An image projection apparatus includes: an exhaust fan configured to discharge air in the apparatus to outside of the apparatus; a light source; and a plurality of ducts each having an air intake port facing the light source, and arranged side by side in a rotation axis direction of the exhaust fan. A duct closer to the exhaust fan in a rotation axis direction of the exhaust fan, has a larger flow path sectional area and has an outflow port from which air flows out, placed closer to the light source, in a direction perpendicular to the rotation axis direction of the exhaust fan.

An image projection apparatus includes an image generator configured to use light emitted from a light source to generate an image; a movable member in which the image generator is disposed, the movable member being movably supported; a fixed member being fixed and configured to movably support the movable member; and a mover configured to move the movable member. The mover includes a first pair of actuators facing each other in a first direction across the image generator, and a second pair of actuators facing each other in the second direction across the image generator. The first pair of actuators causes a driving force to operate on the movable member in a direction parallel to a second direction orthogonal to the first direction. The second pair of actuators causes a driving force to operate on the movable member in a direction parallel to the first direction.

An image projection apparatus includes: a light source; an exhaust fan configured to discharge air in the apparatus to outside of the apparatus; and a plurality of wind guiding walls extending in a direction perpendicular to an exhaust direction of the exhaust fan, and configured to guide air that has cooled the light source. The wind guiding walls are arranged side by side in a rotation axis direction of the exhaust fan. At least a downstream portion of each of the wind guiding walls in an air flowing direction after cooling the light source, is gradually inclined so as to move away from the exhaust fan in the rotation axis direction of the exhaust fan, toward downstream in the air flowing direction.

An illumination optical system is provided that is configured to guide light emitted from a light source to an image generation unit that is arranged to be movable in a direction perpendicular to incoming light and is configured to generate an image by reflecting the incoming light. The illumination optical system includes a first lens that is arranged to be movable in a direction perpendicular to an optical axis of the first lens, a second lens that is arranged to be movable in a direction that changes a face-to-face distance between the first lens and the second lens, and a lens position control unit configured to displace the first lens and the second lens.

An image display unit includes a first unit fixed to a receiving frame, a second unit, movably supported by the first unit, including an image generator to generate an image when light enters the image generator, and a first link unit to supportingly fix the first unit to the receiving frame, and a space between the first unit and the receiving frame adjustable by the first link unit.
摘要:
An image generating unit includes an image generating part configured to generate an image from illumination light; a driving magnet configured to generate a magnetic field; a driving coil arranged in the magnetic field of the driving magnet; a heat radiating part coupled to the image generating part and configured to radiate heat of the image generating part. The driving magnet and the driving coil move the image generating part and the heat radiating part. The driving coil is placed at the heat radiating part via a substance, thermal conductivity of the substance being lower than thermal conductivity of the heat radiating part.
