2. Description of the Related Art Conventionally, a magnetic panel having a structure for displaying handwriting by using a magnetic pen with a writing magnet as a writing tip and using the magnetic field of the magnet is well known. Specifically, this magnetic panel has
a) For example, as disclosed in Japanese Examined Patent Publication No. 62-53359, a liquid storage chamber having a multi-cell structure is provided on the back side of the surface plate, and a dispersion liquid in which magnetic particles are dispersed in a colored dispersion medium is provided in the liquid storage chamber. By applying the magnetic pen magnetic field from the display surface side of the panel, the magnetic particles in the dispersion medium are attracted to the surface plate side for display, and the magnetic field of the erasing magnet is applied from the back side of the panel. A so-called magnetophoretic display panel that draws magnetic particles back to erase the handwriting,
b) Or, as disclosed in Japanese Examined Patent Publication No. 59-32796, a dispersion in which micro magnets in which the S pole side surface is colored in the first color and the N pole side surface in the second color are dispersed in the dispersion medium A magnetic panel containing a liquid in a liquid storage chamber, wherein the magnetic field of a magnetic pen is applied from the display surface side of the panel to invert the minute magnet and perform writing, and from the same display surface side, the writing is reversed. A so-called magnetic reversal type display panel that erases the handwriting by reversing the micro magnets by applying a magnetic field;
c) Further, as disclosed in WO2005 / 033790, the first magnetic material made of a high coercive force material and the second magnetic material made of a low coercive force material are mixed, and the surface on the S pole side is A magnetic panel in which a dispersion liquid dispersed in a dispersion medium containing a colorant having a color of a third color is accommodated in a liquid storage chamber in which a micro magnet colored in one color and colored on the N pole side surface in a second color Then, the magnetic field of a magnetic pen is applied from the display surface side of the panel to perform writing by moving or reversing / reversing the micro magnet, and further, the magnetic pole opposite to the time of writing is applied from the display surface side. The magnetic color can be changed by inverting the micro magnets that formed the above display, and erasing the handwriting by pulling the micro magnets back from the back side of the panel by the magnetic field of the erasing magnet. There is an inverted display panel.

こうした磁気パネル用の磁気ペンでは、分散媒中の表示用磁性体に異なる巾の磁界を作用させることで異なる線巾の筆跡を磁気パネルに表示させるために、異なる大きさの筆記用磁石を先端に装着した複数の磁気ペンを用いたり、あるいは前述の磁気反転型表示パネルや磁気泳動反転型表示パネルにおいては、微小磁石のS極側表面を磁気パネルの表面側へ引き寄せるためにN極を先端に向けた筆記用磁石を装着したものと、微小磁石のN極側表面を磁気パネルの表面側へ引き寄せるためにS極を先端に向けた筆記用磁石を装着した異なる2つの磁気ペンを必要としており、それぞれの磁気ペンを持ち替えて筆記する必要があった。   In such a magnetic pen for a magnetic panel, in order to display a handwriting with a different line width on a magnetic panel by applying a magnetic field of a different width to a magnetic body for display in a dispersion medium, a writing magnet of a different size is used at the tip. In the magnetic reversal display panel and the magnetophoresis reversal display panel described above, the N pole is used as the tip in order to draw the S pole side surface of the micro magnet toward the surface side of the magnetic panel. And two different magnetic pens equipped with a writing magnet with the south pole at the tip to attract the surface of the magnetic pole to the surface side of the magnetic panel. Therefore, it was necessary to change each magnetic pen and write.

前述のような磁気ペンを持ち替える手間を解消する方法として、一つの磁気ペン本体の両端に異なる筆記用磁石を装着する方法が考えつくが、やはり筆記時に磁気ペン本体の前後を逆に持ち替える煩わしさがあった。   As a method to eliminate the trouble of changing the magnetic pen as described above, it is conceivable to attach different writing magnets to both ends of one magnetic pen body. there were.

