摘要： The disclosed camera power control devices operate with a camera in which a first switch responds to initial movement of a shutter release member, and a second switch responds to further movement of the release member. In the power control device, turning the first switch on energizes the light metering and display circuits, and turning on the second switch supplies an exposure control circuit such as a shutter control circuit with electrical energy. The power control device is provided with an electrical timer circuit, and a selection arrangement operates to selectively actuate the timer circuit when the release member is returned to its rest position and the first switch changes is state from ON to OFF. During a period of time determined by the timer circuit, power continues to be supplied to operate the light metering and display circuits.

摘要： A co-ordination control system for a camera and a motor drive unit with separate electrical power sources one of which has a higher voltage than the other. The system is provided with an interface circuit including two switching elements arranged to cooperate with a common release button and connected between the circuitries of the camera and the unit so that the higher voltage of the source in the unit is prevented from being applied to the circuitry of the camera. For remotely controlled photographic purposes, the system is further provided with a control circuit for actuating these two switching elements in time-displaced relation to each other.

摘要： A shutter releasing system controlling apparatus for a self developing type instant camera equipped with a motor-driven treating liquid spreader. The shutter releasing operation is prevented not only when the battery is too low, but also during the motor driving operation of the treating liquid spreader. On and off timing control of the motor is correctly and safely performed by the shutter releasing system.

摘要： In the automatic exposure control camera disclosed, a memory has data stored therein on the basis of the object brightness and is periodically reset by a reset device to obtain new brightness data, while an exposure control controls exposure on the basis of the data. A signal device ordinarily produces a first signal but locks into a second signal after an external operation. A gate arrangement between the memory and the reset device passes reset signals to the memory, but responds to the second signal to inhibit the reset so as to latch the content of the memory.

摘要： Electronic flash apparatus for a camera having automatic focusing with sonic ranging has a charge control system which inhibits charging of the flash tube capacitor during at least the automatic focusing operation of the camera. The flash apparatus thus schedules capacitor charging to occur at times other than the sonic ranging for automatic focusing, and thereby avoids the likelihood that spurious radiation from the capacitor-charging oscillator interferes with the sonic ranging operation.

摘要： An automatic exposure camera, for example a TTL light measuring camera including a light measuring circuit, an exposed condition indicating circuit, and a light information storage circuit includes a normally open semiconductor switch connecting the circuits to a source of energizing current and actuated to a closed condition in response to a conductor being coupled across its control input terminals, at least one of which is defined by the camera manually operated shutter release members. In one form the switch input terminals are connected to mutually insulated coaxial members forming the release button and exposed at their top and in another form such terminals are connected respectively to the camera body and an electrically insulated top exposed portion of the release member. Thus, merely touching the release button by the photographer energizes and activates the respective circuits.
