Latest Patents

Hara's latest patents include a "Light Amount Adjusting Apparatus and Projector Using the Same." This invention features at least a pair of light amount adjusting plates that are strategically placed at the peripheral side rim portions of a light path. These plates can be driven between a narrow-down position, where they enter the light path, and a retreat position, where they move outside the light path. A restriction member, such as a stopper, limits the rotation of the light amount adjusting plate at the retreat position, while a holding unit maintains the plate's position.

Another significant patent is the "Light Quantity Adjusting Device and Projector Apparatus Using the Same." This device is designed to adjust the light quantity of a projector. It includes a substrate with an optical path opening and a blade guide surface featuring level differences. A series of blade members are arranged around the optical path opening, allowing them to rotate and open or close the optical path. A transmission member engages the blade members, and a drive device facilitates their movement.
