摘要： An electronic endoscope apparatus has an arrangement that its discrimination circuit discriminates the type or the operational state of the light source in accordance with a discrimination signal transmitted from a discrimination signal generator, and in accordance with the result of the discrimination, the processing operation to be performed by its video signal processing circuit is changed over to correspond to the difference in the type or the operational state of the light source. The video signal processing circuit performs a proper signal processing operation to correspond to the difference in the type of the light source to prevent deterioration in the image quality. The electronic endoscope apparatus is structured so that a different type light source can be adaptably connected to it.

摘要： A seal lip of an oil seal is in slidable contact with a peripheral surface of a shaft. A lubricating oil supply section for collecting adhered oil and dropping it on the shaft is provided at a forward end portion of an installation section. The lubricating oil supply section has projections formed on the inner peripheral surface of the installation section to collect oil on the surface thereof. The surface of each projection has a recess for temporarily accumulating oil. Guidance projections, or a slope for collecting the oil, and dams are formed on a forward end face of the installation section to block the oil flowing down along the circumferential direction on the forward end face and guides the oil toward each projection.
