Description

加壓式筆具 Pressure pen

本發明係關於一種對油墨收容筒內之筆具用油墨組成物施加壓力之加壓式筆具。 The invention relates to a pressurized writing instrument which applies pressure to an ink composition for writing instruments in an ink containing cylinder.

以往，就該種之加壓式筆具而言，如JP2000-335173A所揭示，已知有一種下述構造：在油墨收容管之後端部設置有加壓機構，與敲擊體之推壓操作連動而將前述油墨收容管內設為加壓状態，藉此使來自書寫前端部之油墨吐出量增加，以使筆跡寬度或筆跡濃度提升。 Conventionally, as for this type of pressurized writing instrument, as disclosed in JP2000-335173A, there is known a structure in which a pressurizing mechanism is provided at an end portion of an ink containing tube and a pressing operation of a striking body The inside of the ink containing tube is set to a pressurized state by interlocking, thereby increasing the amount of ink ejected from the leading end portion of the writing to increase the width of the handwriting or the density of the handwriting.

然而，在JP2000-335173A之加壓式筆具中，於使加壓機構部作動之後，由於對油墨收容管內施加之壓力不會變化，因此有未必成為符合使用者之喜好的筆跡寬度或筆跡濃度之情形。 However, in the pressurized writing instrument of JP2000-335173A, after the pressurizing mechanism is actuated, the pressure applied to the ink containing tube does not change, so there may not be a handwriting width or handwriting that matches the user's preference Situation of concentration.

再者，就解決該問題之技術而言，在JPH08-141482A中，揭示有一種可將施加於液槽內之修正液之後端的壓力予以任意地調整之塗布具。 Furthermore, in terms of a technique for solving this problem, JPH08-141482A discloses a coating tool that can arbitrarily adjust the pressure at the rear end of the correction liquid applied to the liquid tank.

在JPH08-141482A之塗布具中，係成為下述構造：藉由使軸筒後端之旋轉體從筒內端部之槽推動部的推壓起點朝推壓終點方向段階性旋轉，而依據各段的加壓部之高度 使液槽之後端朝軸筒前方推動而階段性地壓縮液槽。 In the applicator of JPH08-141482A, the structure is as follows: The rotating body at the rear end of the shaft cylinder is rotated stepwise from the pressing start point of the slot pushing part at the inner end of the tube to the end point of the pressing step. Height of the pressurized section of the segment The rear end of the liquid tank is pushed toward the front of the shaft cylinder to compress the liquid tank in stages.

然而，在JPH08-141482A之構造中，雖在使用時能以任意之強度對液槽內進行加壓，但在使用時必須每次藉由使旋轉體旋轉而調整加壓力，並且在停止使用之際，也會有在加壓之狀態下從液塗布口產生漏液之危険性，因此必須在使旋轉體旋轉至原來之位置之後進行保管，而耗費人力時間。 However, in the structure of JPH08-141482A, although it is possible to pressurize the liquid tank with an arbitrary strength during use, it is necessary to adjust the pressure by rotating the rotating body each time during use, and to stop using it. At the same time, there is also a danger that liquid leakage may occur from the liquid application port under a pressurized state. Therefore, it is necessary to store the rotating body after rotating it to the original position, which consumes human time.

另一方面，在JP2011-235612A中揭示有一種藉由書寫時之筆壓而使加壓機構作動，並將書寫液收容管內設為加壓狀態之所謂之筆壓加壓式的原子筆。 On the other hand, JP2011-235612A discloses a so-called pen pressure press type ballpoint pen which operates a pressurizing mechanism by a pen pressure during writing and sets a pressure state in a writing liquid storage tube.

該JP2011-235612A中所述之筆壓加壓式的原子筆，由於係為在書寫時使原子筆補充筆芯藉由筆壓而後退，從而加壓機構會作動而對油墨之後端施加壓力之構造，因此為了如JPH08-141482A般調整在加壓時施加在油墨後端之壓力，必須使原子筆補充筆芯在施加有筆壓之際後退之幅度增減，而相應地難以使原子筆補充筆芯之前端部從軸筒突出之長度成為固定。 The pen pressure and pressure type ballpoint pen described in JP2011-235612A is to replenish the ballpoint pen refill by pen pressure when writing, so that the pressure mechanism will act and apply pressure to the rear end of the ink. Structure, in order to adjust the pressure applied to the back end of the ink when pressurized like JPH08-141482A, it is necessary to make the ballpoint pen refill retreat when the pen pressure is applied, and it is difficult to make the ballpoint pen accordingly The length of the front end of the refill protruding from the barrel is fixed.

然而，原子筆之把持位置係因人而有各種不同，但大多以書寫時之筆尖的位置為基準來決定把持位置。因此，使用者係必須配合筆尖之突出長度而改變把持軸筒之位置，特別是在使筆具之把持部形成止滑用之凹凸或以容易把持之方式朝內側或外側彎曲而形成時，若變更把持位置，會產生連把持感觸都會改變的問題。 However, the holding position of the ballpoint pen varies from person to person, but the holding position is mostly determined based on the position of the pen tip when writing. Therefore, the user must change the position of the holding shaft in accordance with the protruding length of the pen tip, especially when the holding part of the pen is formed into a bump for anti-slip or is bent inward or outward in an easy way. Changing the grip position causes a problem that even the grip feeling changes.

JP2009-202513A之加壓式筆具係成為下述 構造：加壓機構具備：缸體，係在後端部具有連通於內外之空氣孔；以及密閉構件，係由安裝在敲擊體之內壁的有底筒體所構成；並且，藉由敲擊體之前進，使缸體之後端部壓接於密閉構件之有底內壁來閉鎖缸體之空氣孔，並且藉由缸體之前進而壓縮被密閉之缸體內之空氣，且對油墨收容筒之後端部的空間施加壓力。 JP2009-202513A's pressurized writing instrument is as follows Structure: The pressurizing mechanism is provided with a cylinder body having air holes communicating with the inside and the outside at the rear end portion, and a sealing member composed of a bottomed cylinder mounted on the inner wall of the striking body; and Advance the striker, make the rear end of the cylinder block crimped to the bottomed inner wall of the sealing member to close the air hole of the cylinder block, and compress the air in the closed cylinder block before the cylinder block, and the ink containing cylinder The space at the rear end applies pressure.

再者，在一般之加壓式筆具中，在解除加壓狀態時，將密閉之空間予以壓縮而成之部分係有必要回復原狀。因此，在解除經加壓之空間之際，若加壓空間之壓力因油墨之消耗等而到達大氣壓附近時，會成為氣壓比大氣壓更低之負壓狀態，而有填充於油墨收容筒內之筆具用油墨朝油墨收容筒之後端側移動而發生油墨逆流之虞。作為其對策，在JP2009-202513A的加壓式筆具中，係成為下述構造：在敲擊體因線圈彈簧而朝後方被彈推，並解除加壓機構之加壓狀態之際，藉由線圈彈簧之彈推力解除缸體與密閉構件之密閉而將缸體之空氣孔予以開放，並且在將缸體內及油墨收容筒之後端部設為與大氣壓同壓之後，缸體會後退，從而在解除密閉空間之時防止其成為氣壓比大氣壓更低的負壓狀態。 Furthermore, in a general pressurized writing instrument, when the pressurized state is released, a portion formed by compressing a closed space is required to return to its original state. Therefore, when the pressurized space is released, if the pressure in the pressurized space reaches near the atmospheric pressure due to the consumption of ink, etc., it will become a negative pressure state where the air pressure is lower than the atmospheric pressure, and there will be a pressure filled in the ink containing cylinder. The ink for writing instruments moves toward the rear end side of the ink containing cylinder, and the ink may flow backward. As a countermeasure, the pressurized writing instrument of JP2009-202513A has a structure in which, when the striking body is pushed backward by the coil spring, and the pressurizing state of the pressurizing mechanism is released, The spring thrust of the coil spring releases the airtightness of the cylinder body and the sealing member to open the air hole of the cylinder body. After the cylinder body and the rear end of the ink containing cylinder are set to the same pressure as the atmospheric pressure, the cylinder body will retreat. The closed space is prevented from becoming a negative pressure state where the air pressure is lower than the atmospheric pressure.

上述之JP2011-235612A所述之筆壓加壓式的原子筆係成為下述構造：可在書寫時使原子筆補充筆芯藉由筆壓而後退，從而加壓機構會作動而對油墨之後端施加壓力，並藉由在書寫時使書寫前端部相對於紙面等反覆地抵接、分離，從而切換加壓狀態與非加壓狀態。因此， 在書寫時若原子筆補充筆芯大幅地後退則會變為非常難以書寫，所以書寫時之原子筆補充筆芯的後退量係必須設為最小限度。因此，如JP2009-202513A般之敲擊式的加壓式筆具般，由於無法藉由使敲擊體以長衝程前進來對加壓室內施加高加壓，因此藉由加壓機構而施加之壓力亦比敲擊式還小。並且，在筆壓加壓式中，由於原本就是每當書寫前端部從紙面離開時就會使加壓室之加壓狀態被重置的構造，因此具有下述優點：可藉由一次的壓縮而加壓之壓力雖低，但仍可保持大致一定之加壓狀態而進行書寫。 The pen pressure press type ballpoint pen described in JP2011-235612A mentioned above has the following structure: the ballpoint pen refill can be retreated by the pen pressure when writing, so that the pressurizing mechanism will operate to the back of the ink Pressure is applied, and the writing front end is repeatedly abutted against and separated from the paper surface or the like during writing, thereby switching between a pressurized state and a non-pressurized state. therefore, If the ballpoint pen refill retreats sharply during writing, it will become very difficult to write, so the amount of backlash of the ballpoint pen refill must be set to a minimum when writing. Therefore, like a percussion-type pressure pen like JP2009-202513A, since the percussion body cannot be advanced with a long stroke to apply high pressure to the pressure chamber, it is applied by a pressure mechanism. The pressure is also less than the percussion. In addition, in the pen pressure compression type, since the pressure state of the compression chamber is reset every time the writing front end part is separated from the paper surface, it has the following advantages: it can be compressed by one time Although the pressure of pressure is low, writing can be performed while maintaining a substantially constant pressure.

然而，在JP2011-235612A之構造中，由於是在每次書寫時重置加壓室之加壓狀態，且以一次之動作所加壓之壓力亦會變低，因此在加壓重置時產生之負壓狀態亦成為極小，但與如JP2009-202513A般之敲擊式的加壓式筆具相比較時，由於在書寫時加壓狀態被重置之次數非常多，因此會有容易將空氣從書寫前端部捲入至原子筆補充筆芯內而最後成為油墨逆流而無法書寫之狀態之虞。 However, in the structure of JP2011-235612A, since the pressurizing state of the pressurizing chamber is reset every time writing is performed, and the pressure pressurized by one action will also be lowered, it occurs when the pressurizing is reset. The negative pressure state is also extremely small, but when compared with a percussion-type pressure pen such as JP2009-202513A, the pressure state is reset a lot during writing, so it is easy to bleed air. There is a possibility that the ink will be drawn into the refill of the ballpoint pen from the leading end of the writing, and eventually the ink will flow backward and cannot be written.

本發明係鑑於上述課題而研創者，其第一目的在於提供一種可藉由筆壓對油墨收容筒內之油墨後端施加壓力之加壓式筆具，該加壓式筆具係可藉由使轉動體轉動而配合使用者之喜好來調整油墨收容筒內之加壓，並且可使在使轉動體轉動之際從軸筒前端突出之原子筆補充筆芯的前端部之突出量保持為固定。 The present invention was developed in view of the above-mentioned problems, and a first object thereof is to provide a pressurized writing instrument capable of applying pressure to a rear end of an ink in an ink containing cylinder by a pen pressure.

接著，說明藉由將轉動體6朝前方推壓(敲擊操作)而使屬於原子筆補充筆芯8之書寫前端的原子筆尖13從前軸3之前端開口部3a突出沒入的狀態。 Next, a description will be given of a state in which the ballpoint pen tip 13 belonging to the writing tip of the ballpoint pen refill 8 is pushed into the front end 3a of the front end 3 by pressing the rotating body 6 forward (knock operation).

