Next, the document image erasing means will be explained.

21 and 22, the first carriage 411 is provided with a guide shaft 130 along the lamp 4 in the part where the light of the lamp 4 is blocked, and this guide shaft 130 has a guide shaft 130 which is used to mark the erasing range of the document. Spot light source 1 as a means of giving instructions
31 is movably provided. This spot light source 1
As shown in FIG. 22, reference numeral 31 includes a light emitting element 132, such as a light emitting diode or a lamp, and a lens 133, which are provided opposite to the document table 2.
The light generated by the lens 2 is irradiated onto the document table 2 by the lens 133 as light from the slot 1 having a diameter d. This spot light has a brightness that allows it to pass through the document G set on the document table 2, which is, for example, as thick as a postcard.

The spot light source 131 is connected to a timing belt (toothed bell 1 - > 134) disposed along the guide shaft 130. The pulley 137 is connected to the pulley 137. Therefore, by rotating the pulse motor 135, the spot light source 131 is moved in a direction perpendicular to the scanning direction of the first carriage 411. A position sensor 138 consisting of a microswitch that detects the initial position of the spot light [131] is provided on the first carriage 411 located at the end on the side of the pulse motor 135. For example, when the spot light source 131 is moved, first, The spot light source 131 comes into contact with the position sensor 138 to detect the initial position.

Next, using FIGS. 23 and 24, the spot light source 1
A method of specifying a predetermined range of a document using 31 will be explained. This spot light source 131 is connected to the operation key 3 described above.
By operating 08 to 30d, the light emitting element 132 is moved in a lit state. That is, the operation keys 30b, 3
When 0d is pressed, the motor 33 is driven, and the first carriage 411 and the spot light source 131 are moved in the scanning direction (the direction of the arrow y shown in FIG. 23). In addition, the operation key 30
When a, 30G is pressed, the motor 135 is driven, and the spot light source 131 is moved in a direction perpendicular to the scanning direction (direction of arrow X shown in FIG. 23).

The operator operates the operation keys 308 to 30d while visually viewing the spotlight transmitted through the document G, and presses the position designation key 30e after moving the spotlight to point S1 on the document G shown in FIG. 24, for example. Then, the coordinate position specified by this Sl is stored in the main processor group 71 shown in FIG. When the position designation key 30e is pressed while the spotlight is moved to 82 points on the document G of the same type, the positions of the 82 points are stored in the main processor group 71. The position of this spot light can be detected, for example, by counting the number of drive pulses of the pulse motor 33.135.

On the other hand, as shown in FIG. 25, an erasing array 150 serving as erasing means is provided close to the photosensitive drum 10, for example, between the charger 11 and the exposure section Ph. As shown in FIGS. 26 and 27, this erasing array 150 includes a plurality of light-shielding cells 151 arranged in a direction perpendicular to the rotational direction of the photoreceptor drum 10, and inside each of these light-shielding cells 151. A light emitting element 152 made of, for example, a light emitting diode is provided as shown in FIG. A lens 153 is provided to focus the light on the surface of the photoreceptor drum 10.The number of light emitting elements arranged in the erasing array 150 matches, for example, the capacity of the memory 140 in the column direction. ,
Assuming that the distance between the light emitting elements 152 is P and the number of light emitting elements 152 is N, the total length of the erasing array 150 is Q-NxP.

The erase array 150 is driven by the array driver 160 described above. As shown in FIG. 29, this array driving section 160 includes a shift register 1 having the same number of bits as the number of light emitting elements 152 constituting the erasing array 150.
61, a store register 162 in which the contents of the shift 1 to registers 161 are held, and a switch circuit 164 comprising a plurality of switch elements 163 that are controlled on and off by each output signal of the store register 162; Movable contact pieces 163 of these switch elements 163
a is grounded, and fixed contacts 163b are connected to each cathode of the light emitting elements 152 constituting the erasing array 150, respectively. The anode of each of these light emitting elements 152 is connected to the power supply Vcc via a current limiting resistor R, respectively.

