And a state notification unit 901 that notifies the charger 910 of the use state.

A charger 910 has a charging current control unit 911 for controlling charging current and a rectifying unit 912 for converting AC to DC.

Next, the operation of the present embodiment will be described with reference to the flowchart of each processing.

FIG. 2 is a flowchart showing a call termination process of the control unit 109 of the present embodiment.

First, in a call state (S201), when it is detected that the external handset 20 is connected (S202), the voice switching unit 104 is controlled to connect a voice signal to the external handset 20 side. (S203). In this case, only when the end key in the keypad 114 is pressed (S204), the end process is performed (S208), and the information as to whether or not the end is placed on the charging stand (charger) 910 is indicated by the end. Avoid involvement in processing. After the end-of-call processing, the mode shifts to the standby mode.

On the other hand, when it is detected that the external handset is not connected (S202), the voice signal is connected to the built-in handset (S205). In this case, the call termination process is performed both when the terminal is placed on the charging stand (S206) and when the call termination key in the keypad 114 is pressed (S207) (S208).

When the wireless telephone device 100 is in a communication state,
10, when communication is continued even when placed on the charging stand 910, the communication is continued and the state notification unit 901 is provided.
Notifies the charging current control unit 911 that communication is in progress. The notified charging current control unit 911 supplies a higher current than when the wireless telephone device 100 is in the standby state.
When the wireless telephone device 100 ends the communication, the status notifying unit 901 notifies the charging current control unit 9 that no communication is being performed.
Notify 11 The notified charging current control unit 911 supplies the charging current for standby. In the example described here, there are two modes of the communication state and the standby state and two charging currents corresponding thereto, but any number of communication modes and charging currents are possible.

0 is detected (S30
9), a calling process is performed (S311). When the call key is not placed on the charging stand 910, when a call key in the keypad 114 is pressed (S310), a call process is performed (S311).

FIG. 4 is a flowchart showing an incoming call response process of the control unit 109 of this embodiment.

First, in the standby state (S40)
1) When there is an incoming call notification (S402), the external handset 2
It is determined whether 0 is connected (S403). When connected, the audio signal is transmitted to the external handset 2
The connection is made to the 0 side (S404).

In this case, if it is placed on the charging stand 910 (S405), it is removed from the charging stand 910 (S4).
06) or when the response key is pressed (S407),
A response process is performed (S412). If the terminal is not placed on the charging stand 910, the calling process is performed by pressing the response key (S407) (S412).

On the other hand, when the external handset 20 is not connected, the voice signal is connected to the built-in handsets 105 and 106 (S408). Then, it is determined whether or not it is placed on the charging stand 910 (S409). If it is placed, it is detected that it has been removed from the charging stand 910 (S410), and a response process is performed (S412). ). If it is not placed on the charging stand 910, a response process is performed when a response key in the keypad is pressed (S411) (S412).
