The hygroscopic material consists of a sponge-like ink drum impregnated with ink, a rubber ink guide that surrounds the outer periphery of the ink drum and allows ink ink to leak to the outer periphery, and a mesh-shaped protective cover that surrounds the outer periphery Has been.

  In this inking operation, the first stop pin (karuko) attached to the tip of the thread is attached to the starting point of the other material, and then the case is moved to pull the thread from the spool. Then, it is stretched along the surface to be ink-printed of the counterpart material. The ink impregnated in the ink drum of the hygroscopic material in the rotary drum oozes through the rubber ink guide and the mesh-shaped protective cover and adheres to and penetrates into the yarn. Therefore, a straight ink line can be transferred by flicking the tensioned thread toward the ink marking target surface with a finger. In addition, when the amount of ink impregnation in the ink drum is reduced by repeating the inking operation several times, the small hole opened in the side plate of the case through the small hole opened in the side plate of the rotating drum, Ink can be supplied to the ink drum.

  However, in the case of the above-mentioned conventional ink brush, if the amount of ink supplied to the ink drum is too large, the excess amount of the ink splashes into the case as the rotating drum rotates, causing leakage to the outside of the case.

  As shown in FIG. 6, the ink absorbing body 6 provided on the spool 2 is made of cotton, felt, sponge, or the like, and is filled in a space formed between the inner peripheral cylindrical portion 21d of the bobbin 21 and the peripheral wall 21e. ing. As shown in FIGS. 3 and 6, this space is divided into four equal parts in the circumferential direction by ribs 21 h, and the first window portion 21 f opened on the side wall 21 b of the bobbin 21 and the peripheral wall of the bobbin 21, respectively. 21e has a second window portion 21g opened between the ribs 21h. For this reason, the ink absorption body 6 is exposed to the interior of the case 1 through the first window portion 21f and contacts a part of the thread 3 wound around the peripheral wall 21e through the second window portion 21g. Has been.

  Further, as shown in FIG. 6, the yarn 3 wound around the bobbin 2 (bobbin 21) is in good contact with the ink absorber 6 due to the tension between both ends of each second window portion 21g. Since the tightening of the ink 3 by the thread 3 is regulated by the peripheral wall 21e and the rib 21h, the ink absorber 6 is not compressed as in the case where the thread 3 is directly wound around the ink absorber 6. Therefore, the excess ink is absorbed well.

  As shown in FIG. 4, the inside of the first cover 11 on one side of the grip portion 1A of the case 1 is a drawer / rewind path 1C. The drawer / rewind path 1C includes a sponge, The second ink absorption body 7 made of cotton or felt is filled, and the thread 3 led out from the bobbin 2 (bobbin 21) comes into contact with the second ink absorption body 7.

By fitting, the drawer / rewind path 1C is sealed.

  The ink supply means 5 for the thread 3 is provided in the inner space 1D of the second cover 12 on the other side of the grip portion 1A of the case 1. The second cover 12 is opened and closed around a hinge portion 12a formed at the end opposite to the bobbin storage portion 1B.

  Specifically, as shown in FIGS. 3 and 4, the ink supply means 5 is provided in the cassette loading portion 17 formed in the partition wall 1 </ b> E between the inner space 1 </ b> D of the second cover 12 and the drawing / rewinding path 1 </ b> C. A synthetic resin cassette bottle 51 that is detachably loaded, and a discharge made of a rubber-like elastic material that is attached to the support projection 17a of the cassette loading portion 17 and whose discharge port 52a faces the outer peripheral side of the bobbin 21 in the bobbin 2. Nozzle 52. The cassette bottle 51 is easily depressed by pressurization with fingers and has a required elastic restoring force. When the cassette bottle 51 is loaded in the cassette loading unit 17, the cylindrical extraction port 51 a is connected to the discharge nozzle 52. It is designed to be tightly fitted.

  On the inner surface of the second cover 12, a pressing protrusion 12b capable of pressing the discharge port 52a of the discharge nozzle 52 is formed. In FIG. 4, the discharge port 52a is shown in an open state. However, when the second cover 12 is closed as shown in FIG. 4, the discharge port 52a is actually crushed by the pressing protrusion 12b. This prevents inadvertent outflow of the ink in the cassette bottle 51.

