Description

本発明は、筆記具を持ったときにはペン先が突出し、筆記具を離したときにはペン先が没入することができる筆記具に関する。   The present invention relates to a writing instrument in which the pen tip protrudes when the writing instrument is held and the pen tip can be immersed when the writing instrument is released.

従来から、筆記具を手で持つ動作によりペン先を突出し、非筆記時には、特別な操作をしなくても手から筆記具を離すことでペン先が没入する筆記具が提案されている。   2. Description of the Related Art Conventionally, there has been proposed a writing instrument in which the pen tip protrudes by an operation of holding the writing instrument by hand, and the pen tip immerses by removing the writing instrument from the hand when not writing, without performing a special operation.

特許文献１では、Ｕ字状の外ケース（２）の両側片（２ａ）間に筆記用リフィール（４）を備え、この筆記用リフィール（４）が挿入される挿入孔（９）を有する内ケース（３）が外ケース（２）の両側片（２ａ）間に摺動自在に嵌合する筆記具が提案されている。外ケース（２）と内ケース（３）間には、付勢手段（５）が設けられ、内ケース（３）を前方（筆記用リフィール（４）のペン先側）に付勢している。内ケース（３）は、カバー片（３ａ）の後端の係合段部（１１）が外ケース（２）に設けられる係止突部（１１）と当接することにより、前方への抜け止めがなされている。よって、非筆記時には筆記用リフィール（４）の先端（ペン先）は没入される。   In Patent Document 1, an inner portion having a writing refill (4) between both side pieces (2a) of a U-shaped outer case (2) and having an insertion hole (9) into which the writing refill (4) is inserted. A writing instrument has been proposed in which the case (3) is slidably fitted between both side pieces (2a) of the outer case (2). A biasing means (5) is provided between the outer case (2) and the inner case (3), and biases the inner case (3) forward (the pen tip side of the writing refill (4)). . The inner case (3) is prevented from coming forward by the engagement step (11) at the rear end of the cover piece (3a) coming into contact with the locking projection (11) provided on the outer case (2). Has been made. Therefore, the tip (pen nib) of the writing refill (4) is immersed when not writing.

一方、筆記時には、第１指（親指）と第３指（中指）により、内ケース（３）の側面（両カバー片（３ａ））を把持するとともに、第２指（人差し指）により、外ケース（２）の一方の側片（２ａ）を押さえ、かつ外ケース（２）の後端を、第２指（人差し指）の付け根付近に押し当てながら、内ケース（３）を外ケース（２）の両側片（２ａ）間に引き込ませる。この状態でペン先は突出し筆記可能となる。そして、この状態から筆記具（１）から手指を離すと、付勢手段（５）が内ケース（３）をペン先側へ付勢する付勢力により、再びペン先は没入されることとなる。   On the other hand, at the time of writing, the side surface (both cover pieces (3a)) of the inner case (3) is grasped by the first finger (thumb) and the third finger (middle finger), and the outer case is grasped by the second finger (index finger). While holding one side piece (2a) of (2) and pressing the rear end of the outer case (2) near the base of the second finger (index finger), the inner case (3) is moved to the outer case (2). It draws in between both side pieces (2a). In this state, the pen tip protrudes and writing is possible. Then, when the finger is released from the writing instrument (1) from this state, the pen tip is again immersed by the biasing force that biases the inner case (3) toward the pen tip side by the biasing means (5).

