 2, the pull-out mechanism 5 has the hook portion 56 at the tip of each pull-out hook portion 50a to 50c positioned above the needle shaft portion 55, and is in a vertical position extending in the vertical direction. As shown in Figures 2 and 3, the pull-out mechanism 5 has at least one pull-out hook portion 50a to 50c, the hook portion 56 of which faces the outlet hole 60 of the hair material supply portion 6 in the height direction Y (up and down direction). As shown in Figure 3, the rotation axis L1 of the rotating part 52 of the extraction means 5 is offset from the planned extraction point P2 of the hair material 101 from the extraction hole 60 of the hair material supply part 6.

[0041] When performing the hair implantation operation, the pulling means 5 rotates the rotating part 52 around the rotating axis L1 to position the pulling hook part 50 to be used at the pullable position P1, facing the planned extraction point P2 on the exposed portion of the hair material 101 coming out of the extraction hole 60 of the hair material supply unit 6, and houses most or all of the remaining pulling hook part 50 in the storage hole 57.

[0042] For example, when the first pull-out hook section 50a is positioned at the pull-out position P1 as shown in Figure 2(a), and the pull-out mechanism 5 is to change to the second pull-out hook section 50b, the rotating part 52 is rotated circumferentially around the rotation axis L1 as shown by the arrow in Figure 2(a), so that the second pull-out hook section 50b is positioned at the pull-out position P1 as shown in Figure 2(b). In this way, the pull-out hook section 50 that is positioned at the pull-out position P1 and can be used in the hair implantation operation can be switched from the first pull-out hook section 50a to the second pull-out hook section 50b.

[0043] The hair implantation operation of the hair implantation device 1 in this embodiment is the same as in the conventional model, so a description will be omitted.

[0044] According to the first embodiment of the hair implantation device 1, it includes a transport roll 11 for transporting the hair implantation net 100, a hair material supply unit 6 for accommodating a plurality of hair materials 101, a pull-out means 5 for pulling out the hair materials 101 from the hair material supply unit 6, and a hair implantation hook unit 3 for attaching a portion of the intermediate part of the hair material 101 pulled out by the pull-out means 5 to the hair implantation net 100 for implantation, wherein the pull-out means 5 can engage with the intermediate part of the hair material 101 in the hair material supply unit 6. The system has multiple types of pull-out hook sections 50a to 50c, each having a functional hook portion 56, and a switching mechanism 51 that allows switching between the pull-out hook sections 50a to 50c that pull out the hair material 101 from within the hair material supply section 6. Among the multiple types of pull-out hook sections 50a to 50c, there is a first pull-out hook section 50a and a second pull-out hook section 50b, which has a hook portion 56 that can engage with a larger number of hair materials 101 than the hook portion 56 of the first pull-out hook section 50a. Therefore, the number of hair materials 101 to be implanted on the hair implantation net 100 during the hair implantation operation can be adjusted by the type of pull-out hook section 50 used, and the amount (density) of hair materials 101 per unit area can be easily adjusted.

[0045] According to the hair implantation device 1 of the first embodiment, multiple types of pull-out hooks 50 can be attached to the switching mechanism 51, and the pull-out hook 50 used can be automatically and arbitrarily changed depending on the hair implantation pattern. Therefore, for example, in a single product such as a general-purpose wig, control such as reducing the number of hairs implanted at the hairline and increasing the number at the crown can be performed continuously without stopping the device, enabling the efficient production of higher quality products.

[0046] According to the hair implantation device 1 of the first embodiment, the pulling means 5 is capable of pulling out hair material 101 from the hair material supply unit 6 by a pulling hook portion 50 positioned at the pullable position P1 among a plurality of types of pulling hook portions 50a to 50c, and the switching mechanism 51 has a plurality of holding portions that hold the plurality of types of pulling hook portions 50a to 50c, and the positions of the plurality of holding portions can be moved, and it is preferable that the switching mechanism 51 moves the pulling hook portion 50 to be pulled out from inside the hair material supply unit 6 to the pullable position P1 by moving the holding portions. This makes it easier to set the pulling hook portion 50 to be used for the hair implantation operation.

