Further, the bearing 12 provided in a U-shape at both left and right ends is provided with two left and right slider shafts 15 that are fixed through the upper and lower portions, respectively. A slider 13 that moves up and down along 15 is fitted, and is pushed upward by two coil springs 16 fitted into the two left and right slider shafts 15.

In addition, a plate-like front side wall portion 13A and a rear side wall portion 13B are provided in parallel at a predetermined height at the lower portion of the slider 13, and a serrated blade 14 is provided between the two in the middle. It is provided so as to be sandwiched between the slider shafts 15.

At this time, the pointed portion of the serrated blade 14 is disposed at a position recessed from the pointed portions of the front side wall portion 13A and the rear side wall portion 13B, and the distance between the front side wall portion 13A and the rear side wall portion 13B is as follows. The distance at which the finger does not easily touch the blade 14 through the gap (for example, 10 mm or less) is set.

Next, a method of using this embodiment will be described. FIG. 4 shows a state in which a cylindrical wrap is newly set. The cover portion 11 is lifted while rotating around the rotating shaft 11a, and the wrap 40 is lifted up to the front plate 21, the bottom plate 20, and the side plate of the main body portion 10. 23 and the back plate 22 are inserted into the wrap storage portion 10a.

Next, holding the lap end 41A of the lap 40, the lap is pulled out while sequentially passing over the cutout 27 and the flip-up plate 18 of the front plate 21, and the cover portion 11 is moved to the rotating shaft 11a. Rotate it around to return it to its original position.

FIG. 5 shows a state where the setting of the lap is completed. The side surface of the slider 13 is close to the front plate 21 and the front side wall portion 13A and the rear side wall portion 13B sandwich the lap drawn out and flip up. The plates 18 are opposed to each other so as to be substantially in contact therewith. Furthermore, in the lower part, the front side lap pressing part 17A and the rear side wrap pressing part 17B on the upper part of the lap receiver 17 provided on the front plate 21 of the main body part 10 are separated from the front side wall surface 13A of the slider 13 and the rear side by a predetermined distance. It faces the wall surface 13B.

Here, the slider 13 is brought close to the front plate 21, but when the front plate 21 is bent, the slider 13 is bent along the same and the slider shaft 15 is similarly bent along the same.

When the wrap is taken out and used, as shown in FIG. 6, the lap end 41A is pulled out, the necessary length is pulled out, and the slider 13 is moved downward along the front plate 21 while compressing the two left and right coil springs 16. Push into. At this time, the flip-up plate 18 is pushed by the rear side wall portion 13B of the lower end of the slider 13, rotates around the rotation shaft 18a against the torsion spring 26, and does not protrude from the front surface of the front plate 21, It is pushed into the rectangular hole 24 formed in the front plate 21 so as to be hidden.

Further, when the slider 13 is pushed in, the front lap pressing portion 17A and the rear wrap pressing portion 17B are respectively placed in the gap between the front side wall portion 13A and the cutter 14 at the lower part of the slider, and the gap between the rear side wall portion 13B and the cutter 14. The lap is fixed near the upper surfaces of the front lap pressing portion 17A and the rear lap pressing portion 17B, and the wrap is cut by the blade 14.

At this time, the heights of the front wrap pressing portion 17A and the rear wrap pressing portion 17B are at least higher than the heights of the front side wall portion 13A and the rear side wall portion 13B. The next portion of the lap intersects at least the distance between the front end of the pushed rear side wall portion 13B and the front end of the rear side wrap pressing portion 17B (usually the height of the rear side wall portion 13B). A slack having a length corresponding to twice the length of the slack is formed.

Next, when the hand is released from the slider 13 and released, as shown in FIG. 7, the slider 13 is returned to the original position by the two left and right coil springs 16 and the spring plate 18 is also restored to its original position by the force of the torsion spring 26. Returning to the position, the next lap end 41B corresponding to the slack is pushed out to the front. In the next pull-out, the wrap end 41B is held and the wrap is pulled out, and the above operations are repeated.

