[0004] Incidentally, there are cases where nail treatment tools such as those described in Patent Document 1 are stored in a case for storage or transport. However, there are cases where the stored nail treatment tool moves within the case or is difficult to grasp when removing it from the case, making it difficult to remove the nail treatment tool from the case.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a storage case for nail treatment tools that allows easy removal of the nail treatment tools. [Means for solving the problem]

[0006] The storage case for a nail treatment tool of the present invention is a storage case for a nail treatment tool for storing a nail treatment tool that is driven by a drive unit to treat nails, wherein the nail treatment tool comprises a rod-shaped shaft portion that is attached to and detached from the drive unit, a flange portion that extends radially outward from the shaft portion, and a processing portion that is provided on the flange portion for treating nails, and the storage case comprises a storage section for storing the nail treatment tool, wherein the storage section has a storage recess that is concave on the back side and into which the shaft portion can be inserted from the front side, and the storage recess can hold the shaft portion inserted into the storage recess with the flange portion spaced apart from the front edge of the storage recess.

[0007] With this configuration, the shaft is supported in the storage recess, and a gap is formed between the flange and the front edge of the storage recess, so that the nail treatment tool can be prevented from moving in the storage case for nail treatment tools, and moreover, it is easy to insert a finger into the gap and hook it on the flange, making it easy to grasp the nail treatment tool with your fingers.

[0008] The storage section may be configured to be able to store a plurality of nail treatment tools side by side.

[0009] According to this configuration, a plurality of nail treatment tools can be stored side by side, so that the nail treatment tools can be stored neatly.

[0010] The nail processing tool may also include a large diameter processing tool and a small diameter processing tool whose flange has an outer diameter smaller than that of the large diameter processing tool, and the storage section may be configured to be able to store the large diameter processing tool and the small diameter processing tool side by side.

[0011] According to this configuration, multiple nail treatment tools with different outer diameters of the flange portion can be stored side by side with the flange portion spaced away from the front edge of the storage recess, so that multiple nail treatment tools of different sizes can be stored in a state where they can be easily taken out.

[0012] In addition, the nail processing tool may include a large diameter processing tool and a small diameter processing tool having a flange portion with a smaller outer diameter than that of the large diameter processing tool, and the storage section may be configured to have a dual-purpose storage recess that is capable of holding the shaft portion of the large diameter processing tool and the shaft portion of the small diameter processing tool.

[0013] According to this configuration, both large diameter processing tools and small diameter processing tools can be stored in the multipurpose storage recess, so that multiple types of nail processing tools can be stored in one storage recess, making it convenient to use.

[0014] The nail processing tool includes a flat processing tool having a flat processing portion and a rod-shaped processing tool having a rod-shaped processing portion, and the storage portion can be configured to be capable of holding the shaft portion inserted into the storage recess with the flange portion of the flat processing tool spaced away from the front edge of the storage recess toward the front side, and to be capable of holding the shaft portion inserted into the storage recess with the flange portion of the rod-shaped processing tool abutting the front edge of the storage recess.

[0015] According to this configuration, the flat processing tool is stored with its flange part spaced away from the front edge of the storage recess, making it easy to grab and remove, and the rod-shaped processing tool is easy to grab and remove as it is a rod-shaped processing part, and moreover, the flange part abuts against the front edge of the storage recess, making it fit well within the case.

[0016] The storage portion may also be configured to include contact holding portions that hold the shaft portion by making point contact with the shaft portion inserted into the storage recess at a plurality of locations.

[0017] With this configuration, the storage section makes point contact with the shaft section at multiple points, thereby stably supporting the shaft section, and furthermore, the resistance that the shaft section experiences when removing the nail treatment tool can be reduced, making it easier to remove the nail treatment tool. [Effects of the Invention]

[0020] A storage case 1 for nail treatment tools according to one embodiment of the present invention will be described with reference to Figs. 1 to 12. For convenience of explanation, the front-to-back direction, front-to-rear direction, and left-to-right direction will be described based on the directions shown in Fig. 1.

[0021] 1, the nail treatment tool storage case 1 includes a box-shaped case body 2 that forms a storage space capable of storing a nail treatment tool 7 and a drive device 8 therein, and a storage section 3 provided in the case body 2. The nail treatment tool storage case 1 of this embodiment is generally a rectangular box with rounded corners, and is longer in the left-right direction than in the front-to-back direction, and is also longer in both the front-to-back and left-to-right directions than in the front-to-rear direction.

[0022] The case body 2 includes a base 21, a lid 22, and an opening / closing mechanism 23 that connects the lid 22 to the base 21 so that the lid 22 can be opened and closed. The base 21 includes a flat, plate-shaped back surface 211 and a plate-shaped base-side lateral surface 212 that extends from the outer edge of the back surface 211 to the front side. The lid 22 includes a plate-shaped front surface 221 and a plate-shaped lid-side lateral surface 222 that extends from the outer edge of the front surface 221 to the back side. When the lid 22 is closed, the base 21 and the lid 22 are configured to form a closed box shape with the front surface 221 and the back surface 211 facing each other in the front-to-back direction and the base-side lateral surface 212 and the lid-side lateral surface 222 extending continuously in the front-to-back direction, and a storage space is formed inside the base 21 and the lid 22. In addition, in this embodiment, when the lid 22 is closed, the base-side side surface portion 212 and the lid-side side surface portion 222 are continuous without any steps, resulting in a smooth side surface of the case body 2. Furthermore, the base-side side surface portion 212 and the lid-side side surface portion 222 are provided with legs 24 that protrude laterally. The legs 24 in this embodiment are protruding portions that protrude to the right from the base-side side surface portion 212 and the lid-side side surface portion 222, and are configured to extend continuously from the base-side side surface portion 212 to the lid-side side surface portion 222 when the lid 22 is closed (see FIG. 12 ).

