201109188 形成，筆頭4、前軸7、接頭構件8是由黃銅等的金屬構件 所形成，握柄3是由矽材料的擠壓成形所形成。 此外，關於書寫具1的軸筒等（軸筒本體2、握柄3、 筆頭4、前軸7、接頭構件8、環構件9)，爲已知的眾所周 知的技術，即揭示在日本特開2〇〇4 — 90269號等。 在書寫具1的內部，書寫芯的原子筆筆芯10設有3根。 在各原子筆筆芯10的後端，安裝有滑動擋塊11»滑動擋塊 11是形成前方圓筒狀，原子筆筆芯10的後端部位的一部分 爲可裝卸地壓入嵌合。再者，在軸筒本體2的內部形成有 將滑動擋塊11朝書寫具1 (軸筒本體2)的長方向引導的導 引部2a。在導引部2a的前方設有分隔3根原子筆筆芯1〇的 分隔部2 a 1。在分隔部2 a 1與滑動擋塊1 1的前端之間，彈推 手段的螺旋彈簧12呈彈發設置。分隔部2al是相對於軸筒 本體2被固定，所以滑動擋塊1 1被往後方彈推。 在軸筒本體2的後端部，轉動凸輪構件5可轉動地設置 。轉動凸輪構件5的前方部位是整體形成圓筒狀，且在端 部形成有傾斜面5 a。該傾斜面5 a與滑動擋塊1 1的從動部 1 1 a可滑動地卡合。換言之，從動部1 1 a是沿著傾斜面5 a滑 動。因此，藉由轉動操作轉動凸輪構件5，滑動擋塊11 ( 從動部Π a )沿著傾斜面5a相對移動。而且，滑動擋塊i j 是藉由導引部2 a僅朝書寫具1的長方向引導，所以一原子 筆筆芯10的筆尖從筆頭4的開口被依序反覆輸出。 此外，關於以上的原子筆筆芯10等的書寫芯的反覆輸 出機構，爲已知的眾所周知的技術，即揭示在日本特開 -9 - 201109188 2001 — 7 1 679號等》 在轉動凸輪構件5(操作部50)的外周面上形成有支 撐筆夾6的支點6 a的台座部5b。在台座部5b設有孔部5bl， 插入固定有板簧13的一端，藉由將另一端卡止在筆夾6, 構成將筆夾6被板簧13挾持。藉此，筆夾6可以支點6a爲中 心可開閉地進行操作。 關於形成可開閉的筆夾6的構造，爲已知的眾所周知 的技術，即揭示在日本特開2001 — 146094號等。 另一方面，在轉動凸輪構件5的後方部位設有操作部 50。在操作部50設有USB端子槽51。在該USB端子槽51插 入有USB連接機器100。 本實施例的USB連接機器100爲圖4所示者，可插入各 種容量的記憶卡（半導體儲存器）（例如極細小的SD卡 等）來使用的所謂的USB記憶體配接器。USB連接機器100 (USB記憶體配接器）是由本體部101與USB連接端子102 所構成。在被設置在本體部的一側面的溝槽部l〇la插入未 圖示的記憶卡，藉由將另一端的USB連接端子102同樣連 接到未圖示的個人電腦等的USB連接口，可作爲外部記憶 媒體（所謂USB儲存器）來使用。可依據使用者的使用用 途等選擇各種容量的記憶卡，或想要以個人電腦等進行讀 取/閱覽等已被插入在行動電話等的記憶卡的資訊時來使 用。 USB連接端子1〇2及設置在USB連接端子102的卡止孔 1 0 2 a，是依據U S B規格（A類型）所形成者。因此，即使 -10- 201109188 是在本實施例.所例示的USB連接機器100以外的USB連接機 器（USB儲存器等），USB連接端子102的大小等也是形成 一樣。根據USB規格，卡止孔l〇2a，是在圖示的一面及未 圖示的相反側的面的各面各設有兩處（合計4處）° 此外，本體部1 〇 1的對向的側面1 〇 1 b，是形成凹狀的 圓弧狀。藉此，形成以使用者的手指（拇指與食指）容易 拿著的構造。 另一方面，在USB端子槽51內設有可分別與設置在前 述的USB連接端子102的4處的卡止孔l〇2a卡合對應的卡止 凸部51a(參閱圖2(b)及圖3)。卡止凸部51a的書寫具1 的長方向的兩傾斜側面5 1 a 1，是將傾斜角設定成銳角。藉 此，與卡止孔102 a的卡合順暢地進行，且也不會有在USB 連接端子102的前端削掉微小形成的卡止凸部51a的情況。 再者，USB端子槽51的橫寬W及高度T(參閱圖3)是設定 成與對應的USB連接端子102的各側面接近或接觸。因此 ，構成引導USB連接端子102插入，所以卡止孔l〇2a與卡 止凸部51a確實卡合。 兩組的卡止凸部5 1 a之中，在與筆夾6設置在相反側的 卡止凸部51a的下方（書寫具1的外周方向）形成有空間部 52。該空間部52是從操作部50的兩側面（朝向筆尖的左右 的方向）朝向內部開設成孔狀而被形成，且側面觀看形成 長孔狀（參閱圖1 )。而且，在與筆夾6設置在相反側的1 組的卡止凸部5 1 a間的下方（書寫具1的外周方向）（換言 之，對向的空間部52間）形成有隔開空間部52的壁部53。 -11 - 201109188 如此，設置空間部52的方式，被設置在空間部52的上 方（書寫具1的中心側）（換言之，與筆夾6相反側）的卡 止凸部51a，在插入USB連接端子1〇2之際，藉由USB連接 端子102的一側面擱在卡止凸部51a的上面進行推壓，而推 入空間部52側。而且，卡止凸部51a與卡止孔102a卡合時 ，恢復到固定位置。換言之，與筆夾6相反側的卡止凸部 51a，是支撐與筆夾6相反側的卡止凸部51a的基部51a2發 揮樞紐效果而與卡止孔102a卡合。因此，也幫助了卡止凸 部5 1 a的傾斜面5 1 a 1的作用效果，不僅插入觸感更滑順， 且可防止以USB連接端子102的前端削掉形成微小的卡止 凸部51 a等的不好的情形。再者，由於藉著壁部53支撐基 部51a2，所以基部51a2作用而更顯著地發揮樞紐效果。 USB規格（A類型）的插孔（換言之，設置在個人電 腦等的USB連接口）的防護罩，通常，板金加工具導電性 的銅合金製的金屬板而形成矩形筒狀。而且，與USB連接 機器100的插頭（USB連接端子102)的卡止孔102a卡止的 卡止爪，是將一端固定在防護罩的矩形筒狀的長邊側的側 面，並將周圍沖切加工而形成略三角形狀（未圖示）。可 是，USB連接機器100以容易攜帶作爲而欲安裝在書寫具 時，在插孔不需要通常使用的金屬製的防護罩。於此，採 用本發明的構成，進一步在書寫具藉由通常所使用的樹脂 成形品形成USB端子槽51的方式，藉此，不需使用金屬製 的防護罩，可達成利用USB連接端子1〇2的卡止孔l〇2a的 卡止構造。因此，可提供不需如習知技術，在USB連接機 -12- 201109188 器側採用特別的構造，且在書寫具側也不需採用特殊複雜 的構造，可容易攜帶USB連接機器的書寫具。而且，由於 可以將USB連接機器以安裝在設置在個人電腦等的USB連 接口的相同的要領安裝到書寫具，所以裝卸操作直覺上容 易。 本實施例中，進一步在筆夾6側的兩個卡止凸部5 1 a間 設置溝部51b。藉此，因某些的原因造成USB連接機器1〇〇 不能取出之際，將形成鑰匙狀的銷等插入溝部5 1 b，可勾 住USB連接端子102的前端，強制取出USB連接機器100。 