Abstract
Abstract An electric connector for camera is adapted to form an electric connection between an electric device within a taking lens barrel and an electric device within a finder system of the camera. The connector is disposed between the mount for mounting the lens barrel and the holder for mounting the finder system. The connector comprises first and second contacts. The first contact is connectable to the electric device in the lens barrel when the latter is mounted. The second contact is in electric connection with the first contact and connectable to the electric device in the finder system when the latter is mounted.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
208 words
In a camera having a housing and a mount disposed on a front portion of the housing for receiving a lens barrel and a holder disposed on an upper portion of the housing for supporting a finder system, both the lens barrel and the finder system being exchangeable and each having a built-in electric device, the improvement comprising: means for electrically connecting the electric device in said lens barrel and the electric device in said finder system; said electric connection means being disposed between said mount and said holder and having first and second contacts; said first contact being connectable to the electric device in said lens barrel when the latter is mounted on said mount; said second contact being in connection with said first contact and connectable to the electric device in said finder system when the latter is mounted on said holder; and said electric connection means further including a frame member which is arranged to pass through said camera housing from said front portion to said upper portion, said first contact being exposed from one surface of said frame member, said second contact being exposed from another surface of said frame member, and means for electrically connecting directly said first contact and said second contact.
