摘要： There is provided a projection-type image display apparatus which is capable of solving the problem in which the reduction ratio of speckles is small. Light source emits a light beam that is modulated according to a video signal. Projector projects the light beam emitted from light source to display an image. Changer changes a polarized state of the light beam emitted from the light source to projector or changes a polarized state of the light beam projected by the projector. Controller repeatedly selects a plurality of predetermined particular polarized states according to a predetermined sequence. Controller switches the polarized state changed by the changer to the selected particular polarized states.

摘要： A drive unit includes a motor disposed in a motor case, a controller, disposed in a controller case, and a lever. The lever includes a supported portion that is fitted on a support of the controller case in a rotatable manner, a first action point at a first distance from the supported portion, and a second action point at a second distance from the supported portion. When the lever rotates from a close state toward an open state according to an application of a first force to the first action point, the second action point abuts on a specific part on the motor case, thereby generating a second force from the second action point to the specific part in a parallel direction of the axis of the motor case, with its reaction force reversely applied from the supported portion to the support as a third force.

摘要： An image display device may include a varifocal optical element that condenses a light beam emitted from a light source and scans a projection surface with the light beam from the varifocal optical element. The varifocal optical element may include lenses located side by side in a direction orthogonal to their optical axes that are in parallel with each other; an orthogonal plane mirror that reflects the beam that passes through one of the lens to the other lens; and an actuator that moves the orthogonal plane mirror in parallel along the optical axes of the lenses. The displacement of the actuator may be controlled based on the scanning angle.
