摘要:
A framing mirror provided on the front part of a camera for enabling observation of the range of the scene to be photographed from the front of the camera is used for various displays by a liquid crystal display device. Various operation modes are set by a mode selection member and the state of the display portion of the liquid crystal display device arranged in front of the framing mirror changes in accordance with the set operation mode to effect various displays. In at least one of the operation modes the whole display portion of the liquid crystal display device becomes transparent, whereby it is possible to observe the framing mirror from the front of the camera. Alternatively, the framing mirror has a transparent portion at a marginal position and the liquid crystal display device is arranged behind the transparent portion so as to be observable from the front of the camera. The liquid crystal display device displays the same data as displayed by another liquid crystal display device which is arranged behind the framing mirror, for recording data on a photographic film.

A disc camera for use with a disc film cartridge includes upper and lower camera walls spaced from one another by a distance less than the height of the cartridge housed in a cartridge chamber. The upper wall is formed with an opening which allows a part of the cartridge housed in the cartridge chamber to project therefrom. A frame is formed in the cartridge chamber so as to be fitted with an exposure aperture of the cartridge when a rear cover of the camera is closed. The frame serves to prevent exposure of a film in the cartridge to unwanted light. A covering member which protects the projecting part of the cartridge against impact which might be applied thereto also prevents entry of dust into the cartridge chamber.The opening may be formed on a lower camera wall or on both of the upper and lower camera walls.

A single lens reflex camera in which the diaphragm aperture is stopped-down to a preset position before measuring the image light for use in the automatic exposure control mechanism of the camera. A mirror, which is provided in the camera along its optical path, is movable between a viewing position and a retracted photographing position. The camera has a focal plane shutter with two curtains. Upon exposure, the curtains travel in sequence in the same direction in which the mirror is retracted. Initiation of the movement of the first curtain begins before the mirror is fully retracted, thereby enabling the time lag between a shutter release operation and exposure to be reduced.

A camera for use with a disk film having a take lens window provided in the front side of a parallelepipedal housing closer to one lateral side thereof and a mirror device disposed at the center of the front side adjacent the window for observing the object. The mirror device is variable in its inclination to correct the parallax due to a variation in the distance of the object and has framing marks for indicating the field of view of the lens which differs with the object distance. The mirror device further has a coverage recognition sign which is observable only from a predetermined position within the coverage where an image of the object can be accurately observed on the device.
摘要:
A mechanism for automatically controlling the diaphragm aperture of a single lens reflex camera in response to scene brightness, has a photo-electric element disposed within camera body outside the photographic light path to receive light coming from the scene through the objective and diaphragm aperture and reflected from light reflective surfaces of shutter curtain and/or film. After the reflex mirror has retracted from its viewing position, the diaphragm is gradually stopped down with the photo-electric element receiving scene light therethrough until a diaphragm control circuit detects a suitable diaphragm aperture and interrupts the stopping down operation. Exposure time may be controlled by an electric circuit in accordance with the output of the photoelectric element receiving scene light through the diaphragm aperture adjusted by the diaphragm control circuit.
摘要:
An exposure control mechanism for a camera which includes a light measuring circuit having a photosensitive element disposed for receiving scene light reflected at substantially the entire area of both the surface of a film and a leading curtain of a focal plane shutter after the light has passed through an objective and a diaphragm. An operable member is provided for moving a light restricting member from a non-operative to an operative position where the member respectively permits the scene light reflected at the entire area or the scene light reflected at a small predetermined area of the surface to be received by the photosensitive element. An alternative light measuring circuit has a plurality of photosensitive elements respectively disposed for receiving the scene light reflected at different small predetermined areas of the surface. In this case, switches are provided for selectively activating the photosensitive elements of the light measuring circuit.

A digital camera of the present invention includes a microcomputer 110 having a live view mode controlling so that image data generated by a CMOS sensor 130 or image data obtained by subjecting the image data generated by the CMOS sensor 130 to predetermined processing is displayed on a liquid crystal monitor 150 as a moving image in real time, wherein when a release button 141 receives an instruction regarding start of an autofocus operation in a live view mode, the microcomputer 110 controls a movable mirror to enter an optical path to measure by an AF sensor 132, and thereafter, allow the movable mirror to retract from the optical path to return the digital camera to the live view mode. Due to this configuration, in a digital camera that includes a movable mirror and is capable of displaying a subject image in a live view through an electronic viewfinder, the operability thereof can be enhanced.
摘要:
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.
