Abstract: An electronic camera comprises an imaging optical system, image-pickup means for converting an optical image formed by the optical system into an electric image signal, memory means capable of recording the electric image signal, trigger means adapted to be actuated for transferring the electric image signal corresponding to a still optical image to the memory means and means for inserting data into the electric image signal thus transferred. The inserting means comprises means for replacing a part of the recorded electric image signal with "framed" or "unframed" data.

Abstract: Electronic camera comprises an image taking unit and a memory unit connected detachably. The image taking unit generates image signals corresponding to an object. The image signals are transmitted to the memory unit to be stored therein. The memory unit is detached from the image taking unit and connected to an external memory device such as a video tape recorder. The image taking unit has a monitor which can display the image signals in visual form before recording them in the memory unit.

Abstract: A device capable of containing at least one planar battery having a positive electrode and a negative electrode and capable of supplying a power to a circuit when the battery has been completely contained includes a plurality of terminals for contacting the positive electrode and the negative electrode, respectively, of the battery when completely contained, means for holding each of the terminals, the holding means holding at least one of the terminals movably between a first position and a second position and wherein the movable terminal, when in the first position, contacts neither of the positive electrode and the negative electrode and, when in the second position, can contact one of the electrodes, and means for moving the movable terminal to the second position in response to the containment of the battery.

Abstract: An electronic photographic camera includes an imaging optical system operable to be focused to an object to be photographed, a solid state imaging sensing device including a plurality of light-receiving elements disposed in the imaging plane of the imaging optical system and capable of producing a charge corresponding to the quantity of incident light and accumulating the charge therein, first transfer means having a first output terminal and adapted to transfer the charge accumulated in each of the elements separately to the first output terminal, and second transfer means having a second output terminal and adapted to transfer the charges produced in some or all of the elements collectively to the second output terminal, and metering means for measuring the brightness of the object from the charge transferred by the second transfer means.
