In FIGS. 20 and 21, a guide shaft 130 is provided in the first carriage 411 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 that allows the erasing range of the document to be set. Spotlight IT as a means of giving instructions
! 131 is movably provided. As shown in FIG. 21, this spot light source 131 consists of 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 light emitting element 132 is transmitted through the lens. 133 directly onto the document table 2! ! Spora becomes d] - It is irradiated as light. 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.

Further, the spot light source 131 is connected to a timing belt (toothed belt) 134 disposed along the guide shaft 130. The timing belt 134 is connected to a boot IJ 136 provided on the rotating shaft of the pulse motor 135 and a driven 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.

will be moved while the is lit. That is, the operation key 30b,
When 30d is pressed, the motor 33 is driven, and the first carriage 41 plate and the spot light source 131 are moved in the scanning direction (the 22nd
(in the arrow y direction shown in the figure). In addition, operation key 3
When 0a and 30c are pressed, the motor 135 is driven and the spot light WA131 is moved in a direction perpendicular to the scanning direction (direction of arrow X shown in FIG. 22).

The operator operates the operation keys 30a to 30d while visually viewing the spotlight transmitted through the document G, and presses the position designation key 308 after moving the spotlight to point S1 on the document G shown in FIG. 23, for example. Then, this 81T: designated coordinate position is stored in the main processor group 71 shown in FIG. Similarly, when the position designation key 30e is pressed with the spotlight moved to 82 points on the document G, 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. 24, 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. 25 and 26, this erasing array 150 has a plurality of light shielding cells 151 arranged in a direction perpendicular to the rotational direction of the photoreceptor drum 10, and each light shielding cell 151 has a plurality of light shielding cells 151 arranged therein. A light emitting element 152 made of, for example, a light emitting diode as shown in FIGS. 27<a> and (b) is provided. Further, a lens 153 is provided in the opening of each cell 151 facing the photoreceptor drum "10" to focus the light from the light emitting element 152 onto the surface of the photoreceptor drum 10. The number of light emitting elements is matched, for example, with the capacity of the memory 140 in the column direction.Here, if the distance between the light emitting elements 152 is P and the number is N, the total length of the erase array 150 is Q-NXP. becomes.

The erase array 150 is driven by the array driver 160 described above. As shown in FIG. 28, 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 that holds the contents of this shift register 161, and a switch circuit 164 consisting of a plurality of switch elements 163 that are turned on and off by each output signal of this store register 162, and these switches The movable contact piece 163a of the element 163 is grounded, and the fixed contact 163b is connected to each cathode of the light emitting element 152 constituting the erasing array 150. The anode of each of these light emitting elements 152 is connected to the power supply VCC through 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 the erase range preset in the main processor group 71, and the memory 140 has a high level signal '°1'' in the erase range.
, a low level signal ITO+1 is stored in the other parts. That is, in this memory 140, for example, the capacitance in each column direction is the same as that of the light emitting elements 152 constituting the erasing array 150.
It is made up of RAM matched to the number of.

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.
40, data for one column is sequentially read out in the row direction (shown in FIG. 29). 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 photoreceptor drum 10 reaches the erasing array 150, the main processor group 71 outputs a latch signal L, and in response to this signal, Data stored in shift register 161 is supplied to store register 162.

That is, since the erasing array 150 is disposed between the charger 11 and the exposure section Ph, one row of data output from the memory 140 is stored at an angle of, for example, θl between the erasing array 150 and the exposure section ph. Assuming that the photosensitive drum 10 is rotating at each speed, the output timing of TH is controlled by a latch signal so that it is supplied to the store register 162 from θ1/ω.

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 exposed afterwards, no electrostatic latent image is 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.

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 required position of the first original document. FIG. 2(a) shows a first document G1, and a part of the first document G1 is provided with an entry area En for list items ([i, @, etc.). Further, FIG. 2cb> shows the second original G2. This second manuscript G2
For example, in the row direction and column direction, [phase], III, @, [,
List items such as are arranged. The arrangement pitch of these list items is, for example, PX in the row direction and Py in the column direction, and for each document, list items of pxxn in the row direction and PyxmfI in the column direction are arranged. 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
For example, the pitch Py in the column direction is set to 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, for example, the pitch Py of the first carriage 4.
11 is set to an integral multiple of the drive pitch of the pulse motor 33 that drives the pulse motor 11.

Set 2. For example, when copying the list item N11 ([phase]) into the entry area En, the first document G1 and the second document G2 are placed at the same height as shown in FIG. 4(a). Set. In addition, list item N41 (
When copying [IU: ko) into the writing area Em, as shown in FIG. 4(b), the first original G1 and the second original G2 are
are set at different height positions (ST1).

In this state, when the write position designation key 30f is operated (ST2), the main program II is set to the flap group 71 (edit copy mode (composition mode)), and the operation shown in FIG. 1 is performed.

That is, first, in step ST3, the spotlight w131 is turned on, and this spot light source 131 is moved to the center En' of the entry area En for the list items stored in the main processor group 71 in advance, and the first The center part En of the writing area En is
' is displayed. In this case, the center En' of the entry area En and the second [H1! It corresponds to the center point φ (see FIG. 2<b)) in the list frame (St) of G2.

Thereafter, in step ST4, it is determined whether the operation keys 30a to 30d for moving the spot light source have been operated. As a result, if the operation keys 308 to 30d are operated, the spot light source 131 is turned on as described above in step ST5, and is moved according to the operation of the operation keys 30a to 30d, as shown in FIG.

