CONSTITUTION:When operating the bell priority key of operating section 12 of telephone set 1, a master telephone set control section 13 outputs a bell-on signal to a bell-off control circuit 10, so that a slave telephone control section 26 supplies the second bell-off control circuit 11 with a bell-on signal based on the signal that operated the master telephone bell priority key via a slave telephone sending/receiving circuit 23, slave telephone antenna 22, master telephone antenna 6, and master telephone sending/receiving circuit 5. The second bell-off control circuit 11 outputs a bell-on signal to the master telephone control section 13, the master telephone control section 13 outputs a bell-on signal to a bell-off control circuit 10, so that as aforementioned the telephone system is set into a master bell priority mode. With this, even when a call is received during the execution of a call between the extension lines, a noise can be protected from being generated from the receiver of the slave telephone set.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a telephone consisting of a base unit and a slave unit, and in particular, when a call is received, the bell (including the speaker) of the base unit or the slave unit is activated.
This relates to a telephone that gives priority to ringing (operation).

[Conventional technology]

Conventionally, this type of telephone has been designed to respond when an incoming call is received based on a signal obtained by operating a predetermined function key (base unit bell priority key or handset bell priority key) on the base unit operation unit of the base unit or the handset unit operation unit of the slave unit. After giving priority to the main unit's bell and ringing it a predetermined number of times, for example 10 times, you can set the main unit bell priority mode that rings the main unit and slave unit's bells at the same time, or give priority to the slave unit's bell. After ringing a predetermined number of times, for example 10 times, a slave unit bell priority mode is set in which the bells of the base unit and slave unit ring simultaneously.

Therefore, by operating the parent device bell priority key or the child device bell priority key in consideration of the installation locations of the parent device and the child device, it is possible to select the parent device bell priority mode or the child device bell priority mode.

[Problem to be solved by the invention]

Conventional telephones are configured as described above, so if a call comes in while the base unit and handset are having an internal call with handset bell priority mode set, the handset's bell priority mode is set. Since the data for ringing the bell is transmitted from the base unit to the handset, the ringing instruction data for ringing the bell of the handset is converted into an audible signal, which is inconveniently emitted as noise from the handset of the handset along with the conversation. Ta.

Therefore, in order to prevent noise from being emitted from the handset of the handset along with the conversation, if an incoming call is received while an extension call is being made between the base unit and the handset, the extension call is automatically terminated. After that, the bell of the handset is set to ring based on the handset bell priority mode.

However, since the extension call is forcibly terminated, there is an inconvenience in that the extension caller feels uncomfortable.

Furthermore, as mentioned above, in order to prevent noise from being emitted from the handset of the handset along with conversations, if you ignore the incoming call so as not to make the extension caller feel uncomfortable, the incoming call (caller) will not be able to answer the extension call. There was an inconvenience that it happened.

This invention was made to solve the above-mentioned inconvenience, and even when an extension call is being made with the handset's bell priority mode set, noise is emitted from the handset of the handset along with the conversation. The purpose of the present invention is to provide a telephone set that can prevent such calls from occurring and also respond to incoming calls (callers).

[Means to solve the problem]

The telephone according to the present invention includes an extension call detection means for detecting an extension call between the base unit and the handset, a mode determination means for determining the selected mode of the mode selection means, and an extension call detection means outputting an extension call signal, Mode switching means is provided for operating the mode selection means based on the incoming call signal from the incoming call detection means to select the main unit bell priority mode while the mode determining means is outputting the handset bell priority mode signal. It is something.

Further, the telephone according to another invention includes a switching information storage means for storing switching information indicating that the mode selection means has selected the base unit bell priority mode based on the output of the mode switching means, and a switching information storage means for storing switching information for selecting the main unit bell priority mode based on the output of the mode switching means; end detection means, and when the call end detection means outputs a call end signal and the switching information storage means stores switching information, after operating the mode selection means to select the handset bell priority mode, The present invention further includes second mode switching means for erasing switching information from the switching information storage means.

[Function] The telephone according to the present invention cancels the handset bell priority mode when an incoming call is received while the base unit and handset are having an extension call with the handset bell priority mode set. Set the main unit bell priority mode and operate (ring) the main unit's bell.

