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 present invention relates to a pressurized writing instrument for applying pressure to an ink composition for writing instruments in an ink container.

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。 In the past, for this kind of pressurized writing instrument, as disclosed in JP2000-335173A, there is a known structure: a pressurizing mechanism is provided at the rear end of the ink containing tube, and the pressing operation of the striking body In conjunction with this, the inside of the ink containing tube is placed in a pressurized state, thereby increasing the amount of ink discharged from the tip of the writing, so as 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 container does not change. Therefore, it may not necessarily be a handwriting width or handwriting that meets the user’s preferences. Concentration situation.

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, as far as the technology to solve this problem is concerned, JPH08-141482A discloses a coating tool that can arbitrarily adjust the pressure applied to the rear end of the correction fluid in 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 coating tool of JPH08-141482A, the structure is as follows: by making the rotating body at the rear end of the barrel rotate stepwise from the starting point of the groove pushing part of the inner end of the barrel to the direction of the end of the pressing, and according to each The height of the pressure part of the section The rear end of the liquid tank is pushed toward the front of the barrel 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 the liquid tank can be pressurized with any strength during use, it is necessary to adjust the pressurizing force by rotating the rotating body every time during use. Sometimes, there is a danger of liquid leakage from the liquid application port in a pressurized state, so it must be stored after rotating the rotating body to its original position, which consumes manpower and 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 type ballpoint pen in which a pressure mechanism is actuated by the pressure of the pen when writing, and the inside of the writing fluid storage tube is placed in a pressurized state.

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 pressure-pressurized ballpoint pen described in JP2011-235612A is designed to make the refill refill of the ball-point pen retreat by the pressure of the pen when writing, so that the pressure mechanism will act to apply pressure to the back end of the ink. Therefore, in order to adjust the pressure applied to the back end of the ink when pressurizing like JPH08-141482A, it is necessary to increase or decrease the retreat of the ballpoint pen refill when the pressure is applied, and accordingly it is difficult to make the ballpoint pen refill. The protruding length of the front end of the pen core from the barrel becomes 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 ball pen varies from person to person, but most of the holding positions are determined based on the position of the pen tip when writing. Therefore, the user must change the position of the grip shaft according to the protruding length of the pen tip, especially when the grip part of the pen is formed by forming unevenness for anti-slip or bending inward or outward in a way that is easy to hold. Changing the holding position will cause a problem that even the holding feeling will change.

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。 The pressure pen set of JP2009-202513A becomes the following Structure: The pressurizing mechanism is equipped with: a cylinder with an air hole communicating with the inside and outside at the rear end; The striker advances forward, so that the rear end of the cylinder is pressed against the bottomed inner wall of the sealing member to close the air hole of the cylinder, and the air in the sealed cylinder is compressed before the cylinder, and the ink container Then pressure is applied to the space at the end.

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, the part formed by compressing the enclosed space must be restored to its original state. Therefore, when the pressurized space is released, if the pressure of the pressurized space reaches close to the atmospheric pressure due to ink consumption, etc., it will become a negative pressure state where the air pressure is lower than the atmospheric pressure, and the ink container may be filled The ink for writing instruments moves toward the rear end side of the ink container, which may cause backflow of the ink. As a countermeasure, the pressurized pen of JP2009-202513A has a structure in which the striking body is pushed backward by the coil spring and the pressurized state of the pressurizing mechanism is released by The elastic thrust of the coil spring releases the sealing of the cylinder block and the sealing member and opens the air hole of the cylinder block. After the cylinder block and the rear end of the ink containing cylinder are set at the same pressure as the atmospheric pressure, the cylinder block will move backwards, thereby releasing When the space is closed, prevent it 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 pressure-pressure-type ballpoint pen system described in JP2011-235612A described above has the following structure: the refill of the ballpoint pen can be moved back by the pressure of the pen during writing, so that the pressure mechanism will actuate the back end of the ink. Pressure is applied, and the writing tip is repeatedly contacted and separated from the paper surface during writing, thereby switching between the pressurized state and the non-pressurized state. therefore, If the refill of the ball pen refills greatly retreat during writing, it will become very difficult to write. Therefore, the retreat of the refill refill of the ball pen during writing must be set to a minimum. Therefore, like the impact-type pressure pen tool like JP2009-202513A, since the impact body cannot be advanced with a long stroke to apply high pressure to the pressure chamber, the pressure is applied by the pressure mechanism. The pressure is also lower than the percussion type. In addition, in the pen pressure type, since the original structure is to reset the pressurized state of the pressurizing chamber every time the tip of the writing is separated from the paper surface, it has the following advantages: it can be compressed by one time Although the pressurized pressure is low, the pressurized state can still be maintained for writing.

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 pressurization state of the pressurization chamber is reset every time you write, and the pressurized pressure with one action will also become lower, it is generated during pressurization reset. The negative pressure state has also become extremely small, but when compared with the percussion type pressure pen tools such as JP2009-202513A, the pressure state is reset very many times during writing, so it is easy to remove the air. From the tip of the writing to the refill refill of the ball pen, there is a risk that the ink will flow backwards and cannot be written.

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, the state in which the ballpoint pen tip 13 belonging to the writing tip of the ballpoint pen refill 8 is protruded and submerged from the front end opening 3a of the front shaft 3 by pushing the rotating body 6 forward (tapping operation) will be described.

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 Figure 1 (in the direction of arrow F in Figure 1), the rotating body 6 will advance relative to the sliding member 5, and the convex portion 6b will abut against the sliding member 5. The rear end, and the sliding member 5 pushed by the rotating body 6 and the washer 15 press-fitted and installed on the sliding member 5, will interact with the rotating body 6 Together, they move forward against the elastic force of the coil spring 16 for knocking. 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 advances, so that the cylindrical body 18 is biased by the coil spring 23 for pressure and advances. In addition, as the cylindrical body 18 advances, the ballpoint pen refill 8 is pushed forward through the elastic member 20 to advance, and the front end of the ballpoint pen tip 13 protrudes from the front end opening 3a of the front shaft 3. At this time, the hooking portion 5a of the sliding member 5 is hooked to the hooked portion 9c at the front end of the jig 9 arranged on the side surface of the rear axle 2, thereby maintaining the front end of the ballpoint pen tip 13 from the front axle 3 (axis Cylinder 4) The state shown in Fig. 6 with the front end opening 3a protruding.

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 clamp 9 (in the direction of arrow G in Fig. 6) is pushed, and the hooking state of the hooking portion 5a of the sliding member 5 hooked to the hooked portion 9c of the clamp 9 is released, By the elastic force of the coil spring 16 for striking, the ball-point pen refill 8, the pressing mechanism 7, the sliding member 22, the sliding member 5, and the rotating bodies and 6 will move 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 the present embodiment, a state in which the pressure is applied to the back end of the ink 11 in the refill 8 of the ball pen through the ink follower 12 using the writing pressure during writing will be described.

