  However, in the case of black ink, since a colored liquid is used as a marking material, it is difficult to fall off when it adheres to the operator's hand or clothes, and it is difficult to erase and correct it once it has been drawn on the counterpart material. Moreover, it is necessary to tightly seal the opening and closing parts and joints of the body with packing so that the filled coloring liquid does not leak to the outside of the ink cartridge, and the coloring liquid may still leak and stain the surroundings. It was.

  On the other hand, in the case of a marking device using powder as a marking material, part of the powder is scattered and floats in the air in the process of pulling out the thread with the powder attached from the yarn outlet of the body of the marking device. “Powder” occurs, and the problem is that powder is wasted. In addition, when “powder” occurs, there is a concern about adverse health effects caused by the operator's inhalation. Also, when the surface of the mating material is wet, drawing the wire on such a surface will wet the yarn, and the powder adhering to it will also become wet and become a granular lump, or powder on the yarn. Since it is difficult for the body to adhere uniformly, especially because the powder is difficult to adhere to the yarn in the initial stage of use, it is difficult to draw a good wire, and the powder adheres only to the surface of the yarn. Line drawing could not be performed continuously several times by thread drawing.

  In addition, since it is necessary to fill the body with powder, this powder intervenes between the parts inside the body to give a load and become a resistance and not work or to secure the required filling amount However, it was necessary to enlarge the body to some extent, and it was difficult to fill the proper amount. In addition, since the powder is filled around the bobbin, for example during maintenance, the bobbin that has been removed from the body cannot be set again unless all the internal powder is taken out.

  First, as shown in FIGS. 1 and 2, a marking device according to the present invention includes a body 1, a bobbin 2 that is rotatably housed in the body 1, and a bobbin 2 wound around the bobbin 2 to the outside of the case 1. A thread 3 to be pulled out is provided. The thread 3 corresponds to the thread-like body described in claim 1, and a fastener 5 is connected to the leading end led out of the body 1.

  The body 1 includes a grip portion 1A having a substantially cylindrical appearance and a flat circular bobbin storage portion 1B. As shown in FIG. 2, a filling chamber 1C that can be opened and closed by a lid 11 attached to the grip 1A via a hinge 11a is formed inside the grip 1A. It can be opened and closed by a ring-shaped holder 12 that is locked.

  The bobbin 2 includes a bobbin 21 that winds the yarn 3 around the outer periphery, and a winding handle 22 that is integrally and concentrically provided on one axial side of the bobbin 21, and the outer surface of the winding handle 22. A plurality of finger-hanging recesses 22a for rotating with fingers are formed. Inside the bobbin 21, a winding spring (not shown) is stored by rotating the bobbin 2 in the pulling-out direction of the yarn 3, and urges the bobbin 2 in the winding direction, and the winding spring is attached to the bobbin 21. A spring charge mechanism (not shown) capable of arbitrarily adjusting the force is provided.

  The yarn 3 wound around the bobbin 21 of the bobbin 2 passes through the threading groove 13a formed in the partitioning wall 13 on the bobbin storage unit 1B side in the filling chamber 1C, and in the filling chamber 1C and on the side opposite to the bobbin storage unit 1B. It is led out of the body 1 from the thread outlet 1D at the tip of the grip portion 1A through the threading groove 14a formed in the partition wall 14. The threading grooves 13a and 14a are provided with scrapers 15 and 16 made of sponge, cotton or rubber plate, respectively.

  A dome-shaped diaphragm 43 made of a rubber material is closely fitted in a circular hole formed in the center portion of the lid 11 in the grip portion 1A of the body 1, and an inner surface of the diaphragm 43 is made of a synthetic resin material or the like. A pressing member 17 is attached. Then, with the lid 11 closed, the pressing member 17 is pushed down by pressing the diaphragm 43 with a finger or the like, and the thread 3 passing through the filling chamber 1C is displaced to the bottom side of the filling chamber 1C. Can be done. If the pressing of the diaphragm 43 by a finger or the like is released, the pressing member 17 returns by the restoring force of the diaphragm 43.

  As shown in FIG. 3, the fastening device 5 includes a handle 51 having a needle protrusion 51a and a hollow portion 51b extending from the needle protrusion 51a, and is housed in the hollow portion 51b so as to be movable in the longitudinal direction.

The tip of the thread 3 is locked to a thread retaining part 51c formed on the handle 51 through the needle protrusion 51a.

  In this fastening device 5, the core member 52 is normally retracted to the moving rear end position in the hollow portion 51 b of the handle 51 by the urging force of the coil spring 54. 3 is retained in the hollow portion 51b from the needle projecting port 51a. In use, the core member 52 is pushed against the urging force of the coil spring 54 with one finger, and the point shown in FIG. As indicated by the chain line, the needle 53 can be pushed out from the needle protrusion 51a and can be inserted into the wood W to be drawn.