Then, after the call ends, the main unit bell priority mode is canceled and the slave unit bell priority mode is set.

Therefore, if you receive an incoming call while making an extension call with handset bell priority mode set, the base unit's bell will ring, and no noise will be emitted from the handset of the handset.
Since the ringing of the bell of the base unit can also be heard from the slave unit, the incoming call (caller) can be answered from the base unit or the slave unit.

It consists of

FIG. 2 is a flowchart for explaining the operation according to the present invention, and STI to ST8 indicate each step.

Next, the operation will be explained.

First, when the base unit bell priority key of the base unit operation unit 12 of the base unit 1 is operated, the base unit control unit 13 turns the bell on/off control circuit 10 to the first bell on/off control circuit 10 based on the signal from the operation of the base unit bell priority key. To output a signal, or when the base unit bell priority key of the slave unit operation unit 24 of the slave unit 21 is operated, the slave unit control unit 26 controls the slave unit transmitting and receiving circuit 23, based on the signal from the operation of the base unit bell priority key. The second bell-on/off control circuit 11 supplies the bell-on signal to the second bell-on/off control circuit 11 via the slave antenna 22, the base antenna 6, and the base transmitting/receiving circuit 5. Control part 1
3, and the main unit control unit 13 outputs a bell-on signal to the first bell-on/off control circuit 10, so that the main unit bell priority mode is established as described above.

Therefore, based on the incoming call signal from the office line connection terminals 2A and 2B, the base phone ringer signal generation circuit 7 outputs a bell signal to the base unit speaker 8 and the incoming call detection circuit 9.
The base unit speaker 8 operates to notify the incoming call, so the base unit handset 4 is off-hook to receive a call (calling party).
be able to respond to

However, if the base unit handset 4 is not off-hook even if the base unit speaker 8 operates (sounds) 10 times, the base unit control unit 13 controls the second bell-on/off control circuit 11, the base unit transceiver circuit 5, and the base unit transmitter/receiver circuit 5. Since a signal for simultaneously operating the handset speaker 28 of the handset 21 is transmitted to the handset 21 via the handset antenna 6, the handset transceiver circuit receives the signal to operate the handset speaker 28 via the handset antenna 22. 23 outputs the signal to the slave device control section 26.

The handset controller 26 to which the signal for operating the handset speaker 28 is thus supplied operates the oscillation circuit 27, so the handset speaker 28 operates based on the oscillation signal from the oscillation circuit 27.

Therefore, since the handset speaker 28 operates simultaneously with the base speaker 8 and notifies the incoming call, by off-hooking the base handset 4 or handset 24, the incoming call (
callers).

Furthermore, when the slave unit bell priority key of the base unit operating unit 12 is operated, the base unit control unit 13 outputs a bell-on signal to the first bell on/off control circuit 10 based on the signal from the operation of the slave unit bell priority key. Therefore, when the handset unit control unit 26 operates the handset bell priority key of the handset operation unit 24, the handset control unit 26 controls the handset transmitting/receiving circuit 23, handset antenna 22, and base unit antenna based on the signal from the handset bell priority key operation. In order to supply a bell-on signal to the second bell-on/off control circuit 11 via the main unit transmitting/receiving circuit 5 and the main unit transmitting/receiving circuit 5, the second bell-on/off control circuit 1 outputs the bell-on signal to the main unit control unit 13, Since the base unit control unit 13 outputs a bell-on signal to the first bell-on/off control circuit 10, the slave unit enters the bell priority mode as described above.

Therefore, the base unit ring bell signal generation circuit 7 outputs a bell signal to the incoming call detection circuit 9 based on the incoming call signal from the office line connection terminals 2A and 2B, so the base unit control unit 13 performs the second bell on/off control. Since a signal for operating the handset speaker 28 is transmitted to the handset 21 via the circuit 11, the base transmitting/receiving circuit 5, and the base antenna 6, the signal for operating the handset speaker 28 is received via the handset antenna 22. The handset transceiver circuit 23 outputs the signal to the handset controller 26.

The handset control unit 26, which is supplied with the signal for operating the handset speaker 28 in this way, operates the oscillation circuit 27, so the handset speaker 28 operates based on the oscillation signal from the oscillation circuit 27 and receives a call. handset 2 to notify
The incoming call (caller) can be answered by going off-hook.

