ードとする判定を行い、着信があった場合には受信モー
ドを連続受信動作モードとする判定を行う。<Function> Normally, while waiting for an incoming call, the handset is connected to the base unit and the power of the handset is charged. In this way, when the charging terminals and control terminals of the master unit and slave unit are connected together and the power supply of the slave unit is being charged by the charging power supply unit of the base unit, the charging detection unit indicates that charging is in progress. The incoming call control detection section detects whether there is an incoming call and outputs the detection result. Then, the reception mode determination unit receives these detection results and determines that the reception mode is set to the continuous pause operation mode if there is no incoming call, and sets the reception mode to the continuous reception operation mode if there is an incoming call. Make a judgment.

ドとする判定を行う。On the other hand, if the base unit and slave unit are not connected via the charging terminal and control terminal, the incoming call control detection section does not output the detection result, and the charging detection unit detects that the power supply of the slave unit is not connected to the base unit. If the battery is being charged by a charging power source other than the battery charger, it is detected that the battery is being charged, and if it is not being charged, it is detected that the battery is not being charged, and the detection result is output. and,
In response to these detection results, the reception mode determination unit determines that the reception mode is continuous reception mode if charging is in progress, and determines that the reception mode is intermittent reception mode if charging is not in progress.
そして、受信機部用電源制御部が上記受信モード判定部
の判定結果にもとづいて受信機部への電源の供給を制御

必要最小限の回路以外への電力供給のカットとを交互に
繰り返して行う。Then, the receiver section power supply control section controls the supply of power to the receiver section based on the determination result of the reception mode determination section. In other words, in the case of continuous reception operation, power is supplied to the entire reception system, in the case of continuous pause operation, the power supply is cut to all but the minimum necessary circuits such as timers, and in the case of intermittent reception operation, power is supplied to the entire reception system. Supplying power to the entire system and cutting off power supply to circuits other than the minimum necessary circuits such as timers are alternately repeated.

受信モードを連続受信動作モードとする。That is, when the handset 2 is connected to the base unit l and the power battery of the slave unit 2 is being charged by the charging power supply unit I5 of the base unit i,
Charging terminals 31 and 32 are at "high (H)" level,
Charge detection section 245 outputs an "H" signal to reception mode determination section 246. If no call is received on base unit 1 in this state,
The output of the incoming call detection unit 14 remains at the “H” level, and the incoming call control detection unit 244 outputs a “Ho” signal to the reception mode determination unit 246. When the base unit l receives a call, the incoming call detection unit 1
4 detects this and sets the control terminals 41 and 42 to "L" level. Then, the incoming call control detection unit 244 sets the output to the reception mode determination unit 246 to “L”. When the output of the charge detection section 245 is "H" and the output of the incoming call control detection section 244 is "H", the reception mode determination section 246 sets the reception mode to the continuous pause operation mode, and the output of the charge detection section 245 is set to "H".
When the signal is "H" and the output of the incoming call control detection section 244 is "L", the reception mode is set to the continuous reception operation mode.

２４６は受信モードを連続受信動作モードとする。On the other hand, without connecting slave unit 2 to base unit l,
When the power supply battery of the handset 2 is being charged by connecting the power supply battery to the charging terminal 32 of the handset 2, the charging terminal 32 is at the "H" level, so the charge detection unit 245 detects the "H" level. Output a signal. At this time, since nothing is connected to the control terminal 42, it is at the "L" level, and the output of the incoming call control detection section 244 remains at the "L" level. Therefore, the reception mode determination unit 246 sets the reception mode to the continuous reception operation mode.

することができる。In this way, when the handset 2 is placed on the base unit I and the power battery of the handset 2 is charged by the charging power supply unit 15 of the base unit while waiting for a normal call, the receiving mode is continuously suspended if there is no incoming call. The operation mode reduces the consumption of the power supply battery and therefore reduces the charging time. When an incoming call is received, the reception mode is changed to continuous reception operation mode, so the wireless line connection can be established immediately without any non-response time. On the other hand, if handset 2 is not placed on base unit I and is being charged using a charger other than the base unit, the reception mode will be set to continuous reception mode, so the wireless line connection will be established immediately without any non-response time. can be done. In addition, if handset 2 is not placed on base unit l and is not charging, set the reception mode to intermittent reception operation mode, for example, 100m5
Since the ec standby operation is an intermittent reception operation in which operation and 900m5ec pause operation are performed alternately, consumption of the power supply battery can be reduced.
