PURPOSE:To make the residual time up to a set time easy to know by shortening the intervals of making preliminary announcing as it goes closer to the set time. CONSTITUTION:In the case of performing a residual timer function, first a fast feed key F is pushed and the content of a register 3 is set at a desired time and is inputted to a register 9. When the content of a subtraction counter 9 goes equal to the 1st storage content of a preliminary announcing time storage memory 13, a signal is outputted through a detecting circuit 15, and the noice signal announcing the residual time is outputted by a voice synthesizer 16, whereby the voice indicating the residual time is outputted 8. Thereafter, an address up circuit 14 indicates the address of the 2nd storage information and therefore when the content of the counter 9 goes equal to the 2nd storage content upon lapse of the prescribed time, again the voice indicating the residual time is outputted. Said storage contents are longer time intervals for the beginning and as it goes closer to the intended time, the time intervals are shorter. |
