摘要:
A single lens reflex camera includes a vertical open topped U-shaped bracket mounted in the camera body below the pentaprism, a forwardly located lens mount separably coupled to an objective lens and pairs of links mutually pivoted between their ends connected between the bracket arms and corresponding edges of the lens mount to support the latter in a fixed orientation for linear longitudinal movement along the camera optical axis. A light tight collapsible conduit extends between the camera body and lens mounts and includes telescoping members with relatively slidable side and bottom walls and an accordian top wall. A rack carrying slide arm projects rearwardly from the lens mount and is engaged by a motor driven gear to longitudinally shift the lens mount. The motor is controlled manually or in response to a focus detecting device and the lens mount may be motor advanced and retracted or motor advanced and spring retracted. The lens diaphragm is automatically stopped down by a camera housed mechanism and diaphragm control information is transmitted from the lens mount to the camera body.

An electrical shutter type TTL single-lens reflex camera, with a movable mirror diagonally located within the photographic optical path to project object light to a viewfinder system during object observation and retractable from the optical path during photographic exposure, incorporates a light measurement device with a first light measuring element arranged for average light measurement of the light reflected from the movable mirror during object observation, at least part of the movable mirror being made transparent, or of a half mirror, to divide the object light into reflected light and light projected through the plane of the mirror. A second light measuring element is located to carry out spot metering on an object from the light projected through the plane of the movable mirror during object observation. A third light measuring element is located to receive reflected object light from a shutter curtain surface and/or the film surface for selection of average light measurement and spot metering on the object during photographic exposure. A manually operable selector selectively connects either the first or second light measuring element to an exposure information indicating device. The third light measuring element is adapted to be changed from average light measurement or to spot metering and to provide respective outputs representative thereof, such that exposure control with average light measurement or spot metering is obtainable from an exposure control circuit responsive to either output of the third light measuring element. In response to the selection of the first light measuring element by the manually operable selector, the third light measuring element is changed over for average light measurement, and in response to the selection of the second light measuring element, the third light measuring element is changed over for spot metering.

An exposure indicating device for single lens reflex cameras which are selectively settable to automatic aperture control or automatic shutter speed control modes includes an exchangeable lens which has first and second information transmitting members, and a diaphragm setting member settable to one of a number of manually set aperture positions and to an automatic aperture control position. The first transmitting member transmits to a first information receiving member, first information of the step-difference from a minimum to a preset f-number of the lens independently of the set position of the diaphragm setting member. The second transmitting member transmits to a second information receiving member, second information of a maximum f-number only when the diaphragm setting member is set to the automatic aperture control position. The second transmitting member also serves as a mode selection and scale selection member which switches the camera into the automatic aperture control mode and enables observation of an aperture scale within a finder view field when the diaphragm setting member is set to the automatic aperture control position. The second transmitting member also switches the camera into the automatic shutter speed control mode and enables observation of a shutter speed scale within the finder view field when the diaphragm setting member is set to any one of the manually set aperture positions. The first information thus received enables automatic shutter speed control, and indication of an automatically controlled shutter speed prior to a stopping-down operation. The first and second information thus received are composed with each other, only in the automatic aperture control mode, to generate information of the minimum f-number of the lens, which enables indication of an f-number corresponding to an automatically controlled aperture prior to the stopping-down operation.

A lens-exchangeable, single lens reflex camera of the TTL light measurement type, which is selectively settable to a shutter speed priority diaphragm automatic control mode, a diaphragm priority shutter speed automatic control mode, and a manual exposure control mode, includes a locking device arranged on a camera body for locking a diaphragm presetting member of an exchangeable lens at a specific position wherein indication of a f-number representative of an automatically controlled diaphragm aperture is allowed with a diaphragm of the exchangeable lens being held at its fully open aperture. An exposure mode change-over mechanism may be interlocked with the locking device such that the camera is set to the shutter speed priority diaphragm automatic control mode when the locking device is brought into its operative condition to lock the diaphragm presetting member at the specific position. The locking device can be brought into its inoperative condition to release the diaphragm presetting member by manipulation thereof, or in association with releasing of the exchangeable lens from its locked condition for removing the same from the camera body.

An object is to provide an immunoassay method requiring neither a solid-phase immobilization step nor a washing step, enabling quick and simple quantitative measurement of a target substance in a liquid phase and capable of visualizing an antigen. Such an object is attained by measuring the concentration of a target antigen present in a test substance by sequentially performing a step (a) of bringing an antibody light-chain variable region polypeptide and an antibody heavy-chain variable region polypeptide labeled with a fluorescent dye into contact with an antigen in a test substance in a liquid phase; or bringing an antibody heavy-chain variable region polypeptide and an antibody light-chain variable region polypeptide labeled with a fluorescent dye into contact with an antigen in a test substance in a liquid phase; a step (b) of measuring the fluorescence intensity of the fluorescent dye; and a step (c) of computationally obtaining the level of the antigen contained in the test substance with reference to a positive correlation between the concentration of the antigen in a liquid phase and the fluorescence intensity of the fluorescent dye.
