[Diagram 5] 13A and 13B are diagrams illustrating modified examples of the ink reducing means. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] FIG. 1 is a perspective view showing the configuration of a wire drawing tool 100. The wire drawing tool 100 comprises a wire drawing tool main body 1, a fastener 6, and a thread 3 connecting them. The fastener 6 is also called a "calco." The wire drawing tool main body 1 comprises a case 11 incorporating various structures. The case 11 has a thread winding storage section 11A, an ink chamber section 11B, and a thread reeling outlet 11D. A thread winding cover 12 is provided on the top surface of the thread winding storage section 11A as a lid. The internal space of the thread winding storage section 11A can be opened by opening the thread winding cover 12. A thread spool 2 (see FIG. 3) is stored inside the thread winding storage section 11A.

[0010] The thread 3 is wound around the thread spool 2. The thread spool 2 is provided with a biasing mechanism. As an example, a spring charger capable of engaging with the spring core of the thread spool 2 may be attached to one side of the thread spool storage section 11A. This spring charger may have a known structure, for example, consisting of a one-way clutch mechanism and a release mechanism for the clutch mechanism. The spring charger may be used to adjust the biasing force of a spiral spring built into the thread spool 2. The thread 3 is pulled out to the outside of the case 11 through the ink chamber of the ink chamber section 11B (see FIG. 3) and the thread reel-out opening 11D. A fastener 6 is attached to the tip of the thread 3.

[0011] The ink chamber 11B is a portion in which an ink chamber is provided inside. An ink chamber cover 13 is provided as a lid on the top surface of the ink chamber 11B. By opening the ink chamber cover 13, the ink chamber inside can be opened.

[0012] As shown in FIG. 1, a fastener 6 is attached to the tip of the thread 3 that is led out of the case 11. The fastener 6 includes a hollow handle 61 made of, for example, synthetic resin, and a fastener needle 62 made of, for example, metal. In the example of FIG. 1, the fastener needle 62 may be normally stored in the handle 61 by a needle-biasing spring (not shown). When using the fastener, the handle 61 is grasped with fingers and pulled away from the wire drawing tool main body 1. At this time, the fastener needle 62 is in a protruding state because the thread 3 is taut (i.e., tension is applied). When the tension of the thread 3 is released, the fastener needle 62 is stored inside the fastener 6. When the pressing piece 63 (fastener cover) is pressed, the fastener needle 62 can be kept in a protruding state even if the thread 3 is loosened. There is no limitation on the specific structure for storing / protruding the fastener needle 62. The thread reeling outlet 11D in the case 11 is provided in a funnel shape, for example (see FIG. 3). A tip 61a of the handle 61 is formed into a shape that allows it to be held in a fitted state in the yarn reeling outlet 11D.

[0013] Fig. 2 is a front view of the wire drawing tool body 1 as viewed from the yarn reel-out outlet 11D side. Fig. 3 is a cross-sectional view of the wire drawing tool body 1 taken along line AA in Fig. 2. One of the features of the wire drawing tool body 1 of the embodiment is that it includes an ink-adhering penetrating material 4A and an ink reducing means 4B.

[0014] As shown in FIG. 3, the ink chamber of the ink chamber 11B contains the ink adhesive penetrant 4A. The ink adhesive penetrant 4A is an ink penetrant material that has the property of allowing various inks to penetrate into it. As an example, the ink adhesive penetrant 4A may be a urethane-based sponge with a relatively low water retention capacity. As an example, the ink adhesive penetrant 4A is a member made of a rectangular sponge piece that is large enough to fit into the ink chamber of the ink chamber 11B. In the embodiment, among various inks, pigment ink is used as the ink for drawing lines. Therefore, the ink adhesive penetrant 4A is impregnated with pigment ink. Before use, the ink adhesive penetrant 4A in the ink chamber 11B is sufficiently impregnated with pigment ink. The ink chamber cover 13 is opened to inject pigment ink into the ink chamber 11B.