[0047] In the hair implantation device 1 of the first embodiment, it has a rotating part 52 that can rotate around a rotation axis L1, and a plurality of holding parts are provided on the rotating part 52 and are arranged at intervals in the circumferential direction around the rotation axis L1, and it is preferable that the switching mechanism 51 rotates the rotating part 52 relative to the base part 53 to move the pull-out hook part 50 that is pulled out from inside the hair material supply part 6 to the pull-out position P1. This makes it easier to set the pull-out hook part 50 used for the hair implantation operation.

[0048] In the hair implantation device 1 of the first embodiment, it is preferable that the multiple holding parts are arranged such that the multiple pull-out hook parts 50a to 50c extend in the same direction. This makes it easier to align with the hair material supply part 6.

[0049] Next, a hair implantation device 201 according to a second embodiment of the present invention will be described. Components similar to those in the hair implantation device 1 of the first embodiment will be denoted by the same reference numerals and their description will be omitted. The same applies hereafter.

[0050] The hair implantation device 201 of the second embodiment of the present invention comprises an eccentric section 2, a hair implantation hook section 3, a pulling means 205, a hair material supply section 6, a guide roll 7, a hair material pull-in section 8, a hair material drop-in section 10, and a conveying roll 11. In other words, the hair implantation device 201 differs from the hair implantation device 1 of the first embodiment in that the pulling means 205 is different.

[0051] (Drawing means 205) As shown in Figure 4, the pull-out mechanism 205 is equipped with multiple types of pull-out hook sections 50 (50a to 50c) and a switching mechanism 251, which allows switching between the pull-out hook sections 50 used in the hair implantation operation. The switching mechanism 251 comprises a main body section 252a to 252c and a transport section 253.

[0052] As shown in Figure 4, the main body sections 252a to 252c are cylindrical bodies having a housing hole 257, and each housing hole 257 is equipped with a holding part (not shown) that holds the base end of each pull-out hook section 50.

[0053] The transport section 253 supports each main body section 252a to 252c and transports each main body section 252a to 252c in the transport direction so that the position of the pull-out hook section 50 to be used becomes the pull-out position P1. The transport unit 253 can move the main body units 252a to 252c horizontally by traveling horizontally. The conveying direction of the conveying unit 253 may be the longitudinal direction of the bottom 61 of the hair material supply unit 6 (the direction in which the hair material 101 extends), or it may be the width direction of the bottom 61 of the hair material supply unit 6 (a direction perpendicular to the direction in which the hair material 101 extends).

[0054] The pull-out mechanism 205, for example, when the first pull-out hook section 50a is positioned at the pull-out position P1 as shown in Figure 4(a), and it is to change to the second pull-out hook section 50b, transports the main body section 252b corresponding to the second pull-out hook section 50b to the pull-out position P1 by the transport section 253, as shown by the arrow in Figure 4(a), and exposes the second pull-out hook section 50b from the housing hole 257 of the main body section 252b, as shown in Figure 4(b), while retracting the first pull-out hook section 50a into the housing hole 257 of the main body section 252a. In this way, the pull-out hook section 50 that is located at the pull-out position P1 and can be used in the flocking operation can be switched from the first pull-out hook section 50a to the second pull-out hook section 50b.

[0055] In the hair implantation device 201 of the second embodiment, there is a transport unit 253 that transports a plurality of holding units, and the plurality of holding units are arranged at intervals in the transport direction of the transport unit 253, and it is preferable that the switching mechanism 251 moves the pull-out hook unit 50, which is pulled out from inside the hair material supply unit 6, to the pull-out position P1 as the transport unit 253 transports the holding units. This makes it easier to set the pull-out hook unit 50 to be used in the hair implantation operation.

[0056] Next, a hair implantation device 301 according to a third embodiment of the present invention will be described.

[0057] The hair implantation device 301 of the third embodiment of the present invention comprises an eccentric section 2, a hair implantation hook section 3, a pulling means 305, a hair material supply section 6, a guide roll 7, a hair material pull-in section 8, a hair material drop-in section 10, and a conveying roll 11. In other words, the hair implantation device 301 differs from the hair implantation device 1 of the first embodiment in that the pulling means 305 is different.

[0058] (Drawing means 305) As shown in Figure 5, the pull-out mechanism 305 is equipped with multiple types of pull-out hook sections 50 (50a to 50c) and a switching mechanism 351, which allows switching between the pull-out hook sections 50 used in the hair implantation operation.