[0023] The opening / closing mechanism 23 includes an opening / closing connecting part 231 that connects the base 21 and the lid part 22, a biasing part 232, and an opening / closing operating part 233 for operating to open the lid part 22. The opening / closing connecting part 231 is a hinge that connects the rear ends of the base 21 and the lid part 22 so that the lid part 22 can be opened and closed by rotating about an axis that extends in the left-right direction relative to the base 21. The biasing part 232 is an elastic body that biases the lid part 22 in the opening direction. In this embodiment, the biasing part 232 is a plate-like body made of soft resin that abuts against the inner surface of the lid part 22 and biases the lid part 22 to rotate in the opening direction.

[0024] Opening / closing operation unit 233 is configured to be switchable between a state in which lid unit 22 maintains a closed state against the bias of biasing unit 232, and a state in which lid unit 22 can be opened by the bias of biasing unit 232. Specifically, opening / closing operation unit 233 includes locking protrusion 234, which is a protrusion provided on lid unit 22, and opening / closing lever 235, which is provided on base 21 and can be engaged with and disengaged from locking protrusion 234. Locking protrusion 234 is a protrusion that protrudes forward from the front end of lid unit 22.

[0025] The opening / closing lever 235 includes a locking plate 236 having a recess formed therein that can be locked onto the locking protrusion 234, and a finger hook 237. The locking plate 236 is a plate-like body extending in the front-to-back direction, and the recess is configured to be movable toward and away from the locking protrusion 234. The locking plate 236 of this embodiment is provided at the front end of the storage section 3, and since the storage section 3 is provided on the base 21, the locking plate 236 is provided on the base 21 via the storage section 3. The locking plate 236 is also rotatable about an axis extending in the left-right direction around its lower end, and the rotation causes the recess to move toward and away from the locking protrusion 234. Furthermore, the locking plate 236 of this embodiment is a leaf spring that can be locked onto the locking protrusion 234 in its natural state and is configured to elastically deform and move away from the locking protrusion 234. Finger hook 237 is a plate-like body that is provided at the upper end of locking plate 236 and extends in a direction intersecting locking plate 236. Finger hook 237 in this embodiment is a plate-like body that is inclined with respect to the front-to-back direction so that the rear side, which is the side closer to locking protrusion 234, is located on the back side, and the front side, which is the side farther from locking protrusion 234, is located on the front side. Because finger hook 237 is inclined in this manner, it is easy to hook a finger on finger hook 237 and move locking plate 236 in a direction away from locking protrusion 234.

[0026] 1 and 2, the storage unit 3 is a plate-like body large enough to be stored inside the storage space. In this embodiment, the storage unit 3 is stored inside the storage space while fitted to the base 21. The storage unit 3 includes a processing tool storage unit 4 that stores the nail processing tool 7, and a device storage unit 5 that stores a drive unit 8 for driving the nail processing tool 7. In this embodiment, the processing tool storage unit 4 and the device storage unit 5 are arranged side by side in the front-to-rear direction, and specifically, the processing tool storage unit 4 is located behind the device storage unit 5.

[0027] 2 and 3, the processing tool storage section 4 has a storage recess 6 that is concave on the back side and into which the shaft 71 of the nail processing tool 7 can be inserted, and a flange abutment section 41 that is convex on the front side and can abut against the back surface of the flange 72 of the nail processing tool 7. The processing tool storage section 4 has a plurality of storage recesses 6 that are arranged side by side in the left-right direction, and the flange abutment section 41 that extends along the direction in which the plurality of storage recesses 6 are arranged.

[0028] The processing tool storage section 4 has a hole 4a extending elongated in a direction perpendicular to the front-to-back direction and having a recessed hole formed on the back side. In this embodiment, the hole 4a is an elongated hole extending in the left-to-right direction. Specifically, the hole 4a includes a pair of curved wall portions 42 located at both left-to-right ends, extending in the up-down direction and curved so as to be convex outward in the left-to-right direction, and a pair of straight wall portions 43 extending in the left-to-right and up-to-down directions and connecting the pair of curved wall portions 42. The hole 4a has arc-shaped ends in the left-to-right direction and a straight portion extending in the left-to-right direction. The hole 4a is partitioned midway in the longitudinal direction, thereby forming multiple storage recesses 6. Therefore, the storage recesses 6 are arranged in a row in the longitudinal direction of the hole 4a. Furthermore, the flange abutment portion 41 extends from one end of the hole 4a to the other end in the left-to-right direction.