[0015] As shown in FIG. 3, in the embodiment, an ink reducing permeable material 4B is provided as the ink reducing means 4B next to the ink-adhering permeable material 4A in the ink chamber of the ink chamber section 11B. The ink reducing permeable material 4B is an ink permeable material provided for the purpose of reducing the amount of ink attached to the yarn 3. As an example, the ink reducing permeable material 4B may be a cellulose sponge with a relatively high water retention capacity. The ink reducing permeable material 4B has a size large enough to fit in the ink chamber of the ink chamber section 11B together with the ink-adhering permeable material 4A. The ink reducing permeable material 4B has various structural variations. The ink reducing permeable material 4B may be a permeable material such as a piece of sponge or a fibrous material that forms a thin layer. Alternatively, the ink reducing permeable material 4B may be a layer of permeable material that is directly formed or laminated on the surface of the ink-adhering permeable material 4A (the surface on the yarn reel-out port 11D side). The specific structure and modified examples of the ink permeable material will be described in detail later.

[0016] As an example, the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B each have a slit (notch). As an example, each slit starts from the central axis of the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B and spreads in the outer diameter direction (for example, toward the ink chamber cover 13 side, i.e., above the line drawing tool body 1). In the example of FIG. 3, slits are provided only in the upper half of each of the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B, and the lower half of each is connected. The thread 3 is inserted into the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B through the slit. The AA cross section in FIG. 3 is obtained by cutting the line drawing tool body 1 on a virtual plane that passes through the slit. For this reason, only the lower half of the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B is hatched with diagonal lines to indicate the cut surface.

[0017] The marking operation using pigment ink is also called "line drawing operation." In the line drawing operation, for example, the fastener 6 is first attached by inserting its fastener needle 62 into one of the starting points of the marking on the surface of the mating material. Then, when the line drawing tool body 1 is moved toward the other starting point of the line drawing, the thread 3 is pulled out by the movement distance of the line drawing tool body 1 while the thread spool 2 rotates. When the thread 3 is pulled out during the line drawing operation, the thread 3 moves inside the slit of the ink-adhering penetrating material 4A. During this movement, the thread 3 comes into sliding contact with the ink-adhering penetrating material 4A, so that the pigment ink adheres to the thread 3. At this time, the spiral spring built in the thread spool 2 is charged with energy as the thread spool body rotates.

[0018] The ink reducing penetrating material 4B as the ink reducing means 4B comes into sliding contact with the yarn 3 after the ink attaching penetrating material 4A does when the yarn 3 is pulled out or wound. The contact between the ink reducing penetrating material 4B and the yarn 3 allows the pigment ink attached to the yarn 3 to be reduced to an appropriate amount.

[0019] Once the case 11 has been moved to the other starting point of the line drawing, the thread 3 is hooked into the thread hooking groove 137 provided in the thread holding protrusion 136 of the line drawing tool main body 1, and the thread 3 is held down on the surface of the mating material. The thread 3 is stretched with an appropriate tension between it and the fastener 6. The thread 3 is flicked with a finger toward the surface of the mating material to strike it. A straight ink line can be transferred using the thread 3 with an appropriate amount of pigment ink attached.

[0020] After the wire drawing operation is completed, the wire drawing tool main body 1 is moved toward the fastener 6 attached to the counterpart material. The spool 2 rotates in the winding direction due to the relaxation of the spiral spring that has been energized during the process of drawing out the thread 3. The thread 3 is automatically wound onto the spool 2. Finally, when the fastener 6 is pulled out from the counterpart material, the thread 3 is further wound, and the tip 61a of the handle 61 of the fastener 6 is engaged and locked into the thread reel-out opening 11D.

[0021] The ink reduction means 4B can appropriately reduce the amount of ink adhering to the thread 3. For example, in the example of FIG. 3, if the amount of ink adhering to the drawn thread 3 is too great, the line obtained by the line drawing operation is likely to become unclear. In this regard, in the embodiment, the ink reduction means 4B adjusts the amount of ink adhering to an appropriate amount, thereby suppressing the adverse effects caused by the tendency of the thread 3 to have too much pigment ink. A novel line drawing tool 100 suitable for use with pigment ink is provided.

