In step S17, the transfer corotron 72 is turned on. After turning on the transfer Flotron 72, the process proceeds to the next step S19. In step 519, it is determined whether or not manual copying is being performed. In other words, the recording paper 58 is fed manually rather than from the paper feed cassette 32. It will be determined whether the If it is manual feeding or copying, the process advances to the next step 521, where the solenoid of the cleaning device 88 that was turned on in the previous step Sll is turned off. If it is not manual feeding: copying, the process proceeds to step S23 without passing through step S21.

In the next step S23, the paper feeder is first turned on, the paper feed roller 66 starts rotating, and the paper 58 is completely conveyed toward the register roller 70. At the same time, the solenoid of the cleaning device 88 is turned off. The solenoid will be turned off twice in the case of manual copying in the previous step 7 step 519, that is, if it goes through step S21, but since only the off signal is supplied, the solenoid will not be turned off. There is no change in any part.After 200 msec has passed since the solenoid was turned off, the next step S2

28. It is determined whether the image is set to move to the right using the X key 130 and the Y key 132.
If the image has been set to move to the right, the process proceeds to step S29, and if the image has not been set to move to the right, the process proceeds to step S51.

In step S29, it is determined whether the copy is the first copy. If it is the first copy, the process advances to step S31; if it is not the first copy, that is, if it is the second or later copy, the process advances to step S45.

In Step 7 S31, after 300m5ec has elapsed, the original platen 1
In the zero-order step S33, in which a feed clutch (not shown) for scanning the original document table 14 is activated, it is determined whether the document table 14 is located at the image position. The image position, that is, the position of the document table at which the image of the document 40 starts to be formed as an electrostatic latent image on the photoreceptor drum 46 is determined. If the image position is reached, the counter counts the time from the home position to the image position in the next step S35°.If the image position is reached, the process advances to the next step 337.In step S37, the feed clutch is The return clutch of the document table 14 is turned on after 200 msec.

In this way, when right movement is set and the first copy is made, the time from the home position to the image position is unknown for the first copy, so the stacking table 14 must be moved before copying starts. You need to move and take your time.

Next, in step S39, it is determined whether the document table 14 has returned to the home position. If it returns to the home position, the process proceeds to the first step S41, and step S4
1, it is determined whether the time it takes to move the image 1 degree to the right is greater than the sum of the time counted in step S35 and 1020 msec. This 102
0 m sec is 200 m sec set in step S51, which will be described later, and 300 m sec after step S53.
sec, 100m5ec set in step S55
and 420 m5ec set in step 371. In other words, in order to move the image to the right, it is necessary to advance the feeding of the marking paper before the formation of the latent image, but the time allowed for this advance is the original starting time of paper feeding, that is, the registration in step 57.5. Determine whether it is longer than the time until the timing of Clutubon.

If the image movement time is greater than the sum of the value counted in the previous step 335 and 1020 msec, the registration clutch is activated in the next step S43, and after adjusting the timing 'J4 in step S44, the sled clutch is activated. Tsubu S
Proceed to step 49. If the determination in step S41 is NO, the process proceeds to step S47, and the time difference is set in a resist clutch on timer (not shown).In this way, the moving time is calculated as follows:
If it is shorter than 020102O, the time difference is stored in RAM.
This timer is set in a timer within the register, and counted by the interrupt routine described later. If the timer counts up, the resist clutch is turned on at that point.

On the other hand, if it is determined in the previous step S29 that it is not the first copy, the time (timing) to be measured in steps S31 to 841 has already been determined by the first bind-up copy. Therefore, in step S45, the 8 motion time of one image is the time counted in slap S35,
L: Determine whether 720 m sec is greater than 1[1]. This 720 m sec is the 1020 m sec in step S41 minus 300 m5 ec, which is the time required to change the direction of the document table 14, which can be set after step S53, and the feeding timing is earlier than the original paper feeding timing (in advance). This is the time when the resist clutch should be turned on. If the travel time is greater than the sum of the time counted in step S35 and 720 m5ec in step S45, the process proceeds to step S43, and if it is smaller, the process proceeds to the previous step S47.Therefore, it is determined as 'NO' in step S45. In other words, if the travel time is short, '' in the previous step S41 is
As in the case of "NO", it was decided that the subsequent timing would be determined by the interrupt routine.

