DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an incoming call notification device for notifying a user when a telephone receives an incoming call.

[Technical background of the invention]

Conventionally, it is known to use a cordless telephone that is wirelessly connected to a parent telephone. This type of equipment was constructed as shown in FIG. A wireless telephone connection device 1 is connected to a wired telephone line 7 extending from an exchange (not shown), and a wired telephone 2 is connected to this wireless telephone connection device 1. Further, 3 indicates a cordless telephone. Wired telephone port 1
When there is an incoming call via llI7, a bell rings on the wired telephone 2. At this time, the wireless telephone connection device 1 sends an incoming call signal to the =-dress telephone 3 via the wireless line, so that the cordless telephone 3 also rings. From now on, the wired telephone 2 can also respond, and the cordless telephone 3 can also respond. Here, when the cordless telephone 3 responds, the transmitting section of the wireless telephone connection device 1 sends the audio signal sent via the wired telephone line 7 to the cordless telephone 3, and the receiving section sends the voice signal sent from the cordless telephone 3 to the cordless telephone 3. Receive the sent audio signal. On the other hand, the transmitting section of the cordless telephone 3 transmits the voice signal input from the handset of the cordless telephone 3 to the wireless telephone connection device 1, and the receiving section receives the voice signal sent from the wireless telephone connection device 1. As a result, it becomes possible to talk to the other party using the cordless telephone 3.

[Problems with background technology]

However, with the above configuration, although the cordless telephone 3 can be carried and installed anywhere, it is too large for the user to carry, and for example, when going out to the garden, it may be necessary to place the cordless telephone 3 in a place a little far away from the user. I had no choice but to put it in. Therefore, even if the bell of cordless telephone 3 rings when a call arrives, cordless telephone 3 or wired telephone 2
If the user is located far away from the telephone, the caller may have stopped making a call and the ringing of the bell may have stopped.

Furthermore, the transmitting section of the boondless telephone 3 consumes a lot of current (
When long-term phone calls are frequently made, the battery built into the cordless telephone 3 deteriorates quickly (there is a drawback that the battery must be replaced and charged frequently).

[Purpose of the invention]

The present invention was devised in view of the above-mentioned drawbacks of the conventional devices.The purpose of the present invention is to provide an incoming call device that is small and lightweight, is conveniently portable, and is capable of answering incoming calls by remote control. [Summary of the Invention] Therefore, the present invention provides an incoming call signal transmitter that is connected to a wired telephone line, detects an incoming call from the wired telephone line, and sends out an incoming call signal. and loop closing means for detecting an incoming call response signal and closing a loop with the exchange connected to the wired telephone line; and an incoming call from a mobile device, which is equipped with a notification sound generating means that detects an incoming call signal and generates a notification sound, and an incoming call response signal generating means that detects a button operation and sends an incoming call response signal. This constitutes a notification device and achieves the above purpose.

[Embodiments of the invention]

FIG. 3 is a block diagram of main parts of the connection device 4 and the notification device 6. In the figure, 9 in the connection device 4 indicates a control section, which takes in necessary data and controls each section. The control section 9 detects a 16 Hz calling signal via the wired telephone line 7, turns the switch SW3 to the transmitting section TX4 side, and instructs the transmitting section TX to send out an incoming call signal. Transmitter TXφ1
A signal modulated by the incoming call signal is sent out. Further, after receiving the command to send out the incoming call signal, the control unit 9 turns the switch SW3 to the receiving unit RX4 side and waits for the arrival of the incoming call response signal sent out from the notification device 6. When a signal modulated by the incoming call response signal arrives, the receiving unit RX4 receives it, demodulates it, and notifies the control unit 9 of the arrival of the first incoming call response signal. As a result, the control unit 9 closes the switch SW2, closes the loop with the exchange, and puts the line on hold for a certain period of time.

Further, 10 in the notification device 6 indicates a control section, and this control section 10 takes in necessary data and controls each section.

