Flash mechanism for camera

Claim 1

A flash mechanism for a camera of the type comprising: diaphragm and shutter means for opening and closing a light imaging path in said camera; and pin means for driving said diaphragm and shutter means and movable along a predetermined path whose length is proportional to the amount of the opening of said light imaging path; said mechanism comprising: diaphragm linkage lever means for entering said path of movement of said driving pin means when an illumination device is attached to said camera, and for retracting from the path of movement of said pin means when the illumination device is detached; an intermediate linkage lever means for respectively moving in response to the attachment and detachment of said illumination device and cooperatively linked to said diaphragm linkage lever means for accordingly operating said diaphragm linkage lever means in response to said respective movements; rotatable distance ring means for adjusting the focussing of said camera and having a distance cam means thereon for engaging said intermediate linkage lever means to limit the extent of its respective movement in response to the attachment of the illumination device; and rotatable exposure correction means for setting the exposure of said camera and which supports and is relatively rotatable to said distance ring means; and wherein the center of rotation of said distance ring means on said exposure correction means is slightly displaced from the rotation center of said exposure correction means such that the position of said distance cam means is laterally displaced upon rotation of said exposure correction means.
