<p><P>PROBLEM TO BE SOLVED: To simultaneously exert a timer operation function in a plurality of desired heating parts among a plurality of heating parts without increasing the number of numerical display elements, an inner timer of a control IC, or a ROM area for timer processing execution. <P>SOLUTION: One of operation times set separately for two heating parts is displayed in a residual time display means 11a. In this case, a longer operation residual time in the two operation residual times is counted by one timer counter 4 to be displayed, while a solution found by calculation of a difference between the longer operation residual time and a differential between the longer operation time and the shorter operation residual time, which are previously stored by a storage means 5, is displayed as the shorter operation residual time. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
