Abstract

This electromagnetic actuator has a plurality of discrete positions. A pair of actuating arms 10 and 11 are pivotally connected by means of flexible wires 17 and 18 to matrix holder 12 at points 13 and 14. Each arm is moved by energizing the appropriate combination of the six associated solenoids 19A, 19B, 19C and 20A, 20B, 20C. Since arms 10 and 11 pivot about the point of attachment to the solenoids, each combination of energized and de-energized solenoids positions the end of the arm differently.

Matrix Positioning

This electromagnetic actuator has a plurality of discrete positions. A pair of actuating arms 10 and 11 are pivotally connected by means of flexible wires 17 and 18 to matrix holder 12 at points 13 and 14. Each arm is moved by energizing the appropriate combination of the six associated solenoids 19A, 19B, 19C and 20A, 20B, 20C. Since arms 10 and 11 pivot about the point of attachment to the solenoids, each combination of energized and de-energized solenoids positions the end of the arm differently.

Movement of arm 11, moved by solenoids 20A, 20B, 20C, causes holder 12 to rotate about pivot 13 and select one of rows 15. Movement of arm 10, moved by solenoids 19A, 19B, 19C, rotates matrix holder 12 about pivot 14 to select one of columns 16. By positioning the holder to the appropriate column and row, any desired character of matrix 21 is moved in front of an aperture for projection on a screen by a lens system (not shown).
