Abstract

PURPOSE:To assign position for editing by simple operation by providing a position assigning means for assigning the position of an original to be edited by moving on the original. CONSTITUTION:A mouth 36 that makes position assignment for edition is connected to the body 12 by an elastic cord 28. The mouth 36 is moved on an original 40 placed on an original platen 14 with the original face facing upward as shown by solid lines and position assignment is made for edition. The original 40 for which position assignment is completed is turned over to make the face of the original to be copied face downward and placed again on a transparent glass plate 16 as shown by dotted lines. At the time of a start key 28 is operated, an edited copied picture image is recorded on a transfer paper supplied from a paper feed cassette 32. Thus, as position assignment for edition can be made on the original platen, an apparatus exclusively used for edition such as an editor, etc., is not necessary.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an electronic copying machine with an editing function, and in particular, it forms an electrostatic latent image on a photoreceptor using reflected light from scanning a document to perform image editing such as trimming. Regarding electronic copying machines.

(Prior Art) There are two known types of copying machines that can perform image editing. The first method is to place the original on an editor for image editing, specify positions such as trimming and masking using an input pen, and then transfer the original to the original table and perform the copying process. be.

In the second method, the original is placed face up on the original platen, a transparent sheet with coordinates is placed on top of it, the coordinates of the original are known through the transparent sheet, the coordinates are entered manually, and the original is then read. The copying process is performed by turning the paper upside down.

(Problems to be Solved by the Invention) The first prior art requires a special editing device such as an editor for editing, which makes the device expensive and requires a large space to install the device. needed space.

In the second conventional technique, the editing position is specified by reading the coordinates of the document and using keys, which makes the operation very complicated.

Therefore, the main object of the present invention is to provide an inexpensive and compact electronic copying machine with an editing function, which allows editing positions to be specified with a simple operation.

(Means for solving the problem) To put it simply, the present invention includes a manuscript table for placing a manuscript, and a position of the manuscript to be edited by moving the manuscript placed on the manuscript table. This is an electronic copying machine with an editing function, which includes a position specifying means for copying a document, and an image forming means for forming a copy image based on the amount of movement of the position specifying means when copying a document.

(Operation) The document is placed, for example, facing upward, on the document table so that the surface of the document can be viewed visually. By moving the position specifying means on the surface of the document, the position of the document to be edited, for example, a portion of the document surface to be trimmed, is specified. That is, the position specifying means generates movement amount data or position data according to the movement amount by moving on the document. Thereafter, if necessary, if the original is placed with its surface facing upward, the original is turned over and placed so that the surface of the original to be copied faces downward. When the copy button is operated, the image forming means forms a copy image that is edited (trimmed, centered, etc.) based on the position data from the position specifying means.

(Effects of the Invention) According to the present invention, a position for editing can be specified on the document table, so unlike the first prior art described above, a dedicated editing device such as an editor is not required.

Furthermore, according to the present invention, the position of the document to be edited can be specified simply by manually operating the position specifying means and moving it over the document. , its positioning is very easy to operate.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 is an overall external view of an electronic copying machine according to an embodiment of the present invention. The electronic copying machine 10 includes a main body 12.
A document table 14 is provided on the upper surface of the document document 2 . This manuscript metalwork 4 is supported by the main body 12 so as to be movable left and right. The document table 14 includes, for example, a transparent glass plate 16,

A positioning plate 20 for positioning the placed original is provided along three sides of the document. Furthermore, L-shaped magnetic tape 22 is attached to two sides of this U-shaped positioning plate 20. This magnetic tape 22 is used to generate a reference point signal to a magnetic sensor of a mouse 36, which will be described later, when editing a manuscript.

An operation panel 24 is formed in front of the top surface of the main body 12. A group of keys 26, a start key 28, and a display panel 30 are formed on this operation panel 24. The key group 26 is used, for example, to set the number of copies. The start key 28 is used to issue a copy start command. The display panel 30 displays the desired number of copies set by the key group 26 and the status of the copying machine, such as "Ready to copy".

A paper feed section for removably mounting a paper feed cassette 32 is formed at one end of the main body 12, and a paper discharge section including a paper discharge tray 34 is formed at the other end.

