Claims (1)

[Claims for Utility Model Registration] 1. A guide cylinder having a plurality of guide grooves in the axial direction is fixed to a leading shaft, and a plurality of writing fonts each having a sliding piece attached to the rear end are connected to the guide cylinder by the sliding pieces. A cylindrical cam is fitted so that it can move back and forth along each guide groove, and a cylindrical cam having an axially displacing cam slope is attached to the inner surface of the cap so as to be rotatable and movable in the axial direction, and the cylindrical cam is guided. The cam slope is attached to the cylinder so that the sliding pieces of each writing body are in contact with each other, and the cap is rotatably fitted to the guide cylinder, and each sliding piece is moved onto the cam slope by rotating the cap. Each cursive can be moved back and forth by sliding it.
In addition, a knock mechanism is provided at the rear end of the cap, and the above-mentioned cylindrical cam can be moved back and forth in conjunction with the knock mechanism, and each writing can be done by rotating the cap while the cylindrical cam is advanced. The dimensions are set so that the writing part at the tip of the body can freely move in and out of the shaft tip opening, and the notch provided at the front end of the cam slope of the cylindrical cam is engaged with the sliding piece of any writing body. A compound writing instrument characterized in that the dimensions are set so that the tip writing part of the cursive body can freely come out and go in and out of the tip opening of the shaft by operating the knob. 2. In the fitting portion between the cap and the guide tube of the dual writing instrument according to claim 1, a rotary stopper piece is provided protruding from the front edge of the cap, and the guide tube is fitted with the rotary stopper piece when the cap is rotated by a required angle. A compound writing instrument characterized by having a collar that abuts against each other to restrict rotation of the cap.
