Description

【0001】
【発明の属する技術分野】
本発明は、両面式磁性体反転表示パネルに関する。
【0002】
【従来の技術】
磁性体反転表示パネルは従来公知であり、例えば特公昭59−32796号公報等にも記載されている。ところで、従来構造の磁性体反転表示パネルを図を用いて簡単に説明すると、図3に示すように、磁性体反転表示パネル100aは、透明な表面板2及び裏面板3間に隔壁4を配置して、その間に複数の液体収容室5を形成している。また、液体収容室5に収容した分散液体6は、表示用磁性体7を分散媒と増稠剤とからなる液体8中に分散した降伏値を有する液体であり、表示用磁性体7は緑色に着色されたS極側表面部分と白色に着色されたN極側表面部分とを有している。
【0003】
前記の磁性体反転表示パネル100aに表示情報を書き込むには、図3に示すように、例えば、透明な表面板2が白色(N極側表面部分)の状態で、ペン形状の磁気ペン9の前方部に設けた先端部が磁性体反転磁極としてN極を有する磁極部10を、透明な表面板2に接触した状態で矢印T方向へ移動させると、磁力Fにより表示用磁性体7の緑色(S極側表面部分)が線状に透明な表面板2側へ配置される。この場合、白色(N極側表面部分)の表面板2側に緑(S極側表面部分)の表示線が表示される。
【0004】
前記白色の背景に緑(S極側表面部分)の表示が行われている表面板2を白色に戻す場合には、磁気イレーザー11を使用する。磁気イレーザー11は平べったい磁石であり、S極12とN極13の磁性体反転磁極を有している。磁気イレーザー11のS極12側を、磁性体反転表示パネル100aの表面板2の緑(S極側表面部分)の表示に接触させると、表示用磁性体7の白色(N極側表面部分)が透明な表面板2側に配置されて白色となる。
【0005】
ところで最近、筆記情報量を多くするために、パネルの両面に筆記を行うことができるものが望まれている。図4は、2枚の磁性体反転表示パネル100a,100bを互いの裏面側が向き合うように接着剤14で固着して、両面に筆記を行うことができるようにした両面構造のものである。
【0006】
【発明が解決しようとする課題】
しかしながら、前述した通り磁性体反転表示パネル100aは、表示用磁性体7を除くと他の構造体は非磁性体であるので、例えば磁気ペン9の磁極部10を磁性体反転表示パネル100aの表面板2に接触した状態で矢印T方向へ移動させると、磁気ペン9の磁力Fにより、磁性体反転表示パネル100aの表面板2側に、白色(N極側表面部分)を向けて整列していた表示用磁性体7を反転させて緑色(S極側表面部分)の筆記線を描くのと同時に、磁性体反転表示パネル100bの透明な表面板2側に緑色(S極側表面部分)を向けて整列していた表示用磁性体7を反転してしまい、磁性体反転表示パネル100bの表面板2に不要な白色(N極側表面部分)の筆記線が描かれてしまうという問題があった。
【0007】
本発明は前述の事情に鑑み、一方の磁性体反転表示パネルの表面板側から筆記を行う際に、他方の磁性体反転表示パネルに影響を与えることのない両面式磁性体反転表示パネルを提案することを目的とする。
【0008】
【課題を解決するための手段】
次に、前記課題の解決をするために案出した本発明を説明する。
「1.S極及びN極を有しS極側表面部分とN極側表面部分とを異なる色に着色した表示用磁性体と、該表示用磁性体を分散媒と増稠剤とを主成分とする降伏値を有する液体中に分散した分散液体を収容した複数の液体収容室の表面側に、透明な表面板を配置した第一の磁性体反転表示パネルと第二の磁性体反転表示パネルとを、一枚の鉄板の両面に互いの裏面側が向き合うように配置したことを特徴とする。
2.前記第一の磁性体反転表示パネル及び第二の磁性体反転表示パネルが、透明な表面板と裏面板との間にハニカム構造の隔壁を固着して該隔壁の壁面間を前記液体収容室としたことを特徴とする。
3.前記第一の磁性体反転表示パネル及び第二の磁性体反転表示パネルが、透明な表面板と裏面板との間にハニカム構造の隔壁を固着して該隔壁の壁面間を前記液体収容室とすると共に、前記第一の磁性体反転表示パネルと第二の磁性体反転表示パネルとを、前記一枚の鉄板の両面に互いの裏面板が向き合うように固着して一体としたことを特徴とする。」
【0009】
本発明で、第一の磁性体反転表示パネルと第二の磁性体反転表示パネルとを、一枚の鉄板の両面に互いの裏面側が向き合うように配置するのは、第一の磁性体反転表示パネルの表面板側から磁気ペンの磁力で表示用磁性体を動かして筆記を行う際に、第一の磁性体反転表示パネルと第二の磁性体反転表示パネルとの間の鉄板が磁力を吸収するので、第二の磁性体反転表示パネルの表示用磁性体が動かされず、第二の磁性体反転表示パネルへ影響を与えることがないためである。
【0010】
また、筆記を行う側の磁性体反転表示パネルにおいても、本発明ではパネルの裏側に鉄板があるため、磁極から生じる磁力線が磁極近傍の鉄板に引き寄せられパネル面に対して直交し易くなり、結果として、磁気ペンによる筆記線の輪郭が整い、また、磁気イレーザーによる消去がきれいに行なえるという相乗の作用効果がある。尚、1枚の鉄板を2枚の磁性体反転表示パネルで共用するのでコスト的に優れ、重量が軽減できるので、例えば、複数枚の両面式磁性体反転表示パネルを重ねて綴じて、ノートのような形態にして、さらに多くの筆記を可能にすると共に、携行を容易にすることが可能である。
【0011】