[0059] The switching mechanism 351 includes a rotating part 352. The rotating part 352 is a cylindrical portion and has a holding part 353 on its outer circumferential surface 355 for holding the base end of each pull-out hook part 50. The rotating part 352 is rotatable in the circumferential direction about the rotation axis L2, and the rotation axis L2 is parallel to the bottom 61 of the hair material supply part 6. In other words, a portion of the outer circumferential surface 355 of the rotating part 352 faces the outlet hole 60 of the hair material supply part 6 with a gap between them.

[0060] For example, when the first pull-out hook section 50a is positioned in the pull-out position P1 as shown in Figure 5(a), the pull-out means 305 rotates the rotating part 352 circumferentially around the rotation axis L2, as indicated by the arrow in Figure 5(a), to position the second pull-out hook section 50b in the pull-out position P1 as shown in Figure 5(b). In this way, the pull-out hook section 50 that is positioned in the pull-out position P1 and usable in the hair implantation operation can be switched from the first pull-out hook section 50a to the second pull-out hook section 50b.

[0061] In the third embodiment of the hair implantation device 301, it is preferable that the plurality of holding parts 353 are arranged such that multiple types of pull-out hook parts 50a to 50c extend radially from the rotating part 352. This allows the pull-out hook parts 50 used in conjunction with the rotation of the rotating part 352 to be positioned at the pull-out position P1.

[0062] Next, a hair implantation device 401 according to a fourth embodiment of the present invention will be described.

[0063] The hair implantation device 401 of the fourth embodiment of the present invention comprises an eccentric section 2, a hair implantation hook section 3, a pulling means 405, a hair material supply section 6, a guide roll 7, a hair material pull-in section 8, a hair material drop-in section 10, and a conveying roll 11.

[0064] (Drawer means 405) As shown in Figure 6, the pull-out mechanism 405 is equipped with multiple pull-out hook sections 50a, 50b and a switching mechanism 451, which can be used to switch between the pull-out hook sections 50a, 50b used in the hair implantation operation. The switching mechanism 451 includes holding parts 452a and 452b that hold the bases of each pull-out hook section 50a and 50b, and a transport section (not shown) that can move each holding part 452a and 452b individually. The holding sections 452a and 452b are transported by a transport section such as an air cylinder so that the pull-out hook sections 50a and 50b are positioned at the pull-out position P1.

[0065] Next, the switching operation of the pull-out hook sections 50a and 50b of the hair implantation device 401 of the fourth embodiment will be described.

[0066] When hair implantation is not performed using the pull-out hook sections 50a and 50b of the hair implantation device 401, i.e., in the initial state, as shown in Figure 6(a), the holding sections 452a and 452b do not overlap in the vertical direction, are separated by a horizontal component (in this embodiment, the longitudinal component of the hair material 101), and are in a position where they do not interfere with each other. When hair implantation is to be performed using the pull-out hook section 50a from the initial state of the hair implantation device 401, the conveying section raises the holding section 452a vertically so that the pull-out hook section 50a is positioned at the pull-out position P1 directly below the outlet hole 60 of the hair material supply section 6, as shown in Figure 6(b), thereby achieving the first hair implantation preparation state in which the pull-out hook section 50a is positioned at the pull-out position P1. On the other hand, when hair implantation is performed using the pull-out hook section 50b from the initial state of the hair implantation device 401, the transport section (first transport section) raises the holding section 452b diagonally upward so that the pull-out hook section 50b is positioned at the pull-out position P1 directly below the outlet hole 60 of the hair material supply section 6, as shown in Figure 6(c), resulting in a second hair implantation preparation state where the pull-out hook section 50b is positioned at the pull-out position P1. In other words, the hair implantation device 401 has a pull-out position P1 above the pull-out hook portion 50a in the vertical direction, and in both cases, whether hair implantation is performed with the pull-out hook portion 50a or with the pull-out hook portion 50b, the switching mechanism 451 positions the pull-out hook portions 50a and 50b at the same pull-out position P1.