再者，在轉動凸輪構件5的後方部位（U S B端子槽5 1 )與轉動凸輪構件5的前方部位之間，設置隔開兩者的隔 開壁54。藉此，即使萬一發生從原子筆筆芯1 〇漏出墨水的 情況時，也可防止USB連接機器100的污損。再者，在前 方部位側形成凸狀（換言之，後方部位側形成凹狀）的方 式，可在後方部位側的凹部設置射出成形時的澆口位置、 或設置產品編號等的刻印等。 再者，本實施例中，設有與USB端子槽51的溝槽開口 部矩形狀長邊側對向，呈略平板狀朝向後方的平板狀突出 部55。平板狀突出部55間的距離，是配合USB連接機器 100的本體部101的厚度，設定成平板狀突出部55的對向的 面與本體部101的側面接近或接觸。因此，藉由本體部1〇1 配置在平板狀突出部55間，USB連接機器1〇〇在本體部ιοί 也可被支撐，所以可更穩定安裝USB連接機器100。再者 ’由於平板狀突出部5 5間的側面（朝向筆尖時的左右的側 -13- 201109188 面）開口，所以容易握住前述USB連接機器100的本體部 101的圓弧狀的側面101b，所以USB連接機器1〇〇的裝卸的 操作性更進一步的提昇。 此外，通常本體部101的厚度，是形成的比USB連接 端子102的厚度更厚，而不會有與USB連接端子102干涉的 虞慮β 本發明中，是以一零件一體構成含有安裝USB連接機 器100的USB端子槽51等的操作部50、與含有使滑動擋塊 1 1朝前後方向滑動的傾斜面5a等的前方部位，所以書寫具 1的組裝之際容易組裝，可降低製造成本。再者，由於可 由一體的樹脂的射出成形形成，所以也具有創作性。而且 更進一步，由於是在轉動凸輪構件5 (操作部50)設置筆 夾6，所以具有容易轉動操作的優點。尤其是，如本實施 例，筆夾6爲被台座5b所支撐的開閉操作式的筆夾6時，由 於高度變高，所以變的更容易轉動操作。 以上，雖詳細說明了本發明的實施例，但本發明並不 限定於此，在不變更本發明的要旨的範圍內可適當變更。 例如，也可僅將轉動凸輪構件5的操作部50設置在書 寫芯只搭載1根的書寫具的後端等。 設置在卡止凸部51a的下方的空間部52，雖設置在與 筆夾6相反側的卡止凸部5 1 a，但也可設置在筆夾6側的卡 止凸部5 1 a，也可僅設置在筆夾6側。但是，僅在一方側的 卡止凸部5 1 a設置空間部52，所以可構成容易發揮樞紐效 果。 -14- 201109188 再者，也可不構成壁部53，以空間部52作爲貫通孔。 此時，調整基部5 1 a2的厚度，設定最適合的樞紐效果。可 是因射出成形時的收縮等的問題，會有成形條件設定困難 的情況。 【圖式簡單說明】 [圖1]表示本發明的書寫具的整體的前視圖。 [圖2 ]( a )圖1縱剖視圖、（b )爲（a )的要部放大 縱剖視圖。 [圖3 ]圖2 ( a )的（I ί〗）—（丨丨〗）線剖視圖。 [圖4]表示USB連接機器的一個例子的圖。 【主要元件符號說明】 1 :書寫具 2 :軸筒本體 2a :導引部 2al :分隔部 3 :握柄 4 :筆頭 5 :轉動凸輪構件 5 a :傾斜面 5b :台座部 6 :筆夾 6a :支點部 -15- 201109188 7 :前軸 8 :接頭構件 9 :環構件 10 :原子筆筆芯 1 1 :滑動擋塊 1 1 a :從動部 1 2 :螺旋彈簧 13 :板簧 5 0 :操作部 5 1 : U S B端子槽 5 1 a :卡止凸部 5 1 a 1 :傾斜側面 51b :溝部 5 2 :空間部 5 3 :壁部 54 :隔開壁 5 5 :平板狀突出部 100 : USB連接機器 101 :本體部 1 0 1 a :溝槽部 102 : USB連接端子 10 2a:卡止孔BACKGROUND OF THE INVENTION 1.

A memory card (not shown) is inserted into the groove portion 10a provided on one side of the main body portion, and the USB connection terminal 102 at the other end is similarly connected to a USB connection port such as a personal computer (not shown). Used as an external memory medium (so-called USB storage). It is possible to select a memory card of various capacities depending on the user's use or the like, or to use a personal computer or the like to read/read a message such as a memory card inserted in a mobile phone. The USB connection terminal 1〇2 and the locking hole 1 0 2 a provided in the USB connection terminal 102 are formed in accordance with the U S B specification (type A). Therefore, even if -10-201109188 is a USB connection device (USB storage device or the like) other than the USB connection device 100 exemplified in the present embodiment, the size and the like of the USB connection terminal 102 are also formed. According to the USB standard, the locking hole l〇2a is provided in two places (four in total) on each side of the surface on the opposite side and not shown, and the opposite direction of the main body 1 〇1 The side 1 〇 1 b is a concave arc shape. Thereby, a configuration in which the user's fingers (thumbs and forefingers) are easily held is formed. On the other hand, the USB terminal groove 51 is provided with