[Modes for carrying out the invention] 【0008】 Embodiments and modifications will be described with reference to Figures 1 to 5. Note that the embodiments and modifications described below are only a part of the various embodiments of this disclosure. Furthermore, the embodiments and modifications described below can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure are achieved. It is also possible to combine the configurations of the modifications as appropriate. 【0009】 The diagrams referenced below are all schematic, and the dimensional ratios of the components shown in the diagrams do not necessarily reflect the actual dimensional ratios. 【0010】 2.Details The first and second embodiments of this disclosure will be described below. 【0011】 (1) First Embodiment The coil turning tool of the first embodiment will be described with reference to Figures 1A to 2. 【0012】 In the first embodiment, the coin spinning device 1 has a front end 11 and a rear end 12. Hereinafter, the direction in which the front end 11 and the rear end 12 are aligned will be referred to as the axial direction, the front end 11 side will refer to the front end 11 side of the coin spinning device 1 in the axial direction, and the rear end 12 side will refer to the rear end 12 side of the coin spinning device 1 in the axial direction. 【0013】 The coin spinning device 1 comprises a main body 2, an operating part 3, a spring part 4, a stopper part 5, and an operating part 6, the stopper part 5 comprising an engagement part 51 and a locking part 52. 【0014】 The main body 2 is cylindrical in shape and elongated in the axial direction. The main body 2 is composed of a cylindrical peripheral wall 21. The main body 2 has an opening (first opening 22) at the end on the tip 11 side and an opening (second opening 23) at the end on the rear end 12 side. The tip 11 side end of the main body 2 has a stopper portion 52 which constitutes the stopper portion 5. The stopper portion 52 is located on the edge of the first opening 22 and consists of two recesses 520 formed in the peripheral wall 21. Each recess 520 allows passage between the inside and outside of the peripheral wall 21 and is open toward the tip 11 side. The two recesses 520 face each other in a direction perpendicular to the axial direction, with the first opening 22 in between. The material of the main body 2 is, for example, a resin material or a metal. 【0015】 The working part 3 has a shaft portion 31 and a holding portion 32. The shaft portion 31 is a long rod in the axial direction. The material of the shaft portion 31 is, for example, a resin material or metal. The shaft portion 31 is inserted into the main body portion 2, and the end of the shaft portion 31 on the rear end 12 side protrudes from the second opening 23 of the main body portion 2 toward the rear end 12 side. 【0016】 The holding portion 32 extends from the tip 11 end of the shaft portion 31 toward the tip 11 and protrudes outward from the first opening 22 to the outside of the main body portion 2. The material of the holding portion 32 is, for example, a resin material or metal. In the first embodiment, the holding portion 32 is a separate member from the shaft portion 31 and is fixed to the tip 11 end of the shaft portion 31. The holding portion 32 comprises two clamping pieces 321. The end of each clamping piece 321 toward the rear end 12 is fixed to the tip 11 end of the shaft portion 31. The two clamping pieces 321 face each other in directions perpendicular to the axial direction. Each clamping piece 321 is curved in an arc shape so as to bulge toward opposite sides of each other. The maximum distance between the two clamping pieces 321 is longer than the diameter of the coin 7 held in the holding portion 32. That is, the holding portion 32 holds a coin 7 having a diameter shorter than the maximum distance between the two clamping pieces 321. 【0017】 Two cover portions 322 are fixed to each clamping piece 321. That is, the holding portion 32 includes four cover portions 322. In each clamping piece 321, the two cover portions 322 face each other at an interval in a direction orthogonal to both the axial direction and the direction in which the two clamping pieces 321 face each other. The clamping piece 321 is sandwiched between the two cover portions 322, and is arranged so as to protrude from the clamping piece 321 to another clamping piece 321 where these clamping pieces 321 are fixed. 【0018】 The operating portion 3 is rotatable about the axis and movable in the axial direction with respect to the main body portion 2. 【0019】 An engaging portion 51 constituting the stopper portion 5 is fixed to the end portion on the tip 11 side of the shaft portion 31 in the operating portion 3. The engaging portion 51 is in the shape of a long bar in a direction orthogonal to the axial direction, and the two end portions of the engaging portion 51 protrude from the end portion of the shaft portion 31 in opposite directions in the direction orthogonal to the axial direction. 