In FIG. 8, reference numeral 1 is a cordless telephone slave unit, which includes an antenna 2 and a control circuit unit 3. Reference numeral 4 denotes a power supply unit, which includes a battery 5 and a battery protection circuit 6. Reference numeral 7 is a charger including a charging circuit 8. In addition, the control circuit unit 3 of FIG.
In the figure, 9 is a control unit, 10 is a wireless unit, 11 is a voice processing unit, 12 is a voice input unit, 13 is a key input unit, and 14 is a display light emitting unit.

The operation of the conventional mobile radio apparatus configured as described above will be described. In FIG. 8, the battery 5 is connected to the charger 7 to be charged. At that time, when the control circuit unit 3 of the child device 1 is operating on the battery 5, intermittent reception may be performed in which reception and reception stop are repeated in order to reduce the consumption of the battery 5. Next, the call operation will be described. When making a call using the handset unit 1, the handset unit 1 is turned on, the talk button provided on the key input unit 13 is pressed, and the master unit (not shown) of the mobile radio unit and control signals, etc. To communicate. When communication with the base unit is established, capture the line and check the call tone. After sending the other party's telephone number to the line with a numeric keypad, speed dial button, redial button, etc., it becomes possible to talk to the other party. A control unit 9 that searches for a radio frequency for a call, and amplifies the voice for a call,

Next, an incoming call response when the slave unit 1 receives a call from the master unit, that is, a call is described. Cordless handset 1
When the incoming radio wave is received from the master unit, it is received by the antenna 2, and the control unit 9 causes the wireless unit 10 to perform amplification, frequency conversion and detection of the received signal. The voice processing unit 11 corrects the level and frequency characteristic of the received signal. Control unit 9
Detects that the received signal is an incoming call signal, and then outputs a signal to ring the incoming call bell to the display light emitting unit 14, a light emission signal to notify the incoming call by light, or a vibration signal to notify the incoming call by vibration. Then, the display light emitting unit 14 performs an operation of notifying an incoming call according to these signals. When speaking, press the receiving button on the main unit to talk. The call voice is input from the microphone forming the voice input unit 12, passes through the voice processing unit 11, is modulated by the radio unit 10, is radiated as a radio wave from the antenna 2, and is transmitted to the other party of the call via the master unit. To be done.

[0005]

However, in the above-described conventional configuration, when the power of the child device 1 is turned on, the power consumption of the battery 5 is reduced regardless of whether the child device 1 is being charged or not being charged. In order to do so, since intermittent reception is performed in which the reception stop state and the reception state are repeated for a certain period of time, when the handset 1 is in the reception stop state when the incoming call signal from the base unit is received, the handset 1 There is a problem that the incoming call operation cannot be performed until the next reception state is entered, and the response of the handset device 1 to the base device is delayed.

[0006] Therefore, an object of the present invention is to provide a mobile radio device which is easy to use and which can promptly answer an incoming call at the time of charging.

[0007]

In order to achieve such an object, the mobile wireless device of the present invention has a receiving unit for performing a receiving operation and a charging signal detecting unit for detecting whether or not the main body of the mobile wireless device is being charged. And a reception control unit that switches between the intermittent operation and the continuous operation of the receiving unit according to the signal from the charging signal detecting unit.

[0008]

With the above configuration, continuous reception is performed during charging and intermittent reception is performed during discharging. In addition, a display emission sound emitting section for displaying, lighting, outputting sound and voice of the mobile wireless device, a charging signal detecting section for detecting whether or not the main body of the mobile wireless apparatus is being charged, and a signal from this charging signal detecting section A signal control unit for controlling the display light emitting sound emitting unit is provided, and the power consumption is set to be in an operating state in which power consumption is large during charging and in a set state during discharging.

With the above arrangement, when the mobile radio is powered on and not being charged, operations such as intermittent reception, bell volume, light emission brightness, and vibration are in a low power consumption state, that is, the bell. Reduce the power consumption of the battery by lowering the volume, lowering the light emission brightness, or lowering the vibration level.
In addition, since there is not enough intermittent reception during charging when there is sufficient power, the incoming call signal from the base unit is output quickly, and either the bell volume is increased, the light emission brightness is increased, or the vibration amount is increased. By clarifying the incoming call signal, the incoming call response performance can be improved.

The operation of the mobile wireless device, that is, the cordless telephone configured as described above, will be described below.

