る。Now, for example, when the receiver calls and sounds when the battery voltage a drops and is close to the specified voltage indicated by the broken line as shown at A in FIG. 3A, the internal resistance of the battery causes The battery voltage a once drops below the specified voltage as shown by the waveform a in Fig. 3 (corresponding voltage and waveform are the same signal. The same applies below) (for example, when using an alkaline manganese battery with an internal resistance of 170 mΩ, an alarm If the current consumption at that time is 140mA, the voltage drop will be 23.8mV). However, when the ringing ends, the voltage returns to a value higher than the specified voltage. The signal b indicates the output of the comparator 8 in the above state. In this case, the state in which the voltage is lower than the specified voltage is stored by using the flip-flop circuit (F / F) 21 composed of two NAND circuits. It The signal c indicates that the flip-flop circuit 21 stores the state in which the battery voltage falls below the specified voltage. Further, the output c of the flip-flop circuit (F / F) 21
And clock pulse CLK (50Hz) through the AND gate 22 and its output d is added as the input of the counter 23 (eg NECμPD4040BC (trade name)), its output Q 2 , Q 6 , Q 7 and clock pulse (2kHz) At the output e of the AND gate 24 for inputting, the intermittent waveform of a pulse of 2 seconds is obtained for every 100 clock pulses of 50 Hz. However, while the receiver is ringing and the output i of the call signal processing unit 25 indicates "H", the counter 23 is reset via the OR gate 26 and does not operate. The output e of the AND gate 24 drives the alarm circuit 5 composed of the NPN transistor 28, the PNP transistor 29 and the speaker 30 as an output f via the OR gate 27 to obtain an intermittent alarm. Further, during the reception sound operation, the output g of the ringing sound cycle creating circuit 31 and the clock pulse CLK (2 kHz) are connected to the AND gate 32, and the output h thereof is input to the OR gate 27. As described above, the battery voltage drop warning signal e and the ringing tone signal h are passed through the OR gate 26 to operate and output the output f regardless of which signal is input. The output j of the reset switch is for resetting the flip-flop F / F21 via the OR gate 33 and the ringing frequency generation circuit 31 via the inverter 34. Even if the push switch 35 of the reset switch unit 9 is pressed to stop the ringing operation when the flip-flop circuit F / F21 is reset (when i is "H"), the call signal processing unit 24 does not reset. The output signal i is used as one input of the OR gate 33.
なお上記の説明において，断続波形ｅとは一定周期で断
続するように記しているが，断続周期は一定周期である
必要がないことはいうまでもない。In the above description, the intermittent waveform e is described as being intermittent at a constant cycle, but it goes without saying that the intermittent cycle does not have to be a constant cycle.
