Description

[Technical Field]

[0001] The present disclosure relates to an irregularity amplification tool. [Background technology]

[0002] Conventionally, there is known a technique for amplifying the sensitivity of an object, such as a user's finger, to the unevenness of the surface of an object when the object traces the unevenness of the surface. For example, Patent Document 1 discloses an unevenness amplifying member and an unevenness detection method that can more appropriately amplify the user's tactile sensation to the unevenness of the object. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7233649 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the unevenness amplification member and the unevenness detection method described in Patent Document 1, the unevenness amplification member is not attached to the user's finger, so when the user uses the unevenness amplification member to detect the uneven shape of the object to be inspected, there is a possibility that the unevenness amplification member may slip off the user's finger.

[0005] When the surface of the object to be inspected is the side or ceiling of the object, the user needs to hold the unevenness amplifier between their finger and the object. This requires the user to align the unevenness amplifier with the finger using another finger on the same hand as the one using the unevenness amplifier or the finger on the opposite hand from the one using the unevenness amplifier. Even while observing the uneven shape of the surface to be inspected, the user needs to constantly press the object via the unevenness amplifier to prevent the unevenness amplifier from falling off the finger. Therefore, using the unevenness amplifier places a heavy burden on the user, which can lead to fatigue.

[0006] The present disclosure aims to provide an unevenness amplification tool that can reduce the burden on the user when using an unevenness amplification member. [Means for solving the problem]

[0007] The unevenness amplification tool for solving the above problems is as follows: an amplifying member that amplifies the sensitivity of a target that traces the uneven surface of an object to the uneven surface; a fixing member for positioning the amplifying member relative to the target while maintaining the deforming function of the amplifying member for amplifying the sensitivity; Equipped with. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to provide an unevenness amplification tool that can reduce the burden on the user when using an unevenness amplification member. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, one embodiment of the present disclosure will be mainly described with reference to the accompanying drawings.

[0011] (First embodiment) FIG. 1 is a schematic diagram showing an unevenness amplification tool 1 according to a first embodiment of the present disclosure. FIG. 1 is an enlarged schematic view of the tip side of a user's finger F tracing the surface S of an object OB to be inspected to detect an uneven shape C on the surface S. In FIG. 1, a concave shape is shown as an example of the uneven shape C, but this is not limiting. The uneven shape C may also be a convex shape. FIG. 2 is a schematic diagram showing a first example of the configuration of one surface of the unevenness amplification tool 1 of FIG. 1. FIGS. 1 and 2 show a first example of the configuration of the unevenness amplification tool 1.

[0012] The unevenness amplification tool 1 is worn by a user who intends to detect the uneven shape C of the surface S of an object OB. In this disclosure, the "object OB" includes, for example, an object to be inspected when a user uses the unevenness amplification tool 1 to inspect the uneven state of the surface S. The object OB may include any object made of metal, synthetic resin, rubber, etc. For example, the object OB includes painted automobile parts, painted parts of other transportation equipment, molds used in injection molding and press processing, and other industrial products. The "surface S of the object OB" includes, for example, the painted surface of the object OB. The "uneven shape C" refers, for example, to the shape of the concave or convex parts of the surface S of the object OB relative to a reference plane.

[0013] The unevenness amplification tool 1 is used to inspect painted products such as automobiles and transportation equipment for paint blister marks, bumps, and dents, inspect unevenness in molds used in injection molding and press working, and inspect the surface condition of other industrial products. The unevenness amplification tool 1 may also be used, for example, to detect surface distortion in steel plates and to inspect surfaces during metal surface treatment. The unevenness amplification tool 1 may also be used to detect minute uneven shapes C in which the height dimension of the tip of a convex portion or the bottom end of a concave portion relative to a reference plane on the surface S of the object OB is on the order of microns. However, the unevenness amplification tool 1 may also be used to detect uneven shapes C with a height of 1 mm or more.

