Abstract

PURPOSE:To eliminate the influence from the noises of a transmitting circuit by balancing the inpedance at the detecting element side from the positive and negative input terminals of a pre-amplifer with the use of a balance resistor and a coupling capacitor. CONSTITUTION:The detected output of a photoelectric conversion detecting element 1, which is balanced by a negative resistor 7 grounded to the earth through balance resistors 9a and 9b, is impressed through a double core sheld wire 8 upon the positive and negative terminals of a pre-amplifier 4, respectively, so that the differential output corresponding to the detected value is generated from the amplifier 4. The wire 8 and the amplifier 4 are connected by means of coupling capacitors 10a and 10b and grounded DC balance resistors 11a and 11b so that the impedance, if the element 1 is seen from the side of the amplifier 4, is completely balanced in DC and AC manners. As a result, the detected value, which is generated by the amplifier 4 in a differential amplification, is cleared from the outside noises so that the transmission of satisfactory signals having a wide range can be accomplished.