However, for example, the handset speaker 28 operates (sounds) 10 times.
However, if the handset handset 24 is not off-hook, the base unit control unit 13 outputs a bell-on signal to the first bell-on/off control circuit 10, so the handset speaker 28 and the base speaker 8 operate simultaneously. In order to notify the incoming call, the handset handset 24 or the base handset 4 can be taken off-hook to respond to the incoming call (caller).

Furthermore, as described above, when the base unit handset 4 is off-hook and the extension key of the base unit operating unit 12 is operated while the handset is set to the handset bell priority mode, the base unit control unit 13 operates the extension key. Based on the operated signal, the second bell-on/off control circuit 11, the main unit transmitting/receiving circuit 5, the main unit antenna 6,
Since the extension call data is transmitted to the handset controller 26 via the handset antenna 22 and handset transmitter/receiver circuit 23, the handset controller 26 operates the oscillation circuit 27, so that the handset speaker 28 operates.

Therefore, by taking the handset handset 24 off-hook, the base unit 1 and the handset 21 can make an extension call.

Similarly, by operating the extension key on the handset operating section 25, an extension call can be made between the handset 21 and the base unit l.

Next, the operation according to the present invention, ie, the operation during an extension call in handset bell priority mode, will be explained based on the flowchart of FIG.

First, the base unit control unit 13 determines whether there is an incoming signal (step 5T1), and if there is no incoming signal, it waits for an incoming signal, and if there is an incoming signal, it cancels the handset bell priority mode. Set the main unit bell priority mode (step 5T)
2).

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

Therefore, the base unit speaker 8 operates to notify the incoming call, but since the extension call is in progress, the handset handset 24 can also hear that the base 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 5T3), and if the handset call key has been operated, the handset call mode is set (step 5T4). ), it is determined whether, for example, the on-hook key of the handset operation unit 25 has been operated, that is, whether the call has ended (step 5T5).

If it is determined in step ST5 that the call has not ended, the system waits for the call to end, and when the call ends,
Since the memory stores the switching information, after canceling the main unit bell priority mode and setting the slave unit bell priority mode (step 5T6), the process advances to step STI.

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

In addition, if the handset call key is not operated in step ST3, it is determined whether the base unit call key of the base unit operation section 12 is operated (step 5T7), and if the base unit call key is not operated. For example, after setting the base phone call mode (step 5T8), the process proceeds to step ST5.

Further, if it is determined in step ST7 that the base phone call key is not operated, the process advances to step ST4.

As described above, according to this embodiment, the base unit control unit 13
When the base unit 1 and the handset 21 are making an extension call with the handset bell priority mode set, the incoming call detection circuit 9
Since the handset bell priority mode is canceled and the base phone bell priority mode is set based on the incoming signal from the handset 21, no noise is emitted from the handset of the handset 21, and the operation of the base speaker 8 can be controlled from the handset 21. Since this can be confirmed, the incoming call (caller) can be answered from the base unit 1 or handset 21.

Furthermore, after the end of the call, the base unit control unit 13 cancels the base-machine bell priority mode and sets the handset bell priority mode, so that the desired handset bell priority mode is automatically restored.

In the above-described embodiments, a cordless phone has been described as an example, but a telephone in which a base unit and a slave unit are connected by a single wire may also be used.

Furthermore, although an example has been described in which the mode is returned to the handset bell priority mode at the end of a call, the main device bell priority mode may remain at the end of the call.

Further, the telephone according to the present invention may include a main telephone (base unit) that receives outside calls, and at least one slave telephone (slave unit) to which incoming calls are transferred from the base unit.

〔Effect of the invention〕

As described above, according to the present invention, when an incoming call is received while the base unit and the handset are having an extension call with the handset bell priority mode set, the handset bell priority mode is canceled. Since the main unit bell priority mode is set and the main unit's bell is activated, even if a call arrives during an extension call, no noise will be emitted from the handset of the handset.

Since the operation of the bell of the base unit can also be confirmed from the slave unit, there is an effect that an incoming call (caller) can be answered from the base unit or the slave unit.

Furthermore, since the main unit bell priority mode is canceled and the slave unit bell priority mode is set after the end of the call, there is an effect that the desired slave unit bell priority mode is automatically returned.
