Abstract

PURPOSE:To allow the other party of communication to know that a received original is a white paper by continuing a communication without cutting a line after the completion of the communication, and transmitting a message to the other party of communication when the received original is the white paper. CONSTITUTION:A second memory part 18 stores received fax data. A discriminating part 16 discriminates whether or not the white data ratio of the white data of the second memory part is beyond the prescribed white data ratio, and a printing part 17 prints the data when it is not beyond the prescribed white data ratio. When it is beyond the prescribed white data ratio, a DTMF signal is transmitted from a dial signal transmitting part 10 at the time of the completion of the transmission of the data from the other party, the other party is switched to a reception mode, and the message 'the white paper original is transmitted and please transmit again' stored in a second storage part 15 is transmitted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile device, and more particularly to a device for notifying a partner when a received document is blank.

[0002]

2. Description of the Related Art Conventionally, in facsimile communication, when a transmission original is set in a printing section, it is often mistakenly turned over to set the original. Since the operator does not know this, a blank document is transmitted to the transmission partner, and the facsimile machine on the receiving side prints the received data on a sheet, but a blank sheet is issued. Since the person who received the paper is blank, it cannot be known from whom it was sent, so there was a problem that it was not possible to take measures such as reminding the other party. In addition, it is often a problem to send blank data endlessly by a mischievous fax and empty the paper on the receiving side.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art. When the received original is a blank sheet, the communication is continued without disconnecting the line after the end of the communication and the communication is continued to the other party. The purpose is to notify by sending a message to that effect.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a facsimile unit for performing fax transmission and reception and a DTM for discriminating a received dial signal.
F (multi-frequency code) discriminating section, first memory section for storing the discriminated dial signal, first storing section for storing predetermined data, data stored in the first memory section and first storing section Comparing the data stored in the same and outputting a coincidence signal if they match, a display unit for displaying a message by the signal from the comparison unit, the facsimile device unit, DT
A first control unit for controlling the MF discrimination unit, the first memory unit, the first storage unit, the comparison unit and the display unit, a second memory unit for storing the received fax data, and a dial signal transmission unit for transmitting the DTMF signal. A second storage unit that stores predetermined data; and a determination unit that determines whether or not the ratio of the predetermined white data is exceeded from one page of the data in the second memory unit.
A second control unit that sends data to the other party by fax when the determination of the determination unit is exceeded, and issues a print command to the data of the second memory unit when the determination of the determination unit is not exceeded. , A printing unit for printing the data in the second memory unit.

[0005]

According to the above construction, the second memory section stores the received fax data. The determination unit determines whether or not the white data in the second memory unit exceeds a predetermined white data rate, and if not, the data is printed by the printing unit. If it exceeds the limit, when the transmission from the other party is completed, the DTMF signal is transmitted from the dial signal transmission section, the other side is switched to the reception mode, and the document data stored in the second storage section "A blank original has been transmitted. , Please resend "message.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing an embodiment of the facsimile apparatus of the present invention. In the figure, reference numeral 1 denotes a facsimile unit which transmits a document and receives a fax from a partner. Reference numeral 3 denotes a DTMF discriminating unit, which receives a dial signal transmitted from the other party by the facsimile unit 1 and discriminates it by the DTMF discriminating unit. A first memory unit 6 stores the discriminated dial signal. The first storage unit 2 stores predetermined data (for example, 111 #). 5 is a comparison unit, which is the first
The data (the dial signal transmitted from the other party) stored in the memory unit 6 is compared with the predetermined data stored in the first storage unit 2, and if they match, a coincidence signal is output. 20
Displays a message from the other party on the display. A first control unit 4 controls the facsimile device unit 1, the DTMF discrimination unit 3, the first memory unit 6, the first storage unit 2, the comparison unit 5, and the display unit 19. 8 is a facsimile transmission side. A line 7 connects the facsimile unit 1 and the network control unit 9 via a switch (not shown). A network control unit 9 has functions such as transmission of a selection signal, reception of a calling signal, and holding of a DC loop. 14 is a modem section,
It demodulates the received data and modulates the data to be transmitted.
A decompression unit 11 decompresses the received data from the modem unit 14. A compression unit 12 compresses transmission data. A second memory unit 18 stores the received fax data.
Reference numeral 15 denotes a second storage unit, which is predetermined data (a message to be sent to the other party "a blank original has been sent, please resend it")
I remember. A discrimination unit 16 discriminates whether or not one page of data in the second memory unit exceeds a predetermined white data rate. Reference numeral 10 is a dial signal transmission unit, which has a predetermined DT.
Sends the MF signal. Reference numeral 13 is a second control unit, which is a discriminating unit 16
When the determination is excessive, the data in the second storage unit is faxed to the other party, and when the determination in the determination unit 16 is not excessive, the data in the second memory unit 18 is instructed to print, and the network control device unit 9 and the modem are used. The unit 14, the decompression unit 11, the compression unit 12, the second memory unit 18, the second storage unit 15, and the dial signal transmission unit are controlled. A printing unit 17 prints the data in the second memory unit. Reference numeral 19 is a facsimile receiving side.

In the above structure, the facsimile unit 1
Set the original to be sent to and send by fax. The transmitted data is received by the facsimile reception side 19, demodulated by the modem unit 14, expanded by the expansion unit 11, and stored in the second memory unit 18. The stored data is binary data of white data and black data, and the discrimination unit 16 discriminates whether the ratio of white data to black data exceeds or does not exceed a predetermined value among these two values. For example, if the white data rate is set to 95%, it is considered that the rate of white data exceeds 95% if the original is mistakenly turned over and transmitted.
The determination unit 16 determines that one page of the data in the second memory unit is 95
If the judgment criterion of% is exceeded, that is, if a signal indicating the excess is output, the second control unit 13 causes the dial signal transmission unit 10 to switch from transmission to reception to the other party when the fax transmission from the other party is completed. In order to receive it, “111 #” and the data “blank document transmitted, please retransmit” stored in the second storage unit 15 are transmitted. The transmitted data “111 #” is discriminated by the DTMF discriminating unit 3 and the first
The determined dial signal of “111 #” is stored in the memory unit 6. The comparison unit 5 compares the data “111 #” stored in the first memory unit 6 with the predetermined data “111 #” stored in the first storage unit 2, and if they match each other, “a blank original has been transmitted. , Please resend ”message is displayed on the display unit 20. Instead of displaying the message on the display unit 20, the message may be printed on paper. If the discriminating unit 16 outputs a signal indicating that the number is not exceeded, the second control unit 13 causes the printing unit 17 to print the data stored in the second memory unit 18 on paper and output it.

[0008]

As described above, according to the present invention, when a blank original is sent, it is not printed on the paper and the message is continuously sent to the other party without disconnecting the line at the end of the transmission from the other party. Since a blank sheet is sent and the blank page is sent, the sender has the advantage of being aware of it and resending the correct original.