特開２００１−３１５４８７JP 2001-315487 A

上述の筆記具（１）においてペン先の突出状態を保ち筆記するためには、第２指（人差し指）の付け根付近に外ケース（２）の後端を押し当てている必要がある。一方、筆記具の持ち方としては、第１指（親指）と第２指（人差し指）で摘むようにして筆記具を持ち、第３指（中指）の第１間接付近で筆記具を支持するのが一般的である。この一般的な筆記具の持ち方と比較すると、特許文献１記載の筆記具は、筆記時において、常に第２指（人差し指）の付け根付近に外ケース（２）の後端が当接することを意識して筆記しなければならない。さらに、一般的な筆記具の持ち方と異なる持ち方を強いるものであるので、たとえメモ程度の短時間の筆記であっても使い難いものとなる。   In order to write with the pen tip protruding in the writing instrument (1) described above, it is necessary to press the rear end of the outer case (2) near the base of the second finger (index finger). On the other hand, it is common to hold a writing instrument by holding it with the first finger (thumb) and second finger (forefinger), and supporting the writing instrument near the first indirect position of the third finger (middle finger). is there. Compared with this general way of holding a writing instrument, the writing instrument described in Patent Document 1 is conscious that the rear end of the outer case (2) is always in contact with the vicinity of the base of the second finger (index finger) during writing. Must be written. Furthermore, since the holding method is different from a general writing tool holding method, even a short writing such as a memo is difficult to use.

本発明は、一端にペン先部を有する筆記芯と、前記筆記芯が挿通する貫通孔を有するカバー本体と、前記カバー本体を前記筆記芯に対して摺動自在にガイドするガイド手段と、前記カバー本体をペン先部側に付勢する付勢手段と、前記カバー本体のペン先部側への移動を規制する規制部と、前記カバー本体に対して押圧操作可能に形成された操作部と、前記カバー本体には、斜面状に形成される駆動斜面又は該駆動斜面と係合する係合部の何れか一方が設けられ、前記駆動斜面又は前記係合部の何れか他方は前記操作部に設けられ、前記操作部の押圧操作により前記カバー本体を前記筆記芯に対して前記筆記芯の他端側に移動させるように前記駆動斜面及び前記係合部を形成したことを特徴とする筆記具、である。   The present invention provides a writing core having a pen tip at one end, a cover body having a through-hole through which the writing core is inserted, guide means for slidably guiding the cover body with respect to the writing core, An urging means for urging the cover main body toward the pen tip portion; a restricting portion for restricting movement of the cover main body toward the pen tip portion; and an operation portion formed so as to be capable of pressing the cover main body. The cover main body is provided with either one of a drive slope formed in a slope shape or an engagement portion that engages with the drive slope, and the other of the drive slope and the engagement portion is the operation portion. A writing instrument, wherein the driving slope and the engaging portion are formed so as to move the cover body to the other end side of the writing core with respect to the writing core by a pressing operation of the operating portion. .

本発明によれば、一般的な筆記具の持ち方をするだけで、筆記芯を突出させることができる。すなわち、一般的な筆記具の持ち方において使用する第１指（親指），第２指（人差し指），第３指（中指）の何れか、又は２又は３の指により操作部を押圧操作すれば、付勢部材の付勢力に反してカバー本体がペン先部を露出する方向に移動するので、ペン先部が突出する。そして、指を離すと、付勢部材の付勢力によりペン先は没入される。よって、筆記時のみペン先部が突出し、筆記具から手を離すとペン先部が没入され、特にメモ的な短時間の筆記に好適な筆記具であるとともに、特異な持ち方を強いない、自然な持ち方で筆記することができる筆記具を構成することができる。   According to the present invention, the writing core can be protruded by simply holding a general writing instrument. That is, if the operation part is pressed with either the first finger (thumb), the second finger (forefinger), the third finger (middle finger), or the 2 or 3 fingers used in the general way of holding a writing instrument. The cover body moves in the direction in which the pen tip portion is exposed against the biasing force of the biasing member, so that the pen tip portion protrudes. When the finger is released, the pen tip is immersed by the urging force of the urging member. Therefore, the pen tip part protrudes only at the time of writing, and when you take your hand off the writing instrument, the pen tip part is immersed, and it is a writing tool that is particularly suitable for short memo-like writing, and does not have a unique holding method, natural A writing instrument that can be written in a holding manner can be configured.