  The marking device having the above-described form fills the filling chamber 1C formed in the grip portion 1A of the body 1 with the foam-like marking material M, and fills the yarn 3 drawn from the bobbin 21 of the bobbin 2 to the outside of the body 1. The foamed marking material M in the chamber 1C is attached, and the yarn 3 is used for drawing.

  Foam marking material M is suitable for marking materials selected from white, black, vermilion, and other suitable colors of water-based ink, oil-based ink, ink, pigment, water-based paint, oil-based paint, dye, and colored powder. By mixing a foaming agent and adding a liquid or fluid such as water as necessary, it becomes a fluid material such as liquid or paste, and by mixing it with countless fine bubbles, it becomes a whipped cream shape. It is a thing. Here, a case where colored powder is used as the marking material will be described. Further, as the foaming agent, a surfactant (for example, a soap or a liquid synthetic detergent), a protein such as egg white, saponin, or the like can be considered, but here, it is assumed that a surfactant is used.

  When drawing a wood or the like using the marking device according to the illustrated embodiment, first, the lid 11 of the grip portion 1A of the body 1 is opened, and an aerosol-type foaming container or a trigger-type foaming pump is provided. The foamed marking material M is filled from the outside into the filling chamber 1C by the container.

  Then, the needle 53 of the fastener 5 is pushed out of the handle 51 by the core member 52 and is inserted into one of the starting points of the drawing on the surface of the drawing target wood W shown in FIG. When the body 1 is moved in the drawing direction after wearing, the thread 3 wound around the bobbin 21 is pulled out by the moving distance of the body 1 while the thread winding 2 in the body 1 rotates. . In addition, a winding spring (not shown) built in the bobbin 2 is thereby wound and stored.

  Since the yarn 3 passes through the filling chamber 1C of the body 1 in the process of being pulled out from the spool 2, the foamed marking material M in the filling chamber 1C comes into contact with and adheres thereto. At this time, the foam marking material M has better adhesion as compared with the case of using a marking material made only of powder such as chalk powder, and also contains a surfactant, so that the moisture is between the fibers of the yarn 3. So that it adheres well to the thread 3.

  Further, since the thread 3 that has passed through the filling chamber 1C is scraped off the excess foam-like marking material M by the scraper 16 made of sponge, cotton, rubber plate or the like provided in the threading groove 14a, the thread 3 is The foamed marking material M is pulled out in a uniformly attached state.

  As described above, the foam marking material M contains a colored powder, but is mixed with a surfactant or the like to form a liquid or paste to produce a whipped cream. Therefore, when the powder is pulled out from the yarn outlet 1D of the body 1, there is no occurrence of “powder” in which the colored powder scatters and floats. Moreover, since it contains countless fine bubbles, the consumption of colored powder and the like is reduced.

  Further, the foamed marking material M in the filling chamber 1C has a good stagnation because it is in the form of a whipped cream, and therefore leaks from the filling chamber 1C to the outside of the body 1 as in the case where a colored liquid is used as the marking material. Less likely

  Further, the foam marking material M has a fluid bearing effect due to innumerable bubbles and a surfactant as a foaming agent. Therefore, the load due to friction of the yarn 3 is extremely small. Is pulled out smoothly, and wear of the sliding portion with the yarn 3 is also effectively suppressed.

  Further, even when the amount of the foam marking material M in the filling chamber 1C is reduced, the pressing member is formed by pressing and denting the dome-shaped diaphragm 43 provided on the lid 11 in the grip portion 1A of the body 1 with fingers. If 17 is pushed down, the thread 3 passing through the filling chamber 1C is forcibly displaced toward the bottom side of the filling chamber 1C, so that the foam marking material M can be reliably attached.

  When the body 1 is moved to the other starting point of the line drawing, the thread 3 is held between the fixing member 5 by holding the thread 3 against the wood W to be drawn at the tip of the thread exit 1D of the body 1. The foam marking material M adhering to the thread 3 is struck by flicking the thread 3 toward the surface of the wood W with a finger or the like, so that a line by the foam marking material M is drawn. . And since the foam-like marking material M has adhered uniformly to the thread | yarn 3, a uniform thickness line can be obtained. In addition, as described above, since the foam marking material M contains a surfactant, moisture soaks into the fibers of the yarn 3 and adheres to the yarn 3 in a well-adhered state. Multiple line drawing can be continuously performed by the thread drawing.

  In addition, the line drawn on the surface of the wood W to be drawn is mostly made of colored powder when the foam disappears when it is dried, and can be easily wiped off after the drawing work. After that, you can easily erase and start over. Moreover, even if the foam marking material M is excessively attached to the hands or clothes of the operator, the components of the foam marking material M are colored powder and a surfactant, so that they can be easily washed off. it can.

  After the drawing work is completed, when the body 1 is moved toward the drawing starting point where the tip of the yarn 3 is fastened by the fastening device 5, the bobbin 2 in the body 1 is stored in the process of drawing the yarn 3. The yarn 3 is automatically wound around the bobbin 21 by rotating in the winding direction by the loosening action of the winding spring. Finally, when the fastening tool 5 is pulled out from the wood W, the thread 3 is further wound, and the fastening tool 5 is locked to the thread outlet 1D of the body 1 in a semi-contained state.

