Abstract
A lens barrel (10) comprises a holding frame (51); a guide pole (53); a focusing lens unit (52) that is slidably guided by the guide pole (53) and moves in an axial direction; an actuator that moves the focusing lens unit (52) in the axial direction relative to the holding frame (51); and leaf springs (55) that support the guide pole (53) so as to allow movement in the axial direction relative to the holding frame (51), at an amplitude smaller than the stroke of the focusing lens unit (52).
Claims12
A lens barrel, comprising:
- a support frame;
- a shaft;
- a movable frame configured to be slidably guided by the shaft and moves in an axial direction;
- an actuator configured to move the movable frame relative to the support frame in the axial direction;
- and
- support portions configured to support the shaft passively along with the movement of the movable frame and to permit movement of the shaft with respect to the support frame in the axial direction at a non-zero amplitude of about 1 mm or less.
