The memory insertion slot is closed by a detachable tail plug (cap).

前記構成（１）では、前記ＵＳＢメモリ収容部にＵＳＢメモリを収容したり、前記収納したＵＳＢメモリを取り出したりする際には、必ず前側外筒と後側外筒とを分離したり連結したりする作業が必要になる。この作業に要する時間が長いという問題点がある。
前記構成（２）では、前記ＵＳＢメモリ収容部にＵＳＢメモリを収容したり、前記収納したＵＳＢメモリを取り出したりする際には、ＵＳＢメモリを前記メモリ挿入口からＵＳＢメモリ収容部に収納したり、前記収納したＵＳＢメモリを取り出したりする作業を行う前に必ず前記尾栓（キャップ）を取り外す作業が必要になる。この場合、前記尾栓（キャップ）は小さいので、紛失し易いという問題点がある。 In the configuration (1), when the USB memory is accommodated in the USB memory accommodating portion or the stored USB memory is taken out, the front outer cylinder and the rear outer cylinder are always separated or connected. Work is required. There is a problem that the time required for this work is long.
In the configuration (2), when the USB memory is accommodated in the USB memory accommodating portion or the stored USB memory is taken out, the USB memory is accommodated in the USB memory accommodating portion from the memory insertion port, Before removing the stored USB memory, it is necessary to remove the tail plug (cap). In this case, since the tail plug (cap) is small, there is a problem that it is easily lost.

（実施例１の作用）
前記構成を備えた本発明の実施例１の筆記具１は、図７Ａまたは図８Ａのように、スライダ支持ケース３にスライダ４、リターンバネ５および筆記用芯部材６を組付けた状態で、前記スライダ支持ケース３を後部外筒２の前端貫通口２２から後部外筒２内部に挿入する。そのとき、図１Ａ、図１Ｂに示すように、スライダ支持ケース３の３個の仕切部材３７の外側面に形成された被係止溝３７ａが、後部外筒２内側面に形成されたリング状係止部２３に係合する。この状態では、スライダ支持ケース３は後部外筒２内部で回転可能であるが、軸方向（前後方向）の移動は不可能である。
その状態では図１Ａ、図１Ｂに示すように、スライダ支持ケース３の前端部の円筒外側面に形成されたオスネジ３１（図５参照）は、後部外筒２の前端貫通口２２から前方に突出している。
前記スライダ支持ケース３の前端部外側面に形成されたオスネジ３１に、前部外筒７の後端部内周面に形成されたメスネジ７４を螺合させることにより、スライダ支持ケース３に前部外筒７を着脱可能に連結することができる。前記連結した状態（オスネジ３１およびメスネジ７４を締めつけた状態）では、スライダ支持ケース３および前部外筒７は相対移動不可能である。なお、オスネジ３１およびメスネジ７４を緩めた状態ではスライダ支持ケース３および前部外筒７は相対回転可能となる。 (Operation of Example 1)
As shown in FIG. 7A or 8A, the writing instrument 1 according to the first embodiment of the present invention having the above-described configuration has the slider 4, the return spring 5, and the writing core member 6 assembled to the slider support case 3, The slider support case 3 is inserted into the rear outer cylinder 2 from the front end through-hole 22 of the rear outer cylinder 2. At that time, as shown in FIGS. 1A and 1B, a locked groove 37 a formed on the outer surface of the three partition members 37 of the slider support case 3 is formed in a ring shape formed on the inner surface of the rear outer cylinder 2. Engage with the locking portion 23. In this state, the slider support case 3 can rotate inside the rear outer cylinder 2, but cannot move in the axial direction (front-rear direction).
In this state, as shown in FIGS. 1A and 1B, the male screw 31 (see FIG. 5) formed on the cylindrical outer surface of the front end portion of the slider support case 3 projects forward from the front end through-hole 22 of the rear outer cylinder 2. ing.
By screwing a female screw 74 formed on the inner peripheral surface of the rear end portion of the front outer cylinder 7 to the male screw 31 formed on the outer surface of the front end portion of the slider support case 3, the slider support case 3 is fitted with a front outer portion. The cylinder 7 can be detachably connected. In the connected state (in a state where the male screw 31 and the female screw 74 are tightened), the slider support case 3 and the front outer cylinder 7 are not relatively movable. In the state where the male screw 31 and the female screw 74 are loosened, the slider support case 3 and the front outer cylinder 7 can be rotated relative to each other.