Furthermore, the mouse 36 for specifying the position for editing is
It is connected to the main body 12 by an elastic cord 38 of the book.

In other words, the document surface is facing upward as shown by the solid line on the document table 14! ! The user moves the mouse 36 over the original document 40 placed in the second position to designate a position for editing. Then, the original 40 whose position for editing has been specified using the mouse 36 is turned over so that the original surface to be copied faces downward, and is placed again on the transparent glass plate 16 as shown by the dotted line.

Thereafter, when the start key 28 is operated after the document cover 18 is closed, the edited copy image is recorded on the transfer paper supplied from the paper feed cassette 32 and is ejected onto the paper ejection tray 34.

Next, the internal structure of the electronic copying machine 10 will be described in detail with reference to FIG. As described above, the document table 14 including the transparent glass plate 16 and the document cover 18 are attached to the upper surface of the main body 12 so as to be openable and closable. A slit is formed on the upper surface of this main body 12, that is, below the transparent glass plate 16. In connection with this slit, a light source 42, for example a halogen lamp, is fixedly provided in the body 12. Associated with the light source 42 is a reflective mirror with an elliptical cross section. The light from the light source 42 is reflected by the reflecting mirror and irradiated onto the document placed on the transparent glass plate 16. Therefore, as the document table 14 is moved in the direction of the arrow, the document receives and reflects the light from the light source 42 through the aforementioned slit. The reflected light from the original, that is, the original image, is projected onto the photoreceptor drum 46 and formed into an image through a short focus lens array 44 fixedly provided below the slit. This short focus lens array 44 is
It consists of a focusing photoconductor with a large number of Rondo lenses arranged closely together. Note that it goes without saying that such a short focus lens array 44 may be replaced with another plastic lens array or a convex lens.

A photoreceptor drum 46 is arranged approximately in the center of the main body 12,
It is rotated in the direction of the arrow (clockwise) by a drive source (not shown) in synchronization with the movement of the document table I4. The photosensitive drum 4G includes a conductive substrate and a photoconductive layer formed of amorphous silicon or the like laminated thereon.

A developing device 56 is provided downstream of the LED array 48 for developing the electrostatic latent image with toner. This developing device 56 stores a mixture of toner and carrier. This mixture is transferred by a magnetic roller 57.
It is flown toward the photosensitive drum 46. At this time, spikes of the mixture are formed on the portion of the magnet roller 57 that faces the photosensitive drum 46. When the spikes come into contact with the photoreceptor drum 46, the negatively charged toner adheres to the electrostatic latent image formed by the positively charged toner. In this way, the electrostatic latent image formed on the photoreceptor drum 46 is developed as a toner image by the developing device 56.

Recording sheets 58 are stored in a stacked manner in a paper feed cassette 32 that is removably attached to one end of the main body 12 . At the bottom of the paper feed cassette 32, a support plate 60 for placing the recording paper 58 thereon is provided so as to be swingable in the vertical direction. An opening 62 is formed in the lower part of the support plate 60. A free end of a push-up lever 64 whose base end is swingably attached to the inner bottom of the main body 12 is inserted into the opening 62 . A spring (not shown) is provided in association with the push-up lever 64 to bias the push-up lever 64 clockwise. The support plate 60 is pushed upward by the push-up lever 64. Therefore, the recording sheets 58 stacked in the sheet feeding cassette 32 are pushed up by the push-up lever 64, and the uppermost recording sheet 58 comes into contact with the sheet feeding roller 66 and is taken in. In addition,
If necessary, a paper size detector 68 is provided in association with the paper feed cassette 32.

A register roller 70 is provided behind the paper feed roller 66. The recording paper fed from the paper feed cassette 32 is temporarily stopped by the register roller 70, and then fed in the direction of the photosensitive drum 46 in synchronization with the movement of the document table 14.

This separating corotron 74 is used to prevent the recording paper 58 on which the toner image formed on the photoreceptor drum 46 has been transferred from being attracted by the residual charge on the photoreceptor drum 46 . 58 is subjected to an alternating current corona discharge to neutralize its charge.

