Abstract

(57) [Abstract] [Problem] Hard machines for cutting steel materials etc. into circular shapes already exist and are operating in factories, etc., but especially cloth cutters for paper, cloth, synthetic resin, etc. are still found in the market. Absent. Handicrafts and other cloths are sometimes cut in a perfect circle, but it is difficult to cut beautifully and accurately several layers at a time. The present invention applies compass theory, high-tech sensors, and the like. Multiple paper / cloth /
A device that cuts synthetic resin, etc. using a cutter blade or rotary cutter blade, aligns with the groove installed on the rotating drum, the cutting scale of a circular metal plate, sandwiches paper or synthetic resin or cloth, and smoothly cuts it with a feed plate. Is provided.

Description

[Detailed description of the invention] [Technical field to which the invention belongs]

In the present invention, it is easy to simply draw a circle by using a compass. However, cutting paper or cloth into a perfect circle takes time and effort, and cutting scissors one by one is the best. In this invention, a plurality of papers / cloths placed on a board are stretched and fixed by a strong magnet from above and below, sandwiched by a circular metal plate with a notch scale aligned with the board scale, and without turning the compass, the circular metal at the center of the board By turning the board, cutting can be performed at once. Not only for industrial use, but also for hobbies at home and for office use, as well as for subdivided handicrafts and dressmaking, the cutter can be removed and replaced with a pencil when drawing, and demand can be expected. Fix the center axis of the compass cutter. Do not hold the compass. Turn the center circle of the board like a record board. Cut the paper and cloth fixed with a strong magnet with the board and holding circular metal plate.

[Prior art]

[0002] Simply drawing a circle is easy using a compass. However, it was not easy to cut paper and cloth into perfect circles.

[Problems to be solved by the invention]

[0003] When a large number of papers or cloths are cut in large quantities, it is due to a desire to be able to make a beautiful curve with a small amount of inaccuracy and not at once.

[Means for Solving the Problems]

[0004] Turning the compass itself does not allow the cutter to move smoothly due to the rise of wrinkles or the like on the paper or cloth, so the paper, which is a reversal of the theory of the twine camber caster, related to the structure of the car. -When cutting the cloth, when sliding the circular upper blade edge, lay the blade edge inward and lay it down, spread it upward so that it does not fall out of the scale, smoothly, and rotate the record type rotating plate for the center of the substrate. It is also possible to turn the record disc to normal rotation by turning the cutter toward the front instead of the front, or as a second method, by tilting the cutter toward the front (conventional pencil clip / insert). Use a spare blade that can be fed out after the blade edge has been discarded.

[Embodiment of the invention]

[0005] With today's advanced technology, mass production is possible, and therefore production and sales costs are also reduced.

【Example】

[0006] Same as above.

[Effect of the invention]

[0007] You can try various fields such as designs and handicrafts.

The present invention is easy to simply draw a circle by using a compass. However, it is very difficult to cut beautifully round paper or cloth, or even several sheets at a time, into a perfect circle. If such machines are used as industrial materials, handicrafts at home, and educational materials for infants at educational facilities, apparel manufacturers, etc. will also be able to apply circular skirts, capes, etc. with beautiful lines, and their use will be significantly expanded. Seem.

[Prior art]

Drawing a circle is sufficient with a compass, but machines and tools that cut paper or cloth into beautiful perfect circles are at least invisible except for machine tools. In the past, to cut paper or cloth in a round shape, it was necessary to draw a circle first and then cut it with scissors one by one.

[Problems to be solved by the invention]

[0003] I want to cut a large number (up to about 10) of a plurality of papers or cloths at once into beautiful and perfect circles without any inconsistency, but cutting by hand (scissors) is very burdensome on hands and shoulders. It is a thing. In addition, even when the fibers were cut, the fibers were stretched or the periphery was uneven, and there was a problem that it was difficult to clean up.

[Means for Solving the Problems]

[0004] As a means of cutting a perfect circle with a beautiful curve at the same time using two or three or ten sheets of paper or cloth using a razor material, a cutter blade having a sharpness of steel or a rotary cutter blade. Set the blade edge slightly inward to the left and slightly forward the tip of the blade, with the upper end of the blade angled slightly outward (the front wheel of the car / mounting specification) and set firmly. Each cutter blade is a replaceable blade specification that can be “reused by polishing”, and lead lines and pencil pincers are separately replaced for drawing lines. The blades of the cutter and rotary cutter (17) rotate and cut while being fitted into a plurality of circular grooves deeply formed on a graduated rotary drum. (11) Place a graduated semi-circular or circular metal plate so that the wrinkles of the paper or cloth and the number of stacked sheets are not misaligned. (16) Use a feed plate that fits into the base so that the paper or cloth can be smoothly fed forward.

[Embodiment of the invention]

[0005] With modern advanced technology, it is also possible to produce such machines and equipment, and if it is realized, manufacturing that has given up, circles, has advanced, and the use has expanded further. I think that the.

[Effect of the invention]

[0007] It can be greatly expected to be applied to design materials, handicrafts, educational materials for preschool educational facilities, and the like.