In this way, twice the height of the rear side wall portion 13B becomes the amount of slack in the next lap. Therefore, if the stroke amount of the slider is determined in consideration of the necessary amount of the next knob portion, the amount of pushing is reduced as much as possible. I can do it.

In the above-described embodiment, the slider shaft 13 is provided on the left and right sides. However, when the slider 13 is pushed in, a single linear guide can be used as long as the predetermined function is not impaired. .

Further, the cutting of the drawn lap includes the lap fixing action by the front lap pressing part 17A and the rear wrap pressing part 17B, the front side wall part 13A and the rear side wall part 13B below the slider 13, and the cutting action of the blade 14. However, in order to cut the wrap quickly and comfortably, the wrap fixing action should be further strengthened, and the slippage of the wrap during cutting should be reduced.

FIG. 8A shows an embodiment in which slippage of the lap is reduced when cutting the lap, and an anti-slip effect such as adhesiveness or roughness on the upper surface of the front lap pressing portion 17A and the rear wrap pressing portion 17B or in the vicinity thereof. The front side non-slip member 80A and the rear side non-slip member 80B are provided.

In this case, instead of the anti-slip member 80A and the anti-slip member 80B, the upper portions of the lap pressing member 17A and the rear lap pressing portion 17B may be respectively supported by a member having an anti-slip effect or an uneven surface. .

FIG. 8B shows another embodiment for reducing slippage of the wrap. The front sponge is formed in the two gaps between the front side wall 13A and the rear side wall 13B below the slider 13 and the blade 14 disposed between them. When 81A and the rear sponge 81B are arranged and the slider 13 is pushed in, the lap drawn by the interaction with the front lap pressing portion 17A and the rear wrap pressing portion 17B is held, and cutting with the blade 14 is easy. It is to make. In this case, it is also possible to use a member combined with a cushion member such as a spring instead of the sponge.

Here, the cylindrical wrap used in the above embodiment has a different core diameter and a different thickness and length of the wrap wound around the core. Is getting smaller.

Since the size of the part that normally stores the wrap does not change, even if the size of the storage part is determined assuming that the wrap diameter is large, the wrap with a small or small diameter is in the storage part during use. There may be a phenomenon in which the leading end of the drawn lap is pulled back by a so-called backlash phenomenon.

FIG. 9A is an embodiment showing a method for preventing the backlash phenomenon. A large wrap 91 having a large outer diameter is connected to the bottom plate 20 of the lap storage portion 10a by a lap pressing spring 93 attached to the cover portion 11. The large wrap 91 is pushed back and forth so that it does not move back and forth.

Next, the case where the outer diameter is reduced due to consumption of the wrap is the small wrap 92, and at this time, the wrap pressing spring 93 is deformed so that the small wrap 92 contacts the bottom plate 20 and the rear plate 22. It does not move back and forth while being pressed, so-called backlash is prevented, and the wrap end portion 91A is not pulled back.

FIG. 9B shows another embodiment for preventing backlash. A lap pressing plate 94 that can be rotated around a rotation shaft 92 a provided at the lower portion of the rear plate 22 has a large wrap 91 and the front plate 21 by the action of a pulling spring 95. It is pressed against the bottom plate 20 to prevent backlash of the large wrap 91.

Even when the wrap is consumed and the small wrap 92 has a small outer diameter, backlash is prevented by the wrap pressing plate 94 pulled by the pull spring 95.

9A and 9B described the method for preventing the movement of the lap itself as a method for preventing the backlash. However, if the lap diameter is changed, the lap can be kept at substantially the same position with respect to the lap storage portion. There is no dance and can prevent backlash.

FIG. 10A shows a tubular wrap sandwiched from both ends by a support member having a predetermined outer shape and mounted in the main body 10 to prevent the wrap from dancing. The tubular first wrap support member 100 and the tubular wrap The second wrap support member 103 is connected by a male screw 102 formed on the first wrap support member and a female screw 105 formed on the second wrap support member.

Furthermore, the outer periphery of each of the first wrap support member 100 and the second wrap support member 103 is provided with a first outer peripheral portion 101 and a second outer peripheral portion 104 having substantially the same outer diameter. Are formed with a first taper 101A and a second taper 104A that can be pressed while corresponding to the difference in inner diameter of the cylindrical wrap to be held.

