Electronic apparatus with a flat panel keyboard unit

A flat panel keyboard comprising:

• a flexible user-actuable surface plate having a plurality of key symbols adhered to the surface thereof which are visible to a user;
• a flexible base with a connecting wiring pattern and key electrode pattern on the rear surface thereof, said key electrode pattern being a pair of electrodes in alignment with said plurality of key symbols;
• a flexible cabinet member having a plurality of integral recessed portions in alignment with said key electrode pattern;
• and
• a plurality of pressure sensitive conductive means positioned in said plurality of recessed portions, wherein said plurality of key electrode patterns are in continuous surface contact with said plurality of pressure sensitive conductive means so that upon actuation of one of said plurality of key symbols on said flexible user-actuable surface plate, a corresponding electrode pattern is forced against a respective pressure sensitive conductive means, shorting said electrode pattern and generating a signal;
• said surface plate, said flexible base, and said flexible cabinet member being adhered together in a flat compact relationship, said flexible base includes a plurality of slits formed therein on either side of each of said pair of electrodes to facilitate an up-down actuation of said flexible base.
