14の順に小さくなっている。Here, the elastic force of the first to third elastic bodies is the largest in the third elastic body 15, and then decreases in the order of the first elastic body 6 and the second elastic body 14.
上記芯保護用のキャップ3は第1図示のように、外筒1
とほぼ同径の筒状をなすキャップ本体19と、このキャ
ップ本体19の後端に設けられた上記芯出−足保持機構
2を有する。The cap 3 for protecting the core is attached to the outer cylinder 1 as shown in the first diagram.
The cap body 19 has a cylindrical shape having approximately the same diameter as the cap body 19, and the centering foot holding mechanism 2 provided at the rear end of the cap body 19.
上記キャップ本体19はその内壁に上記内筒5の指先の
ノック用のノック溝5aと係合するノック用段部19
aが設けられ、キャップ装着を行うことによって内筒5
をノックできるように形成されている。The cap body 19 has a knock step portion 19 on its inner wall that engages with the knock groove 5a of the fingertip of the inner cylinder 5.
a is provided, and by attaching the cap, the inner cylinder 5
It is formed so that it can be knocked.
また上記芯出−足保持機構2はキャップ本体19の後端
に軸方向に移動調整可能に、例えば螺着された調整部2

部材22と上記調整部20との間に弾着され、一端で基
当接部材を一体係止した第4の弾性体23とを有する。Further, the centering and foot holding mechanism 2 is provided with an adjusting section 2 screwed onto the rear end of the cap body 19 so as to be able to move in the axial direction.
0, a base abutting member 22 that comes into contact with the core 21, and a fourth elastic body that is elastically attached between this base abutting member 22 and the adjustment section 20 and integrally locks the base abutting member at one end. 23.
次にこの考案の動作(2ついて説明する。Next, the operation (2) of this invention will be explained.
筆記に際して又は筆記中において芯21の突出させる手
段として2つの方法があることがこの考案の動作の特徴
である。A feature of the operation of this device is that there are two methods for protruding the lead 21 during or during writing.
第1の手段は通常のようにノック部10をノック動作す
ればよい。The first means is to perform a knocking operation on the knocking part 10 as usual.
即ち、上述のように内筒5は外筒1の内壁段部1aによ
って前進方向の摺動が規制されているので、ノック動作
によって、芯パイプ8が内筒5に対して前進方向に移動
を行い、芯送り出し機構9によって芯21が突出される
こととなる。That is, since the sliding movement of the inner cylinder 5 in the forward direction is restricted by the inner wall stepped portion 1a of the outer cylinder 1 as described above, the core pipe 8 is prevented from moving in the forward direction with respect to the inner cylinder 5 due to the knocking action. Then, the core 21 is ejected by the core feeding mechanism 9.
第2の手段としては、特に筆記中には極めて便利であり
、外筒1を握持したままで、2本の指先で内筒5の指先
ノック用のノック溝5aを挟持し、後方に向けて引張移
動させれば、内筒5は第1の弾性体6の付勢力に抗して
後退するが、芯パイプ8はノック受台16が天ビス4に
よって係止されるために後退方向の移動が規制されるの
で、通常のノック動作と同様に芯21が先具7より突出
することとなる。The second method, which is extremely convenient especially while writing, is to hold the knock groove 5a of the inner cylinder 5 with two fingertips while gripping the outer cylinder 1, and point it backward. When the inner cylinder 5 is pulled and moved, the inner cylinder 5 moves backward against the biasing force of the first elastic body 6, but the core pipe 8 moves in the backward direction because the knock holder 16 is locked by the crown screw 4. Since the movement is restricted, the lead 21 will protrude from the tip 7 in the same way as in a normal knocking operation.
従って、この方法によれば、筆記時に外筒1の握りを持
ち変えることなく極めて容易に芯21の突出を行うこと
かで゛きる。Therefore, according to this method, the lead 21 can be protruded very easily without changing the grip of the outer cylinder 1 when writing.
さらに指先によるノック動作の他に芯保護用のキャップ
3を装着することによっても芯21を突出させることか
で゛きる。Furthermore, in addition to the knocking action with the fingertip, the lead 21 can also be made to protrude by attaching the cap 3 for protecting the lead.
即ち、筆記終了時にキャップ3を外筒1に嵌合させると
、キャップ本体19のノック用段部19 aは内筒5の
ノック溝5aに係合するので、内筒5および芯パイプ8
は上述の指先によるノック動作と同じ動作を行い芯21
が先具7より突出することとなる。That is, when the cap 3 is fitted into the outer cylinder 1 at the end of writing, the knock step 19a of the cap body 19 engages with the knock groove 5a of the inner cylinder 5, so that the inner cylinder 5 and the core pipe 8
performs the same knocking action with the fingertips described above and presses the core 21.
will protrude from the tip 7.
