筒部（前端筒狀部）91a。在上述前端圓筒部9U，設置有3 個狹槽（彈性調節用切除部）91b(，通過該狹槽91b，獲得適 當的彈性。在前端圓筒部91a的外周面上，形成有環狀的凹 部（被卡扣部）9 1 c。 在上述芯筒9的外側面上，設置有沿前後延伸的被導向 部91d’ 91d(參照第14C圖，第14D圖）。該被導向部91d， 91d，是在從上述筆管後部2的筒狀部件安裝口 21插入芯筒 9時，通過與形成於筆管後部2的內側面上的芯筒導向部25 (參照第3C圖，第4A圖）卡合，而實現導向。上述被導向 部9ld, 91d與芯筒導向部25卡合，由此，進行芯筒9的旋 轉位置相對於筆管後部2的定位。 在將上述芯筒9插入上述筆管後部2的內部的狀態下’ 上述筆管後部2的芯筒卡扣部24 (參照第3(：圖）與上述環 狀的凹部（被卡扣部）91c卡合，由此，進行芯筒9的軸向 (前後方向）的定位。 -44- 1337949 在上述筒狀爲91的後端部，設置有接觸部91e，該接 觸部91e與上述筆管後部2的後端的芯筒裝卸口 2 1(參照第 2圖，第3圖）的後端接觸。在上述接觸部91e的外周面上， 設置有在從筆管2的內部取出芯筒9時，手指入力用的2個 持握部（操作用凸部）91f。在上述筒狀部件91上，在上述 持握部91f的後端側，設置有尾栓裝卸部91g。 如第1A圖，第1B圖所示，在芯筒9的前端圓筒部91a 的內部，插入上述多個滑動件4的後端部和滑動件支承殻3 的分隔部件3 7的後端部（即，滑動件支承殻3的後端部）。 由此，可使複合筆具的長度不會過長。 即，在本第1實施例中，芯筒9的前端圓筒部91a，按 照可安裝於書寫用芯部件6的後端部，並可容納與上述書寫 用芯部件6成一體移動的滑動件4的後端部和滑動件支承殼 (移動體支承部件）3的後端部的方式構成，同時，按照具 有如下方式的彈性來構成，即形成於該外周面上的環狀的凹 部（被卡扣部）91c可裝卸且可卡扣於上述筆管後部2的芯 筒卡扣部24 (參照第3C圖）。 (第1實施例的作用） 在具有上述方案的本發明的第1實施例的複合筆具1 中，如第7圖，或第8圖所示，在於滑動件支承殼3中，安 裝有滑動件4，恢復彈簧5和書寫用芯部件6的狀態下，將 上述滑動件支承殼3從筆管後部2的前端通孔22’插入到筆 管後部2的內部。此時，如第1A圖，第1B圖所示’位於滑 動件支承殻3中的3個分隔部件37的外側面上的被卡扣槽 -45- 1337949 3 7a與位於筆管後部2的內側面的環狀卡扣部23卡扣。在該 狀態’滑動件支承殻3可在筆管後部2的內部旋轉，但是， 不能軸向（前後方向）移動。 在該狀態，如第1 A圖，第1 B圖所示，形成於滑動件 支承殻3的前端部的圓筒外側面上的陽螺絲31 (參照第5 圖）從筆管後部2的前端通孔22，向前方突出。 在形成於上述滑動件支承殻3的前端部外側面的陽螺 絲31上，使陰螺絲74螺合形成於筆管前部7的後端部內周 面’由此，以可裝卸的方式將筆管前部7連接於滑動件支承 殻3上。在上述連接的狀態（將陽螺絲31和陰螺絲74擰緊 的狀態）下’上述滑動件支承殻3和筆管前部7不能夠相對 移動。另外’在將陽螺絲3 1和陽螺絲7 4擇松的狀態下，上 述滑動件支承殼3和筆管前部7可相對旋轉。 