sec. As described above, there is a difference between the reading scanning speed and the image forming speed, and the frame memory 104 for one page of A3 size is used for the speed buffer. Further, since the TPS comes into contact with the original document and scans the original document to read the frame memory 104, image data is repeatedly read a plurality of times during the repeat copy, which is effective for protecting the original document during the repeat copy. Is. Further, in the present apparatus, since the images on the left and right pages of the spread document are independently printed, the images on the left and right pages can be divided and output by using the frame memory 104 in one scanning reading at the time of continuous shooting. The TPS does not require synchronous scanning with the image writing of the laser printer 501 or rerunning.

Further, due to the speed correspondence of the IPU 103, the frame memory 104 having a 4-bit dot structure is used for the IPU 1
By placing the image data after the image processing by the IPU 103 in the frame memory 104, the capacity of the frame memory 104 is halved for the read image data of 8 bits for each dot. The capacity of the frame memory 104 is 400 dpi and is A

FIG. 3 shows the overall structure of the TPS. This T
In the PS, an original placing table 206 made of contact glass and a scale 207 are arranged on the upper part of the apparatus main body, a sheet original is placed on the contact glass 206, and a pressure plate (not shown) is placed thereon. The document on the contact glass 206 is scanned by the scanning unit 200 to read an image. The upper half of the main body of the TPS device is a scanner unit 30, and the scanning unit 200 runs inside the scanner unit 30 in the horizontal direction in FIG.

FIG. 4 shows the scanning unit 20 in this apparatus.
The 0 page turning section is shown. Turning belt 2 in this device
No. 08 is made of PET, PC, PVC or the like, and has a double structure resin including a surface layer made of a high resistance film having a surface resistance of 10 ¹⁴ Ω or more and a back layer made of a low resistance film having a surface resistance of 10 ⁸ Ω or less. It is made of film. Also,
The turning belt drive roller 223 is composed of a metal roller whose surface is coated with a conductive rubber and is grounded, and realizes reliable driving and grounding of the turning belt 208. The turning belt 208 is stretched between the turning belt drive roller 223 and the turning roller 224, and is turned over.
It is rotationally driven by 23.

Further, the charging roller 225 is composed of a metal roller or a roller in which the surface of the metal roller is coated with a conductive rubber.
A high voltage of ± 2 to 4 kV is applied at a predetermined timing from the AC power supply 253 via 53a. The AC power supply 253 is controlled by the pulse from the pulse generator 253b.
While the scanning unit 200 runs and the turning belt 208 is driven, the changeover switch 2
53a is turned on, and the charging roller 225 is driven by the high-voltage power source 253 to a frequency of the pulse generator 253b ± 2 to 4k.
When an AC high voltage of V is applied, an alternating electric field is generated on the surface of the turning belt 208 by the charging roller 225, and the action of this alternating electric field attracts the top page 254 of the original document BO to the surface of the turning belt 208. Power is generated. The high voltage power supply 253 is arranged in the scanning unit 200.

When the scanning operation for reading the original is started, the scanning unit 200, which was at the left end home position of the scanner unit 30, starts traveling rightward in FIG. At this time, the turning belt 208 and the page feed roller 250 are moved to the position shown by the solid line in FIG. 4 by a solenoid (not shown). Then, the scanning unit 200
When the original document reading position on the lower side of the platen glass 206 of the original document BO reaches the left page of the original document BO, as shown in FIG. Read from the right page. Here, the main document reading start position of the scanning unit 200 changes depending on the size (size) of the main document BO.

In this way, the scanning unit 200 reads the surface of the original BO from the left page to the right page. During the image reading operation of the scanning unit 200 as shown in FIG. 5, the turning belt 208 and the page feed roller 250 are held at the positions shown by the solid line in FIG. Then, when the scanning unit 200 finishes reading up to the edge of the double-page spread of the original document, the original scanning direction of the scanning unit 200 is reversed as shown in FIG.

At this time, as shown in FIG. 6, the turning belt 2
08 and the page feed roller 250 are moved to a position indicated by a broken line in FIG. 4 by a solenoid (not shown). At about the same time, the changeover switch 253a is turned on, and the pulse generator 253b and the high-voltage power supply 253 apply an AC high voltage of a predetermined frequency to the charging roller 225 via the changeover switch 253a, so that the surface of the turning belt 208 is covered. A charge pattern is formed.

When turning the pages of the original document BO,
The turning belt 208 and the page feed roller 250 are located at the positions shown by the broken lines in FIG. 4, and the charging pattern portion formed on the surface of the turning belt 208 prior to the page turning operation is the top page 254 of the original document BO. Overlap. Then, when the tip of the top page 254 crosses over the center of the lower side of the turning belt 208, the turning belt 208 and the page feed roller 250 are shown by the solid line in FIG. 4 by the action of a solenoid (not shown) as shown in FIG. Be moved to a position. As a result, the top page 2 of the original document BO is attracted by the attraction force due to the uneven electric field of the charge pattern formed on the surface of the turning belt 208.
Only 54 is attracted onto the surface of the turning belt 208 and the end of this top page 254 is lifted with the turning belt 208.

The top page 254 of the original document BO is flipped up and the scanning unit 200 moves again toward the end home position as shown in FIG. 7, and the top page 254 of the original document BO is shown in FIG. As described above, the sheet is sandwiched between the turning roller 224 and the page feed roller 250 and is reliably conveyed. The uppermost page 254 passes between a pair of upper and lower page guides 227 and 228 arranged on the right side of the scanning unit 200, and its tip side is sent to the outside of the scanning unit 200 on the right side. At this time, the page sensor 214 mounted on the upper side of the scanning unit 200 detects the original page sent to the outer right side of the scanning unit 200, and it is detected that the original page is normally turned.

Next, as shown in FIG. 9, when the uppermost page 254 of the original document BO is turned up to the binding portion of the original document, the turning belt 208 and the page feed roller 250 are at their original positions (the positions indicated by broken lines in FIG. 4). ) Return to. In this state, the scanning unit 200 further moves toward the end home position,
As shown in FIG. 10, the original pages that have been turned up are pulled by the binding portion of the original document and returned between the pair of page guides 227 and 228 while being overlapped on the left page of the original document BO and inside the scanning unit 200. Emitted from.

The turned-up original page 254 is the original original B.
When all are overlapped on the left page of O, the scanning unit 20
One image reading / page turning operation for the 0-page spread original is completed. Here, when the image reading / page turning operation is repeatedly executed on the original document BO, or when only one of the image reading and page turning operations is repeatedly executed, the original page turned up as described above. When 254 is entirely overlapped on the left page of the original document BO, the moving direction of the scanning unit 200 is reversed and the scanning unit 200 is shortest with respect to the original surface of the original document.
The reciprocating operation of is repeated. The scanning unit 200
In some cases, only the image reading operation of the original document BO or only the page turning operation is performed.

When the document page 254 electrostatically attracted to the turning belt 208 is turned over, the end of the page 254 attracted to the turning belt 208 is swung by the solenoid so that the end of the page 254 is on the scanning unit 200 side. It is done by being lifted to. At this time, the original document BO
The page sensor 214 detects whether or not the page has been turned. When page detection by the page sensor 214 is not performed at a predetermined timing during page turning, the page turning operation is re-executed.

As shown in FIG. 11, the mirror 222 is driven by a mirror switching solenoid. When the mirror switching solenoid is turned on / off, the mirror 222 is moved back and forth to the optical path. The upper reading optical path is switched. As the light source for illuminating the original, two fluorescent lamps 201, 202, 2 provided in each of the upper and lower reading portions of the scanning unit 200 are used.
03 and 204 are used respectively.

When reading the original on the contact glass 206, the mirror 222 advances into the optical path, the original on the contact glass 206 is illuminated by the fluorescent lamps 203 and 204, and the reflected light is reflected by the mirrors 222, 220 and 221 and the lens 216. Through the CC on the image reading plate 101
An image is formed on D and photoelectrically converted. When reading the original document, the mirror 222 is retracted from the optical path and the original table 1 is read.
The upper original manuscript illuminates the original manuscript on the manuscript table 1 through the platen glass 205, and the reflected light is reflected by the mirrors 219 and 22.
Image reading plate 1 through 0, 221 and lens 216
An image is formed on the CCD on 01 and photoelectrically converted.

By the way, as shown in FIG. 3, the manuscript table unit 35 in the present apparatus is provided with one manuscript table 1 on each of the left and right sides of the center of the apparatus body, and the link mechanism 11 is provided.
It is supported by the vertical movement. Each platen 1
The springs 13 applied to the link mechanism 11 are respectively pressed upward. Further, as shown in FIG. 12, a document holding plate 14 is provided on the back side of the document table 1 via a hinge 12.
Is rotatably supported on the document table 1. A stopper claw 15 is provided at the front end of the document pressing plate 14, and the stopper claw 15 is provided on the front side of the document table 1 when the document pressing plate 14 is laid down on the document table 1 in FIG. It is adapted to be locked by the stopper 16.
As described above, in the document table unit 35 of this apparatus, since the stopper mechanism of the document pressing plate 14 is on the front side of the document table unit 35, the operation of the document pressing plate 14 can be easily performed.

On the other hand, a plurality of holes 1a are formed on the upper surface of the document table 1.
, And a part of the stator 17 is projected from these holes 1a. Further, rubber plates 18 for surely pressing and fixing the cover of the original document BO are attached to the upper surfaces of the stators 17. Each stator 17
Is a rotary shaft 20 fixed near the center of the document table 1.
(See FIG. 13), each of which is rotatably supported.
Further, each stator 17 is provided with a spring not shown in FIG.
Are urged in the directions indicated by the arrows.

As a result, as shown in FIG. 13, the front cover and the back cover of the original document BO are sandwiched between the document pressing plate 14 and the document table 1, and the stopper 15 of the document pressing plate 14 is engaged with the stopper 16. By stopping, the original document BO is securely fixed on the document table 1. In this case, in this device, each stator 1
By arranging 7 near the center of the apparatus of the document table 1,
With the stator 17 and the document pressing plate 14, the front cover and the back cover of the book document BO near the binding portion BOa can be pressed and clamped to more securely fix the book document BO on the document table 1.

Here, when the document holding plate 14 is fixed on the document table 1 in a state where the document BO is not placed, a gap of several mm is formed between the document holding plate 14 and the document table 1. It is set and configured so that a book document having a thick cover can also be fixed. Furthermore, in this device, as shown in FIG.
As shown in, the left platen 1 can only be moved up and down,
The main document BO placed on it is prevented from being displaced. On the other hand, the document table 1 on the right side is supported not only by vertical movement but also by the slide groove 21 so as to be movable in the horizontal direction in FIG. The right manuscript table 1 is urged to move to the left by a spring 10 so that a slide shaft 22 embedded in the link mechanism 11 abuts an end of a slide groove 21 on a side surface of the manuscript table 1. As a result, the movement of the document table 1 is stopped.

Next, the document table pressure fixing switching device and the document table retracting device of this apparatus will be described. Link mechanism 1
A document table 1 configured to be movable in the vertical direction by 1 is always biased by a spring 13 so as to move upward (see FIG. 3). As a result, in the state where the document table unit 35 is set in the apparatus and the document table pressing operation mode is entered, the original document BO which is opened and placed on the document table 1 due to the rising behavior of the document table 1 The surface is constantly pressed upward so as to be pressed against the lower portion of the scanning unit 200 in the scanner unit 30.