以下、図面を参照しつつ本発明の実施例について説明する。なお、以下の説明において、前方向は、ペン先部（３ａ）側の方向を指す。   Embodiments of the present invention will be described below with reference to the drawings. In the following description, the forward direction refers to the direction on the pen tip (3a) side.

図１〜図４に、本発明にかかる筆記具１を示す。図１はペン先部３ａが没入した定常状態を示す筆記具１の縦断面図である。筆記具１は、開口側を前方側にした略Ｕ字状（換言すれば、二股状）に形成される操作本体２を有する。   1 to 4 show a writing instrument 1 according to the present invention. FIG. 1 is a longitudinal sectional view of the writing instrument 1 showing a steady state in which the pen tip 3a is immersed. The writing instrument 1 has an operation body 2 formed in a substantially U shape (in other words, a bifurcated shape) with the opening side on the front side.

操作本体２のＵ字状の底部である基部２ａは平板状に形成されている。基部２ａの両端からは、前方に向けて脚部２ｂが延在している。脚部２ｂの前方側端部には、操作部２ｃが連設されている。脚部２ｂと操作部２ｃの外面は、連続した平面状に形成されている。操作本体２は、その全体を合成樹脂材料により形成される。よって、脚部２ｂは弾性を有する。ゆえに、脚部２ｂは、操作部２ｃの押圧操作により弾性変形されるとともに、操作部２ｃの押圧力の解除により、弾性変形される前の形態に復帰することができる。   A base portion 2a which is a U-shaped bottom portion of the operation body 2 is formed in a flat plate shape. Legs 2b extend forward from both ends of the base 2a. An operation unit 2c is connected to the front side end of the leg 2b. The outer surface of the leg part 2b and the operation part 2c is formed in the continuous plane shape. The entire operation body 2 is formed of a synthetic resin material. Therefore, the leg 2b has elasticity. Therefore, the leg portion 2b is elastically deformed by the pressing operation of the operation portion 2c, and can be returned to the form before being elastically deformed by releasing the pressing force of the operation portion 2c.

脚部２ｂ間には、筆記芯３を支持するホルダー４が基部２ａから前方に向けて立設する。一方、筆記芯３は、一端側にペン先部３ａと、ペン先部３ａの後端に連設するインクタンク３ｂとにより構成されている。そして、ホルダー４の前方側端部に設けられた開口孔４ａには筆記芯３（インクタンク３ｂ）の後部が適度な嵌合力により圧入されている。ここで、適度な嵌合力とは、筆記芯３を支持しつつ、手動操作により筆記芯３を引き抜き、筆記芯３の交換をすることができる程度の嵌合力のことをいう。   Between the leg portions 2b, a holder 4 that supports the writing core 3 is erected forward from the base portion 2a. On the other hand, the writing core 3 is composed of a pen tip portion 3a on one end side and an ink tank 3b connected to the rear end of the pen tip portion 3a. And the rear part of the writing core 3 (ink tank 3b) is press-fitted with an appropriate fitting force into the opening hole 4a provided at the front end of the holder 4. Here, the appropriate fitting force refers to a fitting force that allows the writing core 3 to be pulled out and replaced by manual operation while supporting the writing core 3.

なお、本実施例においては、ペン先部３ａは金属製のボールペンチップである。インクタンク３ｂは、金属円筒パイプ材料にて形成されている。   In this embodiment, the pen tip 3a is a metal ballpoint pen tip. The ink tank 3b is formed of a metal cylindrical pipe material.

