Abstract:
An image generation device includes an image generator, a stationary unit, a movable unit, a driver, and a wiring board. The image generator receives light and generate an image. The movable unit includes a movable plate movably supported by the stationary plate of the stationary unit, the image generator mounted on the movable plate, and a diffusion heat radiator connected to the movable plate, to cool the image generator. The driver relatively moves the movable unit with respect to the stationary unit. The driver includes a driving coil disposed in the radiator and a driving magnet opposed to the coil. The wiring board is connected to the movable unit, to pass a current through at least the coil. A movable area of the wiring board in which the wiring board moves with movement of the movable unit does not overlap any of the coil and the magnet in plan view.