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 Figures 6 and 9A, in the state where the front end of the ballpoint pen tip 13 protrudes from the front end opening 3a of the front shaft 3, when the barrel 4 is tilted and held as shown in Figure 7, it complements the ballpoint pen When writing pressure is applied to the front end of the pen core 8 and the ball-point pen refill 8 is retracted in the direction of arrow H in Fig. 7, the sliding member 5 cannot be reared because the hooking portion is locked by the hooked portion 9c of the clamp 9. Retreat, the rotor 6 cannot retreat due to cam fitting with the sliding member 5, and the sliding member 22 cannot retreat due to cam fitting with the rotor 6, so the cylindrical body 18 resists the pressurizing coil spring 23 The elastic force moves back together with the elastic member 20. In addition, when the front end surface 19d of the stopper 19 stopped by the sliding member 22 is in contact with the rear end of the elastic member 20, the air hole 20c is blocked by the front end surface 19d to seal the pressurized space 21. The state of the graph. Furthermore, when the ball-point pen refill 8 retreats and the cylindrical body 18 retreats, the elastic member 20 is elastically deformed, thereby compressing the pressurized space 21 as shown in FIG. 9C, and becomes a pair of penetrating ink followers 12 The ball pen replenishes the state shown in Fig. 8 where pressure is applied to the rear end of the ink 11 in the refill 8. That is, as the ballpoint pen refills the refill 8 and withdraws, the pressure can be applied to the rear end of the ink 11 by the pressure 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 retreat in the direction of arrow H by replenishing the pressure of the refill 8 by a ball pen will stop because the outer section 18c of the cylindrical body 18 abuts against the front end 6g of the rotating body 6. That is, the retreatable length of the ball-point pen refill 8 can be determined according to the size of 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。 In addition, when the writing pressure is released, the cylindrical body 18 and the elastic member 20 move forward (the original position) by the elastic force of the pressurizing coil spring 23 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 is opened to release the sealing of the pressurized space 21 and the inner hole 8a of the rear part of the ballpoint pen refill 8, and becomes the same pressure as the atmospheric pressure. , And return to the state in 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, the operation of adjusting the pressing force applied to the ink 11 by rotating the rotating body 6 relative to the rear axle 2 to actuate the pressing force adjusting mechanism 24 in the striking state of FIG. 6 will be described.

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 (counterclockwise direction) viewed from the rear end side from the state of Fig. 10A to become the state of Fig. 10B, the sliding member 5 is not rotatable relative to the rear axle 2 As shown in Figs. 11A to 11B, the first cam protrusion 6d of the rotating body 6 moves along the first cam slope from the first section 5g1 to the adjacent second section 5g2. At this time, the rotating body 6 moves forward with respect to the sliding member 5 by the amount of L1 (refer to Figure 11A) made by the first cam protrusion 6d moving one step, and at the same time, it is slid backward by the pressurizing coil spring 23 The component also advances by 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。 Furthermore, since the sliding member 22 is locked so as to be unable to rotate relative to the cylindrical body 18, and the cylindrical body 18 is locked to the sliding member 5 so as to be unable to rotate, the sliding member 22 cannot rotate relative to the shaft tube 4 Therefore, as shown in FIGS. 12A to 12B, as the rotor 6 rotates, the second cam protrusion 6f of the rotor 6 moves along the second cam slope 22a of the sliding member 22 from the first section 22b1 to the phase The adjacent second section 22b2. At this time, the sliding member 22 retreats with respect to the rotating body 6 and moves the second cam protrusion 6f by one step by the amount of M1 (refer to FIG. 12A). Therefore, the sliding member 22 is moved forward by the amount of L1 by the first cam mechanism 30 and retreated by the amount of M1 by the second cam mechanism 40. In addition, in this embodiment, since the configuration is L1=M1, only the rotating body 6 advances L1 relative to the shaft cylinder 4, 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 that is urged forward by the pressurizing coil spring 23 does not change, and the atoms of the cylindrical body 18 are fixed to the cylindrical body 18 through the elastic member 20. The relative position of the pen refill 8 relative to the barrel 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 be reduced by the amount of L1 that the rotating body is advancing, so when the pressure is applied, the ballpoint pen refill 8 can be moved back. Length will also reduce the weight of L1. In addition, since the amount of deformation of the elastic member 20 is also reduced when the pen pressure is applied, the pressure applied to the pressurized space 21 is reduced. As a result, by rotating the rotor 6 to the left by a certain amount, it can be applied to the atom The pen replenishes the pressure at the rear end of the ink 11 in the refill 8 to drop.

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。 In addition, from the state of FIG. 10B, the rotating body 6 is further rotated in the left direction (counterclockwise direction) as viewed from the rear end side, and the first cam protrusion 6d is moved along the first cam slope 5f of the sliding member 5, and As shown in Fig. 10C, as shown in Figs. 11B to 11C, by the first cam mechanism 30, the first cam protrusion 6d of the rotating body 6 moves from the second stage 5g2 to the adjacent third The segment 5g3 moves, and as shown in Figures 12B to 12C, the second cam protrusion 6f of the rotating body 6 moves from the second segment 22b2 to the adjacent third segment 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 will not move, and only the rotating body 6 will advance relative to the cylindrical body 18 by the amount of M2 , And the front end 6g of the rotating body 6 abuts against 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 ball-point pen refill 8 cannot be moved back. Even if the pen pressure is applied during writing, the ink 11 will not be pressurized, and it can be used as a non-pressurized pen tool even if it is maintained in this state. In storage, the ballpoint pen refill 8 will not be pressurized. Therefore, by setting it to the state shown in Fig. 10C, the ink 11 can be prevented from flowing out from the tip 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 the present embodiment, the rotating body 6 is rotated in the same manner as during the non-tapping, so that the setting of the pressure applied to the ink 11 can be changed at the time of writing.

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 structure, the pressurized writing instrument 1 of the present embodiment operates the pressurizing pressure adjusting mechanism 24 by rotating the rotating body 6 to adjust the pressurizing force in the ink container 10 according to the user's preference, and Even if the rotor 6 is rotated to change the setting of the pressure applied to the ink 11, the ball-point pen refill 8 will not move back and forth relative to the barrel, so the front end of the ball-point pen refill 8 is from the front end of the front shaft 3. The protruding length of the opening 3a does not change, and the writing instrument can be used without changing the position when holding it.

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 writing instrument 1 of this embodiment is equipped with: a barrel 4, which can house a refill refill 8 filled with the ink composition (ink) 11 for writing instruments; The pen core 8 retreats to apply pressure to the ink composition (ink) 11 for writing instruments; and the pressure adjusting mechanism 24 adjusts 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 pen tool 1, the ink composition (ink) 11 for the pen tool in the refill refill 8 can be applied with the retreat of the refill refill 8 by the pen pressure during writing In the pressure-pressurized writing instrument 1, the pressure adjustment mechanism 24 can be used to adjust the ink composition (oil The pressure exerted by the ink 11 changes the outflow of the ink composition (ink) 11 for writing instruments that flows out from the refill refill 8 during writing. In this way, the thickness and/or density of the handwriting can be adjusted according to the user's preference.

