The CCD reading unit 301 includes a CCD, a CCD clock driver, a signal amplifier from the CCD, and an A / D converter for A / D converting the signal.

Image data converted into a 6-bit digital signal is output from the CCD reading unit 301 and input to the shading correction unit 302.

After the shading correction unit 302 detects and corrects the shading amount of the light source, the lens and the like, the image signal is temporarily stored in the shift memory unit 303. The 303 has a shift memory for two lines, and when the image data of the Nth line is being written in the first memory, the Nth image is transferred from the second memory.
The image data of the -1st line is read. In addition to this, the shift memory section has a write address counter for writing image data in the shift memory, a read address counter for reading, and an address selector circuit for switching the address signals from these two counters. Details are shown in FIG.

Further, the scaling / movement processing unit 304 performs scaling or movement in the main scanning direction by changing the clock for writing the image signal in the shift memory, the clock for reading from the shift memory, and the timing for reading. The details of these will be described later.

The image signal output from the shift memory is the density processing unit 305.
Are inputted to the trimming processing unit 306 and binarized or dithered to be a binary signal. The trimming processing unit 306 forcibly processes any section of the main scanning line image data to “0” or “1” to enable image editing. Details will be described later.

The binary signal output from the density processing unit 305 is also input to the document position detection unit 307. Here, the binary signal is used to detect the position coordinates of the document on the document table glass by means described later.

The CPU unit 308 includes a CPU, ROM, RAM, a timer circuit, and an I / O interface. The CPU unit 308 controls the operation unit 310, controls the reader according to the setting made by the operator, and controls the printer by serial communication.

311 is a DC servo motor driver, and the CPU unit 308 presets speed data according to the magnification. The 312 is a fluorescent lamp driver that controls the ON / OFF of the fluorescent lamp and the light amount at the time of lighting. Reference numerals 313 and 314 are position sensors for the CPU unit 308 to know the position of the optical system. It is connected to the printer via connector JR1 and printer connector JP1. leader,
Control signals necessary for image data communication and serial communication are exchanged between the printers. Details will be described later with reference to FIGS. The horizontal synchronizing signal BD is taken in from the printer via JR1 and input to the clock generator 309. The clock generator 309 generates a CCD signal transfer clock and a shift memory read / write clock in synchronization with BD.

The circuit diagram of FIG. 4 shows the logic for detecting the coordinates.

The main scanning counter 351 is a down counter and represents the scanning position in one main scanning line. This counter is set to the maximum value in the main scanning direction (X direction) by the horizontal synchronizing signal HSYNC and counts down every time the image data clock CLK is input. The sub-scanning counter 352 is an up counter which is reset to "0" at the rising edge of VSYNC (image leading edge signal) and counts up with the HSYNC signal to indicate the scanning position in the sub-scanning direction.

The image data VIDEO binarized by the scanning is input to the shift register 301 in units of 8 bits. When 8-bit input is completed, the gate circuit 302 checks whether all 8-bit data are white images, and if YES, outputs 1 to the signal line 303. The F / F 304 is set when the first 8-bit white appears after scanning the original. This F / F is VSYNC
Have been reset by. After that, it will be kept set until the next VSYNC comes. When the F / F 304 is set, the latch F / F 305 is loaded with the value of the main scanning counter 351 at that time. This becomes the X ₁ coordinate value. Also, the latch 306 is loaded with the value of the sub-scanning counter 350 at that time, and this is the Y ₁
It becomes a coordinate value. Therefore, P ₁ (X ₁ , Y ₁ ) can be obtained.

The value from the main scanning counter 351 is loaded into the latch 307 each time 1 is output to the signal 303. When the latch 307 is loaded with the value from the main scan counter when the first 8 bits of white appeared, the data of latch 310 (which is set to the maximum value in the X direction at the time of VSYNC) and the comparator 309.
Compared in size. If the latch 307 data is smaller, the latch 307 data is loaded into the latch 310.
At this time, the value of the sub-scanning counter is loaded in the latch 311. This operation is processed until the next 8 bits enter the shift register 301. Thus, if the data of the latches 307 and 310 is performed for the entire image area, the minimum value in the original area X direction remains in the latch 310, and the coordinate in the Y direction at this time remains in the latch 311. Since the main scanning counter 351 is a down counter, the coordinate corresponding to the minimum value in the X direction represents the coordinate farthest from SP in the main scanning direction. This is P ₃ (X ₃ , Y
₃ )