  A thread presser 18 is formed at the tip of the grip portion 1A of the case 1, and the inner periphery thereof is a thread delivery port 1F. The yarn delivery port 1F is passed through the yarn 3 passing through the drawing / rewinding path 1C, and the yarn presser 18 is for pressing the yarn 3 drawn out from the yarn delivery port 1F against the counterpart material.

  Note that an unillustrated karuko having a needle for fixing the thread 3 to the mating material is connected to the tip of the thread 3 pulled out from the thread unwinding port 1F. It is held in a holding recess 1G formed on the outer side.

  The ink brush according to the first embodiment has the above-described configuration, and when performing ink marking (drawing) using this ink brush, first, the yarn wound around the bobbin 21 of the spool 2 as necessary. 3. Apply an appropriate amount of ink to 3 and keep it attached. This ink supply can be performed by opening the second cover 12 in the grip 1A of the case 1 and pushing the cassette bottle 51 in the ink supply means 5 with fingers. In this case, if the case 1 is arranged so that the bobbin winding portion 1B faces downward, the ink discharged from the cassette bottle 51 through the discharge nozzle 52 is surely applied to the yarn 3 wound around the bobbin 21. Can be dripped.

  The supplied ink is spread over the entire thread 3 wound around the bobbin 21 by capillary action. Further, the ink ink splashed or flown down from the yarn 3 into the spool housing part 1B in the case 1 is sucked into the ink absorbing body 6 exposed from the first window portion 21f opened on the side wall 21b of the bobbin 21, and is thus formed on the inner peripheral side. The surplus ink that has flowed into is absorbed by the ink absorber 6 through the second window 21g of the bobbin 21. Since the pincushion storage part 1B is sealed with O-rings 16, 27, 47, etc., the ink ink does not easily leak from the pincushion storage part 1B to the outside of the case 1, but in addition, the ink ink absorber Since excess ink is absorbed by 6, it is possible to effectively prevent the ink from leaking outside the case 1.

  In the inking operation, first, the unillustrated karuko attached to the tip of the thread 3 is fixed to one starting point of inking on the surface of the counterpart material, and then the case 1 is inked. When moving toward the other starting point, the yarn 3 wound around the bobbin 21 is fed out by the moving distance of the case 1 with the rotation of the bobbin 2.

  At this time, the ink absorbing body 6 provided in the spool 2 recirculates the ink absorbed once to the thread 3 wound around the bobbin 21 by centrifugal force due to rotation when the thread 3 is pulled out or capillary action. Has the function of evenly penetrating. Further, since the yarn 3 is slidably contacted with the second ink absorbing body 7 in the process of being drawn out from the yarn feeding port 1F through the drawing / rewinding path 1C, the unevenness of the ink adhering to the yarn 3 is leveled and uniform. The ink is attached to the ink.

  When the case 1 is moved to the other starting point of the ink stroke, the yarn 3 is held against the mating material by the tip of the thread presser 18 of the case 1 so that the yarn 3 is stretched between the yarns. By striking 3 with a finger toward the surface of the mating member, a straight black line can be transferred. At this time, the ink 3 is uniformly adhered to the thread 3 without being excessive or insufficient, so that a clear ink line can be obtained without being thicker than necessary or becoming a thin and uneven line.

  After completion of the inking operation, if the karuko is pulled out from the mating material, the bobbin 2 is rotated in the winding direction by the loosening action of the spiral spring 23 stored in the unwinding process of the yam 3, so that the thread 3 is It is automatically wound around the bobbin 21 until the spar is locked in the holding recess 1G of the case 1 in a semi-stored state.

  Next, FIG. 7 is a side view showing a second embodiment of the ink bud according to the present invention, FIG. 8 is another side view thereof, and FIG. 9 is a cross section taken along the line IX-O-IX ′ in FIG. FIG. 10 is a cross-sectional view taken along line XX ′ in FIG. 9, FIG. 11 is a cross-sectional view showing the main part of FIG. 9, and FIG. It is explanatory drawing which shows.