當從第1圖之狀態將轉動體6朝前方推壓(第1圖之箭頭F方向)時，轉動體6會相對於滑移構件5前進，凸狀部6b會抵接於滑移構件5之後端，且被轉動體6推壓之滑移構件5及壓入裝設在滑移構件5之墊圈15會與轉動體6 一同抵抗敲擊用線圈彈簧16之彈壓力而前進。同時，由於轉動體6係與滑動構件22進行凸輪嵌合，因此滑動構件22會朝前方被推壓，滑動構件22會前進，從而使筒狀體18受到加壓用線圈彈簧23彈壓而前進。並且，隨著筒狀體18之前進而透過彈性構件20使原子筆補充筆芯8朝前方被推壓而前進，且原子筆尖13之前端部會從前軸3之前端開口部3a突出。此時，滑移構件5之卡掛部5a卡掛在配置於後軸2之側面的夾具9之前端部的被卡掛部9c，藉此成為使原子筆尖13之前端維持從前軸3(軸筒4)之前端開口部3a突出的狀態之第6圖的狀態。 When the rotating body 6 is pushed forward from the state shown in FIG. 1 (in the direction of arrow F in FIG. 1), the rotating body 6 advances relative to the sliding member 5, and the convex portion 6 b abuts against the sliding member 5. At the rear end, the sliding member 5 pushed by the rotating body 6 and the washer 15 installed in the sliding member 5 are pressed against the rotating body 6 Together, they advance against the spring pressure of the coil spring 16 for striking. At the same time, since the rotating body 6 is cam-fitted with the sliding member 22, the sliding member 22 is pushed forward and the sliding member 22 is advanced, so that the cylindrical body 18 is pushed forward by the coil spring 23 for pressure. In addition, as the cylindrical body 18 is pushed forward by the elastic member 20 through the elastic member 20, the front end of the ballpoint pen tip 13 protrudes from the front end opening 3 a of the front shaft 3. At this time, the hooking portion 5a of the sliding member 5 is hooked on the hooked portion 9c of the front end of the clamp 9 arranged on the side surface of the rear shaft 2, thereby maintaining the front end of the ballpoint pen 13 from the front shaft 3 (shaft Tube 4) The state of FIG. 6 in a state where the front end opening portion 3a protrudes.

在此，當推壓夾具9之後端部(第6圖之箭頭G方向)，並解除卡掛於夾具9之被卡掛部9c的滑移構件5之卡掛部5a的卡掛狀態時，藉由敲擊用線圈彈簧16之彈壓力，原子筆補充筆芯8、加壓機構7、滑動構件22、滑移構件5及轉動體及6會朝後方移動而回到第1圖之狀態。 Here, when the rear end of the jig 9 is pressed (in the direction of arrow G in FIG. 6) and the hooking state of the hooking portion 5 a of the sliding member 5 which is hooked on the hooked portion 9 c of the jig 9 is released, By the spring pressure of the coil spring 16 for striking, the ballpoint pen refill 8, the pressurizing mechanism 7, the sliding member 22, the sliding member 5, and the rotating body 6 are moved backward and return to the state shown in FIG. 1.

接著，說明在本實施形態中，利用書寫時之書寫壓，透過油墨追隨體12將壓力施加在原子筆補充筆芯8內之油墨11之後端的狀態。 Next, in this embodiment, the state of the rear end of the ink 11 in the ball-point pen refill 8 is applied through the ink follower 12 using the writing pressure at the time of writing.

如第6圖及第9A圖所示，在原子筆尖13之前端從前軸3之前端開口部3a突出的狀態下，當如第7圖所示使軸筒4傾斜並保持，並對原子筆補充筆芯8之前端施加筆壓而使原子筆補充筆芯8朝第7圖之箭頭H方向後退時，滑移構件5由於卡掛部卡止於夾具9之被卡掛部9c而無法後 退，轉動體6由於相對於滑移構件5進行凸輪嵌合而無法後退，且滑動構件22由於與轉動體6進行凸輪嵌合而無法後退，因此筒狀體18會抵抗加壓用線圈彈簧23之彈壓力而與彈性構件20一同後退。並且，當在卡止於滑動構件22而停止之擋止具19之前端面19d抵接有彈性構件20之後端時，會成為空氣孔20c被前端面19d阻塞而使加壓空間21密閉之第9B圖的狀態。再者，當原子筆補充筆芯8後退而使筒狀體18後退時，彈性構件20會彈性變形，從而如第9C圖所示使加壓空間21被壓縮，而成為透過油墨追隨體12對原子筆補充筆芯8內之油墨11的後端施加壓力之第8圖的狀態。亦即，隨著原子筆補充筆芯8之後退，可藉由加壓機構7而對油墨11之後端施加壓力。 As shown in FIG. 6 and FIG. 9A, in a state where the front end of the ballpoint pen tip 13 protrudes from the front opening 3a of the front shaft 3, the shaft cylinder 4 is tilted and held as shown in FIG. 7, and the ballpoint pen is supplemented When a pen pressure is applied to the front end of the refill 8 and the ballpoint pen refill 8 moves backward in the direction of arrow H in FIG. 7, the sliding member 5 cannot be moved back because the hooking portion is locked on the hooked portion 9 c of the clamp 9. The revolving body 6 cannot be retracted due to cam fitting with respect to the sliding member 5, and the sliding member 22 cannot retreat due to cam fitting with the revolving body 6, so the cylindrical body 18 resists the coil spring 23 for pressure With the elastic pressure, it retreats with the elastic member 20. In addition, when the front end surface 19d of the stopper 19 that is locked on the slide member 22 and abuts against the rear end of the elastic member 20, the air hole 20c is blocked by the front end surface 19d and the pressurizing space 21 is closed. State of the graph. In addition, when the ballpoint pen refill 8 is retracted and the cylindrical body 18 is retracted, the elastic member 20 is elastically deformed, so that the pressurizing space 21 is compressed as shown in FIG. 9C to become a pair of penetrating ink followers 12 The ball-point pen complements the state of FIG. 8 in which pressure is applied to the rear end of the ink 11 in the refill 8. That is, as the ballpoint pen refill 8 is retracted, pressure can be applied to the rear end of the ink 11 by the pressurizing mechanism 7.

此外，藉由原子筆補充筆芯8之筆壓而進行之朝箭頭H方向之後退，會因為筒狀體18之外段部18c抵接於轉動體6之前端6g而停止。亦即，可依據外段部18c與前端6g之間隙的大小，來決定原子筆補充筆芯8可後退的長度。 In addition, the backward movement in the direction of arrow H by supplementing the pen pressure of the refill 8 with the ball pen will stop because the outer section 18 c of the cylindrical body 18 abuts against the front end 6 g of the rotating body 6. That is, the retractable length of the ballpoint pen refill 8 can be determined according to the gap between the outer section 18c and the front end 6g.

並且，當解除筆壓時，藉由加壓用線圈彈簧23之彈壓力及經變形之彈性構件20的復原力，筒狀體18及彈性構件20會朝前方(原來之位置)移動。然後，當彈性構件20之後端從擋止具19之前端面19d分離時，空氣孔20c會被開放而解除加壓空間21及原子筆補充筆芯8之後部內孔8a的密閉，成為與大氣壓同壓，而回到第7圖之狀態。 When the pen pressure is released, the cylindrical body 18 and the elastic member 20 move forward (the original position) by the elastic pressure of the coil spring 23 for pressure and the restoring force of the deformed elastic member 20. Then, when the rear end of the elastic member 20 is separated from the front end surface 19d of the stopper 19, the air hole 20c will be opened to release the sealing of the pressure space 21 and the inner hole 8a of the rear part of the ball pen refill 8 to become the same pressure as the atmospheric pressure. , And return to the state of Figure 7.

接著，說明在第6圖之敲擊狀態下，藉由使轉動體6相對於後軸2轉動而使加壓力調整機構24作動，以調整施加在油墨11之加壓力的動作。 Next, a description will be given of the operation of adjusting the pressing force applied to the ink 11 by operating the pressing force adjusting mechanism 24 by rotating the rotating body 6 relative to the rear shaft 2 in the striking state of FIG. 6.

當從第10A圖之狀態使轉動體6朝從後端側觀看的左方向(逆時計方向)旋轉而成為第10B圖之狀態時，滑移構件5係以相對於後軸2無法轉動之方式被卡止，因此如第11A圖至第11B圖所示，轉動體6之第一凸輪突起6d會沿著第一凸輪斜面從第1段部5g1朝相鄰之第2段部5g2移動。此時，轉動體6係相對於滑移構件5前進第一凸輪突起6d移動一段所成之L1的份量(參照第11A圖)，同時，藉由加壓用線圈彈簧23朝後方被彈壓之滑動構件亦前進L1的份量。 When the rotating body 6 is rotated in the left direction (counter-clockwise direction) viewed from the rear end side from the state of FIG. 10A to the state of FIG. 10B, the sliding member 5 is unable to rotate relative to the rear shaft 2 Because it is locked, as shown in FIGS. 11A to 11B, the first cam protrusion 6 d of the rotating body 6 moves along the first cam slope from the first stage portion 5g1 to the adjacent second stage portion 5g2. At this time, the rotating body 6 is moved relative to the sliding member 5 by the amount of L1 formed by moving the first cam protrusion 6d a step (refer to FIG. 11A), and at the same time, the coil spring 23 is pressed and slid to the rear by the compression coil spring 23 The building block also advances the weight of L1.

而且，由於滑動構件22以相對於筒狀體18無法轉動之方式被卡止，筒狀體18以無法轉動之方式被卡止在滑移構件5，所以滑動構件22無法相對於軸筒4轉動，因此如第12A圖至第12B圖所示，伴隨轉動體6之旋轉，轉動體6之第二凸輪突起6f係沿著滑動構件22之第二凸輪斜面22a從第1段部22b1移動至相鄰之第2段部22b2。此時，滑動構件22係相對於轉動體6後退第二凸輪突起6f移動一段所成之M1的份量(參照第12A圖)。因此，滑動構件22係藉由第一凸輪機構30而前進L1的份量，且藉由第二凸輪機構40而後退M1的份量。並且，在本實施形態中，由於構成為L1=M1，因此僅轉動體6相對於軸筒4前進L1的份量，滑動構件22之相對位置係不會相對於軸筒4 變化。並且，由於滑動構件22之位置不會改變，因此藉由加壓用線圈彈簧23朝前方被彈壓之筒狀體18的位置亦不會變化，透過彈性構件20而固定在筒狀體18之原子筆補充筆芯8相對於軸筒4之相對位置亦不會變化。因此，筒狀體18之外段部18c與轉動體6之前端6g的間隙會變為短少轉動體所前進之L1的份量，因此在施加筆壓之際，原子筆補充筆芯8可後退之長度亦會減少L1的份量。並且，由於在施加筆壓時之彈性構件20的變形量亦會減少，因此施加在加壓空間21之壓力會下降，結果，藉由使轉動體6朝左旋轉一段份，可使施加在原子筆補充筆芯8內之油墨11之後端的壓力下降。 In addition, since the sliding member 22 is locked so as not to rotate with respect to the cylindrical body 18 and the cylindrical body 18 is locked into the sliding member 5 so as not to rotate, the sliding member 22 cannot rotate with respect to the shaft cylinder 4 Therefore, as shown in FIGS. 12A to 12B, with the rotation of the rotating body 6, the second cam protrusion 6f of the rotating body 6 moves from the first stage portion 22b1 to the phase along the second cam inclined surface 22a of the sliding member 22. The adjacent second section 22b2. At this time, the sliding member 22 is a portion of the M1 formed by moving the second cam protrusion 6f backward with respect to the rotating body 6 (see FIG. 12A). Therefore, the sliding member 22 is advanced by the amount of L1 by the first cam mechanism 30 and is retracted by the amount of M1 by the second cam mechanism 40. In addition, in this embodiment, since the configuration is L1 = M1, only the amount by which the rotating body 6 advances with respect to the shaft cylinder 4 by L1, and the relative position of the sliding member 22 is not relative to the shaft cylinder 4. Variety. In addition, since the position of the sliding member 22 does not change, the position of the cylindrical body 18 which is urged forward by the coil spring 23 for pressure does not change, and the atoms fixed to the cylindrical body 18 through the elastic member 20 do not change. The relative position of the pen refill 8 relative to the shaft cylinder 4 will not change. Therefore, the gap between the outer section 18c of the cylindrical body 18 and the front end 6g of the rotating body 6 will become the amount of L1 that the rotating body advances. Therefore, when the pen pressure is applied, the ballpoint pen refill 8 can be retracted. The length will also reduce the amount of L1. In addition, since the amount of deformation of the elastic member 20 when the pen pressure is applied is also reduced, the pressure applied to the pressurizing space 21 is reduced. As a result, by rotating the rotating body 6 to the left by a portion, the pressure applied to the atom can be made. The pressure at the rear end of the ink 11 in the pen refill 8 decreases.