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 pressure-type writing instrument 1 of the present embodiment further includes a rotating body 6 protruding 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 pressure applied to the ink composition (ink) 11 for writing instrument by rotating the rotating body 6 by the user.

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 of this embodiment is constructed by accommodating a ball-point pen refill 8 in a barrel 4, and the ball-point pen refill 8 is provided with: a pen-tool ink composition (ink) 11 The ink container 10; and the ballpoint pen tip 13 at the front of the ink container 10; and the pressure mechanism 7 is arranged behind the ballpoint pen refill 8 to make the ballpoint pen refill by applying pen pressure 8 When retreating, the pressing mechanism 7 applies pressure to the rear end of the ink composition (ink) 11 for writing instruments; wherein, behind the pressing mechanism 7 is provided: a rotating body 6 protruding from the rear end of the barrel 4; And by rotating the rotating body 6 to actuate the pressure adjustment mechanism 24 to adjust the amount of retraction of the refill 8 of the ballpoint pen; The rotating body 6 is locked in a freely rotatable manner relative to the shaft barrel 4; and the pressurized writing instrument 1 is configured as: by rotating the rotating body 6 to actuate the pressurizing adjustment mechanism 24 to adjust The pressure is applied to the back end of the ink composition (ink) 11 for writing instruments in the ink containing cylinder 10, and before and after the rotating body 6 is rotated, the The relative position of the ball-point pen refill 8 with respect to the barrel 4 in the axial direction will 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 adjusting mechanism 24 that changes the retraction amount of the ballpoint pen refill 8 is activated by rotating the rotating body 6, so as to adjust the ink applied to the writing instrument during writing. The pressure at the rear end of the composition (ink) 11 changes the amount of ink composition (ink) 11 for writing instruments that flows out from the front end of the ball pen tip 13 of the ballpoint pen refill 8 to suit the user’s preferences. Adjust the thickness or density 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, the pressure-type writing instrument 1 of the present embodiment is a so-called pressure-pressure type, and therefore pressure is applied to the rear end of the ink composition (ink) 11 for writing instruments only when the writing pressure is applied. Therefore, pressure is not applied to the back end of the ink composition (ink) 11 for writing instruments during non-writing or storage, and ink leakage from the front end of the ballpoint pen tip 13 can be prevented.

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。 Furthermore, when the rotating body 6 is rotated, since the relative position of the ball-point pen refill 8 and the barrel 4 in the axial direction does not change, the front end of the ball-point pen refill 8 is from the barrel 4 4 The protruding length of the front end opening 3a does not change. Therefore, even if the pressure is adjusted, there is no need to change the position of the holding shaft cylinder 4, and writing can be continued while keeping the sense of distance to the paper surface or the holding position 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 pressure-type writing instrument 1 of this embodiment, the shaft barrel 4 is provided with a sliding member 5 that is locked in such a way that it cannot rotate with respect to the shaft barrel 4 but can move forward and backward; a sliding member The 5 series is equipped with: a pressurizing mechanism 7 arranged on the inner side of the sliding member 5; The rotating body 6 is arranged such that the opening at the rear end of the sliding member 5 protrudes rearward; the pressure-type writing instrument 1 is configured to push the rotating body 6 forward so that the ballpoint pen replenishes the refill 8 The front end portion protrudes from the front end opening portion 3a of the shaft cylinder 4.

此外，係構成為：缸體117相對於氣密閥119之前後移動係因外側突起119d之前端與側孔117c之前端相抵接、或凸緣部119g之後端與缸體117之前端相抵接而受到限制。 In addition, the configuration is such that the front and rear movement of the cylinder 117 relative to the airtight valve 119 is caused by the front end of the outer protrusion 119d abutting the front end of the side hole 117c, or the rear end of the flange 119g abutting the front end of the cylinder 117 restricted.

並且，在氣密閥119之後部外周面形成有朝軸周方向延伸之溝部119e，在溝部119e中，裝設有由利用JIS-K6235所測定之硬度計A硬度50的聚矽氧橡膠所形成的第二O環123作為氣密用變形部。 In addition, a groove 119e extending in the axial circumferential direction is formed on the outer peripheral surface of the rear portion of the airtight valve 119, and the groove 119e is formed of silicone rubber having a hardness of 50 with a durometer A as measured by JIS-K6235. The second O-ring 123 serves as a deformed portion for airtightness.

此外，第二O環123(氣密用變形部)係以可與缸體117之抵接部117g(側孔117c之後端)抵接之方式構成，且構成為：當第二O環123(氣密用變形部)與缸體117之抵接部117g(側孔117c之後端)處於抵接狀態時，加壓空間121會被密閉而成為氣密狀態，並且當第二環123(氣密用變形部)與缸體117之抵接部117g(側孔117c之後端)成為非抵接狀 態時，係構成為：利用第二O環123(氣密用變形部)與缸體117之側孔117c之後端部之間的間隙、與側孔117c而形成加壓空間121與加壓式筆具101之外部相連通的空氣通路124，加壓空間121會成為與外氣同壓之狀態。 In addition, the second O-ring 123 (the deformed portion for airtightness) is configured to be able to abut against the abutting portion 117g (rear end of the side hole 117c) of the cylinder 117, and is configured such that when the second O-ring 123 ( When the airtight deformation portion) is in contact with the abutting portion 117g (rear end of the side hole 117c) of the cylinder 117, the pressurized space 121 is sealed to become an airtight state, and when the second ring 123 (airtight Deformation part) and the contact part 117g of the cylinder 117 (the rear end of the side hole 117c) becomes a non-contact shape In this state, the system is configured to use the gap between the second O-ring 123 (the deformed portion for airtightness) and the rear end of the side hole 117c of the cylinder 117 and the side hole 117c to form a pressurized space 121 and a pressurized type With the air passage 124 communicating with the outside of the writing instrument 101, the pressurized space 121 will be at the same pressure as the outside air.

並且，在氣密閥119之內孔119a形成有後方內段部119f，且在後方內段部119f與活塞118之前端凹部118a之間架設加壓用線圈彈簧120，藉此將氣密閥119相對於活塞118朝前方彈壓。 In addition, a rear inner section 119f is formed in the inner hole 119a of the airtight valve 119, and a pressurizing coil spring 120 is bridged between the rear inner section 119f and the front end recess 118a of the piston 118, thereby closing the airtight valve 119 The piston 118 is urged forward.

再者，氣密閥119之凸緣部119g係構成為與墊圈114之後端抵接，因此活塞118亦成為透過氣密閥119由加壓用線圈彈簧120朝後方彈壓之狀態。 Furthermore, the flange portion 119g of the airtight valve 119 is configured to abut against the rear end of the washer 114, and therefore the piston 118 is also in a state of being urged backward by the pressurizing coil spring 120 through the airtight valve 119.