a locking convex portion 51a that is engageable with each of the locking holes 110a provided in the four USB connection terminals 102 (see FIG. 2(b) and image 3). The two inclined side faces 5 1 a 1 in the longitudinal direction of the writing instrument 1 of the locking convex portion 51a set the inclination angle to an acute angle. Therefore, the engagement with the locking hole 102a is smoothly performed, and the slightly formed locking convex portion 51a is not cut off at the tip end of the USB connection terminal 102. Further, the lateral width W and the height T (see Fig. 3) of the USB terminal slot 51 are set to be close to or in contact with the respective side faces of the corresponding USB connection terminal 102. Therefore, since the guide USB connection terminal 102 is inserted, the locking hole 10a is reliably engaged with the locking convex portion 51a. Among the locking projections 5 1 a of the two groups, a space portion 52 is formed below the locking convex portion 51a on the opposite side of the pen holder 6 (the outer circumferential direction of the writing instrument 1). The space portion 52 is formed in a hole shape from both side faces of the operation portion 50 (toward the left and right directions of the pen tip), and is formed in a long hole shape when viewed from the side (see Fig. 1). Further, a space portion is formed below (between the outer peripheral directions of the writing instrument 1) (in other words, between the opposing space portions 52) between the pair of locking convex portions 51a disposed on the opposite side of the pen holder 6 (in the outer circumferential direction of the writing instrument 1) Wall 53 of 52. -11 - 201109188 In this manner, the space portion 52 is provided so as to be inserted in the USB connection in the locking convex portion 51a provided above the space portion 52 (the center side of the writing instrument 1) (in other words, on the side opposite to the pen holder 6). At the time of the terminal 1〇2, one side surface of the USB connection terminal 102 is pressed against the upper surface of the locking convex portion 51a, and is pushed into the space portion 52 side. Further, when the locking convex portion 51a is engaged with the locking hole 102a, it returns to the fixed position. In other words, the locking convex portion 51a on the opposite side of the pen holder 6 is a base portion 51a2 that supports the locking convex portion 51a on the opposite side of the pen holder 6, and engages with the locking hole 102a in a pivotal manner. Therefore, the effect of the inclined surface 5 1 a 1 of the locking convex portion 5 1 a is also assisted, and not only the insertion feeling is smoother, but also the front end of the USB connection terminal 102 is prevented from being cut off to form a minute locking convex portion. 