Title: Small electronic appliance with battery life alarm function
Inventor: MORISHIGE MORIO
IPC: G01R19/155
Filed: 1981-12-18
Abstract: PURPOSE:To eliminate misjudgement of the battery replacement time with an appropriate alarm of the battery life by performing an alarm on the life of the battery only when drop in the voltage of a battery is attributed to the life of the battery, excluding a temporary one due to the driving of a heavy load. CONSTITUTION:The output of a NOR gate 17 is fed to a display 9 as signal for giving the alarm of the battery life. When the output voltage of a battery 1 is slightly larger than -2.5V during non-driving of a lamp 10, it takes time to return to -2.5V even after the driving of the lamp 10 is released. In this case, the detection signal l stays at ''1'' for a long time after the release of the driving of the lamp 10. When ten minute elapses after the output voltage of the battery 1 drops with the driving of the lamp 10, a pulse signal is outputted from a delay circuit 14 and provided to a latch circuit 15 through an AND gate 12. Thus, the output of the NOR gate 16 goes to ''1'' to give the alarm of the battery life.
