It includes a histogram processing unit 70b and an error diffusion processing unit 70c.

The image data input section 70 is the CCD 42 shown in FIG.
Image data of the original read from
While taking a histogram as a binary digital amount, the image data is processed by the error diffusion method and temporarily stored in the memory 73.

That is, in the CCD section 70a, after the analog electric signal corresponding to each pixel density of the image data is A / D converted, MTF correction, black and white correction or gamma correction is performed, and 256 gradations (8 (Bit) digital signal is output to the histogram processing unit 70b.

In the histogram processing section 70b, the digital signal output from the CCD section 70a is added for each pixel density of 256 gradations to obtain density information (histogram data) and, if necessary, the obtained histogram. The data is sent to the image processing CPU 74, and is also sent to the error diffusion processing unit 70c as pixel data.

The error diffusion processing unit 70c uses the error diffusion method, which is a kind of pseudo-halftone processing, that is, the method of reflecting the binarization error in the binarization judgment of the adjacent pixels.
The 8-bit / pixel digital signal output from the unit 70a is converted into 1-bit (binary), and a redistribution operation for faithfully reproducing the local area density in the original is performed.

However, each of the above-mentioned processing units included in the image processing unit 71 functions as necessary and may not function.

That is, in the multi-value quantization processing units 71a and 71b, the data binarized by the error diffusion processing unit 70c is converted again into 256 gradations.

In the synthesizing section 71c, a logical operation for each pixel, that is, a logical sum, a logical product, or an exclusive logical sum is selectively performed. The data which is the object of this calculation is the bit data from the pixel data and the pattern generator (PG) stored in the memory 73.

In the density conversion processing unit 71d, the relationship between the input density and the output density is arbitrarily set for the 256 gradation data signal based on a predetermined gradation conversion table.

In the scaling processing unit 71e, the pixel data (density value) for the scaled target pixel is obtained by performing interpolation processing with known data that is input according to the instructed scaling ratio. The main scanning is scaled after the sub scanning is scaled.

In the image processing section 71f, various image processings are performed on the input pixel data, and information collection such as feature extraction can be performed on the data sequence.

The error diffusion processing unit 71g performs the same processing as the error diffusion processing unit 70c of the image data input unit 70.

Processing similar to that of the error diffusion processing unit 70c is performed.

In the laser output section 72d, based on the control signal from the printer control CPU 79, the digital pixel data is output.
Data is converted into a laser on / off signal, and the laser is turned on / off.

The image data input unit 70 and the image data are input.
The data handled by the data output unit 72 is basically stored in the memory 73 in the form of binary data in order to reduce the capacity of the memory 73, but deterioration of the image data is taken into consideration. It is also possible to process in the form of 4-valued data.

Next, the reception state of the facsimile will be described with reference to FIG.

As a facsimile machine, a telephone line 78,
When the received information is received from the calling facsimile machine via the NCU 77 and the modem 76, the printer control CP

When the facsimile index button 21 is pressed by the operation panel 20 shown in the figure, the facsimile index function is set. facsimile·
When the index function is set, the image data received by facsimile and the index image data with page are combined by the image processing unit 71 and stored in the memory 73.

Then, this is read out and the final image is formed in the laser printer section 32 according to the read out reception information. The printer control CPU 79 has a facsimile reception counter and moves the index position for each reception. This counter is reset when the facsimile index function is released. FIG. 4 shows the position and size of the index mark printed. In the figure, the copy paper 20 to which the index mark is output is shown.

First received for facsimile first
Data index mark C1 (index position I
= 0) is output to the end portion along the long side 22 (on the right side in FIG. 4) upstream in the paper feeding direction of the copy paper 20.
The index mark C1 is Y from the short side 23 of the copy paper.
About 5% of the long side 22 in the direction, that is, L2 (about A4
14.8 mm) apart and the width L1 from the long side 22 in the X direction is about 3% of the short side 23 of the copy paper (about A4).
6.3 mm) and the length in the Y direction is L2.

The index mark C2 of the second data received after the first data has the same size as C1 at a position (I = 1) below C1 in the Y direction. The index mark C3 of the third data received after the data is C2.
Is output to the lower position (I = 2) in the Y direction in the same size as C1. The same applies to the fourth data and thereafter.

Here is an example: (a) shows the index mark of the printed first reception data, (b) shows the index mark of the printed second reception data, and (c) shows the plurality of printed print data. It shows a state in which the received data is overlaid. The numbers in the figure are the number of pages in the numerator and the total number of pages in the same data in the denominator. FIG. 6 is a flow chart showing the printing process of the index mark.

In the figure, first the page number (PAGE) P is 1,
0 is set in the index position I (6-1). When you receive a fax (6)
-2), if the FAX index mode is selected (6-3), it corresponds to each page of each reception data, for example, the label P of the memory if it is the Pth sheet (6-5), P After the memory of the first page is completed (6-6), 1 is added to P (6-7), and if the reception of data is completed (6-8), the total number of pages Pmax is set at the index position I. , The number of pages P, and the data of the label P stored in the memory are printed for each page (6-9). After printing, add 1 to the index I (6-1
0) Prepare to receive the next data. If the FAX index mode is not selected, another function (for example, normal
FAX reception) is performed (6-4).