また磁気ペンでは、磁気パネルの表面を筆記用磁石で傷付けてしまわないようにすることが特に重要視されており、一般的には筆記用磁石の後ろに前後方向へ弾性変形を行うバネを配設して、過度な筆圧がパネル表面に掛からないようにする構造が多く採用されているが、前述のように磁気ペン本体の両端に筆記用磁石を装着する場合には、両端にあるそれぞれの筆記用磁石に対してバネを配設する必要があり、コストアップを招く虞がある。また、一方の筆記用磁石の後方に配したバネの弾性力と、他方の筆記用磁石の後方に配したコイルスプリングの弾性力とに、経時的な差が生じてしまい、その結果それぞれの筆記感が異なるという問題が生じる場合があった。
特公昭62−53359号公報 特公昭59−32796号公報 WO 2005/033790号公報
In magnetic pens, it is particularly important to avoid scratching the surface of the magnetic panel with a writing magnet. Generally, a spring that elastically deforms in the front-rear direction is placed behind the writing magnet. Many structures are used to prevent excessive writing pressure from being applied to the panel surface. However, when writing magnets are attached to both ends of the magnetic pen body as described above, It is necessary to dispose a spring with respect to the writing magnet, which may increase the cost. In addition, there is a difference over time between the elastic force of the spring arranged behind one writing magnet and the elastic force of the coil spring arranged behind the other writing magnet. There may be a problem that the feeling is different.
Japanese Examined Patent Publication No. 62-53359 Japanese Patent Publication No.59-32796 WO 2005/033790

本発明は、前述した磁気パネルへの使用を目的として、磁気ペン本体の一端側にて異なる少なくとの2つの筆記用磁石が使用可能なものとし、さらに筆記時において磁気パネルの表面に掛かる過度な筆圧を簡単な構造で緩和することができる磁気パネル用の磁気ペンを得ることである。   In the present invention, for the purpose of use in the magnetic panel described above, at least two different writing magnets can be used on one end side of the magnetic pen body, and moreover, the excessively applied to the surface of the magnetic panel at the time of writing. It is to obtain a magnetic pen for a magnetic panel that can relieve the writing pressure with a simple structure.

The present invention
“1. Magnetic pen for a magnetic panel in which writing is performed with a writing body in which a writing magnet is mounted in front of a magnetic panel in which a dispersion liquid in which a display magnetic body is dispersed in a dispersion medium is stored in a liquid storage chamber A projecting portion projecting from two sliding holes formed on a side surface of the magnetic pen main body, and a latching portion latched by a latch receiving member attached to the magnetic pen main body via an elastic member. And a first writing body with a first writing magnet attached to the front and a second writing body with a second writing magnet attached to the front different from the first writing magnet. Placed side by side inside the pen body and bounced back with a coil spring and housed, and the projection of either the first cursive or second cursive is advanced against the elastic force of the coil spring By doing so, the locking portion of the cursive body is engaged with the locking receiving member. The writing magnet attached to the front of the writing body is allowed to be projected from the tip opening of the magnetic pen body so that writing can be performed, and the elastic member holding the locking receiving member is elastically deformed during writing. This reduces the writing pressure applied to the magnetic panel.
2. 2. The magnetic pen for a magnetic panel according to claim 1, wherein the tip of the first writing magnet is an S pole and the tip of the second writing magnet is an N pole. "
It is.

さらに詳細には、筆記用磁石は先端と後端を異なる磁極とした一般的な永久磁石を用いることができる。その筆記用磁石は、筆記体の前方に凹部を形成して嵌着や接着させたり、あるいは樹脂にて筆記体を射出成形する際に、予め筆記用磁石を筆記体の前方部に鋳込むように装着してもよい。尚、本発明において、第一の筆記用磁石と異なる第二の筆記用磁石とは、第一の筆記用磁石の先端がS極である場合には第二の筆記用磁石の先端をN極として、分散媒中に分散した微小磁石に異なる磁界を作用できるもの、あるいは第一の筆記用磁石の大きさに対して第二の筆記用磁石の大きさを異ならせて、分散媒中の表示用磁性体に異なる巾の磁界を作用できるものことをいう。   More specifically, as the writing magnet, a general permanent magnet having different magnetic poles at the front end and the rear end can be used. The writing magnet is formed in such a manner that a concave portion is formed in front of the writing body to be fitted or adhered, or when the writing body is injection-molded with a resin, the writing magnet is previously cast into the front portion of the writing body. You may attach to. In the present invention, the second writing magnet, which is different from the first writing magnet, means that the tip of the second writing magnet is the N pole when the tip of the first writing magnet is the S pole. As shown in the above, the magnetic field can be applied to the micro magnets dispersed in the dispersion medium, or the size of the second writing magnet is different from the size of the first writing magnet. This means that magnetic fields with different widths can be applied to the magnetic material.

