Abstract

PURPOSE:To transmit a message to other slave set without excess provision of a radio transmission/reception section on a master set by providing a recording and reproduction function on the master set and applying recording or reproduction control to the function with a call button of the slave set. CONSTITUTION:A telephone system is provided with a recording means recording a message sent from a slave set in response to a call button operation of the slave set 30 at a master set 1, a slave call means calling other slave set in response to the stop button of the slave set 30, and a reproduction means reproducing the message content recorded in response to the call button operation of the called salve set. Then when the call button of the slave set 30 is depressed, the master set 1 discriminates it as the message recording when the call button of the slave set 30 is depressed to record the message content sent from the slave set 30. When the recording is finished and the depression of the stop button of the slave set 30 is discriminated, the master set 1 calls the slave set 30 to send the message and when the depression of the call button of the called slave set 30 is confirmed, the master set 1 reproduces the recording content and transmits it to the called slave set 30. Thus, it is not required for excess provision of a radio transmission/reception section on the master set 1 and the message is transmitted to other slave set 30.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is directed to a base unit connected to a telephone line and a plurality of slave units connected to the base unit via a wireless line. This invention relates to a wireless telephone device that transmits messages to people.

[Prior Art] In recent years, wireless telephone devices have been used as cordless telephones that allow calls to be made at a location remote from the location where the telephone is installed. This consists of a base unit connected to a telephone line and a slave unit connected to the base unit via a wireless line.Since the base unit and slave units are connected wirelessly, it can be used anywhere. There is no restriction on the length of the cord, and there is a great deal of freedom in where the handset can be installed. It is also possible to have multiple handsets.

[Problems to be Solved by the Invention] However, such conventional devices are designed so that only one child device is used for each parent device, so both the parent device and the child device have one transmitter and one receiver. There are only groups. For this reason, if one handset is to transmit a message to another handset, it is essential to add a wireless transmitter/receiver to the base, which is uneconomical.

[Means for Solving the Problems] In order to solve such problems, the present invention has a system that uses a call button provided on a handset and a message sent from the handset in response to the operation of the call button of the handset. Recording method for recording on the machine (
step 112), and a handset calling means (step 127) that calls another handset in response to the operation of the off button of the handset.
128> and a playback means (step 1
19〉.

[Operation] When the call button of the slave unit is pressed, the master unit performs step 106.
, 120, it is determined that the message is recorded, and steps 110 to 1 are performed.
12, the contents of the message sent from the handset are recorded. When it is determined in step 105 that the recording has finished and the off button of the slave device has been pressed, the parent device proceeds to step 1.
27, 128 to call a handset to send a message, and the call button of the called handset is pressed in step 1.
If confirmed in step 06, the master device plays back the recorded content and transmits it to the called slave device in steps 117 to 119.

[Example] Figure 2 is a flowchart showing the operation of this invention,
Here, explanation will be given assuming that there are multiple handsets. Now, when a certain handset presses the call button provided exclusively for messages in order to send a message, in step 103 the handset number a is ''.
It is determined that the data set in IJ and received in step 104 is data received by the slave device a. Then, in step 105, it is determined that the data is not cut button data, and in step 106, it is determined that it is call button data. At first, since no message is recorded, step 114 determines that it is a message room, and as shown in step 120, processing is performed to wait for the other party's handset number.

When the handset that presses the call button next dials the handset number of the handset of the person to whom it wants to send a message, it is determined in step 104 that data has been received from handset A, and in step 105 it is determined that it is not the cut button, and the call button is not pressed. At step 106, it is determined that it is not a call button, and at step 107, it is determined that it is dial button data. Since the setting to wait for the number of the other handset is performed in step 120, step 108 determines to wait for the handset number, and when the received dialed number is determined to be a valid handset number in step 109, step 110 From then on, as shown in step 112, the processes of connecting the call bus/recording IC, transmitting recording start data, and starting recording to the recording IC are performed.

Therefore, the handset that wants to send a message records the contents of the message after listening to the recording start data in step 111.

Next, the flow performs steps 131 and 132 to access other slave devices, and if necessary, step 13
9, appropriate processing is performed, but this step is not the gist of this application, so its description will be omitted.

During this time, the message is being recorded, but when the permissible recording time ends, step 133 indicates that the recording time is up and 'f'l@
I. In step 134, processing for transmitting recording/playback IC stop sound data is performed, and in step 135, processing for releasing the call bus/recording IC is performed.

Since this time is not the time when playback processing is being performed, it is determined in step 136 that playback has not ended, and the recording end flag is turned on in step 13.

The user of the slave device that was recording can hear the end of recording by hearing the recording/playback stop sound in step 134. For this reason, if you press the off button on the slave unit, Step 1
At step 04, it is determined that data has been received from slave unit a, and step 105
It is determined that this is cut button data. Then, step 121 determines that the recording IC is not in self-recording/playback, and step 129 determines that the recording flag is present since the recording end flag in step 137 is set, so steps 130, 126, 127, and 128 clear the flag, stop the radio of handset a, control the radio of the called handset,
Performs various processes for transmitting incoming message data from the called handset. The called side handset message reception data in step 128 is data for conveying a message, such as message lamp lighting information or ring tone transmission for a message. The user knows that a message has arrived by the sound, and by the lighting of the message lamp, that he or she has been called for a message, so he or she presses the call button to answer. Therefore, step 104 is determined to be data reception from handset a (in this case, a is replaced with a+1 in step 131), step 105 is determined not to be cut button data, and step 106 is call button data. It is judged that. Since recording has already been performed, step 114 determines that the message is not empty, and since the message memory is not recorded by the called handset, step 115 determines that it is not in use, and since a message is being received, step 115 116 is determined to be receiving a message. For this reason, steps 117 to 119 of connecting the call bus and recording IC, transmitting playback start sound data, and starting playback to the recording IC are performed.

This allows the called cod receiver to hear the contents of the message. In the meantime, after the necessary processes for other slave devices are performed in steps 131 and 132, when the recording time (playback time) time-up is PI@ in step 133, the processing for sending the recording/playback stop sound data is performed in step 134. , in step 135, the call bus/recording IC
Release processing is performed. Then, in step 136, it is determined that the playback has ended, so the recorded contents are cleared as shown in step 138, and the entire series of processing ends.

Note that although the above embodiment has been described in the case of three or more handsets, when there are two handsets, inputting the partner handset number and related processing therefor become unnecessary.