並且，從第10B圖之狀態使轉動體6更朝從後端側觀看的左方向(逆時計方向)旋轉，使第一凸輪突起6d沿著滑移構件5之第一凸輪斜面5f移動，而設為第10C圖之狀態，從而如第11B圖至第11C圖所示，藉由第一凸輪機構30，轉動體6之第一凸輪突起6d會從第2段部5g2朝相鄰之第3段部5g3移動，且如第12B圖至第12C圖所示，藉由第二凸輪機構40，轉動體6之第二凸輪突起6f會從第2段部22b2移動至相鄰之第3段部22b3。此時，由於將第一凸輪突起之移動量L2與第二凸輪突起之移動量M2設為相同，因此滑動構件22不會移動，僅轉動體6會相對於筒狀體18更前進M2的份量，且轉動體6之前端6g會與筒狀體18之外段部18c抵接。 Further, from the state of FIG. 10B, the rotating body 6 is further rotated in the left direction (counter-clockwise direction) viewed from the rear end side, so that the first cam protrusion 6d moves along the first cam inclined surface 5f of the sliding member 5, and It is set to the state of FIG. 10C, so that as shown in FIGS. 11B to 11C, the first cam protrusion 6d of the rotating body 6 will move from the second stage portion 5g2 to the adjacent third by the first cam mechanism 30. The segment portion 5g3 moves, and as shown in FIGS. 12B to 12C, the second cam projection 6f of the rotating body 6 is moved from the second segment portion 22b2 to the adjacent third segment portion by the second cam mechanism 40. 22b3. At this time, since the movement amount L2 of the first cam protrusion and the movement amount M2 of the second cam protrusion are set to be the same, the sliding member 22 does not move, and only the rotating body 6 advances the amount of M2 relative to the cylindrical body 18 The front end 6g of the rotating body 6 will be in contact with the outer section 18c of the cylindrical body 18.

在此狀態下，筒狀體18會因轉動體6而無法後退， 因此原子筆補充筆芯8亦無法後退，即使在書寫時施加有筆壓，油墨11亦不會被加壓，而可作為非加壓式之筆具使用，並且即使在維持於該狀態之下保管，原子筆補充筆芯8內亦不會被加壓，因此，藉由設為第10C圖之狀態，可防止在保管時油墨11從原子筆尖之前端流出。 In this state, the cylindrical body 18 cannot retreat due to the rotating body 6, Therefore, the ballpoint pen refill 8 cannot be backed up. Even if pen pressure is applied during writing, the ink 11 will not be pressurized, but can be used as a non-pressurized pen, and even if maintained in this state. In storage, the ballpoint pen refill 8 is not pressurized. Therefore, by setting the state as shown in FIG. 10C, the ink 11 can be prevented from flowing out from the front end of the ballpoint pen tip during storage.

此外，雖未詳細說明，但在本實施形態中，藉由在非敲擊時也與敲擊時同樣地使轉動體6轉動，從而可在書寫時變更施加於油墨11之壓力的設定。 In addition, although not described in detail, in this embodiment, the setting of the pressure applied to the ink 11 can be changed during writing by rotating the rotating body 6 in the same manner as during the non-strike.

藉由以上構成，本實施形態之加壓式筆具1係藉由使轉動體6轉動而使加壓力調整機構24作動，以配合使用者之喜好來調整油墨收容筒10內之加壓力，並且，即便使轉動體6轉動來變更施加於油墨11之加壓力的設定，原子筆補充筆芯8亦不會相對於軸筒前後移動，因此原子筆補充筆芯8之前端部從前軸3之前端開口部3a突出的長度不會變化，不用變更把持時之位置即可使用筆具。 With the above configuration, the pressurized pen tool 1 of this embodiment operates the pressure adjusting mechanism 24 by rotating the rotating body 6 to adjust the pressure in the ink container 10 according to the preference of the user, and Even if the rotating body 6 is rotated to change the setting of the pressure applied to the ink 11, the ballpoint pen refill 8 will not move back and forth relative to the shaft cylinder, so the front end of the ballpoint pen refill 8 is from the front end of the front shaft 3. The length of the protruding portion of the opening portion 3a does not change, and the pen can be used without changing the position at the time of holding.

本實施形態之加壓式筆具1係具備：軸筒4，係可將填充有筆具用油墨組成物(油墨)11之補充筆芯8收容在內部；加壓機構7，係隨著補充筆芯8之後退而對筆具用油墨組成物(油墨)11施加壓力；以及加壓力調整機構24，係調整壓力。 The pressurized pen tool 1 according to this embodiment is provided with: a shaft cylinder 4 that can accommodate a refill 8 that is filled with an ink composition (ink) 11 for the pen tool; and a pressurization mechanism 7 that The refill 8 moves backward to apply pressure to the ink composition (ink) 11 for a writing instrument; and a pressure adjustment mechanism 24 is used to adjust the pressure.

依據此種加壓式筆具1，在可隨著藉由書寫時之筆壓而進行之補充筆芯8的後退而對該補充筆芯8內之筆具用油墨組成物(油墨)11施加壓力的加壓式筆具1中，可藉由加壓力調整機構24而調整對筆具用油墨組成物(油 墨)11施加之壓力，使書寫時從補充筆芯8流出的筆具用油墨組成物(油墨)11之流出量變化。藉此，可配合使用者之喜好來調整筆跡之粗度及/或濃度。 According to this pressurized writing instrument 1, the ink composition (ink) 11 for writing instruments in the supplementary refill 8 can be applied as the refill 8 is retreated by the pen pressure during writing. In the pressurized writing instrument 1 under pressure, the ink composition (oil The pressure applied by the ink 11 changes the amount of the ink composition (ink) 11 for writing instruments that flows out of the refill 8 during writing. Thereby, the thickness and / or density of the handwriting can be adjusted according to the preference of the user.

本實施形態之加壓式筆具1係更具備以從軸筒4之後端突出之方式設置之轉動體6，且加壓力調整機構24係藉由使轉動體6轉動來調整壓力。 The pressurized writing instrument 1 of this embodiment further includes a rotating body 6 provided so as to protrude from the rear end of the barrel 4, and the pressure adjusting mechanism 24 adjusts the pressure by rotating the rotating body 6.

依據此種加壓式筆具1，藉由使用者使轉動體6轉動，可容易地調整施加在筆具用油墨組成物(油墨)11之加壓力。 According to this pressurized writing instrument 1, the user can easily adjust the pressing force applied to the ink composition (ink) 11 for writing instruments by rotating the rotor 6.

本實施形態之加壓式筆具1係在軸筒4內收容原子筆補充筆芯8而構成者，該原子筆補充筆芯8係具備：填充有筆具用油墨組成物(油墨)11之油墨收容筒10；及在該油墨收容筒10之前方部的原子筆尖13；且在原子筆補充筆芯8之後方配設有加壓機構7，在藉由施加筆壓使原子筆補充筆芯8後退時，該加壓機構7係對筆具用油墨組成物(油墨)11之後端施加壓力；其中，在加壓機構7之後方具備有：從軸筒4之後端突出之轉動體6；及藉由使該轉動體6轉動而作動，以調整原子筆補充筆芯8之後退量的加壓力調整機構24；加壓機構7係以相對於軸筒4無法轉動但前後移動自如之方式被卡止；轉動體6係以相對於軸筒4轉動自如之方式被卡止；且該加壓式筆具1構成為：藉由使轉動體6轉動而使加壓力調整機構24作動，以調整施加於油墨收容筒10內之筆具用油墨組成物(油墨)11之後端的壓力，並且在使轉動體6轉動之前後，使 軸方向中之原子筆補充筆芯8相對於軸筒4的相對位置不會變化。 The pressurized pen tool 1 according to the present embodiment is configured by accommodating an atomic pen refill 8 in a shaft barrel 4. The ball pen refill 8 is provided with an ink composition (ink) 11 filled with a pen. An ink containing cylinder 10; and an atomic pen tip 13 at the front part of the ink containing cylinder 10; and a pressure mechanism 7 is provided after the atomic pen refill 8 to refill the atomic pen with a pen pressure 8 When retreating, the pressurizing mechanism 7 applies pressure to the rear end of the ink composition (ink) 11 for writing instruments. Among them, after the pressurizing mechanism 7 is provided: a rotating body 6 protruding from the rear end of the shaft cylinder 4; And a pressure adjustment mechanism 24 that is adjusted by rotating the rotating body 6 to adjust the amount of ball pen replenishing the refill 8; the pressure mechanism 7 is moved in a manner that cannot be rotated relative to the shaft cylinder 4 but moves freely back and forth Locking; the rotating body 6 is locked in a freely rotatable manner with respect to the shaft cylinder 4; and the pressure-type pen tool 1 is configured to: by rotating the rotating body 6, the pressure adjusting mechanism 24 is operated to adjust Pressure applied to the rear end of the ink composition (ink) 11 for writing instruments in the ink container 10 And before rotating the rotating body 6, The relative position of the ballpoint pen refill 8 in the axial direction with respect to the shaft cylinder 4 does not change.

依據此種加壓式筆具1，係藉由使轉動體6轉動而令使原子筆補充筆芯8之後退量變化之加壓力調整機構24作動，以調整在書寫時施加在筆具用油墨組成物(油墨)11之後端的壓力，藉此變更從原子筆補充筆芯8之原子筆尖13之前端流出的筆具用油墨組成物(油墨)11之流出量，而可配合使用者之喜好來調整筆跡之粗度、或筆跡濃度。 According to this pressurized writing instrument 1, the pressure adjustment mechanism 24 for changing the amount of the ball pen refilling after the refill 8 is operated by rotating the rotating body 6 to adjust the ink applied to the writing instrument when writing. The pressure at the rear end of the composition (ink) 11 can be used to change the amount of ink composition (ink) 11 for writing utensils flowing out from the front end of the ballpoint pen tip 13 of the ballpoint pen refill 8 to match the user's preference. Adjust the thickness or thickness of the handwriting.

並且，本實施形態之加壓式筆具1係所謂之筆壓加壓式，因此僅在施加筆壓時會對筆具用油墨組成物(油墨)11之後端施加壓力。因此，在非書寫時或保管時不會對筆具用油墨組成物(油墨)11之後端施加壓力，而可防止油墨從原子筆尖13之前端漏出。 In addition, since the pressurized writing instrument 1 of this embodiment is a so-called pen pressure pressurization type, pressure is applied to the rear end of the ink composition (ink) 11 for writing instruments only when the pen pressure is applied. Therefore, no pressure is applied to the rear end of the ink composition (ink) 11 for writing instruments during non-writing or storage, and ink can be prevented from leaking out from the front end of the ballpoint pen tip 13.

再者，在使轉動體6轉動之際，由於構成為使軸方向中之原子筆補充筆芯8與軸筒4之相對位置不會變化，因此原子筆補充筆芯8之前端部從軸筒4之前端開口部3a突出的長度不會變化。因此，即使調整加壓力亦無須改變把持軸筒4之位置，可在將至紙面為止之距離感或把持位置保持為固定之情形下繼續進行書寫。 When the rotating body 6 is rotated, the relative position of the ballpoint pen refill 8 and the barrel 4 in the axial direction is not changed, so the front end of the ballpoint pen refill 8 is removed from the barrel. 4 The length of the front end opening 3a does not change. Therefore, it is not necessary to change the position of the holding shaft 4 even if the pressure is adjusted, and the writing can be continued while the distance to the paper surface or the holding position is fixed.

