    Abstract: In a photographic camera in which the diaphragm aperture for exposure is preset, and the shutter speed for the thus preset diaphragm aperture is automatically controlled with respect to the brightness of a photographic object when at the fully opened diaphragm aperture and also in accordance with the film sensitivity, an automatic exposure control device is so programmed that prior to the commencement of exposure, a determination is made whether the aforesaid automatically controlled shutter speed is higher or lower than a predetermined lower boundary value. If the shutter speed to be automatically controlled is lower than the predetermined lower boundary value, the diaphragm will be maintained in fully open position, without being set to the aforesaid predetermined diaphragm aperture, so as to automatically obtain the proper shutter speed in accordance with the brightness of a photographic object and the film sensitivity, whereby the exposure is then effected.

    Abstract: The purpose of the present invention is to make the thickness of the photoconductive semiconductor element body as flat and thin as possible so that it may easily be built into a camera or other instruments, and also to increase the resistance against vibration and shock. This photoconductive semiconductor element body of the present invention consists of a base frame onto which is attached fixedly an insulating thin plate with the photoelectric conductive layer on top and two cuts in its edge, and a window frame, with a transparent window, whose periphery comes on top of the base frame, and the lead material that makes contact with the photoelectric conductive layer at the said cuts and is closed and made airtight inside the base frame by a hard glass.
