Abstract

PURPOSE:To easily and quickly recognize the communications situation by permitting an extension network control unit to call the telephone set of a previously inputted extension number upon the completion of facsimile transmission and transmitting its communications situation (information on normal termination or on abnormal one) to the telephone set concerned. CONSTITUTION:When a transmitting party execute facsimile communications, he sets a transmission original on a facsimile equipment, and then inputs information necessary for facsimile transmission such as an opposite party's telephone number and a transmission mode through an operating part 7. If the transmitting party in a distance place wants to recognize the communications situation of the transmission through an extension telephone set, he inputs simultaneously the extension number through the operating part 7. After starting the communications, a relay 23 disconnects the connection between a MODEM 20 and an outside line NCU 21, and switches to the connection between the MODEM 20 and an extension NCU 22. Here the telephone line of the outside line (outside line telephone set) is disconnected from the MODEM 20, which is connected to the telephone line of the extension (extension telephone set).

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile device capable of transmitting information regarding normal or abnormal completion of facsimile transmission to a facsimile sender via an extension telephone.

2 Beno Prior Art Conventional facsimile machines use a means to notify the facsimile sender of information on the normal or abnormal end of facsimile transmission (hereinafter referred to as communication status) by stamping a completion stamp on the transmitted document when the facsimile transmission ends normally. In the case of stamping or abnormal termination, a method is adopted in which an alarm sound is generated and the abnormality is displayed on a display provided on the operation panel.

Therefore, the sender (including those involved), for example, waits next to the facsimile machine from the start of transmission until the end of transmission, and checks whether an alarm sound is generated or not. After the facsimile transmission is completed, the user goes to the location where the facsimile machine is installed and checks the communication status of the facsimile transmission by visually checking whether a completed stamp has been affixed to the transmitted document.

In other words, in the case of a conventional facsimile machine, if the facsimile machine is installed in a remote location, such as not on the same floor as the sender's permanent residence, the sender can check the communication status by: For example, the sender has to go to the location where the facsimile machine is installed, or has used an extension telephone to make an inquiry to someone in the vicinity of the location.

Problems to be Solved by the Invention As described above, in conventional facsimile machines, as a means of notifying the sender of the communication status of facsimile transmission, methods such as affixing a completed stamp, generating an alarm sound, or displaying an abnormality on the display are used. Therefore, if a sender who is located far from the facsimile machine's installation location wants to check the communication status of the facsimile transmission, he or she must go to the facsimile machine's installation location or go to a location near the installation location. There was a problem in that it required a person at the office to make an inquiry using an extension telephone, etc., which required time and manpower.

The present invention has been made in view of the above-mentioned circumstances, and allows even a sender who is located far away from the installation location of a facsimile machine to be able to send a facsimile according to the sender's request without requiring manpower or time unlike in the past. An object of the present invention is to provide a facsimile device that allows the communication status of facsimile transmission to be easily and quickly confirmed.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an extension network control device connected to an extension line (extension telephone), an external line network control device connected to an outside line (external telephone), a switching means for connecting either of these devices to the modem; an extension number input means for the extension telephone; a storage section for the extension number; A means for transmitting the communication status of the facsimile transmission by making a call through the telephone is provided, and after the transmission is completed, the sender at a remote location is notified of the communication status of the facsimile transmission via the extension telephone. be.

Effect of the present invention With the above-described configuration, the communication status of facsimile transmission is transmitted to the telephone with the extension number entered in advance after the transmission is completed, so that the communication status of facsimile transmission is transmitted to the telephone set with the extension number entered in advance. This makes it possible for senders to check the communication status easily and quickly, without requiring manpower or time as in the past.As a result, abnormal termination of transmission can be quickly dealt with, etc. There is also the effect of

FIG. 2 is a schematic block diagram showing an example of a specific configuration of the communication section 1 in FIG. A control device (hereinafter abbreviated as NCU), in this example,
21 is an NCU for outside lines, and 22 is an NCU for internal lines.

