Description

The present invention relates to a cordless telephone device having an answering machine function.

[Prior Art] Conventionally, a cordless telephone having an answering machine function has been used in various places. For example, a message is stored in a recording IC and a message is recorded on a recording tape. Storage control of a message and a message is performed from a cordless telephone handset. In this case, since the cordless phone wirelessly connects the master unit and the slave unit, the slave unit controls the master unit by transmitting the control signal, and the master unit decoding the control signal performs the necessary control. It has become.

A telephone of this type records necessary messages and messages and sets them in an answering / answering mode to send necessary messages and messages to a caller on the central line in response to an incoming call.

[Problems to be Solved by the Invention] However, in such a conventional device, since control from the slave unit to the master unit is performed by a control signal, recording is started by the control signal for starting recording, and the recording is stopped. Recording is stopped by a control signal that turns on, but when a control signal for stopping recording is received, part of the control signal is recorded until recording stops, and this is played back when responding. However, there is a problem that it gives a caller on the outside line an unpleasant feeling.

[Means for Solving the Problem] In order to solve such a problem, the present invention does not reproduce a recorded control signal.

[Operation] For recording ICs, by rewriting the stop address, playback will stop in the area before the area where the control signal was recorded. In the case of a recording tape, other information will be recorded in the area where the control signal was recorded. Is overwritten and the control signal is erased.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention.
M is a master unit, and the direct current from the station supplied through the external line terminal L is rectified by the diode 1 and is internally supplied as a direct current having a constant polarity regardless of the connection polarity of the station line. When an incoming call is received, it is detected by the incoming call detection circuit 7 via the diode 6 and supplied to the CPU 9. The call signal is transmitted to the handset S via the call circuit 3, the wireless transmission / reception unit 17, and the antenna 18. In addition, 8 is a dial IC, 2 is that
Transistors controlled by IC, 4, 5 capacitors, 10 PB receiver, 11 cassette mechanism, 12 line signal detector, 13 recording IC, 16 amplifier, 15 speaker.

The handset S is connected to a wireless transmission / reception unit 31 via an antenna 30, and has a response message key for storing a response message, a response message deletion key for deleting the message, a recording key for starting recording of a message, and a recording of a message. There is a key 37 having a stop key for stopping, a dial key, and other function keys, and the CPU 36 performs control corresponding to each key. Others 32 and 33 are capacitors, 34 is a receiver, 35 is a transmitter, 38 is an amplifier, and 39 is a speaker.

FIG. 2 is a flow chart showing the operation of this device.
In the figure, initial processing is performed in step 100,
Incoming call processing is performed in steps 101 to 107, but since step 101 is not receiving an incoming call during control from the child device, step 103 is performed.
In step 110, the processing for clearing the incoming call count is performed.
Then, it is judged whether or not the data is received from the handset.
Since the control is performed by the control signal, it is determined that the data is received from the handset during the control, the data is determined as the response message data in step 111, the response message is not being recorded in step 112, and the response message is determined in step 113. If it is determined that the input has not been completed, a recording IC response message recording start processing is performed in step 114, and other processing shown in step 115 is performed. If it is determined in step 113 that the response message has been input, the recording IC response message reproduction process in step 120 is performed.

If it is determined in step 112 that the response message is being recorded, the response message key is operated at the timing to stop the recording of the response message.
The process of stopping the response message recording is performed, and step 126 is performed.
The stop address reading shown in step (1) and the data transmission tone address minus processing (step 127) are performed. This is done by truncating the last part of the recorded content of the message for about 200ms, and actually by changing the read stop address.The amount of change is the stop address about 200ms before the recorded content. To be Then, in step 128, the stop address is written.

If it is determined in step 111 that the response message data is not the response message data, and if it is determined in step 130 that the response message deletion data is the response message deletion data, the response message deletion process is performed as shown in step 131. It is determined in step 130 that the data is not the response message deletion data, and step 13
If it is determined in step 5 that the data is recording key data, step 136
Message recording processing is performed, tape recording start processing in step 137 is performed, and message recording is performed.

It is determined that it is not the recording key data in step 135, it is determined in step 140 that it is the stop key data, and step 1
If it is determined in step 41 that tape recording is in progress, step 14
In step 2, tape recording stop processing is performed, in step 143 data transmission sound tape rewinding processing is performed, tape rewinding is performed for approximately 200 ms, and time stamp recording processing, that is, recording is performed as shown in step 144. The time when was performed is recorded as a synthetic voice created by a voice synthesis IC. Step
If it is determined at 140 and 141 that neither the stop key data nor the tape recording is being performed, other data processing is performed as shown in step 150.

On the other hand, if the device in which the necessary information is stored is set to the answering machine answer mode and it is determined in step 101 that the call is being received, step 102 determines that the call is in answering machine, and as shown in step 104, Counting, that is, the number of incoming signals is counted. When it is determined in step 105 that the count number has exceeded the predetermined value, the incoming call response process is performed in step 106, and step 1
In 07, the answering process is performed.

When the answering machine is processed, the message to be played back is stopped about 200 ms before the end of recording, so that the control signal is not sent to the outside caller. Also, the message recorded on the tape is 200ms before the end time
Since the time information of the minutes is recorded by voice, that portion is not transmitted to the outside caller.

[Effects of the Invention] As described above, the present invention is provided with the specifying means for specifying the recorded content so as not to reproduce the unnecessary portion of the recorded content at the end of the recording, so that only the specified content is reproduced.
Since unnecessary information is not reproduced, there is an effect that the caller on the outside line does not feel uncomfortable.
