Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a telephone set composed of a master unit and a slave unit, and particularly gives priority to a bell (including a speaker) of the master unit or the slave unit when receiving a call. The present invention relates to a telephone to be activated (operated).

[Conventional technology]

Conventionally, this type of telephone is set up when an incoming call arrives based on a signal from operating a specified function key (master unit bell priority key or slave unit bell priority key) on the master unit operation unit of the master unit or the slave unit operation unit of the slave unit. Set the master bell priority mode to give priority to the bell of the master unit and ring the bell of the master unit and the slave unit at the same time a predetermined number of times, for example, 10 times, or give the bell of the slave unit a priority number of times For example, after ringing ten times, a slave unit bell priority mode is set in which the bells of the master unit and the slave unit ring simultaneously.

Therefore, the master unit bell priority mode or the slave unit bell priority mode can be selected by operating the master unit bell priority key or the slave unit bell priority key in consideration of the installation locations of the master unit and the slave unit.

[Problems to be Solved by the Invention]

Since the conventional telephone is configured as described above,
When an extension call is made between the base unit and the handset while the handset bell priority mode is set, data for ringing the handset bell is sent from the base unit to the handset. Therefore, the ringing instruction data for ringing the bell of the child device is converted into an audible signal, which is inconveniently emitted as noise along with the conversation from the handset of the child device.

Therefore, in order to prevent noise from being generated from the handset of the handset in this way, the extension call is automatically terminated if there is an incoming call while the extension call is being made between the base unit and the handset. After that, the bell of the handset is made to ring based on the handset bell priority mode.

However, since the extension call is forcibly ended, there is a disadvantage that the extension caller feels uncomfortable.

Furthermore, as described above, in order to prevent noise from being generated from the handset of the handset when a conversation is made, if the incoming call is ignored so as not to make the internal caller feel uncomfortable, the incoming call (caller) can be answered during the internal call. There was the inconvenience of disappearing.

The present invention has been made to solve the above-described inconvenience, and even if an extension call is made in a state in which the handset bell priority mode is set, noise is emitted from the handset of the handset along with the conversation. It is possible to provide a telephone that can prevent the call and can also answer the incoming call (caller).

[Means for solving the problem]

Means adopted by the present invention to solve the above-mentioned problems will be described.

In a telephone consisting of a base unit connected to an outside line and a handset connected to the base unit, when a call is received from the outside line, the bell of the base unit is given priority to ring or the bell of the handset is set to ring. Bell ringing setting means for setting whether to ring preferentially based on a setting signal from either the operation unit of the master unit or the operation unit of the slave unit, and an extension call state between the master unit and the slave unit. When an extension call is received by the extension call detecting means for detecting the extension call, the bell of the master unit is rung while the extension call state is detected by the extension call detecting means, and the extension call detecting means extends the extension line. Bell ringing switching means for switching to ring the bell of the master unit or the slave unit set in the bell ringing setting unit preferentially when the call state is not detected.

[Action]

The bell ringing setting means determines whether to give priority to ringing the bell of the master unit or ringing the bell of the slave unit when an incoming call comes in from the outside line, using either of the setting signals from the operating unit of the master unit or the slave unit. It is set based on.

The bell ringing switching unit rings the bell of the master unit when the extension call detection unit detects the extension call state when an incoming call is received on the outside line, and rings the bell when the extension call state is not detected. The bell of the master unit or the slave unit set in the setting means is switched so that it rings first.

As described above, when an incoming call is received from an outside line, it is set whether the bell of the base unit is given priority to ring or the bell of the handset is given priority, and the extension between the base unit and the handset is set. When a call is not being made, the bell of the set master unit or slave unit is given priority to ring, and during the extension call, the bell of the master unit is set to ring so that the bell of the slave unit has priority. Even if an incoming call is received during an extension call with the ring tone set to ring, the bell of the master unit does not ring and no noise is emitted from the handset of the slave unit.

Further, the ringing of the bell of the master unit is transmitted from the transmitter of the master unit to the receiver of the slave unit, and the slave unit can also know that there is an incoming call.

Further, when there is an incoming call after the call ends, the bell of the parent device or the child device that has been set previously rings with priority, so that it is not necessary to reset.