また、第一の磁性体反転表示パネル及び第二の磁性体反転表示パネルが、透明な表面板と裏面板との間にハニカム構造の隔壁を固着して隔壁の壁面間を液体収容室とするのは、表面板と裏面板とハニカム構造の隔壁とを動かぬように固定することで、パネルの剛性を高めるためであり、さらに、第一の磁性体反転表示パネルと第二の磁性体反転表示パネルとを、一枚の鉄板の両面に互いの裏面板が向き合うように固着して一体とするのは、第一の磁性体反転表示パネルと第二の磁性体反転表示パネルとを一枚の鉄板を介して一体構造とすることにより、両面式磁性体反転表示パネルとしての強度が相乗的に向上し、合板やパーティクルボード等の補強板をあてがわなくとも強度を得ることができるためである。
【0012】
また、ハニカム構造の隔壁を透明な表面板と裏面板とに固着する方法としては、接着剤を用いたり、熱溶着による手段を用いることが可能であり、固着力が液体収容室内に収容する分散液体の影響を受けない手段であるなら特に限定はない。また、裏面板と鉄板とを固着する方法としては、接着剤や両面粘着テープ等によりはり合わせて固着する手段を用いることができる。尚、接着剤及び両面粘着テープは、裏面板及び鉄板を全面的に展着すればより固着強度の高いものとなるが、裏面板と鉄板とが互いに容易に剥がれないものであれば部分的な展着でもかまわず、少なくとも板の四隅が固着してあれば双方が一体構造となるので良い。
【0013】
【発明の実施の形態】
本発明を理解しやすいように図面を参照しながら、本発明の実施の形態例を説明する。図1は、本実施の形態の両面式磁性体反転表示パネルに磁気ペンで筆記を行っている状態の断面図である。図1において、両面式磁性体反転表示パネル1は、第一の磁性体反転表示パネル1aと第二の磁性体反転表示パネル1bと鉄板15とからなる構造としてある。第一の磁性体反転表示パネル1a及び第二の磁性体反転表示パネル1bは、透明な表面板2及び裏面板3間にハニカム構造の隔壁4を接着剤(図示せず)により固着して配置し、隔壁4の壁面間を複数の液体収容室5としてある。また、液体収容室5には、分散媒と増稠剤とからなる液体8中に表示用磁性体7を分散した降伏値を有する分散液体6を収容してある。表示用磁性体7はS極側表面部分を緑色に着色し、N極側表面部分を白色に着色してある。
【0014】
尚、本実施の形態では図1に示す通り、第一の磁性体反転表示パネル1aと第二の磁性体反転表示パネル1bとは、鉄板15の両面に互いの裏面板3が向き合うように接着剤14で固着して一体としてあるので、磁気ペン9を用いて第一の磁性体反転表示パネル1aの表面板2側から筆記を行う場合には、磁極10から生じる磁力Fにより、第一の磁性体反転表示パネル1aの表面板2側に、白色(N極側表面部分)を向けて整列していた表示用磁性体7を反転させて緑色(S極側表面部分)の筆記線を描くことができると共に、磁力Fが鉄板15で吸収されるので、第二の磁性体反転表示パネル1bの表示用磁性体7は動かされず、磁性体反転表示パネル1bの磁性体7は透明な表面板2側に緑色(S極側表面部分)を向けた整列をし続けることができる。
【0015】
特に、本実施の形態では、隔壁4をハニカム構造としてあり(図2参照)、表面板2と隔壁4と裏面板3とを接着剤(図示せず)により固着すると共に、第一の磁性体反転表示パネル1aと鉄板15と第二の磁性体反転表示パネルとを接着剤14で全面的に固着して一体としてあるので、パネル強度の高いものとなっている。
【0016】
図2は、本実施の形態の応用例を示す姿図であり、3枚の両面式磁性体反転表示パネル1を綴じ具16に綴ったもので、綴じ具16に固設したリング17を両面式磁性体反転表示パネル1の四方を取囲むフレーム18の丸孔18aに通して綴じ込んだものである。尚、綴じ具16の中央部には内側への折り目16aを形成しており、綴じ具16を折り目16aで折り畳んで携行を容易としてある。本実施の形態の応用例では図に示す通り、合計6面の表面板1a,1bとなるので、さらに多くの筆記を行うことができる。
【0017】
以上、本実施の形態を詳述したが、本発明は、前記実施の形態に限定されるものではなく、特許請求の範囲に記載した本発明の要旨の範囲内で種々の変更を行うことができる。尚、本発明の両面式磁性体反転表示パネルは、透明な表面板及び裏面板間の隔壁の壁面間に分散液体(表示用磁性体が降伏値を有する液体中に分散された液体)を収容する代わりに、分散液体を収容したマイクロカプセルを透明な表面板と裏面板間に配設したパネル構造のものでもかまわない。
【0018】
【発明の効果】
本発明の両面式磁性体反転表示パネルは以上のような構造なので、一方の磁性体反転表示パネルの表面板側から筆記を行う際に、他方の磁性体反転表示パネルに影響を与えることがないものとなった。

BACKGROUND OF THE INVENTION
The present invention relates to a double-sided magnetic reversal display panel.
[0002]
[Prior art]
