PURPOSE:To know residual time distinctly by announcing the residual time preliminarily prior to arrival at the set intended time. CONSTITUTION:In the case of performing an alarm function, first a fast feed key F is pushed and the content of a register 3 is set at a desired alarm time. Thence, an alarm set key S2 is pushed to input the content of the register 3 to an alarm time register 5. The content of an alarm time register 5 is processed with a substraction processor 8, by which the contents showing 5min before and 10min before of the alarm time are inputted respectively to a 5min before time register 6 and a 10min before time register 7. The contents of these registers 5, 6, 7 and the content of a time counter 10 are inputted to a detecting circuit 13, and when they coincide, the corresponding voice signal is outputted by a voice synthesizer 14. |