[0022] In the embodiment, as an example, the ink-reducing penetrating material 4B is disposed next to the ink-attaching penetrating material 4A in the ink chamber, as illustrated in Fig. 3. Since the ink-reducing penetrating material 4B (i.e., the ink reducing means 4B) can be disposed by utilizing the limited space in the ink chamber, the line drawing tool 100 can be made compact.

[0023] The ink-adhering penetrant material 4A is any penetrant material capable of containing various inks. Also, the ink-reducing penetrant material 4B (i.e., the ink reducing means 4B) can be any penetrant material capable of reducing ink adhering to the yarn 3. As an example, in the embodiment, both the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B are "ink penetrant materials." The ink penetrant material in the embodiment is any ink penetrant material capable of absorbing various inks and wiping various inks from the yarn 3.

[0024] The ink penetrating material of the embodiment may be a "synthetic resin porous body such as a resin sponge." Specifically, the synthetic resin porous body may be a urethane sponge, a cellulose sponge, or a polyvinyl alcohol sponge (also called a PVA sponge).

[0025] Urethane sponges are made by foaming synthetic resins such as polyurethane into a sponge-like form. There are three types of urethane sponges: soft, semi-rigid, and rigid, depending on the degree of foaming. Flexible urethane foam has connected air bubbles inside, is soft and resilient, and is used as cushioning material and cleaning sponges. Rigid urethane foam has independent, unconnected air bubbles inside, is elastic, and has low moisture permeability, so is used for waterproof packing. Semi-rigid urethane foam has properties between soft and rigid.

[0026] Cellulose sponges have excellent water absorption capabilities because they are made from essentially 100% natural materials, and because cellulose has hydrophilic groups (OH groups) and thus has the chemical property of being easily compatible with water. In other words, the hydrophilic groups make it compatible with water, and the microbubbles have self-absorbency due to the capillary phenomenon, allowing it to quickly absorb water. In particular, because of the open cells, almost all of the cells can absorb water, and it generally has a water absorption capacity of 20 to 30 times its own weight. It also has the characteristic of moderately retaining absorbed water and rarely running off.

[0027] PVA sponge is one of the hydrophilic resin sponges with a three-dimensional network structure with interconnected pores. PVA sponge has excellent water absorption and water retention, as well as excellent chemical resistance and abrasion resistance. Of course, other resin sponges such as polyvinyl resin interconnected pores other than PVA sponge may also be used.

[0028] The ink penetrating material of the embodiment may be a "fiber material". The fiber material may be, for example, a fabric made of natural or chemical fibers. An example of the fiber material may be, for example, a mass of entangled fibers, such as woven fabric, knitted fabric, nonwoven fabric, felt, absorbent cotton, or cosmetic cotton. The fiber material may be made of cellulose fibers that have excellent ink penetration and retention properties. The material of the fiber material may be, for example, rayon, polynosic, cupra (registered trademark), or tencel, or may be chemical fibers such as polyester, nylon, or acrylic.

[0029] 3, a plurality of ink penetrant materials having different properties (ink-adhering penetrant material 4A and ink-reducing penetrant material 4B) are arranged in the same ink chamber, and the difference in the properties of these ink penetrant materials is used to appropriately reduce the amount of ink adhering to the yarn 3. In the embodiment, these two penetrant materials are arranged in series along the direction in which the yarn 3 advances and retreats (also called the yarn path direction).

[0030] There are several methods for providing a difference in the properties of the ink penetrant materials. As described above, there are various options for the ink penetrant materials, but the following configuration may be adopted to utilize the difference in the properties of the ink penetrant materials to adjust the amount of ink.

[0031] The first method of differentiating the properties is to use the ink penetrating materials as the same material, but to make at least one of the materials and structures different. As an example, the ink penetrating materials may be made of synthetic resin porous bodies (more specifically, resin sponges) but made of different resin materials. In this case, the ink-adhering penetrating material 4A may be a "low-moisture-retaining sponge" that has low moisture retention, while the ink-reducing penetrating material 4B may be a "high-moisture-retaining, highly absorbent sponge" that has higher moisture retention and better water absorption than the ink-adhering penetrating material 4A. In this way, the ink-adhering penetrating material 4A can easily attach the pigment ink to the yarn 3, while the ink-reducing penetrating material 4B can absorb excess pigment ink from the yarn 3.