In step S49, the LED play 48 is turned on so that all the LED IPs 50 are lit. That is, the microcomputer 134 provides a signal for "all lighting" to the LED array 48.

When moving the image to the right, in order to prevent the image on the left side of the document 40, for example, the image of the positioning plate 20, from being completely formed on the photoreceptor drum 46, that is, to erase unnecessary electrostatic latent images, The entire LED array 48 is turned on.

After that, in step 351, the light fi 42 for irradiating (exposing) the document 40 with light is turned on, and since the light source 42 starts up slowly, after a time of 200 m5ec, the next step, the knob S53, is proceeded to. At the knob S53, it is determined whether or not it is the first copy, as in the previous step S29. If it is the first copy, the rise of the light 7fI42 turned on in the previous step S51 is slow, so an additional 30
After the stabilization time of 0 m5ec has elapsed, the process advances to step S55.

In step S55, the charging corotron 48 is turned on and the feed clutch is turned on.

In the next step S57, it is determined whether the document table 14 has been fed to the image position. If the image position has not been reached, proceed to the first step S5
At step 9, the time from the home position to the image position is counted.

During continuous copying, the data counted in step S59 is used as image position data for moving the image to the right. If it is determined in step S57 that the image position has been reached, the process proceeds to the next step 561.

In step 561, the microcomputer 134
It is determined whether the trimming mode is set by looking at the signal from the mouse 36. If it is determined in step S61 that it is not the trimming mode, the next step S63
Then, the LED array 48 that was turned on in the previous step S49 is turned off or extinguished. If it is determined that the trimming mode is in effect, the process proceeds to step knob S65, while the LED array 48 remains on, that is, remains fully lit.

In step S67, the microcomputer 134
Look at No. 18 from mouse 36 to determine whether masking mode is set. If it is determined that the mode is masking mode, the process advances to the next step S69.

In step S69, the positions of the X coordinates of sides ab and cd for trimming or masking set using the mouse 36 are checked. Specifically, after the start of X coordinate detection is determined in an interrupt routine to be described later, detection is performed in the interrupt routine. Then, in step 571, the time until the document table 14 finishes feeding is counted, and after a time of 6420 m5ec, which corresponds to the normal paper feeding timing, has elapsed, the process proceeds to the next step S73.

In step 373, as in the previous step S27, it is determined whether the image moves to the right. If it moves to the right,
In the previous step 543, register 7 in 1.
Since the register roller 70 is being driven by the register roller 70, it is determined whether the register roller 70 is being driven and the process proceeds to step S77.

If it is determined that the image is not to be moved to the right, that is, if the image is to be moved to the left, the time for eight left movements is counted in the next step, step S74, and the registration clutch is activated in step S75. Turn on.

In step S77, when it is detected that the document table 14 has been fed to the return position, the next step S77 is performed.
79, the exposure light fA42 is turned off, and the LED array 48 turned on in step S49 is completely turned off.

In the subsequent step 581 (FIG. 16C), the microcomputer 134 checks the sheet number counter and determines whether or not continuous copying is being performed. If it is continuous copying, the paper feed sensor is turned off in the next step S83, and then the paper feed sensor is turned off in the previous step S2.
Return to 3. That is, for the second and subsequent copies, the process starts from step S23.

If it is determined in step S81 that it is not continuous copying, the process proceeds to step S85, and in the previous step S79, the return clutch is turned on or turned off. After that, the photoreceptor drum 4
After the electrostatic latent image on the recording paper 58 is completely transferred to the recording paper 58, for example, 200 m5ec, the charging corotron 72 is turned off. Then, the process advances to step S87, and step S87
Then, it is detected that the paper ejection sensor is turned on due to the ejection of the recording paper 58, and the process proceeds to the next step S89. Turn off motor 96. The copier then goes into standby mode.

Next, the interrupt routine of this embodiment will be explained with reference to FIG. This interrupt routine can be called at regular intervals by an internal timer of the microcomputer 134. This interrupt routine mainly determines the on timing of the registration clutch in the movement mode, and controls the lighting position and timing of the LED array 48 in the trimming or masking mode.