[0014] For example, a user wears the unevenness amplification tool 1 on the index finger F of a hand, which is a part of the user's body, and traces the surface S of an object OB with the index finger F. The user places an amplification member 10, which will be described later, between the surface S of the object OB and the index finger F, and moves the index finger F and the amplification member 10 along the surface S of the object OB. When the amplification member 10 comes into contact with the uneven shape C of the surface S of the object OB, the amplification member 10 is deformed. At this time, the user who is touching the amplification member 10 by wearing the unevenness amplification tool 1 feels an amplified tactile sensation compared to the tactile sensation of the uneven shape C that would be felt if the user were to directly trace the surface S of the object OB.

[0015] The unevenness amplification tool 1 amplifies the user's tactile sensation to the uneven shape C. The unevenness amplification tool 1 has an amplification member 10 that amplifies the sensitivity of an object tracing the uneven shape C on the surface S of the object OB to the uneven shape C. In this disclosure, the "object" includes, for example, a part of the user's body. The "part of the body" includes, for example, a finger F of the hand. "Sensitivity" means, for example, the degree of tactile sensation the user gets from the uneven shape C.

[0016] The amplifying member 10 is configured to be elastically deformable when it moves over the surface S due to the movement of an object tracing the surface S of the object OB and encounters the uneven shape C. The amplifying member 10 may include, for example, a metal coil spring such as that used in the prior art described in Patent Document 1. Metals used for the coil spring include, but are not limited to, hard steel wire, piano wire, stainless steel wire, silicon chrome steel oil-tempered wire, and Mn-Cr steel hot-formed spring material. Alternatively, the amplifying member 10 may be made of a resin. Examples of resins include, but are not limited to, polyethylene terephthalate (PET), polyacetal, polycarbonate, ABS (Acrylonitrile-Butadiene-Styrene) resin, polyester, nylon, polypropylene, polyvinyl chloride, and acrylic.

[0017] The unevenness amplification tool 1 has a fixing member 20 that positions the amplification member 10 relative to the object while maintaining the deformation function of the amplification member 10 to amplify the sensitivity of the object tracing the uneven shape C to the uneven shape C. In the present disclosure, the "deformation function of the amplification member 10" includes, for example, a function of changing shape when the amplification member 10 moves over the surface S of the object OB due to the action of the object tracing the surface S and approaches the uneven shape C. The fixing member 20 includes, for example, tape, adhesive, a pressure-sensitive adhesive sheet, glue, etc.

[0018] The unevenness amplification tool 1 has a wearing body 30 to which an amplifying member 10 is attached by a fixing member 20. The wearing body 30 is to be worn by a subject. Examples of the wearing body 30 include finger cots, gloves, and work gloves. Examples of gloves include plastic gloves, rubber gloves, sewn gloves, and knitted gloves. The wearing body 30 may be made of, for example, thin and elastic rubber. In the example shown in FIG. 1, the wearing body 30 is worn on the index finger F of the hand of a user as a subject.

[0019] The unevenness amplification tool 1 has a first string 40 that is inserted through a through-hole 11 of an amplifying member 10 and has both ends fixed by fixing members 20. One end of the first string 40 is fixed by the fixing member 20 at a first fixing portion 41 on the surface of the attachment 30, and the other end is fixed by the fixing member 20 at a second fixing portion 42. With the first fixing portion 41 and the second fixing portion 42 fixed on the surface of the attachment 30 by the fixing member 20, the first string 40 positions the amplifying member 10 along the first string 40 between the first fixing portion 41 and the second fixing portion 42. The first string 40 may or may not have elasticity so as to be stretchable and contractible.

[0020] The unevenness amplification tool 1 has a protective sheet 50 that is placed on the amplifying member 10 at a portion that faces the surface S of the object OB when a user wears the unevenness amplification tool 1 and traces the surface S of the object OB. The protective sheet 50 is made of, for example, tape, resin, nonwoven fabric, woven fabric, rubber, paper, etc. However, when the protective sheet 50 is made of rubber, it is preferable that a predetermined coating is applied to the rubber to reduce friction with the surface S and make it easier to slide when a user wears the unevenness amplification tool 1 and traces the surface S. In the present disclosure, "sheet" means that it is formed, for example, in the form of a film, membrane, foil, etc.