  The ink brush according to the second embodiment is also provided with a case 1, a bobbin 2 that is rotatably provided in the case 1, and a curl 8 that is wound around the bobbin 2 so as to be pulled out of the case 1 and is applied to the tip. The connected yarn 3, the spring charge portion 4 provided in the spool 2, the ink supply means 5 for the yarn 3, the ink absorber 6 accommodated in the spool 2, and the drawer / winding in the case 1 And a second ink absorbing body 7 provided in the return path 1C.

  As shown in FIGS. 7, 8 and 9, the case 1 has a bobbin storage portion 1 </ b> B, a head 1 </ b> H, a thread guide portion 1 </ b> I, and a holder 1 </ b> J, and an index finger is inserted into the holder 1 </ b> J. The shape is such that you can hold it firmly with one hand as if you were holding a handgun.

  The bobbin storage unit 1B, the bobbin 2 and the spring charge unit 4 are basically configured in the same manner as in the first embodiment described above.

  Therefore, also in the second embodiment, the ink spool 6 is built in the spool 2, and the ink absorber 6 is made of cotton, felt, sponge, or the like, and as shown in FIG. A plurality of spaces formed by ribs 21h are filled between the peripheral cylinder portion 21d and the peripheral wall 21e. As shown in FIG. 10, the first window portion 21 f is formed on the side wall 21 b of the bobbin 21 so as to be equally spaced in the circumferential direction 4, and is located between the ribs 21 h on the peripheral wall 21 e of the bobbin 21. The 2nd window part 21g is established in the circumferential direction 4 equality. For this reason, the ink absorption body 6 is exposed to the interior of the case 1 through the first window portion 21f and is in contact with a part of the wound yarn 3 through the second window portion 21g. .

  Further, the yarn 3 wound around the peripheral wall 21e of the bobbin 2 (bobbin 21), as shown in FIG. 6 described above, is applied to the ink absorption body 6 by tension at the portion where the second window portion 21g is opened. Good contact. Since the tightening of the ink 3 by the thread 3 is regulated by the peripheral wall 21e and the rib 21h, the ink absorber 6 is not compressed as in the case where the thread 3 is directly wound around the ink absorber 6. Therefore, the excess ink is absorbed well.

  The inside of the thread guide portion 1I is a drawer / rewind path 1C. The drawer / rewind path 1C is filled with a second ink absorbing material 7 made of sponge, cotton, felt, or the like, and the spool 2 The thread 3 led out from the bobbin 21 is brought into contact with the second ink absorbing body 7. The cover 11 ′ that covers the side opening of the drawer / rewind path 1 </ b> C so as to be openable and closable is made of a rubber-like elastic material, and its outer edge is fitted into the edge of the side opening. The drawer / rewind path 1C is sealed.

  In this embodiment, as shown in FIGS. 9 and 10, the ink supply means 5 for the thread 3 includes an ink tank 53 defined in the head 1 </ b> H, and a pump device 54 provided in the ink tank 53. The pump device 54 includes a diaphragm 541, a pump housing 542, a suction valve 543, a discharge valve 544, a suction nozzle 545, and a discharge nozzle 546 attached thereto.

  Specifically, the diaphragm 541 is made of a rubber-like elastic material, is formed in a hemispherical dome shape, is easily recessed by pressing with a finger, and has a required elastic restoring force. The ink tank 53 can be filled with a predetermined amount of ink from an ink ink inlet that is opened and closed by a sealing member 548 integrally formed with the diaphragm 541. The suction nozzle 545 opens in the ink ink tank 53, and the discharge nozzle 546 passes through the ink ink tank 53 and opens in the bobbin storage unit 1 </ b> B facing the outer peripheral position of the bobbin 21 in the bobbin 2. The suction valve 543 is opened when the pump chamber 54a inside the diaphragm 541 becomes negative pressure, allows the ink flow from the suction nozzle 545 to the pump chamber 54a, and closes otherwise. . Further, the discharge valve 544 opens when the pump chamber 54a is pressurized, allows the ink flow from the pump chamber 54a toward the discharge nozzle 546, and closes otherwise.

  When inking (drawing) using the ink brush according to the second embodiment having the above-described configuration, an appropriate amount of ink is supplied and adhered to the yarn 3 wound on the bobbin 21 of the spool 2. This ink supply can be performed by pressing the dome-shaped diaphragm 541 in the pump device 54 with a finger a required number of times.

