    Abstract: An imaging device includes: imaging lens displaceable in first and second directions in plane perpendicular to optical axis; actuator positioning the imaging lens in the first and second directions; position detector generating first and second position detection signals Hx and Hy, Hx including crosstalk component caused by displacing the imaging lens in the second direction, and Hy including crosstalk component caused by displacing the imaging lens in the first direction; crosstalk compensator correcting Hx and Hy to reduce crosstalk components included in Hx and Hy; and driver controlling the actuator based on corrected first and second position detection signals Hx′ and Hy′, wherein when ratio of Hy to Hx while driving the imaging lens in the first direction is α and ratio of Hx to Hy while driving the imaging lens in the second direction is β, the crosstalk compensator reduces crosstalk components included in Hx and Hy.

    Abstract: A projector includes: an image light generating section generating image light; a projection lens projecting the image light emitted from the image light generating section; a lens shift mechanism moving the projection lens in a first direction orthogonal to an optical axis of the projection lens; an external housing accommodating the image light generating section and the lens shift mechanism and including an opening surrounding the projection lens; and a fitting mechanism attached to the external housing. The external housing includes a notch portion formed by cutting off a portion of the peripheral edge of the opening and located in the first direction with respect to the projection lens. The fitting mechanism includes a fitting portion fitted into the notch portion and forming a portion of the peripheral edge. The fitting portion moves away from the projection lens by being pressed from the projection lens side.

    Abstract: An X-axis movable object holding portion to hold an X-axis movable object to be movable in an X-axis direction is provided at a position facing an X-axis actuator with an optical axis between the X-axis movable object holding portion and the X-axis actuator in a base member. A Y-axis movable object holding portion to hold a Y-axis movable object to be movable in a Y-axis direction is provided at a position facing a Y-axis actuator with the optical axis between the Y-axis movable object holding portion and the Y-axis actuator in the X-axis movable object. An auxiliary member supports a carrier actuator to move a lens carrier. In the lens carrier, a movement of the direction of the optical axis is regulated by a carrier stopper mechanism.