一方、筆記具１にはカバー本体５が設けられている。カバー本体５には、全体を略角筒状に形成されたカバー本体部５ａが設けられている。このカバー本体部５ａの両側面には、前方側の左右上下の４箇所に側板５ｂ、及び後方側の左右上下の４箇所に側板５ｃが設けられている（図４参照）。カバー本体５は、全体を合成樹脂材料により形成されている。   On the other hand, the writing instrument 1 is provided with a cover body 5. The cover main body 5 is provided with a cover main body portion 5a that is formed in a substantially rectangular tube shape as a whole. On both side surfaces of the cover body 5a, side plates 5b are provided at four locations on the front side, left and right and up and down, and side plates 5c are provided at four locations on the rear side, left and right and up and down (see FIG. 4). The cover body 5 is entirely formed of a synthetic resin material.

カバー本体部５ａには、長手方向前後を通じて丸孔状に貫通孔５ｄが設けられている。そして、この貫通孔５ｄには、筆記芯３が挿通される。より詳細には、ペン先部３ａと貫通孔５ｄとは接触していないが、インクタンク３ｂと貫通孔５ｄとは、摺動可能に形成される。換言すると、カバー本体５は、筆記芯３（インクタンク３ｂ）に対して前後方向（筆記芯３の長手方向）に摺動自在にガイドされているといえる。すなわち、筆記芯３（インクタンク３ｂ）と貫通孔５ｄにより、ガイド手段７が形成されているのである。   The cover main body 5a is provided with a through hole 5d in a round hole shape in the longitudinal direction. The writing core 3 is inserted into the through hole 5d. More specifically, the pen tip portion 3a and the through hole 5d are not in contact with each other, but the ink tank 3b and the through hole 5d are formed to be slidable. In other words, it can be said that the cover body 5 is slidably guided in the front-rear direction (longitudinal direction of the writing core 3) with respect to the writing core 3 (ink tank 3b). That is, the guide means 7 is formed by the writing core 3 (ink tank 3b) and the through hole 5d.

貫通孔５ｄの後方側には、バネ受け段部５ｅが円環状に設けられている。このバネ受け段部５ｅと、バネ受け段部５ｅと対向する基部２ａとの間には、ホルダー４及び筆記芯３（インクタンク３ｂ）に対して周設するように付勢手段であるコイルスプリング６が弾発して設けられている。よって、カバー本体５は、操作本体２に対して前方に付勢されている。   On the rear side of the through hole 5d, a spring receiving step portion 5e is provided in an annular shape. A coil spring which is an urging means between the spring receiving step portion 5e and the base portion 2a facing the spring receiving step portion 5e so as to be provided around the holder 4 and the writing core 3 (ink tank 3b). 6 is provided with a bullet. Therefore, the cover body 5 is biased forward with respect to the operation body 2.

カバー本体部５ａの上下の外面には、それぞれ駆動斜面５ｆが設けられている。この駆動斜面５ｆは、カバー本体部５ａの外面に対して鋭角をなして設けられている。そして、駆動斜面５ｆの前方側の端部には、係合段部５ｇが連設されている。係合段部５ｇは、駆動斜面５ｆから筆記芯３方向（軸心方向）へ向けて段部が形成されている。一方、駆動斜面５ｆの後方側の端部には、規制段部５ｈが連設されている。規制段部５ｈは、筆記芯３に対して外方向（軸心に対して外方向）に向けて段部が形成されている。   Drive slopes 5f are respectively provided on the upper and lower outer surfaces of the cover body 5a. The drive slope 5f is provided at an acute angle with respect to the outer surface of the cover body 5a. An engagement step portion 5g is connected to the front end portion of the drive slope 5f. The engaging step portion 5g is formed with a step portion from the drive slope 5f toward the writing core 3 direction (axial direction). On the other hand, a regulation step 5h is connected to the rear end of the drive slope 5f. The regulation step portion 5 h is formed with a step portion directed outward with respect to the writing core 3 (outward with respect to the axis).

