    摘要： A camera having an automatic diaphragm control range where the exposure value derived from an exposure control circuit is introduced to a diaphragm mechanism through a scanning mechanism. The termination of scanning operation is electromagnetically effected by an arresting device comprising an electromagnet, an arresting lever carrying an armature, a first spring connected to the arresting lever to urge the armature for movement toward the electromagnet, a driving lever pivotal about a common shaft of the arresting lever and arranged to cooperate with a cocking and release member, a second spring connected to the driving lever and having a stronger force than the first spring by a magnitude necessary to permit the arresting operation of the arresting lever against the first spring, and a transmitting pin mounted on the arresting lever and extending into the range of movement of the driving lever at a point where the driving lever in the cocked position is spaced apart from the pin by a distance large enough to insure that the armature is brought into intimate contact with the electromagnet yoke under the same conditions each time the scanning mechanism is reset as the camera is cocked. The transmitting pin also serves as a position-adjusting means in order to insure that the time interval between the deenergization of the electromagnet and the initiation of arresting operation of the arresting lever by the driving lever is minimized and made uniform from camera to camera to improve the accuracy of diaphragm control.

    摘要： A photographic camera having a magnetic actuating device associated with an electronic control device for initiating a release of one or more of the camera mechanisms from the cocked position thereof. In one embodiment of the invention, the magnetic actuating device comprises a single magnetic winding with a core material having a substantially rectangular hysteresis loop, and an armature of which the movement is controlled by the polarity of the magnetic winding and which is connected to spring-biased means for latching the mechanism in the cocked position. After the core is magnetized by applying a voltage to the magnetic winding for a relatively short period to hold the armature with the latching means in the cocked position against the force of the spring, the magnetic winding is energized by an output of the opposite polarity from the electronic control device causing the armature to move away from the core, whereby the release of the mechanism is initiated.

    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 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.
