Abstract

PURPOSE:To make a notification when a transmission is not available due to the state of the other device by outputting a busy sound when a CED/busy sound detecting section does not detect the line connection signal sent back from a receiver after sending dials from a control section and detecting the busy sound transmitted from an exchange. CONSTITUTION:After dialing from a control section 4, a CED/busy sound detecting section 7 does not detect a line connection signal sent back from a receiver but detects the busy sound sent from an exchange, a control section 1 outputs the busy sound, sent from the exchange, from a monitor speaker 9, immediately notifying the communication of the other device to an operator who has finished a sending control by means of the busy sound. Accordingly, when the state of the other device inhibits the communication, the fact is notified smoothly so that a transmission original is prevented from being left on the device for a long time because an operator could not find it or the check message showing the transmission inhibition is prevented from being printed out wastefully.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine having a notification function when transmission is impossible due to the state of a partner machine.

[0002]

2. Description of the Related Art During facsimile transmission, when the transmission side completes a dialing operation from the operation section, if the receiving side is not connected to the line and is in an empty state, the line is connected through an exchange and the transmitting side is connected. After the call signal (CNG) and the line connection signal (CED) are transmitted / received between the receiving side and the receiving side, the transmission processing operation between them is executed thereafter according to a predetermined signal sequence.

On the other hand, when the receiving side is communicating or when the line is congested and the line cannot be connected to the other side, the transmitting side does not detect the line connection signal (CED) returned from the other side, and the line is transmitted from the exchange. A busy tone indicating that the line cannot be connected is detected. In this case, in the current facsimile apparatus, in consideration of the inconvenience of the operator repeatedly repeating the document setting and dialing operation, it is usual to mount an automatic redial function for repeatedly calling the dial destination every certain time. And with many models that have an automatic redial function, if you cannot communicate with the other device even after redialing a certain number of times, check "The other device is in use" or "Check the status of the other device." It is usually provided with a function of displaying or printing out a check message such as "please" to inform the operator that communication is impossible.

[0004]

In the above facsimile apparatus having the automatic redial function, if the operator sets the original and dials once, the transmission process is executed as soon as the line becomes available, even while the partner machine is communicating. Therefore, it can be said that it is generally useful for improving the efficiency of transmission work. However, focusing on the case where it is not possible to finally communicate with the other machine even after repeated redialing, it is said that it is not always a convenient function for smoothly performing the facsimile transmission work depending on the usage situation of the user. There are many difficult cases.

That is, when the communication with the other party cannot be finally made using the automatic redialing function, as described above, a check message indicating that communication is impossible is printed out afterwards. However, in that case, not only is the recording paper wastefully consumed for the print of the check message, but also the transmission originals that are left on the machine for a long time for redialing may cause other originals in the meantime. There is a problem that you cannot send. Therefore,
In the example of a facsimile machine installed in a department with a high frequency of transmission, a function is provided to notify the operator immediately when a dialing operation is performed and the line connection cannot be established when the partner machine is communicating. It would be convenient.

The present invention addresses the above-mentioned needs.
The present invention provides a facsimile device having a notification function in the case where transmission is impossible due to the state of the partner machine.

[0007]

In the facsimile apparatus according to the present invention, an operation unit and a CED for detecting a line connection signal or a busy tone are provided as means for achieving the above object.
・ After dialing from the busy tone detector and the operation unit, press C
When the ED / busy sound detection unit does not detect the line connection signal returned from the receiving side device and detects the busy sound sent from the exchange, the transmission control unit outputs the busy sound from the speaker. Is configured.

[0008]

In this facsimile device, the CED / busy tone detecting unit does not detect the line connection signal returned from the receiving side device and sends it from the exchange after dialing from the operating unit for operating the ten-key pad or the auto dial key. When the busy tone generated is detected, the transmission control unit causes the speaker to output the busy tone sent from the exchange. Therefore, if the other device is in communication and transmission is impossible, the operator can be notified immediately by the busy tone output from the speaker after the calling operation as in the case of a telephone call.

[0009]

EXAMPLES Examples of the present invention will be illustrated and described below.
FIG. 1 shows a block diagram of a facsimile apparatus according to the present invention. In the figure, reference numeral 1 denotes a control unit (CPU) that controls communication of the apparatus, and also serves as a transmission control unit according to the present invention.
The control unit 1 uses the telephone line L via the modem 2 and the NCU 3.
Connected to and necessary for sending and receiving facsimile,
It is configured to include an output device and the like.

That is, reference numeral 4 denotes an operation section including a ten-key pad, a one-touch dial key, etc., and when the operation section 4 is operated by a key during transmission, a telephone number entered by the ten-key operation or a telephone number storage section 5 designated by the one-touch dial key is displayed. The registered telephone number is output from the dial pulse generator 6 through the line L, and the dial transmission operation to the exchange is performed. In addition to the above, the operation unit 4 is provided with a communication start key, a stop key for stopping a busy sound output from a monitor speaker, which will be described later, and the like.

