摘要： PROBLEM TO BE SOLVED: To provide a compass by which drafting can be performed by using no central needle, without making a hole on a paper and there exists no possibility of piercing a finger of the hand.
SOLUTION: A leg supporting base is formed on the apex of a leg. For the leg supporting base, a transparent dome is formed at the center of a transparent disc-like flat plate, and the top part is covered with a dome-shaped lid whose top part is circularly opened. A round movable part with a larger diameter than that of the circularly opened part of the lid is connected with the apex of the leg, and it is slidably fitted into a gap between the lid and the dome.

摘要： PROBLEM TO BE SOLVED: To provide a compass which has an ultrasmall shape and enables circular or arc-shaped line drawing or cutting to be performed with accuracy.
SOLUTION: This compass is attached to a ruler so that the ruler can be used as the compass, and high dimensional accuracy is realized by using a scale on the ruler. The compass is composed of a writing instrument or a cutter fixing component A, a rotating shaft component B and the ruler C. Temporary fixing knobs are attached to the components A and B. The ruler C has a scale and is linearly formed. A forward end of the ruler C is inserted into a ruler inserting port 3 of the component A, and fixed by the temporary fixing knob 1. The component B can be slid in the longitudinal direction of the ruler C after the ruler C is inserted into a ruler inserting slit 4.

摘要： PROBLEM TO BE SOLVED: To provide a pair of compasses, with which a neat circle can be easily drawn. SOLUTION: This pair of compasses is operated with both hands by assembling a revolving leg 1 and a center leg 2 in a two-fork shape by means of a fulcrum 3 at the middle of the revolving leg 1. A circle is drawn by pushing a center lead 7 while holding a grip 4 with one hand and revolving the revolving leg 1 while holding an idle-rotation grip 5 with the other hand. The grip 4 and the center lead 7 are held vertically. A line-drawing lead 6 and the fulcrum 3 arranged on the circumferences of one and the same circle as a center. The grip 4 is located at all times just above the center lead 7.

摘要： PROBLEM TO BE SOLVED: To draw a circle without perforating a sheet by using a stationery in the case that the circuit could not be drawn conventionally without perforating the sheet by a tip of the compass in the case of drawing the circle by the compass. SOLUTION: A V-shaped small round hole 2 is opened at a center on a surface of a disc 1 made of transparent acrylic resin, and a tip of a compass is inserted into the hole to be rotated. To eliminate slipping of the disc and a sheet at the time of using the compass, an anti-slip rubber 4 is attached to a bottom of the disc.