A vacuum conveyor 76 is provided downstream of the separating corotron 74 for conveying the recording paper 58 to which the toner image has been transferred. The recording paper 58 is conveyed toward the fixing device 78 by the vacuum conveyor 76 .

The fixing device 78 includes a heating roller 82 with a built-in heater 80;
and a pressure roller 84 that is pressed against a heating roller 82. The recording paper 58 on which the toner image has been transferred is inserted between the heating roller 82 and the pressure roller 84, thereby being heated and pressurized to fix the toner image. A paper discharge roller 86 is provided downstream of the fixing device 78 for discharging the recording paper 58 after fixing onto a paper discharge tray.

A cleaning device 88 is provided above the vacuum conveyor 76 and near the circumferential side of the photoreceptor drum 46 . This cleaning device 88 cleans the recording paper 5.
Toner remaining on the photoreceptor drum 46 without being transferred to the toner 8 is removed. This cleaning device 88
includes a blade 90 for scraping off residual toner on the photoreceptor drum 46 and a screw conveyor 94 for conveying the toner scraped off by the blade 90 to a waste toner container 92.

A main motor 96 is provided above the above-mentioned fixing device 78 to drive the document table 14, the photosensitive drum 46, the vacuum conveyor 76, etc. with a belt via a clutch.

A control section 98 is provided on the left side of the main motor 96 to control the operation of the entire copying machine.

This control section 98 houses various components necessary for a control system as shown in FIG. 8, which will be described later.

Here, this LED array 48 will be explained with reference to FIGS. 3 and 4. The LED array 48 includes, for example, 64 LED elements 50.50, as shown in FIG.

LED elements 50, 50. ...is driver ■C5
The lighting is controlled by pulses supplied to the two input terminals SIN, CLOCK and LATCH. the desired LE to remove the charge on that portion of the photoreceptor drum 46.
When lighting the D element 50, select the LE to be lit.
A control pulse is applied from the input terminal SIN of the driver IC 52 in synchronization with the clock pulse so that the output terminal of the driver IC 52 to which the D element 50 is connected becomes low level. Then, when a launch pulse is supplied from the input terminal LATCH, the driver IC to which the LED element 50 to be lit is connected
Since the output terminal 52 is held at a low level, the LED element 50 remains lit.

To light up all 64 LED elements 50, all 64 control pulses supplied from the input terminal SIN may be set to low level, and all of the control pulses may be held at low level by the latch pulse.

Further, during masking, which will be described later, the LED elements 50 between two points to be masked are lit for a predetermined period of time, and during trimming, the LED elements 50 only between the two points are turned off, and the LED elements 50 outside are lit. become.

Incidentally, such lighting/extinguishing of the LED elements 50 is controlled by converting the Y coordinate data obtained by the aforementioned mouse 36 (FIG. 1) into position data of the 64 LED elements.

Next, referring to FIG. 5, the mouse 36 connected to the main body 12 by an elastic cord 38 will be described. The mouse 36 is a box-shaped case 10 that can be held or operated with one hand.
0, and necessary parts are housed within this case 100.

A part of the side protrusion of the case 100 has a hole 102 for viewing the magnetic tape 22 (FIG. 1) from above.
is provided. Also, inside the case 100, a magnetic sensor 104 for detecting the magnetism of the magnetic tape 22 is provided.
is provided. The signal from this magnetic sensor 104 is used as a reference point signal. Furthermore, a rotary encoder 106 is provided inside the case 100. As shown in FIG. 6, the rotary encoder 106 has a built-in slit disk 110 fixed to the rotating shaft 108. A light emitting element 112 for emitting light and a light receiving element 114 for receiving light from the light emitting element 112 through the slit are provided on both sides of the slit disk 110.

A rubber roller 116 whose circumferential surface partially protrudes from the lower surface of the case 100 is fixed to the rotating wheel 108 of the rotary encoder 106 . The rubber roller 116 is rolled over the original 40 during editing, and provides rotation to the slit disc 110 in accordance with the transfer distance. On the right side of the above-mentioned rotary encoder 106, a rubber roller 116 is installed.
Similarly, an auxiliary roller 118 that is rotated with a part of its circumferential side protruding below the case 100 is provided. The auxiliary roller 118 is used when the mouse 36 is used for editing.
It cooperates with the rubber roller 116 to regulate the direction of movement so that it can move straight above.