The pressing force on the original surface of the original document BO is normally received by the scanning unit 200. However, when the scanning unit 200 is moved to a position on the original table 1 which is out of the original document, the original table 1 is moved. Due to the rising habit, the document table 1 and the main document BO bite into the scanner unit 30 and hinder the smooth movement of the scanning unit 200. Therefore, with the platen 1 raised to an appropriate position, the platen 1
Must be fixed to prevent the document table 1 and the main document BO from excessively digging into the scanner unit 30 due to the rising behavior of the document table 1. Further, when the scanning optical path in the scanning unit 200 is switched by the mirror 222 to read the original on the contact glass 206 arranged on the upper part of the scanner unit 30, the lower part of the scanning unit 200 and the upper surface of the original table 1 do not contact each other. Manuscript stand unit 3
It is necessary to retract the document table 1 below the table 5.

The document table pressure fixing switching device and the document table retracting device are devices for satisfying these needs.
14 to 18 show a structural example of a mechanism in which both of these devices are combined by one mechanism. The control wire 40 of this mechanism has a hook 41 fixed to one end as shown in FIG. Another hook 42 is fixed to the other end of the control wire 40, and a spherical stopper ball 45 is fixed near the substantially central portion of the control wire 40.

The hook 41 is fixed to the outer end of the link mechanism 11 (the side that moves up and down as the document table 1 moves up and down). The control wire 40 extending from the hook 41 changes its direction via a pulley 46 and a pulley 47, and is wound around a control pulley 48. Where the control wire 40
As shown in FIGS. 15 and 16, the stop ball 4 is guided to the groove 50 of the control pulley 48 and fixed near the central portion thereof.
5 is fitted in a stop hole 49 of the control pulley 48.
This ensures that the movement of the control wire 40 is converted into a rotational movement of the control pulley 48.

The control wire 40 wound around the control pulley 48 and extended is always pulled by one end of a tension spring 43 hung on a hook 42 at one end thereof. The other end of the tension spring 43 is hooked on a hook 44 fixed to the base 6 of the document table unit 35. The control pulley 48 has a one-way clutch 51 as shown in FIG.
It is supported by the shaft 54 via. The shaft 54 is rotatably supported by the side plates 55 via the slide bearings 52 by the E-rings 53 preventing the shaft 54 from slipping off from the slide bearings 52 supported by the pair of side plates 55. ..

As a result, the control pulley 48 can freely rotate with respect to the shaft 54 in the direction of the arrow a in FIG. 16, but in the direction opposite to the arrow a, the one-way clutch 5 is rotated.
Due to the action of 1, the shaft 54 cannot rotate relative to the shaft 54, but rotates together with the shaft 54. Therefore, when the shaft 54 is fixed by the mechanism described later, the control pulley 48 becomes rotatable only in the direction of arrow a in FIG. 14, that is, in the rotation direction when the document table 1 is lowered.

Next, the lowering / fixing operation of the document table 1 by the document table pressure fixing switching device will be described. Figure 1
4 to 16, when the shaft 54 is in a fixed state, when the document table 1 is pushed down by some external force, for example, the weight of the document BO or the pressure of the page to be turned, the document table 1 is fixed to the document table 1 side. The end of the control wire 40 on the hook 41 side is loosened.

At the same time, the control pulley 48 causes the tension spring 4 to move.
3, the control wire 40 rotates in the direction of the arrow a while absorbing the slack on the hook 41 side of the control wire 40, and the control wire 40 maintains the initial tension and moves to the hook 44 side. At this time, the control pulley 48 cannot rotate in the direction opposite to the arrow a due to the action of the one-way clutch 51. Therefore, even if the raising force of the document table 1 exceeds the pressing force with respect to the document table 1, Control pulley 48 by ascending force
Is not rotated in the direction opposite to the arrow a, and the control pulley 48 is stopped while maintaining the position rotated in the arrow a direction. Further, the movement of the control wire 40 is also stopped in accordance with the stop of the control pulley 48, whereby the document table 1 is lowered to a position where it is pushed down by an external force and then stopped.

Here, the fixing of the shaft 54 is performed by a document table lifting mechanism described below. That is, the gear 56 is fixed to the shaft 54 so as to rotate integrally with the shaft 54 as shown in FIG. The gear 56 meshes with another gear 57 rotatably supported by a stud 59 fixed to the side plate 55 as shown in FIG. 18, and the rotation is transmitted to the gear 57. Has been done.

Further, the gear 57 is formed integrally with the worm wheel 58, and the worm wheel 58 is constituted so that the worm gear 60 fixed to the output shaft of the document table raising / lowering motor 61 meshes with the worm wheel 58. With this configuration, when the platen raising / lowering motor 61 is stopped, the worm wheel 60 cannot rotate due to the meshing between the worm gear 60 and the worm wheel 58, and the gear 56 meshing with the gear 57 integrated with the worm wheel 58 is not supported. The shaft 54 connected through the above is in a fixed state.

Next, the operation of retracting the document table 1 below the document table unit 35 will be described. 17 and 18, when the platen raising / lowering motor 61 is driven so that the gear 56 rotates in the direction of arrow b, the one-way clutch 51 causes the control pulley 48 and the shaft 54 to rotate integrally, and the control pulley 48 moves. The control wire 40 rotates in the direction of arrow a and moves to the hook 44 side.

Due to the movement of the control wire 40, the left and right manuscript tables 1 are lowered in FIGS.
At the positions detected by the left and right document table lower limit sensors 304 shown in FIG. The document table unit 35 is retracted to a lower position, that is, a position shown in FIG. This retracting operation is executed when the power of the apparatus main body is turned on or when the apparatus is in a standby state where scanning is not performed, when a document is read on the contact glass 206 disposed above the scanner unit 30 and when the document table unit 35 is pulled out.

Next, the operation of pressing the document table 1 above the document table unit 35 will be described. Contrary to the above-described retracting operation, in FIG. 17 and FIG. 18, when the platen raising / lowering motor 61 is driven so that the gear 56 rotates in the direction of arrow c, the shaft 54 moves in the direction opposite to the direction of arrow a in FIG. The control pulley 48 becomes freely rotatable with respect to the shaft 54 by the action of the one-way clutch 51. Here, in this apparatus, the force of the torsion spring 13 that pushes the document table 1 upward is set to be stronger than the force that pulls the control wire 40 downward.

Accordingly, when the control pulley 48 can freely rotate in the direction opposite to the direction of the arrow a, the control wire 40 is moved to the hook 41 side by the force of the torsion spring 13 that pushes the document table 1 upward. Moving. Due to the movement of the control wire 40, the left and right manuscript tables 1 are raised in FIG. .

As described above, when the original table raising / lowering motor 61 is continuously driven in a state where the left and right original tables 1 are raised and the original surface on each original table 1 is in pressure contact with the scanning unit 200, the one-way clutch 51 acts. The shaft 54 is allowed to freely rotate with respect to the control pulley 48, and the pressure contact state of the document surface to the scanning unit 200 is maintained. This pressing operation is executed only when the scanning unit 200 is on the document table 1, as described later.

As shown in FIGS. 3 and 20, one set of the platen pressurization / fixing switching device 50A and one set of the platen retraction device 50B are provided for each of the pair of left and right platens 1, and a scanning unit is provided. They are independently controlled according to the moving position of 200. That is, the pair of left and right platen raising / lowering motors 61, which are the driving sources of the platen pressure fixing / switching device 50A and the platen retracting device 50B, are independently controlled.

FIG. 20 shows the downward retracting operation of the document table 1 in the retracting operation mode described above, and FIG. 21 shows its timing chart. In this retracting operation mode, as shown in FIG. 21, the left and right platen raising / lowering motors 61 are rotated in reverse until the left and right platen lower limit sensors 304 detect each platen 1 before starting the movement of the scanning unit 200. As shown at 19, the left and right platens 1 are lowered. After that, the scanner motor 106 is driven to scan the scanning unit 200 in a predetermined direction, and the scanning of the scanning unit 200 is repeated many times if necessary. Then, at the end of this retracting operation mode, the scanning unit 200 returns to the central home position, the left and right platen raising / lowering motors 61 rotate forward a predetermined number of times, and the left and right platens 1 return to their original positions.

On the other hand, when reading a document on the contact glass 206, the scale 207 serves as a placement reference for the document end face. This reference is different from the reading start position of the original document so that the configuration has a minimum size. As a result, the reading start point of the document is always constant, and control is simple. When the sheet mode for reading the original on the contact glass 206 is entered, the scanning unit 200 moves to the left from the central home position after the original table lower standby operation, and the edge home detected by the edge HP sensor is detected. Position (scanning unit 20 shown in FIG. 22)
It comes to 0 position) and stops, and waits until the reading condition is input by the operation unit 99 and the start switch is turned on. Here, when the start switch is turned on, the scanner motor 106 is driven and the scanning unit 200 is moved to the position shown in FIG.
The document on the contact glass 206 is scanned by the scanning unit 200.

Next, the pressing / fixing operation mode of the document table 1 will be described. When the TPS operation is completed in the original document image reading mode, the scanning unit 200 returns to the center home position shown in FIG.
The scanning unit 200 is also located at the center home position when the is set. This is because the original document BO is set with the center of the TPS as a reference, so that the document table unit 35
This is to ensure that even if the original document of any size is set, the original document table 1 is raised and set after sliding and closing. At the start of this operation, the central HP sensor again confirms that the scanning unit 200 is in the central home position. Then, the scanning unit 200 moves to the left from the center home position, reaches the end home position (see FIG. 23) detected by the end HP sensor, and stops.

22 to 26 are transition diagrams of the scanning unit 200 when the original table 1 is in the pressure / fixing mode.
FIG. 27 shows the timing chart. The end home position (see FIG. 22) of the scanning unit 200 is an image reading page turning operation start point and an operation end point. At this end home position, the scanning unit 200 does not rest on the document table 1. In this state, the document table raising / lowering motors 61 on both sides are stopped, and the left and right document table 1 are both fixed.

In the pressurizing / fixing mode of the original table 1, first, the scanner motor 106, which is the drive motor of the scanning unit 200, rotates in the forward direction to move the scanning unit 200 to the right in FIG. When the document pressing roller 281a on the right side of the scanning unit 200 is applied to the left end of the original document BO (point A; see FIG. 23), the left platen raising / lowering motor 61 is rotated in the normal direction, and the left platen 1 is added. It becomes a pressure state.
As a result, the original document BO is pressed against the scanning unit 200, and optimum image reading is performed.

Shortly before the scanning unit 200 reaches the main document center point (see FIG. 24), the right document pressing roller 281a is caught on the left end of the right document table 1 (point B; see FIG. 27). At that time, the right platen raising / lowering motor 61 is rotated in the normal direction, and the right platen 1 is brought into a pressurized state. Next, the scanning unit 200 passes the center point of the book document and starts reading the image on the right page of the book document BO. After that, the left document pressing roller 281b is applied to the right end of the left document table 1 (point C; see FIG. 27). At this time,
The left platen lifting motor 61 is stopped, and the left platen 1
Becomes fixed. As a result, the original document BO is fixed and pressed by the document pressing sheet 282b without biting into the scanner unit 30 and waits for the next passage of the scanning unit 200 while keeping the same height.

FIG. 25 shows an operating state of the scanning unit 200 during reading of the right page of this document or turning up of the right page. In the scanning unit 200 that has finished reading the right page of this document, the left document pressing roller 281b is in contact with the right end of the right document table 1 (point D; see FIG. 26).
Then, the scanner motor 106 rotates in the reverse direction to move the scanning unit 200 leftward. As a result, the scanning unit 200 advances while flipping up the right page of the original document BO, and the left original pressing roller 281b is brought to the right end of the left original table 1 shortly before reaching the central point of the original document (see FIG. 24). It takes (C point). At that time, the left platen raising / lowering motor 61 rotates in the normal direction, and the left platen 1 is brought into a pressurized state.

