A retracting mechanism for a lens barrel, the mechanism includes a non-rotatable
member having an engagement surface; a frame movable along an axis towards and
away from the non-rotatable member without rotation and having a holder for holding
an imaging element, the holder pivotally mounted to the frame for movement between
an aligned position where the lens barrel component is aligned with the axis and
a displaced position where the component is displaced relative to the aligned position;
and a spring assembly configured to resiliently hold the holder at the aligned
position and having an engagement surface configured to contact the engagement
surface of the non-rotatable member during movement of the frame towards the non-rotatable
member, overcome the resilient holding of the holder at the aligned position, and
move the holder from the aligned position to the displaced position.