The distance the mouse 36 is moved over the document 40 is converted into a rotation of the slit disk 110 by the rubber roller 116 . The slit disk 110 changes the light emitting element 1 according to its rotation.
In order to block the 12 lights at regular intervals, the light receiving element 114 outputs a voltage signal with a frequency corresponding to its rotation speed.

The voltage signal from this light receiving element 114 is sent to the voltage comparator 120.
The signal is shaped into a pulse, and is applied to the control section 98 of the main body 12 via the connector 122 and the elastic cord 38.

As shown in FIG. 7, the upper surface of the case 100 of the mouse 36 is provided with various operation keys 124 to 130 and LEDs 124a to 132b that indicate when these keys have been operated. Edit key 124 is used when editing manuscript 40 using mouse 36. Edit key 124
When is operated, the LED 124a lights up. Trimming/masking key 126 and movement key 128, which are operated after operating edit key 124, are keys for selecting which mode to use mouse 36. Trimming/masking key 126 and movement key 128
LEDs 126a to 128a are provided at the top of the screen to indicate that the corresponding keys have been operated. Therefore, for example, if you want to use the mouse 36 in masking mode, after operating the edit key 124, operating the trimming/masking key 126 twice will cause the LED 12
6a lights up.

Trimming/masking key 126 and movement key 12
8 are provided with an X key 130 and an X key 132 for setting the X and Y coordinates of editing, respectively. Below the edit key 124 are four LEDs 130a that indicate that the X and Y coordinates of two points have been set using the X key 130 and the X key 132;
130b, 132a and 132b are provided. L.E.
D130a-132b are lit when the mouse 36 is used in trimming or masking mode. In this embodiment, the area to be trimmed or masked is designated by a quadrilateral with two diagonal points. Then, when the coordinates of one point are input, the LED 13
When the coordinates of two points 0a and 132a are input, the LEDs 130b and 132b are lit, respectively.

To enter the move mode, first operate the edit key 124, then operate the move key 128 to confirm that the LED 128a is lit, move the mouse 36 to the desired position, and press the X key 130 and the 1 - key 132. All you have to do is operate. Then, LEDs 130a to 132b light up,
Coordinate data for movement in accordance with movement of the mouse 36 is set.

When the trimming or masking mode and the movement mode are used together, the movement mode is activated by the movement key 128 after specifying the area for the trimming or masking mode. At this time, LED130a to 132
b is already lit due to the setting of the trimming or masking mode, so even if the X key 130 and the X key 132 are operated after the movement key 128 is operated, the lighting does not change.

If you make a mistake in operating the key, for example if you operate the trimming/masking key 126 when you want to use it in move mode, operate the edit key 124 again and press the mouse 36.
Clear the function. When the edit key 124 is pressed twice, the mouse 36 returns to its initial state, ie, the state in which the original is not edited. If you make a mistake in operating the X key 130 or the X key 132, you can similarly operate the edit key 124 and start over from the beginning.

FIG. 8 is a block diagram showing an example of the control system of this embodiment. The control system includes a microcomputer 134. This microcomputer 134 not only controls editing but also controls the entire operation of the electronic copying machine. Although details are not shown, the microcomputer 134 includes a CPU, a ROM connected to the CPU for storing control programs, and a ROM that temporarily stores data and is necessary for control when controlled by the CPU. area for various flags, timer area and LED

AM is included.

A mouse 36 is connected to the input port of the microcomputer 134 via one elastic cord 38. The elastic cord 38 includes three signal lines, and through each signal line, the microcomputer 134 receives a pulse (pulse train) from the voltage comparator 120 and a magnetic sensor output when the magnetic tape 22 is detected. The output of 104 and the data of key matrix 138 contained in mouse 36 are input.

Furthermore, the microcomputer 134 contains data of the key matrix 140 of the main body 12 and the paper size sensor 6.

An amplifier 144 is connected to the microcomputer 134, and a sounding element 146 such as a buzzer is connected to the output terminal of the amplifier 144 to notify the operator that the mouse 36 is moving.