Next, the scanning unit 200 passes the center point of the main document and starts the operation of superposing the turned up right page on the left page of the main document. After that, the right document pressing roller 281a contacts the left end of the right document table 1 (point B). At this time, the right platen lifting motor 6
1 is stopped, and the document table 1 on the right side is fixed. As a result, the original document BO is fixed and the scanner unit 30 is fixed.
The sheet is pressed by the document pressing sheet 282a without biting into the sheet, and waits for the scanning unit 200 to pass next while keeping the same height.

After that, the scanning unit 200 proceeds while superposing the turned-up page on the left side page of the original document,
After the superposition of this page is completed, the right document pressing roller 281a is applied to the left end of the left document table 1 (point A; see FIG. 23). At this time, the left platen raising / lowering motor 61 is stopped and the left platen 1 is fixed. As a result, the original document BO is fixed, and the scanner unit 3 is fixed.
It waits until the original pressing sheet 282b is pressed without going into 0 and the scanning unit 200 is next passed while keeping the same height. Then, the scanning unit 200 reaches the end home position (see FIG. 22) and stops.

Next, the document table front drawing mechanism will be described. As shown in FIGS. 3 and 20, slide rails 300 are connected to the left and right side surfaces of the document table unit 35 so as to be slidable in the front-rear direction of the apparatus body with respect to the rail brackets 301 in the scanner unit 30.

The microcomputer in the IPU 103 uses the effective image area signal PFGA on the printer 501 side in the sub-scanning direction.
The data read signal memory R of the frame memory 104 is operated by TE to output image data in synchronization with the printer 501. Further, when the page is turned, the page sensor 214 repeatedly detects the page edge of the two-page spread original. By repeating the above steps, the pages of the manuscript are automatically turned, and double-page spreads of the manuscript are copied.

FIG. 35 shows the case of the one-to-one copy mode in which an image is output for each independent page of this document. In this case, in the reading mode, the operation is performed at the same timing as in the case of FIG. 34, and at the time of page turning, the data read signal memory R of the frame memory 104 is set by the two PFGATEs in accordance with the transfer paper continuously conveyed by the printer 501. The image data for each page of this document is output by operation. When the address counter of the frame memory 104 is masked by PFGATE and stopped, the data of the second image on the right page connected to the image on the left page of the original document becomes the second PFG.
The ATE signal causes the printer 501 to read the data with a transfer sheet interval.

In this apparatus, the page sensor 214 detects the page edge of the document during the page-turning scanning of the document, and the suction and separation operation positions with respect to the page edge of the document that change due to repeated page-turning are determined. To be done. That is, the page end portion on the scanning end side is detected from the data of the page storage position, the page suction rising position at the time of page turning scanning is determined, and the same amount of the page is always sucked,
Controlled to separate.

Next, the mode control flow will be described. 36 to 41 show control flows in each mode. These controls are performed by the main controller (main control unit) that controls the image forming mode, and the IPU controller (controller of the IPU 103) controls the reading of the document image, the data processing, and the page turning according to the command. The sequence controller (sequence control unit) also controls the timing of the load on the image forming unit. Figure 3
6 is a page limited mode selection flow, FIG. 37 is a start left / right page determination flow, FIG. 38 is a copy page number setting flow, FIG. 39 is a final page left / right determination flow, FIG. 40 is a copy format selection flow,
FIG. 41 shows a reading selection flow.

First, the setting of the copy page number will be described with reference to the copy page number setting flow shown in FIG. As shown in FIG. 32, the operation unit 99 of this apparatus is provided with a copy page setting key 628 and a copy start page setting key 631 for setting the number of copy pages. There are the following two methods for setting the number of pages to be copied, which is selected by pressing each key. First start ~
In the end page input method, two numerical values of the copy start page and the copy end page of the original are input, the system control unit 802 calculates the number of pages from the copy start page to the copy end page, and the difference page is copied. To perform. The second page number input method is
This is a method for directly inputting the number of pages to be copied, and the system control unit 8
02 repeats the copying operation from the designated left page or right page for the designated number of pages. The latter is mainly used when this manuscript has no page number or when the pages to be copied are skipped.

The page number input operation method is displayed on the guidance display section 643 of the operation section 99 as shown in FIG. The input of the number of pages is indispensable for the repeated operation of image reading automatic page turning of the main document, and the system control unit 8 is used in the main document reading mode (main document mode).
02, first, the guidance display unit 643 displays the text guidance (or the display by blinking the display element) so that the page number input is set with the highest priority.

That is, the system control unit 802 displays a page number input request on the guidance display unit 643 when the image forming mode is set (when the mode is set in the main document reading mode or during warm-up standby), and the copy page setting is performed. The start-end page input method is specified by determining which of the start-end page input method and the page number input method is specified by the input signal from the key 628 (when the start-end page key is turned on). Check the input signals from the 10 key 642 and the enter key 640, which are used to set the number of copies, the copy start page input by the 10 key 642 is turned on by the enter key 640 or the copy page setting key 628. Enter the copy end page entered with the 10 key 642 with the enter key 64.
0 or the copy page setting key 628 is turned on to confirm.

Next, the system controller 802 checks the input signal from the page addition key 634 and checks the page addition key 63.
4 is turned on, the copy start page and copy end page input from the 10 key 642 as described above are entered.
The process of confirming by turning on 0 or the copy page setting key 628 is repeated. The input request display of the copy start page and copy end page of this manuscript is displayed on the guidance display section 643.
Alternatively, the display may be displayed by blinking the display element.

If the page number input method is designated (the start / end page key is not turned on), the system control unit 802 checks the input signal from the page number key 628 to check the page number key. If 628 is turned on, 1
0 key 642, enter key 640, copy page setting key 6
The input signal from 28 is checked, and the number of copy pages input by the 10 key 642 is confirmed by turning on the enter key 640 or the copy page setting key 628.

Next, the page limitation mode will be described. The page-only mode is effective in the original document reading mode.
6 shows a page-only mode selection flow. The page limited mode is (1) no page limited mode, (2) right page limited mode,
(3) There is a left page limited mode, and priority is given to the page limited mode so that the first setting is (2) right page limited mode and the second setting is (3) left page limited mode. The main controller sets the page limit key counter to 1 when the power is turned on, increments the page limit key counter each time the page limit setting key 621 is pressed, and when the page limit key counter becomes greater than 4, the page limit key counter is increased. Set 1 to the counter. Then, the main controller sets the mode without page limitation when the page limited key counter is 1 to turn off the light emitting diodes 622 and 623, and sets the right page limited mode when the page limited key counter is 2. Then, only the light emitting diode 622 is turned on, and when the page limited key counter is 3, the left page limited mode is set and the light emitting diode 62 is set.
Turn on only 3.

In the right-page limited mode, the main controller forms the read image of only the right page of the two-page spread original on the transfer paper, turns over the pages of the main document, and further displays the image of only the right page of both the two-page spread. Form on transfer paper. This image formation is performed by reading out only the image information of one page in the independent page mode from the frame memory 104 as shown in FIG. As for the image alignment, as described above, the page image position is calculated from the detection of the page edge of the original document, and the page image position is arranged on the transfer sheet. On the contrary, in the left page limited mode, the main controller forms the read image of only the left page of the two-page spread original on the transfer paper,
The pages are turned to further form an image of only the left page of the two-page spreads of the original on the transfer paper.

Some books are bound with one-sided printed matter, and many are bound with one-sided originals such as stapler stoppers and files which are generally used in offices. In bindings of those single-sided printed matter, the number of pages is generally numbered only on the image side, and even when the number of pages is not added, the number of originals is counted to count the number of pages. It is a thing. In this apparatus, when an image is formed only on the page (left page or right page) set in the page-only mode, the copy page of this document is set as the copy start page / copy end page, or the copy page. By setting the number of pages, the number of pages to be copied, that is, the number of originals is set.

In the mode for forming images of both double-page spreads of the main document, the main controller receives an input of the number of pages to be copied from the operation unit 99, counts the number of pages for each page of the main document, and sets in the page-only mode. In the mode in which an image is formed only on the page (left page or right page) on the side where the operation is performed, the operation unit 9
Accepting 1/2 of the input number of pages from 9
Count the number of pages for each page. Therefore, in both modes, the number of pages can be set easily, and reading of the number of pages, turning of pages, and image formation are surely performed.

Normally, the copy start page (left page or right page) of the original document is selected to start copying, but after that, when the page limitation mode in which only one page is copied is set,
The main controller cancels the selection result of the copy start page. When the copy start page is input differently from the designated page in the page-only mode later, the main controller cancels the selection result of the copy start page as shown in the start left / right page setting flow of FIG. Prioritize limited mode. When the limited mode is designated, it is not necessary to select the copy start page, and the guidance display prompting the selection input is not displayed.

Next, the selection of the copy start page will be described. The copy start page of this manuscript is (1) of the spread pages of this manuscript.
There are left page and (2) right page. Further, in the main controller, as shown in the start left / right page setting flow of FIG. 37, the left page is designated as the copy start page of the original by the copy start page set key 631 in accordance with the input signal from the copy start page set key 631 ( When the start left page key is turned on), the copy start page of this document is set to the left page of both pages, and the copy start page setting key 631 is used to set the copy start page of the document to the right as the copy start page. When the page is designated (the start right page key is turned on), the copy start page of this document is opened and set to the right page of both pages.

When the right page is designated in the copy start page mode, the main controller forms a read image on the transfer paper from the right page of the two-page spread original, and turns the page to form an image for each page. As shown in FIG. 42, this image formation is performed by the frame memory 10 in which the image information is divided into one page in the independent page mode.
Read from 4 and perform. As for the image alignment, the page image position is calculated from the page edge detection as described above, and the image is placed on the transfer paper. On the contrary, when the left page is designated in the copy start page mode, the read image is formed on the transfer paper from the left page of the two-page spread original document, and the page is turned to further form an image for each page.

Further, in the double-page spread mode shown in FIG. 42, in which both double-page spreads of the original are copied onto one sheet of transfer paper, the copy start page is input. This is determined by the copy start page and the previously specified number of copy pages as shown in the final page right / left discrimination flow of FIG.
It is used to determine whether the final page to be copied is a double-page spread right page or left page, and to determine a method for forming an image of the final page. Further, as shown in the final page right / left discrimination flow of FIG. 39, the main controller calculates the number of times of image reading and page-turning scanning of the main document based on the copy start page and the set number of copy pages. in this case,
When the copy start page is the left page and the set copy page number is an even number, the main controller determines that the last copy page is the right page, and divides the set copy page number by 2 and divides the integer part thereof by the scanning unit 200. However, in the case of the other three types, the value obtained by adding 1 to the value of the integer part is used as the scanning unit 20.
The number of scans is 0. Since this apparatus performs page-turning scanning after the final image reading scanning of this document, it ends,
The number of times of image reading and page turning scanning becomes equal.
The main controller determines that the last copy page is the right page when the copy start page is the right page and the set number of copy pages is odd, and the other two cases (the copy start page is the right page and the set copy page number is set). Is an even number, or the copy start page is a left page and the set number of copy pages is an odd number), the final copy page is determined to be a left page. As described above, the number of reading scans differs depending on the page layout of the original document and is also used for the control thereof. When the copy start page is selected, image formation is started from the copy start page in the independent page mode, and unnecessary pages are not copied.

Next, the copy format mode will be described. The copy format mode is effective in the original document reading mode and includes (1) independent page mode and (2) spread page mode. In this apparatus, priority is given to the copy format mode, and the first setting is the (1) independent page mode in which one page of the original document is formed on one transfer sheet, which is frequently used. Further, the initial setting of the copy format mode when the power is turned on or when the main document reading mode is selected is (1) independent page mode.