一方で、操作本体２の操作部２ｃにおける内側面は、傾斜面２ｃ１を有し、カバー本体部５ａの外面に対して鋭角に設けられている。そして、傾斜面２ｃ１の後方側の端部は、脚部２ｂに連設するよう角状に形成される。この角状に形成された部分は、駆動斜面５ｆと係合する係合部２ｄとなる。   On the other hand, the inner side surface in the operation part 2c of the operation main body 2 has the inclined surface 2c1, and is provided at an acute angle with respect to the outer surface of the cover main body part 5a. The rear end portion of the inclined surface 2c1 is formed in a square shape so as to be connected to the leg portion 2b. The corner portion is an engaging portion 2d that engages with the drive slope 5f.

図１に示すペン先部３ａが没入される定常状態においては、係合部２ｄが規制段部５ｈと係合することにより、カバー本体５の前方側への付勢を規制している。   In the steady state in which the pen tip portion 3a shown in FIG. 1 is immersed, the urging of the cover body 5 toward the front side is restricted by the engaging portion 2d engaging with the restricting step portion 5h.

なお、側板５ｂ，５ｃは、それぞれ操作部２ｃ，脚部２ｂの側面と、近接又は接触して設けられている。よって、ガイド手段７（筆記芯３（インクタンク３ｂ），貫通孔５ｄ）により可能とされているカバー本体５の前後の摺動を補助的にガイドしている。これにより、操作本体２に対するカバー本体５の摺動時のブレを低減している。   The side plates 5b and 5c are provided close to or in contact with the side surfaces of the operation portion 2c and the leg portion 2b, respectively. Therefore, the guide means 7 (the writing core 3 (ink tank 3b), the through hole 5d) guides the sliding of the cover body 5 in the front-rear direction. Thereby, the blurring at the time of sliding of the cover main body 5 with respect to the operation main body 2 is reduced.

次に、本発明に係る筆記具１の動作を説明する。
図１に示す定常状態では、ペン先部３ａは没入している。換言すると、ペン先部３ａは、カバー本体５によりカバーされている。そして、筆記をするためには、第１指（親指）と第２指（人差し指）で、操作部２ｃの平坦な外面を挟むように（摘むように）して持つ。すると、脚部２ｂの弾性変形と相俟って、操作部２ｃがそれぞれ内側に押圧される。これにより、係合部２ｄは駆動斜面５ｆと当接する。係合部２ｄが駆動斜面５ｆと当接し、なおも操作部２ｃに内側への押圧力が掛ることで、コイルスプリング６の付勢力に抗して、係合部２ｄは駆動斜面５ｆ上を相対的に前方側に移動する。換言すると、駆動斜面５ｆが相対的に係合部２ｄに対して後方側に移動する。よって、カバー本体５は、操作本体２に対して後方側へ移動することとなる。 Next, the operation of the writing instrument 1 according to the present invention will be described.
In the steady state shown in FIG. 1, the pen tip portion 3a is immersed. In other words, the pen tip portion 3 a is covered by the cover body 5. In order to write, the first finger (thumb) and the second finger (forefinger) hold the flat outer surface of the operation unit 2c (pick). Then, coupled with the elastic deformation of the leg portion 2b, the operation portion 2c is pressed inward. Thereby, the engaging part 2d contacts the drive slope 5f. The engaging portion 2d abuts against the driving slope 5f, and the operating portion 2c is pressed inward, so that the engaging portion 2d is relatively moved against the biasing force of the coil spring 6 on the driving slope 5f. Move forward. In other words, the drive slope 5f moves to the rear side relative to the engaging portion 2d. Therefore, the cover body 5 moves to the rear side with respect to the operation body 2.

係合部２ｄが駆動斜面５ｆの前端に到達すると、駆動斜面５ｆ（カバー本体５）の後方移動が終了する。駆動斜面５ｆ（カバー本体５）の後方移動の終了と同時に、係合部２ｄは、係合段部５ｇと係合する。この状態がペン先部３ａが突出した状態（筆記状態）となる。図２にこのペン先部３ａ突出状態を示す。   When the engaging portion 2d reaches the front end of the drive slope 5f, the rearward movement of the drive slope 5f (cover body 5) ends. Simultaneously with the end of the rearward movement of the drive slope 5f (cover body 5), the engaging portion 2d engages with the engaging step portion 5g. This state is a state where the pen tip portion 3a protrudes (writing state). FIG. 2 shows the protruding state of the pen tip portion 3a.

