摘要:
An apparatus capable of using a film cartridge in a manner that a lead portion of a film contained in the cartridge is fed out therefrom by the film thrusting, wherein a controller judges that an initial loading is not executed normally when a perforation is not detected although a fed film amount on an initial loading reaches a first predetermined amount, and stops a detector from detecting a perforation until the fed film amount reaches a second predetermined amount which is less than the first. Thus, a detector does not wrongly detect a notch on a film's lead portion as a perforation, and a leading frame is fed normally with a reliable judgment on an initial loading.

A camera loadable with a film regularly formed with perforations along a length of the film and provided with exposure areas and magnetic recording areas arranged with reference to the perforations, the camera includes: a perforation detector which detects a perforation; a recording device which records magnetic data in a magnetic recording area; and a controller which controls the recording of the recording device in accordance with a detection of the perforation detector. The camera can securely perform a proper magnetic recording and recording of a photographed image within a set exposure area.

A camera having a box-form cover member slidable on a camera body between a closed position and an opened position. The camera further has a heat releasing member that releases heat generated within the camera body, into a space formed between the camera body and the cover member.
摘要:
An apparatus using a film cartridge in a system that a leading portion of a film contained in a cartridge is thrust to be conveyed from the cartridge, wherein an indicator showing an exposure condition is reset to an original state when an initial loading, which is executed on a film cartridge loading in an apparatus, is not executed normally, and the film is rewound, thus, it indicates "unexposed" when a new film cartridge is loaded. While, when a winding up operation is not executed normally during a photographing, a film is rewound and an indicator showing an exposure condition, is set so as to indicate that the film is exposed. Thus, it prevents from causing a double exposure.

A small-sized photographing apparatus in which a single display device performs both of a viewfinder and monitor display. The apparatus includes a body having a viewfinder window; the display device, the display surface of which can be observed from outside of the body; a pair of reflection mirrors inside the body; and a member for moving one of the reflection mirrors between a reflection position at which a beam of light from the display surface of the display device is reflected so that the beam is guided towards the viewfinder window, and a non-reflection position which is different from the reflection position.

A camera body to which one of a plurality of interchangeable lenses is selectively attached is provided with: a shake detector 31; a shake compensation mechanism 32; and a controller 30 that compensates for the camera shake by driving the shake compensation mechanism based on the output from the shake detector. The controller 30 has a detector and a selector. The detector communicates with the attached interchangeable lens 20 and determines whether the interchangeable lens 20 itself has a shake compensation mechanism or not. The selector selects, when the detector determines that the interchangeable lens 20 has a shake compensation mechanism, both or one of the shake compensation mechanism of the camera body 10 and the shake compensation mechanism of the interchangeable lens 20 according to a predetermined condition as a compensation mechanism to be used for camera shake compensation.

A digital camera comprises an electronic view finder (EVF) for electronically displaying an image of a subject and a movable monitor. The movable monitor is slidable along guide grooves and movable between a first position in which the EVF is covered with the movable monitor and a second position in which the EVF is not covered. By a sensor for position detection, when it is detected that the movable monitor is in the first position, no image is displayed on the EVF but an image is displayed on the movable monitor. When it is detected that the movable monitor is in the second position, no image is displayed on the movable monitor but an image is displayed on the EVF. Consequently, power can be saved, and when the movable monitor is in the first position, adhesion of dusts and dirt onto the display face of the EVF can be decreased.

A digital camera having a taking lens, a finder for viewing light transmitted through the taking lens, an image sensing element for optoelectrically converting light which passes through the taking lens, a light splitter capable of changing transmittance and dividing the light transmitted through the taking lens to the image sensing element and the finder, a light splitter driver for driving the light splitter to a position to split the light between the image sensing element and the viewfinder when viewing and driving the light splitter to retract a position for directing the light only to the image sensing element during photography, and a controller for controlling the light splitter to a semi-transparent state to direct light to the image sensing element and the viewfinder when viewing and controlling the light splitter to a blocking state during photography.
摘要:
An object of the present invention is to provide a method for manufacturing an optically active menthol having fewer steps, which generates less environmentally polluting waste because a catalytic reaction is involved in all of the steps, and is capable of saving a production cost. The present invention relates to a method for manufacturing an optically active menthol, including the following steps: A-1) asymmetrically hydrogenating at least one of geranial and neral to thereby obtain an optically active citronellal, B-1) conducting a ring-closure reaction of the optically active citronellal in the presence of an acid catalyst to thereby obtain an optically active isopulegol, and C-1) hydrogenating the optically active isopulegol to thereby obtain an optically active menthol.
