DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device such as a facsimile device having, for example, a cordless handset and enabling an extension call between the base unit and the handset.

[0002]

2. Description of the Related Art In the case of a conventional facsimile apparatus having a handset, an extension call can be made between the base unit and the handset. In such a facsimile machine, generally,
By making the ringing pattern of the internal ringing call different from the ringing pattern of the external line incoming call, it is possible to distinguish between the external line incoming call and the internal line calling.

[0003]

In the facsimile apparatus as described above, if an external line is received from the base unit while the extension unit of the base unit is being called, the user using the handset of the base unit is called a bell. The ringing notices the incoming call to the outside line. For example, when the handset is on-hook and then off-hook to respond to the incoming call, the bell ringing of the extension call on the slave unit is cut off. However, the user of the slave unit does not know the reason why the bell sound of the extension call is cut off.

[0004] On the other hand, if an incoming call is received from an external device while the extension of the base unit is being called from the slave unit, the bell of the base unit being called is continuously ringing according to the ringing pattern of the extension call. Similarly, it is impossible to know the incoming call to the outside line, and similarly, the user of the slave unit that is calling the master unit for the inside line cannot know the incoming call to the outside line. Therefore, an incoming call to an external line while the extension of the master unit is being called from the slave unit is left unanswered. In addition, when the user of the base unit off-hooks the handset and responds to an extension call from the slave unit without noticing the incoming call to the outside line, a connection to an outside line occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and when an external call is received during an extension call between a master unit and a slave unit, the bell ringing pattern is changed to an extension call. By changing to a different pattern from the case of
Provided is a communication terminal device such as a facsimile device capable of promptly responding to an external line call without leaving the external line call unattended, and enabling determination of an external line call during an internal call. And

Means for detecting a call, and means for changing a bell ringing pattern of the slave unit to a different pattern from that for the extension call when an external line call is detected from the master unit during an extension call of the slave unit. And

[0007] The communication terminal device of the first invention changes the bell ringing pattern of the slave unit to a different pattern from the case of the extension call when detecting an incoming call to the outside line during the extension call from the master unit to the slave unit. As a result, the user of the slave unit can know that the extension call has been interrupted due to an incoming call to the outside line during the extension call.

A communication terminal device according to a second aspect of the present invention is a communication terminal device capable of making an extension call between a parent device and a child device, wherein a means for detecting an incoming call to an outside line during an extension call from the child device to the parent device. Means for changing the bell ringing pattern of the base unit to a different pattern from the case of the extension call when an incoming call to an outside line is detected during the extension call of the base unit from the slave unit.

[0009] The communication terminal device of the second invention, when detecting an incoming call to the outside line during the extension call from the slave unit to the master unit, changes the bell ringing pattern of the master unit to a pattern different from that for the extension call. As a result, the user of the base unit notices the incoming call on the outside line even when the extension is being called, and can quickly respond to the incoming call on the outside line, and does not leave the incoming call on the outside line.

A communication terminal device according to a third aspect of the present invention is a communication terminal device capable of making an extension call between a master unit and a slave unit, wherein a means for detecting an incoming call to an outside line during an extension call from the slave unit to the master unit. Means for starting a bell ringing of the slave unit when an incoming call to an outside line is detected while the extension of the master unit is being called from the slave unit.

[0011] The communication terminal device of the third invention, when detecting an incoming call to the outside line during the extension call from the slave unit to the master unit, starts the bell ringing of the slave unit. Thus, the user of the slave unit can determine that an outside line has been received during the extension call.

FIG. 1 is a block diagram showing the configuration of a facsimile apparatus according to the present invention. The base unit 1 of a cordless phone (CLP: Cord-Less Phone) receives radio waves from the handset 2 and outputs it to the apparatus body (hereinafter referred to as the “fax side”). Send to 2. In addition to the push-button dial, an extension key for calling the extension of the slave unit 2 is provided on the fax side.

In addition to the push-on button dial, the handset 2 has an extension key for calling the extension of the base unit 1 and an outside line key for calling or receiving an outside line. In addition to the microphone and the speaker, a speaker for notifying an extension call or an external call is provided on the back side thereof, and a bell is ringed in a ringing pattern of the extension call or a ringing pattern of an external call different from the pattern of the extension call. Ringing ringer generation circuit (not shown)
Is built-in.

The CLP I / F (Interface) 3 indicates that the extension has been called from the FAX to the CLP.
It has an I / F port such as ITCM2 that indicates that an extension has been called to AX, and controls the input and output of signals between the master unit 1 and the CPU 4 on the fax side. An NCU (Network Control Unit) 5 connects the facsimile machine to an external line and controls data to pass through the exchange.

The facsimile-side CPU 4 controls the operation of each section of the apparatus to control communication. For example, in the case of an extension call from the handset 2, the ringer generation circuit 11 is controlled to ring the bell in the ringing pattern of the extension call, and when an incoming call to the outside line is detected during the extension call of the base unit 1, the ringer is generated. The circuit 11 is controlled to change the ringing pattern of the incoming call to the outside line, ring the bell, and determine whether the extension call is from the handset 2 or from the fax side, and whether the outside line call during the extension call is in the handset 2 The on / off control of the analog switch of the signal switching circuit 12 is controlled according to whether it is on the fax side or the like.