在將上述陽螺絲3 1和陽螺絲7 4捧緊，將滑動件支承殼 3和筆管前部7連接的狀態下，滑動件支承殻3中的旋轉位 匱限制部件33 (參照第5B圖，第5C圖，第6C圖〜第6E 圖）可在筆管後部2的旋轉位置限制部件接納部2 8 (參照第 3C圖，第4E圖）的內部旋轉。即，滑動件支承殻3可在筆 管後部2的內部旋轉，直至旋轉位置限制部件33與旋轉範 圍限制用突出部2 7卡合。 於是，在將滑動件支承殼3和筆管前部7連接的狀態 下’該滑動件支承殼3和筆管前部7可相對於筆管後部2, 在規定的角度範圍（小於360。的範圍）內旋轉。於是，如果 相對筆管後部2 ’使滑動件支承殻3和筆管前部7旋轉則 -46- 1337949 支承於滑動件支承殻3上的滑動件4的被導向部44的傾斜 面44a (參照第1 0A圖，1 1 D )與位於筆管後部2的內側面 上的芯部件移動用導向件26的傾斜面26b (參照第3C圖） 卡合，按壓於傾斜面26b上，沿前後方向滑動。此時，可以 從筆管前部7的前端開口 71，依次使多個書寫用芯部件6 的前端部進出。 在更換上述書寫用芯部件6時，將上述陽螺絲31和陽 螺絲74擰松，使筆管前部7,與支承於筆管後部2上的滑動 件支承殼3脫離。在該狀態下，將從該滑動件支承殼3的前 端（參照第1圖）突出的書寫用芯部件6向前方拉動，由此， 可從滑動件4中，抽出書寫用芯部件6。 在將新的書寫用芯部件6安裝於滑動件4上時，從滑動 件支承殼3的前端，插入書寫用芯部件6。 由於上述滑動 件支承殼的芯部件通孔34a由可以讓所有上述多個書寫用芯 部件6穿過的1個通孔形成’故具有可以多個書寫用芯部件 6穿過的尺寸。因此，上述1個通孔形成的芯部件通孔34a 與形成多個書寫用芯部件6分別穿過的多個芯部件通孔相比 較，該芯部件通孔34a的形狀較大，故可以輕鬆將書寫用芯 部件6的後端插入芯部件通孔34a的內側。插入到該芯部件 通孔34a的內側的書寫用芯部件6的後端通過芯部件通孔 3 4a的內周面，由上述各滑動件導向槽35導向。 因此，可以很容易將書寫用芯部件6插入到各滑動件導 向槽35中，故也可以很容易將書寫用芯部件6安裝於上述 各滑動件4的芯部件安裝孔41中。其後端部安裝於上述滑 -47- 1337949 動件4的芯部件安裝孔41中的書寫用芯部件6按照可沿前 後移動的方式穿過設置於筆管後部2的前端通孔22內側的 滑動件支承殼3。在上述筆管後部2的前端通孔22與筆管 前部7的後端通孔72(參照第12C圖）連接的狀態下，按 照可沿前後移動的方式穿過筆管後部2的前端通孔22的書 寫用芯部件6按照可沿前後移動的方式穿過筆管前部7的後 端通孔72。在該狀態下’多個書寫用芯部件6的前側部分容 納於筆管前部7的內部’並且在該狀態，向前方移動的書寫 用芯部件6從筆管前部7的前端開口 71突出，而處於可書 寫的狀態。 在上述圓筒狀的筆管後部22的後部內側，設置有芯筒 接納部20’在該芯筒接納部20中，設置有向內側突出的圓 弧狀的芯筒卡扣部24，與沿軸向延伸的芯筒導向部25 6於 是，當從筒狀部件安裝口 21，插入芯筒9時，該芯筒導向部 25與芯筒9的被導向部91d(參照第14圖）卡合，沿軸向 (前後方向）對芯筒9進行導向，這樣，可將芯筒接納部20 內的芯筒9的旋轉位置保持在規定的旋轉位置。