FIG. 1 is a block diagram showing the configuration of the essential part of a facsimile apparatus showing an embodiment of the present invention. RAM83
The image information read from is input to the pixel data output unit 1. The pixel data output unit 1 outputs the received image information as a pixel data string signal when recording the image information on a recording paper. The pixel data output unit 1 stores a page memory 8 for storing at least one page of the received image information and a parallel memory from the page memory 8. The PS converter 9 converts the image information read out into serial image information. The main-scanning pixel counter 2 that counts the number of pixels in the main-scanning direction counts each state length that occurs between line synchronization signals, for example, the recording position of the output pixel data in the main-scanning direction. And a state counter 2a for setting the length of the left edge white area of the set recording paper and a left edge white area counter 2b for setting the length of the left edge white area. The sub-scanning line counter 3 counts the number of lines for setting the recording position in the sub-scanning direction.

Generates additional information data (mark data) as information data to be additionally recorded on the recording paper. Output data selection unit 7
Selects and outputs either the pixel data string signal D output from the PS conversion unit 9 or the mark data signal F output from the additional information generation unit 6 as the output data G to the print output unit 84.

When recording the received image information on recording paper,
The size information of the image information received from the transmission partner is set as the image information area in the image information main scanning width setting unit 4, while the size information of the recording paper set in the paper feeding unit is the recording paper main scanning width. It is set in the setting unit 5 as main scanning direction area information. The value thus set is compared with the values set in the counters 2a and 2b of the main scanning pixel counter 2 and the sub scanning line counter 3. The output data selection unit 7 selectively switches between the pixel data string signal D output from the PS conversion unit 9 and the mark data signal F output from the additional information generation unit 6 based on the comparison result, and performs serial output. The data signal G is output to the print output unit 84.

FIG. 2 is a timing chart of the line synchronization signal C given to the state counter 2a of the main scanning pixel counter 2 and the sub-scanning line counter 3 and the pixel data string signal D outputted from the pixel data output section 1. .
The serial output data signal G is S1 to S5 during one line output from the line synchronization signal C to the next line synchronization signal C.
Take 5 states. The first state S1 is an off period that starts in synchronization with the fall of the line synchronization signal C. The next states S2 and S4 are areas forcibly whitening at both ends of the recording paper, that is, white areas from both ends of the recording paper to the image information area, state S3 is an image information area, and states S2 to S4. The period is the recording paper width area, which is the area of the recording paper in the main scanning direction. The state S5 is an off period. In this embodiment, the H level indicates white and the L level indicates black. Further, although the states S1 and S5 are shown at the L level, they may be shown at the H level. Further, the state S3 is, for example, in the case of A4 size width and in B4 size as shown by the image information main scanning width.
It varies depending on the size range. On the other hand, the periods of states S2 to S4 also change depending on the recording paper width.

FIG. 3 shows states S2 to S in the embodiment.
4 is a timing chart for explaining No. 4 in more detail. In this timing chart, the image information main scanning width is shown as an A4 size width and the recording paper width is shown as a B4 size width. The pixel data column signal D output from the pixel data output unit 1 includes the states S2 and S shown in FIG. 2 for the periods of the states S2a and S4 following the state S1.
It becomes longer than the period of 4. This is because the image information main scanning width is the A4 size width even though the recording paper width is the B4 size width.

Mark data is inserted and recorded in the white area at the left end of the recording paper in the state S2a. The state counter 2a provided in the main scanning pixel number counting unit 2 is in the state S2a.
The left end white area counter 2b counts the state S2b indicating the left end white area of the recording paper in the B4 size image information main scanning width. In other words, when state S1 ends,
The left edge white area counter 2b counts the state S2b period, and when the state S2b ends, the output signal E from the main scanning pixel counter 2 is set to the L level, whereby the output data selection unit 7 outputs the additional information generation unit 6. The mark data signal F is selected and output. The period during which the output data selection unit 7 selects the mark data signal F is (S2a-S2
b) It is a period in which the output signal E from the counter is at L level in a shorter period. In this way, the additional information generation unit 6
The mark data F output from the output data selection unit 7 is output as a serial output signal G from the output data selection unit 7.

FIG. 4 is a timing chart explanatory diagram showing the operation of the state counters 2a and 2b constituting the main scanning pixel counter 2. The timing of each counter when executing the timing chart shown in FIG. 4 will be described below. First, at the start of facsimile reception, for example, A4 size width information is input from the communication control unit 88 to the main control unit 86 as main scanning width information of received image information. The main control unit 86 instructs the paper feed unit of the print output unit 84 to feed A4 size recording paper, but if there is no designated A4 size recording paper, the A4 size recording paper is used instead. The B4 size recording paper set in is fed. A value corresponding to the state S3 is set in the image information main scanning width setting unit 4, and values V1, V2a, V2b corresponding to the states S1, S2a, S2b, S4, and S5 are set in the recording paper main scanning width setting unit 5. , V3, V4, V5 are set.

A management table for obtaining values V1 to V5 corresponding to the states S1 to S5 from the image information main scanning width information and the recording sheet main scanning width information is prepared in the RAM 83 in advance, and the main control unit 86 makes the communication control unit 88. Based on the information from the paper feeding unit of the print output unit 84, the corresponding various values are read from the management table and set in the image information main scanning width setting unit 4 and the recording paper main scanning width setting unit 5, respectively. .

In the page memory 8 of the pixel data output unit 1, bit-mapped data as pixel data is stored in order from the data of the first pixel of the first line. Assuming that the data amount of 1 pixel is 1 bit (represented by a black and white binary value), the data A output from the page memory 8 is parallel data for 8 pixels, for example. The bits are sequentially converted into serial pixel data column signals D arranged in one column and output to the output data selection unit 7.

