If a key operation is performed in step 51, whether or not the slave unit 1 is placed in the master unit charger 3
The pick-up detection means 245 determines whether the handset information transmission charging terminal 423 of the handset is connected to the base information transmission charging terminal 456 of the base unit 2 (S52). Move to outgoing.

  If it is detected in step 52 that the device is placed, the placement detection means 245 notifies the signal sending means 244 of the placement information (S53). Then, the signal sending means 244 controls the charging power supply circuit 31 at high speed, generates a signal for starting the wireless connection, and sends it from the parent device information transmission charging terminal 456 (S54).

  The signal for starting the wireless connection is received by the signal receiving means 145 via the handset information transmission charging terminal 423 of the handset 1 shown in FIG. 4 and transmitted to the wireless sound control means 141 to be wireless sound control means. In 141, the audio processing circuit 12 and the wireless unit 13 are operated to start wireless connection from the child device 1 to the parent device 2 (S55).

  When the wireless connection from the slave unit 1 to the master unit 2 is started, the transmission monitoring unit 242 of the master unit 2 shown in FIG. 2 starts a built-in timer (S56), and monitors the key detection unit 243 and the pickup detection unit 245. Then, it is determined whether pick-up has been detected from the pick-up detection means 245 or the line connection has been confirmed from the wireless voice line control means 241 within a certain time (S57).

  If it is determined in step 57 that no pick-up has been detected from the pick-up detection means 245 or if the line connection cannot be confirmed from the radio voice line control means 241, the radio unit 23 is disconnected (S58). Thereby, it is possible to avoid continuation of the erroneous wireless connection.

  In step 57, if the pick-up is detected from the pick-up detection means 245 or if the line connection is confirmed from the radio voice line control means 241, the voice processing circuit 22 of the master unit 2 and the voice processing circuit 12 of the slave unit 1 are connected. Control is performed to form a communication path between the slave unit 1 and the master unit 2 (S59), thereby enabling a call.

  In the present embodiment, when the slave unit 1 is placed on the master unit 2, if a preset display operation of the master unit 2 or an operation of designating the other party is performed, a signal for starting a wireless connection in the power supply circuit Is transmitted from the master unit 2 to the charging circuit unit of the slave unit 1 to start wireless connection. Thereafter, it is detected that the slave unit has been picked up from the master unit by a terminal for charging information transmission of the master unit and the slave unit, but at that time, since the wireless connection has already been established, the telephone is immediately ready. Accordingly, it is possible to eliminate the wait due to the connection time peculiar to cordless when the slave unit is picked up from the master unit from the transmission preset state.

  In addition, since the information transmission charging terminal can transmit information from the parent device to the child device, it is possible to delete the pick-up detection switch that has been conventionally required in addition to the charging terminal.