在本實施形態之加壓式筆具1中，在軸筒4之內部配設有：以相對於該軸筒4無法轉動但前後移動自如之方式被卡止的滑移構件5；滑移構件5係具備：配設在該滑移構件5之內側的加壓機構7；及以其一部分從該 滑移構件5之後端開口部朝後方突出之方式配設的轉動體6；該加壓式筆具1構成為：藉由將轉動體6朝前方推壓，而使原子筆補充筆芯8之前端部從軸筒4之前端開口部3a突出。 In the pressurized writing instrument 1 of the present embodiment, a slide member 5 which is locked in such a manner as to be unable to rotate relative to the shaft cylinder 4 but move freely forward and backward is provided inside the shaft cylinder 4; The 5 series includes: a pressure mechanism 7 disposed inside the sliding member 5; The rotating body 6 provided in such a manner that the rear end opening portion of the sliding member 5 protrudes rearward; the pressure-type pen tool 1 is configured to push the rotating body 6 forward to make the ballpoint pen refill 8 The front end portion protrudes from the front end opening portion 3 a of the shaft cylinder 4.

依據此種加壓式筆具1，可將加壓式筆具1作為以使原子筆補充筆芯8之前端部從軸筒4之前端開口部3a突出的方式構成之所謂之敲擊式的加壓式筆具。 According to such a press-type writing instrument 1, the press-type writing instrument 1 can be a so-called percussion type which is configured so that the front end portion of the ball pen refill 8 protrudes from the front end opening portion 3 a of the barrel 4.

在本實施形態中，係在使轉動體106朝前方敲擊之狀態下使該轉動體106轉動之際，使對位用標記106f之前端頂部106g對合於後軸102之加壓力顯示部102h的線狀部，並讀取位於線狀部之前部的數字，可辨識出此時施加於油墨之後端的加壓力。 In this embodiment, when the rotating body 106 is rotated with the rotating body 106 being struck forward, the front end top 106g of the registration mark 106f is aligned with the pressure display portion 102h of the rear shaft 102. And read the number located on the front of the linear portion, you can identify the pressing force applied to the rear end of the ink at this time.

此外，在本實施形態中，在使對位用標記106f對合於加壓力顯示部102h之「3」時，係將加壓空間(加壓室)121內之加壓調整為最大之狀態(第27A圖)，當對合於「2」時，係調整成施加有低加壓之狀態(第27B圖)，在對合於「1」時，係調整成未施加有加壓之狀態(第27C圖)。 In addition, in this embodiment, when the alignment mark 106f is aligned with "3" of the pressure display unit 102h, the pressure in the pressurizing space (pressurizing chamber) 121 is adjusted to the maximum state ( (Figure 27A), when mating to "2", it is adjusted to a state where low pressure is applied (Figure 27B), and when mating to "1", it is adjusted to a state where no pressure is applied ( Figure 27C).

再者，在轉動體106之後端開口部壓入裝設有由熱塑性彈性體所形成之尾栓125，且在尾栓125之側面朝軸周方向均等地配置複數個沿著軸方向延伸之突狀部，藉此在使轉動體106連同尾栓125旋轉之際難以滑動。 Further, a tail bolt 125 formed of a thermoplastic elastomer is press-fitted into the opening at the rear end of the rotating body 106, and a plurality of protrusions extending in the axial direction are evenly arranged on the side surface of the tail bolt 125 toward the shaft circumferential direction. This makes it difficult to slide the rotating body 106 together with the tail bolt 125.

此外，藉由滑移構件105、轉動體106、尾栓125及活塞118而構成：加壓力調整機構160，可藉由使轉動體106轉動而變更加壓空間121加壓之壓力。 In addition, the sliding member 105, the rotating body 106, the tail bolt 125, and the piston 118 are configured: the pressure adjusting mechanism 160 can change the pressure of the pressurizing space 121 by rotating the rotating body 106.

當從第15圖之狀態使尾栓125及轉動體106抵抗敲 擊用線圈彈簧115之彈壓力朝前方推壓(第15圖之箭頭F方向)時，由於轉動體106之第二凸輪突起106d與活塞118之第二凸輪斜面118d進行凸輪嵌合，因此活塞118會受到轉動體106推壓而與轉動體106一同前進。然而，當轉動體106之前端106e抵接於缸體117之後端117f時，缸體117會前進，當缸體117之前端與氣密閥119之凸緣部119g抵接時，氣密閥119與裝設於氣密閥119之裝設部119c的原子筆補充筆芯108會與缸體117一同前進，且原子筆補充筆芯108之原子筆尖113的前端部會從前軸103之前端開口部103a突出。 When the tail bolt 125 and the rotating body 106 are resistant to knocking from the state of FIG. 15 When the spring pressure of the striking coil spring 115 is pushed forward (in the direction of arrow F in FIG. 15), the second cam protrusion 106d of the rotating body 106 and the second cam inclined surface 118d of the piston 118 are cam-fitted, so the piston 118 It is pushed by the rotating body 106 and advances with the rotating body 106. However, when the front end 106e of the rotating body 106 abuts on the rear end 117f of the cylinder 117, the cylinder 117 advances. When the front end of the rotating body 106 abuts on the flange portion 119g of the airtight valve 119, the airtight valve 119 A ballpoint pen refill 108 installed with the mounting portion 119c of the airtight valve 119 will advance with the cylinder 117, and a front end portion of the ballpoint pen tip 113 of the ballpoint pen refill 108 will open from the front end of the front shaft 103 103a stands out.

此時，缸體117之卡止突起117b係以前後移動自如之方式與滑移構件105之開縫卡止部105d鬆嵌合，因此前進後的缸體117之卡止突起117b會抵接於開縫卡止部105d之前端，從而滑移構件105會開始前進，滑移構件105之卡掛部105a會卡掛在配置於後軸102之側面的夾具109之前端部的被卡掛部109c，藉此成為使原子筆補充筆芯108之原子筆尖113的前端維持從前軸103(軸筒104)之前端開口部103a突出之狀態的第20圖之狀態。 At this time, the locking protrusion 117b of the cylinder 117 is loosely fitted to the slit locking portion 105d of the sliding member 105 in a forward and backward manner, so that the locking protrusion 117b of the cylinder 117 after the forward movement will abut against The front end of the slit-locking portion 105d causes the sliding member 105 to start advancing, and the hooking portion 105a of the sliding member 105 is hooked to the hooked portion 109c at the front end of the clamp 109 disposed on the side of the rear shaft 102. As a result, the state of FIG. 20 is maintained in which the tip of the ballpoint pen tip 113 of the ballpoint pen refill 108 maintains a state protruding from the front end opening 103a of the front shaft 103 (shaft cylinder 104).

在此，當推壓夾具109之後端部(第20圖之箭頭G方向)，並解除卡掛於夾具109之被卡掛部109c的滑移構件105之卡掛部105a的卡掛狀態時，藉由敲擊用線圈彈簧115之彈壓力，原子筆補充筆芯108、加壓機構130、墊圈114、滑移構件105及轉動體106會朝後方移動而回到第15圖之狀態。 Here, when the rear end portion of the jig 109 is pressed (in the direction of arrow G in FIG. 20) and the hooking state of the hooking portion 105 a of the sliding member 105 which is hooked on the hooked portion 109 c of the jig 109 is released, By the spring pressure of the coil spring 115 for striking, the ballpoint pen refill 108, the pressurizing mechanism 130, the washer 114, the sliding member 105, and the rotating body 106 move backward and return to the state of FIG. 15.

接著，說明在本實施形態中，利用書寫時之書寫壓，透過油墨追隨體112將壓力施加在原子筆補充筆芯108內之油墨111之後端的狀態。 Next, in this embodiment, the state of the rear end of the ink 111 in the ballpoint pen refill 108 is applied through the ink follower 112 using the writing pressure at the time of writing.

在第20圖及第23圖之原子筆尖113的前端從前軸103之前端開口部103a突出的狀態下，當如第21圖所示使軸筒104傾斜並保持，並對原子筆尖113之前端施加筆壓而使原子筆補充筆芯108朝第21圖之箭頭H方向後退時，滑移構件105由於卡掛部105a卡掛於夾具109之被卡掛部109c而無法後退，轉動體106由於相對於滑移構件105進行凸輪嵌合而無法後退，並且，活塞118由於與轉動體106進行凸輪嵌合而無法後退，因此氣密閥119會抵抗加壓用線圈彈簧120之彈壓力而與原子筆補充筆芯108一同後退。再者，當固定在氣密閥119之第二O環123抵接於缸體117之抵接部117g(側孔117c之後端)時，會成為使加壓空間(加壓室)121與外部連通之空氣通路124會被關閉且加壓空間121內被氣密的第24圖之狀態。再者，當原子筆補充筆芯108後退時，缸體117會與氣密閥119一同相對於活塞118後退，加壓空間121之容積會減小，藉此成為該加壓空間121內被壓縮，透過油墨追隨體112而經由氣密閥119之內孔119a而對原子筆補充筆芯108內之油墨111的後端施加壓力之第22圖及第25圖之狀態。 In a state where the tip of the ballpoint pen tip 113 in FIGS. 20 and 23 protrudes from the front end opening 103a of the front shaft 103, when the shaft cylinder 104 is tilted and held as shown in FIG. 21, the front end of the ballpoint pen tip 113 is applied. When the pen refill 108 is retracted in the direction of arrow H in FIG. 21 by applying pen pressure, the sliding member 105 cannot retreat because the hooking portion 105a is hooked to the hooked portion 109c of the clamp 109, and the rotating body 106 The cam fitting of the sliding member 105 cannot retreat, and the piston 118 cannot retreat due to the cam fitting of the rotating body 106. Therefore, the airtight valve 119 resists the spring pressure of the coil spring 120 for pressure and contacts the ballpoint pen. The refill 108 retreats together. Furthermore, when the second O-ring 123 fixed to the airtight valve 119 abuts on the abutting portion 117g (the rear end of the side hole 117c) of the cylinder 117, the pressurizing space (pressurizing chamber) 121 and the outside The communicating air passage 124 is closed, and the state of FIG. 24 is airtight in the pressurized space 121. In addition, when the ballpoint pen refill 108 is retracted, the cylinder 117 and the airtight valve 119 are retracted relative to the piston 118, and the volume of the pressurized space 121 is reduced, thereby becoming compressed in the pressurized space 121. 22 and 25 through the ink follower 112 and the inner end 119a of the airtight valve 119 to apply pressure to the rear end of the ink 111 in the ballpoint pen refill 108.

在此，從第22圖及第25圖之狀態解除施加於原子筆尖113之前端的筆壓時，氣密閥119會利用加壓用線圈彈簧120的彈壓力而前進。此時，藉由筆壓將第 二O環123推壓至缸體117之抵接部117g(側孔117c之後端)並使之變形，從而第二O環123與缸體117會成為較輕之嵌合狀態。因此，會配合氣密閥119之前進而將缸體117朝前方拉動，缸體117亦同時欲往前進。然而，由於將藉由第一O環122而作用在活塞118與缸體117之間的嵌合力設定成比藉由第二O環123而作用在氣密閥119與缸體117之間的嵌合力更大，因此缸體117係不會相對於活塞118移動，而成為僅氣密閥119先前進之第26圖的狀態。藉此，當第二O環123與缸體117之抵接部117g(側孔117c之後端)分離時，會形成空氣通路124而使加壓空間121與外部相連通而成為與大氣壓同壓。然後，由於前進後之氣密閥119的外側突起119d之前端與缸體117之側孔117c的前端相抵接，因此缸體117亦會延遲地開始前進，而回到第20圖及第23圖之狀態。結果，藉由利用已施加筆壓之狀態的加壓式筆具101進行書寫，油墨收容筒110內之油墨111會被消耗，即使加壓空間121相應地被減壓，仍會在解除筆壓時因氣密閥119於缸體117前進之前前進而藉此形成空氣通路124，使加壓空間121成為與大氣同壓，因此加壓空間121內係不會受到與藉由筆壓而壓縮時同等之強制性減壓，而可防止成為比大氣壓更低之負壓狀態。 Here, when the pen pressure applied to the front end of the ballpoint pen tip 113 is released from the states of FIGS. 22 and 25, the airtight valve 119 advances by the spring pressure of the coil spring 120 for pressurization. At this time, the first The second O-ring 123 is pressed to the abutting portion 117g (the rear end of the side hole 117c) of the cylinder 117 and deformed, so that the second O-ring 123 and the cylinder 117 will be fitted into a lighter state. Therefore, the cylinder block 117 is pulled forwards in cooperation with the air-tight valve 119, and the cylinder block 117 also wants to move forward at the same time. However, the fitting force acting between the piston 118 and the cylinder 117 by the first O-ring 122 is set to be larger than the fitting force acting between the air-tight valve 119 and the cylinder 117 by the second O-ring 123. The total force is larger, so the cylinder 117 does not move relative to the piston 118, and only the airtight valve 119 advances to the state shown in FIG. 26. Thereby, when the second O-ring 123 is separated from the abutting portion 117g (the rear end of the side hole 117c) of the cylinder 117, an air passage 124 is formed to communicate the pressurizing space 121 with the outside and become the same pressure as the atmospheric pressure. Then, since the front end of the outer protrusion 119d of the forwardly sealed airtight valve 119 is in contact with the front end of the side hole 117c of the cylinder block 117, the cylinder block 117 also starts to advance with a delay, and returns to FIGS. 20 and 23 Of the state. As a result, by writing using the pressurized pen 101 in a state where pen pressure is applied, the ink 111 in the ink containing cylinder 110 is consumed, and even if the pressurizing space 121 is decompressed accordingly, the pen pressure is still being released. At this time, the air-tight valve 119 moves forward before the cylinder 117 advances, thereby forming an air passage 124, so that the pressurized space 121 is at the same pressure as the atmosphere. Therefore, the interior of the pressurized space 121 is not compressed by the pressure of the pen. Equivalent forced decompression can prevent a negative pressure state lower than atmospheric pressure.

