め換え作業をなくし、手を汚すことなく、芯交
換、芯補充を行う、いわゆるカセツト式シヤープ
ペンシルが提案されている。
Recently, for example, the so-called cassette type cartridge, which stores writing leads as shown in Figure 4, has been replaced, eliminating the need to refill each lead individually and allowing the replacement and refilling of writing leads without getting your hands dirty. A mechanical pencil is suggested.
従来のカセツト式シヤープペンシルの芯カート
リツジ101は、先端にキヤツプ102が被嵌さ
れているだけであつて、シヤープペンシルの芯交
換・補給を行う際、まず、先端キヤツプ101を
取り外して廃棄し芯カートリツジ先端を開口した
状態でシヤープペンシルの外筒103内に嵌合し
ていた。 The lead cartridge 101 of a conventional cassette-type mechanical pencil only has a cap 102 fitted on the tip, and when replacing or replenishing the lead of a mechanical pencil, first remove the tip cap 101 and discard it, then replace the lead cartridge. It was fitted into the outer cylinder 103 of the sharp pencil with the tip open.
従つて、先端キヤツプ102の取り外し後、芯
カートリツジ101を少しでも下向き状態にする
と、芯104が芯カートリツジ101内から飛び
出してしまうという問題点があつた。 Therefore, if the lead cartridge 101 is turned downward even slightly after the tip cap 102 is removed, there is a problem in that the lead 104 will pop out from inside the lead cartridge 101.
そこで、芯交換等の際には、常に芯カートリツ
ジ101を上向きに保持した状態で気づかいしな
がら外筒103内への嵌合を行う必要があつた。 Therefore, when replacing the core, it is necessary to always hold the core cartridge 101 upward while carefully fitting it into the outer cylinder 103.
また、外筒103から芯カートリツジ101を
離脱させる場合も、芯カートリツジ101を少し
でも下向きにすると、芯カートリツジ101内か
ら飛び出し、外筒103内に残存してしまうとい
う問題点があつた。 Further, when removing the lead cartridge 101 from the outer cylinder 103, there was a problem that if the lead cartridge 101 was turned downward even slightly, it would fly out from inside the lead cartridge 101 and remain in the outer cylinder 103.
一方、従来のものでは、第5図示のように、芯
104を多数収納した芯カートリツジ101と、
この芯カートリツジ101を着脱自在に内嵌する
リードガイド105とが外筒103内に収納され

壁部106を設ける必要があり、この内方段差壁
部106によつて芯カートリツジ101が小径に
制約され、芯収納容量が小さくなるという問題点
があつた。また、上述のような内方段差壁部10
6を有する外筒103は押出成形が不可能なた
め、インジエクシヨン成形しなければならず、こ
の場合、金型が押出成形に比して高価になるとい
う問題点があつた。 On the other hand, in the conventional one, as shown in FIG. 5, a lead cartridge 101 storing a large number of leads 104,
A lead guide 105 into which this lead cartridge 101 is removably inserted is housed in the outer cylinder 103, so in order to pick up the remaining lead in the outer cylinder 103 with the lead cartridge 101, a tapered inner surface of the tip is provided. The chamfered portion 107 is necessary, and the outer cylinder 1
As shown in the figure, it is necessary to provide an inner stepped wall 106 with a stepped shape, and this inner stepped wall 106 restricts the lead cartridge 101 to a small diameter, reducing the lead storage capacity. There was a problem. Moreover, the inner step wall portion 10 as described above
Since the outer cylinder 103 having the number 6 cannot be extruded, it must be injected and extrusion molded.In this case, there is a problem that the mold is more expensive than extrusion molding.
この考案は上記問題点を解決するためになされ
たもので、芯交換・補給のために筆記具に弾着係

トリツジの開閉構造を提供することを目的とす
る。 This idea was made to solve the above problem, and the lead passage hole opens only when the writing instrument is engaged with the writing instrument for replacing or replenishing the lead, and closes when it is not engaged. To provide an opening/closing structure for a lead cartridge that prevents the lead from popping out when replacing the lead cartridge, eliminates waste parts, enables extrusion molding of a writing instrument outer cylinder, and increases the lead storage capacity of the lead cartridge. With the goal.

Inside, a core feed hole 65 is formed coaxially with the fitting hole 64 and has an inner diameter through which only one core 4 can be fed out. Further, a large-diameter step-shaped rear fitting hole 67 is provided inside the rear side of the rear outer cylindrical portion 63 . Inside the rear outer cylindrical portion 63, there is a tapered inner wall 68 that guides a core stopper piece 8A, which will be described later, when engaged, and a core stopper piece 8A guided by this tapered inner wall 68, which is engaged with the core stopper piece 8A, which will be described later. The engaging hole 6 opens the two core conduction holes 84A and 84B in a matching manner.