When the position designation key 30e is operated at a desired position, the entry area En corresponding to that position, that is, the center 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 ST3, the operation key 308
If ~30d is not operated, llIII is moved to step ST6. In this step S76, it is determined whether the list designation key 30h has been operated. As a result, when the list designation key 30h is operated, the spot light source 131 is moved to the left column of the second document G2 stored in the main processor group 71 in advance, that is, to the center point φ' of the list item Nxx. , the list item Nil is displayed on the list item N11 of the second document G1 by transmitted light.
The center point φ− of is displayed. After that, in step ST7, the operation keys 30d and 30 for moving the spot light source 131 are
It is determined whether or not b has been operated.

As a result, when the operation keys 30d and 30b are operated, the spot light source 131 is turned on in the Stellaf S-8 as described above as shown in FIG.
According to the operations of 0d and 30b, it is moved in the y direction by Py pitch.

When the position designation key 30e is operated at a desired position, the list item Nxy corresponding to that position, that is, the center point φ' is stored in the main processor group 71. After the operation for changing the list item Nxy is completed in this way, or in step ST7, the operation key 30 is
If d and 30b are not operated, υ1 transfer is performed to step ST9.

In step ST9, it is determined whether or not the color change key 30g has been operated. As a result, color change key 30Q
is being operated, in step 5T10,
If the color change flag is set and the color change key 3C1 is not operated, the system moves to step ST7. In this step 5T11, it is determined whether or not the copy key 30t has been operated. As a result, the copy key 301
is operated, in step 5T12, the first
The carriage 411 is moved in the range from Ya to Yb shown in FIG. 3, and the first original G1 is copied in the normal manner by the operation described above.

Then, the sheet on which the image of the first original G1 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, the control starts at step 5T13.
will be moved to In this step 5T13, the state of the color change flag is determined, and if this flag is on, the process proceeds from the developing device 122 containing black toner to the developing device 122 containing red toner in step 5T14. 121. After this, the control goes to step 5T15.
will be moved to In this step 5T15, the second document G2 is exposed and scanned by the first carriage 411, and the erasing array 150 is operated so that the writing area En of the paper sheet to be supplied from the accumulating section 28a to the transfer section again is marked. List item NXV specified in document G2 of No. 2 is copied.

That is, first, the first carriage 411 is moved in the range from Yb to YC shown in FIG. 3, and the second original G2 is exposed and scanned. At this time, the image of the list item Nll in the second document G2 shown in FIG. 2<b) is formed on the first sheet.

In other words, the memory 140 includes the main processor group 71.
Under this control, as shown in FIG. 6, a low level signal is stored in the storage area corresponding to the list item Nll of the second document G2, and a high level signal is stored in the storage area other than the list item N11.

The data stored in this memory 140 is read out in synchronization with the operation of the first carriage 415, 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 m
Only the image corresponding to list item Nir of G2 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, this paper contains Figure 7 (
As shown in b), the image (
[phase]) is formed. This image shows the color change key 30
When g is operated, red toner is used, and when color change key 3C1 is not operated, black toner is used. In this way, the first original G1 and the second original
The paper P on which the image of the original G2 has been edited and copied is discharged to the tray 25 in step ST'16.

Thereafter, in step 5T17, 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 ST15, and editing and copying is performed as described above.

Further, the supply timing of the paper idP fed from the stacking unit 28a to the transfer unit is changed for each column by an integer multiple of the pitch Py, and the paper P to which a predetermined image of the second original G2 is fed is written. It is controlled to match the area En. below,
Similarly, editing and copying of the list corresponding to the selected range is performed, and when it is determined in step 17 that all the copies have been completed, the state of the previous color scheme change flag is determined in step 5T18, If this flag is on, in step 5T19, the setting state is restored to the developer 122 containing black toner, and the preprocessing is completed.

Further, in the same way that the image of the list item Nil is copied to the entry area En, the image of the list item N41 is copied to the entry area Em.

According to the above embodiment, it is possible to edit and synthesize one image of the second original fiG2 selected by parallel movement of the spot light source into the writing area of the first original 1iGx and form it on a plurality of sheets. It is said that therefore,? ! Since the same list item ([1st etc.)] can be automatically entered on the number of copies, there is no need to prepare a seal in advance or affix a seal, which is extremely convenient in practice. .

Also, the entry position in the first manuscript G1 and the second manuscript G
The positions on both sides to be combined in 2 are parallel, and the image is selected by parallel movement of the spot light source, so it moves along the photoreceptor drum and changes the imaging position of the image on the photoreceptor drum. In other words, the above synthesis can be performed without using means for moving the lens, and can be realized with a simple configuration. That is, since the second document is moved instead of moving the lens block, a mechanism for moving the lens block (in the x direction) is not required.

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 fed to the transfer section again by the multiple copying unit l-28, but for example, the paper that has been copied once is fed to the transfer unit without using the multiple 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. 2 (b
) Each list (image) of the second manuscript G2 shown in Ni! −
If the frame St that partitions Nn3 and the list number are formed using blue ink, even if the set position of the second document G2 is slightly shifted from the document table 2,
It is possible to prevent the frame St from appearing on the image formed on the paper.

Furthermore, the arrangement position of the erasing array 150 is not limited to that shown in FIG. 24, but as shown in FIG.
21, and the formed electrostatic latent image can be erased according to a designation.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to form an image on a transfer material by combining at least one image on one original with a predetermined range of one original, and furthermore, it is possible to form an image on a transfer material. It is possible to perform the above-mentioned synthesis without using a changing means that moves along the carrier to change the imaging position of the image on the image carrier, and it is possible to provide an image forming apparatus that can be realized with a simple configuration.