[0021] As shown in FIG. 1 , the protective sheet 50 is disposed between the amplifying member 10 and the surface S, and moves in accordance with the movement of the index finger F and the amplifying member 10. The protective sheet 50 protects the surface S from being scratched by contact with the amplifying member 10 when a user wears the unevenness amplification tool 1 and traces the surface S. The protective sheet 50 may be a thin, hard sheet that is elastically deformable. The protective sheet 50 has flexibility and pliability to the extent that it can deform along the uneven shape C of the surface S of the object OB.

[0022] 1 and 2, the amplifying member 10 of the unevenness amplifying tool 1 is arranged relative to the target so that its position can be changed relative to the target. For example, the amplifying member 10 is arranged on the finger pad side of the index finger F of the user's hand, which is the target. In this case, the amplifying member 10 is arranged so that its position can be changed relative to the finger pad of the index finger F. The amplifying member 10 is not fixed to the surface of the wearing body 30, and is movable on the surface of the wearing body 30 within a predetermined range when not pressed against the surface S of the object OB.

[0023] The position of the amplifying member 10 can be changed along the first string 40. For example, the amplifying member 10 can move along the first string 40 between both ends of the first string 40, which is fixed by the fixing member 20 on the surface of the attachment 30. The movement of the amplifying member 10 along the first string 40 is restricted by the first string 40 being inserted through the through-portion 11 of the amplifying member 10. On the other hand, the amplifying member 10 can move on the surface of the attachment 30 along the first string 40 within a range between the first fixing portion 41 and the second fixing portion 42 of the first string 40, which are fixed by the fixing member 20.

[0024] Fig. 3 is a schematic diagram showing a second example of the configuration of one surface of the unevenness amplification tool 1 in Fig. 1. Fig. 3 shows a schematic diagram of a second example of the configuration of the unevenness amplification tool 1. In the first example shown in Figs. 1 and 2, the unevenness amplification tool 1 has a first string 40 that is inserted into the through-hole 11 of the amplification member 10 and has both ends fixed by fixing members 20, but the unevenness amplification tool 1 is not limited to this.

[0025] In a second example shown in FIG. 3 , the irregularity amplification tool 1 may have second strings 60, instead of the first strings 40, each of which has one end connected to each end of the amplifying member 10 and the other end fixed by a fixing member 20. The second strings 60 include one second string 60a connected to one end of the amplifying member 10 and another second string 60b connected to the other end of the amplifying member 10. One end of the second string 60a is connected to one end of the amplifying member 10 on the surface of the attachment 30, and the other end is fixed by the fixing member 20 at a first fixing portion 61. The second string 60b is connected to the other end of the amplifying member 10 on the surface of the attachment 30, and the other end is fixed by the fixing member 20 at a second fixing portion 62. The second string 60 positions the amplifying member 10 so that it is sandwiched between the second strings 60a and 60b and the first fixing portion 61 and the second fixing portion 62. The second string 60 may have elasticity so that it can be stretched and contracted, or it may not have elasticity.

[0026] 3, the amplifying member 10 of the unevenness amplifying tool 1 is also arranged relative to the target so that its position can be changed relative to the target. For example, the amplifying member 10 is arranged on the finger pad side of the index finger F of the user's hand, which is the target. In this case, the amplifying member 10 is arranged so that its position can be changed relative to the finger pad of the index finger F. The amplifying member 10 is not fixed to the surface of the wearing body 30, and is movable on the surface of the wearing body 30 within a predetermined range when not pressed against the surface S of the object OB.

