However, when the handset (5) is off-hook and the hook switch (2) is closed by an incoming or outgoing call, telephone current flows through the speech network circuit (4) and the diode bridge circuit (1), and the handset (5) )
To talk to the other party. At this time, if the current supplied to the speech network circuit (4) is sufficient, the reference voltage (Vref) is higher than the reference voltage of the Zener diode (7), and an H level output is generated from the comparator (6). In order to make the transistor (9) conductive, the transistor (8) is also conductive and the secondary battery (11) and the rechargeable emergency light (12)
Is charged. At this time, the reference voltage (Vref) due to excessive current flowing through the secondary battery (11) and the rechargeable emergency light (12)
As the output of the comparator (6) decreases and the collector current of the transistor (9) decreases, the current flowing through the transistor (8) decreases, and the secondary battery (11) and the rechargeable emergency light (12) decrease. ) Is also reduced. As a result, the reference voltage (Vref) increases, and the drive voltage (VDD) to the speech network circuit (4) also increases. By repeating the above operation, the reference voltage (Vref) and drive voltage (VDD)
Is maintained constant, and the rechargeable battery (11) and rechargeable emergency light (12) except for the current required for the speech network circuit (4)
Is stored in The utilization device (12) is not limited to an emergency light, but may be another device.