[0029] The storage recess 6 includes a storage bottom portion 61 that forms the bottom of the storage recess 6, storage side portions 62 that extend from the front and rear outer edges of the storage bottom portion 61 to the front side, a storage surface portion 63 that extends from the front end of the storage side portion 62 toward the outside of the storage recess 6 in a direction intersecting the front-to-back direction, and a contact holding portion 64. The storage side portion 62 in this embodiment is formed by at least one of a curved wall portion 42 and a straight wall portion 43. Furthermore, each storage recess 6 in this embodiment is a multi-purpose storage recess that can accommodate various types of nail treatment tools 7 (large-diameter treatment tools 7A, small-diameter treatment tools 7B, and rod-shaped treatment tools 7C).

[0030] The storage bottom 61 is plate-shaped and extends in the front-rear and left-right directions. The storage bottom 61 is plate-shaped and extends from the storage side surface 62 toward the inside of the storage recess 6. The storage bottom 61 is also formed with a front-rear slit 61a extending in the front-rear direction and a left-right slit 61b extending in the left-right direction. The front-rear slit 61a extends from the front end to the rear end of the storage bottom 61 and, in this embodiment, is formed in the left-right center of the storage recess 6. The left-right slit 61b extends continuously in the left-right direction and is formed in the front-rear center of the storage recess 6. Here, the storage bottom 61 includes a divided bottom 611 divided midway in the front-rear direction by the front-rear slit 61a and a continuous bottom 612 extending from the front storage side surface 62 to the rear storage side surface 62. Multiple divided bottoms 611 are located between the continuous bottoms 612 in the left-right direction. Furthermore, the storage bottom 61 extends continuously to the adjacent storage recess 6.

[0031] The storage side surface 62 is a wall extending from the front and rear ends of the storage bottom 61 to the front side. The storage side surface 62 is also formed with front-rear slits 62a extending in the front-rear direction (see FIGS. 9 and 10). The front-rear slits 62a extend from the rear end of the storage side surface 62 to the middle of the front side. The front-rear slits 62a are not formed at the front end of the storage side surface 62, but extend continuously without interruption along the front end of the storage side surface 62. In this embodiment, the front-rear slits 62a are formed in the center of the storage recess 6 in the left-right direction and extend continuously with the front-rear slits 61a of the storage bottom 61. The storage side surface 62 of the end storage recess 6A located at both left-right ends is formed by the curved wall 42 and the straight wall 43, while the storage side surface 62 of the middle storage recess 6B located midway in the left-right direction is formed by the straight wall 43.

[0032] The storage surface portion 63 is a plate-like member that extends from the storage side portion 62 to the outside of the storage recess 6, and is located entirely behind or at approximately the same position as the front end of the processing tool storage portion 4 in the front-to-back direction. The storage surface portion 63 also forms the front edge of the storage recess 6.

[0033] The contact holder 64 abuts against the shaft 71 of the inserted nail treatment tool 7 to hold the nail treatment tool 7. The contact holder 64 is configured to abut against the shaft 71 of the inserted nail treatment tool 7 and elastically deform, holding the shaft 71 of the nail treatment tool 7 by its restoring force. Specifically, the contact holder 64 is configured to extend from the storage side surface 62 toward the inside of the storage recess 6. The contact holder 64 also has a contact plane 64a that can abut against the shaft 71. The contact holder 64 of this embodiment includes a plate-shaped contact piece 642 that extends from the straight wall portion 43 toward the inside of the storage recess 6 and a contact protrusion 641 that protrudes from the curved wall portion 42 toward the inside of the storage recess 6, with both left and right end surfaces of the contact piece 642 being the abutment plane 64a, and the end surface of the abutment protrusion 641 inside the storage recess 6 being the abutment plane 64a. The contact pieces 642 extend from the front and rear straight wall portions 43 toward the inside of the storage recess 6 and are arranged to face each other in the front-rear direction. In addition, front-rear slits 61a are located on both sides of the contact pieces 642 in the left-right direction.

[0034] A plurality of storage recesses 6 are formed by dividing elongated holes extending in the left-right direction in the hole 4a with abutment pieces 642. Therefore, the storage recesses 6 are aligned in a straight line along the longitudinal direction of the elongated holes formed in the hole 4a. Furthermore, the abutment pieces 642 serve as the abutment pieces 642 for both adjacent storage recesses 6. Two contact retainers 64 are provided on the right side and two on the left side of each storage recess 6. Specifically, the end storage recess 6A is provided with abutment protrusions 641 at two locations on the end side of the hole 4a in the left-right direction, and abutment pieces 642 are provided on the opposite side of the end of the hole 4a, spaced apart from each other in the front-rear direction. Furthermore, the intermediate storage recess 6B is provided with abutment pieces 642 on the left and right sides, spaced apart from each other in the front-rear direction. Furthermore, the distance between the abutment planes 64a spaced apart in the left-right direction is configured to be slightly smaller than the width of the corresponding portion of the shaft portion 71 that it holds.

[0035] The flange contact portion 41 is a portion that protrudes outward from the storage surface portion 63. The flange contact portion 41 is disposed at a position spaced apart from the end portion on the front side of the storage side portion 62. In this embodiment, the flange contact portion 41 is disposed at approximately equal distances from each storage recess 6.