The F / F 312 is a F / F which is set at the time when the first 8-bit white appears for each main scanning line, is reset by the horizontal synchronizing signal HSYNC, is set at the first 8-bit white, and is held until the next HSYNC. When the F / F 312 is set, the value of the main scanning counter corresponding to the position of the white signal first appearing in one line is set in the latch 313. Then, the magnitude is compared by the latch 315 and the comparator 316. The latch 315 is set to the minimum value "0" in the X direction when VSYNC occurs.

If the data in latch 315 is less than or equal to the data in latch 313, signal 317 becomes active and latch 3
13 data are loaded into latch 315. This behavior is HSY
It is performed between NC and HSYNC.

If the above comparison operation is performed for the entire image area,
In 5, the maximum value of the document coordinates in the X direction, that is, the X coordinate of the white signal at the point closest to the scanning start point in the main scanning direction remains.

This is X ₂ . When the signal line 317 outputs, the value from the sub-scanning counter 352 is loaded into the latch 318. This becomes Y ₂ , and P ₂ (X ₂ , Y ₂ ) coordinates are obtained.

The latches 319 and 320 are loaded with the values of the main scanning counter and the sub-scanning counter at each time when 8-bit white appears in the entire image area. Therefore, when the pre-scanning of the original is completed, the count value at the time when the last 8-bit white appears appears in the counter.

This is P ₄ (X ₄ , Y ₄ ).

The above eight latches (306,311,320,318,305,310,315,31
The data line of 9) is connected to the bus line BUS of the CPU processing unit 308 of FIG. 2, and the CPU processing unit 308 reads this data at the end of the prescan.

FIG. 9 shows a circuit diagram of the shift memory. The write address counter 904 is an address counter when writing data in the shift memory 907.
Is an address counter for reading data from the shift memory 907. The address selector 906 receives a command from the CPU unit 308 via the I / O port 901 and receives the address signal of the write address counter 904 and the read address counter 9
This is for selecting any of the 05 address signals to address the shift memory.

The I / O registers 902 and 903 store preset values to the write address counter 904 and read address counter 905, respectively.
This is a register provided by the unit 308.

Write address counter 904, read address counter 9
Reference numerals 05 are both down counters, to which the WST signal and the RST signal for instructing the start of the count operation are input, respectively, and the write clock WCLK to the shift memory and the read clock RCLK from the shift memory are input.

915,916 are exclusive OR gates for determining the image area, OF
Is a signal for controlling it. When 1 is set, the inside of the frame determined by the ST counter 912 and EN counter 913 is masked, the outside of the frame is used as an output image, and when 0, the inside of the frame is used as an output image and the outside of the frame is masked.

910 is output from the shift memory and passed through the density processing unit 908.
An AND gate that controls the output of the image data that has become a value signal, 917 is an AND gate that determines whether the mask portion is output as white or black, and BB is a signal that controls it, and when it is 1, black is output. When it is 0, white is output.

911 is VIDEO output by the gates 910 and 917
, 909 is an exclusive OR gate for controlling the black-and-white opposite point of the image data, and IN is a signal for controlling it, which is the original image when 1 and inverted when 0.
Each signal is output by the CPU unit 308 in a mode designated by the operator.

The ST counter 912 and the EN counter 913 are START BIT COUNTER and E for outputting the image only to a predetermined area.
With the ND BIT COUNTER, the CPU unit 308
Resets the count data for the gate. The flip-flop 914 is set by the count-up of the ST counter 912 and reset by the count-up of the EN counter 913. Figure 10 shows the operation.

For example, in the case of the OF signal 1, when the Q of the F / F 914 becomes 1 by the count up of the ST counter 912, the output of the gate 915 becomes 0, and the output of the gate 910 is masked without being output until the EN counter 913 counts up. Instead, the output of gate 916 is 1 during that time, so when BB signal is 1, gate 917 is 1.
The gate 911 outputs 1 and becomes a black mask.

