KNOCK TYPE WRITING UTENSIL

PROBLEM TO BE SOLVED: To provide a knock type writing utensil which allows mechanical pencils and pencils other than the mechanical pencils to be alternatively used as refill, and enables the mechanical pencil and the other pencils other than the mechanical pencil to project and retract and a writing lead of the mechanical pencil to be fed out.SOLUTION: A knock type writing utensil comprises a barrel 4, one writing body 5, and first operating members 30 and 60 and a second operating member 20 which can be manipulated by a knock operation of pressing the members forward. where the writing body 5 can be switched between a writing position where the body is engaged with a front part of the utensil and a non-writing position where the body is disengaged therefrom and moved rearward, and mechanical pencils and pencils other than the mechanical pencil can be alternatively used as the writing body 5. When the mechanical pencil is used as the writing body 5, a writing lead thereof is fed out without releasing the engagement by the knock operation on the first operating members 30 and 60 at the writing position of the writing body 5, and the engagement is released by the knock operation on the second operating member 20 so that the writing body 5 is moved to the non-writing position.SELECTED DRAWING: Figure 2 【課題】リフィルとしてシャープペンシル及びシャープペンシル以外を択一的に使用可能なノック式筆記具において、シャープペンシル及びシャープペンシル以外の出没並びにシャープペンシルの筆記芯の繰り出しが可能なノック式筆記具を提供する。【解決手段】軸筒４と、１つの筆記体５と、前方へ押圧するノック操作可能な第１操作部材３０、６０及び第２操作部材２０とを具備し、筆記体５が前方で係合した筆記位置と係合が解除されて後方へ移動した非筆記位置とを切り替え可能であり、筆記体５として、シャープペンシル及びシャープペンシル以外を択一的に使用可能なノック式筆記具が、筆記体５がシャープペンシルのときには、筆記体５の筆記位置において、第１操作部材３０、６０のノック操作によって係合が解除されることなく筆記芯の繰り出しが行われ、第２操作部材２０のノック操作によって係合が解除されて筆記体５が非筆記位置に移動する。【選択図】図２
