    • A camera comprises an exposure meter having a pointer deflected to a position dependent upon the brightness level of an object to be photographed, a scanning mechanism actuated by a camera release to scan the position of the deflected pointer with the scanning result being introduced to a lens aperture mechanism, an automatic focus adjusting device actuated by the camera release to control the focusing of an objective lens in accordance with a photoelectrically sensed distance from the camera to the object, and a control mechanism. Since the photoelectric elements in measuring the object distance have a relatively long time lag, the control mechanism functions upon actuation of the camera release to defer the actuation of the scanning mechanism and the autofocusing device, pending completion of the detection of the object distance. In this manner, an exposure setting accurately corresponding to the prevailing lighting conditions is obtained. When the light value is too low to assure the satisfactory operation of the automatic focus adjusting device, the camera may be switched to the flash mode where the objective lens and the aperture mechanism are automatically set in a pan-focus condition in response to actuation of the camera release.
    • 相机包括曝光计,其具有偏转到取决于要拍摄的对象的亮度水平的位置的指针,由相机释放致动的扫描机构,以扫描结果被引入到透镜的扫描指示器的位置 光圈机构,由相机释放致动的自动对焦调节装置,以根据从照相机到对象的光电感测距离来控制物镜的聚焦,以及控制机构。 由于测量对象距离的光电元件具有相对较长的时间滞后,因此在完成对象距离的检测之前,控制机构在驱动相机释放时起作用以推迟扫描机构和自动对焦装置的致动。 以这种方式,获得与主要照明条件精确对应的曝光设置。 当光线值太低而不能确保自动聚焦调节装置的令人满意的操作时,相机可以切换到闪光模式,其中物镜和光圈机构响应于主动作被自动设定在泛焦条件 相机发布。

    • A camera having an electronic flash unit either incorporated therein or removably attached thereto is provided with a flash mode selector and a flash energy supply control switch both arranged to be rendered operative when the shutter cocking lever is pulled from the retracted position to an initial position effective for shutter cocking operation, and, upon detection of occurrence of a lower light value beyond an automatically operating daylight diaphragm aperture range, to be simultaneously closed in automatic response to an actuation of a shutter release trigger in excess of a normal stroke length. This is done while still preventing the shutter from running. When the voltage on a storage capacitor reaches a trigger level for the flash tube in a time interval measuring from the closure of the switch, a flash exposure diaphragm aperture is automatically formed depending upon the flash exposure value and the voltage of the storage capacitor. When the shutter cocking lever is retracted, the switch is opened to prevent accidental consumption of the electrical energy of the power source.
    • 具有并入其中或可移除地附接到其上的电子闪光单元的相机设置有闪光模式选择器和闪光能量供应控制开关,其被设置为当快门推杆从缩回位置被拉动到初始位置时有效 用于快门启动操作,并且在检测到超出自动操作的日光光阑孔径范围的较低光值的发生时,在对超过正常行程长度的快门释放触发器的致动的自动响应中同时关闭。 这样做同时仍然防止快门运行。 当存储电容器的电压在从开关闭合开始的时间间隔内达到闪光管的触发电平时,根据闪光曝光值和存储电容器的电压,自动形成闪光曝光光圈。 当快门推杆被缩回时,开关打开以防止意外消耗电源的电能。
