The shift register 161 is supplied with erase data stored in the memory 140 described above. As will be described later, this erase data is generated based on an erase range preset in the main processor group 71, and the memory 140 has a high level signal II 1 in the erase range portion.
1+, and a low level signal ITOII is stored in the other portions. That is, in this memory 140, for example, the capacitance in each column direction is the same as that of the light emitting elements 1 constituting the erasing array 150.
It is composed of RAM matched with the number of 52,
Under the control of the main processor group 71, high level signals and low level signals are stored at predetermined addresses as shown in FIG.

In the above configuration, an erase operation will be explained.

As described above, when the first carriage 411 and the photosensitive drum 10 are operated while the erased data is stored in the memory 140, the memory 140
One column of data is sequentially read out in the row direction (as shown in FIG. 31). The read data D1 is transferred to the shift 1 to register 161 of the array driving section 160 in response to the clock signal CLK. After one column of data has been transferred to the shift register 161, when the charged portion of the photosensitive drum 10 reaches the erase array 150, the main processor group 71 outputs a latch signal LTH, and the shift register 161 outputs a latch signal LTH. The data stored in register 161 is supplied to store register 162 .

That is, since the erasing array 150 is arranged between the charger 11 and the exposure section Ph, one row of data outputted from the memory 140 has, for example, an angle of θ! between the erasing array 150 and the exposure section ph! Assuming that the photosensitive drum 10 is rotating at an angular velocity ω, the latch signal LTI- is supplied to the store register 162 before θ1/ω.
1 output timing is controlled.

Each switch element 163 of the switch circuit 164 is controlled by the output signal of the store register 162. That is, when the output level of the store register 162 is high level, it is turned on, and when it is low level, it is turned off. As a result, the light emitting elements 152 connected to each switch element 163 are turned on when the switch element 163 is on, and are turned off when the switch element 163 is off. Therefore, among the charged parts of the photoreceptor drum 10, the part where the light emitting element 152 is turned on is charge-free, and even if the charge-free part is subsequently exposed, a static Ti latent image is not formed, and the original image is not erased. It means that it was done. Thereafter, the data in the memory 140 is read out column by column in the same manner, and the image is erased.

Note that the arrangement position of the erasing array 150 is not limited to that shown in FIG. 26, but as shown in FIG. It is also possible to configure the data to be erased.

Next, the gist of the invention will be further explained.

In this invention, it is possible to edit and copy the address written on the second document with a small movement of the variable magnification lens block 8, and furthermore, it is possible to edit and copy the address written on the second document with a small movement of the lens block 8 for changing magnification. The setting position of the second original on the original table 2 is displayed.

FIG. 3(a) shows a second document G2 to which the present invention is applied. The width W2 of the second original G2 is approximately 1/2 of the maximum original width, for example, the longitudinal width W1 of the first original IGt of A4 size shown in FIG. In this second document G2, a plurality of addresses are arranged, for example, in the row direction and the column direction. The arrangement pitch of these addresses is, for example, px in the row direction and Py in the column direction, and each document has Pxxn addresses arranged in the row direction and pyxm addresses in the column direction. This array pitch can be changed depending on the size of the operation, but here there are two types of array pitches, and these array pitches are determined in advance by the main processor group 7.
1 is stored. Furthermore, the pitch px in the row direction
is set to, for example, an integral multiple of the drive pitch of the pulse motor 67 that drives the variable magnification lens block 8, and the pitch Py in the column direction is set to, for example, the drive pitch of the pulse motor 33 that drives the first carriage 411. is set to an integer multiple of .

Next, the setting position of the second document G2 configured as described above on the document table 2 will be explained.

The second original IG2 is set along the fixed scale 22 of the document table 2, and this setting position is set to the first original IGt under the control of the main processor group 71 during editing and copying, which will be described later. Set address entry air En
is displayed using the spot light source 131 on the fixed scale 22 side according to the position of the image.

That is, when the edit/copy designation key 30f is operated, the spot light source 131 is moved to the vicinity of the fixed scale 22 after an instruction operation for the address entry area En, which will be described later.

In this position, the light emitting element 132 is turned on, and in this state, as shown in FIGS. 1(a) and 1(b), the first original Gr

31 is reciprocated for a predetermined period of time, and the set position of the second original G2 is displayed.

In this way, the second original G2 is 1/2 of the first original G1.
, and this second raw IG2 is the size of the first raw UAGl.
By changing the address writing area En according to the position of the address writing area En, the moving distance of the variable magnification lens block 8 can be reduced.

That is, as shown in FIGS. 2(a) and 2(b), the variable magnification lens block 8 has a distance flt in the direction of the set position of the second original IG 2.
It is sufficient to move within the range of lt or 12.

Note that the image of the first original G1 that has been copied onto the paper is supplied to the transfer unit again with the image upside down in the drawing. Therefore, the setting position of the second document G2 is

It is moved according to the operation of 0d.

When the position designation key 30e is operated at a desired position, that position is stored in the main processor group 71 as a new address entry area En instead of the preset address entry area. After the operation for changing the entry area En is completed in this manner, or when the operation keys 30a to 30d are not operated in step ST2, the control is shifted to step ST4. In this step ST4, the setting position δ of the second document G2 is displayed by the spot light source 131 as described above, according to the preset address entry area En or the newly set address entry area En. . As a result, if the displayed setting position and the actually set position of the second original IG 2 are incorrect, the second original IG 2 is reset according to this display. After this, in step STs, it is determined which of the list designation keys 30h and 30i is selected, and the arrangement pitch of images in the second document corresponding to the selected list designation key is set. .

Thereafter, in step ST6, it is determined whether or not the color change key 30q has been operated. As a result, color change key 3

At this time, an image of Ntt in the second original m G 2 shown in FIG. The pulse motor 67 is driven in accordance with the arrangement pitch of the images on the second document G2, and the variable magnification lens block 8 moves the image N1s so that it is formed in the address entry area En of the sheet. Further, under the control of the main processor group 71, the memory 140 stores N of the second document G2 as shown in FIG. 6(a).
A low level signal is stored in the storage area corresponding to ll, and a high level signal is stored in the storage area other than Ni+. The data stored in this memory 140 is stored in the first carriage 4.
The signal is read out in synchronization with the operation of step 11, and is supplied to the array driving section 160 described above. Therefore, as shown in FIG. 7(a), the surface of the photoreceptor drum 10 has a second original! Only the image corresponding to Nsl of iG2 is formed. The image formed on the photoreceptor drum 10 is transferred to the paper that is fed in synchronization with the rotation of the photoreceptor drum 10. Therefore, on this sheet, as shown in FIG. 7(b), an image of the portion N1 of the second document G2 is formed in the address entry area En of the first document G1.

This image is formed using red toner when the color change key 30a is operated, and is formed using black toner when the color change key 30q is not operated. The paper P on which the images of the first original G1 and the second original G2 have been edited and copied in this way is discharged to the tray 25 in step 5T14. After this, step 5T1s
At , it is determined whether or not editing copying has been completed for the set number of sheets. As a result, if not all have been completed yet, the control is transferred to step 5T13,
Edit copying is performed as described above.

That is, for the second paper, N2 as shown in FIG. 3(a)
The variable magnification lens block 8 is moved so that the image No. 1 is formed in the address entry area En of the first original IGt, and at the same time, the images other than N21 are erased from the photoreceptor drum 10 by the erase array 150. Yes, memory 140