The outside line NCU 21 has a telephone line (communication line) for an outside line (external line telephone, etc.), and the extension NCU 22 has a telephone line (communication line) for an outside line (such as an outside line telephone).
The telephone lines (communication lines) of the extension telephones are connected to each other.

23 is NCU 21 for outside line and modem 20, or NC for extension line
This relay 23 is a switching relay (switching means) for switching the connection between U22 and modem 20.
Controlled by U4.

FIG. 3 is a flowchart for explaining the processing operation of the CPU 4 when transmitting the communication status of facsimile transmission (information on normal termination or abnormal termination) to the extension telephone.

The operation of the facsimile apparatus of the present invention will be described below with reference to FIGS. 1B to 3.

When a sender performs facsimile transmission, after setting a transmission document in the facsimile machine, the sender inputs information necessary for facsimile transmission, such as the recipient's telephone number and transmission mode, from the operation unit 7.

At that time, if the sender at a remote location wishes to check the communication status of the transmission using the extension telephone [YES in step 101 in Figure 3 (hereinafter abbreviated as ST)], A number is also input from the operation section 7 at the same time (ST102).

In addition, if the extension number is not input (STIOl NO.
), normal facsimile communication is carried out (STII
O).

As means for inputting the extension number from the operation section 7, there are, for example, a method of manually inputting it via an operation panel provided on the operation section 7, and other methods.

Further, the extension number input from the operation section 7 is stored in the RAM.
3 (ST102).

In this way, when the extension number is input from the operation unit 7 and all input operations necessary for facsimile transmission are completed, facsimile communication is started (ST103).

After the communication starts, if an error occurs for some reason (YES in ST104), or if no error occurs (ST104ONO) and the communication ends successfully (YES in ST105), the switch is switched under the control of the CPU 4. The relay 23 operates, and this relay 23 disconnects the modem 20 and the outside line NC'U 21, and switches the connection between the modem 20 and the extension line NCU 22 (ST1
06).

At this point, the telephone line of the outside line (external telephone, etc.) is disconnected from the modem 20, and the modem 20 is connected to the telephone line of the extension line (extension telephone).

Next, the CPU 4 retrieves the pre-input extension number from the RAM 3. Then, the extension NCU 22 calls the telephone of that extension number 5TI07) and transmits the facsimile transmission status to the extension telephone (ST108).

In this embodiment, the means for transmitting the communication status is the transmission of a tonal signal by the modem 20. That is, the frequency of the tonal signal to be transmitted at the time of normal termination and abnormal termination is set in advance, and this is transmitted after connecting to an extension telephone depending on the communication situation. Fig. 4 shows an example of this. At normal termination, an 800Hz tonal signal is continuously transmitted for 10 seconds to generate a normal termination sound, and at abnormal termination, 400H2 and 5OOHz tonal signals are transmitted for 0.5 seconds. The abnormal termination sound is generated by continuously transmitting a message for 10 seconds alternately every other time.

However, the present invention is not limited to this, and it goes without saying that various transmission means may be employed.

The normal end sound and the abnormal snoring sound allow the sender to easily and quickly check the communication status of facsimile transmission, even if the sender is away from the facsimile machine, as long as the sender has an extension telephone.

When the transmission of the communication status is completed, the CPU 4 operates the ten vane switching relay 23 again to disconnect the modem 20 and the extension NCU 22, and switch the connection between the modem 20 and the extension NCU 21 (ST109). As a result, the telephone line of the extension (extension telephone) is disconnected, and the telephone line of the outside line is restored to the so-called initial state (standby state) in which the telephone line is connected.

Effects of the Invention As is clear from the detailed description above, the present invention provides an extension network control device in addition to an external line network control device, and uses the extension network control device to input information in advance after facsimile transmission is completed. The system makes a call to the telephone with the specified extension number and transmits the communication status of the facsimile transmission (information on normal completion or abnormal termination) to that telephone. This has the advantage that the sender at the sender can simply and quickly confirm the normal or abnormal end of the facsimile transmission at his/her own request without requiring manpower or time as in the past.
