Camera shutter device with permanent magnets
摘要:
A camera shutter device having a shutter blade which moves abruptly between a first position, in which it covers a transmission zone present between the carriers, and a second position, in which it opens up the transmission zone. On the shutter blade, there is provided a slide body which includes a displaceable permanent magnet and which is guided on a linear guide, the ends of which are assigned a respective rotatable permanent magnet. By oppositely changing the polarization direction of the rotatable permanent magnets through 180°, the displaceable permanent magnet is pulled into the first or second position.