Conversely, when OF = 1, BB = 0, the white mask is used. When OF = 0, the outputs of the gates 915 and 916 are 1,0 during that time respectively, so BB
When = 1, the outside of the trimming is black, and when OT = 0 and BB = 0, the outside of the trimming is white.

Next, the principle of scaling will be described.

The scaling in the sub-scanning direction is performed by changing the scanning speed of the optical system. CPU unit 308 changes the magnification specified by the operator
PLL that calculates the speed of DC servo motor and corresponds to that speed
The frequency is calculated and preset in the motor driver shown in Fig. 311 before scanning. The transport speed of the printer is always
Since it is 180mm / sec, the speed is 180mm when it is magnified twice.
It moves at a speed of 90 mm / sec, which is 1/2 of that of / sec, and when it is reduced to 1/2, it moves at a speed of 360 mm / sec, which is twice as fast.

The scaling in the main scanning direction will be described with reference to FIG.

The serial signal after A / D conversion from the CCD output at a constant frequency is sampled at the clock rate according to the magnification.

At the same magnification, as shown in Fig. 11-1, write clock equal to transfer clock CLK from CCD is written in shift memory with WCLK, or as shown in Fig. 11-2, output clock to printer is equal to read clock VCLK. Read from shift memory with RCLK.

For example, when reducing by 1/2, write clock W to the shift memory
As shown in Fig. 11-3, the transfer clock CLK is 1/2, and the original bit of the original information is sampled every 2 bits, and as shown in Fig. 11-2, it is read out with the same read clock RCLK as the output clock VCLK. / 2 reduction is realized.

When expanding to 2 times, when writing to the shift memory, it is written as shown in Fig. 11-1 as in the case of equal magnification, and when reading from the shift memory, output clock VCLK to the printer as shown in Fig. 11-4. On the other hand, if it is read at a half clock rate, one bit is added to each bit of original information, and a double expansion can be realized.

The principle of image movement will be described with reference to FIGS. 12-1 and 12-2.

The sub-scanning direction is realized by giving the original image scan and VSYNC output timing to the printer as shown in FIG. 12-1.

For manuscript When the optical system reaches the position of, the output that does not move is obtained as shown in the figure that VIDEO output with VSYNC, When the optical system reaches the position of, the output moved to the back like VVIDEO output with VSYNC is obtained, When the optical system reaches the position of, the output moved to the front like VSYNC and VIDEO output is obtained.

Regarding the main scanning direction, as shown in FIG.
Write address counter 90 via I / O registers 902, 903
This is performed by relatively changing the down count start address given to 4 and the read address counter 905.

For example, if the read start address is RADR1 with respect to the write start address WADR to the shift memory, the image data X ₀ corresponding to the address WADR has moved to the right with respect to the output main scan width VIDEO ENABLE, as shown in Figure 12-2. Is understood. If the read start address is PADR2, then Fig. 12-
Data corresponding to shift memory address 0, such as 2
It can be seen that X ₃ is still VIDEO ENABLE and is moving to the left. The effective image section signal shown in FIG. 12-2 is the ST counter 912 and E to counter 913 and F / F91 shown in FIG.
4 is a trimming section signal composed of gates 915, 916, 917, 910, 911, and is necessary in order to make an invalid image outside the address 0 to WADR in the shift memory of FIG. 12-2 a white signal.

The interface signal timing will be described with reference to FIGS. 13 and 14.

The BEAM-DETECT signal BD is for synchronizing the rotation of the polygon scanner of the printer when connected to the printer, and corresponds to the leading edge signal of each main scanning line. VIDEO is an image signal, and each line outputs 4678 pixels with a width of approximately 56 NS per pixel. VIDEO is synchronized with BD when connected to a printer, and is output in synchronization with an internal pseudo horizontal synchronization signal (hereinafter referred to as HSYNC) when transmitting to another unit. VIDEO
ENABLE is a section signal in which 4678 of the image data is output, and is output in synchronization with BD or HSYNC. VSYNC
Is a signal indicating an image section in the sub-scanning direction. PRINT R
The EQUEST signal is a signal indicating the paper feed possible state in the printer, and in response, the reader issues a paper feed command with the PRINT signal, and then considers the magnification, trimming area, and movement amount corresponding to the copy mode set by the operator. After time T1
Output VIDEO with VSYNC. OHP and VTOP are input signals from the sensors shown in FIGS. 313 and 314 in FIG. 3, which indicate the position of the optical system of the reader. BACK and FORWARD are shown in Fig. 3 CPU
It is a signal given from the unit 308 to the motor driver 311 for driving the optical system to control the backward movement and the forward movement.

