Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a writing instrument with a built-in memo paper, in which a cartridge-type memo storage body in which memo paper is wound is housed in a writing barrel.

[Conventional technology]

Conventionally, there have been writing instruments that have a lead inserted into a writing barrel, such as ballpoint pens and spare fountain pens, but when you want to write a memo, it is good to have memo paper on hand, but it is often not necessary. In many cases, there was no memo paper available.

For this reason, a writing instrument with a built-in memo pad has been proposed in Utility Model Application Publication No. 12108 of 1939 and other publications.

The writing instrument with built-in memo paper proposed in this bulletin is a short sharp pencil or fountain pen.
Cartridge type consisting of a spool in which a bottomed brush cylinder with a slit-shaped memo paper ejection port is connected in the axial direction, and the memo paper is wound around a winding portion having flange rings at both ends from the opening at the tip of the brush barrel. A memo storage body is inserted, a tail cap is fitted into the tip opening so as to be rotatable in forward and reverse directions, and an engagement shaft protruding from the tail cap is engaged with an engagement groove of the spool.

However, since this writing instrument with built-in memo paper has a bottomed writing barrel, it is troublesome to manufacture the writing barrel, and since the lead cannot be inserted into the spool of the cartridge-type memo storage unit, the spool is attached to the bottom of the writing barrel. Since an elastic stem is inserted into the shaft, the cartridge-type memo storage body does not rotate smoothly, making it difficult to attach the stem, increasing the number of parts, and adding a tail to the tip opening of the brush barrel. In order to fit the cap so that it can be rotated forward and backward, a cut groove is provided at the tip opening of the brush barrel, and the tail cap is elastically supported by the cut groove and fitted into the tip opening of the brush barrel. Because of this, there is a drawback that the tail cap tends to come off from the brush barrel.

For this reason, the head cap and a bottomed brush cylinder with a slit-shaped memo paper ejection opening formed in the axial direction are integrally formed, and a winding part having flange rings at both ends is connected from the tip opening of the brush cylinder. A cartridge-type memo storage body consisting of a spool wound with memo paper is inserted, a connecting tube is removably fitted into the opening at the tip, and a tail cap, which prevents the lead from being removed, is attached to the connecting tube in a non-rotatable but removable manner. Japanese Patent Laid-Open No. 162098/1987 proposes a writing instrument with a built-in memo pad, in which a spool rotating disc is disposed on a tail cap, and the outer end of a writing lead inserted into the spool is fitted onto the spool rotating disc. .

[The problem that the idea aims to solve]

However, in this writing instrument with built-in memo paper, the writing barrel is formed integrally with the head cap in a closed-bottom shape, making it very troublesome to manufacture the writing barrel. Because it fits into the tip opening, it easily comes off from the writing barrel, and furthermore, the memo paper is fed out or wound up by the spool rotating disk using the frictional engagement between the writing lead and the spool. Memo paper cannot be smoothly fed out and wound up, and the number of parts increases, the structure is complicated, and handling is inconvenient.

Therefore, the present invention solves the above-mentioned problems, and aims to provide a practical writing implement with built-in memo paper that has a small number of parts, a simple structure, easy handling, and practical use.

[Means for solving the problems]

In order to achieve the above-mentioned object, the present invention includes a brush barrel having a slit-shaped memo paper ejection opening in the axial direction, a head cap screwed onto one end of the brush barrel,
a connecting tube screwed onto the other end of the writing barrel; a writing lead inserted from the head cap to the writing barrel;
a cartridge-type memo storage body that is inserted through the writing lead and stored in the writing barrel body, and the cartridge-type memo storage body includes a spool having a winding portion with flange rings at both ends; The spool is formed to have approximately the same length as the distance between the inner end of the head cap screwed onto the writing barrel and the inner end of the connecting tube, and the spool has at least the connecting tube side of the spool. In the writing instrument with built-in memo paper, which has an engagement groove formed on the end face of the flange ring, an annular groove is formed on the outer periphery of the connecting tube, and a locking protrusion formed on the inner periphery of the tail cap is engaged with the annular groove, The present invention is characterized in that the tail cap is provided on the connecting pipe to prevent it from coming off and to be rotatable in forward and reverse directions, and an engagement shaft protruding from the tail cap is engaged with the engagement groove of the spool.

