    摘要: This rigid electronic endoscope has an endoscope having an elongate insertable part connected to the front part of an operating part which is also a holding part on the base side and formed of a solid state imaging device which can output an electric signal by electrically converting an object image in this insertable part and a conductive shielding member sheathing this insertable part. The electric signal obtained by this endoscope is input into a signal processing circuit. The ground terminal of this signal processing circuit is electrically connected to the above mentioned shielding member and is isolated from a ground terminal on the external current source side.

    摘要: In an endoscope having an objective optical system and an illuminating optical system formed in the tip of the insertable part; an incised or inclined surface is formed on the periphery of the tip by incising or cutting away the outer surface of the tip to provide a surface which is not parallel with the longitudinal axis of the insertable part but is closely adjacent to the objective optical system.
