    摘要： An electronic endoscope apparatus provided with an electronic endoscope having arranged thereon a solid-state image pickup element at an insertion portion, and external devices such as a light source device for supplying an illumination light to the electronic endoscope, a video processor for processing an electrical signal transmitted from the solid-state image pickup element of the electronic endoscope to produce a video signal. An electrical connection portion for electrically connecting the electronic endoscope and the video processor is provided at a connector portion which is provided at an end of a universal cord which connects the electronic endoscope and the light source device. An electromagnetic interference countermeasure member is provided which covers at least one of the connector portion, the universal cord and the external devices. A dual shield around a signal line is also provided which includes spirally-wound lead wires having different diameters and ends connected to video ground.

    摘要： An endoscope system includes an endoscope and a disposable protection cover for covering the endoscope and provided with at least one channel tube. The endoscope has an insertion section which is insertable into a cavity to be inspected, and an operation section connected to a proximal end of the insertion section. The channel tube is arranged relative to the protection cover with a first layout at the operation section and at the proximal end of the protection cover, and with a second layout at the distal end of the protection cover to provide a natural operation feel. A package cover assembly includes package covers for covering the protection cover and the operation section of the endoscope, respectively, and these package covers are detachably attached to a mouthpiece at the proximal end of the insertion section. An over-cover member for covering the protection cover has a region to be engaged by an external holder member which is to support the over-cover member during insertion or removal of the protection cover with respect to the over-cover member. These cover members serve to prevent the protection cover from contamination.

    摘要： An endoscope system consists mainly of: an endoscope having a solid-state imaging device and an objective optical system that converges an object image on said solid-state imaging device; and a signal processing unit that processes an image signal produced by the endoscope so as to produce a video signal. The objective optical system includes an optical phase modulation member. The optical phase modulation member exhibits a response of 0.2 or more derived from an optical transfer function relative to a spatial frequency on the solid-state imaging device determined based on the Nyquist theorem, that is, a Nyquist frequency, over a wider range of distances than a depth of field offered by an objective optical system not having the optical phase modulation member.
