Shutter cocking and release means for photographic apparatus with expansible housing

摘要

A still camera wherein the main section of the housing contains a shutter, a pivotable shutter cocking member, a normally open switch which must be closed to terminate an exposure, and a release for opening the shutter and for closing the switch. A second section of the housing is reciprocable with respect to the main section between an extended position in which the camera is ready to make an exposure and a depressed position in which the second section conceals the picture taking lens and the view finder in the main section. When the second section is moved to its depressed position, it directly or indirectly prevents the movement of release from a starting position and/or from closing of the switch. The shutter is cocked and the film is transported by the length of a frame in response to movement of the second section to its depressed position. A first spring biases the second section to its extended position and a second spring tends to close the switch but is prevented from establishing an electrical connection between two fixed contacts of the switch as long as the second section remains in the depressed position.