また、磁気ペン本体の摺動孔から突出するよう筆記体に設ける突出部は、少なくとも筆記体に装着した筆記用磁石が磁気ペン本体内に没入した状態の時において、磁気ペン本体に設けた摺動孔から突出する形状とする必要がある。また筆記体に設ける係止部は、筆記体の突出部を前方へ移動させた際に、軸筒本体内に配設した係止受部材に係止できる形状とする。具体的には、前後動する筆記体の軸心に対して直交する方向に略平行である係止部を形成することで、係止受部材に対して係止部が引っ掛かり易いものとなる。   In addition, the protruding portion provided on the writing body so as to protrude from the sliding hole of the magnetic pen body is a sliding portion provided on the magnetic pen body at least when the writing magnet attached to the writing body is immersed in the magnetic pen body. The shape needs to protrude from the moving hole. Moreover, the latching | locking part provided in a writing body is made into the shape which can be latched to the latching receiving member arrange | positioned in the axial cylinder main body, when the protrusion part of a writing body is moved ahead. Specifically, by forming a locking portion that is substantially parallel to a direction orthogonal to the axial center of the writing body that moves back and forth, the locking portion is easily caught by the locking receiving member.

また、筆記体の係止部を係止させる係止受部材は、コイルスバネやスポンジなどの弾性部材を介して磁気ペン本体の内部に装着するものとし、筆記体前方の筆記用磁石に過度な筆圧が掛かった際、つまり磁気パネルの表面に過度な筆圧が掛かった際には、係止受部材を保持した弾性部材が弾性変形して、磁気パネルの表面に掛かる筆圧を緩和できる構造とする。尚、弾性部材の弾性力の設定に関しては、磁気パネルに対する磁気ペンの筆記特性からして筆圧は全く関与しないので、パネル表面の強度に応じた設定を適宜行えばよい。またさらに、係止受部材に磁気ペン本体の後方から前方へ延びる壁面を設け、筆記体を前後動させる際に筆記体の表面を係止受部材の壁面に摺動させるようにすると、筆記体の動きをガイドする役目となり好ましい。本発明では、第一の筆記体および第二の筆記体が共に一つの係止受部材に係止する構造とするので、それに伴う弾性部材も一つでよい。従って、第一の筆記体および第二の筆記体の筆記感を同じに設定し易いものとなり、経時変化も同様となる。   In addition, the latch receiving member for latching the latching portion of the cursive body shall be attached to the inside of the magnetic pen body via an elastic member such as a coil spring or sponge, and an excessive brush should be applied to the curling magnet in front of the cursive body. When pressure is applied, that is, when excessive writing pressure is applied to the surface of the magnetic panel, the elastic member holding the latch receiving member is elastically deformed to reduce the writing pressure applied to the surface of the magnetic panel And In addition, regarding the setting of the elastic force of the elastic member, the writing pressure is not involved at all because of the writing characteristics of the magnetic pen with respect to the magnetic panel, and therefore the setting according to the strength of the panel surface may be appropriately performed. Furthermore, if the locking receiving member is provided with a wall surface extending from the rear to the front of the magnetic pen body and the surface of the writing body is slid on the wall surface of the locking receiving member when the writing body is moved back and forth, the writing body It is preferable because it serves as a guide for the movement of the camera. In the present invention, since the first writing body and the second writing body are both locked to one locking receiving member, only one elastic member is required. Therefore, it becomes easy to set the writing feeling of the first writing body and the second writing body to be the same, and the change with time is also the same.

