In this embodiment, the area consists of 12×8 keys, and one key indicates an area of 40mm×40mm. When editing an image, this l block can be specified as the minimum unit.

Also, when data is written, it is written into one block. The document matching corner 2200 moves according to the size of the document, making it easier to see the correspondence between the positions on the document and the positions of the keys.

Placing the original on the panel and specifying the imprinting position makes it easier to understand and specify the imprinting result.

FIG. 1 shows the meaning of each key when the area designation keys 2001 to 2096 are changed to input keys for alphabets, numbers, and symbols in order to input arbitrary data when it is desired to write the data. The display of each key may be written thinly on the surface of the editor in advance, or a transparent film or the like with the above-mentioned alphabets written thereon may be placed over the editor only when data is input. Alternatively, the entire display may be a graphic liquid crystal, with a transparent sensor mounted on the surface, and the display contents of the liquid crystal may be switched between FIG. 1 and FIG. 16. Alternatively, there is also a method in which two display contents for one block are printed in advance on a sheet or the like, and only the selected display is illuminated with a backlight such as an LED. Alternatively, the display of each block may be rotated, and by switching the display, the mode may be switched as shown in FIGS. 1 and 16.

The table below shows what kind of information is communicated as write data from the third CPU to the first CPU in the example of FIG. 12. Data 1 indicates LED lighting. (The latent image is erased and is not developed.) Data 0 is LED
Indicates off. (It will remain as a latent image and will be developed.) The following margins, and when negative/positive inversion is specified, the data of the image valid LED (LED numbers 5 to 35 in the above example) are 0 and 1.
All you have to do is reverse it. (Invalid LED (LED number I~4
．． 36 to 40) are always lit for erasing. ) FIG. 17 shows the configuration of the third CPU that controls the editor 2000. Here, ICI to ICl0 are input/output expansion rcs such as Intel's 8243, to which various keys 2001 to 2096.2Ill to 2128 and various displays 2111a to 2128a are connected. Also, ICI

3, initialization of the first CPU such as setting of various registers, and initial settings for setting the device to the initial mode are performed (step St).

Next, an internal timer built in the first CPU and whose value is set in advance as an initial setting is started (step S2).

Next, the subroutines (steps S3 to S8) shown in the flowchart are sequentially called.

Here, the head control routine (step S3)
is a routine for controlling the position of the LED head 1251. LED array control routine (step S
4) is a routine for controlling lighting of the LED array 1252. The liquid crystal shutter control routine (step S5) is a routine for controlling opening and closing of the liquid crystal shutter 210. Inter-image eraser control routine (
Step S6) is a routine for controlling the inter-image eraser 200. The copy operation routine (step S?) is
This is a routine that performs copying.

When all subroutine processing is completed, wait for the end of the internal timer that was set first (step 5IO),
1 routine ends. The length of one routine is used to count the various timers that appear in the subroutine. (The various timer values determine the end of the timer based on how many times this l routine has been counted.) Also, after calling all subroutines, the first CPTJ performs data communication with other CPUs (step S9).

FIG. 19 shows the head control routine (step S
3) is shown. When the power is turned ON (step S2+)
, in order to return the LED head 1251 to its normal position, the motor is rotated until the switch I254 is turned on (step 522). Next, when the data write signal becomes 1 (step 523), if the position (coordinates) to write that data is 1-12 (see Figure 16), the head position can remain as it is, so move the head. is 0. 12
~24, the writing position is the next block in one row, so it moves 40 mm. Below, for 25-36, 80mm
etc., by the amount shown in the table shown in the flowchart (step 524).

FIG. 20 shows the LED array control routine (step S4). Optical system! 0 scanner is 5W53 (
When the image leading edge SW) is turned on (step 541), the timer M1 is started (step 542). This timer is a timer from the leading edge of the image to the area where data is written by the LED head 1250. For example, if writing area "4" is specified, the timer until the writing start position is 40n + mXa ÷ scan speed (40
mm: length of I block).

At the end of timer Ml (speed 543), timer E
(Step 5=14). When this timer E ends, a timer interrupt occurs, and editor 2
000 write routine starts. The value of timer E is the lighting time per data of each LED of the LED head. In this example, the width of one LED is 1mm+, so the lighting time of the LED is 1ffl111 on the drum.
The time for 1mm/drum speed is the timer E.
The value is . As a result, when one LED of the LED array lights up one unit, a square pattern of 1 mm x 1 mm is erased. Further, when the data end flag indicating that data writing is completed becomes 1 from the timer interrupt routine (FIG. 21) (step 545),
Since the data for 40 m+ minutes has been written, the flag is set to 0 (step 846) and all the LEDs are turned off (
step 547).

