An imaging device includes an image sensor on which an object image is
formed via a photographing optical system; a radially-retracting device
which moves the image sensor between a photographing position, at which
the image sensor is located on a common optical axis of the photographing
optical system, and a radially-retracted position; and a flexible PWB for
electrically connecting the image sensor to an image processing circuit.
The flexible PWB includes a fixed portion positioned in front of the
retracted position of the image sensor, and a free-deformable portion
extending from the image sensor toward the fixed portion. The
free-deformable portion forms a shape to accommodate and cover the image
sensor when the image sensor is radially retracted to the
radially-retracted position, and is extended to form a shape to uncover
the image sensor when the image sensor is positioned in the photographing
position.