That is, when the mouse 36 is moved during editing, the rubber roller 116 rotates, and a sounding body drive signal is output from the microcomputer 134 in response to a pulse applied from the voltage comparator 120.

The amplifier 144 amplifies this signal and drives the sounding element 146, thereby audibly informing the operator that the mouse 36 is being moved.

In addition, the output port of the microcomputer 134 has
A partial erase lamp or LED array 48 is connected for erasing electrostatic latent images that are no longer needed due to editing. The operation of this LED array 48 has been described above.

Next, prior to explaining the operation, each of the trimming mode, masking mode, and movement mode will be briefly explained with reference to FIGS. 9A to 11B.

In trimming mode, two designated points Pl (XI, YI) and p, (Xs, Y

A plurality of LED elements 50, 50 . . . . are lit only outside this area 1,48.

In the masking mode, two designated points P, (X,,Yl) and P2(Xz
, Yz) is erased, and the remaining portion of the image is left as is, as shown in FIG. 10B. Therefore, in this mode, the plurality of LED elements 50 included in the LED array 48,
50. . . . are lit only within this area 150.

In the movement mode, as shown in FIG. 11A, the coordinates PI (XI, YI) of the leading or trailing edge of the moving image are
, and then specify the coordinate P2 (X2.YI) of the point to be moved while keeping the Y coordinate constant.

Then, when the toner image is transferred to the recording paper,
The coordinate position X, is moved to X2, and an image as shown in FIG. 11B is formed. That is, in this mode, LE
The D array 48 is not used, and the paper feeding timing is controlled by coordinate data, as will be described later.

Before starting the copying operation, as shown in FIG. Place the document 40 so that it is in close contact with the left corner; t-

by hand and move it onto the document table 14. and,
By means of the mouse 36, the coordinates PI (
Determine Xl, Yl) and P2 (Xz, Yz). The coordinate X1 of the coordinates PI (XI, Yl) can be set as follows. First, align the hole 102 of the mouse 36 on the magnetic tape 22. Then,
As shown in FIG. 13A, the magnetic tape 22 is detected by the magnetic sensor 104, and a reference point signal is input from the magnetic sensor 104 to the microcomputer .

When the output of the magnetic sensor 104 is input to the microcomputer 134, the microcomputer 134
Thereafter, pulses outputted from the voltage comparator 120 in accordance with the rotation of the rubber roller 116 are counted. Then, move the mouse 36 to X so that the hole 102 is placed on the point P.
Translate it in the axial direction by hand. When the hole 102 is positioned above the point P1, by operating the X key 130 (FIG. 7),
At that time, the count value, ie, data corresponding to Xl, is set in the RAM of the microcomputer 134. Y
When setting the coordinate position Y, move the mouse 36 to
The holes 102 are placed on the magnetic tape 22 in the same way as when Xl was set as shown by the dotted line in FIG.

Thereafter, the mouse 36 is manually translated in parallel in the Y-axis direction so that the hole 102 is located above the point P. Hole 102 is point P
, and when the Y key 132 (FIG. 7) is operated, Y, is stored in the RAM of the microcomputer 134.

When the setting of Yl) is completed, the point Pt CXz, YZ)
It will be easily understood that this point P2 can also be set by the same operation as the point P. Then, point P+ (Xl, Y+) and point P2 (X2.YZ
) is set, all of the L and EDs 130a to 132b are turned on, and an area 148 is set in the microcomputer 134.

In addition, in the example, the starting point (reference point) of the X axis and Y axis is
As shown in FIG. 13A, the determination is made in response to the output from the magnetic sensor 104 that detects the magnetic tape 22.
This may also be done in other ways.

For example, as shown in FIG. 13B, a reflective tape 148 having a high light reflectance is provided, light is irradiated onto the reflective tape 148 from a light emitting element 150, and the light reflected from the reflective tape 148 is detected by a light receiving element 152. Alternatively, the reference point or starting point signal may be input.

Furthermore, mechanical methods other than the magnetic and optical methods described above may be used, for example, by operating a movable piece of a microswitch (not shown) provided inside the mouse 36 on the positioning plate 20 to input the starting point. would also be possible.