前記オスネジ３１およびメスネジ７４を締めつけてスライダ支持ケース３および前部外筒７を連結した状態では、スライダ支持ケース３の回転位置規制部材３３（図５Ｂ、図５Ｃ、図６Ｃ〜図６Ｅ参照）が、後部外筒２の回転位置規制部材収容部２８（図３Ｃ、図４Ｅ参照）内で回転可能である。すなわち、回転位置規制部材３３が回転範囲規制用突出部２７に係合するまで、スライダ支持ケース３は後部外筒２内部で回転可能である。
したがって、前記スライダ支持ケース３および前部外筒７を連結した状態で、スライダ支持ケース３および前部外筒７は、後部外筒２に対して所定の角度範囲（３６０°未満の範囲）内で回転可能である。したがって、後部外筒２に対して、スライダ支持ケース３および前部外筒７を回転させると、スライダ支持ケース３に支持されたスライダ４の傾斜面４４（図１０Ａ、図１１Ｄ参照）は、後部外筒２内面に形成したスライダ移動用ガイド２６の傾斜面２６ｂ（図３Ｃ参照）と係合し、傾斜面２６ｂに押されて、前後方向にスライド移動する。このとき、複数の筆記用芯部材６の前端部を前部外筒７の前端開口７１から順次出没させることができる。 In the state where the male screw 31 and the female screw 74 are tightened and the slider support case 3 and the front outer cylinder 7 are connected, the rotational position restricting member 33 of the slider support case 3 (see FIGS. 5B, 5C, and 6C to 6E). The rotary position restricting member accommodating portion 28 (see FIGS. 3C and 4E) of the rear outer cylinder 2 is rotatable. That is, the slider support case 3 can rotate inside the rear outer cylinder 2 until the rotational position restricting member 33 is engaged with the rotation range restricting protrusion 27.
Therefore, in a state where the slider support case 3 and the front outer cylinder 7 are connected, the slider support case 3 and the front outer cylinder 7 are within a predetermined angle range (less than 360 °) with respect to the rear outer cylinder 2. It can be rotated with. Therefore, when the slider support case 3 and the front outer cylinder 7 are rotated with respect to the rear outer cylinder 2, the inclined surface 44 (see FIGS. 10A and 11D) of the slider 4 supported by the slider support case 3 becomes the rear part. It engages with the inclined surface 26b (see FIG. 3C) of the slider moving guide 26 formed on the inner surface of the outer cylinder 2, and is pushed by the inclined surface 26b to slide in the front-rear direction. At this time, the front end portions of the plurality of writing core members 6 can be made to appear and disappear sequentially from the front end opening 71 of the front outer cylinder 7.