Magnetic reversal display panels are conventionally known, and are also described, for example, in Japanese Patent Publication No. 59-32796. By the way, a conventional magnetic reversal display panel will be briefly described with reference to the drawings. As shown in FIG. 3, the magnetic reversal display panel 100 a has a partition wall 4 disposed between a transparent front plate 2 and a back plate 3. A plurality of liquid storage chambers 5 are formed between them. Further, the dispersion liquid 6 accommodated in the liquid storage chamber 5 is a liquid having a yield value in which the display magnetic body 7 is dispersed in the liquid 8 composed of the dispersion medium and the thickener, and the display magnetic body 7 is green. The S-pole side surface portion colored in a white and the N-pole side surface portion colored in white.
[0003]
In order to write the display information on the magnetic body reversal display panel 100a, as shown in FIG. 3, for example, the transparent surface plate 2 is white (the surface portion on the N pole side) and the pen-shaped magnetic pen 9 is used. When the magnetic pole portion 10 having an N pole as a magnetic reversal magnetic pole is moved in the direction of the arrow T while being in contact with the transparent surface plate 2, the green color of the display magnetic body 7 is increased by the magnetic force F. (S pole side surface portion) is arranged on the surface plate 2 side which is linearly transparent. In this case, a green (S pole side surface portion) display line is displayed on the white (N pole side surface portion) surface plate 2 side.
[0004]
The magnetic eraser 11 is used when the surface plate 2 on which green (S pole side surface portion) is displayed on the white background is returned to white. The magnetic eraser 11 is a flat magnet and has a magnetic reversal magnetic pole of an S pole 12 and an N pole 13. When the S pole 12 side of the magnetic eraser 11 is brought into contact with the green (S pole side surface portion) display of the surface plate 2 of the magnetic body reversal display panel 100a, the white color of the display magnetic body 7 (N pole side surface portion). Is arranged on the transparent surface plate 2 side and becomes white.
[0005]
Recently, in order to increase the amount of written information, it is desired to be able to write on both sides of the panel. FIG. 4 shows a double-sided structure in which two magnetic body reversal display panels 100a and 100b are fixed with an adhesive 14 so that their back surfaces face each other so that writing can be performed on both sides.
