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 rotary drive. Notably, the driven shafts of these rotary drives are not aligned parallel to the sliding direction, and the polarization directions of the magnets are oriented at right angles to their respective shafts.
In an alternative embodiment, the device can include two shutter blades, each with its own sliding body, allowing for a more complex operation. The design maintains the same principles of magnetic guidance and movement, with the linear guides and rotatable magnets arranged similarly to the first embodiment. The patent also specifies that the driven shafts for both shutter blades are aligned at right angles to their respective sliding directions. Additionally, the sliding bodies of the shutter blades can be mirror images of each other, enhancing the device's symmetry and functionality. The inclusion of magnet holders with slots for rotation stops further ensures precise control over the movement of the magnets, contributing to the overall efficiency and reliability of the camera shutter device.