[0067] Furthermore, when switching from the first hair implantation preparation state to the second hair implantation preparation state, the hair implantation device 401 lowers the holding part 452a vertically by the transport unit from the pull-out position P1, and raises the holding part 452b diagonally upward by the transport unit to enter the second hair implantation preparation state. Similarly, when switching from the second hair implantation preparation state to the first hair implantation preparation state, the hair implantation device 401 lowers the holding part 452b diagonally downward from the pull-out position P1 by the transport unit, and raises the holding part 452a in the vertical direction to reach the first hair implantation preparation state.

[0068] Thus, according to the hair implantation device 401 of the fourth embodiment, when implanting hair using the pull-out hook sections 50a and 50b, the pull-out hook sections 50a and 50b can be switched without the holding sections 452a and 452b coming into contact with each other and interfering with one another.

[0069] In the fourth embodiment, the hair implantation device 401 has a pull-out means 405 that can pull out hair material 101 from the hair material supply unit 6 (hair material storage unit) using hook parts 50a and 50b from among a plurality of types of hook parts 50a and 50b that are positioned at the pull-out position P1. The switching mechanism 451 has a holding part 452b that holds the hook parts 50b and a transport part that transports the holding part 452b. The transport part transports the holding part 452b from a position that is vertically below the pull-out position P1 and horizontally offset from the pull-out position P1, and can transport the hook part 50b held by the holding part 452b to the pull-out position P1. Therefore, when other hook parts 50a move to the pull-out position P1, the holding part 452b and hook parts 50b are less likely to get in the way and interfere with each other.

[0070] In the embodiments described above, the pull-out means 5,205,305 were equipped with three types of pull-out hook portions 50a to 50c, but the present invention is not limited thereto. The pull-out means 5,205,305 may be equipped with two types of pull-out hook portions 50, or with four or more types of pull-out hook portions 50. Similarly, in the fourth embodiment, the pull-out means 405 was equipped with two types of pull-out hook portions 50a and 50b, but the present invention is not limited thereto. The pull-out means 405 may be equipped with three or more types of pull-out hook portions 50.

[0071] In the embodiment described above, the pulling means 5 automatically switched the pulling hook portion 50 used in the hair implantation operation by the switching mechanism 51. However, the present invention is not limited thereto, and the pulling hook portion 50 used in the hair implantation operation may be manually switched by the switching mechanism 51.

[0072] In the embodiment described above, each holding part of the switching mechanism 51 automatically moves the retractable hook parts 50a to 50c in the axial direction of the needle shaft part 55 by the retractable mechanism. However, the present invention is not limited thereto, and each holding part of the switching mechanism 51 may manually move the retractable hook parts 50a to 50c in the axial direction of the needle shaft part 55.

[0073] In the first and second embodiments described above, the pull-out means 5,205 retracted the pull-out hook portion 50 not used for the hair implantation operation into the housing hole 57,257, and exposed the pull-out hook portion 50 used for the hair implantation operation from the housing hole 57,257. However, the present invention is not limited thereto. It is not necessary to retract the pull-out hook portion 50 not used for the hair implantation operation into the housing hole 57,257.

[0074] In the second embodiment described above, the main body portions 252a to 252c were provided separately to correspond to the pull-out hook portions 50a to 50c, but the present invention is not limited thereto. A single main body portion 252 may be provided to correspond to multiple pull-out hook portions 50.

[0075] In the fourth embodiment described above, one holding part 452a rises vertically to position the pull-out hook part 50a at the pull-out position P1, and the other holding part 452b moves in a direction intersecting the vertical direction (first inclination direction) to position the pull-out hook part 50b at the pull-out position P1. However, the present invention is not limited thereto. The other holding part 452b may move the pull-out hook part 50b at the pull-out position P1 through multiple steps. That is, the other holding part 452b may move in a direction intersecting the vertical direction, and then rise vertically to move the pull-out hook part 50b at the pull-out position P1. Alternatively, one of the holding parts 452a may also be moved diagonally upward to position the pull-out hook part 50a in the pull-out position P1. That is, one of the holding parts 452a may be moved in a direction intersecting the vertical direction and in a direction different from the first inclination direction of the other holding part 452b to position the pull-out hook part 50a in the pull-out position P1. Of course, in this case as well, the pull-out hook part 50a may be moved to the pull-out position P1 through multiple steps.

[0076] In the embodiments described above, the components can be freely substituted or added between each embodiment, as long as they fall within the technical scope of the present invention. [Explanation of Symbols]