[0006]
[Problems to be solved by the invention]
However, as described above, since the magnetic reversal display panel 100a is a non-magnetic body except for the display magnetic body 7, for example, the magnetic pole portion 10 of the magnetic pen 9 is placed on the surface of the magnetic reversal display panel 100a. When moved in the direction of arrow T while in contact with the face plate 2, the magnetic pen 9 is aligned with white (N pole side surface portion) facing the surface plate 2 side of the magnetic material reversal display panel 100 a by the magnetic force F of the magnetic pen 9. The display magnetic body 7 is reversed to draw a green (S pole side surface portion) writing line, and at the same time, green (S pole side surface portion) is placed on the transparent surface plate 2 side of the magnetic body reversal display panel 100b. There is a problem that the magnetic material for display 7 that has been aligned is reversed and an unnecessary white (N pole side surface portion) writing line is drawn on the surface plate 2 of the magnetic material reversal display panel 100b. It was.
[0007]
In view of the above circumstances, the present invention proposes a double-sided magnetic reversal display panel that does not affect the other magnetic reversal display panel when writing from the surface plate side of one magnetic reversal display panel. The purpose is to do.
[0008]
[Means for Solving the Problems]
Next, the present invention devised to solve the above problems will be described.
“1. A magnetic body for display which has an S pole and an N pole, and the S pole side surface portion and the N pole side surface portion are colored in different colors, and the display magnetic body is mainly composed of a dispersion medium and a thickener. A first magnetic body inversion display panel and a second magnetic body inversion display in which a transparent surface plate is arranged on the surface side of a plurality of liquid storage chambers containing a dispersion liquid dispersed in a liquid having a yield value as a component. The panel is arranged so that the back side faces each other on both sides of a single iron plate.
2. In the first magnetic body reversal display panel and the second magnetic body reversal display panel, a partition wall having a honeycomb structure is fixed between a transparent front plate and a back plate, and the liquid storage chamber is provided between the partition wall surfaces. It is characterized by that.
3. In the first magnetic body reversal display panel and the second magnetic body reversal display panel, a partition wall having a honeycomb structure is fixed between a transparent front plate and a back plate, and the liquid storage chamber is provided between the partition wall surfaces. In addition, the first magnetic body reversal display panel and the second magnetic body reversal display panel are integrally bonded to both surfaces of the one iron plate so that the back plates face each other. To do. "
[0009]
In the present invention, the first magnetic body reversal display panel and the second magnetic body reversal display panel are arranged so that the back surfaces thereof face each other on both surfaces of one iron plate. When writing by moving the display magnetic body from the surface plate side of the panel with the magnetic force of the magnetic pen, the iron plate between the first magnetic body inversion display panel and the second magnetic body inversion display panel absorbs the magnetic force. This is because the display magnetic body of the second magnetic body inversion display panel is not moved and does not affect the second magnetic body inversion display panel.
[0010]
Also, in the magnetic reversal display panel on the writing side, in the present invention, since there is an iron plate on the back side of the panel, the magnetic field lines generated from the magnetic poles are attracted to the iron plate near the magnetic poles, and are easily perpendicular to the panel surface. As described above, there is a synergistic effect that the contour of the writing line by the magnetic pen is adjusted and the erase by the magnetic eraser can be performed cleanly. In addition, since one iron plate is shared by two magnetic reversal display panels, the cost is excellent and the weight can be reduced. For example, a plurality of double-sided magnetic reversal display panels are stacked and bound, In such a form, it is possible to write more and facilitate carrying.
[0011]
Further, the first magnetic body reversal display panel and the second magnetic body reversal display panel are fixed with a honeycomb structured partition wall between the transparent front plate and the back plate to form a liquid storage chamber between the partition wall surfaces. The purpose is to increase the rigidity of the panel by fixing the front plate, the back plate, and the partition walls of the honeycomb structure so as not to move, and further, the first magnetic body inversion display panel and the second magnetic body inversion The display panel is fixed to the both sides of a single iron plate so that the back plates face each other so that they are integrated with each other by combining the first magnetic body inversion display panel and the second magnetic body inversion display panel. By using an iron plate as an integrated structure, the strength of the double-sided magnetic reversal display panel is synergistically improved, and strength can be obtained without applying a reinforcing plate such as plywood or particle board. It is.
[0012]
Further, as a method of fixing the honeycomb structured partition wall to the transparent front plate and the back plate, it is possible to use an adhesive or a means by heat welding, and the fixing force is dispersed in the liquid storage chamber. There is no particular limitation as long as the means is not affected by the liquid. In addition, as a method for fixing the back plate and the iron plate, a means for adhering them with an adhesive or a double-sided adhesive tape can be used. The adhesive and the double-sided pressure-sensitive adhesive tape have a higher fixing strength if the back plate and the iron plate are fully spread, but if the back plate and the iron plate are not easily peeled from each other, they are partially Even if it is spread out, if at least the four corners of the plate are fixed, both may be integrated.
[0013]
