摘要： 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.

摘要： Disclosed is a light source device including a light source that includes a light emitting tube; and a cooler configured to cool the light emitting tube. The cooler includes an inlet port for drawing cooling air for cooling the light emitting tube; a flow channel that extends from the inlet port to the light emitting tube in a horizontal direction and that is for flowing the cooling air toward the light emitting tube; and a baffle plate that is disposed in the flow channel and that can slide in a gravity direction. The baffle plate has a shape and openings such that, in an installation state, an upper portion of the flow channel is opened and a lower portion of the flow channel is closed by the shape and positions of the openings of the baffle plate.
