ルにおける芯追従機構。 a chuck having a tightening ring fitted onto the head and biased longitudinally rearward by a chuck spring;
Consists of a coupling device that restricts the retreat of the tightening ring, a tip that fixes the coupling directly or via an inner shaft, and a core guide built into the tip that can be slid in the longitudinal direction to advance the chuck. In a plotter pencil that allows a lead to be fed out and the next lead to follow, a chuck guide member that is biased longitudinally rearward by a spring is slidably built into the lead guide, and is used to restrict the chuck expansion of the chuck guide member. A lead following mechanism for a plotter pencil, characterized in that the engagement hole is configured to face the front end of the chuck.
