以下、本発明の実施の形態を適用した熱変色性インキの消去装置の一例を、図1に基づいて説明する。Hereinafter, an example of a thermochromic ink erasing apparatus to which an embodiment of the present invention is applied will be described with reference to FIG.

図1に示すように、本体ハウジング収納部1と本体ハウジング板状部2がヒンジ部3によって可動する構造であり、ヒンジ部の対辺側には前記本体ハウジング収納部1と前記本体ハウジング板状部2が弾性力を提供するためのコイルスプリング4で結合されており、前記コイルスプリング4の中心には案内軸5が前記本体ハウジング板状部2の設置孔6に貫通して固定され、本体ハウジング収納部1には案内軸5が進行するための案内孔7を有している。As shown in FIG. 1, a main body housing storage portion 1 and a main body housing plate-like portion 2 are movable by a hinge portion 3, and the main body housing storage portion 1 and the main body housing plate-like portion are arranged on opposite sides of the hinge portion. 2 are coupled by a coil spring 4 for providing an elastic force, and a guide shaft 5 is fixed to the center of the coil spring 4 through the installation hole 6 of the main body housing plate-like portion 2. The storage portion 1 has a guide hole 7 for the guide shaft 5 to travel.

前記、本体ハウジング収納部1の上部には凸レンズ8が設置され、本体ハウジング板状部2には円形孔9が開けられており、前記コイルスプリング4に加えられる荷重が本体ハウジング収納部1だけの場合は、本体ハウジング収納部1と前記本体ハウジング板状部2に空間を設けられている状態になり、前記本体ハウジング収納部1の上部を本体ハウジング板状部2側に押すことで、前記本体ハウジング収納部1と前記本体ハウジング板状部2を結合しているコイルスプリング4が圧縮されることにより、前記本体ハウジング収納部1と前記本体ハウジング板状部2は重合された状態になり、前記凸レンズ8と前記本体ハウジング板状部2の円形孔9の中心は同一軸線上に設置されている。A convex lens 8 is installed on the upper part of the main housing housing part 1, and a circular hole 9 is formed in the main body housing plate-like part 2, so that the load applied to the coil spring 4 is applied only to the main housing housing part 1. In this case, a space is provided in the main body housing storage portion 1 and the main body housing plate-like portion 2, and the upper portion of the main body housing storage portion 1 is pushed toward the main body housing plate-like portion 2 side, thereby By compressing the coil spring 4 that couples the housing housing part 1 and the main body housing plate-like part 2, the main body housing housing part 1 and the main body housing plate-like part 2 become superposed, The centers of the convex lens 8 and the circular hole 9 of the main body housing plate-like portion 2 are installed on the same axis.

本体ハウジング収納部1には、電池10と単極単投スイッチ11と電球12と単極双投スイッチ13とキャパシター14と、本体ハウジング収納部1と本体ハウジング板状部2が重合した際に本体ハウジング板状部2に対して、傾斜角を有したU字型のニクロム線15と前記ニクロム線15を保持するための基板16を収納している。When the battery 10, the single-pole single-throw switch 11, the light bulb 12, the single-pole double-throw switch 13, the capacitor 14, the main body housing storage 1 and the main body housing plate-like portion 2 are overlapped, The housing plate-like portion 2 accommodates a U-shaped nichrome wire 15 having an inclination angle and a substrate 16 for holding the nichrome wire 15.

前記傾斜角を有したU字型のニクロム線15は、本体ハウジング収納部1と本体ハウジング板状部2が重合した際に、本体ハウジング板状部2の円形孔9からU字型のニクロム線15のアーチ部17突出するように前記ニクロム線15を保持するための基板16が設置されている。The U-shaped nichrome wire 15 having the inclination angle is formed by the U-shaped nichrome wire from the circular hole 9 of the main body housing plate-like portion 2 when the main body housing accommodating portion 1 and the main body housing plate-like portion 2 are superposed. 15 substrate 16 for the arch portion 17 holds the nichrome wire 15 so as to protrude is disposed of.

