Claims

[Scope of utility model registration request]

A guide cylinder having a plurality of guide grooves is removably arranged on the tip axis, and a sliding piece is attached to the rear end of each writing body, so that these writing bodies can be freely moved in the axial direction through the guide grooves of the guide cylinder. A guide ring that is fitted and further provided with a groove on the outer periphery at the front end position of the guide groove of the guide tube, has a protrusion that fits into the guide groove and forms a perfect circular part, and has a notch on a part of the outer periphery. A cylindrical cam with a cam slope on the front surface at the inner diameter of the cap is integrally movable in the rotational direction with respect to the cap and is movable in the axial direction. By fitting the cap into the guide cylinder so that it can rotate freely and not come off, and by rotating the cap with respect to the front shaft, each sliding piece can be moved on the cam slope of the cylindrical cam. It can be slid back and forth, and an internal gear is formed at the rear end of the inner diameter of the cap, and a knock bar (button gear) is fitted into it, and the knob protrudes from the rear end of the cap. By knocking, the rotor (rotating protruding member) located on the front surface of the knocking rod is rotated, and the teeth of the rotor are engaged with the teeth of the internal gear, or inserted into the grooves, and the rotor is further rotated. By moving the cylindrical cam located at the front forward or backward,
A compound writing instrument characterized in that the writing tip part is made to protrude and retract from the tip hole of the tip shaft in conjunction with this.
