    摘要： A power supply circuit for a camera wherein a detection circuit which detects the voltage of a power source is provided for supplying an electric power to the electric circuit of the camera only when the detected voltage is above a preset value.In the power supply circuit, the power supply is controlled by a detection output obtained after a voltage detecting action is performed in a stable condition by the detection circuit. The power source voltage is detected in a manner suitable for the characteristic of the battery employed. Further, the voltage detection is performed only momentarily to prevent unnecessary power consumption for voltage detection.

    摘要： A camera detects which of a number of operating modes is dialed into a flash unit by sensing the current level produced by a source. In response to dialing of a daylight EE mode, the camera measures the brightness of the object to be photographed and conforms the diaphragm aperture to a preselected shutter speed. In one flash mode the flash unit transmits desired aperture and shutter speed data suitable for flash and the camera automatically responds. In another mode, the shutter speed is set into the camera and the camera automatically controls the diaphragm aperture on the basis of data transmitted by the flash unit.

    摘要： An automatic winding up device for a camera, in which a device for detecting the winding up completion signal supplied from the camera body as well as a delay device starting to operate by the detection of the winding up completion signal by the detecting device are disclosed. These devices operate in such a manner that the current supply to the winding up motor is maintained during the operation of the delay device. This acts to overload the motor for a certain time determined by the delay device after the completion of the winding up operation and overloads the winding up mechanism of the camera body. The current supply to the motor is interrupted after lapse of a time determined by the delay device so as to stop the motor. The winding up member is driven in the reversed direction by the reaction of the overload exercised on the winding up mechanism so that the load exercised on the camera is released at the termination of the winding up operation.

    摘要： In a camera provided with a day-light exposure range and with a flash exposure range, an automatic exposure control system for controlling the iris of the camera in accordance with a computed exposure value and a preselected shutter time is associated with a flash exposure time range bracketing device in order to insure that the formation of a correct flash exposure aperture is effected with automatic selection of one of the bracketed exposure times despite an accidentally incorrect setting of the shutter dial of the camera which may be encountered particularly when the day-light exposure range is to be left for the flash exposure range without the necessary manipulation of the shutter dial therefor. The bracketing device of the present invention comprises three timing circuits in combination with a selector responsive to the position of the shutter dial for selecting either the first, or the second, or the third timing circuit for cooperation with an electronic switch controlling the period of actuation of the camera shutter when the shutter dial is set either within, or on the faster side of, or on the slower side of a possible flash exposure time range respectively, whereby the resultant actuation period is equal to either the shutter time preselected on the shutter dial, or the faster limit of, or the slower limit of the flash exposure time range respectively.

    摘要： A camera which permits change-over between different light measuring systems is disclosed. The camera includes a first light measuring element which measures light coming from an object to be photographed and an operational amplifier responsive to the element. A light measurement information producing circuit is included for producing a light measurement information signal for exposure computation. A change-over device is connected between the light measurement information producing circuit and the operational amplifier. The change-over device is arranged to be shiftable between a first position wherein the operational amplifier is connected to the light measurement information producing circuit and a second position wherein the operational amplifier is not so connected. An accessory device is attachable to the camera body. The accessory device includes a second light receiving element for measuring light from the object within a light measurement range different from that of the first light receiving element and another operational amplifier responsive thereto. A terminal is responsive to the signal from the latter operational amplifier. The terminal is disposed at the second position of the change-over device so that the signal from the latter operation is applied to the light measurement information producing circuit when the change-over device is in this position.