【0020】 The engaging portion 51 and the engaging stop portion 52 constitute the stopper portion 5. That is, the stopper portion 5 includes the engaging portion 51 and the engaging stop portion 52. The engaging portion 51 is arranged on the tip 11 side with respect to the engaging stop portion 52, and moves axially with respect to the engaging stop portion 52 as the operating portion 3 moves axially. When the engaging portion 51 abuts against the engaging stop portion 52 from the tip 11 side, the two end portions of the engaging portion 51 are respectively fitted into the two recesses 520 in the engaging stop portion 52. Thereby, the stopper portion 5 is in an engaged state where the engaging portion 51 and the engaging stop portion 52 are engaged. When in this engaged state, the stopper portion 5 restricts the rotation of the operating portion 3 about the axis with respect to the main body portion 2. When the stopper portion 5 is in the engaged state, when the operating portion 3 moves axially toward the tip 11 side and the engaging portion 51 moves toward the tip 11 side with respect to the engaging stop portion 52, the engaged state is released, that is, the restriction by the stopper portion 5 is released, and the operating portion 3 can rotate about the axis with respect to the main body portion 2. 【0021】 The spring part 4 is a coil spring. The coil spring is disposed within the main body part 2 so as to surround the shaft part 31 of the acting part 3. The end part on the rear end 12 side of the coil spring is fixed by being hooked to the end part on the rear end 12 side of the main body part 2. The end part on the front end 11 side of the coil spring is fixed to the part on the front end 11 side of the shaft part 31 of the acting part 3. For this reason, when the acting part 3 is axially rotated with respect to the main body part 2, an elastic force that attempts to axially rotate the acting part 3 in the reverse direction of the aforesaid axial rotation is generated in the spring part 4. 【0022】 The inner diameter of the coil spring is larger than the outer diameter of the shaft part 31. Further, the inner diameter of the coil spring is adjusted so as to coincide with the outer diameter of the shaft part 31 when the acting part 3 is axially rotated a proper number of times with respect to the main body part 2 so as to compress the coil spring. Thereby, the number of axial rotations of the acting part 3 can be regulated, and the acting part 3 can be prevented from being axially rotated excessively. For example, the inner diameter of the coil spring and the outer diameter of the shaft part 31 are adjusted so that the number of axial rotations of the acting part 3 is regulated to 4.5 rotations. 【0023】 The main body part 2 has a locking part 24 that projects from the inner surface of the peripheral wall 21. The locking part 24 is positioned below the spring part 4. When the spring part 4 attempts to move to the front end 11 side, the movement of the spring part 4 to the front end 11 side is regulated by the end part on the front end 11 side of the spring part 4 abutting against the locking part 24. Since the spring part 4 is fixed to the acting part 3, the movement of the acting part 3 to the front end 11 side is also regulated. For this reason, the acting part 3 is prevented from coming off the main body part 2. 【0024】 The operating section 6 comprises a cover 61 and a push-in section 62. The cover 61 is a bottomed cylindrical shape with the tip 11 side open. A hole 63 is formed in the bottom of the cover 61, penetrating the cover 61 axially. The push-in section 62 is a bottomed cylindrical shape with the tip 11 side open. The push-in section 62 is attached to the cover 61 so as to pass through the hole 63 of the cover 61 and is movable axially relative to the cover 61. The cover 61 is attached to the end of the main body 2 on the rear end 12 side so as to close the second opening 23. The rear end 12 side of the shaft 31 of the operating section 3 is fixed to the push-in section 62 with the rear end 12 side inserted into it. Therefore, when the user pushes the push-in section 62 toward the tip 11 side, the push-in section 62 moves toward the tip 11 side, and the operating section 3 moves toward the tip 11 side accordingly. The operating unit 6 releases the restriction by the stopper unit 5 in response to external operation. That is, when the stopper unit 5 is engaged, if the push-in unit 62 is pushed toward the tip 11 in response to external operation, the operating unit 3 moves toward the tip 11 as the push-in unit 62 moves, and as a result the engaging unit 51 moves toward the tip 11 relative to the locking unit 52, thereby releasing the engaged state. 