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 on it may be placed over the editor only when data is to be manually edited. 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.

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

Next, an internal timer built in the first CPLI 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 S7) is as follows:
This is a routine that performs copying.

When all subroutine processing is completed, wait for the end of the internal timer set first (step 5IO),
End the I routine. The length of time of this l routine is used to count various timers that appear in the subroutine. (The various timer values determine whether the timer ends based on how many times this l routine has been counted.)

Move n. Thereafter, when it is 25 to 36, it moves by the amount shown in the table shown in the flowchart, such as 80 mm (step 524).

FIG. 20 shows the LED array control routine (step S4). The optical system IO scanner is 5W53 (
When the image leading edge SW) is turned on (step S41), start the timer M1 (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 distance to the writing start position is 40 mm x 3 ÷ scan speed (40 m
m: length of I block).

At the end of timer Ml (speed S = 13), timer E is started (step 544). Upon expiration of timer E, a timer interrupt is activated and the writing routine of editor 2000 is started. Timer E
The value of each LED of the LED head is ! This is the lighting time per data. In this example, the width of one LED is 1 mm.
Therefore, the value of timer E is the time when the LED lighting time is 1 mm on the drum, that is, 1 mm/drum speed. This results in one LED of the LED array) < 1
When the unit is turned on, a square pattern of lmmXlmm is erased. Also, the timer interrupt routine (
21), when the data end flag indicating that data writing is completed becomes 1 (step 545), 4
Since the data for 0 mm has been written, the flag is set to 0 (step 846) and all the LEDs are turned off (step 547).

FIG. 21 shows the internal interrupt routine that is 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 1 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 5182), set the timer E (step 5I83); 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 coordinate to write data is t-12 (step 562), the liquid crystal 210a is 0NL (step 866), and if it is 13 to 24 (step 572), 210b h <ON switch (step 876), the same process is performed, and if 85 to 96, 2

. The specific timer value is determined by 40mm÷scan speed x (IJJ-1) (W is the width of each part of the liquid crystal
0a, 210b, etc.). That is, if the coordinate is l, it is W-1-0, so the image tip SW is turned on and the liquid crystal 21 is immediately turned on.
0a turns ON. Also, when it is turned on, timer L2 starts next (step 567), and the timer L2 starts for 40mm (40mm

The liquid crystal 210a is turned off (step 569). below,
The same idea applies to the other columns (columns 13-24, . . . , columns 85-96).

FIG. 23 shows a control routine for the inter-image eraser 200. When the scanner of the optical system IO turns on the erase SW 52 (step 591), the inter-image eraser 200 is turned on at 0FPL (step 592) and at the end of scanning (step 593) (step 594). That is, it is turned off while there is a latent image on the drum.

Incidentally, when the timer TH ends, an internal interrupt routine (FIG. 21) is executed, and data is transferred. Next, when a timing signal is output during the scan operation (step S+31), a process of turning on the timing roller-clutch CL3 and setting the timing TC is executed (step 5I32). Timing TC is a timing roller-controlled timer. A timing roller 35 transports the copy sheet onto the photoreceptor drum IO in synchronization with the image.

Next, the end of timing TC is determined (step 5