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.
11, a low level signal '°O' is stored in the other portions. That is, in this memory 140, for example, the capacity in each column direction is the same as that of the light emitting elements 152 constituting the erase array 150.
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 in a state where the erase data is stored in the memory 140, the memory 140 is operated.
Data for one column is sequentially read out from 40 in the row direction (as shown in FIG. 30). This read data D1 is transferred to the shift 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 output from the memory 140 is generated when the angle between the erasing array 150 and the exposure section ph is θ1, for example. Assuming that the photosensitive drum 10 is rotating at each speed, the output timing of the latch signal LTH is controlled so that it is supplied to the store register 162 before θ1/ω.

Each switch element 163 of the switch circuit 164 is controlled by the output signal υj 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 portions of the photoreceptor drum 10, the portion where the light emitting element 152 is turned on is neutralized, and even if this neutralized portion is subsequently exposed to light, an electrostatic latent image is not formed, and the original image is erased. It means that it was done. Thereafter, data of the same type is read out from the memory 140 one column at a time, and the image is erased.

Next, the gist of the invention will be explained. In this invention, it is possible to edit (combine) and form an image of the second document at a desired position of the first document. FIG. 4(a) shows a first original G1, and a part of this first original tKGs is provided with an entry area En for list items (page circle, ■, etc.). Further, FIG. 2B shows the second original G2. This second manuscript G2
For example, in the row direction and column direction, ■, box 1, ■, f'MIm
, etc. are arranged in list items. The arrangement pitch of these list items is, for example, Px in the row direction and Py in the column direction.
For each document, list items pxxn are arranged in the row direction and pyxma are arranged in the column direction. It is assumed that this arrangement pitch is stored in the main processor group 71 in advance. 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,
The pitch Py in the column direction is, for example, the first carriage 41
The pitch is set to be an integral multiple of the drive pitch of the pulse motor 33 that drives the pulse motor 1.

In the above configuration, the editing (synthesis) copying operation will be explained. In this case, as shown in FIG. 1, the first and second originals Gl and G2 have a fixed scale
The second document G2 is placed face down on the fixed scale 22 side. In this state, the number of copies is set using the numeric keypad 302 of the operation panel 3o, and the list number designation key 30i
, and use the numeric keypad 302 to specify the number of the list item to be imprinted (STo). For example, a designation is made as a ten copy. After specifying the number you want to imprint, operate the import center designation key 30f (ST1
), flf The main processor group 71 is set to the edit copy mode (composition mode), and the operations shown in FIG. 3 are performed.

That is, first, in step ST2, the spot light source 131 is turned on, and this spot light source 131 is moved to the central part 1' of the entry area En for the list 1 previously stored in the main processor group 71, The center En' of the writing area En is displayed on the first document Gl by the transmitted light. In this case, the center En- of the entry area En corresponds to the center point φ in the list frame (St) of the second document G2 (see FIG. 4(b)).

After that, in step ST3, it is determined whether the operation keys 30a to 30Cl for moving the spot light source have been operated. As a result, if the operation keys 30a to 30 (l) are operated, the process goes to step ST4 J3, where the spot light source 131 is turned on as described above, and as shown in FIG. will be moved.

When the position designation key 30e is operated at a desired position, the entry area En corresponding to that position, that is, the center portion En-, is stored in the main processor group 71. After completing the change operation of the entry area En in this way,
Alternatively, in step ST2, the operation key 30a
~30d is not operated, the control returns to step ST
Moved to +. In step ST4, it is determined whether or not the color change key 300 has been operated. As a result,
If the color change key 30a is operated, step S
At Ts, if the color change flag is set and the color change key 3C1 is not operated, control returns to step ST.
7. In this step ST7, the copy key 30
It is determined whether or not t has been operated. As a result, when the copy key 30r is operated, the first carriage 41+ is moved in the range from Ya to Yb shown in FIG. be done.

Then, the sheet on which the image of the first original Gl has been copied is guided into the multiple copying unit 28 and stored in the stacking section 28a. In this way, when the first original G1 has been copied by the set number of sheets, control is transferred to step 278-9. In this step STa, the state of the color change flag is determined, and if this flag is on, in step 5TLO, a phenomenon occurs in which red 1-toner is accommodated from the developing device 122 that accommodates black toner. 121. After this, the control goes to step 5Tii
will be moved to In this step 5Tit, the first carriage 411 exposes and scans the second document, operates the erasing array 150 and variable magnification lens block 8, and supplies the document from the accumulating section 28a to the transfer section again. In the entry area of the form [n, enter the second original tEi G2
The list items with the specified numbers arranged in the above are sequentially copied.