また、第一の筆記体および第二の筆記体を磁気ペン本体の後方へ弾発するコイルスプリングは、磁気ペン本体の内部において各々の筆記体が挿通するよう配置すると共に、磁気ペン本体側に前端部を当接させ筆記体側に後端部を当接させることで、筆記体を磁気ペン本体の後方へ常時弾発できる。   In addition, the coil spring that repels the first writing body and the second writing body to the rear of the magnetic pen body is arranged so that each of the writing bodies is inserted inside the magnetic pen body, and the front end on the magnetic pen body side. The writing body can be constantly repelled to the rear of the magnetic pen main body by contacting the portion and bringing the rear end portion into contact with the writing body.

また、磁気ペン本体の先端開口部より筆記用磁石を突出させた筆記体の突出状態を解除するためには、第一の筆記体および第二の筆記体の双方の内側に係止解除用の膨出部を形成することで、係止受部材に係止している一方の筆記体の係止部に対し前進させた他方の筆記体の膨出部を当接させて、係止状態を解除できる構造となる。尚、この構造とする場合には、係止受部材に係止状態にある一方の筆記体に過度の筆圧が掛かって後退した際にも、一方の筆記体の係止部が他方の筆記体に形成した係止解除用の膨出部に接触してしまわない位置関係に設定することが肝要であり、筆記体の係止状態が不本意に解除されてしまうことがないものとする。   Moreover, in order to release the protruding state of the writing body in which the writing magnet protrudes from the opening of the tip of the magnetic pen body, it is necessary to release the lock on the inside of both the first writing body and the second writing body. By forming the bulging portion, the bulging portion of the other writing body that is advanced with respect to the locking portion of the one writing body that is locked to the locking receiving member is brought into contact, and the locked state is It becomes a structure that can be released. When this structure is adopted, even when one of the writing bodies in the locked state of the locking receiving member is retracted due to excessive writing pressure, the locking portion of one of the writing bodies is not It is important to set the positional relationship so as not to come into contact with the unlocking bulging portion formed on the body, and the locked state of the writing body is not unintentionally released.

また、筆記用磁石を除く他の筆記体構成を、樹脂材による射出成形にて一体で形成することにより、筆記体の部材点数が少なくなり、単純な構造で安価なものを提供することが可能となる。例えば、磁気パネルの微小磁石のS極側表面が赤色でN極側表面が黒色の場合には、先端がN極である筆記用磁石を装着した第一の筆記体の軸体を赤色の樹脂にて成形し、先端がS極である筆記用磁石を装着した第二の筆記体の軸体の色を黒色とすることで、それぞれの筆記体に形成された突出部の色にて突出させる筆記体の筆記色を使用者が判別できるものとなる。   In addition, by forming the cursive body structure other than the curling magnets integrally by injection molding with a resin material, it is possible to reduce the number of parts of the cursive body and provide a simple structure and an inexpensive one. It becomes. For example, when the S pole side surface of the micro magnet of the magnetic panel is red and the N pole side surface is black, the shaft body of the first writing body equipped with the writing magnet having the N pole at the tip is made of red resin. The shaft body of the second writing body, which is molded with the tip and the writing magnet having the S pole at the tip, is made black, so that it protrudes with the color of the protruding portion formed on each writing body. The user can discriminate the writing color of the cursive.

本発明の磁気パネル用の磁気ペンは、前述したような構造なので、磁気ペン本体の一端側にて異なる少なくとも2つの筆記用磁石が使用可能であり、さらに筆記時において磁気パネルの表面に掛かる過度な筆圧を簡単な構造で緩和することができるものとなった。   Since the magnetic pen for a magnetic panel according to the present invention has the structure as described above, at least two different writing magnets can be used on one end side of the magnetic pen body, and the magnetic pen is excessively applied to the surface of the magnetic panel during writing. The pen pressure can be relaxed with a simple structure.