Reference numeral 7 is a CED / busy sound detecting unit for detecting a line connection signal (CED) or a busy tone, which is received when a line connection is established with the partner machine after dialing from the operation unit 4. The line connection signal of the specific frequency returned from the side device, or the busy tone of the specific frequency sent from the exchange when the line connection with the partner device is not performed, is detected and input to the control unit 1. ..

Reference numeral 9 denotes a monitor speaker for outputting a busy tone sent from the exchange after dialing.
The speaker controller 8 is connected to the line L via the speaker 3 and is output controlled by the controller 1.

In addition, in FIG. 1, 10 is a document reading unit for reading an image of a transmission document, 11 is a printer for outputting a received image, and 12 and 13 are ringing time during dial transmission and busy from the monitor speaker 9. The 1st, 2nd timer for setting up sound output time is shown.

In this facsimile apparatus, however, the operation unit 4 is operated at the time of transmission in accordance with the operation procedure of the transmission control program stored in advance in the storage unit (not shown) of the control unit 1.
When the CED / busy sound detection unit 7 does not detect the line connection signal returned from the receiving side device and detects the busy sound transmitted from the exchange after dialing from the dialing device, the busy sound is directly monitored by the monitor speaker. It is designed to output from 9 for a certain period of time.

FIG. 2 shows a flowchart of the processing operation executed by the present apparatus during transmission.

After the transmission original is set on the original reading unit 10, for example, the one-touch dial key of the operation unit 4 for instructing the auto dial is operated to turn on the start key (s).
1) Then, line L is DC closed (off-hook) (s2)
The designated telephone numbers registered in the telephone number storage unit 5 are sequentially transmitted from the dial pulse generation unit 6 to the line L (s3).
To be done. After that, the control unit 1 sets the calling time T1 for calling the partner machine in the first timer 12 (s4), and then determines whether or not the line connection signal (CED) from the receiving side device is returned (s5). Here, C from the receiving side
When ED is detected, thereafter, signal transmission / reception based on a prescribed prescribed signal sequence is performed, and F transmission / reception with respect to the partner device is performed.
The AX transmission process is executed (s6). After the transmission process, the transmission result is normally determined (s
7) If the result is OK, immediately, and if the result is NG, print a check message to that effect from the printer 11 as necessary (s8), and then open the DC (on-hook) and end the processing. become.

On the other hand, if CED is not detected in step s5, it is determined whether there is a busy tone sent from the exchange to the line L when the line connection is impossible (s9). Here, when the busy tone is detected, the control unit 1 first sets the second
After the time T2 for outputting the busy tone is set in the timer 13, the speaker control unit 8 is turned on and the busy tone sent to the line L is directly output from the monitor speaker 9. Therefore, the operator can immediately recognize that the partner machine is in communication by the busy tone (two-to-sound) notified from the speaker 9. The output of the busy tone from the speaker 9 is continued until the operator operates the stop key of the operation unit 4 or the timer set time T2 elapses (s12, s13), and then the speaker 9 is turned off.
After FF (s14), the line is disconnected (s16), and the process ends.

If the CED / busy sound detector 7 detects neither the line connection signal nor the busy tone in steps s5 and s9, it is considered to be a malfunction or line failure, and the timer set time T1 elapses ( After s15), the line is disconnected (s16) and the process ends.

As described above, in this facsimile apparatus,
When the CED / busy sound detector 7 does not detect the line connection signal returned from the receiving side device but detects the busy tone sent from the exchange after dialing from the operation unit 4, the control unit 1 The busy tone sent from the exchange is output from the monitor speaker 9, and the busy tone is used to immediately notify the operator who has completed the transmission operation that the partner machine is communicating. Therefore, when communication is not possible due to the state of the other machine, the operator does not know the fact as before, and the transmitted document is left on the machine for a long time without being known,
Check messages indicating that transmission is not possible are no longer printed out unnecessarily. For example, if you use another communication line or give priority to other originals, you can promptly send the message on a case-by-case basis. Can be dealt with.

In the case of following the flow of FIG. 2, when the CED / busy tone detection unit detects a busy tone after the dialing operation, the dialing of the other party is not performed in principle, but according to the present invention. It is also possible to combine the busy tone output function and the automatic redial function so that the busy tone is output each time the other device is in a call at the time of redialing. Further, the busy tone output function according to the present invention and the existing automatic redial function may be made optional by the user by switching the switch.

[0021]

As described above, in the facsimile apparatus according to the present invention, during transmission, when the other machine is communicating and the line cannot be connected, a busy tone is output from the speaker and the fact is immediately notified. Since the notification is made, the operator does not notice that the communication is impossible, and the problem that the transmission document is left on the machine for a long time is reliably avoided, and it is possible to deal with the situation flexibly. Further, when the automatic redial function is not used to finally communicate with the partner machine, it is possible to eliminate the waste of recording paper due to the printout of the check message output afterwards.
