    • A roll film camera of the type in which the film may be contained either in a magazine of normal film frame capacity removably mounted within the camera body or in a magazine of large film frame capacity detachably mounted on the rear of the camera body and in which the film transport and shutter tensioning mechanisms are operatively connected with each other by means of a single operating member. The film transport mechanism is provided with clutch means arranged between said single operating member and the driving means for the camera side takeup spool upon attachment of the large capacity film magazine to the camera body for disconnecting the takeup spool driving means from the single operating member.

    • 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.