In Fig. 14, S.DATA, S.CLK, CBUSY, SBUSY are readers,
This is a signal line for communication between printers. S.DATA,
Both S.CLK are 8-bit serial data and clock, both of which are bidirectional lines. CBUSY is output when the reader outputs data and clock, and CBUSY is output when the printer outputs data and clock. As an example of the contents communicated serially, there is a copy start from the reader to the printer as shown in the timing chart of FIG. 13 and a copy-stop command.

An outline of the editing function trimming auto mode according to the present invention will be described with reference to FIGS.

In this mode, the magnifications MX,
When the size DX, MX, DY, MY multiplied by MY is larger than the paper size PX, PY, the original is automatically divided and multiple sheets (main scanning
NX sheets, sub-scanning NY sheets, total NX / NY sheets) are used to output copies of output sizes DX, MX, DY, MY as shown in Fig. 7. At this time, if DX / MX> PX and DY / MY> PY, the result is as shown in Fig. 7, but if DX / MX> PX and DY / MYPY, then as shown in Fig. 8-1 in the sub-scanning direction. Is paper 1
One sheet is sufficient, and the sensor automatically moves in the sub-scanning direction. Conversely, when DX / MX and PXDY / MY> PY, the center is automatically moved to one sheet in the main scanning direction as shown in Fig. 8-2. Also DX / MXPX and DY / MY
In the case of PY, as shown in FIG. 8-3, one sheet for both the main and sub scanning directions, that is, one sheet in total is sufficient, and the center is automatically moved in both scanning directions.

FIG. 5-1 shows a setting flow of the editing function trimming / auto according to the present invention. In the display section 123 of the operation section A1 shown in FIG. 2, when there is usually no error, it is displayed like, and when the soft key SK6 is pressed, it is displayed. Indicates that trimming is not set as an editing function, and center movement is set as a moving function. Press the corresponding SK6 on the ETC at to display the current setting mode of other functions. Press SK4 or SK5 at to set other movement functions. It becomes like pressing SK1 or SK2 at.
Shows that there are four editing functions: trimming, masking, book, and those cancels. Furthermore, "none !!" indicates that none of them are currently selected. When SK1 is pressed here, the trimming mode setting is displayed as if it were entered, and one of the automatic division of the original according to the present invention, that is, the trimming auto mode, and the arbitrary designation mode by the operator of the trimming area is selected. When SK3 is pressed at, trimming auto is selected and the display is as shown and the setting is completed.

FIG. 5-2 shows an execution flow of the editing function trimming auto copy according to the present invention. First, a preliminary scan is performed to recognize the position and size of the document (SP501). By the coordinate detection logic described above, for example, the coordinates of P ₀ and P ₁ of the original placed on the glass as shown in FIG. 6-1 are obtained, and the data areas DX0, DX1, DY0 and DY1 on the RAM are set. And the size of the document in the X direction (main scanning direction) DX1-D calculated from the coordinates
X ₀ and Y-direction data area DX on the size DY1-DY0 of (sub scanning direction) RAM, respectively excisional the DY (SP502).
Next, the length in the main scanning direction of the paper selected by the operator,
Set the sub-scan length to the RAM area PX, PY (SP50
3). In addition, the operator selected the magnification in the main scanning direction,
The magnification in the sub-scanning direction is set in the areas MX and MY on the RAM (SP504).

Next, DX, MX = NX, PX-ax (0 <ax <PX) NX and DY
MY = NY · PY−ay (0 <ay <PY) is calculated and RA is calculated as RA
Set to the data area on M (SP505).

