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.

摘要： An improved light measuring device for measuring flash light is provided, and includes a sensor for measuring the quantity of flash light to produce a flash measuring signal. A starting signal is produced upon a detection of the start of the flash emission to enable the sensor for measuring the quantity of flash light. The light measuring device is kept in an operative condition for a predetermined time period after it is manually turned on so that it is available to detect the start of any flash emission during that time period. A counter can be utilized to set the predetermined time period, and the counter can be reset in response to any light measuring operation.

摘要： In an instrument such as an electronic desk-top or pocket calculator, an exposure meter or the like, having a plurality of data-inputting switches in the form of a pushbutton switch, key switch, pressure or touch sensor switch, a control switch is provided for preventing inadvertent change of data stored or registered in the instrument. To this end, gates are interposed between the data inputting switches and a data storage member in the instrument. The instrument could alternatively include a microcomputer programmed to change its stored data in response to the operation of the input switches and to be prevented from changing the data upon operation of the control switch.