接著，針對轉動體106詳細地說明，如第15圖至第16圖所示，轉動體106係裝設成：從該滑移構件105之前端開口部***至滑移構件105之內部，且一部分從滑移構件105之後方開口部朝後方突出。 Next, the rotating body 106 will be described in detail. As shown in FIGS. 15 to 16, the rotating body 106 is installed so that it is inserted into the inside of the sliding member 105 from the opening of the front end of the sliding member 105, and partly The opening from the rear of the sliding member 105 protrudes rearward.

再者，如第17圖所示，在轉動體106形成有：以從前部外周面106a朝向後方延伸之方式形成之第一凸輪突起106b；及以從後部內周面106c朝前方延伸之方式形成之第二凸輪突起106d。 Furthermore, as shown in FIG. 17, the rotor 106 is formed with a first cam protrusion 106b formed to extend from the front outer peripheral surface 106a toward the rear; and a first cam protrusion 106b formed to extend from the rear inner peripheral surface 106c toward the front The second cam protrusion 106d.

此外，藉由使轉動體106之第一凸輪突起106b與滑移構件105之第一凸輪斜面105e進行凸輪嵌合，而構成第一凸輪機構140，藉由使轉動體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，而構成第二凸輪機構150。 In addition, by cam-fitting the first cam protrusion 106b of the rotating body 106 with the first cam slope 105e of the sliding member 105, the first cam mechanism 140 is formed, and the second cam protrusion 106d of the rotating body 106 The second cam slant surface 118d of the piston 118 is cam-fitted to form a second cam mechanism 150.

再者，如第14圖所示，在轉動體106之後部外周面形成有呈凹狀且從側面觀看形成為三角形狀的對位用標記106f。 Furthermore, as shown in FIG. 14, on the outer peripheral surface of the rear part of the rotating body 106, there is formed an alignment mark 106f that has a concave shape and is formed in a triangular shape when viewed from the side.

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 rotor 106 is rotated while the rotor 106 is knocked forward, the front end top 106g of the alignment mark 106f is aligned with the pressure display portion 102h of the rear axle 102 And read the number at the front of the linear part to identify the pressure applied to the back 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 portion 102h, the pressure in the pressure space (pressurization chamber) 121 is adjusted to the maximum state ( Figure 27A), when aligned to "2", it is adjusted to a state where low pressure is applied (Figure 27B), when aligned 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。 Furthermore, a tail bolt 125 formed of a thermoplastic elastomer is press-fitted in the opening at the rear end of the rotor 106, and a plurality of protrusions extending in the axial direction are equally arranged on the side of the tail bolt 125 in the axial circumferential direction. The shaped portion makes it difficult to slide when rotating 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 constituted: the pressure adjusting mechanism 160 can change the pressure of the pressurizing space 121 by rotating the rotating body 106.

接著，說明藉由將轉動體106朝前方推壓(敲擊操作)而使屬於原子筆補充筆芯108之書寫前端的原子筆尖113從前軸103之前端開口部103a突出沒入的狀態。 Next, the state in which the ballpoint pen tip 113 belonging to the writing tip of the ballpoint pen refill 108 is protruded and submerged from the front end opening 103a of the front shaft 103 by pushing the rotor 106 forward (tapping operation) will be described.

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 rotor 106 resist knocking from the state shown in Figure 15 When the elastic force of the hitting coil spring 115 pushes forward (in the direction of arrow F in Fig. 15), the second cam protrusion 106d of the rotor 106 is cam-fitted with the second cam slope 118d of the piston 118, so the piston 118 It is pushed by the rotating body 106 and moves forward together with the rotating body 106. However, when the front end 106e of the rotor 106 abuts against the rear end 117f of the cylinder 117, the cylinder 117 will move forward. When the front end of the cylinder 117 abuts the flange portion 119g of the airtight valve 119, the airtight valve 119 The ball-point pen refill 108 installed on the installation portion 119c of the airtight valve 119 advances together with the cylinder 117, and the tip of the ball-point pen tip 113 of the ball-point pen refill 108 opens from the front end of the front shaft 103 103a is prominent.

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 with the slit locking portion 105d of the sliding member 105 in a manner that moves freely back and forth, so that the locking protrusion 117b of the cylinder 117 that moves forward will abut against The front end of the locking portion 105d is slit so that the sliding member 105 starts to advance, and the hooking portion 105a of the sliding member 105 is hooked to the hooked portion 109c of the front end of the clamp 109 arranged on the side of the rear axle 102 As a result, the tip of the ballpoint pen tip 113 of the ballpoint pen refill 108 maintains the state of protruding from the front end opening 103a of the front shaft 103 (the barrel 104) as shown in Fig. 20.

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 of the clamp 109 is pushed (in the direction of arrow G in Fig. 20), and the hooking state of the hooking portion 105a of the sliding member 105 hooked to the hooked portion 109c of the clamp 109 is released, By the elastic force of the coil spring 115 for striking, the ballpoint pen refill 108, the pressing 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, a state in which the pressure is applied through the ink follower 112 to the rear end of the ink 111 in the refill 108 of the ball pen will be described using the writing pressure during 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 the state where the tip of the ballpoint pen tip 113 in Figures 20 and 23 protrudes from the front end opening 103a of the front shaft 103, when the barrel 104 is tilted and held as shown in Figure 21, the tip of the ballpoint pen tip 113 is applied When the ball-point pen refill 108 is retracted in the direction of arrow H in Figure 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 is opposed to The sliding member 105 is cam-fitted and cannot be retreated, and the piston 118 is cam-fitted with the rotating body 106 and cannot be retreated. Therefore, the airtight valve 119 resists the elastic force of the pressurizing coil spring 120 and engages the ballpoint pen. The refill 108 retreats together. Furthermore, when the second O-ring 123 fixed to the airtight valve 119 abuts against the abutment portion 117g (rear end of the side hole 117c) of the cylinder 117, it becomes the pressurized space (pressurization chamber) 121 and the outside The communicating air passage 124 is closed and the pressurized space 121 is airtight as shown in Fig. 24. Furthermore, when the ball-point pen refill 108 retreats, the cylinder 117 and the airtight valve 119 retreat relative to the piston 118, and the volume of the pressurized space 121 is reduced, thereby becoming compressed in the pressurized space 121 , Through the ink follower 112 and through the inner hole 119a of the air-tight valve 119, pressure is applied to the rear end of the ink 111 in the refill 108 of the ballpoint pen as shown in Figures 22 and 25.