Next, with reference to FIG. 8, the operation or operation of this embodiment will be explained based on the flowcharts shown in FIGS. 14 to 16.

After specifying the position of the original 40 for editing, turn the original 40 over as shown in FIG. Replace 40. Thereafter, the document cover 18 is closed and the document 40 is fixed onto the transparent glass plate 16. Then, the user operates the start key 28 to start the copying operation.

When the start key 28 is operated, in the first step Sll in FIG.
The main motor 96 for driving etc. is turned on.

When the rotation of the main motor 96 becomes stable, that is, when 1 sec has elapsed since the main motor 96 was turned on, the solenoid of the cleaning device 88 is turned on and the tip of the blade 90 is brought into contact with the photoreceptor drum 46 . When a predetermined period of time has elapsed since the solenoid was turned on, that is, when 100 m sec, for example, has elapsed so that no load is applied to the power supply at the same time, the process proceeds to the next step S13.

In step S13, the microcomputer 134
By looking at the signal from the sensor circuit 142 (FIG. 8), it is determined whether the document table 14 is at the home position, that is, whether the right end of the document table 14 is located on the left side of the main body 12. If the document table 14 is at the home position,
If the process does not proceed to the next step S17, then in step S15, a return clutch (not shown) for moving the document table 14 to the home position is turned on, and the document table 14 is returned to the home position. This return clutch is turned off by interrupt processing, which will be described later.

In step S17, the transfer corotron 72 is turned on. After turning on the transfer corotron 72, the process proceeds to the next step S19. In step S19, it is determined whether the copy is a manual feed copy, that is, whether the recording paper 58 is fed manually rather than from the paper feed cassette 32.

If it is a manual copy, the process advances to the next step S21, and the solenoid of the cleaning device 88 that was turned on in the previous step Sll is turned off. If it is not a manual copy, the process does not go through step 321 (proceeds to step S23).

In the next step S23, the paper feed clutch is first turned on, the paper feed roller 66 starts rotating, and the recording paper 58 is conveyed toward the register roller 70. At the same time, the solenoid of the cleaning device 88 is turned off. The solenoid is turned off twice in the case of manual copying in the previous step 319, that is, when the copy goes through step S21, but since only the off signal is supplied, there is no change in the solenoid. After 200 msec from turning off the solenoid, the next step S2
Proceed to step 5. This 200 msec time is JA when the paper feed clutch is turned on and the recording paper 58 is conveyed.
It's time to judge M.

In step S25, it is determined whether the document table 14 is at the home position, and if it is at the home position, the process advances to the next step 327.

In step S27, the microcomputer 134
It is determined whether the mouse 36 has been designated to move the image to the right in the movement mode. That is, after the edit key 124 (FIG. 7) of the mouse 36 is operated, the movement key 1 is
28. It is determined whether the X key 130 and Y key 132 are set to move the image to the right.

If the image is set to move to the right, the process advances to step S29, and if the image is not set to move to the right, the process advances to step S51.

In step S29, it is determined whether this 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 S31, after 300 msec has elapsed, a feed clutch (not shown) for scanning the document table 14 is turned on. In the next step S33, the document table 14
Determine whether or not the image position 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 it is not the image position, the time from the home position to the image position is counted by a counter in the next step S35.

Once the image position is reached, the process advances to the next step 337. In step S37, the feed clutch is turned off, and 200 m5ec later, the return clutch of the document table 14 is turned on.

In this way, when right movement is set and the first copy is being made, the time from the home position to the image position is unknown for the first copy, so the document table 14 must be moved before copying begins. , it is necessary to measure the 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, proceed to the next step S41, and step S4
1, step S in which the time to move the image to the right is first
It is determined whether the time is greater than the sum of the time counted in 35 and 1020102O. This 1020
m s e c is 200 m5ec set in step S51, which will be described later, and 300 m5ec after step S53.
sec, 100ms set in step S55
e c and 4 20 set in step 371
It is the sum of m sec. That is, in order to move the image to the right, it is necessary to advance the feeding of the recording paper before the formation of the latent image, but this advance time does not last until the original paper feeding start time, that is, the timing of resist clutch on in step S75. Determine if it is longer than the time.