As shown in the copy format selection flow of FIG. 40, the main controller sets 1 to the copy format counter when the power is turned on, increments the copy format counter each time the copy format selection key 618 is pressed, and copies the copy format counter. When is greater than 3, the copy format counter is set to 1. Then, when the copy format counter is 1, the main controller sets the independent page mode to light only the light emitting diode 619, and when the copy format counter is 2, sets the spread page mode to the light emitting diode 620 only. Light up.

When the independent page mode is designated, the main controller reads the read page image of the two-page spread original document from the frame memory 104 for each page as shown in FIG.
Form on the page transfer paper. As for the image alignment, the page image position is calculated from the page edge detection as described above, and the image is placed on the transfer paper. On the other hand, when the spread page mode is designated, the main controller continuously reads the read image information of both pages of the spread book document from the frame memory 104 to form one page of transfer paper.

Generally, books and books are bound with double-sided printed matter, and there are also bound with double-sided originals such as stapler stoppers for office documents and files. In this device, which reads the original document and forms an image of the read page on the transfer paper, and turns the pages of the original document, in this device, an independent page mode in which an image for each page of the original document is formed on one sheet of paper, and a two-page spread of the original document By providing the double-page spread mode in which the images of both pages are formed on one page of paper, it is possible to obtain a copy having a different image forming form. In particular, the independent page mode has the same page structure as the original document. In the double-page spread mode, the number of copies is halved, and images such as gravure are spread over the double-page spread as continuous images.

Further, the present apparatus reads both page images of a two-page spread original document by one scanning, writes the read image data in the frame memory 104, divides the read image data into image ranges for each page, and divides the read image data into the frame memory. The image data is read out from the page 104 to form an image on one page of the sheet, and the read image data is continuously read from both sides of the page to be read from the frame memory 104 to form the images of both pages of the two pages of the original document on one page of the sheet. The reading is controlled to be the same in one unidirectional scan.

Next, reading selection will be described. This apparatus is provided with an image reading automatic page turning function and a sheet document reading function of this document. In this apparatus, the document reading modes are prioritized and the first setting is the document reading mode, and the default setting when the power is turned on or when the mode is cleared is the document reading mode. Further, this initial setting mode can be set programmable in the image forming unit and can be stored in a non-volatile memory accessible by the CPU of the main control board 107, and either document reading mode can be selected according to the application. It is like this. Further, by performing a preliminary operation for starting the original reading when the original reading mode selection is switched, the main unit waits in a state where the original can be set by homing the scanning unit 200 and moving the original table 1 when the original reading mode is selected. Further, the time for starting the original reading operation (time for homing of the scanning unit 200, switching of mirrors, fluorescent lamps and preheating, movement of the original table 1) is shortened.

As shown in the reading selection flow of FIG. 41, the main controller causes the reading selection counter to set the initial setting value of 1 or 2 in the nonvolatile memory when the power is turned on.
After the warm-up standby, the input signal from the main document key (read selection key) 601 and the detection means for detecting the presence or absence of the main document on the platen 1 is checked, and the read selection key 601 is pressed. At this time, the presence or absence of the original document on the platen glass 1 is judged, and if there is this original document, the reading selection key 601 is prohibited to switch the reading mode, and the document display warning display “Original document is left” is operated. This is done on the display panel of the section 99 to prevent the main document from interfering with the scanning of the operation unit 200 and the main document from being damaged when the sheet document is read. Also, since this document cannot be seen when it is set on the document table 1,
Notify the operator that you have forgotten to take this manuscript.

The main controller increments the reading selection counter each time the reading selection key 601 is pressed, and sets 1 to the reading selection counter when the reading selection counter becomes larger than three. When the reading selection counter is 1, the main controller sets the main document reading mode to turn off the contact glass reading (sheet original reading) light emitting diode, homing the scanning unit 200 (carriage), and the central mirror. 222 optical path retreat, fluorescent lamps 201,
02 is turned on to accept the original document set. Also,
When the reading selection counter is 2, the main controller sets the sheet document reading mode, homing the carriage, advancing the optical path of the central mirror 222, and the fluorescent lamp 2.
03 and 204 are turned on to accept the set of the original document.

Next, the image memory range will be described.
The present apparatus includes the frame memory 104 as an image memory for storing image data as described above, and the image memory 104 is used for the following purposes. Image memory 104
First, as a speed buffer for reading an original and forming an image, stability of contact reading by the scanning unit 200 of the original and protection of the original are performed. The image memory 104 is
Secondly, it is used for protection of originals and improvement of copy productivity by repeating copying by reading the original once. Image memory 10
Thirdly, 4 is used as a copy page layout for determining the initial page position and cutting out an independent page.

As shown in FIG. 42, the range for storing the image data of the original document in the image memory 104 is centered around the binding portion of the original document, and when the copy magnification is equal to or smaller than 1 ×, the image of the maximum spread A3 size of the original document is displayed. It is an area for storing data.
The image memory 104 is VP just before the area.
The storage of the image data from U102 is started by the IPU 103, and the surplus portion of the image memory 104 is arranged in the right direction. The image memory 104 is 16 MByte (128M
bit: to be precise, it has a storage capacity of 134, 217, 728 bits, and 4 bits after image processing from the VPU 102.
Image data of t / dot is stored in multivalue. Therefore, the image data storage range of the image memory 104 is slightly larger than the A3 size.

Next, the copy mode and function will be described. The copy mode, input keys and their functions of this apparatus will be described below with reference to FIGS. 1. Main document operation unit basic mode (1) Read selection ○ Sheet document (default) (Function) The document on the upper contact glass 206 is read to read the sheet document. Specify when copying a sheet document or the cover (hard cover) of this document. The sheet original mode is right alignment (reading scale 207, rear left corner), and cannot be used for anything other than scaling and double-sided printing with the same processing function as this original.

(Operation) Automatically returns upon completion of default or copying of the original document. The lower side of the original document (function) is scanned, and the image of the original document is read and automatic page turning is performed. Manual feed and interrupts are not allowed in this document reading mode. (Operation) When the original document reading mode is selected by pressing the original document key 601, the operation input of the original document is started. When the original document key 601 is pressed in the original document reading mode or the original document table is set after the original document is taken out, the sheet original document reading mode is returned to.

(2) Copy page setting start to end page (this original reading mode / default) (Function) The number of pages from the copy start page to the copy end page is calculated, and the difference page is copied. (Operation) Follow the guidance display to set the number of pages to copy.
1. Input the numerical value of the copy start page with the ten keys 642, 2.
2. Confirm the copy start page with the enter key 640, and 3. Enter the value of the copy end page with the numeric keypad 642. The enter key 640 is used to confirm the copy end page.

Number of Pages (Function) Copying is repeated from the designated left and right pages of the original document by the designated number of pages. In this case, it is not necessary to input the copy start page to the copy end page. This is used when there is no page number in this manuscript or when pages are skipped. (Operation) Follow the guidance display to set the number of pages to copy.
1. Enter the value of the number of pages to be copied with the ten keys 642. The enter key 640 is used to confirm the number of pages to be copied.

* Normally, in the double-page spread mode, one page of the original is counted as one page, and in the page limited mode of only the right page or the left page, it is regarded as a one-sided original and the copied page is counted as one page. (3) Add page setting Add page (Function) Specify up to three pages of this document, skip pages, and copy only the specified page group continuously. The number of skipped pages is not limited, but in the case of a large number of pages, the efficiency may be poor. For manuscripts in which the number of pages is changed and the pages are continuous,
For the copy page setting, only the settings from the copy start page to the copy end page are valid, and the left and right pages of the subsequent job are judged from the start left and right page of the first job. Mode settings other than the copy start page to copy end page settings are the same for all jobs.

(Operation) After inputting the copy start page to the copy end page, the page addition key 634 is pressed, and the copy start page to the copy end page of the next job is input according to the guidance display. By pressing the page addition key 634, the number of pages of each job can be confirmed and corrected.
Cancel. (4) Copy format mode Independent page (main document reading mode, default) (Function) Copy the spread pages of the main document separately for each page.

(Operation) By pressing the copy format key 618, one of the two-page spread left and right pages is selected. Spread Pages (Function) Copies both spread pages of this document on one side of the transfer paper. In the spread page mode, the copy start page is fixed to the left page. Both sides of the double-page spread, which forms the first double-page spread on the transfer paper surface and the second double-page spread on the back surface of the transfer paper,
Select with double-page spread originals in double-page spread mode.

(Operation) One of the independent pages is selected by pressing the copy format key 618. (5) Input of copy start page Left page (function) Copying is started from the left page of the document (placement) as an independent page.

(Operation) In the independent page mode, the left page is selected by pressing the copy start page key 631. Right page (Function) Starts copying from the right page of the original as an independent page. (Operation) In the independent page mode, pressing the copy start page key 631 selects the right page.

* Specify even when each duplex mode is selected. In the duplex mode, the first and last pages are automatically ejected as blank pages by setting the copy start page and the number of pages. Even if the number of input pages is odd in the double-page mode, the last page is a copy of both pages, and the first and last half-page designations (half-side erasing) cannot be performed. 2. Behind mode (this document related mode only) (1) Erase mode Center erase (this document reading mode, default:
Yes) (Function) Detects the position of the original document and erases the image of the specified width of the binding area with the center distribution based on the center of the two-page spread original.
In the independent page mode, the right edge of the spread left page and the left edge of the right page are designated by center erasing.

(Operation) By depressing the center erase key 635, the erase of the binding portion is released. Erase Frame (Main Document Scanning Mode, Default: Yes) (Function) Detects the size and position of the original and erases the image of the specified width inside the outer frame (top, bottom, left and right) based on this original. Even if you cancel the frame deletion,
The image is usually erased automatically and a large black frame is not formed around the transfer paper.

(Operation) By pressing the frame deletion key 636,
Releases the erasure of the spread outer frame of this document. To cancel the upper, lower, left and right erase settings independently, set the erase width setting value to "0".

* Because of the position of the document, the upper side: the erase function cannot be performed in the sheet reading mode. (2) Movement mode ○ Center (main document reading mode / default) (Function) Copy to the center of the transfer paper in the sub-scanning direction based on the transfer paper. The image shift in the sub-scanning direction detects the page length of the original document and arranges it on the transfer paper. Shrinkage due to the binding part of this manuscript,
The surplus due to the irregular size original is distributed to both ends of the transfer paper to prevent image loss and avoid the effect of registration error.

(Operation) By pressing the move key 609, the left-right alignment is canceled. Right alignment (function) Copy to the set movement amount position on the right side of the transfer paper in the sub-scanning direction with reference to the transfer paper. This is effective when providing a binding margin, and the binding margin is created on the left side of the transfer paper by the shrinkage of the binding section. In the sheet document reading mode, right alignment is fixed and the leading edge is the same as in the conventional apparatus. The binding margin creation in the sheet document reading mode is supported in the SP (service program) mode as in the conventional apparatus.

(Operation) By pressing the move key 609, right alignment is selected. Left alignment (function) Copy to the set movement position on the left side of the transfer paper in the sub-scanning direction with reference to the transfer paper. When providing a binding margin that is equal to or greater than the shrinkage of the binding section, and when providing a binding margin with a fixed width, the left alignment is specified together with the movement amount change. In the case of a right binding original (vertical writing original), a binding margin is created on the right side of the transfer paper.

(Operation) The left key is selected by pressing the move key 609. * Even when the double-page spread is output, it is also effective, and it is placed on the transfer paper according to the length of both pages of the double-page spread original. When aligning right and left in double-sided mode, align the same on the front and back sides, align the right edge when aligning the copy bundle from the front, and align the right edge when aligning left. (3) Page limited mode ○ Both pages (this original reading mode, default) (Function) Copy both left and right pages. Since most of the originals are printed on both sides, page limitation is not used.

