Abstract: An interchangeable-lens camera is usable with a flash unit which stops the flash on the basis of the object distance and transmits a signal corresponding to a required aperture value. The camera includes a diaphragm control that responds to the light passing through the maximum aperture of the interchangeable lens and corrects for a particular maximum aperture. A selector causes the diaphragm control to respond either to the light or the signal transmitted by the flash and a switch aborts the maximum aperture connection during flash photography.

Abstract: 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.

Abstract: A filter for compensation of spectral sensitivity is provided in front of a light receiving element through a light shielding tube. A light source emitting such light as having wave length characteristics which fall within a sensitive wave length zone of the light receiving element yet fall outside of transmitting wave length zone of the filter is provided between the filter and the light receiving element. Light from outside irradiates the light receiving element through the filter while light from the light source is so controlled as irradiating the light receiving element but not leaking through the filter to outside, so that the light from the light source can irradiate the light receiving element without any relationship with the irradiation of outside light on the light receiving element.

Abstract: In the disclosed arrangement, an energy storage device such as a capacitor is discharged through a flash lamp. A sensing device produces a signal when the storage voltage is sufficient to fire the lamp. A switchover device normally permits the shutter and exposure aperture to be set for daylight operation, but automatically responds to the signal to switch the shutter speed and the exposure aperture to suitable values for flash operation.

Abstract: 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.

Abstract: An exposure control system for a camera capable of deriving more reliable and accurate exposure values over an extended range of scene luminance despite variation of the ambient temperature of the system than was previously possible. The exposure control system is characterized by the use of a photovoltaic cell and a logarithmic converter connected thereto in combination with a voltage stabilizer for providing output current signals of which the values are independent of temperature to the automatic camera diaphragm aperture regulating mechanism. The logarithmic converter consists of an operational amplifier with a feedback diode connected between the input and the output of the operational amplifier. The voltage stabilizer connected to the operational amplifier comprises a plurality of transistors selected to have such characteristics that the temperature dependance components of the luminance versus output signal response characteristic of the photovoltaic cell and the logarithmic conversion of the converter are cancelled by the temperature dependence component of the voltage supplied from the voltage stabilizer.

Abstract: The device includes a permanent magnet for attracting a movable iron armature. A pair of elongated rectilinear magnetic bodies have planar pole faces at one end facing the iron armature, and the permanent magnet is sandwiched between these two magnetic members intermediate their ends, with the permanent magnet extending perpendicularly to the magnetic members. Respective magnetizing windings embrace each magnetic member between the permanent magnet and the pole faces of the members, to produce a magnetic flux in the magnetic members opposing the flux provided by the permanent magnet so as to release the iron armature. In one embodiment of the invention, the other ends of the members, projecting beyond the permanent magnet, are angled to face each other to provide an air gap therebetween. In a second embodiment of the invention, the magnetic members or yokes have respective second windings thereon, beyond the permanent magnet, and the ends of these yokes, beyond the second windings, are formed with planar pole faces for operative association with a second iron armature. Both iron armatures are spring biased to disengage the magnetic yokes or members. As the permanent magnet engages the yokes intermediate their ends, the magnetic flux path due to the magnetizing windings does not include the permanent magnet and therefore an effective armature releasing magnetic flux can be provided with only a relatively small current supplied to the magnetizing windings.
