スライド式の多芯筆記具

Slide type multi-refill writing utensil

Abstract

【課題】構造が簡単で、且つ筆記時に筆記先端部が軸心に対し傾斜し難いスライド式の多芯筆記具を提供する。 【解決手段】軸筒内に複数の筆記体を配設し、各筆記体の後部に摺動体を着脱自在に連接し、前記摺動体を弾発部材により軸筒後端方向に付勢して配設するとともに、一方の摺動体を軸筒の先端開口部方向にスライドすることにより、一方の摺動体に連接した筆記体の筆記先端部を軸筒の先端開口部から突出した状態を維持し、他の摺動体を軸筒先端方向にスライドせしめることで、一方の筆記体の筆記先端部を軸筒先端開口部より没入可能な、筆記先端部を選択して出没可能なスライド式の多芯筆記具であって、前記軸筒の先端部に、前記軸筒の先端開口部から後方に向かってスリットを、周方向の異なる位置に、複数本形成したことを特徴とする。 【選択図】 図3
PROBLEM TO BE SOLVED: To provide a slide type multi-refill writing utensil in a simple construction, which can hardly allow the tilting of a writing apex part to the axis of the writing utensil during writing. SOLUTION: The slide type multi-refill writing utensil includes a plurality of writing elements arranged inside a barrel and sliders which are detachably connected with the rear part of each writing element and also, arranged as urged by a resilient member in the direction of a barrel rear end. Thus, the writing apex part of the writing element connected with one slider can be kept as projected from the apex opening of the barrel by sliding this one slider in the direction of the apex opening of the barrel. On the other hand, the writing apex part of the one writing element can be retracted from the apex opening of the barrel by making a sliding of the other slider in the direction of the barrel apex. In short, this slide type multi-refill writing utensil can make the writing apex part retractable through selecting the latter. Further, the writing utensil is characteristic in that a plurality of slits are formed at different positions in the circumferential direction toward the rear of the barrel from the apex opening, at the apex part of the barrel.