Subsequently, data is output to the print output unit 84 in synchronism with the conveyance of the recording paper. At the time of output to the print output unit 84, the value of the sub-scanning line counter 3 becomes the value indicating the first line by the line synchronization signal C synchronized with the recording paper conveyance prior to the serial output data signal G, and the state counter 2a displays V1 corresponding to S1 stored in the recording paper main scanning width setting unit 5 is set, and the countdown is immediately started. That is, the value of the state counter 2a is V by the clock given to the state counter 2a.
1 is subtracted from 1 in order. Eventually, the value of the state counter 2a becomes 0, and when the state S1 ends, the recording paper main scanning width setting unit 5 is then added to the state counter 2a.
The value V2a corresponding to S2a stored in the counter is set, the value V2b corresponding to the state S2b is set in the left end white area counter 2b, and the countdown starts immediately. At this time, no pixel data is output to the pixel data column signal D output from the PS conversion unit 9, the pixel data column signal D is at the H level as shown in the figure, and the pixel data column signal D is output from the main scanning pixel counter 2. Signal E to be H level,
Therefore, the serial output data signal G output from the output data selector 7 remains at H level.

When the value of the left end white area counter 2b becomes 0 and the state S2b ends, the signal E becomes L level, and the mark data signal F is output from the output data selection section 7 as the real output data signal G. For example, if the mark data signal F remains set to L, the black level is output while the signal E is L.

The value of the left edge white area counter 2b becomes 0,
When the state S2b ends, the value V3 corresponding to the state S3 stored in the image information main scanning width setting unit 4 is set in the state counter 2a, and the countdown is started. At this time, the main scanning pixel counter 2 sets the same clock as the clock supplied to the state counter 2a to P
By supplying to the S conversion unit 9, the state counter 2
A pixel data string signal D corresponding to the recording position indicated by a in the main scanning direction is output. Then, at that time, the signal E is already at the H level, and the pixel data column signal D is selected and output as the serial output data signal G. The address of the page memory 8 is, for example, 1 every 8 clocks.
Only be advanced. Eventually, when the value of the state counter 2a becomes 0 and the state S3 ends, the value V4 corresponding to the state S4 is set in the state counter 2a and the countdown is performed, but the pixel data string signal D holds the H level. , That signal is output as the serial output data signal G. When the value of the state counter 2a becomes 0, the pixel data string signal D becomes L level, the value V5 corresponding to the state S5 is set in the state counter 2a, and the countdown is performed.

The above-described operation is repeated each time the line synchronizing signal C is input, and the sub-scanning line counter 3 counts up each time, and when the predetermined value set in advance is reached, the operation of the left end white area counter 2b is performed. To stop the signal E
Is always at H level. In this way, the output of the mark data is completed and, for example, the bookmark SM shown in FIG. 9B is recorded.

As is clear from the above description, it is not necessary to provide the page memory 8 with the bitmap area for the margin including the mark data around the image information, and the memory can be used efficiently.

FIG. 5 shows an example of a plurality of mark data patterns provided in the additional information generating section 6. As a pattern in this embodiment, the mark data MD1 is white in both 2 bytes, the mark data MD2 is black in the first first byte, the second second byte is white, and the mark data MD3 is in the first first byte. It is white, the second second byte is black, and the mark data MD4 is composed of black information in both two bytes.

FIG. 6 shows an example in which various marks are added at different positions on the recording paper. By making it possible to select a plurality of mark data as shown in FIG. 5, for example, (a)
In the recording mark shown in (1), the mark data MD1 is output to the first predetermined number of lines, the mark data MD3 is output to the second predetermined number of lines, and the mark data MD2 and the mark data MD3 are output once again. It can be realized by The recording mark shown in (b) can be realized by setting a value corresponding to the distance f from the left end to the left end white area counter 2b and outputting the mark data MD4, and the recording mark shown in (c). Can be realized by setting the value described in the above embodiment for the left edge white area counter 2b and outputting the mark data MD4.

FIG. 7 is a block diagram showing a main part of an additional structure for adding mark data to an arbitrary position in the sub-scanning direction. When the mark data sub-scanning position setting unit 10 for setting an arbitrary sub-scanning position for adding the mark data is provided and the arbitrary sub-scanning position for adding is set, the line number corresponding to the set arbitrary sub-scanning position is set. The line counter 3b is provided in the sub-scanning line counter 3. The sub-scanning line counter 3 is counted up in synchronization with the line synchronization signal C, and when the line count value set in the line counter 3a is reached, the output data selection unit 7 selects and outputs the mark data signal F. Then, the mark data signal F is selectively output from the set line for a predetermined number of lines.

In the above description, it is also possible to set a desired value to the left edge white area counter 2b at a desired timing to control the signal E and add different marks to a plurality of different positions on the recording paper. is there.

Further, it is also possible to adopt a configuration in which the recording paper sub-scanning width setting unit 5 is not provided. In this case, the image information main scanning width setting unit 4
Is set to the number of clocks g from the line synchronization signal C to the start of the image information area and the image information main scanning width V3. The number of clocks g is set in the state counter 2a in synchronization with the line synchronization signal C, and the state counter 2a Mark data is selected until it becomes 0, image information is selected in the next state S3 phase, and mark data is selected when the state S3 phase ends. Then, the mark data MD shown in FIG.
It can also be configured to output 1. On the contrary, in the above-described embodiment, the mark data signal F is always set to the L level (black) and the signal E is controlled without providing the additional information generation unit 6, so that the signals E as shown in (b) and (c) of FIG. It is also possible to add a mark.