If the image movement time is greater than the sum of the value counted in step S35 and 1020102O, the registration clutch is turned on in the next step S43, and the timing is adjusted in step 344 before proceeding to step 349. If it is determined "No" in step S41, the process proceeds to step S47, and the time difference is set in the registration clutch on timer (not shown).In this way, the moving time is the image position counter time + 1020 m5e.
If the time difference is shorter than c, the time difference is set in a timer in RAM, and the timer is counted in 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 341 has already been determined by the first copy. Therefore, in step S45, it is determined whether the moving time of the image is greater than the sum of the time counted in step S35 and 720 msec.

This 720m5ec is 102Q m in step 341
It is calculated by subtracting 300 m5ec, the time required for changing the direction of the document table 14 set after step S53, from s e C, and the feeding timing is earlier than the original paper feeding timing (
(preceding) is the time to turn on the registration roller clutch. In step S45, the travel time is determined in step S35.
If it is greater than the sum of the time counted in and 720 msec, the process proceeds to step S43, and if it is smaller, the process proceeds to step S47. Therefore, if the determination in step S45 is "No", that is, if the travel time is short, then the subsequent timing can be determined by the interrupt routine, as in the case of "NO" in step 341. did.

In step S49, the LED array 48 is turned on so that all the LED elements 50 are lit.

That is, the microcomputer 134 gives a signal for ``all lighting'' to the LED array 48. When moving the image to the right, the image on the left side of the document 40, for example, the image of the positioning plate 20, is placed on the photoreceptor drum 46. In order to prevent unnecessary electrostatic latent images from being formed thereon, the LED array 48 is fully turned on at this point.

After that, in step S51, the light source 42 for irradiating (exposing) the document 40 with light is turned on, and since the light source 42 starts up slowly, the process proceeds to the next step S53 after a time of 200 msec. As in the previous step S29, it is determined whether this is the first copy.

If it is the first copy, the light source 42 turned on in the previous step S51 is slow to start up, so an additional 300 m5 is required.
After the stabilization time of ec has elapsed, the process advances to step S55.

In step S55, the charging corotron 4 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 next 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 S61.

In step S61, the microcomputer 134
It is determined whether the trimming mode is set by looking at the signal from the mouse 36. When in the trimming mode, the trimming/masking key 126 of the mouse 36 is operated and the LED 126a is lit, so the microcomputer 134 only needs to check the state and make a determination. If it is determined in step S61 that it is not the trimming mode, in the next step S63, the LED array 48 that was turned on in the previous step S49 is turned off or extinguished. If it is determined that the mode is trimming mode, the process proceeds to step S65, and on the other hand, the LED array 48 is kept on, that is, fully lit.

In step S67, the microcomputer 134
The signal from the mouse 36 is checked to determine whether the masking mode is set.

In the masking mode, when the trimming/masking key 126 is operated with the mouse 36, the LED 126b
Since it is lit, the microcomputer 134 only has to judge whether it is in that state. If it is determined that the mode is masking mode, the process advances to the next step S'69.

In step S69, the position of the point P for trimming or masking set with the mouse 36 and the X coordinate of P2 is checked. Specifically, after the start of X coordinate detection is determined in an interrupt routine to be described later, the detection is performed in the interrupt routine. Then, in step S71, the time until the document table 14 finishes feeding is counted. After that, after a time of 420 m5ec corresponding to the normal paper feeding timing has elapsed, the next step S7 is performed.
Proceed to step 3.

In step S73, as in step 327, it is determined whether the image moves to the right. If the movement is to the right, the registration clutch has already been turned on and the registration rollers 70 have been driven in the previous step S43, so it is determined whether the registration rollers 70 are driven and the process proceeds to step 377.

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 leftward movement is counted in the next step S74, and then the registration clutch is turned on in step S75.

In step 377, when it is detected that the document table 14 has been fed to the return position, the next step S
Proceeding to step 79, the return clutch is turned on, and
The exposure light source 42 is turned off, and the LED array 4 that was turned on in the previous step 349 is turned off.