51 a bad situation. Further, since the base portion 51a2 is supported by the wall portion 53, the base portion 51a2 acts to more prominently exert the pivotal effect. A shield of a USB type (A type) jack (in other words, a USB connector provided in a personal computer or the like) is usually formed into a rectangular tubular shape by a sheet metal plated with a conductive copper alloy. Further, the locking claw that is engaged with the locking hole 102a of the plug (USB connection terminal 102) of the USB connection device 100 is one end that is fixed to the side surface of the rectangular tubular long side of the shield, and is punched around. It is processed to form a slightly triangular shape (not shown). However, the USB connection device 100 does not require a commonly used metal shield at the jack when it is easy to carry. According to the configuration of the present invention, the USB terminal groove 51 is formed by the resin molded article which is generally used in the writing instrument, whereby the metal connecting terminal 1 can be realized without using a metal protective cover. The locking structure of the locking hole l〇2a of 2. Therefore, it is possible to provide a special configuration on the side of the USB connector -12-201109188 without using a conventional technique, and it is not necessary to adopt a special complicated structure on the writing instrument side, and the writing instrument of the USB connection machine can be easily carried. Moreover, since the USB connection machine can be mounted to the writing instrument in the same manner as the USB interface provided in a personal computer or the like, the loading and unloading operation is intuitively easy. In the present embodiment, the groove portion 51b is further provided between the two locking projections 5 1 a on the side of the pen holder 6 . As a result, the USB connection device 1 can be inserted into the groove portion 51b, and the front end of the USB connection terminal 102 can be hooked up to forcibly take out the USB connection device 100. Further, between the rear portion (U S B terminal groove 5 1 ) of the rotary cam member 5 and the front portion of the rotary cam member 5, a partition wall 54 that partitions both of them is provided. Thereby, even if the ink leaks from the pen stylus 1 〇 occurs, the stain of the USB connection device 100 can be prevented. Further, a convex shape (in other words, a concave shape is formed on the rear portion side) is formed on the front portion side, and a gate portion at the time of injection molding or an imprint such as a product number can be provided in the concave portion on the rear portion side. Further, in the present embodiment, a flat-shaped projecting portion 55 which faces the rectangular opening side of the groove opening portion of the USB terminal groove 51 is provided. The distance between the flat protruding portions 55 is set to match the thickness of the main body portion 101 of the USB connecting device 100, and