<p><P>PROBLEM TO BE SOLVED: To provide a key input circuit unit for an electromagnetic cooker for obtaining a membrane key wherein a key input condition can be in the same degree even if using any key, by routing wiring within the limit of the membrane key. <P>SOLUTION: In a key operation input means 1, a plurality of setting keys assigned to functions of the electromagnetic cooker and arranged in lines as the membrane keys are constituted in a redundant matrix. A relay substrate 2 is changed in the number of poles by being reduced from the number of poles of the input-side port connected with each port of the matrix of the key operation input means 1 to the number of poles of an output side port of the number corresponding to the setting keys and connected with a microcomputer controlling the electromagnetic cooker. Since the membrane key constituting the key operation input means 1 can uniformly route the resistance of the internal wiring for the setting keys of the same contents on right and left sides, the pushing conditions of the keys can be made the same. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