  In the winding process as described above, the foam marking material M adheres to the yarn 3 that passes through the filling chamber 1C toward the bobbin 2, and this yarn 3 is a partition wall on the bobbin storage portion 1B side. The foamed marking material M is scooped off by a scraper 15 made of sponge, cotton, rubber plate or the like provided in a threading groove 13a formed in 13, and then wound around the bobbin 2. Moreover, since the load by the foam marking material M is remarkably small as mentioned above, the thread | yarn 3 is wound up smoothly.

  The bobbin 2 (bobbin 21) may be structured to wind the yarn 3 by a manual handle or rotated by an electric motor or the like.

  FIG. 4 is an exploded perspective view showing the internal mechanism of the marking device according to the second embodiment of the present invention, and FIGS. 5 and 6 are cross-sectional views of the main part showing an example of the foaming device in the second embodiment. That is, the marking device according to this embodiment has the foaming device 4 built in the body 1 and the other parts are basically configured in the same manner as in FIGS. 1 and 2 described above.

  As shown in FIG. 5 or 6, the foaming device 4 includes a sponge 41 that is a porous elastic body disposed in the filling chamber 1 </ b> C in the body 1, and the sponge 41 that is attached to the lid 11 in the body 1. It consists of the pushing member 42 which can press. Specifically, the pushing member 42 is attached to the inner surface of a dome-shaped diaphragm 43 made of a rubber material tightly fitted in a circular hole opened in the center of the lid 11, and the diaphragm 11 is closed with the lid 11 closed. By pushing 43 with a finger or the like to be recessed, the pushing member 42 is displaced downward and the sponge 41 can be compressed.

  FIG. 5 shows an example in which the sponge 41 is arranged on the entire bottom of the filling chamber 1C, and FIG. 6 shows an example in which a plurality of sponges 41 are arranged on a part of the bottom in the filling chamber 1C. It is.

  Similarly to the above-described marking apparatus, the filling chamber 1C formed in the grip portion 1A of the body 1 is also provided with an aerosol-type foam dispensing container or a trigger-type foaming pump-equipped container. The foamed marking material M is enclosed and filled, and the foamed marking material M in the filling chamber 1C is attached to the yarn 3 drawn out from the bobbin 21 of the bobbin 2 to the outside of the body 1, and the yarn 3 is used for drawing.

  The bubbles of the foam marking material M can be made into a stable foam that does not disappear over a long period of time by adjusting the type and blending ratio of the surfactant and protein as the foaming agent. Depending on the blending components, the foam marking material M once sealed in the filling chamber 1C disappears with time due to evaporation of moisture and returns to a liquid or paste fluid material. And according to the marking apparatus of the 2nd form, such a fluid material is made to foam again in the filling chamber 1C, and the foam-like marking material M can be easily remanufactured.

  Specifically, the above-described fluid material from which bubbles have disappeared is absorbed by the sponge 41 in the filling chamber 1C. Therefore, when the pushing member 42 is displaced downward by pushing the diaphragm 43 provided on the lid 11 of the filling chamber 1C with fingers or the like, the pushing member 42 compresses the sponge 41, so that the fluid material is pushed out. At this time, the remaining air in the sponge 41 is also pushed out and mixed together to generate countless bubbles. When the pressing of the diaphragm 43 by a finger or the like is released, the pushing member 42 is returned to the original position by the restoring force of the diaphragm 43, and the compressed sponge 41 swells to the original shape and flows again in the process. Absorbs some of the material. Therefore, the foam marking material M can be remanufactured in the filling chamber 1 </ b> C by repeatedly performing the above-described pressing operation with fingers or the like an appropriate number of times.

  In addition, although the 2nd form was set as the structure provided with the foaming apparatus 4 in the body 1, it replaces with such a foaming apparatus 4, for example, pushes the diaphragm 43 provided in the lid | cover 11 with fingers etc., and dents it. In this way, air is sent to the nozzle by the piston operating via the pushing member 42, and the mixed powder of the colored powder and the surfactant sucked up in the process is entrained to supply the foam marking material M into the filling chamber 1C. It can also comprise so that the foaming pump to perform may be provided.

  In the above description, the foam marking material M is sealed and filled into the filling chamber 1C by an aerosol foam discharge container or a trigger foaming pump-equipped container. A flowable material made into a liquid or paste form by mixing a marking material such as colored powder and a surfactant is injected into the filling chamber 1C by opening the lid 11 of the grip portion 1A of the body 1, and foaming is performed. It is also possible to generate and use in the filling chamber 1C by causing the device 4 to foam.

  The foaming device 4 is not limited to the one that repeatedly presses the porous elastic body such as the sponge as described above, and the liquid or paste-like material is vibrated and agitated by electric power or other power. Something to make you think is also possible.

  In the above description, the fastening device 5 connected to the tip of the thread 3 has the needle 53 for wood, but it is also possible to use a fastening device with a hook or a magnet.
