Abstract

PURPOSE:To prevent the drop in the battery voltage with less load applied to the battery by prohibiting the simultaneous drive operations with the preference given to the signals for advance drive, buzzer drive, lighting drive and the like simultaneously generated. CONSTITUTION:When the advance drive signal is generated with the reference signal oscillator 1, the divider 2, the waveform shaping circuit 3 and the like, the and gate is opened after a delay by a given time through the OFF delay timer 6 and the inverter 12. With such an arrangement, when the alarm drive signal is generated simultaneously with the advance drive signal from the alarm circuit 7 upon the coincidence of the time counter 8 with the set alarm time of the alarm memory 9 by the division output of the circuit 2, the advance drive signal is prefered through the gate 4 and the alarm drive is prohibited until the end of the advance drive. Likewise, the alarm drive signal is prefered to the lighting drive signal. Thus, no load due to the simultaneous drive is applied to the battery, thereby preventing any drop in the battery drop.