(Operation) By pressing the page limit key 621,
Remove page limitation. Right page (function) Spreads only the right page of this document. Used for stapling and single-sided documents such as files. (Operation) By pressing the page limitation key 621, the right page is selected.

Left Page (Function) Spread Only the left page of the original document is copied. Used for right-sided (vertical writing original) single-sided originals. (Operation) The left page is selected by pressing the page limit key 621. * The page-only mode is valid in the independent page mode, and the designation of the copy start page left and right is invalid.

(4) Double-sided mode ○ Single-sided copying (default) (Function) Copies an original image on one side of transfer paper. Both the original document reading mode and the sheet document reading mode are effective. (Operation) Pressing the double-sided key 602 releases the double-sided mode.

Single Sided Original (Function) Sheet original image is copied on both sides of transfer paper. The binding margin distribution in the double-sided mode corresponds to the SP mode as in the conventional device. For the original document, only the page-only mode (single-sided original document) is selected.

(Operation) By pressing the double-sided key 602, the double-sided mode of the single-sided original is selected. For sheet originals, the print key 641 is pressed for each original set, as in a normal copying machine.

Double-sided original (function) A double-sided copy is formed on the front side and the back side of the original.
When the copy start page is the double-page spread left page and the copy end page is the double-page spread right page, one side of the first and last transfer sheets is blank.

High-speed double-sided (double-sided copy productivity about twice that of conventional machines) Only in the 1-to-1 double-sided mode, the output page order is switched using the frame memory, and the image on the right page is displayed on the first transfer paper surface Form it and convey it to the double-sided tray, turn the pages, form the image on the right page on the surface of the second transfer paper, convey it to the double-sided tray, re-feed the first transfer paper, and reverse The image on the left page is formed and discharged. When the number of copies is "2" or more, the transfer sheets are once stacked on the double-sided tray, and the high-speed double-sided mode is not performed.

(Operation) By pressing the double-sided key 602 in the original reading mode, the double-sided mode of the double-sided original is selected. Spread Document (Function) Copies the spread left and right pages of this document on the front and back of the transfer paper. When the copy start page and copy end page are spread left pages, one side of the first and last transfer sheets is blank. Since it is necessary to access each page of the frame memory, the double-sided high speed mode is not executed. For double-sided copying of a two-page spread, the two-sided copy mode is selected in the two-page spread mode.

(Operation) In the original reading mode, the double-sided key 602 is pressed to select the double-sided opening mode of the spread original. * The binding allowance for double-sided mode for this document should be right-aligned and left-aligned, and the front and back sides should be unidirectional. (5) Paper ejection selection ○ Backside paper ejection mode (Main document reading mode / default) (Function) Since this original is scanned in page order, during normal single-sided copying, the copy is reversed and the image surface is ejected downward. To do.

(5) Post-scanning mode After the return operation is completed, the scanning unit 200 is scanned and set at the central home position, and the document table is lowered and retracted from the scanning unit 200 so that the original document can be taken out.

Next, additional page setting will be described. Depending on the structure of chapters and pages in one book manuscript, a page to be captured or a page to be copied may be skipped. This apparatus has an additional page mode for adding page ranges at a plurality of locations, as will be described later. A plurality of page ranges in this document are initially set by a series of page number designation operations.

In this manuscript, the number of pages is usually set, and
The page number is continuous from the first page, and each page range is designated by inputting the copy start page and copy end page as described above. The number of pages is set by sequentially inputting each page range of this document from the first page range, and repeating the page determination and the page addition. When an additional page is input and confirmed by the enter key, this apparatus displays the guidance of the standby mode as shown in FIG. 43 (b) on the guidance display section 643 instead of the guidance of the additional page input, and the start key (Print key) 641
When turned on, the first page range (book 1) is displayed on the guidance display portion 643 as shown in FIG. 43 (c), and reading and output of the image are started.

In this manuscript, according to the structure of chapters and pages,
There is a case where the page to be captured or the image to be copied is skipped. In addition, a blank image or a page that does not require copying may be sandwiched as a page image. In the second page number setting method, an output (copy) page range of the original document is specified, and a page range within the page range that is not output (not copied), that is, a skip page in the original document that does not require output is specified. . For example, first, as described above, the page range is entered by inputting from page 10 to page 55 of this manuscript, and then the page skip page key (not shown) of the operation unit 99 is pressed to set the skip page range to 1.
The 0 key 642 and the enter key 640, for example, the 20th key
Enter from page 45 to confirm. As a result, the system control unit 802 (see FIG. 46), which will be described later, first outputs an image in the page range from page 10 to page 19,
Secondly, the image in the page range from page 46 to page 54 is output, and the image in the skip page range from page 20 to page 45 is not output.

The system control unit 802 causes the guidance display unit 643 of the operation unit 99 to display the order of each page range and the designated page range after setting the additional page or during copying of another page group, and displays the order. The form is the same as the guidance display during the copying operation or in the standby state shown in FIG. System control unit 8
02, the display of the guidance display portion 643 is switched from Book 1 to Book 2 (second page range) and Book 3 (third page range) by pressing the page addition key 634, and the set number of pages is changed. The display is repeated each time the page addition key 634 is pressed. Also, the system control unit 802 is
By pressing the page addition key 634, the next page range is displayed on the guidance display portion 643.

The system control unit 802 reads the page range of each page group and displays it on the guidance display unit 643 by designating the page addition key 634 after inputting the number of pages of a plurality of page groups. Then, in the read display state, the system control unit 802 selects the copy start page to copy end page input mode with the copy page setting key 628, and the page range is changed by re-inputting the page number as described above. Correct the page range for re-entry. Therefore, the system control unit 802, the copy page setting key 628, the 10 key 642, and the enter key 640 constitute a correction means for correcting the number of pages. Further, the system control unit 802 reads the page range of each page group by the addition of the page addition key 634 and displays it on the guidance display unit 643. In this state, the copy page setting key 628 is used to start the copy start page ...
When the copy end page input mode is selected and the number of pages is not input and the enter key 640 is pressed, the additional page mode and the number of pages are canceled. Therefore, the system control unit 80
2, the copy page setting key 628, and the enter key 640 constitute a canceling means for canceling the number of pages.

Next, the guidance display will be described.
The operation guides and warnings of this apparatus are displayed on a guidance display section 643 arranged on the operation section 99, which is a liquid crystal display panel capable of displaying characters in two columns of 20 digits.
FIG. 43 is a display example of the guidance display unit 643. In the guidance display portion 643, the upper left corner displays the reading mode selection state, the upper right corner displays the copy magnification, the lower left corner displays the set number of pages, and the lower right corner displays the number of pages being copied.

FIG. 43A shows a general display example of the guidance display section 643 during copying of the original document. The display content is that the reading mode is the original document reading mode, the copy magnification is the same size, and the set number of pages is the setting from page 15 to page 48 of the right-side spread of the original document. It indicates that copying is in progress. FIG. 43B shows a general display example of the guidance display section 643 during standby for copying the main document. The display content indicates that the reading mode is the original document reading mode, the copy magnification is the same size, and the set number of pages is set to 40 pages in the double-page spread mode. Therefore, the number of pages being copied at the bottom right is not shown.

As described above, in the present apparatus, the page input for designating the copy start page and copy end page of the two-page spread original, or the number of image formations (the number of copies) by the total number of pages is performed, and the setting contents are displayed, The number of set pages can be confirmed and corrected.
Also, when setting the copy start page of the main document by opening the page, the main document is opened by looking at the guidance display section 643 after setting the number of pages. The set number of pages is displayed on the guidance display section 643 at the time of standby before the start of operation and at the end of reading of the original document. The number of set pages and the number of pages being copied are displayed on the guidance display section 643 during reading and copying of the original document.

The apparatus reads the original document, forms an image of the read page, and turns the pages of the original document. This apparatus automatically and continuously operates after the operation is started. The system control unit 802
The guidance display unit 643 displays the set number of pages and the number of pages in which the reading or copying of the original document is being performed to inform the operator of the operation status and progress. Further, when the stop key of the operation unit 99 is pressed, the operation is interrupted or stopped halfway on the page where the reading or copying is being executed.

FIG. 43C shows a general display example of the guidance display section 643 during copying of a sheet document. The display content indicates that the reading mode is the sheet document reading mode and the copy magnification is the same size. Figure 43
(D) shows a display example of the guidance display section 643 during copying of job 1 which is the first page group in the additional page mode for automatically reading a plurality of page groups. The display content is that the reading mode is the reading mode of the first page range (book 1) of the original document, the copy magnification is the same size, and the set number of pages is from the 15th page of the right page of the spread of the original document. It is displayed that the setting is up to 48 pages and that the 24th page is being copied.

FIG. 43 (e) shows a display example of the guidance display portion 643 during copying for job 2 which is the next page group in the additional page mode. The display content is such that the reading mode is the reading mode of the second page range (book 2) of the manuscript, the copy magnification is the same size, and the set number of pages is from the 52nd page of the spread left page of the manuscript. It is displayed that the setting up to page 58 is being made and that page 55 is being copied. Since the input copy start page of the first job is the 15th page and the right page, the successive copy pages of this document are arranged such that odd pages are right pages and even pages are left pages. Therefore, the input copy start page of the second job, page 52, is determined to be the left page, and the copy start page of the guidance display portion 643 is changed to the left page at the time of shifting to the second job.

FIG. 43 (f) shows a display example of the guidance display section 643 during copying of job 3 which is the next page group in the additional page mode. The display content is such that the reading mode is the reading mode of the third page range (book 3) of the manuscript, the copy magnification is the same size, and the set number of pages is from the 65th page to the right page of the spread of this manuscript. It is displayed that page 99 is being set and that page 99 is being copied. Third
The 65th page of the copy start page in which the job is input is determined to be the right page, and the guidance display unit 6 is displayed at the time of shifting to the 3rd job.
Regarding the display of 43, the copy start page is changed to the right page.

FIG. 43 (g) shows a display example of the guidance display section 643 during page skipping from job 2 to job 3 in the additional page mode. The display content is that the reading mode is the reading mode of book 3, the copy magnification is the same size, and the set number of pages is the setting from the 65th page to the 99th page of the right-side spread of this document. It indicates that the page is being turned.

FIG. 44 shows an example of the warning display on the guidance display section 643. In this apparatus, the upper limit value of the skipped page number for performing only page-turning scanning is limited to 10 pages and the number of page-turning scanning times is five. For example, if the page number setting of job 1 is from page 15 to page 48 and the page number setting of job 2 of the additional page is from page 82 to page 98, that page number setting is prohibited. It System control unit 80
2 calculates the difference between the number of skipped pages and the start page of job 2 and the end page of job 1 to reduce the total processing time when automatic and manual operations are compared. Further, the system control unit 802 limits the number of skipped pages to be equal to or less than the upper limit value to reduce the number of turning scans outside the output page range, prevent destruction of the original document, and reduce the probability. In this case, the guidance display unit 643 displays a warning as "skipping page range exceeded", and the input additional page is invalidated and canceled. Since the type of this document differs depending on the user and the range and location of the copied pages vary, the upper limit of the skipped page can be set programmable according to the user, and the upper limit of the skipped page can be set in the SP mode. Can be set to infinity.

The page turning operation without image output requires about 15 seconds in one cycle, whereas it takes several tens of seconds to manually set the two-page spread of the original document and reset the number of pages.
The upper limit of the number of pages that does not output the page image within the page range is 1 as the initial value.
There are 0 pages. The processing speed is improved in a general case when the page turning is automatically compared with the manual operation without the user being aware.