In the subsequent step 581 (FIG. 14B), the microcomputer 134 checks the number of copies 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 383, and then 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 advances to step S85, and the return clutch that was turned on in step S79 is turned off. After that, the photosensitive drum 46
After the time period during which the upper electrostatic latent image is transferred to the recording paper 58, for example 200 m5ec, the charging corotron 72 is turned off. Then, the process proceeds to step S87, and in step 387, 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. In step S89, the main motor 9G is turned off after the time 200 m5ec required to eject the recording paper 58. The copying machine then goes into standby mode.

Next, the interrupt routine of this embodiment will be explained with reference to FIG. This interrupt routine is 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 also determines the ON timing of the registration clutch in the movement mode, and
Controls the lighting position and timing of the D array 48.

In the first step 5IOI, the microcomputer 134 determines whether the document table 14 is at the home position, similar to step S13 in FIG. 14A. If it is not the home position, the process directly proceeds to step 5105, but if it is the home position, the return clutch is turned off in step 5103, and then the process proceeds to step 5105.

In step 5105, it is determined whether or not the paper feed sensor is on, that is, if the recording paper 58 reaches the register roller 70.
Determine whether the has been transported.

Then, when conveyance of the recording paper 58 is confirmed, the paper feed clutch is turned off in the next step 5107. Then proceed to step 5ill. If the preceding recording paper is being 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 5il.
Proceed to l.

In step 5ill, if rightward movement of the image is set using the mouse 36, it is determined in step S47 whether the time difference between the movement time and the start timing of the electrostatic latent image has been set in the timer of the RAM. This step 5
If "YES" is determined in "ill", the microcomputer 134 determines whether the on-timer has timed up in the following step 5113.

Then, after going through several interrupt routines, when the resist clutch on timer times out 7 times, step 5 is executed.
At 115, 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 5117, the microcomputer 134 determines whether the trimming mode or the masking mode has been set and 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 set.

When the start of X coordinate detection is determined, the next step 5119
, the microcomputer 134 determines that the left corner of the area to be trimmed or masked (designated by points P and P2) is a partial erase ramp, that is, L.
It is determined whether the position directly below the ED array 48 has been reached. When the area to be trimmed or masked reaches this LED array 48, the microcomputer 1
34 provides a signal to the LED array 48 to illuminate all LED elements 50 outside the region in trimming mode and to illuminate all LED elements 50 within the region in masking mode. Thereby, in step 5123, the LED elements 5 of the LED array 48 required for trimming or masking are
0 is partially selectively illuminated.

If it is determined "No" in step 5119, the microcomputer 134 determines in the following step 5121 whether the right corner of the area to be trimmed or masked has reached directly below the LED array 48. Once this is detected at 5121, 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 LEDs of the LED array 48 that were partially lit in step 5123
All D elements 50 are turned off. These two steps 51
27 or 5129, the microcomputer 134 completes the detection of the X coordinate in step 5131.

In the subsequent step 5133, the microcomputer 134 determines whether the counting of the positions to which the document table 14 should be returned, which was started in the previous step 371, has started. Then, in step 5135, the length of the document in the direction of movement of the document table (including the margin)
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 returned. If it is determined "YES" in this step 8135, the microcomputer 13
4 turns off the feed clutch in the next step 5137, and finishes counting the feed position in the next step 5139.

In subsequent step 5141, the microcomputer 134 determines whether the left image movement mode is set based on the signal from the mouse 36.

If left movement mode is set, the next step 5
In step 143, the LED array 48 is fully turned on in order to erase unnecessary electrostatic latent images due to the leftward movement, and in step 5145, the charging corotron 47 is turned on.
(FIG. 2) is turned off to prevent the photosensitive drum 46 from being charged thereafter. After step 5145 is executed, the process returns to the main routine shown in FIGS. 14A and 14-B, as in the case where "No" was determined in the previous steps 5133 and 5135, respectively.

As described above, according to the above embodiment, in the trimming mode or the masking mode, the lighting area of the LED array (partial erase lamp) 48 is adjusted in accordance with the area defined by the two points P1 and P2 set by the mouse 36. or control the range. Furthermore, when the movement mode is set, the microcomputer 134 controls the mouse 36
The deviation between the image position and the paper feeding timing is controlled according to the amount of movement based on the position data input from the image position.