In FIG. 1, when the secondary battery 19 that can be charged is installed in the slave unit 1, it is necessary to charge and use the secondary battery 19. Therefore, the charging signal detection unit 15 detects the charging voltage from the charging stand to the child device 1 and detects that the child device 1 is being charged. As shown in FIG. 2, the voltage applied to the charging terminal 18 from the outside of the cordless handset 1 passes through the noise prevention circuit 22 that eliminates malfunctions due to external noise, or attenuates to a level that does not hinder detection of the voltage. To a charge detection circuit 23 which converts the signal into a logic 1 or logic 0, a high or low signal. In response to the detection output of the charge detection circuit 23, the intermittent reception control unit 16 of FIG. 1 switches the reception unit 17 to continuous reception when it detects a charging state, and switches to intermittent reception when it is not charging. It is also possible to make the reception time ratio of the intermittent reception during charging larger than the reception time ratio when not charging.

Further, the built-in secondary battery 19 is charged from the charging terminal 18 of FIG. 2 through the backflow prevention unit 20 which prevents backflow from the battery 5. The thermistor 21, which is thermally coupled to the secondary battery 19, generates heat when the secondary battery 19 is charged, so that the thermistor 21 manages temperature for completion of charging and
The heat of the secondary battery 19 is converted into a resistance value and transferred to the charger 7.

In FIG. 2, the secondary battery 19 placed on the charging stand is either discharged until it cannot be operated, it is left slightly, or it is fully charged. Since the full charge is detected by measuring the voltage and the temperature, it is possible to switch from the intermittent reception to the continuous reception after the full charge is detected. As a result, when the battery is not fully charged, it may not be possible to secure the call time indicated in the specifications when receiving an incoming call, but when the battery 5 is fully charged, the incoming call was answered during continuous reception. When, there is an advantage that it is possible to talk for a time that satisfies the specifications.

FIG. 6 is a block diagram showing the configuration of a mobile radio device according to the second embodiment of the present invention, and FIG. 7 is a block diagram of a signal control unit of the mobile radio device according to the second embodiment of the present invention. In FIG. 6, reference numeral 15 is a charge signal detection unit similar to that of the first embodiment, 36 is a signal control unit for controlling the display contrast, the brightness of the light emitting body and the volume of the sounding body, and 37 is a display light emitting unit.

In FIG. 7, the signal control unit 36 includes a control microcomputer 38, a voice switching unit 39 for changing the volume and sound quality, an emission light amount switching unit 40 for changing the brightness and the light amount of the light emitter, and the contrast of the LCD or the plasma display. The display light amount switching unit 41 that changes the brightness is included.

A display unit such as a liquid crystal display, a plasma display, a CRT, etc. for displaying the telephone number of the other party and the operating state of the time can change the contrast and the brightness showing the lightness and darkness of the display, and the display of high contrast and bright But,
Low contrast, more power consumption than dark display. In addition, the brightness of the light emitting diode used for power-on, setting, and display of a call can be changed, and the bright display consumes more power than the dark display. Furthermore, as the sound volume of the ringing ringing sound when an incoming call is received, an alarm sound when a violating operation is performed, and a voice or a signal sound of the other party of the call is increased, the power consumption of the circuit increases.

When the charging signal detection unit 15 detects that the charging is being performed by connecting the cordless handset 1 to the charger 7, the power consumption of the display light emitting unit 37 increases, but the light emission of the display light emitting unit 37 becomes bright. The large ringer volume allows you to know an incoming call earlier, and does not make the called party wait for a long time. Then, the charging signal detection unit 15 detects that the battery is being charged, and the display light amount switching unit 41 brightens the display by increasing the light amount or increasing the brightness, and the emission light amount switching unit 40 causes the light emitting diode or the light bulb. To increase the brightness or increase the brightness, and the voice switching unit 39
The control microcomputer 38 controls either to increase the input power to the sounding body, the earphone, or the like. However, it is possible to set a state in which the power consumption is not increased. The increase in power consumption can be set so that the battery can operate when the battery capacity is fully charged, as in the first embodiment of the present invention. As described above, according to the configuration of the second embodiment, the low power consumption state can be set when the battery is not charged, and the high power consumption state can be set by using a sufficient power when the battery is charged.

[0024]

As described above, according to the mobile wireless device of the present invention, there is a margin of electric power in a low power consumption state such as intermittent reception and volume reduction when not charged, and in electric power when charged, as compared with a single battery operation. Therefore, it is possible to perform continuous reception or an operation of increasing power consumption by improving the volume and the display brightness, thereby making it possible to promptly receive an incoming call at the time of charging, improve responsiveness, and improve usability.