FIG. 45 shows a display example of the guidance display portion 643 during copy page setting. FIG. 45 (a) shows a guidance display for setting a normal copy start page to copy end page, and this is the same as when inputting the first page range when there is an additional page.
As described above, the copy start page to the copy end page are set by inputting the copy start page with the ten key 642 and confirming with the enter key 640, and inputting the copy end page with the ten key 642 and confirming with the enter key 640. FIG. 45B shows a guidance display for setting the page number in the additional page mode, which is the page number setting for book 2. The number of pages is set by inputting the copy start page with the ten key 642 and confirming it with the enter key 640, and inputting the copy end page with the ten key 642 and confirming with the enter key 640 as described above.

In this apparatus, the number of page range groups that can be set by the additional page motes is limited to three groups. Generally, in copying a plurality of portions of one original document, the operation and display become easier to understand as the number of portions increases. Further, if the number of output locations for outputting a copy is one, the number of output locations for outputting a copy of a large number of page groups will be one, and it is necessary to limit the number of page groups.

Next, the additional page mode will be described. In this apparatus, the spread book document is read, the page is turned over, and the image of the read page is output. Further, as described above, by providing the original document page range designating means for designating the page ranges at a plurality of positions of the original document, by continuously forming and outputting images of a plurality of designated page ranges based on the setting of the number of pages, Copy only the desired pages in this manuscript. Further, for pages outside the designated plurality of page ranges, only page turning scanning is performed, and image reading processing is omitted while performing continuous operation.

Further, the present apparatus, as described above, the original document page range designating means for designating a page range at a plurality of places, and the input means for inputting whether the copy start page is the right page or the left page of the spread left and right pages. And the left and right spread pages of the additional page are determined from the left and right of the first copy start page. This is because the system control unit 802 determines whether the first copy start page is the left page or the right page by the flow similar to the final page right / left determination flow shown in FIG. It is calculated based on whether it is an odd number or an even number. In the additional page mode, the second page range and the third page range are additionally input. Second page range and third
The page mode and the other pages have the same copy mode setting.

In this apparatus, the sorter 702 can be optionally installed. The sorter 702 has 10 output bins and is usually used for sorting each part when copying a plurality of copies. In the additional page mode, the transfer paper on which image formation is performed for each page group by continuously copying page ranges at a plurality of locations is sorted 702.
It is output separately for each bin. In addition, this device is a sorter 7
When a plurality of paper discharge ports such as 02 and Doggytail are installed, the standard page discharge is performed in the additional page mode.

Most of the originals are printed on both sides, and when copying them, many machines copy on both sides of the transfer paper.
When copying multiple page ranges on both sides of the transfer paper, this machine copies the specified multiple page ranges on the front and back sides of the transfer paper, and creates a series of copies without making empty pages. Have. If the continuous page mode is designated by the operation unit 99, when copying of the last page of the first page group is completed on the front surface of the transfer paper, copying from the first page of the next page group is executed from the back surface of the transfer paper. It is performed continuously.

In this apparatus, the forward scanning of the scanning unit 200 for a page which does not output an image does not read the page image. That is, the scanner control unit 801 (see FIG. 46) turns off the lamps 201 and 202 for illuminating the main document, stops the CCD drive signal for reading the main document, processes the image signal, and frames the image signal. Memory 10
It is assumed that the storage in 4 is stopped. Further, the system control unit 802 causes the printer 501 to stop the image forming process and driving for image formation during the page skip period.

Next, the page skip mode will be described. FIG. 46 shows the system configuration of this apparatus. The scanner control unit 801 as the scanner control unit is configured by the IPU 103, and the system control unit 80 as the system control unit
2 and a plotter control unit 803 as plotter control means
Is composed of a main control plate 107. The scanner control unit 801 controls the scanner unit 500, and the plotter control unit 803 controls the printer (plotter) 501.
The operation control unit 804 as the operation control unit is the operation unit 99.
The operation state of each operation key including the mode input key used in the above-described additional page setting is notified to the system control unit 802 in the operation unit 99. System control unit 80
Reference numeral 2 indicates to the operation control unit 804 that the buzzer is turned on / off based on the key information from the operation control unit 804, each light emitting diode of the operation unit 99 is turned on / off, and the content to be displayed on the guidance display unit 643 is notified to the operation control unit 804. Confirm the mode corresponding to the key operation. The operation control unit 804 is the system control unit 80.
2) Buzzer on / off, operation unit 99
ON / OFF of each light emitting diode of the, guidance display unit 6
The display content of 43 is controlled.

As described above, when the system control unit 802 exchanges information with the operation control unit 804 to perform the basic setting of the copy-enabling mode as described above, and the setting is completed,
The system control unit 802 displays on the operation control unit 804 that the copy is possible by the light emitting diode of the operation unit 99, the guidance display unit 643, and the like, and waits for a copy start command from the operator (pressing the print key 641 or the like). .

When the operator presses the print key 641, the system controller 802 checks the set mode and checks the scanner controller 801 and the plotter controller 8.
03 communicates the data needed to implement that mode. Hereinafter, the operation of the additional page mode will be described based on the fact that the system control unit 802 synchronizes the scanner control unit 801 and the plotter control unit 803 in this way.

47 to 49 show a page skip mode operation flow of the system controller 802. System control unit 80
When the print key 641 is pressed when the page skip mode is set, No. 2 notifies the scanner control unit 801 of parameters relating to the image (density, white spot amount, movement amount, etc.) and issues a scan start command. Scanner control unit 80
When receiving a scan start command from the system control unit 802, the first unit scans the scanning unit 200 to start reading an original image, and writes the read image data in the frame memory 104.

The system control unit 802 determines whether or not the copy start page set at the time of issuing this scan start command is the left page, and if the copy start page is the left page, the page control counter (page count) is set to 2 Is set to set the image data storage of the frame memory 104 to start from the left page image data, and if the copy start page is the right page, set the page management counter to 1 to store the image data of the frame memory 104. Set to start from the right page image data storage position.

The scanner control unit 801 includes the scanner unit 50.
When the reading of the document image of 0 is completed, the return mode is set, and the page turning process of the scanner unit 500 is performed.
Further, when the page turning process of the scanner unit 500 fails, the scanner control unit 801 causes the scanner unit 500 to repeatedly perform the page turning process, and notifies the system control unit 802 of the success or failure. The system control unit 802 counts the number of times (the number of retries) of the page turning process of the scanner unit 500 based on the notification from the scanner control unit 801, and when the number becomes equal to or more than a predetermined page turning error number, the page turning is performed. It is judged that an error has occurred and EMERGEN
It shifts to CY mode and performs emergency processing for page turning errors.

When the page turning process is completed, the scanner control section 801 notifies the system control section 802 of "successful page turning". When the system control unit 802 receives the notification of “successful page turning” from the scanner control unit 801, it adds 2 to the page management counter. By doing so, the count value of the page management counter represents the number of pages to be scanned (image is read) by the scanner unit 500.

Further, the system control unit 802 issues print parameters (paper feed stage, paper ejection port, process conditions, etc.) to the plotter control unit 803 when a scan start command is issued. In this case, the system control unit 802 manages the set mode, recognizes the paper feed stage (paper feed device) for each page in the printer 501, the paper discharge port to the sorter 702, and controls the plotter. Print parameters for a plurality of (N) pages are issued to the unit 803.

When the plotter control unit 803 receives the print parameters for N pages from the system control unit 802, the plotter control unit 803 temporarily stores the print parameters in the buffer, and first controls the printer 501 based on the print parameters of the first page to control the first page. Start feeding the eyes. In the paper feeding operation for the second and subsequent pages of the printer 501, the plotter control unit 803 controls the F of the previous transport paper.
Control is performed based on the gate assert timing (timing at which an image is transferred onto the conveyed paper), and the paper conveyance process can be performed at the shortest paper interval.

The system control unit 802 determines whether or not the conveyed paper from the paper feeding device reaches the registration roller by the input signal from the registration sensor which detects the conveyed paper at the registration roller, and the conveyed paper is registered. A page memory start request is issued to the scanner control unit 801 when the plotter 501 reaches the roller and the scanner unit 500 is synchronized (at the F gate assert timing). In this case, the system control unit 802 determines whether to print the image data of the right page or the image data of the left page by the plotter, and according to the result, the scanner control unit 801 outputs the right data for the page memory (frame memory 104). Issue a page memory start request for page or left page.

The scanner controller 801 is the frame memory 1
In step 04, the image data of the right page or the left page requested by the page memory start request is output in synchronization with the printer 501. In the printer 501, an image is written on the photoconductor drum 706 by image exposure by the exposure unit based on the image data output from the frame memory 104 as described above, and an image on the photoconductor drum 706 is formed on the conveyance paper from the registration rollers. Is transferred, and the conveyed paper is discharged to the outside or the double-sided tray 720. In this case, the printer 5
01 detects the conveyed paper discharged to the outside or the double-sided tray 720 by the paper discharge sensor, and notifies the system control unit 802 of the paper detection signal from this paper discharge sensor.

The system control unit 802 determines whether or not the transfer paper is discharged to the outside or the double-sided tray 720 by the printer 501 based on the paper detection signal from the paper discharge sensor and determines whether the transfer paper is the outside or the double-sided tray 720. When it is discharged to either of the above, 1 is added to the discharge counter. Further, the transfer paper is transferred to the outside and the double-sided tray 7 in the printer 501.
When the sheet is discharged to any one of 20, the print parameter buffer has a space for one sheet, so the system control unit 8
02 determines whether or not the value of the discharge counter has reached the total number of I-th page ranges currently being copied, and the value of the discharge counter does not reach the total number of I-th page ranges currently being copied. In the case, the plotter control unit 803 (N + value of discharge counter)
Issue the second print parameter. By doing so, since the print parameter buffer of the plotter control unit 803 always has print parameters for N sheets, the shortest sheet interval is maintained until the end.

When the value of the discharge counter reaches the total number of the I-th page range currently being copied, the system control unit 802 adds 1 to the value of the discharge counter to set the next page. It is determined whether or not the I-th page range is set, and if the next page range is not set, it is confirmed and the copying operation is ended.
In this case, since the plotter control unit 803 does not set the I-th page range, the print parameter buffer becomes empty at the time of feeding the last page, and thus the printer 501 ejects the sheet on which the image of the last page is formed. Operation is stopped after being done. When the I-th page range is set, the system control unit 802 turns on the page skipping mode to notify the scanner control unit 801 that the page skipping mode is set, and also causes the scanner control unit 801 to start scanning. Issue a directive.

For example, the page range is from page 10 to page 54, from page 10 to page 19, and from page 46 to page 54.
When it is set to output up to pages but not output from page 20 to page 45, the value of the discharge counter becomes equal to the total number of pages from page 10 to page 19 (10 pages). The above control is repeated until. When the value of the ejection counter becomes equal to 10 pages, the system control unit 802 determines whether the next page is set. In this example of setting the number of pages, the pages 46 to 54 are set to be output next, so the system controller 802 turns on the page skipping mode and causes the scanner controller 801 to skip the pages. And the scanner control unit 80
Issue a scan start command to 1.

The scanner control section 801 receives the scan start command from the system control section 802 and causes the scanning unit 200 to scan to perform page turning processing. In the page skip mode, the scanner unit 500 does not need to read the main document image, and the scanner control unit 801 may notify the system control unit 802 of “successful page turning” and “scanner ready for next scan start command”.

When the scanner controller 801 receives the page skip mode notification from the system controller 802, it sets the scanning speed of the scanning unit 200 to a high scanning speed, and
The loads of the lamps 200, 201 and the like necessary for reading the original document are turned off. The scanner control unit 801 causes the scanner unit 500 to perform the page turning and the blank scan of the main document by the high-speed scanning of the scanning unit 200 as shown in FIG. Until the notification from the system control unit 802 that the page skipping mode has ended is received.