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 writing 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 elastic force of the pressure coil spring 120. At this point, use the pen pressure to move the first The second O-ring 123 is pressed to the abutting portion 117g (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 in a lightly fitted state. Therefore, the cylinder 117 will be pulled forward in cooperation with the airtight valve 119, and the cylinder 117 will also move forward at the same time. However, since the fitting force acting between the piston 118 and the cylinder 117 by the first O-ring 122 is set to be greater than the fitting force acting between the airtight valve 119 and the cylinder 117 by the second O-ring 123 The resultant force is greater, so the cylinder 117 does not move relative to the piston 118, and only the airtight valve 119 enters the state shown in FIG. 26. Thereby, when the second O-ring 123 is separated from the abutting portion 117g (rear end of the side hole 117c) of the cylinder 117, an air passage 124 is formed to connect the pressurized 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 airtight valve 119 after advancing abuts against the front end of the side hole 117c of the cylinder 117, the cylinder 117 also starts to advance with a delay, and returns to Figs. 20 and 23 The state. As a result, by writing with the pressurized writing instrument 101 in the state where the pen pressure has been applied, the ink 111 in the ink container 110 will be consumed. Even if the pressurized space 121 is reduced accordingly, the pen pressure will still be released. When the air-tight valve 119 advances before the cylinder 117 advances, the air passage 124 is formed, so that the pressurized space 121 becomes the same pressure as the atmosphere, so the pressurized space 121 will not be compressed by the pen pressure. The same forced decompression can prevent it from becoming a negative pressure 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, for one example, the configuration is such that in the state of Fig. 22 and Fig. 25 where pen pressure is applied to the tip of the ballpoint pen tip 113 of the present embodiment, the airtight valve 119 and the cylinder are connected by the second O ring 123. Body 117 The fitting force (the pushing force required to move the cylinder 117 relative to the airtight valve 119) is 0.1N, and the fitting force between the piston 118 and the cylinder 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 writing pressure is released, the cylinder 117 will not move relative to the piston 118, and only the airtight valve 119 is moved forward.

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, the operation of adjusting the pressing force applied to the ink 111 by rotating the rotating body 106 relative to the rear axle 102 to actuate the pressing force adjusting mechanism 160 in the striking state of FIG. 20 will be described.

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 rotor 106 is rotated in the left direction (counterclockwise) as viewed from the rear end from the state of Figure 20 and Figure 27A, the top 106g of the front end of the alignment mark 106f of the rotor 106 (refer to Figure 14 ) When the "3" of the pressure display part 102h of the rear axle 102 is aligned to the position of "2", and the state of Fig. 27B is reached, the sliding member 105 is locked in such a way 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 is along the first cam slope 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 moves forward relative to the sliding member 105 by the amount of L1 that the first cam protrusion 106b moves one step (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。 Furthermore, the piston 118 is locked by the cylinder 117 and the sliding member 105 so as to be unable to rotate with respect to the rear axle 102 (the barrel 104). Therefore, as shown in FIGS. 29A to 29B, the accompanying rotating body With the rotation of 106, the second cam protrusion 106d of the rotating body 106 moves along the second cam slope 118d of the piston 118 from the first section 118e1 to the adjacent second section 118e2. At this time, the piston 118 is retracted relative to the rotor 106 by the second cam protrusion 106d moves the amount of M1 made by one segment (refer to Figure 29A). Therefore, the piston 118 advances by the amount of L1 by the first cam mechanism 140 and retreats by the amount of M1 by the second cam mechanism 150. In addition, in the present embodiment, since the configuration is L1=M1, only the rotor 106 advances with respect to the barrel 104 by the amount of L1, and the relative position of the piston 118 does not change with respect to the barrel 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 pressurizing coil spring 120 does not change. The relative position of the ball-point pen refill 108 with respect to the barrel 104 will not change. Therefore, the gap between the rear end 117f of the cylinder 117 and the front end 106e of the rotor 106 will be reduced by the amount of L1 that the rotor 106 advances. Therefore, when the pen pressure is applied, the refilling length of the ballpoint pen refill 108 can also be retreated. The weight of L1 will be reduced, and the compression amount of the pressurized space (pressurization chamber) 121 will be reduced, so the pressure applied in the pressurized space 121 will drop. 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。 And, from the state of Figure 27B, rotate the rotor 106 to the left (counterclockwise) until the top 106g (refer to Figure 14) of the front end of the alignment mark 106f of the rotor 106 is displayed from the pressure on the rear axle 102 The "2" of the portion 102h is aligned to the position of "1", so that the first cam protrusion 106b moves along the first cam slope 105e of the sliding member 105 and becomes the state of FIG. 27C, as shown in FIGS. 28B to As shown in Figure 28C, by the first cam mechanism 140, the first cam protrusion 106b of the rotating body 106 It moves from the second section 105f2 to the adjacent third section 105f3, and as shown in Figs. 29B to 29C, by the second cam mechanism 150, the second cam protrusion 106d of the rotating body 106 is moved from the first The two-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 is the same as the movement amount M2 of the second cam protrusion 106d, the piston 118 will not move, and only the rotating body 106 will move forward by M2 relative to the cylinder 117. In addition, the front end 106e of the rotating body 106 abuts against 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 117 abuts the front end 106e of the rotating body 106 and cannot retreat, the retreat length of the ballpoint pen refill 108 is also reduced, and the pressurized space 121 cannot be sealed. Therefore, even if the pen pressure is applied during writing, the ink 111 will not be pressurized by the pressurizing mechanism 130, and can be used as a non-pressurized writing instrument, even if it is stored in a tapped state. The ballpoint 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 ballpoint 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 rotating body 106 is rotated in the same manner as during the non-tapping, so that the setting of the pressure applied to the ink 111 can be changed at the time of writing.

