In step S6 of the figure, the type of paper set in the paper feed cassettes 735 and 736 of the color printer 2 is detected. Here, it is assumed that A4R and A3 sheets are stored in each cassette.

The process of forming an image on the A4R paper stored in the upper paper feed cassette 735 will be described.
(The recording density of the image formation of the color printer 2 is also 16 dots / mm as in the color reader 1) FIG. 19 shows a case of outputting the image information stored in the memory 1003 to A4R paper in the present embodiment. It is a figure which shows the output example of. As shown in the figure, when outputting to A4R recording paper, the image information stored in the memory 1003 is read by rotating 90 °.

The reading method for performing the 90 ° rotation will be described below.

First, prior to 90 ° rotation, the video interface 201 of the color reader 1 is set as shown in FIG. 5, and the image information is transmitted from the image storage device 3 to the video processing unit 12. Further, the CPU 1017 of the image storage device 3 sets the selector 1002 to the B side by controlling the output port 1016, and among the tri-state buffers 1009 to 1012,
The tri-state buffers 1011 and 1012 are enabled and the tri-state buffers 1009 and 1010 are set to the high impedance state (step S7 in FIG. 18).

The control unit 13 in the color reader unit 1 obtains the type information of the sheets set in the sheet feeding cassette 735 of the color printer 2 via the cable 511. In the present embodiment, the A4R paper is set on the upper stage, and from this information, the video processing unit in the color reader 1 displays the EN signal shown in FIG.
Outputs VCLK and ITOP signals.

For the ITOP signal, A4R paper is fed,
This is output when this paper is wound around the transfer drum and the leading edge of the paper is detected. Further, the EN signal is output by the laser output unit 71.
By detecting the laser light emitted from 1 (see FIG. 2), the logical "0" is obtained only for the width size of the A4R paper.

VCLK continuously outputs a frequency corresponding to one pixel of the laser. Also, the memory density is 16 dots
/ Mm, so VCL in the laser scan direction
The K number is 210 [mm] × 16 [dot / mm] = 33.
It becomes 60 dots, and the logic is "0" while the EN signal is input for 3360 clocks. Further, the control signal output from the video processing unit 12 and input to the image storage device 3 is input to the counters 1006 and 1007. EN
The signal is input to the clock input terminal of the counter 1006 and the clear terminal of the counter 1007. And
The VCLK signal is input to the clock input terminal of the counter 1007, and the ITOP signal is input to the clear terminal of the counter 1006.

FIG. 20 is a timing chart of control signals in the image copying apparatus according to this embodiment. When the EN signal 2009 shown in the figure is logic "0", the counter 1007 is cleared and all counter outputs output to the signal line 2012 are logic "0". Further, when the ITOP signal 2008 is logic “0”, the counter 1006 is cleared and all counter outputs output to the signal line 2013 are logic “0”.

When the VCLK 2004 is input to the counter 1007 after the EN signal 2009 becomes logic "1", the counter 1007 counts up one by one and outputs the signal line 2012.
Is output to. Then, the counter output output to the signal line 2012 is transmitted to the address terminal A1 of the memory 1003 via the valid tri-state buffer 1011.

After the P signal 2008 becomes logic "1", the EN signal 20
When 09 is input, the output counted up one by one is input to the signal line 2016. And the counter 10
The output of 06 is output to the terminals A0 to A13 of the memory 1003 via the enabled tri-state buffer 1012.
Entered in.

As described above, the output signal of the counter 1006 is supplied to the terminals A0 to A12 of the memory, and
The fact that the output signal of the counter 1007 is input to 3-A25 indicates that the outputs of the counters 1006 and 1007 at the time of image storage described above have been exchanged.

In the reading of the image information shown in FIG. 17, since the outputs of the counters are interchanged, the information in the V direction in FIG. 17 is read first, and the output of the counter 1006 in the H direction is counted every time one line is read. Up,
The process of reading the next one line in the V direction is performed.

The state of this processing is shown in FIG. In the figure, memory outputs, that is, signal lines 2019R, G,
The output signal output to B is at address 0 in the H direction,
This is data obtained by reading data from the 0th to 3360th lines in the V direction and then reading from 0th to 3360th lines in the V direction at the first address in the H direction. By repeating this processing up to the address 4752, the image processing for the A4 size original can be rotated by 90 ° and read from the memory 1003 in the A4R format.

Further, as shown in FIG. 21, the memory output,
That is, the signals output to the signal lines 2019R, G, B are 33 at the address of 4752 in the H direction, which is the reverse of that in the V direction.
The data in the direction of the 50th row to the 0th row is read out, and then the 3360th row to the 0th row, which is the reverse of the V direction, at the address 4751.
This is the data obtained by reading up to the row. By repeating this operation up to address 0, A4
It is also possible to rotate the image information, which was a document of a size, by 90 ° in the opposite direction to the direction shown in FIG.

Further, in the case where the image information of the A4 original is output by being rotated by 180 ° on the A4 size sheet, the image shown in FIG.
As shown in FIG. 2, by reading out the image in the opposite manner to that at the time of writing, the image can be rotated by 180 °. That is, the signals output to the signal lines 2019R, G, and B read the data at addresses 4752 to 0 in the H direction in the 3360th row in the V direction, and then read the V
The data at addresses 4752 to 0 in the 3359 line in the direction is read. Then, by repeating this operation up to line 0 in the V direction, the image rotated by 180 ° can be read (step S8 in FIG. 18).

Image information from the memory 1003 is output to the connector 1001 through the signal lines 2019R, 2019G, 2019B and the selector 1002. Then, this information is transmitted to the video interface 201 in the color reader unit 1 shown in FIG. The image information input to the video interface 201 is the color conversion circuit 47, LOG 48, color correction circuit 49, black character processing circuit 6
9, the density converting circuit 116, the magnification changing circuit 117, the repeating circuit 118, and the like, and then output through the printer interface 56, and the color printer 2 forms an image.

The image information sent from the color reader unit 1 is input to the PWM circuit 778 (see FIG. 2) in the color printer 2. The PWM circuit 778 binarizes the multivalued image information by pulse width modulation, and the binarized image information is sent to the laser output unit 711. The laser light emitted from the laser output unit 711 is polygon mirror 712.
Reflected by the f / θ lens 713 and the reflection mirror 71.
4, the surface of the photosensitive drum 715 is linearly scanned to form a latent image corresponding to the memory 1003 (step S10 in FIG. 18).

Since the processes after step S10 are the same as those in the above-mentioned color printer 2, the description thereof is omitted here.

The image rotation described above is performed by the memory 100.
The method used when reading from memory 3,
The method of rotating the image when writing to 3 can also be performed by the similar addressing method. Then, the memory 100
3 can be reduced or expanded by thinning out or interpolating data when writing to 3. Therefore, it is possible to perform image reduction and rotation processing in the image storage device 3 and combine the reduced and rotated images. <Reduced Layout of Plural Originals with Different Original Sizes> FIGS. 23 and 24 show the CPU in the control unit 13 in the image copying apparatus according to the present embodiment.
