摘要： The disclosed automatic flash photography apparatus operates with a camera having a shutter in which a diaphragm blade serves as a shutter blade, and the diaphragm diameter is varied by varying the time interval from the moment its blades start opening till the moment they start closing. A switch switches over between separate time constant circuits, one for artificial-light photography, the other for natural-light photography. For flash photography, a resistor which is variable in response to the distance from a light source to an object and the film sensitivity controls the time constant circuits for closing the diaphragm blades. Thus a flash device is illuminated and the amount of light passing the diaphragm aperture is established.

摘要： A shutter control circuit which normally responds to ambient light switches automatically to a flash mode in response to a charge signal from a flash unit. The light flash eliminates the charge signal. To prevent the absence of a charge signal from returning the shutter to daylight control, a shutter closing signal is generated before a flash synchronizing contact is closed and hence before the charge signal ends. However shutter closing action is then started only after a delay that provides time for the flash to occur when the shutter is fully open.
摘要翻译：响应于来自闪光单元的充电信号，通常响应环境光的快门控制电路自动切换到闪光模式。闪光灯消除了充电信号。为了防止没有充电信号使快门返回到日光控制，在闪光同步触点闭合之前并且因此在充电信号结束之前产生快门关闭信号。然而，只有在快门完全打开时，闪光灯提供时间的延迟之后才开始快门关闭动作。

摘要： An electronic flash apparatus is provided with a display element positioned in the view-finder of a photographic camera so that the operator is immediately aware if the flash tube has been fired in response to the closure of the synchronous switch. The light emitting operation of this display element is controlled by use of a signal generator arranged to be responsive to the occurrence of discharge through the flash tube of the flash apparatus. With this apparatus, therefore, the operator may rely upon the appearance of this display element to insure that the firing is effected by the flash apparatus even when the object-to-camera distance is relatively small.