  That is, in the process in which the dome-shaped diaphragm 541 that has been depressed once by the finger is restored by its elasticity, the volume of the pump chamber 54a expands to become negative pressure, so that the discharge valve 544 closes and the suction is performed. The valve 543 is opened, and the ink in the ink tank 53 is sucked up from the suction nozzle 545 to the pump chamber 54a. Next, in the process in which the diaphragm 541 is pushed, the volume of the pump chamber 54a is reduced and pressurized, whereby the suction valve 543 is closed and the discharge valve 544 is opened, so that the ink in the pump chamber 54a is opened. Is supplied from the discharge nozzle 546 toward the yarn 3 wound around the bobbin 21 in the yarn winding storage unit 1B. The amount of ink supplied to the thread 3 can be arbitrarily adjusted by the number of times the diaphragm 541 is pressed. Then, the supplied ink is spread over the entire thread 3 wound around the bobbin 21 by capillary action.

  In order to reliably supply the ink ink to the yarn 3 wound around the bobbin 21 by the pump device 54, the case 1 is placed so that the opening end of the discharge nozzle 546 is positioned directly above the bobbin 21. It is desirable that the thread retainer 18 be directed downward. In this way, the ink ink discharged from the discharge nozzle 546 is dripped onto the yarn 3 wound in layers so as to pass directly under the discharge nozzle 546.

  Further, the ink ink splashed or flowed down from the yarn 3 wound around the bobbin 21 into the bobbin storage portion 1B in the case 1 was exposed from the first window portion 21f provided on the side wall of the bobbin 21 shown in FIG. Excess ink that has been sucked into the ink absorber 6 and has flowed to the inner peripheral side of the thread 3 is sucked into the ink absorber 6 through the second window portion 21g provided on the peripheral wall 21e of the bobbin 21. Since the pincushion storage 1B is sealed with O-rings 16, 27, 47, etc., the ink does not easily leak from the pincushion storage 1B to the outside of the case 1, but in addition, the ink absorber 6 As a result, excess ink is absorbed, so that leakage of ink to the outside of the case 1 can be effectively prevented.

  Then, in the inking operation, as shown in FIG. 12, the needle 8 a of the karuko 8 connected to the tip of the yarn 3 is fixed to one starting point of the inking on the surface of the counterpart material W. When the case 1 is moved toward the other starting point of the inking, the yarn 3 wound around the bobbin 21 is fed out by the moving distance of the case 1 with the rotation of the bobbin 2.

  At this time, the ink absorbing body 6 provided in the bobbin 2 returns the ink absorbed once to the thread 3 wound around the bobbin 21 by centrifugal force due to rotation when the thread 3 is pulled out or by capillary action. And has the function of evenly penetrating. Further, since the yarn 3 is in sliding contact with the second ink absorbing body 7 in the process of being drawn out through the pull-out / rewinding path 1C, unevenness of the ink ink adhering to the yarn 3 is leveled and the ink ink adheres uniformly. It becomes a state.

  When the case 1 is moved to the other starting point of the inking, as shown in FIG. 12, the thread 3 is held by the thread retainer 18 provided at the tip of the thread guide portion 1I in the case 1, thereby 3 is stretched between the sword 8 and the thread 3 is struck by a finger toward the surface of the counterpart material W, whereby a straight black line can be transferred. At this time, the ink 3 is uniformly adhered to the thread 3 without being excessive or insufficient, so that a clear ink line can be obtained without being thicker than necessary or becoming a thin and uneven line.

  After completion of the inking operation, if the karuko 8 is pulled out from the counterpart material W, the bobbin 2 rotates in the winding direction due to the loosening action of the spiral spring 23 stored in the unwinding process of the yarn 3, so that the yarn 3 Is automatically wound around the bobbin 21 until the karuko 8 is locked in the half-retracted state at the yarn feeding port 1F of the case 1.

  The present invention is not limited to the illustrated embodiment. For example, a thread wound around a bobbin in a case is drawn out of the case through a black ink chamber filled with a black ink penetrating member into which the black ink is infiltrated. It can be applied to other types of ink.