[0032] In accordance with the above example of the first method, the ink-adhering penetrating material 4A may be a urethane sponge, and the ink-reducing penetrating material 4B may be a cellulose sponge. The combination of a urethane sponge and a cellulose sponge has practical advantages such as low cost and ease of procurement. The low moisture retention sponge may be any of various urethane sponges, such as polyurethane foam, for example. The high moisture retention, highly absorbent sponge may be a PVA sponge instead of a cellulose sponge.

[0033] The second method of differentiating the properties is to use the same material as in the first method, and the ink penetrating materials may be made of the same material, and the pore structures of the ink penetrating materials may be different from each other. The pore structure is a structural parameter that affects water absorption, and includes, for example, average pore size and porosity. When the ink penetrating material has a three-dimensional network structure with continuous pores, the pore structure parameter is one of the factors that determine the difference in water absorption based on, for example, capillary action. In order to utilize the difference in water absorption based on the capillary action, two resin sponges made of the same resin material but with different porosity, etc. may be used.

[0034] The third method of creating differences in properties is to use "same material" like the first and second methods above, and multiple ink penetrating materials may both be fibrous materials. One example of the "low moisture retention type fibrous material" may be resin fiber, specifically acrylic fiber used in paint coatings. Other examples of low moisture retention type fibrous materials include cotton, cotton for cosmetics, and other cotton for various other uses. One example of the "high moisture retention type highly absorbent fibrous material" may be felt.

[0035] The fourth method of differentiating the properties is to use a plurality of ink penetrating materials as "different materials" from one another. One example of the embodiment of using different materials is to use the above-mentioned synthetic resin porous body as one ink penetrating material and the above-mentioned fibrous material as another ink penetrating material. For example, the above-mentioned low moisture retention sponge (e.g., urethane sponge) may be used as the ink-adhering penetrating material 4A, and the above-mentioned high moisture retention and high water absorption fibrous material (e.g., felt) may be used as the ink-reducing penetrating material 4B. Also, the above-mentioned low moisture retention type fibrous material may be used as the ink-adhering penetrating material 4A, and in that case, the above-mentioned high moisture retention and high water absorption sponge may be used as the ink-reducing penetrating material 4B.

[0036] As described above, by appropriately selecting the same or different materials with different properties, the ink-adhering penetrating material 4A can reliably adhere the pigment ink to the thread 3, while the ink-reducing penetrating material 4B can remove a portion of the pigment ink that has adhered to the thread 3. This allows the ink-reducing penetrating material 4B to appropriately reduce the amount of pigment ink that has adhered to the thread 3. Some of the above examples of penetrating material selection utilize "differences in hydrophilicity," which is brought about, for example, by the presence or absence of a hydrophilic group in the resin material. A material with relatively high hydrophilicity may be used as the ink-reducing penetrating material 4B. Some of the above examples of penetrating material selection utilize "differences in moisture retention," "differences in water retention performance," or "differences in water absorption," and these differences in properties are brought about by differences in the size of microbubbles and the strength of their capillary phenomenon, differences in the strength of self-absorption, and the presence or absence of an open-cell structure. By applying a material with relatively high moisture retention, water retention, or water absorption to the ink-reducing penetrating material 4B, a portion of the pigment ink that has adhered to the thread 3 may be removed by the ink-reducing penetrating material 4B.

[0037] In the embodiment, as shown in FIG. 3, the ink reducing means 4B is disposed closer to the yarn reeling outlet 11D than the ink-adhering penetrant material 4A. This allows clear lines to be drawn when using pigment ink. In other words, when the ink-adhering penetrant material 4A is impregnated with pigment ink, the amount of ink that adheres to the yarn 3 tends to be large, and a unique problem has been found that it is difficult to control this by adjusting the material or structure of the ink-adhering penetrant material 4A. In the embodiment, the ink-adhering penetrant material 4A can reduce the amount of ink that adheres too much. The excess pigment ink on the yarn 3 is filtered out by the ink reducing means 4B, resulting in optimal adhesion. This allows clear lines to be drawn.

