Lens barrel and imaging device

Abstract

The lens barrel includes a flexible wire, a first supporting frame and a second supporting frame. The flexible wire has a first end with at least one terminal, a second end with at least one terminal and a bent portion disposed between the first and second ends. The bent portion includes a plurality of part overlapping each other. The first supporting frame supports the first end. The second supporting frame is movably disposed in a first direction with respect to the first supporting frame and supports the bent portion.

1 . A lens barrel comprising:
 a flexible wire including a first end with at least one terminal, a second end with at least one terminal and a bent portion disposed between the first and second ends, the bent portion including a plurality of parts overlapping each other;   a first supporting frame configured to support the first end; and   a second supporting frame configured to support the bent portion, the second supporting frame being movably disposed in a first direction with respect to the first supporting frame and includes a first support portion and a second support portion facing the first support portion, the bent portion being disposed between and pressed against the first and second support portions via the resiliency of the bent portion caused by bending the bent portion.   
     
     
         2 . The lens barrel according to  claim 1 , wherein
 the second support portion is disposed in a second direction perpendicular to the first direction and facing the first support portion.   
     
     
         3 . The lens barrel according to  claim 1 , wherein
 the second support portion is disposed on the outer peripheral side of the first support portion and forms the outer peripheral part of the second supporting frame.   
     
     
         4 . The lens barrel according to  claim 1 , wherein
 the second supporting frame has a first limiter arranged to come in contact with the bent portion in the first direction.   
     
     
         5 . The lens barrel according to  claim 4 , wherein
 the first limiter connects the first support portion to the second support portion.   
     
     
         6 . The lens barrel according to  claim 5 , wherein
 the first support portion and the second support portion extend from the first limiter in the first direction.   
     
     
         7 . The lens barrel according to  claim 1 , wherein
 the flexible wire further includes a second intermediate portion disposed between the bent portion and the second end, and the second supporting frame further includes a second limiter arranged to come in contact with the second intermediate portion in the first direction.   
     
     
         8 . The lens barrel according to  claim 1 , wherein
 an end of the second support portion has a cut-out in the first direction.   
     
     
         9 . The lens barrel according to  claim 8 , wherein
 the flexible wire further includes a band-shaped first intermediate portion disposed between the bent portion and the first end, and the position of the cut-out corresponds to the first intermediate portion.   
     
     
         10 . The lens barrel according to  claim 9 , wherein
 the cut-out is wider than the first intermediate portion.   
     
     
         11 . The lens barrel according to  claim 9 , wherein
 the second support portion has a position display part that indicates a reference position for the first intermediate portion along the width direction of the first intermediate portion.   
     
     
         12 . The lens barrel according to  claim 1 , wherein
 the length of the second support portion is smaller in the first direction than the first support portion.   
     
     
         13 . The lens barrel according to  claim 1 , wherein
 the first support portion has a first support face parallel to the first direction and the second support portion has a second support face parallel to the first direction, and the bent portion is disposed between the first support face and the second support face.   
     
     
         14 . The lens barrel according to  claim 13 , wherein
 the first support face is a plane parallel to the first direction, and the second support face is a plane parallel to the first direction.   
     
     
         15 . The lens barrel according to  claim 1 , wherein
 the second supporting frame supports the second end of the flexible wire.   
     
     
         16 . An imaging device comprising the lens barrel according to  claim 1 . 
     
     
         17 . The lens barrel according to  claim 1 , wherein
 the flexible wire further includes a plurality of printed wires.
