Variable Character Keyboard

Variable-character keyboards permit use of a single set of key buttons for two or more sets of completely different characters. One method of achieving such a keyboard is to use key buttons with transparent tops. The character is inside the button and is clearly viewed from the top.

In simplest form the character mey be displayed on a flip pable disk. On one side is the character X, for example, and on the reverse side is the character Y. If the disk contains a permanent magnet that can orient or flip the disk, depending on the application of an external magnetic field, the X or Y character may be displayed. In this simple form a two character per button keyboard is made.

A more complex multicharacter display is possible using a polyhedron, with each face of the polyhedron containing a given character. External flipping means permits variation of the character.