That is, first, the first carriage 411 is
b to YC, and the second original G2 is exposed and scanned. At this time, for the first paper, see Figure 4<
The image of the list N22 corresponding to the number y in the 0/θ space is formed on the second original G+2 shown in FIG. That is, the main processor group 71 moves the images of the list N22 corresponding to the set arrangement of images in the second document G2 so that they are formed in the first entry area En. Furthermore, under the control of the main processor group 71, the memory 140 stores a low level signal in the storage area corresponding to the list N22 of the second document G2, as shown in FIG. A high level signal is stored in the storage area.

The data stored in this memory 140 is stored in the first carriage 411.
The data is read out in synchronization with the operation of , and is supplied to the array driving section 160 described above. Only the images that do so will be 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, as shown in FIG. 6(b), this form has an entry area En for the first original IGx.
Then, the picture @ (circulation) of the list N22 corresponding to the number @ (b) in the second original image G2 is formed. This image is formed with red toner when the color change key 300 is operated, and when the color change key 3C1 is not operated,
Formed by black toner. The paper P on which the images of the first original TAX 01 and the second original G2 have been edited and copied in this way is discharged to the tray 25 in step 5T12.

Thereafter, in step 5T13, it is determined whether editing copying has been completed for the set number of copies. As a result, if all the processes have not been completed yet, control is transferred to step 5T11, and editing and copying is performed as described above. That is, the variable magnification lens block 8 is arranged so that the images of the list N22 corresponding to the numbers shown in FIG. is moved, and along with this, erase array 1
50, the memory 1 is erased from the photoreceptor drum 10 so that images other than the list N22 corresponding to the number @[stock] are erased from the photosensitive drum 10.
Erased data is stored in 40 as shown in FIG. 5(b). Further, the variable magnification lens block 8 is moved so that the image of the list N22 corresponding to the number ■ in the second document G2 is formed on the third sheet, and along with this,
The erasing array 150 is controlled so that images other than those in list N22 corresponding to number α9 are erased. Zarani, n+1
The variable magnification lens block 8 is moved so that the image of the list N22 corresponding to the number in the second document G2 is also formed on the second document G2, and at the same time, the images other than the list N22 corresponding to the number are erased. Memory 140
The erased data is stored as shown in FIG. 5(C).

Further, the supply timing of the paper P fed from the stacking unit 28a to the transfer unit is changed for each row by an integral multiple of the pitch Py, and the paper P on which a predetermined image of the second original G2 is fed is written. It is controlled to match the area En. Thereafter, the list corresponding to the specified number range is edited and copied in the same manner, and when it is determined in step 5T13 that all the copies have been completed, step 5T
14, the state of the color change flag is determined, and if this flag is on, step STI s
At , the setting state is restored to the current container 122 containing black toner, and the entire process is completed.

According to the above embodiment, the entry area En of the first document G1
Edit one image arranged in the second document G2 specified by the number 1! (composition) and can be formed on multiple sheets of paper. Therefore, since the same list item ([1st etc.)] can be automatically filled in on multiple copies, there is no need to prepare a seal etc. in advance or affix a seal. It's convenient.

In addition, the writing position of the second manuscript G2 on the first manuscript G1 can be changed freely, which is convenient.

Incidentally, in the above embodiment, the second document G2 is attached to the first document G1.
Although a case has been described in which the list items described in 2 are entered, the contents of the second manuscript G2 are not limited to this.

Further, in the above embodiment, the paper that has been copied once is supplied to the transfer unit again by the multiple copying unit 28, but for example, the paper that has been copied once is fed to the paper feed cassette without using the multi-LU1M copying unit 28. The paper may be stored in a cassette and fed from this cassette in synchronization with the editing/copying operation.

Furthermore, the photosensitive drum 10 applied to the above embodiment
is selenium (Se) based, and this photosensitive drum has high sensitivity to blue light. Therefore, Fig. 4 (b
