Description
本発明は、電気回路を学習するのに用いる電気回路板であって、簡単な構造で通電状態が識別できる通電変色性電気回路板に関するものである。 The present invention relates to an electric circuit board used for learning an electric circuit, and relates to an electric current-changing electric circuit board that can identify an electric current state with a simple structure.
従来、家庭等で個人的に電気回路の学習するのに、板等の上に電線を配し、電線の間に豆電球を接続して通電の確認を行なう実験、ゲーム用回路が昔より公知である。一方、特開平３−１３３７９号公報（特許文献１参照）には、熱変色性材料を用いるパネル、バッテリーチェッカー等の表示素子が開示されている。
しかし、上記従来の電線及び豆電球よりなる実験、ゲーム用回路では、基板の大きさ及び立体的高さとも大き過ぎて、実験、ゲーム用として取り扱いが不便であり、また製作費用も高くなるため、個人一人一人が持つには不適当であった。また、特開平３−１３３７９号公報（特許文献１参照）に開示されている表示素子は、インジケーターとして用いるものであり、実験、ゲーム用回路とする思想は開示されていない。 However, in the experiment and game circuit composed of the above-described conventional electric wires and miniature light bulbs, the size of the board and the three-dimensional height are too large, which is inconvenient to handle for experiments and games, and the production cost is high. It was inappropriate for each individual to have. In addition, the display element disclosed in Japanese Patent Laid-Open No. 3-13379 (see Patent Document 1) is used as an indicator, and does not disclose the idea of an experiment and a game circuit.
本発明の目的は、上記問題を解決し、実験、ゲーム用として使用に便利であり、また製作費用が高くつかず、個人一人一人に持つことができる実験、ゲーム等用に適した電気回路板を提供することである。 An object of the present invention is to solve the above-mentioned problems, and is convenient for use in experiments and games, and is inexpensive to produce, and can be held by each individual, suitable for use in experiments, games, etc. Is to provide.
本発明者は鋭意検討した結果、実験、ゲーム等に用いる電気回路であって、当該電気回路が板状の基材上に通電することにより、発熱する導電層を有し、端子部分以外を当該導電層上に感熱変色性材料層を有する通電変色性電気回路板とすることで、構造が簡単で取り扱いが容易であり、また製作費用が高くなく実験、ゲーム用に適したものとなることを見出した。また、前記導電層と感熱変色性材料層の間に不変色性色材層を有する通電変色性電気回路板又は前記導電層の上に感熱変色性材料と不変色性色材を一体とする層を有する通電変色性電気回路板とすることで、通電による変色の色を任意に設定できるため、通電の識別性が向上した。一方、前記電気回路板の端子に通電するための電源ユニットであって、電池を収納する容器に前記端子に当接する金属棒よりなる通電変色性電気回路板用電源ユニットとすることにより、上記通電変色性電気回路板の実験、ゲームとして用いる場合、使用に便利である。さらに前記電池と金属棒の間に熱変色部分を設けると、通電変色性電気回路板用電源ユニットに通電の表示を目で認識できるので、実験、ゲーム用に適している。他方、前記通電変色性電気回路板と前記通電変色性電気回路板用電源ユニットからなる通電変色性電気回路セットとすれば、回路と電源ユニットを別々に揃える必要がなく使用に便利である。 As a result of intensive studies, the inventor is an electric circuit used for experiments, games, etc., and the electric circuit has a conductive layer that generates heat when energized on a plate-like base material, except for the terminal portion. By using a current-changing color-changing electric circuit board having a heat-sensitive color-changing material layer on the conductive layer, the structure is simple and easy to handle, and the production cost is low, making it suitable for experiments and games. I found it. Further, a current-changing color-changing electric circuit board having a non-changing color-changing color material layer between the conductive layer and the thermo-sensitive color-changing material layer, or a layer in which the thermo-sensitive color-changing material and the non-color-changing color material are integrated on the conductive layer. By using a current-carrying color-changing electric circuit board having a color, the color of the color change due to the current-carrying can be arbitrarily set. On the other hand, a power supply unit for energizing the terminals of the electric circuit board, wherein the energization color changing electric circuit board power supply unit is made of a metal rod abutting against the terminals in a container for storing a battery. It is convenient for use when used as an experiment or game for a color-changing electric circuit board. Further, when a thermochromic portion is provided between the battery and the metal rod, the power-on display can be visually recognized on the power-supply unit for the color-changing electric circuit board, which is suitable for experiments and games. On the other hand, if an energization color-changing electric circuit set including the energization color-changing electric circuit board and the power-supply color-changing electric circuit board power supply unit is used, it is not necessary to arrange the circuit and the power supply unit separately, which is convenient for use.
本発明は、上記構成としたことで、構造が簡単で取り扱いが容易であり、また製作費用が高くなく実験、ゲーム用に適しており、また回路の通電状態を変色の色でたどることができるので、通電していることが、一目瞭然に判ることでも実験、ゲーム等用に最適である。 Since the present invention is configured as described above, the structure is simple and easy to handle, the production cost is low, and it is suitable for experiments and games, and the current-carrying state of the circuit can be traced in a discolored color. Therefore, it is optimal for experiments, games, etc. even if it is obvious that the power is on.
