The present invention is characterized in that it has an addition mode reception control means for outputting.

Therefore, in the present invention, when transmitting information written in the same format on multiple sheets, the format information is transmitted on the first sheet, and only the information written on the format on the second and subsequent sheets is transmitted. , 1 on the receiving side
Since the first image and the second and subsequent images are added together and output,
Transmission time can be shortened and communication costs can be reduced. Therefore, the time occupied by the transceiver is reduced and the device can be used more effectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

First, prior to a detailed explanation of this embodiment,
An overview of the processing in this device will be explained.

In this embodiment, when transmitting a plurality of sheets of information written in a fixed format, the sending side transmits the fixed form information to the first sheet, and this is stored on the receiving side. Also,
For the second and subsequent sheets, fluctuation information is transmitted, and on the receiving side, the fixed form information and the fluctuation information for the second and subsequent sheets are added and output.

Note that such a function is called addition mode transmission on the transmitting side, and addition mode reception on the receiving side.

When selecting the addition mode transmission using the transmitter, the information processing button 32 is pressed and the information processing lamp 34 is turned on. Then, on the first sheet, set the manuscript of fixed form information to be added and output in common, such as format,
From the second page onwards, set manuscripts containing variation information to be written in the format. Then, a call is made to the other party's device and communication begins.

[0013] At this point, it is checked in the previous step whether or not the other party's machine has the addition mode receiving function, and if the other party's machine does not have the addition mode receiving function, an alarm is sounded and the message "The other party's machine is It does not have an addition mode reception function. It outputs the report 03-123-4567XX Shoji.

[0014] Furthermore, if the other party's machine has an addition mode reception function, in the previous step, the other party is notified that communication will be performed using the addition mode reception function, and the set original is sent to the other machine. Transmit sequentially.

[0015] The receiver stores the first page of information in its memory, and adds the second and subsequent received information to the first page of information stored in the memory and outputs the resultant information.

[0016] Also, in the transmitter, the information processing lamp 3
If 4 is not lit, the addition mode transmission function declares in the previous step that no transmission will be performed, and normal transmission is performed.

Furthermore, when the receiver receives a declaration from the transmitter that the addition mode transmission function will not be used, it performs normal reception in which the received information is sequentially output as is.

Each element will be explained in order below based on FIG.

[0019] The NCU (network control unit) 2 connects to the terminal of the telephone network in order to use the telephone network for data communication, etc.
It controls connections to telephone exchange networks, switches to data communication paths, and maintains loops. The NCU 2 also controls the signal level (
If the signal line 36a) is "0", the telephone line 2a is connected to the telephone 4 side, and if the signal level is "1", the telephone line 2a is connected to the facsimile machine side. Under normal conditions, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates the transmission system signal and the reception system signal, and adds the transmission signal (
The signal line 16a) is sent to the telephone line 2a via the NCU 2, and the signal from the other party is sent to the NCU 2 and the hybrid circuit 6 (
V29 demodulator 20, V21 demodulator 1 via signal line 6a)
8.

The reading circuit 10 sequentially reads image signals for one line in the main scanning direction from a transmission original, and creates a signal string representing binary values of white and black, and is used for imaging with a CCD (charge coupled device) or the like. It consists of an element and an optical system. A binary signal string of white and black is sent from the signal line 10a to the encoding circuit 1.
Sent to 2.

The encoding circuit 12 encodes the read data (
MH (Modified Huffman) encoding or MR (Modified Read) encoding) and output to the signal line 12a.

The V27ter or V29 modulator 14 modulates the encoded output output from the signal line 12a of the encoding circuit 12 based on the known CCITT recommendations V27ter (differential phase modulation) or V29 (quadrature modulation). This is a modulator that performs The modulated output of this modulator 14 is sent to an adder circuit 16 through a signal line 14a.

The V21 modulator 8 is a modulator that performs modulation based on the well-known CCITT recommendation V21, and modulates the procedure signal (signal line 36b) from the control circuit 36 and sends it to the adder circuit 16 through the signal line 8a. It is something to do.

Addition circuit 16 is a circuit that adds the outputs of modulators 8 and 14. The output of the adder circuit 16 is sent to the hybrid circuit 6.

The V21 demodulator 18 performs demodulation based on the well-known CCITT recommendation V21. This demodulator 18 inputs the procedure signal from the hybrid circuit 6 through the signal line 6a, performs V21 demodulation, and sends the demodulated data to the control circuit 36 through the signal line 18a.

The V27ter or V29 demodulator 20 performs demodulation based on the well-known CCITT recommendations V27ter or V29. This demodulator 20 is
The modulated image signal from the hybrid circuit 6 is input, demodulated, and the demodulated data is sent to the decoding circuit 22 via the signal line 20a.
and sent to the memory circuit 24.

The decoding circuit 22 inputs the demodulated data from the demodulator 20, decodes it (MH decoding or MR decoding), and sends the decoded data to the adder circuit 28 via the signal line 22a.
This is what is output to. Note that the decoding circuit 22 does not perform any operation when a signal level "1" is output from the control circuit 36 to the signal line 36c.

The memory circuit 24 stores demodulated data from the demodulator 20 and outputs it to the decoding circuit 26 via a signal line 24a. The operation of this memory circuit 24 is controlled by a signal line 36d of a control circuit 36.
If the signal level of d is "0", no operation occurs; if the signal level is "1", demodulated data from the demodulator 20 is input and stored; if the signal level is "2", The stored data is output to the decoding circuit 26.

The decoding circuit 26 inputs the demodulated data from the memory circuit 24 and performs decoding (MH decoding or MR decoding).
decoding) and outputs the decoded data to the adder circuit 28 from the signal line 26a.

Note that the output operations of the decoding circuit 22 and the decoding circuit 26 are synchronized by a common clock.

The adder circuit 28 includes each of the decoding circuits 22,
The outputs of 26 are added together and outputted to the recording circuit 30 via the signal line 28a. Note that when the operation of the memory circuit 24 is stopped, only the output of one of the decoding circuits 22 is output to the recording circuit 30.

The recording circuit 30 sequentially records the decoded white and black signals output from the adding circuit 28 line by line. Furthermore, when a pulse is output to the signal line 36e from the control circuit 36, the recording circuit 30 receives, for example, the above-mentioned message "The other party's device does not have the addition mode reception function." 03-
123-4567XX Shoji” is output.

The information processing button 32 is a button that is pressed when selecting the addition mode transmission. When this information processing button 32 is pressed, a selection pulse is output to the control circuit 36 via the signal line 32a.

The information processing lamp 34 is connected to the information processing button 3
