A microwave oven includes a widely applicable and extensible Reduced Instruction
Set Computer (RISC) microprocessor, allowing a control panel to be easily included,
and which controls various functions using a single microprocessor, reducing a
size of the control panel. The microwave oven also includes a control panel in
which soft touch switches using electrostatic capacity are substituted for membrane
switches, allowing the control panel to be formed in various forms including a
curved form.