[0036] The device storage section 5 includes a main body storage section 51 that stores the drive device 8, and an attachment storage section 52 that stores the nail treatment tool 7 attached to the drive device 8. The main body storage section 51 is recessed on the back side in a shape corresponding to the drive device 8, and is configured so that the drive device 8 can be fitted into it.

[0037] The attachment storage section 52 is a recess that can store the nail treatment tool 7 attached to the drive unit 8. Furthermore, the attachment storage section 52 of this embodiment can store the nail treatment tool 7 attached to the drive unit 8, and specifically, can store the small diameter treatment tool 7B and the large diameter treatment tool 7A, which are flat treatment tools. The attachment storage section 52 is a recess that extends continuously from the main body storage section 51, and is recessed in a shape that corresponds to the nail treatment tool 7 attached to the drive unit 8.

[0038] Next, the nail treatment tool 7 and the drive unit 8 stored in the nail treatment tool storage case 1 will be described with reference to FIGS. 4 to 8. In this embodiment, a plurality of nail treatment tools 7 are provided depending on the size of the nails to be treated and the type of treatment. Specifically, the nail treatment tools 7 include a large-diameter treatment tool 7A shown in FIGS. 4 and 5 and a small-diameter treatment tool 7B shown in FIG. 6, which are flat treatment tools, and a rod-shaped treatment tool 7C shown in FIG. 7.

[0039] 4 and 5, the large diameter processing tool 7A includes a rod-shaped shaft portion 71, a large diameter flange portion 72A that is a flange portion 72 extending radially outward from the shaft portion 71, and a flat plate-shaped flat processing portion 731. In this embodiment, multiple types of large diameter processing tools 7A are provided, each with a different configuration of the flat plate processing portion 731. The shaft portion 71 and large diameter flange portion 72A of each large diameter processing tool 7A have the same configuration.

[0040] The shaft 71 is a rod-like cylindrical member with a substantially uniform outer shape, and can be attached to the drive unit 8. One axial end of the shaft 71 forms a processing bottom 74, which is the bottom of the nail processing tool 7, and the other axial end is connected to the large diameter flange 72A. The shaft 71 is also formed with an attachment hole 71a extending from the processing bottom 74 toward the other end in the axial direction, and the drive shaft 83 of the drive unit 8 can be inserted through the attachment hole 71a. The length of the shaft 71 of the large diameter processing tool 7A is shorter than the distance from the front end of the flange abutment portion 41 to the storage bottom 61 of the storage recess 6, and is also shorter than the distance from the storage bottom 61 to the storage surface portion 63 of the storage recess 6.

[0041] The large-diameter flange 72A is plate-shaped and extends radially outward from the other axial end of the shaft 71. In this embodiment, the large-diameter flange 72A is a circular plate-shaped body provided coaxially with the shaft 71. The large-diameter flange 72A has flat surfaces on both the axial end and the axial end that extend in a direction perpendicular to the axial direction. The large-diameter flange 72A is large enough that its back surface can abut against the flange abutment portion 41 when the shaft 71 is inserted into the storage recess 6. The specific configuration of the large-diameter flange 72A can be various configurations suitable for providing the flat plate processing portion 731. For example, a configuration in which multiple large-diameter processing tools 7A each have a large-diameter flange 72A with a different shape can be used.

[0042] The flat plate processing section 731 is a flat plate-shaped body provided on the surface of the other axial end of the large-diameter flange 72A, and is configured to be able to process nails by contacting the nail when driven by the drive device 8. Specifically, the flat plate processing section 731 is a file configured to be able to grind nails by contacting the nail when driven, and has an uneven surface for grinding nails. The flat plate processing section 731 is arranged so as to spread over the entire surface of the other axial end of the flange 72. In this embodiment, multiple types of flat plate processing sections 731 are provided, each with a different hardness and uneven surface configuration for grinding nails, and each type of flat plate processing section 731 is provided on the flange 72 of the corresponding large-diameter processing tool 7A.

[0043] 6, the small diameter processing tool 7B includes a rod-shaped shaft 71, a small diameter flange 72B that is a flange 72 extending radially outward from the shaft 71, and a flat plate processing part 731. In this embodiment, multiple types of small diameter processing tools 7B are provided, each with a different configuration of the flat plate processing part 731. The shaft 71 and small diameter flange 72B of each small diameter processing tool 7B have the same configuration. Furthermore, the axial length of the shaft 71 of the small diameter processing tool 7B is longer than the distance from the storage bottom 61 to the storage surface part 63 in the storage recess 6.

[0044] The small-diameter flange 72B is plate-shaped and extends radially outward from the other axial end of the shaft 71. The small-diameter processing tool 7B has an outer diameter smaller than that of the large-diameter flange 72A. In this embodiment, the small-diameter flange 72B is a circular plate-shaped body coaxial with the shaft 71. The surfaces of the small-diameter flange 72B at one end and the other end in the axial direction are flat surfaces that extend in a direction perpendicular to the axial direction. The small-diameter flange 72B is sized so that its back surface does not abut against the flange abutment portion 41 when the shaft 71 is inserted into the storage recess 6. The small-diameter flange 72B may have various configurations suitable for providing the flat-plate processing portion 731. For example, multiple small-diameter processing tools 7B may each have a small-diameter flange 72B with a different shape.