筆記等して筆記具１の使用後に、第１指（親指）と第２指（人差し指）による操作部２ｃの押圧操作を解除すると、脚部２ｂの弾性力により操作部２ｃは外側へ移動（復帰）する。すると、係合部２ｄと係合段部５ｇの係合が解除されるとともに、コイルスプリング６の付勢力により、係合部２ｄが規制段部５ｈと係合する位置までカバー本体５が前方へ移動する。すなわち、ペン先部３ａが没入される定常状態（図１）へと復帰する。   After the writing instrument 1 is used for writing or the like, when the pressing operation of the operation unit 2c by the first finger (thumb) and the second finger (index finger) is released, the operation unit 2c moves outward (returns) by the elastic force of the leg 2b. ) Then, the engagement between the engagement portion 2d and the engagement step portion 5g is released, and the cover body 5 is moved forward to the position where the engagement portion 2d engages with the restriction step portion 5h by the biasing force of the coil spring 6. Moving. That is, it returns to the steady state (FIG. 1) in which the pen tip portion 3a is immersed.

このようにして、後端部のノックを押したりキャップを外す等の操作なく筆記具を使用することができるので、短時間のメモ書き等には好適である。さらには、通常筆記具を持つ操作の如く、第１指（親指）と第２指（人差し指）により摘むようにして筆記具を持つことができるので、違和感無く筆記具を使用することができる。   In this way, the writing instrument can be used without an operation such as pushing the knock at the rear end or removing the cap, which is suitable for short-time memo writing and the like. Furthermore, since the user can hold the writing tool by picking it with the first finger (thumb) and the second finger (forefinger) as in the case of the operation with the normal writing tool, the writing tool can be used without a sense of incongruity.

なお、本実施例のうち、係合段部５ｇを設けなくても、操作部２ｃの押圧操作によるカバー本体５の後方移動及びペン先部３ａを突出させ筆記することは可能である。しかし、この場合、第１指（親指）と第２指（人差し指）で筆記時も強めに操作部２ｃを押圧する必要がある。本実施例のように係合段部５ｇが設けられていれば、ある程度指の力を抜いても、係合部２ｄと係合段部５ｇが係合しているので、カバー本体５の前方への移動を補助的に規制することができる（筆記時移動規制補助手段８）。換言すれば、カバー本体５の前方への移動は操作部２ｃの押圧により規制されているが、さらに係合部２ｄと係合段部５ｇの係合により、補助的に、カバー本体５の前方への移動が規制されている。   In the present embodiment, even if the engagement step portion 5g is not provided, it is possible to write by causing the cover body 5 to be moved backward by the pressing operation of the operation portion 2c and the pen tip portion 3a to protrude. However, in this case, it is necessary to press the operation unit 2c with the first finger (thumb) and the second finger (forefinger) strongly even during writing. If the engagement step portion 5g is provided as in this embodiment, the engagement portion 2d and the engagement step portion 5g are engaged even if the finger force is removed to some extent. Can be supplementarily restricted (movement restriction assisting means 8 during writing). In other words, the forward movement of the cover main body 5 is regulated by the pressing of the operation portion 2c, but further, the front of the cover main body 5 is supplementarily supported by the engagement of the engagement portion 2d and the engagement step portion 5g. Movement to is restricted.

