PURPOSE:To enable display of residual time, by setting a timer time using a numeral display disc within a display window provided on a dial while a display disc is turned to subtract during the operation of a timer. CONSTITUTION:When a timer is set and a timer start button is depressed, a start signal P6 of a timer starting means 6 moves to a L level from the H level and the resetting of a frequency dividing section 71 is released at a timer clock generating means 7 and a timer clock P7 for one frequency division cycle is outputted from the means 7. A disc position counter 92 receives the signal P7 to perform a decremental counting of counts at one frequency division cycle. On the other hand, a reversion signal generation circuit 81 receives the signal P7 and outputs a disc reversion signal P81 for one frequency division cycle to reverse a numeral display disc 104 by one step per min as disc driving signal P84. A residual time is displayed on a window section 101. |