FIG. 10B shows a wrap structure, which is formed of a cylindrical wrap core 110 and a wrap material 111 wound around the wrap core.

FIG. 10C shows a state in which the wrap is fixed to the wrap support member. From the state in which the first wrap support member 100 and the second wrap support member 103 are removed, each is passed through the wrap core 110 and the male screw 102. And the female screw 105 are combined and sandwiched. Thereby, the wrap material 111 is fixed to the wrap support member via the first taper 101A and the second taper 104A. At this time, the wrap material 111 is disposed substantially concentrically with respect to the wrap support member composed of the first wrap support member 100 and the second wrap support member 103.

FIG. 11 shows a state in which a wrap support member composed of a first wrap support member 100 and a second wrap support member 103 sandwiching a wrap material 111 is incorporated in the wrap storage portion 10a. The diameters 104 and 104 substantially match the distance between the front plate 20 and the rear plate 22 of the wrap storage portion 10a. Thereby, even if the size of the wrap to be used changes or the main body 10 is tilted, the drawn wrap end 111A is not sucked into the main body by backlash or the like.

Note that at least the first outer peripheral portion 101 and the second outer peripheral portion 104 of the wrap support member in order to prevent the wrap tip portion 111A after being cut off from being sucked into the main body portion by a dance such as backlash. The difference between the diameter of the wrap storage portion and the distance between the front plate 20 and the rear plate 22 is at least a length corresponding to the slack at the time of cutting the lap, that is, in the state where the rear cover 13B is pushed in, It is required to be smaller than twice the distance between the tip of the cover 13B and the tip of the rear wrap pressing portion 17B.

Next, the cover 11 is temporarily fixed so that the main body does not move during use when the main body is used on a table or the like so that the cover 11 does not open unexpectedly during carrying or handling. Means are shown.

In FIG. 12, a metal plate 122 containing a magnetic material such as iron is embedded in a part of the upper surface of the side plate 23. On the other hand, when the cover part 11 is closed, the magnet 121 is embedded at the position of the cover part 11 facing the metal plate 122. Thereby, when the cover part 11 is closed, it is temporarily attached to the main body part 10 by the action of the magnet.

In the above embodiment, instead of providing a magnet and metal, a concave portion and a convex portion or a convex portion and a concave portion can be provided in a part of the cover portion 11 and the side plate 23, respectively, and temporarily fixed by fitting each other. . Moreover, it is also possible to perform screwing using a bolt by providing a hole in the cover part 11 and providing a female screw hole in the upper part of the opposite side plate 23.

On the other hand, the bottom plate 20 of the main body 10 is provided with two suction cups 123 and two suction cups 124 (not shown on the back side of the paper), and can be temporarily fixed to a table or the like. It is also possible to use a suction member such as a magnet instead of the suction cup.

FIG. 13A is a plan view of an embodiment showing another shape of the slider 13. The slider 130 has a front side wall portion 130A corresponding to the front side wall portion 13A of the slider 13, a front side wall portion end portion 131A, and a rear side wall portion 13B. The rear side wall portion 130B and the rear side wall portion end portion 131B are equivalent to each other, the lower end surface of each wall portion is composed of 132A and 132B, and the lower end surface of each wall portion end portion is composed of 133A and 133B. The lower end of the slider 130 is divided into a lower end surface through which the wrap passes and an end lower end surface at the left and right sides thereof, and the position of the lower end surface is slightly depressed from the position of the end lower end surface, thereby pushing the flip-up plate 18. In this case, the inconvenience of direct contact between the wrap surface and the flip-up plate 18 is avoided.

Next, FIG. 13B is a bottom view of the slider 130. When the wrap is pulled out by bringing the side surface of the rear side wall portion 130B through which the lap passes to the inside of the nine side surfaces of the rear side wall portion end portion 131B of the left and right peripherals, It can be pulled out smoothly without causing friction due to the close contact of the equipment.