また、筆記芯３を交換する場合には、操作部２ｃを外側に若干押し広げることにより、係合部２ｄと規制段部５ｈの係合を解除して、カバー本体５を前方に引き抜く。すると、筆記芯３をホルダー４（開口孔４ａ）から引き抜き交換することができる。交換後、再び筆記芯３をカバー本体５の貫通孔５ｄに挿通し、係合部２ｄが規制段部５ｈに係合するまでカバー本体５を押し込めば、筆記芯３の交換操作は終了する。このとき、カバー本体部５ａ上の駆動斜面５ｆの後方に設けられ、カバー本体５ａ外面に対して鈍角状に形成された傾斜面５ｉと、操作部２ｃ内側面に形成された傾斜面２ｃ１が当接し、操作部２ｃを外側へ押し広げる変形を案内する。   When the writing core 3 is exchanged, the operation portion 2c is slightly pushed outward to release the engagement between the engagement portion 2d and the regulation step portion 5h, and the cover body 5 is pulled forward. Then, the writing core 3 can be pulled out from the holder 4 (opening hole 4a) and exchanged. After the replacement, the writing core 3 is again inserted into the through hole 5d of the cover main body 5 and the cover main body 5 is pushed in until the engaging portion 2d engages with the restriction step portion 5h. At this time, an inclined surface 5i provided behind the drive slope 5f on the cover body 5a and formed at an obtuse angle with respect to the outer surface of the cover body 5a, and an inclined surface 2c1 formed on the inner surface of the operation portion 2c It touches and guides the deformation that pushes the operating portion 2c outward.

以上の実施例１は、本発明の好適な実施形態であるが、本発明は上記実施例１に限定されるものではなく、他の構成においても実施することができる。   Example 1 above is a preferred embodiment of the present invention, but the present invention is not limited to Example 1 described above, and can be implemented in other configurations.

例えば、本実施例では操作部２ｃは２箇所設けられているが、例えば第２指（人差し指）のみで操作できるよう、１箇所に設けられるものとしてもよい。また、第１指（親指）、第２指（人差し指）、第３指（中指）で把持できるよう、操作部２ｃを３箇所設けてもよい。   For example, although the operation part 2c is provided in two places in a present Example, it is good also as what is provided in one place so that it can operate only with a 2nd finger (index finger), for example. Further, the operation unit 2c may be provided at three places so as to be grasped by the first finger (thumb), the second finger (index finger), and the third finger (middle finger).

さらに、本実施例では、操作部２ｃに係合部２ｄを設け、カバー本体５に駆動斜面５ｆを設けたが、これを逆にして、押圧操作する側（操作部）に駆動斜面、係合段部、規制段部を設け、対応するカバー本体に当該駆動斜面と係合する係合部を設けることもできる。   Furthermore, in this embodiment, the engaging portion 2d is provided in the operation portion 2c, and the drive slope 5f is provided in the cover body 5. However, the drive slope and the engagement on the side (operation portion) to be pressed are reversed. A stepped portion and a regulating stepped portion can be provided, and an engaging portion that engages with the driving slope can be provided on the corresponding cover main body.

本実施例ではカバー本体５や操作本体２全体を角筒状に形成したが、円筒状等の任意の形態を採ることができる。   In the present embodiment, the cover main body 5 and the entire operation main body 2 are formed in a rectangular tube shape, but an arbitrary form such as a cylindrical shape can be adopted.