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 the present embodiment, as an example, the position of "3" of the pressing force display portion 102h of the rear axle 102 is applied while the alignment mark 106f of the rotating body 106 is aligned with the position of "3". The pressurized state in the pressurized space 121 when the pressurizing mechanism 130 is activated is 1040hpa when the atmospheric pressure is set to 1000hpa. When the alignment mark 106f is aligned In the state of "2" of the pressure display unit 102h, it is 1020 hpa. When the alignment mark 106f is aligned with the position of "1", since there is no pressure, 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 structure, the pressurized writing instrument 101 of the present embodiment rotates the rotating body 106 and activates the pressurizing force adjusting mechanism 160 to adjust the pressurizing force in the ink container 110 according to the user's preference. The amount of ink sent from the front end of the ballpoint pen tip 113 can increase the thickness or density of the handwriting, and even if the rotor 106 is rotated to change the setting of the pressure applied to the ink 111, the ballpoint pen refill 108 will not be refilled. It moves back and forth relative to the barrel, so 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 tool can be used without changing the holding position. In addition, it is possible to provide a pressurized writing instrument that makes the pressurized space 121 (pressurization chamber) a negative pressure when the pen pressure is released, and can prevent the backflow of the ink 111 in the ink container 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 pressure-type writing instrument 101 of this embodiment is constructed by accommodating a ball-point pen refill 108 in a barrel 104, and the ball-point pen refill 108 is provided with: the ink composition (ink) 111 for writing instruments is filled with The ink container 110; and the ballpoint pen tip 113 at the front of the ink container 110; and the pressure mechanism 130 is arranged behind the ballpoint pen refill 108, so that the ballpoint pen refills the refill by applying pen pressure When 108 retreats, the pressurizing mechanism 130 applies pressure to the rear end of the ink composition 111 for writing instruments; wherein, the pressurizing mechanism 130 includes: a cylinder 117 formed in a cylindrical shape; and an airtight valve 119 It has an airtight deformation portion (second O-ring) 123 on the outer peripheral surface, and is formed so as to move forward and backward relative to the cylinder 117; the piston 118, It is installed in the inner hole 117d at the rear of the cylinder 11 in a way that moves freely from front to back; the airtight member (first O-ring) 122 is arranged between the piston 118 and the cylinder 117; the pressurizing chamber (pressurizing space) 121, is surrounded by the cylinder 117, the airtight valve 119, the piston 118, and the airtight member (first O-ring) 122, and is connected to the back of the ballpoint pen refill 108; the elastic member (coil spring for pressure) ) 120, which is arranged between the airtight valve 119 and the piston 118, and makes the airtight valve 119 spring forward; when pressure is applied to the front end of the ballpoint pen tip 113, the ballpoint pen refill 108 will move back, and The ballpoint pen refills the refill 108 and then moves back and forth. The cylinder 117 and the airtight valve 119 will resist the elastic force of the elastic member (coil spring for pressure) 120 and move backward with respect to the piston 118. The pressure space) 121 is sealed and compressed and pressurized. When the pressure applied to the ballpoint pen refill 108 is released, the air-tight valve 119 will advance relative to the piston 118 before the cylinder 117, thereby forming a The pressurized chamber (pressurized space) 121 communicates with the air passage 124 to the outside, and the airtight state of the pressurized chamber (pressurized space) 121 is released to become the same pressure as the atmospheric pressure, and then the cylinder 117 advances with a 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 writing instrument 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 elastic pressure of the elastic member (coil spring for pressure) 120 The piston 118 is moved backward, and the pressurization chamber (pressurization space) 121 is sealed, compressed and pressurized. When the pressure applied to the ballpoint pen refill 108 is released, the airtight valve 119 will be higher than the cylinder 117. First, it advances relative to the piston 118, thereby forming an air passage 124 that communicates the pressurizing chamber (pressurizing space) 121 with the outside. Therefore, even if the ink for writing instruments in the ink container 110 is consumed due to writing, Decrease the pressure in the pressurized chamber (pressurized space) 121, and the relative position of the airtight valve 119, the cylinder 117 and the piston 118 will return after the airtight state of the pressurized chamber (pressurized space) 121 is released. The state before pen pressure is applied can prevent the pressure in the pressurized chamber (pressurized space) 121 from becoming a negative pressure state lower than the atmospheric pressure, and can prevent backflow of ink caused by air entrained 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 pressure-type writing instrument 101 of the present embodiment is configured to make the airtight deforming part (second O ring) of the airtight valve 119 when writing pressure is applied to the tip end of the refill 108 of the ballpoint pen. 123 abuts against the abutting portion of the cylinder 117, thereby making the pressurization chamber (pressurization space) 121 airtight; and is configured to release the pressure applied to the refill 108 of the ball pen, The fitting force between the piston 118 and the cylinder 117 generated by the airtight member (first O-ring) 122 is greater than that generated by the airtight deforming portion (second O-ring) 123 of the airtight valve 119 The fitting force between the airtight valve 119 and the abutting portion of the cylinder 117 is greater, so that the airtight valve 119 advances with respect 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 pressurized writing instrument 101, the cylinder 117, which is pushed back by the airtight valve 119 when the writing pressure is applied, is pushed back by the airtight member (the first O ring) 122 is generated in the fitting force between the piston 118 and cannot keep up with the airtight valve 119, so that the airtight deformation portion (second O ring) 123 of the airtight valve 119 and the front part of the cylinder 117 The abutment 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 the Release before cylinder 117 moves forward The airtight state in the pressurized chamber (pressurized 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 this embodiment, when the writing pressure is released, the fitting force between the airtight valve 119 and the inner end of the front part of the cylinder 117 is generated by the airtight deforming part (second O-ring) 123, and The fitting force generated between the piston 118 and the cylinder 117 by the airtight member (first O-ring) 122 refers to the pressing force required to slide the cylinder 117 relative to the airtight member (first O-ring) 122 , And the pushing force required to make the cylinder 117 slide with respect to the piston 118, each fitting force can be measured by using a push-pull gauge.

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。 Furthermore, the airtight deforming portion (second O-ring) 123 of the airtight valve 119 of this embodiment may be integrally formed on the side surface of the airtight valve 119 by two-color molding or the like, or it may have It is formed by rubber elastic O-ring and other parts. In addition, as for the material constituting the deformable portion (second O ring) 123 for airtightness, it is possible to use rubber with silicone rubber, nitrile rubber, ethylene-propylene-diene rubber, fluororesin, thermoplastic elastomer, etc. The elastic synthetic resin, in terms of the hardness of durometer A as measured by JIS-K6235, the hardness is preferably 20 or more and 90 or less, so that it is easy to contact the O-ring and the inner end of the front part of the cylinder 117 The inside of the pressurized chamber (pressurized space) 121 is 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。 Furthermore, the airtight member (first O-ring) 122 arranged between the cylinder 117 and the piston 118 preferably seals the cylinder 117 and the piston 118 to form an airtight state, and in order to The body 117 and the piston 118 generate moderate friction and are fixed to either the cylinder 117 or the piston 118. When the ease of assembly is considered, it is preferable to be locked on the outer periphery of the piston 118. In addition, the deformed portion (second O-ring) 123 for airtightness with the airtight valve 119 Similarly, the airtight member (first O-ring) 122 may also 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 (first O ring) 122, a rubber elastic compound such as silicone rubber, nitrile rubber, ethylene-propylene-diene rubber, fluororesin, and thermoplastic elastomer can be used. For the resin, the hardness of the resin is preferably 20 or more and 70 or less in terms of the hardness of the durometer A as 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 compared with the air in a sealed pressurized chamber (pressurization space) 121 which is connected to the back end of the ink for writing instrument contained in the ink container 110. The atmospheric pressure is higher and the ink for writing instruments can be easily discharged. The degree of pressure can be appropriately set according to the viscosity of the ink for writing instruments or the structure of the ballpoint pen 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, ink for writing instruments with low viscosity (for example, ink for writing instruments with a viscosity of 1 mPa·s to 2000 mPa·s in an environment of 20°C) can be used by The air pressure of the sealed air in the pressurization chamber (pressurization space) 121 is set to a pressurized state exceeding 1005 hPa and becomes a range of 1500 hPa, so that the ink for writing instruments can be 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 water-based inks with reduced shear rate and viscosity, the increase or decrease in the ink discharge volume caused by pressure will increase, and the thickness, width, or density of the handwriting will be affected by the pressure. The difference caused by the change is also large, so it can be used appropriately. Furthermore, in the use of thermochromic inks using microcapsule pigments As the ink, since the handwriting tends to become thinner in general, it is desirable to increase the ink ejection volume. However, when the ink ejection volume becomes higher, the writing distance is also affected greatly, so it can be used appropriately and can be used to match the application to increase the pressure. The invention.

In the following description and the drawings used in the following description, for parts that can be configured similarly to the second embodiment, the same symbols as those used for the corresponding parts of the second embodiment are used, and repeated descriptions are omitted. . Furthermore, when the effects obtained in the second embodiment can of course also be obtained in the modified example, the description thereof may be omitted.

