Latest Patents
Toyama's latest patents include a lens driving device, an autofocus camera, and a camera-equipped mobile terminal. These innovations are designed to correct the movement of a lens in the optical axis direction and to reduce the dimensions of the device in the optical axis direction. The lens driving device features a lens support that holds the lens at its inner circumference, along with multiple coils arranged at regular intervals around the lens support. A base supports the lens support, allowing it to move freely in the optical axis direction. The device utilizes a magnet portion that interacts with the coils, applying equal electric current to each coil when moving the lens support. Additionally, the current values can be varied to correct any tilt in the optical axis of the lens.
Another patent focuses on a lens driving device that incorporates a spring mechanism. This device includes an outer ring portion fixed to a body, an inner ring portion fixed to a lens support, and an arm portion connecting the two. The lens support is moved in the optical axis direction through electromagnetic force generated by electric current applied to a coil from a terminal member. This innovative design enhances the functionality and efficiency of camera systems.
