Abstract

PURPOSE:To prevent an erroneous operation caused by static electricity or surge current in a heating cooker, to which a micro computer is built-in, by making a base panel of a cooker of nonconducting material, and by composing a keybord such that an electricity conducting part for earth is extended from a keyboard and static electricity charged to a keyboard is grounded to a chassis by the intermediary of a back plate. CONSTITUTION:A keyboard 7 is composed of a base-board 8, a spacer 11, an insulated sheet 13, an aluminum foil sheet 14, and a character sheet 15, all of which are laminate- bonded in layer, as well as a panel base 3 is made of nonconducting material. The extended part 18 of an aluminum foil sheet 14 from a keyboard 7 is fitted to a back plate 19 which is grounded to a chassis 22. With such an arrangement, the static electricity charged to a human body and the like is not conducted to a panel base through a keyboard 7, and the static electricity charged to a keyboard 7 is grounded through an aluminum foil sheet 14, a back plate 19, and a chassis 22. Accordingly, an erroneous signal is prevented from coming out of a micro computer 26, an electronic part 27, switches 9 and 10, and the like. As a result, an erroneous operation due ts static electricity or surge current can be prevented.