另外，在插 入芯筒9時’上述芯筒卡扣部24與凹部（被導向部）91c 卡合’以此實現芯筒9的軸向的定位。 另外’由於將上述多個滑動件4的後端部和滑動件支承 殼3中的分隔部件37的後端部（即，滑動件支承殼3的後 端部）插入到上述芯筒9的前端圓筒部91a的內部，故可 縮短複合筆具1的長度。另外，上述前端圓筒部91a，形成 於其外周面的環狀的凹部（被卡扣部）91c於上述筆管後部 -48- 1337949 2的芯筒卡扣部24(參照第3C圖）處可裝卸地及可卡扣地 進行彈性變形。因此’可利用該前端圓筒部91a的彈性•將 心同9確實卡扣於筆管後部22的芯筒接納部20內的軸向的 規定位置上。 第2實施例 第15圖爲本發明的筆具的第2實施例的主要部分的說 明圖’第15A圖爲筆具的部件的安裝狀態下的主要部分的側 面剖視圖’第1 5 B圖爲主要部分的平面剖視圖。 第16圖爲說明筒狀芯體與可裝卸於筒狀芯體後端的 USB記憶體的圖1第16A圖爲說明筒狀芯體與以可裝卸的方 式安裝於筒狀芯體後端的U S

-49- 1337949 2實施例中是相同的。 本發明的第2實施例的筆具1中，與上述第1實施例的 修改帶芯筒9的不同之處在於，設置於筆管後部2的後部內 側的芯筒接納部20中所容納的筒狀芯體（筒狀部件，即， 具有圓筒狀外側面的部件）19的結構。 在第2圖和第15圖〜第18圖中，在第1實施例中所採 用的筒狀芯體（安裝USB記憶體的筒狀部件）19包括前端 圓筒部（前端筒狀部）191及其後側的筒狀的記憶體安裝部 192° 在第15圖，第16圖中，在上述前端圓筒部191中，設 置有3個狹槽（彈性調節用切除部）19la，通過上述狹槽 191a’獲得適當的彈性。在上述前端圓筒部191的外周面上， 設置有環狀的凹部（被卡扣部）191b，在前端圓筒部191的 內側的後端’設置有分離壁1 9 1 c。該分離壁1 9 1 c以沿前後 實現液體密封（或氣體密封）的方式對上述筒狀芯體（筒狀 部件）19的內側進行分隔，在本第2實施例中，其與筒狀芯 體19成構成一體，但是也可單獨形成。另外，狹槽191&也 可省略。 在上述筒狀的記憶體安裝部1 92的內側，設置有記憶體 安裝孔192a，在其後端，設置有記憶體安裝口 192b。另外， 在記憶體安裝部192上，設置有沿軸向延伸的一對狹槽狀開 口（存儲導向部）192c，192c。在上述狹槽狀開口 192c，192c 中，通過沿圓周方向延伸而形成的凹部，形成卡扣部192d， 192d。另外，在記憶體安裝部192的後端部，設置有接觸部 1337949 I92e’該接觸部192e與上述筆管後部2的後端的芯筒裝卸 口 21(參照第2圖，第3圖）的後端接觸。 另外’在上述筒狀的記憶體安裝部192和前端圓筒部 191的外側面，設置有沿前後延伸的被導向部193，193 (參 照第16A圖’第17圖）。上述被導向部193，193爲下述的 部分’在將筒狀芯體19從上述筆管後部2的芯筒裝卸口 21 (參照第2圖，第3圖）插入時，該部分與設置於筆管後部 2的內側面的芯筒導向部25(參照第3C圖，第4A圖）卡合， 並實現導向。上述被導向部193’ 193與芯筒導向部25卡合， 由此，實現筒狀芯體19繞軸的相對筆管後部2的旋轉位置 的定位。 