[0027] The position of the amplifying member 10 may be variable, for example, by the flexure or expansion / contraction of the second string 60. For example, the amplifying member 10 may be movable while sandwiched between the second strings 60a and 60b that are fixed on the surface of the attachment 30 by the fixing member 20. Since both ends of the amplifying member 10 are connected to the second strings 60a and 60b, respectively, the movement of the amplifying member 10 is limited within the region sandwiched between the second strings 60a and 60b, which is based on the flexure, expansion / contraction, etc. of the second strings 60a and 60b. On the other hand, the amplifying member 10 is movable on the surface of the attachment 30 relative to the second string 60 within the region sandwiched between the second strings 60a and 60b that are fixed by the fixing member 20.

[0028] Fig. 4 is a schematic diagram showing a third example of the configuration of one surface of the unevenness amplification tool 1 of Fig. 1. Fig. 4 shows a schematic diagram of a third example of the configuration of the unevenness amplification tool 1. In the first and second examples shown in Figs. 1 to 3, the surface of the mounting body 30 of the unevenness amplification tool 1 is formed continuously without any notches or the like, but is not limited to this.

[0029] In a third example shown in Fig. 4, the mounting body 30 of the unevenness amplification tool 1 may have a slit 31 formed in the portion where the amplification member 10 is disposed. When a user wears the unevenness amplification tool 1 and traces the surface S, the amplification member 10 is pressed against the surface S of the object OB, and the amplification member 10 comes into direct contact with the pad of the user's index finger F exposed from the slit 31. When a user wears the unevenness amplification tool 1 and traces the surface S, and presses the amplification member 10 against the surface S of the object OB, the user directly feels the contact of the amplification member 10 with the pad of their index finger F via the slit 31 in the mounting body 30.

[0030] Fig. 5 is a schematic diagram showing a fourth example of the configuration of one surface of the irregularity amplification tool 1 in Fig. 1. Fig. 5 shows a schematic diagram of the fourth example of the configuration of the irregularity amplification tool 1. In the first to third examples shown in Figs. 1 to 4, the irregularity amplification tool 1 has been described as having only one amplification member 10, but is not limited to this.

[0031] 5, the unevenness amplification tool 1 may have a plurality of amplifying members 10. The plurality of amplifying members 10 may be attached to the same surface of the wearing body 30. For example, the plurality of amplifying members 10 may be attached to the bottom surface of the wearing body 30 located on the finger pad side of the user's index finger F when the wearing body 30 is worn by the user. As an example, two amplifying members 10 may be attached to the bottom surface of the wearing body 30 so as to be parallel to each other.

[0032] 2, a first string 40 and a protective sheet 50 are arranged for each of the two amplifying members 10. Each of the two first strings 40 is fixed by the fixing member 20 at the first fixing portion 41 and the second fixing portion 42. With each of the two first strings 40 fixed by the fixing member 20 on the bottom surface of the attachment 30, the amplifying member 10 is positioned along the first string 40 between the first fixing portion 41 and the second fixing portion 42.

[0033] The multiple amplifying members 10 included in the unevenness amplifying tool 1 may have different magnifications for amplifying the sensitivity of an object tracing the uneven shape C on the surface S of the object OB to the uneven shape C. In the present disclosure, the "magnification factor for amplifying sensitivity" includes, for example, the amplification factor for the sensitivity to the uneven shape C amplified by the amplifying member 10, when the sensitivity when an object traces the uneven shape C without using the unevenness amplifying tool 1 is used as a reference. The magnification factor for amplifying sensitivity can be adjusted depending on the spring characteristics of the amplifying member 10, including, for example, the shape, length, width, wire diameter, elastic modulus, and number of turns of the spring.

[0034] Fig. 6 is a schematic diagram showing a fifth example of the configuration of the irregularity amplification tool 1 of Fig. 1. In the fourth example shown in Fig. 5, the irregularity amplification tool 1 has multiple amplification members 10 on the same surface of the mounting body 30, but is not limited to this.

