    摘要： A photographic camera of the type including a piezo-­electric actuating element (Bil) driven by energy accumulated in a capacitor (C2) for actuating a shutter wherein the piezo-electric element (Bil) operates in stability to assure accurate appropriate opening and closing operation of the shutter of the camera and the capacitor (C2) is charged up rapidly to allow subsequent photographing operation to be done in a minute. In the camera, a charged voltage of the capacitor (C2) is checked several times to determine if it is sufficient to assure proper operation of the piezo-electric element (Bil), and if a then required level is not reached, then the capacitor (C2) is charged to the required voltage. While the capacitor is being charged, charging of a capacitor for a flash is inhibited. For operation of the shutter, a negative voltage is first applied across the piezo-­electric element (Bil) to set the same to its fixed home position, and then a positive voltage is applied to move the shutter from the home position to a predetermined opening position, whereafter the negative voltage is applied again to return the shutter to its initial position rapidly. The position of the shutter is also checked to assure proper operation of the camera.

    摘要： A photographic camera having a photographic lens including a device for selecting a real focal length photographing mode in which a normal range in a frame of a film will be printed on a photographic paper and a pseudo focal length photographing mode in which a range smaller than the normal range in a frame of the film will be printed on a photographic paper, a device for measuring light coming from an object to be photographed and outputting a signal corresponding to the luminance of the object, and a device for illuminating the object with flash light emission, The camera further includes a device for outputting a signal for activating the illuminating device when the output signal from the measuring device shows that the luminance of the object is lower than a predetermined level and a device for altering the predetermined level in response to a selection of the selecting device.

    摘要： A photographic camera having a real focal length photographing mode and two kinds of a first and a second pseudo focal length photographing modes. In the first pseudo focal length photographing mode, the photographic camera is capable of specifying a scope for printing narrower than the scope in the real focal length photographing mode. The photographic camera has a function (S5, S6) for selecting either of the real focal length photographing mode and the first and second pseudo focal length photographing modes in order to out­put a mode signal in accordance with the selected mode, a function (LM) for measuring a brightness of an object to output a signal of the measured light in accordance with it, a function (DX) for outputting a signal in accordance with a film sensitivity and a function (CPU, MD, RMG, SMG) for calculating an exposure value in accordance with the signals of the mode, measured light and film sensitivity and also for rectifying the aperture to the open side in the second pseudo focal length photographing mode rather than in the first pseudo focal length photographing mode.