[0038] In the embodiment, the length dimension as viewed in the drawing direction of the thread 3 passing through the ink chamber is also devised. As an example, the length dimension L1 of the ink-adhering penetrant material 4A is made larger than the length dimension L2 of the ink-reducing penetrant material 4B (L1>L2). A relatively large ink-adhering penetrant material 4A can be implemented while ensuring the ink-reducing function. Since the ink-adhering penetrant material 4A can contain a sufficient amount of pigment ink, the frequency of ink replenishment can be reduced. As an example, L1 may be about 20 mm or more, and L2 may be about 5 mm or less, and the ratio between them may be adjusted arbitrarily. When the ink-adhering penetrant material 4A and the ink-reducing penetrant material 4B are viewed as forming a layer structure, the dimensions L1 and L2 may be referred to as "thickness dimensions L1 and L2".

[0039] The wire drawing tool main body 1 of the embodiment is also characterized by adopting an ultra-sealed structure that is resistant to drying. As one of the ultra-sealed structures, in the embodiment, the insertion hole 11G of the yarn reeling outlet 11D is devised. As an example, the yarn reeling outlet 11D has a tapered portion 11F (see FIG. 3) that tapers toward the inside of the case 11, and the insertion hole 11G extends through the tapered portion 11F to the inside. The diameter of the insertion hole 11G may be smaller than the diameter of the fastening needle 62 of the fastening tool 6. As a modified example, the diameter of the insertion hole 11G may be set to a diameter that fits with the fastening needle 62. The diameter that fits is approximately the same as the thickness of the fastening needle 62, and is set so that the fastening needle 62 can be received without creating an excessive gap (clearance). When the thread reeling outlet 11D receives the tip 61a of the handle 61 of the fastening tool 6, the fastening needle 62 can close the insertion hole 11G, thereby achieving airtightness.

[0040] As another example of this ultra-sealed structure, sealing means S1 to S3 are provided as shown in the cross-sectional view of Fig. 3. As one example, each of the sealing means S1 to S3 is a packing made of a rubber elastic member or an elastic synthetic resin member, and more specifically, may be a seal ring such as an O-ring. By providing these sealing means S1 to S3 in addition to the sealed structure in which the insertion hole 11G is blocked by the fastening needle 62, the sealing performance of the case 11 can be dramatically improved.

[0041] FIG. 4 is a diagram showing a modified example of the ink reducing means 4B. As a modified example, the ink reducing means 4B may be disposed closer to the spool 2 than the ink-adhering penetrating material 4A. This modified example also allows the ink reducing means 4B to reduce the amount of ink that has adhered to the thread 3. If too much ink adheres to the thread 3 during winding, too much pigment ink is likely to get into the spool 2. In the embodiment, the sealing means S1 to S3 are used to improve the sealing performance, but it is desirable to avoid the pigment ink being easily taken into the spool 2 and leaking out of the case 11. In this regard, in this modified example, the ink reducing means 4B can suppress such problems specific to pigment ink (adverse effects caused by the tendency of the pigment ink to adhere too much to the thread 3). A new line drawing tool 100 suitable for use with pigment ink is provided.

[0042] 5 is a diagram showing a modified example of the ink reducing means 4B. As a modified example, the ink reducing means 4B may be disposed on both the side of the yarn reeling outlet 11D and the side of the spool 2 as viewed from the ink-adhering penetrating material 4A. This has the advantage that the amount of ink adhering to the yarn 3 can be appropriately controlled in both the operations of pulling out and winding the yarn 3.

[0043] The thread reeling outlet 11D, the thread spool storage section 11A, and the ink chamber in the ink chamber section 11B may be arranged in series on the same straight line, but are not limited to this, and there are no limitations on their relative positional relationship. The route through which the thread 3 is pulled out is determined arbitrarily according to the internal structure of the case 11. The thread 3 can extend in a straight line between the thread spool 2 and the thread reeling outlet 11D, or can extend after passing through an arbitrary bend. An ink chamber may be provided at any position from the thread spool 2 to the thread reeling outlet 11D. Thus, the overall shape and internal structure of the case 11 may be modified arbitrarily.