此外，就一例而言，構成為：在對本實施形態之原子筆尖113的前端施加筆壓的第22圖及第25圖之狀態下，藉由第二O環123而在氣密閥119與缸體117 之間產生的嵌合力(使缸體117相對於氣密閥119移動所需之推壓力)係為0.1N，藉由第一O環122而產生在活塞118與缸體117之間的嵌合力(使缸體117相對於活塞118移動所需之推壓力)係為0.5N，因此在解除筆壓之際，缸體117係不會相對於活塞118移動，僅氣密閥119先前進。 In addition, as an example, it is configured such that, in a state of FIGS. 22 and 25 in which a pen pressure is applied to the tip of the atomic pen tip 113 of this embodiment, a second O-ring 123 is used to connect the airtight valve 119 and the cylinder. Body117 The fitting force (the pushing force required to move the cylinder block 117 relative to the airtight valve 119) between them is 0.1N, and the fitting force between the piston 118 and the cylinder block 117 is generated by the first O ring 122. (The pushing force required to move the cylinder 117 relative to the piston 118) is 0.5N. Therefore, when the pen pressure is released, the cylinder 117 does not move relative to the piston 118, and only the airtight valve 119 advances.

接著，說明在第20圖之敲擊狀態下，藉由使轉動體106相對於後軸102轉動而使加壓力調整機構160作動，以調整對油墨111施加之加壓力的動作。 Next, a description will be given of an operation of adjusting the pressure applied to the ink 111 by rotating the rotating body 106 relative to the rear shaft 102 in the striking state of FIG. 20 to operate the pressure adjusting mechanism 160.

當從第20圖及第27A圖之狀態使轉動體106朝從後端側觀看的左方向(逆時針方向)旋轉，直到轉動體106之對位用標記106f的前端頂部106g(參照第14圖)從後軸102之加壓力顯示部102h之「3」對位至「2」之位置為止，而成為第27B圖之狀態時，滑移構件105以相對於後軸102無法轉動之方式被卡止，因此如第28A圖至第28B圖所示，轉動體106之第一凸輪突起106b係沿著滑移構件105之第一凸輪斜面105e從第1段部105f1朝相鄰之第2段部105f2移動。此時，轉動體106係相對於滑移構件105前進第一凸輪突起106b移動一段所成之L1的份量(參照第28A圖)。 When the rotating body 106 is rotated in the left direction (counterclockwise) as viewed from the rear end side from the state of FIGS. 20 and 27A, it reaches the top 106g of the front end of the positioning mark 106f (see FIG. 14). ) From the "3" position to the "2" position of the pressure display portion 102h of the rear axle 102, when the state shown in Fig. 27B is reached, the sliding member 105 is locked in such a manner that it cannot rotate relative to the rear axle 102. Therefore, as shown in FIGS. 28A to 28B, the first cam protrusion 106b of the rotating body 106 follows the first cam inclined surface 105e of the sliding member 105 from the first section 105f1 to the adjacent second section 105f2 moves. At this time, the rotating body 106 is a portion of L1 formed by moving the first cam protrusion 106b forward with respect to the sliding member 105 (refer to FIG. 28A).

再者，活塞118係透過缸體117及滑移構件105而以相對於後軸102(軸筒104)無法轉動之方式被卡止，因此如第29A圖至第29B圖所示，伴隨轉動體106之旋轉，轉動體106之第二凸輪突起106d係沿著活塞118之第二凸輪斜面118d從第1段部118e1移動至相鄰之第2段部118e2。此時，活塞118係相對於轉動體106後退第二凸輪突起 106d移動一段所成之M1的份量(參照第29A圖)。因此，活塞118係藉由第一凸輪機構140而前進L1的份量，且藉由第二凸輪機構150而後退M1的份量。並且，在本實施形態中，由於構成為L1=M1，因此僅轉動體106相對於軸筒104前進L1的份量，活塞118之相對位置係不會相對於軸筒104變化。並且，由於活塞118之位置不會變化，因此藉由加壓用線圈彈簧120而朝前方被彈壓的氣密閥119之位置亦不會變化，裝設在氣密閥119之裝設部119c的原子筆補充筆芯108相對於軸筒104的相對位置亦不會變化。因此，缸體117之後端117f與轉動體106之前端106e的間隙會變為短少轉動體106所前進之L1的份量，因此在施加筆壓之際，原子筆補充筆芯108可後退之長度亦會減少L1的份量，且加壓空間(加壓室)121之壓縮量會減少，因此施加在加壓空間121內之壓力會下降。結果，藉由使轉動體106朝從後端側觀看的左方向(逆時針方向)旋轉一段份，可使施加在原子筆補充筆芯108內之油墨111之後端的壓力下降。 The piston 118 is locked through the cylinder 117 and the sliding member 105 so as to be unable to rotate relative to the rear shaft 102 (shaft cylinder 104). Therefore, as shown in FIGS. 29A to 29B, the piston 118 is accompanied by the rotating body. The rotation of 106 causes the second cam protrusion 106d of the rotating body 106 to move from the first stage portion 118e1 to the adjacent second stage portion 118e2 along the second cam inclined surface 118d of the piston 118. At this time, the piston 118 is retracted with respect to the rotating body 106 by the second cam protrusion. 106d moves a portion of M1 (refer to FIG. 29A). Therefore, the piston 118 advances the weight of L1 by the first cam mechanism 140, and retreats the weight of M1 by the second cam mechanism 150. Further, in this embodiment, since the configuration is L1 = M1, only the amount by which the rotating body 106 advances L1 with respect to the shaft cylinder 104, and the relative position of the piston 118 does not change with respect to the shaft cylinder 104. In addition, since the position of the piston 118 does not change, the position of the airtight valve 119 that is urged forward by the coil spring 120 for pressure does not change. The relative position of the ballpoint pen refill 108 relative to the shaft cylinder 104 will not change. Therefore, the gap between the rear end 117f of the cylinder body 117 and the front end 106e of the rotating body 106 will become the amount of L1 that the rotating body 106 advances. Therefore, when the pen pressure is applied, the ball pen refills the refillable length of the refill 108. Since the amount of L1 is reduced and the compression amount of the pressurizing space (pressurizing chamber) 121 is reduced, the pressure applied in the pressurizing space 121 is reduced. As a result, by rotating the rotating body 106 in the left direction (counterclockwise) viewed from the rear end side, the pressure applied to the rear end of the ink 111 in the ballpoint pen refill 108 can be reduced.

並且，從第27B圖之狀態使轉動體106朝左方向(逆時針方向)旋轉，直到轉動體106之對位用標記106f的前端頂部106g(參照第14圖)從後軸102之加壓力顯示部102h之「2」對位至「1」之位置為止，使第一凸輪突起106b沿著滑移構件105之第一凸輪斜面105e移動而成為第27C圖之狀態，從而如第28B圖至第28C圖所示，藉由第一凸輪機構140，轉動體106之第一凸輪突起106b 係從第2段部105f2朝相鄰之第3段部105f3移動，且如第29B圖至第29C圖所示，藉由第二凸輪機構150，轉動體106之第二凸輪突起106d係從第2段部118e2移動至相鄰之第3段部118e3。此時，由於使第一凸輪突起106b之移動量L2與第二凸輪突起106d之移動量M2相同，因此活塞118係不會移動，僅轉動體106會相對於缸體117更前進M2的份量，且轉動體106之前端106e會與活塞118之外表面段部118c抵接。 Then, from the state shown in FIG. 27B, the rotating body 106 is rotated to the left (counterclockwise) until the top 106g (see FIG. 14) of the front end of the alignment mark 106f of the rotating body 106 is displayed from the pressure of the rear shaft 102. Position "2" of the portion 102h to the position of "1", and move the first cam protrusion 106b along the first cam inclined surface 105e of the sliding member 105 to the state shown in FIG. 27C, so as to be shown in FIGS. 28B to 28 As shown in FIG. 28C, by the first cam mechanism 140, the first cam protrusion 106b of the rotating body 106 It moves from the second stage portion 105f2 to the adjacent third stage portion 105f3, and as shown in FIGS. 29B to 29C, the second cam protrusion 106d of the rotating body 106 is moved from the first portion by the second cam mechanism 150. The second-stage part 118e2 moves to the adjacent third-stage part 118e3. At this time, since the movement amount L2 of the first cam protrusion 106b and the movement amount M2 of the second cam protrusion 106d are made the same, the piston 118 does not move, and only the rotating body 106 advances the amount of M2 relative to the cylinder 117. In addition, the front end 106e of the rotating body 106 is in contact with the outer surface section 118c of the piston 118.

在該狀態下，由於缸體117之後端117f會抵接於轉動體106之前端106e而無法後退，因此原子筆補充筆芯108後退之長度亦會減少，而無法將加壓空間121予以密閉。因此，即使在書寫時施加筆壓，油墨111亦不會藉由加壓機構130而被加壓，而可作為非加壓式之筆具使用，即使在敲擊之狀態下進行保管亦不會由於誤動作而使原子筆補充筆芯108內被加壓，因此可防止在保管時油墨111從原子筆尖113之前端流出。 In this state, since the rear end 117f of the cylinder body 117 abuts on the front end 106e of the rotating body 106 and cannot retreat, the retreat length of the ballpoint pen refill 108 also decreases, and the pressurizing space 121 cannot be closed. Therefore, even if pen pressure is applied when writing, the ink 111 will not be pressurized by the pressurizing mechanism 130, but can be used as a non-pressurized pen, even if it is stored under a percussion state. The ball pen refill 108 is pressurized due to a malfunction, so that the ink 111 can be prevented from flowing out from the front end of the ball pen tip 113 during storage.

此外，雖未詳細說明，但在本實施形態中，藉由在非敲擊時也與敲擊時同樣地使轉動體106轉動，從而可在書寫時變更施加於油墨111之壓力的設定。 In addition, although not described in detail, in the present embodiment, the setting of the pressure applied to the ink 111 can be changed during writing by rotating the rotating body 106 in the same manner as during the non-strike.

此外，在本實施形態中，就一例而言，在使轉動體106之對位用標記106f對合於後軸102之加壓力顯示部102h之「3」的位置之狀態下施加筆壓而使加壓機構130作動時的加壓空間121內之加壓狀態，係在將大氣壓設為1000hpa時為1040hpa，在使對位用標記106f對合 於加壓力顯示部102h之「2」的狀態下為1020hpa，在使對位用標記106f對合於「1」之位置的狀態下，由於係無加壓，因此為與大氣壓同壓的1000hpa。 In addition, in this embodiment, as an example, a pen pressure is applied in a state in which the alignment mark 106f of the rotating body 106 is aligned with the position “3” of the pressure display portion 102h of the rear shaft 102. The pressure state in the pressure space 121 when the pressure mechanism 130 operates is 1040 hpa when the atmospheric pressure is set to 1000 hpa, and the alignment mark 106f is aligned It is 1020 hpa in the state of "2" of the pressurizing display portion 102h, and in a state where the alignment mark 106f is aligned with the position of "1", there is no pressurization, so it is 1000 hpa at the same pressure as the atmospheric pressure.

