FIG. 2 shows an example of the main body of the handset 2, that is, the handset 2 in which the circuit shown in FIG. 1 is incorporated. The lamp 26 shown in FIG. 1 is arranged in the upper portion of the handset 2, that is, near the transmitter 2L so that the light 26L shown in FIG. In addition, the lamp 28 shown in FIG. 1 is provided with the light 2 shown in FIG.
It is arranged in the lower part of the slave unit 2, that is, in the vicinity of the handset 2S so that 8L can be emitted. In addition, the lamp 28 is obtained by rotating a knob 30 provided at a lower end of the slave unit 2,
It is preferable to arrange so that the irradiation direction of the light 28L can be changed.

In the embodiment of FIGS. 1 and 2 configured as described above, when a power failure occurs while the slave unit 2 is placed on the charging stand 1, the voltage of the charging circuit 22 gradually decreases. To do. The microcomputer 24 outputs a high level power failure detection signal to the base of the transistor 25 in response to the gentle voltage drop. As a result, the transistor 25 is turned on, current is supplied from the voltage source + V to the lamp 26, and the light 26L is emitted upward from the lamp 26. Therefore, it becomes easy to confirm the position of the handset, that is, the handset 2.

When the slave unit 2 is lifted from the charging stand 1, the voltage of the charging circuit 22 suddenly drops. In response to this sudden voltage drop, the microcomputer 24 outputs a high-level handset lift detection signal to the transistor 27.

FIG. 3 shows an operation example of the microcomputer 24 of the embodiment shown in FIG. First, in step S1, the microcomputer 24 determines whether or not the slave unit 2 has been lifted from the charging stand 1, that is, whether or not the voltage of the charging circuit 22 has gently dropped. When the microcomputer 24 determines that the slave unit 2 is lifted from the charging stand 1, it detects that the voltage supplied from the charging stand 1 to the slave unit 2 is zero (step S2), and the handset is set to the transistor 27. A lift detection signal is output, the transistor 27 is turned on, and the lamp 28 emits light 28L.

When the microcomputer 24 detects that the voltage supplied from the charging stand 1 to the slave unit 2 is zero, it puts it in the on-hook state (step S5). Then, when there is a key operation within 10 seconds (YES in step S5), the microcomputer 24 puts the telephone in a call-enabled state. Then, when the child device 2 is returned to the charging stand 1 (YES in step S7), the microcomputer 24 turns off the hook 28 (step S8) and turns off the lamp 28 (step S10).

When there is no key operation within 10 seconds after entering the on-hook state (NO in step S5), the microcomputer 24 enters the off-hook state (step S8). In addition, the microcomputer 24 does not operate a key within 10 seconds after being in the on-hook state, and
When the minutes have elapsed, the lamp 28 is turned off (step S10).

The microcomputer 24 executes step S
1 does not detect the gradual decrease in the voltage of the charging circuit 22 and detects a sudden decrease in the voltage of the charging circuit 22, that is, a power failure in step S11, the supply voltage from the charging stand 1 to the slave unit 2 becomes zero. When it is detected (step S2), a power failure detection signal is output to the transistor 25, the transistor 25 is turned on, and the light 26L is emitted from the lamp 26 (step S3). Then, the microcomputer 24 uses the steps S4 to S10 described above.