[0044] The ink reducing means 4B may be provided in the same ink chamber as the ink-adhering penetrating material 4A, but is not limited to this. There is no limit to the specific location of the ink reducing means 4B inside the case 11. The ink reducing means 4B may be provided at any position from the spool 2 to the ink chamber, or from the ink chamber to the thread reeling outlet 11D, and an installation space for this purpose may be provided in the case 11.

[0045] In the above embodiment, the "various inks" used as the ink for drawing lines may be any one of India ink and pigment ink, or may be a mixture of two or more kinds of inks. The various inks in the embodiment may be, for example, a mixture of India ink and pigment ink in a predetermined ratio, or a mixture of a plurality of kinds of pigment ink in a predetermined ratio. The predetermined ratio of the mixture may be equal, or may contain any main component in half or more. Alternatively, the various inks in the embodiment may be India ink or pigment ink or a mixture of these, further mixed with other additives, additives, thinners, etc. The various inks may be colored liquids such as other water-based paints. Although the line drawing tool 100 in the embodiment has an improved structure suitable for using pigment ink from the various inks, it is also possible to use India ink or various water-based paints as the various inks. It has an excellent feature that the same hardware can be used for both pigment ink and India ink. The case 11 may be constructed so that the ink adhesion penetrating material 4A and the ink reducing means 4B are each detachable and replaceable from the ink chamber.

[0046] There is no limitation on the material of the thread 3. The thread 3 may be, for example, a nylon twisted thread or a nylon and aramid fiber twisted thread. As another example, the thread 3 may be a polyester twisted thread, a nylon braided thread with a nylon single thread in a core, or a silk thread.

[0047] In the embodiment, as shown in FIG. 3 as an example, a plurality of ink penetrant materials (ink-adhering penetrant material 4A and ink-reducing penetrant material 4B) having different properties are arranged in the same ink chamber, and the amount of ink adhering to the thread 3 is appropriately adjusted according to the difference in the properties of the ink penetrant materials. However, the present disclosure is not limited to this structure. As a modified example, a plurality of ink penetrant materials may be arranged at a distance inside the case 11, and in that case, a partition or the like may be provided between the two penetrant materials to partition them into separate chambers. In this case, the plurality of ink penetrant materials may be made of the same type of material, have the same material and structure as each other.

[0048] In the present disclosure, the "arrangement" of a plurality of ink penetrating materials may be a configuration in which a plurality of individual components having an ink penetrating function are arranged side by side, or may be a "configuration in which a plurality of adjacently arranged ink penetrating materials are integrated, that is, provided as one part." That is, as one of the variations, a layered integrated structure in which different ink penetrating materials are stacked and integrated may be used. The layered integrated structure may be a structure in which different ink penetrating materials are integrally molded in layers in a manufacturing stage such as a foaming process, or a layered integrated structure in which one ink penetrating material is bonded to another ink penetrating material by bonding or the like. Specifically, for example, in the example of FIG. 3, the ink reducing penetrant 4B, which is another sponge layer or fiber material layer, may be laminated on the surface (the surface on the thread reeling outlet 11D side) of the ink-attaching penetrating material 4A, which is a sponge. A layered sponge structure, a structure in which a nylon nonwoven fabric is bonded to the sponge surface, and the like are commercially available as kitchen sponges, and a manufacturing method similar to these may be used to manufacture the above variations. As another variation, a single ink penetrating material of the same material may be formed with a plurality of parts with different properties. For example, a sponge made of the same resin material as a whole may have multiple parts or layers with different porosities. In a sponge made of the same material, a first part may have a first property such as a predetermined porosity, and a second part adjacent to the first part may have a second property different from the first property. In such a case, the first part of the sponge corresponds to the first ink penetrating material, and the second part corresponds to the second ink penetrating material. In the above modification, the description is given using the expression that multiple ink penetrating materials form layers, but a layer of another ink penetrating material having intermediate properties between the ink-adhering penetrating material 4A and the ink-reducing penetrating material 4B in FIG. 3 may be inserted (in this case, a stepped three-layer structure is formed). Similarly, any number of layers such as four or five layers may be used, and multiple layers may be provided between the ink-adhering penetrating material 4A and the ink-reducing penetrating material 4B to provide a gradational property distribution as a whole.

