EQUILIBRIUM BALANCING FUNCTION INSPECTING DEVICE

摘要

PURPOSE:To easily diagnose a disease by standardizing a symptom and to realize easy handling by comprising a pair of plane photoelectric sensors arranged at an angle symmetrically to a center line, and a bridge circuit consisting of each plane photoelectric sensor and a resistor. CONSTITUTION:The output of an output voltage detection circuit 21 in the bridge circuit 3 assembled with the photoelectric sensors 1, 2 and the resistors R1, R2 is adjusted so as to be set at (0V). Then, a rotational angle detecting part 5 generates a (+) output voltage, for example, when the sensor is rotated rightward, and a (-) output voltage when it is rotated leftward, respectively corresponding to a rotational angle. Meanwhile, the output voltage when the face of a patient is rotated horizontally in right and left directions in a state where one front point is observed by the eyes of the patient can be obtained at an eye-ball motion detecting part 23. A voltage detected at the output voltage detection circuit 21 and that detected at the eye-ball motion detecting part 23 are added at an adder circuit 25 after being amplified at amplifier circuits 22 and 24, respectively. After that, an addition result obtained at the adder circuit 25 is displayed on a display device 26 with the output voltages of the rotational angle detecting part 5 and the eye-ball motion detecting part 23.