従ってこの方法では、筆記に際してキャップ3を取り外
すことによって、常に芯21が突出しているので、即座
に筆記を行うことができる。Therefore, in this method, by removing the cap 3 when writing, the lead 21 always protrudes, so that writing can be performed immediately.
ここで、このキャップ3には芯出−足保持機構2が装備
されているので、キャップ装着時に芯21が先具7から
出過ぎていても、芯出−足保持機構2の基当接部材22
は芯21の先端に押圧され、第4の弾性体23の付勢力
に抗して退没する。Here, since this cap 3 is equipped with the centering-foot holding mechanism 2, even if the lead 21 protrudes too much from the tip 7 when the cap is attached, the base abutting member 2 of the centering-foot holding mechanism 2
is pressed by the tip of the core 21 and retreats against the biasing force of the fourth elastic body 23.
この退没動作は上述のノック動作によってリードチャッ
ク11による芯21の喰込みが解除されるまで行なわれ
る。This retraction operation is continued until the lead chuck 11 is released from biting into the core 21 by the above-mentioned knocking operation.
そしてリードチャック11による芯21の喰込みが解除
されると、今度は逆に芯21は第4の弾性体23に付勢
された基当接部材22によって所定の長さまで内筒5内
に押圧移動する。When the lead chuck 11 releases the lead 21, the lead 21 is then pressed into the inner cylinder 5 to a predetermined length by the base contact member 22 urged by the fourth elastic body 23. Moving.
従って、キャップ装着時に芯21が先具7から出過ぎて
いても、芯出−足保持機構2によって芯21の折損、芯
すべり等は全く起こさず、しかも常に筆記に適する芯突
出量が保持できる。Therefore, even if the lead 21 protrudes too much from the tip 7 when the cap is attached, the lead 21 will not break or slip at all due to the centering-foot holding mechanism 2, and the amount of lead protrusion suitable for writing can always be maintained.
さらに芯出−足保持機構2には調整部20が設けられて
いるので、必要に応じて芯21の突出量を変更したい場
合には調整部20を軸方向に移動させれ1ば、第4の弾
性体23に係止された基当接部材22と先具7との間の
距離が変更できるので、上述の動作によって芯21の突
出量を変更することができる。Furthermore, since the centering and foot holding mechanism 2 is provided with an adjusting section 20, if it is desired to change the amount of protrusion of the core 21 as required, the adjusting section 20 can be moved in the axial direction. Since the distance between the base abutting member 22 locked to the elastic body 23 and the tip 7 can be changed, the amount of protrusion of the core 21 can be changed by the above-mentioned operation.
また第2図は他の実施例を示し、第1の弾性体6の位置
を変更した場合の実施例である。FIG. 2 shows another embodiment, in which the position of the first elastic body 6 is changed.
クッション間隔Aを設けたノック受台16の天ビス4と
の間に第1の弾性体6を弾着したものであり、この第1
の弾性体6の付勢力によって内筒5および芯パイプ8の
全体を前進方向に付勢し、第1図の実施例と同様の効果
が得られる。A first elastic body 6 is landed between the knock holder 16 and the crown screw 4 with a cushion interval A, and this first
The entire inner cylinder 5 and core pipe 8 are urged in the forward direction by the urging force of the elastic body 6, and the same effect as the embodiment shown in FIG. 1 can be obtained.
以上記載のようにこの考案の筆記具によれば、芯の突出
をノック部のノック動作の外に内筒のノック動作によっ
ても行え、必要に応じていずれかの手段を選択すればよ
い。As described above, according to the writing instrument of this invention, the protrusion of the lead can be performed not only by the knocking action of the knocking part but also by the knocking action of the inner cylinder, and any one of these methods may be selected as necessary.
特に内筒のノック動作は指先によって行なえるので、筆
記中において外筒の握りを持ち変えないで芯の突出を行
うことができる極めて優れた実用的効果がある。In particular, since the knocking action of the inner cylinder can be performed with the fingertips, the lead can be ejected without changing the grip of the outer cylinder during writing, which has an extremely excellent practical effect.
尚、この実施例ではシャープペンシルについて説明した
が、これに限定されることなく、ノック式のボールペン
等ノック式の筆記具全般に使用することができる。In this embodiment, a mechanical pencil has been described, but the present invention is not limited to this, and can be used for any type of writing instrument such as a knock-type ballpoint pen.