[0049] As described above, a wide variety of modified configurations are possible for the ink adhesion penetrant material 4A and the ink reduction means 4B (ink reduction penetrant material 4B). Regardless of the arrangement, materials, etc., a certain effect can be obtained by reducing excess ink on the thread 3 with the ink reduction means 4B, so a wide variety of variations are possible.

[0050] The relationship between the dimensions L1 and L2 is not limited to L1>L2 as illustrated in the embodiment. <L2でもよい。

[0051] We will explain the relationship between modern construction methods and ink. Due to recent changes in construction methods, an increasing number of craftsmen are only drawing sub-inks (work lines) instead of main inks. The materials onto which sub-inks are drawn on-site are also diversifying, including gypsum boards, concrete, and steel frames. When drawing lines with ink on such a diverse range of materials, problems such as "repellency," "slow drying," "bleeding," and "low visibility" can easily occur.

[0052] In the present disclosure, the pigment ink is not limited in terms of ingredients, etc., but as a countermeasure to the above problem, in the embodiment, the pigment ink may be selected from the following viewpoints. Conventional ink may repel when the surface of the mating material to be inked is smooth and has low friction, and has the disadvantage that it cannot be easily erased by wiping with water. In addition, it has the disadvantage that it cannot be clearly colored depending on the color of the mating material. Therefore, as the pigment ink according to the embodiment, a pigment ink having a property that does not repel and can draw clear lines even when the surface of the mating material to be inked is smooth and has low friction may be selected. A pigment ink that can easily erase unnecessary lines or lines to be corrected by wiping with water may be selected. A pigment ink that does not bleed easily even on a concrete surface where ink bleeds, and dries quickly even when applied to a metal member such as LGS (lightweight steel frame) where ink dries slowly may be selected. A pigment ink having an ink color with high visibility that clearly develops color may be selected according to the color of the mating material. The combination of the mating material and the ink color may be as follows. If the mating material is panel coat (plywood with a urethane coating on the surface), the pigment ink color may be violet. If the mating material is plasterboard, it may be white. If the mating material is a floor soundproofing mat, it may be pink. If the mating material is LGS (lightweight steel frame), it may be orange. If the mating material is steel frame, it may be yellow. If the mating material is concrete, it may be green. In this manner, ink of any color may be put into the ink chamber of the line drawing tool main body 1.

[0053] To summarize the features of the hardware structure of the line drawing tool 100 in the embodiment, one feature is the dryness countermeasure. The line drawing tool 100 can be used for both the main ink and the sub ink, but if the line drawing tool 100 is used for the sub ink, it is likely to be used infrequently. If it is used infrequently, the ink inside is likely to dry out due to the interval between uses. In this regard, in the embodiment, the gaps are sealed with rubber packing or the like as much as possible, providing an ultra-sealed hardware that is resistant to dryness. Specifically, by providing sealing means S1 to S3 as shown in FIG. 3, both axial ends of the thread spool 2 are sealed with sealing rings (specifically, O-rings). In particular, the sealing means S1 can seal even a small gap associated with the opening and closing structure of the thread spool cover 12. Furthermore, by configuring the fixing needle 62 to block the insertion hole 11G, the thread reeling outlet 11D can be reliably sealed. This suppresses dryness, so that the ink can be prevented from drying out even when there is a long interval between uses.

[0054] Another feature of the embodiment is a structure in which ink penetrating materials with different properties are placed in the ink chamber, and the amount of ink is adjusted by utilizing the difference in these properties. If the pigment ink separates inside the ink penetrating material (sponge, etc.), it tends to adhere poorly to the thread 3. In this regard, multiple ink penetrating materials (sponge, etc.) with different properties such as water retention are arranged in series in the direction in which the thread moves forward and backward (pulling / winding direction). This makes it possible to apply an appropriate amount of pigment ink to the thread 3, preventing the pigment ink from separating and forming lumps (not adhering too much). [Explanation of symbols]