[0045] The flat plate processing section 731 is a plate-like body provided on the surface of the other axial end of the small diameter flange 72B, and is configured to be able to process the nails by coming into contact with the nails while driven by the drive unit 8. The flat plate processing section 731 is arranged so as to extend over the entire surface of the other axial end of the small diameter flange 72B. The flat plate processing section 731 of the small diameter processing tool 7B of this embodiment has the same configuration as the flat plate processing section 731 of the large diameter processing tool 7A, except that it is sized to correspond to the small diameter flange 72B, although flat plate processing sections 731 with different configurations may also be used.

[0046] 7, rod-shaped processing tool 7C includes a rod-shaped shaft 71, rod-shaped flange 72C, which is flange 72 extending radially outward from shaft 71, and rod-shaped processing section 732. Shank 71 of rod-shaped processing tool 7C has the same configuration as shaft 71 of large-diameter flange 72A and small-diameter flange 72B, except that its axial length is shorter than those of shaft 71 of large-diameter flange 72A and small-diameter flange 72B. Specifically, the axial length of shaft 71 of rod-shaped processing tool 7C is approximately the same as or shorter than the distance from storage bottom 61 to storage surface 63 in storage recess 6.

[0047] The rod flange portion 72C is in the shape of a plate that spreads radially outward from the other axial end portion of the shaft portion 71. The rod flange portion 72C has an outer shape smaller than the outer diameters of the large diameter flange portion 72A and the small diameter flange portion 72B.

[0048] The rod-shaped processing part 732 is a rod-shaped body extending from the rod flange part 72C toward the other end in the axial direction, and is configured to be able to process a nail by coming into contact with the nail when driven by the drive device 8. The rod-shaped processing part 732 is a file configured to be able to grind a nail by bringing its outer circumferential surface into contact with the nail when driven, and has irregularities formed on its outer circumferential surface for grinding the nail.

[0049] The drive unit 8 includes a drive main body 81 that generates a drive force, and a drive mounting part 82 that is provided at the tip of the drive main body 81 and to which the nail treatment tool 7 can be attached. The drive main body 81 is rod-shaped and small enough to be held in the hand, and is configured to accommodate a battery or the like as a drive source inside. Specifically, the drive main body 81 is configured to drive a motor using the drive source provided inside, thereby rotating a drive shaft 83 of the drive mounting part 82. The drive main body 81 also has a switch for turning the power of the drive unit 8 on and off.

[0050] The drive mounting part 82 is a socket into which the shaft 71 of the nail treatment tool 7 can be inserted. Specifically, the drive mounting part 82 has an insertion space formed therein that is recessed from the tip end to the rear end of the drive main body part 81, into which the shaft 71 can be inserted, and is provided with a drive shaft 83 that is located inside the insertion space and rotates by the driving force of the drive main body part 81. The drive shaft 83 is a rod-shaped body that can be inserted into the mounting hole 71a, and is configured to be able to rotate integrally with the shaft 71 when inserted into the mounting hole 71a.

[0051] The nail processing tool 7 attached to the drive device 8 has the other axial end protruding from the drive device 8 toward the tip side. Specifically, the other axial end of the shaft portion 71, the flange portion 72, and the processing portion 73 protrude from the drive device 8.

[0052] With such a nail treatment tool 7, nails can be treated by bringing the treatment part 73 into contact with the nail while the tool is attached to the drive unit 8 and driven. Specifically, an appropriate nail treatment tool 7 is selected based on the size of the nail to be treated and the treatment to be performed, and the appropriate nail treatment tool 7 is attached to the drive mounting part 82 and driven. The nail is then treated by bringing the treatment part 73 into contact with the nail. Furthermore, the nail treatment tool 7 attached to the drive mounting part 82 is changed depending on the treatment stage and the nail to be treated. Specifically, the nail treatment tool 7 attached to the drive mounting part 82 is changed by removing the nail treatment tool 7 attached to the drive mounting part 82 and attaching another nail treatment tool 7 to the drive mounting part 82.

[0053] Next, the storage state of the nail treatment tool 7 and the drive unit 8 will be described with reference to Figures 8 to 11. The nail treatment tool 7 and the drive unit 8 are stored in the nail treatment tool storage case 1. Specifically, the nail treatment tool 7 is stored in the treatment tool storage section 4, and the drive unit 8 is stored in the device storage section 5.

[0054] 8, a plurality of nail treatment tools 7 are stored in the treatment tool storage section 4 while being lined up in the arranging direction of the storage recesses 6. In this embodiment, the plurality of nail treatment tools 7 are stored while being lined up in a row along the arranging direction of the storage recesses 6 which are arranged in a straight line.

