載のコンパス。[Claims for Utility Model Registration] (1) A fulcrum member provided with a center needle at the lower end and a guide groove on the front side for guiding the sliding plate so as to be slidable in the lateral direction, and a fulcrum member provided on the sliding plate. a writing part; and an auxiliary member having a guide groove on the front side that is connected to the distal end portion of the fulcrum member and extends the guide groove, the sliding plate and the bottom of each guide groove of the fulcrum member and the auxiliary member. and each of the slide plates is provided with a long hole through which a fixing screw for fixing the slide plate to the fulcrum member or the auxiliary member is inserted so that the slide plate can be slid in the lateral direction,
The dimension between both ends of the elongated hole of the sliding plate is the dimension between the guide groove of the fulcrum member and both distal ends of the elongated hole, and the dimension between the guide groove of the auxiliary member and both proximal ends of the elongated hole. While setting the size to be larger than the sum of the dimensions, a connecting part that contacts the back side of the fulcrum member is extended to the proximal part of the auxiliary member, and a connecting part that contacts the back side of the fulcrum member is provided on the front side of the connecting part. A regulating piece is protruded from the side and restricts vertical swinging of the auxiliary member with respect to the fulcrum member, and a connecting screw is provided to pass through the elongated hole and connect the connecting piece to the fulcrum member. A compass characterized by the fact that (2) A plurality of elongated holes are provided in the auxiliary member, and the dimension between both ends of the adjacent elongated holes is set smaller than the dimension between both ends of the elongated hole of the sliding plate, and the guide groove of the auxiliary member and The sum of the dimension between both proximal ends of the proximal elongated hole and the dimension between both distal ends of the guide groove and the distal elongated hole is calculated as 2. The compass according to claim 1, wherein the compass is set to be smaller than the size of the compass. (3) The compass according to claim 1, wherein the elongated hole of the auxiliary member is provided with a large diameter insertion portion through which a fixing screw can be inserted.
