摘要： A projection type image display apparatus includes an optical engine that emits a light according to image signal, a Fresnel lens on which the light emitted by the optical engine is incident and emitting the light as a parallel light, and a diffusion member that diffuses the parallel light emitted by the Fresnel lens. The projection type image display apparatus further includes a driving unit that moves the Fresnel lens or the diffusion member in a plane parallel to an emitting surface of the Fresnel lens or the diffusion member, a frame the supports the Fresnel lens, the diffusion member and the driving unit, a resilient supporting body that supports a weight of the Fresnel lens or the diffusion member with respect to the frame, and a holding unit that holds the Fresnel lens or the diffusion member so as to be movable in the plane parallel to the emitting surface of the Fresnel lens or the diffusion member.

摘要： A projection image display apparatus is provided which is capable of preventing misregistration in an on-screen image. A main frame assembly holds together an optical engine that modulates light emitted from a light source and a screen on which light emitted from the optical engine is projected, and the main frame assembly is configured to be supported by a bottom frame formed by a separate structure, whereby distortion having occurred at the bottom frame is caused not to transmit to the main frame assembly.
摘要翻译：提供了能够防止屏幕上图像不对准的投影图像显示装置。主框架组件将调制从光源发出的光和从光学引擎发射的光投射的屏幕的光学引擎固定在一起，并且主框架组件被构造成由由单独的结构形成的底部框架支撑使得在底部框架处发生的变形不会传递到主框架组件。

摘要： In a projection-type image display device, a driven member of a screen is displaced in a plane parallel to the screen. The driven member can be a Fresnel lens or a diffusing member. An elastic retaining unit holds the driven member in such a manner as to be capable of moving in the plane parallel to the screen, and a pair of driving sources applies driving forces in mutually intersecting directions to the driven member. A control circuit drives the pair of driving sources with driving waveforms having a prescribed phase difference therebetween so that the driven member makes continuous motion in a plane parallel to the screen when an image is projected.
摘要翻译：在投影型图像显示装置中，屏幕的从动构件在与屏幕平行的平面中移位。从动构件可以是菲涅尔透镜或漫射构件。弹性保持单元以与平行于屏幕的平面能够移动的方式保持从动构件，并且一对驱动源将相互交叉的方向的驱动力施加到被驱动构件。控制电路利用其中具有规定相位差的驱动波形来驱动该对驱动源，使得被驱动构件在投影图像时在与屏幕平行的平面中连续运动。