本実施例では、ガイド手段７として、カバー本体５の貫通穴５ｄが筆記芯３のインクタンク３ｂと摺動して、前後に移動可能に形成されているが、他の実施例としては、ガイドレールとこれにガイドされる摺動突起等をカバー本体５及び操作本体２にそれぞれ設けてもよい。ただし、本実施例のように、インクタンク３ｂと貫通孔５ｄによるカバー本体５のガイドであれば、ガイドレール等を設けるよりも部材の成形や組立等の面で製造コストが低く好適である。特に、本実施例では、インクタンク３ｂを金属製としていることから、堅牢性があるので、ガイドを確実に行うことができる。しかし、インクタンク３ｂを比較的硬質な合成樹脂材料等の他の材料とすることもできる。   In this embodiment, as the guide means 7, the through hole 5 d of the cover body 5 slides with the ink tank 3 b of the writing core 3 so as to be movable back and forth. A rail and sliding projections guided by the rail may be provided on the cover main body 5 and the operation main body 2, respectively. However, if the cover body 5 is guided by the ink tank 3b and the through-hole 5d as in this embodiment, the manufacturing cost is lower in terms of molding and assembly of the member than the provision of the guide rail and the like. In particular, in this embodiment, since the ink tank 3b is made of metal, the ink tank 3b is robust, so that the guide can be reliably performed. However, the ink tank 3b can be made of other materials such as a relatively hard synthetic resin material.

なお、筆記芯３はボールペンに限定されるものではなく、シャープペンシル、マーキングペン等各種筆記芯を適用することもできる。   The writing core 3 is not limited to a ballpoint pen, and various writing cores such as a mechanical pencil and a marking pen can be applied.

さらに、本実施例では、カバー本体５の前方への規制は、係合部２ｃと規制段部５ｈの係合によるが、これとは別に、例えば操作本体２とカバー本体５に係合部、被係合部を設けて、規制部を構成することもできる。すなわち、カバー本体５の前方への移動を規制する手段が講じられていればよい。   Further, in the present embodiment, the forward restriction of the cover body 5 is based on the engagement of the engagement portion 2c and the restriction step portion 5h. Separately, for example, the engagement portion between the operation body 2 and the cover body 5; It is also possible to configure the restricting portion by providing the engaged portion. That is, it is only necessary to provide a means for restricting the forward movement of the cover body 5.

また、本実施例では、操作部２ｃは脚部２ｂと連設しているが、コイルスプリング等を利用して、個別に操作部を形成してもよい。すなわち、駆動斜面に対する押圧操作が可能で、押圧解除により復帰する構成であればよい。   In the present embodiment, the operation portion 2c is connected to the leg portion 2b. However, the operation portion may be formed individually using a coil spring or the like. In other words, any configuration may be used as long as it can perform a pressing operation on the driving slope and can be restored by releasing the pressing.

本実施例では、付勢手段としてコイルスプリング６を用いたが、その他の付勢手段、例えば板バネ、エアダンパ等種々のものを用いることができる。   In this embodiment, the coil spring 6 is used as the urging means, but other urging means such as a plate spring and an air damper can be used.

また、上記の筆記時にカバー本体５が前方へ移動してしまうことを規制する手段（筆記時移動規制手段８）は、本実施例では係合部２ｄと係合段部５ｇとにより形成したが、他の実施例としては以下のものが挙げられる。例えば、傾斜面２ｃ１と、筆記時（ペン先３ａ突出時、図２参照）に傾斜面２ｃ１がカバー本体５ａと当接する面の両方又は何れか一方の面を荒く仕上げたり、熱可塑性エラストマーやゴム材料により形成することもできる。この場合、傾斜面２ｃ１と、傾斜面２ｃ１と筆記時に当接するカバー本体５ａの外面との間に摩擦力が発生するので、筆記時にある程度指の力を抜いても、カバー本体５の前方への移動を規制することができる。   The means for restricting the cover body 5 from moving forward during writing (the movement restricting means 8 during writing) is formed by the engaging portion 2d and the engaging step portion 5g in the present embodiment. Other examples include the following. For example, the inclined surface 2c1 and / or the surface of the inclined surface 2c1 that comes into contact with the cover body 5a when writing (when the pen tip 3a protrudes, see FIG. 2) are roughly finished, or a thermoplastic elastomer or rubber is used. It can also be formed of a material. In this case, since a frictional force is generated between the inclined surface 2c1 and the outer surface of the cover body 5a that contacts the inclined surface 2c1 during writing, even if a finger is partially removed during writing, Movement can be regulated.