在將上述筒狀芯體19插入上述筆管後部2的內部的狀 態下’該筆管後部2的芯筒卡扣部24 (參照第3C圖）與上 述環狀的凹部（被卡扣部）191b卡合，由此，實現筒狀芯體 Μ的軸向（前後方向）的定位。 如上述第1Α圖’第1Β圖，在筒狀芯體19的前端圓筒 部191的內部，插入上述多個滑動件4的後端部和滑動件支 承殼3中的分隔部件37的後端部（即，滑動件支承殻3的 後端部）。由此，可防止筆具的長度過長。 在第1 8圖中，USB記憶體（功能部件）1 1包括記憶體 主體Π1和樹脂製的尾栓112。在該記憶體主體nl的前端 部’設置有USB端子（連接端子部）ma。該尾栓112的後 部具有可以讓使用者持握的抓手部n2a，與一對突出部 U2b’ U2b，該對突出部112b，112b從上述抓手部112a的 •51- 1337949 則突出。如果將上述hS憶體主體111的後端推入到該對突 出部1 1 2b ’丨1 2b之間，則將上述記憶體主體n丨的後端部 壓入到形成於上述抓手部112a的前端部的記億體嵌合孔 112c(參照第16圖）中’而被固定。在上述突出部H2b， 112b的前端，設置有被卡扣凸部Ii2d,li2d。 - 如第18圖’第16圖所示’在將上述USB記憶體11插 入到筒狀心體19的內部時’上述狹槽狀開口 i92c，192c對 該U S B記憶體1 1的記憶體主體1 1 1的—對側端部進行導 向。另外，在第17圖中，將上述USB記憶體Η插入，直 鲁 至筒狀芯體19的內部的裏側時’上述卡扣部i92tJ與被卡扣 部112d設置於軸向的相同的位置。在該狀態，如果使上述 USB記憶體11旋轉，則USB記憶體1 1中的被卡扣凸部n2d 在由筒狀芯體19的上述凹部形成的卡扣部i92(i的內部移 · 動，在該狀態下，USB記憶體11安裝於該筒狀芯體19的內 部，並且不能沿軸向移動。 (第2實施例的作用） 在具有上述方案的本發明的第2實施例的筆具1中，如 φ 第7A圖或第8A圖所示，在將滑動件4,恢復彈簧5和書寫 用芯部件6組裝於滑動件支承殻3中的狀態下，從筆管後部 2的前端通孔22,將上述滑動件支承殻3插入到該筆管後部 ， a 2的內部。此時，如第1A圖，第1B圖所示，位於滑動件支 承殻3中的3個分隔部件37的外側面上的被卡扣槽37a與 位於筆管後部2的內側面的環狀卡扣部23卡合。在該狀態 下’滑動件支承殻3可在筆管後部2的內部旋轉，但是其不 -52- 1337949 能沿軸向（前後方向）的移動。 在該狀態下’如第1 A圖，第1 B圖所示， 件支承殻3的前端部的圓筒外側面上的陽螺絲3

3和筆管前部7處於連接的狀態下，該滑動件支 旋轉位置限制部件3 3 (參照第5 B圖，第5 C圖， 第6E圖）可在筆管後部2的旋轉位置限制部件接 照第3C圖，第4E圖）的內部旋轉。即，滑動 可在筆管後部2的內部旋轉，直至旋轉位置限芾| 旋轉範圍限制用突出部27卡合。 於是’在將滑動件支承殻3和筆管前部7 下’滑動件支承殼3和筆管前部7可相對筆管後 定的角度範圍（小於360。的範圍）內旋轉。因此 筆管後部2，使滑動件支承殻3和筆管前部7旋 於滑動件支承殻3上的滑動件4的被導向部44纪 (參照第10A圖，11D)與形成於筆管後部2的 形成於滑動 1 (參照第5 上的陰螺絲 面的陽螺絲 動件支承殼 I 74擰緊的 相對移轉。 