23 or a slave unit control unit 26 that controls the oscillator circuit 27, an oscillator circuit 27 that outputs an oscillation signal under the control of the slave unit control unit 26, and a slave unit that operates based on the oscillation signal of the oscillator circuit 27. It is composed of a speaker 28.

FIG. 2 is a flow chart for explaining the operation according to the present invention, and ST1 to ST8 show each step.

 Next, the operation will be described.

First, when the master unit bell priority key of the master unit operation unit 12 of the master unit 1 is operated, the master unit control unit 13 causes the first bell on / off control circuit 10 to perform a bell-on operation based on a signal of operating the master unit bell priority key. Because it outputs a signal, the cordless handset operation unit 25 of the cordless handset 21
When the master unit bell priority key is operated, the slave unit control unit 26 determines the slave unit transceiver circuit based on the signal of operating the master unit bell priority key.
Since the bell-on signal is supplied to the second bell-on / off control circuit 11 via the 23, the slave unit antenna 22, the master-unit antenna 6, and the master-unit transmitting / receiving circuit 5, the second bell-on / off control circuit 11 sends the bell-on signal. The master unit control unit 13 outputs the bell-on signal to the first bell-on / off control circuit 10, so that the master unit bell priority mode is set as described above.

Therefore, the base unit ringabell signal generation circuit 7 outputs a bell signal to the base unit speaker 8 and the incoming call detection circuit 9 based on the incoming call signals from the station line connection terminals 2A and 2B, and the base unit speaker 8 operates. Incoming call (caller) can be answered by off-hooking the base unit handset 4 to notify the incoming call.

However, for example, if the master device handset 4 is not off-hook even if the master device speaker 8 operates (sounds) 10 times, the master device control unit 13 causes the second bell on / off control circuit 11, the master device transmitting / receiving circuit 5, and the master device. Since a signal for simultaneously operating the child device speaker 28 of the child device 21 is transmitted to the child device 21 via the device antenna 6,
The slave transmission / reception circuit 23, which has received the signal for operating the slave speaker 28 via the slave antenna 22, outputs the signal to the slave controller 26.

Since the slave unit controller 26 supplied with the signal for operating the slave speaker 28 in this way operates the oscillation circuit 27,
The slave speaker 28 operates based on the oscillation signal from the oscillation circuit 27.

Therefore, the handset speaker 28 operates at the same time as the base unit speaker 8 to notify the incoming call. Therefore, the handset handset 4 or the handset handset 24 can be hooked off to respond to the call (caller). You can

When the slave unit bell priority key of the master unit operation unit 12 is operated, the master unit control unit 13 outputs a bell-off signal to the first bell on / off control circuit 10 based on the signal of operating the slave unit bell priority key. Therefore, or when the handset bell priority key of the handset operation unit 25 is operated, the handset control unit 26 causes the handset transmitter / receiver circuit 23, handset antenna 22, and base unit antenna based on the signal of operating the handset bell priority key. Since the bell-off signal is supplied to the second bell-on / off control circuit 11 via the master unit transceiver circuit 6 and the master-unit transmission / reception circuit 5, the second bell-on / off control circuit 11 outputs the bell-off signal to the master-unit control unit 13, Since the machine controller 13 outputs a bell-off signal to the first bell-on / off control circuit 10, the slave machine bell-priority mode is set as described above.

Therefore, based on the incoming call signals from the station line connection terminals 2A and 2B, the base unit ringabell signal generation circuit 7 causes the incoming call detection circuit 9
The master unit control unit 13 outputs a signal for operating the slave unit speaker 28 to the slave unit 21 via the second bell on / off control circuit 11, the master unit transmission / reception circuit 5, and the master unit antenna 6 because the bell signal is output to the slave unit 21. Since the transmission is performed, the slave transmission / reception circuit 23 that receives the signal for operating the slave speaker 28 via the slave antenna 22.
Outputs the signal to the handset controller 26.

Since the slave unit controller 26 supplied with the signal for operating the slave speaker 28 in this way operates the oscillation circuit 27,
Since the slave unit speaker 28 operates based on the oscillation signal from the oscillation circuit 27 to notify the incoming call, the slave unit handset 24 can be off-hooked to respond to the incoming call (caller).

However, for example, if the handset handset 24 is not off-hook even if the handset speaker 28 operates (sounds) ten times, the handset controller 13 outputs a bell-on signal to the first bell-on / off control circuit 10. Since the slave unit speaker 28 and the master unit speaker 8 operate at the same time to notify the incoming call, it is possible to respond to the incoming call (caller) by off-hooking the slave unit handset 24 or the master unit handset 4. .

