Camera shutter device using magnetic forces for operation
The patent US12044958B2 describes a novel camera shutter device that utilizes magnetic forces for its operation. The device features a frame with two supports positioned opposite each other, along with a linear sliding structure that facilitates the movement of a shutter. This shutter is designed to alternate between two positions: one that covers a transmission zone and another that clears it. The shutter comprises a shutter blade and a sliding body, which is either a displaceable permanent magnet or contains one. This sliding body is guided along a linear guide that connects to two rotatable permanent magnets, each linked to a driven shaft of rotary drives that are not aligned parallel to the sliding direction. The polarization directions of these magnets are oriented at right angles to their respective driven shafts, enhancing the device's functionality.
In an alternative embodiment, the patent outlines a dual-blade shutter system, where each shutter blade is paired with its own sliding body, also utilizing displaceable permanent magnets. Similar to the single-blade design, the linear guides for both shutter blades are adjacent to rotatable permanent magnets connected to driven shafts, maintaining the same angular relationships. The design allows for precise control of the shutter's movement, with features such as magnet holders that include slots for rotation stops, ensuring stability and accuracy during operation. The innovative use of magnetic forces in this camera shutter device presents a significant advancement in shutter technology, potentially improving performance in various photographic applications.
