摘要：
PROBLEM TO BE SOLVED: To provide an electric field detection output device that simply and accurately measures and outputs an electric field intensity or direction, achieves miniaturization of an entire device for users to easily grip, and is superior in simplicity, quick report property, accuracy and non-invasiveness.SOLUTION: An electric field detection output device 1, which is for displaying an electric field intensity or direction by being inserted within an electric field, comprises: an upper electrode 2a and a lower electrode 2b that serve as almost square flat plate electrodes a virtual grounding type current detector 3 that detects an AC current generated by an electric charge induced by the upper electrode 2a and lower electrode 2b two LEDs 7 in which the number of the LEDs emitting light varies in accordance with intensity of a detection object and a battery 4 for driving the virtual grounding type current detector 3 and the LED 7. When electric charge is induced in the upper electrode 2a and lower electrode 2b, the number of the LEDs 7 emitting the light varies in accordance with a numeric value of the detection object or intensity and direction to thereby allow a user to easily grasp the electric field intensity.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】電界強度や方向を、簡便に精度よく計測して出力し、利用者がそれを容易に把握可能とするために、装置全体の小型化を実現し、簡便性、速報性、精度、非侵襲性に優れた電界検知出力装置を提供する。【解決手段】電界内に挿入されることにより電界強度や方向を表示するための電界検知出力装置1は、略正方形の平板電極である上部電極2a及び下部電極2bと、この上部電極2a及び下部電極2bに誘起された電荷により生じる交流電流を検出する仮想接地型電流検出器3と、検知対象の強度に応じて発光する個数が変化する2つのLED7と、仮想接地型電流検出器3及びLED7を駆動させるための電池4とを備えている。上部電極2a及び下部電極2bに電荷が誘起されると、検知対象の数値または強度、及び方向に応じて2つのLED7の発光する個数が変化するので、利用者は電界強度を容易に把握することが可能になる。【選択図】図1
