Abstract

PURPOSE:To attain low power consumption and to improve the operability by making a control section inactive in the standby of an incoming call, stopping the feeding to a transmission reception section and depressing a talking button so as to restart the operation of the control section and the power supply to the transmission reception section when an incoming call arrives. CONSTITUTION:When a power mode changeover switch 205 is turned on to obtain the power saving mode and a high level is outputted to a BS port of a CPU 202, an output of a C1 port goes to a low level. The output is fed to a base of a transistor(TR) 2, no voltage is applied between the base and emitter, no collector current flows and the power supply to a reception section RX and a transmission section TX is stopped. Moreover, in the standby of the power saving mode, when the presence of an incoming call is informed by a ringing such as a ringer, a talking button 206 is depressed to input a high level to a talking control input terminal Ts to restart the operation of the CPU 202 to energize the reception section RX and the transmission section TX. Thus, low power consumption is obtained, the service life of the battery is extended and the operability is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cordless telephone device, and in particular, to power supply control of a cordless telephone device equipped with a power supply circuit that can be used continuously for a long time due to low power consumption. Regarding the method.

[Prior art and its problems]

In recent years, cordless telephone devices can be used continuously for long periods of time,
Moreover, there is a demand for something with excellent operability.

FIG. 2 is a block diagram of a cordless telephone device for explaining a conventional example. The numbers in the diagram are 1 for the battery, 2 for the mechanical power switch such as a toggle switch, 3 for the power supply circuit, and 4 for the power supply circuit.
is a control section, 5 is a power line, and 6 is a control line. Further, RX is a receiving section, and TX is a transmitting section. When the power switch 2 is in the ON state, a current flowing from the battery 1 is supplied from the power supply circuit 3 to the receiving section RX, the transmitting section TX, and the control section 4 via the power line 5. Now power switch 2
When the power supply circuit 3 is in the ON state, the power supply circuit 3 adjusts the amount of current supplied in each of the transmission state, reception state, and standby state. However, if the power switch 2 is always kept in the ON state as in this method, the current consumption is large, making it impossible to use the device for a long time. Therefore, as a method to reduce the current consumption in the standby state, intermittent reception that stops power supply to the receiving unit RX at fixed intervals,
Alternatively, when on standby, the power switch 2 is turned off and a linker is sounded by a connection device jml (not shown) to notify the user of an incoming call.

However, the intermittent reception method described above is insufficient to solve the problem of reducing current consumption, and turning off the power switch 2 during standby means that when transmitting or receiving, you must press the power switch 2 again before making a call. It had the problem of having to press a button, making it difficult to operate.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a cordless telephone device that achieves low power consumption, allows continuous talk for a long time, and is easy to operate.

[Means for solving problems]

In order to solve the above-mentioned problems, in a power supply sub-leg method for a cordless telephone device consisting of a handset consisting of a power supply section, a control section, an electronic switch, and a transmitting/receiving section, and a handset connection device, when waiting for an incoming call, the control section is inoperable, and the power supply to the transmitter and receiver is stopped using an electronic switch.Incoming calls are detected by sounding the linker of the hand sent connection device, and when there is an incoming call, the control unit is activated via the power supply unit. By pressing the call button connected to the control unit, the operation of the control unit is resumed, and the power supply to the transmitting and receiving unit is also restarted, so that the transmitting and receiving unit is placed in the transmitting and receiving state.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 (a) and Figure 2 (b) show an embodiment of the handset of the cordless telephone device of the present invention, and Figure 1 (a) is a schematic diagram of the circuit; (b) is the 1st I
21(a) is an example of a detailed circuit diagram of FIG.

In each number, 101 is a battery, 102 is a control section, 103 is an electronic switch, RX is a receiving section, and TX is a transmitting section. The current from the battery 101 is supplied to the control circuit 102 when in a call state.
A power supply signal 104 is issued, and the electronic switch 103 supplies current required for transmission and reception to the receiving section RX and the transmitting section TX. The electronic switch 103 is composed of a transistor or the like. Therefore, in the standby state, the receiving section RX and the transmitting section T
Since power is not supplied to X and is used only for holding the stored contents of the storage means in the control unit 102, the power consumption is extremely low and it is possible to make continuous calls for a long time. In addition, during standby, an incoming call from an outside line is notified by a linker or the like on the side of a connecting device (not shown).Next, a more detailed explanation will be given with reference to FIG. 1(b). First, the numbers in the diagram of FIG. 1(b) will be explained. First, 201 is a battery, 202 is C
PU, 203 is a keyboard, 204 is a keyboard 203
205 is a power mode changeover switch, 206 is a call button, RX is a receiving section, TX is a transmitting section,
R1-R5 are resistors. Also, Trl, T r2
is a transistor, and 5TABI and 5TAB2 are stabilizers.

Note that the transistors Tri and Tr2 correspond to the electronic switch 103 in FIG. 1(a), and the CPU 202 corresponds to the control unit 102 in FIG. 1(a).

In the present embodiment ρ1, the cordless telephone device has two types of power modes, a normal mode and a power saving mode, and switching to both modes is performed by a power mode changeover switch 205 of a sliding type switch.

In the normal mode, by turning off the power mode selector switch 205, LOW is output to the BS port of the CPU 202.
When LOW is output to this BS boat, the CPU 202
Intermittent reception is performed under the control of the wireless connection device, in preparation for a wireless call from the cordless connection device.

In the power saving mode, by turning on the power mode changeover switch 205, a high signal is output to the BS boat of the CPU 202, and when a high signal is output to the BS boat, the receiving unit RX
, power is not supplied to the transmitter TX during standby, and the operation of the CPU 202 is stopped during standby. When notified of an incoming call by a linker or the like of the cordless connection device, simply pressing the call button 206 restarts power supply to the receiving section RX and transmitting section TX, thereby making the transmitting/receiving condition deaf.

In order to enter the power saving mode, the power mode switch 205 is turned on and a high signal is output to the BS boat of the CPU 202, and the output of the C1 boat becomes low. Since the output from the C1 boat is applied to the base of the transistor Tr2, when the output from the C1 boat is low, a voltage is applied between the base and the emitter, and the collector current does not flow, so power is supplied to the receiving section RX and transmitting section TX. will be stopped.

Also, when you are on standby in power-saving mode, when you are notified of an incoming call by a ringer on your cordless connection device,
By pressing the call button 206, the call control input terminal T
High is input to s to restart the operation of Cp U202 and output I i and qh from the C1 boat. Therefore, at this time, a collector current flows through the transistor Tr2, and is stabilized by the stabilizer 5TAB2. C
The movement 1t of the PU202 is transmitted to the receiving section R by the output of the C1 boat.
In addition to controlling the power supply to the X and transmitter TX, it also transmits and receives data (transfers and receives data, etc.) between the C2 boat, C3 boat 1~ and the receiver RX and transmitter TX.5 The call has ended. Then, by pressing the end button 204 on the keyboard 203b, the wireless link with the cordless connection device is cut off, the output of the C1 port is set to Low, the power supply is stopped, and the operation of the CPU 202 is stopped.

〔effect〕

Based on the above configuration, when in power saving mode (in power saving mode) and standby mode, power is supplied to the transmitter and receiver, and the power is turned on to the power supply to the transmitter and receiver. However, in order to achieve extremely low power consumption, battery life is extended. Since restart and power supply can be resumed, it is possible to provide an extremely excellent cordless telephone device with one-on-one power supply.
