<p><P>PROBLEM TO BE SOLVED: To determine key depression at the same level at each of a plurality of touch keys. <P>SOLUTION: This induction heating cooker is equipped with an operation part 9 and a control means 19. The operation part 9 has: the plurality of touch keys 10 each composed of a pair of front and back electrode parts 11a and 11b on a top plate 1; an input means 12 for converting change of capacitance of each touch key 10 into voltage change; and a depression detection means 13 for detecting the depression of the touch key 10 based on the output of the input means 12. The control means 19 controls a current carried to a heating means 3 based on a signal inputted from the operation part 9. The operation part 9 is used for sequentially inputting the voltages of the respective touch keys 10, and for changing the sequences of input of the touch keys sequentially inputted at a predetermined cycle. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