From this calculation, the paper size selected by the operator is NX sheets in the main scanning direction and NY sheets in the sub-scanning direction to form a size that is the original size multiplied by the operator's selected magnification.
It turns out that you need one. On the other hand, the operator selected paper size PX, PY and magnification MX, MY to TX = PX / MX, TY = PY
The size of the trimming area is calculated back by / MY and set to the areas TX and TY on the RAM (SP506). From the above NX, NY,
To read the document size DX by trimming the NX image area of the above TX size in the main scanning direction, SX = (DX-
TX * NX) / (NX-1) is calculated, and the trimming areas adjacent to each other by the length of SX are overlapped in the main scanning direction. Similarly in the sub-scanning direction, SY = (DY-TY ・ NY) / (NY-
1) is calculated and these SX and SY are set in the area on RAM (SP507). About the above NX, NY, TX, TY, SX, SY No. 6-2
Illustrated in the figure.

A counter for executing trimming in the order shown by the arrow in FIG. 6-2 is secured in the areas i and j on the RAM, and the initial value 0 is set (SP508).

In this copy mode, the operator only needs to set the conditions for the original, magnification, and paper, and the CPU automatically calculates the number of paper sheets required to compose the output of the desired size. Displays NX / NY in the number display area (SP509). Next, the counters i and j for executing the trimming are each incremented by 1 (SP51
0, SP511).

Generally, "(i, j) trimming area = jth time in the main scanning direction and ith time in the sub scanning direction" shown in FIG. 6-2.
That is, if the coordinates that determine the NY (i-1) + jth trimming area are KXi ₀ , KXi ₁ , KYj ₀ , KYj ₁ , these are KXi ₀ = DX ₀ +, as can be seen from FIG. 6-2. (I-1)
・ (TX-SX), KXi ₁ = KXi ₀ + TX, KYi ₀ = DY ₀ + (j-1)
-(TY-SY), KYj ₁ = KYj ₀ + TY. These are calculated and set in the RAM area (SP512).

Next, while scanning the image, only the necessary area is trimmed by the above-mentioned means based on the trimming area coordinates calculated previously, and the scaling processing of MX and MY is performed and output to the designated paper (SP513).

When the image reading is completed, the number display is counted down by one, that is, NXNY-NY (i-1) -j is displayed (SP514).
FIG. 15 shows the change in the number display on the number display area, taking NX = 2 and NY = 3 as an example. This allows the operator to know how many more sheets will be output. Next, in the sub scanning direction, NY
It is determined whether or not the trimming has been performed twice (SP515). If NO, the trimming execution counter j in the sub-scanning direction is incremented by 1 (SP511), and the process proceeds to the next trimming process. If YES, after clearing the trimming execution counter j in the sub-scanning direction to 0 (SP516), in the main scanning direction NX
It is determined whether the trimming has been performed twice (SP517). In the case of NO, the trimming execution counter i in the main scanning direction is incremented by 1 (SP510), and the sub scanning direction counter j is cleared to 0. Therefore, this is also incremented by 1 to proceed to the next trimming process. If YES, total NX
-The trimming process is performed NY times and the output of NX / NY copies is completed, so the copy in this mode ends.

By the above procedure, the original placed on the platen glass as shown in Fig. 6-1, NX while overlapping the trimming areas of TX, TY size by SX, SY as shown in Fig. 6-2・ N
Divide into Y pieces and trim in order in the direction of the arrow for a total of N
X / NY copy output can be automatically obtained.

On the other hand, the output copy is printed in the main scanning direction as shown in FIG.
MX / SX When MY and SY are overlapped and pasted in the sub-scanning direction, a magnified copy with a main scanning length DX / MX and a sub-scanning length DY / MY, which could not be obtained with a single copy sheet, can be obtained. .

In this embodiment, since the maximum paper size is A3 and the maximum magnification is 400%, the maximum output obtained is 1188 mm in the main scanning direction and 1680 mm in the sub scanning direction, that is, two A0 sheets.

[Effect] As described above, according to the present invention, an image obtained by vertically dividing a plurality of recording papers into a plurality of vertically and horizontally images based on the size of the image to be recorded, the size of the recording paper, and the scaling factor is used. If you want to create a single large image by gluing multiple recording papers in the vertical and horizontal directions by determining the coordinates of multiple areas that are divided so that they are recorded in the horizontal and horizontal directions. Since it is only necessary to overlap the overlapping recording areas of a plurality of recording papers, it is possible to easily create a large image.
