摘要:
A camera having a pentagonal prism including a flash light emitting portion above the pentagonal prism and a driving force generator for generating a driving force to move the flash light emitting portion located beside the pentagonal prism. The driving force is transmitted to the flash light emitting portion by driving force transmitting means for moving the flash light emitting portion to change flash coverage.

An interchangeable camera system having a waterproof mount mechanism, and a photo-taking lens barrel and camera body used in the interchangeable-lens camera system. A large diameter part 2c which is provided on a lens-side mount surface 2a compresses a sealing member 6 in cooperation with a sealing surface 5c of a camera body 5 so that a gap between the lens-side mount surface 2a and the camera body 5 is sealed by the sealing member 6.

A cartridge holder being movable between a cartridge accommodating position where it is concealed within a camera body and a projecting position where it is exposed outside the camera body has a lower supporting member at its bottom for driving a film spool in a film cartridge inserted through an opening into the cartridge holder by engaging a lower end of the film spool, and an upper supporting member for engaging an upper end of the film spool. The upper supporting member is moved between its retracted position where it is retracted from the opening of the cartridge holder and its engaged position where it engages the film spool, its movement interconnecting with the movement of the cartridge holder between its cartridge accommodating and projecting positions.

A depth-of-field preview apparatus for a single lens reflex camera is provided with a display circuit responsive to a preview display signal generated by a control circuit with at least one of first and second switches being closed. The first switch is closed when an operating member is operated to an operated position and opened when the operating member is released to return to a non-operated position under a spring bias. In response to the closure of the first switch the control circuit generates the preview display signal and an electromagnetic device causes a diaphragm stop-down mechanism to stop-down a diaphragm. When the diaphragm is stopped-down to a preset aperture size, another electromagnetic device stops the diaphragm stop-down mechanism to set the diaphragm to the preset aperture size and at the same time closes the second switch. With the second switch being closed the control circuit continues to generate the preview display signal independently of the condition of the first switch, so that a preview display by the display circuit does not cease even if the operating member is released and accordingly the first switch is opened.

A camera has a motor, a camera mechanism driven by rotation of the motor, a detector for detecting the rotation direction of the motor, and a controller for driving the camera mechanism by energizing the motor in such a way that the motor rotates in a forward direction. To stop the motor, the controller energizes the motor in such a way that the motor rotates in a reverse direction and then, in response to a rotation direction inversion detecting output fed from the detector, energizes the motor in such a way that the motor rotates in the forward direction again for a predetermined period of time.

A cartridge holder being movable between a cartridge accommcodating position where it is concealed within a camera body and a projecting position where it is exposed outside the camera body has a lower supporting member at its bottom for driving a film spool in a film cartridge inserted through an opening into the cartridge holder by engaging a lower end of the film spool, and an upper supporting member for engaging an upper end of the film spool. The upper supporting member is moved between its retracted position where it is retracted from the opening of the cartridge holder and its engaged position where it engages the film spool, its movement interconnecting with the movement of the cartridge holder between its cartridge accommodating and projecting positions.
摘要:
A photographic camera which comprises an electronic flash unit for firing a flash light for illuminating a target object to be photographed when an image of the target object is desired to be exposed on a light senistive film, a preliminarily flash unit activated prior to the flash light fired by the electronic flash unit to emit a preliminary flash light necessary to cause the pupils of the target object to close, a manipulating unit for selecting a mode in which the preliminarily flash unit is activated, a determining circuit for determining the necessity of the preliminary flash light under a predetermined condition; and a display device for providing, on the basis of a result of determination made by the determining circuit, an indication that the preliminary flash light is necessary.

Disclosed herein is an on-line base sequencing apparatus, which is provided with electrophoresis tubes having a sheath flow part in each lower end thereof, which a sulfuric acid solution of pH 1.0 is continuously fed to form a sheath flow. The portions close to the outlets provided in the lower ends are irradiated with light which is close to 260 nm. In order to detect fluorescence components, each electrophoresis tube is provided with a detection system involving an interference filer for selecting that of 340 to 390 nm from the fluorescence components. Outputs of such four detection systems are successively identified, to determine base sequences.
摘要:
Camera comprises a focus detecting section for performing an object distance measurement, a flash for illuminating the object and controller for control the camera. The flash is activated to emit auxiliary light so as to assist a focus detection when a focus detection is performed by the focus detecting section, and is activated to emit light for illuminating the object during an exposure of photographing. Also, camera is capable of a self-timer photographing, and indicates the self-timer photographing by emitting the flash light during the self-timer operation. The flash light is used both as the auxiliary light for a focus detection and light for indication of the self-timer operation.

A camera having a built-in electronic flash device and a detachable electronic flash device, provided with a detecting sensor for detecting photographing condition, which judges whether or not a red-eye phenomenon caused by a reflection of flash light on human retinae tends to occur. In accordance with the judgment, activation of both flash devices are controlled.
