【作用】[Action]

本考案の構成は以上の通りであり、図３は筆記部の収納状態を示している。先 ず、図４に示すようにノック操作部３４の後端部３０をノックして軸先方に摺動 させ、後端部３０を仕切り３のストッパー４６に係合させると色芯筆記体４３の 筆記先端部が先軸１５の先端孔１９から突出する。この状態で先軸１５に対して 後軸１を隙間Ｓのストロークでノック（軸推移）させるとそれと連動して色芯筆 記体４３が先軸１５の段部４７に筆記先端部の段部４８が当接した状態で軸推移 するので色芯４４が繰り出される。次に、ノック操作部３３の後端部３０をノッ クして軸先方に摺動させるとノック操作部３４の突部３１、３２にノック操作部 ３３の突部が迎合してストッパー４６との係止状態を解除してノック操作部３４ と共に色芯筆記体４２の筆記先端部が軸内に没入し、代わりにノック操作部３３ の後端部がストッパー４６に係止してシャープペンシル筆記体３９の筆記先端部 が先端孔１９から突出して筆記状態となる。（図５参照）又、他のボールペン筆 記体３８や消しゴム繰出し体４１の場合も同様に作用する。 The structure of the present invention is as described above, and FIG. 3 shows a state in which the writing unit is stored. First, as shown in FIG. 4, when the rear end portion 30 of the knock operation portion 34 is knocked and slid forward of the shaft, and the rear end portion 30 is engaged with the stopper 46 of the partition 3, the color core cursive body 43 of the color core writing body 43 is removed. The writing tip portion projects from the tip hole 19 of the tip shaft 15. In this state, when the rear shaft 1 is knocked (axis transition) with respect to the front shaft 15 with the stroke of the gap S, the color core writing body 43 is interlocked with it and the step portion 47 of the front shaft 15 has a step portion at the tip of the writing. Since the axis shifts in the state where 48 contacts, the color core 44 is paid out. Next, when the rear end portion 30 of the knock operating portion 33 is knocked and slid forward of the shaft, the protruding portions 31 and 32 of the knock operating portion 34 are brought into contact with the protruding portions of the knock operating portion 33 so that the stopper 46 is formed. After the locked state is released, the writing tip of the color core writing instrument 42 with the knock operating portion 34 is immersed in the shaft, and instead, the rear end portion of the knock operating portion 33 is engaged with the stopper 46 and the mechanical pencil writing instrument is The writing tip portion 39 projects from the tip hole 19 and is in the writing state. (See FIG. 5) Also, the same applies to other ball-point pen writing bodies 38 and eraser feeding bodies 41.
