Latest Patents

Usami's latest patents include a lens driving apparatus and a method of manufacturing the lens driving apparatus. This innovative lens drive device features an objective lens and a lens holder, to which coils for drive control are attached. The side surface of the lens holder is designed with an irregular surface that includes a recess/projection section, which restricts the flow direction of adhesive. This design allows for the coils and lens holder to be integrally formed with the adhesive, enhancing the device's structural integrity.

Another significant patent is for an optical pick-up apparatus. This invention includes a stopper that has a projected portion to restrict the movement of a movable section in the focusing direction, as well as a wall section to limit movement in the tracking direction. Both components are integrally formed from synthetic resin, allowing a single stopper to manage both movements simultaneously. This innovation reduces the number of components required, lowers costs, and simplifies the mounting process. Additionally, the stopper is designed to withstand strong impacts without deformation.
