An image display apparatus includes: a transparent board that transmits visible light; a screen that is provided on one surface of the transparent board; a projector that projects an image toward the screen from the other surface side of the transparent board; and a support unit that supports the transparent board from the other surface side. The projector is disposed outside of the space that is enclosed by the transparent board and the support unit.

Image display apparatus and image display method

The present invention provides a sliding lens cover mechanism for a projector, which enables enhancement in operability and prevention of noise, and the sliding lens cover mechanism includes: a front panel that allows the projection lens to be exposed from a part thereof; a lens cover that moves over said front panel, from fully-open state in which the projection lens is exposed and a fully-closed state in which said lens cover covers the projection lens; and a slide device unit that biases the lens cover to move to a fully-open state or to a fully-closed state or to an intermediate state, wherein the lens cover includes a pin that protrudes toward the front panel; and wherein the front panel includes a slide plate that abuts against the pin only in the fully open state or in the fully closed state.

A rotary operation mechanism is provided with: a gear that is rotatably provided in the apparatus main unit of an electronic apparatus that is provided with an apparatus main unit and an outer case that covers this apparatus main unit; a rotating knob for effecting the rotary operation of this gear; and an opening that is provided in the outer case and into which the rotating knob is inserted. The rotating knob is supported in the outer case in a state of engagement that allows free rotation inside the opening. The rotating knob is provided with a first rib at a position that is separated in the radial direction from the center of rotation, and the gear is provided with a second rib that forms a gap in which the first rib is interposed and that thus makes line contact with and engages with the first rib.
