摘要： In the disclosed camera and power winder arrangement, a power winder winds the film and contains a rewinder. A detector responds to rewinding movement of the film past a predetermined position, and a control circuit responds to the detector's sensing that the film has stopped moving past the predetermined position by braking the film rewind source.

摘要： In the disclosed camera system, a spring arrangement to drive an automatic exposure mechanism of a camera and a magnet arrangement to control starting and stopping of the AE mechanism of the camera are provided within an electric drive device, and the automatic exposure control of the camera is carried out by mounting the electric drive device on the camera. Facilities, when energized by a power supply, are set to supply driving power to a motor for cocking the shutter, and an arrangement supplies power from the power source to the magnet arrangement for actuating the magnet arrangement. The present invention eliminates disadvantages of prior camera systems, namely, inferior response characteristic of the magnet and erroneous operations by the release action, and a large number of connecting terminals.

摘要： A storage device for storing photographic exposure information employs a closed-loop analog-to-digital (A-D) converter circuit includes a counter and a digital-to-analog (D-A) converter. The influence of erroneous signals which are created at the output of the D-A converter when the exposure information is stored in the counter is eliminated. The D-A converter circuit employs a ladder network of coarse accuracy. The stored exposure value, however, is highly accurate because of the closed-loop nature of the A-D converter circuit. Means responsive to the stored value for operating the exposure system of the camera are disclosed.