When the page turning process of the scanner unit 500 fails, the scanner control unit 801 causes the scanner unit 500 to repeatedly perform the page turning process, and notifies the system control unit 802 of the result. System control unit 80
2 is a notification from the scanner control unit 801 to notify the scanner unit 5
The number of times the page turning process is repeated (count of retries) of 00 is counted. If the number of times exceeds a predetermined number of page turning errors, it is determined that a page turning error has occurred and the mode is changed to the EMERGENCY mode and the page turning is performed. Perform emergency processing for errors.

When the page turning process is completed, the scanner control section 801 notifies "page turning successful". When the system control unit 802 receives the notification of “successful page turning” from the scanner control unit 801, it adds 2 to the page management counter. The scanner control unit 801 issues a scanner ready for the next scan start command to the system control unit 802 after the page turning process is completed. In the page skipping mode, the scanner control unit 801 causes the scanning unit 200 to scan by the scan start command from the system control unit 802 to perform page turning processing. However, in the page skip mode, the F gate assert timing does not occur because the plotter 501 is not operating, and the system control unit 80
In 2, the scanner controller 801 issues only "page turning success" and the scanner ready for the next scan start command.

The system control unit 802 is the scanner control unit 8
The page management counter issues the page count and the scan start command in the page skipping mode in response to the "page turning success" from 01 and the notification of the scanner ready for the next scan start command. The page management counter represents the number of pages to be scanned by the scanner unit 500. The left page of the double-page spread original is (page management counter value-1) page, and the right page of the double-page spread original is (value of the page management counter. ) It becomes a page.

From this, (value of page management counter −
1) The page skipping mode ends under the condition of ≧ 46. The system control unit 802 displays (value of page management counter-
1) determines whether or not the page skipping mode has ended by determining whether or not the page start mode of the I-th page range is equal to the copy start page. In the above page number setting example, (the value of the page management counter- 1) Under the condition of ≧ 46, it is determined whether or not the page skipping mode has ended.

If the condition of (value of page management counter-1) ≧ 46 is not satisfied, the system control unit 802 receives a “page turning success” from the scanner control unit 801 and a scanner ready notification for the next scan start command. The page management counter issues a page count and issues a scan start command, and if the condition of (page management counter value-1) ≧ 46 is satisfied, it is determined that the page skipping mode has ended.

When the page skipping mode ends, the system control unit 802 determines whether (copy management counter value -1) and the copy start page of the I-th page range are equal to each other to start the copy. It is determined whether the page is the left page or the right page. For example, in the above-described page number setting example, the system control unit 802 sets (page management counter value-1) = 46 for the copy operation from page 46 to page 54 of the original document.
Then, if the copy start page is the left page (value of page management counter) = 46, it is determined that the copy start page is the right page.

When the page skipping mode is completed, the system controller 802 notifies the scanner controller 801 that the page skipping mode has been completed.
In order to notify the plotter 501 of the print parameters up to page 4, the scan start flag indicating that the scan start of the next scanning unit 200 is the first scan start is turned on, and the scanner controller 801 is notified of the parameter relating to the image. Return to the step to do.

In the example of setting the number of pages, the system control unit 8
02, similarly, the plotter 501 is from page 46 to page 54.
When the copies up to the page are discharged, it is determined whether the discharge counter has reached the total number of the I-th page range currently being copied, and the discharge counter has reached the total number of the I-th page range currently being copied. In that case, 1 is added to the discharge counter to judge whether the next page is set or not. If the next page range is not set, it is confirmed and the copying operation is ended.
In this case, the plotter control unit 803 stops the operation after the last page of paper is discharged by the printer 501 because the print parameter buffer becomes empty when the last page is fed because the next page range is not set.

As shown in FIG. 47 (b), the system control unit 802 always has three conditions during the copying operation: the next scan start timing of the scanner unit 500, the scanner ready state, and the memory ready state of the frame memory 104. It is checked whether or not the condition is satisfied, and when these conditions are satisfied, the process returns to the step of notifying the scanner control unit 801 of the parameter regarding the image.

Next, the application mode related to the additional page mode will be described. As described above, the operation control unit 804
The operation state of each operation key including the mode input key used for additional page setting in the operation unit 99 is notified to the system control unit 802. The system control unit 802 is the operation control unit 804.
ON / OFF of the buzzer based on the key information from the operation unit 99
ON / OFF of each light emitting diode of the, guidance display unit 6
The contents to be displayed in 43 are notified to the operation control unit 804, and the mode corresponding to the key operation is confirmed. The operation control unit 804 controls on / off of the buzzer, on / off of each light emitting diode of the operation unit 99, and display contents of the guidance display unit 643 according to the notification from the system control unit 802.

When the system control unit 802 completes the basic setting of the copy-enabling mode as described above by exchanging information with the operation control unit 804, the system control unit 802 can copy the operation control unit 804. The state is indicated by the light emitting diode of the operation unit 99 and the guidance display unit 64.
3 and the like, and waits for a copy start command from the operator (pressing the print key 641 or the like).

The system controller 802 uses the print key 6
When 41 is pressed, the set mode is checked and the scanner control unit 801 and the plotter control unit 803 are notified of the data necessary for realizing the mode.
Hereinafter, the operation of the application mode will be described based on the fact that the system control unit 802 synchronizes the scanner control unit 801 and the plotter control unit 803 in this way.

50 to 52 show an application mode operation flow of the system control unit 802. System control unit 802
Is the print key 6 by the operator when setting the application mode.
When 41 is pressed, the scanner control unit 801 is informed of parameters relating to the image (density, amount of blank area, amount of movement, etc.) and issues a scan start command. Upon receiving the scan start command from the system control unit 802, the scanner control unit 801 scans the scanning unit 200 to start reading the original image, and writes the read image data in the frame memory 104.

The system control unit 802 determines whether the copy start page at the time of issuing this scan start command is the left page, and if the copy start page is the left page, sets 2 in the page management counter and sets the frame. The image storage of the memory 104 is set to start from the left page image data, and if the copy start page is the right page, the page management counter is set to 1 and the image storage of the frame memory 104 is started from the right page. Set.

The scanner control section 801 is a scanner section 50.
When the reading of the document image of 0 is completed, the return mode is set, and the page turning process of the scanner unit 500 is performed.
Further, when the page turning process of the scanner unit 500 fails, the scanner control unit 801 causes the scanner unit 500 to repeatedly perform the page turning process, and notifies the system control unit 802 of the result. The system control unit 802 counts the number of times (the number of retries) of the page turning process of the scanner unit 500 based on the notification from the scanner control unit 801, and when the number becomes equal to or more than a predetermined page turning error number, the page turning is performed. It is judged that an error has occurred and EMERGEN
It shifts to CY mode and performs emergency processing for page turning errors.

When the page turning processing is completed, the scanner control section 801 notifies the system control section 802 of "successful page turning". When the system control unit 802 receives the notification of “successful page turning” from the scanner control unit 801, it adds 2 to the page management counter. By doing so, the count value of the page management counter represents the number of pages to be scanned (image is read) by the scanner unit 500.

Further, the system control unit 802 issues print parameters (paper feed stage, paper ejection port, process conditions, etc.) to the plotter control unit 803 when a scan start command is issued. In this case, the system control unit 802 manages the set mode, recognizes the paper feed tray for each page in the printer 501, the paper discharge port to the sorter 702, and so on, and the plotter control unit 803 detects N pages. Issue print parameters for minutes.

When the plotter control unit 803 receives the print parameters for N pages from the system control unit 802, the plotter control unit 803 temporarily stores the print parameters in the buffer, and first controls the printer 501 based on the print parameters for the first page to control the first page. Start feeding the eyes. In the paper feeding operation for the second and subsequent pages of the printer 501, the plotter control unit 803 controls the F of the previous transport paper.
Control is performed based on the gate assert timing (timing at which an image is transferred onto the conveyed paper), and the paper conveyance process can be performed at the shortest paper interval.

The system control unit 802 determines whether or not the conveyed paper from the paper feeding device reaches the registration roller by the input signal from the registration sensor which detects the conveyed paper at the registration roller, and the paper feeding device When the sheet of paper reaches the registration rollers and the plotter 501 and the scanner unit 500 are synchronized (at the F gate assert timing).
A page memory start request is issued to the scanner control unit 801. In this case, the system control unit 802 determines whether to print the image data of the right page or the image data of the left page by the plotter, and according to the result, the scanner control unit 801 outputs the right data for the page memory (frame memory 104). Issue a page memory start request for page or left page.

The scanner control unit 801 is the frame memory 1
In step 04, the image data of the right page or the left page requested by the page memory start request is output in synchronization with the printer 501. In the printer 501, an image is written on the photoconductor drum 706 by image exposure by the exposure unit based on the image data output from the frame memory 104 as described above, and an image on the photoconductor drum 706 is formed on the conveyance paper from the registration rollers. Is transferred, and the conveyed paper is discharged to the outside or the double-sided tray 720. In this case, the printer 5
01 detects the conveyed paper discharged to the outside and the double-sided tray 720 by the paper discharge sensor, and notifies the system control unit 802 of the paper detection signal from this paper discharge sensor.

The system control unit 802 determines whether or not the transfer paper is ejected to the outside by the printer 501 based on the paper detection signal from the paper ejection sensor, and when the transfer paper is ejected to the outside, the copying operation currently being performed. Check which page setting mode is the copy operation, and specify the sheet discharge port corresponding to that page setting mode (I-th page setting mode).
In addition, the system control unit 802 determines whether the transfer paper is discharged to the outside or the double-sided tray 720 by the printer 501 based on the paper detection signal from the paper discharge sensor to determine whether the transfer paper is to the outside or the double-sided tray 720. When it is discharged to any one, 1 is added to the discharge counter.

When the transfer paper is discharged to the outside or the double-sided tray 720 by the printer 501, a space for one sheet is created in the print parameter buffer. Therefore, the system control unit 802 causes the discharge counter to copy the I-th copy current copy. If the discharge counter does not reach the total number of the I-th page range currently being copied by judging whether or not the total number of the page range of the second time has been reached, the plotter control unit 803 outputs the (N + value of the discharge counter) th Issue print parameters. By doing so, since the print parameter buffer of the plotter control unit 803 always has print parameters for N sheets, the shortest sheet interval is maintained until the end.

When the value of the discharge counter reaches the total number of the I-th page range currently being copied, the system controller 802 adds 1 to the value of the discharge counter to set the next page. It is determined whether or not the I-th page range is set, and if the next page range is not set, it is confirmed and the copying operation is ended.
In this case, since the plotter control unit 803 does not set the I-th page range and the print parameter buffer becomes empty when the last page is fed, the plotter controller 803 operates after the last page of paper is ejected by the printer 501. Stop. When the I-th page range is set, the system control unit 802 turns on the page skipping mode to notify the scanner control unit 801 that the page skipping mode is set, and also causes the scanner control unit 801 to start scanning. Issue a directive.

For example, the page range is from page 10 to page 54, from page 10 to page 19, and from page 46 to page 54.
When it is set to output up to pages 20 and not to output pages 45 to 45, the above-mentioned process is performed until the discharge counter becomes equal to the total number of pages 10 to 19 (10 pages). The control is repeated. When the discharge counter becomes equal to 10 pages, the system control unit 802 determines whether the next page is set. In this example of setting the number of pages, the pages 46 to 54 are set to be output next, so the system controller 802 turns on the page skipping mode and causes the scanner controller 801 to skip the pages. This is notified and a scan start command is issued to the scanner control unit 801.

