Abstract

PURPOSE:To eliminate an operation for calling an incorrect telephone (calling) repeatedly by outputting a number confirmation message when the telephone circuit of a transmission destination is interrupted. CONSTITUTION:When the incoming call of the transmission destination is confirmed, a signal processing part 1 outputs a CNG signal by operating a tone generator 6. The return of a CED signal from the transmission destination from which the incoming call is received is awaited for prescribed time. The signal processing part 1, in the case of detecting the interruption of the telephone circuit by detecting a dial tone with a tone detection circuit 7 or a polarity inversion signal with an NCU 4 while awaiting the return, judges that a called party receiving the incoming call responds by a telephone set. The number confirmation message is outputted by operating a print output part 10, which confirms whether or not an error is present on the number of the transmission destination from which the call is issued. The number confirmation message is printed out along with alarm output, and in addition to that, it may be displayed on an operation display part 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a countermeasure function for making a wrong call.

[0002]

2. Description of the Related Art When a manuscript is transmitted by a facsimile apparatus, a transmission destination is called, a CNG signal is output after the transmission destination arrives, and a CED signal is transmitted from the transmission side for a predetermined time thereafter.
Wait for the signal to come in, confirm the receipt,
Original data is transmitted according to a normal facsimile communication procedure.

However, when such a conventional facsimile apparatus is used to call a transmission destination and the transmission destination is a telephone, only the signal tone such as a CNG signal can be heard at the reception side. Since it is not there, the telephone line is disconnected on the way. However, for fax machines,
When a telephone number is mistakenly registered as a one-touch dial or a speed dial, such a wrong telephone call (calling) is repeatedly performed, resulting in a great annoyance to the call destination.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and prompts confirmation of a calling number when a calling party makes a call and a responding party is a telephone. It is an object of the present invention to provide a facsimile device that automatically outputs a message.

[0005]

DISCLOSURE OF THE INVENTION The present invention proposed to achieve the above object is to disconnect the telephone line or CED within a predetermined time after outputting a CNG signal after receiving a call from a destination. When a destination disconnects the telephone line, it outputs a number confirmation message that confirms the called destination number, and when a CED signal is received from the called destination, the Facsimile transmission is executed according to a facsimile communication procedure.

The number confirmation message output from such a facsimile device may be printed on a recording sheet or may be displayed on the display section.

[0007]

According to the present invention, the wrong telephone call by the facsimile machine is determined by confirming that the other party receiving the call in response to the call is not able to make a call and the telephone line is disconnected. After that, within a predetermined time after the CNG signal is output, the CED signal is not returned from the transmission destination, and it is determined by the fact that the telephone line is disconnected. Therefore, when the CED signal is received from the incoming destination, the facsimile transmission is performed in accordance with the normal facsimile communication procedure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the facsimile machine of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows the basic configuration of a facsimile machine A of the present invention. C
It has a signal processing unit composed of a PU, and the basic internal circuit configuration is the same as that of a conventional fax machine.

That is, 1 is a signal processing unit composed of a CPU, and 2 is a unit for modulating the image data read and scanned by the image reading / scanning unit 9 and also for demodulating the image data modulated and transmitted through the telephone line L. A modem, 6 is a tone generator for generating a protocol signal transmitted according to a facsimile communication procedure, 7 is a tone detection circuit for detecting a protocol signal transmitted according to the facsimile communication procedure, and 4 is a command from the signal processing unit 1. Accordingly, the telephone line L is switched by the call circuit 5 having the handset 5A and the modem 2, and the NCU 3 is input by an input key such as a numeric keypad and a display operation unit 8 including a display unit such as an LCD. Is an auto dialer that automatically calls the specified destination number, and 9 scans the original and scans it to convert image information into image data. That the image reading scanner, the 10 modems 2
A print output unit 11 prints out the image data demodulated by the method on a recording sheet, and a memory 11 temporarily stores data necessary for facsimile communication and registers data such as a destination number.

Steps 100 to 112 in FIG. 2 show a transmission procedure and a control procedure executed in the facsimile apparatus of the present invention. When the document is set on the image reading / scanning section 9 and the ten-key pad of the display / operation section 8 is operated, the signal processing section 1 operates the auto dialer 3 to automatically call the destination number. In response to such a call, when the incoming call of the destination is confirmed within a predetermined time, the signal processing unit 1 operates the tone generator 6, outputs a CNG signal according to the facsimile communication procedure, and receives the call for a predetermined time. Wait for the CED signal to be returned from the destination.

While waiting for the reception of the CED signal, the signal processing unit 1 disconnects the telephone line by detecting the dial tone by the tone detection circuit 7 or by detecting the polarity inversion signal by the NCU 4. If it is detected, the other party who received the call determines that it has responded with the telephone, operates the print output unit 10 and outputs a number confirmation message, which will be described later, to check whether the called destination number is correct. Ask for confirmation. The number confirmation message may be printed out together with the alarm output, or may be displayed on the operation display unit 8. However, after sending the CNG signal,
When the CED signal is not returned, an error message is output in the same manner as when there is no incoming call within a predetermined time.

When the CED signal is returned from the destination of the incoming call within a predetermined time after the output of the CNG signal, the signal processing section 1 stops the output of the CNG signal and receives the DIS signal. Also in this case, a predetermined waiting time is provided, and if the DIS signal is received during that time, the DCS signal is sent and the image data is sent, but if not, an error message is output. In the example, one-touch dial and speed dial are not used, but one-touch dial,
The present invention is particularly useful in such a case as it can be applied to the case of making a call using a speed dial.

FIG. 3 shows an example of a number confirmation message output when the other party responds with a telephone call. The destination number and the calling date are displayed, and a message prompting you to confirm the calling number is also output.

[0014]

As described above, according to the facsimile apparatus of the present invention, it is possible to easily determine whether or not the called party is a telephone, and if the called party is a telephone and the telephone line is disconnected. Since the number confirmation message is automatically output, the harmful effect of calling the wrong number can be prevented.
