摘要： In cameras, a magnetic mechanism is used to control various camera operations. In order to reduce current consumption in supplying such magnetic mechanism, the present invention provides an improvement over known designs. The present inventive system for the magnetic mechanism thus presents a second reset member beside the normal reset member for releasing the current supply to the magnetic mechanism. If the current is continued to be supplied to the above mentioned magnetic mechanism by mistake, the above mentioned second reset member interrupts the current supply to the above mentioned magnetic mechanism instead of the normal reset member. In this way, the useless consumption of the battery can be avoided.

摘要： An automatic exposure control apparatus for controlling the diaphragm of the camera in accordance with the preselected shutter time and the exposure value, in which a digital-to-analog converter having a counter responsive to the number of pulses supplied from a clock pulse generator through a gate produces a time variable output capable of attaining a certain level dependent upon the preselected shutter time and a light value as photoelectrically sensed, that is, an exposure value and, which is detected by a first comparator. The output of the first comparator is applied to the gate, so that the converter is set to memorize the exposure value therein. As the diaphragm presetting ring is moved from the maximum to minimum aperture position with production of a time variable output from a signal generator associated therewith, a second comparator responsive to the attainment of the time variable output of the signal generator to a level dependent upon the final output of the set converter produces an output which is applied to arresting means for the diaphragm presetting ring. This results in automatic adjustment of the position of the presetting ring. At the time the presetting ring begins to move, the diaphragm driving means is actuated causing the diaphragm means to be brought into engagement with the ring. Thus, an effective exposure aperture is established in the diaphragm means.

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.