前記筆記用芯部材６の交換を行う際には、前記オスネジ３１およびメスネジ７４を緩めて、後部外筒２に支持されたスライダ支持ケース３から前部外筒７を離脱させる。その状態でスライダ支持ケース３の前端（図１参照）から突出している筆記用芯部材６を前方に引っ張ることにより、筆記用芯部材６をスライダ４から引き抜くことができる。
新しい筆記用芯部材６を前部外筒７スライダ４に装着するには、スライダ支持ケース３の前端から筆記用芯部材６を挿入する。前記スライダ支持ケースの芯部材貫通孔３４ａは、前記複数の筆記用芯部材６の全てが貫通する１個の貫通孔により形成されているので、複数の筆記用芯部材６が貫通する大きさを有している。したがって、前記１個の貫通孔により形成された芯部材貫通孔３４ａは、複数の筆記用芯部材６がそれぞれ貫通する複数の芯部材貫通孔を形成した場合に比較して、芯部材貫通孔３４ａの形状が大きいので、前記芯部材貫通孔３４の内側に筆記用芯部材６の後端を容易に挿入することができる。前記芯部材貫通孔３４ａの内側に挿入された筆記用芯部材６の後端は芯部材貫通孔３４ａの内周面により前記スライダガイド溝３５にガイドされる。 When the writing core member 6 is replaced, the male screw 31 and the female screw 74 are loosened, and the front outer cylinder 7 is detached from the slider support case 3 supported by the rear outer cylinder 2. In this state, the writing core member 6 can be pulled out of the slider 4 by pulling the writing core member 6 protruding from the front end (see FIG. 1) of the slider support case 3 forward.
To attach the new writing core member 6 to the front outer cylinder 7 slider 4, the writing core member 6 is inserted from the front end of the slider support case 3. Since the core member through-hole 34a of the slider support case is formed by a single through-hole through which all of the plurality of writing core members 6 penetrates, the size of the plurality of writing core members 6 to penetrate is large. Have. Accordingly, the core member through-hole 34a formed by the one through-hole is compared with a case where a plurality of core member through-holes through which the plurality of writing core members 6 respectively penetrate is formed. Since the shape of is large, the rear end of the writing core member 6 can be easily inserted inside the core member through hole 34. The rear end of the writing core member 6 inserted inside the core member through hole 34a is guided by the slider guide groove 35 by the inner peripheral surface of the core member through hole 34a.

このため、筆記用芯部材６をスライダガイド溝３５に、容易に挿入することができるので、筆記用芯部材６を前記スライダ４の芯部材装着孔４１に容易に装着することができる。前記スライダ４の芯部材装着孔４１に後端部が装着された前記筆記用芯部材６は、後部外筒２の前端貫通口２２内側に配置されたスライダ支持ケース３を前後に移動可能に貫通する。後部外筒２の前端貫通口２２を前後に移動可能に貫通する前記筆記用芯部材６は、前記後部外筒２の前端貫通口２２が前部外筒７の後端貫通口７２（図１２Ｃ参照）に接続した状態では、前部外筒７の後端貫通口７２を前後に移動可能に貫通する。その状態では、複数の筆記用芯部材６の前側部分は前部外筒７内部に収容されており、その状態で前方に移動した筆記用芯部材６は前部外筒の前端開口７１から前方に突出して筆記可能な状態となる。   For this reason, since the writing core member 6 can be easily inserted into the slider guide groove 35, the writing core member 6 can be easily mounted in the core member mounting hole 41 of the slider 4. The writing core member 6 having the rear end portion mounted in the core member mounting hole 41 of the slider 4 penetrates the slider support case 3 disposed inside the front end through-hole 22 of the rear outer cylinder 2 so as to be movable back and forth. To do. The writing core member 6 that passes through the front end through-hole 22 of the rear outer cylinder 2 movably back and forth is such that the front end through-hole 22 of the rear outer cylinder 2 is the rear end through-hole 72 of the front outer cylinder 7 (FIG. 12C). In the state of being connected to (see), it penetrates the rear end through-hole 72 of the front outer cylinder 7 so as to be movable back and forth. In this state, the front side portions of the plurality of writing core members 6 are accommodated in the front outer cylinder 7, and the writing core member 6 moved forward in that state is forward from the front end opening 71 of the front outer cylinder. It will be in a state where it can write by protruding.