the opposing surface of the flat protruding portion 55 is set to be close to or in contact with the side surface of the main body portion 101. Therefore, since the main body portion 1〇1 is disposed between the flat protruding portions 55, the USB connecting device 1 can be supported by the main body portion ιοί, so that the USB connecting device 100 can be mounted more stably. In addition, since the side surface between the flat protruding portions 55 (the left and right sides -13 to 201109188 toward the pen tip) is opened, it is easy to hold the arcuate side surface 101b of the main body portion 101 of the USB connecting device 100, Therefore, the operability of loading and unloading of the USB connection machine is further improved. Further, in general, the thickness of the main body portion 101 is formed thicker than the thickness of the USB connection terminal 102, and there is no fear of interference with the USB connection terminal 102. In the present invention, the integrated USB component includes a USB mounting device. The operation unit 50 such as the USB terminal slot 51 of the connection device 100 and the front portion including the inclined surface 5a for sliding the slide stopper 11 in the front-rear direction are easily assembled, and the manufacturing cost can be reduced. . Further, since it can be formed by injection molding of an integral resin, it is also creative. Further, since the pen holder 6 is provided to rotate the cam member 5 (operation portion 50), there is an advantage that the turning operation is easy. In particular, in the present embodiment, when the pen holder 6 is the opening and closing type pen holder 6 supported by the pedestal 5b, the height becomes higher, so that the turning operation becomes easier. The embodiments of the present invention have been described in detail above, but the present invention is not limited thereto, and can be appropriately modified without departing from the scope of the invention. For example, only the operation portion 50 of the rotary cam member 5 may be provided at the rear end of the writing instrument in which only one writing core is mounted. The space portion 52 provided below the locking convex portion 51a is provided on the locking convex portion 51a opposite to the pen holder 6, but may be provided on the pen holder 6 side of the locking convex portion 51a. It can also be set only on the side of the pen holder 6. However, since the space portion 52 is provided only in the locking convex portion 51a on the one side, it is possible to easily realize the pivot effect. -14- 201109188 Further, the wall portion 53 may not be formed, and the space portion 52 may serve as a through hole. At this time, the thickness of the base portion 5 1 a2 is adjusted to set an optimum pivot effect. However, it may be difficult to set molding conditions due to problems such as shrinkage during injection molding.