The monitor speaker 10 on the FAX side outputs a bell sound generated by the ringer generation circuit 11 when an extension is called from the slave unit 2 or when an external call is received. Ringer generation circuit 11
Is controlled by the CPU 4 to ring the bell in a ringing pattern for an extension call or a ringing pattern for an incoming call which is different from the extension calling pattern.

The signal switching circuit 12 generates an audio signal from the base unit 1 or the handset 13 on the fax side to the outside line to the NCU 5, an audio signal from an external line to the base unit 1 or the handset 13, and the ringer generation circuit 11 It is composed of various analog switches for passing the bell sound to the monitor speaker 10 and the like, and its on / off is controlled by the CPU 4.

Next, the operation of the facsimile apparatus according to the present invention will be described with reference to the flowcharts of FIGS. First, the operation at the time of calling an extension from the master unit to the slave unit will be described with reference to FIGS. When the extension key on the fax side is turned on (step S1), the CPU 4 switches the analog switch of the signal switching circuit to a state where an extension call can be made from the base unit 1 to the handset 2 (step S2). F3 I /
Turn on the F port ITCM1 (step S3).

When the I / F port ITCM1 is turned on, the PCB (Process Control Block) of the CLP master 1
It recognizes that it is an extension call (step S4), and notifies the cordless slave unit 2 that it is an extension call (step S5). Slave unit 2 that received notification of extension call from master unit 1
Sounds the bell in the ringing pattern of the extension call (step S6).

While the slave unit 2 is calling the extension, the CPU 4
Monitors the presence or absence of an incoming call to the outside line and whether or not the extension key of the slave unit 2 is turned on (steps S7 and S8), and when the extension key of the slave unit 2 is pressed, the master unit 1 The extension call to 2 is enabled (step S9). On the other hand, if an incoming call to an outside line is detected while the extension of the handset 2 is being called (step S7), the CPU
Controls the ringer generation circuit 11 to ring the bell on the fax side in accordance with the ringing pattern of an incoming call (step S10).

The CPU 4 notifies the base unit 1 of the incoming call (step S11), and instructs the slave unit 2 to change the bell ringing pattern via the base unit 1 (step S12). The handset 2 instructed to change the bell ringing pattern changes the ringing pattern of the extension call to the ringing pattern of the incoming call, and rings the bell (step S13).

While ringing the bells of the base unit 1 and the handset 2 in the ringing pattern of the incoming call to the outside line, the CPU 4 determines whether or not the outside line key of the handset 2 has been turned on, and the handset 13 on the FAX side temporarily goes on-hook. Then, it is monitored whether or not the off-hook operation has been performed again (steps S14 and S18). If the external line key of the slave unit 2 is turned on, the bell ringing of the slave unit 2 is stopped (step S15), and the bell on the fax side is stopped. The ringing is also stopped (step S16), and outside line communication with the slave unit 2 is enabled (step S16).
S17).

On the other hand, if the handset 13 on the fax side is once on-hook and off-hook again while the bells of the base unit 1 and the handset 2 are ringing in the ringing pattern of the incoming call to the outside line, the CPU 4 The bell ringing is stopped (step S19), and the bell ringing of the slave unit 2 is also stopped (step S2).
0), external telephone conversation with the handset 13 on the fax side is enabled (step S17).

Next, the operation at the time of calling an extension from the slave unit to the master unit will be described with reference to FIGS. When the extension key of the slave unit 2 is turned on (step S21), the ON information of the extension key is transmitted from the slave unit 2 to the PCB of the CLP master unit 1 (step S22). CPU 4 is the I / F port of CLP I / F 3
ITCM2 is turned on (step S23), and the analog switch of the signal switching circuit 12 is switched to a state in which an extension call from the slave unit 2 to the master unit 1 is possible (step S24). The CPU 4 controls the ringer generation circuit 11 to ring the bell on the fax side in accordance with the ringing pattern of the extension call (step S25).

While the bell on the fax side is ringing in the ringing pattern of the extension call, the CPU 4 monitors whether there is an incoming call on the outside line and whether the handset 13 on the fax side is off-hook (steps S26 and S27). . If the handset 13 on the fax side is off-hook (step S27), the CPU 4 enables an extension call from the slave unit 2 to the master unit 1 (step S28).
).

When an incoming call to an outside line is detected while the bell on the FAX side is ringing according to the ringing pattern of the extension call (step
In step S26), the CPU 4 changes the ringing pattern of the fax from the internal call to the external call pattern (step S29). Subsequently, the bell ringing of the slave unit 2 is started in the pattern of an incoming call to an outside line (step S30).

While the bell on the FAX side and the bell on the handset 2 are ringing in the ringing pattern for an external call, the CPU 4 determines whether the handset 13 on the FAX side is off-hook and determines whether the outside line key of the handset 2 is on. Monitor whether or not is turned on (step S31)
If the handset 13 is hooked off-hook (step S31), the bell ringing of the fax side is stopped (step S33), and the bell ringing of the slave unit 2 is also stopped (step S34). External telephone call is enabled (step S35). Similarly, when the external line key of the handset 2 is turned on (step S32), the bell ringing of the fax side is stopped (step S33), and the bell sounding of the handset 2 is also stopped (step S34). External line communication is enabled in step 2 (step S35).
