Electronic endoscope apparatus having an isolation circuit for isolating a patient circuit from a secondary circuit
First Claim
1. An electronic endoscope apparatus having an isolation circuit comprising:
- an endoscope provided with an imaging means converting the photoinformation of an object into an output electric signal;
a video signal processing means processing the output electric signal of said imaging means into a video signal;
an isolating means for separating and for isolating said video signal processing means into a) a patient circuit including said imaging means and b) a secondary circuit which is a circuit not included in said patent circuit; and
a signal producing means for making either one of said patient circuit and said secondary circuit a transmitted side circuit and the other a transmitting side circuit and for producing a signal required by said transmitted side circuit based upon a signal forming an image transmitted to the transmitted side circuit through said isolating means from the transmitting side circuit.

Abstract
The electronic endoscope apparatus having an isolation circuit of the present invention is provided with an endoscope provided with an imaging device converting the photoinformation of an object to an electric signal and a video signal processing device processing the output signal of the imaging device to be a video signal. An isolation circuit separates and isolates the circuit forming the video signal processing device into a patient circuit including the imaging device and a secondary circuit which is a circuit not included in the patient circuit. A signal producing circuit makes either one of the patient circuit and secondary circuit a transmitted side circuit and produces a signal required by the transmitted side circuit on the basis of a signal forming a video transmitted to the transmitted side circuit through the isolation circuit from the transmitting side circuit.