有する。 The opening/closing mechanism 8 is made of an elastically deformable material such as rubber or synthetic resin, and is fitted into the opening at the tip of the core cartridge 7 . As shown in FIGS. 2 and 3, this opening/closing mechanism 8 has a cylindrical shape that is fitted into the opening at the tip of the core cartridge 7 and has a first core passage hole 84A in its axial center. Main body 8B and
It is integrally connected to the tip side of this main body 8B in a bent shape,
A second core conduction hole 84A is located at a position that is different from the first core conduction hole 84A.

4B is the core 4 with the same core diameter (for example, 0.5mm only,
0.7mm only, 0.9mm only) or 4 cores with different core diameters
(for example, 0.5 mm and 0.7 mm). That is, when used only for cores 4 having the same core diameter, the core conduction hole 84
A and 84B are formed in a size that allows only one type of core 4, such as 0.5 mm, 0.7 mm, or 0.9 mm, to pass through when engaged with the lead guide 6. Next, if the cores 4 of different diameters (for example, 0.5 mm and 0.7 mm cores) are to be used together, the core conduction hole 84A,
84B is formed to have a matching opening size that allows conduction between any of the cores 4 when engaged with the lead guide 6.
Further, the opening positions of both holes 84A and 84B are closed at staggered positions so that conduction is impossible to any of the cores 4 when the engagement with the lead guide 6 is released.
次に動作について説明する。 Next, the operation will be explained.

係合時には開閉機構8は第2図示のように、本体
8Bおよび芯停止片8Aに開口された第1および
第2の芯導通孔84A,84Bは、芯導通不可能
に食い違い状態に位置している。 First, when the lead cartridge 7 and the lead guide 6 are not engaged, the opening/closing mechanism 8 opens the first and second lead conducting holes 84A and 84B opened in the main body 8B and the lead stopper piece 8A, as shown in the second figure. The cores are located in a mismatched state where conduction is impossible.

飛躍的に増大できる。 Next, when the lead cartridge 7 is removed from the lead guide 6 along with the opening/closing mechanism 8 in order to replace the lead or to check the lead midway from the state shown in FIG. The core stopper piece 8A moves to the second illustrated position, and the two core conduction holes 84A and 84B are closed in a staggered manner, making it impossible for the core 4 to conduct. Therefore, when the lead cartridge 7 is pulled out, there is no risk that the lead 4 in the lead cartridge 7 will come off from the opening at its tip and remain in the outer cylinder 1 or spill out of the outer cylinder 1. Furthermore, since there is no risk of residual core occurring, there is no need to provide a chamfer such as a taper on the inner surface of the tip of the core cartridge 7.
There is no manufacturing problem such as insufficient resin flow due to the thin inner wall of the tip when the core cartridge 7 is molded. Furthermore, unlike in the past, it is no longer necessary to provide an inner stepped wall inside the outer cylinder 1, so the outer cylinder 1 can be formed by inexpensive extrusion molding, and the diameter of the core cartridge 7 can also be reduced. It can be made thicker and the amount of core storage can be increased dramatically.

取られる。 In addition, if the core 4 remains across the core feed hole 65 and the two core conduction holes 84A and 84B of the opening/closing mechanism 8, this remaining core 4 will be used to connect the two cores when the opening/closing mechanism 8 is removed. Due to the elastic staggered closing action of the holes 84A, 84B, the lead 4 is chucked and pulled out through the lead conducting holes 84A, 84B.

い。 Therefore, after removing the lead cartridge 7,
If you pull it out from the lead passage holes 84A, 84B or push it into the lead cartridge 7, the remaining lead 4 may break when replacing the lead cartridge 7, or the broken lead 4 may There is no possibility that the lead guide 6 will become clogged.

作業を極めて簡単かつ容易に手際よく行える。 Then, when a new lead cartridge 7 is pushed in from the rear end of the outer cylinder 1, the lead stopper piece 8A of the opening/closing mechanism 8 is press-fitted into the fitting hole 69 of the lead guide 6 and snap-fitted, thereby causing the opening/closing mechanism 8 core conduction hole 84
A and 84B are opened to match and the core 4 can be supplied. When replacing the core cartridge 7, the two core conduction holes 84A and 84B are opened at different positions to prevent conduction of the core until the core stopper piece 8A is inserted into the fitting hole 69. There is no risk that the lead 4 in the lead cartridge 7 will pop out. In addition, since there is no need to hold the sharp pencil upside down and maintain the lead cartridge 7 upward during the replacement work, the replacement work of the lead cartridge 7 can be performed extremely simply, easily, and efficiently regardless of the orientation of the sharp pencil. .

As described above, according to this invention, the opening/closing mechanism elastically deforms so that the plurality of lead conduction holes open in alignment when engaged with the lead guide, and the plurality of lead conduction holes open in a staggered manner when not engaged. Therefore, there is no risk of the lead popping out when replacing the lead cartridge, and the chuck opening/closing mechanism closes when replacing the lead cartridge, allowing the lead remaining in the writing instrument to be removed. ,
The lead cartridge can be replaced very simply and easily without the risk of breakage of the remaining lead or clogging of the writing instrument due to the broken lead.