[Effect]

Therefore, when taking out the memo paper from the writing instrument with built-in memo paper of the present invention to write a memo,
First, rotate the tail cap in the normal direction, align the end of the memo paper wound on the spool with the memo paper ejection opening formed on the brush cylinder surface, and use the grip opening of this ejection opening to remove the edge of the memo paper. Simply pick out a portion, let the spool rotate to draw out the required amount, then place it on the take-out opening, cut it off, and use the cut-out portion as memo paper to write a memo using the writing instrument with the built-in memo paper.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 is a front view of the present invention applied to a ballpoint pen, FIG. 2 is a sectional view thereof, and FIG. 3 is an exploded perspective view thereof.

The ballpoint pen 1 with built-in memo paper is a pencil lead that includes a writing barrel 2, a head cap 3 screwed onto one end of the writing barrel, and a pen tip 4 inserted from the head cap 3 to the writing barrel 2. An ink tube 5 , a cartridge-type memo storage body 8 formed by winding memo paper 7 around a spool 6 which is rotatably housed in the writing barrel body 2 with the ink tube 5 inserted through the center hole, and the other end of the writing barrel body 2 . a connecting pipe 9 screwed onto the connecting pipe 9; and a tail cap 11 which is engaged with the connecting pipe 9 so as to be able to rotate forwardly and reversely.
and an engaging shaft 10 for rotating the cartridge-type memo storage body 8, which is protruded from the tail cap 11.

The writing barrel 2 has a take-out port 12 for taking out the memo paper 7 of the cartridge-type memo storage body 8.
It is formed by cutting out a straight line in the axial direction, that is, the longitudinal direction, of the writing barrel 2 to have a length approximately equal to the width of the memo paper 7. A linear cutter portion 13a for the memo paper 7 is formed on one axial edge of the ejection port 12, and a concave cutout is formed approximately in the middle of the other axial edge of the ejection port, so that the memo paper 7 can be clipped. A mouth 13 is formed.

Further, female threads 2a, 2a for screwing the male thread 3a of the head cap 3 and the male thread 9a of the connecting tube 9 are cut into the inner circumferential wall of one end and the other end of the writing barrel 2.

Spool 6 of the cartridge type memo storage body 8
is formed to have approximately the same length as the distance between the inner end of the head cap 3 screwed onto the writing barrel 2 and the inner end of the connecting tube 9, and is for winding the memo paper 7.
and a flange ring 6b integrally formed on both ends thereof,
6b, at least the tail cap 1
A cross-shaped engagement groove 14 is formed in the end face of the flange ring 6b on the first side.

The connecting tube 9 has a female thread 2 at the other end of the writing barrel 2.
A male screw 9a for screwing into the tail cap 11 and a fitting portion 9b of the tail cap 11 are formed, and an annular groove 9c is formed on the outer periphery at an intermediate position between them. and,
The tip of the male screw 9a is the flange ring 6b of the spool 6.
, and positions the spool 6.

The tail cap 11 has a protruding engagement shaft 10 having a cross-shaped cross section that engages the engagement groove 14 of the spool 6, and an engagement shaft 10 that engages the annular groove 9c of the connecting pipe 9 on the inner peripheral wall of the distal end of the tail cap 11. A plurality of locking protrusions 11 that fit together
A is provided.

This locking protrusion 11a engages with the annular groove 9c to prevent the tail cap 11 from coming off, and also enables forward and reverse rotation.
When rotating, it is guided by the annular groove 9c to ensure smooth rotation. This tail cap 11 is attached to the brush barrel 2.
When the spool 6 is rotated relative to the connecting pipe 9 screwed onto the spool 6, the spool 6 can be rotated via the engagement shaft 10 and the engagement groove 14.

Therefore, when taking out the memo paper 7, by pulling the memo paper 7 from the take-out port 12, the spool 6 rotates and the memo paper 7 can be taken out, but when the memo paper 7 is wound around the spool 6, The tail cap 11 may be rotated in the opposite direction to rotate the spool 6 in the direction in which the memo paper 7 is wound.

Note that the engagement groove 14 of the spool 6 and the engagement shaft 10 provided on the tail cap 11 may have any shape that allows them to engage with each other, and are not limited to a cross shape, for example, a fourth shape.
As shown in the figure, it can be square or even negative-shaped.

When assembling the brush barrel of this embodiment configured as described above, first, the cartridge-type memo storage body 8, which is made by winding the memo paper 7 around the spool 6, is stored into the brush barrel 2 from one end or the other end. Then, the head cap 3 into which the ink tube 5 has been inserted is screwed onto one end of the brush barrel 2, and the connecting tube 9, into which the tail cap 11 is engaged, is screwed onto the other end of the brush barrel 2, and the engagement shaft is 10 may be engaged with the engagement groove 14 of the spool 6.

