A multifunctional microprocessor device includes a mainframe, a lower slide plate made to slide on the mainframe in the transverse direction and having a forked contact metal spring inserted through a first through hole on the mainframe and series of longitudinally aligned windows to show character codes around the keys on the mainframe, an upper slide plate made to slide on the mainframe in the longitudinal direction and having a forked contact metal spring inserted through a second through hole on the mainframe and series of transversely aligned windows to show character codes around the keys on the mainframe, wherein moving the upper and/or lower slide plates longitudinally or transversely causes the forked contact metal spring of either slide plate to contact either contact on the electronic circuit of the mainframe, and therefore the microprocessor unit is switched to the function modes corresponding to the character codes shown through the windows on the upper and lower slide plates.