前記円筒状の後部外筒２の後部内側にはカートリッジ収容部２０が形成されており、カートリッジ収容部２０には、内側に突出する円弧状のカートリッジ係止部２４と、軸方向に延びるカートリッジガイド部２５が形成されている。したがって、カートリッジ着脱口２１から筒状カートリッジ９を挿入したとき、カートリッジガイド部２５は、筒状カートリッジ９の被ガイド部９１ｄ（図１４参照）と係合して、筒状カートリッジ９を軸方向（前後方向）にガイドするので、カートリッジ収容部２０内での筒状カートリッジ９の回転位置を所定の回転位置に保持することができる。また、前記カートリッジ係止部２４は、筒状カートリッジ９が挿入された時に凹部（被係止部）９１ｃと係合して、筒状カートリッジ９の軸方向の位置決めを行う。
また、前記複数のスライダ４の後端部およびスライダ支持ケース３の仕切部材３７の後端部（すなわち、スライダ支持ケース３の後端部）は、前記筒状カートリッジ９の前端円筒部９１の内部に挿入されているので、筆記具１の長さを短くすることができる。 A cartridge housing portion 20 is formed inside the rear portion of the cylindrical rear outer cylinder 2, and the cartridge housing portion 20 includes an arcuate cartridge locking portion 24 protruding inward and a cartridge guide extending in the axial direction. A portion 25 is formed. Therefore, when the cylindrical cartridge 9 is inserted from the cartridge attaching / detaching port 21, the cartridge guide portion 25 is engaged with the guided portion 91d (see FIG. 14) of the cylindrical cartridge 9, and the cylindrical cartridge 9 is moved in the axial direction (see FIG. 14). Since the guide is performed in the front-rear direction, the rotational position of the cylindrical cartridge 9 in the cartridge housing portion 20 can be held at a predetermined rotational position. The cartridge locking portion 24 engages with a recess (locked portion) 91c when the cylindrical cartridge 9 is inserted, thereby positioning the cylindrical cartridge 9 in the axial direction.
Further, the rear end portions of the plurality of sliders 4 and the rear end portion of the partition member 37 of the slider support case 3 (that is, the rear end portion of the slider support case 3) are arranged inside the front end cylindrical portion 91 of the cylindrical cartridge 9. The length of the writing instrument 1 can be shortened.

18 and 19, the writing instrument 100 of the second embodiment has a front outer cylinder 101. A conical member 102 is screwed to the front end portion of the front outer cylinder 101. A hollow inner cylinder 103 is screwed to the rear end portion of the front outer cylinder 101. A cam tube housing portion 103 a is provided at the rear end portion of the hollow inner tube 103. A grip rubber 104 is mounted on the outer periphery of the front outer cylinder 101.

前記中空内筒１０３の外側面には後部外筒１０６が回転可能に装着されている。前記前部外筒１０１と後部外筒１０６とにより実施例２の筆記具１００の外筒（１０１＋１０６）が構成されている。
前記後部外筒１０６には軸方向の中間部に仕切壁１０６ａが形成されており、仕切壁１０６ａにはネジ孔１０６ｂが形成されている。前記後部外筒１０６の前記仕切壁１０６ａよりも後側の内側にはメモリ収容孔１０６ｃが形成されている。前記メモリ収容孔１０６ｃの内側面には軸方向に延びる一対のメモリガイド溝（メモリガイド部）１０６ｄ，１０６ｄと、軸に垂直な線状突起部により形成されるメモリ係止部１０６ｅ，１０６ｅとが形成されている。メモリ係止部１０６ｅ，１０６ｅは、後述するＵＳＢメモリ１１２が容易に移動しないように係止する部材である。前記メモリ収容孔１０６ｃの後端（後部外筒１０６の後端）にはメモリ挿入口１０６ｆ（図１９参照）が形成されている。 A rear outer cylinder 106 is rotatably mounted on the outer surface of the hollow inner cylinder 103. The front outer cylinder 101 and the rear outer cylinder 106 constitute an outer cylinder (101 + 106) of the writing instrument 100 of the second embodiment.
The rear outer cylinder 106 is formed with a partition wall 106a at an axial intermediate portion, and the partition wall 106a is formed with a screw hole 106b. A memory accommodating hole 106c is formed on the inner side of the rear outer cylinder 106 on the rear side of the partition wall 106a. A pair of memory guide grooves (memory guide portions) 106d and 106d extending in the axial direction and memory locking portions 106e and 106e formed by linear protrusions perpendicular to the shaft are formed on the inner surface of the memory receiving hole 106c. Is formed. The memory locking portions 106e and 106e are members that lock the USB memory 112 described later so as not to move easily. A memory insertion opening 106f (see FIG. 19) is formed at the rear end of the memory accommodating hole 106c (the rear end of the rear outer cylinder 106).