上述滑動件 動件支承殻 承殻3中的 第6C圖〜 納部2 8(參 件支承殼3 J部件3 3與 連接的狀態 部2，在規 ，如果相對 轉，則支承 丨傾斜面44a 內側面上的 -53- 1337949 芯部件移動用導向件26的傾斜面26b(參照第3C圖）卡合， 按壓於傾斜面26b上，沿前後方向滑動。此時，從筆管前部 7的前端開口 71，可依次使多個書寫用芯部件6的前端部進 出。 在更換上述書寫用芯部件6時，將上述陽螺絲31和陽 * 螺絲74擰鬆，使筆管前部7,脫離支承於筆管後部2上的滑 . 動件支承殼3。在該狀態下，將從該滑動件支承殻3的前端 (參照第1圖）突出的書寫用芯部件6向前方拉動，便可從 滑動件4中，抽出書寫用芯部件6。 · 在將新的書寫用芯部件6安裝於滑動件4上時，從滑動 件支承殼3的前端，插入書寫用芯部件6。由於上述滑動件 支承殼的芯部件通孔34a由可以讓所有上述多個書寫用芯部 件6穿過的1個通孔形成，故具有可以讓多個書寫用芯部件 ^ 6穿過的尺寸。因此，由上述丨個通孔形成的芯部件通孔34a 與形成多個書寫用芯部件6分別穿過的多個芯部件通孔相比 較，該芯部件通孔34a的形狀較大，故可輕易將書寫用芯部 件6的後端插入芯部件通孔3 4a的內側。插入到該芯部件通 ® 孔3 4a的內側的書寫用芯部件6的後端通過芯部件通孔34a 的內周面，由上述各滑動件導向槽35導向。 由於可輕易將書寫用芯部件6插入到各滑動件導向槽 -35中，因此也可輕易將書寫用芯部件6安裝於上述各滑動件 ， 4的芯部件安裝孔41中。其後端部安裝於上述滑動件4的芯 部件安裝孔41中的書寫用芯部件6按照可沿前後移動的方 式穿過安裝於筆管後部2的前端通孔22內側的滑動件支承 -54- 1337949 殻3。在上述筆管後部2的前端通孔22與筆管前部7的後 端通孔72(參照第12C圖）連接的狀態下，書寫用芯部件6 按照可沿前後移動的方式穿過筆管前部7的後端通孔72,該 書寫用芯部件6按照可沿前後移動的方式穿過筆管後部2的 前端通孔22。在該狀態下，多個書寫用芯部件6的前側部分 容納於筆管前部7的內部，在該狀態，向前方移動的書寫用 芯部件6從筆管前部7的前端開口 71，向前方突出，並處於 可書寫的狀態。 在上述圓筒狀的筆管後部2的後部內側，設置有芯筒接 納部20，在該芯筒接納部20中，設置有向內側突出的圓弧 狀的芯筒卡扣部24，與沿軸向延伸的芯筒導向部25。於是， 當從筒狀部件裝卸口 21，插入芯筒9時，該芯筒導向部25 與芯筒19的被導向部193 (參照第16A圖）卡合，沿軸向 (前後）對芯筒19進行導向，這樣，可將芯筒接納部20內 的芯筒19的旋轉位置保持在規定的旋轉位置。另外，在插 入芯筒19時，上述芯筒卡扣部24與凹部（被卡扣部）191b 卡合，並實現芯筒19的軸向的定位。 另外，由於將上述多個滑動件4的後端部和滑動件支承 殻3中的分隔部件3 7的後端部（即，滑動件支承殻3的後 端部）插入到上述芯筒19的前端圓筒部191的內部，故可 縮短筆具1的長度。 第19圖爲在上述第1實施例的筆具1的筆管後部2的 芯筒接納部（記憶體接納孔）20的內部，安裝筒狀芯體19 的狀態，將USB記憶體1 1插入到上述筒狀芯體1 9的內部 -55- 1337949 的狀態，以及將已插入的USB記憶體1 1旋轉，並且將其旋
