    摘要： A first optical adapter is to be detachably mounted on the distal end of an endoscope having an observation optical system and an illumination optical system, in which an aperture diaphragm which has been disposed at a given position within the observation optical system of the endoscope in the past, is disposed instead within an observaiton optical system of the optical adapter such that its optical axis is in agreement with that of the observation optical system for the endoscope. The optical adapter is selected from a set of adapters having different F numbers or the optical adapter is provided with a set of different F number diaphragms which are interchangeable. This enables the F number of the observation optical system of the endoscope apparatus to be changed by merely selecting the appropriate front optical adapter or diaphragm, depending upon brightness of the observation optical system, depth of field and brightness of an object being observed, as well as observation range and view angle of the observation optical system and the like, in order to obtain a clear observation image with optimum brightness.

    摘要： An endoscope apparatus includes an insertion section adapted to be inserted into a desired region. A distal end structure is fixed to the distal end of the insertion section. The structure has a support portion on which a solid-state image sensor is mounted to be movable in a direction parallel to a light receiving surface of the sensor. The sensor is pressed against the support portion by a leaf spring, thereby being prevented from moving in a direction perpendicular to the light receiving surface. A connector is fixed to the proximal end of the insertion section and detachably connected to a control unit.
