TIME SETTING CONTROL DEVICE

摘要

PURPOSE:To constitute a setting key with the same structure and at the same position as other keys by prohibiting the resetting of time after a time inputting key is inputted until an input continuation counter is operated for a fixed time and immediately allowing the time resetting without prohibiting the resetting after no input is entered until a no-input continuation counter is operated for a fixed time. CONSTITUTION:A microcomputer 17 has a key input judging unit 18 to judge whether a time setting key 13 and a cooking selecting key 14 are pushed or whether they are in the pushed state or the released state. The time of a time counter 21 is reset after t1sec (e.g., 1sec) since the setting key 13 starts to be pushed under the control of an input continuation counter 19 measuring the time that the time setting key 13 is kept pushed and a no-input continuation counter 20 measuring the time after the pushed setting key 13 is released on the contrary. When the setting key 13 is released, it resets the time without waiting t1sec until t2sec (e.g., 4sec) elapses.