[0055] As shown in FIG. 9 , the nail treatment tool 7 is stored in the storage recess 6 by inserting and holding the shaft 71 in the storage recess 6. Specifically, the shaft 71 is inserted into the storage recess 6 until the treatment bottom 74 abuts against the storage bottom 61 or until the flange 72 abuts against the flange abutment 41. Here, the axial length of the shaft 71 of the small-diameter treatment tool 7B is longer than the distance from the storage bottom 61 to the storage surface 63, so that the other axial end of the shaft 71 protrudes from the storage surface 63 to the front side, and the flange 72 provided at the other axial end of the shaft 71 is positioned away from the front side of the storage surface 63. Therefore, the small-diameter flange 72B is spaced away from the storage surface 63 to the front side, with its back surface not abutting against the flange abutment 41. 8, the shaft 71 of the large-diameter processing tool 7A is inserted into the storage recess 6 until the back surface of the large-diameter flange 72A abuts against the flange abutment 41, and the abutment of the large-diameter flange 72A with the flange abutment 41 causes the large-diameter flange 72A to be spaced apart from the storage surface 63 to the front side. 9, the axial length of the rod-shaped processing tool 7C is approximately equal to the distance from the storage bottom 61 to the storage surface 63 or is shorter than the distance from the storage bottom 61 to the storage surface 63. Therefore, the other axial end of the shaft 71 is located at approximately the same position as the storage surface 63 or on the front side of the storage surface 63, and the flange 72 provided at the other axial end of the shaft 71 abuts against the storage surface 63. In this way, the rod-shaped processing tool 7C is stored with the flange 72 abutting against the storage surface 63, which reduces the amount of protrusion of the rod-shaped processing part 732 and allows for smooth storage. In this way, the large-diameter processing tool 7A and the small-diameter processing tool 7B, which are flat processing tools, can be placed in a state in which the flange 72 is spaced away from the storage surface 63 toward the front side by having the shaft 71, which is longer than the depth of the storage recess 6, abut against the storage bottom 61, or by having the flange 72 abut against the flange abutment 41 that protrudes from the storage surface 63 toward the front side.

[0056] As shown in FIG. 10 , the shaft portion 71 inserted into the storage recess 6 is held by the contact holding portion 64. In this embodiment, the distance between the abutment planes 64a of the contact holding portions 64 spaced apart on the left and right is smaller than the width of the corresponding portion of the shaft portion 71. Therefore, when the shaft portion 71 is inserted, the shaft portion 71 abuts against the contact holding portion 64 and pushes it outward toward the outside of the storage recess 6, causing the contact holding portion 64 to elastically deform. In this embodiment, the shaft portion 71, whose outer circumferential surface is arc-shaped, abuts against the flat abutment plane 64a, so that the shaft portion 71 is held in point contact with the contact holding portion 64. The shaft portion 71 is then held by the restoring force of the contact holding portion 64. In this embodiment, the abutment piece portion 642 of the contact holding portion 64 elastically deforms to hold the shaft portion 71. Here, the storage recess 6 is formed with front-rear slits 61a, left-right slits 61b, and front-rear slits 62a. Therefore, the abutment piece 642 elastically deforms, and the slits open, allowing the storage bottom 61 and the storage side surface 62 to elastically deform. Therefore, when the shaft 71 is inserted into the storage recess 6, the entire storage recess 6 can expand to accommodate the shaft 71, making it easier to insert the shaft 71 into the storage recess 6. Furthermore, because the linear wall portions 43 of the elongated holes forming the storage recess 6 are connected by the continuous bottom portion 612, even if a slit is formed in the storage bottom 61, a weakening of the force holding the shaft 71 can be prevented. Note that, in this embodiment, "holding" refers to a level of holding that prevents the nail treatment tool 7 from falling under its own weight, even when the shaft 71 is inserted into the storage recess 6 and the front side is facing vertically downward.

[0057] 8 and 9, when the shaft portion 71 is inserted into a storage recess 6, the flange portion 72 covers at least a portion of the upper side of the adjacent storage recess 6. Therefore, the configuration is such that another shaft portion 71 cannot be inserted into a storage recess 6 adjacent to the storage recess 6 in which the shaft portion 71 is stored. Therefore, since the configuration is such that the shaft portion 71 can only be inserted into one of the adjacent storage recesses 6 that share the abutting piece portion 642, even if the abutting piece portion 642 is shared between the adjacent storage recesses 6, the abutting piece portion 642 can be pushed apart by the shaft portion 71 and elastically deformed.

[0058] A description will be given of how to remove the thus stored nail processing tools 7. First, a method for removing the large diameter processing tool 7A and the small diameter processing tool 7B as flat processing tools will be described.

[0059] To remove the flat plate processing tool, the flange 72 is grasped with fingers and the entire nail processing tool 7 is pulled toward the front side against the grip of the contact holding portion 64. Here, because the flange 72 is positioned away from the storage surface portion 63, which is the front edge of the storage recess 6, a gap is formed between the storage surface portion 63 and the flange 72. Therefore, it is easy to insert a finger through the gap and hook the finger on the flange 72. This makes it easy to grasp the flange 72 and remove the nail processing tool 7 from the storage recess 6. In addition, because the back surface of the large-diameter flange 72A abuts against the flange abutment portion 41, the flat plate processing tool can be grasped using the flange abutment portion 41 as support. This makes it easy to grasp the large-diameter flange 72A and remove the nail processing tool 7 from the storage recess 6.