In the first step 5101, the macro computer 134 determines whether the document table 14 is at the home position, similar to step S13 in FIG. 16A. If it is not the home position, the process directly proceeds to step S105, but if it is in the home position, the return clutch is turned off in step 5103, and then the process proceeds to step S105.

In step S105, it is determined whether or not the paper feed sensor is on, that is, whether the recording paper 5
8 is conveyed. Then, when conveyance of the recording paper 58 is confirmed, the paper feed clutch is turned off in the next step S107. Then step S
If the preceding meal delivery sheet has been conveyed, the paper feed sensor is turned off, so the microcomputer 134 turns off the registration clutch in the next step 5109, and then proceeds to step S111.

In step S111, if the movement of the image to the right has been set by the counter 36, in step S47, the time difference between the movement time and the start timing of the electrostatic latent image is determined in RAM.
If the answer in step S111 is "YES", the microcomputer 134 proceeds to step S113 to determine whether the on-timer has timed out. After several interrupt routines, when the resist clutch on timer expires by 7', in step 5115, the microcomputer 134
turns on the resist clutch. That is, at this point, the paper feeding timing for moving the image to the right is determined.

In the next step S117, the microcomputer 134 determines whether the trimming mode or the masking mode has been set and the detection of the X coordinate for controlling the LED array 48 has started. This can be determined, for example, by setting a flag in step 569 (FIG. 14A) and by having the microcomputer 134 detect whether the flag is fully set.

When the start of X coordinate detection is determined, the next;
At step 19, the microcomputer 134 determines whether the left corner of the area to be trimmed or masked has reached below the partial erase ramp, i.e., iσ of the LED array 48. When the area to be trimmed or masked reaches this LED array 48, the microcomputer 134 lights up all the LED elements 50 outside the area in the trimming mode and inside the area in the masking mode. A signal is given to the LED array 48 to light up all the LED elements 50 of the LED array 48 . Thereby, step S12
In 3, L required for trimming or masking
The LEDs 50 of the ED array 48 can be partially turned on selectively.

If it is determined “NO” in step S119, the microcomputer 134 performs the following step S1.
At 21 it is determined whether the right corner of the area to be trimmed or masked has reached directly below the LED array 48 7 and upon detecting this at step S 121 the process proceeds to the next step 5125 .

In step 5125, the microcomputer 134 determines whether the mode is trimming mode or masking mode. If it is trimming mode, step 5127
Then, all the LED elements 50 of the LED array 48 are turned on. Conversely, if the masking mode is selected, the L partially lit in step 5123
All the LED elements 50 of the ED array 4B are turned off. After these two steps 5127 or step S129 have been executed, the microcomputer 134 completes the detection of the XFIA mark in step S131.

In the subsequent step 5133, the microcomputer 134 determines whether or not the counting of the positions at which the document table 14 should be returned, which was started in the previous step 571, has started. Then, in step 5135, the length of the document in the moving direction of the document table (including the margin) is determined.
The time required to feed the document table 14 is counted, and it is determined whether the document table 14 has reached the position where it should be fed. If it is determined in this step S135 that "-YES", the microcomputer 134 turns off the feed clutch in the next step 5137, and at the same time, in the next step 513
At step 9, the feed position is completed.

In subsequent step S141, the 71° computer 134, based on the signal from the mouse 36,
If the leftward movement mode of the image is set, in the next step 5143, the LED array 48 is fully turned on in order to erase unnecessary static latent images due to the leftward movement, and at the same time, in step S145 At this point, the charging Flotron 47 (Fig. 2) is turned off, and then the photosensitive drum 4 is turned off.
Prevent charging to 6φ, Sdep S 14
After step 5 is executed, the process returns to the routines shown in FIGS. 16A to 16C, as in the case where "No" was determined in steps 5133 and 5135, respectively.

In this way, according to the above-described embodiment, in the trimming mode or the masking mode, the lighting area or range of the LED array (partial light-slump) 48 is controlled in accordance with the area set by the mouse 36. Also,
When the movement mode is set, the microcomputer 13
4 controls the deviation between the image position and the paper feeding timing according to the movement of the paper, based on the position data input from the mouse 36.

(I.) Effect of the invention According to this invention, there is no position for editing on the manuscript table.