【0025】 When the stopper portion 5 is engaged, the rear end 12 side portions of the two clamping pieces 321 are pushed into the main body portion 2 from the first opening 22, and a force is applied to the two clamping pieces 321 from the edge of the first opening 22 in a direction that brings them closer together. This narrows the maximum distance between the two clamping pieces 321. When the action portion 3 moves axially toward the tip 11 side relative to the main body portion 2 and the engagement is released, no force is applied to the two clamping pieces 321 from the edge of the first opening 22, and the distance between the two clamping pieces 321 widens and returns to its original position. 【0026】 When a user spins a coin 7 using the coin spinning tool 1, the user first places the coin 7 between the two clamping pieces 321 in the holding part 32 with the engagement released. The coin 7 is positioned so as to be sandwiched between the two cover parts 322 fixed to each clamping piece 321. In this state, the user rotates the working part 3 axially relative to the main body 2, generating an elastic force in the spring part 4 that attempts to rotate the working part 3 axially in the opposite direction to the aforementioned axial rotation. In this state, the user moves the working part 3 toward the rear end 12 side relative to the main body 2, engaging the stopper part 5, which restricts the axial rotation of the working part 3 relative to the main body 2. In this engaged state, force is applied to the two clamping pieces 321 from the edge of the first opening 22, narrowing the distance between the two clamping pieces 321, and the coin 7 is sandwiched between the two clamping pieces 321. At this time, the coin 7 is held securely by being sandwiched between the two cover portions 322 fixed to each clamping piece 321. 【0027】 Next, the user holds the coin spinning device 1 above any upward-facing surface (target surface), such as the ground, floor, or tabletop, with the tip 11 pointing downwards and the rear end 12 pointing upwards. In this state, the user operates the operating part 6. Specifically, the user presses the push-in part 62 of the operating part 6, moving it axially toward the tip 11, releasing the engagement and releasing the restriction by the stopper part 5. As a result, the elastic force applied from the spring part 4 causes the working part 3 to rotate axially, causing the coin 7 to rotate as well. At the same time, the force applied to the gripping piece 321 from the edge of the first opening 22 of the main body part 2 is released, widening the gap between the gripping pieces 321 and causing the coin 7 to fall out of the holding part 32. The coin 7 that has fallen out of the holding part 32 falls toward the target surface while rotating, and spins on the target surface like a top. 【0028】 As described above, the user can use the coin spinning device 1 to spin the coin 7 on the target surface like a top. 【0029】 (2) Second embodiment The coin spinning device 1 of the second embodiment will be described with reference to Figures 3 to 5. The coin spinning device 1 of the second embodiment differs from the first embodiment in the configuration of the interlocking portion 51 and the locking portion 52 of the stopper portion 5, but otherwise has the same configuration as the first embodiment. In the following, components that are the same as those of the first embodiment will be denoted by the same reference numerals as in the first embodiment in the drawings, and their descriptions will be omitted as appropriate. 【0030】 The meshing portion 51 has a disc-shaped base portion 511 having an axial thickness and a plurality of protrusions 512. A hole 513 is formed in the base portion 511 that penetrates the base portion 511 in the axial direction. The plurality of protrusions 512 are arranged in a line along the outer circumference of the base portion 511, surrounding the center of the base portion 511. Each protrusion 512 projects from the base portion 511 toward the rear end 12 in the axial direction. The shaft portion 31 of the working portion 3 passes through the hole 513 of the meshing portion 51, and in this state the meshing portion 51 is fixed to the shaft portion 31. The meshing portion 51 is positioned toward the rear end 12 than the spring portion 4. 【0031】 The locking portion 52 has a disc-shaped base portion 521 having an axial thickness and a cylindrical portion 526. The base portion 521 has a hole 523 that penetrates the base portion 521 in the axial direction. The cylindrical portion 526 is cylindrical and protrudes from the outer circumference of the base portion 521 toward the tip 11. The cylindrical portion 526 has a plurality of recesses 522, the same number as the convex portion 512. Each recess 522 is a notch shape with the tip 11 side open, and the plurality of recesses 522 are arranged along the outer circumference of the base portion 521 so as to surround the center of the base portion 521. Each recess 522 has a shape that matches the convex portion 512. 