    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 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.