The scanner control section 801 receives the scan start command from the system control section 802 and causes the scanning unit 200 to scan to perform page turning processing. In the page skip mode, the scanner unit 500 does not need to read the main document image, and the scanner control unit 801 may notify the system control unit 802 of “successful page turning” and “scanner ready for next scan start command”.

Upon receipt of the page skipping mode notification from the system control unit 802, the scanner control unit 801 sets the scanning speed of the scanning unit 200 to a high scanning speed, and
Turn off the load such as the lamp required to scan this document. The scanner control unit 801 causes the scanner unit 500 to perform the page turning and the blank scanning of the main document by the high-speed scanning of the scanning unit 200 without reading the main document by the above-described processing, and the system control unit 802 performs this. Continue until you receive the notification that the page-skipping mode has ended.

When the page turning process of the scanner unit 500 fails, the scanner control unit 801 causes the scanner unit 500 to repeatedly perform the page turning process, and notifies the system control unit 802 of the result. System control unit 80
2 is a notification from the scanner control unit 801 to notify the scanner unit 5
The number of times the page turning process is repeated (count of retries) of 00 is counted. If the number of times exceeds a predetermined number of page turning errors, it is determined that a page turning error has occurred and the mode is changed to the EMERGENCY mode and the page turning is performed. Perform emergency processing for errors.

When the page turning processing is completed, the scanner control section 801 notifies "page turning succeeded" and "scanner ready for the next scan start command". When the system control unit 802 receives the notification of “successful page turning” from the scanner control unit 801, it adds 2 to the page management counter. In the page skipping mode, the scanner control unit 801 causes the scanning unit 200 to scan by the scan start command from the system control unit 802 to perform page turning processing. However, in the page skipping mode, the F gate assert timing does not occur because the plotter 501 is not operating, and the system control unit 802 has the scanner control unit 801.
Only "success in page turning" and "scanner ready for next scan start command" are issued.

The system controller 802 is the scanner controller 8
In response to the notification of "successful page turning" from 01 and "scanner ready for next scan start command", the page management counter issues a page count and a scan start command in the page skip mode. The page management counter represents the number of pages to be scanned by the scanner unit 500, and the left page of the two-page spread original is (page management counter value-1) pages.
The right page of the two-page spread original is the (value of page management counter) page.

From this, (value of page management counter −
When 1) becomes equal to the copy start page of the I-th page range, the page skipping mode ends. In the above page number setting example, page skipping is performed under the condition of (value of page management counter-1) ≧ 46. The mode will end. The system control unit 802 determines whether the page skipping mode has ended by comparing (page management counter value -1) with the copy start page of the I-th page range, and the page number setting example described above. Then, by comparing (value of page management counter-1) and 46, it is determined whether or not the page skipping mode has ended.

If the condition (value of page management counter-1) ≥46 is not satisfied, the system control unit 802 determines whether "page turning is successful" or "scanner ready for next scan start command" from the scanner control unit 801. Upon notification, the page management counter issues a page count and issues a scan start command, and if the condition of (page management counter value −1) ≧ 46 is satisfied, it is determined that the page skipping mode has ended.

When the page skipping mode ends, the system controller 802 determines whether (page management counter value -1) and the copy start page of the I-th page range are equal to each other to start the copy. It is determined whether the page is the left page or the right page. For example, in the above-described page number setting example, the system control unit 802 sets (page management counter value-1) = 46 for the copy operation from page 46 to page 54 of the original document.
Then, if the copy start page is the left page (value of page management counter) = 46, it is determined that the copy start page is the right page.

When the page skipping mode ends, the system controller 802 notifies the scanner controller 801 that the page skipping mode has ended, and the following pages 46 to 5 are executed.
In order to notify the plotter 501 of the print parameters up to page 4, the scan start flag indicating that the scan start of the next scanning unit 200 is the first scan start is turned on, and the scanner controller 801 is notified of the parameter relating to the image. Return to the step to do.

At this time, the system controller 802 determines whether or not the transfer sheet of the previous job remains in the duplex unit 720, and also determines whether the duplex filling mode is set. Then, the system control unit 802
If the transfer paper of the previous job remains in the duplex unit 720 and the duplex filling mode is set, the image of the first page of the next job is printed in the duplex unit 720.
Set the print parameters so that the transfer is performed on the back side of the remaining transfer paper.

In the above-described page number setting example, similarly, the system control unit 802 causes the plotter 501 to move from page 46 to page 54.
When the copies up to the page are ejected, it is determined whether the value of the ejection counter has reached the total number of the I-th page range currently being copied, and the value of the ejection counter is changed to the I-th page range currently being copied. When the total number of pages is reached, 1 is added to the discharge counter to determine whether or not the next page is set. If the next page range is not set, check it to confirm the copy operation. To finish. In this case, the plotter control unit 803 stops the operation after the last page of paper is discharged by the printer 501 because the print parameter buffer becomes empty when the last page is fed because the next page range is not set.

As shown in FIG. 50B, the system control unit 802 always satisfies the following three conditions: the next scan start timing of the scanner unit 500, the scanner ready, and the memory ready of the frame memory 104 during the copying operation. If these conditions are satisfied, the process returns to the step of notifying the scanner control unit 801 of the parameters relating to the image.

FIG. 53 shows a processing flow of the scanner control section 801 in the application mode. The scanner control unit 801 determines whether or not the page skip mode notification has been received from the system control unit 802, and if the page skip mode notification is not received, the scanner control unit 801 operates normally in the scanner unit 500 (for reading the original document image and (Page turning of this document) is executed, and when the notification of the page skipping mode is received, the scanner unit 500 receives the notification of the scan start command from the system control unit 802.
Set the scanning speed of to the high scanning speed for page skipping mode,
The scanner unit 500 is set to the non-reading mode in which the lamps 201 and 202 are turned off and the main document is not read, and the scanning of the scanner unit 500 is started. Therefore, the scanner unit 500 scans the scanning unit 200 to turn the page of the original document, and does not read the original document with the lamps 201 and 202 turned off.

Further, the scanner control unit 801 determines whether or not the page skip mode cancellation notification is received from the system control unit 802, and if the page skip mode cancellation notification is not received, then the scanner unit 500 is operated as described above. Then, the scanner unit 500 is caused to perform a normal operation when the system control unit 802 notifies the page skip mode release.

This apparatus is an example in which the invention described in claim 1 is applied, and is a book having a scanner section 500 which also serves as a reading means for reading a two-page spread original document and a page-turning means for turning the pages of the original document. In the original image forming apparatus, the page for image formation of this original is displayed with the 10 key 642, the enter key 64.
The original manuscript page designating unit consisting of 0 sets the page range to be image-formed at a plurality of positions in the manuscript, and the manuscript page range designation consisting of copy page setting key 628, page addition key 634, 10 key 642 and enter key 640. Since it is designated by the means, it is possible to input a plurality of page portions in the original document, and a series of page number designation operation can be performed by initial setting. This makes it necessary for the operator to open the image forming start page of the page group and set it, or to specify the number of pages in the page group to start the operation every time image formation of each page group is attached to the machine. It becomes possible to specify the page easily.

Further, this apparatus is an example in which the invention described in claim 2 is applied, and the page range of image formation at a plurality of places in this document is set as copy page setting key 628, 10 key 642, enter key 640, page. Since the start page and the end page of the page range for each image formation are designated by the book page range designating means including the additional key 634, a plurality of page groups can be formed in one book manuscript depending on the structure of chapters and pages. When images are formed or pages to be imaged are skipped, the page range of image formation at multiple locations can be specified by inputting the start page and the end page, and the pages for image formation can be specified. It can be done easily and accurately.

Further, this apparatus is an example in which the invention described in claim 3 is applied, and page range input means comprising copy page setting key 628, 10 key 642 and page addition key 634 as the original page range designating means. And an enter key 640 and a copy page setting key 628 are used to input one image forming page range by the page range inputting means and to press the input confirming key of the input image forming page range. Since the page ranges for image formation at a plurality of points in the original document are specified by sequentially repeating the above steps for each page range for reading or image formation, it is possible to specify a plurality of pages in the original document by the same simple operation as specifying a single page group. It is possible to specify a page range for image formation at a location.

Further, this apparatus is an example in which the invention described in claim 4 is applied, and copy page setting keys 628, 10 key 6
42, enter key 640, and page addition key 634, the order of page ranges for image formation at a plurality of locations designated by the original document page range designation means, copy page setting keys 628, and 10 key 64.
2. Since the operator confirms the page range of the image formation designated by the original document page range designation means including the enter key 640 and the page addition key 634 by the guidance display section 643 as a confirmation means, the operator makes a mistake in inputting each page range. It is possible to reduce the error in image formation and the error in copying.

Further, this apparatus is an example in which the invention described in claim 5 is applied, and copy page setting keys 628, 10 key 6
42, enter key 640, and page addition key 634 to correct or cancel the page range of the image formation designated by the original document page range designation means. Copy page setting keys 628, 10 key 64
2, correction means 628, 642, 640 consisting of an enter key 640 and a system control unit 802 or a copy page setting key 628, an enter key 640, a system control unit 80
Since it is performed by the releasing means consisting of 2, it is possible to eliminate an image forming error or a miscopy due to a page range input error in image forming at a plurality of places, and to correct the designation of another page range after starting the image reading of a certain page range. Or you can cancel it.

Further, this apparatus is an example in which the invention described in claim 6 is applied, and includes a scanner section 500 which also serves as a reading means for reading a two-page spread original document and a page-turning means for turning pages of the original document. In this original document image forming apparatus,
Copy page setting keys 628, 10 key 642, enter key 640,
A page skip key is designated by the first original document page range designating means consisting of a page addition key 634, and a page skipping key is used for a page range in which no image is formed within the image forming page range designated by the first original document page range designating means. 10 key 642, enter key 640
Since it is specified by the second book page range specifying means consisting of
It is possible to easily input a page range that does not require output. When an image is formed on a group of pages or the pages to be imaged are skipped due to the structure of chapters or pages in one book, especially if there is a blank page in the output page range or a page that does not require output. In the case where a sheet of paper is sandwiched, it is possible to easily instruct not to output a small amount of blank paper or pages that do not require output.

In another example of the present original image forming apparatus to which the present invention is applied, the page turning time of skipped pages is reduced in the above example. The two-page spread original document is read by the scanning unit 200 in the forward direction scanning, and the main document page is turned by the scanning unit 200 in the backward direction scanning.
By repeating the reciprocal scanning of, the page images in the page range at a plurality of locations are continuously output. Normally, the forward scanning line speed is 90 mm / sec. The forward scanning of the scanning unit 200 for the skipped page that does not output an image is 180 mm / sec. Is. As a result, the scanning time for skipping pages was halved from 7 seconds to 3.5 seconds.
The page turning time of the cycle is changed from 15 seconds to 11.5 seconds, and the productivity in the additional page mode is increased by about 23%.

Although the example in which the present invention is applied to the original document image forming apparatus has been described, the present invention has an original document image having a reading unit for reading a spread original document and a page turning unit for turning pages of the original document. The same effect can be obtained as when the present invention is applied to the original document image forming apparatus by applying the same to the reading apparatus to specify the image reading page of the original document.

Further, although the example of the above-described original document image forming apparatus is intended for a left original (left cover) original document with a relatively high ratio of horizontal writing, there is also a vertical original right page original document. The above-described example of the original document image forming apparatus may be arranged symmetrically in the case of a vertically written right-turning original document, and the left and right pages are opposite to the above. Therefore, in the above-described example of the original document image forming apparatus, the one in which the left and right pages and the end portions are different is included in the present invention.