図2の回路図において、図1の本体ハウジング収納部1に収納された構成部品の接続を説明すると、電池10の正極から抵抗体であるフィラメントを使用した電球12を介し、本体ハウジング収納部1と本体ハウジング板状部2が重合した際に導通するように設けられた単極単投スイッチ11の可動片Aに接続され、前記単極単投スイッチ11の接点Bから単極双投スイッチ13の接点Cに接続され、単極双投スイッチ13の可動片Dはキャパシター14の正極に接続され、ニクロム線15は単極双投スイッチ13の接点Eとキャパシター14の負極と電池10の負極に接続される。In the circuit diagram of FIG. 2, the connection of the components housed in the main housing housing part 1 of FIG. 1 will be described. The main body housing housing part 1 is connected to the positive electrode of the battery 10 through a light bulb 12 using a filament as a resistor. Are connected to a movable piece A of a single-pole single-throw switch 11 provided so as to be conductive when the plate-like portion 2 of the main body housing is superposed, and a single-pole double-throw switch 13 from a contact B of the single-pole single-throw switch 11 The movable piece D of the single pole double throw switch 13 is connected to the positive electrode of the capacitor 14, and the nichrome wire 15 is connected to the contact E of the single pole double throw switch 13, the negative electrode of the capacitor 14, and the negative electrode of the battery 10. Connected.

消去作業をしていない状態の側面図は図4に示すように、本体ハウジング収納部1と本体ハウジング板状部2はコイルスプリング4によって空間を保持されており、本体ハウジング収納部1に設置された単極単投スイッチ11は非導通状態になっているため、電池10から電球12を介してキャパシター14には充電されていない。As shown in FIG. 4, the side view of the main body housing housing 1 and the main body housing plate-like portion 2 is held in a space by a coil spring 4 and installed in the main body housing housing 1. Further, since the single-pole single-throw switch 11 is in a non-conductive state, the capacitor 14 is not charged from the battery 10 via the light bulb 12.

消去作業を行っている状態の本体ハウジング収納部1と本体ハウジング板状部2の側面図は、図5に示すように本体ハウジング収納部1と本体ハウジング板状部2が重合し、図2の単極単投スイッチ11は導通状態であり、電池10から電球12を介してキャパシター14に電荷を充電され、充電中は電球12に電流が流れるため電球12が点灯し、キャパシター14に充電していることが視認できるが、視認することが必要なければ図3のように抵抗器Rでも構わない。The side view of the main housing housing part 1 and the main body housing plate-like part 2 in the state where the erasing operation is performed is shown in FIG. The single-pole single-throw switch 11 is in a conductive state, and the capacitor 14 is charged from the battery 10 via the light bulb 12. During the charging, a current flows through the light bulb 12, so that the light bulb 12 is lit and the capacitor 14 is charged. However, if it is not necessary to visually recognize, the resistor R may be used as shown in FIG.

前記キャパシター14への充電が完了して、電球12が消灯した後に本体ハウジング収納部1の側面に設置されている単極双投スイッチ13を、図2の回路図で示す単極単投スイッチ11側に接続されている接点Cから、ニクロム線15側に接続されている接点Eに切り替えることにより、キャパシター14に充電されていた電荷はニクロム線15を発熱させ、図5の本体ハウジング板状部2を紙面18に当て、熱変色性インキで書かれた筆記線上に接触したニクロム線15が発熱することにより、筆記線を消去することができ、本体ハウジング収納部1の上部に設置されている凸レンズ8により消去部分を拡大して視認することができる。A single-pole single-throw switch 11 shown in the circuit diagram of FIG. 2 is replaced with a single-pole double-throw switch 13 installed on the side surface of the main housing housing 1 after the charging of the capacitor 14 is completed and the light bulb 12 is turned off. By switching from the contact C connected to the side to the contact E connected to the nichrome wire 15 side, the charge charged in the capacitor 14 causes the nichrome wire 15 to generate heat, and the main body housing plate-like portion of FIG. 2 is applied to the paper surface 18 and the nichrome wire 15 in contact with the writing line written with the thermochromic ink generates heat, so that the writing line can be erased and is installed in the upper part of the main body housing housing 1. The erased portion can be enlarged and visually recognized by the convex lens 8.

電池10の供給電力が低下した場合では、図5に示すように本体ハウジング収納部1と本体ハウジング板状部2が重合し、図2の単極単投スイッチ11を導通状態にして、キャパシター14に電荷を充電する時間を長くする作業を行い、後に本体ハウジング収納部1の側面に設置されている単極双投スイッチ13を、図2の回路図で示す単極単投スイッチ11側に接続されている接点Cから、ニクロム線15側に接続されている接点Eに切り替えることにより、消去可能な電力をキャパシター14から通電発熱体であるニクロム線15に供給できる。When the power supplied to the battery 10 decreases, as shown in FIG. 5, the main housing housing part 1 and the main body housing plate-like part 2 are superposed, and the single-pole single-throw switch 11 shown in FIG. 2 is connected to the single-pole / single-throw switch 11 shown in the circuit diagram of FIG. The erasable power can be supplied from the capacitor 14 to the nichrome wire 15, which is an energized heating element, by switching from the contact C to the contact E connected to the nichrome wire 15 side.
