| 发明名称 | Lens barrel | ||
| 摘要 | Embodiments of a lens barrel may comprise an imaging optical system with a plurality of lenses, a cylindrical focusing manipulation component, a stationary frame, and a restrictor. The focusing manipulation component changes the focal position of the imaging optical system by turning operation around the optical axis of the imaging optical system and to set the distance up to a second imaging region that is at least partially different from a first imaging region, and to move at least some of the lenses of the imaging optical system to switch between first and second imaging states. The restrictor restricts the rotatable range of the focusing manipulation component. When the focusing manipulation component is turned, its rotatable range is switched from a first rotatable range to a second rotatable range. | ||

| 主权项 | 1. A lens barrel, comprising: an imaging optical system including a plurality of lenses; a cylindrical focusing manipulation component configured to change the focal position of the imaging optical system by turning operation around the optical axis of the imaging optical system and to set the distance up to a second imaging region that is at least partially different from a first imaging region, and to move at least some of the lenses of the imaging optical system to switch between first and second imaging states; a stationary frame configured to support the focusing manipulation component in a rotatable state; and a restrictor configured to restrict the rotatable range of the focusing manipulation component in the first imaging state and the second imaging state, wherein when the focusing manipulation component is turned to switch from the first imaging state to the second imaging state, the rotatable range of the focusing manipulation component restricted by the restrictor is switched from a first rotatable range corresponding to the first imaging state to a second rotatable range in which the position is shifted in the peripheral direction from that of the first rotatable range, corresponding to the second imaging state. | ||