[0035] 6, the multiple amplifying members 10 of the unevenness amplifying tool 1 may be attached to different surfaces of the wearing body 30. For example, when the wearing body 30 is worn by a user, the multiple amplifying members 10 may be attached to at least two of the following: the top surface of the wearing body 30 located on the dorsum side of the user's index finger F; the bottom surface of the wearing body 30 located on the pad side of the user's index finger F; and the side surfaces located between the top and bottom surfaces. As an example, three amplifying members 10 may be attached to the top surface, bottom surface, and side surface of the wearing body 30, respectively.

[0036] 2, a first string 40 and a protective sheet 50 are arranged for each of the three amplifying members 10. Each of the three first strings 40 is fixed by the fixing member 20 at the first fixing portion 41 and the second fixing portion 42. With the first fixing portion 41 and the second fixing portion 42 fixed by the fixing member 20, the three first strings 40 position the amplifying members 10 along the first strings 40 between the first fixing portion 41 and the second fixing portion 42 on the top, bottom, and side surfaces of the attachment 30, respectively.

[0037] As in the fourth example shown in FIG. 5 , the multiple amplifying members 10 included in the unevenness amplifying tool 1 may have different magnifications for amplifying the sensitivity of the target to the uneven shape C of the surface S of the object OB when tracing the uneven shape C. For example, the magnification for amplifying the sensitivity may be adjusted for each of the three amplifying members 10 arranged on the top, bottom, and side surfaces of the wearing body 30, respectively, depending on the tactile sensitivity of the dorsum, pad, and side surface of the user's index finger F. For example, if the pad of the user's index finger F is the most sensitive to touch among the dorsum, pad, and side surface of the user's index finger F, the magnification for amplifying the sensitivity of the amplifying member 10 arranged on the bottom surface of the wearing body 30 may be adjusted to the lowest. On the other hand, if the dorsum of the user's index finger F is the least sensitive to touch among the dorsum, pad, and side surface of the user's index finger F, the magnification for amplifying the sensitivity of the amplifying member 10 arranged on the top surface of the wearing body 30 may be adjusted to the highest.

[0038] The unevenness amplification tool 1 according to the first embodiment described above can reduce the burden on the user when using the unevenness amplification member, i.e., the amplification member 10. In addition to the amplification member 10, the unevenness amplification tool 1 has a fixing member 20 that positions the amplification member 10 relative to the target while maintaining the deformation function of the amplification member 10 to amplify the sensitivity of the target to the uneven shape C. Stable positioning of the amplification member 10 relative to the target by the fixing member 20 reduces positional deviation of the amplification member 10 relative to the target when the target traces the uneven shape C of the surface S of the object OB.

[0039] Even when the surface S of the object OB to be inspected is the side or ceiling surface of the object OB, the user does not need to consciously pinch the amplification member 10 between his / her finger F and the object. For example, the user does not need to use other fingers on the same side of the hand using the unevenness amplification tool 1 or fingers on the opposite hand to the hand using the unevenness amplification tool 1 to align the amplification member 10 with the finger F. Even while observing the uneven shape C of the surface to be inspected, the user does not need to hold the amplification member 10 with other fingers on the same side of the hand using the unevenness amplification tool 1 or fingers on the opposite hand to the hand using the unevenness amplification tool 1. Therefore, the burden on the user when using the amplification member 10 is small, and physical fatigue of the user is reduced.

[0040] The amplification member 10 is placed relative to the object so that its position can be changed relative to the object. This allows the amplification member 10 to easily maintain its own deformation function when detecting the uneven shape C without being strongly fixed to the object. Therefore, the effect of amplifying the sensitivity to the uneven shape C is maintained without interfering with the deformation function of the amplification member 10. In addition, the user can position the amplification member 10 at the position where the tactile sense is most sensitive for each object on which the amplification member 10 is placed. The unevenness amplification tool 1 also allows the position of the amplification member 10 relative to the object to be fine-tuned for each different user, making it usable by any user.