FIG. 21 shows an internal interrupt routine executed when timer E finishes timing. When timer E finishes counting, an internal interrupt is generated and the LED head 125
Each of the LEDs numbered 1 to 40 in FIG. 2 is controlled by write data sent from the third CPU. That is, L.E.
The light emitting diodes (numbers l to 40) of the D array 1252 are caused to emit light according to the imprint data (step S I
81). If the imprint data at this time is not the final data (step 51B2), set the timer E (step 9183), and if the imprint data is the final data, set the data end flag to "B" (step 51).
84). If the internal timer E is not set, this interrupt will not occur, so when the data end flag becomes "B", this interrupt processing ends.

FIG. 22 shows the liquid crystal shutter control routine (step S5). The timer Ll moves the LCD shutter 2 from the leading edge of the image to the pre-designated data writing position.
It is a timer for turning on 10 (closing the optical path),
Timer L2 is a timer that controls the ON time of the liquid crystal timer.

When the data write signal is 1 (step 561), if the coordinates to write data are I to 12 (step 562), the liquid crystal 210a is turned on (step 866), and if it is 13 to 24 (step 572), the liquid crystal 210b is turned on. ONt.

(Step 576), and the following processes are performed in the same manner, 85 to 96
In that case, 210h is turned on. The timing to turn it on is after the image tip switch is turned on (step 563).
, when the timer Ll up to the coordinate position in the middle direction ends (steps S64, 565), it is turned on (step 5
66). The specific timer value is determined by 40mm÷scan speed x (W-1) (W is the width of each part of the liquid crystal
10a, 210b, . . . ). That is, if the coordinate is 1, it is W-1-0, so the image leading edge SW is ON, and the liquid crystal 210a is immediately turned ON. Also, ONL, then timer L
2 starts (step 567), 40 mm (4
0mm ÷ scan speed) has passed (speed 86
8) Turn off the liquid crystal 210a (86 steps).

Below, other columns (columns 13-24,..., 85-
The same idea applies to column 96).

FIG. 23 shows a control routine for the inter-image eraser 200. When the scanner of the optical system 10 turns on the erase 5W52 (step 591), the inter-image eraser 200 turns 0FFL (step 592), and turns on at the end of scanning (step 593) (step S94). That is, it is turned off while there is a latent image on the drum.

The timer TA is a timer for controlling the paper feed roller clutch for 08 hours, and the timer TB is a timer for controlling the scan start.

Next, if the A paper feed section 20 is selected (step 51
03), the clutch of the A paper feed section 20 is operated (step 5104), and if the B paper feed section 22 is selected (step 5104), the clutch of the B paper feed section 22 is operated (step 5106).

Next, it is determined that the timer TA has ended (step 5ill), and the paper feed clutch is turned off (step 511).

Next, it is determined whether the timer T-B has ended (step 51).
2t), the scan motor M3 is turned on to start the scan operation (step 5122).

Incidentally, when the timer TH ends, an internal interrupt routine (FIG. 21) is executed, and data is passed on. Next, when a timing signal is output during the scan operation (step SI 31), a process of turning on the timing roller-clutch CL3 and setting the timing TC is executed (step SI 32).

Timing TC is a timing roller-controlled timer. A timing roller 35 transports the copy sheet onto the photoreceptor drum 10 in synchronization with the image.

Next, the end of timing TC is determined (step 5
141), turn off the charging, scan motor, and timing roller clutch (step 5142).
. Note that the timer TC may be set variably depending on the size of the copy sheet used.

Next, along with the return operation (step 5151),
When the optical system returns to the home position and the home position switch is turned on (step 5152), the developing motor M2. A process of turning off each transfer charger 14 and setting a timer TD is executed (step 5153). Timer TD is an auto-shut timer.

Next, step 516 determines whether the timer T-D has ended.

Initialization of the 30th PU, such as clearing and setting of various registers, and initial settings to put the device into the initial mode are performed (step 9201).

Next, an internal timer built in the third CPU and whose value has been set in advance as an initial setting is started (step 5202). Next, subroutines (steps 5203 to 8206) for editing area designation, write area designation, write data memory, and other processes shown in the flowchart are called in sequence. When all subroutine processing is completed, wait for the end of the internal timer that was set first (step S207),

(The various timer values determine the end of the timer based on how many times this l routine has been counted.) Data communication with the first CPU is controlled by an interrupt request from the first CPU (step 5211). The interrupt routine (FIG. 25(b)) is used instead.
