Abstract
In the transmission of mechanical movements, a mechanical angular positioning device is provided, and applies to optical instruments to position an element like a mirror according to three predefined positions. The angular positioning device comprises a frame and two imbricated mechanical movement transmission assemblies. The first assembly comprises a first support in pivot connection with the frame according to a first axis, which is rotatable by a first motor via two connecting rods which generate two dead centers for the first support. The second mechanical assembly comprises a second support in pivot connection with the first support, according to a second axis, not parallel with first axis. This second support is rotatable by a second motor via two connecting rods which generate two dead centers for the second support. One of the dead centers of the first support can coincide with one of the dead centers of the second support.