前記ネジ孔１０６ｂには連結ブロック１０７の後端部１０７ａ外周に形成されたオスネジが螺合することにより、前記後部外筒１０６と連結ブロック１０７とが連結されている。そして、前記後部外筒１０６と連結ブロック１０７とは一体的に回転可能である。
前記中空内筒１０３後部のカム筒収容部１０３ａの内側にはカム筒１０８が回転可能に収容されている。カム筒１０８は後方に延びる連結軸１０８ａを有しており、前記連結軸１０８ａは前記連結ブロック１０７に相対回転不能に連結されている。したがって、後部外筒１０６が回転すると、連結ブロック１０７およびカム筒１０８が後部外筒１０６と一体的に回転する。 The rear outer cylinder 106 and the connecting block 107 are connected to each other by screwing a male screw formed on the outer periphery of the rear end 107a of the connecting block 107 into the screw hole 106b. The rear outer cylinder 106 and the connecting block 107 can rotate together.
A cam cylinder 108 is rotatably accommodated inside the cam cylinder accommodating portion 103a at the rear of the hollow inner cylinder 103. The cam cylinder 108 has a connecting shaft 108a extending rearward, and the connecting shaft 108a is connected to the connecting block 107 so as not to be relatively rotatable. Therefore, when the rear outer cylinder 106 rotates, the connecting block 107 and the cam cylinder 108 rotate integrally with the rear outer cylinder 106.

前記カム筒１０８の側壁には螺旋状カム面１０８ｂが形成されている。前記カム筒１０８の内周面には円筒状外周面を有する可動部材１０９が軸方向に移動可能に挿入されており、可動部材１０９の外周面には半径方向外側に突出し且つ軸方向に延びる板状突出部１０９ａが形成されている。前記板状突出部１０９ａの後端は前記螺旋状カム面１０８ａに当接している。また、図１８Ｅ、図１８Ｆに示すように、前記板状突出部１０９ａは前記カム筒１０８の側壁の外側に突出しており、前記中空内筒１０３に形成された軸方向に延びるスリット１０３ｂに嵌合している。
したがって、図１８Ａ、図１９Ａの状態で、後部外筒１０６を回転させるとカム筒１０８が回転する。この回転が、前記螺旋状カム面１０８ａにより可動部材１０９の板状突出部１０９ａの後端を前方に押圧する方向の回転である場合には、前記板状突出部１０９ａは前記カム筒収容部１０３ａに形成された軸方向に延びる前記図示しないスリットにガイドされて前方に移動する。
このようなにカム筒を回転させることにより可動部材を軸方向に移動させる技術は従来公知（例えば、実用新案登録公報第２５０６２９７号参照）であり、従来公知の種々の構成を採用することが可能である。 A spiral cam surface 108 b is formed on the side wall of the cam cylinder 108. A movable member 109 having a cylindrical outer peripheral surface is inserted into the inner peripheral surface of the cam cylinder 108 so as to be movable in the axial direction. The outer member protrudes radially outward from the outer peripheral surface of the movable member 109 and extends in the axial direction. A protruding portion 109a is formed. The rear end of the plate-like protrusion 109a is in contact with the spiral cam surface 108a. Further, as shown in FIGS. 18E and 18F, the plate-like protruding portion 109a protrudes to the outside of the side wall of the cam cylinder 108, and fits into an axially extending slit 103b formed in the hollow inner cylinder 103. is doing.
Therefore, when the rear outer cylinder 106 is rotated in the state of FIGS. 18A and 19A, the cam cylinder 108 rotates. When this rotation is a rotation in a direction in which the rear end of the plate-like projecting portion 109a of the movable member 109 is pressed forward by the helical cam surface 108a, the plate-like projecting portion 109a is the cam tube housing portion 103a. It is guided by the slit (not shown) that extends in the axial direction and is moved forward.