When taking out the memo paper 7, first rotate the tail cap 11 in the normal direction so that the end portion 7a of the memo paper 7 wound around the spool 6 is visible from the ejection port 12, and then use your finger to pull the end portion 7a through the grip port 13. Pull out the memo paper 7 from the knob and take-out port 12, and after pulling it out to an appropriate length, place it on the cutter portion 13a of the take-out port 12 and cut it.
Make sure to write notes. The remaining note paper 7 can be completely stored by rotating the tail cap 11 in the opposite direction.

When the memo paper 7 runs out, the head cap 3 or connecting tube 9 is removed by screw means, the spool 6 with the memo paper 7 missing is taken out, a new cartridge-type memo storage body 8 is stored in its place, and the head cap 3 or connecting tube 9 is removed. The cap 3 or the connecting tube 9 may be screwed onto the writing barrel 2.

In addition, in this embodiment, an example in which the present invention is applied to a ballpoint pen is shown, but the present invention is not limited to this, but can be applied to all types of writing instruments such as spare fountain pens that have a lead inserted into a writing barrel. It is.

Further, the paper to be stored is not limited to colored memo paper, perfumed memo paper, and even memo paper, but also paper on which characters such as famous sayings and proverbs are printed can also be stored.

Furthermore, since the spool of memo paper is stored inside the writing barrel, it can store a considerable amount of memo paper. In other words, in the case of a ballpoint pen, the amount of memo paper that can be built into a normal ballpoint pen (approximately the same thickness as a pencil) is the same as a business card version (9cm) using thin type paper.
x 5.5 cm), it can store about 15 sheets inside and outside, fountain pen type can store around 25 sheets, and marker brush thickness can store about 35 sheets (about 2 m) or more, so
It can serve as a memo in case of emergency use.

[Effect of idea]

As mentioned above, the writing instrument with built-in memo paper of this invention has
A head cap is screwed onto one end of the brush barrel, which has a slit-shaped memo paper ejection opening in the axial direction, and a retainer is attached to the other end of the brush barrel to prevent the tail cap from slipping off in an annular groove. A cartridge-type memo storage body consisting of a spool with memo paper wound around a winding part having flanged rings at both ends, to which a connecting tube is screwed, is inserted into a writing lead inserted from the head cap to the writing barrel body. The spool is formed to have approximately the same length as the distance between the inner end of the head cap screwed onto the brush barrel and the inner end of the connecting tube, and at least the connection of the spool is inserted. Since the engagement shaft protruding from the tail cap is engaged with the engagement groove formed in the end face of the flange ring on the tube side, various effects can be obtained as described below.

When assembling a writing instrument with built-in memo paper, first insert the cartridge-type memo holder made of memo paper wound around a spool into the brush barrel from one end or the other, and insert the head cap into which the writing lead is inserted into one end of the brush barrel. Assembling is easy because all that is required is to screw the connecting tube into which the tail cap is engaged, to the other end of the writing barrel body, and to engage the engagement shaft into the engagement groove of the spool.

The cartridge-type memo storage body is stored rotatably around the pencil lead, and the spool of the cartridge-type memo storage body is stored at a distance between the inner end of the head cap screwed onto the writing barrel and the inner end of the connecting tube. Since the spool is positioned at the inner end of the head cap and the inner end of the connecting tube, the cartridge-type memo storage body rotates smoothly, and when taking out the memo paper, it is easy to First, rotate the tail cap in the normal direction, pinch the end of the memo paper wound on the spool with your fingers, pull out the memo paper from the ejection opening, pull it out to the appropriate length, then place it against the ejection opening and cut it to write a memo. Therefore, it is easy to take out the memo paper, and the remaining memo paper can be easily and completely stored by rotating the tail cap in the opposite direction.

When you run out of memo paper, remove the cap or connecting tube from the head of the brush cylinder body using a screw, take out the spool that has run out of memo paper, store a new cartridge-type memo storage body in its place, and connect the head cap or connecting tube. Since the tube only needs to be screwed onto the writing barrel, it is easy to remove the cap or connecting tube, and since the cartridge-type memo storage body can be taken in and out from either end of the writing barrel, replacement is easy.

Since the tail cap is engaged with the annular groove of the connecting tube so that it can be rotated forward and backward, the tail cap rotates smoothly and memo paper can be easily fed out and wound up.

Since the connecting tube in which the tail cap is engaged with the annular groove so as to be able to rotate forwardly and reversely in a locking manner is screwed onto the other end of the writing barrel, the connecting tube and the tail cap will not easily fall off from the writing barrel.

It has a small number of parts, a simple structure, easy handling, and is practical.