[0060] To remove the rod-shaped processing tool 7C, grasp the rod-shaped processing part 732 with your fingers and pull the entire nail processing tool 7 toward the front side against the holding force of the contact holding part 64. Here, the rod-shaped processing tool 7C is a rod-shaped body that extends in the opposite axial direction from the flange part 72, so it is easy to grasp with your fingers. Therefore, it is easy to remove even if the flange part 72 abuts against the storage surface part 63.

[0061] Next, the storage of the drive unit 8 will be described. As shown in FIGS. 8 and 11 , the drive unit 8 is stored in the device storage section 5 with the nail treatment tool 7 attached. Specifically, the drive unit 8 is stored in a state where it is fitted into the main body storage section 51, and the attached nail treatment tool 7 is stored in the attachment storage section 52. In this embodiment, the attachment storage section 52 can store the large-diameter treatment tool 7A and the small-diameter treatment tool 7B attached to the drive unit 8, but cannot store the rod-shaped treatment tool 7C. Furthermore, the attachment storage section 52 can store the nail treatment tool 7 attached to the drive unit 8 in a floating state. Specifically, the attachment storage section 52 forms a space large enough that the nail treatment tool 7 attached to the drive unit 8 does not abut against the wall surface that constitutes the attachment storage section 52. With this configuration, the drive unit 8 can be stored with the nail treatment tool 7 attached, thereby eliminating the need to attach and detach the nail treatment tool 7. Furthermore, when the nail treatment tool 7 in the stored state abuts against the attachment storage section 52, force is applied to the shaft 71 or the portion of the drive unit 8 to which the nail treatment tool 7 is attached (drive shaft 83 in this embodiment), which prevents damage to the nail treatment tool 7 or the drive unit 8. Note that the attachment storage section 52 can also be configured to accommodate a rod-shaped treatment tool 7C attached to the drive unit 8. Even with this configuration, it is possible to save the trouble of attaching and detaching the nail treatment tool 7, and also to prevent damage to the nail treatment tool 7 or the drive unit 8 when the nail treatment tool 7 in the stored state abuts against the attachment storage section 52.

[0062] 1 and 12, the nail treatment tool storage case 1 will be described with reference to the state in which the nail treatment tool 7 and the drive unit 8 are stored. When the lid portion 22 is closed with the nail treatment tool 7 and the drive unit 8 stored in the storage section 3, the nail treatment tool storage case 1 stores the nail treatment tool 7 and the drive unit 8 inside. Specifically, the lid portion 22 is closed against the bias of the biasing portion 232, and the locking protrusion of the opening / closing operation portion 233 is locked with the opening / closing lever portion 235, thereby closing the lid portion 22.

[0063] Here, the nail treatment tool storage case 1 with the lid 22 closed can store the nail treatment tools 7 and the drive device 8 in two positions: a lying position in which the back surface is in contact with a placement surface such as a shelf or desk, and an upright position in which the side surface is in contact with the placement surface. Specifically, in the lying position, the back surface of the base 21 is in contact with the placement surface. In the lying position, the flat back surface 211 is in contact with the placement surface, so the nail treatment tool storage case 1 is stable. In the upright position, the legs 24 provided on the base side 212 and the lid side 222 are in contact with the placement surface. Therefore, even if the base side 212 and the lid side 222 have an uneven surface such as an arc shape, the upright position can be maintained by the legs 24.

[0064] According to the nail treatment tool storage case 1 configured as described above, the shaft 71 is supported by the storage recess 6, and a gap is formed between the flange 72 and the front edge of the storage recess 6, so that the nail treatment tool 7 can be prevented from moving in the nail treatment tool storage case 1, and moreover, it is easy to insert a finger into the gap and hook the finger on the flange 72, so that the nail treatment tool 7 can be easily grasped with the fingers. Therefore, the nail treatment tool 7 can be easily taken out.

[0065] Furthermore, since a plurality of nail treatment tools 7 are stored side by side, the nail treatment tools 7 can be stored neatly.

[0066] Furthermore, since a plurality of nail treatment tools 7 are lined up in a row, the user can compare the lined up nail treatment tools 7 and select the nail treatment tool 7 to be used, and even if the nail treatment tools 7 are adjacent to each other, the user can easily grasp the nail treatment tools 7, making it easier to use the nail treatment tools 7.

[0067] Furthermore, since a plurality of nail treatment tools 7 having different outer diameters of the flange parts 72 can be stored side by side with the flange parts 72 spaced apart from the front edge of the storage recess 6 toward the front side, a plurality of nail treatment tools 7 of different sizes can be stored in a state where they can be easily taken out.

[0068] Furthermore, since both the large diameter processing tool 7A and the small diameter processing tool 7B can be stored in the dual-purpose storage recess, a plurality of types of nail processing tools 7 can be stored in one storage recess 6, making it convenient to use.

[0069] Furthermore, the flat processing tool is stored with the flange 72 spaced from the front edge of the storage recess 6, making it easy to grab and take it out, and the rod-shaped processing tool 7C is easy to grab and take out by gripping the rod-shaped processing part 73, and moreover, the flange 72 abuts against the front edge of the storage recess 6, making it easy to fit inside the case.

[0070] Furthermore, since the storage section 3 comes into point contact with the shaft section 71 at multiple points, the shaft section 71 can be stably supported, and the resistance received by the shaft section 71 when the nail treatment tool 7 is taken out can be suppressed, making it easier to take out the nail treatment tool 7.