The control unit 10 sets the switch SW4 to the reception unit RX during standby.
Turn it to the e side. The receiving unit RXs receives the modulated signal by the incoming call signal, demodulates it, and notifies the control unit 10 of the arrival of the incoming call signal. Thereby, the control unit 10 sends out a notification sound signal to the speaker SP. As a result, a notification sound is generated from the speaker SP. From now on, the control unit 10 monitors the operation of the button 8, and when the operation of the button 8 is detected, the transmitter TX6
At the same time, the switch 8W is ordered to send an incoming call response signal to
4 to the transmitting section TX side. Actually, the control section 9 has the configuration of a microcomputer as shown in Fig. 4.
Further, the microprocessor 21 controls each section according to the program shown in the flowchart of FIG. 6 stored in the main memory 23. Figure 4 will be explained. A main memory 23 is connected to the microprocessor 21 via a memory bus 22, and an input port 25, an output port 26, and input ports 27 and 28 are connected via an I10 bus 24. A receiving section RX4 is connected to the input port 25, and a transmitting section TX is connected to the output port 26.

is connected to the input port 27, a switch SW2 is connected to the input port 27, and a switch SW3 is connected to the input port 28.

The control section 10 has a microcomputer configuration as shown in FIG. 5, and a microprocessor 31 controls each section according to the program shown in chart 70 of FIG. 7 stored in the main memory 33. . FIG. 5 will be explained. A main memory 33 is connected to the microprocessor 31 via a memory bus 32, and an input port 36, an output port 37, an output port 38,
An input boat 39 is connected. A receiver RX is connected to the input port 35, and a button 8 is connected to the input port 36.
is connected to the output port 37, a transmitter TXe is connected to the output port 37, a speaker SP is connected to the output port 38 via an analog switch 51 and an amplifier 52, and a switch 8W4 is connected to the input port 39.

The control unit 9.10 configured as described above is shown in FIGS. 6 and 7.
This will be explained with reference to the figures.

First, when starting, the control section 9 monitors whether or not 16 call signals have arrived via the wired telephone line 7, as shown in step 101 in FIG. Control unit 9
When detecting the 16 call detection signals, the process branches to YES in step 101 and proceeds to step 102. In step 102, the control unit 9 turns the switch SW3 to the transmitter TXJIII, and proceeds to step 103, where the controller 9 turns the switch SW3 to the transmitter TXJIII.
Order the sending of an incoming call signal to X. As a result, the transmitter TX sends out a signal modulated by the incoming call signal.

At this time, the control unit IO starts the operation according to chart 70 in FIG. 7, and in step 201 monitors whether an incoming call signal is detected in the receiving unit RX. Here, when a signal modulated by the incoming call signal arrives at the receiving unit RX, the receiving unit RX receives and demodulates it, and notifies the control unit 10 of the arrival of the incoming call signal, so the control unit 10 steps The process branches to YES in step 201 and proceeds to step 202. In step 202, the control unit 10 sends a notification sound signal to the speaker SP, and the speaker SP generates a notification sound. Next, the control unit 10 monitors whether or not the button 8 is operated in step 203, and if the button 8 is not operated, the NO button is pressed.
The process branches to step 204, where it is checked whether a predetermined period of time has elapsed since the reception of the incoming call signal.

This predetermined time is a time sufficient for the user of the notification device 6 to respond normally, and is a time to wait for the user's response.

Therefore, before the predetermined time elapses, the process branches to NO in step 204 and returns to step 203 to continue monitoring button operations, and after the predetermined time elapses, it is assumed that the user is unable or unwilling to respond. The process branches to YES in step 204 and returns to step 201.

While the control section 10 is performing the above operations, the control section 9 turns the switch SW3 toward the receiving section RX4 in step 104, and turns the switch SW3 toward the receiving section RX4 in step 105.
monitors whether an incoming call response signal is detected. Here, if no incoming call response signal is detected, the process branches to NO and proceeds to step 106, where it is checked whether the handset has been picked up. Although not shown in FIGS. 3 and 4, the control unit 9 is configured to receive hook information from the wired telephone 2 (
Specifically, the microprocessor 21 receives hook information via an unillustrated input port), and based on this information, it checks whether the handset has been picked up (whether the handset has gone off-hook or not. If the handset is not picked up, the process branches to No, proceeds to step 107, and the control unit 9
continues to monitor whether a 16HF/) call signal has arrived via the wired telephone line 7. Here, 16H
If the 1 call signal has arrived, the process branches to YES and returns to step 105. Further, in step 107, when the 16 Hz calling signal no longer arrives, the calling side has stopped making a call, so the process branches to NO and returns to step 101. Further, the control unit 9 performs step 10.
If the handset is picked up while executing the loop operation from step 5 to step 107, the process proceeds from step 106 to step 107, where the control unit 9 monitors the end of the call by checking whether the handset is returned. do. If it is detected in this step 108 that the handset has been put back on, the answer is YES.
The process branches to step 101, and the arrival of a new call signal is monitored.

