However, the conventional composite writing instrument having a plurality of writing core members has the same problem. In particular, the composite writing instrument is arranged in a state where a plurality of writing core members are arranged, and a slider is attached to the rear end portion of each writing core member, and the slider can be slid by a slider support case. It is supported. In order to shorten the length of such a composite writing instrument, a plurality of sliders that support rear end portions of the plurality of writing core members, a slider support case rear end portion that supports the sliders, and the cartridge are provided. Usually, it seems difficult to arrange them so as to overlap in the axial direction.
In view of the above circumstances, the present invention has the following (O01) as a technical problem.
(O01) The front end portion of the writing core member whose rear end portion is supported by the slider slidably supported by the slider support case can protrude from the front end opening portion of the outer cylinder, and the marker from the rear end opening portion of the outer cylinder In a composite writing instrument in which a cartridge such as a correction tape can be directly and detachably mounted, the length of the composite writing instrument should be shortened.

次に、前記課題を解決するために案出した本発明を説明するが、本発明の構成要素には、後述の実施例の構成要素との対応を容易にするため、実施例の構成要素の符号をカッコで囲んだものを付記する。
なお、本発明を後述の実施例の符号と対応させて説明する理由は、本発明の理解を容易にするためであり、本発明の範囲を実施例に限定するためではない。 Next, the present invention devised to solve the above problems will be described.

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 of the slider 4 supported by the slider support case 3 (see FIGS. 10A and 11D) 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、カートリッジ９の被ガイド部９１ｄ（図１４参照）と係合して、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、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、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、前記カートリッジ９の前端円筒部９１ａの内部に挿入されているので、複合筆記具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 has 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 cartridge 9 is inserted from the cartridge attaching / detaching port 21, the cartridge guide portion 25 engages with the guided portion 91d (see FIG. 14) of the cartridge 9 to guide the cartridge 9 in the axial direction (front-rear direction). Therefore, the rotational position of the cartridge 9 in the cartridge housing portion 20 can be held at a predetermined rotational position. The cartridge locking portion 24 engages with a concave portion (locked portion) 91c when the cartridge 9 is inserted, thereby positioning the cartridge 9 in the axial direction.
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 inserted into the front end cylindrical portion 91a of the cartridge 9. Therefore, the length of the composite writing instrument 1 can be shortened.