[0071] The above describes an embodiment of the present invention using an example, but the present invention is not limited to the above embodiment, and various modifications can be made within the scope that does not deviate from the gist of the present invention.

[0072] For example, although the storage section 3 has been described as having a plurality of storage recesses 6, the present invention is not limited to this configuration, and the storage section 3 may have only one storage recess 6.

[0073] In addition, although the above description has been given with reference to an example in which the storage recesses 6 are linearly arranged in the left-right direction and multiple nail processing tools 7 are held in the storage recesses 6 in a row, the present invention is not limited to this configuration. For example, as shown in FIG. 13, the storage recesses 6 may be arranged in a diagonal direction intersecting the left-right direction. In such a configuration, the flange abutting portions 41 may also be configured to extend along the direction in which the storage recesses 6 are arranged. Furthermore, as shown in FIG. 14, the storage recesses 6 may be arranged in a curved shape intersecting the left-right direction. Furthermore, as shown in FIG. 15, the storage recesses 6 may be arranged in multiple rows (e.g., two rows). In such a case, the flange abutting portions 41 may also be arranged in multiple rows. Furthermore, as shown in FIG. 16, the storage recesses 6 may be arranged linearly along the front-rear direction. In such a configuration, for example, the storage recesses 6 may be arranged in the front-rear direction on the left and right sides of the device storage section 5, and the flange abutting portions 41 may extend along the direction in which the storage recesses 6 are arranged. 17, the storage recesses 6 are not limited to being arranged in a line, but may be arranged in a regular dotted pattern, such as a staggered pattern. Even with the above-described configuration, the nail treatment tools 7 can be stored comfortably and arranged regularly. Even with this arrangement, the shaft 71 is supported by the storage recess 6, and a gap is formed between the flange 72 and the front edge of the storage recess 6. This prevents the nail treatment tools 7 from moving in the nail treatment tool storage case 1, and also makes it easy to insert a finger into the gap and hook the finger on the flange 72, making it easy to grasp the nail treatment tools 7 with the fingers.

[0074] Furthermore, although the example has been described in which a single linearly extending elongated hole is formed in the storage section 3 and multiple storage recesses 6 are formed in the elongated hole, the present invention is not limited to this configuration. For example, as shown in Fig. 17, multiple circular holes may be formed in the storage section 3 and each of the circular holes may be configured as a storage recess 6, or multiple storage recesses 6 may be formed in a hole extending in an arc shape. In such a configuration, point-like flange abutment portions 41 may be provided at positions corresponding to the respective circular holes. Note that point-like flange abutment portions 41 may also be provided even when multiple storage recesses 6 are formed in the elongated hole.

[0075] Furthermore, although the storage recess 6 has been described as holding the shaft 71 by the restoring force of the abutment piece 642, the configuration is not limited to this, and the shaft 71 may be held by other configurations. For example, the storage recess 6 may be configured to include a rod-shaped body extending from the storage bottom 61 to the front side, and the rod-shaped body may be inserted into the attachment hole 71a to hold the shaft 71. Even when holding the shaft 71 by the restoring force, the width of the storage side surface 62 may be configured to be smaller than the outer diameter of the shaft 71, so that the entire storage side surface 62 elastically deforms when the shaft 71 is inserted.

[0076] Furthermore, although the rod-shaped processing tool 7C has been described as being stored with the flange 72 in contact with the storage surface 63, the present invention is not limited to this configuration. For example, the rod-shaped processing tool 7C may be stored without the flange 72 in contact with the storage surface 63 by configuring the shaft 71 of the rod-shaped processing tool 7C to be shorter than the distance from the storage bottom 61 in the storage recess 6 to the storage surface 63, or by making the flange abutment portion 41 able to abut against the flange 72. In such a configuration, the flange 72 is spaced from the front side of the storage surface 63, making it easy to grasp the flange 72 with the fingers.

[0077] Furthermore, although the case where the lengths of the shaft portions 71 of the large-diameter processing tool 7A and the small-diameter processing tool 7B are different has been described, this is not limiting and the shaft portions 71 may be the same length. In such a case, for example, if the length of each shaft portion 71 is configured to be longer than the distance from the storage bottom 61 to the storage surface portion 63 of the storage recess 6, the front end of the shaft portion 71 can be positioned further outward than the storage surface portion 63 with the back end of the shaft portion 71 abutting against the storage bottom 61, so that the flange portion 72 is spaced outward from the storage surface portion 63. Furthermore, if the length of each shaft portion 71 is configured to be shorter than the distance from the storage bottom 61 to the storage surface portion 63 of the storage recess 6, the flange portion 72 will abut against the flange abutment portion 41, so that the flange portion 72 is spaced outward from the storage surface portion 63.

[0078] Furthermore, although the configuration including the flange contact portion 41 has been described as an example, it is also possible to employ a configuration that does not include the flange contact portion 41. Even in such a configuration, by making the depth of the storage recess 6 shorter than the length of the shaft portion 71, it is possible to hold the shaft portion 71 in a state where the flange portion 72 is floating above the storage surface portion 63.