When the button 8 of the notification device 6 is operated while the control unit 9 is executing the loop operation from step 105 to step 107, the control unit io detects this and executes the loop operation from step 105 to step 107.
3 branches to YES, proceeds to step 205, stops the generation of notification sound by the speaker SP, and switches the switch SW4 to the transmitter TX.

Fold it to the side. Furthermore, the control unit 10 proceeds to step 206 and instructs the transmitting unit TX@ to send out an incoming call response signal.

As a result, the transmitter TX@ sends out a signal modulated by the incoming call response signal. Next, the control unit 10 performs step 2
At step 07, the switch SW4 is turned to the receiving section RXc side, and the process returns to step 201.

The signal modulated by the incoming call response signal reaches the receiving section RX of the connection device 4 and is demodulated. When the receiving unit RX notifies the control unit 9 of the arrival of the incoming call response signal, the control unit 9 branches to YES in step 105 and proceeds to step 109. In step 109, the control unit 9 closes the switch 8Wz and creates a loop with an exchange (not shown) connected to the wired telephone line 7, thereby placing the line on hold. Furthermore, the control unit 9 proceeds to step 110 and monitors whether the handset is picked up. Here, if the handset is not picked up, the process proceeds to step 111, and the control unit 9 checks whether a predetermined time has elapsed since the line was put on hold.

This predetermined time is a time to prevent the line from remaining on hold forever. In step 111, if the predetermined time has not elapsed, the process returns to step 110.

In this way, when the handset is picked up while the control unit 9 is executing the loop operation of steps 11G and 111, the process branches to YES in step 110 and proceeds to step 108, where the end of the call is monitored. It will be done. Further, when the above-described loop operation is performed, when a predetermined time has elapsed, the process branches to YES in step 111, and the process branches to YES in step 112.
Proceed to. In step 112, the control unit 9 opens the switch SW2, disconnects the line, and returns to step 101.

By operating in this way, the control section 9 includes an incoming call signal sending means 41 that detects an incoming call from the wired telephone line 7 and sends out an incoming call signal 45, as shown in FIG. It functions as a loop creation means 42 that detects a response signal 46 and creates a loop for a predetermined time in the exchange connected to the wired telephone line 7. Further, as shown in FIG. 8, the control unit 10 includes a notification sound generating means 44 that detects an incoming call signal 45 and generates a notification sound 43, and detects the operation of the button 8 and sends out an incoming call response signal 46. It functions as an incoming call response signal generating means 47.

Since the incoming call notification device e described above does not have a transmitting/receiving function, it can be configured to be small and lightweight and can be carried. When the user carries the notification device 6 and receives an incoming call and a notification sound is generated from the speaker SP, the user operates the button 8 to put the line on hold, and then goes to the location where the wired telephone 2 is installed. , you can pick up the handset and talk. Therefore, it is possible to reduce the number of cases in which the caller stops making a call due to impatient waiting for the other party's response.In addition, in the notification device 6, the speaker 5PIC generates a notification sound and the transmitter TX sends an incoming call response signal. There is only a large amount of power consumption when transmitting a call signal, and the built-in battery is not easily consumed.Furthermore, control signals such as an incoming call signal and an incoming call response signal are transmitted between the connection device 4 and the notification device 6. Since it is only necessary to transmit and receive signals, it is possible to narrow the band and obtain a high signal.

Therefore, unlike a cordless telephone, it is not necessary to transmit and receive voice signals, so power consumption can be reduced and the circuit can be made smaller.

Note that the control signal transmitted and received between the connection device 4 and the notification device 6 may be a digital signal or a tone signal. Further, the connection device 4 and the notification device 6 may be provided with a display indicating line hold or a button for resetting the line hold (which may be used in conjunction with the button 8) to add a line hold release function.

Furthermore, by adding a voice synthesis function to the control unit 90 or adding it to the control unit 9, when the line is on hold, you can receive messages such as ``Please wait a moment'' or ``Please try again after a while.''
, etc., or music, etc., may be sent back to the calling party.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide an incoming call alarm that is small, lightweight, and convenient to carry, and it is convenient to be able to respond to an incoming call by remote control.
