摘要： An electronic flash apparatus is provided with a display element positioned in the view-finder of a photographic camera so that the operator is immediately aware if the flash tube has been fired in response to the closure of the synchronous switch. The light emitting operation of this display element is controlled by use of a signal generator arranged to be responsive to the occurrence of discharge through the flash tube of the flash apparatus. With this apparatus, therefore, the operator may rely upon the appearance of this display element to insure that the firing is effected by the flash apparatus even when the object-to-camera distance is relatively small.

摘要： A shutter control circuit which normally responds to ambient light switches automatically to a flash mode in response to a charge signal from a flash unit. The light flash eliminates the charge signal. To prevent the absence of a charge signal from returning the shutter to daylight control, a shutter closing signal is generated before a flash synchronizing contact is closed and hence before the charge signal ends. However shutter closing action is then started only after a delay that provides time for the flash to occur when the shutter is fully open.

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.

摘要： A temperature compensating device for devices comprising semiconductors. The temperature compensating device comprises a temperature compensating circuit, such as a circuit including a diode, and a current control circuit which adjusts the quantity of the electric current flowing through the temperature compensating circuit. The temperature characteristic of the temperature compensating circuit is mutually compensatory with that of the output of the device comprising semiconductors. When the temperature characteristic of the output of said temperature compensating circuit differs from that of the output of such semiconductor device, the current control circuit causes a current which corresponds to the difference between the temperature coefficient of the compensating circuit and that of the semiconductor device to flow through the temperature compensating circuit, so that satisfactory temperature compensation can be accomplished.

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： The present invention relates to a device for measuring light incident on an image forming optical system, making use of a plural number of the diffraction element. The plural number of the diffraction elements are respectively provided in the optical path of the image forming optical system. Further the plural number of the diffraction elements respectively present a certain predetermined area. The plural number of the diffraction elements, seen along the direction of the optical axis of the image forming optical system, are substantially only partially overlapped with respect to each other. The light beam incident on a diffraction element is divided into a non diffracted light beam and a diffracted light beam. Thus diffracted light beam is directed toward the light detecting means so as to be measured while the non diffracted light beam advances along the above mentioned optical axis. Consequently at the part at which the diffraction elements overlap each other, the non diffracted light beam led out of the preceeding diffraction element again enters the following diffraction element. This light beam is again divided into a non diffracted light beam and a diffracted light beam by means of the following diffraction element. The diffracted light beam is measured by a light detecting means in the same way as in the above mentioned case, while the non diffracted light beam advances along the above mentioned optical axis. Thus the light beam which passes through the overlapping parts is measured a plural number of times.

摘要： In an electromagnetic release for a camera a normally de-energized electromagnet is coupled with unitarally joined elongated pole pieces, and when energized, generates a magnetic flux opposing the magnetic flux of a permanent magnet. A moveable, magnetizable armature adjacent corresponding ends of the pole pieces is normally attracted by the pole pieces as a result of the flux of the permanent magnet when the electromagnet is deenergized. The permanent magnet is positioned between the pole pieces. A spring biases the armature to disengage it from the faces of the pole pieces.
