Abstract
Abstract A device for electrically connecting first and second members movable relative to each other, includes a flexible printed circuit board located between the first and second relatively movable members. The flexible printed circuit board has a first side piece and second side piece divided by a cutout made in the flexible printed circuit board. One of the first and second side pieces is bent about 180° in the direction of the relative movement of the first and second members to form a turned "U" shaped portion. The first side piece has its free end portion fixed to the first member and the second side piece has its free end portion fixed to the second member, so that the displacement of the printed circuit board resulting from the relative movement of the first and second members is absorbed by movement of the "U" shaped portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A device for electrically connecting first and second members movable relative to each other, comprising a flexible printed circuit board located between said first and second relatively movable members, said flexible printed circuit board having a first side piece and a second side piece divided by a cutout made in said flexible printed circuit board, one of said first and second side pieces being bent about 180° in the direction of the relative movement of the first and second members to form a turned "U" shaped portion, said first side piece having its free end portion fixed to said first member and said second side piece having its free end portion fixed to said second member, so as to absorb displacement of said printed circuit board resulting from the relative movement of said first and second members by movement of said "U" shaped portion.
Claim 2
Independent Claim
144 words
A device for electrically connecting first and second members movable relative to each other, comprising a flexible printed circuit board located between said first and second relatively movable members, said flexible printed circuit board having a first side piece and a second side piece divided by a cutout made in said flexible printed circuit board, one of said first and second side pieces being bent about 180° in the direction of the relative movement of the first and second members to form a turned "U" shaped portion, said first side piece having its free end portion fixed to said first member and said second side piece having its free end portion fixed to said second member, so as to absorb displacement of said printed circuit board resulting from the relative movement of said first and second members by movement of said "U" shaped portion.
Claim 3
Dependent Claim
28 words
A device according to claim 1, wherein said first and said second members are in such relation that one of them is fixed, and the other is movable.
Claim 4
Dependent Claim
25 words
A device according to claim 2, wherein said movable member fixedly carries an actuator connected to the free end portion of said printed circuit board.
Claim 5
Dependent Claim
18 words
A device according to claim 3, wherein said first and said second members both are of cylindrical form.
Claim 6
Dependent Claim
28 words
A device according to claim 1, wherein said printed circuit board is formed to a stripe like shape extending to the direction of relative movement of said members.
Claim 7
Independent Claim
131 words
A device for electrically connecting a first member of cylindrical inside shape and second member movably inserted into said first member, both member being relatively movable, comprising a flexible printed circuit board located between said first and second members, said printed circuit board being of band form extending in the direction of the relative movement of said first and second members and being bent about 180° to form a turned "U" shaped portion, lying in a space defined by said first and second members, said "U" shaped portion having an area wider in the direction of the circumferential direction of said cylindrical inner surface of said first member than other areas, along said wider area said "U" shaped portion displacing due to the relative movement of said first and second members.
Claim 8
Independent Claim
131 words
A device for electrically connecting a first member of cylindrical inside shape and second member movably inserted into said first member, both member being relatively movable, comprising a flexible printed circuit board located between said first and second members, said printed circuit board being of band form extending in the direction of the relative movement of said first and second members and being bent about 180° to form a turned "U" shaped portion, lying in a space defined by said first and second members, said "U" shaped portion having an area wider in the direction of the circumferential direction of said cylindrical inner surface of said first member than other areas, along said wider area said "U" shaped portion displacing due to the relative movement of said first and second members.
Claim 9
Dependent Claim
28 words
A device according to claim 6, wherein said first and said second members are in such relation that one of them is fixed, and the other is movable.
Claim 10
Dependent Claim
25 words
A device according to claim 7, wherein said movable member fixedly carries an actuator connected to the free end portion of said printed circuit board.
Claim 11
Dependent Claim
32 words
A device according to claim 6, wherein said wider area of said printed circuit board has its wiring pattern formed only in the same lateral area as that of said other areas.