藉由以上構成，本實施形態之加壓式筆具101係藉由使轉動體106轉動並使加壓力調整機構160作動，從而配合使用者之喜好來調整油墨收容筒110內之加壓力，變更從原子筆尖113之前端送出之油墨量而可提升筆跡之粗度或筆跡濃度，並且，即便使轉動體106轉動而變更對油墨111施加之加壓力的設定，原子筆補充筆芯108亦不會相對於軸筒前後移動，因此原子筆補充筆芯108之前端部從前軸103之前端開口部103a突出的長度並不會變化，不用變更把持之位置即可繼續使用筆具。並且，可提供一種在筆壓解除時使加壓空間121(加壓室)內成為負壓而可防止油墨收容筒110內之油墨111之逆流的加壓式筆具。 With the above configuration, the pressure pen 101 of this embodiment is configured to adjust the pressure in the ink container 110 by changing the rotation body 106 and actuating the pressure adjustment mechanism 160 to change the pressure in the ink container 110 according to the user's preference. The amount of ink sent from the front end of the ballpoint pen 113 can increase the thickness or thickness of the handwriting. Even if the rotating body 106 is rotated to change the setting of the pressure applied to the ink 111, the ballpoint pen refill 108 will not Relative to the shaft movement, the length of the front end of the ballpoint pen refill 108 protruding from the front end opening 103a of the front shaft 103 does not change, and the pen can be used without changing the holding position. In addition, it is possible to provide a pressurized writing instrument that makes the pressure in the pressurizing space 121 (pressurizing chamber) a negative pressure when the pen pressure is released and prevents the backflow of the ink 111 in the ink containing cylinder 110.

本實施形態之加壓式筆具101係在軸筒104內收容原子筆補充筆芯108而構成者，該原子筆補充筆芯108係具備：填充有筆具用油墨組成物(油墨)111之油墨收容筒110；及在該油墨收容筒110之前方部的原子筆尖113；且在原子筆補充筆芯108之後方配設有加壓機構130，在藉由施加筆壓使原子筆補充筆芯108後退時，該加壓機構130係對筆具用油墨組成物111之後端施加壓力；其中，該加壓機構130係具備有：缸體117，係形成為筒状；氣密閥119，係在外周面具有氣密用變形部(第二O環)123，且以相對於缸體117前後移動自如之方式形成；活塞118， 係以前後移動自如之方式装設在缸體11之後部內孔117d；氣密構件(第一O環)122，係配設在活塞118與缸體117之間；加壓室(加壓空間)121，係由缸體117、氣密閥119、活塞118、及氣密構件(第一O環)122所包圍，且連通至原子筆補充筆芯108之後部；彈壓構件(加壓用線圈彈簧)120，係配設在氣密閥119與活塞118之間，且使氣密閥119朝前方彈壓；當對原子筆尖113之前端施加有筆壓時，原子筆補充筆芯108會後退，與該原子筆補充筆芯108之後退相連動，缸體117及氣密閥119會抵抗彈壓構件(加壓用線圈彈簧)120之彈壓力而相對於活塞118而後退，在使加壓室(加壓空間)121內密閉之後使之壓縮並進行加壓，當解除對原子筆補充筆芯108施加之筆壓時，氣密閥119會比缸體117先相對於活塞118前進，藉此形成使加壓室(加壓空間)121與外部相連通之空氣通路124，並解除加壓室(加壓空間)121之氣密状態，而成為與大氣壓同壓，然後缸體117會延遲地前進。 The pressurized writing instrument 101 of the present embodiment is formed by accommodating an atomic pen refill 108 in a shaft barrel 104. The atomic pen refill 108 is provided with an ink composition (ink) 111 filled with a writing instrument. An ink containing cylinder 110; and an atomic pen tip 113 at the front part of the ink containing cylinder 110; and a pressure mechanism 130 is provided after the pen refill 108, and the ball pen is replenished by applying a pen pressure When 108 is retracted, the pressurizing mechanism 130 applies pressure to the rear end of the ink composition 111 for writing instruments. Among them, the pressurizing mechanism 130 is provided with: a cylinder 117, which is formed into a cylindrical shape; an airtight valve 119, which The air-tight deformation part (second O-ring) 123 is formed on the outer peripheral surface, and is formed to move freely forward and backward with respect to the cylinder 117; the piston 118, It is installed in the inner hole 117d at the rear of the cylinder block 11 in a freely moving way; the airtight member (the first O-ring) 122 is arranged between the piston 118 and the cylinder block 117; the pressurizing chamber (pressurizing space) 121 is surrounded by a cylinder 117, an air-tight valve 119, a piston 118, and an air-tight member (the first O-ring) 122, and communicates with the rear of the ball pen refill 108; an elastic member (a coil spring for pressure ) 120, is arranged between the airtight valve 119 and the piston 118, and the airtight valve 119 is spring-pressed forward; when a pen pressure is applied to the front end of the atomic pen tip 113, the ballpoint pen refill 108 will retreat, and When the ball pen is replenished after refilling the refill 108, the cylinder 117 and the airtight valve 119 will withdraw against the spring pressure of the spring member (coil spring for pressurization) 120 and retract relative to the piston 118. (Pressure space) 121 is sealed and compressed and pressurized. When the pen pressure applied to the ball pen refill 108 is released, the airtight valve 119 advances relative to the piston 118 before the cylinder 117, thereby forming an actuator. The air passage 124 that the pressure chamber (pressurized space) 121 communicates with the outside, and releases the airtightness of the pressure chamber (pressurized space) 121 State, and it becomes the same atmospheric pressure, and then the cylinder 117 will move forward delay.

此種加壓式筆具101係構成為：當對原子筆補充筆芯108之前端施加筆壓時，缸體117與氣密閥119會抵抗彈壓構件(加壓用線圈彈簧)120之彈壓力而相對於活塞118後退，且使加壓室(加壓空間)121內密閉、壓縮而加壓，當解除對原子筆補充筆芯108施加之筆壓時，氣密閥119會比缸體117先相對於活塞118前進，藉此形成使加壓室(加壓空間)121與外部相連通之空氣通路124。因此，即使因進行書寫而消耗油墨收容筒110內之筆具用油墨而 使加壓室(加壓空間)121內之壓力下降，仍會在解除加壓室(加壓空間)121之氣密狀態之後使氣密閥119與缸體117、活塞118之相對位置回到施加筆壓之前的狀態，因此可防止加壓室(加壓空間)121內成為氣壓比大氣壓更低的負壓狀態，且可防止因從原子筆尖113前端捲入空氣所造成之油墨的逆流。 This pressurized pen 101 is configured such that when a pen pressure is applied to the front end of the ballpoint pen refill 108, the cylinder 117 and the airtight valve 119 resist the spring pressure of the spring member (coil spring for pressure) 120. In contrast to the piston 118, the pressure chamber (pressurizing space) 121 is closed, compressed, and pressurized. When the pen pressure applied to the pen refill 108 is released, the airtight valve 119 will be lower than the cylinder 117. First, it advances with respect to the piston 118, thereby forming an air passage 124 that communicates the pressurizing chamber (pressurizing space) 121 with the outside. Therefore, even if ink for writing instruments in the ink container 110 is consumed for writing, If the pressure in the pressurizing chamber (pressurizing space) 121 is lowered, the relative position of the airtight valve 119, the cylinder block 117, and the piston 118 will be returned after the airtight state of the pressurizing chamber (pressurizing space) 121 is released. The state before the pen pressure is applied can prevent the negative pressure state in the pressurizing chamber (pressurizing space) 121 from being lower than the atmospheric pressure, and prevent the ink from flowing back due to the air drawn in from the tip of the ballpoint pen 113.

本實施形態之加壓式筆具101係構成為：在對原子筆補充筆芯108之前端施加有筆壓之際，藉由使氣密閥119之氣密用變形部(第二O環)123與缸體117之抵接部相抵接，藉此使加壓室(加壓空間)121內成為氣密狀態；並且構成為：在解除對原子筆補充筆芯108施加之筆壓之際，使藉由氣密構件(第一O環)122而產生在活塞118與缸體117之間的嵌合力比藉由氣密閥119之氣密用變形部(第二O環)123而產生在該氣密閥119與缸體117之抵接部之間的嵌合力更大，藉此使氣密閥119比缸體117先相對於活塞118前進。 The pressurized writing instrument 101 of this embodiment is configured such that, when a pen pressure is applied to the front end of the ballpoint pen refill 108, the airtight deformation part (the second O-ring) of the airtight valve 119 is applied. 123 is in contact with the abutting portion of the cylinder 117, thereby making the pressure chamber (pressurizing space) 121 air-tight; and is configured to release the pen pressure applied to the ballpoint pen refill 108, The fitting force generated between the piston 118 and the cylinder 117 by the air-tight member (first O-ring) 122 is generated at a ratio of the fitting force generated by the air-tight deformation portion (second O-ring) 123 of the air-tight valve 119. The fitting force between the airtight valve 119 and the abutting portion of the cylinder 117 is larger, so that the airtight valve 119 is advanced relative to the piston 118 before the cylinder 117.

在此種加壓式筆具101中，在施加有筆壓之際被氣密閥119推壓而同時地後退之缸體117，係在解除筆壓之際因藉由氣密構件(第一O環)122而產生在與活塞118之間的嵌合力而跟不上氣密閥119之前進，使得氣密閥119之氣密用變形部(第二O環)123與缸體117之前部內端部的抵接狀態被解除而分離，而在氣密用變形部(第二O環)123與前部內端部之間形成與外部相連通之空氣通路124，從而在解除筆壓時可在缸體117前進之前先解除 加壓室(加壓空間)121內之氣密狀態。 In this type of pressurized writing instrument 101, the cylinder 117 that is pushed back by the airtight valve 119 while being pressed when pen pressure is applied is caused by the airtight member (first O-ring) 122, and the fitting force between the piston 118 and the front of the air-tight valve 119 cannot be advanced, so that the air-tight deformation part (second O-ring) 123 of the air-tight valve 119 and the front part of the cylinder 117 The contact state of the end portion is released and separated, and an air passage 124 communicating with the outside is formed between the airtight deformation portion (second O-ring) 123 and the inner end portion of the front portion, so that when the pen pressure is released, the The cylinder 117 is released before proceeding The airtight state in the pressurizing chamber (pressurizing space) 121.

此外，在本實施形態中，於解除筆壓之際藉由氣密用變形部(第二O環)123而產生在氣密閥119與缸體117之前部內端部之間的嵌合力、及藉由氣密構件(第一O環)122而產生在活塞118與缸體117之間的嵌合力，係指使缸體117相對於氣密構件(第一O環)122滑動所需之推壓力、及使缸體117相對於活塞118滑動所需之推壓力，各個嵌合力係可藉由採用推拉計而進行測量。 In addition, in the present embodiment, the fitting force between the airtight valve 119 and the inner end of the front portion of the cylinder 117 is generated by the airtight deformation portion (second O-ring) 123 when the pen pressure is released, and The fitting force generated between the piston 118 and the cylinder block 117 by the airtight member (the first O ring) 122 refers to the pushing force required to slide the cylinder block 117 relative to the airtight member (the first O ring) 122 And the pushing force required to slide the cylinder 117 relative to the piston 118, each fitting force can be measured by using a push-pull meter.

再者，本實施形態之氣密閥119之氣密用變形部(第二O環)123亦可在氣密閥119之側面利用2色成形等而一體地形成，亦可藉由卡止具有橡膠彈性之O環等其他零件而形成。此外，就構成氣密用變形部(第二O環)123之材料而言，可採用具有聚矽氧橡膠、腈橡膠、乙烯-丙烯-二烯橡膠、氟樹脂、熱塑性彈性體等之具有橡膠彈性的合成樹脂，就利用JIS-K6235所測定之硬度計A硬度而言，其硬度係較佳為以20以上90以下形成，以在O環與缸體117之前部內端部抵接之際容易使加壓室(加壓空間)121內成為氣密狀態。 In addition, the airtight deformation part (second O-ring) 123 of the airtight valve 119 of this embodiment may be integrally formed on the side of the airtight valve 119 by two-color molding or the like. Rubber elastic O-ring and other parts. In addition, as the material constituting the airtight deformed portion (second O ring) 123, a rubber having a silicone rubber, a nitrile rubber, an ethylene-propylene-diene rubber, a fluororesin, a thermoplastic elastomer, or the like can be used. The elastic synthetic resin has a hardness of 20 or more and 90 or less in terms of the hardness of the durometer A measured by JIS-K6235, so that it is easy to contact the O-ring with the inner end of the front part of the cylinder 117. The inside of the pressurizing chamber (pressurizing space) 121 is made airtight.

