Abstract
Abstract A space is formed between a wall of a camera body and a part of a printed circuit board fixed to the wall of the camera body. A part of a flexible printed circuit and a resilient member are inserted into the space to resiliently press the flexible circuit onto the printed circuit board to assure a tight electric contact between the flexible printed circuit and the printed circuit board.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
176 words
A printed circuit for a photographic camera mounted to a wall of a camera body comprising in combination: a printed circuit board composed of an insulating substrate and a conductive layer provided thereon, said printed circuit board being mounted to a part of the wall of a camera body of the camera with the conductive layer thereof facing the wall, said wall of the camera body having a recessed portion to form a space between the same and said printed circuit board mounted thereto, a flexible printed circuit member having a conductive layer a part of which is exposed, said flexible printed circuit member being inserted into said space with the exposed conductive part thereof put into contact with said conductive layer of the printed circuit board, and a resilient member inserted into said space between the flexible printed circuit member and the recessed portion of the wall of the camera body to put the exposed conductive layer of the flexible printed circuit member into pressure contact with the conductive layer of the printed circuit board.
Claim 2
Dependent Claim
176 words
A printed circuit for a photographic camera mounted to a wall of a camera body comprising in combination: a printed circuit board composed of an insulating substrate and a conductive layer provided thereon, said printed circuit board being mounted to a part of the wall of a camera body of the camera with the conductive layer thereof facing the wall, said wall of the camera body having a recessed portion to form a space between the same and said printed circuit board mounted thereto, a flexible printed circuit member having a conductive layer a part of which is exposed, said flexible printed circuit member being inserted into said space with the exposed conductive part thereof put into contact with said conductive layer of the printed circuit board, and a resilient member inserted into said space between the flexible printed circuit member and the recessed portion of the wall of the camera body to put the exposed conductive layer of the flexible printed circuit member into pressure contact with the conductive layer of the printed circuit board.
Claim 3
Dependent Claim
30 words
A printed circuit for a photographic camera as claimed in claim 1 wherein said flexible printed circuit member comprises a conductive layer sandwiched between a pair of insulating cover layers.