[0041] The irregularity amplification tool 1 further includes a first string 40 that is inserted through the through-hole 11 of the amplification member 10 and has both ends fixed by fixing members 20. The position of the amplification member 10 can be changed along the first string 40. This allows the amplification member 10 to easily maintain its deformation function when detecting the irregular shape C without being strongly fixed to the target. Therefore, the effect of amplifying the sensitivity to the irregular shape C is maintained without interfering with the deformation function of the amplification member 10. In addition, the user can position the amplification member 10 along the first string 40 to the position where the tactile sense is most sensitive for each target on which the amplification member 10 is placed. The irregularity amplification tool 1 also allows the position of the amplification member 10 relative to the target to be fine-tuned along the first string 40 for each user, making it usable by any user.

[0042] The irregularity amplification tool 1 further includes a second string 60, one end of which is connected to each end of the amplifying member 10 and the other end of which is fixed by the fixing member 20. The position of the amplifying member 10 can be changed by the deflection of the second string 60. This allows the amplifying member 10 to easily maintain its deformation function when detecting the irregular shape C without being strongly fixed to the object. Therefore, the effect of amplifying the sensitivity to the irregular shape C is maintained without interfering with the deformation function of the amplifying member 10. In addition, the second string 60 allows the user to position the amplifying member 10 at the position where the tactile sense is most sensitive for each object on which the amplifying member 10 is placed. The irregularity amplification tool 1 also allows the position of the amplifying member 10 relative to the object to be fine-tuned for each user using the second string 60, making it usable by any user.

[0043] The unevenness amplification tool 1 has a wearing body 30 to which an amplifying member 10 is attached by a fixing member 20, and the wearing body 30 is worn by a target. This improves the ease with which the unevenness amplification tool 1 is worn by the target. A user can easily position the amplifying member 10 by wearing the wearing body 30 on their finger F, for example. The amplifying member 10 is stably positioned relative to the target by the fixing member 20 in the wearing body 30, thereby reducing positional deviation of the amplifying member 10 relative to the target when the target traces the uneven shape C of the surface S of the object OB.

[0044] Even when the surface S, which is the test surface of the object OB to be tested, is the side or ceiling surface of the object OB, the user does not need to consciously pinch the amplification member 10 between his / her finger F and the test object. For example, the user does not need to use other fingers on the same side of the hand wearing the attachment 30 of the unevenness amplification tool 1 or fingers on the opposite hand to the hand wearing the attachment 30 to align the amplification member 10 with the finger F. Even while observing the uneven shape C of the test surface, the user does not need to hold the amplification member 10 with other fingers on the same side of the hand wearing the attachment 30 or fingers on the opposite hand to the hand wearing the attachment 30. Therefore, the burden on the user when using the amplification member 10 is small, and physical fatigue of the user is reduced.

[0045] The wearing body 30 has a slit 31 formed in the portion where the amplifying member 10 is disposed. This allows the unevenness amplification tool 1 to bring a portion of the object to which the wearing body 30 is attached into direct contact with the amplifying member 10. When a user wears the unevenness amplification tool 1 and traces the surface S, the user can press the amplifying member 10 against the surface S of the object OB, and directly feel the contact of the amplifying member 10 with the pad of their index finger F through the slit 31 in the wearing body 30. This improves the effect of amplifying the sensitivity to the uneven shape C by the amplifying member 10. In addition, even if the wearing body 30 is a thick glove or work glove, the method of attaching the amplifying member 10 to the object, such as that shown in Figures 2 and 3, can be applied.

[0046] Multiple amplification members 10 are attached to the same surface of the attachment 30. This increases the area over which the amplification members 10 are arranged relative to the object. Therefore, when a user wears the unevenness amplification tool 1 and traces the surface S once, the detectable area of ​​the unevenness amplification tool 1 for the uneven shape C on the surface S of the object OB increases. Therefore, when a user wears the unevenness amplification tool 1 and traces the surface S of the object OB, the user can detect the uneven shape C over a wider area on the surface S in a single action.

