摘要： An imaging device includes an axial-direction moving member which moves between an operating position and a retracted position in an optical axis direction, an in-plane moving optical element movable in a plane orthogonal to the optical axis, a controller which moves the in-plane moving optical element in the orthogonal plane to a reference position when the image device changes from the operating state to the retracted state, and a mechanical guide device, provided between the axial-direction moving member and the in-plane moving optical element. In a state where the in-plane moving optical element is deviated from the reference position, the mechanical guide device guides the in-plane moving optical element to the reference position by using a moving force of the axial-direction moving member when the axial-direction moving member moves from the operating position to the retracted position.

摘要： A shift mechanism includes first and second ring bodies which are relatively rotatable; a shift cam surface formed on the first ring body on an end surface thereof which faces the second ring body, the shift cam surface being inclined with respect to a circumferential direction of the first ring body; a follower projection formed on the second ring body for engaging with the shift cam surface; and a rotating mechanism for relatively rotating the first and second ring bodies. The shift cam surface and the follower projection are arranged to move the first and second ring bodies toward and away from each other in the axial direction as the first and second ring bodies are relatively rotated. An annular rib is formed along the circumference of the first ring body outside the shift cam surface over the follower projection of the second ring body.
