ABSTRACT:
A shutter release device for an autofocusing camera has a release member movable by manual operation from an initial position to a first position, and from the first position to a second position. A first release device connected to the release member releases a focus adjustment mechanism upon movement of the release member to the first position. The focus adjustment mechanism has a first lock device for holding a shutter operating mechanism in a first locked condition, and releases the shutter operating mechanism upon release of the focus adjustment mechanism. A second lock device, controlled by an electromagnet, holds the shutter operating mechanism in a second locked condition, and a second release device actuated by movement of the release member to the second position causes the electromagnet to release the second lock device and thereupon the shutter operating mechanism. Thus, a simple shutter release device is provided for the autofocusing and shutter operating functions using a single control electromagnet.
