Abstract

PURPOSE:To eliminate the need for the operation by the user of a slave set at the battery wear and to attain consecutive talking of an opposite party without movement of the user by selecting a channel to a voice storage equipment with a battery wear radio signal outputted from a battery wear slave set and storing a voice of a talking opposite party or implementing other operations. CONSTITUTION:Upon the detection of battery wear of its own equipment, a slave set 5 sends a battery wear radio signal, the signal is received by a connector 4 and a master set 1 selects a channel automatically to a voice storage device 7. Then the channel changeover is informed from the device 7 to a communication opposite party and the voice of a talking opposite party is stored in the device 7. As a result, the operation of the user of the slave set at the battery wear is not required and the talking is continued without the need of the user of the slave set to move to a remote telephone set.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a system cordless telephone device capable of controlling a plurality of communication paths.

BACKGROUND OF THE INVENTION FIG. 2 shows the configuration of a conventional system cordless telephone device. In the figure, a main device 1 can control two communication paths 2 and 3, one communication path 2 is provided with a connection device 4, and is further connected to a slave unit 5 by radio. A standalone telephone 6 is connected to the other communication path 3.

Next, the above conventional operation will be explained. In the figure, when the handset 5 runs out of charge during a call, an alarm sounding device (not shown) provided on the handset 5 is activated to alert the user. If the user wishes to continue the call, he operates the handset 5 to switch the call path from the handset 2 to the standalone phone 3, thereby transferring the call.

Problems to be Solved by the Invention However, with the conventional system cordless telephone device described above, in order to continue a call, the user has to operate the handset to transfer the call, which is cumbersome to operate. . Also, if the handset is far away from the standalone phone,
This was inconvenient because the user of the handset had to travel to the standalone phone. The present invention solves these conventional problems, and provides an advantage in that when the handset runs out of battery, data is transferred without any operation, and the user does not have to move to the standalone phone. It is an object of the present invention to provide a system cordless answering machine. 1. Means for Solving the Problems In order to achieve the above object, the present invention provides a handset that emits a wireless signal when the battery runs out during a call. and a connecting device that receives this wireless signal, a main device that receives the charge-out signal from the connecting device and switches the current communication path of the handset, and notifies the other party of the communication from the switched communication path. and an audio storage device that sends out an audio signal and then records the voice of the other party.

Therefore, according to the present invention, when the handset runs out of battery during a call, the handset automatically emits a wireless signal, and the connecting device that receives this wireless signal informs the main device that the battery runs out. A signal is issued, the main device switches the communication path to the voice storage device, and the voice storage device sends an audio signal to the other party to notify that the switch has been made, and then records the voice of the other party.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In the figure,
The main device 1 can control and switch between the two communication paths 2 and 3. A connecting device 4 is connected to one communication path 2,
Furthermore, a handset 5 is connected wirelessly. A voice storage device 7 is connected to the other communication path 3. The handset has a built-in detection device (not shown) that detects when the battery runs out. This detection device detects, for example, when a battery is running out of charge.
This voltage drop is detected in advance and a special wireless signal is emitted to indicate that the battery is running out of charge. The connection device has a detection circuit that detects the special wireless signal, and when detected, can output an electric signal to notify the main device that the battery is out of charge. The audio storage device includes a recording tape that works when the battery runs out, and a playback/recording device.

Next, the operation of the above embodiment will be explained. When the handset 5 runs out of charge during a call, a detection device built into the handset detects this deadness and issues a special radio signal. The connecting device 4 that has received this wireless signal sends an electrical signal to the main device 1 to notify that the battery is out of charge. The main device 1 switches the communication path 2 currently established between the handset 5 and the other party, and connects it to the communication path 3 on the voice storage device 7 side. At the same time as this switching, the audio storage device 7 is activated, and the first part of the recording tape is played back, and the previously recorded voice, for example, ``The battery of the handset has run out, so I'll call you later.'' I think so. Please tell me the continuation of your business and your phone number. The voice j is sent as an audio signal. Immediately after that, the recording tape starts recording, recording the voice of the other party's business and phone number. do.

According to the embodiment described above, even if the handset 5 runs out of battery during a call, the handset 5 automatically issues a wireless signal and the main device 1 automatically connects the call path to the audio storage device 7. It is possible to continue and record the conversation of the other party without requiring any operation by the user of the handset 5 or moving the user.

In the embodiments described above, the audio storage device 7 uses a tape to notify the other party that the call has been switched and records the other party's voice; An IC playback circuit or even an IC recording circuit can be used, and an optical disc or the like can also be used for playback or recording.Furthermore, the voice signal notifying the user of the switching is only the pre-recorded voice of the user. Alternatively, it may be a synthesized voice or a pre-arranged signal tone.

Effects of the Invention As is clear from the above embodiments, the present invention has the following effects.

(1) When the handset runs out of battery, the user does not need to operate the handset, and the handset automatically emits a wireless signal, thereby switching the communication path. Therefore, there is no need for the user to perform any operations.

(2) The voice storage device notifies the other party of the switched communication path using an audio signal, and the other party can record the continuation of the conversation in the voice storage device υ. Therefore, even if the handset is far away, the user can prevent the call from being cut off midway without moving.