FIG. 33 is a longitudinal sectional view showing an enlarged display of the rotating body 106 of the pressure pen 201.

在本變形例之加壓式筆具201中，係針對使用熱變色性油墨作為填充於原子筆補充筆芯108之筆具用油墨組成物111之例加以說明。本變形例之筆具用油墨組成物(油墨)111係包含可逆熱變色性微膠囊顏料之可逆熱變色性油墨。因此，所形成之筆跡係具有熱變色性，且會因加熱或冷卻而變色或消色。此外，並不限定於此，亦 可利用熱變色性油墨以外之其他油墨組成物來作為筆具用油墨組成物(油墨)111。 In the pressure-type writing instrument 201 of this modification, an example of using thermochromic ink as the writing instrument ink composition 111 filled in the ballpoint pen refill 108 will be described. The ink composition (ink) 111 for writing instruments of this modification is a reversible thermochromic ink containing a reversible thermochromic microcapsule pigment. Therefore, the formed handwriting has thermal discoloration, and will change color or disappear due to heating or cooling. In addition, it is not limited to this, but also An ink composition other than the thermochromic ink can be used as the ink composition (ink) 111 for writing instruments.

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 0.1 μm to 5.0 μm, more preferably 0.1 μm to 4.0 μm, and particularly preferably 0.5 μm to 3.0 μm. By setting the average particle diameter of the microcapsule pigment within the above-mentioned numerical range, high-concentration color development can be maintained and the writing feeling of the writing instrument of the present invention becomes smoother. In addition, the particle diameter and fineness distribution can be measured by, for example, the Coulter method (electrical detection band method). Specifically, the measurement was performed with a precision distribution measuring device (manufactured by Beckman Coulter, Multisizer 4e), and the average particle diameter (median diameter) was calculated based on the value using a volume basis. Alternatively, a laser diffraction/scattering particle diameter distribution measuring device [manufactured by Horiba Manufacturing Co., Ltd.; LA-300] can be used for measurement, and the average particle diameter can be calculated using the volume standard based on the value after calibration with 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 relative to the total amount of the ink composition is preferably 5 to 40% by mass, more preferably 10 to 40% by mass, and particularly preferably 15 to 35% by mass. By setting the content of the reversible thermochromic microcapsule pigment within the above numerical range, the ink flowability can be maintained and the color development performance can be improved.

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 color change temperature of the reversible thermochromic ink is appropriately set according to its purpose and the like. For example, when using a reversible thermochromic ink that is decolorized by heating, the temperature for decolorization by heating is preferably set to 25°C to 95°C, more preferably 36°C to 90°C. More specifically, the high-temperature side discoloration point [complete decolorization temperature (t4)] can be set to 25°C to 95°C. It is better to set the temperature in the range of 36°C to 90°C, and the low-temperature side color change point [full color temperature (t1)] can be set to -30°C to +20°C, preferably -30°C to +10°C The scope. With the above structure, the color can be effectively maintained under normal conditions (daily life temperature range), and the handwriting can be heated by heating (specifically, the heating caused by the friction heat generated by the friction body 125 described later) ) And easily decolorize it.

In particular, in the example shown in FIG. 30, the tail bolt 125 is configured as a friction body. In connection with this, in this modification, the tail bolt 125 is also referred to as a friction body 125. The friction body 125 is fixed in such a way that it cannot rotate relative to the rotating body 106 and cannot move back and forth. The friction body 125 is used for rubbing the handwriting generated by the ink composition 111 for writing instruments with thermochromic property, for example, and the handwriting is discolored (discolored) by the frictional heat generated at the time, and the user is rendered. In addition, it is not limited to this, and the friction body 125 may be a friction body such as a frosted eraser. The friction body 125 is made of, for example, an elastic material, and can be fixed to the rear end of the rotating body 106 by pressing, engaging, screwing, fitting, bonding, and two-color molding.

The stop member 170 allows the rotation of the rotating body 106 in the state where the rear end of the shaft cylinder 104 faces upward (Figure 30), and prevents the rotation when the rear end of the shaft cylinder 104 faces downward (Figure 34). The body 106 is a functional component of rotation. Here, “bottom” refers to the direction in which gravity acts, and “up” refers to the direction opposite to the bottom, that is, the direction opposite to the direction in which gravity acts. And make the axis The state where the rear end of the barrel 104 faces upward refers to the state where the rear end of the shaft barrel 104 is located above the front end of the shaft barrel 104, and the state where the rear end of the shaft barrel 104 faces downward means that the rear end of the shaft barrel 104 is located more than the shaft.

Furthermore, allowing the rotation of the rotor 106 in the state where the rear end of the shaft cylinder 104 is upward is not only in all states where the rear end of the shaft cylinder 104 is at a position higher than the front end of the shaft cylinder 104 Allowing the rotation of the rotating body 106 also includes allowing the rotation of the rotating body 106 in a partial state of the posture in which the rear end of the shaft tube 104 is located on the upper side of the front end of the shaft tube 104. Similarly, hindering the rotation of the rotating body 106 with the rear end of the shaft tube 104 facing downward means not only in all the states in which the rear end of the shaft tube 104 is at a position lower than the front end of the shaft tube 104 In addition to obstructing the rotation of the rotating body 106, it also includes obstructing the rotation of the rotating body 106 in a part of the state in which the rear end of the shaft tube 104 is located at a position lower than the front end of the shaft tube 104.

在第30圖及第32圖所示之例中，擋止構件170係具備：本體部170a；相對於本體部170a位於前方之被導引部170b；及設置在本體部170a之外周面的突出部170c。本體部170a係具有大致圓筒狀之形狀。被導引部170b係從本體部170a之前側部分朝前方呈直線狀延伸而出。如第31圖所示，在與被導引部170b之延伸方向正交之剖面上，被導引部170b係具有大致矩形形狀、特別是大致正方形形狀之輪廓。並且，被導引部170b之剖面係沿著被導引部170b之延伸方向具有固定形狀之輪廓。亦即， 被導引部170b中之與被導引部170b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。 In the example shown in FIGS. 30 and 32, the stopper member 170 is provided with: a main body 170a; a guided portion 170b positioned forward with respect to the main body 170a; and a protrusion provided on the outer peripheral surface of the main body 170a部170c. The main body 170a has a substantially cylindrical shape. The guided portion 170b linearly extends from the front side portion of the main body 170a toward the front. As shown in FIG. 31, the guided portion 170b has a substantially rectangular shape, particularly a substantially square shape, in a cross section orthogonal to the extending direction of the guided portion 170b.