再者，配設在缸體117與活塞118之間的氣密構件(第一O環)122係較佳為將缸體117與活塞118之間予以密封而形成氣密狀態，並且為了在缸體117與活塞118之間產生適度之摩擦力而固定在缸體117或活塞118之任一方，當考慮組裝之容易性時，較佳為卡止在活塞118之外周部。此外，與氣密閥119之氣密用變形部(第二O環)123 同樣地，氣密構件(第一O環)122亦可藉由2色成形等一體地形成在活塞118之外表面或缸體117之內表面。 In addition, the airtight member (first O-ring) 122 disposed between the cylinder 117 and the piston 118 is preferably formed to seal the space between the cylinder 117 and the piston 118 to form an airtight state, and to seal the cylinder A moderate frictional force is generated between the body 117 and the piston 118 and is fixed to either the cylinder 117 or the piston 118. When the ease of assembly is considered, it is preferably locked at the outer periphery of the piston 118. In addition, the airtight deformation section (second O ring) 123 with the airtight valve 119 Similarly, the airtight member (the first O-ring) 122 may be integrally formed on the outer surface of the piston 118 or the inner surface of the cylinder 117 by two-color molding or the like.

並且，就構成氣密構件(第一O環)122之材料而言，可採用聚矽氧橡膠、腈橡膠、乙烯-丙烯-二烯橡膠、氟樹脂、熱塑性彈性體等之具有橡膠彈性的合成樹脂，就利用JIS-K6235所測定之硬度計A硬度而言，其硬度係較佳為以20以上70以下形成。 In addition, as for the material constituting the airtight member (the first O-ring) 122, synthetic materials having rubber elasticity such as silicone rubber, nitrile rubber, ethylene-propylene-diene rubber, fluororesin, and thermoplastic elastomer can be used. The hardness of the resin is preferably from 20 to 70 in terms of hardness A measured by JIS-K6235.

本實施形態之加壓式筆具101係可藉由使與收容在油墨收容筒110之筆具用油墨之後端相接之被密閉的加壓室(加壓空間)121之空氣加壓為比大氣壓更高之氣壓，而可容易地吐出筆具用油墨，其加壓之程度係可依據筆具用油墨之黏度等特性或原子筆尖113之構造而適當地設定。 The pressurized writing instrument 101 of this embodiment can be compressed by the air pressure of the sealed pressurizing chamber (pressurizing space) 121 which is in contact with the rear end of the writing ink contained in the ink containing cylinder 110. The atmospheric pressure is higher and the ink for writing instruments can be easily ejected. The degree of pressure can be appropriately set according to the characteristics of the ink for writing instruments and the structure of the atomic pen tip 113.

此外，將大氣壓設為1000hPa時，在例如黏度低之筆具用油墨(就一例而言為20℃之環境下的黏度為1mPa．s至2000mPa．s之筆具用油墨)中，可藉由將加壓室(加壓空間)121內之被密閉之空氣的氣壓設為超越1005hPa而成為1500hPa之範圍的加壓狀態，而容易地吐出筆具用油墨。 In addition, when the atmospheric pressure is set to 1000 hPa, for example, inks for writing instruments having a low viscosity (for example, inks for writing instruments having a viscosity of 1 mPa · s to 2000 mPa · s under an environment of 20 ° C.) can be used. The pressure of the sealed air in the pressurizing chamber (pressurizing space) 121 is set to a pressurized state in the range of 1500 hPa beyond 1005 hPa, and the ink for writing instruments is easily discharged.

此外，加壓式筆具1、100、101不用限定於油性油墨、水性油墨等油墨種類即可實施。特別是，在使用水性油墨或剪率降黏度性之水性油墨時，因加壓所造成之油墨吐出量的增減會變大，且筆跡之粗度、寬度或筆跡之濃淡等因加壓力之變化所造成之差也較大，因此可適當地使用。再者，在採用使用微膠囊顏料之熱變色性油墨 作為油墨時，由於一般而言筆跡容易變薄，因而希望提高油墨吐出量，然而當油墨吐出量變高時，由於對書寫距離之影響亦較大，因此可適當地使用可配合用途而變更加壓力之本發明。 In addition, the pressure-type writing instruments 1, 100, and 101 can be implemented without being limited to ink types such as oil-based inks and water-based inks. In particular, when using water-based inks or shear-reduced viscosity-reduced water-based inks, the increase or decrease in the amount of ink discharged due to pressure will increase, and the thickness, width, or lightness of the handwriting will increase due to pressure. The difference caused by the change is also large, so it can be used appropriately. Furthermore, thermochromic inks using microcapsule pigments are being used. As an ink, generally, handwriting tends to be thinner, so it is desirable to increase the amount of ink ejected. However, when the amount of ink ejected becomes high, the effect on the writing distance is also large, so it can be used appropriately and can be more pressured according to the application. This invention.

The ink composition (ink) 111 for writing instruments of this modification is a reversible thermochromic ink containing a reversible thermochromic microcapsule pigment. Therefore, the handwriting formed is thermally discolorable, and may be discolored or discolored by heating or cooling. In addition, it is not limited to this, but also As the ink composition (ink) 111 for a writing instrument, an ink composition other than a thermochromic ink can be used.

微膠囊顏料之平均粒子徑係較佳為0.1μm至5.0μm，更佳為0.1μm至4.0μm，尤佳為0.5μm至3.0μm。藉由將微膠囊顏料之平均粒子徑設為上述數值範圍，可維持高濃度之發色性並使本發明之筆具的書寫感變得更順暢。此外，粒子徑、細微性分佈之測定係可藉由例如庫爾特(Coulter)法(電性檢測帶法)而進行測定。具體而言，利用精密分布測定装置(beckmancoulter公司製，Multisizer4e)來進行測定，根據其數值利用體積基準來算出平均粒子徑(中間值徑)。或者，可利用雷射繞射/散射式粒子徑分佈測定裝置[堀場製作所股份有限公司製；LA-300]來進行測定，並根據利用標準試料校正後之數值，利用體積基準來算出平均粒子徑(中間值徑)。 The average particle diameter of the microcapsule pigment is preferably from 0.1 μm to 5.0 μm, more preferably from 0.1 μm to 4.0 μm, and even more preferably from 0.5 μm to 3.0 μm. By setting the average particle diameter of the microcapsule pigment to the above-mentioned numerical range, it is possible to maintain a high-concentration color development property and make the writing feeling of the writing instrument of the present invention smoother. The particle diameter and the fineness distribution can be measured by, for example, the Coulter method (electrical detection strip method). Specifically, the measurement was performed using a precision distribution measurement device (manufactured by Beckman Coulter, Multisizer 4e), and the average particle diameter (median diameter) was calculated based on the numerical value using a volume basis. Alternatively, a laser diffraction / scattering type particle diameter distribution measuring device [manufactured by Horiba, Ltd .; LA-300] can be used for measurement, and an average particle diameter can be calculated using a volume basis based on a value corrected by a standard sample. (Median diameter).

可逆熱變色性微膠囊顏料之含有量相對於油墨組成物全量較佳為5至40質量%，更佳為10至40質量%，尤佳為15至35質量%。藉由將可逆熱變色性微膠囊顏料之含有量設為上述數值範圍，可維持油墨流出性並提升發色性能。 The content of the reversible thermochromic microcapsule pigment is preferably 5 to 40% by mass, more preferably 10 to 40% by mass, and even more preferably 15 to 35% by mass relative to the total amount of the ink composition. By setting the content of the reversible thermochromic microcapsule pigment to the above-mentioned numerical range, it is possible to maintain ink outflow and improve color development performance.

可逆熱變色性油墨之變色溫度係依據其目的等而適當地設定。例如，在利用因加熱而消色之可逆熱變色性油墨時，因加熱而消色之溫度係較佳為設定成25℃至95℃，更佳為設定成36℃至90℃。更具體而言，可將高溫側變色點[完全消色溫度(t4)〕設定成25℃至95℃，較 佳為設定成36℃至90℃之範圍，且可將低溫側變色點〔完全發色溫度(t1)〕設定成-30℃至+20℃，較佳為設定成-30℃至+10℃之範圍。藉由上述之構成，可在常態(日常之生活溫度域)下有效地保持色彩，且可將筆跡藉由加熱(具體而言係利用後述之摩擦體125等所產生之摩擦熱所致之加熱)而容易地使之消色。 The discoloration temperature of the reversible thermochromic ink is appropriately set depending on the purpose and the like. For example, when using a reversible thermochromic ink which is decolorized by heating, the temperature of decoloring by heating is preferably set to 25 ° C to 95 ° C, and more preferably 36 ° C to 90 ° C. More specifically, the high-temperature-side discoloration point [complete decoloring temperature (t4)] can be set to 25 ° C to 95 ° C, It is preferably set to a range of 36 ° C to 90 ° C, and the low-temperature side discoloration point [complete color development temperature (t1)] can be set to -30 ° C to + 20 ° C, preferably -30 ° C to + 10 ° C Range.

Along with this, in this modification, the tail bolt 125 is also referred to as the friction body 125. The friction body 125 is fixed in such a manner that it cannot rotate relative to the rotating body 106 and cannot move back and forth. The friction body 125 is used to rub, for example, a handwriting generated by the ink composition 111 for a writing instrument having thermal discoloration property, and to cause the handwriting to be discolored (erased) by the frictional heat generated at this time, and the user. The friction body 125 is not limited to this, and the friction body 125 may be a friction body such as a frosted eraser.

In the example shown in the figure, the protruding portion 170c extends linearly along the front-rear direction. Therefore, the extending direction of the guided portion 170b and the extending direction of the protruding portion 170c are parallel to each other. The protrusions 170 are arranged at equal angular intervals in the circumferential direction. In the example shown in FIG. 35, the stopper member 170 has two protruding portions 170c, and each protruding portion 170c is disposed at an angular interval of 180 degrees from each other. The stopper member 170 is not limited to this, and may have one protruding portion 170c or three or more protruding portions 170c.

擋止構件170係具有沿著前後方向貫通本體部170a與被導引部170b之貫通孔170d。貫通孔170d係於本體部170a之後方端面及被導引部170b之前方端面之各者開口。此外，貫通孔170d並非必須之構成要素，擋止構件170亦可不具有貫通孔170d。亦即，擋止構件170亦可構成作為實心之構件。 The stopper member 170 has a through hole 170d penetrating the body portion 170a and the guided portion 170b along the front-rear direction. The through hole 170d is opened at each of the rear end surface of the main body portion 170a and the front end surface of the guided portion 170b. The through hole 170d is not an essential component, and the stopper member 170 may not have the through hole 170d. That is, the stopper member 170 may be configured as a solid member.

如第30圖至第32圖所示，活塞118係具有以可前後移動之方式導引擋止構件170之被導引部170b的導引部118h。導引部118h係於活塞118內朝前後方向延伸，且形成為在活塞118之後方端面開口之孔。在導引部118h之與延伸方向正交之剖面中，導引部118h係具有與擋止構件170之被導引部170b形成互補形狀的輪廓。亦即，在導引部118h之與延伸方向正交之剖面中，導引部 118h係具有大致矩形形狀，特別是具有大致正方形形狀之輪廓。藉此，擋止構件170係以相對於活塞118可前後移動且無法轉動之方式保持。並且，導引部118h之剖面係沿著導引部118h之延伸方向具有固定形狀之輪廓。亦即，導引部118h中之與導引部118h之延伸方向正交之任意二個剖面係具有彼此相同形狀之輪廓。 As shown in FIGS. 30 to 32, the piston 118 has a guide portion 118 h that guides the guided portion 170 b of the stopper member 170 in a forward and backward direction. The guide portion 118h extends in the piston 118 in the front-rear direction and is formed as a hole opened at the rear end surface of the piston 118. In the cross section orthogonal to the extending direction of the guide portion 118h, the guide portion 118h has an outline that forms a complementary shape to the guided portion 170b of the stopper member 170. That is, in a section of the guide portion 118h orthogonal to the extending direction, the guide portion 118h has a generally rectangular shape, especially a contour with a substantially square shape. Thereby, the stopper member 170 is held in such a manner that it can move back and forth with respect to the piston 118 and cannot rotate. The cross-section of the guide portion 118h has a contour having a fixed shape along the extending direction of the guide portion 118h. That is, any two cross-sections of the guide portion 118h that are orthogonal to the extending direction of the guide portion 118h have contours having the same shape as each other.