Further, as described above, when the handset handset 4 is off-hook and the extension key of the handset operation unit 12 is operated in the state where the handset bell priority mode is set, the handset control unit 13 operates the extension key. A slave unit control unit via the second bell on / off control circuit 11, the master transmitter / receiver circuit 5, the master antenna 6, the slave antenna 22, and the slave transmitter / receiver circuit 23 based on the operated signal.
Since the extension call data is transmitted to 26, the handset controller 26 operates the oscillation circuit 27, and the handset speaker 28 operates.

Therefore, the off-hook of the handset transmitter / receiver 24 enables extension communication between the base unit 1 and the handset 21.

Similarly, by operating the extension key of the handset operation unit 25, extension communication can be performed between the handset 21 and the base unit 1.

Next, the operation according to the present invention, that is, the operation during the extension call in the handset bell priority mode will be described with reference to the flowchart of FIG.

First, the master unit control unit 13 determines whether there is an incoming signal (step ST1), waits for the incoming signal if there is no incoming signal, and releases the slave bell priority mode if there is an incoming signal. To set the master unit bell priority mode (step ST
2).

 At this time, the switching information is stored in the memory.

Therefore, the master unit speaker 8 operates to notify the incoming call, but since the extension call is in progress, the slave unit handset 24 can also hear that the master unit speaker 8 is operating.

After step ST2, it is determined whether the handset call key of the handset operation unit 25 has been operated (step ST3), and if the handset call key has been operated, the handset call mode is set (step ST3). ST4), for example, it is determined whether the on-hook key of the handset operation unit 25 has been operated, that is, whether the call has ended (step ST5).

Then, if the call is not ended in the determination in step ST5, the call is waited for to be ended, and when the call is ended,
Since the memory stores the switching information, the master unit bell priority mode is canceled and the slave unit bell priority mode is set (step ST6), and then the process proceeds to step ST1.

At this time, after setting the handset bell priority mode, the switching information in the memory is cleared.

If it is determined in step ST3 that the handset call key has not been operated, it is determined whether the handset call key of the handset operation unit 12 has been operated (step ST7). If the handset call key has been operated, , After setting the base unit call mode (step ST
8) Go to step ST5.

Further, if it is determined in step ST7 that the master unit call key is not operated, the process proceeds to step ST4.

As described above, according to this embodiment, the master unit controller 13
When an extension call is being made between the master unit 1 and the slave unit 21 while the slave unit bell priority mode is set, the master unit cancels the slave unit bell priority mode based on an incoming signal from the incoming call detection circuit 9 Since the machine bell priority mode is set, no noise is emitted from the handset of the handset 21 and the operation of the base unit speaker 8 can be confirmed from the handset 21 as well. ) Can be responded to.

Further, since the master unit control unit 13 releases the master unit bell priority mode and sets the slave unit bell priority mode after the call ends,
It automatically returns to the desired handset bell priority mode.

Also, when the master unit bell priority mode is set, the bell of the master unit is rung when an incoming call is received whether or not an extension call is being made as in the conventional case.

In addition, although the cordless phone has been described as an example in the above-described embodiment, a telephone in which the parent device and the child device are connected by one wire may be used.

Further, the telephone according to the present invention may be any one that includes a main telephone (master device) that receives an outside line and at least one subordinate telephone (slave device) to which the incoming call is transferred from the master device.

〔The invention's effect〕

As described above, the present invention has the following effects.

When the incoming call is received from the outside line, it is set whether the bell of the base unit is given priority to ring or the bell of the handset is given priority, and no extension call is made between the base unit and the handset. In this case, the bell of the master unit or the slave unit that has been set is given priority to ring, and during the extension call, the bell of the master unit is set to ring, so that the bell of the slave unit has priority to ring. Even if there is an incoming call during an extension call with the status set to, the bell of the master unit will not ring and noise will not be emitted from the handset of the slave unit.

Further, the ringing of the bell of the master unit is transmitted from the transmitter of the master unit to the receiver of the slave unit, and the slave unit can also know that there is an incoming call.

Further, when there is an incoming call after the call ends, the bell of the parent device or the child device that has been set previously rings with priority, so that it is not necessary to reset.
