摘要： An automatic shutter control system for a camera includes a continuous rotatable motor coupled to a pair of separately engageable electromagnetic clutches. The clutches are respectively operable, when engaged, for releasing the shutter to commence exposure and for winding up the shutter after exposure has terminated. When camera operation is initiated, the first clutch is engaged to release the shutter and to trigger the start of a manually selectable exposure duration. At the conclusion of the selected duration, the first clutch is disengaged and the second clutch is engaged to begin the wind-up of the shutter. An inertial sensor on the motor terminates the wind-up operation and disengages the second clutch when the increased torque on the motor from wind-up reaches a predetermined value. Where continuous operation of the camera is desired, the completion of wind-up triggers an interval control circuit which effects the reengagement of the first clutch after a prescribed time delay to initiate another cycle of operation. Facilities are provided for overriding the manually set exposure duration whenever the required film exposure time exceeds such set duration to automatically delay the completion of the shutter release operation until the completion of the exposure.

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： A control system for a camera controls a shutter release operation electromagnetically. A signal generating circuit produces a switching signal for operating a switching circuit which supplies current to a control circuit for a camera. The signal generating circuit is in a condition to always produce a switching signal when a camera operation member is set to normal photographing modes other than the bulb photographing mode, and is out of condition to produce the switching signal during the time between actuation of a magnet and termination of the shutter opening operation. The closing operation of the shutter is checked by means of a mechanical control member during the release when the camera operation member is set in the bulb photographing mode.

摘要： A focal plane shutter adapted for use in a single lens reflex camera and having front and rear curtains with respective charge control gears to be operated in engagement with each other during the winding process. At the terminal end of one cycle of winding operation, these gears are released from positive connection with a film winding mechanism, while the front and rear curtains are held in their cocked positions by separate latches in at least a time interval between a moment at which the diaphragm starts to move and a moment at which the mirror flips out of way to actuate release of the front curtain, thereby an electromagnetic release control for the rear curtain latch is prevented from being disturbed as by a shock which would be otherwise exerted on the rear curtain latch at the start of movement of the front curtain.

摘要： In a focal plane shutter having two curtains which unwind from shafts after being released, the shaft controls a master gear, causing a keying pin on the latter to activate braking action on the curtain at a time interval near the terminal end of running-down movement of the curtain, as a pair of heavy expanding frictional shoes are driven to rotate at accelerated speeds and pressed against the internal surface of a fixed drum by a centrifugal force. During the shutter cocking operation, the key is taken out of connection with the brake so that the driving torque of the film winding shaft is correspondingly decreased.

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： A motor drive unit adapted for use with a camera having a motorized shutter speed adjusting device. When a continuous series of frame exposures are to be made at a predetermined frame frequency, the set value of shutter time in the camera is made to be compared with the longest possible shutter time dependent upon that frame frequency by a comparator provided in the motor drive unit. When the actual shutter time value exceeds the longest possible one, the motorized shutter speed adjusting device is actuated, causing the shutter time value to change itself to the longest possible value.

摘要： An automatic exposure control apparatus of electric type for a photographic camera having an exposure control parameter setting means cooperative with a geometrical progression scale in isometric graduation is provided with a resistor device. The device includes a variable resistor having a grounded slider associated with the setting means upon movement thereof for providing a resistor value proportional to the amount of movement of the setting means, but to the reciprocal logarithm of the preselected parameter value. In order to minimize the complexity of a computer circuit responsive to the various outputs of the resistor device for performing photographic Appex computation, a bias voltage is applied to each of the variable resistors in a manner to produce a signal in the form of current proportional to the reciprocal of the amount of movement of the setting means. The resistor device has a single substrate having a plurality of resistor elements formed thereon by a metal coating technique and arranged for cooperation with respective sliders, thereby improving the exposure control accuracy and stabilization of the performance of the computer circuit against variation of temperature distribution in the apparatus.
