Abstract
A base member holds a first ring-shaped operating member such that the first ring-shaped operating member can move rectilinearly in a direction perpendicular to the optical axis of a lens unit and holds a second ring-shaped operating member such that the second ring-shaped operating member can rotate about the optical axis of the lens unit. When the rotation of the second ring-shaped operating member is not detected by a rotation detection unit, a restricting unit permits rectilinear movement of the first ring-shaped operating member, and when the rotation of the second ring-shaped operating member is detected by the rotation detection unit, the restricting unit restricts the rectilinear movement of the first ring-shaped operating member.
