ABSTRACT:
Electromechanical apparatus for setting up and erasing alpha-numeric characters or other symbols in braille by means of a tactile display. Dot pins simulating braille are supported for movement within holes in a display plate to a position protruding therefrom to form tactile characters and for retraction to a withdrawn position flush with the surface of the display plate. Solenoid-operated plungers are arranged to selectively project the dot pins. Latch elements are movable by energization of the solenoid to a position to support the plungers in their operative position, a common support for the latch elements movable in a plane perpendicular to the axis of the support plungers to remove the latch elements and spring means for restoring the support plate to its initial position.