[0047] A plurality of amplifying members 10 are attached to different surfaces of the attachment 30. This allows the unevenness amplification tool 1 to place an amplifying member 10 on each of a plurality of different surfaces of an object. By wearing the unevenness amplification tool 1 on, for example, one's index finger F, a user can place an amplifying member 10 on each of the dorsum, pad, and side of the index finger F. This increases the degree of freedom in the orientation of the object when tracing the surface S of the object OB. When tracing the surface S of the object OB to detect the uneven shape C, the user can freely determine the direction in which the index finger F as the object is directed toward the surface S, without being limited to the pad side.

[0048] The multiple amplification members 10 have different sensitivity amplification magnifications. This allows the unevenness amplification tool 1 to place amplification members 10 with various magnifications on a target. When a user wears the unevenness amplification tool 1 on, for example, their index finger F, the unevenness amplification tool 1 can also place amplification members 10 with different magnifications on the dorsum, pad, and side of the index finger F, which have different original tactile sensitivities when not wearing the unevenness amplification tool 1. For example, if the dorsum of the index finger F is most sensitive to touch among the dorsum, pad, and side of the index finger F, the user can place amplification members 10 with the lowest sensitivity amplification magnification on the bottom surface of the wearing body 30. On the other hand, if the dorsum of the index finger F is least sensitive to touch among the dorsum, pad, and side of the index finger F, the user can place amplification members 10 with the highest sensitivity amplification magnification on the top surface of the wearing body 30.

[0049] In the first embodiment, the target has been described as including, for example, a part of the user's body, but is not limited to this. The target may also include a part of a machine, such as a robot, that inspects the condition of the surface S of the object OB and detects the uneven shape C. The "part of the machine" may include, for example, a detection module that inspects the condition of the surface S of the object OB and detects the uneven shape C. The "detection module" may include, for example, a sensor such as a strain gauge. In this case, "sensitivity" may refer to, for example, the degree of output of a sensor signal that a machine, such as a robot, obtains for the uneven shape C using the detection module.

[0050] In the first embodiment, the unevenness amplification tool 1 is described as having a mounting body 30 to which the amplifying member 10 is attached by a fixing member 20 and which is mounted on an object. However, this is not limited to this. The unevenness amplification tool 1 may not have a mounting body 30. For example, the unevenness amplification tool 1 may be configured so that the amplifying member 10 is directly fixed to the object by the fixing member 20 without using the mounting body 30. For example, both ends of the amplifying member 10 may be directly fixed to the surface of the object by the fixing member 20. When the object includes a detection module of a machine such as a robot, the fixing member 20 may further include solder instead of or in addition to tape, adhesive, a pressure-sensitive adhesive sheet, glue, etc. The amplifying member 10 may be directly fixed to the surface of the detection module by solder, for example.

[0051] In the first embodiment, the fixing member 20 is described as including, for example, tape, adhesive, a pressure-sensitive adhesive sheet, glue, etc., but is not limited thereto. The fixing member 20 may also include, for example, the wearing body 30 itself. For example, the amplifying member 10 may be placed relative to the target while maintaining its deformation function for amplifying sensitivity by directly tying the first string 40 or the second string 60 to the wearing body 30, such as a finger cot, glove, or work gloves. For example, the amplifying member 10 may be placed relative to the target while maintaining its deformation function for amplifying sensitivity by tying the first string 40 or the second string 60 through a hole formed in the surface of the wearing body 30, such as a finger cot, glove, or work gloves. In this case, the first string 40 or the second string 60 may have a knot, such as a knot, formed in it, that is larger than the diameter of the hole formed in the surface of the wearing body 30.

[0052] 1 to 6, in the first embodiment, the amplifying member 10 is arranged vertically along the extension direction of the user's finger F, but is not limited to this. The amplifying member 10 may also be arranged horizontally so as to be perpendicular to the extension direction of the user's finger F.

