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 cam mechanism includes a cam ring having front and rear cam grooves which have a common reference cam diagram and are formed so that a front part of the front cam groove and a rear part of the rear cam groove are omitted from the reference cam diagram. A normal-width section and a wide-width section are provided in each of the front and rear cam grooves. In a zoom range, an associated cam follower of a driven member is engaged in the normal-width section of one of the front and rear cam grooves, and another associated cam follower of the driven member is positioned out of the other of the front and rear cam grooves. In a transition state between the zoom range and an accommodated position, both of the associated cam followers are positioned out of the normal-width sections of the respective front and rear cam grooves.

摘要： An imaging device includes a rectangular image sensor, and an imaging optical system which includes an on-axis lens element and a radially-retractable lens element. The radially-retractable lens element is supported by a free end of a swingable arm pivoted about an axis eccentric from the imaging optical axis. The on-axis lens element is non-circular, defined by a removed portion from a reference circle thereof along a long side of the image sensor. When in the off-axis displaced position, the radially-retractable lens element utilizes the removed portion of the on-axis lens element and the radially-retractable lens element is offset from a plane through the imaging optical axis and parallel to the short sides of the rectangular imaging surface. The swing axis is on the on-axis lens element side, in the long side direction, closer to the optical axis of the radially-retractable lens element in the off-axis displaced position.

摘要： A light shielding structure of an optical device includes outer and inner annular members which move relative to each other in an axial direction, small and large diameter outer peripheral portions formed on the inner annular member, and a light shielding ring positioned inside the outer annular member and supported thereby. The light shielding ring does not contact the small-diameter outer peripheral portion of the inner annular member. The light shielding ring and the large-diameter outer peripheral portion of the inner annular member coincide with each other in the axial direction in an operating state of the optical device whereby a clearance between the outer annular member and the inner annular member is made light-tight. The light shielding ring and the small-diameter outer peripheral portion of the inner annular member coincide with each other in the axial direction in a non-operating state of the optical device.