如第33圖所示，在轉動體106之內周面設置有限制擋止構件170之突出部170c之移動的限制部106h。限制部106h之個數係與擋止構件170之突出部170c的個數相同。亦即，在本變形例中，沿著轉動體106之周方向，二個限制部106h係彼此具有180度之角度間隔而設置。圖示之限制部106h係具有：第1溝部106i；位在第1溝部106i之後方且與第1溝部106i連通之複數個第2溝部106j。第1溝部106i係沿著前後方向而呈直線狀延伸，且沿著轉動體106之周方向具有一定之寬度。第2溝部106j係對應於第一凸輪斜面105e之段部105f及第二凸輪斜面118d之段部118e之個數而設置。亦即，在本變形例中，相對於一個第1溝部106i設置有三個第2溝部106j。各第2溝部106j係沿著前後方向呈直線狀延伸，且沿著轉動體106之周方向排列。各第2溝部106j係在至少前方側(接近第1溝部106i之側)的預定範圍沿著轉動體106之周方向具有一定之寬度。沿著該預定範圍之周方向的第2溝部106j之寬度，係設定為擋止構件170之突出部170c可在該第2溝部106j內順暢地前後移動之程度的大小。另一方 面，從適當地抑制利用摩擦體125來摩擦筆跡時之摩擦體125的轉動之觀點來看，可產生在第2溝部106j與突出部170c之間的周方向之裕度尺寸係以儘可能小者為佳。 As shown in FIG. 33, a restricting portion 106 h that restricts movement of the protruding portion 170 c of the stopper member 170 is provided on the inner peripheral surface of the rotating body 106. The number of the restricting portions 106h is the same as the number of the protruding portions 170c of the stopper member 170. That is, in this modification, the two restricting portions 106 h are provided at an angular interval of 180 degrees from each other along the circumferential direction of the rotating body 106. The restricting portion 106h shown in the figure includes a first groove portion 106i and a plurality of second groove portions 106j located behind the first groove portion 106i and communicating with the first groove portion 106i. The first groove portion 106i extends linearly along the front-rear direction and has a certain width along the circumferential direction of the rotating body 106. The second groove portion 106j is provided corresponding to the number of the segment portion 105f of the first cam inclined surface 105e and the number of the segment portions 118e of the second cam inclined surface 118d. That is, in this modification, three second groove portions 106j are provided for one first groove portion 106i. Each of the second groove portions 106j extends linearly in the front-rear direction and is arranged along the circumferential direction of the rotating body 106. Each of the second groove portions 106j has a predetermined width in a predetermined range at least on the front side (the side close to the first groove portion 106i) along the circumferential direction of the rotating body 106. The width of the second groove portion 106j along the circumferential direction of the predetermined range is set to such an extent that the protruding portion 170c of the stopper member 170 can move back and forth smoothly within the second groove portion 106j. The other side From the viewpoint of properly suppressing the rotation of the friction body 125 when the handwriting is rubbed by the friction body 125, the size of the margin in the circumferential direction between the second groove portion 106j and the protruding portion 170c can be made as small as possible. Those are better.

接著，參照第34圖及第35圖，針對利用本變形例之加壓式筆具201使筆跡消色之方法加以說明。第34圖係顯示為了使筆跡消色而使加壓式筆具201之後端朝向下方之狀態的圖，第35圖係在對應於第34圖之XXXV-XXXV線的剖面中顯示加壓式筆具201之圖。 Next, a method for erasing the handwriting using the pressurized pen tool 201 according to this modification will be described with reference to FIGS. 34 and 35. FIG. 34 is a diagram showing a state in which the rear end of the pressure pen 201 is directed downward in order to decolor the handwriting, and FIG. 35 is a view showing the pressure pen in a section corresponding to the line XXXV-XXXV of FIG. 34 Figure with 201.

如第30圖所示，在使軸筒104之後端朝向上方的狀態下，藉由重力之作用，擋止構件170係位在前方側。此時，擋止構件170之本體部170a的前方端部或被導引部170b之前方端部會抵接於活塞118，被導引部170b之至少前方側的部分係位在活塞118之導引部118h內。並且，擋止構件170之突出部170c係位在轉動體106之限制部106h的第1溝部106i內。因此，突出部170c係可在第1溝部106i之寬度的範圍內沿著周方向移動。亦即，轉動體106係可在第1溝部106i之寬度的範圍內相對於擋止構件170及活塞118轉動。藉此，擋止構件170係在使軸筒104之後端朝向上方之狀態下容許轉動體106之轉動。因此，在使軸筒104之後端朝向上方之狀態下，參照第27A圖至第27C圖，如上所述，藉由使轉動體106轉動而使加壓力調整機構160作動，可調整施加在筆具用油墨組成物(油墨)111之加壓力。 As shown in FIG. 30, in a state where the rear end of the shaft cylinder 104 is directed upward, the stopper member 170 is positioned on the front side by the action of gravity. At this time, the front end portion of the main body portion 170a of the stopper member 170 or the front end portion of the guided portion 170b abuts on the piston 118, and at least the front side portion of the guided portion 170b is positioned on the guide of the piston 118. Lead within 118h. In addition, the protruding portion 170 c of the stopper member 170 is located in the first groove portion 106 i of the restricting portion 106 h of the rotating body 106. Therefore, the protruding portion 170c can move in the circumferential direction within the range of the width of the first groove portion 106i. That is, the rotating body 106 is rotatable with respect to the stopper member 170 and the piston 118 within the range of the width of the first groove portion 106i. Thereby, the stopper member 170 allows the rotation of the rotating body 106 with the rear end of the shaft cylinder 104 facing upward. Therefore, in a state in which the rear end of the shaft cylinder 104 faces upward, referring to FIGS. 27A to 27C, as described above, by rotating the rotating body 106 to actuate the pressure adjustment mechanism 160, it can be adjusted to be applied to the writing instrument. The pressure of the ink composition (ink) 111 was applied.

在利用摩擦體125來摩擦由筆具用油墨組 成物(油墨)111所產生之筆跡而使該筆跡變色(消色)之際，使用者係如第34圖所示，使摩擦體125朝向下方。亦即，使軸筒104之後端朝向下方。藉此，擋止構件170係藉由重力之作用而朝後方移動。此時，擋止構件170之突出部170c係進入轉動體106之限制部106h之複數個第2溝部106j之其中一個(參照第35圖)。具體而言，在對應於對位用標記106f相對於加壓力顯示部102h之指示位置(參照第14圖)之第2溝部106j內，會有突出部170c進入。換言之，在對應於第一凸輪突起106b相對於第一凸輪斜面105e之段部105f1至105f3(參照第28A圖至第28C圖)之嵌合位置的第2溝部106j內，會有突出部170c進入。再者，換言之，在對應於第二凸輪突起106d相對於第二凸輪斜面118d之段部118e1至118e3(參照第28A圖至第28C圖)之嵌合位置的第2溝部106j內，會有突出部170c進入。第2溝部106j之沿著周方向的寬度係比第1溝部106i之沿著周方向的寬度更小，藉此，在使軸筒104之後端朝向下方的狀態下妨礙轉動體106之轉動。因此，在軸筒104之後端朝向下方，且擋止構件170之突出部170c進入至限制部106h之複數個第2溝部106j之其中一個時，藉由使轉動體106轉動所進行之施加在筆具用油墨組成物(油墨)111之加壓力的調整係不可能進行。亦即，此時，在利用摩擦體125來摩擦筆跡之際，轉動體106會與摩擦體125一同轉動，而可防止施加於筆具用油墨組成物(油墨)111之加壓力在使用者不經意的情況下被變更。 The friction body 125 is used to rub the ink set for writing instruments When the handwriting produced by the finished product (ink) 111 changes (decolors) the handwriting, the user causes the friction body 125 to face downward as shown in FIG. 34. That is, the rear end of the shaft cylinder 104 is directed downward. Thereby, the stopper member 170 is moved backward by the action of gravity. At this time, the protruding portion 170c of the stopper member 170 is one of the plurality of second groove portions 106j entering the restricting portion 106h of the rotating body 106 (refer to FIG. 35). Specifically, in the second groove portion 106j corresponding to the indicated position (refer to FIG. 14) of the alignment mark 106f with respect to the pressing force display portion 102h, a protruding portion 170c enters. In other words, in the second groove portion 106j corresponding to the fitting position of the segment portions 105f1 to 105f3 (refer to FIGS. 28A to 28C) of the first cam protrusion 106b with respect to the first cam inclined surface 105e, a protruding portion 170c enters . In other words, in the second groove portion 106j corresponding to the fitting position of the section portions 118e1 to 118e3 (see FIGS. 28A to 28C) of the second cam protrusion 106d with respect to the second cam inclined surface 118d, there is a protrusion. Section 170c enters. The width in the circumferential direction of the second groove portion 106j is smaller than the width in the circumferential direction of the first groove portion 106i, thereby preventing the rotation of the rotating body 106 with the rear end of the shaft cylinder 104 facing downward. Therefore, when the rear end of the shaft cylinder 104 faces downward and the protruding portion 170c of the stopper member 170 enters one of the plurality of second groove portions 106j of the restricting portion 106h, the pen is applied by rotating the rotating body 106. It is impossible to adjust the pressing force of the ink composition (ink) 111. That is, at this time, when the handwriting is rubbed by the friction body 125, the rotating body 106 rotates together with the friction body 125, which can prevent the user from inadvertently applying a pressure applied to the ink composition (ink) 111 of the writing instrument. Was changed.

在本變形例之加壓式筆具201中，筆具用油墨組成物(油墨)111係為熱變色性油墨，且更具備：摩擦體125，係設置在轉動體106之後端，用於摩擦熱變色性油墨之筆跡，可藉由在此時產生之摩擦熱而使該筆跡變色；以及擋止構件170，係在使軸筒104之後端朝向上方之狀態下容許轉動體106之轉動，且在使軸筒104之後端朝向下方之狀態下妨礙轉動體106之轉動。 In the pressurized writing instrument 201 of this modification example, the ink composition (ink) 111 for writing instruments is a thermochromic ink, and further includes a friction body 125 provided at the rear end of the rotating body 106 for friction The handwriting of the thermochromic ink can be discolored by the frictional heat generated at this time; and the stopper member 170 allows the rotation of the rotating body 106 with the rear end of the shaft cylinder 104 facing upward, and When the rear end of the shaft cylinder 104 is directed downward, the rotation of the rotating body 106 is prevented.

依據此種加壓式筆具201，在使軸筒104之後端朝向上方之狀態下，藉由使轉動體106轉動而使加壓力調整機構160作動，可調整施加於筆具用油墨組成物(油墨)111之加壓力。另一方面，在使軸筒104之後端朝向下方並利用摩擦體125使筆跡消色之際，可隨著藉由摩擦體125進行之筆跡的摩擦而妨礙轉動體106之轉動，且可防止施加於筆具用油墨組成物(油墨)111之加壓力不經意地被變更。 According to this pressurized writing instrument 201, with the rear end of the barrel 104 facing upward, the pressure adjusting mechanism 160 is operated by rotating the rotating body 106 to adjust the ink composition applied to the writing instrument ( Ink) 111. On the other hand, when the rear end of the shaft cylinder 104 faces downward and the handwriting is erased by the friction body 125, the rotation of the rotating body 106 can be hindered by the friction of the handwriting by the friction body 125, and the application can be prevented. The pressure applied to the ink composition (ink) 111 for writing instruments is inadvertently changed.