【0032】 The locking portion 52 is fixed to the main body 2 at a position inside the main body 2, below the spring portion 4 and above the engaging portion 51. The locking portion 52 has two screw holes 524 that open to its outer surface, and the peripheral wall 21 of the main body 2 has through holes 25 corresponding to the two screw holes 524. The locking portion 52 is fixed to the main body 2 by passing screws 525 through the through holes 25 and screwing them into the screw holes 524. 【0033】 When a user spins a coin 7 using the coin spinning tool 1, the user first places the coin 7 between the two clamping pieces 321, as in the first embodiment, and rotates the working part 3 axially relative to the main body 2, thereby generating an elastic force in the spring part 4 that causes the working part 3 to rotate axially in the opposite direction to the aforementioned axial rotation. In this state, the user moves the working part 3 toward the rear end 12 side relative to the main body 2, and fits the multiple protrusions 512 of the meshing part 51 into the multiple recesses 522 of the locking part 52 (see Figures 4A, 4B, and 5). As a result, the meshing part 51 abuts against the locking part 52 from the tip 11 side, and the meshing part 51 and the locking part 52 engage, causing the stopper part 5 to enter a meshed state. This meshed state restricts the axial rotation of the working part 3 relative to the main body 2. In this engaged state, force is applied to the two clamping pieces 321 from the edge of the first opening 22, narrowing the distance between the two clamping pieces 321, and the coin 7 is held between the two clamping pieces 321. The coin 7 is held stably because it is sandwiched between the two cover portions 322 fixed to each clamping piece 321. 【0034】 Then, as in the first embodiment, the user can position the coin spinning device 1 above the target surface and operate the operating unit 6 to release the engagement, thereby causing the coin 7 to spin like a top on the target surface. 【0035】 (3) Variant In the first and second embodiments, the shaft portion 31 and the holding portion 32 are separate components, with the holding portion 32 fixed to the shaft portion 31; however, the shaft portion 31 and the holding portion 32 may be integrally molded. In this case, the working portion 3 may be a single component. In this case, the material of the working portion 3 may be, for example, metal or resin. 【0036】 In the first and second embodiments, the coin 7 is held in the holding portion 32 by a force applied to the two clamping pieces 321 from the edge of the first opening 22 when the stopper portion is engaged. However, the coin 7 may also be held by an elastic force applied from the two clamping pieces 321. In this case, for example, the maximum distance between the two clamping pieces 321 is formed to be smaller than the diameter of the coin 7, and when the coin 7 is placed between the two clamping pieces 321, the two clamping pieces 321 deform and the distance between them widens. This generates an elastic force in each of the two clamping pieces 321, and the coin 7 may be held by this elastic force. In this case, when the engagement is released, the distance between the two clamping pieces 321 widens due to the impact and centrifugal force generated by the rotation of the holding portion 32, causing the coin 7 to fall out of the holding portion 32. 【0037】 In this embodiment, the holding portion 32 includes a cover portion 322, but it does not have to include a cover portion 322. In this case, for example, each clamping piece 321 may have a groove into which the outer circumference of the coin 7 is fitted. In this case, when the coin 7 is clamped by the clamping piece 321, the outer circumference of the coin 7 is fitted into the groove, thereby allowing the coin 7 to be held stably. 【0038】 Furthermore, the configuration of the stopper portion 5 is not limited to the first and second embodiments. The configuration of the meshing portion 51 and the locking portion 52 may be any as long as the axial rotation of the operating portion 3 relative to the main body portion 2 is restricted when the meshing state is reached. In addition, the stopper portion 5 may be any other configuration that restricts the axial rotation of the operating portion 3 relative to the main body portion 2, and that is released when the operating portion 6 is operated. The operating portion 6 may also have an appropriate structure depending on the configuration of the stopper portion 5. 【0039】 The spring portion 4 is a coil spring in the first and second embodiments, but it can be any spring as long as it can apply an elastic force that causes the working portion 3 to rotate axially. 【0040】 3.
