    摘要： An endoscope capable of being autoclaved in accordance with the present invention includes an insertion unit, an internal endoscope space, and contents. The insertion unit has a soft member, which is made of a soft polymeric material, as at least part of a casing thereof. The internal endoscope space includes the internal space of the insertion unit that is formed at a first sealing level at which the internal space is sealed in a watertight manner relative to an outside. The contents include at least one hermetically sealed unit (40) composed of a plurality of airtight partition members (37, 41, 47) and formed at a second sealing level higher than the first sealing level by joining the meeting portions of the airtight partition members (37, 41, 47) using an airtight joining material. All or part of the airtight partition members is stowed in the internal endoscope space. Even when high-pressure high-temperature steam permeates through the soft member of the insertion unit which is made of a polymeric material, and invades into the internal endoscope space formed at the first sealing level, the high-pressure high-temperature steam will be hindered from invading into the hermetically sealed unit (40) included in the contents and formed at the second sealing level.

    摘要： Endoscope focus state detectors, and automatic lens setting devices and exposure triggering devices provided therewith, for use where a hard or soft endoscope (4) is inserted into a body cavity and illuminating light fed from a light source (60) for observation or diagnosis via an eyepiece 3 and a focus state detection light source (33,67) projects light via an aperture (15) to be transmitted via the endoscope optical system and detect reflected light in order to determine the focus state, with reference to a plane in which an image is to be recorded. The light receiving means (11) for detecting the state of focus includes means for increasing the signal-to-noise ratio by reducing or eliminating any reflected illuminating light that would otherwise be incident upon the light receiving means (11).

    摘要： A photosensor (21) suitable for use in optical systems where a light projected onto an object (2) as a spot via an image forming lens (1) by a light-emitting means (12) is reflected to a light-receiving, photo-electric transducer provided with a through-hole, and means (23) preventing light from the light source (12) from leaking radially directly to the photo-electric transducer surface so that the dark current component is maintained low, and the state of focusing may be detected with high precision.
    It has been found difficult to detect the state of focus with high precision using a simple structure in an optical system where an optical image of an object (2) to be viewed or photographed is clearly formed on a predetermined image forming surface, such as a film surface, by a photographic or image-forming objective lens (1), and the proposed photosensor (21) permits light projected as a spot onto an object (2) to be received by a light-receiving element provided with a through-hole (22) in a photo-electric transducer surface. A means (23) preventing light from the light emitting means (12) from leaking radially directly to the photo-electric transducer surface so that the state of focus may be detected with high precision using a simple structure.
