摘要： The present invention relates to a light-sensing circuit used in a so-called light regulating type flash device to automatically control the amount of flash emitted. In the present invention, a flash photographing with an appropriate exposure is done, securing such flash amount as providing appropriate exposure always regardless of the position of an object in a photographing frame. This is done by making light-sensing for each of different zones independently using a plural number of light-sensing circuits for stopping the flashing by the output of the one light-sensing circuit reaching a prescribed level of output from the different light-sensing circuits.

摘要： The present invention relates to a device for flash light photography and, more particularly, to a device for flash light photography for adjustable light stroboscope. A major feature of the present invention is that the adjustable light condition of the stroboscope is rendered to be adjusted, based on the film speed and diaphragm value, independently of each other. Thus, when the film speed is made high, the responsive distance for light adjustment is elongated.

摘要： A device for automatic control of the quantity of light from an electronic flash tube including a silicon controlled rectifier connected in series with the flash tube, a circuit for applying a reverse voltage between the main electrodes of said silicon controlled rectifier so as to open said rectifier, and a switching element connected between said reverse voltage applying circuit and said silicon controlled rectifier. Responsive to the output signal from the reverse voltage applying circuit, the switching element short-circuits the gate electrode and cathode of the rectifier. With this arrangement, it is possible to decrease the capacity of a commutation capacitor constituting part of the reverse voltage applying circuit.

摘要： In a camera provided with a day-light exposure range and with a flash exposure range, an automatic exposure control system for controlling the iris of the camera in accordance with a computed exposure value and a preselected shutter time is associated with a flash exposure time range bracketing device in order to insure that the formation of a correct flash exposure aperture is effected with automatic selection of one of the bracketed exposure times despite an accidentally incorrect setting of the shutter dial of the camera which may be encountered particularly when the day-light exposure range is to be left for the flash exposure range without the necessary manipulation of the shutter dial therefor. The bracketing device of the present invention comprises three timing circuits in combination with a selector responsive to the position of the shutter dial for selecting either the first, or the second, or the third timing circuit for cooperation with an electronic switch controlling the period of actuation of the camera shutter when the shutter dial is set either within, or on the faster side of, or on the slower side of a possible flash exposure time range respectively, whereby the resultant actuation period is equal to either the shutter time preselected on the shutter dial, or the faster limit of, or the slower limit of the flash exposure time range respectively.

摘要： In an instant, self-developing, and folding camera, a built-in flash unit is disabled as long as the camera is folded. According to another aspect, the flash is disabled after each photograph until the feed motor that drives the film during development has completed its operation. A collapsible bellows forms a dark space between first and second housing sections. When the bellows are folded the flash is drawn to the first section by coupling means. When the bellows are extended the coupling means draws the flash into an operative position.