突出部170c係從本體部170a中之形成圓筒狀之外周面朝直徑方向突出而形成。在圖示之例中，突出部170c係沿著前後方向呈直線狀延伸。因此，被導引部170b之延伸方向及突出部170c之延伸方向係彼此呈平行。各突出部170係在周方向彼此具有等角度間隔而配置。在第35圖所示之例中，擋止構件170係具有二個突出部170c，各突出部170c彼此具有180度之角度間隔而配置。並不限定於此，擋止構件170係可具有一個突出部170c，亦可具有三個以上之突出部170c。 The protruding portion 170c is formed to protrude in the diameter direction from the cylindrical outer peripheral surface of the body portion 170a. In the example shown in the figure, the protrusion 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 protrusions 170c, and the protrusions 170c are arranged at an angular interval of 180 degrees. It is not limited to this, and the stopping member 170 may have one protrusion 170c, or may have more than three protrusions 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 on each of the rear end surface of the main body portion 170a and the front end surface of the guided portion 170b. In addition, the through hole 170d is not an essential component, and the stop member 170 may not have the through hole 170d. That is, the stopping member 170 may also 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 118h that guides the guided portion 170b of the stop member 170 in a forward and backward manner. The guide portion 118h extends in the front-rear direction in the piston 118 and is formed as a hole with an opening at the rear end surface of the piston 118. In the cross section of the guide portion 118 h orthogonal to the extending direction, the guide portion 118 h has a contour that forms a complementary shape with the guided portion 170 b of the stop member 170. That is, in the cross section of the guide portion 118h orthogonal to the extending direction, the guide portion 118h has a generally rectangular shape, especially a generally square-shaped outline. Thereby, the blocking member 170 is held in a manner capable of moving back and forth relative to the piston 118 and unable to rotate. In addition, the cross section of the guide portion 118h has a contour of 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 of 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 106h that restricts the movement of the protrusion 170c of the stopper member 170 is provided on the inner peripheral surface of the rotating body 106. The number of restriction portions 106h is the same as the number of protrusions 170c of the stop member 170. That is, in this modification, along the circumferential direction of the rotating body 106, the two restricting portions 106h are provided with an angular interval of 180 degrees from each other. The restriction portion 106h shown in the figure has a first groove portion 106i, and a plurality of second groove portions 106j positioned behind the first groove portion 106i and communicating with the first groove portion 106i. The first groove 106i extends linearly along the front-rear direction and has a certain width along the circumferential direction of the rotor 106. The second groove portion 106j is provided corresponding to the number of the segment 105f of the first cam slope 105e and the number of the segment 118e of the second cam slope 118d. That is, in this modification, three second groove portions 106j are provided with respect to one first groove portion 106i. The second grooves 106j extend linearly along the front-rear direction, and are arranged along the circumferential direction of the rotor 106. Each second groove portion 106j has a predetermined range at least on the front side (side close to the first groove portion 106i) and has a certain width along the circumferential direction of the rotor 106. The width of the second groove 106j along the circumferential direction of the predetermined range is set to the extent that the protrusion 170c of the stop member 170 can smoothly move back and forth in the second groove 106j. The other party From the viewpoint of appropriately suppressing the rotation of the friction body 125 when rubbing handwriting with the friction body 125, the circumferential margin between the second groove 106j and the protrusion 170c can be made as small as possible The one is 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, referring to FIGS. 34 and 35, a method of decolorizing the handwriting using the pressure-type writing instrument 201 of this modification will be described. Figure 34 is a diagram showing a state where the back end of the pressure pen 201 is facing downward in order to erase the color of the handwriting. Figure 35 shows the pressure pen in a cross section corresponding to the line XXXV-XXXV in Figure 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, with the rear end of the shaft tube 104 facing upward, the stopper member 170 is positioned on the front side by the action of gravity. At this time, the front end of the body portion 170a of the stopping member 170 or the front end of the guided portion 170b abuts against the piston 118, and at least the front portion of the guided portion 170b is positioned on the guide of the piston 118. Leading part 118h. In addition, the protruding portion 170c of the stopper member 170 is positioned in the first groove portion 106i of the restricting portion 106h of the rotor 106. Therefore, the protrusion 170c can move in the circumferential direction within the width of the first groove 106i. That is, the rotating body 106 is rotatable relative to the stop member 170 and the piston 118 within the range of the width of the first groove portion 106i. Thereby, the stop member 170 allows the rotation of the rotating body 106 in a state where the rear end of the shaft cylinder 104 faces upward. Therefore, with the rear end of the barrel 104 facing upward, referring to FIGS. 27A to 27C, as described above, by rotating the rotating body 106 to actuate the pressure adjusting mechanism 160, the application of the pen tool can be adjusted. Use the pressure of the ink composition (ink) 111.

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 used for writing tools When the handwriting produced by the object (ink) 111 is discolored (erased), as shown in FIG. 34, the user directs the friction body 125 downward. That is, the rear end of the shaft cylinder 104 is directed downward. Thereby, the stop member 170 moves backward by the action of gravity. At this time, the protruding portion 170c of the stopper member 170 enters one of the plurality of second groove portions 106j of the restricting portion 106h of the rotating body 106 (refer to FIG. 35). Specifically, in the second groove 106j corresponding to the indicated position (refer to FIG. 14) of the positioning mark 106f with respect to the pressure display portion 102h, a protrusion 170c enters. In other words, in the second groove 106j corresponding to the fitting position of the first cam protrusion 106b with respect to the segment 105f1 to 105f3 of the first cam slope 105e (refer to Figs. 28A to 28C), the protrusion 170c enters . Furthermore, in other words, there is a protrusion in the second groove 106j corresponding to the fitting position of the second cam protrusion 106d with respect to the second cam slope 118d segment 118e1 to 118e3 (refer to Figs. 28A to 28C) Section 170c enters. The width along the circumferential direction of the second groove portion 106j is smaller than the width along the circumferential direction of the first groove portion 106i, thereby preventing the rotation of the rotor 106 with the rear end of the shaft cylinder 104 facing downward. Therefore, when the rear end of the barrel 104 faces downward, and the protrusion 170c of the stop member 170 enters one of the plurality of second grooves 106j of the restricting portion 106h, the pen is applied by rotating the rotor 106 It is impossible to adjust the pressing force of the ink composition (ink) 111 for use. That is, at this time, when the rubbing body 125 is used to rub the handwriting, the rotating body 106 rotates together with the rubbing body 125, which prevents the pressure applied to the ink composition (ink) 111 for writing instruments from being inadvertently caused by the user. The situation is 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, the ink composition (ink) 111 for writing instrument is a thermochromic ink, and further includes: a friction body 125, which is provided at the rear end of the rotating body 106 for rubbing The handwriting of thermochromic ink can change the color of the handwriting by the friction heat generated at this time; and the stop member 170 allows the rotating body 106 to rotate with the rear end of the barrel 104 facing upward, and When the rear end of the shaft cylinder 104 faces downward, the rotation of the rotating body 106 is hindered.

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 upwards, by rotating the rotating body 106 to actuate the pressing force adjusting mechanism 160, the ink composition applied to the writing instrument can be adjusted ( Ink) 111 of pressure. On the other hand, when the rear end of the barrel 104 is directed downward and the handwriting is erased by the friction body 125, the friction of the handwriting by the friction body 125 can hinder the rotation of the rotor 106 and prevent the application of The pressing force of the ink composition (ink) 111 for writing instruments is changed inadvertently.
