The memory 308 described above stores the image information from the line buffer 301 and the R signal generating circuit 303 when the internal printing unit 200 prints without sending it to the transmission line, and when it outputs to the transmission line. The image information which is compressed by the encoder 304 and synthesized by the synthesis circuit 305 is stored (may be directly input to the MODEM 306 from the synthesis circuit 305 without passing through the memory 308), and demodulated by the MODEM 306 when received from the transmission line.

FIG. 3 shows a format sheet 400 having the above-mentioned print color command. The format sheet 400 has command information for printing records of a predetermined page in a predetermined color, and in the case of this embodiment, an information identification symbol 490 having red marks at regular intervals is provided on the upper edge. The first one is a red monochromatic image. In addition to this, the format sheet 400 has a destination column 43.
It has 0, a communication column 440, and a sender column 450.

The operation of the above arrangement will be described below. First, when the format sheet 400 is placed on the platen 101 and the start switch is turned on, the reading unit 102 moves on the rail member 103, the fluorescent sheet lamps 104 and 105 illuminate the format sheet 400, and the reflected light is a mirror. 106 to the first image sensor 109 via the lens 107,
The first image sensor 109 generates a B color image signal. On the other hand, the second image sensor 111 receives the reflected light of which the red color is absorbed through the cyan filter 110,
A mixed image signal of the colors R and R is generated.

These image signals are stored in the corresponding line buffers 301 and 302 over a predetermined number of lines. The R signal generation circuit 303 includes a line buffer 301,
And 302, the R color image signal is output by comparing the stored contents, and the B color image signal and the R color image signal are checked by the control unit 316. Here, the R color information identification symbol 490 is checked.
Is read.

At this time, when the control section 316 detects that there is an R color information identification symbol 490 on the upper side of the format sheet 400 based on the output of the R signal generating circuit 303, the B color image of the line buffer 301 is detected. The signal output is also output to the encoder 304 as an R color image signal. Therefore, the content of the format sheet 400 is output to the encoder 304 as R color monochromatic image information, and the encoder 304 compresses each R color image signal and outputs it to the synthesis circuit 305. The synthesizing circuit 305 synthesizes the two R color image signals and stores them in the memory 308.

When the reading of the format sheet 400 is completed in this way, then a normal original is read. Also in this case, as in the above-described operation, the reading unit 102 moves on the rail member 103, and the fluorescent lamps 104 and 105 illuminate the document. The reflected light from the document reaches the first image sensor 109 from the mirror 106 via the lens 107, and the first image sensor generates a B-color image signal. On the other hand, the second image sensor 11
1 receives the reflected light of which the red color has been absorbed through the cyan filter 110 and generates an image in which the B and R colors are mixed.

These image signals are stored in the corresponding line buffers 301 and 302 over a predetermined number of lines. The R signal generation circuit 303 includes a line buffer 301,
And 302, the image data of R color is output by comparing the stored contents, and these image signals of B color and R color are input to the encoder 304 via the control unit 316. The encoder 304 uses B
The color and R color image signals are respectively compressed and output to the synthesizing circuit 305. The synthesizing circuit 305 synthesizes the compressed B and R color image signals, and then the memory 308
To memorize.

Here, the operator inputs a command for transmitting the image signal. This input may be performed before the document reading operation. An image signal is read from the memory 308 based on this input, modulated by the MODEM 306, and
It is sent to the telephone line 600 via 07. The image signal is transmitted to the destination connected by the electronic exchange 500.

The receiving side performs a recording operation based on the image signal transmitted. The configuration of the receiving side is assumed to have the same configuration as the transmitting side, and therefore its operation will be described with reference to FIG.

When the receiving side receives a call via the electronic exchange 500, the NCU 307 connects to the transmitting side. Then, when the image signal is received, the MODEM 306
Demodulates this and stores the image information of the format sheet and the image information of the document in the memory 308. The image information stored in the memory 308 is separated into B color and R color by the separation circuit 309.
The B color image signal is separated into the colors and decoded by the decoder 309, and the B color image signal is input to the first shift register 311.
The R color image signal is input to the second shift register 313.

First and second shift registers 311,
When an image signal is input to each bit of 313, the first and second latch circuits 312 and 314 respectively latch,
The thermal heads 201 and 202 are caused to generate heat based on the timing of the enable signal. Here, the latch circuit 31
The timing at which the image signal is output from the final stage of 4 to the thermal head 202 is the thermal head 2 only for the time described later.
It is delayed from the timing of outputting the image signal to 01.

The recording paper registered at the timing of heat generation of the first thermal head 201 is supplied from the paper feed tray 10 to the nip portion of the pressure roll 203, and black printing is performed using the B color ink donor film 205. Is performed for each line. The recording paper is printed by the thermal head 201 while receiving a black print, and the thermal head 2
Go to 02. When the moving distance l of the recording paper between the thermal heads 201 and 202 and the speed of the recording paper are v, the second thermal head 202 is driven with a delay of 1 / v. If n lines are printed during this l / v delay time, the latch circuit 314 has n stages of latch circuits, and each time an enable signal corresponding to the printing of each line is output. The input stage is sequentially transferred to the output stage one by one, and after n enable signals are output from the latch circuit 314, the second thermal head 202 is driven. By this printing operation, the recording paper is printed according to the contents of the black and red originals. In this printing operation, the control unit 316 on the transmission side transmits the first sheet as an R color image signal to the reception side based on the information on the format sheet 400, so that the first sheet is automatically transmitted as described above. It becomes a red monochromatic image. Therefore, the destination, address, and other important information can be easily distinguished from other normal information, and there is no risk of missing important information.