[0053] In the first embodiment, as shown in FIG. 5, the multiple amplifying members 10 are attached in parallel to the same surface of the mounting body 30, but this is not limiting. The multiple amplifying members 10 may be attached to the same surface of the mounting body 30 in any other arrangement relationship different from the parallel arrangement. For example, the multiple amplifying members 10 may be attached obliquely to each other to the same surface of the mounting body 30. In this case, the multiple amplifying members 10 may or may not intersect with each other. The unevenness amplification tool 1 may have multiple amplifying members 10 on each of different surfaces of the mounting body 30. In this case, the arrangement relationship of the multiple amplifying members 10 may be the same on different surfaces of the mounting body 30 or may be different.

[0054] In the first embodiment, the multiple amplifying members 10 are described as having different magnifications for amplifying the sensitivity, but this is not limiting. The multiple amplifying members 10 may have the same magnification for amplifying the sensitivity.

[0055] (Second embodiment) Fig. 7 is a schematic diagram showing a first example of the configuration of one surface of an unevenness amplification tool 1 according to a second embodiment of the present disclosure. Fig. 7 shows a schematic diagram of the first example of the configuration of an unevenness amplification tool 1.

[0056] In the first embodiment, the amplifying member 10 is described as being arranged relative to the target so that its position is variable relative to the target, but this is not limited to this. The amplifying member 10 may also be arranged relative to the target so that its position is fixed relative to the target. Other configurations, functions, effects, and modifications are the same as those of the first embodiment, and the corresponding explanations also apply to the irregularity amplification tool 1 of the second embodiment. In the following, components similar to those of the first embodiment are given the same reference numerals, and their explanations will be omitted. Differences from the first embodiment will mainly be explained.

[0057] In the first example shown in FIG. 7 , the amplifying member 10 may be covered by the fixing member 20. For example, the amplifying member 10 may be directly fixed to the surface of the wearing body 30 by the fixing member 20, rather than being indirectly attached to the wearing body 30 by the first string 40 or the second string 60. Even in such a case, the amplifying member 10 is positioned relative to the object while maintaining its deformation function for amplifying sensitivity. The amplifying member 10 is not firmly fixed by the fixing member 20, but its position on the surface of the wearing body 30 is fixed to the extent that it can elastically deform when it moves over the surface S of the object OB due to the movement of the object tracing the surface S and approaches the uneven shape C.

[0058] According to the first example of the second embodiment described above, the amplifying member 10 is positioned more stably relative to the target by the fixing member 20. This further reduces the positional deviation of the amplifying member 10 relative to the target when the target traces the uneven shape C of the surface S of the object OB. Therefore, similar to the first embodiment, the unevenness amplification tool 1 can further reduce the burden on the user when using the amplifying member 10.

[0059] Fig. 8 is a schematic diagram showing a second example of the configuration of one surface of the unevenness amplification tool 1 according to the second embodiment of the present disclosure. Fig. 8 shows a schematic diagram of the second example of the configuration of the unevenness amplification tool 1. In the first example shown in Fig. 7, the amplification member 10 is covered by the fixing member 20, but the present disclosure is not limited to this.

[0060] In a second example shown in FIG. 8 , the amplifying member 10 may be fixed at both ends by the fixing members 20. For example, the amplifying member 10 may be directly fixed to the surface of the wearing body 30 by the fixing members 20, rather than being indirectly attached to the wearing body 30 by the first string 40 or the second string 60. Even in such a case, the amplifying member 10 is positioned relative to the object while maintaining its deformation function for amplifying sensitivity. The amplifying member 10 is not firmly fixed by the fixing members 20, but its position on the surface of the wearing body 30 is fixed so that it can elastically deform when it moves over the surface S of the object OB due to the movement of the object tracing the surface S and approaches the uneven shape C.

[0061] According to the second example of the second embodiment described above, the amplifying member 10 is positioned more stably relative to the target by the fixing member 20. This further reduces the positional deviation of the amplifying member 10 relative to the target when the target traces the uneven shape C of the surface S of the object OB. Therefore, similar to the first embodiment, the unevenness amplification tool 1 can further reduce the burden on the user when using the amplifying member 10.
