摘要： An exposure time controlling system includes a circuit for producing an APEX shutter speed signal which is applied to a first discriminator for briefly classifying the APEX shutter speed signal into four classes and also to a second discriminator for sub-classifying the APEX shutter speed signal. A pulse generator is provided for producing pulse signal having a frequency determined by the class and a counter is provided for counting the pulses for a number of times determined by the sub-class. A shutter mechanism is opened when the counter starts to count and is closed when the counter finishes counting the pulses.

摘要： In a photographic light measuring device, a light output signal representing light reflected from an object to be photographed is converted into digital signals. At least first and second setting means generate respective first and second digital set signals which are respectively variable in response to respective manual operations. Photographic exposure data signals are generated using the digital light signal and the first and second set digital signals such that indicating means can selectively indicate data commensurate with the first and second digital set signals.

摘要： An improved light measuring device that is capable of measuring light upon initialization from either a flash of light or a manual switch is provided. A sensor assembly can produce a light intensity signal and a change in the intensity of the light measured can be used to produce a first signal. A second signal can be produced by a manually operable member. A counter can be used to count the number of signals and to produce a preparing signal upon an initial signal counted and a start signal upon a subsequent signal counted. Measurement of the amount of light in the circuit can be initially enabled when the counting means counts the first signal and the actual light measurement can be started subsequently upon the counting means initiating a start signal. Various sequences of producing the pair of signals can be utilized to control the operation of the light measuring device.

摘要： An electronic flash device fires one or a pair of flash tubes sequentially for continuous shooting photography with a motor driven photographic camera, for substantially continuous illumination or for sequential illuminations at intervals, as well as fire the flash tube a single time for one shot photography. The flash device is provided with a main capacitor and an auxiliary capacitor which selectively energize the flash tube or tubes. The auxiliary capacitor is charged by the main capacitor and discharged to energize the flash tube for a small amount of flash light and shorttime restoration of the flash firing circuit. When a pair of flash tubes are employed, they are alternatively actuated for the sequential firing and one of them is actuated for the single time firing. The pair of flash tubes are coupled with each other through a commutation capacitor and switch elements for quick repetition of their firings.
