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.
摘要翻译：第一光学适配器可拆卸地安装在具有观察光学系统和照明光学系统的内窥镜的远端上，其中已经设置在内窥镜的观察光学系统内的给定位置的孔径光阑过去，被放置在光学适配器的观察光学系统内，使得其光轴与用于内窥镜的观察光学系统的光轴相一致。光学适配器从具有不同F数的一组适配器中选择，或者光学适配器设置有可互换的一组不同的F数隔膜。通过仅根据观察光学系统的亮度，观察到的物体的景深和亮度，仅选择适当的前光学适配器或隔膜来改变内窥镜装置的观察光学系统的F数，以及作为观察光学系统的观察范围和视角等，以获得具有最佳亮度的清晰的观察图像。

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.
